    OpenAIRE

    Arnade, Carlos Anthony

    1992-01-01

    Brazil's agricultural sector underwent major changes in the past two decades. Though Brazil is abundant in labor, land, and animal power, government subsidies encouraged the use of fertilizer and machines. Since productivity growth arises from technical change, Brazil's drive to modernize its agricultural sector should improve agricultural productivity. However, inefficient production practices arising from subsidies can slow multifactor productivity growth. Recent removal of agricultural sub...

    Piesse, J; Thirtle, C

    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. PMID:20713401

    Michele Pisante

    2012-10-01

    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.

  13. Renewable energy: Energy from agricultural products

    Science.gov (United States)

    1984-06-01

    Agricultural products, particularly sugarcane and corn, are currently meeting major energy needs in Florida. Recent figures indicate that about 10 percent of the gasoline sold in Florida is ethanol enriched. This gasohol contains a 10 percent mix of ethanol, which is generally produced from corn or sugarcane molasses. Sugarcane residues (bagasse) also supply most of the fuel to power Florida's large sugar processing industry. These products have the potential to play an expanded role in Florida's energy future. Neither ethanol nor methane appear able to compete in the free market for mass distribution at present, although studies indicate that genetic engineering and more efficient conversion processes may lower prices to cost effective levels. These fuels will be most cost effective in cases where waste products are utilized and the fuel is used close to the site of production. Wider applications will require either government incentives or genetic engineering of crops and improve efficiencies in conversion processes to lower costs.

  20. Radioactive Contamination of Agricultural Products in Poland

    International Nuclear Information System (INIS)

    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 134Cs concentration has been below the detection limit. The activity of 137Cs has been measured to determine long-term effect of the accident on the contamination of milk, meat and other foodstuffs. (orig.)

  1. Agricultural Productivity Forecasts for Improved Drought Monitoring

    Science.gov (United States)

    Limaye, Ashutosh; McNider, Richard; Moss, Donald; Alhamdan, Mohammad

    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

    A variety of carbohydrate sources can be used as raw material for the production of ethanol. Section 1 is a review of technologies available for the production of ethanol from whole corn. Particular emphasis is placed on the environmental aspects of the process, including land utilization and possible air and water pollutants. Suggestions are made for technological changes intended to improve the economics of the process as well as to reduce some of the pollution from by-product disposal. Ethanol may be derived from renewable cellulosic substances by either enzymatic or acid hydrolysis of cellulose to sugar, followed by conventional fermentation and distillation. Section 2 is a review of the use of two agricultural residues - corn stover (field stalks remaining after harvest) and straw from wheat crops - as a cellulosic feedstock. Two processes have been evaluated with regard to environmental impact - a two-stage acid process developed by G.T. Tsao of Purdue University and an enzymatic process based on the laboratory findings of C.R. Wilke of the University of California, Berkeley. Section 3 deals with the environmental residuals expected from the manufacture of methyl and ethyl alcohols from woody biomass. The methanol is produced in a gasification process, whereas ethanol is produced by hydrolysis and fermentation processes similar to those used to derive ethanol from cellulosic materials.

  16. Impact of greenhouse gases on agricultural productivity in Pakistan

    International Nuclear Information System (INIS)

    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)

    International Nuclear Information System (INIS)

    The report entitled Climate Change Impacts and Adaptation : A Canadian Perspective, presents a summary of research regarding the impacts of climate change on key sectors over the past five years as it relates to Canada. This chapter on agriculture describes how climate change will affect primary agriculture production in Canada with particular focus on potential adaptation options, and vulnerability of agriculture at the farm level. Agriculture is a vital part of the Canadian economy, although only 7 per cent of Canada's land mass is used for agricultural purposes due to the limitations of climate and soils. Most parts of Canada are expected to experience warmer conditions, longer frost-free seasons and increased evapotranspiration. The impacts of these changes on agriculture will vary depending on precipitation changes, soil conditions, and land use. Northern regions may benefit from longer farming seasons, but poor soil conditions will limit the northward expansion of agricultural crops. Some of the negative impacts associated with climate change on agriculture include increased droughts, changes in pest and pathogen outbreaks, and moisture stress. In general, it is expected that the positive and negative impacts of climate change would offset each other. 74 refs., 2 tabs., 1 fig

    Full Text Available Romania has a significant agricultural potential and agriculture in our country has an important share among sectors of the national economy. However, even if the Romanian labor productivity in agriculture had a positive development in the period 2007-2014, the level is lower than that achieved in the agricultural performance in the European Union. In order to improve labor productivity in Romanian agriculture, it is necessary to take a series of measures in order to reduce the disparities in this sector compared with the performance level from EU. For increasing the Romanian labor efficiency in agriculture, it is necessary to encourage investment and to improve the level of technology in mechanization; for the physical work done by Romanian farmer, to adjust with the performance benefits of using mechanization.

    The present investigation deals with alternative utilization processes to convert low rank coal and agricultural by products into solid, liquid and gaseous products for a more efficient exploitation of these materials. Low rank coals and different agricultural by-products were subjected to different thermochemical treatments. The composition and physico-chemical properties of liquid products obtained from agricultural by-products were investigated. The identified compounds are predominantly oxygen derivatives of phenol, dihydroxybenzenes, guaiacol, syringol, vanilin, veratrol, furan and acids. Liquids from low rank coals contain higher quality of aromatic compounds predominantly mono- and bicyclic. The amount of oxygen containing structures is high as well. By thermo-chemical treatment of liquid products from agricultural by-products, low rank coals and their mixtures with H{sub 2}SO{sub 4} carbon adsorbents with very low ash and sulfur content are obtained. Using different activation reagents large scale carbon adsorbents are prepared from agricultural by-products and coals. The results of the investigations open-up possibilities for utilization of low rank coals and agricultural by-products. 18 refs., 5 figs., 7 tabs.

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

    Science.gov (United States)

    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. PMID:20643935

  15. The Origins of Agriculture Production in the Area of Croatia

    Directory of Open Access Journals (Sweden)

    2002-12-01

    Full Text Available Food production, that is to say agricultural production begins independently in three different geographical areas: the Near East, the Far East and Central America. From the Near East agriculture spread to the entire Europe. Locations of domestication and spreading routes of Triticum dicoccum, Triticum monococcum, sheep and cattle enable us to establish directions of the spread of agriculture. Growing precision of 14C method by which date of biological material is determined makes it possible to determine the beginnings of agricultural production in specific areas and the rapidity of its spreading. Food production created the conditions for significant population growth and rapid social development. Discovery of human genome and development of a new interdisciplinary science of arhaeogenetics led to knowledge about dates of appearance of certain human haplotypes, from which the spread of agriculture by demographic diffusion or by acquiring food production know-how can be inferred. In the period between 7000 and 5000 BC developing pottery cultures were spreading simultaneously with agriculture. For the understanding of spread of agriculture to Croatia and its further advance, archaeological data on the Impresso, Starèevo, Korenovo (as a part of Linear Pottery complex, Danilo and Lengyel - Sopot cultures are of great importance.

  9. The social organization of agricultural biogas production and use

    International Nuclear Information System (INIS)

    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

    China is still largely rural, with abundant biomass resources including agricultural residues, and animal wastes amounting to about 2.5 billion tons per annum. The first National Strategy for Renewable Rural Biomass Energy Development has developed a strategy which will provide a framework for a sustainable utilization of these resources as well as develop additional resources for renewable energy reduction. To comply with these regulations, under current economic and regulatory conditions, the least-cost response for mist agro-enterprises will be the installation of conventional, ''end of pipe'' waste treatment facilities. The results of an International Seminar on Biogas for Poverty and Sustainable Development in Beijing (Peoples Republic of China) in October 2005 came up with the following strategies for large scale biogas plant implementation: (a) Integration of biogas electricity generation in national feed-in-grid strategies and village electrification; (b) Create models for biogas grids; (c) Testing clear rules for Renewable Energy laws application; (d) Promotion of large scale industrial and community plants; (e) Integration of bio-organic waste and septic/faecal sludge collection system.

    The excessive application of fertilizer and pesticides in grain production in China has posed a threat to the environrnental sustainability of agricultural production. One of the major reasons of the increasing usage of chemical inputs by farmers is their trying to reach higher yields, especially in absence of adequate public inputs, such as development and extension of appropriate technology and necessary production infrastructure, etc. Based on the cropspecific data of the past 20 years, this paper examines how the public investments in agricultural researches could impact on the reduction of farmers' private material inputs of major grain crops in China. It manifests that the increased investments in public sector, especially in agricultural researches, is a favorable and effective way to reduce farmers' private material inputs and should be given a priority consideration in the policy emendation to increase yields and improve production sustainability.

    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.

    Strategies and best practices for the co-existence of GM and non-GM crops need to be developed and implemented with the participation of farmers and other stakeholders. According to the principle of 'subsidiarity', decisions should be made by the lowest authority possible. When applying this concept to the case of GM crops, the affected society should determine their use and management in a regional decision-making process. Public participation is better accomplished at a lower level, and democratic deficits in decision-making on GMOs are better resolved, enabling farmers to manage or avoid GM crops. Ultimately, voluntary GMO-free zones might be a tool for sustainable co-existence and GM-free production and GMO-free zones might create a specific image for marketing regional products and services, such as tourism.

    2015-01-01

    An analytical method for the determination of butroxydim in agricultural products by LC-MS was developed. Butroxydim was extracted with acetonitrile and an aliquot of the crude extract was cleaned up on an octadecyl silanized silica gel (C18) cartridge column (1,000 mg), followed by a salting-out step to remove water. Before purification on a silica gel (SI) cartridge column (690 mg), polar matrices were precipitated by adding ethyl acetate, n-hexane and anhydrous sodium sulfate successively. This process effectively removed caffeine and catechins and improved recovery when analyzing residual butroxydim in tea leaves. Recovery and repeatability were good; the relative standard deviations were less than 5% for all 12 tested agricultural products (brown rice, soybean, potato, spinach, cabbage, apple, orange, grapefruit, lemon, tomato, peas with pods, and tea). Average recoveries for 11 agricultural products, except for lemon, were 74-92%. PMID:26699270

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 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.

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

    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.

    Full Text Available Fundamental concept of statistical process control is based on decision-making about the process on the basis of comparison of data collected from process with calculated control limits. Statistical process and quality control of agricultural products is used to provide agricultural products that will satisfy customer requirements in a view of quality pretension as well as costumer requirements in a cost price. In accordance with ISO 9000, quality standards for process and products are defined. There are many institutions in Croatia that work in accordance with these standards. Implementation of statistical process control and usage of a control charts can greatly help in convergence to the standards and in decreasing of production costs. To illustrate the above mentioned we tested a work quality of a nozzle at the eighteen meter clutch sprayer.

    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

    Many nations save domestic water resources by importing water-intensive products and exporting commodities that are less water intensive. National water saving through the import of a product can imply saving water at a global level if the flow is from sites with high to sites with low water productivity. The paper analyses the consequences of international virtual water flows on the global and national water budgets. The assessment shows that the total amount of water that would have been required in the importing countries if all imported agricultural products would have been produced domestically is 1605 Gm3/yr. These products are however being produced with only 1253 Gm3/yr in the exporting countries, saving global water resources by 352 Gm3/yr. This saving is 28 per cent of the international virtual water flows related to the trade of agricultural products and 6 per cent of the global water use in agriculture. National policy makers are however not interested in global water savings but in the status of national water resources. Egypt imports wheat and in doing so saves 3.6 Gm3/yr of its national water resources. Water use for producing export commodities can be beneficial, as for instance in Cote d'Ivoire, Ghana and Brazil, where the use of green water resources (mainly through rain-fed agriculture) for the production of stimulant crops for export has a positive economic impact on the national economy. However, export of 28 Gm3/yr of national water from Thailand related to rice export is at the cost of additional pressure on its blue water resources. Importing a product which has a relatively high ratio of green to blue virtual water content saves global blue water resources that generally have a higher opportunity cost than green water.

  9. Biomass energy production in agriculture: A weighted goal programming analysis

    International Nuclear Information System (INIS)

    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.

