The controversy between Margaret Mead and Derek Freeman about Mead's work (1928) on coming of age in Samoa in the 1920s is analyzed. Freeman's claim to have refuted Mead's findings can be easily refuted itself. Mead's study, arguing that adolescent turmoil is not universal, stands the test of time. (SLD)

Adjustment of the water treatment process to changes in water quality is a focus area for engineers and managers of water treatment plants. The desired and preferred capability depends on timely and quantitative knowledge of water quality monitoring in terms of total suspended solids (TSS) concentrations. This paper presents the development of a suite of nowcasting and forecasting methods by using high-resolution remote-sensing-based monitoring techniques on a daily basis. First, the integrated data fusion and mining (IDFM) technique was applied to develop a near real-time monitoring system for daily nowcasting of the TSS concentrations. Then a nonlinear autoregressive neural network with external input (NARXNET) model was selected and applied for forecasting analysis of the changes in TSS concentrations over time on a rolling basis onward using the IDFM technique. The implementation of such an integrated forecasting and nowcasting approach was assessed by a case study at Lake Mead hosting the water intake for Las Vegas, Nevada, in the water-stressed western U.S. Long-term monthly averaged results showed no simultaneous impact from forest fire events on accelerating the rise of TSS concentration. However, the results showed a probable impact of a decade of drought on increasing TSS concentration in the Colorado River Arm and Overton Arm. Results of the forecasting model highlight the reservoir water level as a significant parameter in predicting TSS in Lake Mead. In addition, the R-squared value of 0.98 and the root mean square error of 0.5 between the observed and predicted TSS values demonstrates the reliability and application potential of this remote sensing-based early warning system in terms of TSS projections at a drinking water intake.
Competing risks and the development of adaptive management plans for water resources: Field reconnaissance investigation of risks to fishes and other aquatic biota exposed to endocrine disrupting chemicals (edcs) in lake mead, Nevada USA
Linder, G.; Little, E.E.
The analysis and characterization of competing risks for water resources rely on a wide spectrum of tools to evaluate hazards and risks associated with their management. For example, waters of the lower Colorado River stored in reservoirs such as Lake Mead present a wide range of competing risks related to water quantity and water quality. These risks are often interdependent and complicated by competing uses of source waters for sustaining biological resources and for supporting a range of agricultural, municipal, recreational, and industrial uses. USGS is currently conducting a series of interdisciplinary case-studies on water quality of Lake Mead and its source waters. In this case-study we examine selected constituents potentially entering the Lake Mead system, particularly endocrine disrupting chemicals (EDCs). Worldwide, a number of environmental EDCs have been identified that affect reproduction, development, and adaptive behaviors in a wide range of organisms. Many EDCs are minimally affected by current treatment technologies and occur in treated sewage effluents. Several EDCs have been detected in Lake Mead, and several substances have been identified that are of concern because of potential impacts to the aquatic biota, including the sport fishery of Lake Mead and endangered razorback suckers (Xyrauchen texanus) that occur in the Colorado River system. For example, altered biomarkers relevant to reproduction and thyroid function in fishes have been observed and may be predictive of impaired metabolism and development. Few studies, however, have addressed whether such EDC-induced responses observed in the field have an ecologically significant effect on the reproductive success of fishes. To identify potential linkages between EDCs and species of management concern, the risk analysis and characterization in this reconnaissance study focused on effects (and attendant uncertainties) that might be expressed by exposed populations. In addition, risk reduction

Full Text Available Mead is a traditional alcoholic drink derived from the fermentation of diluted honey in the presence of appropriate yeast. Its modern production, in general terms, involves the addition of nutrients to initial diluted honey, pasteurization, yeast inoculation, fermentation and removal of impurities. Undesirable events along the process have been reported; among them, we highlight: delayed or arrested fermentations, modified and unpleasant sensory and quality parameters of the final product. These problems have been linked to the inability of yeasts to accomplish their role in extreme growth conditions. Emphasis has also been placed on the long fermentation times required, ranging from weeks to months, particularly when traditional procedures are applied and when the honey concentration is low. A series of alterations to the must and technological changes have been proposed in order to optimize the mead production process. In this context, this review examines the evidence that aims to improve meads’ quality and make the production process easier and more efficient, by clarifying the source of unexpected events, describing the implementation of different fermentative microorganisms and using new methodologies.
Beginning in 1933, while working in New Guinea, Margaret Mead developed her so-called squares hypothesis. Mead never published its terms, though she made a brief comment on it in her autobiography, Blackberry Winter (1972), and the arguments found in Sex and Temperament in Three Primitive Societies (1935) and the research leading to Balinese Character (Bateson & Mead, 1942) bore its imprint. Beginning with William McDougall's distinction between temperament (innate predispositions) and character (learned organization of habit), Mead articulated a morphological approach to the interplay between biology and culture that yielded four primary and four intermediary personality types. Under specified but not inevitable circumstances, the conscious choices of a given people could render one or another of these types characteristic or predominantly stable within their population, giving each of the other types a definite relation to the dominant type and thereby the cultural ethos of its society. Persons of each type followed a developmental path specific to their type different both from that of other types and in its manifestations given the various relations of the individual's type to the dominant type. Mead's hypothesis was, therefore, a vision of the unity and diversity of a single human species as well as an approach to the differing psychological positioning of individuals in cultures. In examining Mead's hypothesis, this essay also takes up Mead's debts to several leading psychologists (McDougall, C. G. Jung, and Erik Erikson), and (provisionally) how her vision differed from that of Ruth Benedict.
Full Text Available Agriculture today is a strategic point of a country's economy, providing food based on population, development of internal and external trade and manufacturing industries by supplying raw materials. For Romania, this branch is a strong point both in terms climatic (temperate, balanced relief, soil quality and at the same time is also a way of national development and convergence of rural areas to their full potential untapped. With strong reforms, well implemented, a specific legislative framework which aims to protecting private property, Romania could reduce the low efficiency and can have a sustainable agriculture. The paper aimed to present the advantages of consuming organic products, and, on the other hand, the advantages of a country in terms of organic farming. European agriculture is a competitive, market-oriented, but also protecting the environment model.
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.

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

This paper seeks to clarify those conceptual foundations of G.H. Mead's social behaviorism which are assumed, but not made explicit, in that writer's well-known volume Mind, Self and Society. These foundations are shown to be an outgrowth of Mead's early commitment to the organic conception of conduct underlying the psychological functionalism of the Chicago School. Further light is shed upon Mead's position by pointing out the fundamental differences between his model of conduct and that characteristic of the behaviorist tradition in American psychology.
With advance of urbanization and industrialization, modern agricultural development in Chinas economic developed areas (CEDAs) is greatly restricted by traditional concept. To speed up the development of modern agriculture in CEDAs, this paper takes Suzhou City as an example from theories supporting modern agricultural development. It demonstrates agriculture in CEDAs plays an important role in adjusting supply of agricultural and sideline products, reserving rural labor employment, protecting ecological environment, increasing farmers income, and passing on agricultural culture. It contends that CEDAs should take reserving basic farmland as prerequisite; take adequate supply of primary agricultural products, protection of living environment, maintenance of agricultural landscape, and inheritance of farming culture as objectives; establish perfect modern agricultural system through firmly setting up modern agricultural value concept; increase local public finance input; increase agricultural functional value from technical and management levels, to realize increase of farmers income, promote sustainable development of agriculture, promote integrated urban and rural development, as well as harmonious development of human and nature.

Within 30 years the world will be supplying food for an additional 2.5 billion people, most of whom will live in developing countries. Developing countries in meeting future challenges will need to implement sound and stable macroeconomic and sector policies. The World Bank is providing analysis, policy dialogue, and financial support in specific countries for opening up agricultural markets globally. Developing countries need to enhance food supplies by encouraging rapid technological change, increasing the efficiency of irrigation, and improving natural resource management. Agricultural and income growth in developing countries is dependent upon transfer of the breakthroughs in agricultural technology to the millions of small farms in the developing world. People currently use about 70% of available fresh water for irrigation, and competition for water resources with urban and industrial users has increased. Agriculture and other sectors must increase the efficiency of water use. Natural resource planning and comprehensive water and natural resource management that rely on a community-based approach have proven successful. Developing countries need to improve access to food by strengthening markets and agribusinesses, providing education and health services to both boys and girls, investing in infrastructure, and fostering broad participation. The major challenge ahead is to ensure food security for the hundreds of millions of families living in poverty. This large and complex task involves increasing agricultural output worldwide, reducing poverty, and improving health and nutrition. Progress has been made in the past 25 years in improving living conditions, but not everyone has benefitted. Almost 75% of the poor live in rural areas without access to land, and 25% are urban poor without jobs. Most of the poor live in Asia and sub-Saharan Africa. The World Bank mandate is to reduce poverty and hunger through revitalized rural development.

Full Text Available The article says that small agricultural farms (SAF play a significant role in import substitution of food, which is aimed at replacing imported agricultural commodities and finished products to domestic security. SAF subjects of Krasnodar region made a significant contribution to the increase of efficiency of regional economy. The share of small agricultural farms is 29% of regional production of grain and meat, 36% of milk, 47% of egg, 10% of sugar beet, 30% of sunflower and 95% of potatoes, 70% of vegetables, and 29% of grapes which makes a significant contribution to the process of import substitution. In addition, the SAF showed a large positive impact on the sustainability of farming, the development dynamics of the entire rural economy, increase the competitiveness of the whole field due to the increase in segment sales, improving market sales in the infrastructure. Today SAF perform a priority vector of development of regional agrarian policy. However, when the share of regional agricultural production segment is more than 35%, a small management gets only 10% of the sum of all sources of state support. In recent years, stimulation measures of subjects of small agrarian farms aimed at increasing the size of the land, the abolition of the standards concerning the number of animals, improving lending conditions, facilitating the starting of economic conditions, union efforts to organize sales channels and other programs. However, the situation with crediting SAF is improving too slowly due to lack of sufficient collateral, and only a small part of them can use loans. Besides, the bureaucratic and departmental barriers are still saved. They still face trade discrimination in the retail markets and great difficulties due to the new requirements of the construction markets, the endowment channels marketing of products etc. All this dictates the need for further improvement of the economic mechanism of regulation of small agricultural

However, even though the prices are higher on the organic market, farmers do not always manage to benefit from these better prices. Romania is a country with a high potential for organic agriculture as there are 14.8 million hectares of agricultural land out of which arable land represents 8.9 million ha. According to NIS (2012a p. 89, in 2011, 29.2% of the country’s population was employed in agriculture. However, most households in rural areas produce for mere survival due mainly to the highly fragmented land owning. Therefore there is an acute need for new development strategies in order to improve living standards in rural areas. This article describes business models of organic cooperatives in Nepal and Romania. Moreover it proposes a rural development initiative based on the creation of organic cooperatives and suggests thata NGOs could implement such a program.

Feeding a growing population exceeding 1 billion is a big challenge to the Chinese government and has partly led to the self-sufficient policy in grain production and supply for decades. However, the efforts to push grain production everywhere have resulted in not only deterioration of the environment but also stagnation or even reduction in farmers'income as production costs continue to increase.This situation might be worsening after China's accession to the WTO that provides market access for bulk commodity imports. A sustainable development in Chinese agriculture depends on diversification, or structural adjustment, that allows Chinese farmers to fully utilize their comparative advantage in production of labor-intensive goods.Past experience has shown that diversification has contributed more than a half of the growth in Chinese agriculture during the reform period and reduced stresses on the environment at the same time. It is likely to contribute even more to Chinese agriculture in the future and in a sustainable manner.

Full Text Available Habermas pensa a questão da individuação e da socialização a partir dos estudos de George Hebert Mead, que, na sua concepção, foi o primeiro a refletir substancialmente sobre um modelo de eu produzido socialmente. Mead oferece todo subsídio teórico para o desenvolvimento de uma teoria da evolução humana que envolve o processo de individuação e de socialização. Pelo paradigma de intercompreensão, ou seja, da relação intersubjetiva de indivíduos que se socializam por meio da comunicação e se reconhecem mutuamente, Mead permite a mudança de paradigma da consciência de si, da autorreferência de um sujeito que age isoladamente para o indivíduo que processa trocas sociais mediante a linguagem. Portanto, um dos principais componentes da teoria de Mead, em que Habermas busca contribuição para sua Teoria da Ação Comunicativa, é o processo de constituição do "eu", sua identidade. Mead acredita ser a individuação representada como um processo que é linguisticamente mediador da socialização e da construção de uma história de vida, na qual os sujeitos são conscientes de si. É esse meio linguístico estabelecido entre os sujeitos e o meio do entendimento intrassubjetivo e histórico vital que possibilita a formação de uma identidade de sujeitos socializados. É o reconhecimento intersubjetivo e autoentendimento mediado intersubjetivamente que propicia a formação da identidade. Esse quadro conceitual será fundamental a Habermas, na sua acepção de eu pós-convencional.Habermas discusses the question of individualization and socialization on the basis of the studies of George Herbert Mead, who, in Habermas' view, was the first to reflect substantially on a model of the socially produced "I". Mead offers a theoretical basis for the development of a theory of human evolution that involves the process of individualization and socialization. Through the paradigm of mutual understanding, that is, the intersubjective

Full Text Available The paper focuses on the situation of the agricultural land market in Slovakia and in selected region of the SR – Nitra region, on the application and development of agricultural land prices in Slovakia and on the factors that influence the decisions of agricultural enterprises on the market with agricultural land. In this paper were used primary data obtained with interview method realized within the research of Department of European policies, Slovak University of Agriculture during the period 2012 – 2013 in all districts of region Nitra. The evaluation of the impact of agricultural subject on agricultural land market in Slovakia was realized by using the method of regression analysis. Based on the results from the research we can state that entrepreneurs still prefer more to rent land then to purchase a land. The main factors influencing the decision-making process of agricultural subjects are ownership fragmentation, the fragmentation of agricultural plots and business's financial situation and profitability of the purchase. Many entrepreneurs pointed to this indicator as one of the most influential in terms of increasing the market price, respectively as a reason for not signing the lease agreement. The agricultural land market in Slovakia is emerging but still not sufficiently transparent. Further development of the market will continue to be marked by the overall economic situation in agriculture, relatively low competitiveness of Slovak farmers in the European market and reduced profitability. Research showed that the most pronounced effect on the price of agricultural land and the amount of rent for agricultural land has the number of enterprises. Growing number of farms will increase the price or amount of rent for agricultural land.

Creative agriculture is a new agricultural type with originality as a key element, integrating agricultural production activities into creative activities such as culture and art, broadening functions of agriculture and improving added value of agricultural products. Creative agriculture is characterized by external economy, technology integration, art appreciation, high efficiency and value, and it is significant for promoting inheritance of traditional culture, optimal allocation and regeneration of resources, optimal distribution of elements, expansion of agricultural functions, construction of beautiful countryside, cultural construction of rural areas, transformation of agricultural and rural economic growth mode. With agricultural resources as the foundation, sightseeing and leisure agriculture as the breakthrough point, by means of science and technology, many regions in China have explored products of creative agriculture and presented several typical cases of creative agriculture. However, these projects are mostly restricted by problems such as poor development concept, lack of supportive policies, and ineffective industrial integration. Taking Zhejiang Province as an example, we proposed path choice, supportive system and relevant policy suggestions for the development of creative agriculture.

Full Text Available Agriculture and its development is the foundation of development in Iran as a developing country. So, it can be regarded as the foundation for economical and social development. The capabilities of agriculture sector are limited and its efficiency is trivial because of neglecting agricultural development and keeping its support just as a slogan. The transformation of agriculture to a developed, dynamic, efficient environment depends not only on appropriate climate and natural resources but also on human resource development in the relevant sector. The main purpose of the present research was to study and recognize agricultural development indicators from agriculture experts’ viewpoints (including researchers, trainers and extension experts in six provinces in Iran on the basis of Adjacent Provinces Plan. The study was designed with three phases of theoretical foundations, field operations and data analysis. The statistical population was 863 experts, out of which 198 experts were selected by stratified sampling.

African agriculture is already struggling to meet increasing demand for food. Climate change, which will alter agroecological conditions and looks set to arrest and decrease agricultural yields on the continent, will make it even harder to achieve food security. Boosting agricultural productivity in Africa, especially in the face of climate change, cannot be achieved without the benefits of cutting edge science. Advances in technology development and transfer, capacity building and policy research must be harnessed by developing and disseminating relevant strategies and technologies, and improving policy environments. The European Initiative for Agricultural Research for Development (EIARD), which facilitates and coordinates European policy and support for agricultural research for development, must integrate climate change into its activities and ensure that agricultural research for development and climate change adaptation are not disjointed. This demands a more strategic and coordinated approach from the initiative — one that reflects African realities, responds to African priorities for adaptation and development, and makes the best use of limited resources.

Full Text Available The article reviews primary directions for economical regulation of agriculture, for solving problems of insufficient funds of agricultural enterprises. Goals for development of agricultural economics growth and competitive abilities are determined, economical measures for governmental support are described as functions of system for development of agricultural market. The authors reveal the problems of innovational and optimizational model for development of agriculture, and system of state regulative and supportive measures for implementing the innovational model of development by consolidation of self-development mechanisms within revealing of inner economical reserves and activisation of “growth points” for resource potential. The mutual system dependence for mechanisms of taxes and subsidiaries and their influence on budget and socio-economical externalities are analyzed. It is substantiated that the state regulation of agricultural markets must take into account low incomes of small agricultural business, not allowing to accumulate necessary funds for starting cooperation. Due to that, the article specially reviews issues of loan availableness for small agricultural enterprises, including private farmings, peasant farms and cooperatives created by them, and, for this goal, the issues of marketing effectiveness for production of such small forms of agriculture are further reviewed. As a result of research, the authors discovered the necessity for government support of socially important businesses in agriculture, which are not of high profitability and, due to that, are not attractive for investors, but are necessary for saving the traditional rural lifestyle and maintaining important social functions for sustainable development.
The agricultural economy in Anhui Province is developing so fast,but farmers are severely affected by the frequent occurrence of natural disasters. The current agricultural insurance mode is not suitable,therefore,the research on agricultural insurance modes of Anhui Province helps to promote the steady development of the agricultural production. Starting from situation of agricultural insurance in Anhui Province,learning from both experience of foreign country and the latest successful domestic modes,we try to put forward agricultural insurance mode framework which is suitable for Anhui Province. Based on the actual situation of Anhui Province,it is necessary to adopt the mode of government leading combined with agricultural mutual aid rather than copy the existing mode.

Agricultural holdings in the Podlaskie voivodeship registered in the FADN system in 2011–2012 were investigated. Assessment accounted for agroecological indicators (share of permanent grasslands, share of cereals in crops, soil coverage with vegetation, stock density and economic indicators (profi tableness of land and labor. Analysis was conducted according to a classifi cation into agricultural holding types: fi eldcrops, dairy cattle, and granivores. Fieldcrop and granivore holdings achieved more favourable environmental sustainability indicators. Holdings specializing in dairy cattle breeding posed a threat to the natural environment, mainly due to their excessive stock density. Economic sustainability assessment showed that granivore holdings were assessed most favorably. In these holdings, holding income per full-time worker was 37% greater than in fi eldcrop holdings and 57% greater than in dairy cattle holdings.

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

My aim is to discuss the history of the reception of George Herbert Mead's ideas in sociology. After discussing the methodological debate between presentism and historicism, I address the interpretations of those responsible for Mead's inclusion in the sociological canon: Herbert Blumer, Jürgen Habermas, and Hans Joas. In the concluding section, I assess these reconstructions of Mead's thought and suggest an alternative more consistent with my initial methodological remarks. In particular, I advocate a reconstruction of Mead's ideas that apprehends simultaneously its evolution over time and its thematic breadth. Such a historically minded reconstruction can be not only a useful corrective to possible anachronisms incurred by contemporary social theorists, but also a fruitful resource for their theory-building endeavors. Only then can meaningful and enriching dialogue with Mead begin.
Full Text Available Agriculture in Africa is not sustainable because average yields have been stagnating for decades due to underinvestment, especially in the development of agricultural markets, crop improvement and the sustainable management of agricultural systems. Low public sector funding for agricultural research and lack of incentives for the private sector to operate in areas where there is no market largely explain the yield gap in many food-importing developing countries. Yet, there are effective ways in which the public and the private sector could work together and jointly improve agricultural sustainability in poor countries. The public sector provides a favorable institutional environment for the development of agricultural markets and investment in rural infrastructure, facilitates local business development and funds research with local relevance. The private sector, in return, brings its considerable expertise in product development and deployment. This article illustrates how new forms of public-private partnerships (PPPs for agricultural development can work in challenging environments. It discusses three promising examples of PPPs in which the Syngenta Foundation for Sustainable Agriculture (SFSA is actively involved, and shows that an experimental approach can sometimes be more effective than social planning in efforts to achieve sustainable agriculture.

Based on the brief account of the connotation of transforming economic development pattern and government functions,the thesis will introduce the development status of agricultural economy in Guizhou Province:firstly,single agricultural industrial structure;secondly,large gap between urban and rural development;thirdly,low-level utilization of agricultural science and technology;fourthly,fierce contradiction between agricultural mode of production and ecological environment.Then it analyzes the basic requirements for government functions in transforming the development pattern of agricultural economy in Guizhou Province:the first one is the function to guide sustainable development and the structural adjustment of agricultural production;the second is the function to coordinate urban-rural development and equally supply basic public goods;the third is the function to input science and technology to serve agriculture;the fourth one is the dominant function to promote the harmonious development of man and nature as well as to reduce the number of peasants.In order to promote the transformation of agricultural development mode and maintain the sound and rapid economic development,some corresponding measures and suggestions are proposed from the perspective of government functions:firstly,promoting the optimization and upgrading of industrial structure;secondly,the government should take the lead in providing rural public goods;thirdly,strengthening the skills training and technological education of rural labor force;fourthly,reducing the number of farmers and retaining the farmers.
Through the study of relationship between agricultural technology extension and the development of agricultural modernization,urbanization and industrialization,it is found that agricultural technology extension is an important means to achieve synchronous development of agricultural modernization,urbanization and industrialization. Based on the sample data in China during 1978-2011,we perform the empirical analysis using VAR model and cointegration analysis and impulse response methods. The results show that there is a long-term positive equilibrium relationship between agricultural technology extension and the development of agricultural modernization,urbanization and industrialization,and agricultural technology extension plays a role in promoting agricultural modernization,urbanization and industrialization to varying degrees. Finally,it is concluded that there is a need to establish efficient agricultural technology extension mechanism and diversified agricultural technology extension investment mechanism to make agricultural technology extension better promote China’s agricultural modernization,urbanization and industrialization.

Full Text Available Bioelectrochemical systems (BES are a newly emerged technology for energy-efficient water and wastewater treatment. Much effort as well as significant progress has been made in advancing this technology towards practical applications treating various types of waste. However, BES application for agriculture has not been well explored. Herein, studies of BES related to agriculture are reviewed and the potential applications of BES for promoting sustainable agriculture are discussed. BES may be applied to treat the waste/wastewater from agricultural production, minimizing contaminants, producing bioenergy, and recovering useful nutrients. BES can also be used to supply irrigation water via desalinating brackish water or producing reclaimed water from wastewater. The energy generated in BES can be used as a power source for wireless sensors monitoring the key parameters for agricultural activities. The importance of BES to sustainable agriculture should be recognized, and future development of this technology should identify proper application niches with technological advancement.
On the basis of industrial division of China’s Securities Regulatory Commission,listed companies in the processing industry of agro-products and food production industry have also been incorporated into agricultural listed companies.Developmental discrepancy of agricultural listed companies is analyzed.The main manifestations are small population quantity,slow development,weak growing capacity,relatively poor rationality and unbalanced regional distribution.The internal causes of this kind of situation lie in the weak quality and inadequate developmental driving force of agricultural listed companies,while the external causes are the capital chasing and unbalanced political support of the country.Therefore,the key of quickening the development of agricultural listed companies is inner power and external competition.Thus,the political thoughts of the development of agricultural listed companies are proposed.

This paper introduces the concepts and aims of sustainable agriculture in China. Sustainable agricultural development comprises sustainability of agricultural production, sustainability of the rural economy, ecological and environmental sustainability within agricultural systems and sustainability of rural society. China's prime aim is to ensure current and future food security. Based on projections of China's population, its economy, societal factors and agricultural resources and inputs between 2000 and 2050, total grain supply and demand has been predicted and the state of food security analysed. Total and per capita demand for grain will increase continuously. Total demand will reach 648 Mt in 2020 and 700 Mt in 2050, while total grain yield of cultivated land will reach 470 Mt in 2010, 585 Mt in 2030 and 656 Mt in 2050. The per capita grain production will be around 360kg in the period 2000-2030 and reach 470kg in 2050. When productivities of cultivated land and other agricultural resources are all taken into consideration, China's food self-sufficiency ratio will increase from 94.4% in 2000 to 101.3% in 2030, suggesting that China will meet its future demand for food and need for food security. Despite this positive assessment, the country's sustainable agricultural development has encountered many obstacles. These include: agricultural water-use shortage; cultivated land loss; inappropriate usage of fertilizers and pesticides, and environmental degradation.

