    Health risk assessment (HRA) is the process used to estimate adverse health effects on humans. The importance and sensitivity of food chains to HRA have been observed, but the impact of the transportation of food has generally been ignored. This study developed an exposure assessment to demonstrate the significance of the transportation of agricultural products in HRA. The associated case study estimated the health risks derived from various sources of arsenic emissions in Taiwan. Two assessment scenarios, self-sufficiency and transportation of agricultural products, were compared to calculate risk transfer ratios that show the impact of agriculture transportation. The risk transfer ratios found by the study range from 0.22 to 42.10, indicating that the quantity of transportation of agricultural products is the critical factor. High air deposition and high agricultural production are the two main contributors to the effect of the transportation of agricultural products on HRA. Risk reduction measures could be applied to high-pollution areas as well as to areas with high agricultural productivity to reduce ingestion risks to residents. Certain areas that are sensitive to the transportation of agricultural products may incur more risks if emissions increase in agriculturally productive counties. Copyright © 2014 Elsevier Ltd.

    Gamma and electron radiation effects on wheat straw, oat straw, barley straw, rye straw and dried green fodder are reported. In vitro and in vivo studies show that the digestibility of these agricultural by-products with high fibre content can be increased up to 80% and more at high doses. The increase of the digestibility is connected with a depolymerization of the cellulose and hemicellulose. (author)

    A need to increase agricultural production across the world to ensure continued food security appears to be at odds with the urgency to reduce the negative environmental impacts of intensive agriculture. Around the world, intensification has been associated with massive simplification and uniformity at all levels of organization, i.e., field, farm, landscape, and region. Therefore, we postulate that negative environmental impacts of modern agriculture are due more to production simplification than to inherent characteristics of agricultural productivity. Thus by enhancing diversity within agricultural systems, it should be possible to reconcile high quantity and quality of food production with environmental quality. Intensification of livestock and cropping systems separately within different specialized regions inevitably leads to unacceptable environmental impacts because of the overly uniform land use system in intensive cereal areas and excessive N-P loads in intensive animal areas. The capacity of grassland ecosystems to couple C and N cycles through microbial-soil-plant interactions as a way for mitigating the environmental impacts of intensive arable cropping system was analyzed in different management options: grazing, cutting, and ley duration, in order to minimize trade-offs between production and the environment. We suggest that integrated crop-livestock systems are an appropriate strategy to enhance diversity. Sod-based rotations can temporally and spatially capture the benefits of leys for minimizing environmental impacts, while still maintaining periods and areas of intensive cropping. Long-term experimental results illustrate the potential of such systems to sequester C in soil and to reduce and control N emissions to the atmosphere and hydrosphere.

    1983-01-01

    The relationship between population pressure or density and agricultural productivity is examined by analyzing the changes in the land-man ratio and the changes in the level of land yield in the 17 districts of Bangladesh from 1961-64 and 1974-77. The earlier years were pre-Green Revolution, whereas in the later years new technology had been introduced in some parts of the country. Net sown area, value of total agricultural output, and number of male agricultural workers were the main variables. For the country as a whole, agricultural output grew by 1.2%/year during 1961-64 to 1974-77, while the number of male agricultural workers grew at 1.5%/year. The major source of agricultural growth during the 1960s was found to be increased land-yield associated with a higher ratio of labor to land. The findings imply that a more intensified pattern of land use, resulting in both higher yield and higher labor input/unit of land, is the main source of growth of output and employment in agriculture. There is very little scope for extending the arable area in Bangladesh; increased production must come from multiple cropping, especially through expansion of irrigation and drainage, and from increases in per acre yields, principly through adoption of high yield variants, which explained 87% of the variation in output per acre during the 1970s. Regional variation in output was also associated with variation in cropping intensity and proportion of land given to high yield variants. There is considerable room for modernizing agricultural technology in Bangladesh: in 1975-76 less than 9% of total crop land was irrigated and only 12% of total acreage was under high yield variants. The adoption of new food-grain technology and increased use of high yield variants in Bangladesh's predominantly subsistence-based agriculture would require far-reaching institutional and organizational changes and more capital. Without effective population control, expansion of area under high yield

    Full Text Available Lack of capital has been identified as one of the constraints that faced by small scale farmers. The aim of this research was to examine the effect of agricultural credit on the agriculture production, and calculate the inputs and outputs among small scale farmers. Structured questionnaires were distributed to 136 farmers, who had been selected using the stratified random sampling technique, and the data obtained were summarized into percentages. Regression analysis was adopted to assess the impacts of socio-economic factors on loan size among farmers, while Cobb-Douglas Production Function Analysis (CDPFA was used to test the relationship between key independent variables such as loan amount, farm size, inputs and farm output as dependent variable. The analysis revealed a significantly high value of coefficient of determination (R2= 0.922 that reflected a high relationship between the dependent variable and the independent variables; gender, age, education, family size, farm size, farming experience. The Adjusted (R2 coefficient (R2 = 0.918 revealed that 91.8 % of variation in loam size explained by the changes in variables. The results showed a significance in F-test in size of loan. The hypothesis two, exhibited that the independent variables; loan size, farm size, and inputs explained the variation in the total value of farmers output. The study therefore showed that to achieve the positive agricultural credit impacts on agricultural production, The Government and the private sector should regularly and timely facilitate the credit to the small scale farmers.

    With the improvement of living standards, people pay more attention to the agricultural products with health protection function, and the selenium-rich agricultural products attract more and more consumers. The main biological role of selenium is to resist oxidation and inflammatory response, mainly focusing on resisting aging, preventing cardiovascular disease, protecting eyesight, counteracting or destroying the toxic properties, preventing cancer and thyroid disease. In most areas of China, there is a widespread shortage of selenium, thus producing selenium-rich agricultural products to provide natural selenium-rich health food to the areas in need of selenium, has gradually become a new hot spot of China’s health food industry, but high content of selenium in food is detrimental to human body, even leads to selenium intoxication, and artificially adding inorganic selenium is difficult to guarantee that the selenium content of agricultural products is not exceeded. According to human body’s daily demand for selenium in dietetics and the content of selenium in agricultural products in the Chinese food composition table, we put forward the recommendations on the standard of selenium in agricultural products, in order to provide the basis for China to formulate the health standard of selenium content in selenium-rich agricultural products.

  19. Microbiological Production of Surfactant from Agricultural Residuals for IOR Application

    2002-04-01

    Utilization of surfactants for improved oil recovery (IOR) is an accepted technique with high potential. However, technology application is frequently limited by cost. Biosurfactants (surface-active molecules produced by microorganisms) are not widely utilized in the petroleum industry due to high production costs associated with use of expensive substrates and inefficient product recovery methods. The economics of biosurfactant production could be significantly impacted through use of media optimization and application of inexpensive carbon substrates such as agricultural process residuals. Utilization of biosurfactants produced from agricultural residuals may 1) result in an economic advantage for surfactant production and technology application, and 2) convert a substantial agricultural waste stream to a value-added product for IOR. A biosurfactant with high potential for use is surfactin, a lipopeptide biosurfactant, produced by Bacillus subtilis. Reported here is the production and potential IOR utilization of surfactin produced by Bacillus subtilis (American Type Culture Collection (ATCC) 21332) from starch-based media. Production of surfactants from microbiological growth media based on simple sugars, chemically pure starch medium, simulated liquid and solid potato-process effluent media, a commercially prepared potato starch in mineral salts, and process effluent from a potato processor is discussed. Additionally, the effect of chemical and physical pretreatments on starchy feedstocks is discussed.

    The combination of degrading natural conditions and resources, climate change, growing population, urban development, and competition in a global market complicate optimization of land for agricultural products. The use of pesticides and fertilizers for crop production in the agricultural fields has become excessive in the recent years and Golestan Province of Iran is no exception in this regard. For this, effective management with an efficient and cost-effective practice should be undertaken, maintaining public service at a high level and preserving the environment. Improving the production efficiency of agriculture, efficient use of water resources, decreasing the use of pesticides and fertilizers, improving farmer revenue, and conservation of natural resources are the main objectives of the allocation, ranking, and optimization of agricultural products. The goal of this paper is to use an optimization procedure to lower the negative effects of agriculture while maintaining a high production rate, which is currently a gap in the study area. We collected information about fertilizer and pesticide consumption and other data in croplands of eastern Golestan Province through face-to-face interviews with farmers to optimize cultivation of the agricultural products. The toxicity of pesticides according to LD50 was also included in the optimization model. A decision-support software system called multiple criteria analysis tool was used to simultaneously minimize consumption of water, chemical fertilizers, and pesticides and maximize socio-economic returns. Three scenarios for optimization of agricultural products were generated that alternatively emphasized on environmental and socio-economic goals. Comparing socio-economic and environmental performance of the optimized agricultural products under the three scenarios illustrated the conflict between social, economic, and environmental objectives. Of the six crops studied (wheat, barley, rice, soybeans, oilseed rape

    Full Text Available Agriculture is one of the economic sectors that affect climate change contributing to greenhouse gas emissions directly and indirectly. There is a trend of agricultural greenhouse gas emissions reduction, but any practice in this direction should not affect negatively farm productivity and economics because this would limit its implementation, due to the high global food and feed demand and the competitive environment in this sector. Precision agriculture practices using high-tech equipment has the ability to reduce agricultural inputs by site-specific applications, as it better target inputs to spatial and temporal needs of the fields, which can result in lower greenhouse gas emissions. Precision agriculture can also have a positive impact on farm productivity and economics, as it provides higher or equal yields with lower production cost than conventional practices. In this work, precision agriculture technologies that have the potential to mitigate greenhouse gas emissions are presented providing a short description of the technology and the impacts that have been reported in literature on greenhouse gases reduction and the associated impacts on farm productivity and economics. The technologies presented span all agricultural practices, including variable rate sowing/planting, fertilizing, spraying, weeding and irrigation.

    Salinity pollution can have many negative impacts on water resources used for drinking, irrigation, and industrial purposes. Elevated concentrations of salinity in irrigation water can lead to decreased crop production or crop death and, thus, causing an economic problem. Overall, salinity pollution is a global problem but tends to be more severe in arid and semi-arid regions where the dilution capacity of rivers and lakes is lower and the use of irrigation higher. Particularly in these regions agricultural production is exposed to high salinity of irrigation water as insufficient water quality further reduces the available freshwater resources. According to the FAO, irrigated agriculture contributes about 40 percent of the total food production globally, and therefore, high salinity pollution poses a major concern for food production and food security. We use the WaterGAP3 modeling framework to simulate hydrological, water use, and water quality conditions on a global scale for the time period 1990 to 2010. The modeling framework is applied to simulate total dissolved solids (TDS) loadings and in-stream concentrations from different point and diffuse sources to get an insight on potential environmental impacts as well as risks to agricultural food production. The model was tested and calibrated against observed data from GEMStat and literature sources. Although global in scope, the focus of this study is on developing countries, i.e., in Africa, Asia, and Latin America, as these are most threatened by salinity pollution. Furthermore, insufficient water quality for irrigation and therefore restrictions in irrigation water use are examined, indicating limitations to crop production. Our results show that elevated salinity concentrations in surface waters mainly occur in peak irrigation regions as irrigated agriculture is not only the most relevant water use sector contributing to water abstractions, but also the dominant source of salinity pollution. Additionally

  10. Energy production from agricultural residues: High methane yields in pilot-scale two-stage anaerobic digestion

    2008-01-01

    There is a large, unutilised energy potential in agricultural waste fractions. In this pilot-scale study, the efficiency of a simple two-stage anaerobic digestion process was investigated for stabilisation and biomethanation of solid potato waste and sugar beet leaves, both separately and in co-digestion. A good phase separation between hydrolysis/acidification and methanogenesis was achieved, as indicated by the high carbon dioxide production, high volatile fatty acid concentration and low pH in the acidogenic reactors. Digestion of the individual substrates gave gross energy yields of 2.1-3.4 kWh/kg VS in the form of methane. Co-digestion, however, gave up to 60% higher methane yield, indicating that co-digestion resulted in improved methane production due to the positive synergism established in the digestion liquor. The integrity of the methane filters (MFs) was maintained throughout the period of operation, producing biogas with 60-78% methane content. A stable effluent pH showed that the methanogenic reactors had good ability to withstand the variations in load and volatile fatty acid concentrations that occurred in the two-stage process. The results of this pilot-scale study show that the two-stage anaerobic digestion system is suitable for effective conversion of semi-solid agricultural residues as potato waste and sugar beet leaves

  11. Women and agricultural productivity: Reframing the Issues.

    Science.gov (United States)

    Doss, Cheryl R

    2018-01-01

    Should agricultural development programmes target women in order to increase productivity? This article analyzes the challenges in distinguishing women's agricultural productivity from that of men. Most of the literature compares productivity on plots managed by women with those managed by men, ignoring the majority of agricultural households in which men and women are both involved in management and production. The empirical studies which have been carried out provide scant evidence for where the returns to projects may be highest, in terms of who to target. Yet, programmes that do not consider gendered responsibilities, resources and constraints, are unlikely to succeed, either in terms of increasing productivity or benefitting men and women smallholder farmers.

    Quality evaluation of agricultural products has been interested to many researchers for many years and as the result, several nondestructive techniques and so many papers have been reported for quality evaluation of agricultural products. These nondestructive techniques are based on the detection of mechanical, optical, electrical, electro-magnetical, dielectric and vibrational properties of agricultural products that are well correlated with certain quality factors of the products such as color, shape, firmness, sugar content, external or internal defects, moisture content, etc. The sophistication of nondestructive methods has evolved rapidly with modem technologies. In this paper an emphasis was put on reviewing some of those papers and techniques which could be led to on-line measurement for practical use.

    Pakistan is an agricultural developing country. About 68% of the country's population resides in rural areas and is mostly linked with agriculture. Agricultural sector contributes more than 25% to GDP, employees about 45% of the labour force and contributes significantly to export earnings of the country. Energy sector is the major source (80%) of emissions of Greenhouse Gases (GHGs). Agriculture and livestock sectors are also responsible for GHGs emissions. The emissions of GHGs results in acid rain and earth's temperature rise (global warming). The destabilization of the global climate destroys natural ecosystem and increases natural disasters, such as violent storms, floods, droughts etc. The acid rain and these natural disasters affect the agricultural productivity. The study indicates that the agricultural productivity per capita in Pakistan decreased continuously during the last two decades. The paper concludes that due to emissions of GHGs, the agricultural productivity is significantly affected in the country. The government should take concrete measures to minimize the emissions of GHGs for increasing the agricultural productivity and reducing other harmful impacts in the country. This paper presents the review and analysis of the effects of GHGs emissions on the agricultural productivity in Pakistan. (author)

    Agriculture is one of the main causes of biodiversity loss. In this work we model the interdependent relationship between biodiversity and agriculture on a farmed land, supposing that, while agriculture has a negative impact on biodiversity, the latter can increase agricultural production. Farmers act as myopic agents, who maximize their instantaneous profit without considering the negative effects of their practice on the evolution of biodiversity. We find that a tax on inputs can have a pos...

    Full Text Available Based on World Health Organization (WHO report, our society’s health ranks 123 among 192 countries. Unfortunately, this ranking position is very low and its main reason is malnutrition due to imbalanced fertilization. Although more than 85% of Iranian people are not hungry, about 90% of them are suffering from cell hunger, because agricultural authorities and hence producers do not pay attention to food security. According to the latest information, about 86.5% of applied fertilizers in our country appertain to urea and triple super phosphate. In fact, this is an alarming issue in respect to the production of healthy agricultural products and it remains a threat to food security. At present, a total subsidy of more than 7,000 billion rials is paid for nitrogen (N and phosphate (P fertilizers. Whereas, it should be considered that, firstly, the efficiency of these fertilizers, due to different reasons such as mismanagement and existing subsidy level, is low and, secondly, the overuse of these fertilizers causes the accumulation of nitrate (NO3 and cadmium (Cd in agricultural products. Furthermore, according to the law of minimum, the overdosed fertilizers do not have any special positive effect on sustainable production and society’s health. Paying for such high-cost subsidy just for N and P-fertilizers has caused farmers to overuse and waste these fertilizers in the country and moreover not having any tendency to apply biologic, organic and micronutrient fertilizers. Whereas, the application of these fertilizers, beside their adaptability with the environment, has a very positive effect on the human health. Therefore, at this time scientific management of production and application of all kinds of fertilizers is inevitable. In this case, by improving the quality of all types of fertilizers, and following the principle of balanced fertilization, besides achieving the desired yield increase, the quality of agricultural products will be

    The final food and environmental safety assessment of agriculture product irradiation can only be determined by product history. Product history will be used for future research and development, regulations, commercial practices and implementation of agriculture and food irradiation on a regional basis. The commercial irradiator treats large varieties and amounts of products that are used in various environments. it, in time, will generate a large data base of product history. Field product monitoring begins when food irradiation progresses from the pilot/demonstration phase to the commercial phase. At that time, it is important that there be in place a monitoring system to collect and analyze field data. The systems managers, public health authorities and exotic disease specialists will use this information to assess the reduction of food pathogens on the populace and the environment. (author)

    Full Text Available The current study is a review of characteristics, production, physiological properties and application of xylooligosaccharides (XOS. XOS are the carbohydrates, their molecules are built from xylose residues linked mainly by в-(1→4-glycoside bonds. Xylan is important for plant cell walls and is widely spread component in agricultural by-products. XOS are products of xylan hydrolytic degradation, and exhibiting the high prebiotic potential. The XOS preparation of wheat and rye bran stimulated the cells accumulation ‑ 1,4∙1010 CFU/cm3 of L. аcidophilus and 9,2∙1010 CFU/cm3 of В. bifidum. A difference in XOS molecules branching causes a wide range of their physiological properties: antioxidant, immunomodulation, antimicrobial, anti-inflammatory, anticarcinogenic. XOS can reduce high cholesterol level and triglycerides in blood plasma. XOS application reviewed in this article opens new perspectives on its potential use for human consumption. The rich sources of xylan are wheat, rye and barley bran, rice husk, wheat straw, corncobs, cotton stalk. Industrial way of XOS production includes chemical or enzymatic hydrolysis with following purification. Chemical methods are based on hydrothermal pretreatment and acidic or alkali extraction. Obtained oligosaccharides have a wide range of polymerization degree (DP from 2 to 20. Enzymatic methods include fermentation with xylanase that allow controlling the XOS accumulation with certain DP. The different chromatographic purification after hydrolysis is used for analytical purposes. There are anion-exchange, size-exclusion, affinity, size-exclusion high-performance liquid chromatography. In addition, biomethods are preferred for XOS used in food, because such preparations do not contain monosaccharides and furfural as contaminants. XOS are stable in a wide range of temperature and pH, justifying the development of new synbiotics generation. Most widely XOS are used in production of functional

    The public sector is an important source of agricultural research as the agricultural sector in many countries consists of a number of individual farmers who have difficulty in bearing the cost of research and development. Public institutes for testing and research called Kosetsushi help agriculture and manufacturing improve labor productivity through technology transfer activities, whereby constituting an important component of regional innovation systems in Japan. This study establishes panel data of agricultural Kosetsushi and examines whether their research activities are responsive to local needs and which type of research effort is conducive to the promotion of agricultural product innovations. Estimation results reveal variations across plants in the impacts of agricultural clusters on research on the plant conducted by Kosetsushi located in the cluster. A positive impact is observed only for vegetable while negative or statistically insignificant relationships are found for rice, fruit, and flower. The impact of research on plant breeding on agricultural product innovations also varies across plants. Policy implications of the major findings are discussed.

    There are many different perspectives about the sustainable agriculture, which had been proposed since the last three decades in the world. While China's ecologists and agronomists proposed a similar concept named 'ecological agriculture'. Although ecological agriculture in China has achieved substantial progress, including theory, models and supporting technologies nearly several decades of practice and development, its application guidance still is not yet clear. The organic agriculture model proposed by European Union is popular, but it is limited in the beneficiary groups and the social and ecological responsibility. In this context, the article based on an ecological point of view, analyzed the shortcomings of ecological imbalance caused by a single mode of agricultural production and the negative impact on the quality of agricultural products, and discussed the core values of ecological agriculture. On this basis, we put forward the concept of sustainable security of agricultural products. Based on this concept, an agricultural platform was established under the healthy ecosysphere environment, and from this agricultural platform, agricultural products could be safely and sustainably obtained. Around the central value of the concept, we designed the agricultural sustainable and security production model. Finally, we compared the responsibility, benefiting groups, agronomic practices selection and other aspects of sustainable agriculture with organic agriculture, and proved the advancement of sustainable agricultural model in agricultural production quality and safety.

    Full Text Available Deltas are highly sensitive to erosion, flooding, and salinization with consequential agricultural productivity losses and out-migration, which is a preferred adaptive measure for the inhabitants of deltaic islands. This study investigates the associations between agricultural productivity decrease, household poverty and the probability of out-migration in the Indian Sundarban Delta (ISD. Using newly collected survey data from randomly selected households within the ISD, we analysed these relationships by means of descriptive statistics and regression modeling. Results suggest the significant positive association between a decrease in agricultural productivity and out-migration. The results further show that ceteris paribus, out-migration is negatively associated with household poverty, which is likely to be explained by the effect of remittances. The results yield important policy implications at the local level and can contribute to the progress towards sustainable livelihoods in these deltaic islands.

    Energy production from biomasses can be an important resource that, when combined with other green energies such as wind power and solar plants, can contribute to reduce dependency on fossil fuels. The aim of this study is to assess how agriculture could contribute to the production of bio-energy. A multi-period Weighted Goal Programming model (MpWGP) has been applied to identify the optimal land use combinations that simultaneously maximise farmers' income and biomass energy production under three concurrent constraints: water, labour and soil availability. Alternative scenarios are considered that take into account the effect of climate change and social change. The MpWGP model was tested with data from the Rovigo county area (Italy) over a 15-year time period. Our findings show that trade-off exists between the two optimisation targets considered. Although the optimisation of the first target requires traditional agricultural crops, which are characterised by high revenue and a low production of biomass energy, the latter would be achievable with intensive wood production, namely, high-energy production and low income. Our results also show the importance of the constraints imposed, particularly water availability; water scarcity has an overall negative effect and specifically affects the level of energy production. - Research Highlights: → The aim of this study is to assess how agriculture could contribute to the production of bio-energy. → A multi-period (15-year) Weighted Goal Programming model (MpWGP) has been applied. → We identify the optimal land use combinations that simultaneously maximise farmers' income and biomass energy production. → Three concurrent constraints have been considered: water, labour and soil availability.→ Water scarcity has an overall negative effect and specifically affects the level of energy production.

    Full Text Available Effective management of agricultural production in the Polesie Ukraine traditionally was complicated through the low natural land fertility, their high acidity, perevolotsky valley. During the centrally planned economic system that the natural contrast of the Polesie land had been somewhat neglected by the state through differentiation of purchase prices for agricultural products, which gave the possibility of redistribution of the rent in favor of the farms with poorer land. With transition to market relations the role of the state, and hence the possibility of its influence on this situation has changed dramatically. Economic conditions have become more profitable for the farmers that are occupying the best lands. However, the situation in the regions has not yet been investigated systematically taking into account the modern complex socio-economic processes and phenomena caused by increased environmental stress on land resources. One of the most pernicious environmental effects of the Chernobyl accident was radioactive contamination of agricultural land, defined in the final stage of transfer of radionuclides in the human body and further irradiation. The main danger of the accumulation by plants of radionuclides lies in the fact that they are a major link in the migratory chain of transmission of radionuclides to the more radiosensitive species and, above all, human. Economic feature of agricultural production in the study area is insufficient pricesambien, transformation of land use, violations of industrial-economic relations, the structure of agricultural production, changes in the natural-cost structure commodity products, the reform of the organizational structure of agricultural production.

    Full Text Available Farm Accountancy Data Network (FADN was established in the EU in 1965 and now it is obligated for all member states of the EU. The system is based on an annual collection of production, economic and financial data from a representative sample of comercial farms, classified into groups according to the criteria of economic farm size, type of agricultural production and regional affiliation. Research made by FADN system represent the European Commission instrument for evaluating the income of agricultural producers and determining the impact of the Common Agricultural Policy of the EU on their business. In this paper the comparison is made between production and economic indicators of different types of agricultural holdings (field crops; horticulture crops; permanent crops, orchards and olive yards; dairy farms; grazing livestock; pig and poultry farms and mixed farms. On the basis of Standard Results for the year 2014 it is possible to conclude that in Croatia field crops and grazing livestock farms lead by their utilized agricultural area. Pig and poultry farming have the most livestock units, while the most working hours is spent in the cultivation of vegetables and flowers. The highest values of labor productivity have holdings that are engaged in the production of vegetables and flowers, while the lowest labor productivity have grazing livestock farms. Cost-effectiveness of all types of farms exceeding a value of 1. The highest value of the gross income is achieved at pig and poultry farms, while the smallest has a mixed type of farms. The average farm direct payments account for a high 44% in the net income, and the largest share of direct payments in the net income has field crop type of farms.

    With an increasing and increasingly affluent population, humans will need to roughly double agricultural production by 2050. Continued yield growth forms the foundation of all future strategies aiming to increase agricultural production while slowing or eliminating cropland expansion. However, a recent analysis by one of our co-authors has shown that yield trends in many important maize, wheat and rice growing regions have begun stagnating or declining from the highs seen during the green revolution (Ray et al. 2013). Additional research by our group has shown that nearly 50% of new agricultural production since the 1960s has gone not to direct human consumption, but instead to animal feed and other industrial uses. Our analysis for GLP looks at the convergence of these two trends by examining time series utilization data for 16 of the biggest crops to determine how demand from different sectors has shaped our land-use and intensification strategies around the world. Before rushing headlong into the next agricultural doubling, it would be prudent to first consult our recent agricultural history to better understand what was driving past changes in production. Using newly developed time series dataset - a fusion of cropland maps with historic agricultural census data gathered from around the world - we can examine yield and harvested area trends over the last half century for 16 top crops. We combine this data with utilization rates from the FAO Food Balance Sheet to see how demand from different sectors - food, feed, and other - has influenced long-term growth trends from the green revolution forward. We will show how intensification trends over time and across regions have grown or contracted depending on what is driving the change in production capacity.

    Full Text Available Today, finding data on agricultural nitrogen balances is quite easy. Calculations of such balances are carried out by most of the European countries as an indicator of environmental pollution attributable to the agricultural sector. In France, average values of agricultural nitrogen balances show an excess of 1.5 to 2 million tons of nitrogen. This excess is enormous. What would the balance of a country be if agricultural activity were stopped? In the following article, a country (France is used as an example without agriculture is studied in order to assess its nitrogen balance. Using a previously published model describing nitrogen input and output of a given country, nitrogen flows are identified. Inputs include deposition, fixation, and products not intended for agricultural use. Outputs are reduced to zero if agriculture disappears (in France, agriculture is the only sector exporting products containing nitrogen. All flows are calculated considering the hypothesis of disappearance of agriculture. Nitrogen requirements to feed people and pets in France are estimated based on medical and veterinary data (recommended daily amounts for proteins and/or usual average consumption. Indeed, most of the food that nourishes the French population is produced nationally. If agriculture stops, it will be necessary to import food from foreign countries. Results show an unexpectedly high excess (for a country without agriculture having a structure similar to France: number of human beings and pets of 1.5 million tons of nitrogen. An attempt to calculate an agricultural balance with the same data gives a result close to 3 million tons. Differences in French agricultural balances found in the literature can mainly be explained by values taken into account for deposition and fixation (values used here are at least 300,000 tons higher than values used by the Organisation for Economic Co-operation and Development. In conclusion, nitrogen excess in agriculture

It was found that agricultural biogas plant in rural areas are an important link in energy security, mainly due to the very high availability. Ecological effect is presented as effect of the installation solutions for the reduction of pollution of water, soil and air. Reducing greenhouse gas emissions through the recycling of environmentally harmful by-products of animal production of electricity and thermal energy, which is a substitute for environmentally harmful fossil fuels. The advantage of substances digestate is odorless, which is important both in an effort to improve the work culture in agriculture and improving living conditions in rural communities and it is an indisputable argument for the use of biomass for energy purposes.

  5. Radio-Agriculture - Ground and Space-Based Determination of Agricultural Productivity

    Science.gov (United States)

    Cockell, C. S.

    The decision to sow seeds in a field, either on a local level (such as on an individual plot) or on vast agricultural complexes, is irreversible. Once the seed is sown, provided there is liquid water, tem- perature conditions are adequate and in some cases light is available, it will germinate. The timing of seed sowing has important effects on subsequent agricultural productivity [1-4]. The correlation between time of sowing and productivity causes several problems. Firstly, sowing seed depends absolutely upon a correct judgement on weather conditions, sometimes to the day. Secondly, not all crops need to be sown at the same time and so resources in manpower and equipment must be available for sowing different crops at different times. Great im- provements in resource allocation could be made if all seeds could be sown at the same time. Thirdly, there is no flexibility once resources to sowing have been committed. For example, in large agricultural areas manpower and machinery might be committed at particular times of the year to sowing, but if the weather conditions are not correct either they must be re-scheduled or productivity is lost. Local factors such as irrigation system availability might also impose upon a farmer a wish to be able to regulate the germination of particular fields, particularly in developing countries.

    Full Text Available The transportation infrastructure plays a significant role in the development of agriculture. In this study we examine the relationship between transport and agricultural performance by employing the World Bank’s roads infrastructure indicators. Based on a cross-country sample, a classic method is employed to test the hypothesis that better transport fosters agricultural productivity. The empirical results of the method support the hypothesis. As for this method, the estimation results of the widely-used inter-country aggregate agricultural production function describe that a country with better transport can produce more agricultural outputs given the same amounts of agricultural inputs and the same education level. Our empirical work lends support to the claim of Gollin and Rogerson (2010 [19] that transport is a basic factor explaining the poor economic performance of many developing countries, apart from physical and education investments, more emphasis should be placed on improving the transport infrastructure of these countries.

    Increasing rice productivity will continue to be an important agenda in the agricultural development program of the country. This represents a challenge to the Department of Agriculture. To address this challenge, it calls for creativity, innovation, ideas and initiatives in the use of technologies that consist of land leveling, in the field water management, Integrated Pest Management (IPM), production and distribution of quality seeds, effective fertilizer usage and value added activities. Rice areas which have been leveled using laser guided technology have shown yield increase from 3.3 t/ha to 5.1 t/ha. In-field water management increases rice yield, reduces water wastage and ensures timeliness of operations and improve soil water bearing capacity. IPM has proven highly beneficial in the control of field rats, reducing the incidence of diseases such as rice blast, lowering the occurrence of insect pest outbreaks and weed infestation. Fish rearing and fattening of ducklings to adulthood in the rice fields have also been undertaken as profitable enterprises in the rice farming system. In its effort to modernise and increase rice productivity, the Department of Agriculture approach in acquisition of technology from research agencies, and its adaptation and adoption are discussed. Any technology promoted must be economically viable, socially acceptable and technologically feasible for effective implementation. (Author)

    Agricultural and food processing industries are always looking to implement real-time quality monitoring techniques as a part of good manufacturing practices (GMPs) to ensure high-quality and safety of their products. Near-infrared (NIR) hyperspectral imaging is gaining popularity as a powerful non-destructive tool for quality analysis of several agricultural and food products. This technique has the ability to analyse spectral data in a spatially resolved manner (i.e., each pixel in the image has its own spectrum) by applying both conventional image processing and chemometric tools used in spectral analyses. Hyperspectral imaging technique has demonstrated potential in detecting defects and contaminants in meats, fruits, cereals, and processed food products. This paper discusses the methodology of hyperspectral imaging in terms of hardware, software, calibration, data acquisition and compression, and development of prediction and classification algorithms and it presents a thorough review of the current applications of hyperspectral imaging in the analyses of agricultural and food products.

    The Agricultural Research Service (ARS) is the in-house research arm of the U.S. Department of Agriculture (USDA). The research program bias is toward crop production, the historical focus of agricultural research. There is, however, an existing realization that, in order to maintain and strengthen the competitiveness of the United States in global agriculture, new uses must be found, developed, and commercialized for raw bulk agricultural commodities such as maize (corn), soybeans, and wheat. Biofuels such as ethanol from cornstarch, and biodiesel from soybean oil are being promoted strongly as a way of utilizing agricultural commodities more profitably to the farmer. Over the years, ARS has maintained a bioenergy program which has had fluctuating support, and thus a variation in dimensions. At present, there is strong political and departmental backing; in fact there is a fruitful collaboration being developed between the USDA and the U.S. Department of Energy through a Memorandum of Understanding. Ethanol from starch and other less tractable forms of biomass have been subjected to a barrage of economic evaluations, not exactly overoptimistic. In these studies, the large contribution by feedstock cost to the overall cost of production is pointed out. This has led to research programs on biomass production and also attempts at lowering costs of ethanol production by improved pretreatment, conversion, and product recovery. Progress toward lowering production costs has been undeniable, but slow

    Full Text Available Agricultural and food products are a significant segment of the total foreign trade of Serbia, which is characterized by a relatively high import dependency, modest export and constantly present deficit. In such conditions, agrarian sector serves as a stabilizer, and its importance is reflected in the permanently positive balance, increased participation, particularly in total exports, and balancing the trade balance of the country. The aim of the paper is to analyze the basic characteristics of foreign trade of agricultural and food products of Serbia in the period 2005-2015. The tendencies in export, import, and the level of coverage of import by export of agro-food (or agrarian products are analysed. The participation of these products in the total foreign trade of Serbia is also considered, followed by the comparison of this indicator with the neighbouring countries. In the next part of the paper, the structure of Serbian export and import of agricultural and food products (by product groups is analysed. Special attention is given to the territorial orientation of export and import of agrarian products by the most important trade partners. In order to conduct more comprehensive analysis of comparative advantages, or competitiveness of certain groups of agro-food products of Serbia in the exchange with the world, indicator of Revealed Comparative Advantage (RCA is calculated. The analysis of qualitative competitiveness is derived using the indicator - unit value of export and import. The analysis points to the dynamic growth in the value of Serbian export and import of agro-food products, with the constant surplus of trade balance in the observed period. These products are significantly represented in the structure of the total foreign trade of the country, particularly in export (with about 20%. RCA indicators show that Serbia has a comparative advantage in trade of agro-food products to the world in primary products and products of lower

    Global agricultural feeds over 7 billion people, but is also a leading cause of environmental degradation. Understanding how alternative agricultural production systems, agricultural input efficiency, and food choice drive environmental degradation is necessary for reducing agriculture’s environmental impacts. A meta-analysis of life cycle assessments that includes 742 agricultural systems and over 90 unique foods produced primarily in high-input systems shows that, per unit of food, organic systems require more land, cause more eutrophication, use less energy, but emit similar greenhouse gas emissions (GHGs) as conventional systems; that grass-fed beef requires more land and emits similar GHG emissions as grain-feed beef; and that low-input aquaculture and non-trawling fisheries have much lower GHG emissions than trawling fisheries. In addition, our analyses show that increasing agricultural input efficiency (the amount of food produced per input of fertilizer or feed) would have environmental benefits for both crop and livestock systems. Further, for all environmental indicators and nutritional units examined, plant-based foods have the lowest environmental impacts; eggs, dairy, pork, poultry, non-trawling fisheries, and non-recirculating aquaculture have intermediate impacts; and ruminant meat has impacts ∼100 times those of plant-based foods. Our analyses show that dietary shifts towards low-impact foods and increases in agricultural input use efficiency would offer larger environmental benefits than would switches from conventional agricultural systems to alternatives such as organic agriculture or grass-fed beef.

  18. Policies for reduced deforestation and their impact on agricultural production.

    Angelsen, Arild

    2010-11-16

    Policies to effectively reduce deforestation are discussed within a land rent (von Thünen) framework. The first set of policies attempts to reduce the rent of extensive agriculture, either by neglecting extension, marketing, and infrastructure, generating alternative income opportunities, stimulating intensive agricultural production or by reforming land tenure. The second set aims to increase either extractive or protective forest rent and--more importantly--create institutions (community forest management) or markets (payment for environmental services) that enable land users to capture a larger share of the protective forest rent. The third set aims to limit forest conversion directly by establishing protected areas. Many of these policy options present local win-lose scenarios between forest conservation and agricultural production. Local yield increases tend to stimulate agricultural encroachment, contrary to the logic of the global food equation that suggests yield increases take pressure off forests. At national and global scales, however, policy makers are presented with a more pleasant scenario. Agricultural production in developing countries has increased by 3.3-3.4% annually over the last 2 decades, whereas gross deforestation has increased agricultural area by only 0.3%, suggesting a minor role of forest conversion in overall agricultural production. A spatial delinking of remaining forests and intensive production areas should also help reconcile conservation and production goals in the future.

    The quality and safety of agricultural products is not only a major livelihood issues for people’s health, but also the main barriers to international trade of agricultural products nowadays. The soil is the foundation to the production of agricultural products and the guarantee of agricultural development. The farmland soil quality is directly related to the quality and safety of agricultural products. Our country’s soil has been polluted by a series of pollution, Such as the excessive discharge of industrial wastes, the encroachment of household waste, and the unreasonable use of pesticides and fertilizers. Soil degradation is a serious threat to the quality and safety of agricultural products, so eliminating soil degradation is the fundamental way out for quality and safety of agricultural products. By analyzing problems of the quality and safety of agricultural products in our country, and exploring the farmland soil influence on the quality and safety of agricultural products. This article provides a reference for improving the control level of quality and safety of agricultural products and the farmland soil quality.

    Full Text Available The paper introduces a research on the changes occurred inside the accounting system of agricultural organisations in the transitional period. Changes of structure and accounting information system being results of privatisation processes were analysed. The introduction of modern methods in the preparation of relevant management information represents one of the preconditions for development of the privatised agricultural organisation during the transition period. Information prepared by the accounting, especially adapted to management requirements, is essential for rational decision making. Modern management system of reporting is fundamental task of management and a precondition for securing competitive production in agricultural industry. For this reason, it is necessary to define areas of responsibility and to enable application of a modern techniques for calculating expenses. The purpose of this paper is to emphasise the specialised use of accounting information by managers and to develop methods of management reporting in agricultural organisations. We propose an emphasis upon the application of modern management accounting techniques rather than financial accounting reporting approach. We support the contention that the need for high-quality management accounting is not debatable and tend to explain how and why accounting information is developed for the individual parts of a business entity, that is for each department or enterprise of an agricultural organisation. The responsibility accounting system should be introduced in agricultural business entities within our conditions, especially in larger organisations, as a measure of securing competitive production. We emphasise the importance of distinguishing between direct and indirect expenses and of using appropriate methods to allocate expenses among departments or enterprises. The research is based on information directly received from the largest agricultural companies in the area of

    Full Text Available China has recorded positive growth rates of grain production for the past eleven consecutive years. This is a remarkable accomplishment given that China's rapid industrialization and urbanization has led to a vast reduction of arable land and agricultural labor to non-agricultural sectors. While there are many factors contributing to this happy outcome, one potential contributing factor that has received increasing attention is the emergence of agricultural production outsourcing, a new rural institution that has emerged in recent years. This study aims to contribute to the limited but growing literature on agricultural production outsourcing in China. Specifically, this study analyzes factors affecting farmers' decisions to outsource any or some production tasks using data from rice farmers in Zhejiang province. Results from a logistic model show that farm size and government subsidy encourages farmers to outsource while ownership of agricultural machines and land fragmentation have negative effects on farmers' decisions to outsource production tasks. Results also showed that determinants of outsourcing decisions vary with the production tasks that farmers outsourced.

