2015-12-01

Full Text Available Agriculture is one of the most important economic activities in each country or area, as it is in close correlation with all other the other economic activities, in a whole which must be structured so as to achieve a more efficient planning and organization of the territory. The practice of a traditional agriculture, based on industrialization, affects the natural environment through emissions of pollutants, waste and deforestation which together affects biodiversity. Green Agriculture suppose to empower managers to widespread the use of fertilizers, to improve the crop rotation, to realize a more efficient water consumption, to improve the storage methods and the supply chain of products. Agricultural policies are closely interrelated with environmental policies as agricultural activities have a considerable influence on the environment. The efficiency of agricultural policies is reflected in monetary transfers between agriculture and other economic sectors, in the costs due to the reallocation of the resources between different agricultural and non-agricultural activities and in the realized gains. Currently there is a constant concern of the governments for the transition to a green agriculture, and most countries recognize the importance of achieving sustainable economic development.

Urban Agriculture: Search for Agricultural Practice in Urbanized Rural Areas

Directory of Open Access Journals (Sweden)

Celile Özçiçek Dölekoğlu

2017-12-01

Full Text Available Rapid urbanization in developing countries involves unplanned migration, unemployment and poverty. The steady shrinking of rural areas and the use of agricultural land for other purposes are progressively increasing the pressure on natural resources. This development on the one hand increases the risk to food security, and on the other triggers climate change. The rural population who migrate to the cities or who are absorbed into urban areas continue their agricultural activities in the urban in order to provide themselves with an income or to maintain their food security. In the big cities of the developed world, contact with nature is kept by means of hobby gardens, recreational areas and urban and suburban plant and animal farming, and creative ideas such as roof gardens can be found. This development, known as urban agriculture, is practiced by 800 million people in the world. Urban agriculture has many economic, social and environmental benefits, but it may also have risks and adverse effects. In this study, the developments in this area in Turkey and the world are presented, and all aspects of its effects and outcomes are discussed.

Researches on Agricultural Cooperative Economic Organization Promoting Agricultural Insurance Development

Institute of Scientific and Technical Information of China (English)

2011-01-01

The advantages of cooperative economic organization being the effective carrier of agricultural insurance development are analyzed. Firstly, cooperative economic organization promotes scale management and solves the problem of decentralized operation of small households. Secondly, cooperative economic organization can settle the problem of peasants’ low systematization. Thirdly, cooperative economic organization can largely reduce the costs of agricultural insurance operation. Fourthly, cooperative organization decreases moral risks as well as adverse selection to some extent. Lastly, cooperative organization, to a certain degree, reduces the risks of agricultural production and increases the insurability of agricultural risks. Meanwhile, limitations of agricultural cooperative economic organization being the carrier of agricultural insurance operation are pointed out. Firstly, cooperative economic organization has limited coverage and small size of organization, which is harmful to the diversification of agricultural risks. Secondly, cooperative economic organization lacks capital funds and its development is not standard, which is not perfect for the function exertion as a carrier. Lastly, members of professional cooperative organization have low cultural qualities, which restrict the implementation of agricultural insurance. The modes of farmers’ cooperative economic organization promoting agricultural insurance development are proposed, including mode of agricultural insurance cooperative ( mutual corporation), mode of "leading enterprises (companies) + professional cooperative organization (planting majors) + insurance" and mode of professional cooperatives serving as agricultural insurance agent. Last of all, the promoting role of agricultural insurance in agricultural cooperative economic organization is briefly illustrated.

PERFORMANCE OF ECOLOGICAL AGRICULTURE IN ROMANIA

Directory of Open Access Journals (Sweden)

CIPRIAN APOSTOL

2014-08-01

Full Text Available The term ecological agriculture has been attributed by the European Union of Romania to define this system of agriculture and is similar with terms organic agriculture or biological agriculture, which are used in other member states. One of the main goals of ecological agriculture is the production of agricultural and food products fresh and genuine through processes created to respect nature and its systems. Thus, it prohibits the use of genetically modified organisms, fertilizers and synthetic pesticides, stimulators and growth regulators, hormones, antibiotics for livestock and the use of synthetic chemical fertilizers, drastic interventions on the soil, the introduction of genetically modified organisms, in the case of the cultivated soil. The study aims to highlight the main features of ecological agriculture and its impact on the national economy. Through a descriptive and comparative analysis of specific indicators are surprising the main aspects of ecological agriculture performance in Romania and are identified investment opportunities in this sector of the national economy. Following this study, it was found that ecological agriculture in Romania is quite performant and recorded a continuous development, but mainly in the production, not in the processing and trading of natural products, which is why investment in these areas would be welcome.

1961-07-15

The Burmese authorities decided to start a laboratory for the use of radioisotope techniques in agricultural r e search. The laboratory was set up at the Agricultural Research Institute at Gyogon, on the outskirts of Rangoon. Under its technical assistance program, IAEA assigned an expert in the agricultural applications of radioisotopes for this project. Discussions were held with regional representatives of the Food and Agriculture Organization on the best lines of research to be adopted at the laboratory in its early stages. As the most important crop in Burma is rice, a series of experiments were planned for a study of the nutrition of rice, particularly its phosphorus uptake, with special reference to comparative responses on a range of typical paddy soils. The experiments began last year and are being continued.

Framing the Future with Bacteriophages in Agriculture.

Science.gov (United States)

Svircev, Antonet; Roach, Dwayne; Castle, Alan

2018-04-25

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

Since the beginning of the 2000s, it has been conducted many projects such as Agricultural Sector Integrated Management Information System, Agriculture Information System, Agricultural Production Registry System and Farmer Registry System by the Turkish Ministry of Food, Agriculture and Livestock and the Turkish Statistical Institute in order to establish and manage better agricultural policy and produce better agricultural statistics in Turkey. Yet, it has not been carried out any study for the structuring of a system which can meet the requirements of different institutions and organizations that need similar agricultural data. It has been tried to meet required data only within the frame of the legal regulations from present systems. Whereas the developments in GIS (Geographical Information Systems) and standardization, and Turkey National GIS enterprise in this context necessitate to meet the demands of organizations that use the similar data commonly and to act in terms of a data model logic. In this study, 38 institutions or organization which produce and use agricultural data were detected, that and thanks to survey and interviews undertaken, their needs were tried to be determined. In this study which is financially supported by TUBITAK, it was worked out relationship between farmer, agricultural land and agricultural production data and all of the institutions and organizations in Turkey and in this context, it was worked upon the best detailed and effective possible data model. In the model design, UML which provides object-oriented design was used. In the data model, for the management of spatial data, sub-parcel data model was used. Thanks to this data model, declared and undeclared areas can be detected spatially, and thus declarations can be associated to sub-parcels. Within this framework, it will be able to developed agricultural policies as a result of acquiring more extensive, accurate, spatially manageable and easily updatable farmer and

Remus Gherman

2016-10-01

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

Financing of permanent working capital in agriculture

Directory of Open Access Journals (Sweden)

Vučković Branko

2017-01-01

Full Text Available In this paper, we attempted to present the problem of establishing adequate structure of financing medium agricultural enterprises and to point out the necessity for permanent working capital in those agricultural enterprises which can’t cover fixed assets, long-term placements and portion of inventories (raw material and spare parts, production in process with own equity and long-term sources of financing. For the purpose of analysing adequate structure of financing medium agricultural enterprises, we will use one of the most popular methods, such as case study and ratio analysis. Results of the research show that in primary agricultural production, next to standard long-term investment loans and short-term loans for investment in agricultural production, there is a necessity for financing in the permanent working capital which could assist continuity of production process and enable conditions for more profitable business in agriculture. It also should be noted that real and book value on this level of permanent working capital differs substantially.

Agricultural Multifunctionality Evolution and Research into Issues concerning Agriculture,Countryside and Farmers

From the point of view of agricultural civilization, the history of human civilization is the history of the development of the agricultural civilization. Accompanied by social progress and development of the times, the function of agriculture also experiences the expansion and deepening. In terms of economy, there is a process from mechanized farming to industrialization, then to informatization, modernization and internationalization. The great rejuvenation of the Chinese nation has also experienced and witnessed this process. In terms of "agriculture, countryside and farmers", the content is complex, diverse, profound, sharp, and changing, constantly testing and challenging our wisdom. When the Document No.1 in 2007 targeted modern agriculture, it indicated that new connotation was integrated into agricultural multifunctionality, standing at a new starting point. At present, the function of agriculture is still deepening; there are tremendous achievements and outstanding problems concurrently in issues concerning agriculture, countryside and farmers. We take the agricultural multifunctionality as breakthrough point for exploration and research.

And on this basis, we analyzed the background and current situation of eco-agriculture of Chinese materia medica, and proposed its development ideas and key tasks, including: (1) Analysis and planning of the production pattern of Chinese material medica national wide. (2) Typical features extraction of regional agriculture of Chinese materia medica. (3) Investigation of the interaction and its mechanism between typical Chinese materia medica in each region and the micro-ecology of rhizosphere soil. (4) Study on technology of eco-agriculture of Chinese materia medica. (5) Extraction and solidification of eco-agriculture modes of Chinese materia medica. (6) Study on the theory of eco-agriculture of Chinese materia medica. Also we pointed out that GAP and eco-agriculture of Chinese material medica are both different and relative, but they are not contradictory with their own features. It is an irresistible trend to promote eco-agriculture in the GAP of Chinese material medica and coordinate ecological and economic development.

Anthropology in Agricultural Health and Safety Research and Intervention.

Science.gov (United States)

Arcury, Thomas

2017-01-01

Agriculture remains a dangerous industry, even as agricultural science and technology continue to advance. Research that goes beyond technological changes to address safety culture and policy are needed to improve health and safety in agriculture. In this commentary, I consider the potential for anthropology to contribute to agricultural health and safety research by addressing three aims: (1) I briefly consider what the articles in this issue of the Journal of Agromedicine say about anthropologists in agricultural health and safety; (2) I discuss what anthropologists can add to agricultural health and safety research; and (3) I examine ways in which anthropologists can participate in agricultural health and safety research. In using their traditions of rigorous field research to understand how those working in agriculture perceive and interpret factors affecting occupational health and safety (their "emic" perspective), and translating this perspective to improve the understanding of occupational health professionals and policy makers (an "etic" perspective), anthropologists can expose myths that limit improvements in agricultural health and safety. Addressing significant questions, working with the most vulnerable agricultural communities, and being outside establishment agriculture provide anthropologists with the opportunity to improve health and safety policy and regulation in agriculture.

Using pesticides has double effects. On one hand, it contributes to pests control and regulates the growth of crops; On the other hand, it does harm to the environment. To develop ecological agriculture should not only emphasize the output level of agriculture to pursuit of economic efficiency, but also need to keep the ecological environment protected and focus on the social benefits during the development of the industry. As a large agricultural country in the world, China is vigorously promoting the development of ecological agriculture, which is bound to put forward to developing the pesticide industry and green ecological development requirements to promote the transformation and upgrading of agricultural pharmaceutical industry. This paper discusses the mechanism of pesticide pollution on the ecological environment and analyzes China's agricultural problems in the pharmaceutical industry. Then study on the development of Chinese green pesticides and try to find the proper paths of agricultural pharmaceutical to achieve industrial upgrading.

Sustainable agriculture: a challenge in Bangladesh

Directory of Open Access Journals (Sweden)

M.A.A. Faroque

2011-12-01

Full Text Available The sustainability of conventional agriculture in Bangladesh is under threat from the continuous degradation of land and water resources, and from declining yields due to indiscriminate use of agro-chemicals. Government is pursuing efforts to promote sustainable agriculture with emphasis on better use of on-farm resources and the reduction of external inputs. This paper presents four dimensions of agricultural sustainability as productivity, environmental stability, economical profitability, and social and economic equity. Six characters were selected to evaluate sustainability. Significant differences were found between the two systems (conventional and sustainable agriculture in crop diversification, soil fertility management, pests and diseases management, use of agro-chemicals and environmental issues. However, no significant variations were found in other indicators such as land-use pattern, crop yield and stability, risk and uncertainties, and food security. Although crop yield and financial return were found to be slightly higher in the conventional system, the economic return and value addition per unit of land did not show any difference. It can be suggested that sustainable agriculture has a tendency towards becoming environmental, economically and socially more sound than conventional agriculture, as it requires considerably less agro-chemicals, adds more organic matter to the soil, provides balanced food, and requires higher local inputs without markedly compromising output and financial benefits. Broad-policy measures, including the creation of mass awareness of adverse health effects of agrochemical-based products, are outlined for the promotion of sustainable agriculture.

An outline is given of the social dilemmas associated with agriculture and horticulture in the Netherlands. Ongoing innovation and accelerated sustainable development are essential to resolve these dilemmas. Given the importance of the Dutch agriculture and horticulture sector, there is every reason for the central government to play its part and help remove the obstacles to the continuing sustainable development of the sector. The Council recommends that the central government continues developing the Council's vision for agriculture and horticulture with the parties concerned, allows scope for the development of different agricultural business models, applies knowledge and innovation as drivers of continuing sustainable development, amends laws and regulations as necessary, and facilitates a permanent dialogue between the sector and society. The advisory report also sets out the Council's vision concerning the political and public debate on agriculture and horticulture. This debate is most clearly characterised by major and seemingly insurmountable differences of opinion. The Council hopes that its report will induce a shift in thinking about Dutch agriculture among politicians and society at large, so that the transitions considered necessary by the Council can be implemented more rapidly.

Continuous Passive Sampling of Solutes from Agricultural Subsurface Drainage Tubes

Science.gov (United States)

Lindblad Vendelboe, Anders; de Jonge, Hubert; Rozemeijer, Joachim; Wollesen de Jonge, Lis

2015-04-01

Agricultural subsurface tube drain systems play an important role in water and solute transport. One study, focusing on lowland agricultural catchments, showed that subsurface tube drainage contributed up to 80% of the annual discharge and 90% of the annual NO3 load from agricultural fields to the receiving water bodies. Knowledge of e.g. nutrient loads and drainage volumes, based on measurements and modelling, are important for adequate water quality management. Despite the importance of tube drain transport of solutes, monitoring data are scarce. This scarcity is a result of the existing monitoring techniques for flow and contaminant load from tube drains being expensive and labor-extensive. The study presented here aimed at developing a cheap, simple, and robust method to monitor solute loads from tube drains. The method is based on the newly developed Flowcap, which can be attached to existing tube drain outlets and can measure total flow, contaminant load and flow-averaged concentrations of solutes in the drainage. The Flowcap builds on the existing Sorbicell principle, a passive sampling system that measures average concentrations over longer periods of time (days to months) for various compounds. The Sorbicell consists of two compartments permeable to water. One compartment contains an adsorbent and one contains a tracer. When water passes through the Sorbicell the compound of interest is absorbed while a tracer is released. Using the tracer loss to calculate the volume of water that has passed the Sorbicell it is possible to calculate the average concentration of the compound. When mounting Sorbicells in the Flowcap, a flow-proportional part of the drainage is sampled from the main stream. To accommodate the wide range of drainage flow rates two Flowcaps with different capacities were tested in the laboratory: one with a capacity of 25 L min-1 (Q25) and one with a capacity of 256 L min-1 (Q256). In addition, Sorbicells with two different hydraulic

The importance of monitoring the quality of vegetables and fruits is prosperity by giving a competitive advantage for producer and providing a more healthy food for consumer. Diffuse Optical Tomography (DOT) is offering the possibility to detect the internal defects of the agricultural produce quality. Fluorescence diffuse optical tomography (FDOT) is the development of DOT, offering the possibilities to improve spatial resolution and to contrast image. The purpose of this research is to compare FDOT and DOT in forward analysis with continuous wave approach. The scattering and absorbing parameters of potatoes are used to represent the real condition. The object was illuminated by the NIR source from some positions on the boundary of object. A set of NIR detector are placed on the peripheral position of the object to measure the intensity of propagated or emitted light. In the simulation, we varied a condition of object then we analyzed the sensitivity of forward problem. The result of this study shows that FDOT has a better sensitivity than DOT and a better potential to monitor internal defects of agricultural produce because of the contrast value between optical and fluorescence properties of agricultural produce normal tissue and defects.

Impact of greenhouse gases on agricultural productivity in Pakistan

International Nuclear Information System (INIS)

Valasai, G.D; Harijan, K.; Uqaili, M.S.; Memon, H.R

2005-01-01

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)

Global climate change and continued intensification of agriculture are two "mega-trends" that will impact agricultural systems in the coming decades. While often these two trends are analyzed in isolation, recent work describes how climate change has historically offset some crop yield gains that would have otherwise occurred. Here we spatially analyze how these interactions between climate change and agricultural development may continue to 2025. We highlight areas that will be hit hardest by climate change and require aggressive management changes, as well as areas where large productivity increases are likely given current trends. To carry out our analysis we rely on a recently developed climate analog model to produce projections of climate-induced yield changes, projections of business-as-usual crop yield trends utilizing time-series data from ~13,500 agricultural census units, and published estimates of possible crop yield increases from aggressive intervention to close yield gaps. We find that a rich picture of agriculture in 2025 emerges when analyzing these multiple critical drivers. In many regions, existing yield trends or more aggressive management interventions (closing yield gaps) can overcome negative impacts from climate change. Thus, intensification can provide a buffer from near-term climate impacts, but it is unclear how long society may be able to rely on this buffering capacity.

Climate change and agriculture in Denmark

International Nuclear Information System (INIS)

Olesen, J.E.

2001-01-01

This chapter reviews the current knowledge on effects of climate change on agriculture in Denmark, and the contribution of agriculture to greenhouse gas emissions in Denmark. The chapter also considers the possibilities of Danish agriculture to adapt to changing climate and to reduce greenhouse gas emissions. The relations to other aspects of global change are discussed, including liberalisation of world markets and changes in land use. Scenarios of climate change for Denmark suggest increases in annual mean temperature of 1 to 4 deg. C by the end of the 21st century depending on socioeconomic development. Winter rainfall may increase up to 20%. This implies a wide range of possible consequences. Agricultural productivity may be expected to increase under increasing temperature and increasing CO 2 concentration. Highter temperatures will increase the risk of pests and deseases. Warming in association with increased winter rainfall will also increase the risk of nitrate leaching. Climate change may thus be expected to reinforce the current trends in Danish agriculture of declining cattle population and increasing pig and cereal production. Apart from an anticipated continued decline in total agricultural area, land use will probably not be greatly affected. The current environmental regulation in Denmark aims at reducing pesticide use and nitrogen losses from agriculture. Some of the regulations are very detailed and directly regulate farming practices in a manner that may not provide the most cost-effective mechanism under a changed climate. Some of these existing rigid frameworks for environmental regulation should thus be substituted by more flexible goal-oriented environmental protection strategies, in order to ensure sustainability of farming under global climate change.

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

Introduction to the JEEG Agricultural Geophysics Special Issue

Science.gov (United States)

Allred, Barry J.; Smith, Bruce D.

2010-01-01

Near-surface geophysical methods have become increasingly important tools in applied agricultural practices and studies. The great advantage of geophysical methods is their potential rapidity, low cost, and spatial continuity when compared to more traditional methods of assessing agricultural land, such as sample collection and laboratory analysis. Agricultural geophysics investigations commonly focus on obtaining information within the soil profile, which generally does not extend much beyond 2 meters beneath the ground surface. Although the depth of interest oftentimes is rather shallow, the area covered by an agricultural geophysics survey can vary widely in scale, from experimental plots (10 s to 100 s of square meters), to farm fields (10 s to 100 s of hectares), up to the size of watersheds (10 s to 100 s of square kilometers). To date, three predominant methods—resistivity, electromagnetic induction (EMI), and ground-penetrating radar (GPR)—have been used to obtain surface-based geophysical measurements within agricultural settings. However, a recent conference on agricultural geophysics (Bouyoucos Conference on Agricultural Geophysics, September 8–10, 2009, Albuquerque, New Mexico; www.ag-geophysics.org) illustrated that other geophysical methods are being applied or developed. These include airborne electromagnetic induction, magnetometry, seismic, and self-potential methods. Agricultural geophysical studies are also being linked to ground water studies that utilize deeper penetrating geophysical methods than normally used.