This paper emphasizes the benefits of an agricultural strategy of development in developing countries. It begins by analyzing the close links between food and employment in the development process. In an underdeveloped country, food production is minimal, but demand is as well because of the small population growth. After development begins, income rises and food demand outstrips production. Only at later stages of development can food production meet demand. The middle stage of development describes most developing countries, which have averaged annual growth rates of 3% per capita in 1966-80. The growth in food demand must be met through technological advance in agriculture: high-yield seeds, fertilizers, and irrigation, which, for example, helped India increase cereal yields 29% between 1954-55 and 1964-65. The rate of growth in cropped areas has declined between 1961-1980, making increased yields more necessary. Growth in employment and income leads to higher food demand, which leads to higher prices and labor costs and a tendency towards capital-intensive agriculture. As the rural sector becomes wealthier, there is also more opportunity for non-agricultural rural workers, creating still more demand. In the final development stage, agricultural products can generate foreign exchange. In Asia, the priority is to ensure efficient outcomes of capital allocations, while in Africa, technology must be instituted. Public investment has been shown to be essential to rapid development in Japan, Taiwan, and the Punjab of India. The absence of this investment in Africa, partly because of an overemphasis on urban sector investment, is largely responsible for the backward state of African agriculture. Often rural areas are overtaxed, agricultural experts are lacking, and there is a growing presence of urban bureaucrats. Both experts in the donor community and farmers themselves must become more vocal in demanding investment in the agricultural sector.

Lake Mead, particularly its Boulder Basin, is one of the most intensively monitored reservoirs in the United States. With its importance to societal needs and ecosystem benefits, interest in water quality and water resources of Lake Mead will remain high. A number of agencies have authorities and management interests in Lake Mead and maintain individual agency monitoring programs. These programs were enhanced on an interagency basis from 2004 to 2012 to facilitate intensive monitoring in all major basins of the lake. Recognition that increasing stressors and influences in individual basins can affect water quality throughout Lake Mead and gave rise to an even stronger effort towards the development of holistic and effective interagency approaches. In 2010, agency monitoring programs were used to develop a management plan for water-dependent resources at Lake Mead National Recreation Area (LMNRA). The Long-Term Limnological and Aquatic Resource Monitoring and Research Plan for Lakes Mead and Mohave (the Plan; National Park Service, 2010) documented key management questions to be addressed through monitoring and research, and identified interagency strategic objectives for water quality and water-dependent resources. Moreover, the Plan provides a framework for summarizing water quality and water resource information in five resource categories: water quality and limnology; fish and aquatic biota; sediments; birds; and riparian vegetation. The Plan also addresses three stressors to lake resources: contaminants, invasive species, and climate change. For each of these topics, the current (2012) state of knowledge is summarized for LMNRA (table 7-1), including key scientific questions and findings, management implications, and information needs. A more detailed discussion for each topic follows.

This paper introduces two new respiratory system models, the Mead-Cw model and the Mead-Cl model, which are 6-component models that are intermediate in complexity between the well-known 7-component Mead model and the recently proposed 5-component augmented RIC model (derived from the Mead model by eliminating both Cw and Cl). Their modeling errors were compared to the RIC, extended RIC, augmented RIC and Mead models, for component values estimated from IOS data. The two new models yielded lower errors than all the other models, except for the Mead model. However, the Mead-Cl model and the Mead-Cw model also yielded unreasonably large values for Cw and Cl, respectively, which are known disadvantages of the Mead model. Hence the augmented RIC model appears to be the most useful at present for IOS-based computer-aided detection and diagnosis of respiratory disorders.

Full Text Available Economic development within rural areas of the Republic of Moldova is affected by multiple issues which cross the agricultural individual sector development. One of the main factors that would influence positively the development of agriculture is investment. Investment plays an important role on the country's economy, representing the material support of its economic and social development. It ensures the permanent capital increase, advances the technical and economic efficiency of existing ones and creates new places of employment. In this context, investment is the decisive element of economic growth, of the intensive, qualitative and effective factors promotion.

Full Text Available The article provides data with respect to the modern state and tendencies of development of the agrarian sector of Ukraine. The issue of the optimal size of an agricultural enterprise is discussed in the scientific literature. The world practice shows that competitive advantages of farms are achieved through their unification for creation of various partnerships and co-operatives, which operate on the unprofitable basis. Powerful industrial enterprises, financial, trading and service structures took advantage of absence of co-operatives and monopolised production of agricultural products, holding significant areas of agricultural land on lease. Today, ten biggest Ukrainian agro-holdings have more than three million hectares of land or 7.5% of all lands. Big capital, trying to maximise profit, is specialised, as a rule, in mono-production. The article shows main ways of strategic development of agriculture in Ukraine. Depending on the main form of farm management, there are two directions of further development of agro-industrial production: development of big agro-industrial formations (branch organisation of agro-industrial production and vertical integration in the agro-industrial complex (AIC or co-operatives (territorial organisation of agro-industrial production and horizontal integration in AIC. Depending on the way selected by the state, an organisational and economic mechanism is created. The article develops conceptual grounds of state regulation of AIC in the context of development of major agro-industrial formations and agricultural service co-operatives.
In recent years,China’s economic construction enters into a new development period.The buyer’s market appears,structural demand of agricultural products becomes excessive,and the demand market becomes depressed.In the process of seeking approaches for expanding domestic demands,accelerating construction of small towns is a breakthrough point of rural population urbanization,and also an optimal approach for realizing transfer of rural surplus labor.Besides,accelerating construction of small towns is an inevitable path for intensive management of rural land implementing ecological agriculture,and also an optimal path for improving farmers’ quality and improving living conditions.In addition,it is an essential strategy for increasing consumption,expanding domestic demand,pulling rural economic and social development,and also a powerful measure for realizing sustainable development of agriculture.In the process of construction of rural urbanization,it is required to attach importance to strategy of sustainable development of agriculture.This is beneficial for the present generation and for descendants.Therefore,how to build small towns and how to solve many problems in sustainable development of agriculture have received much concern.
In China,the vertical coordination development mode of agricultural products can be divided into traditional market-oriented transaction mode with fluctuation according to market conditions,made-to-order on the basis of farmer organization,company leading cooperative mode,share or shareholding cooperative mode,and vertical integration mode. There are differences in coordination characteristics,advantages and disadvantages,and adaptability between different modes. Traditional vertical coordination mode is transforming and upgrading to close and high-efficient mode. In this process,it is influenced by factors such as cost-benefit balance between farmers and agricultural product processing enterprises,special use of agricultural product processing,structure of agricultural product industry chain,and action of local government.

Drylands of the world cover 41% of the Earth's land surface and are a direct source of livelihood for 6.5 billion people, especially in developing countries. However, nearly all drylands are at risk of land degradation as a result of human activities. Poverty and desertification in dryland areas are major problems threatening sustainable agriculture and rural development in dryland areas. Several topics that are significant for sustainable agriculture and rural development for food security and environmental rehabilitation in dryland areas were stressed in this paper.
Full Text Available Agricultural development thinking has gone through several stages of fad and fancy, often without an understanding of previous fallacies. Its current doldrums are unfortunate given the unrivaled importance of agricultural development for poverty reduction in most development countries. After reviewing several policy and program areas, lessons are synthesized, and a forward-looking research framework suggested, especially regarding role of specialization in the evolution of economic organization. The corresponding role of government is seen to be the facilitation of economic cooperation, rather than social engineering.
Full Text Available In Ivory Coast, the freshwater fishculture in rural areas is mainly on a small scale. This type of breeding in ponds (2 to 4 ares yields on an average 3 metric tons of fish/ha/year and represents only an activity with self-consumption of products. The yield in intensive pond fishculture Tilapia nilotica is on an average 6 to 7 metric tons/ha/year but yields bigger than 10 metric tons/ha/year are not uncommon. The intensive fishculture in floating cages, requiring a minor investment but a more improved formation than in fischculture, yields on an average about 30 to 40 kg/m3/year. However the effective development of this activity rests on the resolution of problems like the sufficient fry production, the feeding and the commercialization.

Full Text Available The new advances in biotechnology, especially in the completion of the Arabidopsis thaliana, genome sequence has profound implications for human health as well as plant biology and agriculture. It will permit us to know the action of all the genes involved in the key growing and development processes of plants. Modification of the structure of genes will allow the regulation of the expression of some characteristics such as the size of the leaves or the dynamics of the roots and fruits growth. In this way, the commercialization of the products of the new biotechnologies will influence in this century´s nations, agricultural production, productivity and food supply. The challenges and opportunities for the countries of Latin America and the Caribbean (LAC are enormous, due to the rich base of their flora, fauna and microorganisms resources, which are essential to the pharmaceutical and feeding industries. The international Community recognizes the benefits of Biotechnology, but it also advocate more inquiry into the impacts of advanced agricultural biotechnologies on the environment, food system, structure of agriculture, rural communities, and population health.The countries of LAC should continue the development and improvement of the regulatory framework for preventing or minimizing the possible risks of the use and management of the transgenic organisms in their territory, and therefore, be able to make use of their potential benefits, ensuring the protection of public health and the environment.
In 2012,China’s total grain yield reached 590 million tons and realized nine consecutive years of growth. This is huge historic achievement of China and also rare in development history of world agriculture. However,at the same time of making great achievements,China’s agriculture is still confronted with many problems. On the basis of extensive survey,it pointed out 10 outstanding problems: farmland,labor,livestock power,water conservancy,input,agricultural disaster,ecological and environmental problem,waste of resources,economic scale and economic benefits. These problems have brought great adverse influence on China’s agricultural development. In view of these problems,to realize sustainable,stable and healthy development of agriculture in the new period,it came up with following recommendations:( i)deepening the understanding;( ii) enforcing laws strictly;( iii) enhancing training;( iv) increasing benefits;( v) saving resources;( vi) protecting environment;( vii) developing science and technology;( viii) consolidating foundation.

Full Text Available The agricultural sector as one of the most important sectors in the process of development has always had a special status in world economy. However, relative decrease of the share of agriculture over the recent decades often leads one to believe that agriculture can be ignored in favor of those sectors which have a faster progress, whereas, on the contrary, in order to accelerate favorable economic transition agriculture must be encouraged. Therefore, this research seeks to study the role and effect of the agricultural sector in comparison to other sectors such as industry, services, mining and commerce on variables such as GDP, the remnant of bank facilities and credit organizations, total petroleum exports in Iran during the past 15 years. Research methodology is applied and of descriptive-correlational type. Data collection tool is previous documents and evidence. Data analysis method is step-by-step regression. The results of the research indicate that in the first, second and third regression models agriculture respectively has the third, first and second status in regard to level of effectiveness.

Full Text Available Based on the usage of multiple sources of literature in this paper, a review of the most important characteristics is made along with the comparison of functions related to agricultural insurance in Croatia. Larger part of this paper is about comparison of offers and the ways agricultural insurance is being subsided in developed countries of the EU and USA on one hand, and Croatia on the other. Also, a display of risk coverage is made, along with the subsidization of the country and the way insurance system functions in Spain (country with the most developed security in Europe, Portugal, Italy, Austria and France. Main characteristic of the agricultural insurance in Croatia is a weak offer from the insurance companies, but also a weak demand. Therefore, only four companies can insure crops and plantations in Croatia. Although risk is unavoidable, negative impacts can be reduced with well-timed reaction and responsible organisation.

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.

Full Text Available This paper analyzed an opportunity of rural farmers in north of Thailand by interviewing 124 households which were 59 families from Tumbon-Santa Aumpor- Narnoi Nan province, 23 families from Tumbon-Banlao Aumpor-Mayjai Prayao Province, 22 families from Tumbon-Sritoi Aumpor-Mayjai Prayao Province, and 20 families from Tumbon-Parfak Aumpor-Mayjai Prayao Province during January 2012 – October 2012. Probit model was developed to answer some factors that impacted farm’s income. The results showed that the relationships between both organic and inorganic land and income level are positive. Most of the farmers were willing to change from conventional agricultures to organic agriculture but they did not have enough information and extension from government and private sectors. Comparing benefits and cost between conventional and organic agriculture found that organic agricultures provided better price and farmers will have better quality of live. Systems of knowledge and policies need to be developed and apply for peasants and farmers in north rural area in Thailand.

As a part of certain region,agricultural development has inevitable connection with regional urbanization,and they are highly heterogeneous and complementary in space. Their internal relationship is manifested as agricultural structure suits demand of urbanization development through adjustment in the process of urbanization,while urbanization is based on development of regional agriculture. From history of world agriculture and urbanization development,agriculture firstly provides primitive accumulation for urbanization development,and drives regional urbanization through promoting agricultural development. When urbanization develops to certain stage,urbanization accumulation increases and reaches the goal of " boosting urbanization through agriculture". If urbanization develops slowly,agricultural adjustment will lack motive force. On the contrary,weak agricultural development will lead to stagnation of urbanization. Therefore,adjustment of agricultural structure and urbanization development are interconnected,mutually promoted and restricted,and interdependent.

The U.S. Geological Survey and the National Park Service conducted a reconnaissance study to investigate the occurrence of selected human-health pharmaceutical compounds in water samples collected from Lake Mead on the Colorado River and Las Vegas Wash, a waterway used to transport treated wastewater from the Las Vegas metropolitan area to Lake Mead. Current research indicates many of these compounds can bioaccumulate and may adversely affect aquatic organisms by disrupting physiological processes, impairing reproductive functions, increasing cancer rates, contributing to the development of antibiotic-resistant strains of bacteria, and acting in undesirable ways when mixed with other substances. These compounds may be present in effluent because a high percentage of prescription and non-prescription drugs used for human-health purposes are excreted from the body as a mixture of parent compounds and degraded metabolite compounds; also, they can be released to the environment when unused products are discarded by way of toilets, sinks, and trash in landfills. Thirteen of 33 targeted compounds were detected in at least one water sample collected between October 2000 and August 2001. All concentrations were less than or equal to 0.20 micrograms per liter. The most frequently detected compounds in samples from Las Vegas Wash were caffeine, carbamazepine (used to treat epilepsy), cotinine (a metabolite of nicotine), and dehydronifedipine (a metabolite of the antianginal Procardia). Less frequently detected compounds in samples collected from Las Vegas Wash were antibiotics (clarithromycin, erythromycin, sulfamethoxazole, and trimethoprim), acetaminophen (an analgesic and anti-inflammatory), cimetidine (used to treat ulcers), codeine (a narcotic and analgesic), diltiazem (an antihypertensive), and 1,7-dimethylxanthine (a metabolite of caffeine). Fewer compounds were detected in samples collected from Lake Mead than from Las Vegas Wash. Caffeine was detected in all samples

The aim of the article is an analysis of technological aspects of leasing application for agricultural enterprises in the context of complex innovative development of agrarian sphere.The results of the analysis. It is shown that the latest technology and recovery techniques must be at all stages of the agricultural sector. The first stage is selection of breeding. The last is sale of agricultural products. Asset structure of agricultural enterprises occupies about one third of machines and equipment, which are now physically and morally outdated. Authors of the article analyze the technological aspect of leasing and prove that leasing of biological assets and leasing equipment should be considered separately, which are more consistent with the structure of the innovation needs of agricultural businesses (purchase of machinery and equipment, research and development, acquisition software and industrial design. Innovative technologies and leasing are proposed to be considered in the context of the eco-village system to ensure maximum utilization of all natural resources: low-temperature heat of the earth, air and water (heat pumps, alternative energy (solar, biomass, wind, water, etc., not carbon motor fuel (biogas, air, electricity, new modes, innovative agricultural technologies, safe disposal of solid waste of local wastewater treatment (biological, resonance, mechanical, technologies in the construction and infrastructure development.

Using modern economic theories,this paper analyzed drawbacks of Shareholding cooperative development of agricultural cooperatives in institutional design and expounded inevitable difficulties of development of agricultural cooperatives. Shareholding cooperative development provides a pass for many social forces entering and controlling agricultural cooperatives and making numerous non-agricultural cooperative organizations become formal cooperatives. Deep cause for Shareholding cooperative development of agricultural cooperatives involves how to recognize status and function of family producers of agricultural products in the drive of agricultural modernization and the problem of state policies choosing family producers of agricultural products or other participants in the agricultural industry chain. Shareholding cooperative development is only an expedient measure in certain period,and it should not change development laws of things and essential feature of agricultural cooperatives because of stressing national conditions.

Full Text Available This article is devoted to the theoretical and practical aspects of development of the property relations in rural household in the context of regional characteristics. Based on generalizations, theoretical approaches for the interpretation of the term "region" are given by its definition as territorial and specialized part of the economic sector of the country, which is characterized by the presence of a subject endowed with appropriate powers, interdependent unity of the natural, historical, geographical, economic and social factors. In terms of regions, there had been studied the dynamics of gross agricultural production in terms of value and also changes in the number of agricultural enterprises during the pre- and post reform periods of the property relations. It turned out that regionalization within the boundaries of the state reflects all the administrative-territorial units, which, holding a certain economic independence and managerial competence, acts as an important factor influencing on the development of economic processes, including on the property relations in agriculture
Full Text Available A spatiotemporal analysis on the changes in the marsh landscape in the Honghe National Nature Reserve, a Ramsar reserve, and the surrounding farms in the core area of the Sanjiang Plain during the past 30 years was conducted by integrating field survey work with remote sensing techniques. The results indicated that intensified agricultural development had transformed a unique natural marsh landscape into an agricultural landscape during the past 30 years. Ninety percent of the natural marsh wetlands have been lost, and the areas of the other natural landscapes have decreased very rapidly. Most dry farmland had been replaced by paddy fields during the progressive change of the natural landscape to a farm landscape. Attempts of current Chinese institutions in preserving natural wetlands have achieved limited success. Few marsh wetlands have remained healthy, even after the establishment of the nature reserve. Their ecological qualities have been declining in response to the increasing threats to the remaining wetland habitats. Irrigation projects play a key role in such threats. Therefore, the sustainability of the natural wetland ecosystems is being threatened by increased regional agricultural development which reduced the number of wetland ecotypes and damaged the ecological quality.

The Kilombero Valley lies at the intersection of a network of protected areas that cross Tanzania. The wetlands and woodlands of the Valley, as well as the forest of surrounding mountains are abundant in biodiversity and are considered to be critical areas for conservation. This area, however, is also the home to more than a half million people, primarily poor smallholder farmers. In an effort to support the livelihoods and food security of these farmers and the larger Tanzanian population, the country has recently targeted a series of programs to increase agricultural production in the Kilombero Valley and elsewhere in the country. Bridging concepts and methods from land change science, political ecology, and sustainable livelihoods, I present an integrated assessment of the linkages between development and conservation efforts in the Kilombero Valley and the implications for food security. This dissertation uses three empirical studies to understand the process of development in the Kilombero Valley and to link the priorities and perceptions of conservation and development efforts to the material outcomes in food security and land change. The first paper of this dissertation examines the changes in land use in the Kilombero Valley between 1997 and 2014 following the privatization of agriculture and the expansion of Tanzania's Kilimo Kwanza program. Remote sensing analysis reveals a two-fold increase in agricultural area during this short time, largely at the expense of forest. Protected areas in some parts of the Valley appear to be deterring deforestation, but rapid agricultural growth, particularly surrounding a commercial rice plantation, has led to loss of extant forest and sustained habitat fragmentation. The second paper focuses examines livelihood strategies in the Valley and claims regarding the role of agrobiodiversity in food security. The results of household survey reveal no difference or lower food security among households that diversify their

The study is a geohydrologic reconnaissance of about 170 square miles in the Lake Mead National Recreation Area from Las Vegas Wash to Opal Mountain, Nevada. The study is one of a series that describes the geohydrology of the recreation area and that indentifies areas where water supplies can be developed. Precipitation in this arid area is about 5 inches per year. Streamflow is seasonal and extremely variable except for that in the Colorado River, which adjoins the area. Pan evaporation is more than 20 times greater than precipitation; therefore, regional ground-water supplies are meager except near the Colorado River, Lake Mead, and Lake Mohave. Large ground-water supplies can be developed near the river and lakes, and much smaller supplies may be obtained in a few favorable locations farther from the river and lakes. Ground water in most of the areas probably contains more than 1,000 milligrams per liter of dissolved solids, but water that contains less than 1,000 milligrams per liter of dissolved solids can be obtained within about 1 mile of the lakes. Crystalline rocks of metamorphic, intrusive and volcanic origin crop out in the area. These rocks are overlain by conglomerate and mudstone of the Muddy Creek Formation, gravel and conglomerate of the older alluvium, and sand and gravel of the Chemehuevi Formation and younger alluvium. The crystalline rocks, where sufficiently fractured, yield water to springs and would yield small amounts of water to favorably located wells. The poorly cemented and more permeable beds of the older alluvium, Chemehuevi Formation, and younger alluvium are the better potential aquifers, particularly along the Colorado River and Lakes Mead and Mohave. Thermal springs in the gorge of the Colorado River south of Hoover Dam discharge at least 2,580 acre-feet per year of water from the volcanic rocks and metamorphic and plutonic rocks. The discharge is much greater than could be infiltrated in the drainage basin above the springs

This article presents the development of an advanced adsorption desalination system with quantum performance improvement. The proposed multi-effect adsorption desalination (MEAD) cycle utilizes a single heat source i.e., low-temperature hot water (as low as 55°C). Passive heating of the feed water (no direct heating) is adopted using total internal heat recovery from the kinetic energy of desorbed vapor and water vapor uptake potential of the adsorbent. Thus, the evaporation in the MEAD cycle ensues at low temperatures ranging from 35°C to 7°C yet providing significantly high performance ratio. The energy from the regenerated vapor is recovered for multiple evaporation/condensation of saline water by a water-run-around circuit between the top brine temperature (TBT) effect and the AD condenser. The adsorbent material is the hydrophilic mesoporous silica gel with high pore surface area. Numerical simulation for such a cycle is developed based on experimentally verified model extending to multi-effect cycle. The system is investigated under several operation conditions such as cycle time allocation, heat source temperature and the number of intermediate effects. It is observed that most of the evaporating-condensing effects operate at low temperature i.e., below 35°C as opposed to conventional multi-effect distillation (MED) cycle. For a MEAD cycle with 7 intermediate effects, the specific water production rate, the performance ratio and the gain output ratio are found to be 1.0m3/htonne of silica gel, 6.3 and 5.1, respectively. Low scaling and fouling potentials being evaporation at low temperatures yet high recovery ratio makes the cycle suitable for effectively and efficiently handling highly concentrated feed water such as produced water, brine rejected from other desalination plants and zero liquid discharge (ZLD) system. © 2015 Elsevier Ltd.

Agricultural biotechnology holds much potential to contribute towards crop productivity gains and crop improvement for smallholder farmers in developing countries. Over 14 million smallholder farmers are already benefiting from biotech crops such as cotton and maize in China, India and other Asian, African and Central/South American countries. Molecular breeding can accelerate crop improvement timescales and enable greater use of diversity of gene sources. Little impact has been realized to date with fruits and vegetables because of development timescales for molecular breeding and development and regulatory costs and political considerations facing biotech crops in many countries. Constraints to the development and adoption of technology-based solutions to reduce yield gaps need to be overcome. Full integration with broader commercial considerations such as farmer access to seed distribution systems that facilitate dissemination of improved varieties and functioning markets for produce are critical for the benefits of agricultural biotechnology to be fully realized by smallholders. Public-private partnerships offer opportunities to catalyze new approaches and investment while accelerating integrated research and development and commercial supply chain-based solutions.

According to the viewpoints of predecessors, we define the signification of development right of agricultural land and connotation of the price of development right of agricultural land as follows: the development right of agricultural land is to change the former use nature of agricultural land, so as to become the right of construction use land; the price of development right of agricultural land refers to the price that is difference between the price of construction use land, and summation of the price of former agricultural land, the expense of developing agricultural land, the expense of management, and profit, after the agricultural land is transformed into non-agricultural construction use land. By using the principle of economics of land, this paper expounds the generation mechanism of the price of development right of agricultural land, namely the diversity of agricultural land use and the change of demand and supply of development right of agricultural land. The influencing factors of the development right of agricultural land are analyzed, and there are mainly the price of agricultural land, the price of construction use land, the contradiction of demand and supply of urban land, land use, and agricultural land.

Culp, Elzie Lynn [Surprise Valley Electrification Corp., Alturas, CA (United States)
Surprise Valley Electric, a small rural electric cooperative serving northeast California and southern Oregon, developed a 3mw binary geothermal electric generating plant on a cooperative member's ranch. The geothermal resource had been discovered in 1980 when the ranch was developing supplemental irrigation water wells. The 240°F resource was used for irrigation until developed through this project for generation of electricity. A portion of the spent geothermal fluid is now used for irrigation in season and is available for other purposes, such as greenhouse agriculture, aquaculture and direct heating of community buildings. Surprise Valley Electric describes many of the challenges a small rural electric cooperative encountered and managed to develop a geothermal generating plant.