    Full Text Available Sustainability of agricultural production in the world is in serious crisis. Interdependence of agricultural production and the environment is multiple and causality works both ways. On one hand, there are environmental changes which hamper food production, and on the other, the agricultural production, as it is, is severely damaging the environment. The very systems of agricultural production jeopardize future production. The goal of this paper is to explore causes of limitations of sustainable agricultural development in the world, where the authors emphasize the following: gas emissions with greenhouse effect, a disturbed cycle of nitrogen circulation and destruction of biodiversity.

    2017-09-01

    Full Text Available The aim of the article is to study the conceptual provisions of the essence of labour productivity in agriculture in order to determine the factors and conditions for its growth at the present stage of economic development. Methods. The theoretical and methodological bases of research are the works of classical and modern economic science concerning labour productivity and human capital. With the aim of concretizing the conceptual and categorical apparatus, the dialectical and abstract-logical methods were used; a monographic method was used during covering the views of scientists on the investigated problem; for the analysis of labour productivity trends, the method of comparative analysis and the graphical method were used. Results. The conditions of agricultural production management in an agrarian region are characterized. Factors of labour productivity growth in agriculture are determined. It is established that the main reserves of increasing labour productivity consist of reducing labour costs for the production of agricultural products. In turn, the reduction of labour costs is caused by the use of new equipment and new technologies, progressive forms of labour organization, improvement of the system of material incentives for labour. Practical significance. The realization of proposals and recommendations concerning the formation and development of human capital for agricultural production, optimization of production resources, strengthening of labour motivation will provide an opportunity to increase the labour activity of personnel, the volume of agricultural production. Relevance/originality. Further development of research results allows us to collect an empirical, multifactorial model of labour productivity growth in agricultural production.

    2013-10-01

    Full Text Available This paper summarises the simulated effects on Finnish agricultural production and trade of a 20% decrease in Finnish demand for red meat (beef, pork, lamb. According to our results, reduced red meat consumption would be offset by increased consumption of poultry meat, eggs, dairy products and fish, as well as small increases in consumption of fruits and vegetables, peas, nuts, cereal products and sweets. By including the derived demand changes in an agricultural sector model, we show that livestock production in Finland, incentivised by national production-linked payments for milk and bovine animals, would decrease by much less than 20% due to the complex nature of agricultural production and trade. Overall, assuming unchanged consumer preferences and agricultural policy, a 20% reduction in red meat consumption is not likely to lead to a substantial decrease in livestock production or changed land use, or greenhouse gas emissions, from Finnish agriculture.

    While for wind, solar energy or hydropower, energy supply happens directly from the source to the wind wheels, hydropower turbines or solar panels, in the case of biogas, energy production cannot directly take from the energy source, organic matter, but depends on the institutional structures and farmers′ practices involved for making energy available. With the production of bioenergy in rural areas, practices within agriculture are transformed, requiring new ways of organizing production processes. Research has left the question largely unanswered of how agricultural biogas production and use are – and can best be – organized within rural society. Which kinds of social organization exist, how are these embedded in existing agricultural institutions and practices, and how do these systems function? Under which conditions may the different kinds of social organization of biogas production and use work sustainably? This introduction article to the Special Issue “The social organization of agricultural biogas production and use” presents a framework for analysing the different kinds of social organization of biogas production and use presented hereafter. Analysis parameters are the supply network, distribution network, distribution of benefits, social boundaries of the system (accessibility) and scale. Using these parameters, the Special Issue articles are outlined. - Highlights: • Through agricultural institutions and farmers′ practices, biogas is made available. • Scale, supply and delivery network distinguish biogas infrastructural systems. • Access and benefit distribution are key for a biogas system′s sustainability

    Full Text Available Innovative infrastructure of agrarian production in Lviv Area and basic problems of its development are investigated. On the basis of the conducted cluster analysis in the article six optimum areas are offered clusterizations of agricultural production, which are certain after the criterion of balanced cluster educations. The first area of clusterization is most suitable for development of plant-grower. In particular, in four its districts, almost fourth part of plant-grower products is concentrated in the permanent costs of 2010 year. The second area of clusterization can be identified as mainly stock-raising, as its localization in the districts of foot-hill of area creates favourable terms for the production of meat and milk goods. The third area can be attributed to balanced stock-raising-plant-grower straight, with development of agriculture, oriented to the sale of products to the cities, above all things in Lviv. The fourth area of clusterization can be considered mainly plant-grower-oriented with simultaneous development of the suckling cattle breeding. The fifth area of clusterization, as marked already, can be identified as innovative oriented with predominance of stock-raising and production of goods on an export. A sixth (mountain area of clusterization is the least suitable for development of agriculture (except for the milk and meat cattle breeding. The applied approach is based on the account of ten key indexes which characterize potential of agricultural production development in each districts of Lviv Area: products of plant-grower are in all categories of economic agents; products of stock-raising are in all categories of economic agents; area of agricultural lands which are engaged in an agricultural production area of plough-land of economic agents which are engaged in an agricultural production; sowing areas are in all categories of economic agents; a quantity of cattle is in all categories of economic agents; a quantity of

Labor productivity in agriculture was analyzed by two parameters, namely: the value of agricultural production and the number of employees in agriculture for the period 2011 – 2012. The level of labor productivity is influenced by the quality of biological and bio-capacity of plants and animals as well, as well as the equipment and quality of work performed. From the factorial analysis it can be noticed a decrease of labor productivity caused by a decrease in the value of agricultural production.

    Agricultural activities are large contributors to anthropogenic greenhouse gas emissions. This paper discussed the effectiveness of reducing agricultural emissions by using liquid manure to produce biogas. When using this technique, greenhouse gas emissions from manure storage are avoided and renewable energy is generated as heat and electricity in combined heat and power plants. The purpose of this study was to evaluate the environmental impacts of biogas production systems based on the methods of life cycle assessment. The traditional use of agricultural manures was compared with conventional energy production. The Gabi 4.3 software was used to create a model to evaluate the biogas production systems according to their environmental impact. In addition to the global warming potential, other impact categories were also used to evaluate the effects of the systems in eutrophication and acidification. It was concluded that environmental benefits can be obtained in terms of greenhouse gas emissions compared to electricity production from biogas with the typical German marginal electricity mix.

    The concept of sustainable development has evolved from a mere perception for the protection of the environment, to a holistic approach, seeking to preserve not only the environment, but also to achieve sustainability in economics and social wellbeing. Globally, there is a major challenge to face in the agricultural sector: to produce more food, feed and other raw materials to satisfy the increasing demand of a growing population, whilst also contributing to economic prosperity, climate change mitigation / adaptation, social wellbeing and preserving natural capital such as soil, water, biodiversity and other ecosystem services. Nowadays, conventional approaches to agriculture are under threat. A more productive and resource efficient agriculture that integrates natural resource protection into its approach will help to meet all these challenges, enabling us to have more of everything - more food, more feed, more non-food crops, more biodiversity and natural habitats - while also reducing greenhouse gas emissions. In this context, INSPIA is an innovative approach that has worked since 2013 towards demonstration that sustainable productive agriculture is possible thanks to the implementation of a host of best management practices (BMPs) capable of delivering the above achievements. The purpose on INSPIA is to make visible with European decision makers that a sustainable and productive agricultural model exists in a small scale in Europe and that wider dissemination is possible with enabling legislation. INSPIA is demonstrating sustainable agriculture through the implementation of BMPs and the measurement and monitoring of a set of defined indicators (economic, social and environmental ones). INSPIA promotes sustainable practices that protect biodiversity, soils and water and contribute towards maintaining ecosystems services. This holistic sustainable system of productive agriculture is based on the combination of Conservation Agriculture (CA) and Integrated Pest

    2010-09-27

    The relationships between basic and applied agricultural R&D, developed and developing country R&D and between R&D, extension, technology and productivity growth are outlined. The declining growth rates of public R&D expenditures are related to output growth and crop yields, where growth rates have also fallen, especially in the developed countries. However, growth in output value per hectare has not declined in the developing countries and labour productivity growth has increased except in the EU. Total factor productivity has generally increased, however it is measured. The public sector share of R&D expenditures has fallen and there has been rapid concentration in the private sector, where six multinationals now dominate. These companies are accumulating intellectual property to an extent that the public and international institutions are disadvantaged. This represents a threat to the global commons in agricultural technology on which the green revolution has depended. Estimates of the increased R&D expenditures needed to feed 9 billion people by 2050 and how these should be targeted, especially by the Consultative Group on International Agricultural Research (CGIAR), show that the amounts are feasible and that targeting sub-Saharan Africa (SSA) and South Asia can best increase output growth and reduce poverty. Lack of income growth in SSA is seen as the most insoluble problem.

The analysis based on framework of the Institutional Change reveals that as a whole,the outsourcing system of agricultural production improves the welfare of society effectively. To some extents,it also can solve the problem of food security. The rural transferring labor-forces who realize the institutional change in the initial stage are is the first Action Group to gain the potential benefits. Local governments are a breakpoint of induced institutional change, which find potential benefits and then change the role of system changes. The central government is in dominant statue during the whole change. The outsourcing is a kind of improvement to the Family Contracted System, also an adaption to an imperfect Chinese rural social security. So the outsourcing has a positive meaning in the rural area.

    Hydrogen peroxide is commonly used in the food processing industry as a chlorine-free bleaching and sterilizing agent, but excessive amounts of residual hydrogen peroxide have led to cases of food poisoning. Here we describe the development of a novel nonenzymatic colorimetric method for the determination of residual hydrogen peroxide in foods and agricultural products. Nitrophenylboronic acids chemoselectively react with hydrogen peroxide under alkaline conditions to produce yellow nitrophenolates. Of the three nitrophenylboronic acid isomers tested, the p-isomer displayed the highest sensitivity for hydrogen peroxide and the fastest reaction kinetics. The reaction product, p-nitrophenolate, has an absorption maximum at 405 nm and a good linear correlation between the hydrogen peroxide concentration and the A(405) values was obtained. We successfully applied this convenient and rapid method for hydrogen peroxide determination to samples of dried bean curds and disposable chopsticks, thereby demonstrating its potential in foods and agricultural industries.

    Organic agriculture has developed rapidly in China since the 1990s, driven by the increasing domestic and international demand for organic products. Quantification of the environmental benefits and production performances of organic agriculture on a national scale helps to develop sustainable high yielding agricultural production systems with minimum impacts on the environment. Data of organic production for 2013 were obtained from a national survey organized by the Certification and Accreditation Administration of China. Farming performance and environmental impact indicators were screened and indicator values were defined based on an intensive literature review and were validated by national statistics. The economic (monetary) values of farming inputs, crop production and individual environmental benefits were then quantified and integrated to compare the overall performances of organic vs. conventional agriculture. In 2013, organically managed farmland accounted for approximately 0.97% of national arable land, covering 1.158 million ha. If organic crop yields were assumed to be 10%-15% lower than conventional yields, the environmental benefits of organic agriculture (i.e., a decrease in nitrate leaching, an increase in farmland biodiversity, an increase in carbon sequestration and a decrease in greenhouse gas emissions) were valued at 1921 million RMB (320.2 million USD), or 1659 RMB (276.5 USD) per ha. By reducing the farming inputs, the costs saved was 3110 million RMB (518.3 million USD), or 2686 RMB (447.7 USD) per ha. The economic loss associated with the decrease in crop yields from organic agriculture was valued at 6115 million RMB (1019.2 million USD), or 5280 RMB (880 USD) per ha. Although they were likely underestimated because of the complex relationships among farming operations, ecosystems and humans, the production costs saved and environmental benefits of organic agriculture that were quantified in our study compensated substantially for the

    Full Text Available Introduction. Agriculture is one of the largest and most important sectors of the Ukrainian economy. The food security and independence of the state, the state of the internal and external markets, and, consequently, the standard of living of the population are directly dependent on its functional state. Mykolaiv region has significant opportunities for the development of the agricultural sector. There are favorable natural and climatic conditions, fertile land, labor resources and long-standing cultivating traditions. The region is considered one of the regions of intensive agriculture in Ukraine and has significant land resources. Purpose. The article presents the analysis of the development of production and sale of crop production by the agrarian enterprises of the Mykolaiv region, as well as revealing ways to increase the volume of their production and sales. Results. The crop area of main agricultural crops in all categories of farms was analyzed, and structural changes for 2010-2016 were revealed. The priority branch of the agro-industrial complex, which has an important strategic significance, first of all, is determined by the level of production of which the food security of the state depends, its economy and welfare of the population. The dynamics of agricultural crop yields in agrarian enterprises as the determining factor of influence on the efficiency of activity in the field of plant growing is researched. The dynamics of gross collections of crop production in agricultural enterprises is analyzed and the contribution of the Mykolaiv region to the national production of grain is determined. The volumes and average prices of sales of agricultural products by agrarian enterprises are investigated and it is determined that the modern development of the agrarian sector of the economy requires special attention to the formation and activation of the activities of market infrastructure entities. The production of which crops are an

    2014-10-01

    We adapt and integrate the Biome-BGC and Land Use in Rural New Zealand models to simulate pastoral agriculture and to make land-use change, intensification of agricultural activity and climate change scenario projections of New Zealand's pasture production at time slices centred on 2020, 2050 and 2100, with comparison to a present-day baseline. Biome-BGC model parameters are optimised for pasture production in both dairy and sheep/beef farm systems, representing a new application of the Biome-BGC model. Results show up to a 10% increase in New Zealand's national pasture production in 2020 under intensification and a 1-2% increase by 2050 from economic factors driving land-use change. Climate change scenarios using statistically downscaled global climate models (GCMs) from the IPCC Fourth Assessment Report also show national increases of 1-2% in 2050, with significant regional variations. Projected out to 2100, however, these scenarios are more sensitive to the type of pasture system and the severity of warming: dairy systems show an increase in production of 4% under mild change but a decline of 1% under a more extreme case, whereas sheep/beef production declines in both cases by 3 and 13%, respectively. Our results suggest that high-fertility systems such as dairying could be more resilient under future change, with dairy production increasing or only slightly declining in all of our scenarios. These are the first national-scale estimates using a model to evaluate the joint effects of climate change, CO2 fertilisation and N-cycle feedbacks on New Zealand's unique pastoral production systems that dominate the nation's agriculture and economy. Model results emphasise that CO2 fertilisation and N-cycle feedback effects are responsible for meaningful differences in agricultural systems. More broadly, we demonstrate that our model output enables analysis of decoupled land-use change scenarios: the Biome-BGC data products at a national or regional level can be re

    Enzymatic hydrolysis is the significant technique for the conversion of agricultural wastes into valuable products. Agroindustrial wastes such as rice bran, wheat bran, wheat straw, sugarcane bagasse, and corncob are cheapest and plentifully available natural carbon sources for the production of industrially important enzymes. Innumerable enzymes that have numerous applications in industrial processes for food, drug, textile, and dye use have been produced from different types of microorganisms from agricultural wastes. Utilization of agricultural wastes offers great potential for reducing the production cost and increasing the use of enzymes for industrial purposes. This chapter focuses on economic production of actinobacterial enzymes from agricultural wastes to make a better alternative for utilization of biomass generated in million tons as waste annually. © 2017 Elsevier Inc.

  5. Agricultural production as a source of irradiation of populations in radiation accidents

    International Nuclear Information System (INIS)

    Alexakhin, R.M.

    2000-01-01

    Radioactive contamination of the agricultural production sphere in case of a radiation accident with radionuclide release is one of the most important sources of additional irradiation for population. As a result, realisation of the measures for mitigating the consequences of the accident in agro-industrial complex assumes the leading role in total system of measures providing radiation safety. The possibility to obtain agricultural production meeting the radiological standards is one of the main indications of effectiveness of liquidation of the accident consequences. First, obtaining of agricultural production meeting the radiological standards provides decreasing of the total radiation dose. The evidence is obtained in the 8-year experience of liquidation of the Chernobyl NPP accident that the 70% decrease of the internal dose for population became possible through a complex of protection measures in agriculture (during the first year after the accident, the contribution of internal dose into the total one amounted to 45%, and that of external irradiation - 52%; for the 70-year period these values are 39% and 60%, respectively). Second, the possibility to obtain 'pure' agricultural production is one of the most important factors of psychological stability for population. Third, obtaining of consumable (as to radionuclide content) agricultural production in private small holdings is one of the guarantees of stability of demographic sector in the accident-affected zone. From the point of view of organization of agricultural production in liquidation of the consequences of accidents with radioactive releases into environment, some periods can be distinguished: (i) the first (early) period takes 10-12 days after the accident. The main measures in the field of agricultural production are in operative assessment of the radiological situation, organization of radiation survey, express classification of agricultural products ready to consumption. If radionuclide content

    Full Text Available Almost all countries in the world actively regulate both import and export of agricultural products, however this process is very conflictгфд because of acute contradictions on the market. They are associated with the changing conditions of production, increase of attention of the world community to the food securitysituation, change of the used resources efficiency level, competition enhancement. Both internal and external components of agricultural producers support are important for Russia. That means the regulation should be aimed at meeting the needs of the domestic market and at increasing competitiveness of Russian products abroad. The development of the Russian export strategy for agricultural products is currently very important. This problem is closely related to the general subject of the agricultural productiondevelopment, but it has an explicit specific character. Inthiscontextexperienceofforeigncountriesisinteresting. Almost all tools of export regulation existing in the world practice are used in the foreign practice of export regulation of agricultural raw materials and food. Stimulation measures prevail in regards to the coverage of commodity items, number of episodes involving the use of agricultural export regulationmeasures, effectiveness of impact to the national agricultural sector. Holistic strategies of agricultural export development are not a widespread phenomenon abroad at the present stage of the world economy development. Their existence is typical for countries with a high level of food self-sufficiency. Special programs where export component is a harmonically built-in element are now more widely spread. Export development programs of the developed countries include a range of measures to maintain the target income level of producers and to maintain procurement and consumer prices. Export policy of the developing countries has a subordinated importance and is considered as one of the levels to develop national

  11. THE IMPACT OF AGRICULTURAL PRODUCTIVITY ON RURAL TO URBAN MIGRATION IN JAVA, INDONESIA

    Directory of Open Access Journals (Sweden)

    Renata Fauzia

    2013-11-01

    Full Text Available This paper investigates if the improvement of agricultural productivity will decrease rural to urban migration. Since rural to urban migration occurs due mainly to disparity between urban and agricultural wage, we assume that boosting agricultural income will reduce migration to urban areas. It is hypothesized that increase in agricultural productivity would result in a rise in agricultural wage, and hence income, ceteris paribus, reduces rural-urban migration. The data used in this study is the 2010 provincial statistics in West Java, Central Java, and East Java, Indonesia. The agricultural productivity and migration equations were estimated by using Ordinary Least Squares (OLS. The research findings may offer the suggestion to reduce rural to urban migration by boosting rural income through focusing the policy on agricultural productivity. Enhancing investment in agricultural sector such as increasing the number of subsidized fertilizer, adding agricultural labor and livestock, increasing education of rural people, and utilizing agricultural land resource are expected to increase agricultural output.Thus, it would also minimize the wage differential between urban and rural area.

This corresponds to Global Production Networks (gpn, a vertical integration with intensive extraterritorial interaction resulting in a process of productive escalation that favors; learning and the creation of new competitive capabilities indispensable to comply with high standards in international markets. These capabilities are reflected in improvements in product quality, productive efficiency and the development of new functions for the players involved in the production and trade of produce. It also reflects the transition to more sophisticated productive units where players are located in other territories. This study focuses on analyzing the roll of gpn in the transformation of the agricultural sector in the northwest region of Mexico, particularly the process that took place in modernizing both places.

    This paper reviews recent literature concerning a wide range of processes through which climate change could potentially impact global-scale agricultural productivity, and presents projections of changes in relevant meteorological, hydrological and plant physiological quantities from a climate model ensemble to illustrate key areas of uncertainty. Few global-scale assessments have been carried out, and these are limited in their ability to capture the uncertainty in climate projections, and omit potentially important aspects such as extreme events and changes in pests and diseases. There is a lack of clarity on how climate change impacts on drought are best quantified from an agricultural perspective, with different metrics giving very different impressions of future risk. The dependence of some regional agriculture on remote rainfall, snowmelt and glaciers adds to the complexity. Indirect impacts via sea-level rise, storms and diseases have not been quantified. Perhaps most seriously, there is high uncertainty in the extent to which the direct effects of CO(2) rise on plant physiology will interact with climate change in affecting productivity. At present, the aggregate impacts of climate change on global-scale agricultural productivity cannot be reliably quantified.

    Climate change is projected to negatively impact biophysical agricultural productivity in much of the world. Actions taken to reduce greenhouse gas emissions and mitigate future climate changes, are thus of central importance for agricultural production. Climate impacts are, however, not unidirectional; some crops in some regions (primarily higher latitudes) are projected to benefit, particularly if increased atmospheric carbon dioxide is assumed to strongly increase crop productivity at large spatial and temporal scales. Climate mitigation measures that are implemented by reducing atmospheric carbon dioxide concentrations lead to reductions both in the strength of climate change and in the benefits of carbon dioxide fertilization. Consequently, analysis of the effects of climate mitigation on agricultural productivity must address not only regions for which mitigation is likely to reduce or even reverse climate damages. There are also regions that are likely to see increased crop yields due to climate change, which may lose these added potentials under mitigation action. Comparing data from the most comprehensive archive of crop yield projections publicly available, we find that climate mitigation leads to overall benefits from avoided damages at the global scale and especially in many regions that are already at risk of food insecurity today. Ignoring controversial carbon dioxide fertilization effects on crop productivity, we find that for the median projection aggressive mitigation could eliminate approximately 81% of the negative impacts of climate change on biophysical agricultural productivity globally by the end of the century. In this case, the benefits of mitigation typically extend well into temperate regions, but vary by crop and underlying climate model projections. Should large benefits to crop yields from carbon dioxide fertilization be realized, the effects of mitigation become much more mixed, though still positive globally and beneficial in many

    With the rapid development of the economy and population, water scarcity and poor water quality caused by water pollution have become increasingly severe in China. Virtual water trade is a useful tool to alleviate water shortage. This paper focuses on a comprehensive study of China's international virtual water flows from agricultural products trade and completes a diachronic analysis from 2001 to 2013. The results show that China was in trade surplus in relation to the virtual water trade of agricultural products. The exported virtual water amounted to 29.94billionm(3)/yr. while 155.55billionm(3)/yr. was embedded in imported products. The trend that China exported virtual water per year was on the decline while the imported was on a rising trend. Virtual water trade of China was highly concentrated. Not all of the exported products had comparative advantages in virtual water content. Imported products were excessively concentrated on water intensive agricultural products such as soya beans, cotton, and palm oil. The exported virtual water mainly flowed to the Republic of Korea, Hong Kong of China and Japan, while the imported mainly flowed from the United States of America, Brazil and Argentina. From the ethical point of view, the trade partners were classified into four types in terms of "net import" and "water abundance": mutual benefit countries, such as Australia and Canada; unilateral benefit countries, such as Mongolia and Norway; supported countries, such as Egypt and Singapore; and double pressure countries, such as India and Pakistan. Virtual water strategy refers to water resources, agricultural products and human beings. The findings are beneficial for innovating water resources management system, adjusting trade structure, ensuring food security in China, and promoting the construction of national ecological security system.

    Radiations and radioisotopes are used in agricultural research to develop improved crop varieties, to manage insect pests, monitor fate of pesticides, to study fertilizer and plant micronutrient uptake and to preserve agricultural produce. This is one of the important fields of peaceful applications of atomic energy for societal benefit. Department of Atomic Energy (DAE) has contributed significantly in this area especially in the development of new mutant crop varieties which are benefitting the farmers in enhancing their productivity. With an effective blend of induced mutagenesis and recombination breeding, 42 new crop varieties developed at Bhabha Atomic Research Centre (BARC) have been released and Gazette notified by the Ministry of Agriculture, Government of India for commercial cultivation. These include 21 in oilseeds (15-groundnut, 3 mustard , 2 soybean, 1 sunflower), 19 in pulses (8-mungbean, 5-urdbean, 5-pigeonpea, 1-cowpea) and one each in rice and jute. Some of the desirable traits which have been bred through induced mutations in these crops include higher yields, improved quality traits, early maturity and resistance to biotic and abiotic stress. Several of these varieties have high patronage from the farming community and are grown extensively across the country. Groundnut varieties have given record yields in farmer's fields. Pulses such as mung, urid and tur are popular among farmers in view of their disease resistance and suitability to rice fallow situations. Many of the breeding programmes in national/state systems have been utilizing BARC varieties as parental materials/donors and have developed several other improved varieties using them. (author)

    on production, land use and farm income in Finland. The results suggest that falling crop yields, if realized due to low prices and restrictive policies, will result in decreasing crop and livestock production and increasing nutrient surplus. Slowly increasing crop yields could stabilise production and increase farm income. Significantly higher crop prices and yields are required, however, for any marked increase in production in Finland. Cereals production would increase relatively more than livestock production, if there were high prices for agricultural products. This is explained by abundant land resources, a high opportunity cost of labour and policies maintaining current dairy and beef production.

    In many countries of the world, food demand exceeds the total agricultural production. In semi-arid countries, agricultural water demand often also exceeds the sustainable supply of water resources. These water-stressed countries are expected to become even drier, as a result of global climate change. This will have a significant impact on the future of the agricultural sector and on food security. The aim of the AGWATER project consortium is to provide recommendations for climate change adaptation for the agricultural sector in Cyprus and the wider Mediterranean region. Gridded climate data sets, with 1-km horizontal resolution were prepared for Cyprus for 1980-2010. Regional Climate Model results were statistically downscaled, with the help of spatial weather generators. A new soil map was prepared using a predictive modelling and mapping technique and a large spatial database with soil and environmental parameters. Stakeholder meetings with agriculture and water stakeholders were held to develop future water prices, based on energy scenarios and to identify climate resilient production systems. Green houses, including also hydroponic systems, grapes, potatoes, cactus pears and carob trees were the more frequently identified production systems. The green-blue-water model, based on the FAO-56 dual crop coefficient approach, has been set up to compute agricultural water demand and yields for all crop fields in Cyprus under selected future scenarios. A set of agricultural production and water use performance indicators are computed by the model, including green and blue water use, crop yield, crop water productivity, net value of crop production and economic water productivity. This work is part of the AGWATER project - AEIFORIA/GEOGRO/0311(BIE)/06 - co-financed by the European Regional Development Fund and the Republic of Cyprus through the Research Promotion Foundation.

    Past atmospheric nuclear testing which have been conducted frequently, have caused environmental pollution due to the diffusion of radioactive substances into the atmosphere and from the radioactive fallout. The environmental pollution from nuclear testing into the atmosphere has resulted in the radioactive contamination in agricultural products and has continued for a long time. The radioactive contamination of agricultural products occurs through air, water and soil which were contaminated by radioactive fallout. In this paper, for the purpose of analyzing the extent of the radioactive contamination levels in the agricultural products of Saitama Prefecture, spinach, green soybeans, dried shiitake and welsh onion, were selected among products, as the amount of the harvest is abundant in all of Japan. Radioactivity concentration was investigated by gamma-ray spectrometry and radiochemical analysis. The radioactivity concentrations of artificial radioactive nuclides, cesium-137 ({sup 137}Cs) and strontium-90 ({sup 90}Sr), were detected in the range which is considered to be the result of radioactive fallout. Moreover, in order to examine the effect on radioactivity concentrations in agricultural products by culinary processing, the raw agricultural products were boiled, and their radioactivity concentrations were compared with the raw produce. The radioactivity concentrations in the boiled were lower than those in the raw produce. (author)

    Sustainable food production for a growing world population requires a healthy soil that can buffer environmental extremes and minimize its losses. There are currently two views on how to achieve this: by intensifying conventional agriculture or by developing organically based agriculture. It has been established that yields of conventional agriculture can be 20% higher than of organic agriculture. However, high yields of intensified conventional agriculture trade off with loss of soil biodiversity, leaching of nutrients, and other unwanted ecosystem dis-services. One of the key explanations for the loss of nutrients and GHG from intensive agriculture is that it results in high dynamics of nutrient losses, and policy has aimed at reducing temporal variation. However, little is known about how different agricultural practices affect spatial variation, and it is unknown how soil fauna acts this. In this study we compare the spatial and temporal variation of physical, chemical and biological parameters in a long term (13-year) field experiment with two conventional farming systems (low and medium organic matter input) and one organic farming system (high organic matter input) and we evaluate the impact on ecosystem services that these farming systems provide. Soil chemical (N availability, N mineralization, pH) and soil biological parameters (nematode abundance, bacterial and fungal biomass) show considerably higher spatial variation under conventional farming than under organic farming. Higher variation in soil chemical and biological parameters coincides with the presence of 'leaky' spots (high nitrate leaching) in conventional farming systems, which shift unpredictably over the course of one season. Although variation in soil physical factors (soil organic matter, soil aggregation, soil moisture) was similar between treatments, but averages were higher under organic farming, indicating more buffered conditions for nutrient cycling. All these changes coincide with

In Argentina there is an important diversity of species available to be incorporated into production systems, giving support for the use of natural resources based on taking advantage of the regional fauna. Moreover the use of different animal species can be incorporated under the concept of the optimization of flows of energy and materials, tending to minimize the environmental impact of livestock production, and also to make more efficient use of the ingredients required for developing the activity. The integration of non-traditional species (minilivestock within the context of sustainable agricultural development was the motivation for the present study A module for raising Myocastor coypus (coypu or false nutha was developed, to which was linked a module for raising Eisenia foetida (the socalled red worm, in both cases with a dual purpose. Preliminary estimates were made of the productive aspects of both species, as well as an analysis of their integration, to understand the extent to which diversification linked with complementation tends to optimize the system.

    Full Text Available Analysis of the characteristics of agricultural product price volatility and trend forecasting are necessary to formulate and implement agricultural price control policies. Taking wholesale cabbage prices as an example, a multiple test methodology has been adopted to identify the nonlinearity, fractality, and chaos of the data. The approaches used include the R/S analysis, the BDS test, the power spectra, the recurrence plot, the largest Lyapunov exponent, the Kolmogorov entropy, and the correlation dimension. The results show that there is chaos in agricultural wholesale price data, which provides a good theoretical basis for selecting reasonable forecasting models as prediction techniques based on chaos theory can be applied to forecasting agricultural prices.

    Full Text Available The agricultural use of waste products represents an interesting alternative for nutrient cycling. Biodigested vinasse, the final waste product of vinasse biodigestion and biogas production, can be reused for agricultural purposes. The present work sought to quantify the shoot dry mass production of lettuce plants, as well as foliar nitrogen, phosphorus and potassium content following the application of biodigested vinasse on soil. Biodigested vinasse was produced from anaerobic vinasse digestion, using anaerobic sludge as a source of microorganisms. The treatments, with four replications in entirely randomized design, consisted of anaerobic sludge from a gelatin factory, vinasse in natura, biodigested vinasse and a control treatment. The experiment was conducted over 45 days using 5 L vases and applying a dose equivalent to 150 m3 ha-1 . Lettuce treated with biodigested vinasse showed higher shoot dry mass production and higher accumulation of nitrogen, phosphorus and potassium in its leaves than that treated with vinasse in natura.

    Full Text Available In the year 2007 there was price jump at world milk market. In the middle of the year 2008 the market was temporarily stabilized, because European Commission introduced Common Agricultural Policy modernization suggestion to the members of the European Parliament as the answer to an increasing food demand. The main elements of this suggestion were to abolish obligation to keep some agricultural areas set aside, milk quota removal, and abolition of subvention rate - production quantity link. When East and Central European countries entered in the European Union, they faced agricultural tax and milk price decrease. Today in new member states, the protection taxes are lower then before entering the Union (exceptions are Poland and Romania. The production costs in new member states are higher then in the Union, so there is higher market pressure at milk producers to increase their capacity (Livestock unit, to increase capacity utilization (milk per animal, and to produce at lower cost price. One part of smaller producers could not react to this pressure, so they decided to leave the dairy business. The consequence is decreased export of milk and dairy products in the new member states. Today milk market production in Croatia is around 650 million liters. In the production, there are around 32 thousand producers with 177 thousand of dairy cows. In the last 5 years of Croatian dairy, there was important shift in the production and redemption. Help to dairy sector through annual high investments as state subsidies and credit loans, and dairy industry subsidies at basic price, made redemption increase of more then 150 million liters, but also milk producer’s decrease. To stay at present production and redemption level, the only one that counts as Quota I, with around 90 % standard milk, there is a need to increase standard milk for 119 million liters.

    Radiation exposure has been paid attention as an alternative technique of methylbromide to protect agricultural products against insects. However, it has been pointed out that radiation at a dose lower than 300-400 Gy necessary for insecticidal effects might produce damages in fresh agricultural products. To reduce such radiation damages, radiation sensitivities of various fresh products were determined to clarify whether sugar treatment is effective for reduction of damages. Further, the timing of the treatment and its influence on the metabolism of agricultural product were investigated. When sucrose was added to a cut flower of chrysanthemum via water before and during irradiation, the withering time of its leaves and flowers was earlier than that of the untreated product, whereas continuous administration of sucrose after radiation exposure caused to lengthen the flower's life and delay the leave's yellowing. Thus, it was indicated that continuous sugar supply after irradiation was effective for prevention of radiation damages. (M.N.)

    Full Text Available Based on the results of the hygienic assessment of working conditions in the domestic agricultural machinery of old and new models when performing the main types of seasonal agricultural work during the annual production cycle and analysis of accumulated occupational diseases’ nosology structure in agricultural workers of the Saratov region over the period from 2004 to 2014, the estimation of professional risk diseases of the peripheral nervous system in tractor drivers – machine operators of agricultural production is given. Professional risk assessment carried out under the procedure set forth in P2.2.1766-03 has shown that the category of a priori risk to their health during an annual production cycle ranged from high to very high (unbearable. It was revealed that the most important factors shaping the harmful working conditions when working on agricultural machinery that can act as a trigger in the formation of vertebral diseases of the peripheral nervous system, are general and local vibration, adverse micro-climatic conditions, long uncomfortable static working posture and physical stress. The risk of diseases in the peripheral uneven system in machine operators of agriculture was attributed to the high risk category with an index of professional diseases (IPD equal to 0,5 %.

    Science.gov (United States)

    Dietzel, Anne; Rahn, Eric; Stamm, Christian

    2014-05-01

    Swiss agriculture is legally committed to fulfill several, partially conflicting goals such as agricultural production on the one hand and the conservation of natural resources on the other hand. In the context of the research project AProWa ("Agricultural Production and Water"), the relationships between the production aspect and the conservation of aquatic ecosystems is analyzed with a holistic approach. Agricultural production and the protection of water resources have high potential for conflicts: Farmers use ground and surface water to irrigate their fields. On the other hand, drainage systems enable the production on otherwise unfavorably wet soils. These in turn often affect ground water recharge and divert precipitation directly into surface waters, which changes their hydrological regime. Typically, drainage systems also elevate the input of nutrients and pesticides into the water bodies. In general, applied fertilizers, plant protection products, veterinary drugs and phytohormones of cultivated plants are introduced into the ground and surface waters through different processes such as drift, leaching, runoff, preferential flow or erosion. They influence the nutrient cycles and ecological health of aquatic systems. The nutrient and pesticide loss processes themselves can be altered by tillage operations and other agricultural practices. Furthermore, the competition for space can lead to additional conflicts between agriculture and the protection of aquatic ecosystems. For example, channelized or otherwise morphologically changed rivers do not have a natural discharge pattern and are often not suitable for the local flora and fauna; but naturally meandering rivers need space that cannot be used for agriculture. In a highly industrialized and densely populated country like Switzerland, all these potential conflicts are of importance. Although it is typically seen as a water-rich country, local and seasonal overexploitation of rivers through water extraction

Employing spatial autocorrelation analysis and a geographically weighted regression (GWR model, we explored the spatial variations of the WF and their relationships with agricultural inputs from 1998 to 2012 in Northeast China. The results indicated that: (1 the spatial distribution of WFs for the 36 major maize production prefectures was heterogeneous in Northeast China; (2 a cluster of high WFs was found in southeast Liaoning Province, while a cluster of low WFs was found in central Jilin Province, and (3 spatial and temporal differentiation in the correlations between the WF of maize production and agricultural inputs existed according to the GWR model. These correlations increased over time. Our results suggested that localized strategies for reducing the WF should be formulated based on specific relationships between the WF and agricultural inputs.

    Scanning electron microscopy is a useful tool for understanding food contamination and directing product development of food and industrial products. The current trend in food research is to produce foods that are fast to prepare and/or ready to eat. At the same time, these processed foods must be safe, high quality and maintain all or most of the nutritional value of the original whole foods. Minimally processed foods, is the phrase used to characterize these "new" foods. New techniques are needed which take advantage of minimal processing or processing which enhances the fresh properties and characteristics of whole foods while spending less time on food preparation. The added benefit coupled to less cooking time in an individual kitchen translates to an overall energy savings and reduces the carbon emissions to the environment. Food processing changes the microstructure, and therefore, the quality, texture and flavor, of the resulting food product. Additionally, there is the need to reduce waste, transportation costs and product loss during transportation and storage. Unlike food processing, structural changes are desirable in co-products as function follows form for food packaging films and boxes as well as for building materials and other industrial products. Thus, the standard materials testing procedures are coupled with SEM to provide direction in the development of products from agricultural residues or what would otherwise be considered waste materials. The use of agricultural residues reduces waste and adds value to a currently underutilized or unutilized product. The product might be biodegradable or compostable, thus reducing landfill requirements. Manufacturing industrial and packaging products from biological materials also reduces the amount of petroleum products currently standard in the industry.

    Full Text Available The aim of the article is to conduct an analysis of the agricultural products market in Ivano-Frankivsk region by assessing the main channels for selling products and the price level. By summarizing and analyzing the research of domestic scientists, the importance of conducting a qualitative and detailed market research in the system of intermediary activity is substantiated. Due to the results of the analysis of channels for selling agricultural products, it is revealed that intermediary structures have the largest market share. It is found that there is a tendency to increase the share of sold agricultural products to intermediaries both in Ukraine in general and in Ivano-Frankivsk region in particular. At the same time, direct sales on the market, and, therefore, direct contact with the end user, are decreasing year by year. Prospects for further research in this direction are searching for ways to reduce control over the agricultural market by intermediary structures.

    Full Text Available Sustainable crop production intensification should be the first strategic objective of innovative agronomic research for the next 40 years. A range of options exist (often very location specific for farming practices, approaches and technologies that ensure sustainability, while at the same time improving crop production. The main challenge is to encourage farmers in the use of appropriate technologies,  and  to  ensure  that  knowledge  about  sound  production  practices  is  increasingly accepted and applied by farmers. There is a huge, but underutilized potential to link farmers’ local knowledge with science-based innovations, through favourable institutional arrangements.  The same  holds  for  the  design,  implementation  and  monitoring  of  improved  natural  resource management  that  links  community  initiatives  to  external  expertise.  It is also suggested that a comprehensive effort be undertaken to measure different stages of the innovation system, including technological adoption and diffusion at the farm level, and to investigate the impact of agricultural policies on technological change and technical efficiency. This paper provides a brief review of agronomic management practices that support sustainable crop production system and evidence on developments  in the selection of crops and cultivars; describes farming systems for crop which take a predominantly ecosystem approach; discusses the scientific application of ecosystem principles for the management of pest and weed populations; reviews the  improvements in fertilizer and nutrient management that explain productivity growth; describes the benefits and constraints of irrigation technologies; and suggests a way forward. Seven changes in the context for agricultural development are proposed that heighten the need to examine how innovation occurs in the agricultural sector.