  11. The forecast of agricultural crop production contamination by Cs 137

    International Nuclear Information System (INIS)

    The saved up experimental data on the influence of various factors on radionuclides transition in plants allows predicting their contents in production of agricultural crops. It is established, that receipt radionuclides in plants depends on a kind and a grade of cultivated cultures, types of ground, granulometric structure, parameters of soil fertility, humidifying grounds, levels of application of mineral fertilizers and other factors. The determining factor on Cs 137 receipt in plants is presented in ground exchange potassium. The forecast of Cs 137 transition from ground in plants is widely used in an agricultural production at planning and realization of a complex of protective actions. According to predicted levels of Cs 137 accumulation in production the directions of its use are determined. (authors)

The method used builds on recent production function’s estimation techniques developed for panel data (e.g., Gandhi et al., 2013 but using cross-section data. Data constraints urge us to impose functional forms for the estimation. In particular, we choose the constant elasticity of substitution function, which is more flexible that other functions used by prior literature in Peru (such as the Cobb-Douglas. We find no evidence of the existence of increasing returns to scale in the Peruvian agriculture, and that the productivity is positively correlated with age, sex, andeducation, and negatively correlated with the farming unit’s acreage and market power.

    International Nuclear Information System (INIS)

    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.

  15. Implications of climate mitigation for future agricultural production

    International Nuclear Information System (INIS)

    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 ∼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 food insecure

    2009-12-01

    Agriculture is the main consumer of freshwater, and improved precision and accuracy of the terrestrial water cycle requires a more reliable way of monitoring agricultural water use and agricultural water productivity. Wisser et al 2008 reported that agricultural water consumption over the satellite-determined crop acreage (from AVHRR, SPOT VGT), particularly for India and China (Thenkabail et al 2006) was 30% higher than the commonly used Food and Agricultural Organization country-reported agricultural crop census data. We propose further quantification and clarification of this error through the following methodology: 1) greater accuracy in measuring actual area and precise spatial distribution of irrigated and rainfed cropland areas, along with identification of crop types and cropping intensities; 2) satellite monitoring of actual evapotranspiration (water use) by croplands; 3) reconciling agricultural plot information and evapotranspiration against calculated stores of water and water budgets, as derived from a Global Hydrologic Model Multi-Model Ensemble; and (d) modeling and pin-pointing areas of low and high water productivity (WP) to optimize agricultural water use and thus save large quanta of water. We propose producing global irrigated and rainfed areas at finer scales using Landsat 30 m imagery in fusion with MODIS 250 m imagery using the spectral matching technique (Thenkabail et al 2009). Crop water use (water transpired by the crop) and crop water productivity maps can be prepared for terrestrial areas, by using the surface energy balance model, in which evapotranspiration fraction is provided from Landsat ETM+ and\\or MODIS thermal data, combined with locally derived meteorological data such as wind speed, humidity, incoming radiation, and other surface values to derive turbulent diffusion and finally computing reference evapotranspiration (e.g., Penman-Montieth approach), so that sensible heat flux may be deducted from net radiation to derive

    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

For this reason we analyzed the data on land use in organic production and the volume of the market for organic products in Europe and Russia. The motivation of farmers and the driving factors for the transition to organic farming methods in developed countries and the role of subsidies have been shown. The analysis of the state of organic production in Germany has been carried out. In 2013, Germany reported 23484 organic farms, which represent 8.2% of agricultural production and the total cultivated area 1,045 Mio. ha. In organic production are involved 9 national associations with their own logos, integrated by 12250 farms (52.2%, and the remaining 11 234 biofarms (47.8% use the EU-bio logo. Over the past years there has been observed a significant increase in organic livestock production; e.g. during 2007-2012 milk, poultry meat and eggs production were increased by 58.3, 60,6 and 108.7% respectively. Price of bio eggs in November 2014 was 55.6% higher than in free-range system and 100% higher than in floor housing system. Obviously, organic production is an efficient production system capable of ensuring the economic well-being of rural areas. For further expansion of this sector in Russia is necessary to develop the economic incentives, which encourage conversion from conventional, farming to organic production. Also, it is necessary to raise awareness of producers and consumers about the quality of organic products

  3. The Supply and Demand of Agricultural Products in China Based on Balanced Diet

    Institute of Scientific and Technical Information of China (English)

    2012-01-01

    Promoting agricultural production and ensuring the supply of agricultural products has always been the main task of agricultural development in China,but the agricultural production in China has not yet been combined with the Chinese residents’ dietary needs to formulate reasonable development goals,with a certain blindness in production. According to the dietary standards in The Dietary Guidelines for Chinese Residents developed by the Chinese Nutrition Society,we calculate the demand of various types of agricultural products in China under the conditions of balanced diet. In comparison with the output of various types of agricultural products in China at present,we find that the output of most of agricultural products in China has exceeded the reasonable demand of the Chinese residents under the conditions of balanced diet. Therefore,adjusting the agricultural production structure in China and advocating balanced diet has become an important way to solve the problem of balance between supply and demand of agricultural products.

    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.

    The degradation of the natural environment and the energy crisis are two vital issues for sustainable development worldwide. Hydrogen is considered as one of the most promising candidates as a substitute for fossil fuels. In this context, biological processes are considered as the most environmentally friendly alternatives for satisfying future hydrogen demands. In particular, biohydrogen production from agricultural waste is very advantageous since agri-wastes are abundant, cheap, renewable and highly biodegradable. Considering that such wastes are complex substrates and can be degraded biologically by complex microbial ecosystems, the present paper focuses on dark fermentation as a key technology for producing hydrogen from crop residues, livestock waste and food waste. In this review, recent findings on biohydrogen production from agricultural wastes by dark fermentation are reported. Key operational parameters such as pH, partial pressure, temperature and microbial actors are discussed to facilitate further research in this domain. (author)

    Growing alarm about negative cascading effects of reactive nitrogen in the environment has led to multifaceted efforts to address elevated nitrate-nitrogen levels in water bodies worldwide. The best way to mitigate N-related impacts, such as hypoxic zones and human health concerns, is to convert nitrate to stable, non-reactive dinitrogen gas through the natural process of denitrification. This means denitrification technologies need to be one of our major strategies for tackling the grand challenge of managing human-induced changes to our global nitrogen cycle. While denitrification technologies have historically been focused on wastewater treatment, there is great interest in new lower-tech options for treating effluent and drainage water from one of our largest reactive nitrogen emitters -- agriculture. Denitrification 'woodchip' bioreactors are able to enhance this natural N-conversion via addition of a solid carbon source (e.g., woodchips) and through designs that facilitate development of anoxic conditions required for denitrification. Wood-based denitrification technologies such as woodchip bioreactors and 'sawdust' walls for groundwater have been shown to be effective at reducing nitrate loads in agricultural settings around the world. Designing these systems to be low-maintenance and to avoid removing land from agricultural production has been a primary focus of this "farmer-friendly" technology. This presentation provides a background on woodchip bioreactors including design considerations, N-removal performance, and current research worldwide. Woodchip bioreactors for the agricultural sector are an accessible new option to address society's interest in improving water quality while simultaneously allowing highly productive agricultural systems to continue to provide food in the face of increasing demand, changing global diets, and fluctuating weather.

    Degrees clearly oriented to rural and agricultural engineering are distinguished from the rest of the engineering areas by the need to involve the biological phenomena of engineering calculations. These degrees, which include subjects such as crop production, biotechnology and physics, among others, have evolved tremendously over the last ten years, implanting new curricula and introducing new specialties such as those dedicated to the environment or rural development, thereby adapting new social, economic and environmental aspects of each country. Currently being finalized to implement new titles in most Spanish universities, and in rest of Europe, following the guidelines set by Bologna. The process of elaboration of these degrees is complicated precisely because of the great variety of areas and subjects involved in these degrees. In this paper we study, for several countries of the European Union, the core subjects of the university degrees of agricultural engineering and the correlations between the core contents and the importance of the related uses of the soil in the different sectors of crop production (arable crops, horticulture, fruit growing, gardening, etc.) as well as other socio-economic criteria. The objective is to detect if the design of the core content is consistent in each country with the importance of the related socio-economic sector. Key-words: curriculum, crop production, agricultural engineer.

  17. Increasing rice production in Malaysia: Department of Agriculture approach

    International Nuclear Information System (INIS)

    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)

    Full Text Available First stage for attaining sustainability in a system is the measurement of current state of sustainability. Indicators are widely used as tools for measurement of sustainability. In this study, a comprehensive index was proposed to measure sustainability in agricultural production systems. This index takes advantage of fuzzy logic to combine all six indexes which were selected as the representative of three dimensions of sustainability. A set of models and sub-models based on the fuzzy inference system were employed to define the index. A case study conducted in two large production farms of maize and wheat, in Iran, proved the feasibility and usability of the model.

    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.

    2015-04-01

    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

  6. Cellulosic ethanol production from agricultural residues in Nigeria

    International Nuclear Information System (INIS)

    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 km3 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 km3 per annum respectively. - Highlights: • Nigeria′s Biofuels Policy mandates a 10% blend of bioethanol with gasoline. • Total bioethanol production from agricultural residues was 7556 km3 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

    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.

  15. Exposures from consumption of agricultural and semi-natural products

    International Nuclear Information System (INIS)

    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

    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}).

    Energy consumption is one of the important symbols of modern agriculture,and it is also an important input in modern agricultural production. The study on the agricultural energy consumption not only has a positive significance to agricultural energy saving,emission reduction and ecological environment protection,but also can greatly reduce the cost of agricultural production and improve the economic benefit of farmers. Through the analysis of the national statistical data about energy consumption for agriculture production from 2005 to 2012 year,the results show that the amount of energy consumption for agricultural production in China has increased year by year since 2005. Because of the continued growth of the total energy consumption in China,the proportion of energy consumption for agricultural production to the total energy consumption of China has declined slightly since 2005. At present,the energy consumption structure for agricultural production in China is diesel fuel,coal,electric power,gasoline,and indirect energy consumption. With the rapid development of the agricultural technology in recent years,the total agricultural output value in China has increased greatly,the direct and indirect agricultural energy consumption per unit of agricultural output value in China has decreased year by year,and the efficiency of energy consumption for agricultural production has increased consequently.

    Full Text Available The sustainable agriculture can bring both environmental and economic benefits for farmers, communities and nations. Sustainable agriculture plays a vital role for poverty alleviation through enhancement of crops and vegetable production. The present study was conducted to compare the production of traditional agriculture (existent with sustainable agriculture and to demonstrate its economic role. The project are (12500 acres consists on both irrigated and non-irrigated land. Keeping in mind the climatic condition, the wheat, maize and different vegetable was cultivated in ways of sustainable agriculture. The wheat production increased from 40-50% on irrigated land but 20-30% on rain-fed land, the maize production enhanced from 20-25% on irrigated land and 10-15% on rain-fed land. Similarly, the vegetable like okra, onion, garlic and tomato production were increased from 30-32% on irrigated land while 28-30% on rain-fed land. If the sustainable agriculture practices are carried out on the whole agriculture land of the project area properly then it is possible that the inhabitants will not only meet the food requirements from their local fields but they will also be able to export to the market of other areas. From experimental result, it is concluded that this practice will reduce the consumption of food requirements and can be used for poverty alleviation.

    2014-01-01

    The existing calculation methods for the number of agricultural surplus labor have a common flaw,that is,they can not reflect the impact of technical efficiency changes in agricultural production on the surplus labor. Based on the basic principle of stochastic frontier production function,this paper calculates the agricultural production technical efficiency of various provinces,and selects the province with the highest technical efficiency to assume that its agricultural labor is fully utilized,and there is no agricultural surplus labor. With the ratio of agricultural labor number to agricultural output value in this province as a reference,this paper calculates the number of agricultural surplus labor in other provinces. This calculation method makes up for the shortcomings of the existing calculation methods; it reflects the relationship between the number of agricultural surplus labor and production technical efficiency.

    1987-12-31

    Agriculture reacts to changes in costs and prices. The allocation of energy, which is a cost factor in agricultural production, is a function of the availability and transportation of its sources. Thus, the use of political incentives, for local production of energy, contributes to the reduction of costs and to create efficiency in agricultural production. A national model was developed to identify: comparative advantages in agricultural production; responses of production to change in prices of products and inputs; impacts of alternative economic policies related to energy, upon production and transportation. 4 refs., 1 tab.