The Role Played by Agricultural Policy-based Finance in New Village Construction

Institute of Scientific and Technical Information of China (English)

2011-01-01

The necessity of the agricultural policy-based finance in terms of supporting the new village construction is analyzed: in the first place, the theoretical roots of agricultural policy-based finance supporting new village construction are "market failure" and "government intervention"; in the second place, the continual decline of agriculture and the "rural financial market failure" in recent years have become the objective evidence and historical mission for agricultural policy-based finance to support new village construction; in the third place, the combination of agricultural policy-based finance and new village construction is conducive to solving the "three agriculture" problems and facilitating the reform of new village construction. The feasibility of the support is analyzed: firstly, agricultural policy-based finance boasts the status and position of the "primary drive" in new village construction; secondly, the nation continuously deepens the reform of rural financial system and policy-based banks and strengthens the functions of Agricultural Development Bank, which provides policies for agricultural policy-based finance to support new village construction; thirdly, the 14 years’ reform and development of Agricultural Development Bank and the eleventh five year plan lay sound practical basis for the support of agricultural policy-based finance to new village construction. Based on the necessity and feasibility, the following six aspects are analyzed to fully display the function of the "first engine" of agricultural policy-related finance to new village construction. Firstly, strengthening the credit and loan aid to grain and cotton and some other agricultural products in the circulation domain; secondly, strengthening the credit and loan aid to agricultural industrialization in processing field; thirdly, intensifying the credit and loan aid to agricultural comprehensive development, rural infrastructure construction, application and promotion of

Clustering of agricultural enterprises

Michaela Beranová

2013-01-01

Full Text Available Agricultural business is a very specific branch which is characterized by very low financial performance while this characteristic is given mainly by external factors as market pricing of agricultural commodities on one side, and production costs of agricultural commodities on the other side. This way, agricultural enterprises recognize negative values of gross margin in the Profit and Loss Statement but positive value of operating profit after even there are items of costs which are deducted. These results are derived from agricultural production subsidies which are recognized as income in the P/L Statement. In connection with this fact, the government subsidies are a substantial component of financial performance of agricultural enterprises.Primary research proceeded on the statistical sample of one hundred agricultural companies, has shown that also other specifics influencing financial performance of these businesses exist here. In order to determine the influences, the cluster analysis has been applied at using more than 10 variables. This approach has led to construction of clusters (groups of agricultural business entities with different characteristics of the group. The objective of this paper is to identify the main determinants of financial performance of agricultural enterprises and to determine their influences under different economic characteristics of these business entities. For this purpose, the regression analysis has been subsequently applied on the groups of companies coming out from the cluster analysis. Besides the operating profit which is the main driving force of financial performance measured with the economic value added (EVA in agricultural enterprises, also capital structure and cost of capital have been observed as very strong influences on financial performance but these factors have different directions of their influence on the economic value added under different financial characteristics of agricultural

This paper presents and comments the main results of a work-group focused on the evolution of agriculture in France in relationship with the new energetic context. Four scenarios have been defined, corresponding to different energetic, but also social, political and economic contexts by 2030. The first one corresponds to a severe energy crisis with an emergence of regional governance. The second one corresponds to a high volatility of energy prices, an increased easing of restrictions on trade, and a decrease of public supports and subsidies for agriculture. The third one corresponds to a strong reduction of the use of phyto-sanitary products in agriculture, a continuous urban sprawl, and the prevalence of road transport. The fourth one corresponds to agriculture respectful of the environment and a good management of energy consumption. Direct and indirect energy consumptions are assessed for the four scenarios. Some general and operational objectives are thus identified

Economic Drought Impact on Agriculture: analysis of all agricultural sectors affected

Gil, M.; Garrido, A.; Hernández-Mora, N.

2012-04-01

The analysis of drought impacts is essential to define efficient and sustainable management and mitigation. In this paper we present a detailed analysis of the impacts of the 2004-2008 drought in the agricultural sector in the Ebro river basin (Spain). An econometric model is applied in order to determine the magnitude of the economic loss attributable to water scarcity. Both the direct impacts of drought on agricultural productivity and the indirect impacts of drought on agricultural employment and agroindustry in the Ebro basin are evaluated. The econometric model measures losses in the economic value of irrigated and rainfed agricultural production, of agricultural employment and of Gross Value Added both from the agricultural sector and the agro-industrial sector. The explanatory variables include an index of water availability (reservoir storage levels for irrigated agriculture and accumulated rainfall for rainfed agriculture), a price index representative of the mix of crops grown in each region, and a time variable. The model allows for differentiating the impacts due to water scarcity from other sources of economic losses. Results show how the impacts diminish as we approach the macro-economic indicators from those directly dependent on water abstractions and precipitation. Sectors directly dependent on water are the most affected with identifiable economic losses resulting from the lack of water. From the management perspective implications of these findings are key to develop mitigation measures to reduce drought risk exposure. These results suggest that more open agricultural markets, and wider and more flexible procurement strategies of the agro-industry reduces the socio-economic exposure to drought cycles. This paper presents the results of research conducted under PREEMPT project (Policy relevant assessment of the socioeconomic effects of droughts and floods, ECHO - grant agreement # 070401/2010/579119/SUB/C4), which constitutes an effort to provide

The present overview document contains the main results of the Agriculture Energy 2030 prospective study, based on the work of the group led by the CEP [Centre d'etudes et de prospective/Centre for studies and strategic foresight] at the Ministry of Agriculture, Food, Fisheries, Rural Affairs and Spatial Planning. Energy in agriculture is all too often seen as a purely cyclical problem whereas it is a major issue for the future due to its economic consequences for agricultural holdings, its links with environmental and climatic issues, and its influence on food supply chains and spatial planning. Based on the scenario method, this analysis initially involved describing the whole range of links between agriculture and energy in France and organising them into a system of variables before going on to draw up an inventory of the knowledge available. Starting out from this diagnostic approach, the group constructed four scenarios over the period to 2030: 'Regionalization and sobriety to confront the crisis', 'Twin track agriculture and energy realism', 'Health Agriculture with no major energy constraints' and 'Ecological agriculture and energy savings'. These scenarios do not form an exhaustive panorama of all possible developments of the agriculture-energy system - they are rather formalised images of what the future might hold. However, quantification and comparison of the scenarios has led to the identification of major room for progress in energy efficiency in French farming. By helping gain greater awareness of future difficulties and issues or, conversely, opportunities to be grasped, these scenarios provided input for the strategic analysis phase, the concluding stage of this exercise, and the identification of general objectives and levers for public action.

Agricultural productivity to meet growing demands of human population is a matter of great concern for all countries. Use of green compounds to achieve the sustainable agriculture is the present necessity. This review highlights the enormous use of harsh surfactants in agricultural soil and agrochemical industries. Biosurfactants which are reported to be produced by bacteria, yeasts, and fungi can serve as green surfactants. Biosurfactants are considered to be less toxic and eco-friendly and thus several types of biosurfactants have the potential to be commercially produced for extensive applications in pharmaceutical, cosmetics, and food industries. The biosurfactants synthesized by environmental isolates also has promising role in the agricultural industry. Many rhizosphere and plant associated microbes produce biosurfactant; these biomolecules play vital role in motility, signaling, and biofilm formation, indicating that biosurfactant governs plant-microbe interaction. In agriculture, biosurfactants can be used for plant pathogen elimination and for increasing the bioavailability of nutrient for beneficial plant associated microbes. Biosurfactants can widely be applied for improving the agricultural soil quality by soil remediation. These biomolecules can replace the harsh surfactant presently being used in million dollar pesticide industries. Thus, exploring biosurfactants from environmental isolates for investigating their potential role in plant growth promotion and other related agricultural applications warrants details research. Conventional methods are followed for screening the microbial population for production of biosurfactant. However, molecular methods are fewer in reaching biosurfactants from diverse microbial population and there is need to explore novel biosurfactant from uncultured microbes in soil biosphere by using advanced methodologies like functional metagenomics.

Eva Vávrová

2010-01-01

Full Text Available Proactive approach to risk management of agriculture companies is the way to ensure the efficiency of agricultural production even affected by natural disasters, to ensure the continuity of agricultural business and ultimately affect the level of development of rural regions. The instrument that solves the problem of reduction and elimination of risks associated with agricultural production is a systemic approach to the insurance of agricultural production, both crop insurance and livestock insurance, linked to a support program for SME in agriculture.This presented paper aims to identify and discuss the possibility of eliminating risks possibly threate­ning the agricultural production and to analyze forms of covering risks associated with agricultural production on the commercial insurance market in the Czech Republic. The paper analyzes the current situation and current development of the agricultural insurance on the insurance market in the Czech Republic.This paper was written as a part of the research project MSM 6215648904, carried out by the Faculty of Business and Economics, under the title „The Czech economics in the processes of integration and globalization, and the development of the agriculture and service sector in the new conditions of the integrated European market“, following the goals and methodology of the research project.

HISTORICAL DEVELOPMENT OF AGRICULTURAL ACCOUNTING AND DIFFICULTIES ENCOUNTERED IN THE IMPLEMENTATION OF AGRICULTURAL ACCOUNTING*

Directory of Open Access Journals (Sweden)

Zeki Doğan

2013-10-01

Full Text Available Agricultural sector, from past to present, had assumed very important duties on economic and social development of societies. It became a globally indispensable and strategic sector due to its various attributes such as: direct/indirect contributions to population nourishment, national income, employment, capital transfers, raw material supply for industry, exportation, biological diversity and ecological balance. Since the dawn of humankind, agricultural sector had gone through a variety of phases in terms of production activities and land proprietorship. Agricultural activities that emerged in the period of hunter-gatherer societies have been superseded by today’s specialized and planned agricultural enterprises utilizing information and technology. Agricultural accounting has also experienced a significant change in parallel with those improvements. This study aims to investigate historical development of agricultural accounting and difficulties encountered during its implementation. Research studies indicate that agricultural assets were initially recorded and inventory controls were performed by Sumerians. Until the Middle Ages, agricultural accounting did not experience any development, whereas it still encounters various difficulties eve

Agriculture in an industrial framework

Directory of Open Access Journals (Sweden)

Edgar Thomas

1966-12-01

Full Text Available The present shape of agriculture in every country is the result of a complex of past economic, social and political factors. These factors are continuously under pressure from new forces. Today, for better or for worse, the pursuit of economic growth has become the dominant force the world over. In order to achieve and sustain a more rapid rate of growth two things are necessary. The first is to improve productivity within each activity by the greater application of capital, by better technology, by better management and by better organisation. The second is to aim at the optimum allocation of resources between activities by moving resources from less to more productive uses. Pursuing these two paths towards faster growth is releasing two sets of forces which are exerting a radical impact on both the size and the pattern of agriculture. This paper deals with this impact on agriculture in contemporary Britain a highly industrial and a preponderantly urban nation committed to the experiment of running a hybrid economy based on the two pillars of private enterprise and public control.

Sources of innovation in agricultural technology

Energy Technology Data Exchange (ETDEWEB)

Biggs, S D; Clay, E J

1981-04-01

This paper focuses attention on environmental and biological characteristics of agriculture which shape the process of technical innovation. The interaction of natural selection and human purposive selection and experimentation is shown to result in a continuous process of innovation placing farmers in the informal R and D systems as well as scientists in formal R and D systems in an innovative treadmill. The importance and limitations of informal R and D are reviewed. A discussion of the characteristics and potential of formal R and D systems leads to the identification of some major problems of policy inherent in, and specific to, the organization and management of agricultural research resources. These include: genetic vulnerability, choices between environmentally specific or widely adapted technologies, the location of research activity, the linkages between agricultural producers and scientists, and methods for maintaining and strengthening informal R and D systems. 58 references, 2 figures.

Agricultural franchising and contribution to achieving objectives of the EU common agricultural policy

Directory of Open Access Journals (Sweden)

Stanković Milica

2014-01-01

Full Text Available The Common Agricultural Policy is the oldest, the most complex, the most expensive EU policy and it represents one of the most important drivers of European integration. Agrarian franchising is one of the innovations in the field of franchising, which implementation is still in its infancy and it is necessary to strive for the popularization of this business model. The aim of the paper is to emphasize the importance of agricultural franchising concept development and contribution of implementation of this concept to the achievement of the Common Agricultural Policy objectives and improvement of the agrarian sector as a whole. Special attention is paid on agricultural franchising as a hybrid form of disinvestment in conditions of economic crisis. Based on analysis of advantages and disadvantages of agricultural franchising, we conclude that it has the potential for solving a large number of problems that occur in the agrarian sector, with a particular focus on the importance of agricultural franchising to the achievement of the CAP objectives.

Sustainable Agricultural Marketing Initiatives

Directory of Open Access Journals (Sweden)

Hakan Adanacıoğlu

2015-07-01

Full Text Available Sustainable marketing is a holistic approach that puts equal emphasis on environmental, social equity, and economic concerns in the development of marketing strategies. The purpose of the study is to examine and discuss the sustainable agricultural marketing initiatives practiced throughout the World and Turkey, and to put forth suggestions to further improve the performance of agricultural marketing initiatives in Turkey. Some of the sustainable agricultural marketing initiatives practiced around the world are carried out through civil organizations. Furthermore; some of these initiatives have also launched by farmers, consumers, food processors and retailers. The long-term strategies to increase these initiatives should be determined due to the fact that examples of successful sustainable agricultural marketing initiatives are inadequate and cannot be spread in Turkey. In this context, first of all, the supports provided by the government to improve agricultural marketing systems, such as EU funds for rural development should be compatible with the goals of sustainable marketing. For this purpose, it should be examined whether all proposed projects related to agricultural marketing meet the social, economic, and environmental principles of sustainable marketing. It is important that supporting organizations, especially civil society organisations, should take an active role for faster dissemination and adoption of sustainable agricultural marketing practices in Turkey. These organizations may provide technical assistance in preparing successful project proposals and training to farm groups. In addition, the other organizations, such as local administrations, producers' associations, cooperatives, can contribute to the success of sustainable agricultural marketing initiatives. The use of direct marketing strategies and vertical integration attempts in sustainable agricultural marketing initiatives that will likely be implemented in Turkey is

Hartley, Sarah; Gillund, Frøydis; van Hove, Lilian; Wickson, Fern

2016-05-01

Agricultural biotechnology continues to generate considerable controversy. We argue that to address this controversy, serious changes to governance are needed. The new wave of genomic tools and products (e.g., CRISPR, gene drives, RNAi, synthetic biology, and genetically modified [GM] insects and fish), provide a particularly useful opportunity to reflect on and revise agricultural biotechnology governance. In response, we present five essential features to advance more socially responsible forms of governance. In presenting these, we hope to stimulate further debate and action towards improved forms of governance, particularly as these new genomic tools and products continue to emerge.

Full Text Available Decision-making in agriculture has tended to be driven by factors other than environmental concerns. This may be changing, and perhaps the emphases of the two creation accounts in Genesis (responsible management or 'dominion', and active care may become more important. The paper examines a number of current developments in agriculture (synthetic fertilizers and pesticides, genetic manipulation, and organic versus industrial methodologies and discusses the issues they raise for agricultural productivity and the human communities dependent on farming. The questions raised are complex; we are faced with establishing a new paradigm for agricultural practice.

Since its beginnings, the Agricultural Area had a selected research team involved in the development of different agricultural techniques. Currently, there are two main branches engaged in the solution of agricultural problems: Soil fertility and induced mutations. Soil fertility: Within this branch, studies on soil nutrients and availability of water and light resources, have been made by using isotope methods. In the near future studies on nitrogen and potassium content in potato, rice and wheat plantations will be held. Induced mutations: The main objective of this team is to obtain through radioinduced mutations, as well as in vitro growth, improved rice and other cereal seeds to be used under hostile environmental conditions. The further goal will be to develop new genotypes straight from the mutants or by utilization of this material as breeding materials in interchange programs

Food and Agriculture Policy in Europe.

Birt, Christopher A

2016-01-01

Diet includes many risk factors for the most common non-communicable diseases (NCDs), but diets consumed in Europe and in other parts of the developed world are not being modified sufficiently to take account of health priorities concerning, in particular, the prevention of NCDs, while much excess mortality and morbidity could be prevented by government actions to regulate appropriately both the agricultural and food industries, and to apply appropriate taxes and subsidies to promote healthier nutrition. In Europe, the Common Agricultural Policy (CAP) continues to promote production of saturated fat rich foods and sugar, with scarce attempts to promote increased production of fruit and vegetables. Meanwhile, the food industry continues to market secondary food products rich in sugar, salt and saturated fats. Powerful lobbies seek to block reform; however, necessary reforms are indicated in the interests of improved nutritional health.

Full Text Available Technical efficiency of agricultural resources use in Russia is assessed. As methodology for calculations the author used Data envelopment analysis (DEA which is the nonparametric method based on linear programming. The essence of the DEA method consists in an efficiency evaluation of homogeneous units of decision making proceeding from creation on the basis of real data (amounts of resources and amounts of types of output of general border of production capabilities. CCR-I model was offerd as a specific kind of the DEA model. It is the radial DEA model with continual returns to scale and orientation to resources. The group of 54 countries included in a research consisted of the states of the CIS, BRIC, the EU, OECD. The time frames of calculation were established: 1992-2007 and 2008-2012 (owing to lack of uniform data for all time interval. Аmount of agricultural products was used as output. Agricultural lands, an economically active population in agriculture, farm machines and the equipment, a livestock, fertilizers were used in the form of resources. The main source of statistical data is FAOSTAT. From 54 countries under consideration Belgium, Greece, Israel, Malta and the Netherlands became leaders in technical efficiency of agricultural industry in 1992-2007. Inefficient use of agricultural resources, especially lands was established as a result of the conducted research in Russia. On average efficiency of use of agricultural lands in our country can be increased by 8 times, work - by 2-2.5 times, machines - by 2-3 times, a livestock and fertilizers - by 1.5-2 times. Good tendencies to growth of efficiency of agricultural production are notice in 2008-2012.

2017-08-01

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

“Increased women’s enrollment in agricultural courses” as one among the strategies when addressing gender issues in the education and training components of agricultural development projects. In this context the study was carried out to ascertain the representation of women and their academic achievement in agricultural education. The study revealed that almost equal representation was found for women in agricultural course and they were also provided better quality education in their schooling, in the form of English medium education and education in private schools. Recent trends for the past four years showed a higher percentage of enrollments of women in agricultural course than men. The growth rate was also higher for the female students. Women also showed a significantly higher percentage of academic achievement than men. These positive indicators provide sufficient signals for equality of women in agricultural course and have positive implications for development of the agricultural sector in future.

Environmental assessment of Swedish agriculture

Engstroem, Rebecka; Finnveden, Goeran; Wadeskog, Anders

2007-01-01

This article describes an environmental assessment of Swedish agriculture, including upstream and downstream effects. The analysis is based on environmentally extended input-output analysis, but it is also supplemented with data from other sources. The analysis shows that direct effects by the Swedish agriculture are the most important, while indirect effects from other sources including mobile and impacts abroad are also considerable. The most important impacts from Swedish agriculture according to the analysis are eutrophication, global warming and resource use. The agricultural sector produces a large share of the Swedish emissions causing both global warming and eutrophication. In addition, current agricultural practice causes problems with loss of biodiversity. The most important actors in the sector are agriculture itself, but also all actors using fossil fuels: primarily the transport sector and the energy sector. In addition, consumers are important since they can influence the composition of agricultural production. The analysis shows the importance of including upstream and downstream effects when analysing the environmental impacts from a sector. (author)

Fukugawa, Nobuya

2017-12-01

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

Water Resources and Sustainable Agriculture in 21st Century: Challenges and Opportunities

Asrar, G.

2008-05-01

Global agriculture faces some unique challenges and opportunities for the rest of this century. The need for food, feed and fiber will continues to grow as the world population continue to increase in the future. Agricultural ecosystems are also expected to be the source of a significant portion of renewable energy and fuels around the world, without further compromising the integrity of the natural resources base. How can agriculture continue to provide these services to meet the growing needs of world population while sustaining the integrity of agricultural ecosystems and natural resources, the very foundation it depends on? In the last century, scientific discoveries and technological innovations in agriculture resulted in significant increase in food, feed and fiber production globally, while the total amount of water, energy, fertilizers and other input used to achieve this growth remained the same or even decreased significantly in some parts of the world. Scientific and technical advances in understanding global and regional water and energy cycles, water resources management, soil and water conservation practices, weather prediction, plant breeding and biotechnology, and information and communication technologies contributed to this tremendous achievement. The projected increase in global population, urbanization, and changing lifestyles will continue the pressure on both agriculture and other managed and natural ecosystems to provide necessary goods and services for the rest of this century. To meet these challenges, we must obtain the requisite scientific and technical advances in the functioning of Earth's water, energy, carbon and biogeochemical cycles. We also need to apply the knowledge we gain and technologies we develop in assessing Earth's ecosystems' conditions, and their management and stewardship. In agricultural ecosystems, management of soil and water quality and quantity together with development of new varieties of plants based on advances

Shusen Gui

2012-12-01

Full Text Available As agricultural mechanization accelerates the development of agriculture in China, to control the growth of the resulting energy consumption of mechanized agriculture without negatively affecting economic development has become a major challenge. A systematic analysis of the factors (total power, unit diesel consumption, etc. influencing diesel consumption using the SECA model, combined with simulations on agricultural diesel flows in China between 1996 and 2010 is performed in this work. Seven agricultural subsectors, fifteen categories of agricultural machinery and five farm operations are considered. The results show that farming and transportation are the two largest diesel consumers, accounting for 86.23% of the total diesel consumption in agriculture in 2010. Technological progress has led to a decrease in the unit diesel consumption and an increase in the unit productivity of all machinery, and there is still much potential for future progress. Additionally, the annual average working hours have decreased rapidly for most agricultural machinery, thereby influencing the development of mechanized agriculture.