Full Text Available Based on the share of agriculture in GDP in Uzbekistan, the country can be allocated to a group of countries with a transitional type of economy that proceeds from agriculture to urbanization. At the same time specific local features exist. In Uzbekistan, about 65% of the population live in rural areas and currently about 3 million people are employed in agriculture. Although the trend shows a decline in the share of agriculture in gross domestic product, the number of people employed in agriculture has comparably slowly reduced. Agriculture's share of investment is only about 3-4% of the total amount of a fixed capital.

in the world market could increase pressure to slacken regulatory requirements on agriculture. Thus, the question of whether liberalization will hinder or promote environmentally sustainable production methods in agriculture is unresolved. This paper analyses different scenarios of agricultural policy......Recent reforms of the European Union’s Common Agricultural Policy (CAP) have set in motion a process of increased market orientation in the agricultural sector, a process that will be intensified by trade liberalization if an agreement is reached under the World Trade Organization (WTO......). It is widely expected that both CAP reforms and a WTO agreement will also lead to a more environmentally friendly European agriculture. It is conceivable, however, that market demand would instead provide renewed incentives for intensive agricultural production. Opening European agriculture to more competition...

The green revolution of the 1960s and 1970s which resulted in dramatic yield increases in the developing Asian countries is now showing signs of fatigue in productivity gains. Intensive agriculture practiced without adherence to the scientific principles and ecological aspects has led to loss of soil health, and depletion of freshwater resources and agrobiodiversity. With progressive diversion of arable land for non-agricultural purposes, the challenge of feeding the growing population without, at the same time, annexing more forestland and depleting the rest of life is indeed daunting. Further, even with food availability through production/procurement, millions of marginal farming, fishing and landless rural families have very low or no access to food due to lack of income-generating livelihoods. Approximately 200 million rural women, children and men in India alone fall in this category. Under these circumstances, the evergreen revolution (pro-nature, pro-poor, pro-women and pro-employment/livelihood oriented ecoagriculture) under varied terms are proposed for achieving productivity in perpetuity. In the proposed 'biovillage paradigm', eco-friendly agriculture is promoted along with on- and non-farm eco-enterprises based on sustainable management of natural resources. Concurrently, the modern ICT-based village knowledge centres provide time- and locale-specific, demand-driven information needed for evergreen revolution and ecotechnologies. With a system of 'farm and marine production by masses', the twin goals of ecoagriculture and eco-livelihoods are addressed. The principles, strategies and models of these are briefly discussed in this paper.

Circular agriculture helps to solve the drawbacks of traditional agricultural production and achieve unified economic and ecological benefits,consistent with the concept of sustainable development.Based on the theoretical perspective of circular agriculture,this paper builds the evaluation indicator system for circular agriculture in Sichuan Province,and uses the coefficient of variation to evaluate the current situation of development of circular agriculture in Sichuan Province from 2000 to 2012.Then it analyzes the obstacles to the development of circular agriculture in Sichuan Province in 2012,and sets forth the targeted recommendations.
On the basis of the concept and characteristics of circular economy, this paper analyzes the restraining factors of China’s circular agricultural development as follows: issues concerning agriculture, countryside and farmers are outstanding; the problems of agricultural resources and agricultural ecological environment are serious; the quality of agricultural products cannot meet the demand of domestic and international market for food. Based on the internal requirements of low carbon economic development, this paper advances four innovative models concerning China’s circular agricultural development as follows: the model of combining planting and breeding of agriculture, the developmental model of leisure and sightseeing, ecological integration model, and the developmental model of reusing agricultural byproducts. Every region should choose or create different circular agricultural model in different domains, in order to better use agricultural resources, reduce the consumption of agricultural energy inputs, reduce the emission of agricultural greenhouse gas, develop low carbon agriculture, and make great contribution for meeting the international challenges and promoting China’s agricultural development.

Traditional rice-fish agricultural heritage site in Qingtian County, China, one of the pilot sites of Glob-ally Important Agricultural Heritage Systems (GIAHS), is of great value in tourism development. This paper aims to explore how to realize sustainable tourism development in agricultural heritage site through identifying current problems in GIAHS site, and making constructive recommendations for coupled development of heritage preserva-tion and economic development. Field survey was carried out and data was collected through field questionnaire surveys of tourists and residents' in Longxian Village of Qingtian County, as well as interviews of residents with semi-structured questionnaires for their perceptions and attitudes to tourism development. The following results are got.(1) the tourism industry is still at its early state of Nongjiale tourism (enjoy and experience authentic country life-style), under very limited administrative management; (2) what attracts visitors most are delicious fish and beautiful natural environment, but not agricultural heritage itself; (3) most tourists come from adjacent areas and stay only half a day, many of whom pay their visits twice or more; (4) a few local residents take part in the activities of tourism industry, but in very limited manners even if they do.Current patterns of tourism development are casting negative impacts on agricultural heritage. Conservation agricultural heritage should be put in the first place for sustainable tourism development. Agricultural heritage, as a key attraction, should be taken as the focus for tourism development. The important thing is to change the present Nongjiale tourism into real heritage tourism, to establish a cooperative mechanism among different stakeholders,and to increase local residents' income through engaging in tourism industry.

The analysis is based on the classification of agricultural policy and its measures, standard indicators used for analysis of development of agricultural policy and agriculture, and specific methods for evaluating the efficiency of agricultural policy (evaluation methods, simulation methods. The results show that the transition in Slovenia caused no marked shocks for agricultural production. The development goals for agriculture were set forth early (in 1992 and were modeled on the EU standards, and they remained unchanged throughout the transition. A protectionist development concept of agricultural policy was adopted, which assured a relatively high level of support to agriculture. Under this concept, the agricultural policy was substantially reoriented during the transition, but this happened gradually and was reflected above all in the re-instrumentation of policy and changes of the structure of support to agriculture. Agricultural policy was relatively successful. It managed to achieve most of the strategic development goals of agriculture and a high degree of compatibility with the Common Agricultural Policy (CAP.

Full Text Available Rural development includes local population, its way of life, employment characteristics, income structure, dwelling conditions, service levels as well as cultural aspects just as traditional handcrafts, dishes, language, clothing and habits. Since agriculture is a historically determining economic activity in rural areas its effects primarily determines the rural ways of life. New rural development policy of EU can be featured by multisectoral and integrated approach. Organic farming is based on the definition of ecology as former namings just as ˝ecological˝, ˝biological˝ represent it. Its basic aim is ensuring sustainable development whereas it uses again, from time to time to locally available reserves. Among basic principles of organic farming can be found the protection of soil and environment and this implies the usage of natural capacities of plants, animals and the landscape and willingly tries to improve the quality of the environment. It can be stated that market demand for organic products is the strongest in Europe, as much as 46% of the world´s organic product output is sold in this continent which possibly can be explained by its economic development level. This overall development reached Hungary, too. In December 2002 the estimations showed 105.000 ha and within this 54.497 ha had been registered as approved organic area. During the last year we carried out two focus group analyses examining the reasons for buying or not buying organic foods. In the presentation the most important results of the two focus groups will also be introduced in details.

In June and July 2006 a team of outside experts arrived in Yei, Southern Sudan through an AID project to provide support to a local agricultural development project. The team brought evaluation, agricultural marketing and financial management expertise to the in-country partners looking at steps to rebuild the economy of the war ravaged region. A partnership of local officials, agricultural development staff, and students worked with the outside team to craft a survey of agricultural traders working between northern Uganda and Southern Sudan the steps approach of a collaborative model. The goal was to create a market directory of use to producers, government officials and others interested in stimulating agricultural trade. The directory of agricultural producers and distributors served as an agricultural development and promotion tool as did the collaborative process itself.
Under the premise of unchanging the collective ownership and the mode of family business, China should choose land shares pack system as the goal pattern of farmland system innovation.It is hoped that the pattern is accepted and supported by both sides of the government and the farmers,and then it constructs the land reasonable circulation and the effective centralism mechanism, thus realizing smooth transition from the traditional agriculture to the modern agriculture.

Perhaps every generation of astronomers believes that their telescopes are the best that have ever been. They are surely all correct! The great leap of our time is that computer-designed and machined parts have led to more accurately made components that give the astronomer ever better views. The manual skills of the craftsman mirror grinder have been transformed into the new-age skills of the programmer and the machine maker. (The new products did not end the work of craftsman telescope makers, though. Many highly skilled amateur/professional opticians continued to produce good-quality mirrors that are still seen today.) Amateur-priced telescopes are now capable of highly accurate tracking and computer control that were once only the province of professionals. This has greatly increased the possibilities of serious astronomy projects for which tailor-made software has been developed. Add a CCD camera to these improved telescopes (see Chap. 3), and you bring a whole new dimension to your astronomy (see Fig. 1.1).
Evaluation index system of agricultural sustainable development is constructed with the four components of social index,agricultural economic index,resources index,and environment index.According to the comprehensive evaluation model of agricultural sustainable development with the participation of single person,comprehensive evaluation model of agricultural sustainable development with the smallest generalized deviation and the participation of many people is established.Based on the case studies,agricultural sustainable development status of a certain region is evaluated.Result shows that the evaluation scores of the social index and agricultural economic index are high in this region,but the score of resources index is general and the evaluation result of environment index is not very good.The comprehensive evaluation value of overall sustainable development is 0.665 5;and the evaluation result is "good".

Full Text Available Agriculture is an important field and also a priority of Romania's development. In this regard, providing food for population is a factor that ensures the specificity of agriculture. For this reason, we can consider that agriculture is a starting point for the socio-economic development of the country. Romania is recognized, at European and international level, for its experience in cultivating natural and traditional products. The agricultural area offers the possibility of supplying raw materials for both the population and for the manufacturing industry. It is aimed that the organization of the agricultural area to be made so that the lands that have agricultural destination to be used as rationally as possible. Also, it is important to introduce in the agricultural circuit all the unused lands. The fragmentation of the agricultural land is a disadvantage in the process of rational organization of agricultural area. Efficient use of land, as a requirement of the intensive and durable agriculture is a complex activity that involves conservation activities and soil improvement. Due to the role that they have, the approach of the aspects referring to the medium and big farms has to be different from the approaches referring to the small farms. If the farms from the first category take into account the agriculture as a business, the small farms are important for the rural area by oferring food and social security and means of traditional production that contributes to the environment conservation. Romania's economic recovery can be achieved based on the attention that has to be given to this field. Being an important factor of social stability and of the maintainance of the ecological balance, agriculture enjoys an increasing attention worldwide. The supply and the demand of food determines the use of agricultural resources. The article presents the current situation of agriculture, at national and regional levels. Through this analysis, we

The worldwide increase in human population raises a big threat to the food security of each people as the land for agriculture is limited and even getting reduced with time. Therefore, it is essential that agricultural productivity should be enhanced significantly within the next few decades to meet the large demand of food by emerging population. Not to mention, too much dependence on chemical fertilizers for more crop productions inevitably damages both environmental ecology and human health with great severity. Exploitation of microbes as biofertilizers is considered to some extent an alternative to chemical fertilizers in agricultural sector due to their extensive potentiality in enhancing crop production and food safety. It has been observed that some microorganisms including plant growth promoting bacteria, fungi, Cyanobacteria, etc. have showed biofertilizer-like activities in the agricultural sector. Extensive works on biofertilizers have revealed their capability of providing required nutrients to the crop in sufficient amounts that resulted in the enhancement of crop yield. The present review elucidates various mechanisms that have been exerted by biofertilizers in order to promote plant growth and also provides protection against different plant pathogens. The aim of this review is to discuss the important roles and applications of biofertilizers in different sectors including agriculture, bioremediation, and ecology.
Full Text Available Important green house gases (GHG attributed to animal agriculture are methane (CH4 and nitrous oxide (N2O, though carbon dioxide (CO2 contributes almost half of total greenhouse effect. Rumen CH4 production in an enteric fermentation can be accounted as the biggest anthropogenic source. Some of prebiotics and probiotics have been innovated to mitigate rumen CH4 emission. The possible use of agricultural biomass consisted of non-edible parts of crop plants such as cellulose and hemi cellulose and animal wastes was proposed as a renewable energy and nitrogen sources. The ammonia stripping from digested slurry of animal manure in biogas plant applied three options of nitrogen recycling to mitigate nitrous oxide emission. In the first option of the ammonia stripping, the effect of ammonolysis on feed value of cellulose biomass was evaluated on digestibility, energy metabolism and protein utilization. Saccharification of the NH3 treated cellulose biomass was confirmed in strictly anaerobic incubation with rumen cellulolytic bacteria, Ruminoccous flavefaciens, to produce bio-ethanol as the second option of ammonia stripping. In an attempt of NH3 fuel cell, the reformed hydrogen from the NH3 stripped from 20 liter of digested slurry in thermophilic biogas plant could generate 0.12 W electricity with proton exchange membrane fuel cell (PEM as the third option.
The gap between urban and rural incomes in Guangxi is increasing year by year in a rising tendency,which resulted in agricultural development impact cannot be ignored.Such impact on agricultural development was analyzed from three aspects:agricultural development fund,farmland and food problems and labor force flow.The following problems were found:capitals flew to non-agricultural industry,which resulted in deficiency of agricultural development fund;farmland reduced and the problem of food supply was highlighted;labor force in rural areas emigrated,the price of agricultural products rose up.Related policies were offered:to strengthen the financial support;to speed up utilization of abundant labor force;to motivate farmers’ enthusiasm in food production;to increase investment in farmers’ endowment insurance and retirement pension in rural areas.
Full Text Available The scientific substantiation of accommodation of an agricultural production of territorial divisions of region is a complex social-economic problem. The decision of this problem demands definition market-oriented criteria of an optimality. The author considers three criteria of optimality: maximum of profit; maximum of gross output without production costs and costs for soil fertility simple reproduction; maximum of marginal income. Conclusion is drawn that the best criterion of optimization of production is the maximum the marginal income (the marginal income without constant costs, which will raise economic and ecological efficiency of an agricultural production at all management levels. As a result of agricultural production optimization the Republic Bashkortostan will become self-provided and taking out (foodstuffs region of Russia. In this case the republic is capable to provide with food substances (protein, carbohydrates and etc. 5.8 – 6.5 million person. It exceeds a population of republic on 40 – 60 %.
We take the case of Qianjin Village,Jiangxia District,Wuhan City,to research how to establish the system of urban agriculture with distinctive features relying on the advantage of urban resources.Under the guidance of guiding ideology,basic principles and overall objectives of urban agriculture development planning,we analyze the specific construction planning of urban agriculture in Qianjin Village,mainly including the construction of growing areas and construction of leisure areas.Then we put forth the security system of development of urban agriculture as follows: land transfer is the prerequisite of development of urban agriculture;policy support is the important foundation of development of urban agriculture; agricultural science and technology is strong support for development of urban agriculture;good leadership is the organizational guarantee for development of urban agriculture;the industrialization of agriculture is the main objective of development of urban agriculture.
By selecting the panel data from 2001 to 2008 in central and western regions,I adopt the methods of covariance analysis test,Hausman test,panel unit root test and co-integration test to conduct empirical research on the interactive relationship between agricultural insurance and rural financial development in central and western regions.The results show that there is a long-term balanced and interactive causal relationship between agricultural insurance and rural financial development in central and western regions.The agricultural insurance in western regions is the cause of rural financial development,while such relationship in central regions is not tenable.There is an interactive promotion relationship between agricultural insurance and rural financial development efficiency in central regions,while the relationship between agricultural insurance and rural financial development efficiency in western regions is mutually inhibitive,but the rural financial efficiency in western regions promotes the development of agricultural insurance.Then corresponding suggestions are put forward in order to give full play to the role of mutual promotion between agricultural insurance and rural financial development as follows:reinforce the support degree for policy finance in central and western regions;increase the inputs of rural financial institutions in serving agriculture,countryside and farmers;expand the types and coverage of policy agricultural insurance.

To understand the spatial difference of agricultural sustainability in Tibet,this paper establishes a comprehensive evaluation model of agricultural sustainability to calculate the score of agricultural sustainability of 7 areas in 2013 in Tibet. By using cluster analysis,this paper conducts the regional evaluation of Tibet’s agricultural sustainability. The results show that 7 cities’ regional difference of agricultural sustainability was obvious in 2013,the agricultural sustainability index value was 0. 4232- 0. 6937,and the value was in the order of Nyingchi > Lhasa > Shannan > Ali > Shigatse > Qamdo > Nagqu. According to the agricultural sustainable development level,Tibet can be divided into three regions: the first type is the area with the highest level of sustainable development of agriculture,including Nyingchi and Lhasa; the second type is the area with the average level of sustainable development of agriculture,including Shigatse and Shannan; the third type is the area with the low level of sustainable development of agriculture,including Qamdo,Ali and Nagqu.

This brief article looks at the intersection of climate, land cover/land use, and population trends in the world's most food insecure country, Ethiopia. As a result of warming in the Indian and Western Pacific oceans, Ethiopia has experienced substantial drying over the past 20 years. We intersect the spatial pattern of this drying with high resolution climatologies, maps of agricultural expansion, population data, and socioeconomic livelihoods information to suggest that the coincidence of drying and agricultural expansion in south-central Ethiopia is likely adversely affecting a densely populated region with high levels of poverty and low wage levels.
Full Text Available Research results presented in this paper refer to changes in the structure of the agricultural population of the Pčinja District in the period from 1971 to 2002. They point to markedly decrease in the agricultural population, the share of agricultural population in total population, the share of rural population in total population, as well as the share of active agricultural population in total active population. The process of deagrarianization in this area is a constraining factor for the development of agriculture and causes spontaneous abandonment by working-age population who is employing in other sectors. Transfer of agricultural population in non-agricultural activities takes place either by moving into the city centre or by remaining in agricultural households and employing in non-agricultural activities (which causes daily rural-urban migration. The process of depopulation and deruralization caused ageing population to be involved in agriculture in many rural settlements so that the effects of agricultural production have become significantly decreasing. To eliminate the negative effects of the regional development of the Pčinja District, it is necessary to establish and implement a functional demographic policy and concept of the revitalization of rural area.
From the perspective of economic growth,agricultural development,the development of township enterprises and farmers’ income,we select 11 indicators to build the evaluation indicator system for the agricultural economic development in the districts and counties of Qingyang City. Using data processing and SPSS13. 0 statistical software,we carry out the cluster analysis of the level of economic development in the districts and counties,and divide the level of agricultural economic development of these districts and counties into three economic gradients in descending order:(i) The first gradient: Xifeng;(ii) The second gradient: Qingchi and Huachi;(iii) The third gradient: Huanxian,Heshui,Zhengning,Ningxian and Zhenyuan. The study results systematically reflect the level of agricultural economic development in the districts and counties,and point out the status of the districts and counties in Qingyang’s agricultural economic development. Finally we put forth the corresponding recommendations.
Based on the provincial units evaluation, this paper makes an assessment for sustainable developingcapability of the integrated agricultural regionalization in China. At first, an index system of agricultural sustainabledevelopment in China is built up, which includes 5 supporting subsystems of agricultural resources, agricultural develop-ment, environment and ecosystem, rural society, sciences-education and management. We selected 95 factors on provin-cial level as basic indexes. Second, a relative assets/debt assessing method is used to gain relative net assets values(relative superiority) of every provincial unit, which are as supporting data for assessment. We also overlaid the Administra-tive Divisions Map of China and the Map of Integrated Agricultural Regionalization of China by Geography Information Sys-tem (GIS) to gain the area units of assessment. Third, according to the relative coherence principle of regionalization,we transform administration units to natural units through homogenizing all provincial relative net assets values in everyagricultural assessing unit. After making order and grade, we complete the sustainable developing capability assessmentto integrated agricultural regionalization in China. The assessing outcome shows that the total sustainable agricultural develop-ing capability of China is not high. Only about 1/3 in number or in area has reached the level of agricultural sustainabledevelopment. The relative net assets values exists a reducing trend from East China to West China. It needs a long periodand great efforts to realize sustainable agricultural development over all China. Finally, there is a discussion to the studymethod.
By using the grey relational model,14 indexes of ecological agricultural development in Sichuan Province from 1997 to 2008 are analyzed.According to the relational degree results,the ecological agricultural development in 12 years can be divided into three stages:the first stage is from 1997 to 2000,with the shape of inverted U;the second stage is from 2001 to 2004,belonging to transition stage with slow growth rate;the third stage is from 2005 to 2008,belonging to the stage of rapid growth.It draws conclusion that per capita grain yield is an important element for evaluating ecological agricultural construction.Besides,reducing the energy consumption of per unit production,improving labor productivity and increasing agricultural science and technology application and input on agricultural infrastructure construction are the engine for developing Sichuan ecological agriculture.

Taking Zhangye City as an example, the thesis analyzes the restricted factors of resources and environment confronted by the agriculture in arid area of Hexi Corridor: the first is the agricultural natural resources. The area of cultivated land decreases year by year, and there are sharp decrease of biological diversity as well as the shortage and waste of water resources; the second is the ecological environment. There are critical soil erosion, frequent natural disaster and outstanding agricultural area source pollution; the third is the rural economy. The agricultural structure still can not meet the need of agricultural development in recent years, and the proportion of agricultural product processing is low. It points out that implementation of agricultural recycle economy is the necessary choice of the agricultural development in Zhangye City. Developing recycle economy is conducive to improving ecological environment and realizing agricultural sustainable development; developing recycle economy can solve the agricultural area source pollution to much extent and protect rural environment; developing recycle economy is conducive to adjusting rural industrial structure, increasing job opportunities and increasing farmers’ income; developing recycle economy is conducive to elevating the international competitiveness of agricultural products. The thesis also has put forward the countermeasures of developing agricultural recycle economy in Zhangye City as follows: firstly, fostering the ambience of the development of agricultural recycle economy; secondly, forming the incentive mechanism of development of agricultural recycle economy; thirdly, broadening the investment channel of development of agricultural recycle economy; fourthly, perfecting socialized service system of agricultural recycle economy.

A parameterized numerical model is constructed to compare platform options for collecting aerial imagery to support agriculture electronic information services in developing countries like India. A sensitivity analysis shows that when Unmanned Aerial Vehicles, UAVs, are limited in flight altitude by regulations, the velocity and altitude available to manned aircraft lead to a lower cost of operation at altitudes greater than 2000ft above ground level, AGL. If, however, the UAVs are allowed to fly higher, they become cost-competitive once again at approximately 1000ft AGL or higher. Examination of assumptions in the model highlights two areas for additional technology development: baseline-dependent feature-based image registration to enable wider area coverage, and reflectance reconstruction for ratio-based agriculture indices.
Full Text Available The primary objective of the study was an analysis of Polish agriculture development after 4 years of joining the European Union. The changes were associated with the strategy of the Common Agricultural Policy, which led to a reorientation in the sphere of agriculture production and also to adopting high standards resulting from cross-compliance requirements. Adoption of the sugar policy has led to an increase of cereal crops and plants associated with biofuels. In turn, the introduced milk quota contributed to the concentration and specialization of animal production. There was a positive development in commercial agricultural production, consisting in improving the quality and food safety.

Based on the current situation of ecological environment of agriculture in Tianjin City,we divide the ecological service function of urban modern agriculture in Tianjin City into seven types: air regulation,climate regulation,water conservation,soil formation and protection, waste disposal,biodiversity conservation,and ecological entertainment. According to the method for assessing the value of natural ecosystem, coupled with the ecological service value equivalency factor table of China’s ecosystem formulated by domestic scholars,we estimate the ecological value in Tianjin City. The results show that the actual ecological value of agriculture in Tianjin City was 30. 752 billion yuan in 2010,close to the agricultural economic value ( 31. 733 billion yuan) in 2010. Finally we put forth the following countermeasures for the ecological function development of urban modern agriculture in Tianjin City: strictly protecting arable land,and raising the standards of compensation for agricultural land requisition; actively and prudently developing facility agriculture,and preventing the blind scale expansion of facility agriculture to better give play to its ecological function; strengthening the construction of ecological agriculture,and promoting the market conversion of the ecological service value of agriculture; improving the environment,to form relatively complete agro-ecological system.
By selecting the data from 1989 to 2009 in China, we conduct regression analysis on the total output value of agriculture, the usage amount of chemical fertilizer, total power of agricultural machinery, effective irrigation area, and the damage area. The results show that the usage amount of chemical fertilizer and the damage area, the great obstacle to the construction of resource-saving and environment-friendly agriculture, have significant impact on the output value of agriculture; total power of agricultural machinery and effective irrigation area have insignificant impact on the output value of agriculture. Based on these, the suggestions for promoting the development of resource-saving and environment-friendly agriculture are put forward as follows: transform agricultural production mode, and optimize the industrial structure of agriculture; promote scientific use of chemical fertilizer, and promote the ability of agriculture to resist risks; promote the development of biogas in rural areas, and carry out the comprehensive use of biological material resources in rural areas.

Full Text Available The rapid evolution of civilisation within the last two hundred years has involved the replacement of extensive, pastoral livestock systems for intensive production methods. The dangers implicit in this rapid evolution are discussed by Forrester (1971,in the Meadows report (1972 and latterly the necessity for “sustainable development” was flagged by the Brudtland Report (1987. The last agrarian reform in Romania increased the weight of small farms and led to non sustainable agriculture. In such conditions we are obliged to follow a twin-track strategy: (1livestock systems with high productivity potentials; (2traditional pastoral systems and organic agriculture, on marginal lands, which allow the utilisation of extensive grazing lands, the conservation of environment, genetic resources, landscape, the minimisation of the use of non-renewable resources and the production of "natural foods".