  13. Two agricultural production data libraries for risk assessment models

    International Nuclear Information System (INIS)

    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. Naturally occurring radionuclides in agricultural products: An overview

    International Nuclear Information System (INIS)

    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 106/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

    Full Text Available India is amongst the largest banana (Musa acuminata producing countries and thus banana pseudo stem is commonly available agricultural waste to be used as lignocellulosic substrate. Present study focuses on exploitation of banana pseudo stem as a source for bioethanol production from the sugars released due to different chemical and biological pretreatments. Two fungal strains Aspergillus ellipticus and Aspergillus fumigatus reported to be producing cellulolytic enzymes on sugarcane bagasse were used under co-culture fermentation on banana pseudo stem to degrade holocellulose and facilitate maximum release of reducing sugars. The hydrolysate obtained after alkali and microbial treatments was fermented by Saccharomyces cerevisiae NCIM 3570 to produce ethanol. Fermentation of cellulosic hydrolysate (4.1 g% gave maximum ethanol (17.1 g/L with yield (84% and productivity (0.024 g%/h after 72 h. Some critical aspects of fungal pretreatment for saccharification of cellulosic substrate using A. ellipticus and A. fumigatus for ethanol production by S. cerevisiae NCIM 3570 have been explored in this study. It was observed that pretreated banana pseudo stem can be economically utilized as a cheaper substrate for ethanol production.

    2012-12-01

    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

    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

    Quantification of biogenic carbon fluxes from agricultural lands is needed to generate comprehensive bottom-up estimates of net carbon exchange for global and regional carbon monitoring. We estimated global agricultural carbon fluxes associated with annual crop net primary production (NPP), harvested biomass, and consumption of biomass by humans and livestock. These estimates were combined for a single estimate of net carbon exchange (NCE) and spatially distributed to 0.05 degree resolution using MODIS satellite land cover data. Global crop NPP in 2011 was estimated at 5.25 ± 0.46 Pg C yr-1, of which 2.05 ± 0.05 Pg C yr-1 was harvested and 0.54 Pg C yr-1 was collected from crop residues for livestock fodder. Total livestock feed intake in 2011 was 2.42 ± 0.21 Pg C yr-1, of which 2.31 ± 0.21 Pg C yr-1 was emitted as CO2, 0.07 ± 0.01 Pg C yr-1 was emitted as CH4, and 0.04 Pg C yr-1 was contained within milk and egg production. Livestock grazed an estimated 1.27 Pg C yr-1 in 2011, which constituted 52.4% of total feed intake. Global human food intake was 0.57 ± 0.03 Pg C yr-1 in 2011, the majority of which is respired as CO2. Completed global cropland carbon budgets accounted for the ultimate use of ca. 80% of harvested biomass. The spatial distribution of these fluxes may be used for global carbon monitoring, estimation of regional uncertainty, and for use as input to Earth system models.

    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)

    2012-01-01

    We identified the commercial releases of genetically modified organisms (GMOs) in Brazil, their characteristics, the types of genetic transformation used, and the companies responsible for the development of these GMOs, classifying them into two categories: private companies, subdivided into multinational and national, and public institutions. The data came from the data bank of the national registration of cultivars and the service of national protection of cultivars of the Ministry of Agriculture, Fishing and Supply (MAPA). This survey was carried out from 1998 to February 12, 2011. Until this date, 27 GMOs had been approved, including five for soybean, 15 for maize and seven for cotton cultivars. These GMOs have been used for the development of 766 cultivars, of which, 305 are soybean, 445 are maize, and 13 are cotton cultivars. The Monsato Company controls 73.2% of the transgenic cultivars certified by the MAPA; a partnership between Dow AgroSciences and DuPont accounts for 21.4%, and Syngenta controls 4.96%. Seed supply by these companies is almost a monopoly supported by law, giving no choice for producers and leading to the fast replacement of conventional cultivars by transgenic cultivars, which are expensive and exclude small producers from the market, since seeds cannot be kept for later use. This situation concentrates production in the hands of a few large national agribusiness entrepreneurs. PMID:22869542

  17. Value of Available Global Soil Moisture Products for Agricultural Monitoring

    Science.gov (United States)

    Mladenova, Iliana; Bolten, John; Crow, Wade; de Jeu, Richard

    2016-04-01

    The first operationally derived and publicly distributed global soil moil moisture product was initiated with the launch of the Advanced Scanning Microwave Mission on the NASA's Earth Observing System Aqua satellite (AMSR-E). AMSR-E failed in late 2011, but its legacy is continued by AMSR2, launched in 2012 on the JAXA Global Change Observation Mission-Water (GCOM-W) mission. AMSR is a multi-frequency dual-polarization instrument, where the lowest two frequencies (C- and X-band) were used for soil moisture retrieval. Theoretical research and small-/field-scale airborne campaigns, however, have demonstrated that soil moisture would be best monitored using L-band-based observations. This consequently led to the development and launch of the first L-band-based mission-the ESA's Soil Moisture Ocean Salinity (SMOS) mission (2009). In early 2015 NASA launched the second L-band-based mission, the Soil Moisture Active Passive (SMAP). These satellite-based soil moisture products have been demonstrated to be invaluable sources of information for mapping water stress areas, crop monitoring and yield forecasting. Thus, a number of agricultural agencies routinely utilize and rely on global soil moisture products for improving their decision making activities, determining global crop production and crop prices, identifying food restricted areas, etc. The basic premise of applying soil moisture observations for vegetation monitoring is that the change in soil moisture conditions will precede the change in vegetation status, suggesting that soil moisture can be used as an early indicator of expected crop condition change. Here this relationship was evaluated across multiple microwave frequencies by examining the lag rank cross-correlation coefficient between the soil moisture observations and the Normalized Difference Vegetation Index (NDVI). A main goal of our analysis is to evaluate and inter-compare the value of the different soil moisture products derived using L-band (SMOS

  18. Thinking on Promoting International Trade Competitive Advantage of Agricultural Products in Guangxi Based on CAFTA Framework

    Institute of Scientific and Technical Information of China (English)

    2011-01-01

    This paper analyzes the status quo and the existing problems of international trade development of agricultural products in Guangxi based on CAFTA framework as follows: the international trade of agricultural products in Guangxi shows a trend of rapid growth, but the structure of export products is simple; the distribution of export market is irrational; the export goods are mainly the resources-intensive goods and labor-intensive goods, with low added value of goods; the brand of agricultural products lacks strong overall international competitiveness. In the context of CAFTA framework, in order to foster the international trade competitive advantage of agricultural products in Guangxi, corresponding suggestions are put forward as follows: the structure of export market should change from the current simple status to diversified trend; the structure of export goods should gradually change from the current factor endowment to the orientation of international market demand; the agricultural production should change from the traditional agricultural products to advantageous complementary characteristic agricultural products; the trade structure should change from the land-intensive agricultural products to labor-intensive and technology-intensive agricultural products; the structure of merchandise trade should change from low-price vicious competition to high added-value competition; the governmental function should change from traditional one-way-direction-oriented function to modern integrated-service-and-supervision-oriented function that meets the requirements of export.

    2009-03-25

    The Society for Energy and Environmental Research (SEER) was funded in March 2004 by the Department of Energy, under grant DE-FG-36-04GO14268, to produce a study, and oversee construction and implementation, for the thermo-chemical production of fuel from agricultural and animal waste. The grant focuses on the Changing World Technologies (CWT) of West Hempstead, NY, thermal conversion process (TCP), which converts animal residues and industrial food processing biproducts into fuels, and as an additional product, fertilizers. A commercial plant was designed and built by CWT, partially using grant funds, in Carthage, Missouri, to process animal residues from a nearby turkey processing plant. The DOE sponsored program consisted of four tasks. These were: Task 1 Optimization of the CWT Plant in Carthage - This task focused on advancing and optimizing the process plant operated by CWT that converts organic waste to fuel and energy. Task 2 Characterize and Validate Fuels Produced by CWT - This task focused on testing of bio-derived hydrocarbon fuels from the Carthage plant in power generating equipment to determine the regulatory compliance of emissions and overall performance of the fuel. Task 3 Characterize Mixed Waste Streams - This task focused on studies performed at Princeton University to better characterize mixed waste incoming streams from animal and vegetable residues. Task 4 Fundamental Research in Waste Processing Technologies - This task focused on studies performed at the Massachusetts Institute of Technology (MIT) on the chemical reformation reaction of agricultural biomass compounds in a hydrothermal medium. Many of the challenges to optimize, improve and perfect the technology, equipment and processes in order to provide an economically viable means of creating sustainable energy were identified in the DOE Stage Gate Review, whose summary report was issued on July 30, 2004. This summary report appears herein as Appendix 1, and the findings of the report

    2013-10-01

    Full Text Available One of the problems faced by Romanian agriculture, which concerns both crop production and livestock production, refers to uniformity of the products. Achievement of a high quality standard is as important as maintaining it. Presence of products on the Romanian market depends, primarily, on the ability to group production in different locations within an agreed quality standard. In recent years, over 98% of Romanian agricultural production is obtained in the private sector, yet it has not proved to be the favorable frame of formation and function a competitive market. The causes can be found in the subsistence state of peasant agriculture, due to poor material and technical endowment and lack of a proper management have led to a steady decline in agricultural production. Agricultural production structure has changed significantly in recent years.

    2009-01-01

    China's eastern area is at middle and later stage of industrialization during which the relation between ur ban and rural areas,industry and agriculture appears maladjusted The main problems are shrinkage in agricultural somparative earning and lack of driving force of agricultural development.Based on calculating agricultural labor productivity in east China from 1996 to 2005,this paper analyzes contributing degree of motive forces of agriculture develop in ten provinces and cities of east China applying GCA (Grey correlative analysis).The results show that there is no absolute correspondence between the level of industrialization and agricultural labor productivity in Chi,na's cotstern area.There is no synchronous development between industry and agricultural labor productivity in some areas.Fertilizer and agricultural machinery input had high contributing degree for ten years; however,contributing degree in land and irrigation work input was low.Non-materialization inputs became the leading role in most provinc,es and cities' increase of agricultural labor productivity.Modern agricultural development need non-materializationinputs as primary motive.force,at the same time,direct material input and facility input as guaranteed function.Forsome reasons,agricultural development is characterized by "more direct material input,less facility input" in east China now.Optimal driving force model of future agricultural development in east China is that non-materializatior inputs are dominant that perfected facilitv input are guarantee,and that certain substance inputs are necessary.

  10. The Growth Path of Agricultural Labor Productivity in Major Grain Producing Areas

    Ning; ZHOU; Qifeng; CUI

    2014-01-01

    The growth of agricultural labor productivity in major grain producing areas arises from the increase in production factors or improvement of efficiency,and is related to the sustainability of agricultural economic growth and national food security. We study the growth path of agricultural labor productivity in 13 major grain producing areas of China,and the analysis results show that from the relative endowments of land and labor in major grain producing areas,the growth rate of the output value per unit of labor is higher than that of the productivity per unit of land; in essence,this growth path of increasing the output value relying on increasing the production factor inputs is the reduction of labor,and the reduction of agricultural labor has a great elasticity of impact on the total value of agricultural production. In the case of stable future number of agricultural labor in China,the growth of agricultural labor productivity will be impossible to rely more on the increase in agricultural production factor inputs,and the growth path of agricultural economy still has to rely on the improvement of land productivity and take the efficiency-based path.

Besides,both the inventory level and bullwhip effect of above chain are lowered.

  12. Influence of radioactive contamination to agricultural products by rainfall during a nuclear accident

    International Nuclear Information System (INIS)

    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 131I, and the least sensitive for 90Sr

    2015-01-01

    The development of logistics finance business for agricultural products is the best way to realize the common interests of logistics enterprises,small and medium-sized agricultural product enterprises and financial institutions,which will contribute to the development of China’s new socialist rural economy and the construction of " two-oriented society". As the agricultural products have some special attributes,it’s easy to create the risk in carrying out the logistics finance business. The paper constructs a risk evaluation indicator system for logistics finance of agricultural product,and uses the Fuzzy-AHP model to evaluate. The results show that the comprehensive risk level is normal risk,which shows that third-party logistics enterprises can carry out the logistics financial business of agricultural products,but the risks from logistics enterprises and agricultural collateral need to be prevented.