    2017-03-01

    Full Text Available Energy production by agricultural biogas plants has recently recorded considerable growth in Visegrad countries. The development was enhanced by European Union’s efforts to increase the proportion of energy produced from renewable sources. The paper aims to assess the role of energy policy in the development of agricultural biogas energy production in Visegrad region. Conducted studies have shown that among various forms of support for energy production from renewable energy sources, the price system prevails, including the support by feed in tariffs and bonuses. Feed in tariffs were adopted in Czech Republic, Hungary and Slovakia. Another kind of support system – a quota system – was adopted in Poland, what includes tendering and certificate systems. The results confirm the adoption of legal framework was necessary step to enable agricultural biogas energy production in Visegrad countries, but itself it was not enough to stimulate development of agricultural biogas energy production significantly. Rapid development in each country was recorded only after the certain financial support systems took effect, what made production of agricultural biogas energy economically efficient for investors. The production of energy from agricultural biogas grew the most in the Czech Republic and Slovakia, where the financial support was the highest. Nevertheless, the protracted process of changes in legal framework and transformation of energy policy, certain measures including state-controlled price-making systems, risk regarding with auction system might hamper agricultural biogas energy production further development.

  11. Using Very High Resolution Remotely Sensed Imagery to Estimate Agricultural Production: A comparison of food insecure and secure growing areas in Kenya

    Determining the amount of food produced in a food insecure, isolated, subsistence farming community can be used to help identify households or communities who may be in need of additional food resources. Measuring annual food production in developing countries, much less at a sub-national level, is complicated by lack of data. It can be difficult and costly to access all of the farming households engaged in subsistence farming. However, recent research has focused on the use of remotely sensed data to aid in the estimation of area under cultivation and because food production is the measure of yield (production per hectare) multiplied by area (number of hectares), we can use the area measure to reduce uncertainty in food production estimates. One strategy for estimating cultivated area relies on a fairly time intensive manual interpretation of very high resolution data. Due to the availability of very high resolution data it is possible to construct estimates of cultivated area, even in communities where fields are small. While this strategy has been used to effectively estimate cultivated area in a timely manner, questions remain about the spatial and temporal generalizability of this approach. The purpose of this paper is to produce and compare estimates of cultivated area in two very different agricultural areas of Kenya, a highly food insecure country in East Africa, during two different agricultural seasons. The areas selected represent two different livelihood zones: a marginal growing area where poor farmers rely on inconsistent rainfall and a lush growing area near the mountainous region of the middle-West area of the country where rainfall is consistent and therefore more suited to cultivation. The overarching goal is to determine the effectiveness of very high resolution remotely sensed imagery in calculating estimates of cultivated area in areas where food production strategies are different. Additionally the results of this research will explore the

    Through literature review, the article points out that the existing of the high-efficiency agriculture definition is limited to results oriented thinking, apparently lack of process oriented thinking. Combined with the connotation of fusion agriculture and tourism, respectively from the time and space utilization efficiency, cash cost, elements of input and output form, etc, gives high-efficiency agriculture a new connotation. Under the perspective of a combined agriculture with tourism, efficient use of time and space, low realized cost, less costs and output form of agriculture, this is highly effective agriculture.

    Agriculture is the largest global consumer of freshwater. As the volume of international trade continues to rise, so does the understanding that trade of water-intensive crops from areas with high precipitation, to arid regions can help mitigate water scarcity, highlighting the importance of crop water accounting. Virtual-Water, or Water-Footprint [WF] of agricultural crops, is a powerful indicator for assessing the extent of water use by plants, contamination of water bodies by agricultural practices and trade between countries, which underlies any international trade of crops. Most available studies of virtual-water flows by import/export of agricultural commodities were based on global databases, which are considered to be of limited accuracy. The present study analyzes the WF of crop production, import, and export on a country level, using Israel as a case study, comparing data from two high-resolution local databases and two global datasets. Results for local datasets demonstrate a WF of ~1200Million Cubic Meters [MCM]/year) for total crop production, ~1000MCM/year for import and ~250MCM/year for export. Fruits and vegetables comprise ~80% of Export WF (~200MCM/year), ~50% of crop production and only ~20% of the imports. Economic Water Productivity [EWP] ($/m 3 ) for fruits and vegetables is 1.5 higher compared to other crops. Moreover, the results based on local and global datasets varied significantly, demonstrating the importance of developing high-resolution local datasets based on local crop coefficients. Performing high resolution WF analysis can help in developing agricultural policies that include support for low WF/high EWP and limit high WF/low EWP crop export, where water availability is limited.

    Full Text Available With rapid and continuous population growth and the associated declining quality of cultivated land, food security in China has been attracting the attention of scholars both domestically and internationally. In recent decades, the implications of the cultivated land balance policy have promoted spatial changes of cultivated land. Estimating the agricultural potential productivity and assessing its response to cultivated land changes could provide a scientific basis for strategic decision-making concerning grain production and thus guarantee food security. In the present study, the Agro-Ecological Zone (AEZ model was applied to estimate the agricultural potential productivity. Data from the second national land survey were first applied to characterize the changes of cultivated land (by comparing the cultivated land in 2009 with that in 2012 and their influence on potential productivity in Mainland China. We propose a utilization degree of total potential productivity (UTP and its ratio coefficient (RUTP to reveal the utilization status of potential productivity and its change characteristics at the provincial level. It was found that there was a trend for cultivated land to be shifted away from cities, and the average productive capability per hectare of cultivated land declined from 7386.5 kg/ha to 6955.2 kg/ha by occupying highly productive cultivated land generally near the cities and compensating less productive cultivated land in remote areas. UTPs and RUTPs indicate a significant difference in the utilization status of potential productivity among the 31 provinces of Mainland China. Grain production with the aim of sustainable development should be strategized according to the particular facts of each province. The methods we applied can mine the impacts of cultivated land changes on potential productivity and the utilization of potential productivity effectively.

  17. Agricultural production and nutrient runoff in the Corn Belt ...

    Science.gov (United States)

    Agricultural production in the Corn Belt region of the Upper Mississippi River Basin (UMRB) remains a leading source of nitrogen runoff that contributes to the annual hypoxic 'Dead Zone' in the Gulf of Mexico. The rise of corn production, land conversion, and fertilizer use in response to ethanol policy incentives in recent years is well documented and may worsen this effect. We develop a spatially distributed dynamic environmental performance index (EPI), accounting for both desirable agricultural outputs and undesirable nonpoint source emissions from farm production, to examine the corresponding changes in environmental performance within the UMRB between 2002 and 2007, which is characterized by increasing policy incentives for ethanol production. County-level production data from the USDA agricultural census are aggregated to hydrologic unit code (HUC8) boundaries using a geographic information system (GIS), and a previously developed statistical model, which includes net anthropogenic nitrogen inputs (NANI) as well as precipitation and land use characteristics as inputs, is used to estimate annual nitrogen loadings delivered to streams from HUC8 watersheds. The EPI allows us to decompose performance of each HUC8 region over time into changes in productive efficiency and emissions efficiency. To our knowledge, this is the first study to examine the corresponding changes in environmental performance for producers in this region at the watershed scale. The resu

    Vast areas of arable land have been retired from crop production and “rehabilitated” to improved system states through landowner incentive programs in the United States (e.g., Conservation and Wetland Reserve Programs), as well as Europe (i.e., Agri-Environment Schemes). Our review of studies conducted on invasion of rehabilitated agricultural production systems by nontarget species elucidates several factors that may increase the vulnerability of these systems to invasion. These systems often exist in highly fragmented and agriculturally dominated landscapes, where propagule sources of target species for colonization may be limited, and are established under conditions where legacies of past disturbance persist and prevent target species from persisting. Furthermore, rehabilitation approaches often do not include or successfully attain all target species or historical ecological processes (e.g., hydrology, grazing, and/or fire cycles) key to resisting invasion. Uncertainty surrounds ways in which nontarget species may compromise long term goals of improving biodiversity and ecosystem services through rehabilitation efforts on former agricultural production lands. This review demonstrates that more studies are needed on the extent and ecological impacts of nontarget species as related to the goals of rehabilitation efforts to secure current and future environmental benefits arising from this widespread conservation practice.

    Full Text Available The development of agriculture was a priority for the member states of the European Union since its foundation, the Common Agricultural Policy being one of the most ancient politics at the European level. Agriculture is a sector which has a special economic and social importance for Romania. The paper aimed to identify the challenges of the agricultural companies from the perspective of labour productivity and funding access. In this respect, a series of economic indicators as the contribution of agriculture to GDP, the value of agricultural production, the evolution of reference interest rate, the evolution of credits for agriculture, were studied. the conclusion was that in order to improve labour productivity, it is needed a higher qualification of the occupied population in agriculture and the significant improvement of technological endowment of this sector and, from the point of view of funding access, it is necessary the continuous support of the companies which carry out their activity in agriculture, but not only by the diminution of difference interest rate.

    2015-08-01

    Full Text Available Abstract Modern agriculture is characterized by a series of conflicting optimization criteria that obstruct the decision-making process in the planning of agricultural production. Such criteria are usually net profit total cost total production etc. At the same time the decision making process in the agricultural production planning is often conducted with data that accidentally occur in nature or that are fuzzy not deterministic. Such data are the yields of various crops the prices of products and raw materials demand for the product the available quantities of production factors such as water labor etc. In this paper a fuzzy multi-criteria mathematical programming model is presented. This model is applied in a region of 10 districts in Sri Lanka where paddy is cultivated under irrigated and rain fed water in the two main seasons called Yala and Maha and the optimal production plan is achieved. This study was undertaken to find out the optimal allocation of land for paddy to get a better yield while satisfying the two conflicting objectives profit maximizing and cost minimizing subjected to the utilizing of water constraint and the demand constraint. Only the availability of land constraint is considered as a crisp in nature while objectives and other constraints are treated as fuzzy. It is observed that the MOFLP is an effective method to handle more than a single objective occurs in an uncertain vague environment.

    Full Text Available The objective of this study is to enhance understanding on how a firm can generate value for its customers using a competitive advantage strategy by accumulating credible attributes to its products. There are certain product attributes that customers can only perceive. In the case of agricultural food products, the customers’ consciousness for safe, natural and organic products has enriched the perceived value of the product. To explore the relationship between the credence attributes and attitude of the customers for the agricultural food, a survey questionnaire has been administered to consumers of agricultural food products in the different regions of Punjab, Pakistan. The data analysis has been conducted using the Statistical Package for Social Sciences (SPSS to investigate the desired relationship in that particular region of the country. It can be concluded that the trust of customer is now very much depending on the presence of credence attribute that customer cannot describe but evaluate during the purchase of food items.

    Full Text Available In the last 25 years Hungarian agriculture has lost its position. Rapid growth in the world’s population requires an increase in food production since one seventh of the population is still starving. The development of agricultural production and the food industry is the basis for the development of rural areas. Hungary produces two per cent of the EU agricultural output, which is far behind its potential. Agriculture, food industry and food trade can only develop together. We need to find the most favourable forms of coexistence with multinational chains sustainably. Food industry is a critical point in the product line, it lags behind the performance of European countries, and resources are insufficient. Long-term co-operation between farmers and processors is inadequate; the common organizations of the markets are minimal. Today, sustainability is increasingly emphasized, environmental and nature protection has been appreciated. The agriculture and forestry sectors are not only suitable for production of food and other raw materials, but they can also replenish resources and have a beneficial effect on biodiversity as well. Today’s problems can only be solved by taking sustainability into consideration. Agri-food industry that complies with the requirements can play a major role in rural employment and value creation.

    For the consideration of the effects on radioactive contamination of agricultural products by rainfall during a nuclear accident, the wet interception coefficients for the plants were derived, and the previous dynamic food chain model was also modified. From the results, radioactive contamination of agricultural products was greatly decreased by rainfall, and it decreased dramatically according to increase of rainfall amount. It means that the predictive contamination in agricultural products using the previous dynamic food chain model, in which dry interception to the plants is only considered, can be overestimated. Influence of rainfall on the contamination of agricultural products was the most sensitive for 131 I, and the least sensitive for 90 Sr

    Group of Eight developed countries (D8 plus China. Technology spillover indexes are thus decomposed into two components: Imports of capital goods and foreign direct investment (FDI. Index of capital goods imports measures imports of capital goods from major commercial partners of Iran (D8 countries and china. Foreign direct investment (FDI represents the share of foreign capital in agricultural sectors. Therefore, the empirical analysis of the technology spillover on the productivity of agricultural sectors is based on theatrical framework and ARDL model. Results and Discussion: According to the results of the ARDL model, technological spillover effect on the TFP of agricultural sector, in long-term shows that technology spillover has a positive and significant effect on agricultural productivity from both channels of capital goods import and foreign direct investment (FDI. But in short-term spillover variable from a capital goods import channel is not significant. This indicates that absorption of the technology from imports of capital goods channel do not perform very well and probably low-tech and without affecting on TFP of agriculture sector is imported. But in long-term technology spillover from imports channels also had a positive impact on total factor productivity of the agricultural sector. In fact, high technologies in long-term can be absorbed through the imports and influenced on TFP. According to thesis study results, the estimated coefficient of error correction term is equal to 0.53.This means that in each period, 53 percent of imbalances of agricultural TFP will be resolved. The average speed of upward of adjustment reflects the fact that in Iran economy, deviations and imbalances have arisen in the agricultural sector TFP caused by technology spillovers shocks, move very fast towards long-run equilibrium. Conclusions: The purpose of this paper is to advance the knowledge for a key question with evident implications for economic policy: What is the

Feeding of grain fodder in the form of stock feed is inefficient and economically unreasonable. The article is devoted to actual problem - the preparation of mixed fodder in the conditions of agricultural enterprises. Review and critical analyses of mixed fodder assemblies and aggregates are given. Structural and technical schemes of small-size mixed fodder aggregate with intensified attachments of vibrating and percussive action for preparation of bulk feed mixture in the conditions of agricultural enterprises were developed. The mixed fodder aggregate for its preparation in the places of direct consumption from own grain fodder production and purchased protein and vitamin supplements is also suggested. Mixed fodder aggregate allows to get prepared mixed fodder of high uniformity at low cost of energy and price of production that is becoming profitable for livestock breeding. Model line-up of suggested mixed fodder aggregate with different productivity both for small and big agricultural enterprises is considered.

    This paper assesses the macroeconomic impacts in terms of GDP, trade balance and employment of large-scale bioenergy production on surplus agricultural land. An input-output model is developed with which the direct, indirect and induced macroeconomic impacts of bioenergy production and agricultural intensification, which is needed to make agricultural land become available for bioenergy production, are assessed following a scenario approach. The methodology is applied to a case study of Argentina. The results of this study reveal that large-scale pellet production in 2015 would directly increase GDP by 4%, imports by 10% and employment by 6% over the reference situation in 2001. When accounting for indirect and induced impacts, GDP increases by 18%, imports by 20% and employment by 26% compared to 2001. Agricultural intensification reduces but does not negate these positive impacts of bioenergy production. Accounting for agricultural intensification, the increase in GDP as a result of bioenergy production on surplus agricultural land would amount to 16%, 20% in imports and 16% in employment compared to 2001.

    Production of fuel ethanol from lignocellulosic feedstocks such as agricultural and forestry residues is receiving increasing attention due to the unsustainable supply of fossil fuels. Three key challenges include high cellulase production cost, toxicity of the cellulosic hydrolysate to microbial strains, and poor ability of fermenting microorganisms to utilize certain fermentable sugars in the hydrolysate. In this article, studies on searching of natural microbial strains for production of unique cellulase for biorefinery of agricultural and forestry wastes, as well as development of strains for improved cellulase production were reviewed. In addition, progress in the construction of yeast strains with improved stress tolerance and the capability to fully utilize xylose and glucose in the cellulosic hydrolysate was also summarized. With the superior microbial strains for high titer cellulase production and efficient utilization of all fermentable sugars in the hydrolysate, economic biofuels production from agricultural residues and forestry wastes can be realized.

Former UK colonies exhibited significantly higher productivity gains than others, while Liberia and countries that had been colonies of Portugal or Belgium exhibited net reductions in ...

  1. Insect disinfestation of food and agricultural products by irradiation

    International Nuclear Information System (INIS)

    1991-01-01

    Insect infestation is a major cause of post-harvest food loss. Use of chemical pesticides is one of the main methods of controlling storage losses caused by insects. Decades of research conducted worldwide on radiation disinfestation of food and agricultural products have shown that this method could be an alternative to the chemical treatment of foods. The advantages of irradiation processing include no undesirable residues in the foods, no resistance developed by the insects and no significant changes in the physicochemical properties or the nutritive value of the treated products. This volume contains the proceedings of the final Research Co-ordination Meeting on insect disinfestation of food and agricultural products by irradiation, held in May 1987. The individual contributions are indexed separately. Refs, figs and tabs

    This paper tests whether the strength of the "spring spike" in birth defects is related to agricultural production and urban location using Texas Birth Defects Registry data for the period 1996-2007. We find evidence of a spike in birth defects among children conceived in the spring and summer, but it is more pronounced in urban non-agricultural counties than in other types of counties. Furthermore, the spike lasts longer in urban non-agricultural counties as compared to other types of counties. Copyright © 2014 Elsevier B.V. All rights reserved.

    Full Text Available This study examined changes in agricultural productivity in Sub-Sahara Africa countries in the context of diverse institutional arrangements using Data Envelopment Analysis (DEA. From a time series which consists of information on agricultural production and means of production were obtained from FAO AGROSTAT and rainfall data from Steve O’Connell data base. The information was for a 43-year period (1961-2003; DEA method was used to measure Malmquist index of total factor productivity. A decomposition of TFP measures revealed that the observed increase in the TFP in the sub–Sahara Africa agriculture is due to technological change rather than efficiency change which is the main constrained of achieving higher level of TFP during the reference period. The study further examined the effect of land quality, malaria, education and selected governance indicators such as, control of corruption and government effectiveness on productivity growth. All the variables included in the model are significant with the exception of government effectiveness

    Full Text Available There is a growing competition among the various sectors of society in the world for the use of water where agriculture stands out as a major consumer. Since it is carried out in a controlled manner, irrigation with effluents from a Sewage Treatment Plant (STP is a very attractive practice, as it allows a greater supply of water for nobler purposes. This work had the general objective of evaluating the perception of a rural community in the municipality of Pesqueira, Pernambuco, Brasil, in terms of consumption and production of products cultivated with the practice of agricultural reuse. The local population showed acceptance for the cultivation and consumption of products through agricultural reuse, above all, with reliable information on the appropriate quality of the effluents used for irrigation. In the estimated data, the same community had a potential of production of corn, beans and cotton in the order of 19.8 tons, 3.4 tons and 7.7 tons respectively, with the use of treated sewage in irrigation.

    1994-01-01

    The study is part of a research project, 'Radioactivity problems within the food sector' performed in 1991-94 at the request of the National Board of Agriculture in Sweden by The National Research Establishment, Dept. of NBC Defence, and the Dept. of Radioecology and the Dept. of Biosystems and Technology, the latter two belonging to the Swedish Univ. of Agricultural Sciences. The aim of the study was to investigate the contamination levels that may occur in agricultural crop products in Sweden in a situation of radioactive fallout from the use of nuclear weapons. There is a risk for a major nuclide transport in agricultural systems by the feeds, mainly by pasture grass and silage and hay crops but also to some extent by grain crops. For that reason, cattle are expected to be important vectors of the fallout nuclides to the human diet, particularly in milk from dairy cattle but also in beef. The activity transport by grain to pig products may also be of some importance. 8 refs, 7 figs, 25 tabs

    Full Text Available In this study we investigated the relation between energy consumption and growth of total factor productivity (TFP of agriculture in Iran from 1974 to 2012 using Solow residual method. The results from estimated aggregate Cobb–Douglas production function showed that one percent change in the value of labor, capital and energy will lead to 4.07, 0.09 and 0.49 percent change in agriculture value added, respectively. Also in a long term, based on the Johansen cointegration test, there is a negative relation between TFP growth and energy consumption in Iranian agriculture which might be due to cheap and inefficient energy use in this sector. Gradual liberalization of energy price and use of so called green box support policies is recommended.

    The study of SAR Agriculture Rice Production Estimation (SARPE) was held in Indonesia on 2012, as part of Asia-Rice Crop Estimation & Monitoring (Asia-RiCE), which is a component for the GEO Global Agricultural Monitoring (GEOGLAM) initiative. The study was expected to give a breakthrough result, by using radar technology and paradigm shift of the standard production estimation system from list frame to area frame approach. This initial product estimation system is expected to be refined (fine tuning) in 2013, by participating as part of Technical Demonstration Site (Phase -1A) of Asia-RICE. The implementation period of this initial study was from the date of March 12 to December 10, 2012. The implementation of the study was done by following the approach of the BIMAS-21 framework, which has been developed since 2008. The results of this study can be briefly divided into two major components, namely: Rice-field Baseline Mapping (PESBAK - Peta Sawah Baku) and Crop Growth Monitoring. Rice-fields were derived from the mapping results of the Ministry of Agriculture (Kemtan), and validated through Student Extension Campaign of the Faculty of Agriculture, Bogor Agricultural University (IPB). While for the crop growth, it was derived from the results of image analysis process. The analysis was done, either on radar/Radarsat-2 (medium resolution) or optical/ MODIS (low resolution), based on the Planting Calendar (KATAM) of Kemtan. In this case, the planting season II/2012-2013 of rice production centers in West Java Province (Karawang, Subang and Indramayu counties). The selection of crop season and county were entirely dependent on the quality of the available PESBAK and procurement process of radar imagery. The PESBAK is still in the form of block instead of fields, so it can not be directly utilized in this study. Efforts to improve the PESBAK can not be optimal because the provided satellite image (ECW format) is not the original one. While the procurement process of

    Up to date, reliable, global, information on crop production prospects is indispensible for informing and regulating grain markets and for instituting effective agricultural policies. The recent price surges in the global grain markets were in large part triggered by extreme weather events in primary grain export countries. These events raise important questions about the accuracy of current production forecasts and their role in market fluctuations, and highlight the deficiencies in the state of global agricultural monitoring. Satellite-based earth observations are increasingly utilized as a tool for monitoring agricultural production as they offer cost-effective, daily, global information on crop growth and extent and their utility for crop production forecasting has long been demonstrated. Within this context, the Group on Earth Observations developed the Global Agricultural Monitoring (GEOGLAM) initiative which was adopted by the G20 as part of the action plan on food price volatility and agriculture. The goal of GEOGLAM is to enhance agricultural production estimates through the use of Earth observations. This talk will explore the potential contribution of EO-based methods for improving the accuracy of early production estimates of main export countries within the framework of GEOGLAM.

    This paper presents a mathematical model for agricultural fires based on a multi-phase formulation. The model includes dehydration and pyrolysis of agricultural fuel and pyrolysis products. The model considers a homogeneous distribution of the agricultural solid fuel particles, interacting with the gas flow via source terms. These terms include: drag forces, production of water vapour and pyrolysis products, radiative and convective heat exchange. A multi-phase radiative transfer equation for absorbing-emitting medium is considered to account for the radiative heat exchange between the gas and solid phases of the fire. The main outputs of the present model are most important to study the influence of agricultural fire occurring beneath high voltage transmission lines. The agricultural fire causes a flashover due to the ambient temperature rise and soot accumulation on the insulator of these transmission lines. Numerical results of the present model are obtained for flat grassland fires to study the effects of wind velocity, solid fuel moisture content and ignition length on some selected fire outputs. These outputs include the temperature, velocity, soot volume fraction fields of the gas phase, together with fire propagation rate and flame geometry. The numerical results are compared to the available experimental work in the literature. -- Research highlights: → The model is sensitive to the initial condition of the ignition length affecting the fire propagation rate and width. → The model predicts the effects of both the wind velocity and the fuel moisture content on fire propagation rate, in agreement with the available experimental work in the literature. → The model shows that both the wind velocity and the fuel moisture content are important factors affecting the fire plume thickness, location, and inclination. → The model is able to visualize the flame geometry through tracing radiative heat rates exceeding a threshold value for flame visibility (60 k

    Highlights: • This study quantifies the bioenergy production potential in the Canadian agricultural sector. • Two presented scenarios included the mix of market and non-market policy targets and the market-only drivers. • The scenario that used mix of market and policy drivers had the largest impact on the production of bioenergy. • The production of biomass-based ethanol and electricity could cause moderate land use changes up to 0.32 Mha. • Overall, agricultural sector has a considerable potential to generate renewable energy from biomass. - Abstract: Agriculture has the potential to supply considerable amounts of biomass for renewable energy production from dedicated energy crops as well as from crop residues of existing production. Bioenergy production can contribute to the reduction of greenhouse gas (GHG) emissions by using ethanol and biodiesel to displace petroleum-based fuels and through direct burning of biomass to offset coal use for generating electricity. We used the Canadian Economic and Emissions Model for Agriculture to estimate the potential for renewable energy production from biomass, the impacts on agricultural production, land use change and greenhouse gas emissions. We explored two scenarios: the first considers a combination of market incentives and policy mandates (crude oil price of $120 bbl −1 ; carbon offset price of $50 Mg −1 CO 2 equivalent and policy targets of a substitution of 20% of gasoline by biomass-based ethanol; 8% of petroleum diesel by biodiesel and 20% of coal-based electricity by direct biomass combustion), and a second scenario considers only carbon offset market incentives priced at $50 Mg −1 CO 2 equivalent. The results show that under the combination of market incentives and policy mandates scenario, the production of biomass-based ethanol and electricity increases considerably and could potentially cause substantial changes in land use practices. Overall, agriculture has considerable potential to

    In rapidly urbanizing semi-arid regions, increasing amounts of historically irrigated cropland lies permanently fallowed due to water court policies as agricultural water rights are voluntarily being sold to growing cities. This study develops an integrative framework for assessing the effects of population growth and land use change on agricultural production and evaluating viability of alternative management strategies, including alternative agricultural transfer methods, regional water ownership restrictions, and urban conservation. A partial equilibrium model of a spatially-diverse regional water rights market is built in application of the framework to an exemplary basin. The model represents agricultural producers as profit-maximizing suppliers and municipalities as cost-minimizing consumers of water rights. Results indicate that selling an agricultural water right today is worth up to two times more than 40 years of continued production. All alternative policies that sustain agricultural cropland and crop production decrease total agricultural profitability by diminishing water rights sales revenue, but in doing so, they also decrease municipal water acquisition costs. Defining good indicators and incorporating adequate spatial and temporal detail are critical to properly analyzing policy impacts. To best improve agricultural profit from production and sale of crops, short-term solutions include alternative agricultural transfer methods while long-term solutions incorporate urban conservation.

    In 1995-97, the Swedish Environmental Protection Agency carried out a futures study with the aim of identifying ways to achieve environmentally friendly, sustainable Swedish agriculture by 2021. The results indicated that major environmental improvements were possible, while also improving profitability and increasing production of food and bioenergy. At a time half way between 1995 and 2021, the trends predicted in that study were compared against actual developments in agriculture. The analysis showed that most objectives regarding environmental quality were on the way to being achieved relatively well. However, profitability continued to be weak, while food production had decreased and bioenergy production was far below the predicted level. The latter means that agriculture was far from achieving the target of compensating for its emissions of greenhouse gases through bioenergy production substituting for fossil energy. This analysis showed that weak profitability and insufficient production capacity at current prices are the greatest sustainability problems in Swedish agriculture. If profitability cannot be improved, agriculture will decline and its positive effects on the landscape will decrease. If production does not increase, there will have to be continued or increased food imports, which are often less favourable from an environmental perspective than food produced in Sweden. If bioenergy production in agriculture does not drastically increase, it will be difficult to realise the vision of a Sweden without net emissions of greenhouse gases by 2050. The present report updates the futures study. In the evaluation, great emphasis is placed on identifying paths to economically sustainable, high producing and climate-smart agriculture with high landscape values. It is assumed that the current agricultural support system is replaced with environmental payment based on landscape and climate benefits. The views expressed in this report are those of its author and

    One of the primary challenges of our time is to feed a growing and more demanding world population with reduced external inputs and minimal environmental impacts, all under more variable and extreme climate conditions in the future. Conservation agriculture represents a set of three crop management principles that has received strong international support to help address this challenge, with recent conservation agriculture efforts focusing on smallholder farming systems in sub-Saharan Africa and South Asia. However, conservation agriculture is highly debated, with respect to both its effects on crop yields and its applicability in different farming contexts. Here we conduct a global meta-analysis using 5,463 paired yield observations from 610 studies to compare no-till, the original and central concept of conservation agriculture, with conventional tillage practices across 48 crops and 63 countries. Overall, our results show that no-till reduces yields, yet this response is variable and under certain conditions no-till can produce equivalent or greater yields than conventional tillage. Importantly, when no-till is combined with the other two conservation agriculture principles of residue retention and crop rotation, its negative impacts are minimized. Moreover, no-till in combination with the other two principles significantly increases rainfed crop productivity in dry climates, suggesting that it may become an important climate-change adaptation strategy for ever-drier regions of the world. However, any expansion of conservation agriculture should be done with caution in these areas, as implementation of the other two principles is often challenging in resource-poor and vulnerable smallholder farming systems, thereby increasing the likelihood of yield losses rather than gains. Although farming systems are multifunctional, and environmental and socio-economic factors need to be considered, our analysis indicates that the potential contribution of no-till to the

    Full Text Available Agriculture sector plays an important role in the economic development of Pakistan. Wheat is an important and most cultivated crop because it is an essential ingredient of food commodities. Credit plays a vital role in agricultural farming by indirectly participating in purchasing of agricultural inputs i.e. seed, fertilizer, irrigation, machinery and labor etc. Majority of the farmers are poor and they are not able to fulfill the cash requirement of farming, therefore credit has become their dire need. Due to credit farmers can timely purchase the agricultural inputs which resulting a bumper crop. The objective of this study is to depict the impact of credit on the production of wheat crop. Survey was conducted and random sampling technique was used to select the sample borrowers. The collected data was interpreted through “Cobb Douglas Production Function” by using statistical software (SPSS 16.0. The results showed that credit has positive and significant impact on wheat production. The values of R2 and F-statistics are found significant which represented that all selected variables are highly significant. The study not only shares the importance of credit to perform any agriculture activity but also helpful for economists and policy makers for designing agri financing policies.

    Quality inspection of food and agricultural produce are difficult and labor intensive. Simultaneously, with increased expectations for food products of high quality and safety standards, the need for accurate, fast and objective quality determination of these characteristics in food products continues to grow. However, these operations generally in India are manual which is costly as well as unreliable because human decision in identifying quality factors such as appearance, flavor, nutrient, texture, etc., is inconsistent, subjective and slow. Machine vision provides one alternative for an automated, non-destructive and cost-effective technique to accomplish these requirements. This inspection approach based on image analysis and processing has found a variety of different applications in the food industry. Considerable research has highlighted its potential for the inspection and grading of fruits and vegetables, grain quality and characteristic examination and quality evaluation of other food products like bakery products, pizza, cheese, and noodles etc. The objective of this paper is to provide in depth introduction of machine vision system, its components and recent work reported on food and agricultural produce.

    Diverse vulnerabilities of Bangladesh's agricultural sector in 16 sub-regions are assessed using experiments designed to investigate climate impact factors in isolation and in combination. Climate information from a suite of global climate models (GCMs) is used to drive models assessing the agricultural impact of changes in temperature, precipitation, carbon dioxide concentrations, river floods, and sea level rise for the 2040-2069 period in comparison to a historical baseline. Using the multi-factor impacts analysis framework developed in Yu et al. (2010), this study provides new sub-regional vulnerability analyses and quantifies key uncertainties in climate and production. Rice (aman, boro, and aus seasons) and wheat production are simulated in each sub-region using the biophysical Crop Environment REsource Synthesis (CERES) models. These simulations are then combined with the MIKE BASIN hydrologic model for river floods in the Ganges-Brahmaputra-Meghna (GBM) Basins, and the MIKE21Two-Dimensional Estuary Model to determine coastal inundation under conditions of higher mean sea level. The impacts of each factor depend on GCM configurations, emissions pathways, sub-regions, and particular seasons and crops. Temperature increases generally reduce production across all scenarios. Precipitation changes can have either a positive or a negative impact, with a high degree of uncertainty across GCMs. Carbon dioxide impacts on crop production are positive and depend on the emissions pathway. Increasing river flood areas reduce production in affected sub-regions. Precipitation uncertainties from different GCMs and emissions scenarios are reduced when integrated across the large GBM Basins' hydrology. Agriculture in Southern Bangladesh is severely affected by sea level rise even when cyclonic surges are not fully considered, with impacts increasing under the higher emissions scenario.

    Despite accelerating globalization, most people still eat food that was grown locally. Developing countries with weak purchasing power tend to import as little food as possible from global markets, suffering consumption deficits during times of high prices or production declines. Local agricultural production, therefore, is critical to both food security and economic development among the rural poor. The level of local agricultural production, in turn, will be controlled by the amount and quality of arable land, the amount and quality of agricultural inputs (fertilizer, seeds, pesticides, etc.), as well as farm-related technology, practices, and policies. In this paper we discuss several emerging threats to global and regional food security, including declining yield gains that are failing to keep up with population increases, and warming in the tropical Indian Ocean and its impact on rainfall. If yields continue to grow more slowly than per capita harvested area, parts of Africa, Asia, and Central and Southern America will experience substantial declines in per capita cereal production. Global per capita cereal production will potentially decline by 14 percent between 2008 and 2030. Climate change is likely to further affect food production, particularly in regions that have very low yields due to lack of technology. Drought, caused by anthropogenic warming in the Indian and Pacific Oceans, may also reduce 21 st century food availability by disrupting Indian Ocean moisture transports and tilting the 21 st century climate toward a more El Nino-like state. The impacts of these circulation changes over Asia remain uncertain. For Africa, however, Indian Ocean warming appears to have already reduced main growing season rainfall along the eastern edge of tropical Africa, from southern Somalia to northern parts of the Republic of South Africa. Through a combination of quantitative modeling of food balances and an examination of climate change, we present an analysis of

    Full Text Available This study examines the participation of urban women in agricultural production activities in the Sokoto metropolis, Nigeria. Both primary data and secondary information were used in the study. The primary data were obtained using a structured questionnaire, administered to 72 respondents selected using the snowball sampling technique. Descriptive and inferential statistics were used to analyze the primary data generated. These include frequency and percentage, and Pearson product moment correlation, respectively. The results show that most of the urban women (38.9 % were in the active age range and had a family size of 1-5 persons (73.6 %. The majority attained tertiary education (62.5 % and have relatively low income (61.1 %, with monthly earnings of 5,000-99,000 Naira. The majority of the women were involved in agricultural production activities all year round (52.8 % with the highest participation seen in poultry farming (43.1 %. Although most of the women were motivated to participate for several reasons, it was mostly for the increased income (33.3 %. It was also found that the major constraint faced was inadequate capital (43.1 %. Age, marital status, educational attainment, household size and farm size were negatively and not significantly (p<5 % related to the participation of urban women in agricultural production activities. Monthly income was however, positively related to the urban women’s participation in agricultural production activities and was also significant (p<5 %. In general, urban women participate in agricultural production activities on a small scale all year round. Proper orientation and awareness programs, provision of credit and women-targeted agricultural programs would go a long way to improving the participation of urban women in agricultural production activities.

    2007-05-15

    The overall aim of this report is to analyse and describe the production conditions of bioenergy in Swedish agriculture and how these conditions can vary due to different factors. The conclusion is that the potential for producing bioenergy in Swedish agriculture will vary significantly depending on which energy crops are cultivated, which type of agricultural land is utilised and the geographical location of the production. Furthermore, different crop residues and other by-products from agriculture, utilised for energy purposes, will affect the bioenergy potential. To which extent this physical/biological potential will be utilised in the future depends mainly on economic conditions and financial considerations. These aspects are not included in this study. The report starts with a description of current crop production in Sweden, expressed in energy terms, the energy needed for this production and the regional variation in crop yields. The local variations in cultivation conditions are also analysed, as well as variations over the area of a single farm. Another aspect discussed is the production conditions of energy crops on previous farm land not currently utilised. The report includes an analysis of the potential supply of crop residues and other by-products for energy purposes, such as straw, tops and leaves of sugar beets, manure etc, as well as the regional variation of these residues and by-products. A similar analysis is made of the regional production conditions and potential biomass yields of traditional crops and new energy crops. These analyses also include energy balance calculations showing the energy input needed for different production systems in relation to the harvested biomass yield, and the potential for increased biomass yields in the future. Based on the findings of these various analyses, calculations are made showing some examples of how much bioenergy Swedish agriculture can deliver, depending on how much agricultural land is utilised for

    The demand for high-quality fibres and shives from hemp and flax as an alternative raw material for the automotive and building industry is increasing. Fibres are used primarily for composite reinforcement instead of synthetic fibres. Shives are used for animal bedding, but processing trials in wood industry for the production of low weight particle boards from shives are also very promising. Fibre producers require experience in cultivation and harvesting as well as modern processing technologies in order to supply flax fibres or shives at competitive prices under the changing conditions of international raw material markets. A complete processing line has been developed, installed and tested at the Leibniz Institute for Agricultural Engineering (ATB) to study all the processing stages of fibre production. The new ATB line can produce high quality fibres and shives from retted and unretted hemp, flax and oilseed flax straw without technical changes of the machine line. The ATB pilot plant has been operated by a cooperation of farmers since 2008. Experience from industrial operation has been used to develop a modern fibre processing line with a throughput of up to 5 t per h hemp straw in only one short line.