In Lebanon, emissions of greenhouse gases from agricultural activities occur through the following processes: -enteric fermentation and manure management of the domestic livestock emits methane and nitrous oxide. -agricultural burning of crop residues is of minor importance since field burning of crop residue is not a common practice in Lebanon -agricultural soils are a source of nitrous oxide directly from the soils and from animal production, and indirectly from the nitrogen added to the soils. The following results were obtained for the inventory year 1994: 7.60955 Gg of methane, 3.01478 Gg of nitrous oxide, 0.00146 Gg of nitrogen oxides and 0.04306 Gg of carbon monoxide

Agriculture and malnutrition in India.

2012-03-01

Despite the high and relatively stable overall growth of the economy, India's agriculture sector is underperforming and a vast section of the population remains undernourished. To explore the possible interplay between agricultural performance and malnutrition indicators to see whether states that perform better in agriculture record better nutritional outcomes. Correlation analysis and a simple linear regression model were used to study the relationship between agricultural performance and malnutrition among children under 5 years of age and adults from 15 to 49 years of age at 20 major states using data from the National Family Health Survey-3 for the year 2005/06 and the national accounts. Indicators of the level of agricultural performance or income have a strong and significant negative relationship with indices of undernutrition among adults and children, a result suggesting that improvement of agricultural productivity can be a powerful tool to reduce undernutrition across the vast majority of the population. In addition to agriculture, access to sanitation facilities and women's literacy were also found to be strong factors affecting malnutrition. Access to healthcare for women and child-care practices, in particular breastfeeding within 1 hour after birth, are other important determinants of malnutrition among adults and children. Malnutrition is a multidimensional problem that requires multisectoral interventions. The findings show that improving agricultural performance can have a positive impact on nutritional outcomes. However, improvements in agriculture alone cannot be effective in combating malnutrition if several other mediating factors are not in place. Interventions to improve education, health, sanitation and household infrastructure, and care and feeding practices are critical. Innovative strategies that integrate agriculture and nutrition programs stand a better chance of combating the malnutrition problem.

The use of GMOs (genetically modified organisms): agricultural biotechnology or agricultural biopolitics?

Science.gov (United States)

Nuti, Marco; Felici, Cristiana; Agnolucci, Monica

2007-01-01

Agricultural biotechnologies embrace a large array of conventional and modern technologies, spanning from composting organic by-products of agriculture to innovative improvement of quality traits of about twenty out of the mostly cultivated plants. In EU a rather restrictive legislative framework has been installed for GMOs, requiring a risk assessment disproportionate with respect to conventional agriculture and organic farming products. The latter are far from being proved safe for human and animal health, and for the environment. Biotechnology of GMOs has been overtaken by biopolitics. On one side there are biotechnological challenges to be tackled, on another side there is plenty of ground for biopolitical decisions about GMOs. Perhaps the era of harsh confrontation could be fruitfully replaced by sensible cooperation, in order to get a sustainable agricultural development.

Marcelo Boamorte Ravelli

Full Text Available ABSTRACT: The great challenge for the practice of agricultural aviation has been to avoid accidents. Although, there are technological progress and high resources for safety, accidents continue to occur. The objective of this research was to analyze the influence and occurrence of factors in agricultural aviation accidents in Brazil recently. Based on research and technical - scientific papers written by researchers and aviation authorities, recommendations directed towards reducing the risks associated with this aircraft modality are assessed. The main factors responsible for accidents are normally operational errors and maneuvers that cause flight collisions, engine failures and altitude loss. Professional awareness and qualification converge towards the success of the agricultural pilot in the detection of inherent dangers or occasional in the various systems involved.

The development and adaption of early agriculture in Huanghe River Valley, China

Science.gov (United States)

Li, X.

2017-12-01

The expanding and developing of agriculture are the basic of population growth, the expansions of material cultures and civilization. The Huanghe River valley, as the origin center of millet agriculture, lies between the heartlands of wheat and rice, which gestates the flourishing Neolithic culture based on agriculture. Recent work using botanical remains has greatly expanded the knowledge concerning early agriculture. Here, we report the new progress on the development and adaption of early agriculture in Huanghe River valley and the surrounding areas. Based on the analysis of phytolith from 13 sites in middle reaches of Huanghe River and the survey of crop seeds from 5 sites in Guanzhong Basin, the rice have been cultivated around 7600 cal BP in semi-humid regions dominated by rain-fed agriculture. The mixed agriculture of common millet, foxtail millet, and rice continued to exist between 7600-3500 BP. In semi-arid region of Huanghe River valley, the agriculture was dominated by the production of common and foxtail millet and 3 major changes have taken place around 6500 BP, 5500 BP, and 4000 BP during Neolithic. The cultivating ratio of common and foxtail millet was adjusted by farmer for adapting the climate changes during Holocene. Approximately 5000 yr BP, the rain-fed agriculture continues to break geographical boundaries to expand to west and southwest from Huanghe River valley. Millet agriculture appeared in southern Ganshu and north eastern Tibetan Plateau. The common and foxtail millet spread to the arid-area of Hexi corridor, a major crossroad of the famous Silk Road, around 4500 yr BP. Wheat was added as a new crop to the existing millet based agricultural systems around 4100-4000 cal yr BP in Hexi corridor. Between 3800 and 3400 cal yr BP, the proportion of wheat and barley in agriculture was up to 90%,which have replaced the local millet and become the main crops. And now, some new evidences of wheat agriculture from NW Xijiang have been obtained and

Agricultural transportation fuels

International Nuclear Information System (INIS)

Anon.

1993-01-01

The recommendations on the title subject are focused on the question whether advantages and disadvantages of agricultural fuels compared to fossil fuels justify the Dutch policy promotion of the use of agricultural products as basic materials for agricultural fuels. Attention is paid to energetic, environmental and economical aspects of both fuel types. Four options to apply agricultural transportation fuels are discussed: (1) 10% bio-ethanol in euro-unleaded gasoline for engines of passenger cars, equipped with a three-way catalyst; (2) the substitution of 15% methyl tertiair butyl ether (MTBE) by ethyl tertiair butyl ether (ETBE) as a substituent for lead in unleaded super plus gasoline (Sp 98) for engines of passenger cars, equipped with a three-way catalyst; (3) 50% KME (rapeseed oil ester) in low-sulfur diesel (0.05%S D) for engines of vans without a catalyst; and (4) the substitution of 0.05% S D by bio-ethanol or KME for buses with fuel-adjusted engines, equipped with a catalyst. Also the substitution by liquefied petroleum gas (LPG), compressed natural gas (CNG) or E 95 was investigated in option four. Each of the options investigated can contribute to a reduction of the use of fossil energy and the environmental effects of the use of fossil fuels, although some environmental effects from agricultural fuels must be taken into consideration. It is recommended to seriously pay attention to the promotion of agricultural fuels, not only in the Netherlands, but also in an international context. Policy instruments to be used in the stimulation of the use of such fuels are the existing European Community subsidies on fallow lands, exemption of the European Community energy levy, and the use of tax differentiation. Large-scale demonstration projects must be started to quantify hazardous emissions and to solve still existing technical problems. 8 figs., 3 tabs., refs., 4 appendices

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

Full Text Available The article is focused on the consideration between the agricultural land acreage and the amount of land tax in the selected sample of companies of agricultural primary production in the Slovak Republic within the period from 2010 to 2014 based on the data from departmental database of enterprises with primary agricultural production drawn from the factsheets of Ministry of Agriculture and Rural Development of the Slovak Republic presented by the selected statistical methods. In particular, the article presents the agricultural land and land tax from the accounting and tax perspective of the Slovak Republic and the European Union. It can be resulted that a slightly declining trend of the mean acreage of agricultural land was recorded for the evaluated group of agricultural enterprises within the reported period, while the mean land tax value per hectare of agricultural land had increasing trend. Results of the survey on significances of differences in the values of the dependent variables at the level of combinations of factors of year and enterprise indicate that the acreage of agricultural land and the volume of the land tax are statistically dependant at the level of year, however there are not dependent at the level of combination of factors of year and enterprise within the surveyed period.

2008-10-01

Full Text Available In the present global situation, agriculture plays a major role in the interaction between socio-economic and biophysical processes. In addition to its principal and fundamental role of providing food, it now also needs to consider other ecosystem services provided by agriculture and to explore the new frontiers for the the future. In the 50’s of the 20th century the major topic was the introduction of inorganic fertilizers, in the 60’s the use of synthetic compounds for plant protection (insecticides, herbicides, fungicides, in the 70’s industrial crops, in the 80’s organic farming and the environmental impact of agronomic practices, and in the 90’s genetically modified crops (herbicide tolerance, insect resistance. In the current decade the themes are: land and water degradation, the production of agricultural biomass for bio-energy, and the increased expression of functional compounds in crops. The Bologna X Congress of ESA “Multi-functional Agriculture - Agriculture as a Resource for Energy and Environmental Preservation”, will meet the needs of finding tools to deal with environmental problems coupled with the increasing demand for food, and filling the knowledge gap on the physiological relationships between functional compound bio-synthesis and agricultural practices. Members of the European Society for Agronomy already have a deep knowledge of these issues, and the Bologna ESA Congress will provide an opportunity to develop them further particularly in regard to innovative agricultural techniques, new energy sources and better environmental monitoring.

Agriculture energy prospective by 2030: scenarios and action patterns

International Nuclear Information System (INIS)

2010-01-01

This paper presents and comments the main results of a work-group focused on the evolution of agriculture in France in relationship with the new energetic context. Four scenarios have been defined, corresponding to different energetic, but also social, political and economic contexts by 2030. The first one corresponds to a severe energy crisis with an emergence of regional governance. The second one corresponds to a high volatility of energy prices, an increased easing of restrictions on trade, and a decrease of public supports and subsidies for agriculture. The third one corresponds to a strong reduction of the use of phyto-sanitary products in agriculture, a continuous urban sprawl, and the prevalence of road transport. The fourth one corresponds to agriculture respectful of the environment and a good management of energy consumption. Direct and indirect energy consumptions are assessed for the four scenarios. Some general and operational objectives are thus identified

Comparative analysis of environmental impacts of agricultural production systems, agricultural input efficiency, and food choice

Science.gov (United States)

Clark, Michael; Tilman, David

2017-06-01

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

Janina Borysiak

2018-03-01

Full Text Available The study aim was to define the landscape determinants as certificates of natural and cultural heritage which identify the young glacial landscape under traditional agricultural management. These studies were conducted in the upper Parsęta basin (Pomerania, Poland covered by the many annual environmental monitoring programs since 1994. The aim of this monitoring is to observe changes in geoecosystems of the temperate climate zone. The parameters of the abiotic landscape subsystem have been monitored in a wide range of terms, whereas biotic elements and cultural resources only in a very limited way. This was the reason for undertaking complementary studies. The paper presents the so-called “zero-state” for 2014, which will be a reference point from which to track the direction of landscape changes in the future. The abiotic, geobotanical, and cultural determinants of this state chosen have been characterized on the basis of field mapping data and the available literature. They were chosen based on the methodology of landscape audit to define the specificity of the traditional agricultural landscape. They were selected on the basis of assessment criteria for landscape structure: complexity (diversification of land use and cover, naturalness (syngenesis of plant communities, hydrochemical properties of surface waters, coherence of composition with natural conditions, stewardship (intensity of use, crop weeds, ecological succession, fallows, anthropogenic denudation, aesthetic and visual perception, historicity (continuity of natural landscape elements, continuation of traditional agricultural use, architectural objects, and disharmonious elements.

Nyambo, Calistor; Mohanty, Amar K; Misra, Manjusri

2010-06-14

Agricultural natural fibers like jute, kenaf, sisal, flax, and industrial hemp have been extensively studied in green composites. The continuous supply of biofibers in high volumes to automotive part makers has raised concerns. Because extrusion followed by injection molding drastically reduces the aspect ratio of biofibers, the mechanical performance of injection molded agricultural residue and agricultural fiber-based composites are comparable. Here, the use of inexpensive agricultural residues and their hybrids that are 8-10 times cheaper than agricultural fibers is demonstrated to be a better way of getting sustainable materials with better performance. Green renewable composites from polylactide (PLA), agricultural residues (wheat straw, corn stover, soy stalks, and their hybrids) were successfully prepared through twin-screw extrusion, followed by injection molding. The effect on mechanical properties of varying the wheat straw amount from 10 to 40 wt % in PLA-wheat straw composites was studied. Tensile moduli were compared with theoretical calculations from the rule of mixture (ROM). Combination of agricultural residues as hybrids is proved to reduce the supply chain concerns for injection molded green composites. Densities of the green composites were found to be lower than those of conventional glass fiber composites.

Towards Conservation Agriculture systems in Moldova

Directory of Open Access Journals (Sweden)

Boris Boincean

2016-10-01

Full Text Available As the world population and food production demands rise, keeping agricultural soils and landscapes healthy and productive are of paramount importance to sustaining local and global food security and the flow of ecosystem services to society. The global population, expected to reach 9.7 billion people by 2050, will put additional pressure on the available land area and resources for agricultural production. Sustainable production intensification for food security is a major challenge to both industrialized and developing countries. The paper focuses on the results from long-term multi-factorial experiments involving tillage practices, crop rotations and fertilization to study the interactions amongst the treatments in the context of sustainable production intensification. The paper discusses the results in relation to reported performance of crops and soil quality in Conservation Agriculture systems that are based on no or minimum soil disturbance (no-till seeding and weeding, maintenance of soil mulch cover with crop biomass and cover crops, and diversified cropping s involving annuals and perennials. Conservation Agriculture also emphasizes the necessity of an agro-ecosystems approach to the management of agricultural land for sustainable production intensification, as well as to the site-specificity of agricultural production. Arguments in favor of avoiding the use of soil tillage are discussed together with agro-ecological principles for sustainable intensification of agriculture. More interdisciplinary systems research is required to support the transformation of agriculture from the conventional tillage agriculture to a more sustainable agriculture based on the principles and practices of Conservation Agriculture, along with other complementary practices of integrated crop, nutrient, water, pest, energy and farm power management.

In this respect, a series of economic indicators as the contribution of agriculture to GDP, the value of agricultural production, the evolution of reference interest rate, the evolution of credits for agriculture, were studied. the conclusion was that in order to improve labour productivity, it is needed a higher qualification of the occupied population in agriculture and the significant improvement of technological endowment of this sector and, from the point of view of funding access, it is necessary the continuous support of the companies which carry out their activity in agriculture, but not only by the diminution of difference interest rate.

Preservation of Agricultural Land as an Issue of Societal Importance

Directory of Open Access Journals (Sweden)

Elin Slätmo

2017-12-01

Full Text Available Based on concerns about food security and food sovereignty, it is appropriate to scrutinise societal measures for protecting agricultural land from conversion to other uses. Changes from agricultural to urban land use are particularly problematic, as they are largely irreversible. By analysing relevant Swedish policy, the present study investigated how the protection of agricultural land is framed as an issue of societal importance. Protection of agricultural land is enshrined in Swedish law, but its use is still continually changing to housing and other constructions. In a structured policy analysis, two questions were examined: (1 what are the societal motives for protecting agricultural land in Sweden, and (2 how do these motives influence the governance of agricultural land? The meaning of ‘national importance’, ‘suitable for cultivation’ and ‘significant national interests’ in Swedish land-use law was also analysed. The results showed that formulations in the law reflect the ambivalent discourses on agricultural land preservation and that the Swedish authorities view other land uses as more important than agriculture. The Swedish governance system is currently built on trust that municipal institutions will make satisfactory decisions concerning land and water use. However, it has been shown that these decisions have not been satisfactory concerning the protection of agricultural land, and it is important to acknowledge that the sum of local decisions can be degrading for these life-supporting resources. The present analysis revealed a looming conflict between the preservation of soils for food production, on one hand, and local participation in decision making, on the other. This raises the question of whether it is more important to defend subsidiarity or to preserve certain resources which are important for food security, such as agricultural land.

Measuring Agricultural Bias

DEFF Research Database (Denmark)

Jensen, Henning Tarp; Robinson, Sherman; Tarp, Finn

The measurement issue is the key issue in the literature on trade policy-induced agri-cultural price incentive bias. This paper introduces a general equilibrium effective rate of protection (GE-ERP) measure, which extends and generalizes earlier partial equilibrium nominal protection measures...... shares and intersectoral linkages - are crucial for determining the sign and magnitude of trade policy bias. The GE-ERP measure is therefore uniquely suited to capture the full impact of trade policies on agricultural price incentives. A Monte Carlo procedure confirms that the results are robust....... For the 15 sample countries, the results indicate that the agricultural price incentive bias, which was generally perceived to exist during the 1980s, was largely eliminated during the 1990s. The results also demonstrate that general equilibrium effects and country-specific characteristics - including trade...

The true extent of agriculture's contribution to national greenhouse gas emissions

International Nuclear Information System (INIS)

Bell, M.J.; Cloy, J.M.; Rees, R.M.

2014-01-01

Highlights: • Quantification of agricultural GHG emissions is required under legislation. • Alternative approaches to calculating agricultural GHG inventories were compared. • The Scottish Government and IPCC attribute different emissions to the agricultural sector. • High emissions from agriculture are calculated when land-use change is included. • Agriculture is a greater source of emissions using the Scottish Government approach. - Abstract: The agricultural sector is a significant contributor to greenhouse gas (GHG) emissions, and a growing global population means that agricultural production will remain high if food demands are to be met. Mitigation methods to reduce emissions from this sector are thus required, along with identification and quantification of emission sources, so that the agricultural community can act and measure its progress. International legislation requires the submission of annual reports quantifying GHG emissions from agriculture. The importance of attributing the correct sources of emissions to the agricultural sector is clear; however the current approach taken by the IPCC, and reported to the UNFCCC, omits emissions from soils during agricultural land-use change from its agricultural inventory. This paper questions the IPCC approach, and the attribution of agricultural land-use change emissions to a separate category: ‘Land-use, Land-use change and Forestry’. Here a new approach adopted by the Scottish Government is examined, and compared to IPCC guidelines and national communications submitted to the Department of Energy and Climate Change (DECC) and the UNFCCC. The new Scottish Government approach attributes emissions from both land-use conversion and agricultural land under continuous use to the agricultural sector, in addition to those emissions from livestock and energy use on farms. The extent of emissions attributed to the agricultural sector using the Scottish Government approach is much greater than that using

Bulgarian agriculture in the conditions of the EU Common Agricultural Policy

Full Text Available The agricultural sectors of the former centrally planned economies, including Bulgaria were in a state of economic crises in the period after socialist governments fell. The former system disappeared almost overnight while new market structures had not yet emerged. The outcome of this transition shocks was a sharp decline in both agricultural output and the sector's GDP in the early 1990s. Some countries of the Central and Eastern Europe (CEE recovered from this initial decline much faster. The principle reason for the difference appears to be the more resolute adherence of CEE governments to reform policies throughout their economies. The purpose of this study is to get more knowledge about the structure and possibilities of Bulgarian agriculture after the transition period and last but not least, about the effects of the EU CAP on the Bulgarian economy and farmers.That is why were made some interviews, and besides, it was carried out a questionnaire survey in order to get a picture about how farmers act in a new environment called the Common Agricultural Policy of EU. For collecting information, as well as confirming or rejecting the investigation hypotheses chi-square analysis was applied.

Migrant Workers in Agriculture: A View from Thailand.

Science.gov (United States)

Thetkathuek, Anamai; Daniell, William

2016-01-01

There has been a dramatic increase in the global movement of workers during the last few decades. As Thailand has developed rapidly over the past 20 years, it has attracted laborers (both authorized and unauthorized) from the neighboring countries of Myanmar, People's Democratic Republic of Lao (Lao PDR), and Cambodia. Given that agriculture has been Thailand's most important industry, its continued growth has been dependent on migrant workers. Both crop agriculture and animal-production agriculture have employed migrant labor. Migrants have been hired to plant, weed, fertilize, spray pesticides, and harvest crops such as rice, corn, sugar cane, and cassava. They have worked at rubber and coffee plantations, as well as in the production of ornamental crops. Also, migrants have labored on pig, beef, and duck farms. There have been numerous documented health problems among migrant workers, including acute diarrhea, malaria, and fever of unknown causes. Occupational illness and injury have been a significant concern, and there has been limited health and safety training. This article reviewed the demographic changes in Thailand, studied the agricultural crops and animal production that are dependent on migrant labor, discussed the health status and safety challenges pertaining to migrant workers in agriculture, and described several recommendations. Among the recommendations, the conclusions of this study have suggested that addressing the cost for health care and solutions to health care access for migrant labor are needed.

Agricultural expansion and its impacts on tropical nature.

Science.gov (United States)

Laurance, William F; Sayer, Jeffrey; Cassman, Kenneth G

2014-02-01

The human population is projected to reach 11 billion this century, with the greatest increases in tropical developing nations. This growth, in concert with rising per-capita consumption, will require large increases in food and biofuel production. How will these megatrends affect tropical terrestrial and aquatic ecosystems and biodiversity? We foresee (i) major expansion and intensification of tropical agriculture, especially in Sub-Saharan Africa and South America; (ii) continuing rapid loss and alteration of tropical old-growth forests, woodlands, and semi-arid environments; (iii) a pivotal role for new roadways in determining the spatial extent of agriculture; and (iv) intensified conflicts between food production and nature conservation. Key priorities are to improve technologies and policies that promote more ecologically efficient food production while optimizing the allocation of lands to conservation and agriculture.