    Between 2003 and 2005, a total of 11,716 samples were collected and analysed to determine the level of pesticides residues. Multi-residue methods (MRMs) capable of simultaneously determining 250 pesticides were used. Of the 11,716 samples, 89.1% had no detectable residues and 1.7% had violative residues. The detection rates by commodity group were 11.4, 8.6, 0.3, and 0.02% for vegetables, fruit, grain, mushrooms, and the others, respectively. Agricultural products with pesticide residues were pepper, Perilla frutescens, leafy lettuce and spinach in decreasing order. Of the 250 pesticides that were monitored, 70 pesticides were actually found. Procymidone, endosulfan, chlorfenapyr, metalaxyl, and diethofencarb were frequently detected. Of the samples, parsley, Petasites hybridus, Aster scaber and leek had high violative rates of 23.1, 12.6, 8.2, and 7.9%, respectively. From violative samples, procymidone, endosulfan, metalaxyl, diazinon and chlorpyrifos were frequently detected. The violation rates were 1.71, 1.68, and 1.76% in 2003, 2004 and 2005, respectively, and the detection rates were 8.5, 12.0, and 13.3% in 2003, 2004, and 2005, respectively. PMID:24784964

    Full Text Available In Indonesia, agriculture is still one of the business activity that involves many stakeholders with a unique relationship, ranging from farmers as producers, various intermediaries that act to move the product on the retailers who ultimately sell to end consumers. What are the key values connecting between actors to guarantee the continuity of business and how the model linkage or relationship marketing that happens, is the main goal in this paper. The results showed, commitment and trust are the dominant two aspects that underlie the emergence of co-operation as well as the assurance of financial benefit. Another interesting fact revealed by this study is the relationship marketing that occurs not just based on the transactional aspects alone, but there is also a social aspect that binds relationships. This aspect even leads to another fundamental goal, namely the existence of convenience between the parties cooperate. Although both of these goals cannot always be achieved simultaneously due to the strata of different decision-making power, but in reality they complement the ongoing collaboration.Keywords: Commitment, Trust, Transactional and Social Marketing, Leisure

  20. Utilization of steam treated agricultural by -product as ruminant feed

    International Nuclear Information System (INIS)

    Shortage of animal food is a burning issue of the recent time, whereas the agricultural by -products are readily available to be used as ruminants feed. However, the low protein and digestibility are the hindrances in utilization of these low quality crop residues as a feed. In order to utilize rice straw as animal feed this study was conducted to investigate the influence of steam explosion treatment on its composition and in vitro degradability. The samples, I (untreated rice straw), II (rice straw exposed to 15.5 kgf/cm/ sub2/ steam pressure for 90 sec) and III (rice straw exposed to 15.5 kgf/cm/sup 2/steam pressure for 120 sec) were prepared. The results revealed that the crude protein (CP), ether extract (EE) and acid detergent lignin (ADL) contents of rice straw were improved after treatment with steam explosion in time dependent manner (P<0.05). The neutral detergent fiber (NDF), acid detergent fiber (ADF) and organic matter (OM) were higher, while dry matter (DM) and ash contents were lower (P<0.05) in II as compared to group I and III; however, after increasing the time at same pressure these parameters decreased. Furthermore, group III showed higher concentration of propionate, acetate, butyrate, and total VFA (P<0.05). While, group I exhibited higher concentration of iso-butyrate and iso-valerate (P<0.05). The concentration of valeric acid and acetate to propionate ratio were not affected by steam explosion treatment. Moreover, group III showed the higher in vitro DM degradability, OM degradability, DNDF and gas production (P<0.05); while, lower DADF and pH (P<0.05) compared with groups I and II. These findings suggest that the steam explosion treatment at 15.5 kgf/cm/sup 2/ pressure for 120 sec, may be used to enhance the nutritive value and digestibility of rice straw. (author)

    Subtropical grazing lands of peninsular Florida have been shaped by a long evolutionary history of lightning ignited fire followed by flooding resulting in a vast treeless prairie region in south-central Florida. In these grassland ecosystems fire return intervals are between 1-3 years. Beginning in the 1500's, Andalusian cattle began grazing in this region and the cattle industry began in earnest in the late 1800s/early 1900s. Today, Florida's prairie region is largely occupied by cow/calf ranch operations and also occupies the Northern Everglades watershed where water quality/quantity issues are at the forefront of environmental concerns. Florida ranches are characterized by a gradient of management intensities, ranging from sown pastures (most intensively managed) to semi-native pastures with a mix of introduced and native grasses, and rangeland (least managed ecosystem). Located at Archbold Biological Station, MacArthur Agro-ecology Research Center, and University of Florida Range Cattle Research Center (www.maerc.org; www.rcrec-ona.ifas.ufl.edu), a primary goal of the Subtropical Grasslands US Department of Agriculture Long-term Agro-Ecosystem Research LTAR is to balance intensification of sown pastures while enhancing management of native systems in a way that maximizes other ecosystem services (regulating, supporting, cultural, biodiversity). Here, we describe our proposed experimental design to compare ecosystem delivery from conventional and aspirational management regimes in sown pastures and native systems. Aspirational management goals are to (i) maximize productivity in sown pastures with a neutral effect on other ecosystem services, and (ii) manage native systems in a way that maximizes regulating, supporting, and biodiversity ecosystem services by utilizing patch burn grazing. Ultimately, we will determine if enhanced production in sown pasture under the aspirational management system can offset any reduction in productivity in semi

    Full Text Available Extension education is significant range of fields like Agriculture, Natural Resources, Environmental and Bio Diversity Conservation, Rural Development, Home Management Skill Development, Disaster Management, Waste Management, Value Adding Management. Among them, waste management extension is highly significant because of the millions of tons of annual waste in vegetal, animal, environmental and natural resources products as well as millions of hectors of land degradation. Waste management extension deals with raising the efficiency and productivity of the agricultural industry, intellectually and/ or economically. Both producers and consumers should be fully aware of the mechanism by which waste in agricultural commodities diminishes to a considerable level. In agriculture, knowledge and decision-making capacity determine how production factor (i.e. oil, water, capital, chemicals, etc are utilized. Agricultural extension is a focal issue in formulating and disseminating knowledge and helping farmers to be competent decision makers. This article is designed to provide a theoretical and conceptual framework for “agricultural” extension (i.e. mutual agreement between producers and consumers in comprising agricultural waste management to respond to the world-wide expectations for extension to raise agricultural productivity, food production, bio- safety as well as environmental and bio-diversity conservation. Literature review, content analysis and modeling through utilizing contingency tables were employed to conduct the study. Different experiences in this regard have been collected and results show that the greater the use of AWMEE, the less agricultural waste, the higher the agricultural productivity and lower the land degradatioN.

  5. Empirical Research on Influencing Factors of Trade Competitiveness of China’s Agricultural Products

    2011-01-01

    Based on the analysis of the indices of RCA and TSC of agricultural products in China,according to China Statistical Yearbook,China Rural Statistical Yearbook and data from database of The Food and Agriculture Organization of the United Nations from 1996 to 2009,We select direct influencing factors and indirect influencing factors as reference as series of numbers,regard indices of RCA and TSC as index series of numbers of evaluation,and use grey correlation analysis method to conduct analysis and evaluation on influencing factors of trade competitiveness of China’s agricultural products.The results show that due to different index calculation methods,the sequencing results of all factors are not wholly the same.But on the whole,in terms of transformation from cost advantage and price advantage into competition advantage,the ability of direct factors is strong,impacting significantly trade competitiveness of China’s agricultural products,while the influencing effect of indirect factors is relatively weak.On the basis of this,we put forward the suggestions in order to improve trade competitiveness of China’s agricultural products as follows:firstly,we should strengthen and perfect agricultural agriculture-support policy;secondly,we should promote foreign merchants’ direct investment level in agriculture;thirdly,we should deepen the processing ability of agricultural products and promote quality of agricultural products;fourthly,we should create good trade environment.

  10. The water footprint of agricultural products in European river basins

    International Nuclear Information System (INIS)

    This work quantifies the agricultural water footprint (WF) of production (WFprod, agr) and consumption (WFcons, agr) and the resulting net virtual water import (netVWi, agr) of 365 European river basins for a reference period (REF, 1996–2005) and two diet scenarios (a healthy diet based upon food-based dietary guidelines (HEALTHY) and a vegetarian (VEG) diet). In addition to total (tot) amounts, a differentiation is also made between the green (gn), blue (bl) and grey (gy) components. River basins where the REF WFcons, agr, tot exceeds the WFprod, agr, tot (resulting in positive netVWi, agr, tot values), are found along the London–Milan axis. These include the Thames, Scheldt, Meuse, Seine, Rhine and Po basins. River basins where the WFprod, agr, tot exceeds the WFcons, agr, tot are found in Western France, the Iberian Peninsula and the Baltic region. These include the Loire, Ebro and Nemunas basins. Under the HEALTHY diet scenario, the WFcons, agr, tot of most river basins decreases (max −32%), although it was found to increase in some basins in northern and eastern Europe. This results in 22 river basins, including the Danube, shifting from being net VW importers to being net VW exporters. A reduction (max −46%) in WFcons, agr, tot is observed for all but one river basin under the VEG diet scenario. In total, 50 river basins shift from being net VW importers to being net exporters, including the Danube, Seine, Rhone and Elbe basins. Similar observations are made when only the gn + bl and gn components are assessed. When analysing only the bl component, a different river basin pattern is observed. (letters)

  11. Transfer factors of technetium from soil to various agricultural products

    International Nuclear Information System (INIS)

    Laboratory experiments of the transfer of technetium from soil to various kind of agricultural products have been carried out. The soil to plant transfer factors of Tc for rice plants were ≤ 0.005 for the grains and about 1.1 for the lower leaf blade. In contrast to this, higher transfer factors were found for wheat plants i.e. 0.027 for the grains (hulled) and 230 for the lower leaf blade. The Tc concentrations in the grains of both plants were lower than in the leaves. In the case of vegetables, transfer of technetium form soil to edible parts of vegetables have also been studied. Transfer factors of Tc for leaf vegetables such as spinach and komatsuna were considerably higher than those for non-leaf vegetable (e.g carrot, onion, sweet potato, tomato). Values for cabbages and Chinese cabbages were intermediate. Older leaves contained higher Tc than younger ones. It was suggested that Tc was readily taken up through roots and transported with water into leaves without any significant deposition in roots and stems. Technetium accumulated in leaves, while water was transpired from the leaves. This nuclide was associated strongly with constituents in leaves and hardly translocated into the other parts of the plants such as tubers, bulbs and fruits. The transfer factors (on a wet weight basis) in edible parts of vegetables obtained in this study were as follows; cabbage: 0.3, Chinese cabbage: 0.1, spinach: 2.4, komatsuna: 1.1, carrot: 0.3, onion: 0.05, sweet potato: 0.03 and tomato: 0.03.

    Full Text Available The production of public goods like amenity value of the landscape, food security, preservation of rural communities and rural lifestyle, by agricultural sector is a subject that has been widely accepted by experts. However, in many policies and political analyses carried out, solely the production of private goods by the agricultural sector is paid attention and the important function of public goods production is ignored. Given the importance of multifunctional debate of agriculture in policies analysis, this study examined the effect of agricultural multifunctionality in the simulation of the agricultural production subsidiesreduction effects using Computable General Equilibrium (CGE model. Simulation results of the effects of agricultural production subsidies reduction in terms of the multifunctionality showed that current practices to support the agricultural sector is non-optimal according to agricultural production and welfare reduction and the optimal level of supports with and without multifunctional agriculture is different. The simulation results showed that the welfare effects of economic reforms in Iran in the agricultural sector in terms of the multifunctionality will be positive. This is on condition that the welfare effects of agricultural reform in terms of the multifunctionality of agriculture are negative.

