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

An accelerated life test is described which was developed to predict the life of the 25 kW photovoltaic array installed near Mead, Nebraska. A quantitative model for accelerating testing using multiple environmental stresses was used to develop the test design. The model accounts for the effects of thermal stress by a relation of the Arrhenius form. This relation was then corrected for the effects of nonthermal environmental stresses, such as relative humidity, atmospheric pollutants, and ultraviolet radiation. The correction factors for the nonthermal stresses included temperature-dependent exponents to account for the effects of interactions between thermal and nonthermal stresses on the rate of degradation of power output. The test conditions, measurements, and data analyses for the accelerated tests are presented. Constant-temperature, cyclic-temperature, and UV types of tests are specified, incorporating selected levels of relative humidity and chemical contamination and an imposed forward-bias current and static electric field.

This study examined the hypothesis that exposure to sublethal concentrations of contaminants alters the gonadal condition of feral common carp Cyprinus carpio. Adult common carp in Lake Mead, Nevada, were collected from a contaminated site (Las Vegas Bay) that receives municipal and industrial effluent and from a reference site (Overton Arm) with a relatively low level of contamination. Fish were sampled seven times over a 1-year period extending over two separate spawning seasons. Morphometric and histopathological parameters of gonadal and germ cell development were determined. In males, the pattern of seasonal changes in the gonadosomatic index (GSI) was similar between the sites and showed no clear association with site-specific seasonal temperature profiles. However, Las Vegas Bay males had consistently lower GSI values and, on one of the sampling dates, a lower proportion of sperm relative to other germ cell stages (determined histologically). Further, Las Vegas Bay males had a higher incidence of gonadal macrophage aggregates, which are putative tissue biomarkers of contaminant exposure in fishes. In females, seasonal GSI profiles, the frequency of fish with postovulatory follicles (an index of spawning activity), and the timing of new follicle recruitment all showed differences between sites, but these differences generally matched differences in water temperature profile. Also, the peak size-frequency of full-grown follicles did not differ between sites, and estimates of fecundity for the second spawning season indicated that females from the reference site unexpectedly produced a lower number of gametes, Overall, site differences in gonadal condition were observed in carp of both sexes but they seemed to be associated with site differences in contaminant levels only in males. The apparent lack of association between contaminant level and gonadal condition in female carp from mildly mesotrophic Lake Mead may indicate a lack of contaminant effects in
Full Text Available Mead is a traditional alcoholic beverage obtained by fermenting mead wort; however, its production still remains frequently an empirical exercise. Different meads can be produced, depending on fermentation conditions. Nevertheless, to date few studies have been developed on factors that may influence mead quality. The main objective of this work was to study the influence of sweetness and ethanol content on mead acceptability. Different meads were produced with two sweetness levels (sweet and dry meads and three ethanol contents (18, 20, 22% (v/v, adjusted by brandy addition. Afterwards, meads acceptability was evaluated by sensory analysis through a consumers’ panel (n=108 along with chemical analysis by HPLC-RID of glucose, fructose, ethanol, glycerol and acetic acid. The sweet (75 gglucose+fructose/L and dry (23 gglucose+fructose/L meads presented glycerol contents equal to 5.10±0.54 and 5.96±0.95 g/L, respectively, that were desirable since glycerol improves mead quality. Low concentrations of acetic acid were determined (0.46±0.08 and 0.57±0.09 g/L, avoiding the vinegar off-character. Concerning sensory analysis, the alcohol content of mead had no effect on the sensory attributes studied, namely, aroma, sweetness, flavour, alcohol feeling and general appreciation. Regarding sweetness, the “sweet meads” were the most appreciated by the consumers (score of 5.4±2.56, whereas the “dry meads” (score of 2.7±2.23 showed low acceptability. In conclusion, this work revealed that sweetness is a sensory key attribute for mead acceptance by the consumers, whereas ethanol content (18 to 22% (v/v is not.

This paper introduced the concepts of organic agriculture as defined by different international organizations, origin and theoretical development of organic agriculture, as well as its developing trajectory in China (i.e. a late start followed by rapid growth compared to developed countries). The differences between domestic and international organic agriculture were illustrated by scale, crop types, production standards, inputs and planting techniques. Constraints limiting improvements to organic agriculture in aspects of standards, technology, marketing, certification, environmental pollution, enterprise reputation, and national policies were discussed. Future directions and strategies for developing healthy organic agriculture in China were provided.