2014-12-01

Climate-smart agriculture (CSA) is an approach for transforming and reorienting agricultural systems to support food security under the new realities of climate change. Widespread changes in rainfall and temperature patterns threaten agricultural production and increase the vulnerability of people dependent on agriculture for their livelihoods, which includes most of the world's poor. Climate change disrupts food markets, posing population-wide risks to food supply. Threats can be reduced by increasing the adaptive capacity of farmers as well as increasing resilience and resource use efficiency in agricultural production systems. CSA promotes coordinated actions by farmers, researchers, private sector, civil society and policymakers towards climate-resilient pathways through four main action areas: (1) building evidence; (2) increasing local institutional effectiveness; (3) fostering coherence between climate and agricultural policies; and (4) linking climate and agricultural financing. CSA differs from 'business-as-usual' approaches by emphasizing the capacity to implement flexible, context-specific solutions, supported by innovative policy and financing actions.

EXPERT SYSTEMS - DEVELOPMENT OF AGRICULTURAL INSURANCE TOOL

Directory of Open Access Journals (Sweden)

NAN Anca-Petruţa

2013-07-01

Full Text Available Because of the fact that specialty agricultural assistance is not always available when the farmers need it, we identified expert systems as a strong instrument with an extended potential in agriculture. This started to grow in scale recently, including all socially-economic activity fields, having the role of collecting data regarding different aspects from human experts with the purpose of assisting the user in the necessary steps for solving problems, at the performance level of the expert, making his acquired knowledge and experience available. We opted for a general presentation of the expert systems as well as their necessity, because, the solution to develop the agricultural system can come from artificial intelligence by implementing the expert systems in the field of agricultural insurance, promoting existing insurance products, farmers finding options in depending on their necessities and possibilities. The objective of this article consists of collecting data about different aspects about specific areas of interest of agricultural insurance, preparing the database, a conceptual presentation of a pilot version which will become constantly richer depending on the answers received from agricultural producers, with the clearest exposure of knowledgebase possible. We can justify picking this theme with the fact that even while agricultural insurance plays a very important role in agricultural development, the registered result got from them are modest, reason why solutions need to be found in the scope of developing the agricultural sector. The importance of this consists in the proposal of an immediate viable solution to correspond with the current necessities of agricultural producers and in the proposal of an innovative solution, namely the implementation of expert system in agricultural insurance as a way of promoting insurance products. Our research, even though it treats the subject at an conceptual level, it wants to undertake an

China is a large agricultural country, and the healthy development of agriculture is related to the stability of the whole society. The agricultural production and management of agricultural products are confronted with many risks, especially the market risks. Option contract is the object of option market transaction, so it is very important to study the option contract of agricultural products. Option trading separates the risk and profit, so that the trader can avoid the risk while retaining the opportunity to obtain income. The option has the characteristics of low transaction cost, simple and efficient, so it is suitable for small and medium investors.

1997-01-01

Local agricultural practices in the Nordic countries have resulted in a great diversity in agriculture in the Nordic countries. The diversities mean that in the event of contamination of agricultural land by radioactive fallout the consequences may differ greatly from region to region. For crops and soils contaminated directly by radioactive fallout there are five primary causes for concern, namely: 1. short-term internal contamination of man and animals through ingestion of surface-contaminated mature crops; 2. internal contamination of crops through foliar intake; 3. contamination of mature crops from resuspended soil; 4. direct irradiation of agricultural workers; 5. internal irradiation from inhalation of resuspended soil particulates. In the short-term, most of the radionuclides likely to be released to the atmosphere in the event of an accident have a potential to cause problems in agriculture and many have the potential for causing long-term problems. Generally, the magnitude of the problems created will depend on the: deposition mechanism (wet or dry); radionuclide composition of the fallout; type of farming system (i.e. arable or dairy); type of soil (for instance organic soils are more sensitive than mineral soils with respect to radiocaesium); state of development of the crop which in turn is determined by the season of the year.

Perceived agricultural runoff impact on drinking water.

Science.gov (United States)

Crampton, Andrea; Ragusa, Angela T

2014-09-01

Agricultural runoff into surface water is a problem in Australia, as it is in arguably all agriculturally active countries. While farm practices and resource management measures are employed to reduce downstream effects, they are often either technically insufficient or practically unsustainable. Therefore, consumers may still be exposed to agrichemicals whenever they turn on the tap. For rural residents surrounded by agriculture, the link between agriculture and water quality is easy to make and thus informed decisions about water consumption are possible. Urban residents, however, are removed from agricultural activity and indeed drinking water sources. Urban and rural residents were interviewed to identify perceptions of agriculture's impact on drinking water. Rural residents thought agriculture could impact their water quality and, in many cases, actively avoided it, often preferring tank to surface water sources. Urban residents generally did not perceive agriculture to pose health risks to their drinking water. Although there are more agricultural contaminants recognised in the latest Australian Drinking Water Guidelines than previously, we argue this is insufficient to enhance consumer protection. Health authorities may better serve the public by improving their proactivity and providing communities and water utilities with the capacity to effectively monitor and address agricultural runoff.

This study aimed at observing the development of agricultural land use in Bungo Regency, Jambi Province, for other purposes, such as plantation, mining, and other commercial buildings. According to the sustainable agriculture supposed by the government, a change in land use has become an important issue to be taken into account as such that the change does not tend to damage the environment. The research findings from Bungo Regency demonstrated the change in agricultural land into copra and rubber plantation areas. Local people had changed their mindset towards reluctance to become farmers, which caused the loss of farmer regeneration and weakened the farmer exchange rate towards the agricultural commodities.

Pulmonary health effects of agriculture.

Nordgren, Tara M; Bailey, Kristina L

2016-03-01

Occupational exposures in the agricultural industry are associated with numerous lung diseases, including chronic obstructive pulmonary disease, asthma, hypersensitivity pneumonitis, lung cancer, and interstitial lung diseases. Efforts are ongoing to ascertain contributing factors to these negative respiratory outcomes and improve monitoring of environmental factors leading to disease. In this review, recently published studies investigating the deleterious effects of occupational exposures in the agricultural industry are discussed. Occupational exposures to numerous agricultural environment aerosols, including pesticides, fungi, and bacteria are associated with impaired respiratory function and disease. Increases in certain farming practices, including mushroom and greenhouse farming, present new occupational exposure concerns. Improved detection methods may provide opportunities to better monitor safe exposure levels to known lung irritants. In the agricultural industry, occupational exposures to organic and inorganic aerosols lead to increased risk for lung disease among workers. Increased awareness of respiratory risks and improved monitoring of agricultural environments are necessary to limit pulmonary health risks to exposed populations.

During the Responding to HIV/AIDS: Technology Development Needs for African Smallholder Agriculture Conference in Harare, about 70 delegates participated from government and nongovernmental organizations, community-based organizations, agricultural research, and regional and international organizations. The aims of the conference were to analyze the impact of HIV/AIDS on smallholder agriculture; identify the necessary technologies, policy, and institutional responses; and propose frameworks for future activities. The conference participants noted that the onset of HIV/AIDS has changed the African rural environment in which existing policy and programs on agriculture have been operating. In view of this, recommendations on technology and development and policy to mitigate the impact of the epidemic were highlighted; namely, promote existing labor and capital saving technologies; review existing agricultural extension; develop appropriate technologies to reduce the time spent on water and fuel collection; develop income-generating activities; strengthen existing community-based initiatives; and redefine the criteria for land tenure and ownership. Moreover, collaboration between development organizations and applied research were also emphasized.

Barriers to Conducting Supervised Agricultural Experiences as Perceived by Preservice Agricultural Education Teachers

Directory of Open Access Journals (Sweden)

J. Joey Blackburn

2014-10-01

Full Text Available The purpose of this descriptive study was to assess preservice agriculture teachers’ perceptions of the importance of Supervised Agricultural Experience (SAE and their views on barriers to conducting SAE. A census of the sophomore-level agricultural education course at Oklahoma State University was conducted to measure perceptions at the beginning and end of the course. This study was framed upon Ajzen’s Theory of Planned Behavior. Results indicated that preservice teachers perceived SAE was an important component of agricultural education and important at the secondary school they attended. The greatest barrier to conducting SAE was their lack of familiarity with newer SAE categories. This was true at both the beginning and end of the course. It is recommended that preservice teachers receive instruction on and experiences in all types of SAE. This would increase the likelihood of preservice teachers perceiving they have control over this barrier regarding SAE implementation. This cohort of preservice teachers should be surveyed over time to determine change in their perceptions of barriers to SAE implementation as they progress in the agricultural education program and through their careers. Further, the views of in-service teachers should also be assessed to determine if perceived barriers differ with professional experience.

Watershed sediment losses to lakes accelerating despite agricultural soil conservation efforts.

Science.gov (United States)

Heathcote, Adam J; Filstrup, Christopher T; Downing, John A

2013-01-01

Agricultural soil loss and deposition in aquatic ecosystems is a problem that impairs water quality worldwide and is costly to agriculture and food supplies. In the US, for example, billions of dollars have subsidized soil and water conservation practices in agricultural landscapes over the past decades. We used paleolimnological methods to reconstruct trends in sedimentation related to human-induced landscape change in 32 lakes in the intensively agricultural region of the Midwestern United States. Despite erosion control efforts, we found accelerating increases in sediment deposition from erosion; median erosion loss since 1800 has been 15.4 tons ha(-1). Sediment deposition from erosion increased >6-fold, from 149 g m(-2) yr(-1) in 1850 to 986 g m(-2) yr(-1) by 2010. Average time to accumulate one mm of sediment decreased from 631 days before European settlement (ca. 1850) to 59 days mm(-1) at present. Most of this sediment was deposited in the last 50 years and is related to agricultural intensification rather than land clearance or predominance of agricultural lands. In the face of these intensive agricultural practices, traditional soil conservation programs have not decelerated downstream losses. Despite large erosion control subsidies, erosion and declining water quality continue, thus new approaches are needed to mitigate erosion and water degradation.

Full Text Available The use of Unmanned Aerial Vehicle (UAV tools has become widespread in map production, land surveying, landslide, erosion monitoring, monitoring of agricultural activities, aerial crop surveying, forest fire detection and monitoring operations. In this study, GEO 2 UAV manufactured by TEKNOMER equipped with SONY A6000 camera has been used. The flight plan have been performed with 100 m altitude, with 80% longitudinal and 60% side overlapping. Ground Control Points (GCPs have been observed with Topcon and Trimble GNSS geodetic receivers. Recorded GNSS signals have been processed with LGO V.8.4 software to get sensitive location information. 985 photos have been taken for the 344 hectares the agricultural area. 291 photos have been taken for 50 hectares the landslide area. All photos were processed by PIX4D software. For the agricultural area, 25 GCPs and for the landslide area, 8 GCPs have been included in the evaluation. 3D images were produced with pixel matching algorithms. As a result, the RMS evaluation was obtained as ±0.054 m for the agricultural area and as ±0.018 m for the landslide area. UAV images have indisputable contributions to the management of catastrophes such as landslides and earthquakes, and it is impossible to make terrestrial measurements in areas where disaster impact continues.

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

Science.gov (United States)

Muldowney, J; Mounsey, J; Kinsella, L

2013-06-01

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

Relationship between biodiversity and agricultural production

OpenAIRE

Brunetti, Ilaria; Tidball, Mabel; Couvet, Denis

2018-01-01

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

A process-based agricultural model for the irrigated agriculture sector in Alberta, Canada

Science.gov (United States)

Ammar, M. E.; Davies, E. G.

2015-12-01

Connections between land and water, irrigation, agricultural productivity and profitability, policy alternatives, and climate change and variability are complex, poorly understood, and unpredictable. Policy assessment for agriculture presents a large potential for development of broad-based simulation models that can aid assessment and quantification of policy alternatives over longer temporal scales. The Canadian irrigated agriculture sector is concentrated in Alberta, where it represents two thirds of the irrigated land-base in Canada and is the largest consumer of surface water. Despite interest in irrigation expansion, its potential in Alberta is uncertain given a constrained water supply, significant social and economic development and increasing demands for both land and water, and climate change. This paper therefore introduces a system dynamics model as a decision support tool to provide insights into irrigation expansion in Alberta, and into trade-offs and risks associated with that expansion. It is intended to be used by a wide variety of users including researchers, policy analysts and planners, and irrigation managers. A process-based cropping system approach is at the core of the model and uses a water-driven crop growth mechanism described by AquaCrop. The tool goes beyond a representation of crop phenology and cropping systems by permitting assessment and quantification of the broader, long-term consequences of agricultural policies for Alberta's irrigation sector. It also encourages collaboration and provides a degree of transparency that gives confidence in simulation results. The paper focuses on the agricultural component of the systems model, describing the process involved; soil water and nutrients balance, crop growth, and water, temperature, salinity, and nutrients stresses, and how other disciplines can be integrated to account for the effects of interactions and feedbacks in the whole system. In later stages, other components such as

Agricultural systems science generates knowledge that allows researchers to consider complex problems or take informed agricultural decisions. The rich history of this science exemplifies the diversity of systems and scales over which they operate and have been studied. Modeling, an essential tool in agricultural systems science, has been accomplished by scientists from a wide range of disciplines, who have contributed concepts and tools over more than six decades. As agricultural scientists now consider the "next generation" models, data, and knowledge products needed to meet the increasingly complex systems problems faced by society, it is important to take stock of this history and its lessons to ensure that we avoid re-invention and strive to consider all dimensions of associated challenges. To this end, we summarize here the history of agricultural systems modeling and identify lessons learned that can help guide the design and development of next generation of agricultural system tools and methods. A number of past events combined with overall technological progress in other fields have strongly contributed to the evolution of agricultural system modeling, including development of process-based bio-physical models of crops and livestock, statistical models based on historical observations, and economic optimization and simulation models at household and regional to global scales. Characteristics of agricultural systems models have varied widely depending on the systems involved, their scales, and the wide range of purposes that motivated their development and use by researchers in different disciplines. Recent trends in broader collaboration across institutions, across disciplines, and between the public and private sectors suggest that the stage is set for the major advances in agricultural systems science that are needed for the next generation of models, databases, knowledge products and decision support systems. The lessons from history should be

Successful integration of nutrition interventions into large-scale development programmes from nutrition-relevant sectors, such as agriculture, can address critical underlying determinants of undernutrition and enhance the coverage and effectiveness of on-going nutrition-specific activities. However, evidence on how this can be done is limited. This study examines the feasibility of delivering maternal, infant, and young child nutrition behaviour change communication through an innovative agricultural extension programme serving nutritionally vulnerable groups in rural India. The existing agriculture programme involves participatory production of low-cost videos promoting best practices and broad dissemination through village-level women's self-help groups. For the nutrition intervention, 10 videos promoting specific maternal, infant, and young child nutrition practices were produced and disseminated in 30 villages. A range of methods was used to collect data, including in-depth interviews with project staff, frontline health workers, and self-help group members and their families; structured observations of mediated video dissemination sessions; nutrition knowledge tests with project staff and self-help group members; and a social network questionnaire to assess diffusion of promoted nutrition messages. We found the nutrition intervention to be well-received by rural communities and viewed as complementary to existing frontline health services. However, compared to agriculture, nutrition content required more time, creativity, and technical support to develop and deliver. Experimentation with promoted nutrition behaviours was high, but sharing of information from the videos with non-viewers was limited. Key lessons learned include the benefits of and need for collaboration with existing health services; continued technical support for implementing partners; engagement with local cultural norms and beliefs; empowerment of women's group members to champion nutrition

Having it both ways? Land use change in a U.S. midwestern agricultural ecoregion

Auch, Roger F.; Laingen, Chris R.

2015-01-01

Urbanization has been directly linked to decreases in area of agricultural lands and, as such, has been considered a threat to food security. Although the area of land used to produce food has diminished, often overlooked have been changes in agricultural output. The Eastern Corn Belt Plains (ECBP) is an important agricultural region in the U.S. Midwest. It has both gained a significant amount of urban land, primarily from the conversion of agricultural land between 1973 and 2000, and at the same time continued to produce ever-increasing quantities of agricultural products. By 2002, more corn, soybeans, and hogs were produced on a smaller agricultural land base than in 1974. In the last quarter of the twentieth century, ECBP ecoregion society appeared to have “had it both ways”: more urbanization along with increased agricultural output.

Reduction of radiation injury of fresh agricultural products by saccharide

1999-01-01

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

Full Text Available Modern agricultural applications contain various biologic physical and chemical process steps to maximize the durability and fertility of the products. Because of the apprehensions that come out as a result of increase in usage of chemical input in these processes, some alternative concepts have been come to exist for modern agricultural applications. Even these approaches match with traditional applications, they differ by their some outstanding features. By the help of industrial devolution in 18TH century, the increasing popularity and global warming caused the people to notice the ecologic deformation on the earth and accordingly saving the ecology and the earth became one of the main topics of current issues. The biodynamic agriculture system is founded in 1924 by Rudolf Steiner (philosopher and E. Pfeiffer (agronomist and built on an anthropologic theory that based on human-nature-universe concept. Biodynamic agriculture is familiar with organic agriculture. Mainly both of them are originated by oppositional perspective on using chemical input (manure, pesticide, herbicide, hormone e.g.. The main dissimilitude of biodynamic agriculture with organic apart from philosophical and historical aspects is, using the biodynamic preparations includes some minerals or specific herbs those are fermented with animal organs. In this review study, the differences between organic and biodynamic agriculture are analysed by emphasizing the main advantages of biodynamic agriculture.

Agricultural sources of greenhouse gas emissions

International Nuclear Information System (INIS)

Rochette, P.

2003-01-01

The author described different sources of greenhouse gas emissions resulting from agricultural activities and the process by which carbon dioxide, nitrous oxide, and methane are generated on Canadian farms. The author also proposed some practices that would contribute to the reduction of greenhouse gas emissions. A brief description of the greenhouse effect was also provided with special emphasis on the agricultural sector. In 1996, the Canadian agricultural sector was responsible for approximately 10 per cent of greenhouse gas emissions in the country. Given the increase in farm animals and more intensive agricultural activities, it is estimated that greenhouse gas emissions generated by the agricultural sector will increase by 20 per cent by 2010 if current practices remain in effect. The most optimistic scenarios indicate that the agricultural sector could achieve or even exceed Canada's Kyoto Protocol commitments mainly through organic material sequestration in soils. The possibility for farmers to sell greenhouse gas credits could motivate farmers into adopting various practices that reduce emissions of greenhouse gases. However, the author indicated that the best motivation for farmers is the fact that adopting such practices would also lead to more efficient agricultural production. 5 refs., 4 figs

Full Text Available Agriculture posed considerable tensions for the processes of enlargement of the European Union, because of its continuing importance both in the economies of the applicant countries of Central and Eastern European countries which have joined EU on the 1st may 2004., and in the EU budget and acquits communautaire. The preparation of agriculture in the candidate countries to join the EU was rendered more complex by the fact that the Community's Common Agricultural Policy was a moving target. The aim of this paper is to show the bases elements of the Common Agricultural Policy, but also to provide a survey of recent developments relating to agriculture in the EU and new member states of the EU before their accession to EU and their preparation to access on the enlarged market, in order to indicate the main challenges and difficulties posed by enlargement. It seems likely that agricultural policy in the enlarged EU will attach increased priority to objectives such as rural development and the environment. However, these new priorities may be expensive to realize, and may impose a growing burden on the national budgets of EU member states.

Identification of Decisive Factors Determining the Continued Use of Rainwater Harvesting Systems for Agriculture Irrigation in Beijing

Directory of Open Access Journals (Sweden)

Xiao Liang

2015-12-01

Full Text Available The success or failure of operating a rainwater harvesting system (RWH depends on both technological and non-technological factors. The importance of non-technological factors in attaining sustainable RWH operation is rarely emphasized. This study aims to assess the contribution of non-technological factors through determining decisive factors involved in the use of RWHs for agriculture irrigation in Beijing. The RWHs for agriculture irrigation in Beijing are not operating as well as expected. If the decisive factors are identified to be non-technological, the significance of non-technological factors will be highlighted. Firstly, 10 impact factors comprising non-technological and technological factors are selected according to both a literature review and interviews with RWH managers. Following this, through an artificial data mining method, rough set analysis, the decisive factors are identified. Results show that two non-technological factors, “doubts about rainwater quality” and “the availability of groundwater” determine whether these systems will continue or cease RWH operation in Beijing. It is, thus, considered necessary to improve public confidence in and motivation on using rainwater for agriculture irrigation, as this is the main obstacle in the sustainable and successful operation of RWHs. Through a case study of RWHs in Beijing, the study verifies the importance of acknowledging non-technological factors to achieve sustainable water management and considers that such factors should receive more attention by decision makers and researchers.