    2016-08-01

    Pectin containing agricultural by-products are potential sources of a new class of prebiotics known as pectic oligosaccharides (POS). In general, pectin is made up of homogalacturonan (HG, α-1,4-linked galacturonic acid monomers) and rhamnogalacturonan (RG, alternate galacturonic acid and rhamnose backbone with neutral side chains). Controlled hydrolysis of pectin containing agricultural by-products like sugar beet, apple, olive and citrus by chemical, enzymatic and hydrothermal can be used to produce oligo-galacturonides (GalpOS), galacto-oligosaccharides (GalOS), rhamnogalacturonan-oligosaccharides (RGOS), etc. However, extensive research is needed to establish the role of POS, both as a prebiotic as well as therapeutic agent. This review comprehensively covers different facets of POS, including the nature and chemistry of pectin and POS, potential agricultural residual sources of pectin, pre-treatment methods for facilitating selective extraction of pectin, identification and characterization of POS, health benefits and important applications of POS in food and feed. This review has been compiled to establish a platform for future research in the purification and characterization of POS and for in vivo and in vitro studies of important POS, so that they could be commercially exploited.

    International Nuclear Information System (INIS)

    We collected natural and sociological environmental data related to the estimation of radiation dose by radionuclides which will be released from atomic energy facilities. Published data concerned with production and distribution in Aomori Prefecture were collected and compiled for rice and root vegetables. Produced weight per unit field area (production density) and time ratio of cultivation period to a year were estimated by using the compiled data. We also tried to estimate market dilution coefficients for the agricultural products mentioned above from distribution data in the prefecture under some assumptions. Estimated means of the parameters were safer ones for rice than those used in the environmental assessment for the reprocessing plant now under construction in Rokkasho Village by JNFL. The mean values for root vegetables were equal to, or on the safer side, than those used in the assessment. We collected nine reports in the literature related to reducing transfer of radionuclide to fishery products and their decontamination. (author)

  10. Agriculture and food production after a nuclear power accident

    International Nuclear Information System (INIS)

    In a situation with radioactive fall-out in agricultural areas in Sweden, many organisations will be engaged. The authorities in the field of agriculture and food will give advices and recommendations, the producers will see to their interests, the consumers will react and researchers and experts will be engaged. A combined game and seminar was carried through in the city of Huskvarna 17 - 18 March, 1998 with participation from the responsible authorities: Swedish Board of Agriculture, National Food Administration, Swedish Radiation Protection Institute and from producers, organisations and the government and with researchers and people from contract laboratories. The game and seminar was based upon a scenario with a release of radioactivity from the nuclear power plant of Ignalina in early July and focused on the threat phase and the time close to the deposition. The release and the weather condition resulted in a deposition of 137Cs and 131I in agricultural areas in southern Sweden. The biggest levels of deposition took place in the county of Oestergoetland, where the resulting levels were three times the highest levels in Sweden after the Chernobyl-accident The seminar combined lectures, group-work and discussions and actualised a great number of issues that should be further investigated. The report ends with a factual part about possible countermeasures in agriculture

    2014-01-01

    Increasing population size and demand for food in the developing world is driving the intensification of agriculture, often threatening the biodiversity within the farmland itself and in the surrounding landscape. This paper quantifies bird and tree species richness, tree carbon and farmer's gross...... income, and interactions between these four variables, across an agricultural gradient in central Uganda. We showed that higher cultivation intensities in farmed landscapes resulted in increased income but also a decline in species richness of birds and trees, and reductions in tree carbon storage....... These declines were particularly marked with a shift from high intensity smallholder mixed cropping to plantation style agriculture. This was especially evident for birds where significant declines only occurred in plantations. Small scale farming will likely continue to be a key source of cash income...

    Based on the data related to the Chinese and world agricultural production and trade from 1986 to 2011,this paper uses the principal component analysis,cointegration and vector error correction model to perform the empirical analysis of the impact of processing,import and export of agricultural products on the agricultural modernization in China. The results show that the processing and export of agricultural products play a role in promoting the agricultural modernization in China,while the import of agricultural products has some negative effects on the agricultural modernization in China. The negative effects of the import of agricultural products are from the limitations of farmers’ small-scale operation and foreign trading partners’ protectionism. China should further develop the processing industry of agricultural products,and strengthen the role of downstream industries in promoting the agricultural modernization; improve the level of large-scale and intensive operation,and make good use of WTO rules,in order to provide the necessary market conditions for the agricultural modernization.

    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.

    Full Text Available To solve the capability coordination in logistics service based on the agricultural products industry, a two-stage agricultural products Logistics Service Supply Chain (LSSC was established with one agricultural products logistics service integrator and one functional logistics service provider. Based on the non-storage property of logistics service capability, the revenue-sharing contract model was built under the uncertain demand. The optimal logistics capability order quantity and the revenue-sharing coefficient were calculated when the agricultural products LSSC achieved coordination. Revenue-sharing contract can coordinate the agricultural products LSSC effectively compared with no contract. A numerical simulation was taken by MATLAB 7.0. The change of purchase price has no influence on the optimal logistics capability order quantity and the expected profit of agricultural products LSSC. It achieves a redistribution of members’ profits. With the increases of penalty cost, the optimal logistics capability order quantity and the expected profit of provider increase, while the expected profit of integrator and agricultural products LSSC decrease.

    2011-07-01

    In this article, we study the inventory replenishment model for perishable agricultural products in a simple two-level supply chain. Collaborative forecasting is introduced into the inventory replenishment decisions to avoid overstocking and understocking of agricultural products, and to maximise profits. We analyse the model with ordering cost, holding cost, shortage cost, deterioration cost and opportunity lost cost of perishable agricultural products. Extensive numerical analysis is carried out to study the performance of the inventory policy. The optimal replenishment policy that minimises the total cost can be obtained from the model. It has demonstrated that the supply chain cost decreases with supplier and retailer's collaborative forecasting.

  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.

    Girgin, T.; Ozdogan, M.

    2015-12-01

    Until recently, agricultural production in Syria has been an important source of revenue and food security for the country. At its peak, agriculture in Syria accounted for 25 percent of the country's GDP. In 2014, Syrian agriculture accounted for less than 5 percent of the GDP. This decline in agricultural productivity is the cause of a 3-year long drought that started in 2007, followed by a still-ongoing conflict that started in mid-2011. Using remote sensing tools, this paper focuses on the impact that the 2007-2010 drought had on agricultural production, as well as the impact that the ongoing conflict had on the agricultural production in northern Syria. Remote sensing is a powerful and great solution to study regions of the world that are hard-to-reach due to conflict and/or other limitations. It is particularly useful when studying a region that inaccessible due to an ongoing conflict, such as in northern Syria. Using multi-temporal Landsat 5 and Landsat 8 images from August 2006, 2010 and 2014 and utilizing the neural networks algorithm, we assessed for agricultural output change in northern Syria. We conclude that the ongoing Syrian conflict has had a bigger impact on the agricultural output in northern Syria than the 3-year long drought.

    Agricultural production both contributes to and responds to climatic variations across spatial and temporal continuums. The agriculture sector is responsible for over 6% of total U.S. greenhouse gas emissions, primarily as methane (CH4) and nitrous oxide (N2O) gases emitted by agricultural activities. Agriculture activities specifically account for about 69% of U.S. N2O emissions, largely as a result of production practices including fertilizer management, cropping systems, and manure management. Fertilizers, together with manure and legume fixation, are the three main inputs of N to US agricultural soils. All three sources have been increasing over the past two decades, while the rate at which they are removed in the form of harvested crops has been increasing at a slightly slower rate. The outlook for continued large areas of cultivation in the U.S., specifically for corn production and supported by biofuel production goals, is a major factor in sustaining demand for N fertilizer. However, rising fertilizer prices and environmental pressures on producers are encouraging increased adoption of emerging technologies such as precision agriculture, cultivars with higher N use efficiency, and enhanced-efficiency N sources such as controlled-release forms or forms with urease or nitrification inhibitors. Crop productivity also responds to climatic changes, as crop growth is affected by variables including heat, drought, ozone (O3), and increased ambient carbon dioxide (CO2). We summarize sources and fates of N for cropping systems and intensive animal systems and assess how climate change will affect crop response to and recovery of N and subsequent cascading effects on Nr. The complex interactions between agricultural Nr and climate present opportunities for mitigation/adaption relative to N use. N fertilizer and manure management, tillage, technology, and decision support models provide significant opportunities for climate mitigation and adaption in U.S. agriculture

  10. Fields of dreams: Agriculture, economy and nature in Midwest United States biofuel production

    Science.gov (United States)

    Gillon, Sean Thomas

    This work explores the social and ecological dimensions of recent biofuel production increases in the United States (US), focusing on the case of Iowa. Biofuels are proposed to mitigate the greenhouse gas emissions that cause climate change, improve US energy security, and support rural economies. Little research has examined how increased US Midwestern biofuels production will change social and ecological outcomes at farm and regional levels or interact with broader governance processes at the nexus of agriculture, energy and environment. These broad questions guide my research: (1) How does biofuel production reconfigure agricultural practice and landscapes in Iowa? (2) What are the costs, benefits and risks of increased biofuels production as seen by farmers and rural residents, and how do these factors influence farmer decisions about agriculture and conservation practice? (3) How and with what effects are biofuels initiatives constituted as a form of environmental governance through scientific knowledge and practice and political economic dynamics? To address these questions, this research integrates both qualitative and quantitative methods, drawing on a political ecological approach complemented by agroecological analysis and theoretical insights from geographical analyses of nature-society relations. Quantitative analysis focuses on changing land use patterns in agriculture and conservation practice in Iowa. Qualitative methods include extensive interviews, participant observation, and policy and document analyses. Fieldwork focused on Northeastern Iowa to understand regional changes in agricultural and conservation practice, the renegotiated position of farmers in agriculture and biofuel production, and biofuel industry development. I find that biofuel production presents significant social and ecological challenges for rural places of production. Longstanding, unequal political economic relations in industrialized agriculture limit rural economic benefits

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

    International Nuclear Information System (INIS)

    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.

  18. Macroeconomic impacts of bioenergy production on surplus agricultural land. A case study of Argentina

    International Nuclear Information System (INIS)

    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.

  20. The production and utilization of by-product agricultural fertilizer from flue gases

    International Nuclear Information System (INIS)

    The electron-beam process is one of the most effective methods for removing SO2 and NOx 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 SO2 and NOx 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 SO2 and NOx emission reduction activity

  1. Ethanol and agriculture: Effect of increased production on crop and livestock sectors. Agricultural economic report

    International Nuclear Information System (INIS)

    Expanded ethanol production could increase US farm income by as much as $1 billion (1.4 percent) by 2000. Because corn is the primary feedstock for ethanol, growers in the Corn Belt would benefit most from improved ethanol technology and heightened demand. Coproducts from the conversion process (corn gluten meal, corn gluten feed, and others) compete with soybean meal, soybean growers in the South may see revenues decline. The US balance of trade would improve with increased ethanol production as oil import needs decline

    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.

    2006-10-01

    Full Text Available Agricultural Institute of Slovenia was performing national monitoring for pesticide residues in agricultural products according to the Decree on Monitoring of Pesticides in Foodstuffs and in Agricultural Products (Offi cial Gazette of the Republic of Slovenia No. 13/99. Constant measurements are necessary due to intensive agricultural production and use of chemical substances for plant protection. Due to the nutrition characteristic for the Slovenians pesticide residues are monitored each year in the samples of potato, lettuce and apples; the choice of other agricultural products and active substances analysed are adapted to the guidelines indicated in the EU recommendations. In the years 2003 and 2004 we analysed the presence of pesticide residues in 361 samples of agricultural products: caulifl ower, head cabbage, grapes, apples, strawberries, potatoes, peppers, tomatoes, wheat and lettuce from eight different growing areas of Slovenia. All agricultural products were analysed in 2003 for the presence of 51 active substances and in 2004 for the presence of 57 active substances. The maximum residue level (MRL was exceeded by 6.6 % samples inspected. Potato contributed a major share to this, since in 5.0 % of samples exceeded values of dithiocarbamate residues were determined, however, they were the only active substance found in potato. In 39.1 % of analysed samples residues lower than MRL were determined, in 54.3 % of samples residues were not found or they were below the level of detection method. The greatest number of pesticide residues which did not exceed MRLs was found in fruit, f. ex.: eight in apples and six in strawberries. Residues of dithiocarbamates were the most frequently found active substance in agricultural products.

  5. Food, Feed, or Fuel? Phosphorus Flows Embodied in US Agricultural Production and Trade

    Science.gov (United States)

    MacDonald, G.; Bennett, E.; Carpenter, S.

    2012-12-01

    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.