    Full Text Available One of the main problems of the world in the coming years is food security. The main problem of agriculture in the future is not only to produce more, but to do so in a sustainable way. European Innovation Partnership called "Productivity and sustainability of agriculture" aims to provide a working interface between agriculture, bio-economy, science and other disciplines at national, regional and EU level. European Innovation Partnership is a new concept that was introduced in Strategy Europe 2020 of the European Commission. In this document, the Commission underlines the role of research and innovation as key elements in adapting to future challenges of the European Union. This partnership will also serve as a catalyst to increase the effectiveness of actions related to innovation supported through rural development policy, EU research and innovation. It has been identified two main objectives for the European Innovation Partnership: promoting productivity and efficiency of agriculture and durable agriculture sustainability in all Member States. It aims to create a better cooperation between research and agricultural practice, namely farmers. Through National Program for Rural Development 2014 - 2020, can be financed such initiatives, through Measure 16, sub-16.1 - Support for the establishment and operation of operational groups of the EIP for agricultural productivity and sustainability and sub-16.2 - Support for pilot projects and development of new products, practices, processes and technologies. The purpose of these sub-measures is to support the establishment of operational groups between partners coming from research: research institutes, research stations or centers, higher education institutions that have research in agriculture or which can be applied in agriculture and agricultural producers (farmers, companies, cooperatives and producer groups. Development and innovation activities would enable farmers to capitalize on joint the

    A growing bioeconomy and increased demand for biomass products on food, health, fibre, industrial products and energy require land resources for feedstock production. It has resulted in significant environmental and socio-economic challenges on a global scale. As a result, consideration of such effects of land use change (LUC) from biomass production (particularly for biofuel feedstock) has emerged as an important area of policy and research, and several potential solutions have been proposed to minimise such adverse LUC effects. One of these solutions is the use of lands that are not in production or not suitable for food crop production, such as 'marginal', 'degraded', 'abandoned' and 'surplus' agricultural lands for future biomass production. The terms referring to these lands are usually associated with the potential production of 'marginal crops', which can grow in marginal conditions (e.g. poor soil fertility, low rainfall, drought) without much water and agrochemical inputs. In our research, we referred to these lands as 'underutilised' agricultural land and attempted to define them for our case study areas located in Australia and Central and Eastern Europe (CEE). Our goal is to identify lands that can be used for future biomass production and to evaluate their environmental implications, particularly impacts related to biodiversity, water and soil at a landscape scale. The identification of these lands incorporates remote sensing and spatially explicit approaches. Our findings confirmed that there was no universal or single definition of the term 'underutilised' agricultural land as the definitions significantly vary by country and region depending not only on the biophysical environment but also political, institutional and socio-economic conditions. Moreover, our results highlighted that the environmental implications of production of biomass on 'underutilised' agricultural land for biomass production are highly controversial. Thus land use change

    2013-01-01

    Nigeria′s Biofuels Policy introduced in 2007 mandates a 10% blend (E10) of bioethanol with gasoline. This study investigates the potential for the development of a cellulosic ethanol industry based on the availability of agricultural residues and models the number of commercial processing facilities that could be sited in the six Geo-political zones. The potential for cellulosic ethanol production from agricultural residues in Nigeria is 7556 km 3 per annum exceeding the mandate of 10% renewable fuel required and providing the potential for 12 large- and 11 medium-scale processing facilities based on the use of a single feedstock. Cassava and yam peelings provided in excess of 80% of the process residues available with enough feedstock to supply 10 large-scale facilities with a fairly even distribution across the zones. Sorghum straw, millet straw and maize stalks represented 75% of the potential resource available from field residues with the potential to supply 2 large- and 7 medium-scale processing facilities, all of which would be located in the north of the country. When a multi-feedstock approach is used, this provides the potential for either 29 large- or 58 medium-scale facilities based on outputs of 250 and 125 km 3 per annum respectively. - Highlights: • Nigeria′s Biofuels Policy mandates a 10% blend of bioethanol with gasoline. • Total bioethanol production from agricultural residues was 7556 km 3 per annum. • Process residues offer the greatest potential accounting for 62% of production. • Nigeria has the potential for 12 large- and 11 medium scale commercial. • The use of mixed feedstocks significantly increases the potential for production

    Continuous monitoring of chemical residues in agricultural and food products has been performed by various government bodies in South Korea. These bodies have made attempts to systematically manage this information by creating a monitoring database system as well as a system based on these data with which to assess the health risk of chemical residues in agricultural products. Meanwhile, a database system is being constructed consisting of information about monitoring and, following this, a demand for convenience has led to the need for an evaluation tool to be constructed with the data processing system. Also, in order to create a systematic and effective tool for the risk assessment of chemical residues in foods and agricultural products, various evaluation models are being developed, both domestically and abroad. Overseas, systems such as Dietary Exposure Evaluation Model: Food Commodity Intake Database and Cumulative and Aggregate Risk Evaluation System are being used; these use the US Environmental Protection Agency as a focus, while the EU has developed Pesticide Residue Intake Model for assessments of pesticide exposure through food intake. Following this, the National Academy of Agricultural Science (NAAS) created the Agricultural Products Risk Assessment System (APRAS) which supports the use and storage of monitoring information and risk assessments. APRAS efficiently manages the monitoring data produced by NAAS and creates an extraction feature included in the database system. Also, the database system in APRAS consists of a monitoring database system held by the NAAS and food consumption database system. Food consumption data is based on Korea National Health and Nutrition Examination Survey. This system is aimed at exposure and risk assessments for chemical residues in agricultural products with regards to different exposure scenarios.

    We present results of the impact of climate change on the agricultural output in Central Asia (CA) since 1991. While profit-maximizing farmers in the market based economies would be expected to change their cropping patterns fairly fast in response to climate change, we do not expect that to happen in the CA region that was for a long time driven by Soviet production plans with a limited room for personal choice. We explore the relationship between the agricultural productivity (measured by the actual output) and the variations in average monthly temperatures during growing seasons and precipitation. The climate data for Central Asia are generated using the Weather Research (WRF) Model for 1985-2012. We make use of data on air temperature on 2m height, C, and total precipitation. The data on the agricultural production comes from the State Statistical Agencies of the three Central Asian countries: Kazakhstan, Kyrgyzstan and Tajikistan. Data on agricultural production for Turkmenistan and Uzbekistan are not available from online government sources. We model the agricultural production as a function of annual realization of weather in a specific region. This economic approach includes converting daily temperature into degree days, which represents heating units. The two key weather variables are a measure of heat (degree days) and total precipitation in the growing season, April 1st to October 30th. Preliminary regression results estimated for Kazakhstan, indicate that degree days during growing season is negatively and total precipitation is positively associated with the agricultural output. Both coefficients are not statistically significant. Further analysis will include data from other countries and also by the region.

    Full Text Available The article analyzes the development of corporate structures in agricultural production, proves the influence of corporate formations on the efficiency of agrarian production. On the basis of the analysis of official information of agro holdings, an assessment was made of the efficiency of their activities and a conclusion was made about the optimal size of their structural subdivisions. The advantages and disadvantages of integrated structures are highlighted, peculiarities of formation of their land relations are determined. Issues of expansion of land masses of agro holdings related to the conclusion of land lease agreements are considered. The association of separate agro-industrial enterprises of various industrial-economic orientation form an independent legal entity - a legal entity. The economic feasibility of the creation and functioning of corporate associations is objective based on obtaining the greatest effect, the essence of which is that the result of the joint corporate activities of economic structures will always be higher compared to the results of the individual work of each of them. Corporate forms of management in agriculture were founded in Ukraine on the basis of the general theoretical model of an open, competitive, multi-faceted agricultural market economy type, aimed at an integrated world economic system. The methodology of construction involves taking into account the world economic trends and the national specificity of the country's agricultural development; it is aimed at finding rational forms of organization of agricultural production, mechanisms for overcoming crisis phenomena, stabilizing the economy and creating conditions for further qualitative and quantitative growth of the agrarian sector of the economy. For many years, leading American co-operators have been distributing concepts and concepts that are perceived and used throughout the world.

    The plant protection by pesticides is increasing in Poland and the established trend rate took into account years 2005-2011. In the period 2002-2004 statistics did not present the full range of crop protection measures authorized for sale and consumption. In contrast the consumption of qualified seeds of basic grains and seed potatoes considerably decreased in Polish agriculture. Only for triticale it was noticed that the trend rate of qualified seeds was increasing. So the farmers should be more widely informed about the advantages of the exchange of seed grain for qualified grains. It will facilitate the quicker implementation of variety progress to agricultural production and adverse changes slowdown agricultural production.

    Radiological contamination of the environment is caused by nuclear activities on the globe: nuclear weapon tests and the Chernobyl accident. The transfer of radionuclides to the organism via ingestion is one of the sources of doses obtained by people. To assess the doses received by humans the intake of isotopes with daily diet was defined. The concentration of radionuclides in foodstuffs was determined. The network of Service for Measurement of Radioactive Contamination systematically controls all kinds of important agricultural products such as milk, meat, vegetables, fruit, cereals and forest products: mushrooms, blueberries etc. Measurement stations involved in food monitoring act within Sanitary-Epidemiological Stations, Veterinary Hygiene Units and Chemical-Agricultural Stations. All activities are co-ordinated by the Central Laboratory for Radiological Protection. The level of activity of caesium isotopes has regularly been monitored in collected samples originating from different administrative districts of Poland. Since 1994 the 134 Cs concentration has been below the detection limit. The activity of 137 Cs has been measured to determine long-term effect of the accident on the contamination of milk, meat and other foodstuffs. (orig.)

    Comprehensive assessment tools are needed that reliably describe environmental impacts of different agricultural systems in order to develop sustainable high yielding agricultural production systems with minimal impacts on the environment. Today, Life Cycle Assessment (LCA) is increasingly used to assess and compare the environmental sustainability of agricultural products from conventional and organic agriculture. However, LCA studies comparing agricultural products from conventional and organic farming systems report a wide variation in the resource efficiency of products from these systems. The studies show that impacts per area farmed land are usually less in organic systems, but related to the quantity produced impacts are often higher. We reviewed 34 comparative LCA studies of organic and conventional agricultural products to analyze whether this result is solely due to the usually lower yields in organic systems or also due to inaccurate modeling within LCA. Comparative LCAs on agricultural products from organic and conventional farming systems often do not adequately differentiate the specific characteristics of the respective farming system in the goal and scope definition and in the inventory analysis. Further, often only a limited number of impact categories are assessed within the impact assessment not allowing for a comprehensive environmental assessment. The most critical points we identified relate to the nitrogen (N) fluxes influencing acidification, eutrophication, and global warming potential, and biodiversity. Usually, N-emissions in LCA inventories of agricultural products are based on model calculations. Modeled N-emissions often do not correspond with the actual amount of N left in the system that may result in potential emissions. Reasons for this may be that N-models are not well adapted to the mode of action of organic fertilizers and that N-emission models often are built on assumptions from conventional agriculture leading to even greater

    Agricultural system models have become important tools to provide predictive and assessment capability to a growing array of decision-makers in the private and public sectors. Despite ongoing research and model improvements, many of the agricultural models today are direct descendants of research investments initially made 30-40 years ago, and many of the major advances in data, information and communication technology (ICT) of the past decade have not been fully exploited. The purpose of this Special Issue of Agricultural Systems is to lay the foundation for the next generation of agricultural systems data, models and knowledge products. The Special Issue is based on a 'NextGen' study led by the Agricultural Model Intercomparison and Improvement Project (AgMIP) with support from the Bill and Melinda Gates Foundation.

    2012-12-01

    Full Text Available Rural areas are often interested by pollution phenomena generated by agricultural activities with a high use of pesticides and/or by anthropic activities, such as industrial plants or illegal waste disposal sites, which may cause even long-range contamination. The risk for human health from the pollutants present in the environment can be quantitatively evaluated by the environmental health risk analysis set out in the Italian Legislative Decree no. 152/2006 (Italian Regulation, 2006. This analysis is the best technical-normative tool to estimate the health risks linked to the pollutants present in the environment but it does not consider the specificity of agricultural soils or the contamination of agricultural products. This study aims to provide this missing technical-normative data by identifying and applying a suitable methodology to evaluate the health risk caused by the ingestion of agricultural products grown in contaminated soils. The risk analysis was applied to two contaminated areas in southern Italy using an innovative methodology based on widely accepted parameters for the determination of polycyclic aromatic hydrocarbons (PAHs soil-plant bio-transfer factor in the case of horticultural crops. In addition, some concentration limits of PAHs in agricultural soils are proposed that may be of help to the competent authorities (health agencies, local authorities in delineating the areas requiring strict health surveillance of the food products cultivated.

    Full Text Available There is relation between the pesticide application and quality of agricultural products. The paper explored the causes and ways to deal with it from the view of agricultural development on the case study of pesticide management and use in a village, Zhejiang Province on the basis of investigation of local government, agriculture technology service station and farmers. The paper pointed out that lack of supervi-sion in the pesticide use and result was only external; the true reasons were high supervise cost and limited service of agriculture technology service station. So the paper drew the conclusions that multifunction agriculture development, superior agriculture produce service system and the change of village committee's role and responsibility were the best answers to the agricultural products safety problem.

    Agricultural phosphorus (P) use is integral to sustainable food production and water quality regulation. Globalization of agricultural systems, changing diets, and increasing biofuel production pose new challenges for managing non-renewable P reserves, particularly in key agricultural producing regions such as the US. We used a detailed model of the US agricultural system to assess the quantity of mineral P fertilizers used to produce food crops, livestock, and biofuels relative to the P ultimately consumed in domestic diets. We also quantified linkages in fertilizer use between the US and its trading partners globally via agricultural trade. Feed and livestock production drove by far the largest demand for P fertilizers in the US (56% of all P use for domestic and imported products). Of the total mineral P inputs to US domestic agriculture in 2007 (1905 Gg P), 28% were retained in agricultural soils as surplus P, 40% were lost through processing and waste prior to consumption in human diets, while 10% were diverted directly to biofuel production. One quarter of P fertilizer in the US was required to produce exports, particularly major food and feed crops (corn, soybean, and wheat) that drove a large net P flux out of the country (338 Gg P) with strongly crop-specific effects on soil P imbalances nationally. However, US meat consumption involved considerable reliance on P fertilizer use in other countries to produce red meat imports linked primarily to soil P surpluses abroad. We show that changes in domestic farm management and consumer waste could together reduce the P fertilizer needed to produce food consumed in the US by half, which is comparable to the P fertilizer reduction attainable by cutting domestic meat consumption (44%). More effective distribution of P use for major crops nationally and greater recycling of all agricultural wastes is critical to using US phosphate rock reserves as efficiently as possible while maintaining export-oriented agriculture.

    2010-12-15

    In this thesis, the feasibility of utilizing energy crops (willow and miscanthus) and agriculture residues (wheat straw and corn stalker) in an anaerobic digestion process for biogas production was evaluated. Potential energy crops and agriculture residues were screened according to their suitability for biogas production. Moreover, pretreatment of these biomasses by using wet explosion method was studied and the effect of the wet explosion process was evaluated based on the increase of (a) sugar release and (b) methane potential when comparing the pretreated biomass and raw biomass. Ensiling of perennial crops was tested as a storage method and pretreatment method for enhancement of the biodegradability of the crops. The efficiency of the silage process was evaluated based on (a) the amount of biomass loss during storage and (b) the effect of the silage on methane potential. Co-digestion of raw and wet explosion pretreated energy crops and agriculture residues with swine manure at various volatile solids (VS) ratio between crop and manure was carried out by batch tests and continuous experiments. The efficiency of the co-digestion experiment was evaluated based on (a) the methane potential in term of ml CH4 produced per g of VS-added and (b) the amount of methane produced per m3 of reactor volume.

    Virtual water trade is often considered a solution for restricted water availability in many regions of the world. Brazil is the world leader in the production and export of various agricultural and livestock products. The country is either a strong net importer or a strong net exporter of these products. The objective of this study is to determine the volume of virtual water contained in agricultural and livestock products imported/exported by Brazil from 1997 to 2012, and to define the water self-sufficiency index of agricultural and livestock products in Brazil. The indexes of water scarcity (WSI), water dependency (WDI) and water self-sufficiency (WSSI) were calculated for each Brazilian state. These indexes and the virtual water balance were calculated following the methodology developed by Chapagain and Hoekstra (2008) and Hoekstra and Hung (2005). The total water exports and imports embedded in agricultural and livestock products were 5.28 × 10 10 and 1.22 × 10 10  Gm 3  yr -1 , respectively, which results in positive virtual water balance of 4.05 × 10 10  Gm 3  yr -1 . Brazil is either a strong net importer or a strong net exporter of agricultural and livestock products among the Mercosur countries. Brazil has a positive virtual water balance of 1.85 × 10 10  Gm 3  yr -1 . The indexes used in this study reveal that Brazil is self-sufficient in food production, except for a few products such as wheat and rice. Horticultural products (tomato, onion, potato, cassava and garlic) make up a unique product group with negative virtual water balance in Brazil. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available The production planning is one of the key managerial decisions in agricultural business, which must be done periodically every year. Correct decision must cover the agriculture demands of planting the crops such as crop rotation restrictions or water resource scarcity, while the decision maker aims to plan the crop design in most profitable way in sense of maximizing the total profit from the crop yield. This decision problem represents the optimization of crop design and can be treated by the me­thods of linear programming which begun to be extensively used in agriculture production planning in USA during 50’s. There is ongoing research of mathematical programming applications in agriculture worldwide, but the results are not easily transferable to other localities due to the specific local restrictions in each country. In Czech Republic the farmers use for production planning mainly their expert knowledge and past experience. However, the mathematical programming approach enables find the true optimal solution of the problem, which especially in the problems with a great number of constraints is not easy to find intuitively. One of the possible barriers for using the general decision support systems (which are based on mathematical programming methods for agriculture production planning in Czech Republic is its expensiveness. The small farmer can not afford to buy the expensive software or to employ a mathematical programming specialist. The aim of this paper is to present a user friendly linear programming model of the typical agricultural production planning problem in Czech Republic which can be solved via software tools commonly available in any farm (e.g. EXCEL. The linear programming model covering the restrictions on total costs, crop rotation, thresholds for the total area sowed by particular crops, total amount of manure and the need of feed crops is developed. The model is applied in real-world problem of Czech agriculture

  20. Application of solar energy to agricultural production processes. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1986-01-01

    The presentations in this report were a result of research and development projects funded and managed by Interagency Agreements between the Department of Energy and the Department of Agriculture. The performing institutions were selected on the basis of peer reviews of invited and/or unsolicited proposals. During the time period covered, approximately 9 years, hundreds of technical reports and presentations have been made. The audience for these reports has included other researchers, manufacturers, sales people, contractors and end users of the information. As a result, thousands of installations have been made. Some of these have been highly successful, while others have been less successful, and some have failed. Nevertheless, these projects have shown areas where solar energy can be profitably applied to replace non-renewable forms of energy for agricultural production; areas where the use of solar energy is marginal; and areas where the use of solar energy is not profitable with current costs of non-renewable energy.

    2016-01-01

    We conducted an exploratory investigation of factors influencing the adoption of radio frequency identification (RFID) methods in the agricultural product distribution industry. Through a literature review and field research, and based on the technology-organization-environment (TOE) theoretical framework, this paper analyzes factors influencing RFID adoption in the agricultural product distribution industry in reference to three contexts: technological, organizational, and environmental contexts. An empirical analysis of the TOE framework was conducted by applying structural equation modeling based on actual data from a questionnaire survey on the agricultural product distribution industry in China. The results show that employee resistance and uncertainty are not supported by the model. Technological compatibility, perceived effectiveness, organizational size, upper management support, trust between enterprises, technical knowledge, competitive pressure and support from the Chinese government, which are supported by the model, have significantly positive effects on RFID adoption. Meanwhile, organizational size has the strongest positive effect, while competitive pressure levels have the smallest effect. Technological complexities and costs have significantly negative effects on RFID adoption, with cost being the most significantly negative influencing factor. These research findings will afford enterprises in the agricultural products supply chain with a stronger understanding of the factors that influence RFID adoption in the agricultural product distribution industry. In addition, these findings will help enterprises remain aware of how these factors affect RFID adoption and will thus help enterprises make more accurate and rational decisions by promoting RFID application in the agricultural product distribution industry.

    Full Text Available Filter treatment may be a viable means for removing the nitrate (NO3−, phosphate (PO43−, and pesticides discharged with agricultural drainage waters that cause adverse environmental impacts within the U.S. on local, regional, and national scales. Laboratory batch test screening for agricultural drainage water treatment potential was conducted on 58 industrial product/byproduct filter materials grouped into six categories: (1 high carbon content media; (2 high iron content media; (3 high aluminum content media; (4 surfactant modified clay/zeolite; (5 coal combustion residuals; and (6 spent foundry sands. Based on a percent contaminant removal criteria of 75% or greater, seven industrial products/byproducts were found to meet this standard for NO3− alone, 44 met this standard for PO43−, and 25 met this standard for the chlorinated triazine herbicide, atrazine. Using a 50% or greater contaminant removal criteria, five of the industrial product/byproduct filter materials exhibited potential for removing NO3−, PO43−, and atrazine together; eight showed capability for combined NO3− and PO43− removal; 21 showed capability for combined PO43− and atrazine removal; and nine showed capability for combined NO3− and atrazine removal. The results of this study delineated some potential industrial product/byproduct filter materials for drainage water treatment; however, a complete feasibility evaluation for drainage water treatment of any of these filter materials will require much more extensive testing.

    The problem of sustainability is a topic that since the end of the XX century has been worrying more the different sectors of society; becoming one of the topics of greatest interest for managers, consumers, academics and investigators that conform the different agricultural food chains of the world. This paper presents from the general systems theory point of view some elements of critical reflection, approaching the problem of sustainability from the complexity of agricultural production systems, beginning with the original philosophical conception of agricultural and ending by outlining some considerations that should be kept in mind for the development of scientific and technological advances concordant with the agricultural food chain needs of the XX century; which permit an orientation of not only work by profession is who lead the processes of animal and vegetable production, but also creates a sense of pertinence in all of the participants in the chain, highlighting the importance of studying by means of systemic thought, agronomy and animal science, as disciplines that approach to complexities of agriculture which is the angular stone of civilization, such as we know it at the moment

    Kander, Astrid; Warde, Paul

    2011-01-01

    This article explores the proposition that a reason for high agricultural productivity in the early nineteenth century was relatively high energy availability from draught animals. The article is based on the collection of extensive new data indicating different trends in draught power availability and the efficiency of its use in different countries of Europe. This article shows that the proposition does not hold, and demonstrates that, although towards the end of the nineteenth century England had relatively high numbers of draught animals per agricultural worker, it also had low number of workers and animals per hectare, indicating the high efficiency of muscle power, rather than an abundance of such power. The higher efficiency was related to a specialization on less labour-intensive farming and a preference for horses over oxen.

    The consumption of fresh-cut agricultural produce in Korea has been growing. The browning of fresh-cut vegetables that occurs during storage and foreign substances such as worms and slugs are some of the main causes of consumers' concerns with respect to safety and hygiene. The purpose of this study is to develop an on-line system for evaluating quality of agricultural products using hyperspectral imaging technology. The online evaluation system with single visible-near infrared hyperspectral camera in the range of 400 nm to 1000 nm that can assess quality of both surfaces of agricultural products such as fresh-cut lettuce was designed. Algorithms to detect browning surface were developed for this system. The optimal wavebands for discriminating between browning and sound lettuce as well as between browning lettuce and the conveyor belt were investigated using the correlation analysis and the one-way analysis of variance method. The imaging algorithms to discriminate the browning lettuces were developed using the optimal wavebands. The ratio image (RI) algorithm of the 533 nm and 697 nm images (RI533/697) for abaxial surface lettuce and the ratio image algorithm (RI533/697) and subtraction image (SI) algorithm (SI538-697) for adaxial surface lettuce had the highest classification accuracies. The classification accuracy of browning and sound lettuce was 100.0% and above 96.0%, respectively, for the both surfaces. The overall results show that the online hyperspectral imaging system could potentially be used to assess quality of agricultural products.

    2015-01-01

    Livestock farming is the world’s largest land use sector and utilizes around 60% of the global biomass harvest. Over the coming decades, climate change will affect the natural resource base of livestock production, especially the productivity of rangeland and feed crops. Based on a comprehensive impact modeling chain, we assess implications of different climate projections for agricultural production costs and land use change and explore the effectiveness of livestock system transitions as an adaptation strategy. Simulated climate impacts on crop yields and rangeland productivity generate adaptation costs amounting to 3% of total agricultural production costs in 2045 (i.e. 145 billion US$). Shifts in livestock production towards mixed crop-livestock systems represent a resource- and cost-efficient adaptation option, reducing agricultural adaptation costs to 0.3% of total production costs and simultaneously abating deforestation by about 76 million ha globally. The relatively positive climate impacts on grass yields compared with crop yields favor grazing systems inter alia in South Asia and North America. Incomplete transitions in production systems already have a strong adaptive and cost reducing effect: a 50% shift to mixed systems lowers agricultural adaptation costs to 0.8%. General responses of production costs to system transitions are robust across different global climate and crop models as well as regarding assumptions on CO 2 fertilization, but simulated values show a large variation. In the face of these uncertainties, public policy support for transforming livestock production systems provides an important lever to improve agricultural resource management and lower adaptation costs, possibly even contributing to emission reduction.

    2017-10-01

    Nowadays bio-based composite materials have been used in rising amounts and demanded widely in industrial uses, as they provide cost reduction and weight loss in the end use products. Agricultural cellulose based wastes can be a good alternative to synthetic fibers and can be used in natural fiber reinforced composite production, as there is a huge (more than 40 million tons) potential for natural cellulose production from agricultural wastes. Okra is one of the most grown vegetables around the world with stems left on the fields after harvest. When the similarity of mechanical properties of okra fibers with traditional bast fibers (flax, kenaf, hemp) are considered, from an economical and an environmental point of view this research emphasizes the potential of agricultural biomass for natural fiber production. In this study, okra stem wastes used for natural cellulosic fiber production and treated with 10% NaOH at 60°C for 10, 20, 30 and 40 minutes. By alkali treatment, decrease in fiber diameter and weight, and increase in tensile strength and elongation % have been observed. Nonwoven production has been done from both the fibers with and without surface treatments. Thermal conductivity properties of both nonwovens have been investigated.

    Production of renewable energy from biomass has been promoted as means to improve greenhouse gas balance in energy production, improve energy security, and provide jobs and income. However, uncertainties remain as to how the agriculture and forest sectors might jointly respond to increased demand for bioelectricity feedstocks and the potential environmental consequences of increased biomass production. We use an economic model to examine how the agriculture and forest sectors might combine to respond to increased demands for bioelectricity under simulated future national-level renewable electricity standards. Both sectors are projected to contribute biomass, although energy crops, like switchgrass, produced on agriculture land are projected to be the primary feedstocks. At the highest targets for bioelectricity production, we project increased conversion of forest to agriculture land in support of agriculture biomass production. Although land conversion takes place in response to renewable electricity mandates, we project only minor increases in forest and agriculture emissions. Similarly, crop prices were projected to generally be stable in the face of increased bioelectricity demand and displacement of traditional agriculture crops. - Highlights: ► We model the response of forest and agriculture to increased bioelectricity demand. ► The agriculture sector, through energy crop production, is the key biomass provider. ► Increased land exchange is projected for the highest bioelectricity demands. ► Land exchange from forest to agriculture yield the greatest changes in GHG flux. ► Agriculture and forestry must be accounted for when considering bioenergy policy

    The North China Plain (NCP) and US High Plains (USHP) are considered bread baskets of China and the US. The objective of this study was to compare agricultural production during the past 30 yr in both regions to assess impacts of different management options. The NCP and USHP are similar in terms of climate (mean annual precipitation: NCP, 570 mm; USHP, 520 mm) with mostly summer precipitation, and wheat and corn (maize) as the dominant crops. While single cropping is dominant in the USHP with summer crops coincident with seasonal precipitation, double cropping is prevalent in the NCP with summer corn coinciding with precipitation and winter wheat relying on irrigation. During the past 30 yr (1980 - 2008) in the NCP, crop yield has increased by a factor of 2.8 (2,200 - 6,200 kg/ha), grain production by a factor of 2.6 (23 - 59 million tons), chemical fertilizer application by a factor of 5.1 (68 - 350 kg/ha). During the same time period in the USHP, grain yield increased by a factor of 1.8 (2,800 - 5,000 kg/ha), crop production by a factor of 1.4 (48 - 68 million tons), chemical N fertilizer application by a factor of 1.2 (64 - 74 kg/ha). The spatial averages mask large scale local variability with grain yield in Luancheng county in the NCP for double cropped wheat and corn rising from 8,000 kg/ha in 1980 to ~16,000 kg/ha in 2008. The comparison between the two regions leads to the question of whether agricultural production in the NCP would be more sustainable with a single corn crop with a longer growing season more aligned with precipitation distribution. Increases in fertilizer application in the NCP greatly exceed crop yield increases, suggesting that much of this fertilizer may be leached to the environment, resulting in contamination. The comparisons between these two regions provide valuable insights that should be considered to move toward more sustainable management in terms of crop productivity and environmental impacts.

    The irradiation of food and agriculture products have been used for several goals. That are: disinsectization, disinfection, sprout inhibition and retardation of mattering. In the frames of the national programme on the application of irradiation for food preservation and hygienization an experimental plant for electron beam processing has been established in INCT (Institute of Nuclear Chemistry and Technology). The pilot plant is equipped with a small research accelerator Pilot (10 MeV, 1 kW) and and industrial unit Elektronika (10 MeV, 10 kW). This allows both laboratory and full technological scale testing of the elaborated process to be conducted. The industrial unit is being equipped with e-/X conversion target, for high density products irradiation. On the basis of the research there were performed at different scientific institutions in Poland, health authorities have issued permissions for permanent treatment of spices, garlic, onions and temporary permissions for mushrooms, and potatoes. Dosimetric methods have been elaborated for the routine use at the plant. In the INCT laboratory methods for the control of e-/X treated food have been established. (author)

    Climate change threatens the ability of agriculture and forestry to meet growing global demands for food, fibre and wood products. Information gathered from genotype-by-environment interactions (G × E), which demonstrate intraspecific variation in phenotypic plasticity (the ability of a genotype to alter its phenotype in response to environmental change), may prove important for bolstering agricultural and forest productivity under climate change. Nonetheless, very few studies have explicitly quantified genotype plasticity-productivity relationships in agriculture or forestry. Here, we conceptualize the importance of intraspecific variation in agricultural and forest species plasticity, and discuss the physiological and genetic factors contributing to intraspecific variation in phenotypic plasticity. Our discussion highlights the need for an integrated understanding of the mechanisms of G × E, more extensive assessments of genotypic responses to climate change under field conditions, and explicit testing of genotype plasticity-productivity relationships. Ultimately, further investigation of intraspecific variation in phenotypic plasticity in agriculture and forestry may prove important for identifying genotypes capable of increasing or sustaining productivity under more extreme climatic conditions. © 2014 John Wiley & Sons Ltd.

    Full Text Available The assessment of Total Factor Productivity (TFP, i.e. inclusion of all factors of production seems to be an easy task. However, its calculation can meet with some difficulties. The calculation of inputs is complicated as different factors of production, which are processes to outputs, has to be transformed to a common factor. The aim of the paper was to analyse relations of efficiency of factors of production measured by factor productivity based on economic profit and returns (profitability of enterprise measured by the most synthetic profitability indicator (Return on Assets, ROA. A partial aim was to consider risk analysed through ratio of cost to capital (Weighted Average Cost of Capital – WACC performed in the sample on agricultural enterprises in 2004–2008. The database used for the research consisted of 622 agricultural enterprises. The methodology of calculation was based on an approach according to Neumaierová and Neumaier (2002 considering the economic profit. This methodology suits well to conditions of Czech financial statements (a balance sheets and a profit and loss statement. The TFP assessment was connected to the return on assets and the correlation analysis revealed dependences of calculated indicators. The paper is a part of the MSM 6007665806 research project.

  1. Rational allocation of agricultural production in the region

    2015-05-01

    Full Text Available The paper proposes an original approach to determining the optimal allocation of agricultural production in the region; the approach includes the methodological substantiation of the necessity to differentiate consumers when addressing food security issues in the region. It was proposed to allocate three levels: level 1 – the provision of food to socially vulnerable layers, level 2 – the provision with food at the subsistence level, and level 3 – the provision of the total population of the region with food. A preliminary forecast was made for each municipality; it analyzed possible changes in the number of the socially vulnerable up to 2020; in accordance with medical standards and norms of the subsistence level the volumes of food were calculated, which in turn were compared with the actual production output. The difference between the actual volume and the volume of evidence-based requirements represented the very increase in the volume of production, the achievement of which requires certain investments on the basis of capital-output ratio. After that the regional market was divided into three sub-regional markets depending on distance, number of consumers and suppliers. This allowed us to calculate the amount of transport costs based on the type and lot size of the transported product, taking into account the distance to each sub-market. As a criterion of transportation expediency we took into account the share of transport costs in the price of the product not exceeding 30%. Otherwise, it is required to concentrate the production in order to increase the lot transported or to carry out a deeper processing of the product. The proposed methodology served as the basis for choosing the most effective option of spatial location of agricultural production

    A soil-water slurry experiment was conducted to study the potentials of N2O production and reduction in denitrification of agricultural and beech forest soils in Denmark. The effects of nitrate and ammonium additions on denitrification were also investigated. The forest soil showed a higher denitrification potential than the agricultural soil. However, N2O reduction potential of the agricultural soil was higher than the beech forest soil, shown by the ratio of N2O/N2 approximately 0.11 and 3.65 in the agricultural and the beech forest soils, respectively. Both nitrate and ammonium additions stimulated the N2O production in the two soils, but reduced the N2O reduction rates in the agricultural soil slurries. In contrast to the effect on the agricultural soil, nitrate reduced the N2O reduction rate in the beech forest soil, while ammonium showed a stimulating effect on the N2O reduction activity. After one week incubation, all of the N2O produced was reduced to N2 in the agricultural soil when nitrate was still present. Nitrous oxide reduction in the beech forest soil occurred only when nitrate almost disappeared. The different nitrate inhibitory effect on the N2O reduction activity in the two soils was due to the difference in soil pH. Inhibition of nitrate on N2O reduction was significant under acidic condition. Consequently, soil could serve as a sink of atmospheric N2O under the conditions of anaerobic, pH near neutral and low nitrate content.

    The new aspect of agrification is the production of alternative products, which can replace fossil sources. This substitution is necessary in order to replace hazardous materials and to find a solution for the problem of depletion of conventional energy sources and basic materials. Attention is paid to some developments in Germany: agricultural products for the production of energy, and new industrial applications for vegetable filaments. With regard to energy production from agricultrual products one should distinguish between (a) solid energy sources (biomass), f.e. straw, fast-growing wood, elephant's grass, hay and rapeseed, and (b) fluid and gaseous energy sources, f.e. purified and partly refined rapeseed oil, rapeseed oil methyl-ester (RME), ethanol from sugar beet, methanol from straw and hydrogen from straw and/or elephant's grass. 4 figs., 7 refs

    Since the end of World War II, global agriculture has undergone a period of rapid intensification achieved through a combination of increased applications of chemical fertilizers, pesticides, and herbicides, the implementation of best management practice techniques, mechanization, irrigation, and more recently, through the use of optimized seed varieties and genetic engineering. However, not all crops and not all regions of the world have realized the same improvements in agricultural intensity. In this study we examine both the magnitude and spatial variation of new agricultural production potential from closing of 'yield gaps' for 20 ethanol and biodiesel feedstock crops. With biofuels coming under increasing pressure to slow or eliminate indirect land-use conversion, the use of targeted intensification via established agricultural practices might offer an alternative for continued growth. We find that by closing the 50th percentile production gap-essentially improving global yields to median levels-the 20 crops in this study could provide approximately 112.5 billion liters of new ethanol and 8.5 billion liters of new biodiesel production. This study is intended to be an important new resource for scientists and policymakers alike-helping to more accurately understand spatial variation of yield and agricultural intensification potential, as well as employing these data to better utilize existing infrastructure and optimize the distribution of development and aid capital.

  9. Agriculture in the climate change negotiations; ensuring that food production is not threatened.

    With the human population predicted to reach nine billion by 2050, demand for food is predicted to more than double over this time period, a trend which will lead to increased greenhouse gas (GHG) emissions from agriculture. Furthermore, expansion in food production is predicted to occur primarily in the developing world, where adaptation to climate change may be more difficult and opportunities to mitigate emissions limited. In the establishment of the United Nations Framework Convention on Climate Change (UNFCCC), 'ensuring that food production is not threatened' is explicitly mentioned in the objective of the Convention. However, the focus of negotiations under the Convention has largely been on reducing GHG emissions from energy, and industrial activities and realizing the potential of forestry as a carbon sink. There has been little attention by the UNFCCC to address the challenges and opportunities for the agriculture sector. Since 2006, concerted efforts have been made to raise the prominence of agriculture within the negotiations. The most recent The Intergovernmental Panel on Climate Change report and 'The Emissions Gap Report' by the UNEP highlighted the significant mitigation potential of agriculture, which can help contribute towards keeping global temperature rises below the 2°C limit agreed in Cancun. Agriculture has to be a part of the solution to address climate change, but this will also require a focus on how agriculture systems can adapt to climate change in order to continue to increase food output. However, to effectively realize this potential, systematic and dedicated discussion and decisions within the UNFCCC are needed. UNFCCC discussions on a specific agriculture agenda item started in 2012, but are currently inconclusive. However, Parties are generally in agreement on the importance of agriculture in contributing to food security and employment as well as the need to improve understanding of agriculture and how it can contribute to

    Full Text Available Issues and concerns for food safety, agro-processing, and the environmental and ecological impact of food production have been attracted many research interests. Traceability and logistics management of fresh agricultural products is faced with the technological challenges including food product label and identification, activity/process characterization, information systems for the supply chain, i.e., from farm to table. Application of information technologies for food processing and logistics industry in the fields of smart packaging and materials, automation and control technology, standards and their application scenarios, and production management principles were wildly studied. A collaborative research project for the supply and logistics of fresh agricultural products in Tianjin was performed. System analysis for the logistics management information system is studied. The model-driven business transformation, an approach uses formal models to explicitly define the structure and behavior of a business, is applied for the review and analysis process. Requirements for the logistic management solutions are proposed. Development of this research is crucial for the solution integration of supply and logistic management information system for fresh agricultural products.

    2016-10-01

    Full Text Available Japan's agriculture provides only a part from the population's needs, in caloric terms Japan must impute 60% of foods. Arable land are few, but are worked very performant, rice being the main crop together with cotton, citrus, sugarcane, wheat, potato, soybean, sugar beet, other vegetables. Widely is practiced sericulture and fisheries, Japan being one of the leading producers of silk from the world and having over 600 ports specialized for fishing. Japanese agriculture has remained behind the industry and services, this trend being manifested after the very high economic growth from 1960-1970. The main focus of the movements from the Japanese cooperative system is represented by the creation of large specialized farms through the replacing of the traditional ones. The most important task of agricultural cooperatives from Japan is meeting the consumption needs of its members. Integrated leadership of Japanese cooperatives of farmers act at all levels, primary, at prefecture level and at national level. Contractual relationships play a decisive role in the integration of Japanese farmers. In Japan there are about 840 agricultural cooperatives very well organized with a balanced planning and efficiently conducted, agricultural cooperative MIKABI being the most developed, mainly focused on the production of mandarins. In Japan there are three large distribution centers of agricultural products, 29 distribution markets controlled by the prefecture and 1,000 local markets. Organization of cooperatives is the pyramid system on three levels: local, prefecture and national (National Federation of Agricultural Cooperatives.

    The methodology of integrated assessment of quality and safety of agricultural products, approbated by the example of indicators of wheat grain in relation to the provision of consumer properties of bakery products, was developed. Determination of the level of quality of the raw ingredients will allow direct using of agricultural raw materials for food production, taking into account ongoing technology, types of products, and, respectively, rational use of resource potential of the agricultural sector. The mathematical tool of the proposed method is a fuzzy set theory. The fuzzy classifier to evaluate the properties of the grain is formed. The set of six indicators normalized by the national standard is determined; values are ordered and represented by linguistic variables with a trapeziform membership function; the rules for calculation of membership functions are presented. Specific criteria values for individual indicators in shaping the quality of the finished products are considered. For one of the samples of wheat grain values of membership; functions of the linguistic variable "level" for all indicators and the linguistic variable "level of quality" were calculated. It is established that the studied sample of grain obtains the 2 (average) level of quality. Accordingly, it can be recommended for the production of bakery products with higher requirements for the structural-mechanical properties bakery and puff pastry products hearth bread and flour confectionery products of the group of hard dough cookies and crackers

  13. High-resolution model for estimating the economic and policy implications of agricultural soil salinization in California

    Welle, Paul D.; Mauter, Meagan S.