Climate change and water availability for vulnerable agriculture

Science.gov (United States)

Dalezios, Nicolas; Tarquis, Ana Maria

2017-04-01

Climatic projections for the Mediterranean basin indicate that the area will suffer a decrease in water resources due to climate change. The key climatic trends identified for the Mediterranean region are continuous temperature increase, further drying with precipitation decrease and the accentuation of climate extremes, such as droughts, heat waves and/or forest fires, which are expected to have a profound effect on agriculture. Indeed, the impact of climate variability on agricultural production is important at local, regional, national, as well as global scales. Agriculture of any kind is strongly influenced by the availability of water. Climate change will modify rainfall, evaporation, runoff, and soil moisture storage patterns. Changes in total seasonal precipitation or in its pattern of variability are both important. Similarly, with higher temperatures, the water-holding capacity of the atmosphere and evaporation into the atmosphere increase, and this favors increased climate variability, with more intense precipitation and more droughts. As a result, crop yields are affected by variations in climatic factors, such as air temperature and precipitation, and the frequency and severity of the above mentioned extreme events. The aim of this work is to briefly present the main effects of climate change and variability on water resources with respect to water availability for vulnerable agriculture, namely in the Mediterranean region. Results of undertaken studies in Greece on precipitation patterns and drought assessment using historical data records are presented. Based on precipitation frequency analysis, evidence of precipitation reductions is shown. Drought is assessed through an agricultural drought index, namely the Vegetation Health Index (VHI), in Thessaly, a drought-prone region in central Greece. The results justify the importance of water availability for vulnerable agriculture and the need for drought monitoring in the Mediterranean basin as part of

A comprehensive bibliography (417 refs.) on analysis and use of the stable isotope 15 N in soil-plant relations research, animal nutrition and physiology, environmental research, and further disciplines related to agricultural problems is presented. The literature pertaining to this review covers the period from 1978 to 1980. Among the stable isotopes of biological interest 15 N is characterized by an exclusive use in agricultural studies. Recent progress and trends of development in sample treatment and analysis of 15 N are cited. A great number of experiments has shown that from the technical as well as the biological point of view 15 N is the ideal isotope for these investigations, nevertheless expense and analytical problems are considerable. The combined efforts of theorists and experimenters will be required for continued advances in theory and use of stable isotopes as tracers. (author)

Emergy Evaluations of Denmark and Danish Agriculture. Assessing the Limits of Agricultural Systems to Power Society

Energy Technology Data Exchange (ETDEWEB)

Haden, Andrew C [Swedish Univ. of Agricultural Sciences, Uppsala (Sweden). Dept. of Rural Development Studies

2003-03-01

As the process of industrialization has run its course over the twentieth century, the relative importance of agriculture as an economic activity and a means of cultural sustenance for nations has declined dramatically. In this thesis, a historical ecological-economic perspective offers insights into both the causes and effects of Danish agriculture's decline in economic importance relative to the economy of Denmark as a whole. Emergy evaluations were made of the national economy and agricultural subsystem of Denmark for the years 1936, 1970 and 1999. Emergy is defined as all the available energy that was used in the work of making a product and expressed in units of one type of energy. In total, six separate emergy analyses were performed. By quantifying the emergy requirements of both a national agricultural system and the economy within which this system is nested, the analysis highlights the changing relationship of these two systems over a temporal scale of 63 years. The ecological sustainability of the studied systems is assessed through the calculation of emergy-based indices and ratios. In accordance with emergy theory, ecological sustainability is considered to be a function of the dependence of a system on renewable emergy, the degree to which the system depends on imported emergy, and the overall load that the system places on the environment. The analysis indicates that as the national economy of Denmark evolved to rely more on the use of nonrenewable emergy and on emergy appropriated through trade to stimulate economic activity and to generate wealth, its sustainability declined, and the importance of the Danish agricultural system to the national economy subsided. While the total amount of emergy supporting the economy of Denmark over the period studied increased substantially, the total emergy supporting agriculture remained relatively constant. Furthermore, though the emergy signature and thermodynamic efficiencies of Danish agricultural production

Climate Change and Agricultural Vulnerability

International Nuclear Information System (INIS)

Fischer, G.; Shah, M.; Van Velthuizen, H.

2002-08-01

After the introduction Chapter 2 presents details of the ecological-economic analysis based on the FAO/IIASA agro-ecological zones (AEZ) approach for evaluation of biophysical limitations and agricultural production potentials, and IIASA's Basic Linked System (BLS) for analyzing the world's food economy and trade system. The BLS is a global general equilibrium model system for analyzing agricultural policies and food system prospects in an international setting. BLS views national agricultural systems as embedded in national economies, which interact with each other through trade at the international level. The combination of AEZ and BLS provides an integrated ecological-economic framework for the assessment of the impact of climate change. We consider climate scenarios based on experiments with four General Circulation Models (GCM), and we assess the four basic socioeconomic development pathways and emission scenarios as formulated by the Intergovernmental Panel on Climate Change (IPCC) in its Third Assessment Report. Chapter 3 presents the main AEZ results of the impact of climate change on agriculture. Results comprise environmental constraints to crop agriculture; climate variability and the variability of rain-fed cereal production; changes in potential agricultural land; changes in crop-production patterns; and the impact of climate change on cereal-production potential. Chapter 4 discusses the AEZ-BLS integrated ecological-economic analysis of climate change on the world food system. This includes quantification of scale and location of hunger, international agricultural trade, prices, production, land use, etc. It assesses trends in food production, trade, and consumption, and the impact on poverty and hunger of alternative development pathways and varying levels of climate change. Chapter 5 presents the main conclusions and policy implications of this study

Continuous 'Passive' Registration of Non-Point Contaminant Loads Via Agricultural Subsurface Drain Tubes

Science.gov (United States)

Rozemeijer, J.; Jansen, S.; de Jonge, H.; Lindblad Vendelboe, A.

2014-12-01

Considering their crucial role in water and solute transport, enhanced monitoring and modeling of agricultural subsurface tube drain systems is important for adequate water quality management. For example, previous work in lowland agricultural catchments has shown that subsurface tube drain effluent contributed up to 80% of the annual discharge and 90-92% of the annual NO3 loads from agricultural fields towards the surface water. However, existing monitoring techniques for flow and contaminant loads from tube drains are expensive and labor-intensive. Therefore, despite the unambiguous relevance of this transport route, tube drain monitoring data are scarce. The presented study aimed developing a cheap, simple, and robust method to monitor loads from tube drains. We are now ready to introduce the Flowcap that can be attached to the outlet of tube drains and is capable of registering total flow, contaminant loads, and flow-averaged concentrations. The Flowcap builds on the existing SorbiCells, a modern passive sampling technique that measures average concentrations over longer periods of time (days to months) for various substances. By mounting SorbiCells in our Flowcap, a flow-proportional part of the drain effluent is sampled from the main stream. Laboratory testing yielded good linear relations (R-squared of 0.98) between drainage flow rates and sampling rates. The Flowcap was tested in practice for measuring NO3 loads from two agricultural fields and one glasshouse in the Netherlands. The Flowcap registers contaminant loads from tube drains without any need for housing, electricity, or maintenance. This enables large-scale monitoring of non-point contaminant loads via tube drains, which would facilitate the improvement of contaminant transport models and would yield valuable information for the selection and evaluation of mitigation options to improve water quality.

In the early years of the twentieth century, Australia's leading economists were well versed in the nature of Australian agriculture but it was not until the 1930s and 1940s that scientists and economists alike realised there was an obvious need for trained agricultural economists. In this paper it is argued that the foundations of Australian agricultural economics were laid in the period immediately following the economic upheaval of the Great Depression and the Second World War.

Soil Erosion and Agricultural Sustainability

Science.gov (United States)

Montgomery, D. R.

2009-04-01

Data drawn from a global compilation of studies support the long articulated contention that erosion rates from conventionally plowed agricultural fields greatly exceed rates of soil production, erosion under native vegetation, and long-term geological erosion. Whereas data compiled from around the world show that soil erosion under conventional agriculture exceeds both rates of soil production and geological erosion rates by up to several orders of magnitude, similar global distributions of soil production and geological erosion rates suggest an approximate balance. Net soil erosion rates in conventionally plowed fields on the order of 1 mm/yr can erode typical hillslope soil profiles over centuries to millennia, time-scales comparable to the longevity of major civilizations. Well-documented episodes of soil loss associated with agricultural activities date back to the introduction of erosive agricultural methods in regions around the world, and stratigraphic records of accelerated anthropogenic soil erosion have been recovered from lake, fluvial, and colluvial stratigraphy, as well as truncation of soil stratigraphy (such as truncated A horizons). A broad convergence in the results from studies based on various approaches employed to study ancient soil loss and rates of downstream sedimentation implies that widespread soil loss has accompanied human agricultural intensification in examples drawn from around the world. While a broad range of factors, including climate variability and society-specific social and economic contexts — such as wars or colonial relationships — all naturally influence the longevity of human societies, the ongoing loss of topsoil inferred from studies of soil erosion rates in conventional agricultural systems has obvious long-term implications for agricultural sustainability. Consequently, modern agriculture — and therefore global society — faces a fundamental question over the upcoming centuries. Can an agricultural system

Agricultural pesticides are regularly found in surface waters at concentration levels that raise ecotoxicological concerns. Due to large fluctuations in concentration over time and the potentially high number of pesticides in agricultural watersheds, it is difficult to obtain a comprehensive overview of the actual pollution level. This collaborative project between research and Swiss federal and cantonal authorities aimed for a comprehensive analysis of pesticide pollution in five small agricultural streams to address this knowledge gap. The five rivers are located in catchments (1.5 to 9 km2) with intensive agriculture covering a wide range of crops, such as grains, vegetables, vineyards and orchards. Urban activities and influences are low. Twelve-hour composite samples were collected continuously from March until the end of August with automatic sampling devices, resulting in 360 samples per site. Using precipitation and water level data, we differentiated between discharge events and low-flow periods. Samples taken during dry weather were pooled for the analysis. This procedure resulted in a complete concentration profile over the entire monitoring period covered by 60 samples per site. The analysis, using liquid chromatography coupled to high resolution mass spectrometry (Orbitrap technology), involved a target screening of 248 pesticides including fungicides, herbicides, insecticides, as well as important transformation products. Data on the total number and distribution of pesticides, their detection frequency, crop specific applications and concentration time profiles will be presented. Preliminary results indicate substantial pesticide exposure since at least 20 different compounds were detected in all samples. One sample even contained a mixture of 80 pesticides. The majority of concentrations were in the low ng/L range but concentrations of a few compounds were very high (several micrograms/L) during discharge events as well as during low flow conditions

Full Text Available In recent years, is often heard that Serbia has very favorable conditions for the development of rural tourism. We are constantly talking about the revival of Serbian villages. However, Serbia has a large number of villages ask questions on how to survive and how to improve the conditions of life in them. Since the creation of adequate conditions for life in the country depends on whether it will be and how it continues to evolve. Recommendations of the World Tourism Organization is the development of rural tourism. The reason for this is the favorable geographical position, varied relief, a pleasant climate, rich flora and fauna, interesting history, traditions, folklore ... should be taken of the fact that the Republic of Serbia has a predominantly rural characteristics, because 85% of the territory consists of rural areas inhabited by some 45-55% of the population. The main activity of the population in rural areas is agriculture, where 23% of the working population works in agriculture and generates about 40% of the total gross national income. Between agriculture and rural tourism there are a lot of permeation and solid connections. This cross-sectoral exchange of the common village. Tourism needed agricultural products throughout the year, and agriculture are required consumers. Rural tourism should be the backbone of economic development to raise living standards in the rural community.

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

Directory of Open Access Journals (Sweden)

Menno Mandemaker

2011-06-01

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

Indian agriculture has achieved remarkable success in the food grain production due to inception of 'rainbow revolution', which made the country self-sufficient in food production. Sustainable agriculture (SA) is an ongoing process, in which people take actions leading to development of agriculture that meets their current needs without compromising the ability of future generations to meet their needs. It advocates avoiding all those actions, which reduce the ability of future generations to meet out the present generations. It is based on the optimal interaction between clean environment, healthy economy, and vital society by avoiding trade-off of problems to other regions on to the future. Moreover, sustainable agriculture is the function of people's progress and nature's capacity. In fact, SA commits us to considering the long-term effect and to recognize our place within the ecosystem. It encourages a continuous reflection on the implications of human activity on the ecosystem. Empirical evidences shows that in the race of self-sufficiency in food grain production, we compromised a lot on social and environmental fronts. The aftermath of green revolution is not so sustainable as it showed reverse side too, in the form of environmental degradation and ecological imbalances. Such threats have led to the need for promoting sustainable development in agriculture. Due to several unsustainable activities which resulted in resource degradation in the form of top soil loss, ground water depletion and forest degradation. The average soil loss is estimated to be over 16 tonnes/ha/year. The ground water depletion resulted in several blocks as 'grey blocks' and 'dark blocks'. This happened mainly due to increase in number of tube-wells and free supply of electricity making the cost of pumping water very low. Rate of human induced land degradation is very high. Out of total geographical area of 329.0 million ha, 187 million ha (57.0 %) are reported to have degraded, of

Sustainable agricultural water management across climates

DeVincentis, A.

2016-12-01

Fresh water scarcity is a global problem with local solutions. Agriculture is one of many human systems threatened by water deficits, and faces unique supply, demand, quality, and management challenges as the global climate changes and population grows. Sustainable agricultural water management is paramount to protecting global economies and ecosystems, but requires different approaches based on environmental conditions, social structures, and resource availability. This research compares water used by conservation agriculture in temperate and tropical agroecosystems through data collected from operations growing strawberries, grapes, tomatoes, and pistachios in California and corn and soybeans in Colombia. The highly manipulated hydrologic regime in California has depleted water resources and incited various adaptive management strategies, varying based on crop type and location throughout the state. Operations have to use less water more efficiently, and sometimes that means fallowing land in select groundwater basins. At the opposite end of the spectrum, the largely untouched landscape in the eastern plains of Colombia are rapidly being converted into commercial agricultural operations, with a unique opportunity to manage and plan for agricultural development with sustainability in mind. Although influenced by entirely different climates and economies, there are some similarities in agricultural water management strategies that could be applicable worldwide. Cover crops are a successful management strategy for both agricultural regimes, and moving forward it appears that farmers who work in coordination with their neighbors to plan for optimal production will be most successful in both locations. This research points to the required coordination of agricultural extension services as a critical component to sustainable water use, successful economies, and protected environments.

Agricultural products are obtained within the agricultural holdings, which may be constituted by individual persons, agricultural associations, self – employed persons, individual enterprises, family partnership, agricultural associations, or companies which activate in the vegetal, livestock or mixed section. In order to obtain high quality agricultural products, the owners of agricultural holdings have to make investments from own financing sources, or as a result of accessing European funds, which are dedicated to developing the agricultural sector. The sum of all economical operations made for performing agricultural activities have to be registered in accounting, having the purpose of establishing the value of owned patrimonial elements and of the results obtained by the entity at a certain point.

Although there were not reasons to deplore against major activity release from any of the 110 industrial reactors authorized to operate in US, the nuclear incident that occurred at the Three Mile Island Plant in 1979 urged the public conscience toward the necessity of readiness to cope with events of this type. The personnel of the Emergency Planning Office functioning in the frame of US Department of Agriculture has already participated in around 600 intervention drillings on a federal, local or state scale to plan, test or asses radiological emergency plans or to intervene locally. These exercises allowed acquiring a significant experience in elaborating emergency plans, planning the drillings, working out scenarios and evaluation of the potential impact of accidents from the agricultural point of view. We have also taken part in different international drillings among which the most recent are INEX 1 and RADEX 94. We have found on these occasions that the agricultural problems are essential preoccupations in most of the cases no matter if the context is international, national, local or of state level. The paper poses problems specifically related to milk, fruits and vegetables, soils, meat and meat products. Finally the paper discusses issues like drilling planning, alarm and notification, sampling strategy, access authorizations for farmers, removing of contamination wastes.

Emergy Evaluations of Denmark and Danish Agriculture. Assessing the Limits of Agricultural Systems to Power Society

Energy Technology Data Exchange (ETDEWEB)

Haden, Andrew C. [Swedish Univ. of Agricultural Sciences, Uppsala (Sweden). Dept. of Rural Development Studies

2003-03-01

As the process of industrialization has run its course over the twentieth century, the relative importance of agriculture as an economic activity and a means of cultural sustenance for nations has declined dramatically. In this thesis, a historical ecological-economic perspective offers insights into both the causes and effects of Danish agriculture's decline in economic importance relative to the economy of Denmark as a whole. Emergy evaluations were made of the national economy and agricultural subsystem of Denmark for the years 1936, 1970 and 1999. Emergy is defined as all the available energy that was used in the work of making a product and expressed in units of one type of energy. In total, six separate emergy analyses were performed. By quantifying the emergy requirements of both a national agricultural system and the economy within which this system is nested, the analysis highlights the changing relationship of these two systems over a temporal scale of 63 years. The ecological sustainability of the studied systems is assessed through the calculation of emergy-based indices and ratios. In accordance with emergy theory, ecological sustainability is considered to be a function of the dependence of a system on renewable emergy, the degree to which the system depends on imported emergy, and the overall load that the system places on the environment. The analysis indicates that as the national economy of Denmark evolved to rely more on the use of nonrenewable emergy and on emergy appropriated through trade to stimulate economic activity and to generate wealth, its sustainability declined, and the importance of the Danish agricultural system to the national economy subsided. While the total amount of emergy supporting the economy of Denmark over the period studied increased substantially, the total emergy supporting agriculture remained relatively constant. Furthermore, though the emergy signature and thermodynamic efficiencies of Danish agricultural

Over the coming decades, climate change is likely to pose a major challenge to agriculture; temperatures are rising, rainfall is becoming more variable and extreme weather is becoming a more common event. Researchers and policymakers agree that adapting agriculture to these impacts is a priority for ensuring future food security. Strategies to achieve that in practice tend to focus on modern science. But evidence, both old and new, suggests that the traditional knowledge and crop varieties of indigenous peoples and local communities could prove even more important in adapting agriculture to climate change.

Full Text Available Rudolf Steiner presented his Agriculture Course to a group of 111, farmers and others, at Koberwitz (Kobierzyce, Poland in 1924. Steiner spoke of an agriculture to ‘heal the earth’ and he laid the philosophical and practical underpinnings for such a differentiated agriculture. Biodynamic agriculture is now practiced internationally as a specialist form of organic agriculture. The path from proposal to experimentation, to formalization, to implementation and promulgation played out over a decade and a half following the Course and in the absence of its progenitor. Archival material pertaining to the dissemination of the early printed editions of ‘The Agriculture Course’ reveals that within six years of the Course there was a team of more than 400 individuals of the Agricultural Experimental Circle (AEC, each signed a confidentiality agreement, and located throughout continental Europe, and also in Australia, Britain, Canada, New Zealand, South Africa, and USA. Membership expanded to over 1000 AEC members (with a lower bound estimate of 1144 members who were committed to working collectively towards an evidence based, new and alternative agriculture, ‘for all farmers’, which was to be developed into a ‘suitable for publication’ form. That publication milestone was realized in 1938 with the release of Ehrenfried Pfeiffer’s ‘Bio-Dynamic Farming and Gardening’ which was published simultaneously in at least five languages: Dutch, English, French, German and Italian

Full Text Available In the last decade, organic agriculture in the Central European countries has experienced significant changes, especially in the transitional countries of the Eastern part of the region. This artical studies the position and development of the organic food comparing the agricultures in the western market and former communist countries. It is distinctive for the whole region that there is an interest of the state policy for stimulating the organic agriculture, aspecially in the areas where share is a large number of unemployed people due to the privatisation proces in industry. The organic type of cattle – raising is a represented branch of agriculture while the activities which demand more investments and working hours (horticulture and viticulture are poorly developed. The aim is to bring more biological varieties in the concept of organic agriculture and preserving the naturally protected areas. Therefore the organic agriculture is fregmently introduced as the only acceptable way of the food production in the areas of buffer zones and national parks preserving the autochthonism of the plants and animals in that way encouraging the development of agroeco-tourism.

Adapting Agriculture Platforms for Nutrition: A Case Study of a Participatory, Video-Based Agricultural Extension Platform in India.

Directory of Open Access Journals (Sweden)

Suneetha Kadiyala

Full Text Available Successful integration of nutrition interventions into large-scale development programmes from nutrition-relevant sectors, such as agriculture, can address critical underlying determinants of undernutrition and enhance the coverage and effectiveness of on-going nutrition-specific activities. However, evidence on how this can be done is limited. This study examines the feasibility of delivering maternal, infant, and young child nutrition behaviour change communication through an innovative agricultural extension programme serving nutritionally vulnerable groups in rural India. The existing agriculture programme involves participatory production of low-cost videos promoting best practices and broad dissemination through village-level women's self-help groups. For the nutrition intervention, 10 videos promoting specific maternal, infant, and young child nutrition practices were produced and disseminated in 30 villages. A range of methods was used to collect data, including in-depth interviews with project staff, frontline health workers, and self-help group members and their families; structured observations of mediated video dissemination sessions; nutrition knowledge tests with project staff and self-help group members; and a social network questionnaire to assess diffusion of promoted nutrition messages. We found the nutrition intervention to be well-received by rural communities and viewed as complementary to existing frontline health services. However, compared to agriculture, nutrition content required more time, creativity, and technical support to develop and deliver. Experimentation with promoted nutrition behaviours was high, but sharing of information from the videos with non-viewers was limited. Key lessons learned include the benefits of and need for collaboration with existing health services; continued technical support for implementing partners; engagement with local cultural norms and beliefs; empowerment of women's group members

Agricultural opportunities to mitigate greenhouse gas emissions

Johnson, Jane M.-F.; Franzluebbers, Alan J.; Weyers, Sharon Lachnicht; Reicosky, Donald C.