  9. Weather based risks and insurances for agricultural production

    Science.gov (United States)

    Gobin, Anne

    2015-04-01

    Extreme weather events such as frost, drought, heat waves and rain storms can have devastating effects on cropping systems. According to both the agriculture and finance sectors, a risk assessment of extreme weather events and their impact on cropping systems is needed. The principle of return periods or frequencies of natural hazards is adopted in many countries as the basis of eligibility for the compensation of associated losses. For adequate risk management and eligibility, hazard maps for events with a 20-year return period are often used. Damages due to extreme events are strongly dependent on crop type, crop stage, soil type and soil conditions. The impact of extreme weather events particularly during the sensitive periods of the farming calendar therefore requires a modelling approach to capture the mixture of non-linear interactions between the crop, its environment and the occurrence of the meteorological event in the farming calendar. Physically based crop models such as REGCROP (Gobin, 2010) assist in understanding the links between different factors causing crop damage. Subsequent examination of the frequency, magnitude and impacts of frost, drought, heat stress and soil moisture stress in relation to the cropping season and crop sensitive stages allows for risk profiles to be confronted with yields, yield losses and insurance claims. The methodology is demonstrated for arable food crops, bio-energy crops and fruit. The perspective of rising risk-exposure is exacerbated further by limited aid received for agricultural damage, an overall reduction of direct income support to farmers and projected intensification of weather extremes with climate change. Though average yields have risen continuously due to technological advances, there is no evidence that relative tolerance to adverse weather events has improved. The research is funded by the Belgian Science Policy Organisation (Belspo) under contract nr SD/RI/03A.

    In recent years,Guangxi realized consecutive bumper harvests in fresh agricultural products,leading increase of logistics demand;logistics infrastructure begins to take shape,and logistics of fresh agricultural products takes on diversified development form with wholesale market as main form. However,traditional fresh agricultural products are not selling well and it lacks construction of supply chain; the construction of logistics information system for fresh agricultural products lags behind; organizational level of production and operation of fresh agricultural products is low. Through analyzing current situations and existing problems of logistics of Guangxi fresh agricultural products in the new period( 21 st century),this paper came up with recommendations for developing logistics of fresh agricultural products of Guangxi. Government should increase policy and financial support,build and manage supply chain of fresh agricultural products,accelerate construction of logistics information system for agricultural products,and improve organizational level of logistics of fresh agricultural products,to ensure healthy development of logistics of fresh agricultural products in Guangxi.

    Systems-level analyses have become prominent tools for assessing the yield, viability, economic consequences and environmental impacts of agricultural production. Such analyses are well-developed for many commodity crops that are used for food and biofuel, but have not been developed for agricultural production systems based on drought-tolerant plants that use crassulacean acid metabolism (CAM). We review the components of systems-level evaluations, and identify the information available for completing such analyses for CAM cropping systems. Specific needs for developing systems-level evaluations of CAM agricultural production include: improvement of physiological models; assessment of product processing after leaving the farm gate; and application of newly available genetic tools to the optimization of CAM species for commercial production.

    Full Text Available This study aims to investigate the dual-class tax impacts on China agricultural products using the parallel factor analysis. Along with the rapid economic development of China, the growing purchasing power of Chinese residents has been accelerated; particularly in the expensive agricultural products market. China has adjusted taxable items of consumption tax to narrow the gap between rich and poor and to promote social equity. The atrophy of the expensive agricultural products market brought by the tax may curb the growth and development of domestic agricultural products industry. In this study, the parallel factor analysis is employed to investigate the dual-class tax impacts on China agricultural products. The results indicate that the taxation system should be taken from a forward-looking aspect. The market supply and demand for expensive agricultural products and consumer behaviors should be combined with an overall consideration. Hence, specific adjustments China expensive agricultural products market have been eventually put forward.

    2014-05-01

    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.

  19. The Concept of Agricultural Productivity on Ecosystem Scale and Its Measurement

    2006-01-01

    What is the connotation and the extension of the productivity concept and how to calculate it are the core problems in evaluating an agricultural-production process. The attributes of agricultural production processes have changed greatly in the last 100 years, and the methods to describe and measure the productivity failed to keep in pace with the production processes, resulting in a totally vague, incomplete evaluation of the production processes. Sometimes the serious problem of pollution is ignored in the race to shortdated money making, thus leading to a blooming and flooding pollution;sometimes the great ecological benefits are ignored and the corresponding production processes suffer drastically from "economic deficit". With the old agricultural productivity indices, no prediction can be made of the ultimate effects of agroecosytem on mankind-pollution or welfare. A new concept, agricultural productivity on ecosystem scale (APES) and the related indices are defined here to solve these problems. Emergy and exergy are introduced to help the measurement of the indices. Emergy is the memory of energy, which can be used to measure the total cost, including natural capital and social capital. APES of the agroecosystem is the aggregated contributions of all components to mankind and its habitat in uniformed dimensions, it may be expressed in material, energy, information, organization, pollution and damage, etc., positive or negative, and are calculated based on exergy methods. And a related index agroecological coupling degree (ACD) shows sustainability.

  15. Decoupling of greenhouse gas emissions from global agricultural production: 1970-2050.

    Science.gov (United States)

    Bennetzen, Eskild H; Smith, Pete; Porter, John R

    2016-02-01

    Since 1970 global agricultural production has more than doubled; contributing ~1/4 of total anthropogenic greenhouse gas (GHG) burden in 2010. Food production must increase to feed our growing demands, but to address climate change, GHG emissions must decrease. Using an identity approach, we estimate and analyse past trends in GHG emission intensities from global agricultural production and land-use change and project potential future emissions. The novel Kaya-Porter identity framework deconstructs the entity of emissions from a mix of multiple sources of GHGs into attributable elements allowing not only a combined analysis of the total level of all emissions jointly with emissions per unit area and emissions per unit product. It also allows us to examine how a change in emissions from a given source contributes to the change in total emissions over time. We show that agricultural production and GHGs have been steadily decoupled over recent decades. Emissions peaked in 1991 at ~12 Pg CO2 -eq. yr(-1) and have not exceeded this since. Since 1970 GHG emissions per unit product have declined by 39% and 44% for crop- and livestock-production, respectively. Except for the energy-use component of farming, emissions from all sources have increased less than agricultural production. Our projected business-as-usual range suggests that emissions may be further decoupled by 20-55% giving absolute agricultural emissions of 8.2-14.5 Pg CO2 -eq. yr(-1) by 2050, significantly lower than many previous estimates that do not allow for decoupling. Beyond this, several additional costcompetitive mitigation measures could reduce emissions further. However, agricultural GHG emissions can only be reduced to a certain level and a simultaneous focus on other parts of the food-system is necessary to increase food security whilst reducing emissions. The identity approach presented here could be used as a methodological framework for more holistic food systems analysis. PMID:26451699

    The torrential rain and strong wind brought by typhoons usually cause huge damages to agricultural products. This study aims at hazard map of agricultural products due to typhoons. The factors affecting the hazard of agricultural products due to typhoons include the duration of flooding, flooding depth, wind speed, and rainfall intensity. High rainfall intensity and high wind speed may knock down the leaves or fruits of the plants. The long-duration of flooding or high flooding depth may chock the plant or rotten the roots. In order to get the information needed for making hazard map due to assumed scenarios, an overland flow simulations is performed for getting the duration of flooding and maximum flooding in the study area. The data of wind speed is obtained from metrological stations. Four levels of hazard are defined due to the characteristic of the chosen agricultural products- Bok-choy (such average height of mature Bok-choy). The final goal of this study is to establish a real-time hazard evaluation system for the specific agricultural products.

  17. Research on Site Selection Model of Distribution Center of Agricultural Products

    Institute of Scientific and Technical Information of China (English)

    2011-01-01

    In the light of the practical situation of logistics distribution of agricultural products,we primarily select transportation factor,economic factor,environment factor,and other factors,to establish evaluation index system of site selection of distribution center of agricultural products.And then we adopt the analytic hierarchy process method to calculate weight of site selection of distribution center of agricultural products.Under the circumstance that the evaluation information is interval number,we use uncertain and multiple attribute decision making method to establish site selection model of distribution center of agricultural products.Finally,taking one city as an example,we discuss the application of this model in site selection of distribution center of agricultural products.The results of empirical analysis show that the model we established fully considers the randomness and uncertainty in the process of evaluation,so as to make the results of evaluation more objective,in line with reality.So the effect of evaluation is better as against the former real number evaluation calibration.

  20. Changes in 137Cs transfer to agricultural products

    International Nuclear Information System (INIS)

    The food production and food harvesting systems common in the areas contaminated by the Chernobyl accident in Republic of Belarus can be grouped into three major categories: collective farm produce, private farming produce and natural foods collected from natural ecosystems. The collective farm system provided the smallest contribution (8-12 %) to the intake of 137Cs. Natural food was the major contributor to the intake at one study site (73 %), and private produce was the major contributor (60 %) at the other study site. Assessment of the situation just after the accident (one year) shows that collective farming was still a minor contributor to 137CS intake (10 %) whilst private fanning would have been the major contributor wherever private milk production and consumption continued. The extent to which inhabitants consume natural foods from forests has a considerable effect on their 137CS intake. The comparative importance of food products from natural ecosystems increases with time due to the long effective ecological half lives of 137Cs in unimproved pastures and forests. Estimation of the contribution to the fluxes of 137Cs from the different production and harvesting systems showed that the contribution from private farming and food harvesting from natural ecosystems may also be significant, contributing 14-30 % to the total fluxes of 137Cs from an area even if the quantity of food produced in these systems is small. However, the major contributor to the flux exported from an area was the collective farming system, accounting for about 70-86 % of the total. Refs. 12 (author)

  1. Agricultural conversion without external water and nutrient inputs reduces terrestrial vegetation productivity

    Smith, W. Kolby; Cleveland, Cory C.; Reed, Sasha C.; Running, Steven W.

    2014-01-01

    Driven by global population and standard of living increases, humanity co-opts a growing share of the planet's natural resources resulting in many well-known environmental trade-offs. In this study, we explored the impact of agriculture on a resource fundamental to life on Earth: terrestrial vegetation growth (net primary production; NPP). We demonstrate that agricultural conversion has reduced terrestrial NPP by ~7.0%. Increases in NPP due to agricultural conversion were observed only in areas receiving external inputs (i.e., irrigation and/or fertilization). NPP reductions were found for ~88% of agricultural lands, with the largest reductions observed in areas formerly occupied by tropical forests and savannas (~71% and ~66% reductions, respectively). Without policies that explicitly consider the impact of agricultural conversion on primary production, future demand-driven increases in agricultural output will likely continue to drive net declines in global terrestrial productivity, with potential detrimental consequences for net ecosystem carbon storage and subsequent climate warming.

  2. Analysis of Changes in Energy Consumption and Demand Trend in China’s Agricultural Production

    Institute of Scientific and Technical Information of China (English)

    2011-01-01

    China’s energy consumption for agricultural production has relied on petroleum and coal with relatively low input from power and other types of energy for a long time.Projections indicate that as China’s existing development trend leads to substantial growth of energy demand for agricultural production,such a long term irrational energy consumption pattern would unlikely be able to meet the needs of the country’s developing agricultural sector.As such,it is recommended that China’s agricultural sector should follow the national energy development strategy guideline by gradually increasing the use of wind power,solar energy,biomass and other new energy sources while advancing technological innovations on traditional energy sources.Meanwhile,as the consumption structure of three major energy sources(i.e.petroleum,coal,and power)is optimized,development and application of biomass from agriculture as raw materials for alternative energy should be enhanced.Lastly,the development and application of wind power,solar energy,and hydropower in agricultural production should be increased in areas where appropriate.

  3. Livestock in a changing climate: production system transitions as an adaptation strategy for agriculture

    International Nuclear Information System (INIS)

    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 CO2 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.