    2017-09-01

    This work introduces a generalizable approach for estimating the field-scale agricultural yield losses due to soil salinization. When integrated with regional data on crop yields and prices, this model provides high-resolution estimates for revenue losses over large agricultural regions. These methods account for the uncertainty inherent in model inputs derived from satellites, experimental field data, and interpreted model results. We apply this method to estimate the effect of soil salinity on agricultural outputs in California, performing the analysis with both high-resolution (i.e. field scale) and low-resolution (i.e. county-scale) data sources to highlight the importance of spatial resolution in agricultural analysis. We estimate that soil salinity reduced agricultural revenues by 3.7 billion (1.7-7.0 billion) in 2014, amounting to 8.0 million tons of lost production relative to soil salinities below the crop-specific thresholds. When using low-resolution data sources, we find that the costs of salinization are underestimated by a factor of three. These results highlight the need for high-resolution data in agro-environmental assessment as well as the challenges associated with their integration.

  14. The Role of Governance in Agricultural Expansion and Intensification: a Global Study of Arable Agriculture

    2011-06-01

    Full Text Available In this research we studied empirical relationships between agricultural production dynamics and six quantitative World Bank governance indicators for 173 countries between 1975 and 2007. It is hypothesized that in countries with lower quality of governance, agricultural production increases are more likely to be achieved by area expansions than by increases in yields. We distinguished four groups of countries: those with both area and yield increases; those with increasing yields but decreasing area; those with decreasing yields but a growing area; and those with both declines in yields and area. We analyzed differences between these four groups, and also analyzed governance-production relationships within these groups. On average, quality of governance is low in countries with both area and yield increases and high in countries with increasing yields but decreasing area. Countries with declining yields were too few in number to allow for quantitative analyses. The analysis of governance-production relationships within the four groups suggests that countries with a lower quality of governance are more inclined to achieve production increases by expanding agricultural area rather than increasing yields. Additional explanatory value of governance indicators to agricultural production dynamics is generally small, but nevertheless significant in most cases. Our results suggest that, in order for agricultural production to increase without excessive expansions of agricultural area, governance issues should be resolved.

    Full Text Available Aspergillus species are able to produce a range of mycotoxins, includ­ing e.g. aflatoxins, ochratoxins, fumonisins and patulin. Aflatoxins are mainly produced by members of Aspergillus section Flavi, and they contaminate various agricultural products in several parts of the world. Several recent reports have indicated that aflatoxin-producing fungi and consequently aflatoxin contamination occur in agricultural commodities in a number of European countries which have not been faced with this problem before. Indeed, recent surveys have clarified that concentrations of aflatoxins in maize products and milk has been exceeding the EU limit in several regions of Central Europe including Serbia, Slovenia, Croatia, Northern Italy and Romania. However, aflatoxin contamination and aflatoxin-producing Aspergillus species have not been identified yet in maize in Hungary. We examined the presence of potential aflatoxin-producing Aspergilli in maize samples collected in southern parts of Hungary. Several A. flavus isolates were identified, and pre­liminary results indicated that some of the isolates were able to produce aflatoxins. Con­tamination of other agricultural products with aflatoxins can also pose problems in Central Europe due to global warming. Ochratoxin contamination of grapes and grape-derived products is usually caused by black Aspergilli, especially by A. carbonarius and A. niger, although these species have been rare in Central European vineyards due to climatic fac­tors. Ochratoxin contamination of other agricultural products including spices and cereals was also observed in the region. Besides, ochratoxin producing Aspergilli are frequently isolated from imported products including coffee beans, dried fruits and spices, and ochra­toxin contamination of these samples was also observed. Fumonisins are produced mainly by Fusarium species, and by the recently identified producers Aspergillus niger and A. awamori. We examined fumonisin

    A high performance liquid chromatography-tandem mass spectrometry method (HPLC-MS/MS) was developed for the analysis of amitrole residues in agricultural products. The samples were extracted by 25% acetone for wheat, fish, pork and liver samples, 1% acetic acid-25% acetone for maize and peanut samples, 1% acetic acid solution for honeysuckle, the powder of ginger, the powder of bunge prickly ash and tea leaves samples, 1% acetic acid solution-dichloromethane for apple, pineapple, spinach, carrot, perilla leaves samples, respectively, followed by liquid-liquid extraction with dichloromethane. The samples were then cleaned up by PCX or Envi-Carb solid-phase extraction cartridge. The amitrole was determined and confirmed by HPLC-MS/MS. The results showed a linear relationship in the range of 0.005 -0.1 mg/kg for amitrole. The correlation coefficient was 0.999 7. The average recoveries of amitrole in wheat, maize, peanut, pineapple, apple, carrot, spinach, pork, the powder of ginger, the powder of bunge prickly ash, perilla, liver, fish, honeysuckle and tea were 67.5% - 98.1%. The relative standard deviations (RSDs) were 1.0% - 9.8%. The limits of quantitation were 10 microg/kg for wheat, maize, peanut, pineapple, apple, carrot, spinach, pork, perilla, liver, fish, honeysuckle and 20 microg/kg for the powder of bunge prickly ash, the powder of ginger and tea, respectively. The method is simple, sensitive and accurate.

  20. DID THE 2004 CAP REFORM AFFECT PRODUCTION PRACTICES OF CEREALS? INSIGHTS FROM THE AGRICULTURAL INPUT SUPPLIERS

    Directory of Open Access Journals (Sweden)

    Theodoros MARKOPOULOS

    2015-10-01

    Full Text Available The Mid-term review of the Common Agricultural Policy in 2003/2004 has strengthened the multifunctional role of agriculture by implementing “decoupling”, “modulation” and “cross-compliance” and created a number of significant changes in agricultural production in all EU member states. Specifically, the reform shifted emphasis away from commodity support towards environmental contracts, diversified production practices and rural development. In the case of cereals, a full decoupling was applied in subsidies and integration through rights in the Single Payment Scheme, except rice, which was one of the few crop cases in which part of the subsidy remained coupled, particular in countries with significant production like Greece. Within this context, the present study aims to analyze the impact that the reformed CAP measures had on agricultural production and more specifically variations in production diversification. The novelty of this study is that instead of focusing on the producers, it targeted the agricultural input stores, so as to get better insights of the CAP reform impacts on a larger scale of the regional economy. Accordingly, primary data were collected through personal interviews (structured questionnaire from 209 owners of agricultural input stores in the region of Anatoliki Makedonia and Thraki and were analyzed through multivariate data analysis. The results identify important antecedents for the regional economy and the viability of agricultural input stores, which include factors of the reformed CAP, environmental issues, financial measures and CAP effects on cereal production and marketing.

    Full Text Available To make better the life, it is required safety foods for health. The health foods can be satisfied by organic farming. Organic farming is farming system based on biomass recycling or eliminating the use of materials as a synthetic agrochemical inputs. To determine whether the result of rice called as an organic product needs to be certified by the Organic Certification Board (OCB. According to the Indonesian National Standard (INS 6729: 2013, organic farming systems (OFS are not only limited to not use material agrochemical synthetic, but must meet the requirements of OFS in rice production ranging from cultivating, handling, storage, processing, transportation, labeling, marketing, production facilities and other materials that are allowed start on farm to off farm should be separated from conventional agriculture. The farm is just a negate the use of synthetic agrochemicals without regard to the cultivation process and the system of post-harvest organic results are said to be premium food which is not as organic food, because organic food is food produced from OFS by applying processing practices to preserve the ecosystem of sustainable, control of weeds, pests, diseases, selection and crop rotation, water management, land preparation and planting and the use of biological materials. Thus the system of organic agriculture is a holistic management system to improve and develop the agro-ecosystem health, including biodiversity, biological cycles and soil biological activity. The first step that must be done is the conversion of land for food crops from anorganic to organic farming for 2 years did not get the requisite amount of agrochemical applied to the soil for annual crop and 3 years for perennial crops. If agriculture in paddy soil can control the conventional farms into OFS, then the resulting rice is as an organic product.

    Ecosystem services are faced with multiple stress from complex driving factors, such as climate change and human interventions. The Heihe River Basin (HRB), as the second largest inland river basin in China, is a typical semi-arid and arid region with fragile and sensitive ecological environment. For the past decades, agricultural production activities in the basin has affected ecosystem services in different degrees, leading to complex relations among "water-land-climate-ecology-human", in which hydrological process and water resource management is the key. In this context, managing trade-offs among water uses in the river basin to sustain multiple ecosystem services is crucial for healthy ecosystem and sustainable socioeconomic development. In this study, we analyze the trade-offs between different water uses in agricultural production and key ecosystem services in the HRB by applying production frontier analysis, with the aim to explore the potential for managing them. This method traces out joint production frontiers showing the combinations of ecosystem services and agricultural production that can be generated in a given area, and it deals with the economic problem of the allocation of scarce water resources under presumed objective, which aims to highlight synergies and reduce trade-offs between alternative water uses. Thus, management schemes that targets to both sustain agricultural production and increase the provision of key ecosystem services have to consider not only the technological or biological nature of interrelationships, but also the economic interdependencies among them.

    Poultry and agriculture industry has a great role in the development of food sector in Pakistan. Whole of the Lysine required for poultry feed is imported to fulfil the desired dietary needs. Present study was designed to utilize different agricultural by-products like molasses, wheat bran, rice polishing and corn steep liquor. Different Physico-Chemical parameters were optimized to have hyper-production of Lysine through fermentation by using Brevibacterium flavum as a fermentative agent. From wheat bran, rice polishing and molasses (as best carbon source), significantly high concentrations of lysine (10.4 g/L) after 72h of incubation was observed with molasses (4 percentage) with 3 percentage (v/v) inoculum size at 30 degree C and pH 7. Among different nitrogen sources, 0.25 percentage (NH/sub 4/)2SO/sub 4/ showed significantly (P< 0.05) high yield of Lysine (16.89 g/L). Addition of different optimum levels of ionic salts; 4 percentage CaCO/sub 3/, 0.4 percentage MgSO/sub 4/.7H/sub 2/O, 0.1 percentage NaCl and 0.2 percentage KH/sub 2/PO/sub 4/ gave significantly (P< 0.05) higher quantity of Lysine 19.01 g/L. Inclusion of 0.6 percentage corn steep liquor and 0.4 mg/100mL biotin significantly (P< 0.05) raised the Lysine from 19.4 g/L - 19.45 g/L. The presence of Lysine in fermented broth was detected by TLC. Thus a cheap and practical bioprocess of Lysine production was concluded, that can be exploited commercially to save foreign exchange.

    "Genetically modified" (GM) or "biotech" crops have been the most rapidly adopted agricultural technology in recent years. The development of a GM crop encompasses trait identification, gene isolation, plant cell transformation, plant regeneration, efficacy evaluation, commercial event identification, safety evaluation, and finally commercial authorization. This is a lengthy, complex, and resource-intensive process. Crops produced through biotechnology are the most highly studied food or food component consumed. Before commercialization, these products are shown to be as safe as conventional crops with respect to feed, food, and the environment. This paper describes this global process and the various analytical tests that must accompany the product during the course of development, throughout its market life, and beyond.

    Renewable energy production has been expanding at a rapid pace. New advances in cellulosic ethanol technologies have the potential to displace the use of petroleum as a transportation fuel, and could have significant effects on both the agricultural economy and the environment. In this letter, the effects of falling cellulosic ethanol production costs on the mix of ethanol feedstocks employed and on the US agricultural economy are examined. Results indicate that, as expected, cellulosic ethanol production increases by a substantial amount as conversion technology improves. Corn production increases initially following the introduction of cellulosic technology, because producers enjoy new revenue from sales of corn stover. After cellulosic ethanol production becomes substantially cheaper, however, acres are shifted from corn production to all other agricultural commodities. Essentially, this new technology could facilitate the exploitation of a previously under-employed resource (corn stover), resulting in an improvement in overall welfare. In the most optimistic scenario considered, 68% of US ethanol is derived from cellulosic sources, coarse grain production is reduced by about 2%, and the prices of all food commodities are reduced modestly.

    Full Text Available The current Amazon landscape consists of heterogeneous mosaics formed by interactions between the original forest and productive activities. Recognizing and quantifying the characteristics of these landscapes is essential for understanding agricultural production chains, assessing the impact of policies, and in planning future actions. Our main objective was to construct the regionalization of agricultural production for Rondônia State (Brazilian Amazon at the municipal level. We adopted a decision tree approach, using land use maps derived from remote sensing data (PRODES and TerraClass combined with socioeconomic data. The decision trees allowed us to allocate municipalities to one of five agricultural production systems: (i coexistence of livestock production and intensive agriculture; (ii semi-intensive beef and milk production; (iii semi-intensive beef production; (iv intensive beef and milk production, and; (v intensive beef production. These production systems are, respectively, linked to mechanized agriculture (i, traditional cattle farming with low management, with (ii or without (iii a significant presence of dairy farming, and to more intensive livestock farming with (iv or without (v a significant presence of dairy farming. The municipalities and associated production systems were then characterized using a wide variety of quantitative metrics grouped into four dimensions: (i agricultural production; (ii economics; (iii territorial configuration, and; (iv social characteristics. We found that production systems linked to mechanized agriculture predominate in the south of the state, while intensive farming is mainly found in the center of the state. Semi-intensive livestock farming is mainly located close to the southwest frontier and in the north of the state, where human occupation of the territory is not fully consolidated. This distributional pattern reflects the origins of the agricultural production system of Rond

    Increases in the severity and frequency of drought in a warming climate may negatively impact agricultural production and food security. Unlike previous studies that have estimated agricultural impacts of climate condition using single-crop yield distributions, we develop a multivariate probabilistic model that uses projected climatic conditions (e.g., precipitation amount or soil moisture) throughout a growing season to estimate the probability distribution of crop yields. We demonstrate the model by an analysis of the historical period 1980-2012, including the Millennium Drought in Australia (2001-2009). We find that precipitation and soil moisture deficit in dry growing seasons reduced the average annual yield of the five largest crops in Australia (wheat, broad beans, canola, lupine, and barley) by 25-45% relative to the wet growing seasons. Our model can thus produce region- and crop-specific agricultural sensitivities to climate conditions and variability. Probabilistic estimates of yield may help decision-makers in government and business to quantitatively assess the vulnerability of agriculture to climate variations. We develop a multivariate probabilistic model that uses precipitation to estimate the probability distribution of crop yields. The proposed model shows how the probability distribution of crop yield changes in response to droughts. During Australia's Millennium Drought precipitation and soil moisture deficit reduced the average annual yield of the five largest crops.

    Many concepts regarding breeding ecology of waterfowl and the influences of environmental factors on annual production have changed in the past 20 years. These influences are especially pronounced in the prairie region of central North America where agriculture becomes more intensive each year. The principal task assigned to this Research Center when established in 1965 was to determine the relative impact of these influences on production and to identify those facets of breeding biology, nesting habitat requirements and other factors that may be altered to increase production on lands dedicated for this purpose. A corollary objective was to develop methods for enhancing production of waterfowl and other ground-nesting birds on private lands in agricultural areas. Some of the highlights of our findings to date, together with the results from current work of others, provide new information on waterfowl that indicates: (1) homing instincts are not as specific as indicated by earlier workers, (2) there are differences in pioneering between species, sexes and age classes, (3) strength and duration of pair bonds vary by species and age classes, (4) territorial tolerances for most species are greater than previously indicated, (5) there is differential productivity by age classes in some species, (6) there has been a gradual decline in nesting success in the prairie region the past 30 years, (7) adverse influences of intensive agriculture are increasing, (8) mammalian predation is an important factor, (9) high quality, secure nesting habitat and a complex of wetland types are the essential components of an optimum production unit, (10) the size and shape of blocks of nesting cover are important management considerations, (11) overharvest of local breeding populations is becoming a serious problem in some areas. Each of these subjects is discussed as related to research objectives and current management problems. Recommendations are presented for obtaining maximum

    Executive SummaryThe use of Landsat satellite imagery for global agricultural monitoring began almost immediately after the launch of Landsat 1 in 1972, making agricultural monitoring one of the longest-standing operational applications for the Landsat program. More recently, Landsat imagery has been used in domestic agricultural applications as an input for field-level production management. The enactment of the U.S. Geological Survey’s free and open data policy in 2008 and the launch of Landsat 8 in 2013 have both influenced agricultural applications. This report presents two primary sets of case studies on the applications and benefits of Landsat imagery use in agriculture. The first set examines several operational applications within the U.S. Department of Agriculture (USDA) and the second focuses on private sector applications for agronomic management.  Information on the USDA applications is provided in the U.S. Department of Agriculture Uses of Landsat Imagery for Global and Domestic Agricultural Monitoring section of the report in the following subsections:Estimating Crop Production.—Provides an overview of how Landsat satellite imagery is used to estimate crop production, including the spectral bands most frequently utilized in this application.Monitoring Consumptive Water Use.—Highlights the role of Landsat imagery in monitoring consumptive water use for agricultural production. Globally, a significant amount of agricultural production relies on irrigation, so monitoring water resources is a critical component of agricultural monitoring.

    Greenhouse gas (GHG) emissions from agriculture could be mitigated from both supple side and demand side. Assessing carbon footprint (CF) of agricultural production and food consumption could provide insights into the contribution of agriculture to climate change and help to identify possible GHG mitigation options. In the present study, CF of China's agricultural production was firstly assessed from site scale to national scale, and from crop production to livestock production. Data for the crop and livestock production were collected from field survey and national statistical archive, and both life cycle assessment and input-output method were employed in the estimations. In general, CF of crop production was lower than that of livestock production on average. Rice production ranked the highest CF in crop production, and the highest CFs of livestock production were observed in mutton and beef production. Methane emissions from rice paddy, emissions from fertilizer application and water irrigation exerted the largest contribution of more than 50% for CF of crop production; however, emissions from forage feeding, enteric fermentation and manure treatment made the most proportion of more than 90 % for CF of livestock production. In China, carbon efficiency was shown in a decreasing trend in recent years. According to the present study, overuse of nitrogen fertilizer caused no yield effect but significant emissions in some sites and regions of China, and aggregated farms lowered the CFs of crop production and livestock production by 3% to 25% and 6% to 60% respectively compared to household farms. Given these, improving farming management efficiency and farm intensive development is the key strategy to mitigate climate change from supply side. However, changes in food consumption may reduce GHG emissions in the production chain through a switch to the consumption of food with higher GHG emissions in the production process to food with lower GHG emissions. Thus, CFs

    Full Text Available Introduction: Risk is an essential component in the production and sale of agricultural products. Due to the nature of agricultural products, the people who act in this area including farmers and businesspersons encounter unpredictable fluctuations of prices. On the other hand, the firms that process agricultural products also face fluctuation of price of agricultural inputs. Given that the Canola is considered as one of the inputs of product processing factories, control of unpredictable fluctuations of the price of this product would increase the possibility of correct decision making for farmers and managers of food processing industries. The best available tool for control and management of the price risk is the use of future markets and options. It is evident that the pricing is the main pillar in every trade. Therefore, offering a fair price for the options will be very important. In fact, options trading in the options market create cost insurance stopped. In this way, which can reduce the risks of deflation created in the future, if the person entitled to the benefits of the price increase occurs in the future. Unlike the futures, market where the seller had to deliver the product on time, in the options market, there is no such compulsion. In addition, this is one of the strengths of this option contract, because if there is not enough product for delivery to the futures market as result of chilling, in due course, the farmers suffer, but in the options market there will be a loss. In this study, the setup options of rape, as a product, as well as inputs has been paid for industry. Materials and Methods: In this section. The selection criteria of the disposal of asset base for valuation of European put options and call option is been introduced.

    Drought is an extreme climatic situation where there is a water shortage arising due to sub-normal rainfall, erratic distribution of precipitation, increased water supply demand, etc. India faced several years of drought in last six decades. As Indian agriculture is largely dependent on the monsoon, a slight change affects production as well as crop yield drastically. Statistical analysis is important for mapping the drought prone areas. Raichur district of the northern interior state of Karnataka is a drought-prone region where the economy is mainly based on agriculture. So, the uneven distribution of rainfall as well as the delay in the arrival of the southwest monsoon adversely affects the growth stage of crops which result in a decline in crop production. The effect of drought on the agriculture for the past decade has been analyzed using crop productivity data. When the production rate of Raichur district was studied for the years 1998 to 2009, it was seen that major crops like rice and jowar faced a decline in its production during the years 2002 and 2003, whereas bajra, maize, etc. mostly decreased in the year 2004.

    The organization of agricultural production on the territory contaminated as a result of the Chernobyl reactor disaster involves prediction of the content of radionuclides in agro-industrial products. Traditional methods of prediting the contamination in the products does not give sufficient agreement with actual data and as a result it is difficult to make the necessary decisions about eliminating the consequences of the disaster in the agro-industrial complex. In many ways this is because the available methods are based on data on the radionuclide content in soils, plants, and plant and animal products. The parameters of the models used in the prediction are also evaluated on the basis of these results. Even if obtained from a single field or herd of livestock, however, such indicators have substantial variation coefficients due to various factors such as the spatial structure of the fallouts, the variability of the soil properties, the sampling error, the errors of processing and measuring the samples, and well as the data-averaging error. Consequently the parameters of the radionuclide transfer along the agricultural chains are very variable, thus considerably reducing the reliability of predicted values. The reliability of the prediction of radioactive contamination of agricultural products can be increased substantially by taking a probabilistic approach involving information about the random laws of contamination of farming land and the statistical features of the parameters of radionuclie migration along food chains. Considering the above, comparative analysis is made of the results obtained on the basis of the traditional treatment (deterministic in the simplest form) and its probabilistic analog

    Full Text Available The use of lignocellulosic biomass as a substrate in agricultural biogas plants is very popular and yields good results. However, the efficiency of anaerobic digestion, and thus biogas production, is not always satisfactory due to the slow or incomplete degradation (hydrolysis of plant matter. To enhance the solubilization of the lignocellulosic biomass various physical, chemical and biological pretreatment methods are used.The aim of this study was to select and characterize cellulose-degrading bacteria, and to construct a microbial consortium, dedicated for degradation of maize silage and enhancing biogas production from this substrate.Over one hundred strains of cellulose-degrading bacteria were isolated from: sewage sludge, hydrolyzer from an agricultural biogas plant, cattle slurry and manure. After physiological characterization of the isolates, sixteen strains (representatives of Bacillus, Providencia and Ochrobactrum genera were chosen for the construction of a Microbial Consortium with High Cellulolytic Activity, called MCHCA. The selected strains had a high endoglucanase activity (exceeding 0.21 IU/mL CMCase activity and a wide range of tolerance to various physical and chemical conditions. Lab-scale simulation of biogas production using the selected strains for degradation of maize silage was carried out in a two-bioreactor system, similar to those used in agricultural biogas plants.The obtained results showed that the constructed MCHCA consortium is capable of efficient hydrolysis of maize silage, and increases biogas production by even 38%, depending on the inoculum used for methane fermentation. The results in this work indicate that the mesophilic Microbial Consortium with High Cellulolytic Activity has a great potential for application on industrial scale in agricultural biogas plants.

    Full Text Available As in many transition countries, also in Georgia rural urban migration as well as migration from the agricultural sector takes place. This also applies to the Kazbegi district, a mountainous region in the Greater Caucasus of Georgia. The main activity in the district is subsistence farming, while only a few agricultural producers are commercially active. As the region offers beautiful nature, during the last decade tourism has been on the rise, while a dwindling interest in the agricultural sector can be observed. However, the growth in tourism also provides opportunities for small-scale agricultural producers to increase their income by marketing their surplus production to the local tourism sector and thereby improving their livelihoods. In turn, an increase in local agri-food products offered might have a positive effect on the tourism sector. Thus, establishing linkages of agricultural food production and rural tourism might contribute to the economic development of the district and even counteract migration to the capital and from the agricultural sector. Through a qualitative study, we aim at identifying local agri-food products suitable for being marketed to the tourism sector and efficient marketing options. In order to do so, we analyze local agri-food chains. Exploratory interviews, focus group discussions and expert interviews provide data for a qualitative content analysis. First results show that food products which require little technological equipment for processing and do not underlie strict food safety standards, like for example honey, seem to be adequate to tap marketing potentials with regard to rural tourism.

    Due to contaminating effects from nuclear explosions and nuclear power plants, the systematic investigation of environmental radioactive contamination is absolutely necessary. In order to reduce the artificial radiation dose to which the human body is exposed, isotope content of foods and agricultural products should be known. The authors evaluate the decontamination possibilities of food produced from vegetable and animal products, starting from the contamination of some products. For vegetable product decontamination the use of suitable fertilizers, thorough scrubbing in excess water and, for cereals, milling is proposed. As the most effective preventive measure of radiation contamination of food products of animal origin, appropriate packing is proposed. The storage and preservation problems are emphasized for short half-life radiation contamination. (P.J.)

    Full Text Available In the most developed countries of Western Europe and North America, the share of organic farming in the food market is between 2% and 6%. The share of organic products on the Polish food market is only 0.33% (Dryjańska E. 2017. The aim of this article is to compare organic agricultural products in the US and EU. The scope of the comparison was covered by the legal regulations for organic production in the mentioned regions and the availability of organic products for customers. In order to highlight differences between the organic product and their traditional counterpart, selected meta-analyzes were conducted by authors in the field of medical and natural sciences. The possibilities of buying organic products are described on the basis of personal experiences of the author as a consumer. The offer of organic products was analyzed on the example of one European country (Poland and the example of several states of America (Colorado, Virginia, New York. The rules for producing organic food in the US are more rigorous than in the EU. The offer of organic and conventional food targeted to the American consumer is comparable. Although Polish consumers have a positive perception of organic food, its supply is significantly different from the US market. The main differences are in distribution channels, product range, price and visual design of organic products.

    The U.S. Departments of Agriculture and Energy jointly analyzed the economic potential for, and impacts of, large-scale bioenergy crop production in the United States. An agricultural sector model (POLYSYS) was modified to include three potential bioenergy crops (switchgrass, hybrid poplar, and willow). At farmgate prices of US $2.44/GJ, an estimated 17 million hectares of bioenergy crops, annually yielding 171 million dry Mg of biomass, could potentially be produced at a profit greater than existing agricultural uses for the land. The estimate assumes high productivity management practices are permitted on Conservation Reserve Program lands. Traditional crops prices are estimated to increase 9 to 14 percent above baseline prices and farm income increases annually by US $6.0 billion above baseline. At farmgate prices of US $1.83/GJ, an estimated 7.9 million hectares of bioenergy crops, annually yielding 55 million dry Mg of biomass, could potentially be produced at a profit greater than existing agricultural uses for the land. The estimate assumes management practices intended to achieve high environmental benefits on Conservation Reserve Program lands. Traditional crops prices are estimated to increase 4 to 9 percent above baseline prices and farm income increases annually by US $2.8 billion above baseline

    Nuclear techniques are appropriate tools to settle problems for agriculture or natural resources which cannot be solved using conventional agricultural techniques. In this paper, the research activities carried out and the achievements so far obtained in the agricultural specialties -all by using nuclear techniques- with particular reference to pasture management are discussed. Insect pest control by Sterile Insect Techniques (SIT); soil and water management using neutron moisture probes; determining N-fixation capacity of legumes using N-15 isotope and nuclear methods; soil erosion measurement using of fallout radionuclide such as Cs-137; monitoring the movement of saline water in salt-affected land using isotopes of chlorine; livestock production and health by RIA and ELISA are some of achievements so far obtained in improving agricultural productivity. The ultimate goal of the nuclear technique investigation in agriculture is to use the resources efficiently in obtaining higher plant and livestock yields while increasing the quality and protecting them against insects, diseases and weeds.

    Countries in the Middle East use a large fraction of their scarce water resources to produce cash crops, such as fruit and vegetables, for international markets. At the same time, these countries import large amounts of staple crops, such as cereals, required to meet the nutritional demand of their populations. This makes food security in the Middle East heavily dependent on world market prices for staple crops. Under these preconditions, increasing food demand due to population growth, urban expansion on fertile farmlands, and detrimental effects of a changing climate on the production of agricultural commodities present major challenges to countries in the Middle East that try to improve food security by increasing their self-sufficiency rate of staple crops.We applied the spatio-temporal land-use change model LandSHIFT.JR to simulate how an expansion of urban areas may affect the production of agricultural commodities in Jordan. We furthermore evaluated how climate change and changes in socio-economic conditions may influence crop production. The focus of our analysis was on potential future irrigated and rainfed production (crop yield and area demand) of fruit, vegetables, and cereals. Our simulation results show that the expansion of urban areas and the resulting displacement of agricultural areas does result in a slight decrease in crop yields. This leads to almost no additional irrigation water requirements due to the relocation of agricultural areas, i.e. there is the same amount of "crop per drop". However, taking into account projected changes in socio-economic conditions and climate conditions, a large volume of water would be required for cereal production in order to safeguard current self-sufficiency rates for staple crops. Irrigation water requirements are expected to double until 2025 and to triple until 2050. Irrigated crop yields are projected to decrease by about 25%, whereas there is no decrease in rainfed crop yields to be expected.

    2015-05-01

    Important antibiotics in human medicine have been used for many decades in animal agriculture for growth promotion and disease treatment. Several publications have linked antibiotic resistance development and spread with animal production. Aquaculture, the newest and fastest growing food production sector, may promote similar or new resistance mechanisms. This review of 650+ papers from diverse sources examines parallels and differences between land-based agriculture of swine, beef, and poultry and aquaculture. Among three key findings was, first, that of 51 antibiotics commonly used in aquaculture and agriculture, 39 (or 76%) are also of importance in human medicine; furthermore, six classes of antibiotics commonly used in both agriculture and aquaculture are also included on the World Health Organization's (WHO) list of critically important/highly important/important antimicrobials. Second, various zoonotic pathogens isolated from meat and seafood were observed to feature resistance to multiple antibiotics on the WHO list, irrespective of their origin in either agriculture or aquaculture. Third, the data show that resistant bacteria isolated from both aquaculture and agriculture share the same resistance mechanisms, indicating that aquaculture is contributing to the same resistance issues established by terrestrial agriculture. More transparency in data collection and reporting is needed so the risks and benefits of antibiotic usage can be adequately assessed.

    2013-12-01

    As global and regional populations continue to rise for the next several decades, the need to grow more food will worsen old -- and produce new -- challenges for water resources. Expansion of irrigated agriculture is slowing due to constraints on land and water, and as a result, some have argued that future new food demands will only be met through improvements in agricultural productivity on existing irrigated and rainfed cropland, reductions in field losses and food waste, and social changes such as dietary preferences. This talk will address the central role that improvements in water-use productivity can play in the food/water/population nexus. In particular, the ability to grow more food with less water will have a great influence on whether future food demands will be met successfully. Such improvements can come about through changes in technology, regulatory systems, economic incentives and disincentives, and education of water users. Example of potential savings from three different strategies to improve agricultural water productivity in California. (From Pacific Institute).

    Agriculture is a major source of greenhouse gas (GHG) emissions globally. The growing global population is putting pressure on agricultural production systems that aim to secure food production while minimising GHG emissions. In this study, the GHG emissions associated with the production of major food commodities in India are calculated using the Cool Farm Tool. GHG emissions, based on farm management for major crops (including cereals like wheat and rice, pulses, potatoes, fruits and vegetables) and livestock-based products (milk, eggs, chicken and mutton meat), are quantified and compared. Livestock and rice production were found to be the main sources of GHG emissions in Indian agriculture with a country average of 5.65 kg CO 2 eq kg -1 rice, 45.54 kg CO 2 eq kg -1 mutton meat and 2.4 kg CO 2 eq kg -1 milk. Production of cereals (except rice), fruits and vegetables in India emits comparatively less GHGs with foods could greatly increase GHG emissions from Indian agriculture. A range of mitigation options are available that could reduce emissions from current levels and may be compatible with increased future food production and consumption demands in India.

    Antimicrobial peptides (AMPs) are vital components of the innate immune system of nearly all living organisms. They generally act in the first line of defense against various pathogenic bacteria, parasites, enveloped viruses and fungi. These low molecular mass peptides are considered prospective therapeutic agents due to their broad-spectrum rapid activity, low cytotoxicity to mammalian cells and unique mode of action which hinders emergence of pathogen resistance. In addition to medical use, AMPs can also be employed for development of innovative approaches for plant protection in agriculture. Conferred disease resistance by AMPs might help us surmount losses in yield, quality and safety of agricultural products due to plant pathogens. Heterologous expression in plant-based systems, also called plant molecular farming, offers cost-effective large-scale production which is regarded as one of the most important factors for clinical or agricultural use of AMPs. This review presents various types of AMPs as well as plant-based platforms ranging from cell suspensions to whole plants employed for peptide production. Although AMP production in plants holds great promises for medicine and agriculture, specific technical limitations regarding product yield, function and stability still remain. Additionally, establishment of particular stable expression systems employing plants or plant tissues generally requires extended time scale for platform development compared to certain other heterologous systems. Therefore, fast and promising tools for evaluation of plant-based expression strategies and assessment of function and stability of the heterologously produced AMPs are critical for molecular farming and plant protection.

    From the background of small peasant management and information asymmetry,this paper introduced the middle profit sharing model and discussed influence factors and ownership of pricing power of agricultural products. It obtained following results:( i) the transaction scale has positive effect on farmer’s pricing power of agricultural products,while the competitor’s transaction scale has negative effect on it,so does the cost for information search;( ii) under the condition of small peasant management system,farmer is in a relatively weak position in the distribution of pricing power of agricultural products,due to factors such as small transaction scale,information asymmetry and farmer’s weak negotiation ability;( iii) through cooperative game,farmer and buyers can share cooperative surplus at the agreed ratio;( iv) the introduction of self-organizing specialized farmers cooperatives is favorable for solving the problem of pricing power of agricultural products,and possible problems,such as " collective action dilemma" and " fake cooperatives" in the cooperative development process can be solved by internal and external division of labor and specialization of cooperatives.

  4. Regional identity can add value to agricultural products

    Full Text Available Regional identity creation is being recognized for its economic benefits and as a strategic resource for producer communities. A regional identity is not a brand; it is built through a complicated process of developing cohesion and sharing in the industry community and communicating outside the industry community to opinion-makers and consumers. The California fine wine industry has built successful regional identities and leveraged them to add value to their wines. As regional identities in the wine industry have strengthened, so has the industry, and a symbiotic relationship with other local value-added industries, such as tourism and hospitality, has emerged. Other agricultural producers can learn from the identity creation experiences in the wine industry. With the many challenges faced by California agriculture, identity formation may offer producers new ideas for adding value to their products and finding larger markets.

  5. The Growth Path of Agricultural Labor Productivity in China: A Latent Growth Curve Model at the Prefectural Level

    Full Text Available Given the shrinking proportion of agriculture output and the growing mobility of the labor force in China, how agricultural labor productivity develops has become an increasingly attractive topic for researchers and policy makers. This study aims to depict the development trajectory of agricultural labor productivity in China after its WTO entry. Based on a balanced panel data containing 287 Chinese prefectures from 2000 to 2013, this study applies the Latent Growth Curve Model (LGCM and finds that the agricultural labor productivity follows a piecewise growth path with two breaking points in the years of 2004 and 2009. This may stem from some exogenous stimulus, such as supporting policies launched in the breaking years. Further statistical analysis shows an expanding gap of agricultural labor productivity among different Chinese prefectures.

    The concept of sustainable agriculture encompasses ecological, economic and social problems in which weather and climate can be of great importance. Despite considerable technological advancement and improved irrigation facilities, Indian farmers are still dependent on seasonal rains, which are highly variable both in time and space. Inclement weather events like droughts, floods, cold and heat waves, hails, squalls, tropical storms severely affect the agricultural production. Their harmful effects may be partially reduced if the occurrence of these events is predicted in advance and farmers are suitably advised to take preventive/corrective measures. With the objective to help the farmers maximize profits by decreasing weather related losses, increasing the timeliness of farm operations and to reduce environmental pollution through the optimal use of agricultural chemicals, the location specific/regional Agrometeorological Advisory Service was initiated in the year 1991. The forecasting skills of most of the weather parameters at Hisar have improved considerably over the years. Now, it is time to integrate and make use of vast agrometeorological information available online in preparing weather based advisories for in-season agricultural operations both for single locations and on a meso or regional scale as desired. This can be further strengthened through input from new technologies such as neural network, remote sensing, GIS, ground measurements and modeling applications along with traditional wisdom available with the farming communities should be integrated to further strengthen the location specific weather forecasting system for the development of sustainable and more efficient crop production systems.

    Nutrition science-based dietary advice urges changes that may have a great impact on agricultural systems. For example, the 2016 Dietary Guidelines for Americans (DGA) recommends greatly increased fruit and vegetable consumption, but the present domestic production is insufficient to accommodate large-scale adoption of these guidelines. Increasing production to the extent needed to meet the DGA will necessitate changes in an already stressed agriculture and food system and will require nutrition and agriculture professionals to come together in open and collegial discourse. All involved need to understand the stress placed on the food system by increasing populations, changing diets, and changing environments, and recognize the major diet-based public health challenges. Furthermore, there is a need to understand the intricate interplay of the myriad parts of the food system and the vast amount of work necessary to make even small changes. New systems approaches are needed, especially at the research level, where nutrition, public health, agriculture, and the food industry work together to solve interconnected problems. Future well-being depends on a sustainable food system that continues to deliver optimal health with minimal impact on the environment. © 2017 American Society for Nutrition.

    The Fifth Assessment Report of the Intergovernmental Panel on Climate Change identifies drought as one of the major climate risks in South Asia. During past two decades, a large amount of climate data have been made available by the scientific community, but the deployment of climate information for local level and agricultural decision making remains less than optimal. The provisioning of locally calibrated, easily accessible, decision-relevant and user-oriented information, in the form of drought advisory service could help to prepare communities to reduce climate vulnerability and increase resilience. A collaborative effort is now underway to strengthen existing and/or establish new drought monitoring and early warning systems in Afghanistan, Bangladesh, Nepal and Pakistan by incorporating standard ground-based observations, earth observation datasets, and numerical forecast models. ICT-based agriculture drought monitoring platforms, hosted at national agricultural and meteorological institutions, are being developed and coupled with communications and information deployment strategies to enable the rapid and efficient deployment of information that farmers can understand, interpret, and act on to adapt to anticipated droughts. Particular emphasis is being placed on the calibration and validation of data products through retrospective analysis of time series data, in addition to the installation of automatic weather station networks. In order to contextualize monitoring products to that they may be relevant for farmers' primary cropping systems, district level farming practices calendars are being compiled and validated through focus groups and surveys to identify the most important times and situations during which farmers can adapt to drought. High-resolution satellite crop distribution maps are under development and validation to add value to these efforts. This programme also aims to enhance capacity of agricultural extension staff to better understand

    Sub-Saharan Africa is one of the regions with the largest scope for improved agricultural development that would contribute to global food security while respecting environmental boundaries. More importantly, undernourishment is a challenge for many African countries and needs to be addressed to achieve the 2030 Agenda for Sustainable Development. This study was conducted to support the Netherlands Ministry of Foreign Affair's Inclusive Green Growth aim of increasing water use efficiency by 25% in Dutch financed projects. A water footprint profile was developed for 7 Sub-Saharan countries; Benin, Ethiopia, Ghana, Kenya, Mali, Mozambique and Rwanda. The profiles provide an overview of water use from the perspective of the goods produced within the country, the consumption of goods, in particular agricultural crops, whether these goods are produced domestically or imported from other countries and the level of blue water scarcity experienced in the country. Across all countries, key food crops such as maize, and sorghum have low water productivity relative to the global water footprint benchmark. Export crops such as tea in Kenya or cocoa in Ghana show a good performance over global production. Furthermore, the water footprint of crops over the period 2006-2013 was compared to data from the period 1996-2005. Changes in yield and the resulting changes in the water footprint were assessed for both food and export crops. Yields in food crops improved in some countries, and in some years, but not consistently across all countries and years. The greatest gains in water productivity were in key export crops. The results provide insights into whether improvements have been made in water productivity in recent years and through comparison with the global water footprint benchmark, remaining opportunities for further gains in water productivity were identified. Going forward, policies that will enhance further improvement in water productivity and support greater food and

    Full Text Available In recent years, there has been an increasing interest in Life Cycle Assessment (LCA applied to estimate the cradle-to-grave environmental impact of agricultural products or processes. Furthermore, including in the analysis an economic evaluation, from the perspective of an integrated life cycle approach, appears nowadays as a fundamental improvement. In particular, Life Cycle Costing (LCC, is a method that could integrate financial data and cost information with metrics of life cycle approaches. In this study, LCA in conjunction with LCC methods were used, with the aim to evaluate the main cost drivers—environmental and economic—of five widely diffused and market-valued agricultural productions (organic tomato and pear, integrated wheat, apple and chicory and to combine the results in order to understand the long-term externalities impacts of agricultural productions. Data obtained in local assessment show a wide margin of improvement of resources management at farms level in the short-term, but also allow for the investigation of future effects of environmental impacts not expressed in product price on the market. Reaching a real sustainable model for agriculture could be a value added approach firstly for farmers, but also for all the people who live in rural areas or use agricultural products.