2007-01-01

Agriculture is a source for three primary greenhouse gases (GHGs): CO 2 , CH 4 , and N 2 O. It can also be a sink for CO 2 through C sequestration into biomass products and soil organic matter. We summarized the literature on GHG emissions and C sequestration, providing a perspective on how agriculture can reduce its GHG burden and how it can help to mitigate GHG emissions through conservation measures. Impacts of agricultural practices and systems on GHG emission are reviewed and potential trade-offs among potential mitigation options are discussed. Conservation practices that help prevent soil erosion, may also sequester soil C and enhance CH 4 consumption. Managing N to match crop needs can reduce N 2 O emission and avoid adverse impacts on water quality. Manipulating animal diet and manure management can reduce CH 4 and N 2 O emission from animal agriculture. All segments of agriculture have management options that can reduce agriculture's environmental footprint. - Management options can be used to reduce agriculture's environmental impacts

Tropical ecosystem conversion to agriculture has caused widespread habitat loss and created fragmented landscapes composed of remnant forest patches embedded in a matrix of agricultural land uses. Non-traditional agricultural export (NTAE) crops such as pineapple are rapidly replacing multiuse landscapes characterized by a diverse matrix of pasture and smallholder crops with intensive, large-scale, monoculture plantations. Using an interdisciplinary approach, we examine the coupled social and ecological implications of agricultural intensification Guided by frameworks from political economy, landscape ecology and landscape genetics we: (1) describe the social and economic implications of pineapple expansion, specifically the concentration of land, labor and financial resources, (2) quantify pineapple cultivation's spatial characteristics, and (3) assess the effects of pineapple expansion on surrounding forest ecosystems, on the agricultural matrix and on biodiversity conservation. Our results indicate that pineapple production concentrates land, labor, and financial resources, which has a homogenizing effect on the agricultural economy in the study region. This constrains farm-based livelihoods, with larger implications for food security and agricultural diversity. Landscape ecology and genetics analyses further reveal how pineapple production simplifies and homogenizes the agricultural matrix between forest patches, which increase the genetic structure and reduce the genetic diversity of Symphonia globulifera a forest understory tree species. To offset the effects of agricultural intensification on social and environmental systems, we recommend developing landscape level land use planning capacity. Furthermore, agricultural and conservation policy reform is needed to promote landscape heterogeneity and economic diversity within the agricultural sector. Our interdisciplinary research provides a detailed examination of the social and ecological impacts of

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

Agriculture and environmental pollution

International Nuclear Information System (INIS)

Hafiz, A.

1999-01-01

Agriculture came into existence about 15,000 years ago and passed through different stages of food gathering, hunting, hoe culture and sedentary agriculture followed by modem agriculture. It began simultaneously in five world centers concentrating on different crops, most suited to those areas. It was also effected by changes in climate influenced by temperature, drought and magnitude of precipitation, which determined the distribution of populations and occupation of the people. With the increase in population the need for food also progressively increased, necessitating introduction of modern agriculture to enhance production. The indiscriminate and faulty use of advanced technology has added its share in the, destruction of environment. The two approaches that contributed to this were horizontal wand vertical expansion. The former results in deforestation, desertification, soil erosion, land salting and water logging as well as the frequent occurrence of droughts and famines, the latter destroyed soil structure and fertility through decreased microbial populations, fish culture, wildlife and bird sanctuaries, in addition to hazards in human beings and fauna. The real culprit of this global devastation is the high population growth rate, which needs to be contained at safer levels, coupled with sensible use of inputs to produce needed quantities of food and fiber.

Agricultural growth, the status of women, and fertility.

Science.gov (United States)

Whittington, L A; Stapleton, D C

1995-08-01

This study tests the hypothesis that fertility is affected differently by economic growth depending upon the specific sector (agriculture, manufacturing, heavy industry, and services) where growth occurred. The hypothesis is that fertility responses are not identical across sectors. The sample includes 51 World Bank member countries in varying stages of development. The econometric model pertains to 1965-88 and the percentage change in the total fertility rate (TFR). During the study period the average TFR declined by over 22%, but the extent of change varied by country and included, for instance, countries such as Ethiopia that experienced fertility increases from 5.8 to 6.5. Hong Kong's TFR declined by 66% from 4.7 to 1.6. Analysis included measures of changes in gross domestic product (GDP) for each of the four sectors and change in real per capita exports in agricultural commodities, resources, and manufactured products. Changes in educational status and changes in infant mortality were also included in some models. There were mixed results for the impact of total GDP. Sectoral analysis shows a positive, small significant impact on TFR from changes in the GDP per capita in agriculture (domestic and export products), and a negative, small significant impact from manufacturing growth. Heavy industry and services produced insignificant impact. In the model with only domestic consumption, results show a stronger coefficient and continued significance for agricultural productivity, agricultural exports, and manufacturing changes per capita. Manufacturing exports produced a negative, insignificant impact. The null hypothesis is rejected only in models comparing aggregate GDP in agriculture and manufacturing industries plus control variables (excluding heavy industry and services). Only secondary education was a negative, significant determinant of fertility. Infant mortality was insignificant when sectoral growth and education were included in the model. The evidence

Application of Systematic Approach to the Study of Financial and Credit Infrastructure of Agriculture

Directory of Open Access Journals (Sweden)

Aleksandr Vladimirovich Dorzhdeev

2015-12-01

Full Text Available The increasing value of development of financial and credit infrastructure of agriculture in reproduction activity of agricultural producers is caused by the need of continuous receipt of funds for financing the requirements of agriculture and limited opportunities of selffinancing as a result of rather high capital intensity at rather low level of profitability. The systematic approach to research of financial and credit infrastructure of agriculture assumes its consideration as a set of the interconnected and interdependent subsystems and their elements focused on performance of certain functions. The use of systematic approach deepens complete theoretical ideas about the financial and credit infrastructure of agriculture. In the present article the essence of financial and credit infrastructure of agriculture in the points of view of functional and institutional aspects is opened, its subsystems are characterized, their functions and elements are defined by the authors. The study of the systemic features of market infrastructure allowed the authors to reveal the signs peculiar to financial and credit infrastructure of agricultural sector.

Sustainable intensification in agricultural systems.

Science.gov (United States)

Pretty, Jules; Bharucha, Zareen Pervez

2014-12-01

Agricultural systems are amended ecosystems with a variety of properties. Modern agroecosystems have tended towards high through-flow systems, with energy supplied by fossil fuels directed out of the system (either deliberately for harvests or accidentally through side effects). In the coming decades, resource constraints over water, soil, biodiversity and land will affect agricultural systems. Sustainable agroecosystems are those tending to have a positive impact on natural, social and human capital, while unsustainable systems feed back to deplete these assets, leaving fewer for the future. Sustainable intensification (SI) is defined as a process or system where agricultural yields are increased without adverse environmental impact and without the conversion of additional non-agricultural land. The concept does not articulate or privilege any particular vision or method of agricultural production. Rather, it emphasizes ends rather than means, and does not pre-determine technologies, species mix or particular design components. The combination of the terms 'sustainable' and 'intensification' is an attempt to indicate that desirable outcomes around both more food and improved environmental goods and services could be achieved by a variety of means. Nonetheless, it remains controversial to some. This review analyses recent evidence of the impacts of SI in both developing and industrialized countries, and demonstrates that both yield and natural capital dividends can occur. The review begins with analysis of the emergence of combined agricultural-environmental systems, the environmental and social outcomes of recent agricultural revolutions, and analyses the challenges for food production this century as populations grow and consumption patterns change. Emergent criticisms are highlighted, and the positive impacts of SI on food outputs and renewable capital assets detailed. It concludes with observations on policies and incentives necessary for the wider adoption of

Winter, Jonathan M.; Lopez, Jose R.; Ruane, Alexander C.; Young, Charles A.; Scanlon, Bridget R.; Rosenzweig, Cynthia

2017-01-01

Globally, irrigated agriculture is both essential for food production and the largest user of water. A major challenge for hydrologic and agricultural research communities is assessing the sustainability of irrigated croplands under climate variability and change. Simulations of irrigated croplands generally lack key interactions between water supply, water distribution, and agricultural water demand. In this article, we explore the critical interface between water resources and agriculture by motivating, developing, and illustrating the application of an integrated modeling framework to advance simulations of irrigated croplands. We motivate the framework by examining historical dynamics of irrigation water withdrawals in the United States and quantitatively reviewing previous modeling studies of irrigated croplands with a focus on representations of water supply, agricultural water demand, and impacts on crop yields when water demand exceeds water supply. We then describe the integrated modeling framework for simulating irrigated croplands, which links trends and scenarios with water supply, water allocation, and agricultural water demand. Finally, we provide examples of efforts that leverage the framework to improve simulations of irrigated croplands as well as identify opportunities for interventions that increase agricultural productivity, resiliency, and sustainability.

Analysis of Changes in Land Use Patterns Pursuant to the Conversion of Agricultural Land to Non-Agricultural Use in the Context of the Sustainable Development of the Malopolska Region

Directory of Open Access Journals (Sweden)

Malgorzata Busko

2018-01-01

Full Text Available This research paper presents the results of analyses that address the direction in which the issue of land use in Malopolska has been heading in recent years. The authors formulated the thesis that changes occurring in the use of agricultural land are advanced and, despite its legal protection, this land is continuously subjected to permanent conversion to non-agricultural use year by year. Verification of the thesis was carried out using taxonomic analyses. As a result, it was proven that as much as 68% of the land converted to non-agricultural use in the study period was earmarked for residential use. Importantly, as much as 19% of these areas are of the best quality classes, i.e., classes I and II, which account for a mere 7% of all agricultural land in Malopolska. Another 79% of the converted agricultural land belonged to the mid class, i.e., class III, which—at the time of writing—represents only 26% in the Malopolska Province. This data demonstrates that the best lands of the Malopolska Province, which belonged to classes I, II and III (i.e., top quality arable soils, were irreversibly degraded by their conversion to non-agricultural use. The paper proposes systemic solutions supporting the decision-making process of administrative bodies aimed at agricultural land protection.

Full Text Available Normative pecuniary valuation of land belongs to important economic regulators of land relations in Ukraine. Indicators of monetary valuation of land plots are used to determine the size of the land tax, the State duty at exchange, inheritance and the donation of land rent for land plots of the state and communal property, loss of agricultural and forestry production, as well as in the development of indicators and economic mechanisms to stimulate rational use and protection of lands. Normative monetary valuation of agricultural land is defined according to the standards of capitalized rent income on land for agricultural purposes and indicators of soils bonitet by drafting evaluation scales of agroindustrial groups of soils in natural agricultural areas. Index of standard capitalized rent on income reflects the profitability of a business. The soil differences appear on soil maps and they are the main target of the regulatory evaluation. The main source of information about the soil cover of agricultural land should actually be made by Derzhgeocadastr archives and its subordinate State enterprises according to the results of standard evaluation of a single agricultural land plot under the territorial authority of Derzhgeocadastr through administrative services at the location of the land. An extract from the technical documentation about the regulatory assessments of land must be published in time not exceeding three working days from the date of receipt of the corresponding application. The introduction of new methodological approach to the standard evaluation of agricultural lands involves the simplification of access of landowners and land users to data evaluation, based on possible continuous evaluation of administrative districts and providing information about the assessment of the particular land plot in the form of extract from the technical documentation of the standard evaluation, which will be determined on the basis of standard

Srinivasan, S. P.; Sorna Shanthi, D.; Anand, Aashish V.

2017-06-01

Re-structuring the practices of traditional inventory management is becoming more essential to optimize the supply chain transparency and accuracy of agricultural produce. A flexible and transparent inventory management system is becoming the need of any agricultural commodity. It was noticed that the major setback for the farmers who are the suppliers of the farm produce is due to poor supply chain integration. The recent advent technologies and IT explosion can bring up a greater impact in the process of storing, tracking, distributing and monitoring perishable agriculture produce of day to day life. The primary focus of this paper is to integrate IoT into inventory management and other inbound logistics management of agriculture produce. The unique features of agricultural produce like a prediction of supply, demand, the location of warehouses, distribution and tracking of inventory can be integrated through IoT. This paper proposes a conceptual framework for inventory management transparency involved in the supply chain of agriculture produce.

How is nutrition linked to agriculture and education?

Directory of Open Access Journals (Sweden)

Sayed Mohammad Naim Khalid

2016-02-01

Full Text Available Agricultural development is now expected to proceed in a way that maximizes opportunities to improve health and nutrition. Accordingly, the term “nutrition-education-agriculture linkages” describes the set of relationships that shows the mutual dependence of nutrition, education and agriculture. Changes in nutrition or education status are expected to affect agricultural production; conversely changes in the agricultural sector can have significant effects on individual health and nutritional status. Professionals in are trained in nutrition or agriculture, but very few will be trained in both. It is therefore difficult to begin discussions on nutrition-focused agricultural programs and policies. How do we begin to identify these linked outcomes? And how do we begin to think about ways to impact factors that are outside of our sector of expertise? This paper provides a simple framework for thinking critically about nutrition, education and agriculture linkages. The purpose is to help readers identify the linkages of greatest importance to their goals and to begin thinking about how to take steps toward integrating programs more effectively.

Post-Chernobyl scientific perspectives: Agricultural countermeasures

International Nuclear Information System (INIS)

Richards, J.I.; Hance, R.J.

1996-01-01

One of the lessons of Chernobyl is that farming is vulnerable to the effects of a nuclear accident hundreds, even thousands, of miles away from the site. Therefore plans are needed for countermeasures that can reduce contamination of agricultural produce, regardless of whether or not a country has its own nuclear programme. The plans need to specify radiation levels for foods and feedstuffs at which intervention is necessary and to include a range of countermeasures to be taken to protect agriculture under a range of possible post-accident situations. The FAO/WHO Codes Alimentarius Commission has developed international standards for radionuclides contamination to be applied to food moving in international trade. The intervention levels are based on a number of conservative assumptions to be confident that there will be essentially no effect over a lifetime of exposure. An important purpose of agricultural countermeasures is to maximize the quantity of food produced which passes intervention criteria. The present report discusses how the Joint FAO/IAEA programme on nuclear techniques in food and agriculture has approached agricultural countermeasures

Ensuring adequate food supplies to a large and increasing population continues to be the key challenge for China. Given the increasing integration of China within global markets for agricultural products, this issue is of considerable significance for global food security. Over the last 50 years, China has increased the production of its staple crops mainly by increasing yield per unit land area. However, this has largely been achieved through inappropriate agricultural practices, which have caused environmental degradation, with deleterious consequences for future agricultural productivity. Hence, there is now a pressing need to intensify agriculture in China using practices that are environmentally and economically sustainable. Given the dynamic nature of crops over space and time, the use of remote sensing technology has proven to be a valuable asset providing end-users in many countries with information to guide sustainable agricultural practices. Recently, the field has experienced considerable technological advancements reflected in the availability of 'hyper-sensing' (high spectral, spatial and temporal) satellite imagery useful for monitoring, modelling and mapping of agricultural crops. However, there still remains a significant challenge in fully exploiting such technologies for addressing agricultural problems in China. This review paper evaluates the potential contributions of satellite 'hyper-sensing' to agriculture in China and identifies the opportunities and challenges for future work. We perform a critical evaluation of current capabilities in satellite 'hyper-sensing' in agriculture with an emphasis on Chinese sensors. Our analysis draws on a series of in-depth examples based on recent and on-going projects in China that are developing 'hyper-sensing' approaches for (i) measuring crop phenology parameters and predicting yields; (ii) specifying crop fertiliser requirements; (iii) optimising management responses to abiotic and biotic stress in crops

Agriculture requires continuous supply of inputs to production, while providing final or intermediate outputs or products (food, forage, industrial uses, etc.). Government and other economic agents are interested in the continuity of this process and make decisions based on the available information about current conditions within the agriculture area. From a government point of view, it is important that the input-output chain in agriculture for a given area be enhanced in time, while any possible abrupt disruption be minimized or be constrained within the variation tolerance of the input-output chain. The stability of the exchange of inputs and outputs becomes of even more important in disaster-affected zones, where government programs will look for restoring the area to equal or enhanced social and economical conditions before the occurrence of the disaster. From an economical perspective, potential and existing input providers require up-to-date, precise information of the agriculture area to determine present and future inputs and stock amounts. From another side, agriculture output acquirers might want to apply their own criteria to sort out present and future providers (farmers or irrigators) based on the management done during the irrigation season. In the last 20 years geospatial information has become available for large areas in the globe, providing accurate, unbiased historical records of actual agriculture conditions at individual land units for small and large agricultural areas. This data, adequately processed and stored in any database format, can provide invaluable information for government and economic interests. Despite the availability of the geospatial imagery records, limited or no geospatial-based information about past and current farming conditions at the level of individual land units exists for many agricultural areas in the world. The absence of this information challenges the work of policy makers to evaluate previous or current

Working Conditions of Agricultural Workers: A Reflection of Socio-economic Status

B.R.K. Sinha

2010-11-01

Full Text Available Working conditions of agricultural workers, like industrial, are one of the burning issues in a developing region. It is related to agricultural activities of the workers and their socio-economic status. Working conditions may be both favourable and unfavourable. Those working conditions which are unfavourable to health may be considered as occupational hazards or as a part of occupational environment. It is generally observed that a large section of the agricultural workers remains engaged in agricultural practices at the time of hunger, thirst, pregnancy (women and even despite their unpleasant state of health, both mental and physical. They also continue to work for more than the prescribed standard hours and also having half-fed. These are not positive or favourable working conditions to their health as they normally cause general weakness, fatigue, stomach disorder, dizziness, headache, loss of energy and some other similar physical, mental and psychological problems. The major driving forces behind as such adverse working conditions and its consequences are the pressure of work, pressure of land owners and of timely completion of works, shortage of manpower, psychological attitude, ignorance, weather constraints, poverty, illiteracy, lack of work related health awareness, lower social and economic status, etc. Such forces compel the workers to be engaged in their agricultural practices under the above circumstance. Adverse working conditions of agricultural workers vary widely with reference to space, time, activities, demographics, society, economy and consequently affect both the mental and physical, social and psychological conditions of the agricultural workers. Persons in varying number in the age groups from 15-34 and 35-49 to 60 & + year were reported working under different types of undesirable working conditions. The people from the S.C. and S.T. categories are the major sufferers as most of them continue their work during

Climate-smart agriculture: possible roles of agricultural universities in a strengthened Norwegian climate change engagement in Africa

2012-02-15

The recent rise in the number of food insecure people in the world, coupled with incidences of crop failure due to adverse weather, have made world leaders increasingly aware that future climate change may severely limit our ability to feed the growing population towards 2050. So far, in addition to industrial emission control, Norwegian efforts to restrict climate change have focused on mitigation through forest protection (REDD+) and clean energy (Energy+). A third area of attention is climate-smart agriculture. Producing food in a more 'climate smart' way is seen as having three advantages: 1) Providing food for an increasing population, 2) maintaining food production under a changing climate, and 3) reducing greenhouse gas emission from agriculture while absorbing carbon in vegetation and soil. This report explores how Norway can support Africa's efforts to make agriculture more climate-smart through support to African universities.Among the three benefits of climate-smart agriculture, African farmers will be most inclined to focus on the two first, the production increase and the adaptation. Mitigation may require external support. African leaders are in the forefront of developing policies and institutional arrangements for climate-smart agriculture. Among other initiatives, the Comprehensive Africa Agriculture Development Programme under the African Union is in the process of preparing member states for substantial investments in agriculture. Capacity building and the generation of new knowledge are essential for the achievement of climate-smart agriculture. Given the long history of Norwegian support to agricultural research and higher agricultural education in several African countries, Norway can, without doubt, make significant contributions to African food security, now and in the future.Norwegian support to climate-smart agriculture can be based on its experience with REDD+ and Energy+ initiatives.

Exploring Agricultural Drainage's Influence on Wetland and ...