    The Sina river basin is facing both episodic and chronic water shortages due to intensive irrigation development. The main objective of this study was to characterize the hydrologic processes of the Sina river basin and assess crop water productivity using the distributed hydrologic model, SWAT. In the simulation year (1998-1999), the inflow to reservoir from upstream side was the major contributor to the reservoir accounting for 92 % of the total required water release for irrigation purpose (119.5 Mm3), while precipitation accounted for 4.1 Mm3. Annual release of water for irrigation was 119.5 Mm3 out of which 54 % water was diverted for irrigation purpose, 26 % was wasted as conveyance loss, average discharge at the command outlet was estimated as 4 % and annual average ground-water recharge coefficient was in the range of 13-17 %. Various scenarios involving water allocation rule were tested with the goal of increasing economic water productivity values in the Sina Irrigation Scheme. Out of those, only most benefited allocation rule is analyzed in this paper. Crop yield varied from 1.98 to 25.9 t/ha, with the majority of the area between 2.14 and 2.78 t/ha. Yield and WP declined significantly in loamy soils of the irrigation command. Crop productivity in the basin was found in the lower range when compared with potential and global values. The findings suggested that there was a potential to improve further. Spatial variations in yield and WP were found to be very high for the crops grown during rabi season, while those were low for the crops grown during kharif season. The crop yields and WP during kharif season were more in the lower reach of the irrigation commands, where loamy soil is more concentrated. Sorghum in both seasons was most profitable. Sorghum fetched net income fivefold that of sunflower, two and half fold of pearl millet and one and half fold of mung beans as far as crop during kharif season were concerned and it fetched fourfold that of

    Over the years,the logistics development in Tibet has fallen behind the transport. Since the opening of Qinghai-Tibet Railway in2006,the opportunity for development of modern logistics has been brought to Tibet. The logistics demand analysis and forecasting is a prerequisite for regional logistics planning. By establishing indicator system for logistics demand of agricultural products,agricultural product logistics principal component regression model,gray forecasting model,BP neural network forecasting model are built. Because of the single model’s limitations,quadratic-linear programming model is used to build combination forecasting model to predict the logistics demand scale of agricultural products in Tibet over the next five years. The empirical analysis results show that combination forecasting model is superior to single forecasting model,and it has higher precision,so combination forecasting model will have much wider application foreground and development potential in the field of logistics.

  10. A Study on Regional Specialization of China’s Agricultural Production: Recent Trends and Drivers

    Full Text Available The paper examines trends and drivers for regional specialization of China’s agricultural produc-tion for 2003-2011. We apply the Regional Specialization Index to a data set of commodities that covers 70 percent of China’s crop and livestock production. Actual prices at the provincial level are used and a seven-region framework is established that accurately reflects China’s agro-ecological characteristics. Our findings show that inequality of specialization among the Chinese regions has narrowed, with the year 2007 as a turning point. We argue that the enhanced regional specialization is due to less government intervention and more openness to international markets. Growing economic freedom, accompanied by intensified internal and external competition, has driven the regions to adjust agricultural production structures closely according to comparative advantages. Recent trends of specialization are identified and explained. Moreover, quantitative evidence to relevant agricultural policies is provided.

    Projections of temperature and precipitation patterns across the United States during the next 50 years anticipate a 1.5 to 2°C warming and a slight increase in precipitation as a result of global climate change. There have been relatively few studies of climate change impacts on pasture and rangeland (grazingland) species compared to those on crop species, despite the economic and ecological importance of the former. Here we review the literature on pastureland and rangeland species to rising CO2 and climate change (temperature, and precipitation) and discuss plant and management factors likely to influence pastureland and rangeland responses to change (e.g., community composition, plant competition, perennial growth habit, seasonal productivity, and management methods). Overall, the response of pasture species to increased [CO2] is consistent with the general response of C3 and C4 type vegetation, although significant exceptions exist. Both pastureland and rangeland species should exhibit an acceleration of metabolism and development due to earlier onset of spring green-up and longer growing seasons. However, in the studies reviewed here, C3 pasture species increased their photosynthetic rates by up to 40% while C4 species exhibited no increase in photosynthesis. In general, it is expected that increases in [CO2] and precipitation would enhance rangeland net primary production (NPP) while increased air temperatures would either increase or decrease NPP. Much of this uncertainty in response is due to uncertain future projections of precipitation, both globally and regionally. For example, if annual precipitation changes little or declines, rangeland plant response to warming temperatures and rising [CO2] may be neutral or may decline due to increased water stress. This review reveals the need for comprehensive studies of climate change impacts on the pasture ecosystem including grazing regimes, mutualistic relationships (e.g., plant roots-nematodes; N

    An HPLC analytical method was validated for the quantitative determination of biogenic amines in agricultural products. Four agricultural foods, including apple juice, Juk, corn oil and peanut butter, were selected as food matrices based on their water and fat contents (i.e., non-fatty liquid, non-fatty solid, fatty liquid and fatty solid, respectively). The precision, accuracy, recovery, limit of detection (LOD) and quantification (LOQ) were determined to test the validity of an HPLC procedure for the determination of biogenic amines, including tryptamine, β-phenylethylamine, putrescine, cadaverine, histamine, tyramine, spermidine and spermine, in each matrix. The LODs and LOQs for the biogenic amines were within the range of 0.01~0.10 mg/kg and 0.02~0.31 mg/kg, respectively. The relative standard deviation (RSD) of intraday for biogenic amine concentrations ranged from 1.86 to 5.95%, whereas the RSD of interday ranged from 2.08 to 5.96%. Of the matrices spiked with biogenic amines, corn oil with tyramine and Juk with putrescine exhibited the least accuracy of 84.85% and recovery rate of 89.63%, respectively, at the lowest concentration (10 mg/kg). Therefore, the validation results fulfilled AOAC criteria and recommendations. Subsequently, the method was applied to the analysis of biogenic amines in fermented agricultural products for a total dietary survey in Korea. Although the results revealed that Korean traditional soy sauce and Doenjang contained relatively high levels of histamine, the amounts are of no concern if these fermented agricultural products serve as condiments.

    In this project, Mayaterials developed a low cost, low energy and low temperature method of purifying rice hull ash to high purity (5-6Ns) and converting it by carbothermal reduction to solar grade quality silicon (Sipv) using a self-designed and built electric arc furnace (EAF). Outside evaluation of our process by an independent engineering firm confirms that our technology greatly lowers estimated operating expenses (OPEX) to $5/kg and capital expenses (CAPEX) to $24/kg for Sipv production, which is well below best-in-class plants using a Siemens process approach (OPEX of 14/kg and CAPEX of $87/kg, respectively). The primary limiting factor in the widespread use of photovoltaic (PV) cells is the high cost of manufacturing, compared to more traditional sources to reach 6 g Sipv/watt (with averages closer to 8+g/watt). In 2008, the spot price of Sipv rose to $450/kg. While prices have since dropped to a more reasonable $25/kg; this low price level is not sustainable, meaning the longer-term price will likely return to $35/kg. The 6-8 g Si/watt implies that the Sipv used in a module will cost $0.21-0.28/watt for the best producers (45% of the cost of a traditional solar panel), a major improvement from the cost/wafer driven by the $50/kg Si costs of early 2011, but still a major hindrance in fulfilling DOE goal of lowering the cost of solar energy below $1/watt. The solar cell industry has grown by 40% yearly for the past eight years, increasing the demand for Sipv. As such, future solar silicon price spikes are expected in the next few years. Although industry has invested billions of dollars to meet this ever-increasing demand, the technology to produce Sipv remains largely unchanged requiring the energy intensive, and chlorine dependent Siemens process or variations thereof. While huge improvements have been made, current state-of-the-art industrial plant still use 65 kWh/kg of silicon purified. Our technology offers a key distinction to other technologies as it

    Full Text Available The main objective of this study was production of ethanol from three lignocellulosic biomasses like sugarcane bagasse, rice straw and wheat straw by Sacchromyces cervisae. All the three substrates were ground to powder form (2 mm and pretreated with 3%H2O2 + 2% NaOH followed by steaming at 130 °C for 60 min. These substrates were hydrolyzed by commercial cellulase enzyme. The whole fermentation process was carried out in 500 mL Erlenmeyer flask under anaerobic conditions in submerged fermentation at 30 °C for three days of incubation period. FTIR analysis of the substrates indicated significant changes in the alteration of the structure occurred after pretreatment which leads to efficient saccharification. After pretreatment the substrates were hydrolyzed by commercial cellulase enzyme and maximum hydrolysis was observed in sugarcane bagasse (64% followed by rice straw (40% and wheat straw (34%. Among all these tested substrates, sugarcane bagasse (77 g/L produced more ethanol as compared to rice straw (62 g/L and wheat straw (44 g/L using medium composition of (% 0.25 (NH42SO4, 0.1 KH2PO4, 0.05 MgSO4, 0.25 Yeast extract by S. cervisae.

    Full Text Available The Tofu Liquid Waste (TLW as a pollution might be processed into biogas which was environmentally friendly and had potential to replace burning wood or oil. However, the waste could not directly be employed as the biogas substrate due to the high nitrogen content which was not suitable to the methanogen microorganism on the biogas digester and did not produce biogas. It was therefore necessary to adapt the carbon-nitrogen ratio in TLW with the addition of other organic materials that had a lower nitrogen content so it would be a suitable substrate for generating biogas. The research was aimed to evaluate the addition of the other organic material on the TLW to increase the biogas production. The results showed that TLW combined with sheep dung, cabbage waste, bamboo leaves and paddy straw respectively produced biogas as much as 14,183, 7,250, 2,400, 895 cm3 in 20 days. The 4 treatments gave the same quality of biogas, which was determined using the water boiling test. The pH fluctuation during the process was in the right pH for anaerobic digestion, thus it was not the limiting factor.

    Directory of Open Access Journals (Sweden)

    Kolupaev S. V.

    2015-10-01

    Full Text Available The development of agricultural production inevitably entails an increasing volume of traffic and a turnover of goods. Therefore, the issues of increasing transport efficiency, reducing the price of transportations and improving productivity acquire great importance. In most cases, supersize dump trucks used for the transport of agricultural production have much more than 6 tons axle load. Thus, these cars need to have roads with improved surface to each field, which undoubtedly is a significant drawback. Because of the extra movements of harvester dump trucks on the turning strip at the end of the field, it increases expenses of damage and loss of crops and the arrival of heavy machinery in the field leading to soil compaction, that in the end affects the future crop. Transportation of agricultural commodities is most effective when the car arrives directly to the harvester machinery. Such vehicles must have sufficient abilities and capacity of the body comparable with the volume of a combine hopper and has no significant impact on soil sealing. With this method, harvesters do not make extra movements and are not idle. Basic requirements for vehicles used in the harvesting potatoes, are in a more productive use due to increasing the capacity and reducing downtime when loading or unloading and minimizing the level of damage to other tubers. For the transportation of agricultural products there is a different transport technology, which either do not fully meets the requirements of transportation of highly fragile product, or has a significant cost. Therefore, we require a specially equipped vehicle bodies, with a competitive ability in the range acceptable to the Russian Federation. As one of the innovative developments, this article proposes a tipper body of the vehicle for transportation of highly fragile agricultural products. The proposed design solution for the tipper ensures a uniform unloading of transported products from the vehicle body

  10. Ergonomic risks and musculoskeletal disorders in production agriculture: recommendations for effective research to practice.

    Kirkhorn, Steven R; Earle-Richardson, Giulia; Banks, R J

    2010-07-01

    Musculoskeletal disorders (MSDs) are increasingly recognized as a significant hazard of agricultural occupation. In agricultural jobs with significant physical labor, MSDs are typically the most frequently reported injury. Although not as lethal as tractor roll-overs, MSDs can result in disability, lost work time, and increased production costs. MSDs increase production costs as a result of worker absence, medical and insurance costs, decreased work capacity, and loss of employees to turnover and competition from other less physically demanding industries. This paper will provide an overview of what is currently known about MSDs in agriculture, including high-risk commodities, tasks and work practices, and the related regulatory factors and workers' compensation costs. As agricultural production practices evolve, the types of MSDs also change, as do ergonomic risk factors. One example is the previous higher rates of knee and hip arthritis identified in farmers in stanchion dairies evolving into upper extremity tendonitis, arthritis, and carpal tunnel syndrome now found in milking technicians in dairy milking parlors. This paper summarizes the presentation, "Musculoskeletal Disorders in Labor-Intensive Operations," at the Agricultural Safety and Health Council of America/National Institute for Occupational Safety and Health conference, "Be Safe, Be Profitable: Protecting Workers in Agriculture," January 27-28, 2010, Dallas/Fort Worth, Texas. The primary focus of the paper is to address current research on ergonomic solutions for MSDs in agriculture. These include improved tools, carts or equipment, as well as work practices. One of the key challenges in this area pertains to measurement, due to the fact that musculoskeletal strain is a chronic condition that can come and go, with self-reported pain as its only indicator. Alternative measurement methods will be discussed. Finally, the implementation of research into practice is reviewed, with an emphasis on best

    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

  12. Closing the gap: global potential for increasing biofuel production through agricultural intensification

    International Nuclear Information System (INIS)

    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.