    Full Text Available In this paper, the analysis of the price elasticity of demand of four different categories of agricultural products in the Republic of Serbia was described. Differentiating the price and demand of these products by sales points, and using the least squares approximation method, the elasticity for all different agricultural categories was expressed in the functional form. According to this, the coefficients of elasticity of the price and demand were computed and between different agricultural categories were analyzed. The results we obtained show that the market of agricultural products in Serbia is mostly inelastic because the coefficients of inelasticity and indifference of demand to change of prices, are dominant. The influence of factors on the elasticity of demand that are not of price character, proved to be very pronounced. The relationship of the two segments of agricultural market (markets and shops was also analysed and it was demonstrated that these two segments have a slight correlation.

    Full Text Available Introduction: The relationship between openness, trade and environmental damaging are the most important problems in the early 1990s. Some scientists assume the environmental quality is a normal good and increasing income increases demand for environmentally safe products. Therefore, Firms will be encouraging the using of safer and less polluting procedure. On the other hand other scientists assume international trade grows the environmental degradation through environmentally polluting industries and expand economics scales in developing countries. While environmental standards are low in these countries, the expansion of trade will lead to more pollution. Some experimental studies have confirmed a negative relationship between trade and environment. The effect of import and export of trade is not considered as important components of trade, despite very consideration of the relationship between openness, trade and environmental by researchers while in general part trade may have different effect on environmental. Materials and Methods: The base model is used to study the relationship between economic growth and environmental indexes and trade. Grossman and Krueger (1991 and Shafik and Bandvpady (1992 used the trade intensity variable, obtained from the ratio of exports plus imports divided by GDP as the World Trade openness of an economy measure. Grossman and Krueger (1991, the first person who developed environmental Kuznets curve (EKC used multiple versions of the model. Instrumental variable regression model has been estimated using panel data of period 1998 and 2009 for 73 countries, including 27 development countries and 46 developing countries.

    Future land use and the consequent land cover change will have a significant impact on future climate through biogeophysical (albedo, surface roughness and latent heat transfer, etc.) as well as biogeochemical (greenhouse gas emissions etc.) mechanisms. One of the major determinants of the extent of land use induced land cover change is the agricultural productivity growth within the socio-economic models used for developing the RCP scenarios. There are considerable uncertainties in the size of agricultural productivity under climate change, as yields are projected to vary spatially in signal and strength. Previous climate modeling work has considered the impacts to the carbon cycle of different levels of agricultural productivity growth, but has failed to consider the biogeophysical effects of the land use induced land cover change on climate. Here we examine the climate impacts of the assumption of agricultural productivity growth and business as usual land use. The effects are considered through the biogeophysical land use induced land cover change, using the Hadley Centre climate model HadGEM2. The model simulations use the set biogeochemical climate forcing of the RCP 4.5 scenario, but the biogeophysical land use change specification is altered over a 100 year simulation. Simulations are run with combinations of no land use change; standard RCP 4.5 land use change; business as usual land use change; and zero agricultural productivity growth. The key effect of no agricultural productivity growth is that more cropland is required to feed the same population, necessitating cropland expansion. The expansion of cropland and consequent deforestation increases the albedo and gives an extensive cooling effect in the northern hemisphere (up to 2°C). Differences in global mean temperature between the zero agricultural productivity growth with business as usual land use change specified run and the standard RCP 4.5 run are -0.2°C by 2040 and -0.7°C by 2100. There is

    Debats, Stephanie Renee

    Smallholder farms dominate in many parts of the world, including Sub-Saharan Africa. These systems are characterized by small, heterogeneous, and often indistinct field patterns, requiring a specialized methodology to map agricultural landcover. In this thesis, we developed a benchmark labeled data set of high-resolution satellite imagery of agricultural fields in South Africa. We presented a new approach to mapping agricultural fields, based on efficient extraction of a vast set of simple, highly correlated, and interdependent features, followed by a random forest classifier. The algorithm achieved similar high performance across agricultural types, including spectrally indistinct smallholder fields, and demonstrated the ability to generalize across large geographic areas. In sensitivity analyses, we determined multi-temporal images provided greater performance gains than the addition of multi-spectral bands. We also demonstrated how active learning can be incorporated in the algorithm to create smaller, more efficient training data sets, which reduced computational resources, minimized the need for humans to hand-label data, and boosted performance. We designed a patch-based uncertainty metric to drive the active learning framework, based on the regular grid of a crowdsourcing platform, and demonstrated how subject matter experts can be replaced with fleets of crowdsourcing workers. Our active learning algorithm achieved similar performance as an algorithm trained with randomly selected data, but with 62% less data samples. This thesis furthers the goal of providing accurate agricultural landcover maps, at a scale that is relevant for the dominant smallholder class. Accurate maps are crucial for monitoring and promoting agricultural production. Furthermore, improved agricultural landcover maps will aid a host of other applications, including landcover change assessments, cadastral surveys to strengthen smallholder land rights, and constraints for crop modeling

    coefficients. Results and Discussion: Main results showed that real exchange rate volatility and export value of selected commodities are Co-integrated. The coefficient estimation of FMOLS and DOLS methods are equal and statically significant; so, these methods aren’t statically different and they showed that real exchange rate volatility has a negative impact on exported value for whole panel. However, the specific coefficient for each commodity showed contradictory behavior in short run and long run; for example real exchange rate fluctuation has a negative and significant impact on all the commodities; but, in short run this variable has a positive and significant impact on exported value. Moreover, based on estimated results it seems that fluctuation in exchange market has a greater impact on more valuable commodities like date. Conclusion: Considering the importance of agricultural product trade and in order to overcome mono-product economy, this study investigated long term and short term relation between export of grape, orange, date and exchange rate volatilities. To this aim, first the index of exchange volatility using generated autoregressive conditional heteroscedasticity (GARCH was calculated. In order to investigate the relation between exchange rate volatilities and export value of agricultural product, unit root test and cointegration test related to panel data were used during years 1971-2013. The results of model estimation showed that exchange rate volatilities in short term and long term have respectively positive and negative effects on the export value of orange, grape and date. In long term, the negative effects of Exchange rate volatilities on high-export-value products are more than its effects on low-export-value products. Based on the estimation results we can conclude that, in short run, exporters are willing to increase their interchange and gain profits of the volatility in exchange market; however, in long run exchange rate fluctuation has

    Frequent natural calamities, extreme climatic events and unexpected seasonal changes are the obvious examples of global warming. Carbon emissions by industrial units all over the world are believed to be the major contributor of the global warming that can lead to reduced agricultural productivity. This paper examines the impact of CO emission on agricultural productivity in Southeast Asian countries. It investigates the dynamic relationship between CO emission (along with other control-variables) and agricultural output using panel data set comprising data from Southeast Asian countries. Following the dynamic heterogeneous panel techniques developed by Pesaran and Shin (1999) for estimating the short- run and long-run effects using autoregressive distributed lag (ARDL) model in the error correction form, the study then estimated the empirical model based on pooled mean group (PMG) estimator. The study found that increased CO emission resulted in higher agricultural productivity because of the fact that farmers around the globe quickly adapt to climate change. In addition, use of submersible pump and other capital machineries significantly increased agricultural yield and led to reduced dependency on human capital, while use of chemical fertilizers increased productivity in short-run but had a harmful impact in the long-run.

    As part of its climate policy, Germany promotes the production of biogas via its so-called Renewable-Energy-Act (EEG). The resulting boost in biogas output went along with a significant increase in production of green maize, the dominant feedstock. Existing studies of the EEG have analysed its impacts on German agriculture without considering market feedback. We thus expand existing quantitative analysis by also considering impacts on European and global agricultural markets, land use and the environment by combining a detailed location model for biogas plants, the Regionalised Location Information System-Maize (ReSi-M2012), with a global Partial Equilibrium model for agriculture, the Common Agricultural Policy Regional Impact (CAPRI) model. Our results indicate that the German biogas production is large enough to have sizeable impacts on global agricultural markets in prices and quantities, causing significant land use change outside of Germany. While profits in the agricultural sector increase, food consumer face higher prices, and subsidies for biogas production are passed on to electricity consumers. The German biogas program, as long as it is almost entirely based on non-waste feedstocks, is probably not a promising avenue towards a GHG-saving renewable energy production, but a rather expensive one. - Highlights: • Recent changes to that program decrease green maize use but increase land demands. • The program could raise EU prices for cereals by 3%. • Agricultural land use expansion outside of the EU estimated at 1 Mio ha

    Full Text Available Agricultural business is a very high-risk job and an increase demand for agricultural products from one side and steady increase in production cost and weather changes, on the other side, have motivated many to use insurance for agricultural products. Insurance plays an important role in influencing crop production and insured satisfaction or farmers. The purpose of this research is to find critical components in agricultural insurance. Based on an exploration of the literature review and interviews, the proposed study of this paper extracts 24 variables and using factor analysis, we select the most important factors, which are grouped in seven categories. The implementation of our factor analysis has revealed uncertainty, moderator, market equilibrium, risky environment, empowering factor, education, training, structural hazards and natural ecosystems as the most important factors influencing agricultural industry.

    The influence of predictive contamination to agricultural products due to the wet processes as well as dry processes from radioactive air concentration during a nuclear emergency is comprehensively analyzed. The previous dynamic food chain model DYNACON considering Korean agricultural and environmental conditions, in which the initial input parameter was radionuclide concentrations on the ground, is improved so as to evaluate radioactive contamination to agricultural products from either radioactive air concentrations or radionuclide concentrations on the ground. As for the results, wet deposition is a more dominant mechanism than dry deposition in contamination on the ground. While, the contamination levels of agricultural products are strongly dependent on radionuclide and precipitation when the deposition of radionuclides occurs. It means that the contamination levels of agricultural products are determined from which is the more dominant process between deposition on the ground and interception to agricultural plants

    While food security is a main challenge faced by human kind, intensive agriculture often leads to soil degradation which then can threaten productivity. Maize is one of the most important crops across the world, with 869 million tons produced worldwide in 2012/2013 (IGC 2015), of which 929.5 thousand tons in Portugal (INE 2014). In Portugal, maize is sown in April/May and harvest occurs generally in October. Conventional maize production requires high inputs of water and fertilizers to achieve higher yields. As Portuguese farmers are typically rather old (on average, 63 years) and typically have a low education level (INE 2014), sustainability of their land management practises is often not a principal concern. This could explain why, in 2009, only 4% of the Portuguese temporary crops were under no-tillage, why only 8% of the farmers performed soil analyses in the previous three years, and why many soils have a low organic matter content (INE 2014). Nonetheless, sustainable land management practices are generally accepted to be the key to reducing agricultural soil degradation, preventing water pollution, and assuring long-term crop production objectives and food security. Sustainable land management should therefore not only be a concern for policy makers but also for farmers, since land degradation will have negative repercussions on the productivity, thus, on their economical income. This paper aims to assess the impact of maize production on soil properties. The study focusses on an 8 ha maize field located in central Portugal, with a Mediterranean climate on a gently sloping terrain (<3%) and with a soil classified as Eutric Fluvisol. On the field, several experiments were carried out with different maize varieties as well as with different fertilizers (solid, liquid and both). Centre pivot irrigation was largely used. Data is available from 2003, and concerns crop yield, fertilization and irrigation practices, as well as soil properties assessed through

    To measure the association between different chronic conditions and non-agricultural work productivity loss among the middle-aged Chinese population. We used 2011, 2013 and 2015 data from the China Health and Retirement Longitudinal Study. The study focused on middle-aged respondents who had the potential to work in the non-agricultural sector. Work productivity loss was measured by non-agricultural work participation and number of absent workdays among those conducting non-agricultural work. Seven different chronic conditions were considered. Heart diseases had the strongest association with lower work participation for men and women. Stomach/digestive disease and arthritis/rheumatism were conditions with the largest incremental absent workdays for men and women, respectively. The associations with non-agricultural work productivity loss varied by chronic conditions, outcomes, and sex. The findings will help motivate chronic condition prevention/management programs and set priorities.

    Weather related crop losses have always been a concern for farmers On a wider scale it has always influenced decision of Governments traders and other policy makers for the purpose of balanced food supplies trade and distribution of aid to the nations in need Therefore national policy and decision makers are giving increasing importance to early assessment of crop losses in response to weather fluctuations This presentation emphasizes utility of AVHRR-based Vegetation health index VHI for early warning of drought-related losses of agricultural production in China The VHI is a three-channel index characterizing greenness vigor and temperature of land surface which can be used as proxy for estimation of how healthy and potentially productive could be vegetation China is the largest in the world producer of grain including wheat and rice and cotton In the major agricultural areas China s crop production is very dependent on weather The VHI being a proxy indicator of weather impact on vegetation showed some correlation with productivity of agricultural crops during the critical period of their development The periods of the strongest correlation were investigated and used to build regression models where crop yield deviation from technological trend was accepted as a dependent and VHI as independent variables The models were developed for several major crops including wheat corn and soybeans

  6. Adapting Agricultural Production Systems to Climate Change—What’s the Use of Models?

    Full Text Available Climate change poses a challenge to agricultural production and its impacts vary depending on regional focus and on the type of production system. To avoid production losses and make use of emerging potentials, adaptations in agricultural management will inevitably be required. Adaptation responses can broadly be distinguished into (1 short-term incremental responses that farmers often choose autonomously in response to observed changes and based on local knowledge and experiences, and (2 long-term transformative responses that require strategic planning, and which are usually implemented at a larger spatial scale. Models can be used to support decision making at both response levels; thereby, different features of models prove more or less valuable depending on the type of adaptation response. This paper presents a systematic literature review on the state-of-the-art in modelling for adaptation planning in agricultural production systems, investigating the question of which model types can be distinguished and how these types differ in the way they support decision making in agricultural adaptation planning. Five types of models are distinguished: (1 empirical crop models; (2 regional suitability models; (3 biophysical models; (4 meta-models; and (5 decision models. The potential and limitations of these model types for providing decision-support to short- and long-term adaptation planning are discussed. The risk of maladaptation—adaptation that implies negative consequences either in the long term or in a wider context—is identified as a key challenge of adaptation planning that needs more attention. Maladaptation is not only a risk of decision making in the face of incomplete knowledge of future climate impacts on the agricultural production system; but it can also be a threat if the connectedness of the agroecosystem is not sufficiently acknowledged when management adaptations are implemented.

    The demand for biofuel pellets has increased considerably in recent years, causing shortage of the traditional raw materials sawdust and wood shavings. In this study, the costs and energy requirements for the production of pellets from agricultural raw materials were analysed. The materials studied were Salix, reed canary grass, hemp, straw, screenings, rape-seed meal, rape cake and distiller's waste. Four production scales were analysed, having an annual output of 80,000, 8000, 800 and 80 tonnes of pellets per year. It was concluded that the raw materials of greatest interest were Salix and reed canary grass. They had competitive raw material costs and acceptable fuel properties and could be mixed with sawdust in existing large-scale pelleting factories. Straw had low production costs but can cause serious ash-related problems and should, as also is the case for screenings, be avoided in small-scale burners. Hemp had high raw material costs and is of less commercial interest, while distiller's waste, rape-seed meal and rape cake had higher alternative values when used as protein feed. The scale of production had a crucial influence on production costs. The machinery was used much more efficiently in large-scale plants, resulting in clear cost savings. Small-scale pelleting, both static and mobile, required cheap raw materials, low labour costs and long utilisation times to be profitable. In most cases, briquetting would be more commercially viable. The energy use in manufacturing pellets from air-dried crops was generally no higher than when moist sawdust was used as the raw material. (author)

    Full Text Available The deficiency of micronutrients (zinc, iron, iodine and vitamin A is persistently afflicting millions of people living across Africa, Southern Americas, Asia and Pakistan. Among these, the zinc deficiency syndrome is occurring by 47.6, 41.3, and 39.2% in pregnant, non-pregnant and children under 5 years, respectively in Pakistan. The reason being that majority of the people subsists on cereal-based diets, i.e., wheat. The commercially grown wheat varieties contain zinc about 25 mg/g, whereas about 40 mg/g zinc is required in daily diet.The potential risk of zinc deficiency could be mitigated through certain interventions i.e., mineral drugs, food supplements, diversity in diets, production of fortified foods, and genetic biofortification of staple food crops. Among these, quantum increase in zinc content in wheat grains through genetic manipulation would be basics to alleviate zinc deficiency in the malnourished communities. The objective of the programme is to enhance the concentration of zinc nutrient from 25 to 40 mg/g in wheat grains through conventional plant breeding techniques.Pakistan Agricultural Research Council, Islamabad in collaboration with Consultative Group on International Agricultural Research (CGIAR and International Maize & Wheat Improvement Center (CIMMYT and HarvestPlus, Pakistan started R&D works to develop biofortified high zinc wheat varieties containing around 40 mg/g in the year 2009. The biofortified wheat crop is developed through conventional plant breeding techniques. The germplasm inherited with high zinc nutrient are crossed with high yielding and adopted to ecological conditions. The varieties are high yielding, and inheriting zinc around 40 mg/g in the grains under both irrigated and rainfed production environments. The Government of Punjab has also given high priority to develop and consume biofortified high zinc wheat in its multi-sectoral Nutrition Strategy Plan 2015, as potential agricultural option to

    Transfer of radionuclides to agricultural products and their removal before ingestion are reviewed briefly. Ingestion of {sup 137}Cs through various food groups were intensively has been studied from 1960s. The results of these studies indicated that cereals were relatively important food groups in Japan, while dairy products were a critical food group in Western countries. However, Westernization of Japanese diet and other factors recently make dairy products more important. In the case of {sup 137}Cs ingestion from the Chernobyl accident, 43% of total {sup 137}Cs intake was ingested through dairy products. The removal of radionuclides from food by washing, preparing and cooking is also discussed. (author)

    Combined with deposition model onto the ground of radionuclides, the influence of radioactive contamination to agricultural products was analyzed due to wet deposition as well as dry deposition from radioactive air concentration during a nuclear emergency. The previous dynamic food chain model, in which initial input parameter is only radionuclide concentrations on the ground, was improved for the evaluating of radioactive contamination to agricultural products from either radionuclide concentrations in air or radionuclide concentrations on the ground. As the results, in case of deposition onto the ground, wet deposition was more dominant process than dry deposition. While the contamination levels of agricultural products were dependent on the a variety of factors such as radionuclides and rainfall rate. It means that the contamination levels of agricultural products are determined from which is more dominant process between deposition on the ground and interception onto agricultural plants

    Full Text Available Water productivity index is one of the main factors in efficient use of water for agricultural products. In this study, the rate of water productivity (WP in six irrigated tea fields and three rainfed (no irrigation were assessed by farmer’s management for two years (2009-2010. Yield of each tea field in successive harvests, soil moisture monitoring by gravimetric soil and use of water balance equation was conducted during the growing seasons. Volume of water entered to irrigation system and amount of water reached to surface level were also measured. Tea mean yield in irrigated and rainfed field were 2843 and 1095 Kg. ha-1, respectively. Average of gross irrigation and effective rainfall (WP and irrigation water productivity (IWP in the irrigated fields were 4.39 and 4.55 kg (made tea ha-1 mm-1 and average of net WP (actual evaportanspiration and net IWP was 5.18 and 6.61 kg ha-1 mm-1, respectively. Average WP in rainfed tea fields was 3.4 kg ha-1 for each mm of effective rainfall. The most effective factors on WP reduction in tea fields were improper harvesting operations (un standard plucking and economic problems. Moreover, improper operation and maintenance and old irrigation systems and unprincipled irrigation scheduling in irrigated tea fields were also effective on WP reduction. Comparing the results of this study with other studies in past, showed that by implementing the proper methods in irrigation management and appropriate agricultural practices can improve water productivity in tea fields.

    With global population projected to approach 9 billion by 2050, it has been estimated that a 40% increase in cereal production will be required to satisfy the worlds growing nutritional demands. Any such increases in agricultural productivity are likely to occur within a system that has limited room for growth and in a world with a climate that is different from that of today. Fundamental to achieving food and water security, is the capacity to monitor the health and condition of agricultural systems. While space-agency based satellites have provided the backbone for earth observation over the last few decades, many developments in the field of high-resolution earth observation have been advanced by the commercial sector. These advances relate not just to technological developments in the use of unmanned aerial vehicles (UAVs), but also the advent of nano-satellite constellations that offer a radical shift in the way earth observations are now being retrieved. Such technologies present opportunities for improving our description of the water, energy and carbon cycles. Efforts towards developing new observational techniques and interpretative frameworks are required to provide the tools and information needed to improve the management and security of agricultural and related sectors. These developments are one of the surest ways to better manage, protect and preserve national food and water resources. Here we review the capabilities of recently deployed satellite systems and UAVs and examine their potential for application in precision agriculture.

    The electron-beam process is one of the most effective methods for removing SO 2 and NO X from industrial flue gases and producing a usable by-product. This paper surveys the potential for production and consumption of alternative, usable, commercial by-products, in conjunction with major reductions in the inventory of emissions of SO 2 and NO X . An examination is made of the important limitations in the annual consumptive use or price of and/or net revenues from commonplace, electric utility, by-product types such as gypsum, sulfuric acid, etc. A principal focus of the work is an analysis and quantification of the major large-scale, growing and profitable markets for utility solid wastes that can be generated in agricultural fertilizer forms, including ammonium sulfate and other compounds that are available through stack-gas cleaning operations at large, coal-fired boilers. Cost study data is arranged to define the impact of commercial by-product yield and revenue on the economics of full scale SO 2 and NO X emission reduction activity. (author)

    Full Text Available In this paper, we take the establishment of Poyang Lake Eco-Economic Zone in 2009 as a quasi-natural experiment, to evaluate its influence on the agricultural labor productivity in Jiangxi Province, China. The estimation results of the DID method show that the establishment of the zone reduced agricultural labor productivity by 3.1%, lowering farmers’ net income by 2.5% and reducing the agricultural GDP by 3.6%. Furthermore, this negative effect has increased year after year since 2009. However, the heterogeneity analysis implies that the agricultural labor productivities of all cities in Jiangxi Province will ultimately converge. We find that the lack of agricultural R&D activities and the abuse of chemical fertilizers may be the main reasons behind the negative influence of the policy, by examining two possible transmission channels—the R&D investment and technological substitution. Corresponding policy implications are also provided.

    Production of food crops on metal contaminated agricultural soils is of concern because consumers are potentially exposed to hazardous metals via dietary intake of such crops or crop derived products. Therefore, the current study was conducted to develop management protocols for crop cultivation to allow safer food production. Metal uptake, as influenced by pH change-induced immobilizing agents (dolomite, steel slag, and agricultural lime) and sorption agents (zeolite and compost), was monitored in three common plants representative of leafy (Chinese cabbage), root (spring onion) and fruit (red pepper) vegetables, in a field experiment. The efficiency of the immobilizing agents was assessed by their ability to decrease the phytoavailability of metals (Cd, Pb, and Zn). The fruit vegetable (red pepper) showed the least accumulation of Cd (0.16-0.29 mgkg(-1) DW) and Pb (0.2-0.9 mgkg(-1) DW) in edible parts regardless of treatment, indicating selection of low metal accumulating crops was a reasonable strategy for safer food production. However, safer food production was more likely to be achievable by combining crop selection with immobilizing agent amendment of soils. Among the immobilizing agents, pH change-induced immobilizers were more effective than sorption agents, showing decreases in Cd and Pb concentrations in each plant well below standard limits. The efficiency of pH change-induced immobilizers was also comparable to reductions obtained by 'clean soil cover' where the total metal concentrations of the plow layer was reduced via capping the surface with uncontaminated soil, implying that pH change-induced immobilizers can be practically applied to metal contaminated agricultural soils for safer food production.

    In Morocco, rainfed agriculture is practiced in the majority of agricultural land. However, the intensive land use coupled to the irregular rainfall constitutes a serious threat that affect country's food security. Conservation agriculture (CA) represents a promising alternative to produce more and sustainably. In fact, the direct seeding showed high yield in arid regions of Morocco but its extending to other more humid agro-ecological zones (rainfall > 350mm) remains scarce. In order to promote CA in Morocco, differents trials have been installed in central plateau of Morocco, to compare CA to conventional tillage (CT). The yields of the main practiced crops (wheat, lentil and checkpea) under CA and CT were analyzed and compared in the 3 soils types (Vertisol, Cambisol and Calcisol). Also, we studied the effect of CA on soil organic matter (SOM) and soil losses (SL) in the 3 different sites. The APSIM model was used to model the long term impact of CA compared to CT. The results obtained in this research have shown favorable effects of CA on crop production, SOM and soil erosion. Key words: Conservation agriculture, yield, soil properties, modeling, APSIM, Morocco.

    To feed the increasing world population, more food needs to be produced from agricultural land systems. Solutions to produce more food with fewer resources while minimizing adverse environmental and ecological consequences require sustainable agricultural land use practices as supplementary to advanced biotechnology and agronomy. This review paper, from a land system perspective, systematically proposed and analyzed three interactive strategies that could possibly raise future food production under global change. By reviewing the current literatures, we suggest that cropland expansion is less possible amid iferce land competition, and it is likely to do less in increasing food production. Moreover, properly allocating crops in space and time is a practical way to ensure food production. Climate change, dietary shifts, and other socio-economic drivers, which would shape the demand and supply side of food systems, should be taken into consideration during the decision-making on rational land management in respect of sustainable crop choice and allocation. And ifnally, crop-speciifc agricultural intensiifcation would play a bigger role in raising future food production either by increasing the yield per unit area of individual crops or by increasing the number of crops sown on a particular area of land. Yet, only when it is done sustainably is this a much more effective strategy to maximize food production by closing yield and harvest gaps.

    Approximately 70% of global available freshwater supplies are used in the agricultural sector. Increased demands for water to meet growing population food requirements, and expected changes in the reliability of freshwater supplies due to climate change, threaten the sustainability of water supplies worldwide - not only on farms, but in connected cities and industries. Researchers concerned with agricultural water use sustainability use a variety of theoretical and empirical measures of efficiency and productivity to gain insight into the sustainability of agricultural water use. However, definitions of measures, or indices, vary between different natural and political boundaries, across regions, states and nations and between their respective research, industry, and environmental groups. Index development responds to local data availability and local agendas, and there is debate about the validity of various indices. However, real differences in empirical index measures are not well-understood across the multiple disciplines that study agricultural water use, including engineering and hydrology, agronomy, climate and soil sciences, and economics. Nevertheless reliable, accessible, and generalizable indices are required for planners and policymakers to promote sustainable water use systems. This study synthesizes a set of water use efficiency and productivity indices based on academic, industry and government literature in California and Australia, two locations with similarly water-stressed and valuable agricultural industries under pressure to achieve optimal water use efficiency and productivity. Empirical data at the irrigation district level from the California San Joaquin Valley and Murray Darling Basin states of Victoria and New South Wales in Australia are used to compute indices that estimate efficiency, yield productivity, and economic productivity of agricultural water use. Multiple index estimates of same time-series data demonstrate historical spread

    Biohydrogen production research was carried out using raw materials of agricultural organic waste that was obtained from markets around the Bandung city. The organic part, which consisted of agricultural waste material, mainly fruit and vegetable waste, was crushed and milled using blender. The sludge that produced from milling process was then used as a substrate for mixed culture microorganism as a raw material to produce biohydrogen. As much as 1.2 kg.day-1 of sludge (4% of total solid) was fed into bioreactor that had a capacity of 30L. Experiment was done under anaerobic fermentation using bacteria mixture culture that maintained at pH in the range of 5.6-6.5 and temperature of 25-30oC on semi-continuous mode. Parameters of analysis include pH, temperature, total solid (TS), organic total solid (OTS), total gas production, and hydrogen gas production. The results showed that from 4% of substrate resulted 897.86 L of total gas, which contained 660.74 L (73.59%) of hydrogen gas. The rate of hydrogen production in this study was 11,063 mol.L-1.h-1.

  7. Partitioning of evapotranspiration using a stable isotope technique in an arid and high temperature agricultural production system

    Agricultural production in the hot and arid low desert systems of southern California relies heavily on irrigation. A better understanding of how much and to what extent irrigated water is transpired by crops relative to being lost through evaporation would improve the management of increasingly limited water resources. In this study, we examined the partitioning of evapotranspiration (ET) over a field of forage sorghum (Sorghum bicolor), which was under evaluation as a potential biofuel feedstock, based on isotope measurements of three irrigation cycles at the vegetative stage. This study employed customized transparent chambers coupled with a laser-based isotope analyzer to continuously measure near-surface variations in the stable isotopic composition of evaporation (E, δ), transpiration (T, δ) and ET (δ) to partition the total water flux. Due to the extreme heat and aridity, δ and δ were very similar, which makes this system highly unusual. Contrary to an expectation that the isotopic signatures of T, E, and ET would become increasingly enriched as soils became drier, our results showed an interesting pattern that δ, δ, and δ increased initially as soil water was depleted following irrigation, but decreased with further soil drying in mid to late irrigation cycle. These changes are likely caused by root water transport from deeper to shallower soil layers. Results indicate that about 46% of the irrigated water delivered to the crop was used as transpiration, with 54% lost as direct evaporation. This implies that 28 − 39% of the total source water was used by the crop, considering the typical 60 − 85% efficiency of flood irrigation. The stable isotope technique provided an effective means of determining surface partitioning of irrigation water in this unusually harsh production environment. The results suggest the potential to further minimize unproductive water losses in these production systems.

    Full Text Available Degraded agricultural lands in the arid tropics have low soil organic carbon (SOC and hence low productivity. Poor farmers that their livelihoods depend highly on these types of lands are suffering. Cropping strategies that are able to improve the soil productivity are needed. In the present study, some intercropping models of food crops with bio-energy crop of castor (Ricinus communis L. were tested to assess their potential to improve the degraded land productivity. The intercropping models were: (1 castor - hybrid maize, (2 castor – short season maize, (3 castor – mungbean, and (4 castor –short season maize – mungbean. The results show that yields of the component crops in monoculture were relatively the same as in intercropping, resulted in a high Land Equivalent Ratio (LER. The highest LER (3.07 was calculated from intercropping castor plants with short season maize crops followed by mungbean with intercropping productivity of IDR 15,097,600.00 ha-1. Intercropping has a great potential to improve degraded agriculture land productivity and castor is a promising plant to improve biodiversity and area coverage on the land.

    Food security has always been a focus issue in China. Farmland consolidation (FC) was regarded as a critical way to increase the quantity and improve the quality of farmland to ensure food security by Chinese government. FC projects have been nationwide launched, however few studies focused on evaluating the effectiveness of FC at a national scale. As such, an efficient way to evaluate the effectiveness of FC on improving agricultural productivity in China will be needed and it is critical for future national land consolidation planning. In this study, we selected 7505 FC projects completed between 2006 and 2013 with good quality Normalized Difference Vegetation Index (NDVI) as samples to evaluate the effectiveness of FC. We used time-series Moderate Resolution Imaging Spectroradiometer NDVI from 2001 to 2013, to extract four indicators to characterize agricultural productivity change of 4442 FC projects completed between 2006 and 2010, i.e., productivity level (PL), productivity variation (PV), productivity potential (PP), and multi-cropping index (MI). On this basis, we further predicted the same four characteristics for 3063 FC projects completed between 2011 and 2013, respectively, using Support Vector Machines (SVM). We found FC showed an overall effective status on improving agricultural productivity between 2006 and 2013 in China, especially on upgrading PL and improving PP. The positive effect was more prominent in the southeast and eastern China. It is noteworthy that 27.30% of all the 7505 projects were still ineffective on upgrading PL, the elementary improvement of agricultural productivity. Finally, we proposed that location-specific factors should be taken into consideration for launching FC projects and diverse financial sources are also needed for supporting FC. The results provide a reference for government to arrange FC projects reasonably and to formulate land consolidation planning in a proper way that better improve the effectiveness of FC.

    The genus Aspergillus is one of the most important filamentous fungal genera. Aspergillus species are used in the fermentation industry, but they are also responsible of various plant and food secondary rot, with the consequence of possible accumulation of mycotoxins. The aflatoxin producing A....... flavus and A. parasiticus, and ochratoxinogenic A. niger, A. ochraceus and A. carbonarius species are frequently encountered in agricultural products. Studies on the biodiversity of toxigenic Aspergillus species is useful to clarify molecular, ecological and biochemical characteristics of the different...... occurring in agricultural fields. Altogether nine different black Aspergillus species can be found on grapes which are often difficult to identify with classical methods. The polyphasic approach used in our studies led to the identification of three new species occurring on grapes: A. brasiliensis, A...

    We present paleoeconomy reconstructions for premodern agriculture, selecting, wherever required, features and parameter values specific for the Cucuteni-Trypillia cultural unity (CTU; 5,400-2,700 BC, mostly the territory of modern Ukraine, Moldova, and Romania). We verify the self-consistency and viability of the archaeological evidence related to all major elements of the agricultural production cycle within the constraints provided by environmental and technological considerations. The starting point of our analysis is the paleodiet structure suggested by archaeological data, stable isotope analyses of human remains, and palynology studies in the CTU area. We allow for the archeologically attested contributions of domesticated and wild animal products to the diet, develop plausible estimates of the yield of ancient cereal varieties cultivated with ancient techniques, and quantify the yield dependence on the time after initial planting and on rainfall (as a climate proxy). Our conclusions involve analysis of the labor costs of various seasonal parts of the agricultural cycle of both an individual and a family with a majority of members that do not engage in productive activities that require physical fitness, such as tillage. Finally, we put our results into the context of the exploitation territory and catchment analysis, to project various subsistence strategies into the exploitation territory of a farming settlement. The simplest economic complex based on cereals and domestic and wild animal products, with fallow cropping, appears to be capable of supporting an isolated, relatively small farming settlement of 50-300 people (2-10 ha in area) even without recourse to technological improvements such as the use of manure fertilizer. Our results strongly suggest that dairy products played a significant role in the dietary and labor balance. The smaller settlements are typical of the earliest Trypillia A stage but remain predominant at the later stages. A larger

    The linear relationships between energy prices and prices for agricultural commodities such as corn and soybeans may have been affected, over the last several years, by policy legislations in the farm sector, the Energy Independence and Security Act of 2007, and the Renewable Fuel Standard Program for 2014. Using high-frequency data and newer methodology, this study investigates dependence between agricultural commodity futures prices and energy futures prices. Results reveal that agricultural commodity and energy future prices are highly correlated and exhibit positive and significant relationship. Findings from this study highlight that an increase in energy price increases the price of agricultural commodities. - Highlights: • Energy policy mandates production of 15 billion gallons of corn ethanol by 2015. • Energy-intensive agriculture has a link between energy sector and crop production costs. • We investigate correlation between energy prices and agricultural commodity prices. • Agricultural commodity and energy future prices are highly correlated. • Increase in energy price increases the price of agricultural commodity

    The residue of pesticide has posed a serious threat to human health. Fast, broad-spectrum detection methods are necessary for on-site screening of various types of pesticides. With citrate-coated Au nanoparticles (Au NPs) as colorimetric probes, a visual and spectrophotometric method for rapid assay of cartap, which is one of the most important pesticides in agriculture, is reported for the first time. Based on the color change of Au colloid solution from wine-red to blue resulting from the aggregation of Au NPs, cartap could be detected in the concentration range of 0.05-0.6 mg/kg with a low detection limit of 0.04 mg/kg, which is much lower than the strictest cartap safety requirement of 0.1 mg/kg. Due to the limited research on the rapid detection of cartap based on Au NPs, the performance of the present method was evaluated through aggregation kinetics, interference influence, and sample pretreatment. To further demonstrate the selectivity and applicability of the method, cartap detection is realized in cabbage and tea with excellent analyte concentration recovery. These results demonstrate that the present method provides an easy and effective way to analyze pesticide residue in common products, which is of benefit for the rapid risk evaluation and on-site screening of pesticide residue.

    2010-01-01

    Water stresses on agricultural crops during critical phases of crop phenology (such as grain filling) has higher impact on the eventual yield than at other times of crop growth. Therefore farmers are more concerned about water stresses in the context of crop phenology than the meteorological droughts. However the drought estimates currently produced do not account for the crop phenology. US Department of Agriculture (USDA) and National Oceanic and Atmospheric Administration (NOAA) have developed a drought monitoring decision support tool: The U.S. Drought Monitor, which currently uses meteorological droughts to delineate and categorize drought severity. Output from the Drought Monitor is used by the States to make disaster declarations. More importantly, USDA uses the Drought Monitor to make estimates of crop yield to help the commodities market. Accurate estimation of corn yield is especially critical given the recent trend towards diversion of corn to produce ethanol. Ethanol is fast becoming a standard 10% ethanol additive to petroleum products, the largest traded commodity. Thus the impact of large-scale drought will have dramatic impact on the petroleum prices as well as on food prices. USDA's World Agricultural Outlook Board (WAOB) serves as a focal point for economic intelligence and the commodity outlook for U.S. WAOB depends on Drought Monitor and has emphatically stated that accurate and timely data are needed in operational agrometeorological services to generate reliable projections for agricultural decision makers. Thus, improvements in the prediction of drought will reflect in early and accurate assessment of crop yields, which in turn will improve commodity projections. We have developed a drought assessment tool, which accounts for the water stress in the context of crop phenology. The crop modeling component is done using various crop modules within Decision Support System for Agrotechnology Transfer (DSSAT). DSSAT is an agricultural crop

    The ongoing drought in California has substantially reduced surface water supplies for millions of acres of irrigated farmland in California's Central Valley. Rapid assessment of drought impacts on agricultural production can aid water managers in assessing mitigation options, and guide decision making with respect to requests for local water transfers, county drought disaster designations, and allocation of emergency funds to mitigate drought impacts. Satellite remote sensing offers an efficient way to provide quantitative assessments of drought impacts on agricultural production and increases in idle acreage associated with reductions in water supply. A key advantage of satellite-based assessments is that they can provide a measure of land fallowing that is consistent across both space and time. We describe an approach for monthly and seasonal mapping of uncultivated agricultural acreage developed as part of a joint effort by USGS, USDA, NASA, and the California Department of Water Resources to provide timely assessments of land fallowing during drought events. This effort has used the Central Valley of California as a pilot region for development and testing of an operational approach. To provide quantitative measures of uncultivated agricultural acreage from satellite data early in the season, we developed a decision tree algorithm and applied it to timeseries of data from Landsat TM, ETM+, OLI, and MODIS. Our effort has been focused on development of indicators of drought impacts in the March - August timeframe based on measures of crop development patterns relative to a reference period with average or above average rainfall. To assess the accuracy of the algorithms, monthly ground validation surveys were conducted across 640 fields from March - September, 2014. We present the algorithm along with updated results from the accuracy assessment, and discuss potential applications to other regions.