A long-range program is needed to maximize and sustain world food production without destroying its ecological base. Attempts to make more land available for cultivation and to increase crop yields must incorporate environmental planning as well. The most-pressing agricultural problems are soil loss because of environmental degradation, erosion, runoff, and urbanization. The large-scale use of pesticides, whose inefficient application leaves residues in food and leads to new resistant species, and irrigration projects, which lead to salination and alkalinization of groundwater and the spread of water-borne diseases, as well as other problems are dealt with best by using strategies that work with nature and natural systems.

The world's demand for food is expected to double within the next 50 years, while the natural resources that sustain agriculture will become increasingly scarce, degraded, and vulnerable to the effects of climate change. In many poor countries, agriculture accounts for at least 40 percent of GDP and 80 percent of employment. At the same time, about 70 percent of the world's poor live in rural areas and most depend on agriculture for their livelihoods. World Development Report 2008 seeks t...

Mead is a traditional drink, which results from the alcoholic fermentation of diluted honey carried out by yeasts. However, when it is produced in a homemade way, mead producers find several problems, namely, the lack of uniformity in the final product, delayed and arrested fermentations, and the production of "off-flavours" by the yeasts. These problems are usually associated with the inability of yeast strains to respond and adapt to unfavourable and stressful growth conditions. The main objectives of this work were to evaluate the capacity of Saccharomyces cerevisiae strains, isolated from honey of the Trás-os-Montes (Northeast Portugal), to produce mead. Five strains from honey, as well as one laboratory strain and one commercial wine strain, were evaluated in terms of their fermentation performance under ethanol, sulphur dioxide and osmotic stress. All the strains showed similar behaviour in these conditions. Two yeasts strains isolated from honey and the commercial wine strain were further tested for mead production, using two different honey (a dark and a light honey), enriched with two supplements (one commercial and one developed by the research team), as fermentation media. The results obtained in this work show that S. cerevisiae strains isolated from honey, are appropriate for mead production. However it is of extreme importance to take into account the characteristics of the honey, and supplements used in the fermentation medium formulation, in order to achieve the best results in mead production.
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 As a result of a sustained drought in the Southwestern United States, and in order to maintain existing water capacity in the Las Vegas Valley, the Southern Nevada Water Authority constructed a new deep-water intake (Intake No. 3 located in Lake Mead. The project included a 185 m deep shaft, 4.7 km tunnel under very difficult geological conditions, and marine works for a submerged intake. This paper presents the experience that was gained during the design and construction and the innovative solutions that were developed to handle the difficult conditions that were encountered during tunneling with a dual-mode slurry tunnel-boring machine (TBM in up to 15 bar (1 bar = 105 Pa pressure. Specific attention is given to the main challenges that were overcome during the TBM excavation, which included the mode of operation, face support pressures, pre-excavation grouting, and maintenance; to the construction of the intake, which involved deep underwater shaft excavation with blasting using shaped charges; to the construction of the innovative over 1200 t concrete-and-steel intake structure; to the placement of the intake structure in the underwater shaft; and to the docking and connection to an intake tunnel excavated by hybrid TBM.

The genetic technologies being adopted in South Asia are significant factors in the agricultural development of the area. But, labeling them " miracle seeds," solely responsible for recent agricultural growth, is misleading. Certainly the introduction of new genetic technology has catalyzed South Asian agriculture and has instilled a new dynamism essential to economic development. Somewhat similar phenomena have, however, been observed in other parts of the world in other periods of history. The nature of these genetic technologies, how they are being applied, and their limits and potential have been explored above. Also, the effects of these varieties on the generation of employment, and the distribution of benefits accruing from them have been examined in preliminary fashion. Stemming from the preceding discussion, two areas of priority appear obvious. First, the close association of genetic technologies with irrigation suggests that irrigation should receive more attention than it has in the past. Large-scale public irrigation schemes are expensive and have tended to yield low rates of return. However, there appears to be room for marginal increases in, or improvements of, existing irrigation facilities. Second, even with a rapid spread of the practices associated with highyeild varieties, it may be too much to expect the farm sector to absorb the expected increases in the rural labor force. The generation of employment is a major problem in India as well as in most other developing countries. Hence, possibilities for expanding rural, nonfarm employment and controlling population growth should be sought vigorously.