The main agricultural areas in South Florida are located within the fertile land surrounding Lake Okeechobee. The Atlantic Watershed monthly rainfall anomalies showed a weak but statistically significant correlation to the Oceanic Nino Index (ONI). No other watershed s anomalies showed significant correlations with ONI or the Southern Oscillation Index (SOI). During La Nina months, less sea breeze days and more disturbed days were found to occur compared to El Nino and neutral months. The increase in disturbed days can likely by attributed to the synoptic pattern during La Nina, which is known to be favorable for tropical systems to follow paths that affect South Florida. Overall, neither sea breeze rainfall patterns nor total rainfall patterns in South Florida s main agricultural areas were found to be strongly influenced by the El Nino Southern Oscillation during our study time.

Taking Wangcang County of Sichuan Province as an example,this paper made comprehensive benefit analysis on models of circular agriculture in Wangcang County. Major models include " pig- biogas- fruit", " pig- biogas- vegetable",and " pig- biogas- tea". It made cost benefit analysis of economic,social and ecological benefits. Through benefit analysis charts,it obtained that the net present value of each household building biogas pool is 6029 yuan. In this way,it significantly improved ecological environment and social benefits,and the agricultural economic development model gradually changes to sustainable development model. However,there are still problems of insufficient government input and single model of agricultural circular economy. Therefore,government should increase input and develop diversified agricultural circular economical models in accordance with local situations,to realize sustainable agricultural development.

Statistics Norway produces the report 'Agriculture and Environment - State and Development' on annual commission from the Norwegian Agricultural Authority.The report contains statistical information on status and development of agrienvironmental issues in Norwegian agriculture. A wide range of data sources from Statistics Norway and other institutions serve as input to this information. The report is published in Norwegian and is available on the Internet: http://www.ssb.no/emner/10/04/ Land use and agricultural holdings In the period 1999-2011 the agricultural area in use was reduced by 3.9 per cent. Fully cultivated agricultural land decreased by 7.4 per cent, while there was a 29 per cent increase in infield pastures. In 2011 the agricultural area in use was estimated to about 1.0 million hectares. In 2011 there were 45 500 holdings with agricultural activity in Norway, 36 per cent lower than in 1999. Transfer of agricultural area to non-agriculture purposes In 2011, 660 hectares cultivated land and 390 hectares of cultivable land were transferred to non-agricultural use. Organic farming In 2011, organic farming covered about 5 per cent of the total agricultural area in use. The number of holdings with organic farming was 2 700, comprising 6 per cent of the total number of agricultural holdings in Norway. Plant protection: The Norwegian Food Safety Authorities has developed risk indicators for the use of pesticides in agriculture. The health risk decreased by 18 percentage points from 2005 to 2008, whereas the environmental risk decreased by 7 points in the same period. Sales of commercial fertiliser In 2011, the total amount of nutrients in commercial fertiliser was on the same level as in the 1960's. The sales of nitrogen were on the level as in the 1970's, while the sales of phosphorus were lower than in the 1950's.

Full Text Available The article discusses the current state and the main trends in the development of agriculture (on the example of agricultural enterprises in the Vologda Oblast. Nowadays there is a trend of decline in the production of basic agricultural products. The insufficient financing of agricultural enterprises is one of the key reasons for this situation. Internal and external sources of funding can be such tools. As world practice shows, the largest share in the funds, which are at the disposal of agricultural enterprises, accounts for direct budgetary financing. However, in the Russian Federation there is another trend: over the last decades there is noticeable reduction in direct state support of agricultural producers. In addition, in the framework of Russia’s accession to the WTO there will be further decline in such support and simultaneous transfer of financial burden onto agricultural enterprises. Therefore, the government faces an acute problem of planning and forecasting volumes of state support and earnings of agricultural enterprises. In this regard, this work makes a forecast calculation of the amount of public support and the revenue size of agricultural enterprises. To make forecasts the author uses methods of econometric modeling and forecasting (in particular, the method of correlation and regression analysis. The forecasts are presented in 3 scenarios: most realistic, optimistic and pessimistic. The article offers recommendations on determining the actual needs of regional agricultural enterprises in the amount of state support
Full Text Available This paper aims to analyze tariff protection policies in the agricultural sector of developing countries. The agricultural tariff structure in developing countries is characterized by: i high average tariffs, ii the existence of tariff escalation, iii dispersion of nominal tariffs across tariff lines, and iv a wide gap between average nominal tariffs and import-weighted average tariffs. Consequently, some features can be extracted that are consistent with the observed patterns of tariff protection in developing countries: i escalation of nominal tariff rates with the degree of processing, ii higher average tariffs in the agricultural sector compared to agriculture in developed countries, and iii higher non-agricultural than agricultural tariff protection. Here the Theory of Political Tariff Protection for Agricultural Sector in developing countries is described. This theory allows us to identify two sets of products. Agricultural products for which tariffs are higher than their political fitted values, therefore, tariff cuts should occur in a long period of time and for which tariffs are higher than their political fitted values therefore tariff reductions would not be politically costly.

Although George Herbert Mead is widely known for his social psychological work, his views on science education also represent a significant, yet sometimes overlooked contribution. In a speech delivered in March 1906 entitled "The Teaching of Science in College," Mead calls for cultural courses on the sciences, such as sociology of science or history of science courses, to increase the relevancy of natural and physical science courses for high school and university students. These views reflect Mead's perspective on a number of traditional dualisms, including objectivity versus subjectivity and the social sciences versus natural and physical sciences. Taking a sociohistorical outlook, I identify the context behind Mead's approach to science education, which includes three major influences: (1) German intellectual thought and the Methodenstreit debate, (2) pragmatism and Darwin's theory of evolution, and (3) social reform efforts in Chicago and the General Science Movement.

Also Slovene agriculture, its direction, intensity level, size and proprietal structure was subject to considerable changes as a result of inclusion of Slovenia in the EU and implementation of the Common Agricultural Policy. However it should be considered whether the direction of development of Slovene agriculture corresponds to protection and conservation of our major natural resources?
Full Text Available Zimbabwe is basically endowed in agricultural resources. As a result agricultural activities have a large bearing on developmental issues in the country. Employment is one such economic issue that hinges much on agricultural development. Over the past decade employment levels have reduced as a result of low investment in the country. Masvingo Province has not been spared. This scenario has seen many youths being out of employment as the sector employed less labour. The study found out that economic woes that Zimbabwe experienced over the past half decade have contributed significantly to youth unemployment in agriculture in Masvingo Province as a result of low investment in the sector. The study recommends that heavy investment be put in agriculture and agriculture related projects to enhance employment levels of the Zimbabwean youths in Masvingo province.

Based on the provincial units evaluation,this paper makes an assessment for sustainable developing capability of the integrated agricultural regionalization in China.At first ,an index system of agricultural sustainable development in China is built up,which includes 5 supporting subsystems of agricultural resources,agricultural develop-ment ,environment and ecosystem,rural society,sciences-esucation and management.We selected 95 factors on provin-cial level as basic indexes.Second,a relative assets/debt assessing method is used to gain relative net assets values (relative superiority) of every provincial unit,which are as supporting data for assessment.We also overlaid the Administra-tive Divisions Map of China and the Map of Integrated Agricultural Regionalization of China by Geography Information Sys-tem(GIS) to gain the area units of assessment.Third,according to the relative coherence principle of regionalization,we transform administration units to natural units through homogenizing all provincial relative net assets values in every agricultural assessing unit.After making order and grade,we complete the sustainable developing capability assessment to integrated agricultural regionalization in China.The assessing outcome shows that the total sustainable agricultural devdelop-ing capability of China is not high.Only about 1/3 in number or in area has reached the level of agricultural sustainable development.The relative net assets values exists a reducing trend from East China to West China.It needs a long period and great efforts to realize sustainable agricultural development over all China.Finally,there is a discussion to the study method.
Full Text Available Agriculture is usually developed as much and just society where there is a branch of the economy. Today, there are different directions from industry agriculture to many concepts based on ecological principles. Future of agriculture development in the XXI century will imply sustainable agriculture as the alternative to the industrial agriculture. Conventional agriculture as an intensive one has a duty to ensure maximum production in terms of quantity and quality with the low cost. For this purpose we have many cultural practices, sometimes in addition to the expected positive but sometimes with many unexpected long-term negative effects in agroecosystems. Organic agriculture is one of the most interesting current trends in agriculture completely based on strong ecological principles and the absence of application of agrochemicals (pesticides, fertilizers, hormones, GMO, etc. Organic agriculture is a holistic way of farming: besides production of goods of high quality (better flavor, high content dry matter, vitamins, antioxidants; conservation of the natural resources (soil, water and richness of biodiversity.
Full Text Available As an agricultural nation, the agricultural landscape is the basic appearance and existence in China, but the common existence often be neglected and contempted. As a new type of design and ideology, the development of urban agricultural landscape will greatly affect the texture and structure of the urban space. According to the urban agricultural production data and the socio-economic data of Weifang County, a set of evaluation index system that could analyze quantitatively the driving force of urban agricultural production changes and the internal drive mechanism was built. The original driving force indicators of economy, society, resources and environment from the time-series were chosen, and then 15 driving forces from the original driving forces by correlation analysis and principal component analysis were selected. The degree of influence was analyzed and the driving forces model by means of partial least squares(PLS was built. The results demonstrated that the factors greatly influenced the increase of urban agricultural output value in Weifang County were per capita net income of rural residents, agricultural machinery total power, effective irrigation area, centralized treatment rate of urban sewage, with the driving exponents 0.2509, 0.1019, 0.1655, 0.1332, respectively. The negative influence factor was the use amount of agricultural plastic film and the driving exponent was-0.2146. The research provides a reference for the development of urban agriculture, as well as a reference for the related study.

Full Text Available The article highlights the specifics of the intellectual heritage of the American philosopher and sociologist George Herbert Mead, reflected in the fragmentary character of texts written by him and the principal incompleteness of his sociological concept. The habitual label of "symbolic interactionism" does not adequately reflect the originality of the ideas of Mead. This term, invented by Herbert Blumer, in its original meaning was not directly related to the concept of George Herbert Mead. But later there was a substitution of concepts and Mead was referred to symbolic interactionists, what corresponds to the real situation only partially. To clarify this issue, the article describes the key ideas of the sociological concept of Mead regarding his critical position on the radical behaviorism of John Watson. The theoreticalmethodological position of Mead defined by him as social behaviorism is in contrary relations with radical behaviorism. The main areas of criticism can be described as follows: maximum focus on the behavior and ignoring the wider context of its implementation, failure of behaviorists to explain the thinking processes, a simplified model of human behavior in which the individual plays the role of a puppet reacting mechanically to external stimuli.

These were the turning points in the sustainable development of annual crop farming in Brazil. Today, society recognizes the role of these pioneers as key to achieving social, economic and environmental sustainability. ZT/CA reversed the historically accelerating degradation of soil organic matter and soil structure by abandoning conventional tillage, thus improving soil physical and chemical characteristics. This was achieved by promoting cover cropping and permanent soil cover with crop residues, crop rotations, and complementary, environmentally suitable soil management technologies.
Full Text Available This paper provides identification and assessment of barriers to the implementation of the instruments of the Common Agricultural Policy (CAP that support sustainable development of agriculture. This issue has been studied on the example of individual farms of south-eastern Poland, which benefited from programs to support sustainable agriculture in 2004-2013. The introduction of agriculture on the path of sustainable development depends on institutional factors (including political, which can induce farmers to take into account the environment and future generations in their microeconomic decisions. It has been shown that the most important barriers to the efficient and effective implementation of programs in support of sustainable agriculture are financial and information and education constraints.
Full Text Available Agriculture is a sector of primary importance in Romania, both through its contribution to the economy and the share of employment. Its continuous development and improvement and the countryside must be designed and analyzed under three main aspects, namely agriculture, food and environment. The current analysis takes into account the state of Romanian agriculture today, but also economic and human potential of rural areas in the main areas of development, and their evolution in 2008-2013. The rural space in Romania is characterized by poor economic diversification and a major dependence on agricultural activities, which results in obtaining low incomes for farmers. The rural labour force should be directed to other activities, particularly in services, based on a correct and permanent information, human resource awareness and training. The rural employment strategies include measures to improve the quality of human resources to facilitate access to non-agricultural employment in connection with labour market needs.
With a changing climate, drought has become more intensified, of which agriculture is the major affected sector. Satellite observations have proven great utilities for real-time drought monitoring as well as crop yield estimation, and many remotely sensed indicators have been developed for drought monitoring based on vegetation growth conditions, surface temperature and evapotranspiration information. However, those current drought indicators typically don't take into account the different responses of various input information and the drought impacts during the growing season, revealing some limitations for effective agricultural drought monitoring and impact analysis. Therefore, the goal of this research is to build a framework for the development of an impact-oriented and remote sensing based agricultural drought indicator. Firstly, the global agricultural drought risk was characterized to provide an overview of the agricultural drought prone areas in the world. Then, the responses of different remotely sensed indicators to drought and the impacts of drought on crop yield from the remote sensing perspective during the growing season were explored. Based on previous works on drought risk, drought indicator response and drought impact analysis, an impact-oriented drought indicator will be prototyped from the integration of the drought responses of different indicators and the drought impacts during the growing season. This research can inform an impact-oriented agricultural drought indicator, help prototype an impact-oriented agricultural drought monitoring system, and thus provide valuable inputs for effective agricultural management.

Full Text Available This paper purports to discuss how the multifunctionality of agriculture - which is a view of agriculture as an activity that is not only economic but also environmental, social and cultural - could be incorporated in public and private strategies in order to achieve a rural sustainable development and a bigger income to the farmer. Therefore, the research problem is how the integration of the concept would be a strategy to meet the needs of fibre, energy and food production while maintaining sustainability in agriculture. At first a bibliography research was carried out, approaching the concepts of multifuncionality of agriculture and positive externalities; subsequently an empirical research was done, through a case study whose aim was to replicate a method to access the multifuncionality of agriculture in the city of Cunha (SP. The multifunctional agriculture generates positive externalities but, generally, the farmer is not paid for the social benefits of its production. For that reason, metrics are needed to assess the impact generated by the multifunctional agriculture so the farmer gets paid for the social services that arises from its production. As soon as the farmer gets paid for the positive outcome he/she is generating, we will get an agricultural model that is more aligned to rural sustainable development.

Since 2011, the Group on Earth Observations Global Agricultural Monitoring (GEOGLAM) Initiative has been working to strengthen the international community's capacity to use Earth observation (EO) data to derive timely, accurate, and transparent information on agriculture, with the goals of reducing market volatility and promoting food security. GEOGLAM aims to develop capacity for EO-based agricultural monitoring at multiple scales, from national to regional to global. This is accomplished through training workshops, developing and transferring of best-practices, establishing networks of broad and sustainable institutional support, and designing or adapting tools and methodologies to fit localized contexts. Over the past four years, capacity development activities in the context of GEOGLAM have spanned all agriculture-containing continents, with much more work to be done, particularly in the domains of promoting access to large, computationally-costly datasets. This talk will detail GEOGLAM's experiences, challenges, and opportunities surrounding building international collaboration, ensuring institutional buy-in, and developing sustainable programs.

Agriculture in the Lower Benue River Basin faces several challenges which threaten the future of agricultural development. This study was an assessment of potential impacts of climate change on agricultural development in the Lower Benue River Basin. Through analysis of physical and socioeconomic parameters, the study adapted an impact assessment model to rank potential impacts on agricultural development in the study area. Rainfall intensity seemed to be increasing with a gradual reduction in the number of rainy days. The average discharge at Makurdi hydrological station was 3468.24 cubic metres per second (m(3) s(-1)), and the highest peak flow discharge was 16,400 m(3) s(-1). The daily maximum temperature and annual temperature averages for the study area are gradually rising leading to increased heat stress. Physical and chemical analyses showed that the soils are moderately fertile but require effective application of inorganic and organic fertilisers. The main occupational activities in the study area are agricultural based. The identified potential impacts of climate change on agriculture were categorised under atmospheric carbon dioxides and oxides, rainfall intensity, frequency of floods and droughts, temperature intensity and variation, heat stress, surface water trends, and soil quality and fertility. The identified potential impacts related to population dynamics on agriculture were categorised under population growth, rural-urban migration, household income and infectious diseases and HIV and AIDS. Community-level mitigation strategies were proffered. Policy makers are advised to promote irrigation farming, support farmers with farm inputs and credit facilities and establish active agricultural extension services to support the sustainable development of agriculture.
Full Text Available Market prices of agricultural land in the world have increased significantly in recent years. Important factors in regard to this trend are not only the fact that land is a basic, irreplaceable resource for the production of food and natural resources of each country, but also the fact that it is generally perceived as a favorable holder of capital, not succumbing to the effects of inflation. Market prices of agricultural land and the rent level in individual EU member countries are affected by historical development, the size structure of agricultural businesses, legislation, regulation of the land market, natural conditions and the intensity of agricultural production (e.g. the Netherlands. Market prices of agricultural land in the Czech Republic are monitored by the Czech Statistical Office (CSO, Institute for Agricultural Economics and Information (IAEI and Ministry of Agriculture (MoA, but output of the data base is not comparable within a time series 1993-2012, as institutions work with differing methodology. On the basis of the description of prices of agricultural land and regression analysis, the hypothesis that the market price of agricultural land for agricultural use in the Czech Republic is affected primarily by its quality was not confirmed. The official (administrative price is only an orientational and subsidiary tool for the determination of the market price. The development of the agricultural land market in the Czech Republic was affected by the privatization of land after 2000. According to an estimate (of the author, after the completion of privatization, and also in view of changes in tax policy, the prices of transacted land for agricultural use can decline within 3 years (2014 by up to 30%. It is probable that the demand will be focused on transactions with land for speculative and investment purposes, as, according to world trends, the average increase in value of investments in land in a time of economic crisis is

Mead is a traditional drink that contains 8%-18% (v/v) of ethanol, resulting from the alcoholic fermentation of diluted honey by yeasts. Mead fermentation is a time-consuming process and the quality of the final product is highly variable. Therefore, the present investigation had two main objectives: first, to determine the adequate inoculum size of two commercial wine-making strains of Saccharomyces cerevisiae for the optimisation of mead fermentation; and second, to determine if an increase in yeast pitching rates in batch fermentations altered the resulting aroma profiles. Minor differences were detected in the growth kinetics between the two strains at the lowest pitching rate. With increasing pitching rates net growth of the strain ICV D47 progressively decreased, whereas for the QA23 the increasing inoculum size had no influence on its net growth. The time required to reach the same stage of fermentation ranged from 24 to 96 h depending on the inoculum size. The final aroma composition was dependent on the yeast strain and inoculum size. Fourteen of the twenty-seven volatile compounds quantified could contribute to mead aroma and flavour because their concentrations rose above their respective thresholds. The formation of these compounds was particularly pronounced at low pitching rates, except in mead fermented by strain ICV D47, at 10(6) CFUs/mL. The esters isoamyl acetate, ethyl octanoate and ethyl hexanoate were the major powerful odourants found in the meads. The results obtained in this study demonstrate that yeast strain and inoculum size can favourably impact mead's flavour and aroma profiles.
By using conceptual model of BPEIR(Behavior-Pressure-Effect-Impact-Response) and Delphi method,we establish the evaluation index system of agricultural circular economy including four indices,namely index of socio-economic development,index of reducing input of resources,index of recycling of resources and index of safety of environment and resources.We conduct comprehensive evaluation on developmental level of agricultural circular economy from 1998 to 2007 in Hunan Province.The analysis results show that the agricultural circular economy of Hunan Province from 1998 to 2007,on the whole,has the tendency of development with annual growth rate of 1.89%.The annual decrease rate of recycling of resources and reducing input of resources from 1999 to 2003 is 25% and 11% respectively,which has become the main factor impeding development of agricultural circular economy.After the year 2003,it is mainly reducing input of resources.
Full Text Available In the present paper an attempt has been made to find out the spatial variation in the adaptation of improved agricultural practices to ascertain the level of agricultural development in Bulandshahr district of western Uttar Pradesh. The spatial variation of agricultural development is determined with the help of nine variables viz. net sown area, irrigated area, cropping intensity, crops productivity, area under HYV, agricultural labourers, role of banks and agricultural machinery. Beside this, the development of blocks are taken with their respective categories viz. high, medium and low on the basis of scores (like mean SD of these variables. These analyses have been carried out by transforming and combining the data related to nine variables, using ‘Z’ score to get the composite score. On the basis of Composite Score, developments of blocks have been again categorized in to three categories i.e. high, medium and low. Results of the aforesaid analysis shows that the modern technological inputs have reciprocal relationship with agricultural development in the study area.
Full Text Available Social ties play an important role in agricultural knowledge exchange, particularly in developing countries with high exposure to agriculture development interventions. Institutions often facilitate agricultural training projects, with a focus on agroecological practices, such as agroforestry and agrobiodiversity. The structural characteristics of social networks amongst land managers influences decision-making to adopt such adaptive agroecoloigcal practice; however, the extent of knowledge transfer beyond direct project participants is often unknown. Using a social network approach, we chart the structure of agrarian knowledge networks (n = 131 in six communities, which have been differentially exposed to agriculture development interventions in Ghana. Farmer network size, density and composition were distinctly variable; development project-affiliated farmers were embedded in larger networks, had non-affiliated farmers within their networks, were engaged in more diverse agricultural production and reported adopting and adapting agroecological practice more frequently. Such bridging ties that link across distinctive groups in a network can expose network members to new and innovative agroecological practices, such as increasing agrobiodiversity, thus, contributing to livelihood strategies that mitigate environmental and market risk. Furthermore, we show that these knowledge networks were crop-specific where network size varied given the type of crop produced. Such factors, which may influence the rate and extent of agroecological knowledge diffusion, are critical for the effectiveness of land management practices as well as the persistence of agriculture development interventions.

Full Text Available Main directions of development of small and medium-sized enterprises in Ukrainian agriculture are examined. It is determined that entrepreneurship in agrarian sector is a driving force behind the development of agriculture, as these activities contributes to the production of quality agricultural products that satisfies the needs of society, food security, independence and improves the living standards of rural population. Potential customers of small parties of harvest in Ukrainian grain market are analyzed. The ways of mutually beneficial cooperation between Ukrainian farmers and entrepreneurs are proved. The study of foreign experience has proven that strengthening the competitiveness of Ukrainian agricultural products in the context of globalization is possible on the basis of mutually beneficial cooperation of Ukrainian farmers and entrepreneurs, where recent purchase of output at market prices for the purpose of resale or creation of agricultural cooperatives, such form of economy in agrarian relations that combines a balanced economic, social and environmental components. In particular in paper is shown that sustainable economic management provide only forms of economy that take into account the socioeconomic and geophysical specifics of agriculture, particularities of agricultural labor and methods of management. The most common among these forms are farmers.

Agriculture has been central to accounts of Thailand's modernisation and the rise of the national development project between the 1940s and the 1970s. However, the role of agriculture in the waning of national development is rarely explored critically in the Thai context. This paper focuses on agriculture and the role of the state in the shift from national development to globalisation. The first part of the paper examines the beginnings of Thailand's modern agricultural sector, before turning to the state-sponsored diversification of agriculture in the 1950s. The paper locates shifting state responses to agriculture in the late 1950s and 1960s in the context of specific political and historical social forces, before exploring the emergence of agri-food exports in the 1970s and the rise of agribusiness in the 1980s and 1990s. The paper concludes by commenting on the significance of the Thai state's role in the national development project and the globalisation project.

Mead fermentation is a time-consuming process, often taking several months to complete. Despite of the use of starter cultures several problems still persist such as lack of uniformity of the final products, slow or premature fermentation arrest and the production of off-flavors by yeast. Thus the aim of this study was to optimize mead production through the use of an appropriate honey-must formulation to improve yeast performance alcoholic fermentation and thereby obtain a high quality product. Honey-must was centrifuged to reduce insoluble solids, pasteurized at 65°C for 10 min, and then subjected to different conditions: nitrogen supplementation and addition of organic acids. Although the addition of diammonium phosphate (DAP) reduced fermentation length, it did not guarantee the completeness of the fermentation process, suggesting that other factors could account for the reduced yeast activity in honey-must fermentations. Sixteen yeast-derived aroma compounds which contribute to the sensorial quality of mead were identified and quantified. Global analysis of aromatic profiles revealed that the total concentration of aroma compounds in meads was higher in those fermentations where DAP was added. A positive correlation between nitrogen availability and the levels of ethyl and acetate esters, associated to the fruity character of fermented beverages, was observed whereas the presence of potassium tartrate and malic acid decreased, in general, their concentration. This study provides very useful information that can be used for improving mead quality.