    Full Text Available The expansion of the European Union during the 1980s with the Mediterranean region countries was a major challenge both for the new Member States and for the Community as a whole. The new Member States, i.e. Greece, Spain and Portugal, were poorly developed in economic terms, with a high proportion of the agricultural sector in overall production and employment structure. Still, the concerns about the future turned out to be unfounded, and the impulse of the accession process and the necessity to compete on the common market brought certain advantages both to existing and to new Member States, thus enforcing certain changes in the structure of production and employment in the economies discussed in this paper. Today, the Mediterranean region states, irrespective of the success achieved in the past years, are again facing the need to resolve certain important economic problems related to the global fi nancial crisis. This paper discusses one of the aspects that strongly contributes to the present diffi cult socioeconomic situation of the contemplated region, i.e. evolution of the sectoral structure of employment and GDP during the European Union membership, with special consideration of the situation in agriculture

    Over the past decade, the World Bank has become the leading international institution for development financing and for elaborating new development strategies. This has involved a major shift in lending toward agriculture and rural development. Explanations for the change range from more progressive expertise within the Bank to the shock of the 1972-74 food crisis and renewed penetration of Third World agriculture by capitalist agribusiness. Discriminating among these perspectives requires attention to the core issue of the relationship between increasing food production and reducing rural poverty. The author feels that the issue is irreducibly political and that the Bank's record is less encouraging than the reformist rhetoric. 33 references, 4 tables.

    Soil-crop simulator model is an effective tool for providing decision on agricultural management. APSIM (Agricultural Production Systems Simulator) was developed to simulate the biophysical process in farming system, and particularly in the economic and ecological features of the systems under climatic risk. The current literatures revealed that APSIM could be applied in wide zone, including temperate continental, temperate maritime, sub-tropic and arid climate, and Mediterranean climates, with the soil type of clay, duplex soil, vertisol, silt sandy, silt loam and silt clay loam. More than 20 crops have been simulated well. APSIM is powerful on describing crop structure, crop sequence, yield prediction, and quality control as well as erosion estimation under different planting pattern.

    Random fluctuations in temperature and precipitation have substantial impacts on agricultural output. However, the contribution of these changing configurations in weather to total factor productivity (TFP) growth has not been addressed explicitly in econometric analyses. Thus, the key objective of this study is to quantify and to investigate the role of changing weather patterns in explaining yearly fluctuations in TFP. For this purpose, we define TFP to be a measure of total output divided by a measure of total input. We estimate a stochastic production frontier model using U.S. state-level agricultural data incorporating growing season temperature and precipitation, and intra-annual standard deviations of temperature and precipitation for the period 1960-2004. We use the estimated parameters of the model to compute a TFP index that has good axiomatic properties. We then decompose TFP growth in each state into weather effects, technological progress, technical efficiency, and scale-mix efficiency changes. This approach improves our understanding of the role of different components of TFP in agricultural productivity growth. We find that annual TFP growth averaged 1.56% between 1960 and 2004. Moreover, we observe substantial heterogeneity in weather effects across states and over time.

    The importance of food from different production systems to the internal dose from radiocesium, was investigated in selected study sites in Ukraine and Russia. Food products from semi-natural ecosystems are major contributors to the individual internal dose to rural population in areas affected by the Chernobyl accident. At the selected study sites it is estimated in 1995 that foods from private farms and forests contribute on average 35% to 60%, to the individual internal dose, variation relating to soil types and implemented countermeasures. The importance of food products from private farms and particularly forest products increases with time since Cs concentration in some of the natural food products have longer ecological half life than food products from agricultural systems. A significant relationship was observed between consumption of mushrooms and whole body content of radiocesium in rural people. The contribution to the collective dose of food products produced in the semi-natural ecosystems is less than the contribution to the individual internal dose for the local rural population

    Full Text Available Green agriculture can improve biodiversity, increase farmers’ income, reduce agricultural non-point source pollution, solve food safety issues, and will be an important way to promote sustainable development in China. At present, the green transformation of China’s agriculture has encountered a bottleneck in the development of a green agricultural product market. How to develop a green agricultural product market has become an issue worthy of in-depth study in the academia. Previous studies have already given persuasive explanations for the inability to form a green agricultural product market, but few have explored its development path from the angle of cooperation. By employing the method of a Transferable Utilities (TU cooperative game, and based on theoretical analyses and hypothetical data, this thesis aims to prove the effectiveness of the multilateral coalition to develop the green agricultural product market in China. The results show the effectiveness of the developed model of the green agricultural product market in which producers, consumers, food safety inspection departments, and e-commerce platforms cooperate with each other. This model meets the objective needs of the times and that of the market economy. According to the marginal contribution value of participants in different coalition orders, this thesis finds 6 kinds of coalition orders. When producers and consumers of green agricultural products enter the coalition in the last place, the marginal contribution value is maximized, which reflects the importance of the supply side and demand side of green agricultural products. In other words, the development of the green agricultural product market is a dynamic process—determined by consumers and promoted by producers—in which both sides promote and restrict each other. Finally, this article presents two policy recommendations: at the national level, to clearly proposes a strategy to build a green agricultural product e

    1991-01-01

    The electron-beam process is one of the most effective methods for removing SO 2 and NO x from industrial flue gases and producing a usable by-product. This flue gas treatment consists of adding a small amount of ammonia to the flue gas and irradiating the gas by means of an electron beam. This causes reactions which convert SO 2 and NO x to ammonium sulfate and ammonium nitrate. These salts are then collected from the flue gas by conventional collectors, such as a baghouse or electrostatic precipitator. This paper will describe the potential for production of the fertilizer and will analyze the market potential and consumption of the by-product. A principal focus of the work is an analysis and quantification of the major large-scale, growing and profitable markets for utility solid wastes that can be generated in the form of agricultural fertilizer. Cost study data is arranged to define the impact of commercial by-product field and revenue on the economics of full scale SO 2 and NO x emission reduction activity

    Analyses of soils, irrigation waters, agriculture products (lettuce), green pasture, and cheese were performed in samples collected in the area of the old Urgeirica uranium mine and milling facilities, Centre-North of Portugal, in order to assess the transfer of uranium series radionuclides in the environment and to man. Soils close to milling tailings display an enhancement of radioactivity. In the drainage basin of the stream Ribeira da Pantanha, receiving drainage from the tailings piles and discharges from the acid mine water treatment plant, there was enhancement of uranium series radionuclide concentrations in water and suspended matter. Agriculture products from kitchen gardens irrigated with water from the Ribeira da Pantanha show an increase of radioactivity, mainly due to uranium isotopes. Agriculture products from other kitchen gardens in this area, irrigated with groundwater, as well pasture and cheese produced locally from sheep milk did not show enhanced radionuclide concentrations. In the Urgeirica area, some soils display radionuclide concentrations higher than soils in reference areas and, in agriculture products grown there, 226 Ra was the radionuclide more concentrated by vegetables. Through ingestion of these products 226 Ra may be the main contributor to the increment of radiation dose received by local population. (author)

    The application of agricultural nuclear techniques constitutes one essential component of new and high technologies in agriculture. It has contributed significantly to sustainable development of agricultural production. By using radiation or in combination with related techniques and focusing on the selections of new strains with better quality, higher yield, stronger resistance or tolerance, China has obtained 513 new varieties of more than 40 species of plants. New mutagens such as ion beam, low magnetic treatment and space mutation have been developed in mutation breeding and achieved a batch of outstanding mutants and varieties. Recent work has laid more emphasis on selection and improvement of crop plants and high value horticultural plants with superior quality traits. Some innovative mutation technologies have been proposed and recommended as technical guideline in mutation practices. China has approved 18 kinds of irradiated agricultural products and foods and six national hygiene standards on six classes of irradiated foods. The annual irradiated foods and agricultural products are undergoing rapid growth in past years and reached 80 thousand tons in 1999. Nuclear technique and related techniques are widely used in soil and fertility management, agrochemical pollution, soil erosion, animal nutrition, productivity and diagnosis of disease. Remarkable social and economic benefits have been achieved in reasonable utilization of agricultural resource, animal health and production. Sterile insect technique has been studied in the control of a variety of pest insects and has provided feasible technology packages for the control of harmful insects. Finally, the authors have made a comprehensive perspective on the role and potential application of nuclear techniques in addressing main agricultural problems.

    The Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC; Christensen et al 2007) has, with greater confidence than previous reports, warned the international community that the increase in anthropogenic greenhouse gases emissions will result in global climate change. One of the most direct and threatening impacts it may have on human societies is the potential consequences on global crop production. Indeed agriculture is considered as the most weather-dependent of all human activities (Hansen 2002) since climate is a primary determinant for agricultural productivity. The potential impact of climate change on crop productivity is an additional strain on the global food system which is already facing the difficult challenge of increasing food production to feed a projected 9 billion people by 2050 with changing consumption patterns and growing scarcity of water and land (Beddington 2010). In some regions such as Sub-Saharan Africa or South Asia that are already food insecure and where most of the population increase and economic development will take place, climate change could be the additional stress that pushes systems over the edge. A striking example, if needed, is the work from Collomb (1999) which estimates that by 2050 food needs will more than quintuple in Africa and more than double in Asia. Better knowledge of climate change impacts on crop productivity in those vulnerable regions is crucial to inform policies and to support adaptation strategies that may counteract the adverse effects. Although there is a growing literature on the impact of climate change on crop productivity in tropical regions, it is difficult to provide a consistent assessment of future yield changes because of large uncertainties in regional climate change projections, in the response of crops to environmental change (rainfall, temperature, CO2 concentration), in the coupling between climate models and crop productivity functions, and in the adaptation of

    A participatory watershed management approach is one of the tested, sustainable and eco-friendly options to upgrade rain-fed agriculture to meet growing food demand along with additional multiple benefits in terms of improving livelihoods, addressing equity issues and biodiversity concerns. Watershed interventions at study sites in Thailand (Tad Fa and Wang Chai) and India (Kothapally) effectively reduced runoff and the associated soil loss. Such interventions at Xiaoxincun (China) and Wang Chai improved groundwater recharging and availability. Enhanced productive transpiration increased rainwater use efficiency for crop production by 13-29% at Xiaoxincun; 13-160% at Lucheba (China), 32-37% at Tad Fa and 23-46% at Wang Chai and by two to five times at Kothapally. Watershed interventions increased significantly the additional net returns from crop production as compared with the pre-watershed intervention period. Increased water availability opened up options for crop diversification with high-value crops, including increased forage production and boosted livestock-based livelihoods. In dryland tropics, integrated watershed management approach enabled farmers to diversify the systems along with increasing agricultural productivity through increased water availability, while conserving the natural resource base. Household incomes increased substantially, leading to improved living and building the resilience of the community and natural resources. Copyright © 2011 Society of Chemical Industry.

    The sustainability of biofuel expansion is strongly dependent on the environmental footprint of feedstock production, including both direct impacts within feedstock-producing areas and potential leakage effects due to disruption of existing food, feed, or fiber production. Assessing and minimizing these impacts requires novel methods compared to traditional supply chain lifecycle assessment. When properly validated and applied at appropriate spatial resolutions, biogeochemical process models are useful for simulating how the productivity and soil greenhouse gas fluxes of cultivating both conventional crops and advanced feedstock crops respond across gradients of land quality and management intensity. In this work we use the DayCent model to assess the biogeochemical impacts of agricultural residue collection, establishment of perennial grasses on marginal cropland or conservation easements, and intensification of existing cropping at high spatial resolution across several real-world case study landscapes in diverse US agricultural regions. We integrate the resulting estimates of productivity, soil carbon changes, and nitrous oxide emissions with crop production budgets and lifecycle inventories, and perform a basic optimization to generate landscape cost/GHG frontiers and determine the most practical opportunities for low-impact feedstock provisioning. The optimization is constrained to assess the minimum combined impacts of residue collection, land use change, and intensification of existing agriculture necessary for the landscape to supply a commercial-scale biorefinery while maintaining exiting food, feed, and fiber production levels. These techniques can be used to assess how different feedstock provisioning strategies perform on both economic and environmental criteria, and sensitivity of performance to environmental and land use factors. The included figure shows an example feedstock cost-GHG mitigation tradeoff frontier for a commercial-scale cellulosic

    Full Text Available The first part of the paper deals with the influence of individual commodities on the profitability and risks of farms. Production structure was given thought share of twelve basic crops in total agricultural production yield. Volume of accumulated profit for five-year income was chosen as viability criterion. The research did not show that specialization in one of the commodities had significantly influenced achieved profitability. The only exception is the production of milk, which clearly lead to lower profitability. Production structure determined the risk of farms. Farms were constantly threatened by both negative profitability, and also steep fluctuations of cash flow (in other of long-term positive profitability, leading to temporary loss of solvency. The analysis showed that different types of production structures lead to different types of threats. The probability of falling into production losses, or that the loss is so great that not even cover variable costs (a farm finds itself under the point of termination of production was calculated using the EaR method. The results again supported previous findings. Loss is highly likely to be achieved in commodities of animal production. For commodities of crop production the probability of loss was roughly a half, but the probability of exceeding a period of variable costs is higher.

    The treatment of agriculture and food products with ionizing radiation has been proven to be safe, effective, economical, and according to consumer surveys, the end product is better. However, commercial implementation of food irradiation has been slow because of the following: the lack of profit incentives; the failure of the political system to deal with antinuclear groups; the failure of public health authorities to actively support this technology. Food irradiation cannot be considered successfully implemented until the commercial industry is making a profit by the use of this technology. Use of this technology will: (1) reduce food borne infections (FBI); (2) decrease the hazards of the use of antibiotics in livestock and poultry production; (3) reduce the need for agriculture quarantine procedures; and (4) increase shelf-life of perishable foods. However, only (1) and (3) are being considered as economic alternatives by the present day's food industry. Previously, agriculture has focused on technology that would increase production and reduce costs. Today this is rapidly changing to implementing technology that markets a product the consumer wants and is perceived as being safer and environmentally responsible. (author)

  19. Guide for dosimetry in radiation research on food and agricultural products

    International Nuclear Information System (INIS)

    2002-01-01

    This guide covers the minimum requirements for dosimetry and absorbed-dose validation needed to conduct research on the irradiation of food and agricultural products. Such research includes establishment of the quantitative relationship between the absorbed dose and the relevant effects in these products. This guide also describes the overall need for dosimetry in such research, and in reporting of the results. This guide is intended for use by research scientists in the food and agricultural communities, and not just scientists conducting irradiation research. It, therefore, includes more tutorial information than most other ASTM and ISO/ASTM dosimetry standards for radiation processing. This guide is in no way intended to limit the flexibility of the experimenter in the experimental design. However, the radiation source and experimental set up should be chosen such that the results of the experiment will be beneficial and understandable to other scientists, regulatory agencies, and the food and agricultural communities. The effects produced by ionizing radiation in biological systems depend on a large number of factors which may be physical, physiological, or chemical. Although not treated in detail in this guide, quantitative data of environmental factors that may affect the absorbed-dose response of dosimeters, such as temperature and moisture content in the food or agricultural products should be reported. The overall uncertainty in the absorbed-dose measurement and the inherent absorbed-dose range within the specimen should be taken into account in the design of an experiment. The guide covers research conducted using the following types of ionizing radiation: gamma rays, bremsstrahlung X-rays, and electron beams. This guide does not include other aspects of radiation processing research, such as planning of the experimental design. Dosimetry must be considered as an integral part of the experimental design. The guide does not include dosimetry for irradiator

    Many researches showed that climate change has significant impact on agricultural sector, which threats the food security especially in developing countries. It has been observed also that the climate change increases the intensity of extreme events. This research investigated the impact climate to the agricultural productivity in East Java, as one of the main rice producers in Indonesia. Standard regression as well as panel regression models have been performed in order to find the best model which is able to describe the climate change impact. The analysis found that the fixed effect model of panel regression outperforms the others showing that climate change had negatively impacted the rice productivity in East Java. The effect in Malang and Pasuruan were almost the same, while the impact in Sumenep was the least one compared to other districts.

    Full Text Available This paper is dedicated to the directions of development of rural areas, primarily agricultural areas of the Podlaskie voivodeship, which in light of current criteria has been qualified almost entirely as problem area (ONW. Results presented are culmination of research related to issues of problem areas primarily in the area of the Podlaskie voivodeship by the author of the herewith paper during last few years. In conclusion to the results of the research it can be said that the primary direction of the development of rural areas in the Podlaskie voivodeship will be modern, large-scale farms able to adjust to current conditions, in particular environmental and soil conditions. In problem areas these will be mostly farms focusing on production of cattle and milk, developing production based on very high share of grassland areas. Complementary role in relation to conventional agriculture will be fulfilled by farms developing organic farming and agro-touristic farms. More intensive development of conventional tourism in rural areas can be expected once new tourism products and services have been developed. Assessment of the current economic development parameters of the Podlaskie voivodeship does not point at the convergence with other regions and possibility of decreasing the distance between the Podlaskie voivodeship and average results for Poland in the near future. However, some positive trends in terms of convergence with other regions in Poland can be observed in agriculture, primarily due to relatively good results in production of cattle and milk.

  3. Agricultural production and stability of settlement systems in Upper Mesopotamia during the Early Bronze Age (third millennium BCE)

    Science.gov (United States)

    Kalayci, Tuna

    This study investigates the relationship between rainfall variation and rain-fed agricultural production in Upper Mesopotamia with a specific focus on Early Bronze Age urban settlements. In return, the variation in production is used to explore stability of urban settlement systems. The organization of the flow of agricultural goods is the key to sustaining the total settlement system. The vulnerability of a settlement system increases due to the increased demand for more output from agricultural lands. This demand is the key for the success of urbanization project. However, without estimating how many foodstuffs were available at the end of a production cycle, further discussions on the forces that shaped and sustained urban settlement systems will be lacking. While large scale fluctuations in the flow of agricultural products between settlements are not the only determinants of hierarchical structures, the total available agricultural yield for each urban settlement in a hierarchy must have influenced settlement relations. As for the methodology, first, Early Bronze Age precipitation levels are estimated by using modern day associations between the eastern Mediterranean coastal areas and the inner regions of Upper Mesopotamia. Next, these levels are integrated into a remote-sensing based biological growth model. Also, a CORONA satellite imagery based archaeological survey is conducted in order to map the Early Bronze Age settlement system in its entirety as well as the ancient markers of agricultural intensification. Finally, ancient agricultural production landscapes are modeled in a GIS. The study takes a critical position towards the traditionally held assumption that large urban settlements (cities) in Upper Mesopotamia were in a state of constant demand for food. The results from this study also suggest that when variations in ancient precipitation levels are translated into the variations in production levels, the impact of climatic aridification on ancient

    Health risks associated to practical activities in farm and agriculture are increasing all over the world. These risks are depending from technology and chemicals substances abuse. Urban agriculture specifically constitutes a challenge for producers and researchers. Agricultural food production, held inside of the cities, looking for sustainable productions is developed in risky scenarios where it is possible to found environmental pollutants such as heavy metals. Environmental pollutants may to contaminate humans throughout different pathways. The analysis of factors related to agricultural working strategies of urban farm workers, the precedent knowledgement about production places and analytical data related to composition and properties of these sites, are significant criteria for proper management of ecosystems. Qualitative analysis research tool such as expert group criteria is a suitable method for field research in this area. It was determined that the precedent use of soil, the use of fertilizers and phytosanitary products are key elements to be taken into account for successful management of agroecosystems and for health risk prevention related to the possible influence of heavy metals in farm practice

    Agriculture is an important component of Canadian energy policy. There are many opportunities for both the production of energy from agricultural processes and the conservation of energy in agricultural production. These opportunities, as well as current practices and research in progress, are outlined in this report. Energy sources in agriculture include biomass (straw and other residues), methane production from manure, and oil and alcohol from crops. Alternate energy sources such as solar and wind power conserve conventional resources, and additional conservation opportunities exist in the use of greenhouses, waste heat and energy-efficient farming processes. Research programs and possible trends are outlined. 10 figs., 3 tabs.

    1992-09-01

    In order to develop small islands, not only must a vital agricultural system be maintained, but the range of opportunities for tourism must be increased with respect to both the seaside and the environmental features of the rural landscape. As an alternative to the traditional and economically declining ones, many innovative production processes can be identified, but their success depends on their interaction with the physical, biological, economic and social environment. In order to identify the main nodes and the most critical interactions, so as to increase the probability of success of a new productive process, a methodological approach based on the science of complexity is proposed for the cultivation of capers ( Capparis spinosa L.) on the island of Pantelleria. The methodology encompasses the identification of actors and factors involved. the quantitative evaluation of their interactions with the different stages of the productive process, and a quasiquantitative evaluation of the probability that the particular action will be performed successfully. The study of “traditional,” “modernized,” and “modernized-sustainable” processes, shows that the modernized-sustainable process offers mutually reinforcing opportunities in terms of an integrated development of high-quality agricultural products and the enhancement of environmental features, in conjunction with high-efficiency production techniques, in conjunction with high-efficiency production techniques, in a way that suits the development of Pantelleria. There is a high probability of failure, however, as a result of the large number of critical factors. Nevertheless, the present study indicates which activities will enhance the probability of successful innovation in the production process.

    Full Text Available In agriculture and forestry, the need to increase production and the simultaneous efforts to minimize the environmental impact of agricultural production processes and save costs find in sensor systems the best allied tool. The use of sensors helps exploit all available resources appropriately and to apply hazardous products moderately. When nutrients in the soil, humidity, solar radiation, density of weeds and a broad set of factors and data affecting the production are known, this situation improves and the use of chemical products such as fertilizers, herbicides and other pollutants can be reduced considerably. Part of this knowledge allows also monitoring photosynthetic parameters of high relevance for photosynthesis. Most of the associated activities fall within the scope of what it is called Precision Agriculture, an emerging area receiving special attention in recent years. [...

    In order to investigate and assess the pollution level of phthalic acid esters (PAEs) in farm soils and products from typical agricultural fields in areas of Zhongshan City, Guangdong Province, South China, 65 topsoil and 37 agricultural product samples were collected and contents of 6 PAEs compounds that classified by the U. S. Environmental Protection Agency (EPA) as priority pollutants were determined by the GC-FID. The results indicated that total contents of the PAEs (∑ PAEs) in soils ranged from 0. 14 to 1. 14 mg x kg(-1), and the mean value was 0.43 mg x kg(-1), with the detected ratio of 100%. Various concentrations of PAEs differed in three land-use types were ordered by vegetable soil > orchard soil > paddy soil. Comparing with six U.S. EPA priority pollutants of PAEs, the contents of Di-n-butyl phthalate (DBP) and Dimethyl phthalate ( DMP) in soils exceeded the control limits of PAEs in the American soil by 93.85% and 27.69% respectively, but the rest four PAEs compounds were lower than the control limits. Generally, the pollution level of soils contaminated by PAEs in agricultural fields of Zhongshan City was relatively low. The contents of 3 PAEs in agricultural products ranged from 0.15 to 3.15 mg x kg(-1) with the average of 1.12 mg x kg(-1), which was lower than the suggested standards in USA and Europe and with low health risk. Meanwhile, ∑ PAEs concentrations in vegetables were higher than those both in rice and fruits. DBP and DEHP were the main components of PAEs both in agricultural soils and products, with higher percentage contents and detected ratio. ∑ PAEs and DBP contents in various agricultural products-soils had a significantly positive correlation, with Pearson coefficients (r) in vegetables-vegetable soils were 0.81 (P = 0.000), 0.75 (P = 0.000), and corresponding r among rice-paddy soil and fruits-fruit soils were 0.74 (P = 0.036), 0.65 (P = 0.041) and 0.66 (P = 0.029), 0.78 (P = 0.045), respectively.

    Agricultural Agricultural waste of rice and wheat straws were studied for the production of protein and biomass. As these wastes have low protein contents as attempt is made to increase the protein and biomass content of these wastes so as to produce a better product for consumption as food. The studies were conducted using various media and various incubation periods. Some inorganic salts and molasses were added to improve the cultivation of fungi. Aspergillus oryzae produced the results due to its rapid growth which minimized the chance of contamination. Seven days incubation gave the most favourable results in both the agricultural wastes. The maximum production of biomass (33.33%) with a protein value of 20% was obtained with 450 g of rice straw in media no. 2 whereas 400 g of wheat straw on 6 litres of medium produced the best results with 20% biomass and a protein value of 20%.

    Two data libraries based on the 1974 US Census of Agriculture are described. The data packages (AGDATC and AGDATG) are available from the Radiation Shielding Information Center (RSIC), Oak Ridge National Laboratory, Oak Ridge, Tennessee 37831. Agricultural production and land-use information by county (AGDATC) or by 1/2 by 1/2 degree longitude-latitude grid cell (AGDATG) provide geographical resolution of the data. The libraries were designed for use in risk assessment models that simulate the transport of radionuclides from sources of airborne release through food chains to man. However, they are also suitable for use in the assessment of other airborne pollutants that can affect man from a food ingestion pathway such as effluents from synfuels or coal-fired power plants. The principal significance of the data libraries is that they provide default location-specific food-chain transport parameters when site-specific information are unavailable. Plant food categories in the data libraries include leafy vegetables, vegetables and fruits exposed to direct deposition of airborne pollutants, vegetables and fruits protected from direct deposition, and grains. Livestock feeds are also tabulated in four categories: pasture, grain, hay, and silage. Pasture was estimated by a material balance of cattle and sheep inventories, forage feed requirements, and reported harvested forage. Cattle (Bos spp.), sheep (Ovis aries), goat (Capra hircus), hog (Sus scrofa), chicken (Gallus domesticus), and turkey (Meleagris gallopavo) inventories or sales are also tabulated in the data libraries and can be used to provide estimates of meat, eggs, and milk production. Honey production also is given. Population, irrigation, and meteorological information are also listed

  14. Greater carbon stocks and faster turnover rates with increasing agricultural productivity

    2013-12-01

    H.H. Janzen (2006) eloquently argued that from an agricultural perspective there is a tradeoff between storing carbon as soil organic matter (SOM) and the soil nutrient and energy benefit provided during SOM mineralization. Here we report on results from the Permanent Rotation Trial at the Waite Agricultural Institute, South Australia, indicating that shifting to an agricultural management strategy which returns more carbon to the soil, not only leads to greater carbon stocks but also increases the rate of carbon cycling through the soil. The Permanent Rotation Trial was established on a red Chromosol in 1925 with upgrades made to several treatments in 1948. Decadal soil samples were collected starting in 1963 at two depths, 0-10 and 10-22.5 cm, by compositing 20 soil cores taken along the length of each plot. We have chosen to analyze five trials representing a gradient in productivity: permanent pasture (Pa), wheat-pasture rotation (2W4Pa), continuous wheat (WW), wheat-oats-fallow rotation (WOF) and wheat-fallow (WF). For each of the soil samples (40 in total), the radiocarbon activity in the bulk soil as well as size-fractionated samples was measured by accelerator mass spectrometry at ANU's Radiocarbon Dating Laboratory (Fallon et al. 2010). After nearly 70 years under each rotation, SOC stocks increased linearly with productivity data across the trials from 24 to 58 tC ha-1. Importantly, these differences were due to greater losses over time in the low productivity trials rather than gains in SOC in any of the trials. Uptake of the bomb-spike in atmospheric 14C into the soil was greatest in the trials with the greatest productivity. The coarse size fraction always had greater Δ14C values than the bulk soil samples. Several different multi-pool steady state and non-steady state models were used to interpret the Δ14C data in terms of SOC turnover rates. Regardless of model choice, either the decay rates of all pools needed to increase or the allocation of C to

    Full Text Available Although GM crops are cultivated on 175 million hectares in 27 countries, the regulation of agricultural biotechnology is in its becoming. In the future, many countries, of course, will lead to market biotech products, and the main focus will be biosafety issues for humans and the environment. Some countries have special regulatory mechanisms, others do not have the original national regulatory system, but their actions are under the provisions of international treaties for the production and handling of GM products. What are the main components of a strict but not stifling regulatory system? What are the disadvantages of existing systems? The article presents an overview of the state regulation systems of biotech agricultural products in the US, the EU, Argentina, South Africa and Brazil.

    Full Text Available Agriculture as one of the major economic sectors of Iran, has an important role in Gross Domestic Production by providing about 14% of GDP. This study attempts to forecast the value of the agriculture GDP using Periodic Autoregressive model (PAR, as the new seasonal time series techniques. To address this aim, the quarterly data were collected from March 1988 to July 1989. The collected data was firstly analyzed using periodic unit root test Franses & Paap (2004. The analysis found non-periodic unit root in the seasonal data. Second, periodic seasonal behavior (Boswijk & Franses, 1996 was examined. The results showed that periodic autoregressive model fits agriculture GDP well. This makes an accurate forecast of agriculture GDP possible. Using the estimated model, the future value of quarter agricultural GDP from March 2011 to July 2012was forecasted. With consideration to the fair fit of this model with agricultural GDP, It is recommended to use periodic autoregressive model for the future studies.

    Aspergillus and its poisonous mycotoxins are distributed worldwide throughout the environment and are of particular interest in agriculture and food safety. In order to develop a specific method for rapid detection of Aspergillus flavus to forecast diseases and control aflatoxins, a nanobody, PO8-VHH, highly reactive to A. flavus was isolated from an immunized alpaca nanobody library by phage display. The nanobody was verified to bind to the components of extracellular and intracellular antigen from both A. flavus and A. parasiticus. To construct a sandwich format immunoassay, polyclonal antibodies against Aspergillus were raised with rabbits. Finally, a highly selective nanobody-polyclonal antibody sandwich enzyme-linked immunosorbent assay was optimized and developed. The results revealed that the detection limits of the two fungi were as low as 1 μg mL -1 , and that it is able to detect fungal concentrations below to 2 μg mg -1 of peanut and maize grains in both artificially and naturally contaminated samples. Therefore, we here provided a rapid and simple method for monitoring Aspergillus spp. contamination in agricultural products.

    Setting up a sustainable agricultural vegetative waste-management system is a challenging investment task, particularly when markets for output products of waste-treatment technologies are not well established. We conduct an economic analysis of possible investments in treatment technologies of agricultural vegetative waste, while accounting for fluctuating output prices. Under a risk-neutral approach, we find the range of output-product prices within which each considered technology becomes most profitable, using average final prices as the exclusive factor. Under a risk-averse perspective, we rank the treatment technologies based on their computed certainty-equivalent profits as functions of the coefficient of variation of the technologies' output prices. We find the ranking of treatment technologies based on average prices to be robust to output-price fluctuations provided that the coefficient of variation of the output prices is below about 0.4, that is, approximately twice as high as that of well-established recycled-material markets such as glass, paper and plastic. We discuss some policy implications that arise from our analysis regarding vegetative waste management and its associated risks. Copyright © 2018 Elsevier Ltd. All rights reserved.

  5. Qualitative relation between heavy metal concentration in soil and agricultural products: a Chinese peri-urban case study

    A peri-urban area refers to a transition or interaction zone, where urban and rural activities are juxtaposed, and landscape features are subject to rapid modifications, mainly due to human activities. It is reported that peri-urban areas which might include valuable protected areas (e.g. forested hills, preserved woodlands, prime agricultural lands, etc.) can provide essential life support services for urban residents. A peri-urban area is not only a zone experiencing the immediate impacts of land demands from urban growth and pollution, but it is also a wider market-related zone of influence, recognized for the supply of agricultural and natural resource products. It is reported that China's environmental crisis is one of the most pressing challenges to emerge from the country's rapid industrialization; therefore a field study was carried out to investigate the qualitative relation of soil property with vegetable agricultural products in the Chinese peri-urban area located in Luoyang city (34°37'N and 112°27'E). Soil, water and plant (e.g. squash, Cucurbita maxima) samples were taken over the study site, and heavy metal concentrations were analyzed. All the soil samples showed Cd concentrations exceeded the permissible level established by Chinese guidelines for soil quality (0.3 mg/kg). The contents of Zn, Pb and Cu also surpassed the Chinese guideline levels (Zn = 250 mg/kg, Pb = 50 mg/kg and Cu = 100 mg/kg) in several soil samples. Although the sampled plants contained some degree of all the heavy metals, only the Al concentration was high in the Cucurbita maxima samples (317 mg/kg), which is a specie of cultivated squash. Considering the world market and the global trade of agricultural products, it can be said that the food risk associated with farm products containing Al is not local but global. It is concluded that an environmental contamination of the peri-urban areas may lead to the threat to food security.

  6. Agricultural productivity and greenhouse gas emissions: trade-offs or synergies between mitigation and food security?

    2013-01-01

    In this letter, we investigate the effects of crop yield and livestock feed efficiency scenarios on greenhouse gas (GHG) emissions from agriculture and land use change in developing countries. We analyze mitigation associated with different productivity pathways using the global partial equilibrium model GLOBIOM. Our results confirm that yield increase could mitigate some agriculture-related emissions growth over the next decades. Closing yield gaps by 50% for crops and 25% for livestock by 2050 would decrease agriculture and land use change emissions by 8% overall, and by 12% per calorie produced. However, the outcome is sensitive to the technological path and which factor benefits from productivity gains: sustainable land intensification would increase GHG savings by one-third when compared with a fertilizer intensive pathway. Reaching higher yield through total factor productivity gains would be more efficient on the food supply side but halve emissions savings due to a strong rebound effect on the demand side. Improvement in the crop or livestock sector would have different implications: crop yield increase would bring the largest food provision benefits, whereas livestock productivity gains would allow the greatest reductions in GHG emission. Combining productivity increases in the two sectors appears to be the most efficient way to exploit mitigation and food security co-benefits. (letter)

    development in the mid-1960s which required insertion into the world economy, notably through a search for new export sectors. The agricultural sector was assigned 3 functions: producing food as cheaply as possible, increasing the proportion of exportable crops, and substituting some of the foods imported. Brazil evolved in 2 decades from a classic agroexporter to a more complex structure reflecting the semiindustrialized state of the economy. The share of processed agricultural goods increased accordingly. The foods produced for the internal market have been changing at the same time that a new hierarchy of exportable products has evolved. Agricultural policy involved recourse to market mechanisms and cheap credit focused on the south and southeastern regions, large and medium sized producers, and a few products including soy, coffee, sugar cane, and cotton. Just 3% of credits went to the traditional foodstuffs beans and manioc. The most serious consequence of the internationalization of the agricultural economy has been a dangerous increase in the vulnerability of low income groups to world food price fluctuations.

    Full Text Available The World Agricultural Outlook Board (WAOB, under the direction of the Department of Agriculture's Office of the Chief Economist, employs a staff of agricultural meteorologists whose mission is to monitor and assess the impacts of weather and climate on crops in key growing areas throughout the world. The results of those analyses contribute to the deliberations conducted by the Interagency Commodity Estimates Committees (ICEC led by analysts at the World Agricultural Outlook Board. The results of those deliberations can be found in the World Agricultural Supply and Demand Estimates (WASDE report, one of the designated Principle Federal Economic Indicators issued monthly by the Federal Government (White House (Office of Management and Budget, 2015. The process used to develop those estimates each month requires the integration of an assessment of the current climatic conditions with knowledge of the agricultural practices and market conditions of a particular country. Weather and climate data are used in conjunction with information on when and where crops are planted, production practices including irrigation, which varieties are best suited for that particular climate, and what naturally occurring hazards can be expected in any given year. Being able to closely compare current conditions to historic observations of weather and realized output on a fine scale, temporally and geographically, is a key component of the international estimates in the WASDE process.

    2007-11-01

    The quality concern of food and agricultural products has become more and more significant. The related technologies for nondestructive measurement or quality control of food products have been the focus of many researches. Terahertz (THz) radiation, or THz wave, the least explored region of the spectrum, is the electromagnetic wave that lies between mid-infrared and microwave radiation, which has very important research and application values. THz spectroscopy and THz imaging technique are the two main applications of THz wave. During the past decade, THz waves have been used to characterize the electronic, vibrational and compositional properties of solid, liquid and gas phase materials. Recently, THz technology has gained a lot of attention of researchers in various fields from biological spectral analysis to bio-medical imaging due to its unique features compared with microwave and optical waves. In the present paper, the properties of THz wave and its uniqueness in sensing and imaging applications were discussed. The most recent researches on THz technology used in food quality control and agricultural products inspection were summarized. The prospect of this novel technology in agriculture and food industry was also discussed.

    There is a basic lack of information about the presence of pesticide residues in the environment in Central America. Over the period of February 1995 to June 1997, river, well, lagoon and spring water samples, as well as soil, fish tissue, lagoon bed sediments and some foodstuffs were taken from the greater Cholutecan River Basin of Honduras and analyzed for pesticide residues. These were collected at three separate sites (La Lima, Zamorano and Choluteca), each characterized by differing agricultural production systems. The main pesticide residues found in soil samples were dieldrin and p,p'-DDT, while river water samples were found to have detectable levels of heptachlor, endosulfan and chlorpyrifos, with lagoon and well water also being shown to contain heptachlor. These pesticides detected were in more than 20% of the samples assessed. In river water samples more pesticide residues at higher concentrations were found to be associated with areas of more intensive agricultural production. The fewest pesticides with lowest concentrations were found in the small subwatershed associated with traditional agricultural production. Although the pesticides found in the soils at the three sites were generally similar they tended to be higher in the southern part of the Cholutecan watershed, followed by the central zone, with the lowest concentrations being found in the more traditional production zone. In lagoon and well water samples more pesticides, but mostly in lower concentrations were detected at the traditional production site than at the others. Ten pesticide compounds were detected in fish tissue, mainly organochlorines, some of which were also found in lagoon sediments. In terms of food products, almost no pesticides were detected in vegetables, but the kidney adipose tissue taken from slaughtered cows was shown to have a tendency to contain some organochlorines. Spring water in the traditional agricultural production zone contained three organochlorine compounds

    1994-01-01

    Low levels of naturally occurring radionuclides exist in phosphatic clays, a by-product of phosphatic mining and beneficiation processes. Concerns about these radionuclides entering the human food chain were an immediate research priority before the phosphate clays could be reclaimed for intensive agricultural purposes. Efforts included the assembly of a large body of data from both sons and plants, part of which were produced by the Polk County (Florida) Mined Lands Agricultural Research/Demonstration Project MLAR/DP. Additional detailed studies involving dairy and beef cattle (Bos taurus) were conducted by researchers working with the MLAR/DP. A national symposium was conducted in which data concerning the MLAR/DP work and other research projects also dealing with naturally occurring radionuclides in agriculture could be discussed. The symposium included invited review papers dealing with the identification of radionuclide geological origins, the geochemistry and movement of radionuclides within the environment, mechanisms of plant uptake, entry points into the food chain, and evaluation of dose and risk assessment to the consumer of low levels of radionuclides. The risk to human health of an individual obtaining 0.1 of his or her dietary intake from crops produced on phosphatic clays increased by 1 in 5 x 10 6 /yr above a control individual consuming no food grown on phosphatic clays. Leaf tissues were found to be generally higher than fruit, grain, or root tissues. The natural range in radionuclide content among various food types was greater than the difference in radionuclides content between the same food produced on phosphatic clays vs. natural soils. 19 refs

  14. Framing the Future with Bacteriophages in Agriculture.

    Svircev, Antonet; Roach, Dwayne; Castle, Alan

    2018-04-25

    The ability of agriculture to continually provide food to a growing world population is of crucial importance. Bacterial diseases of plants and animals have continually reduced production since the advent of crop cultivation and animal husbandry practices. Antibiotics have been used extensively to mitigate these losses. The rise of antimicrobial resistant (AMR) bacteria, however, together with consumers’ calls for antibiotic-free products, presents problems that threaten sustainable agriculture. Bacteriophages (phages) are proposed as bacterial population control alternatives to antibiotics. Their unique properties make them highly promising but challenging antimicrobials. The use of phages in agriculture also presents a number of unique challenges. This mini-review summarizes recent development and perspectives of phages used as antimicrobial agents in plant and animal agriculture at the farm level. The main pathogens and their adjoining phage therapies are discussed.