Science.gov (United States)

Artificial agricultural drainage (i.e. surface ditches or subsurface tile) is an important agricultural management tool. Artificial drainage allows for timely fieldwork and adequate root aeration, resulting in greater crop yields for farmers. This practice is widespread throughout many regions of the United States and the network of artificial drainage is especially extensive in flat, poorly-drained regions like the glaciated Midwest. While beneficial for crop yields, agricultural drains often empty into streams within the natural drainage system. The increased network connectivity may lead to greater contributing area for watersheds, altered hydrology and increased conveyance of pollutants into natural water bodies. While studies and models at broader scales have implicated artificial drainage as an important driver of hydrological shifts and eutrophication, the actual spatial extent of artificial drainage is poorly known. Consequently, metrics of wetland and watershed connectivity within agricultural regions often fail to explicitly include artificial drainage. We use recent agricultural census data, soil drainage data, and land cover data to create estimates of potential agricultural drainage across the United States. We estimate that agricultural drainage in the US is greater than 31 million hectares and is concentrated in the upper Midwest Corn Belt, covering greater than 50% of available land for 114 counties. Estimated drainage values for numerous countie

Khan, S.M.L

2005-01-01

There is agro-pastoral farming system prevalent in mountainous and sub-mountainous areas of Himalayan region including Azad Jammu and Kashmir. As such, Agriculture Sector includes Crop-husbandry, livestock farming and forestry in its ambit. There are varied forms of land uses, like crop farming, forestry, animal husbandry, fisheries, wildlife conservation etc. Therefore, the paper attempts to spotlight the interplay of these land uses with respect to the environment in general with specific reference to AJK and other mountainous and sub- mountainous regions of Northern Pakistan. Agricultural activities have both negative and beneficial effects on the environment. The negative effects in the forms of physical degradation of the soil due to agriculture are: soil erosion, desertification, water logging and salinity and soil compaction. The land use practices such as overgrazing, deforestation and some cultivation practices, removal of vegetative cover or hedgerows, lack of proper drainage outlets, accentuate these problems. The improper management of water use and sometimes excessive mechanization and Ploughing further aggravates problem of physical degradation of the soil. The chemical degradation, as a result of agricultural practices, include acidification, Salinization, contamination caused by pesticides and insecticides and resultantly water and air pollution, and loss of habitats and biodiversity. Further negative effects emerging out of agricultural practices are greenhouse gas emissions, nutrient losses and lowering of humus content, which makes soil susceptible to compaction and erosion. The beneficial environmental effects emanating from the use of best agricultural management practices and integrated farming systems are protection of soil fertility and stability, prevention of excessive run offs. It also provides habitats for varied forms of flora and fauna, reduce the emission of carbon dioxide (CO/sub 2)/ and reduce the incidence and severity of natural

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

Science.gov (United States)

Cockell, C. S.

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

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

As the global population continues to grow and become more wealthy, the amount of food humanity consumes should also grow, particularly in low income countries that are currently consuming significantly less per capita than is optimal. Reducing yield gaps in low income regions can increase overall agricultural production and pull populations conducting subsistence agriculture in rural areas out of poverty. Investment in the transformation of agricultural value chain to include low income farmers can have significant positive impacts on communities and individuals participating, as well as the resilience of the food system itself. A major obstacle to improving the effectiveness of policies and interventions in the rural agriculture sector is a lack of information about the socio-economic, agricultural production and environmental conditions experienced by farmers as they participate in agriculture. There is a significant lack of high quality statistics that can be used to develop effective agricultural development programs. In today's world of online mapping software, accurate global positioning systems that allow instant, affordable location retrieval and growing mobile connectivity, what is needed is community- or even field-level information. Given the enormous geographic, economic and cultural diversity of even small countries, why settle for national statistics? The kind of information that is needed is at the field and farmer level, not the country level. This paper reviews ways geospatial and information technology can be used to generate farmer-specific information across all countries participating in agriculture.

Effects of climate change on US agriculture; Les effets du changement climatique sur l'agriculture americaine

Guillet, L

2007-08-15

The USA are a major producer of food and fiber products in the world. The US agriculture represents more than 25% of the world trades of wheat, corn, soy and cotton. The cultivated surfaces and the pasture lands represent 210 million Ha (17% of the US territory) and 300 million Ha (26% of the US territory), respectively. The agricultural production represents less than 2% of the US GDP, put the agriculture products make about 5% of the US exports. The climate change may have some impacts on the overall agriculture industry, from the plant growth to the conditions of competition on international markets. In 2001, the US global change research program, published an evaluation report about the potential consequences of the climate change on the US agriculture. The conclusions of the panel of experts, based on climate, cultivation and economical models, was that the CO{sub 2} levels and climate changes of the 21. century would have no negative impact on the US agriculture. The average effects, on the contrary, would be rather positive, depending on the type of culture and on the region considered. Today, the experts have entertained lot of doubts about the 2001 forecasts: the fertilizing effect of CO{sub 2} is more and more criticized and an efficient supply of water appears as seriously compromised for many regions. Experts stress also on the lack of consideration for extreme climatic events, and for crop vermin and diseases. This document reanalyzes the conclusions of the 2001 report in the light of the works carried out more recently at the Agriculture Research Service (ARS). The proceedings of expert's interviews are attached in appendixes. (J.S.)

World food and agriculture: outlook for the medium and longer term.

Science.gov (United States)

Alexandratos, N

1999-05-25

The world has been making progress in improving food security, as measured by the per person availability of food for direct human consumption. However, progress has been very uneven, and many developing countries have failed to participate in such progress. In some countries, the food security situation is today worse than 20 years ago. The persistence of food insecurity does not reflect so much a lack of capacity of the world as a whole to increase food production to whatever level would be required for everyone to have consumption levels assuring satisfactory nutrition. The world already produces sufficient food. The undernourished and the food-insecure persons are in these conditions because they are poor in terms of income with which to purchase food or in terms of access to agricultural resources, education, technology, infrastructure, credit, etc., to produce their own food. Economic development failures account for the persistence of poverty and food insecurity. In the majority of countries with severe food-security problems, the greatest part of the poor and food-insecure population depend greatly on local agriculture for a living. In such cases, development failures are often tantamount to failures of agricultural development. Development of agriculture is seen as the first crucial step toward broader development, reduction of poverty and food insecurity, and eventually freedom from excessive economic dependence on poor agricultural resources. Projections indicate that progress would continue, but at a pace and pattern that would be insufficient for the incidence of undernutrition to be reduced significantly in the medium-term future. As in the past, world agricultural production is likely to keep up with, and perhaps tend to exceed, the growth of the effective demand for food. The problem will continue to be one of persistence of poverty, leading to growth of the effective demand for food on the part of the poor that would fall short of that required for

2017-01-01

Maintaining the long-term sustainability of human and natural systems across agricultural landscapes requires an integrated, systematic monitoring system that can track crop productivity and the impacts of agricultural intensification on natural resources. This study presents the design and practical implementation of a monitoring framework that combines satellite observations with ground-based biophysical measurements and household surveys to provide metrics on ecosystem services and agricultural production at multiple spatial scales, reaching from individual households and plots owned by smallholder farmers to 100-km 2 landscapes. We developed a set of protocols for monitoring and analyzing ecological and agricultural household parameters within two 10 × 10-km landscapes in Rwanda, including soil fertility, crop yield, water availability, and fuelwood sustainability. Initial results suggest providing households that rely on rainfall for crop irrigation with timely climate information and improved technical inputs pre-harvest could help increase crop productivity in the short term. The value of the monitoring system is discussed as an effective tool for establishing a baseline of ecosystem services and agriculture before further change in land use and climate, identifying limitations in crop production and soil fertility, and evaluating food security, economic development, and environmental sustainability goals set forth by the Rwandan government.

Managing Artificially Drained Low-Gradient Agricultural Headwaters for Enhanced Ecosystem Functions

Science.gov (United States)

Pierce, Samuel C.; Kröger, Robert; Pezeshki, Reza

2012-01-01

Large tracts of lowlands have been drained to expand extensive agriculture into areas that were historically categorized as wasteland. This expansion in agriculture necessarily coincided with changes in ecosystem structure, biodiversity, and nutrient cycling. These changes have impacted not only the landscapes in which they occurred, but also larger water bodies receiving runoff from drained land. New approaches must append current efforts toward land conservation and restoration, as the continuing impacts to receiving waters is an issue of major environmental concern. One of these approaches is agricultural drainage management. This article reviews how this approach differs from traditional conservation efforts, the specific practices of drainage management and the current state of knowledge on the ecology of drainage ditches. A bottom-up approach is utilized, examining the effects of stochastic hydrology and anthropogenic disturbance on primary production and diversity of primary producers, with special regard given to how management can affect establishment of macrophytes and how macrophytes in agricultural landscapes alter their environment in ways that can serve to mitigate non-point source pollution and promote biodiversity in receiving waters.

This article reviews how this approach differs from traditional conservation efforts, the specific practices of drainage management and the current state of knowledge on the ecology of drainage ditches. A bottom-up approach is utilized, examining the effects of stochastic hydrology and anthropogenic disturbance on primary production and diversity of primary producers, with special regard given to how management can affect establishment of macrophytes and how macrophytes in agricultural landscapes alter their environment in ways that can serve to mitigate non-point source pollution and promote biodiversity in receiving waters.

Land conversion, forest cutting, urban growth, agricultural expansion, take place at an unprecedented rate and scale such that they have a strong economic and environmental impact. Understanding and measuring dynamics becomes a prerequisite for companies, governments, agencies, NGO's, research institutes and society in general. In many cases the temporal frequency of the information is a requirement to detect phenomena that can occur within a few days and at a certain geographic scale. For example frequent updates on crop condition and projected production are needed to stabilise agricultural markets. Large initiatives such as the GEOGLAM AMIS (Group on Earth Observations Global Agricultural Monitoring - Agricultural Market Information System) respond to this increased need. Observations over large areas are available through satellites, however, the following challenges remain: • obtaining frequent and consistent observations at sufficient level of detail to identify spatial phenomena. At present, no single mission is capable of providing near daily information of any place in the world at scales appropriate to detect land cover/use changes in a consistent manner. • the need for a historical reference. For agricultural monitoring and early warning purposes the comparison of the actual data with a historical reference is of the utmost importance. The PROBA-V mission is an important attempt to overcome these challenges. From its design and within the GIO-Global Land component a lot of work has been done to ensure the consistency between the PROBA-V data and the 15 years historical archive of SPOT-VEGETATION. In this respect PROBA-V observations are comparable with the SPOT-VEGETATION historical baseline and will therefore ensure the continuation of the standard agricultural monitoring products. Next to this integration with the historical archive, PROBA -V also provides an increase in spatial resolution from 1km to 300m and even 100m. The latter ensures a global

During the 40th Annual Meeting of The Toxicology Forum, the current and potential future science, regulations, and politics of agricultural biotechnology were presented and discussed. The meeting session described herein focused on the technology of RNA interference (RNAi) in agriculture. The general process by which RNAi works, currently registered RNAi-based plant traits, example RNAi-based traits in development, potential use of double stranded RNA (dsRNA) as topically applied pesticide active ingredients, research related to the safety of RNAi, biological barriers to ingested dsRNA, recent regulatory RNAi science reviews, and regulatory considerations related to the use of RNAi in agriculture were discussed. Participants generally agreed that the current regulatory framework is robust and appropriate for evaluating the safety of RNAi employed in agricultural biotechnology and were also supportive of the use of RNAi to develop improved crop traits. However, as with any emerging technology, the potential range of future products, potential future regulatory frameworks, and public acceptance of the technology will continue to evolve. As such, continuing dialogue was encouraged to promote education of consumers and science-based regulations. Copyright © 2015 Elsevier Inc. All rights reserved.

The agricultural and the democratic transitions

DEFF Research Database (Denmark)

Gundlach, Erich; Paldam, Martin

Long-run development (in income) causes a large fall in the share of agriculture commonly known as the agricultural transition. We confirm that this conventional wisdom is strongly supported by the data. Long-run development (in income) also causes a large increase in democracy known...... as the democratic transition. Elsewhere we have shown that it is almost as strong as the agricultural transition. Recently, a method has been presented to weed out spuriousness. It makes the democratic transition go away by turning income insignificant, when it is supplemented by a set of formal controls. We show...... that the same method makes the agricultural transition go away as well. Hence, it seems to be a method that kills far too much, as suggested by the subtitle. This suggestion leads to a discussion of the very meaning of long-run causality....

Labor and Employment in Brazilian Northeastern Agriculture: a look at the 2004-2014 period

Directory of Open Access Journals (Sweden)

Otavio Valentim Balsadi

Full Text Available Abstract: The labor market in the Brazilian Northeastern agriculture is characterized by many forms of occupation, ranging from the salaried work to the various forms of family work. In a heterogeneous and diverse agriculture, there is a complex labor market, with changes in recent times. Therefore, it is necessary to keep a watchful eye on important structural features. As a result, this paper aims to analyze the main aspects related to work and employment relations in the Brazilian Northeastern agriculture in the 2004-2014 period. The sources of information are special tabulations from the National Survey by Household Sample (PNAD, conducted by the Brazilian Institute of Geography and Statistics (IBGE. The results pointed to a continuing decline in Northeastern PEA (Economically Active Population occupied in agriculture, partially offset by the growth of Northeastern rural residents occupied in non-agricultural activities, in addition to the people occupied in self-consumption production. Women and young people were the ones who mostly left the agricultural activities, reinforcing the “ageing” process of the occupied PEA. The crops with the largest reduction in the occupied in agricultural PEA were: cassava, rice, coffee, banana, sugarcane, cocoa, vegetables and fruits. On the other hand, the number of occupied people increased in: corn and grape cultivation, services for agriculture, swine and poultry farming and integrated agricultural and livestock production systems. An increase in schooling of the occupied PEA was registered, though it is still below the national average.

Weather extremes could affect agriculture

Science.gov (United States)

Balcerak, Ernie

2012-05-01

As Earth's climate warms, agricultural producers will need to adapt. Changes, especially increases in extreme events, are already having an impact on food production, according to speakers at a 1 May session on agriculture and food security at the AGU Science Policy Conference. Christopher Field, director of the Department of Global Ecology at the Carnegie Institution for Science of Washington, D. C., pointed out the complex factors that come into play in understanding food security, including spatially varying controls and stresses, incomplete models, and the potential for threshold responses. Factors that are likely to cause problems include increasing population; increasing preference for meat, which needs more land and energy inputs to produce; climate change; and increasing use of agricultural lands for biomass energy.

Impacts of sand and dust storms on agriculture and potential agricultural applications of a SDSWS

International Nuclear Information System (INIS)

Stefanski, R; Sivakumar, M V K

2009-01-01

This paper will give an overview of the various impacts of sand and dust storms on agriculture and then address the potential applications of a Sand and Dust Storm Warning System (SDSWS) for agricultural users. Sand and dust storms have many negative impacts on the agricultural sector including: reducing crop yields by burial of seedlings under sand deposits, the loss of plant tissue and reduced photosynthetic activity as a result of sandblasting, delaying plant development, increasing end-of-season drought risk, causing injury and reduced productivity of livestock, increasing soil erosion and accelerating the process of land degradation and desertification, filling up irrigation canals with sediments, covering transportation routes, affecting water quality of rivers and streams, and affecting air quality. One positive impact is the fertilization of soil minerals to terrestrial ecosystems. There are several potential agricultural applications of a SDSWS. The first is to alert agricultural communities farmers to take preventive action in the near-term such as harvesting maturing crops (vegetables, grain), sheltering livestock, and strengthening infrastructure (houses, roads, grain storage) for the storm. Also, the products of a SDSWS could be used in for monitoring potential locust movement and post-storm crop damage assessments. An archive of SDSWS products (movement, amount of sand and dust) could be used in researching plant and animal pathogen movement and the relationship of sand and dust storms to disease outbreaks and in developing improved soil erosion and land degradation models.

Landscape diversity and the resilience of agricultural returns: a portfolio analysis of land-use patterns and economic returns from lowland agriculture

Directory of Open Access Journals (Sweden)

Abson David J

2013-01-01

Full Text Available Abstract Background Conventional agriculture is increasingly based on highly specialized, highly productive farms. It has been suggested that 1 this specialization leads to farms that lack resilience to changing market and environmental conditions; and 2 that by decreasing agricultural diversity, the resilience of the farming system also decreases. Methods We used agricultural gross margin (GM forecasts from 1966 to 2010 and remote sensing data from agricultural landscapes in the lowland UK, in conjunction with modern portfolio theory, to test the hypothesis that decreasing land-use diversity results in landscapes that provide higher, but more volatile, economic returns. We considered the role of spatial scale on the expected levels of volatility and resilience of agricultural returns. Results We found that: 1 there was a strong linear trade-off between expected GMs and the expected volatility of those GMs in real lowland agricultural landscapes in the UK; 2 land-use diversification was negatively correlated with expected GMs from agriculture, and positively correlated with decreasing expected volatility in GMs; 3 the resilience of agricultural returns was positively correlated with the diversity of agricultural land use, and the resilience of agricultural returns rose quickly with increased land-holding size at small spatial extents, but this effect diminished after landholdings reached 12,000 hectares. Conclusions Land-use diversity may have an important role in ensuring resilient agricultural returns in the face of uncertain market and environmental conditions, and land-holding size plays a pivotal role in determining the relationships between resilience and returns at a landscape scale. Creating finer-grained land-use patterns based on pre-existing local land uses may increase the resilience of individual farms, while maintaining aggregate yield across landscapes.

Changing climate will have adverse effects on food production, food distribution, infrastructure, land availability for agriculture, and livelihood assets and opportunities in rural and urban areas. Adapting food systems to both enhance food security for the poor and to prevent the future negative impacts of climate change will require attention to more than just agricultural production. Food security can only be ensured and enhanced through a range of interventions across different agricultural systems and along the associated value chains, from production to distribution and allocation. The current efforts to get agriculture into the global climate policy framework after the expiry of the Kyoto Protocol emphasises mitigation. Adaptation is an equally important objective in a world that cannot avoid climate change any more because of already accumulated greenhouse gases. In developing countries, adaptation is the primary concern due to their vulnerability to climate change and high dependence on weather-dependent agricultural systems. A complete response to climate change that integrates agriculture should therefore pursue both agricultural mitigation and adaptation. In order to plan for adaptation effectively, policy makers need reliable information from developing countries on the nature of adaptation, its costs and how these are related to ongoing efforts to develop the agriculture sector and food systems of developing countries. This study set out to inform climate policy development by analysing agricultural adaptation in developing countries using a combination of desk studies and country case studies to provide a framework, areas to focus on when planning agricultural adaptation and the likely costs. It followed key steps for bringing together global and local perspectives for the benefit of both global stakeholders and developing countries.

Zajc, Jožica; Erjavec, Karmen

2014-08-01

While studies on media representations of agricultural biotechnology mostly analyse media texts, this work is intended to fill a research gap with an analysis of journalistic interpretations of media representations. The purpose of this project was to determine how news media represent agricultural biotechnology and how journalists interpret their own representations. A content and critical discourse analysis of news texts published in the Slovenian media over two years and in-depth interviews with their authors were conducted. News texts results suggest that most of the news posts were "othering" biotechnology and biotechnologists: biotechnology as a science and individual scientists are represented as "they," who are socially irresponsible, ignorant, arrogant, and "our" enemies who produce unnatural processes and work for biotechnology companies, whose greed is destroying people, animals, and the environment. Most journalists consider these representations to be objective because they have published the biotechnologists' opinions, despite their own negative attitudes towards biotechnology.

Nuclear agriculture and biotechnology: integrated approaches for crop improvement

International Nuclear Information System (INIS)

Suprasanna, P.; Venugopalan, V.

2017-01-01

Use of radiation and radioisotopes in agriculture is one of the most important fields of peaceful applications of atomic energy for societal benefit. They are used to induce genetic variability in crop plants to develop improved mutant varieties, to manage insect pests, to monitor fate and persistence of pesticides, to study fertilizer use efficiency and plant micronutrient uptake and also to preserve agricultural produce. So far, BARC has developed and released 42 Trombay mutant varieties in oilseeds (groundnut, mustard, soybean, sunflower), pulses (pigeonpea, blackgram, greengram, cowpea), rice and jute for commercial cultivation across the nation. Mutant characterization has been benefitted by genomics approaches and availability of crop genome sequencing. In this regard, studies are underway to utilize mutant germplasm for molecular characterization and understanding trait modification. The nuclear technologies have benefited the farmers, traders and end-users and will continue to play a significant role in addressing food and nutritional security. In this presentation, an overview will be given on the activities of the NABTD in the field of nuclear agriculture and biotechnology

1998-01-01

The petroleum industry's interest in provincial crown land in the agricultural area of Saskatchewan has grown over the last two decades. Agricultural land is regulated by the Saskatchewan Department of Agriculture and Food, Lands Branch. Since 1974 surface lease contracts by oil and gas companies have increased from 1,400 to the present 3,700. Resource lands are regulated by Saskatchewan Environment and Resource Management. There are 8.8 million acres of crown agricultural land in Saskatchewan, most of which is held without title. Crown land management is meant to provide a long term management approach to crown lands that balances economic, environmental and social benefits for present and future generations. The oil and gas industry is an important participant in crown land management. Revenues from petroleum and gas surface leasing, and seismic licensing totals more than five million dollars annually. In 1995/96, there were 54 companies establishing new oil and gas leases on crown land in Saskatchewan. This paper provides details of current policies which apply to petroleum and gas leasing and seismic exploration, and environmental guidelines for companies developing well sites, compressor and metering stations, access roads and easements. 3 tabs

The costly benefits of opposing agricultural biotechnology.