Full Text Available This paper pays attention to global issues related to the growth of population and food production: reduced growth rate of agricultural production, reduction of resource potential of agriculture and others. Critical factors and trends of structural changes in agriculture are identified. Results of comparative analysis of the development of farms in European countries and Russia are presented. Studies have shown that at the end of the last century there have been the following trends in the global agriculture: there has been a trend of farm consolidation in size, new controls and control of production are were introduced as well as more stringent quality standards of ecology were launched, which, in turn, require introduction of new technics and technologies; the processes of plants and animals development become more controllable and manageable. Conseptual foresights of pricing in the food market are given. Priority areas of agricultural policy aimed at creating conditions for sustainable rural development and accelerated growth in agricultural production by improving its competitiveness are identified
The necessity of transition of agriculture to sustainability is complicated by the necessity to increase production of local environmentally safe food, unemployment indigenous growth of living standards of the peasant community, stable and balanced nature management. Due to the difficult economic conditions of natural and agricultural development for the Komi Republic principle of food self-sufficiency is unacceptable, but the production of basic food products, for which favorable there are conditions, is objective necessity in the short term. Priority directions of development of the agricultural and fisheries sectors: the production of socially significant food products - potatoes, vegetables of the local range, milk, fresh meat, eggs, dietary, preservation and development of traditional industries, and collecting wild mushrooms and berries and its processing. Off forecast in the northern agricultural areas three scenarios selected: a base (slow), optimistic and pessimistic. For all versions of the forecast to be considered systemic crisis of the agricultural sector of the North is ongoing. Functioning of on sector under a particular scenario will depend on the factors and conditions that affect the stability of the agricultural enterprises and farms. At the base, especially under unfavorable conditions, negative external factors and conditions will prevail. The baseline scenario of recent years assumes the maintenance of the rate of change indicators of agriculture, of the levels of state industry conditions of interbranch exchange in agriculture, of access to economic entities in the financial markets, of the pricing and taxation policies, of relatively low investment opportunities to upgrade production capacity. In this embodiment the growth of agricultural production and its reduction will occur in suburban (peripheral areas). The optimistic scenario will be characterized by protectionist policies of the state, increase investment to improve soil fertility

The agricultural and industrial development of small cities is the primary environmental management strategy employed to make full use of extra labor in the rural areas of China. The ecological and economic consequences of this development strategy will affect over 100 million people and change the organization of the Chinese landscape. In this study, we examined the agricultural development of Shunde, a small city in Guangdong Province, over the period 1978 until 2000. Our analysis of the ecological and economic dynamics of the agricultural system revealed the dominant role of labor in the intensification of agricultural production, even though the use of fuels, fertilizers and machines also increased during this time. The Shunde agricultural system was examined from both biophysical or donor-based and human utility or receiver-based perspectives, using emergy and economic methods, respectively. After 22 years of urbanization, the Shunde agricultural system was still able to fill 96% of the local demand for agricultural products using only 6% of its total yield compared to using 14% of the total yield in 1978. Aquaculture developed quickly during the study period as grain production decreased. In 2000, the production of fish, pork, and vegetables accounted for 92% of the total emergy output of the system; however, the emergy buying power of the money received in exchange was lower than the emergy contained in the products exported. The excess emergy exported is the basis for a high quality diet delivered to city dwellers at a relatively low price. In the 1980s, the productivity of both land and labor increased; but after 1992 the productivity of labor decreased, causing the efficiency of the whole agricultural system to decrease. We recommend that processing plants be established for the main agricultural products of Shunde to decrease the emergy loss in trading and to increase employment. The effect of including monetized ecosystem services in the balance between
Full Text Available In this paper, the development of biodegradable containers for crops that could be transplanted directly and act as fertilizers is proposed. Bovine gelatin was chosen as the base material, which was processed in a mini-injector mixer with a concentrated urea solution acted as a plasticizer. Rheological and tensile tests were performed in order to evaluate the injection of gelatin based formulations and mechanical properties related to the proposed application. Taking into account that biodegradable materials have a low water resistance, the increment of container stability was proposed using a surface coating. In addition, the influence of moisture content, the soluble matter and swelling were studied and analyzed. It was observed that coated samples were significantly more stable than the control ones, which guarantees the feasibility of the selected system and its potential development of biodegradable containers.

Full Text Available A rainfall simulation model based on a first-order Markov chain has been developed to simulate the annual variation in rainfall amount that is observed in Bangladesh. The model has been tested in the Barind Tract of Bangladesh. Few significant differences were found between the actual and simulated seasonal, annual and average monthly. The distribution of number of success is asymptotic normal distribution. When actual and simulated daily rainfall data were used to drive a crop simulation model, there was no significant difference of rice yield response. The results suggest that the rainfall simulation model perform adequately for many applications.

This paper presents a decision support system (DSS) for sustainable development and environmental protection of agricultural regions developed in the framework of the Interreg-Archimed project entitled WaterMap (development and utilization of vulnerability maps for the monitoring and management of groundwater resources in the ARCHIMED areas). Its aim is to optimize the production plan of an agricultural region taking in account the available resources, the environmental parameters, and the vulnerability map of the region. The DSS is based on an optimization multicriteria model. The spatial integration of vulnerability maps in the DSS enables regional authorities to design policies for optimal agricultural development and groundwater protection from the agricultural land uses. The DSS can further be used to simulate different scenarios and policies by the local stakeholders due to changes on different social, economic, and environmental parameters. In this way, they can achieve alternative production plans and agricultural land uses as well as to estimate economic, social, and environmental impacts of different policies. The DSS is computerized and supported by a set of relational databases. The corresponding software has been developed in a Microsoft Windows XP platform, using Microsoft Visual Basic, Microsoft Access, and the LINDO library. For demonstration reasons, the paper includes an application of the DSS in a region of Northern Greece.

We propose the use of "Optical Farming," which is the leading application of all types of optical technologies, in agriculture and agriculture-related industries. This paper focuses on the optical sensing instruments named "Agriserver," "Agrigadget" and "LIFS Monitor" developed in our laboratory. They are considered major factors in utilizing Optical Farming. Agriserver is a sensor network system that uses the Internet to collect information on agricultural products growing in fields. Agrigadget contains several optical devices, such as a smartphone-based spectroscopic device and a hand framing camera. LIFS Monitor is an advanced monitoring instrument that makes it possible to obtain physiological information of living plants. They are strongly associated with information communication technology. Their field and data usage performance in agricultural industries are reported.
In recent years, a global increase in demand for agricultural commodities and land has contributed to increasing agricultural prices. This trend can be expected to continue in the future, and may result in significantly higher land rents. This paper investigates the potential distributional effects...... of increasing land rents in land-abundant developing countries from a theoretical viewpoint, and provides historical case examples to support the theoretical propositions. It is proposed that the specific characteristics of a rent-generating natural resource have implications for the concentration of economic...... and political power and hence the distribution of rents. Specifically, when it comes to agricultural land, the characteristics of land imply that the organizational capacity of farmers is a crucial determinant of the distribution of agricultural rents. The historical case examples indicate that the extent...

Full Text Available Organic farming uses sustainable production systems, diversified and balanced to prevent environmental and harvest pollution. In this paper I wish to highlight the opportunities arising from the practice of sustainable agriculture and the efficient management of natural resources in Romania. Sustainable rural development can be achieved with the transition from subsistence agriculture to organic agriculture by building and strengthening competitive small and medium enterprises in rural areas. For this we analyzed empirical data provided by the Ministry of Agriculture, Forests and Rural Developmen and the National Institute of Statistics.The analyzed period covers the years 2006-2011. The organic food market in Romania is contoured by statistical methods and the opportunities and limitations incurred by those who choose this form of exploitation.
Full Text Available Basically, climate change refers to any change in climate overtime, generally caused by natural variability and/or human activities. It has great devastating impact, particularly on agriculture and by extrapolation on farmers and the national economy. The frontline agricultural extension workers are expected to be among the principal stakeholders to teach farmers how to cope with climate change. Consequently, there is a need to develop appropriate teaching package for the training of the frontline agricultural extension workers, based on the myriad of adaptation strategies and practices available in the literature. This paper synthesizes the rationale for capacity building in climate change and the adaptation or coping strategies. The modules (train-the-trainer for teaching agricultural extension workers and farmers are documented in the paper.

Modernization of agricultural systems to increase output causes changes to the nutritional content of food entire populations consume. Human nutritional needs differ from their "food", thus producing healthy agricultural products is not equivalent to providing agricultural products that are healthy for humans. Inclusion of the food production system as a factor in the increase of neuropsychiatric disorders and other chronic diseases helps explain negative trends in modern chronic diseases that remain unchecked despite stunning advances in modern medicine. Diseases in which our own technology plays a significant role include obesity and resulting disorders, such as diabetes, heart disease, hypertension, stroke and arthritis. Modernization's lure leads to importation of modern agricultural practices into a nutritionally vulnerable, malnourished and sometimes starving developing world. Wealthier nations hedge their food portfolio by having access to a wider variety of foods. The developing world's reliance on staple foods means even a minor widespread nutritional modification of one key food can have profound effects. New agricultural techniques may improve or exacerbate neuropsychiatric disorders through nutritional modification in regions where populations walk a nutritional tightrope with little margin for error. In most of the developing world western psychiatric interventions have failed to make inroads. People's consumption of fish has a demonstrated beneficial effect on their mental health and the omega-3 fatty acid content is a significant factor. Epidemiological, biological and agricultural studies implicate a lack of dietary omega-3s as a factor in certain mental disorders. Replenishing omega-3s has improved mental illnesses in controlled clinical trials. This article's detailed tilapia fish-farming model demonstrates how aquaculture/agriculture techniques can function as a public health intervention by increasing dietary omega-3s through creation of

Latest FAO figures indicate that an estimated 925 million people are undernourished in 2010, representing almost 16% of the population in developing countries. Looking to the future, there are also major challenges ahead from the rapidly changing socio-economic environment (increasing world population and urbanisation, and dietary changes) and climate change. Promoting agriculture in developing countries is the key to achieving food security, and it is essential to act in four ways: to increase investment in agriculture, broaden access to food, improve governance of global trade, and increase productivity while conserving natural resources. To enable the fourth action, the suite of technological options for farmers should be as broad as possible, including agricultural biotechnologies. Agricultural biotechnologies represent a broad range of technologies used in food and agriculture for the genetic improvement of plant varieties and animal populations, characterisation and conservation of genetic resources, diagnosis of plant or animal diseases and other purposes. Discussions about agricultural biotechnology have been dominated by the continuing controversy surrounding genetic modification and its resulting products, genetically modified organisms (GMOs). The polarised debate has led to non-GMO biotechnologies being overshadowed, often hindering their development and application. Extensive documentation from the FAO international technical conference on Agricultural Biotechnologies in Developing Countries (ABDC-10), that took place in Guadalajara, Mexico, on 1-4 March 2010, gave a very good overview of the many ways that different agricultural biotechnologies are being used to increase productivity and conserve natural resources in the crop, livestock, fishery, forestry and agro-industry sectors in developing countries. The conference brought together about 300 policy-makers, scientists and representatives of intergovernmental and international non

Full Text Available This study aims to highlight the status of agricultural R&D in South Asia and contends that creating an effective agricultural research and innovation systems is a vital element to ensure food security in this region. South Asia is home to around one-fourth of mankind and houses the largest proportion of undernourished people in the world. Despite a period of marked economic growth averaging 6% a year over the past two decades, it remains the world's second poorest region contributing a mere 2.2% in global annual GDP. Agriculture is the mainstay of South Asian economy employing around 60% of the total workforce and generating around 20% of total GDP. South Asia has the recognition of being the second most food-insecure region next only to sub-Saharan Africa. Though there is growing evidence that technological innovation has a key role to play in increasing agricultural production and strengthening food security, agricultural research and development (R&D sector has failed to garner sufficient attention till now. This study also depicts the current situation of food security in South Asia and illustrates how agricultural education and innovation hold the master key to solve the food security issues for the world's most densely populated region.

ée centrale de certains de ses écrits. Il faut en outre ajouter que l’on a opté, dans cette synthèse, pour présenter l’évolution de sa pensée pédagogique sur la base de moments singuliers et exceptionnels, montrant ainsi les différentes continuités et discontinuités de sa pensée.The present article considers the work of the anthropologist Margaret Mead from an educational perspective. Thus, it offers an interpretation of her ideas on education through reference to the studies, comments and opinions regarding school systems, educational relationships and teaching/learning processes that appear repeatedly throughout her work. After all, and as the author herself pointed out, the study of education is implicitly required by every anthropological study, and this notion led her to include educational variables in most of her research; indeed, some of her writings take this aspect as their focus. The present review opts to present the development of her educational ideas according to key and charismatic features, thus revealing the various continuities and discontinuities in her thinking.En el presente artículo se ensaya una aproximación a la obra de la antropóloga Margaret Mead en clave pedagógica. Siendo así que se muestra una interpretación sobre sus pensamientos alrededor de la educación a partir de los estudios, comentarios y opiniones sobre los sistemas educativos, relaciones educativas y procesos de enseñanza aprendizaje que se explicitan, reiteradamente, a lo largo de su obra. A fin de cuentas, y como la propia autora indicaba, estudiar la educación era implícitamente necesario a todo estudio antropológico.

There is great potential for agriculture in saline-alkali soil area in Songnen Plain, Northeast China. Butthe sustainable crop production in this area has been restricted by a few of main factors, such as less precipitation, higherevaporation and frequent drought, high salinity and alkalinity, high exchangeable sodium content and poor infiltration ofthe soil, and insufficiency and low availability in nutrition. It is also considered that there are a few of favorable condi-tions for agricultural development in this region, such as sufficient light and heat resources, rich ground water resources,plenty of manure produced by livestock, and so on. At the same time, scientific management and measurements havebeen employed; rational irrigation and drainage system has been established; reclamation, amendment and fertilization ofsoil, and suitable strategies of cropping practices have been made for the sustainable development of agriculture. Greatprogress has been made during 1996- 2000.

By 2050, when cleanup of the Hanford Site is expected to be completed, large worldwide demands to increase the global production of animal and fish protein, food, and fiber are anticipated, despite advancements in crop breeding, genetic engineering, and other technologies. The most likely large areas for expanded irrigation in the Pacific Northwest are the undeveloped East High areas of the Columbia Basin Project and non-restricted areas within the Hanford Site in south-central Washington State. The area known as the Hanford Site has all the components that favor successful irrigated farming. Constraints to agricultural development of the Hanford Site are political and social, not economic or technical. Obtaining adequate water rights for any irrigated development will be a major issue. Numerous anticipated future advances in irrigation and resource conservation techniques such as precision agriculture techniques, improved irrigation systems, and irrigation system controls will greatly minimize the negative environmental impacts of agricultural activities.
Full Text Available The study examines the kind of actors and resources that empower small-scale farmers to promote sustainable agriculture. It also analyzes the reasons given by farmers who changed their farming methods. In 2004, the Department of Agriculture launched a project for the Promoting Organic Farming and Marketing in Lao PDR (PROFIL. PROFIL tried to develop market opportunities for Lao’s organic products and supported the local organic farmers. I conducted field researches at Nonte village in Vientiane Capital twice in 2008. The researches indicated that “Clean Agriculture” is one of the new challenges for farmers. Thus, this research focuses on the observation of how local organic farmers adapt to a new method and cope with problems. Information as knowledge from community groups and external actors such as local institutions and experts might help villagers to have choices in terms of farming methods, which gave them positive choices in terms of health and an agricultural environment. Since the government has the recognition of comparative advantages of clean agriculture, farmers may have the opportunity to gain a large market of organic farm products if they can develop distribution channels. This study encourages the positive contributions of challenges of sustainable agriculture in Lao PDR.

To increase the awareness of society to the challenges of global food security, we developed five contrasting global and European scenarios for 2050 and used these to identify important issues for future agricultural research. Using a scenario development method known as morphological analysis, scenarios were constructed that took economic, political, technical, and environmental factors into account. With the scenarios as a starting point future challenges were discussed and research issues and questions were identified in an interactive process with stakeholders and researchers. Based on the outcome of this process, six socioeconomic and biophysical overarching challenges for future agricultural were formulated and related research issues identified. The outcome was compared with research priorities generated in five other research programs. In comparison, our research questions focus more on societal values and the role of consumers in influencing agricultural production, as well as on policy formulation and resolving conflicting goals, areas that are presently under-represented in agricultural research. The partly new and more interdisciplinary research priorities identified in Future Agriculture compared to other programs analyzed are likely a result of the methodological approach used, combining scenarios and interaction between stakeholders and researchers.
Full Text Available The non-agricultural economy (small and medium-sized enterprises in industry, services, rural tourism has a low share in Romania's rural area. To start a business in the countryside can be both an advantage and a risk. The investments in the non-agricultural and food economy, while contributing to gross value added increase through the processing of agricultural and non-agricultural raw products from local resources, have another great advantage, by creating new jobs and by using and maintaining the local (rural labour, revitalization of rural localities, mainly those in the less-favoured and remote rural areas. The paper presents aspects of the management of small and medium enterprises in agriculture and services, in order to create a concrete analysis framework for sustainable development in rural areas. The socioeconomic analysis based on current data and future forecasts is the basis in drawing conclusions on the possibilities of encouraging a sustainable entrepreneurship in the less-developed regions and also for the economic revitalization.

In Botswana, approximately 40% of the population live in rural areas and derive most of their livelihood from agriculture by keeping livestock and practising arable farming. Due to the nature of their farming practises livestock and crops are exposed to diseases and environmental stresses. These challenges offer opportunities for application of biotechnology to develop adaptable materials to the country's environment. On the other hand, the perceived risk of genetically modified organisms (GMOs) has dimmed the promise of the technology for its application in agriculture. This calls for a holistic approach to the application of biotechnology to address issues of biosafety of GMOs. We have therefore assessed the potentials, challenges and opportunities to apply biotechnology with specific emphasis on agriculture, taking cognisance of requirement for its research, development and application in research and teaching institutions. In order to achieve this, resource availability, infrastructure, human and laboratory requirements were analyzed. The analysis revealed that the country has the capacity to carry out research in biotechnology in the development and production of genetically modified crops for food and fodder crops. These will include gene discovery, genetic transformation and development of systems to comply with the world regulatory framework on biosafety. In view of the challenges facing the country in agriculture, first generation biotech crops could be released for production. Novel GM products for development may include disease diagnosis kits, animal disease vaccines, and nutrient use efficiency, drought, and pest and disease resistant food and fodder crops.

Full Text Available Domestic and foreign experience of operation of the segment of "small" rural economy shows that its capabilities are still being used not completely out of the difficulties and risks of development. The main reason for the slow dynamics of the modern development of subjects of small farming (SAF, according to the authors, is the inaccessibility of the credit market in this sphere since the key rate of the Central Bank at 10.5%, which is too high and, therefore, significantly reduces the efficiency of the investments in this risky industrial sector. In addition, the most narrow «neck bottle» is remaining a unit of realization of products of small businesses. The authors propose a refined definition of "small agricultural businesses" that differs from the previous definitions by its conciseness and by including small enterprises of not only 1-st production, but also the 2-nd processing of agricultural sector. The study revealed that the most distinctive features of small agricultural forms are: high autonomy, independence, and self-protection from adverse environmental factors. The authors propose to adjust the long-term regional development program, and suggest the method of determining the capacity of the market for products of small agricultural farms with possibilities of a differentiated accounting of consumers by their income, residency, and consumption of domestic and other animals. They believe that the problem of affordability of lending and perfecting of system of marketing of small agricultural farming today is largely able to solve with the multi-level agricultural credit and sales-living cooperatives. The authors believe that the government should create a high-in-demand SAF productive assets and then transfer them to the operational management of cooperatives, with subsequent transformation of them into equity of the small participants of cooperatives

Full Text Available In the village, the agricultural development is not certainly oriented to the economic aspect. The social intervention is very important and very helpful for the citizens and the development of the agricultural itself. The purpose of this research is to analyze the social existence, the social influence, and also the systematic strategy that can strengthen the society in developing the agriculture. The method used in this research is the qualitative analysis with phenomenology approach. The qualitative analysis is conducted by the direct observation in the field and in-depth interviews with the respondents that are selected by the purposive sampling. The result shows that a society has formed the farmer organization to have mutual coordination among the members. However, there are some problems that occur on this organization. The values and norms begin to fade and have become the major problem. Another problem is the sense of trust among the citizens and the unoptimal social network utilization. The conclusion is, the Analytic Network Process (ANP shows that to make a progress of agricultural development, they need to strengthen the social relationship among the citizens to face all the problems that may occur.

Full Text Available The article analyzes the development of agriculture and trade relations in the Caucasus in the early 20th century. This article utilizes the records of Georgian national archives, pre-revolutionary periodicals and monographic literature published in pre-revolutionary, soviet and Russian contemporary periods. The authors used the research methods such as principles of objectivity, historicism, systematic, comprehensive accounting of the economic indicators of agriculture development and trade in the Caucasus and the maximum possible neutrality of the researcher to interpret factual material. The authors come to the conclusion that the development of agriculture in the Caucasus after the revolutionary upheavals of 1905-1907 years in the subsequent period before the First World War entered into the stage of recovery. The reasons of this phenomenon became the discovery of significant quantities of oil, cement, manganese and other fields. The objects of the industry demanded also the additional food supply, this enabled the agriculture in the Caucasus to develop actively.

Full Text Available This article addresses the management of agricultural indigenous knowledge (IK in developing countries, with a specific focus on Tanzania. It provides background details on IK and its importance for agricultural development. It introduces various knowledge management (KM concepts and discusses their application in managing IK in the developing world by placing Nonaka’s knowledge creation theory (Nonaka 1991; Nonaka & Takeuchi 1995; Nonaka, Toyama & Konno 2000 in the context of the local communities. Data from focus groups were used to triangulate with data from interviews in order to validate, confirm and corroborate quantitative results with qualitative findings. The study findings showed that knowledge creation theory can be used to manage IK in the local communities, however, adequate and appropriate resources need to be allocated for capturing and preserving IK before it disappears altogether. For sustainable agricultural development, the communities have to be placed within a knowledge-creating setting that continuously creates, distributes and shares knowledge within and beyond the communities’ boundaries and integrates it with new agricultural technologies, innovations and knowledge.

Full Text Available Snow and ice removal on highways and public streets is critical for safe operation of the road transportation infrastructure. The issues to be addressed in selecting suitable deicing and anti-icing materials include cost, effectiveness, and damage to the pavement, vehicles and the environment. Considerable research has been carried out in recent years to develop alternative deicers with better performance and cost effectiveness. Among the developed deicer materials are agricultural based deicers that are considered to be sustainable and environmentally-beneficial materials. Iowa is one of the States that is rich in agricultural renewable resources, some of which are being processed for applications such as fuel. Any industrial process, including that of converting corn to ethanol or soy to bio-diesel, is likely to have a number of by-products generated. Rather than face disposal issues for these by-products, it would be desirable to find those that, with a minimum of additional processing, can be used as a deicing compound, either alone, or in combination with products currently in use. Currently, a number of agricultural based deicer materials have been developed or are still under development. However, little information is known about the actual manufacturing/refining process since most of the developed materials are all proprietary products (patented or commercial. Furthermore, no standard test specifying agricultural-based deicer is available. The study described in this paper focuses on the development of an improved agricultural based deicing product. The objective of this study was to evaluate deicer materials including traditional and alternative deicer materials on road skid resistance which is critical for safe operation of the road transportation infrastructure.

Cuckoo search algorithm is a promising metaheuristic population based method. It has been applied to solve many real life problems. In this paper, we propose a new cuckoo search algorithm by combining the cuckoo search algorithm with the Nelder-Mead method in order to solve the integer and minimax optimization problems. We call the proposed algorithm by hybrid cuckoo search and Nelder-Mead method (HCSNM). HCSNM starts the search by applying the standard cuckoo search for number of iterations then the best obtained solution is passing to the Nelder-Mead algorithm as an intensification process in order to accelerate the search and overcome the slow convergence of the standard cuckoo search algorithm. The proposed algorithm is balancing between the global exploration of the Cuckoo search algorithm and the deep exploitation of the Nelder-Mead method. We test HCSNM algorithm on seven integer programming problems and ten minimax problems and compare against eight algorithms for solving integer programming problems and seven algorithms for solving minimax problems. The experiments results show the efficiency of the proposed algorithm and its ability to solve integer and minimax optimization problems in reasonable time.

En este artículo pretendo aportar líneas conceptuales para resignificar la socialización como categoría psicosocial, desde una perspectiva productiva para situar la comprensión de los procesos de subjetivación. Revisaré ciertos reduccionismos y linealidad explicativa en algunos abordajes de la socialización y argumentaré que la intersubjetividad es un nivel fértil para desarrollar categorías de comprensión que sean inclusivas de distintas dimensiones. En tal sentido, recupero categorías de la Psicología Social de George Mead ya que su trabajo es basal en cuanto a proponer una ontología de la intersubjetividad. Hay dos ejes que intento articular a lo largo del análisis de las categorías de Mead: i. el proceso simbólico en el que ancla la constitución de la persona, a través de los intercambios comunicativos en la acción intersubjetiva. ii. La pluralidad de perspectivas y la diversificación de expectativas de comportamiento que operan como referencia de las acciones, lo que, en mi interpretación, abre a una conceptualización de la socialización como un proceso conflictivo de diferenciación social.In this article I pretend to provide conceptual lines to resignify socialization as a psychosocial category, from a productive perspective in order to situate the comprehension of subjectivation processes.