  14. Analyses of radionuclides in soil, water, and agriculture products near the Urgeirica uranium mine in Portugal

    International Nuclear Information System (INIS)

    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, 226Ra was the radionuclide more concentrated by vegetables. Through ingestion of these products 226Ra may be the main contributor to the increment of radiation dose received by local population. (author)

    Spatial variability in yields and greenhouse gas emissions from soils has been identified as a key source of variability in life cycle assessments (LCAs) of agricultural products such as cellulosic ethanol. This study aims to conduct an LCA of cellulosic ethanol production from switchgrass in a way that captures this spatial variability and tests results for sensitivity to using spatially averaged results. The Environment Policy Integrated Climate (EPIC) model was used to calculate switchgrass yields, greenhouse gas (GHG) emissions, and nitrogen and phosphorus emissions from crop production in southern Wisconsin and Michigan at the watershed scale. These data were combined with cellulosic ethanol production data via ammonia fiber expansion and dilute acid pretreatment methods and region-specific electricity production data into an LCA model of eight ethanol production scenarios. Standard deviations from the spatial mean yields and soil emissions were used to test the sensitivity of net energy ratio, global warming potential intensity, and eutrophication and acidification potential metrics to spatial variability. Substantial variation in the eutrophication potential was also observed when nitrogen and phosphorus emissions from soils were varied. This work illustrates the need for spatially explicit agricultural production data in the LCA of biofuels and other agricultural products.

  17. Biomass production from the U.S. forest and agriculture sectors in support of a renewable electricity standard

    International Nuclear Information System (INIS)

    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

    Full Text Available In Less Developed Countries (LDCs like Zimbabwe, agricultural production has been regarded by several studies as a paramount prerequisite for industrialization and economic growth. The idea behind this view is that, as agricultural production increases, countries are able to produce more food with less labour input which allows them to feed their growing population while releasing labour for the manufacturing sector and other sectors of the economy hence the process will lead to economic growth. The main objective of this study was to investigate how agricultural production affected economic growth in Zimbabwe from 1980-2010. The Log linear growth regression model was employed where gross domestic product was the dependant variable and the explanatory variables are the major crop products and factors which affect it. Four major crops which were included in the model are tobacco, maize, coffee and cotton. Moreover, a dummy variable for the prevailing weather conditions was also included in the model. The regression analyses were performed using Econometric-views 3 (E-views 3 statistical package. Regression was carried out on time series data for the period 1980 to 2010. The data was tested for stationarity and for autocorrelation. Problems of non stationarity of data were corrected by differencing the trending series. Results from the empirical analysis provide strong evidence indicating that agricultural production is important in improving the wellbeing of countries especially in LDCs. The results from this study suggest that the value of agricultural production of tobacco, maize and cotton positively affects economic growth in Zimbabwe from 1980 to 2010.

    Home courtyard agriculture is an important model of agricultural production on the Tibetan plateau. Because of the sensitive and fragile plateau environment, it needs to have optimal performance characteristics, including high sustainability, low environmental pressure, and high economic benefit. Emergy analysis is a promising tool for evaluation of the environmental-economic performance of these production systems. In this study, emergy analysis was used to evaluate three courtyard agricultural production models: Raising Geese in Corn Fields (RGICF), Conventional Corn Planting (CCP), and Pea-Wheat Rotation (PWR). The results showed that the RGICF model produced greater economic benefits, and had higher sustainability, lower environmental pressure, and higher product safety than the CCP and PWR models. The emergy yield ratio (EYR) and emergy self-support ratio (ESR) of RGICF were 0.66 and 0.11, respectively, lower than those of the CCP production model, and 0.99 and 0.08, respectively, lower than those of the PWR production model. The impact of RGICF (1.45) on the environment was lower than that of CCP (2.26) and PWR (2.46). The emergy sustainable indices (ESIs) of RGICF were 1.07 and 1.02 times higher than those of CCP and PWR, respectively. With regard to the emergy index of product safety (EIPS), RGICF had a higher safety index than those of CCP and PWR. Overall, our results suggest that the RGICF model is advantageous and provides higher environmental benefits than the CCP and PWR systems. PMID:27487808

    2016-02-01

    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.

    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.

    The High Plains Aquifer provides groundwater for 30% of the irrigated agriculture in the USA. Within Kansas, groundwater supports the congressional district with highest market value of agriculture. And yet, over-pumping and associated groundwater declines threaten the long-term prospects. The groundwater portion of this study quantifies the availability of groundwater stores over the next 100 years. A water-use function is developed to quantify the historical and future impacts of irrigation on corn production. A relationship between corn consumption per head of cattle quantifies the herd size that can be supported by irrigated corn. Together, we project the impacts of changes in groundwater stores on corn and cattle production for the next century. Scenarios analyze the impacts of water savings today on current and future agriculture production. Reference: Steward, D. R., Bruss, P. J., Yang, X., Staggenborg, S. A., Welch, S. M. and M. D.

    2016-04-01

    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

    International Nuclear Information System (INIS)

    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

As the object of study we have selected 640 agricultural enterprises of the Krasnodar region for 2013. Cluster analysis allows visually differentiate organizations in economic parameters. The advantage of this approach is evident when analyzed a large number of organizations and performance. It is preferred that clustering is made using hierarchical cluster analysis and k-means. The results of clustering agribusiness enterprises of the Krasnodar region on the main economic indicators were given. During the analysis, we revealed that the AIC enterprises of the Krasnodar region generally form five clusters. Cluster 1 is characterized by a very high level of development of the productive capacity of agribusiness enterprises, consists of 12 organizations and is defined as "extra large" organization. 2nd cluster is characterized as "large", it includes 25 agricultural enterprises. 3rd and 4th clusters - as "average", they account for 60% of the acreage, 52.6% of fixed assets for agricultural purposes. 5th cluster is represented as "small", is a leader in the number of organizations - 371 units and contains a minimum number of employees - 30 people. It is assumed that these approaches can be used for analysis of agricultural organizations of the Krasnodar region with different levels of specialization and in other studies

    1992-01-01

    Until the early 1980s, Mexican economic policy was characterized by import substitution industrialization. Agriculture's role was to provide a cheap and abundant food supply for the urban sector, and to generate foreign exchange through exports. While Mexico achieved food self-sufficiency by the early 1960s, conflicting policies succeeded in undermining basic grain production and exacerbating an existent dichotomy between traditional and rainfed production. Austerity measures imposed during t...

    The production structure of Irish agriculture is analysed empirically via a multiple-input multiple-output translog cost function model. As earlier work in this area was restricted to singleoutput, constant-returns-to-scale models, the current study extends this work by investigating empirically non-constant returns to scale and cost complementarity between products in a multiple-output context, as well as providing hypothesis tests for homotheticity, for constant returns to scale, and for qu...

  1. Potential and impacts of renewable energy production from agricultural biomass in Canada

    International Nuclear Information System (INIS)

    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 CO2 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 CO2 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 generate

    2015-11-01

    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.

    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.

    Full Text Available This study was carried out to ascertain the perception of rural dwellers on human trafficking in relation to its effect on agricultural production in the three Senatorial Districts of Edo State, Nigeria. A sample size of 120 household heads was used for the study. Structured questionnaire and interview schedule were used to collect data for the study. The data were analyzed using frequency counts, means and percentage while Chi-Square statistical model and Tobit regression analytical model were used to test the hypotheses. It was discovered that the household members were trafficked as a result of push and pull factors. The trafficked members of household were actively involved in farming practices before being trafficked. There is significant relationship between human trafficking and agriculture production. Shortage of farm labor, decreased farm size, reduced farm income, reduced farm output, extra expenditure on hired labor and storage of food supply by the community were perceived as effect of human trafficking on agriculture. Age of the household head and the household size had significant effect on the number of household member trafficked. Human trafficking has an adverse effect on agricultural production. Extension department should therefore integrate anti-human trafficking campaigns with their services to the farming population.

    Full Text Available The paper presents the results of the study on the determination and optimization of construction and technology parameters of an electro hydraulic installation developed for research in view of its use in primary processing of agricultural products. Unlike other processing technologies, the proposed technology using electro hydraulic effect requires the application of an installation, which is simple in terms of construction, has low cost, is reliable, easy to use and can be widely applied in various branches of agriculture including primary processing of agricultural products and for sterilizing liquids. The problem of using electro hydraulic effect consists in the correct dimensioning of the installation parameters to obtain high voltage pulses, in comparison with the dimensions of the chamber with electrodes, wherein the liquid processing is carried out. For dimensioning and development of the proposed installation, the necessary parameters were determined by calculation and were confirmed by conducting operational tests. The performed calculation and tests on the operation of the installation under laboratory conditions gave the possibility of dimensioning and optimization of the construction and technological parameters of electro-hydraulic installation, i.e. voltage level, the distance between the electrodes, the volume of the treated liquid, the treatment pulse number and the energy pulsed discharge. The values of the design parameters have allowed to develop and commission the installation, which will allow further tests on use of the electro-hydraulic effect in the processing the agricultural products in the Republic of Moldova.

    conomique sur le continent.Since the end of apartheid, the South African farming sector has been characterized by an unprecedented deregulation process, ending the state paternalism regime of the previous era. The related agricultural liberalization resulted into the engagement of “macro-actors”, including South Africa’s commercial banks, asset management companies and investment funds, as driving force of the sector. These actors gradually strengthened their participation within several agricultural value-chains, particularly in the primary agricultural production segment. New models of agricultural production and financing (eg “pre-crop contract” are presently mushrooming, in which these actors control the totality of the value-chain they’re engaged in. These macro-actors (often non-agricultural, capitalist structures tend to seize control over the agricultural production, considered as speculative commodities hedged on financial markets (Safex in Johannesburg, futures markets in Chicago. If these evolutions question the status of the producers (who become rent-seekers or even employees of the investing institutions and who are not possessing their harvest any more, nor are involved in the decision-making processes, constituting subsequently a new “agricultural proletariat”, they also bring to the fore issues related to food sovereignty and agricultural regulation. These issues are essential considering that in the absence of alternative development models, this conception of agricultural development presently becomes the reference paradigm, in South Africa but also on the continent. It is indeed adopted by public development agencies (NEPAD, AfDB and is exported by these “macro-actors” within the framework of their economic expansion on the African continent.

    Full Text Available In this paper, we present a multi-objective linear fractional programming (MOLFP approach for multi-objective linear fuzzy goal programming (MOLFGP problem. Here, we consider a problem in which a set of pair of goals are optimized in ratio rather than optimizing them individually. In particular, we consider the optimization of profit to cash expenditure and crop production in various seasons to land utilization as a fractional objectives and used remaining goals in its original form. Further, the goals set in agricultural production planning are conflicting in nature; thus we use the concept of conflict and nonconflict between goals for computation of appropriate aspiration level. The method is illustrated on a problem of agricultural production system for comparison with Biswas and Pal [1] method to show its suitability.

    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.

  14. The commercial use of gamma facilities in North and South America for agricultural product processing

    International Nuclear Information System (INIS)

    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)

    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.

    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.

  18. Countermeasures for reduction of radioactive contamination of farm animals and animal products in agricultural ecosystems

    International Nuclear Information System (INIS)

    Contamination of food products reaching the consumer may be a serious problem following radioactive contamination deposited in the agricultural environment. A wide variety of measures is available to reduce or prevent the transfer of radionuclides through the food-chain and hence reduce the radiation dose to the consumer. This paper reviews both literature sources and practice of applying agricultural countermeasures: Interventions at the soil-plant step, at the plant-animal step, and at the foodstuff-man step. In practice, the most effective countermeasures which can be used to reduce radionuclide contamination of animals in agricultural ecosystems will be obtained by a combination of both management changes and the use of chemical binders to prevent gut absorption. Social, economic, and practical considerations of the countermeasures such as availability, technical feasibility, acceptability and side-effects need to be also taken into account. (authors)