Apel, Andrew

2010-11-30

Rigorous application of a simple definition of what constitutes opposition to agricultural biotechnology readily encompasses a wide array of key players in national and international systems of food production, distribution and governance. Even though the sum of political and financial benefits of opposing agricultural biotechnology appears vastly to outweigh the benefits which accrue to providers of agricultural biotechnology, technology providers actually benefit from this opposition. If these barriers to biotechnology were removed, subsistence farmers still would not represent a lucrative market for improved seed. The sum of all interests involved ensures that subsistence farmers are systematically denied access to agricultural biotechnology. Copyright © 2010 Elsevier B.V. All rights reserved.

Advancing agricultural greenhouse gas quantification*

Science.gov (United States)

Olander, Lydia; Wollenberg, Eva; Tubiello, Francesco; Herold, Martin

2013-03-01

1. Introduction Better information on greenhouse gas (GHG) emissions and mitigation potential in the agricultural sector is necessary to manage these emissions and identify responses that are consistent with the food security and economic development priorities of countries. Critical activity data (what crops or livestock are managed in what way) are poor or lacking for many agricultural systems, especially in developing countries. In addition, the currently available methods for quantifying emissions and mitigation are often too expensive or complex or not sufficiently user friendly for widespread use. The purpose of this focus issue is to capture the state of the art in quantifying greenhouse gases from agricultural systems, with the goal of better understanding our current capabilities and near-term potential for improvement, with particular attention to quantification issues relevant to smallholders in developing countries. This work is timely in light of international discussions and negotiations around how agriculture should be included in efforts to reduce and adapt to climate change impacts, and considering that significant climate financing to developing countries in post-2012 agreements may be linked to their increased ability to identify and report GHG emissions (Murphy et al 2010, CCAFS 2011, FAO 2011). 2. Agriculture and climate change mitigation The main agricultural GHGs—methane and nitrous oxide—account for 10%-12% of anthropogenic emissions globally (Smith et al 2008), or around 50% and 60% of total anthropogenic methane and nitrous oxide emissions, respectively, in 2005. Net carbon dioxide fluxes between agricultural land and the atmosphere linked to food production are relatively small, although significant carbon emissions are associated with degradation of organic soils for plantations in tropical regions (Smith et al 2007, FAO 2012). Population growth and shifts in dietary patterns toward more meat and dairy consumption will lead to

Nuclear techniques in agriculture

International Nuclear Information System (INIS)

Bhagwat, S.G.

2012-01-01

Crops provide us food grains and many other products. Demand for food and other agricultural products is increasing. There is also need for improvement of quality of the agricultural produce. There are several technologies in use for achieving the goal of increasing the quantity and quality of agricultural produce. Nuclear techniques provide us with an option which has certain advantages. The characteristics of crop plants are determined by the genetic make up of the plant. Traditionally the genetic make up was modified using conventional breeding techniques such as cross breeding to improve crops for yield, disease resistance, stress tolerance, resistance to insect pests or to improve quality. New varieties of crops are produced which replace the earlier ones and thus the demands are met. The process of development of new varieties is long and time consuming. Nuclear technique called mutation breeding provides an efficient way of breeding new varieties or improving the older ones. This technique merely enhances the process of occurrence of mutations. In nature mutations occur at a rate of approximately one in a million, while when mutations are induced using radiations such as gamma rays the efficiency of inducing mutations is enhanced. Useful mutations are selected, the mutants are evaluated and developed as a new variety. In the Nuclear Agriculture and Biotechnology Division (NA and BTD) this technique has been used to develop mutants of many crop plants. The mutants can be used to develop a variety directly or by using it in further breeding programme. Using these approaches the NA and BTD has developed 40 new varieties of crops such as groundnut, mungbean, urid, pigeon pea, mustard, soybean, sunflower, cowpea, jute. These varieties are developed in collaboration with other agricultural institutions and are popular among the farming community. The method of mutation breeding can be applied to many other crops for improvement. There is increasing interest among

Reduction potential, shadow prices, and pollution costs of agricultural pollutants in China.

Tang, Kai; Gong, Chengzhu; Wang, Dong

2016-01-15

This paper analyses the reduction potential, shadow prices, and pollution costs of agricultural pollutants in China based on provincial panel data for 2001-2010. Using a parameterized quadratic form for the directional output distance function, we find that if agricultural sectors in all provinces were to produce on the production frontier, China could potentially reduce agricultural emissions of chemical oxygen demand (COD), total nitrogen (TN), and total phosphorus (TP) by 16.0%, 16.2%, and 20.4%, respectively. Additionally, our results show that the shadow price of TN increased rapidly and continuously, while that of COD and TP fluctuated for the whole period. For the whole country, the average shadow price of COD, TN, and TP are 8266 Yuan/tonne, 25,560 Yuan/tonne, and 10,160 Yuan/tonne, respectively. The regional shadow prices of agricultural pollutants are unbalanced. Furthermore, we show that the pollution costs from emissions of COD, TN, and TP are 6.09% of the annual gross output value of the agricultural sector and are highest in the Western and lowest in the Eastern provinces. Our estimates suggest that there is scope for further pollution abatement and simultaneous output expansion for China's agriculture if farmers promote greater efficiency in their production process. Policymakers are required to dynamically adjust the pollution tax rates and ascertain the initial permit price in an emission trading system. Policymakers should also consider the different pollution costs for each province when making the reduction allocations within the agricultural sector. Copyright © 2015 Elsevier B.V.

Comment 5 - agricultural response to climate change

International Nuclear Information System (INIS)

Ruttan, V.W.

1992-01-01

The complex interrelationship between global climate change and agricultural production will become one of the most significant policy issues, in both developed and developing countries, in the first decades of the 21st century. Global and regional climate change will modify both agricultural production capacity and its location. And the intensity of agricultural production will contribute to environmental change at both the regional and global levels

Managing soil organic carbon in agriculture: the net effect on greenhouse gas emissions

International Nuclear Information System (INIS)

Marland, Gregg; West, Tristram O.; Schlamadinger, Bernhard; Canella, Lorenza

2003-01-01

A change in agricultural practice can increase carbon sequestration in agricultural soils. To know the net effect on greenhouse gas emissions to the atmosphere, however, we consider associated changes in CO 2 emissions resulting from the consumption of fossil fuels, emissions of other greenhouse gases and effects on land productivity and crop yield. We also consider how these factors will evolve over time. A change from conventional tillage to no-till agriculture, based on data for average practice in the U.S.; will result in net carbon sequestration in the soil that averages 337 kg C/ha/yr for the initial 20 yr with a decline to near zero in the following 20 yr, and continuing savings in CO 2 emissions because of reduced use of fossil fuels. The long-term results, considering all factors, can generally be expected to show decreased net greenhouse gas emissions. The quantitative details, however, depend on the site-specific impact of the conversion from conventional to no-till agriculture on agricultural yield and N 2 O emissions from nitrogen fertilizer

Population pressure and agricultural productivity in Bangladesh.

Science.gov (United States)

Chaudhury, R H

1983-01-01

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

This guidebook presents a selection of technologies for climate change adaptation in the agriculture sector. A set of 22 adaptation technologies are showcased. These are based primarily on the principles of agroecology, but also include scientific technologies of climate and biological sciences complemented by important sociological and institutional capacity building processes that are required for climate change to function. The technologies cover: 1) Planning for climate change and variability. 2) Sustainable water use and management. 3) Soil management. 4) Sustainable crop management. 5) Sustainable livestock management. 6) Sustainable farming systems. 7) Capacity building and stakeholder organisation. Technologies that tend to homogenise the natural environment and agricultural production have low possibilities of success in environmental stress conditions that are likely to result from climate change. On the other hand, technologies that allow for, and promote diversity are more likely to provide a strategy which strengthens agricultural production in the face of uncertain future climate change scenarios. The 22 technologies showcased in this guidebook have been selected because they facilitate the conservation and restoration of diversity while also providing opportunities for increasing agricultural productivity. Many of these technologies are not new to agricultural production practices, but they are implemented based on the assessment of current and possible future impacts of climate change in a particular location. agroecology is an approach that encompasses concepts of sustainable production and biodiversity promotion and therefore provides a useful framework for identifying and selecting appropriate adaptation technologies for the agriculture sector. The guidebook provides a systematic analysis of the most relevant information available on climate change adaptation technologies in the agriculture sector. It has been compiled based on a literature

Development and outlook for agriculture in international climate negotiations. Climate Report no. 48

International Nuclear Information System (INIS)

Tronquet, Clothilde; Foucherot, Claudine

2015-02-01

Agriculture has a specific role to play in current and future climate change. This carbon-intensive sector, which is responsible for 13.5% of global greenhouse gas emissions, is also highly exposed to the impacts of climate change, including a downward trend and increasing variability in yields. Yet agriculture's capacity to adapt and potential for mitigation also make it part of the solution to climate change. The agricultural sector is often treated as a poor relation in international climate negotiations, which is inappropriate given its specific characteristics and fundamental role. The aim of this report is to consider how agriculture can participate effectively in the United Nations Framework Convention on Climate Change (UNFCCC) negotiations and identify the main challenges faced by this sector in the coming years. An analysis of the history of negotiations and their current situation belies the idea that agriculture plays no part in the UNFCCC process, although it does not enjoy specific consideration as a sector. It falls within the scope of various mitigation and adaptation mechanisms, while its effective participation remains limited. Since 2009, agriculture has also been included in the COP negotiation process and is currently part of the UNFCCC's Subsidiary Body for Scientific and Technological Advice (SBSTA). However, agriculture is only at the first stage of a long and complex negotiation process which cannot be expected to be completed during COP21. While we can hope for COP21 to achieve progress in dialogue regarding monitoring, reporting and verification (MRV) or the adoption of a landscape approach, the SBSTA's work on agriculture will continue beyond 2015, representing a vital step before the development of any operational tools. Multilateral initiatives such as the Global Alliance for Climate-Smart Agriculture are meanwhile helping to mobilise the international community regarding agricultural issues, in parallel with

Health hazards to children in agriculture.

Science.gov (United States)

Wilk, V A

1993-09-01

Children comprise a significant portion of the agricultural workforce and are exposed to many workplace hazards, including farm machinery, pesticides, poor field sanitation, unsafe transportation, and fatigue from doing physically demanding work for long periods. Migrant farmworker children face the additional hazard of substandard or nonexistent housing in the fields. Children account for a disproportionate share of agricultural workplace fatalities and disabling injuries, with more than 300 deaths and 27,000 injuries per year. The most common cause of fatal and nonfatal injury among children in agriculture is farm machinery, with tractors accounting for the greatest number. Remedies to the problems of child labor must take into account family economics and the need for child care. Labor law reform and rigorous enforcement of existing laws and of workplace health and safety requirements are vital to better protect the children and adults working in agriculture.

Sustainable intensification in agricultural systems

Science.gov (United States)

Pretty, Jules; Bharucha, Zareen Pervez

2014-01-01

Background Agricultural systems are amended ecosystems with a variety of properties. Modern agroecosystems have tended towards high through-flow systems, with energy supplied by fossil fuels directed out of the system (either deliberately for harvests or accidentally through side effects). In the coming decades, resource constraints over water, soil, biodiversity and land will affect agricultural systems. Sustainable agroecosystems are those tending to have a positive impact on natural, social and human capital, while unsustainable systems feed back to deplete these assets, leaving fewer for the future. Sustainable intensification (SI) is defined as a process or system where agricultural yields are increased without adverse environmental impact and without the conversion of additional non-agricultural land. The concept does not articulate or privilege any particular vision or method of agricultural production. Rather, it emphasizes ends rather than means, and does not pre-determine technologies, species mix or particular design components. The combination of the terms ‘sustainable’ and ‘intensification’ is an attempt to indicate that desirable outcomes around both more food and improved environmental goods and services could be achieved by a variety of means. Nonetheless, it remains controversial to some. Scope and Conclusions This review analyses recent evidence of the impacts of SI in both developing and industrialized countries, and demonstrates that both yield and natural capital dividends can occur. The review begins with analysis of the emergence of combined agricultural–environmental systems, the environmental and social outcomes of recent agricultural revolutions, and analyses the challenges for food production this century as populations grow and consumption patterns change. Emergent criticisms are highlighted, and the positive impacts of SI on food outputs and renewable capital assets detailed. It concludes with observations on policies and

Full Text Available The article presents the main results of the analysis of the agriculture automation level in Russia and in the world. The results of the research of the foreign market, structures and compositions of foreign-made unmanned mobile energy vehicles are presented. The main direction of development of foreign companies is the creation of new models of navigation and orientation equipment for agricultural machinery aimed to the implementation of autonomous moving and mission equipment control. Technics automatization is possible due to refitting of already existing samples with specialized attachments. According to this analysis, foreign agricultural machinery is far ahead of domestic manufacturers for the production of crew-unmanned facilities of mechanization for the agricultural sector, and the material intensity of the existing agricultural production in Russia is 3-4 times higher than that of foreign countries. The need for this kind of analysis is explained by the result of a comparison labor productivity: this index in Russia's agriculture is by 2.4 times lower than European one and 3.5 times lower than that of the USA. The Russian agriculture development retard can be eliminate through the use of modern achievements in the field of robotic systems for special purposes. The authors proved the possibility of double use of technologies because of similarity of schemes and structure of robotic systems for the solution of specialized tasks of both directions. The unmanned mobile energy vehicles can be used at sequential and parallel autonomous driving.

Full Text Available The aim of this article is to show characteristics of the agricultural policy stricto sensu that favored the agribusiness and agricultural development in Brazil in the past 30 years. To understand this process, the article has a brief description of the instruments of agricultural policy adopted by the Government during this period, so as to adapt to the demands of the WTO and the constraints of the economic situation. In the first phase, from 1964 to 1985, was achieved significantly increase agricultural production by guaranteeing domestic supply, which was a important bottleneck of Brazilian economy in the period pre-1964. Agricultural modernization was achieved with a high social cost, but it should be noted that this issue was not a central concern of the military governments. In the second phase (1985-2001, when Brazil starts the redemocratization, agricultural policy also changes and is consistent with macroeconomic objectives. By that time it was necessary to reduce the fiscal deficit and pay foreign debt. This goal was achieved with the large surpluses generated by the agribusiness despite the drastic reduction of agricultural subsidies. The third period (2002-present seeks to reconcile the promotion of agribusiness with the reduction of poverty, which was an outstanding democratization agenda and which had been postponed according to the need of solving the fiscal and inflation problems from the 80's. Once solved the problem of inflation, the State regain its planning capacity and begins to attack social problems

Quantifying Trade-Offs Among Ecosystem Services, Biodiversity, and Agricultural Returns in an Agriculturally Dominated Landscape Under Future Land‑Management Scenarios

Full Text Available https://doi.org/10.15447/sfews.2017v15iss2art4Change in land use in agriculturally dominated areas is often assumed to provide positive benefits for land-owners and financial agricultural returns at the expense of biodiversity and other ecosystem services. For an agriculturally dominated area in the Central Valley of California we quantify the trade-offs among ecosystem services, biodiversity, and the financial returns from agricultural lands. We do this by evaluating three different landscape management scenarios projected to 2050 compared to the current baseline: habitat restoration, urbanization, and enhanced agriculture. The restoration scenario benefited carbon storage services and increased landscape suitability for birds, and also decreased ecosystem disservices (nitrous oxide emissions, nitrogen leaching, although there was a trade-off in slightly lower financial agricultural returns. Under the urbanization scenario, carbon storage, suitability for birds, and agricultural returns were negatively affected. A scenario which enhanced agriculture, tailored to the needs of a key species of conservation concern (Swainson’s Hawk, Buteo swainsoni, presented the most potential for trade-offs. This scenario benefitted carbon storage and increased landscape suitability for the Swainson's Hawk as well as 15 other focal bird species. However, this scenario increased ecosystem disservices. These spatially explicit results, generated at a scale relevant to land management decision-makers in the Central Valley, provide valuable insight into managing for multiple benefits in the landscape and an approach for assessing future land-management decisions.

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

A Review of Swidden Agriculture in Southeast Asia

Directory of Open Access Journals (Sweden)

Peng Li

2014-02-01

Full Text Available Swidden agriculture is by far the dominant land use system in the mountainous regions of Southeast Asia (SEA. It provides various valuable subsistence products to local farmers, mostly the poor ethnic minority groups. Controversially, it is also closely connected with a number of environmental issues. With the strengthening regional economic cooperation in SEA, swidden agriculture has experienced drastic transformations into other diverse market-oriented land use types since the 1990s. However, there is very limited information on the basic geographical and demographic data of swidden agriculture and the socio-economic and biophysical effects of the transformations. International programs, such as the Reducing Emissions from Deforestation and forest Degradation (REDD, underscore the importance of monitoring and evaluating swidden agriculture and its transition to reduce carbon emission due to deforestation and forest degradation. In this context, along with the accessibility of Landsat historical imagery, remote sensing based techniques will offer an effective way to detect and monitor the locations and extent of swidden agriculture. Many approaches for investigating fire occurrence and burned area can be introduced for swidden agriculture mapping due to the common feature of fire relatedness. In this review paper, four broad approaches involving spectral signatures, phenological characteristics, statistical theory and landscape ecology were summarized for swidden agriculture delineation. Five research priorities about swidden agriculture involving remote sensing techniques, spatial pattern, change, drivers and impacts were proposed accordingly. To our knowledge, a synthesis review on the remote sensing and outlook on swidden agriculture has not been reported yet. This review paper aims to give a comprehensive overview of swidden agriculture studies in the domains of debated definition, trends, remote sensing methods and outlook research in SEA

There are many opportunities to leverage agricultural resources on existing lands without interfering with production of food, feed, fiber, or forest products. In the recently developed advanced biomass feedstock commercialization vision, estimates of potentially available biomass supply from agriculture are built upon the U.S. Department of Agriculture’s (USDA’s) Long-Term Forecast, ensuring that existing product demands are met before biomass crops are planted. Dedicated biomass energy crops and agricultural crop residues are abundant, diverse, and widely distributed across the United States. These potential biomass supplies can play an important role in a national biofuels commercialization strategy.

Katayama, Naomi; Njemanze, Philip; Nweke, Felix; Space Agriculture Task Force, J.; Katayama, Naomi; Yamashita, Masamichi

Looking on African perspective in space agriculture may contribute to increase diversity, and enforce robustness for advanced life support capability. Cassava, Manihot esculentaand, is one of major crop in Africa, and could be a candidate of space food materials. Since resource is limited for space agriculture in many aspects, crop yield should be high in efficiency, and robust as well. The efficiency is measured by farming space and time. Harvest yield of cassava is about 41 MJ/ m2 (70 ton/ha) after 11 months of farming. Among rice, wheat, potato, and sweet potato, cassava is ranked to the first place (40 m2 ) in terms of farming area required to supply energy of 5 MJ/day, which is recommended for one person. Production of cassava could be made under poor condition, such as acidic soil, shortage of fertilizer, draught. Laterite, similar to Martian regolith. Propagation made by stem cutting is an advantage of cassava in space agriculture avoiding entomophilous or anemophilous process to pollinate. Feature of crop storage capability is additional factor that determines the efficiency in the whole process of agriculture. Cassava root tuber can be left in soil until its consumption. Cassava might be an African contribution to space agriculture.

In this study, the current energy status of Turkey and the effects of national energy policies on Turkish agricultural support policies are discussed for both current and future requirements. Turkey is an energy-importing country producing 30 mtoe (million tons of oil equivalent) energy but consuming 80 mtoe. The energy import ratio of Turkey is 65-70% and the majority of this import is based on petroleum and natural gas. Furthermore, while world energy demand increases by 1.8% annually, Turkey's energy demand increases by about 8%. Although energy consumption in agriculture is much lower than the other sectors in Turkey, energy use as both input and output of agricultural sector is a very important issue due to its large agricultural potential and rural area. Total agricultural land area is 27.8 million hectares and about 66.5% of this area is devoted for cereal production. On the other hand, Turkey has over 4 million agricultural farm holdings of which 70-75% is engaged in cereal production. Machinery expenses, mainly diesel, constitute 30-50% of total variable expenses in cereal production costs. It is observed that energy policies pursued in agriculture have been directly affected by diesel prices in Turkey. Therefore, support policy tools for using diesel and electricity in agriculture are being pursued by the Turkish government

Full Text Available Agriculture represents the branch of the material production which deals with growing crops and raising animals in order to obtain farm produce and some raw materials, as well asthe totality of works and methods used for this purpose. Agriculture has specific traits mainly induced by the traits of its results. Thereupon, what sets apart agriculture from other sectors of the economy is the volume, structure and concretization of the resources in the process of their consumption. The essential cause of these differences is the fact that land is the main production factor and that, compared to the development level of the production forces and the natural and biological factors, it behaves in a specific manner.Definitions and characteristics of agricultural activities are given also in The International Financial Reporting Standards (IFRS , respectively IAS 41, “Agriculture”. Hence, according to IAS 41 “Agriculture”, agricultural activity is defined as the management of the biological transformation of biological assets (living plants and animals into agricultural produce (harvested product of the entity's biological assets. The received concessions represent an important characteristic of these units and, as a particular case concerning such concessions, we will tackle the issue of terrains pertaining to the assets sold by the Romsilva National Forests Administration.