The original technique of modeling with use of the modernized method of structural and parametrical identification of simulation model is offered. The block diagram of model is represented, the inclusion into its structure of the corresponding components is substantiated: expenses of appliances and work, agroclimatic conditions, indicators of soil fertility, structure of the ground area and the use of processed lands. Coefficients of the importance of the separate parameters influencing criterion function of regional systems of agriculture are revealed. Areas with various economic efficiencies of arable grounds are shown and the factors determining these distinctions are opened. A model of mathematical simulation is developed, allowing to estimate the degree of influence of territorial structure of agriculture and socio-economic factors on the efficiency of regional systems of agriculture and to define various possible scenarios of their sustainable development on the basis of the chosen criterion of stability — of economic efficiency.

Mechanisation of large-scale agricultural fields often requires the application of modern technologies such as mechanical power, automation, control and robotics. These technologies are generally associated with relatively well developed economies. The application of these technologies in some developing countries in Africa and Asia is limited by factors such as technology compatibility with the environment, availability of resources to facilitate the technology adoption, cost of technology purchase, government policies, adequacy of technology and appropriateness in addressing the needs of the population. As a result, many of the available resources have been used inadequately by farmers, who continue to rely mostly on conventional means of agricultural production, using traditional tools and equipment in most cases. This has led to low productivity and high cost of production among others. Therefore this paper attempts to evaluate the application of present day technology and its limitations to the advancement of large-scale mechanisation in developing countries of Africa and Asia. Particular emphasis is given to a general understanding of the various levels of mechanisation, present day technology, its management and application to large-scale agricultural fields. This review also focuses on/gives emphasis to future outlook that will enable a gradual, evolutionary and sustainable technological change. The study concludes that large-scale-agricultural farm mechanisation for sustainable food production in Africa and Asia must be anchored on a coherent strategy based on the actual needs and priorities of the large-scale farmers. © 2016 Society of Chemical Industry.

As part of a regional seismic hazard study for Reclamation dams on the northern lower Colorado River, the age and distribution of known and suspected late Quaternary faults were investigated and historic seismicity was analyzed for the western Lake Mead area. Late Quaternary faults in the area consist of the Mead Slope, Black Hills, Frenchman Mountain, and California Wash faults. Geologic mapping and scarp profiles indicate that of these late Quaternary faults, the Black Hills fault displays evidence for the youngest (probably mid-Holocene) surface faulting. No information about the ages of older events was obtained for any of the faults; however, the ages of the most recent surface-rupturing events for individual faults suggest recurrence intervals of tens of thousands of years for specific faults and regional recurrence rates of several thousand years for M[sub 3] [>=] 6 1/2 events. Since 1936 when Hoover Dam was completed and the initial filling of Lake Mead began, the Boulder Basin area, the largest and deepest part of Lake Mead, has experienced abundant seismic activity that includes some of the largest historic earthquakes in southern Nevada (at least 21 M 4 events and one M 5). Based on earthquake locations from early networks (1937--1950) and those from temporary networks operating in 1975--1976 and 1988, earthquakes are clearly associated with the northeast-striking Mead Slope and Black Hills faults; one of the few associations of seismicity with late Quaternary faults in the Basin and Range. However, earthquakes also appear to be associated with the Fortification fault, a north-striking fault with no evidence of Quaternary surface faulting. Focal mechanisms for some of the 1975--1976 and 1988 events (all events M [<=] 3) suggest active strike-slip/oblique-slip motion on north-striking faults and normal/oblique-slip motion on northeast-striking structures.

While much has been published on the advantages of organic agriculture, less has addressed its potentials and challenges to fight undernourishment in developing countries. This article aims at reviewing the main potentials and challenges of this approach when dealing with "undernourishment" as a multifaceted concept in developing countries. Accordingly, 2 main issues of the concept which are "food security" and "food safety" are discussed in the context of both developed and developing countries to understand their different food policies' priorities. Next, the main potentials, challenges and tradeoffs of the organic approach are analyzed to understand whether the approach is capable to provide a secure or a safe food-production system which can meet the food policy priorities in developing countries. With respect to food security, the article concludes that conventional and biotechnological approaches still produce higher yields than organic agriculture. However, considering the many advantages of organic agriculture, it can in a long run, be more conducive than now to meet food security. Thus, conventional approach is still needed to feed the hungers in developing countries [corrected]. Accordingly, the article emphasizes on the importance of providing farmers in developing countries with the possibility of implementing different approaches. Therefore, policy makers should be aware of a realistic and gradual transition from the other approaches to the organic that should be projected only in "long run," and after conducting a series of risk assessment studies on the bases of both "crop-case" and "region-case."
The plant protection by pesticides is increasing in Poland and the established trend rate took into account years 2005-2011. In the period 2002-2004 statistics did not present the full range of crop protection measures authorized for sale and consumption. In contrast the consumption of qualified seeds of basic grains and seed potatoes considerably decreased in Polish agriculture. Only for triticale it was noticed that the trend rate of qualified seeds was increasing. So the farmers should be more widely informed about the advantages of the exchange of seed grain for qualified grains. It will facilitate the quicker implementation of variety progress to agricultural production and adverse changes slowdown agricultural production.

Sowing of seedlings is one of the most critical processes on the establishment of a crop, since the future development of the plant depends largely on its health when is planted on the field. Moreover, organic agriculture has to deal with the low application of fertilizers and pesticides, which hinder the growth of seedlings. In this work, we studied the big influence of different mixtures of substrates suitable for organic agriculture based on peat, coconut husk and vermicompost in traditional varieties of tomato, pepper and eggplant. Our results indicate that the use of coconut husk based substrates in organic agriculture can reduce the growth of seedlings between 20 and 30% compared with peat-based substrates. Moreover, the plants growth in this substrate showed lower levels of chlorophyll and lower weight, but the results are strongly dependent on the species tested. Comparison between traditional plants demonstrates that traditional varieties are strongly influenced by the substrate, whereas the growth of a commercial variety of tomato barely differs when different substrates are used. The election of the substrate in organic agriculture is critical to the correct development of the plant, especially when traditional plant varieties are used. (Author)

The number of web based platforms for crop monitoring has grown rapidly over the last years and anomaly maps and time profiles of remote sensing derived indicators can be accessed online thanks to a number of web based portals. However, while these systems make available a large amount of crop monitoring data to the agriculture and food security analysts, there is no global platform which provides agricultural production hotspot warning in a highly automatic and timely manner. Therefore a web based system providing timely warning evidence as maps and short narratives is currently under development by the Joint Research Centre. The system (called "HotSpot Detection System of Agriculture Production Anomalies", HSDS) will focus on water limited agricultural systems worldwide. The automatic analysis of relevant meteorological and vegetation indicators at selected administrative units (Gaul 1 level) will trigger warning messages for the areas where anomalous conditions are observed. The level of warning (ranging from "watch" to "alert") will depend on the nature and number of indicators for which an anomaly is detected. Information regarding the extent of the agricultural areas concerned by the anomaly and the progress of the agricultural season will complement the warning label. In addition, we are testing supplementary detailed information from other sources for the areas triggering a warning. These regard the automatic web-based and food security-tailored analysis of media (using the JRC Media Monitor semantic search engine) and the automatic detection of active crop area using Sentinel 1, upcoming Sentinel-2 and Landsat 8 imagery processed in Google Earth Engine. The basic processing will be fully automated and updated every 10 days exploiting low resolution rainfall estimates and satellite vegetation indices. Maps, trend graphs and statistics accompanied by short narratives edited by a team of crop monitoring experts, will be made available on the website on a

Full Text Available The economic position of the agricultural sector of the Krasnodar region and the place of small business in economy of the region is considered. It is noted that in structure of agricultural production of the country today the region produces 8%, in gross regional product – about 13% of the total material production. The main share of agricultural production is still produced by agricultural organizations, in 2013, they generated more than 61% of total production, farm population - 24%, domestic farms - 15%. Regional plant growing today produces more than 72% of all agricultural products. In the sphere of animal husbandry, the authors recommend stabilizing dairy herd, to restore the normal functioning of pig farms, build and reconstruct farms and complexes, to increase the supply of quality feeds, to restore the productivity of animals and poultry, the quality level of the staffing industry. It is noted that the production of milk has become a pretty beneficial business; its profitability has risen to 37%. But meat production remains unprofitable due to weak motivation of investing, and problems with lending. There are also serious problems in technical support, especially to the sector of small farm management. As a result, producers suffer from significant financial losses due to the great timing of major agricultural companies. Attention is drawn to the unused opportunities of leasing machinery and equipment, negative policy of low wages for rural workers, and high number of farms which are in bankruptcy proceedings. To increase the stability of development of the agrarian economy, the authors recommend taking into account the peculiarities of financial-economic activity of small rural businesses

Full Text Available In the first half of the nineteenth century, agriculture in Russia had reached the new level of development. The Imperial Agricultural Societies paid much attention to establishing relations with the foreign agricultural societies and kept up with their periodicals, issuing translations and abridgements of texts, which could be interesting to the Russian readers. This paper examines the articles on farming industry in Great Britain, France, German countries, Italy, and the USA, released in journals and transactions of Imperial Agricultural Societies of Russia in 1840s. The research draws on both reviews of European congresses or exhibitions, written by members of agricultural societies, and the articles written by foreign authors and published in translation. Such approach made it possible to specify the certain topics appealing to Russian farmers. Moreover, the study of the articles contributed by the Imperial Agricultural Societies helped to build a complete picture representing knowledge on history, theory and practice of foreign and Russian husbandry, shared by the Russian farmers in 1840s. It is also worth to mention that the effective work of agricultural journals in fact integrated Russian farming communities into the broad network of contacts, experience and knowledge exchange, which had been functioning in Europe in the first half of the XIXth century. Nevertheless, the research revealed that the articles in question almost lacked comparisons between Russian and European agriculture. The papers dealing with comparative analysis of the different European farming systems are characterized by noticeably restrained reaction of the editors and authors to the published information. They tended to show the advantages and disadvantages of the foreign farming without furnishing the Russian reader or the Russian authorities with any specific recommendations.

The bulk of developing countries' populations and poor depend on agriculture for food and income. While rural economies and people are generally the most severely affected by natural disasters, little is known about how disasters and subsequent relief activities affect agricultural markets with differing levels of development. The article addresses this gap, drawing evidence from bean seed markets in Honduras after Hurricane Mitch. Case studies are used to address hypotheses about a disaster's effects on supply and demand in seed markets, farmers' responses and the performance of relief interventions in markets showing differing levels of development. The results show the importance of tailoring relief interventions to the markets that they will affect and to the specific effects of a disaster; the potential to use local and emerging seed distribution channels in a relief intervention; and opportunities for relief activities to strengthen community seed systems.
Full Text Available Great Recession is another proof that the current paradigm of economic growth should be changed. It ought to be applied to all sectors, including agriculture. The farming sector was strongly affected by substantial price increases of some products. It was especially painful for poorer consumers in developing and Third World countries, while its benefits were channelled mainly to big farmers and speculators in developed economies. Common Agricultural Policy could not avert this turbulence. The implementa-tion of the concept of sustainable development is a possible solution of this problem as its approach is more holistic and humanistic. However, the implementation of adequate reforms is very slow. It is a sign that leading US and EU policymakers attempt to stay within the limits of current model of growth.However, the second wave of price hikes may prove to be more lasting, which would further deepen income inequality.
In 2005, the Economic Union of West African States (ECOWAS) decided to create a common agricultural policy (ECOWAP), with food sovereignty and the promotion of efficient family farms as its main aims. The structure and instruments of the policy still have to be elaborated. Because the ECOWAS countri

Currently, there is a major concern about the future of nutrient loads discharged into the Baltic Sea from Polish rivers because they are main contributors to its eutrophication. To date, no watershed-scale studies have properly addressed this issue. This paper fills this gap by using a scenario-modeling framework applied in the Reda watershed, a small (482 km²) agricultural coastal area in northern Poland. We used the SWAT model to quantify the effects of future climate, land cover, and management changes under multiple scenarios up to the 2050s. The combined effect of climate and land use change on N-NO3 and P-PO4 loads is an increase by 20-60 and 24-31 %, respectively, depending on the intensity of future agricultural usage. Using a scenario that assumes a major shift toward a more intensive agriculture following the Danish model would bring significantly higher crop yields but cause a great deterioration of water quality. Using vegetative cover in winter and spring (VC) would be a very efficient way to reduce future P-PO4 loads so that they are lower than levels observed at present. However, even the best combination of measures (VC, buffer zones, reduced fertilization, and constructed wetlands) would not help to remediate heavily increased N-NO3 loads due to climate change and agricultural intensification.

Full Text Available Problem statement: An understanding of factors influencing entrepreneurial education in Irans applied-scientific educational centers for agriculture is crucial for creating the new opportunities for students and encouraging them to involve in entrepreneurial activity. The purpose of this study was twofold. First, it determined the key factors that influence entrepreneurial education in Irans applied-scientific educational centers for agriculture. Second, the study examined relationship of these factors with developing entrepreneurial education. Approach: The research in terms of nature is a kind of quantitative research and in terms of goal is applied research, in terms of controlling the variables is descriptive and correlation kind, which has been carried out in a survey way. Statistical population of the study consisted of 19255 students for applied-scientific education in agriculture in Iran. Based on the classification of the Ministry of Agriculture which has divided these centers into five regions, sample taking has been conducted using stratified proportionate random sampling technique. Sample size for the students is 355 people using Cochran formula. Considering the entire size of the sample, some 291 questionnaires have been returned. Results: The results of the ordinal factor analysis showed the classification of the factors into five latent variables. The variables were classified into managerial, economical, social, technical and regulatory. The basic idea of factor analysis was to found a set of latent variables that contain the same information. The classic factor analysis assumed that, both observed and the latent variables were continuous variables. But, in practice, the observed variables were often ordinal. Spearman coefficient showed that there was relationship between economical, social, technical, regulatory and managerial factors and perception of students about entrepreneurial education. Conclusion: Entrepreneurial
The Three Gorges Project attracts worldwide attention because of the Three Gorges migrants, and the agriculture of the Three Gorges Reservoir Area is a foundation for the development of the Three Gorges migrants.

Much of the research on the recent resurgence of malaria in Third World areas has focused on the problem of vector resistance arising out of the widespread use of pesticides in conjunction with the development of large-scale agricultural projects. Evidence from southern Africa, and particularly from Swaziland, where a resurgence of malaria has occurred in the absence of pesticide-resistant strains of Anopheles mosquitoes, suggests that changes in agroecosystems, labor utilization and settlement patterns, which are also associated with large-scale agricultural development, may play an equally important role in the resurgence of malaria. Renewed efforts to control malaria must, therefore, take account of the social and economic, as well as the biological determinants of this disease.
@@ Introduction "Agriculture" could be defined as the human activity of obtaining a larger volume of food and raw materials from a limited land area in order to sustain a growing population. To accomplish this, humans must transform an ecological system of nature into a partly man-made ecological system of arable land. In this ecological system of arable land, crops that require human assistance are predominant, and any other wild species are generally considered undesirable, and so are removed. There are significantly fewer species in an ecological system of arable land than in an ecological system of nature, and the interrelationship among species is weaker. Given these facts,agriculture is in effect accompanied by the destruction of nature, and cannot be said to contribute to the protection of the environment.

On the Loess Plateau of China, facing the vulnerable environment, local people have to try their best to guarantee the security of food, and at the same time, to control the most serious soil erosion in the world. The paper introduces two typical models of ecological agriculture: ecological agriculture with commodity and agriculture with soil and water conservation. According to the local natural condition, the model of eco-agriculture with commodity could be characterized by the structure of “agriculture-byproduct”, “agriculture-fruit” or “agriculture-forestry-husbandry”. The development of agriculture with soil and water conservation has decreased the soil erosion rate from 12, 184 ton/kin2 in 1980 to 458.4 ton/kin2 in 1999, while the farmers' income has increasingly risen. Analyses on the two models' benefits both in terms of ecological and agricultural economy show that there is a great possibility to construct or restore good eco-environment with comprehensive control in the hilly-gully area of north Shannxi. Further more, the paper points out the potential problems of foodstuff production and stockbreeding development in forming ecological agriculture and eco-environmental restoration.

This study aims to examine the impact of the China-ASEAN Free Trade Area (CAFTA) on China's international agricultural trade and its regional agricultural development, using the Global Trade Analysis Project model and the China Agricultural Decision Support System. Our analysis showed that: (i) CAFTA will improve resource allocation efficiencies for both China and ASEAN and will promote bilateral agricultural trade and, hence, will have positive effects on the economic development of both sides; (ii) CAFTA will accelerate China's export of the agricultural commodities in which it has comparative advantages,such as vegetables, wheat and horticultural products, but at the same time bring about a large increase in imports of commodities such as vegetable oil and sugar; and (iii) CAFTA will have significantly varying impacts on China's regional agricultural development because of large differences in the agricultural production structure in each region. Our results indicate that agriculture in the northern, northeastern and eastern regions of China will benefit from CAFTA, whereas agriculture development in southern China will suffer Those regional specific impacts are quite different from the effects brought by multilateral free trade treaties, such as those of the WTO, which usually have positive effects on south China but negative impacts on the northern and western parts of China.

Full Text Available The most important right bank tributary of the Putna River in the Land of Vrancea, the Zăbala River, springs from the main orographic node of the Vrancea Mountains and crosses the mountain area to create, at the contact between the mountains and the Sub-Carpathian region, a depression area which represented the habitational and economic support for the formation of the Land of Vrancea. One of the main economic activities developed within the Zăbala River basin is agriculture, a traditional occupation and at the same time a possible basis for a sustainable development. In the current paper, we have made an analysis of the main parameters which influence the practice of agriculture, as well as of the possibilities for the development of other agricultural activities depending on the characteristics of the available land fund, on the technological facilities and on the existing human resource by taking into consideration the structure and characteristics of the two current branches of the primary sector of activity.

The countries of the world's humid tropical regions lack the soil fertility necessary for high agricultural productivity. A recently developed agricultural technology that increases soil fertility can make tropical agriculture highly productive, but the technique requires large inputs into the soil of phosphorus and other fertilizers and soil amendments. Use of fertilizers derived from phosphate rock is increasing greatly throughout the world, and fertilizer raw materials are being produced more and more frequently from phosphate rock deposits close to the areas of use. An increased understanding of the origin of phosphate rock in ancient oceans has enabled exploration geologists to target areas of potential mineral resource value and to search directly for deposits. However, because of the difficulty of prospecting for mineral deposits in forested tropical regions, phosphate rock deposits are not being explored for in the countries of the humid tropics, including most countries of the Caribbean region. As a result, the countries of the Caribbean must import phosphate rock or phosphorus fertilizer products. In the present trade market, imports of phosphate are too low for the initiation of new agricultural technology in the Caribbean and Central American region. A newly proposed program of discovery and development of undiscovered phosphate rock deposits revolves around reconnaissance studies, prospecting by core drilling, and analysis of bulk samples. The program should increase the chance of discovering economic phosphate rock deposits. The search for and evaluation of phosphate rock resources in the countries of the Caribbean region would take about 5 years and cost an average of $15 million per country. The program is designed to begin with high risk-low cost steps and end with low risk-high cost steps. A successful program could improve the foreign exchange positions of countries in the Caribbean region by adding earnings from agricultural product exports and

Knowledge systems-networks of linked actors, organizations, and objects that perform a number of knowledge-related functions that link knowledge and know how with action-have played a key role in fostering agricultural development over the last 50 years. We examine the evolution of the knowledge system of the Yaqui Valley, Mexico, a region often described as the home of the green revolution for wheat, tracing changes in the functions of critical knowledge system participants, information flows, and research priorities. Most of the knowledge system's key players have been in place for many decades, although their roles have changed in response to exogenous and endogenous shocks and trends (e.g., drought, policy shifts, and price trends). The system has been agile and able to respond to challenges, in part because of the diversity of players (evolving roles of actors spanning research-decision maker boundaries) and also because of the strong and consistent role of innovative farmers. Although the agricultural research agenda in the Valley is primarily controlled from within the agricultural sector, outside voices have become an important influence in broadening development- and production-oriented perspectives to sustainability perspectives.

Mind, Self, and Society, the posthumously published volume by which George Herbert Mead is primarily known, poses acute problems of interpretation so long as scholarship does not consider the actual process of its construction. This paper utilizes extensive archival correspondence and notes in order to analyze this process in depth. The analysis demonstrates that the published form of the book is the result of a consequential interpretive process in which social actors manipulated textual documents within given practical constraints over a course of time. The paper contributes to scholarship on Mead by indicating how this process made possible certain understandings of his social psychology and by relocating the materials that make up the single published text within the disparate contexts from which they were originally drawn.

According to the contemporary ecosystem approach, the linkages of human actions with their environment have to be assessed in an integrative manner. The Driver-Pressure-State-Impact-Response (DPSIR) model is applied to identify and describe processes and interactions in human-environmental systems. An example application from a research project dealing with the development of sustainable management strategies for the agriculture in Jiangsu, China, illustrates the potentials and limitations of its sustainable development. The concept and indicators of ecological integrity are used to assess the indicators in the dimensions of DPSIR between 2003 and 2006. The main drivers included population growth which caused increasing demand for food, growing environmental demands, and rapidly decreasing of land and other natural resources. The main environmental problem was water pollution. The results show that in the dimension of driver, total grain output and agricultural land productivity both increased. Labor intensive agriculture has been promoted to increase agricultural land productivity. In the dimension of pressure, on the positive side, infrastructure got greatly improved, the input level such as total power of machinery, and level of fertilizer use increased, and level of pesticides use decreased, but on the negative side, cultivated land per capita and irrigation rate decreased, natural resources keep decreased. Environmental pollution indicators such as industrial wastewater discharge and acid rain rate increased in Jiangsu Province. In the aspect of state, ecosystem state was improved, plant coverage index increased, biological abundance index increased, fertilizer productivity increased, eco-environmental quality index increased, but land degradation index also increased. In the aspect of impact, output level increased, output efficiency enhanced, farmer’s social economic benefit improved. In the aspect of response, social support was greatly improved, input

Agricultural systems differ significantly throughout the world, making a 'one size fits all' approach to remote sensing and monitoring of agricultural landscapes problematic. The Joint Experiment for Crop Assessment and Monitoring (JECAM) was established in 2009 to bring together the global scientific community to work towards a set of best practices and recommendations for using earth observation data to map, monitor and report on agricultural productivity globally across an array of diverse agricultural systems. These methods form the research and development component of the Group on Earth Observation Global Agricultural Monitoring (GEOGLAM) initiative to harmonize global monitoring efforts and increase market transparency. The JECAM initiative brings together researchers from a large number of globally distributed, well monitored agricultural test sites that cover a range of crop types, cropping systems and climate regimes. Each test site works independently as well as together across multiple sites to test methods, sensors and field data collection techniques to derive key agricultural parameters, including crop type, crop condition, crop yield and soil moisture. The outcome of this project will be a set of best practices that cover the range of remote sensing monitoring and reporting needs, including satellite data acquisition, pre-processing techniques, information retrieval and ground data validation. These outcomes provide the research and development foundation for GEOGLAM and will help to inform the development of the GEOGLAM "system of systems" for global agricultural monitoring. The outcomes of the 2014 JECAM science meeting will be discussed as well as examples of methods being developed by JECAM scientists.

Aerial photographs were used to generate DEM,and a set of terrain analysis methods were employed to calculate hydrological parameters that are needed for the pesticide loss model. The system also facilitates convenient management and presentation of vast amounts of modeling inputs and outputs through user interfaces. A case study in the Kintore Creek Watershed,Ontario,Canada was undertaken to provide bases for environmental management in the watershed and to demonstrate practical applicability of the developed DSS. The modeling outputs were verified through monitoring data,demonstrating reasonable prediction accuracy. The result indicated that the model provides an effective means for forecasting pesticide losses from agriculture lands. Especially,incorporation of GIS and remote sensing with the pesticides losses model provide a powerful tool for system simulation and environmental management. The major contribution of this study is the development of a new integrated modeling system for simulating fate of pesticides in agricultural lands,as well as its application to a real Canadian case study. In detail,a dynamic simulation model was developed,a solution algorithm was implemented,and the modeling results were verified. The developed simulator was also enhanced through incorporation of GIS and RS technologies within its framework to facilitate effective data acquisition and management,as well as input/output presentation.