  15. A technical selection of suitable agricultural products for the application of radurisation technology

    International Nuclear Information System (INIS)

    Hill, N.D.

    1989-01-01

    The commercial utilization of radurization technology has not reached the levels expected due, predominantly, to two contributing factors. Over and above the suspicions held by the consumer towards food radurization, a dearth of information exists regarding the costs of applying this technology. It appears, therefore, that if the question of consumer acceptance is surmounted, an indication of benefit costs would be crucial to convincing potential radurization users whether or not this technology can provide any economic benefit. The range of food and agricultural products consumed in South Africa is very diverse. To determine the radurization benefit cost of each food product consumed in South Africa would, therefore, be a monumental task. As a result an investigation was commissioned by the Study Group for the Techno-Economic Aspects of the Steering Committee for the Marketing of Radurized Food Products. This investigation was aimed, in the first instance, at identifying those food and agricultural products best suited for the application of this technology, thereby creating a short list on which detailed benefit cost analyses could be performed

  16. Bridging environmental and financial cost of dairy production: A case study of Irish agricultural policy.

    2018-02-15

    The Irish agricultural policy 'Food Harvest 2020' is a roadmap for sectoral expansion and Irish dairy farming is expected to intensify, which could influence the environmental and economic performance of Irish milk production. Evaluating the total environmental impacts and the real cost of Irish milk production is a key step towards understanding the possibility of sustainable production. This paper addresses two main issues: aggregation of environmental impacts of Irish milk production by monetization, to understand the real cost of Irish milk production, including the environmental costs; and the effect of the agricultural policy 'Food Harvest 2020' on total cost (combining financial cost and environmental cost) of Irish milk production. This study used 2013 Irish dairy farming as a baseline, and defined 'bottom', 'target' and 'optimum' scenarios, according to the change of elementary inputs required to meet agricultural policy ambitions. The study demonstrated that the three monetization methods, Stepwise 2006, Eco-cost 2012 and EPS 2000, could be used for aggregating different environmental impacts into monetary unit, and to provide an insight for evaluating policy related to total environmental performance. The results showed that the total environmental cost of Irish milk production could be greater than the financial cost (up to €0.53/kg energy corrected milk). The dairy expansion policy with improved herbage utilization and fertilizer application could reduce financial cost and minimize the total environmental cost of per unit milk produced.

    Meeting agricultural demand in the face of a changing climate will be one of the major challenges of the 21st century. California is the single largest agricultural producer in the United States but is prone to extreme hydrologic events, including multi-year droughts. Ventura County is one of California’s most productive growing regions but faces water shortages and deteriorating water quality. The future of California’s agriculture is dependent on our ability to identify and implement alternative irrigation water sources and technologies. Two such alternative water sources are recycled and desalinated water. The proximity of high-value crops in Ventura County to both dense population centers and the Pacific Ocean makes it a prime candidate for alternative water sources. This study uses highly localized spatial and temporal data to assess life-cycle energy use, life-cycle greenhouse gas emissions, operational costs, applied water demand, and on-farm labor requirements for four high-value crops. A complete switch from conventional irrigation with groundwater and surface water to recycled water would increase the life-cycle greenhouse gas emissions associated with strawberry, lemon, celery, and avocado production by approximately 14%, 7%, 59%, and 9%, respectively. Switching from groundwater and surface water to desalinated water would increase life-cycle greenhouse gas emissions by 33%, 210%, 140%, and 270%, respectively. The use of recycled or desalinated water for irrigation is most financially tenable for strawberries due to their relatively high value and close proximity to water treatment facilities. However, changing strawberry packaging has a greater potential impact on life-cycle energy use and greenhouse gas emissions than switching the water source. While this analysis does not consider the impact of water quality on crop yields, previous studies suggest that switching to recycled water could result in significant yield increases due to its lower

    2015-08-01

    Full Text Available This paper demonstrates how the short messaging service SMS popularly known as texting has facilitated production of solutions to farm issues using the Farmers Text Centre FTC of the Philippine Rice Research PhilRice as the case study. Text messages registered in the FTC database in 2010 covering one cropping season were discourse analyzed. Interpretive qualitative research particularly the Grounded Theory was employed to interprettheorize said data. Since texting is a new emerging discourse in agricultural development Grounded Theory allows the explication of theoretical accounts that explain its existence and impact. Results indicate that timing queries received within working days from 8am to 5pm get speedy response content the easier the question the faster it gets reply length the shorter the message the better and clarity of the querytext message as well as cultural factors such as greetings and terms of respect are all important governing factors in texting for farm use. Moreover analysis reveals that the series of text messages sent back and forth by farmers and agricultural specialist in FTC suggests a dynamic process of negotiation rather than passive information sharing. The analysis further reveals that texting has allowed farmers to have access to a negotiated knowledge rather than a standard scientific recommendation vis--vis the solution to their farm issues. The term negotiated implies that farmers are actively involved in knowledge production via texting. Textholder is coined in this paper to describe farmers and agricultural specialists as co-creators of knowledge in texting as opposed to their traditional role as knowledge generator and user respectively. From the analysis reflections implications and theoretical contributions are drawn in relation to the value of SMSing in agricultural extension and communication.

    Recently, hydrogen production from biomass has become an attractive technology for power generation. The main objective pursued in this work is to investigate the hydrogen production potential from agricultural wastes (coconut coir and palm kernel shell) by applying the air gasification technique. An experimental study was conducted using a bench-scale fluidized bed gasifier with 60 mm diameter and 425 mm height. During the experiments, the fuel properties and the effects of operating parameters such as gasification temperatures (700 to 900 {sup o}C), fluidization ratio (2 to 3.33 m/s), static bed height (10 to 30 mm) and equivalence ratio (0.16 to 0.46) were studied. It was concluded that substantial amounts of hydrogen gas (up to 67 mol%) could be produced utilizing agricultural residues such as coconut and palm kernel shell by applying this fluidization technique. For both samples, the rise of temperature till 900 {sup o}C favored further hydrocarbon reactions and allowed an increase of almost 67 mol% in the release of hydrogen. However, other parameters such as fluidising velocity and feed load showed only minor effects on hydrogen yield. In conclusion, agricultural waste can be assumed as an alternative renewable energy source to the fossil fuels, and the environmental pollution originating from the disposal of agricultural residues can be partially reduced.

    The Italian production of agricultural residues has been evaluated with a view to energy recovery through gasification. Two main categories of residues have been identified: the first, (A) is associated with the growing and collection of products with a nutritional value, whereas the second (B) includes the residues associated with the subsequent processing in order to obtain final products for commercialization. Category A, which comprises three further sub-categories: straw (A1); woody residues (A2); and stems and leaves (residues from vegetables, tobacco, sugar beet, (A3)), results in about 16.5 mt yr. The average amount of straw (A1) is 11 mt/yr, of which about 60% is waste to be eliminated. Woody residues (A2) (mainly pruning off-cuts from vineyards and olive groves) are about 3.5 mt/yr (85% unused). Category A3 amounts to about 2 mt/yr (90% unused). Straw is available mainly in the northern part of the country, whereas the other two sub-categories are widely distributed in central and southern regions. The yields of category B are estimated at 4 mt/yr, of which more than 3 mt/yr are waste products from grape and olive processing. Other residues, such as rice, sunflower and soya-bean husks (about 0.65 mt/yr), almond and nut shells and fruit stones (about 0.2 mt/yr), although not widely available on a national scale, can be significant on a local basis. The total amount of unused agricultural residues is about 14.5 mt/yr, which, if completely exploited through gasification, can contribute as much as 7-10% to the current national electricity needs. The regions of Veneto, Puglia, Friuli, Lombardia and Emilia Romagna appear to be good candidates for electricity production, given the significant surface concentration of unused residues (105-55 t km{sup 2}).

    To pre-establish an alternative technique to the toxic fumigant, methyl bromide which is the current quarantine measure of agricultural products for export and import, some selected agricultural products, such as chestnut, acorn, red bean and mung bean, were subjected to a preliminary study to confirm the comparative effects of gamma irradiation and MBr fumigant on their disinfestation and quality, thereby preparing the basic data for the practical approach. Current quarantine activities were examined and the related limitations were investigated. Quarantine-related pests were investigated on their radiosensitivity and disinfestation effects by both treatments. The pests in chestnut and acorn, Curculio skkimensis Heller, Curculio dentipes Roelofs, and Dichocrocis punctiferalis Guenee showed an increased mortality when exposed to above 0.5 kGy irradiation, resulting in 100% of mortality three weeks later. Callosobruchus chinensis Linne from both red and mung beans revealed a apparent mortality at around 10 days after irradiation of 1 to 3 kGy. Current fumigation was perfect in its disinfesting capability, but it caused the detrimental effects on physical quality of agricultural produce. Whereas, irradiation doses suitable for controlling the pests did not induce any significant changes in the quality of the samples. (author). 53 refs., 74 figs., 138 tabs.

    The objective of this investigation is identification the relation between the naturals resources degradation, and the Colombian agriculture productive. It's means a way to quantification the influence of a bad utilization in the water and land resources in the agricultural sector, to guide the sector in to a sustainable development. This objective is to make by an empirical exercise where we built four econometrics models (ordinary minims square) based in the Colombia's history statistic of the variables: land erosion, river sedimentation, plaguicides, Insecticides, Fungicides y Herbicides, agriculture productivity and agriculture yield. The resolute of this exercise is that an increase in the erosion area also the river sedimentation gives a decrease in the agriculture productivity. The same situation happens when it use the consumption of the insecticides and the fungicides which in the long time shows an opposite relation with the yield and productivity. At last we have that the aperture of the ninety's, bring to good changes for the agricultural productivity. So that, it concludes that the rivers and lands degradation affect in the long time the agriculture yield and productivity. The best use in the naturals resources, can help to increase the agricultural development, because it can increase the yield while it maintain for the future the possibility curve of production when it conserve the resources

    California agriculture is an important economic activity for the state. California leads the nation in farms sales since 1950. In addition, agricultural employment in California reached approximately 410,000. Production of many fruits and vegetables is labor intensive and labor costs represent anywhere from 20% to 40% of total production costs. In additon, agricutlural production growth has been the highest for labor intensive crops such as berries (all types) and nuts. Given the importance of the agricultural sector and the labor component whithin it, the analysis of the impact of climate change on the agricultural sector of California becomes imperative. Heat waves are a weather related extreme that impact labor productivity, specially outdoor labor producitivity. We use crop production function analysis that incorporates socio economic variables such as crop prices, total acreage, production levels and harvest timiline with climate related variables such as an estimated Heat Index (HI) to analize the impact of heat waves on crop production via an impact on labor productivity for selected crops in the Central and Imperial Valleys in California. The analysis finds that the impact of heat waves varies by the degree of labor intensity of the crop and the relative intensity of the heat wave.

    Full Text Available Argentina is among the four largest producers of soybeans, sunflower, corn, and wheat, among other agricultural products. Institutional and policy changes during the 1990s fostered the development of Argentine agriculture and the introduction of innovative process and product technologies (no-till, agrochemicals, GMO, GPS and new investments in modern, large-scale sunflower and soybean processing plants. In addition to technological changes, a "quiet revolution" occurred in the way agricultural production was carried out and organized: from self-production or ownership agriculture to a contract-based agriculture. The objective of this paper is to explore and describe the emergence of networks in the Argentine crop production sector. The paper presents and describes four cases that currently represent about 50% of total grain and oilseed production in Argentina: "informal hybrid form", "agricultural trust fund", "investor-oriented corporate structure", and "network of networks". In all cases, hybrid forms involve a group of actors linked by common objectives, mainly to gain scale, share resources, and improve the profitability of the business. Informal contracts seem to be the most common way of organizing the agriculture process, but using short-term contracts and sequential interfirm collaboration. Networks of networks involve long-term relationships and social development, and reciprocal interfirm collaboration. Agricultural trust fund and investor-oriented corporate structures have combined interfirm collaboration and medium-term relationships. These organizational forms are highly flexible and show a great capacity to adapt to challenges; they are competitive because they enjoy aligned incentives, flexibility, and adaptability.

    Full Text Available Republic of Serbia consumes about 15 million tons of equivalent oil per year (Mtoe. At the same time potential of the renewable energy sources is about 3,5 Mtoe/year. Main renewable source is biomass, with its potential of about 2,6 Mtoe/year, and 60% of the total biomass source is of agricultural origin. Mainly, that type of biomass is collected, transported and stored in form of bales. At the same time in one of the largest agricultural companies in Serbia (PKB there are over 2000 ha of soya plantations, and also 4000 t/year of baled soya straw available, none of which being used for energy purposes. Therefore, efforts have been made in the Laboratory for Thermal Engineering and Energy of the "Vinča" Institute to develop a technology for utilizing bales of various sizes and shapes for energy production. Satisfactory test results of the 1 MW experimental facility - low CO levels and stable thermal output - led to the building-up of a 1.5 MW soya straw bales-fired hot water boiler, with cigarette type of combustion, for the purposes of greenhouse and office heating in the PKB. Further more, achieving good results in exploitation of that hot water boiler, the next step is building up the first combined heat and power (electricity production facility (CHP, which will use agricultural biomass as a fuel, in Serbia.

    Water logged Tal area is termed as the stretch of land having bowl shaped depressions inundated in monsoon season due to spill/overflow from rivers or runoff from upstream end. A team of Agricultural Scientists studied and suggested a suitable plan to the Ministry of Agriculture, Government of India for improving the agricultural productivity of 40,000 hectares land lying between Ghoraghat and Bariarpur and Prasando to Khand Bihari in Munger district of Bihar, which lies in eastern India. These lands remain inundated with water from July till January. Tal lands in Bariarpur suffer due to stagnation of water during monsoon period and delay in drainage thereafter. This is a late winter mono-cropped area with very low productivity. Though the fertility status of soil is good, the quantity and quality of produce is poor. The canal network is also not efficient and other parts face drought. It is expected that the Ministry of Agriculture, Government of India will take up the action plan as per the recommendations of expert scientists' team to mitigate the sufferings and misery of the farmers and rural population of the area. The team of scientists had investigated in detail the genesis of the problem and suggested the appropriate management strategies to improve the agricultural production in this area upon the instruction of the Hon'ble Union Agricultural Minister Mr. Nitish Kumar. A reputed Journalist and dedicated Social Worker Mr. Dinesh brought the unbelievable misery of the rural population to the attention of the Agricultural Minister. The sufferings of the farmers of Bariarpur tal area thus cannot be mitigated without the implementation of recommendations suggested in the scientific report. It seems that a financial crunch is coming in the way for such implementation. Ministry of Agriculture, Ministry of Water Resources, State Government, NGOs and Social Organizations should come forward to help the rural population otherwise the ray of hope for a better living

    Full Text Available China’s urbanization has resulted in significant changes in agricultural land use. However, understanding of the linkages between urbanization and fertilizer use intensity is limited. Using county-level panel data for Henan Province, 1995–2008 and panel econometric models, we investigate the impact of urbanization and other socioeconomic factors on fertilizer use intensity, with a focus on the two key processes related to urbanization—shrinking agricultural land area and increasing urban wages. Our results show that declining agricultural land per capita is associated with greater fertilizer use intensity. Urban wages is positively correlated with fertilizer use intensity. We also find that GDP per capita and per capita expenditure of government for agriculture both positively contribute to the increase of fertilizer use intensity, which is consistent with expectations. Our results imply that other than land conversion, urbanization contains some positive influences on land use sustainability. However, on the other hand, urbanization contributes to agriculture-based environmental pollution by increasing the level of fertilizer use in agricultural production.

    2016-01-01

    Full Text Available Climate risks pose a threat to the function of the global food system and therefore also a hazard to the global financial sector, the stability of governments, and the food security and health of the world’s population. This paper presents a method to assess plausible impacts of an agricultural production shock and potential materiality for global insurers. A hypothetical, near-term, plausible, extreme scenario was developed based upon modules of historical agricultural production shocks, linked under a warm phase El Niño-Southern Oscillation (ENSO meteorological framework. The scenario included teleconnected floods and droughts in disparate agricultural production regions around the world, as well as plausible, extreme biotic shocks. In this scenario, global crop yield declines of 10% for maize, 11% for soy, 7% for wheat and 7% for rice result in quadrupled commodity prices and commodity stock fluctuations, civil unrest, significant negative humanitarian consequences and major financial losses worldwide. This work illustrates a need for the scientific community to partner across sectors and industries towards better-integrated global data, modeling and analytical capacities, to better respond to and prepare for concurrent agricultural failure. Governments, humanitarian organizations and the private sector collectively may recognize significant benefits from more systematic assessment of exposure to agricultural climate risk.

    Full Text Available Poor efficiency in the use of land, labor, finance and other resources available is characteristic of Russia’s agriculture at the present stage. In most subindustries, the country has not yet achieved the production volume of the early 90s. In the last decade there was a positive trend marked to update logistics and intensify innovative advance in the agriculture, the processes being actively supported by the state, but this did not result in appreciable improvements of the agriculture competitiveness in the global food market. During the study it is revealed that the industry credit debt has gone up three-fold over the past 7 years that made up 1.43trillion rubles versus 112 billion rubles of revenue in 2012. The authors propose a technique to attract private investments in the agriculture of Russia and economic-organizing mechanism to realize it. Hereto, a considerable part is played by state regulation, particularly to provide investment-back guarantees in the event that a project-implementing agricultural organization goes bankrupt. To hold up, the authors consider a number of investment projects implemented by one of the Russian Federation entities which demonstrate their effectiveness both for the investors and the state. Employing the data obtained from the study will allow to largely increase the rates of technical and technological re-equipment of the industry, improve its investment attractiveness and competitiveness based on innovations and this will provide the country's food safety and gross domestic product growth.

    Full Text Available The identification of commercial circuits in the Machala canton contributes to the economic and social development of the members of the San José de Guartiguro agricultural cooperative located in the Guanazón parish of Zaruma canton. The purpose of this paper was to identify commercial circuits for the marketing of baskets of organic agricultural products in nine Public Ministries of Machala. An inquiry was carried out among 138 workers, and the distribution process of the baskets was observed. The program Microsoft Excel 2013was applied to organize data in tables and graphics. Results showed that 84.14% of the workers inquired agreed to purchase the baskets at the Ministries. The implementation of commercial circuits in Machala canton that will favor the access of the members of the agricultural cooperative to institutional markets is proposed. This measure will also enable the workers at the Ministries to acquire organic agricultural products at lower prices in their work place.

    Rapid acceleration of human-water interactions have been identified in many regions of the world, often resulting in reduced water security. In the Arkavathy watershed adjacent to Bangalore, India, environmental and human systems have collectively experienced major transformations since the initiation of sustainable agriculture near the beginning of the Holocene. We reconstruct a narrative history of water security in the Arkavathy, focusing on quantitative metrics of productivity, equity, and resilience. Over this time period, the system can be separated into multiple distinct eras characterized by the dominant practices of agriculture and water management, including the unmanaged (natural) plant ecology of the region, followed by subsistence farming, tank irrigation, construction of large reservoirs, groundwater depletion, and decentralized adaptation. Each of these eras was initiated by a combination of external drivers (e.g., climate, technology) and internal drivers (e.g., demand for food and water). The last fifty years have been characterized by rapid increase in productivity largely sustained by expansion of groundwater irrigation and increasing demand from the rapidly urbanizing Bangalore. Equity initially increased with the introduction of groundwater irrigation and the increased access to irrigation supply. As the water table declined and groundwater irrigation became less affordable, resilience of the system decreased and was followed by a decrease in equity and productivity, with wealthier farmers reaping the benefits and poorer farmers unable to afford access to groundwater. Absent meaningful changes to water rights policy, the system appears to be trending towards a new, undesirable equilibrium characterized by high inequality, moderate productivity (concentrated among the wealthiest farmers), and low resilience.

    Full Text Available Following recent NSW Government restructuring, the Department of Agriculture now exists in a composite form along with Forestry, Fisheries and Minerals in the new NSW Department of Primary Industries. This paper outlines some of the highlights of secondary metabolite R&D accomplished in the 25 years since the essential oil research unit was transferred from the Museum of Applied Arts & Sciences, Sydney to NSW Agriculture’s Wollongbar Agricultural Institute on the NSW north coast. The essential oil survey was continued, typing the Australian flora as a suitable source of isolates such as myrtenal (Astartea, myrtenol (Agonis, methyl chavicol (Ochrosperma, α-phellandren-8-ol (Prostanthera, methyl myrtenate (Darwinia, methyl geranate (Darwinia, kessane (Acacia, cis-dihydroagarofuran (Prosthanthera, protoanemonin (Clematis, isoamyl isovalerate (Micromyrtus, methyl cinnamate (Eucalyptus and bornyl acetate (Boronia. Many of these components are used, or have potential use in the fragrance, flavour, medicinal plant or insect attraction fields. Two weeds toxic to livestock in the Central West of the State are also harvested commercially as medicinal plants. Measurement of hypericin concentrations in the various plant parts of St John’s Wort (Hypericum perforatum over two seasons has shown that the weed can be effectively managed by grazing sheep during the winter months when toxin levels are low. Syntheses of β-carbolines tribulusterine and perlolyrine have shown that the former alkaloid was misidentified in the literature and hence not the toxic principle responsible for Tribulus staggers in sheep. Poor quality (high 1,8-cineole – low terpinen-4-ol oil bearing tea tree (Melaleuca alternifolia plantations have been established to the detriment of many a tea tree farmer.

    This paper used the modern evaluation method of DEA (Data Envelopment Analysis) to assess the comparative efficiency and then on the basis of this among multiple schemes chose the optimal scheme of agricultural production structure adjustment. Based on the results of DEA model, we dissected scale advantages of each discretionary scheme or plan. We examined scale advantages of each discretionary scheme, tested profoundly a definitive purpose behind not-DEA efficient, which elucidated the system and methodology to enhance these discretionary plans. At the end, another method had been proposed to rank and select the optimal scheme. The research was important to guide the practice if the modification of agricultural production industrial structure was carried on.

  2. Integrating agricultural expansion into conservation biogeography: conflicts and priorities

    Ricardo Dobrovolski

    2014-06-01

    Full Text Available Increasing food production without compromising biodiversity is one of the great challenges for humanity. The aims of my thesis were to define spatial priorities for biodiversity conservation and to evaluate conservation conflicts considering agricultural expansion in the 21st century. I also tested the effect of globalizing conservation efforts on both food production and biodiversity conservation. I found spatial conflicts between biodiversity conservation and agricultural expansion. However, incorporating agricultural expansion data into the spatial prioritization process can significantly alleviate conservation conflicts, by reducing spatial correlation between the areas under high impact of agriculture and the priority areas for conservation. Moreover, developing conservation blueprints at the global scale, instead of the usual approach based on national boundaries, can benefit both food production and biodiversity. Based on these findings I conclude that the incorporation of agricultural expansion as a key component for defining global conservation strategies should be added to the list of solutions for our cultivated planet.

  3. The Assessment of Climatological Impacts on Agricultural Production and Residential Energy Demand

    Cooter, Ellen Jean

    The assessment of climatological impacts on selected economic activities is presented as a multi-step, inter -disciplinary problem. The assessment process which is addressed explicitly in this report focuses on (1) user identification, (2) direct impact model selection, (3) methodological development, (4) product development and (5) product communication. Two user groups of major economic importance were selected for study; agriculture and gas utilities. The broad agricultural sector is further defined as U.S.A. corn production. The general category of utilities is narrowed to Oklahoma residential gas heating demand. The CERES physiological growth model was selected as the process model for corn production. The statistical analysis for corn production suggests that (1) although this is a statistically complex model, it can yield useful impact information, (2) as a result of output distributional biases, traditional statistical techniques are not adequate analytical tools, (3) the model yield distribution as a whole is probably non-Gausian, particularly in the tails and (4) there appears to be identifiable weekly patterns of forecasted yields throughout the growing season. Agricultural quantities developed include point yield impact estimates and distributional characteristics, geographic corn weather distributions, return period estimates, decision making criteria (confidence limits) and time series of indices. These products were communicated in economic terms through the use of a Bayesian decision example and an econometric model. The NBSLD energy load model was selected to represent residential gas heating consumption. A cursory statistical analysis suggests relationships among weather variables across the Oklahoma study sites. No linear trend in "technology -free" modeled energy demand or input weather variables which would correspond to that contained in observed state -level residential energy use was detected. It is suggested that this trend is largely the

    The Belt and Road is an initiative of cooperation and development that was proposed by China. Moreover, most of the spanning countries faced water shortages and agriculture consumed a lot of water. Virtual water links water, food and trade and is an effective tool to ease water shortages. Therefore, this paper aims to understand the Belt and Road from the new perspective of virtual water trade of agricultural products. We considered agricultural products trade from 2001 to 2015. On the whole, the results indicated that China was in virtual water trade surplus with the countries along the Belt and Road. However, in terms of each country, >40 spanning countries were in virtual water trade surplus with China and eased water shortages. Russia had the largest net imported virtual water from China. Furthermore, the proportion of the grey water footprint that China exported to the spanning countries was much higher than that imported, no matter from the whole or different geographical regions. Moreover, more than half of the countries' virtual water trade with China conformed to the virtual water strategy, which helped to ease water crises. Furthermore, the products that they exported to China were mainly advantageous products that each spanning countries have. Virtual water trade is a new perspective to explore the Belt and Road. Agricultural products trade with China definitely benefits both the countries along the Belt and Road and China from the perspective of virtual water. The findings are beneficial for the water management of the countries along the Belt and Road and China, alleviating water shortages, encouraging the rational allocation of water resources in the various departments. They can provide references for optimizing trade structures as well. Copyright © 2017 Elsevier B.V. All rights reserved.

    Thaxtomins are virulence factors of most plant pathogenic Streptomyces strains. Due to their potent herbicidal activity, attractive environmental compatibility and inherent biodegradability, thaxtomins are key active ingredients of bioherbicides approved by the United States Environmental Protection Agency. However, the low yield of thaxtomins in native Streptomyces producers limits their wide agricultural applications. Here, we describe the high-yield production of thaxtomins in a heterologous host. The thaxtomin gene cluster from S. scabiei 87.22 was cloned and expressed in S. albus J1074 after chromosomal integration. The production of thaxtomins and nitro-tryptophan analogs were observed using LC-MS analysis. When culturing the engineered S. albus J1074 in the minimal medium TMDc, the yield of the most abundant and herbicidal analog, thaxtomin A, was 10 times higher than S. scabiei 87.22, and optimization of the medium resulted in the highest yield of thaxtomin analogs at about 222 mg/L. Further engineering of the thaxtomin biosynthetic gene cluster through gene deletion led to the production of multiple biosynthetic intermediates important to the chemical synthesis of new analogs. Additionally, the versatility of the thaxtomin biosynthetic system in S. albus J1074 was capitalized to produce one unnatural fluorinated analog 5-F-thaxtomin A, whose structure was elucidated by a combination of MS and 1D and 2D NMR analyses. Natural and unnatural thaxtomins demonstrated potent herbicidal activity in radish seedling assays. These results indicated that S. albus J1074 has the potential to produce thaxtomins and thereof with high yield, fostering their agricultural applications. IMPORTANCE Thaxtomins are agriculturally valuable herbicidal natural products but the productivity of native producers is limiting.

    Full Text Available The main aim of the paper is to analyse the impact of the EU accession on the New Member States’ agriculture with special regard to production, employment, farmers’ income and intra-EU trade in agricultural goods on the basis of the latest statistical data of Eurostat. According to our findings, accession has provided incentives to agricultural production and to utilize natural endowments (mainly agricultural land; however, agricultural employment decrease could not be halted. Nevertheless, the economic situation of the farmers improved due to increasing incomes. Though the enlarged EU provided markets for the NMS agricultural products, the competition on their domestic markets increased significantly, resulting in massive import penetration. Consequently, most of the NMS agricultural trade balance deteriorated considerably. Concerning future prospects, it highly depends on the reformulation of the Common Agricultural Policy, the new budget of the EU and the domestic economic and agricultural situation of the NMS.

  7. Iron: the forgotten driver of nitrous oxide production in agricultural soil.

    Directory of Open Access Journals (Sweden)

    Xia Zhu

    Full Text Available In response to rising interest over the years, many experiments and several models have been devised to understand emission of nitrous oxide (N2O from agricultural soils. Notably absent from almost all of this discussion is iron, even though its role in both chemical and biochemical reactions that generate N2O was recognized well before research on N2O emission began to accelerate. We revisited iron by exploring its importance alongside other soil properties commonly believed to control N2O production in agricultural systems. A set of soils from California's main agricultural regions was used to observe N2O emission under conditions representative of typical field scenarios. Results of multivariate analysis showed that in five of the twelve different conditions studied, iron ranked higher than any other intrinsic soil property in explaining observed emissions across soils. Upcoming studies stand to gain valuable information by considering iron among the drivers of N2O emission, expanding the current framework to include coupling between biotic and abiotic reactions.

    Zimbabwe’s poor are predominantly located in the semi-arid regions and rely on rainfed agriculture for their subsistence. Decline in productivity, scarcity of arable land, irrigation expansion limitations, erratic rainfall and frequent dry spells, among others cause food scarcity. The challenge faced by small-scale farmers is to enhance water productivity of rainfed agriculture by mitigating intra-seasonal dry spells (ISDS) through the adoption of new technologies such as rainwater harvesting (RWH). The paper analyses the agro-hydrological functions of RWH and assesses its impacts (at field scale) on the crop yield gap as well as the Transpirational Water Productivity ( WPT). The survey in six districts of the semi-arid Zimbabwe suggests that three parameters (water source, primary use and storage capacity) can help differentiate storage-type-RWH systems from “conventional dams”. The Agricultural Production Simulator Model (APSIM) was used to simulate seven different treatments (Control, RWH, Manure, Manure + RWH, Inorganic Nitrogen and Inorganic Nitrogen + RWH) for 30 years on alfisol deep sand, assuming no fertiliser carry over effect from season to season. The combined use of inorganic fertiliser and RWH is the only treatment that closes the yield gap. Supplemental irrigation alone not only reduces the risks of complete crop failure (from 20% down to 7% on average) for all the treatments but also enhances WPT (from 1.75 kg m -3 up to 2.3 kg m -3 on average) by mitigating ISDS.

    Terrestrial food-chain models that simulate the transport of environmentally released radionuclides incorporate parameters describing agricultural production and practice. Often a single set of default parameters, such as that listed in USNRC Regulatory Guide 1.109, is used in lieu of site-specific information. However, the geographical diversity of agricultural practice in the United States suggests the limitations of a single set of default parameters for assessment models. This report documents default parameters with a county-wide resolution based on analysis of the 1974 US Census of Agriculture for use in terrestrial food chain models. Data reported by county, together with state-based information from the US Department of Agriculture, Economic and Statistics Service, provided the basis for estimates of model input parameters. This report also describes these data bases, their limitations, and lists default parameters by county. Vegetable production is described for four categories: leafy vegetables; vegetables and fruits exposed to airborne material; vegetables, fruits, and nuts protected from airborne materials; and grains. Livestock feeds were analyzed in categories of hay, silage, pasture, and grains. Pasture consumption was estimated from cattle and sheep inventories, their feed requirements, and reported quantities of harvested forage. The results were compared with assumed yields of the pasture areas reported. In addition, non-vegetable food production estimates including milk, beef, pork, lamb, poultry, eggs, goat milk, and honey are described. The agricultural parameters and land use information - in all 47 items - are tabulated in four appendices for each of the 3067 counties of the US reported to the Census of Agriculture, excluding those in Hawaii and Alaska.

    A sensitive and reliable method for the simultaneous determination of hydroxycoumarin-type (brodifacoum, bromadiolone, coumatetralyl, and warfarin) and indandione-type (chlorophacinone, diphacinone, and pindone) rodenticides in agricultural products by gel permeation chromatography (GPC) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) was developed. The procedure involved extraction of the rodenticides from samples with acetone, followed by liquid-liquid partitioning with hexane/ethyl acetate (1:1, v/v) and 10% sodium chloride aqueous solution, then cleanup using GPC, and finally, analysis using LC-MS/MS. High recoveries from the GPC column were obtained for all rodenticides tested using a mobile phase of acetone/cyclohexane/triethylamine (400:1600:1, v/v/v). An ODS column, which contains low levels of metal impurities, gave satisfactory peak shapes for both hydroxycoumarin- and indandione-type rodenticides in the LC-MS/MS separation. The average recoveries of rodenticides from eight agricultural foods (apple, eggplant, cabbage, orange, potato, tomato, brown rice, and soybean) fortified at 0.0005-0.001 mg/kg ranged from 76 to 116%, except for bromadiolone in orange (53%) and diphacinone in soybean (54%), and the relative standard deviations ranged from 1 to 16%. The proposed method effectively removed interfering components, such as pigments and lipids, and showed high selectivity. In addition, the matrix effects were negligible for most of the rodenticide/food combinations. The results suggest that the proposed method is reliable and suitable for determining hydroxycoumarin- and indandione-type rodenticides in agricultural products.

    Photosynthetically derived biomass and residues, including waste products from food processing industries are renewable. They accumulate every year in large quantities, causing deterioration to the environment and loss of potentially valuable resources. The conserved energy is potentially convertible; thermodynamically the energy can be tapped into forms which are more amenable for value added agricultural applications or for other higher value products such as chemicals or their feedstocks. The forms and types in which this biomass has to be modified for the intended use depend on the costs or the respective alternatives. Under current situations, where chemical feedstocks are available in abundance at very competitive prices, biomass is obviously more suitably placed in the agro-industrial sector. Recycling of the biomass or residues into the soil as biofertilizers or for some other uses for agricultural applications requires less intense energy inputs for their improvements. Highly efficient biological processes with microorganisms as the primary movers in the production of the desired end products indeed require less capital costs than in most other industrial entities. In this paper, the various processes, which are potentially valuable and economically feasible in the conversion of biomass and residues for several products important in the agricultural sector, are described. Emphasis is given to the approach and the possible permutations of these processes to arrive at the desired good quality products for sustainable agricultural development. (Author)

    Full Text Available Mathematical models of inventory-distribution routing problem for two-echelon agriculture products distribution network are established, which are based on two management modes, franchise chain and regular chain, one-to-many, interval periodic order, demand depending on inventory, deteriorating treatment cost of agriculture products, start-up costs of vehicles and so forth. Then, a heuristic adaptive genetic algorithm is presented for the model of franchise chain. For the regular chain model, a two-layer genetic algorithm based on oddment modification is proposed, in which the upper layer is to determine the distribution period and quantity and the lower layer is to seek the optimal order cycle, quantity, distribution routes, and the rational oddment modification number for the distributor. By simulation experiments, the validity of the algorithms is demonstrated, and the two management modes are compared.

    Full Text Available The key objective of agricultural protectionism is reflected in the protection and developing of agriculture sector. Integrated parts of this policy in the European Union are the initial model of agricultural protectionism and a new strategy of agricultural policy, which emerged as a response to the shortcomings of previously existing model. The paper presents the key reforms of agricultural policy, conditioned to internal problems and pressures in the negotiations of trade liberalization of agricultural and food products. Reform solutions for the period of 2014 to the 2020 will have similar goals. The priority will be to develop sustainable food production and sustainable management of natural resources. There is a widespread awareness of sustainable development that includes not only the economic component (which is reflected in the increase in productivity and production efficiency, but also an environmental component (the need to preserve the environment, as well as the social component of sustainable development (integrated rural development. Conducting negotiations in the framework of liberalization of agricultural and food products, there was a gradual reduction of restrictive measures in the field of domestic agriculture protection. However, the European food market is still highly protected from foreign competition because of the many features of the agricultural production sector and the importance of agriculture for the entire society. It is certain that the CAP will lose its narrow agricultural character.

    Full Text Available The majority of farm households in Turkey and especially the Eastern Anatolia are still based on low-input semi subsistence agriculture and livestock production. Despite a slow decline in recent years, agriculture and livestock production remains a major employer in Turkey and it is a significant contributor to the country’s gross domestic product, GDP. Whist Turkey is one of the EU candidate countries, is self sufficient in food production and Turkish agriculture is poorly structured inefficient, with farming in the Eastern Anatolia being mainly subsistence farming. Yet, these traditional rural structures combined with poor access to low level of education and low level of off-farm unemployment problem makes the situation more complicated and unsustainable. The best way to promote sustainability, better and higher production of Eastern Anatolian and rural Turkey is to invest in the local people, villages through improved, continuing and effective agricultural and livestock programs in particular. Investment in human capital especially in the rural areas leads to more employment opportunities through entrepreneurship and innovation in organic agriculture and livestock production. A holistic approach to developing and improving supply chains could unlock the potential for sophisticated, state-of-the-art organic agriculture and livestock producers and businesses in the region to become EU and global players. Eastern Anatolian livestock producers and the farmers have the ambitions to take part in future progress because the region is naturally organic not by design but default. It is for sure that present potential of the region has not been fully determined and utilized. EU has greatly benefited from previous enlargements economically, politically and socially. When European Union (EU and Turkish Government relations considered and accession of Turkey to EU would be the logical consequence of the previous accessions. The screening on chapter 11

    The current study locates and quantifies abandoned agricultural areas using the Geographic Information System (GIS) and evaluates the suitability of abandoned fields for bio-energy production in Tartumaa (Tartu County) in Estonia. Soils of abandoned areas are generally of low quality and thereby limited suitability for crop production; as a result soil-crop suitability analyses could form the basis of knowledge-based bio-energy planning. The study estimated suitable areas for bio-energy production using willow (Salix sp), grey alder [Alnus incana (L.) Moench], hybrid aspen (Populus tremuloides Michx.Populus tremula L.), reed canary grass (Phalaris arundinacea L.), and Caucasian goat's rue (Galega orientalis Lam.) in separate plantations. A combined land-use strategy is also presented as these crops are partially suitable to the same areas. Reed canary grass and grey alder have the highest energy potentials and each would re-use more than 80% of the available abandoned agricultural land. Energy grasses and short-rotation forestry in combined land-use strategy represents the opportunity of covering approximately a quarter of county's annual energy demand. The study estimates only agronomic potential, so further bio-energy analysis should take into account technical and economic limitations. Developed framework supports knowledge-based decision-making processes from field to regional scale to achieve sustainable bio-energy production