Our overarching hypothesis is that new risks, in this case the H5N1 strain of avian influenza, emerge during transitions between stages of development. Moreover, these risks are not coincidental but occur precisely because of the in-between nature of the coupled human-natural system at the point when things are neither traditional nor modern but resemble the state of chaos, release and reorganization. We are testing this hypothesis in Vietnam using demographic, social, economic, and environmental data collected in national censuses and analyzed at commune and district levels to identify communes and districts that are traditional, modern, and transitional (peri-urban). Using data from the 2006 agricultural census that capture both the changing nature of the built environment (types of sanitation systems) and the loss of and diversification of agriculture systems (percent of households whose major source of income is from agriculture, and percent of land under agriculture, forests, and aquaculture), and a normalized difference vegetation index from 2006 Landsat images we created a national scale urbanicity map for Vietnam. Field work in the summer of 2011 showed this map to be an accurate (approximately 85%) approximation of traditional (rural), transitional (periurban), and modern (urban) communes. Preliminary results suggest that over 7% of the country's land area and roughly 15% of its population resides in periurban neighborhoods, and that these areas do have a statistically significant greater incidence of AVI as measured in chicken deaths than traditional and modern communes (Table 1). Transitional neighborhoods such as these force planners to ask two questions. To what extent does the dichotomy of urban/rural makes sense in the context of Vietnam, when large areas and parts of the population are caught between the two? Second, how can planners and policy makers effectively provide for basic public goods and services in these contexts?Classification of places
This article introduces the status quo of consumer credit business in China’s agricultural bank,indicating that the scale of China’s consumer credit business is expanded year by year;the growth of consumer credit business slows down;housing loans grow rapidly.We analyze issues concerning development of consumer credit business in agricultural bank as follows:single variety of consumer credit business makes the operating scope narrow;the formality of consumer credit business is trivial,abating consumers’ will to borrow;consumers’ consumer attitudes are stale,yet to be further changed;the loan interest of consumer credit is beyond the majority of consumers’ actual ability to pay;the existing regulations and systems are not sound;the risk prevention mechanism is not perfect.Based on this,we put forward the following countermeasures and proposals for further improving consumer credit business in China’s agricultural bank:first,formulate reasonable marketing strategy of consumer credit business;second,establish and improve the internal management mechanism;third,establish and improve risk assessment system;fourth,improve consumer credit legal system.
Full Text Available Republic of Serbia consumes about 15 million tons of equivalent oil per year (Mtoe. At the same time potential of the renewable energy sources is about 3,5 Mtoe/year. Main renewable source is biomass, with its potential of about 2,6 Mtoe/year, and 60% of the total biomass source is of agricultural origin. Mainly, that type of biomass is collected, transported and stored in form of bales. At the same time in one of the largest agricultural companies in Serbia (PKB there are over 2000 ha of soya plantations, and also 4000 t/year of baled soya straw available, none of which being used for energy purposes. Therefore, efforts have been made in the Laboratory for Thermal Engineering and Energy of the "Vinča" Institute to develop a technology for utilizing bales of various sizes and shapes for energy production. Satisfactory test results of the 1 MW experimental facility - low CO levels and stable thermal output - led to the building-up of a 1.5 MW soya straw bales-fired hot water boiler, with cigarette type of combustion, for the purposes of greenhouse and office heating in the PKB. Further more, achieving good results in exploitation of that hot water boiler, the next step is building up the first combined heat and power (electricity production facility (CHP, which will use agricultural biomass as a fuel, in Serbia.

Full Text Available This article presents a proposal of historical periodization regarding the use of pesticides and other agrochemicals products in the Valley of Mexicali, taking into account the evolution of regional agricultural development and its context. The use of diverse chemical products in agriculture was the result of industrial an technological models which were adopted at the beginning of the twentieth century and, in particular, as a resul of suggestions arising out of the "green revolution". We highligt the importance of vegetables as a primary consumer of pesticides. We also note that, in spite of the use of agrochemical products in the Valley of Mexicali for various decades, little research has been done regarding the effects on public health and the environment. What little information has been gathered from studies carried out in agricultural zones utilizing these products is alarming. Therefore, we underline the need to carry out research that delves more deeply into long-term effects of the use of such products.

Full Text Available Implementing agricultural water management programs over appropriate spatial extents can have positive effects on water access and erosion management. Lack of access to water for domestic and agricultural uses represents a major constraint on agricultural productivity and perpetuates poverty and hunger in sub-Saharan Africa (SSA. This lack of access is the result of erratic precipitation, poor water management, limited knowledge of hydrological systems, and inadequate investment in water infrastructure. Water management programs should be made by multi-disciplinary teams that consider the interrelationship between hydraulic and anthropogenic factors. This paper proposes a method to prioritize watersheds for water management and agricultural development across Mali (Western Africa using remote sensing data and GIS tools. The method involves deriving a set of relevant thematic layers from satellite imagery. Satellite images from Landsat ETM+ were used to generate thematic layers such as land use/land cover. Slope and drainage density maps were derived from Shuttle RADAR Topography Mission (SRTM Digital Elevation Model (DEM at 90 m spatial resolution. Population grids were available from the Global rural-urban mapping project (GRUMP database for the year 2000 and mean rainfall maps were extracted from Tropical rainfall measuring mission (TRMM grids for each year between 1988 and 2014. Each thematic layer was divided into classes that were assigned a rank for agriculture and livelihoods development provided by experts in the relevant field (e.g., Soil scientist ranking the soil classes and published literature on those themes. Zones of priority were delineated based on the combination of high scoring ranks from each thematic layer. Five categories of priority zones ranging from “very high” to “very low” were determined based on total score percentages. Field verification was then undertaken in selected categories to check the priority
Full Text Available Problem statement: The movement of technology from lab to the field has been a challenge for agricultural extension agents. In this study researchers focused on program development competencies for agricultural extension agents in process of technology transfer and discuss the importance of these competencies by determining the relationship between these competencies and performance of extension agents. Approach: The study employed stratified random sampling technique. The sample consisted of 210 extension agents in four states of Malaysia. The data were analyzed using descriptive statistics, Pearson correlation and multiple regression analysis. Results: Extension agents perceived themselves competent in developing program planning, program implementation and program evaluation. The findings supported the positive relationship between competencies and extension agents performance. Therefore hypothesis of the study was supported. The results of multiple regressions showed program development competencies explained 0.448 of variance of extension agents performance. Conclusion/Recommendations: It can be concluded that performance of extension agents is expected to increase if they have program development competencies. Results supported the importance of these competencies for performance of extension agents in process of technology transfer. Hence to keep extension agents competent and to further improve their performance, these competencies must be considered and upgraded. Continuous assessment of extension agents competencies and performance is recommended.

Municipal and urban land-use intensification in coming decades will place increasing pressure on water resources in California. The state is currently experiencing one of the most extreme droughts on record. This coupled with earlier spring snowmelt and projected future climate warming will increasingly constrain already limited water supplies. The development of spatially explicit models of future land use driven by empirical, historical land use change data allow exploration of plausible LULC-related water demand futures and potential mitigation strategies. We utilized the Land Use and Carbon Scenario Simulator (LUCAS) state-and-transition simulation model to project spatially explicit (1 km) future developed and agricultural land use from 2012 to 2062 and estimated the associated water use for California's Mediterranean ecoregions. We modeled 100 Monte Carlo simulations to better characterize and project historical land-use change variability. Under current efficiency rates, total water demand was projected to increase 15.1% by 2062, driven primarily by increases in urbanization and shifts to more water intensive crops. Developed land use was projected to increase by 89.8%-97.2% and result in an average 85.9% increase in municipal water use, while agricultural water use was projected to decline by approximately 3.9%, driven by decreases in row crops and increases in woody cropland. In order for water demand in 2062 to balance to current demand levels, the currently mandated 25% reduction in urban water use must remain in place in conjunction with a near 7% reduction in agricultural water use. Scenarios of land-use related water demand are useful for visualizing alternative futures, examining potential management approaches, and enabling better informed resource management decisions.
The development and prospect of rare earth functional biomaterials (REFB) was discussed. From 1979 to 1985, the simple REFB (salts) has been developed, and the fundamental research including forms, effects, toxicity, conversion in soil, and analysis methods had been finished. Then, the RE feed additive materials had been developed, and the fundamental research had also been finished. In 1990s, new REFB including RE phosphate fertilizer additive, RE conversional agricultural film additive, RE water-retraining reagent and RE seed coating reagent had been developed out rapidly. They were extended to 1.36 million hectares and big benefit had been got during the last three years. Recently, it was found that RE has some function of antagonizing heavy metals and degradating organophosphors pesticide, so the REFB will be studied as a focus once more, and will become one of the important methods of guaranteeing food security in the future.

Biotechnology is a controversial subject that involves a range of scientific principles from basic tissue culture to genetic manipulation. Proponents include private sector capitalists, public sector researchers, and developing nation governments. Opponents include environmental organizations and social organizations involved in protecting the rights of developing nations. Biotechnology is being presented as the next step after the Green Revolution and the only way that the people of the developing world will be able to feed themselves in the next half century. Research by industrialized nations world wide total an estimated $11 billion with 66% being contributed by the private sector. Biotechnology represents somewhat of a dilemma. Since the majority of the work is being done by the private sector the interests of shareholders and profit are greater done by the private sector the interests of shareholders and profit are greater than that of public welfare or safety. The Consultative Group on International Agricultural Research (CGIAR) is one public sector group that is concerned about this problem. The countries of the developing world fall into 2 categories in relation to use of biotechnology: (1) those that have the potential to adapt imported biotechnologies to local conditions; (2) those that have little or no applied research capacity to effectively use biotechnologies. Currently only Brazil, China, India, and Thailand belong in the 1st category, all other developing countries fall into the 2nd. CGIAR believes it can help in 2 ways: (1) it can provide a bridge for needed information and germplasm between developed and developing countries; (2) it can help to ensure that the agricultural needs of developing countries are not lost. In 1990 CGIAR's plant and animal biotechnology research totaled $14.5 million which was less than 5% of the total CGIAR budget. Networking and institutions building are areas that CGIAR focuses on in an attempt to increase its affect

The Public Intellectual Property Resource for Agriculture (PIPRA) was founded in 2004 by the Rockefeller Foundation in response to concerns that public investments in agricultural biotechnology benefiting developing countries were facing delays, high transaction costs and lack of access to important technologies due to intellectual property right (IPR) issues. From its inception, PIPRA has worked broadly to support a wide range of research in the public sector, in specialty and minor acreage crops as well as crops important to food security in developing countries. In this paper, we review PIPRA's work, discussing the failures, successes, and lessons learned during its years of operation. To address public sector's limited freedom-to-operate, or legal access to third-party rights, in the area of plant transformation, we describe PIPRA's patent 'pool' approach to develop open-access technologies for plant transformation which consolidate patent and tangible property rights in marker-free vector systems. The plant transformation system has been licensed and deployed for both commercial and humanitarian applications in the United States (US) and Africa, respectively.
Full Text Available To improve the incomes of farmers in China, the Chinese government is paying increased attention to the reform of its agricultural subsidy policy. However, the effectiveness of the subsidy remains insufficient and thus fails to encourage farmers to cultivate their land and develop sustainability. Thus, there is a need for a novel model that will improve the effectiveness and efficiency of subsidies. The proposed novel agricultural subsidy model comprises four major actors: farmers, specialized farmers’ cooperatives, agribusiness and government. Furthermore, the subsidy in this novel model would no longer go directly to farmers but to the agribusiness. To develop the model, the empirical data for this study are obtained from a Chinese agribusiness in Liaoning Province that was selected as a benchmark. With this novel model, farmers receive triple rebates: the price received when the rice is initially sold; a share of the profits of the specialized farmers’ cooperatives; and a share of the profits of the agribusiness. Accordingly, exploring the optimal subsidy rate for agribusinesses is the critical task of this study, and the results demonstrate that agribusinesses must use the government subsidy policy as the basis for a dynamic subsidy model that ensures the income of farmers and encourages sustainable development.

The farming is one of the most important branches that bring the increase to the gross internal production in Bulgaria. At the same time, the agriculture is the only branch, as in home, so in world scale in which the made as well direct production spending and investing regenerating (or not) only in the frameworks to one vegetative season. In addition on this, development of the intensive farming without using the most advanced technologies such as irrigation, automation, selection - for obtaining stable cultivars and hybrids, permanent weather monitoring and agroclimatic zoning and integrated and biochemical protection to the cultures and plantations had not possible. Analysis of long-term meteorological data from different regions shows clear tendencies to warming and drying for the period of contemporary climate (1971-2000) as well in Bulgaria. Hydro-meteorological conditions in the country are worsened. The most entire estimate is made from the Intergovernmental Panel for Climate Change (IPCC) 2007. Most of authors proven that the last decades are really warmest for last century, even for the entire period of the most instrumental observations. The causes for global warming was long time debatable, but the last investigations prove it anthropogenetic derive.

Based on the rural economic data pertaining to the development of rural finance, the growth of agricultural economy and farmers’ income in Jiangxi Province during the period 1990-2009, we conduct empirical research on the impact of development of rural finance on the growth of agricultural economy and farmers’ income, using the ADF test method, the Granger causality test, and regression analysis. The results show that the development of rural finance in Jiangxi Province has a significant positive effect on the growth of rural economy and farmers’ income. When the ending balance of agricultural loans increases by 1 unit, the agricultural added value will increase by 0.367 1 units; when the ending balance of agricultural loans increases by 1 unit, farmers’ income will increase by 0.597 5 units, indicating that the development of rural finance plays a significant role in promoting the per capita net income of farmers.Finally we propose to increase agricultural credit efforts in the financial institutions, establish and improve the agricultural credit management system.

Full Text Available Structural change consists of the long-term changes in the sectoral composition of output and employment. We introduce a structural change perspective to the study of income inequality in 27 countries of the developing world for the period 1960-2010. The service sector has become the main employer, but the agricultural sector is central to the income distribution because poverty is mostly rural, and the labor surplus is high. We decompose the sectoral composition of aggregate labor productivity at the country level, divide the countries into agrarian, dual (beginner, intermediate and advanced, and mature economies and use the inter-sectoral productivity gap to test the effect of structural change on income inequality. We confirm increases in agricultural productivity everywhere and find that the inter-sectoral gap is positively associated with income inequality. The effect is negligible in agrarian and advanced economies but powerful in dual beginner economies: an increase of 1% in the inter-sectoral gap increases income inequality by 0.5%. The effect peters out in dual intermediate economies and disappears completely in dual advanced economies. Finally, redistribution has been the key to compensating the losers in the income changes, particularly for those entering the non-agricultural economy.

Full Text Available lt is necessary to reconsider the paradigm of development followed by nations as well as the concept of human welfare. The United Nations Development Plan (UNDP is an alternative, taking into account that it focuses its approach on the humanistic axis. Although it has been debated but not completely accepted by the main world powers, it is evident that a new system in which human beings are able to reach equality should be promoted, and in which the difference between rich and poor could be counteracted. This article tries to make a reflection on this alternative model and gives some guidelines for the education in the agricultural sector, to educate professionals interested in the sustainable human development as La Salle University does.

Full Text Available Problem statement: Integrated Agricultural Development Project (IADP is a platform for rural socioeconomic improvement. This initiative has raised the income of farmers by creating a large scale fruits producer in Sarawak. Therefore, the objective of this study was to identify the direct impact of the agricultural development project on socioeconomic improvement in the Samarahan area. Approach: This study involved 14 villages and is located in the Mid-Samarahan and Upper Samarahan areas. A total of 220 households were interviewed during December 2005-February 2006 to collect information on yield and household income. The paired t-test analysis showed that the project had a positive impact on in-farm and other incomes of farmers. Results: It was also revealed that the poverty level of Sarawak state was reduced from the poverty line, from 77% in 1986-19.5% in 2005. The percentage of hard core poverty fell from 30.9% in 2000-6.4% in 2005. Conclusion: The project was generally implemented as an appraisal to increase the incomes of rural population through fruit cultivation as a main economic activity. It was concluded that this project is efficient as a tool to combat poverty and improved the socioeconomic level and income generating activities among the rural community.
Full Text Available The rich natural potential for agriculture in Romania is contrasting with the low level of economic performance. Progress toward sustainable development in rural areas depends on processes that lead to increased valuation of the natural resources by cropping and livestock breeding, capturing more value by growing the number of processing stages performed at national level for food production, improvements in the distribution of benefits with special focus on rural population, harnessing the benefits of stewarding natural ecosystems that play a key role for the overall wellbeing of the population, diversifying the structure of economic activities, and encouraging entrepreneurial involvement. European policies of rural development are supporting most of these processes, but within the national context there encountered specific challenges born by the low level of maturation for property relationships, fragmentation of land ownership and cropping plots, cultural patterns that create strong resistance to change, and lack of financial resources. The paper highlights several aspects in order to assess at what extent the Romanian agriculture is making progress toward European requirements.

Adoption of precision agriculture techniques requires the development of specialized tools that provide spatially distributed information. Both flying platforms and airborne sensors are being continuously evolved to cover the needs of plant and soil sensing at affordable costs. Due to restrictions in payload, flying platforms are usually limited to carry a single sensor on board. The aim of this work is to present the development of a vertical take-off and landing autonomous unmanned aerial vehicle (VTOL UAV) system for the simultaneous acquisition of high resolution vertical images at the visible, near infrared (VNIR) and thermal infrared (TIR) wavelengths. A system was developed that has the ability to trigger two cameras simultaneously with a fully automated process and no pilot intervention. A commercial unmanned hexacopter UAV platform was optimized to increase reliability, ease of operation and automation. The designed systems communication platform is based on a reduced instruction set computing (RISC) processor running Linux OS with custom developed drivers in an efficient way, while keeping the cost and weight to a minimum. Special software was also developed for the automated image capture, data processing and on board data and metadata storage. The system was tested over a kiwifruit field in northern Greece, at flying heights of 70 and 100m above the ground. The acquired images were mosaicked and geo-corrected. Images from both flying heights were of good quality and revealed unprecedented detail within the field. The normalized difference vegetation index (NDVI) was calculated along with the thermal image in order to provide information on the accurate location of stressors and other parameters related to the crop productivity. Compared to other available sources of data, this system can provide low cost, high resolution and easily repeatable information to cover the requirements of precision agriculture.

Conversion of native prairie to agriculture has increased food and bioenergy production but decreased wildlife habitat. However, enrollment of highly erodible cropland in conservation programs has compensated for some grassland loss. In the future, climate change and production of second-generation perennial biofuel crops could further transform agricultural landscapes and increase or decrease grassland area. Switchgrass (Panicum virgatum) is an alternative biofuel feedstock that may be economically and environmentally superior to maize (Zea mays) grain for ethanol production on marginally productive lands. Switchgrass could benefit farmers economically and increase grassland area, but there is uncertainty as to how conversions between rowcrops, switchgrass monocultures and conservation grasslands might occur and affect wildlife. To explore potential impacts on grassland birds, we developed four agricultural land-use change scenarios for an intensively cultivated landscape, each driven by potential future climatic changes and ensuing irrigation limitations, ethanol demand, commodity prices, and continuation of a conservation program. For each scenario, we calculated changes in area for landcover classes and predicted changes in grassland bird abundances. Overall, birds responded positively to the replacement of rowcrops with switchgrass and negatively to the conversion of conservation grasslands to switchgrass or rowcrops. Landscape context and interactions between climate, crop water use, and irrigation availability could influence future land-use, and subsequently, avian habitat quality and quantity. Switchgrass is likely to provide higher quality avian habitat than rowcrops but lower quality habitat than conservation grasslands, and therefore, may most benefit birds in heavily cultivated, irrigation dependent landscapes under warmer and drier conditions, where economic profitability may also encourage conversions to drought tolerant bioenergy feedstocks.

Sensing is an important element to quantify productivity, product quality and to make decisions. Applications, such as mapping, surveillance, exploration and precision agriculture, require a reliable platform for remote sensing. This paper presents the first steps towards the development of a smart flying sensor based on an unmanned aerial vehicle (UAV). The concept of smart remote sensing is illustrated and its performance tested for the task of mapping the volume of grain inside a trailer during forage harvesting. Novelty lies in: (1) the development of a position-estimation method with time delay compensation based on inertial measurement unit (IMU) sensors and image processing; (2) a method to build a 3D map using information obtained from a regular camera; and (3) the design and implementation of a path-following control algorithm using model predictive control (MPC). Experimental results on a lab-scale system validate the effectiveness of the proposed methodology.

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

The overall objective of the project is to provide guidance on how to mainstream responses to climate change within economic development planning and assistance policies, with natural resource management as an overarching theme. This report presents the integrated case study for Tanzania carried out under an OECD project on Development and Climate Change. This report presents the integrated case study for Uruguay carried out under an OECD project on Development and Climate Change. The report is structured around a three-tiered framework. First, recent climate trends and climate change scenarios for Uruguay are assessed and key sectoral impacts are identified and ranked along multiple indicators to establish priorities for adaptation. Second, donor portfolios are analyzed to examine the proportion of development assistance activities affected by climate risks. A desk analysis of donor strategies and project documents as well as national plans is conducted to assess the degree of attention to climate change concerns in development planning and assistance. Third, an in-depth analysis is conducted for adaptation in coastal zones as well as for mainstreaming carbonsequestration within the agriculture and forestry sectors.
Full Text Available The territory of Belgrade city after the Second World War, has been characterized by the intensive processes of qualitative transformation concerning settling and arrangement of population, territorial organization of production and other activities. The facts that mostly influenced these processes are migrations, caused by economic movements and development. There has been a sudden transfer of agricultural population into non-agricultural activities. Participation of agricultural population in total population of Belgrade city has decreased from 29,7% in 1953 to 12,6% in 1971, and to 2,2% in 2002. Participation of active agricultural population in total active population in Belgrade city has decreased from 34,5% in 1953 to 16,3% in 1971, and to 4,1% in 2002. The decrease of the total and active agricultural population is the result of the weakened influence of demographic factors (changes in number and structure of the total and active population, as well as the greater influence of socio-economic factors. The basic tendencies of the future demographic development of agricultural population are influenced by the possibilities of its revitalization, because demographic reserves to from new working powers in agriculture are endangered.

Full Text Available Majority of communities in Nigeria are rural dwellers and agrarian by occupation. Development strategy for a country whose rural population are mainly farmers cannot be achieved without first sustained growth in rural income and standard of living primarily from agriculture. It was based on this that the state wide Agricultural Development Project (ADP was established to raise productivity, income and standard of living of rural farmers in Nigeria. This study assesses the effect of the ADP activities on the wellbeing of the rural farmers in Adamawa State, Nigeria. Data for this study were collect on annual crop output, annual income, farm size, use of improved technology, access to credit among farmers, farmers’ training and rural infrastructure development. The data were sourced using structured questionnaire and personal interviews. The statistical analysis used to determine the effect to the project on the participating farmers include, descriptive statistics and comparability test for difference (T-test analysis. The results indicates that Adamawa ADP had positive and significant impact on rural farmers productivity, income, access to credit, standard of living as measured by assets ownership. However, the project did not have significant impact on the rural infrastructure, adoption of improved technologies and farm sizes, even though the change from before and after ADP activities was positive. The study recommends that much attention should be paid to the provision of rural infrastructure and the needed improved technologies. The study also recommends that the two tiers of government in Nigeria should adequately fund the project to efficiently cope with its responsibility of developing the rural sector.
The importance of agricultural products, their potential conversion to energy sources and their applications for fibre-reinforced construction materials is emphasized. Another potentially important technology is the conversion of sunlight into electricity such as occurs in the leaves of plants. Parallels with nature exist, even though conversions with inorganic materials have, until now, been promising. The ability to control chemical reactions is the subject throughout all the following chapters. The goal is to achieve high reaction efficiencies and to use fewer basic materials, both of which will lead to a reduction in environmental stress. Sustainable developments in chemistry can be described by two approaches: (1) Improvements in society, with challenges for chemistry; and (2) Improvement in the chemical sector itself. Both approaches are dealt with in this report. Five areas for development have been chosen in the discussions for `DTO-Chemie`: Integrated plant conversion (IPC), in particular Valorisation of plant parts for raw materials and energy; Biomass conversion (C1 Chemistry), in particular Technologies for (among others) C1-based chemicals and energy carriers; Photovoltaic cells (PSC), in particular Technologies for the conversion of solar light into electricity; Process Technology in Fine chemistry (PFC), in particular Methodology of manufacturing processes for Fine chemicals; and Sustainable Construction Materials (FRC); in particular Techniques for using fibre-reinforced composites in construction applications. These areas can be viewed as clusters of technologies, with a strong chemistry and agricultural component, which are necessary for achieving a sustainable future. Furthermore, it is important to recognise that technology requires a progressive development (technology lifecycle). The five areas of technology development are tested against a number of criteria: (1) Sustainability / leap / volume; (2) Horizon 2050; (3) Commitment from industry

Farmers in British Columbia (BC), Canada have been shown to have unexplained elevated proportional mortality rates for several cancers. Because agricultural exposures have never been documented systematically in BC, a quantitative agricultural Job-exposure matrix (JEM) was developed containing exposure assessments from 1950 to 1998. This JEM was developed to document historical exposures and to facilitate future epidemiological studies. Available information regarding BC farming practices was compiled and checklists of potential exposures were produced for each crop. Exposures identified included chemical, biological, and physical agents. Interviews with farmers and agricultural experts were conducted using the checklists as a starting point. This allowed the creation of an initial or 'potential' JEM based on three axes: exposure agent, 'type of work' and time. The 'type of work' axis was determined by combining several variables: region, crop, job title and task. This allowed for a complete description of exposures. Exposure assessments were made quantitatively, where data allowed, or by a dichotomous variable (exposed/unexposed). Quantitative calculations were divided into re-entry and application scenarios. 'Re-entry' exposures were quantified using a standard exposure model with some modification while application exposure estimates were derived using data from the North American Pesticide Handlers Exposure Database (PHED). As expected, exposures differed between crops and job titles both quantitatively and qualitatively. Of the 290 agents included in the exposure axis; 180 were pesticides. Over 3000 estimates of exposure were conducted; 50% of these were quantitative. Each quantitative estimate was at the daily absorbed dose level. Exposure estimates were then rated as high, medium, or low based on comparing them with their respective oral chemical reference dose (RfD) or Acceptable Daily Intake (ADI). This data was mainly obtained from the US Environmental
Full Text Available Savu Island is a semiarid region with few rainfalls. The meager annual rainfall of about 1,000-1,500 mm that lasts for three to five months tends to cause draught. To cope with this situation, the Author tries to develop a rainwater management model located in Daieko village. This model constitutes an infrastructure that consists of check dam series which are constructed by simulating a computerized model of decision supporting system called “Rainwater Management for Agriculture Decision Support System (RMA-DSS model” in the research location of Daieko village. Employing a simulated RMA-DSS model; the locations for check-dam series, and dug-wells can be determined, the size of potential irrigable lands can be determined based on water balance analysis of water samples taken from simulated check dams and inundated lands. Through this model the sufficiency of water supply for agricultural purposes and the land size for cultivation area can be predicted with a high degree of certainty.

Nitrate is found in agricultural runoff and natural water sources, and is known to be harmful to humans who ingest it, as well as to aquatic ecosystems into which it is transported. In the interest of simplifying and reducing cost of nitrate detection, we are developing a dedicated nitrate absorption spectrophotometer that is portable, automated, low maintenance, and appropriate for tile drains and agricultural runoff settings, and for natural streams and water bodies. Spectrophotometric and other optical methods for detecting concentrations of given substances have been well studied and implemented for both lab and field applications, but are often expensive and are rarely designed or well suited for long-term in-situ continuous monitoring of settings with low flow or minimal water. Nitrate's absorption spectrum ranges from below 200 nm to approximately 240 nm. Dissolved organic carbon's absorption spectrum overlaps that of nitrate, ranging from below 200 nm to above 300 nm. By taking one absorption reading at a low wavelength within nitrate's peak and a second reading between 240 nm and 300 nm, we see contributions of each substance. With a rough knowledge of the composition of samples of interest, this instrument is able to step outside the absorption spectra of expected interfering species, while staying within nitrate's peak, effectively measuring exclusively nitrate and dissolved organic carbon.

The priorities of public health and agricultural sciences intersect through a shared objective to foster better human health. Enhancements in food quality and reductions in the environmental effects of modern agriculture represent 2 distinct paths through which animal sciences can contribute to the cause of public health. Recent developments in the study of human-associated microbial communities (microbiotas), notably in association with disease, indicate that better understanding of the microbial ecology of livestock can contribute to achieving the goals of better foods and a cleaner environment. Culture-independent microbiological technologies now permit comprehensive study of complex microbial communities in their natural environments. Microbiotas associated with both humans and animals provide myriad beneficial services to their hosts that, if lost or diminished, could compromise host health. Dysfunctional microbial communities have been noted in several human conditions, including inflammatory bowel disease, obesity, and antibiotic-associated diarrhea. Examination of the mechanisms by which the human microbiota influences health and disease susceptibility can inform similar studies of host-microbe function in the animal sciences. Insights gained from human studies indicate strategies to raise not only healthier livestock, through selective manipulation of microbial communities, but also healthier humans.

Full Text Available The paper reports a study carried out on the utilisation of the Internet by agricultural science teachers in Lagos state focusing on uses, practices, and barriers. A questionnaire was developed based on literature and was administered to 300 agricultural science teachers in Lagos schools. 275 questionnaires properly completed were analyzed. Data reveal that 130 teachers are using the Internet for teaching agricultural science in classrooms as well as for various activities that enhance their professional development. Nevertheless, it was found that agricultural science teachers in Lagos State have not fully utilised the Internet because of barriers related to time factor, accessibility, and facilities. It is suggested that for the proliferation of Internet practices, there needs to be an increase in funding for technology, an introduction of computer/technology education, a provision of pedagogical training for teachers, and a provision of administrational support.

Despite the great progresses of the last century in the agricultural sector and food supply, still about 820 million of people in developing countries are facing food scarcity and malnutrition. More than 180 million children are underweight. Except in Africa, 80 percent of the production gains came from increased yields in major cereal crops. The area cultivated has actually begun to decline in some regions. From now on, however, even Africa, which has always relied on cultivation of new land for production increases, will have to count on yield gains or pay high financial and ecological costs for expansion into areas not yet cultivated. The global scenario is changing fast. The technological, climatic and human-induced factors are creating long-lasting effects on the lives of people and on economic activities around the globe. In particular, climate change and/or variability is exacerbating rural increasing heat stress to natural habitats and human settlements, increasing climatic extremes, including drought and impacting food production. Agriculture of any kind is strongly influenced by the availability of water. Climate change will modify rainfall, evaporation, runoff, and soil moisture storage. Changes in total seasonal precipitation or in its pattern of variability are both important. The occurrence of moisture stress during flowering, pollination, and grain-filling is harmful to most crops and particularly so to corn, soybeans, and wheat. Increased evaporation from the soil and accelerated transpiration in the plants themselves will cause moisture stress; as a result there will be a need to develop crop varieties with greater drought tolerance. These climate change effects are particularly harmful in tropical regions of South America, Africa and South East Asia where food production is feeding a large part of world countries and poses serious risks to global food security in the future. Despite global projected climate change will affect a general decline of
From the standpoint of a recent case study on newcomer innovation during organizational entry, G. H. Mead’s theory on becoming a self in community is explored. It is argued that Mead’s concept of the ‘I-me’-dialectic is a key notion in understanding newcomer innovation on process theory terms....... The emphasis on the spontaneous response of ‘I’ in Mead’s theory supplements otherwise dominant assimilation perspectives in the field of organizational socialization, and suggests for understanding newcomer innovation and assimilation not as an ‘either/or’ but a simultaneous process.

Full Text Available Based on the Strategy of Rural Development, the Albanian Government supports directly the agricultural sector. Approximately 3.5 milliard leks have been spent from the state budget. Until now, there has not been an independent evaluation of the efficiency of the use of funds by the government. Such evaluation would be necessary not only to see what is given and how the money are spent, but to have a complete frame and to fully argue the programming of support in the future by respective institutions. Our aim is to identify some of the key outcomes of direct support policy in Fier’s region, to analyze and to evaluate the principles, the effects of supporting schemes as well as to identify the strong and weak points of the subvention scheme from which the direct state support in agriculture would become more effective and efficient. The verification of the effectiveness of the given funds will be achieved through comprehensive analysis described all the way from the application, the selection of applicants, the allocated amount, investment direction, absorption in different times until the final realization. This study was undertaken during 2011 through the development of a standardized methodology. In Fieri region, for 4 years, there have been allocated 435 million leke for direct support to the farmer’s families, respectively: 46 million in 2007, 114 million in 2008, 122 million in 2009 and 153 million lekë in 2010. The projects are invested in olives, vineyards, fruit trees, drip irrigation, greenhouses, livestock, etc. Our study showed that the state support measures for the period 2007-2010 have given significant positive results in the increasing of planted surfaces with fruit trees, olives and vineyards, for their production and productivity. On the other hand the study also showed that for higher grant effectiveness a harmonization of several factors is needed, such as soil, climate studies, seed quality etc.
Governmental functions in agricultural industrialization management are analyzed, mainly including supplying public products, providing property right security, managing and protecting resources and environment as well as stabilizing the agro-product market. The policy orientation promoted by the government in agricultural industrialization management is pointed out: formulating a series of macro-management planning to guide and regulate agricultural industrialization operation; fully playing the comprehensive coordinating role of "economic manager"; making and carrying out relevant laws and regulations to normalize the implementation of agricultural industrialization management. To implement the industrial management of agriculture and promote the construction of new countryside, governments at all levels should eliminate the institutional barriers, transform governmental functions gradually and prioritize planning, regulation, service and supervision, changing from merely management to playing the role of market mechanism. Meanwhile, economic, legal and administrative means should be properly adopted to advance the industrial management and the healthy improvement of modern agriculture.

Full Text Available Rural development as the notion of development has been strongly influenced by the idea of economic growth. Conversely, the rural development road has been focus on agricultural modernization of production systems, intensive use of chemical inputs to increase levels and technology transfer. The actual rural reality has conducted to a revaluation of what rural means and therefore its development. In these sense has grown the importance of rural related activities linked to the diversification and generating of extra revenues for rural families. This could be one of the cases behind this change in perceptions on previous rural development, giving more importance to other aspects such as cultural diversity, community participation, decision taking, decentralization processes, cultural values, and in consequence hot associate rural development with agricultural development.El desarrollo rural al igual que el sólo desarrollo, ha estado fuertemente influenciado por la idea que lo liga con el crecimiento económico. Concebido de esta forma, la manera como se ha intentado alcanzar desarrollo rural ha sido por medio de la modernización de los sistemas de producción agropecuaria, del uso indiscriminado de insumos químicos para aumentar los niveles productivos y de transferencia de tecnología. La realidad que se vive en el sector rural ha hecho que se evolucione hacia una revaloración de lo que significa lo rural y, de esta manera, también su desarrollo. Por este camino han tomado más importancia actividades conexas a lo productivo agropecuario y también la diversificación de las formas de generación de ingresos para las familias rurales. Ésta podría ser una de las causas para que también cambie la percepción que existía sobre el desarrollo rural y se brinde más importancia a otros aspectos como la aceptación de la diversidad, la participación de la comunidad en la toma de decisiones, la descentralización de la administración, el

Agriculture in developing countries has attracted increasing attention in international negotiations within the United Nations Framework Convention on Climate Change for both adaptation to climate change and greenhouse gas mitigation. However, there is limited understanding about potential complementarity between management practices that promote adaptation and mitigation, and limited basis to account for greenhouse gas emission reductions in this sector. The good news is that the global research community could provide the support needed to address these issues through further research linking adaptation and mitigation. In addition, a small shift in strategy by the Intergovernmental Panel on Climate Change (IPCC) and ongoing assistance from agricultural organizations could produce a framework to move the research and development from concept to reality. In turn, significant progress is possible in the near term providing the basis for UNFCCC negotiations to move beyond discussion to action for the agricultural sector in developing countries.

Since 1980, the number of undernourished people in eastern and southern Africa has more than doubled. Rural development stalled and rural poverty expanded during the 1990s. Population growth remains very high and declining per capita agricultural capacity retards progress towards Millennium Development goals. Analyses of in situ station data and satellite observations of precipitation identify another problematic trend. Main growing season rainfall receipts have diminished by approximately 15% in food insecure countries clustered along the western rim of the Indian Ocean. Occurring during the main growing seasons in poor countries dependent on rain fed agriculture, these declines are societally dangerous. Will they persist or intensify? Tracing moisture deficits upstream to an anthropogenically warming Indian Ocean leads us to conclude that further rainfall declines are likely. We present analyses suggesting that warming in the central Indian Ocean disrupts onshore moisture transports, reducing continental rainfall. Thus late 20th century anthropogenic Indian Ocean warming has probably already produced societally dangerous climate change by creating drought and social disruption in some of the world's most fragile food economies. We quantify the potential impacts of the observed precipitation and agricultural capacity trends by modeling millions of undernourished people as a function of rainfall, population, cultivated area, seed and fertilizer use. Persistence of current tendencies may result in a 50% increase in undernourished people. On the other hand, modest increases in per capita agricultural productivity could more than offset the observed precipitation declines. Investing in agricultural development can help mitigate climate change while decreasing rural poverty and vulnerability.

Stress is one of the main causes of health problems, especially mental disorders. These health problems cause a significant amount of ability loss and increase cost. It is estimated that by 2020, mental disorders will constitute 15% of the total disease burden, and depression will rank second only after ischemic heart disease. Environmental experiences are paramount in increasing the liability of mental disorders in those who constantly face sustained high levels of stress. The objective of this study was to develop a stress scale for seasonal migrant agricultural workers aged 18 years and older. The sample consisted of 270 randomly selected seasonal migrant agricultural workers. The average age of the participants was 33.1 ± 14, and 50.7% were male. The Cronbach alpha coefficient and test-retest methods were used for reliability analyses. Although the factor analysis was performed for the structure validity of the scale, the Kaiser-Meyer-Olkin coefficient and Bartlett test were used to determine the convenience of the data for the factor analysis. In the reliability analyses, the Cronbach alpha coefficient of internal consistency was calculated as .96, and the test-retest reliability coefficient was .81. In the exploratory factor analysis for validity of the scale, four factors were obtained, and the factors represented workplace physical conditions (25.7% of the total variance), workplace psychosocial and economic factors (19.3% of the total variance), workplace health problems (15.2% of the total variance), and school problems (10.1% of the total variance). The four factors explained 70.3% of the total variance. As a result of the expert opinions and analyses, a stress scale with 48 items was developed. The highest score to be obtained from the scale was 144, and the lowest score was 0. The increase in the score indicates the increase in the stress levels. The findings show that the scale is a valid and reliable assessment instrument that can be used in

In developing countries,land productivity involves little market,where the agricultural land use is mainly determined by the food demands as well as the land suitability.The land use pattern will not ensure everywhere enough land for certain cropping if spatial allocation just according to land use suitability.To solve this problem,a subzone and a pre-allocation for each land use are added in spatial allocation module,and land use suitability and area optimization module are incorporated to constitute a whole agricultural land use optimal allocation (ALUOA) system.The system is developed on the platform.Net 2005 using ArcGIS Engine (version 9.2) and C# language,and is tested and validated in Yili watershed of Xinjiang Region on the newly reclaimed area.In the case study,with the help of soil data obtained from 69 points sampled in the fieldwork in 2008,main river data supplied by the Department of Water Resources of Xinjiang Uygur Autonomous Region in China,and temperature data provided by Data Center for Resources and Environmental Sciences,Chinese Academy of Sciences,land use suitability on eight common crops are evaluated one by one using linear weighted summation method in the land use suitability model.The linear programming (LP) model in area optimization model succeeds to give out land area target of each crop under three scenarios.At last,the land use targets are allotted in space both with a six subzone file and without a subzone file.The results show that the land use maps with a subzone not only ensure every part has enough land for every crop,but also gives a more fragmental land use pattern,with about 87.99％ and 135.92％ more patches than the one without,while at the expense of loss between 15.30％ and 19.53％ in the overall suitability at the same time.

Tritium has a complex behaviour once released into the environment. Tritium can be effectively incorporated into biological systems, including the human body, as organically bound tritium (OBT) with a larger residence time than tritiated water (HTO). In the last years robust models were developed for tritium dynamics in mammals (human included), birds and fish but all of them depend on the knowledge of intake for both terrestrial or aquatic food chain. The uncertainty of the present models for tritium in crops following an accidental atmospheric release, is very high and has impacts on the engineering actions for handling and decreasing the nuclear risk. The gaps in knowledge or the local variability of key parameters were recognised as source of uncertainty. Based on an interdisciplinary approach, CROPTRIT model was gradually developed in the last decade focusing on the detecting of the uncertainty sources. Crops of interest depends on each specific case but wheat and rice cover the majority of the practical needs for radiological risk modelling (the major food in Europe and Asia). An analysis of the processes involved in the Soil-Vegetation-Atmosphere Transfer (SVAT) of tritium was done in connection with the available experimental results. The agricultural research is focused on the improving of the yield and the crop growth models were developed in relation with the genotype, weather and management of fertilisation and water. For the radiological purposes, the interest lies in the pollutant concentration at harvest and the CROPTRIT model is focused on the influence of various processes contributing to variability and uncertainty of tritium (OBT and HTO) at harvest. The current results evidentiate the role of the stomatal conductance and difficulties at the day/night transitions, as well as the complex behaviour of the maintenance respiration. A review of the experimental results demonstrates the importance of OBT formation in night conditions and difficulties

Insects that should be considered for conservation attention are often overlooked because of a lack of data. The detailed information necessary to assess population growth, decline, and maximum range is particularly difficult to acquire for rare and cryptic species. Many of these difficulties can be overcome with the use of life table analyses and heat energy accumulation models common in agriculture. The wekiu bug (Nysius wekiuicola), endemic to the summit of one volcanic mountain in Hawaii, is a rare insect living in an environmentally sensitive alpine stone desert, where field-based population assessments would be inefficient or potentially detrimental to natural and cultural resources. We conducted laboratory experiments with the insects by manipulating rearing temperatures of laboratory colonies and made detailed observations of habitat conditions to develop life tables representing population growth parameters and environmental models for wekiu bug phenology and demographic change. Wekiu bugs developed at temperatures only found in its environment on sunny days and required the thermal buffer found on cinder cones for growth and population increase. Wekiu bugs required approximately 3.5 months to complete one generation. The bug developed optimally from 26 to 30 °C, temperatures that are much higher than the air temperature attains in its elevational range. The developmental temperature range of the species confirmed a physiological reason why the wekiu bug is only found on cinder cones. This physiology information can help guide population monitoring and inform habitat restoration and conservation. The wekiu bug was a candidate for listing under the U.S. Endangered Species Act, and the developmental parameters we quantified were used to determine the species would not be listed as endangered or threatened. The use of developmental threshold experiments, life table analyses, and degree day modeling can directly inform otherwise unobservable habitat needs and

Increased groundwater withdrawals from confined aquifers in the Maryland Coastal Plain to supply anticipated growth at Fort George G. Meade (Fort Meade) and surrounding areas resulting from the Department of Defense Base Realignment and Closure Program may have adverse effects in the outcrop or near-outcrop areas. Specifically, increased pumping from the Potomac Group aquifers (principally the Patuxent aquifer) could potentially reduce base flow in small streams below rates necessary for healthy biological functioning. Additionally, water levels may be lowered near, or possibly below, the top of the aquifer within the confined-unconfined transition zone near the outcrop area. A three-dimensional groundwater flow model was created to incorporate and analyze data on water withdrawals, streamflow, and hydraulic head in the region. The model is based on an earlier model developed to assess the effects of future withdrawals from well fields in Anne Arundel County, Maryland and surrounding areas, and includes some of the same features, including model extent, boundary conditions, and vertical discretization (layering). The resolution (horizontal grid discretization) of the earlier model limited its ability to simulate the effects of withdrawals on the outcrop and near-outcrop areas. The model developed for this study included a block-shaped higher-resolution local grid, referred to as the child model, centered on Fort Meade, which was coupled to the coarser-grid parent model using the shared node Local Grid Refinement capability of MODFLOW-LGR. A more detailed stream network was incorporated into the child model. In addition, for part of the transient simulation period, stress periods were reduced in length from 1 year to 3 months, to allow for simulation of the effects of seasonally varying withdrawals and recharge on the groundwater-flow system and simulated streamflow. This required revision of the database on withdrawals and estimation of seasonal variations in

The distribution of man-made organic compounds, specifically gasoline-derived compounds, was investigated from 2004 to 2006 in Lakes Mead and Mohave and one of its tributary streams, Las Vegas Wash. Compounds contained in raw gasoline (benzene, toluene, ethylbenzene, xylenes; also known as BTEX compounds) and those produced during combustion of gasoline (polycyclic aromatic hydrocarbon compounds; also known as PAH compounds) were detected at every site sampled in Lakes Mead and Mohave. Water-quality analyses of samples collected during 2004-06 indicate that motorized watercraft are the major source of these organic compounds to the lakes. Concentrations of BTEX increase as the boating season progresses and decrease to less than detectable levels during the winter when few boats are on the water. Volatilization and microbial degradation most likely are the primary removal mechanisms for BTEX compounds in the lakes. Concentrations of BTEX compounds were highest at sampling points near marinas or popular launching areas. Methyl tert-butyl ether (MTBE) was detected during 2004 but concentrations decreased to less than the detection level during the latter part of the study; most likely due to the removal of MTBE from gasoline purchased in California. Distribution of PAH compounds was similar to that of BTEX compounds, in that, concentrations were highest at popular boating areas and lowest in areas where fewer boats traveled. PAH concentrations were highest at Katherine Landing and North Telephone Cove in Lake Mohave where many personal watercraft with carbureted two-stroke engines ply the waters. Lake-bottom sediment is not a sink for PAH as indicated by the low concentrations detected in sediment samples from both lakes. PAH compounds most likely are removed from the lakes by photochemical degradation. PAH compounds in Las Vegas Wash, which drains the greater Las Vegas metropolitan area, were present in relatively high concentrations in sediment from the upstream

This paper describes the results of a study to determine if crop acreage and biomass estimates could be improved by using visible IR and microwave data. The objectives were to (1) develop and test agricultural crop classification models using two or more spectral regions (visible through microwave), and (2) estimate biomass by including microwave with visible and infrared data. Aircraft multispectral data collected during the study included visible and infrared data (multiband data from 0.5 m - 12 m), and active microwave data K band (2 cm), C band (6 cm), L band (20 cm), and P band (75 cm) HH and HV polarizations. Ground truth data from each field consisted of soil moisture and biomass measurements. Results indicated that C, L, and P band active microwave data combined with visible and infrared data improved crop discrimination and biomass estimates compared to results using only visible and infrared data. The active microwave frequencies were sensitive to different biomass levels; K and C being sensitive to differences at low biomass levels, while P band was sensitive to differences at high biomass levels.

Full Text Available This paper analyzes the impact of foreign economic grocery relations on the state of self-development and self-regulation in the agrarian sector of the country and regions. A definition of the concept of «self-regulation of the agrarian sector in the region» is given. The characteristic of long-term trends in food independence is given. In this regard, the current state of food self-sufficiency in the regions of Russia on essential grocery is analyzed. It is concluded that the majority of regions are characterized by low levels of selfsufficiency in grocery. The main trends of Russian food exports in recent years are shown. The reasons for the sharp growth in grain exports are analyzed. The estimation of the possibilities for further increase of exports of these products in connection with the planned growth of consumption and production of staple food as predicted by the Russian government is made. In general, the authors believe that low levels of food self-sufficiency of the country may be not only at significant food imports, but also at low volumes of imports, coupled with the high volume of agricultural exports. Accordingly, in both cases the possibility of selfdevelopment of the regional agrarian scope is undermined because of the influence of external factors (low levels of food self-sufficiency in the country.
Nitrogen fertilizer accounts for 25 to 33% of the energy requirements in modern crop agriculture in the world today. Energy input for the manufacture of these N fertilizers is in the range of 460 [times] 10[sup 12] Btu per year. Unfortunately, for some N sources up to 70% of this energy in the form of NK can be lost through improper application techniques and poor N management strategies. Anhydrous NH[sub 3] may be lost to the atmosphere during and after placement due to soil conditions placement. Measurement of volatile N is difficult, especially under field conditions. A precise and convenient method of measuring gaseous NH[sub 3] near and above the soil surface is prerequisite to the development and evaluation of altemative fertilizer management strategies and application techniques which can reduce the potential for significant loss. Recent advances in integrated-optic (IO) based sensing offers the potential of measuring low levels of NH[sub 3] loss from a cropping system in the range of 100 ppB. The integrated design of an IO system allows for a more durable device that can be mass produced at low cost. Under Phase I of this project, two IO devices were designed and tested: an absorption device using an oxazine dye as a waveguide coating and an interferometric device using an anilinium salt as a waveguide coating.

Full Text Available This paper presents a mathematical model of economic development of an enterprise with a particular point of assessment of capital-labor and ratio capitalequipment accumulation conditions and their further changes depending on thestrategy of thecompany. To construct a mathematical model of the economy's growth indicators, Solow model which adequately reflects the key aspects of the economy-wide process of expanded reproduction and helps to highlight the main features of the formal models of the dynamics is applied, as well as Shell model with applying Pontryagin maximum principle. An organization's readiness to investment processes — investment «maturity» — is seen through the current level of technical capacity and current capital-labor ratio. The substantiation of the need for a certain level of saturation of agricultural equipment in the organization as a secure mean of ensuring the optimum performance of work in the most intense phase of the production of complex planting and harvesting is provided. To construct a mathematical model reflecting the dependence of capital-labor productivity on capital-labor ratio, a mathematical model in the form of the production function of Cobb-Douglas type is suggested.

Agricultural waste ashes are used as resource materials to synthesize new glass and glass-ceramics. The as-prepared materials are characterized using various techniques for their structural and dielectric properties to check their suitability in microelectronic applications. Sugarcane leaves ash exhibits higher content of alkali metal oxides than rice husk ash, which reduces the melting point of the components due to eutectic reactions. The addition of sugarcane leaves ash in rice husk ash promotes the glass formation. Additionally, it prevents the cristobalite phase formation. These materials are inherently porous, which is responsible for low dielectric permittivity i.e. 9 to 40. The presence of less ordered augite phase enhances the dielectric permittivity as compared to cristobalite and tridymite phases. The present glass-ceramics exhibit lower losses than similar materials synthesized using conventional minerals. The dielectric permittivity is independent to a wide range of temperature and frequency. The glass-ceramics developed with adequately devitrified phases can be used in microelectronic devices and other dielectric applications.
Full Text Available Elaborated during the first half of 2004 as an UNDP-financed project and never published in a complete form before, this study documents the failures of prolonged and significant state interference in the agricultural sector in Romania, focusing on the post-communist period. Given the unavoidable facts that in the absence of private property it is impossible to have either a rational allocation of resources and the right incentives, we reach the conclusion that the failures of the Romanian agriculture were not at all accidental, but inherent in its statist design. An assessment of the European Common Agricultural Policy and its potential impact on our agricultural sector is provided in the last part of the study.