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

The coastal seas are one of the most valuable resources on the planet but they are threatened by human activity. We rely on the coastal area for mineral resources, waste disposal, fisheries and recreation. In Europe, high population densities and high levels of industrial activity mean that the pressures arising from these activities are particularly acute. One of the main problems concerning coastal seas is the rapid increase in the amounts of nitrogen-based pollutants entering the water. They come from many sources, the most important ones being traffic, industry and agriculture. These pollutants can be used by algae as nutrients. The increasing concentrations of these nutrients have led to excessive growth of algae, some of which are harmful. When algae die and decay, oxygen in the water is used up and the resulting lower levels of oxygen may lead to fish kills. Human activity has probably doubled the amount of chemically and biologically reactive nitrogen present globally. In Europe the increases have been greater than this, leading to real concern over the health of coastal waters. Rivers have, until recently, been thought to be the most important source of reactive nitrogen to the coastal seas but we now know that inputs from the atmosphere are large and can equal, or exceed, those from the rivers. Our initial hypothesis was that atmospheric inputs are important and potentially different in their effect on coastal ecosystems to riverine inputs and hence require different management strategies. However, we had almost no information on the direct effects of atmospheric deposition on marine ecosystems, though clearly such a large external nitrogen input should lead to enhanced phytoplankton growth The aim of this European Union funded MEAD project has been to determine how inputs of nitrogen from the atmosphere affect the chemistry and biology of coastal waters. To try to answer this, we have conducted field experiments in the Kattegat, an area where we know

Full Text Available Population growth in the context of limited land resources makes the global scientific society research new ways to increase the agricultural yields. Over the past 20 years, biotechnology and GM crops have become widely spread and now are cultivated in 28 countries. The total area of crops has tripled, and it suggests the further vertical and horizontal integration in short term. In 2015, the US Department of Agriculture authorized the commercial use of GM farm animals. The development of agricultural biotechnology market is constrained by opponents of GM crops in more than 160 countries, which include Russia and the European Union, where the production of GM crops is banned due to economic, ethical, ideological and biological reasons. Currently, the EU is seeking to reduce the imports of GM crops and products; Russia's GM imports and exports are prohibited, and the deadline of designing a consolidated position on agricultural biotechnology has been moved to 2017. The author seeks to analyze the volume of production and international trade of agricultural products based on biotechnologies and to describe the main trends in the global market, which could be integrated into the food value chain in Russia. In the context of the worsening economic indicators, the article proposes the possibility of extending the use of GM crops in Russia non-food sector.

The effects of mead wort heat treatment on the mead fermentation process and antioxidant activity were tested. The experiment was conducted with the use of two different honeys (multiflorous and honeydew) collected from the Lower Silesia region (Poland). Heat treatment was performed with the use of a traditional technique (gently boiling), the more commonly used pasteurization, and without heat treatment (control). During the experiment fermentation dynamics were monitored using high performance liquid chromatography with refractive index detection (HPLC-RID). Total antioxidant capacity (TAC) and total phenolic content (TPC) were estimated for worts and meads using UV/Vis spectrophotometric analysis. The formation of 5-hydroxymethylfurfural (HMF) was monitored by HPLC analyses. Heat treatment had a great impact on the final antioxidant capacity of meads.
The article explicates George Herbert Mead's theory of consciousness as presented in Mind, Self and Society. According to Mead, the term consciousness may refer to three different sets of phenomena: (1) the environment as implied by our goal-directed action; Mead names this consciousness aspect...... experience; it is shared by humans and subhuman animals alike; (2) consciousness of environmental experience; Mead names this consciousness aspect awareness; it is exclusively human; (3) the peculiar sensed qualities attaching to consciousness, equalling what is today named qualia. Descartes......-inspired psychology makes the third consciousness aspect all-important. Within Mead's framework for a darwinistically inspired psycholgy, it becomes theoretically insignificant....

Future agricultural and rural development is, to a large extent, influenced by the projected food needs of 2.5 billion people expected to swell the world population by 2020. This increase will require more food in general and, in view of recent experience in East Asia, more animal products. To achieve this increase will require judicious use of resources, and trade, especially in those countries where natural resources are insufficient to support food production. Achieving food sufficiency in a sustainable manner is a major challenge for farmers, agro-industries, researchers and governments. The latter play an important role as many of the farmers' choices are, to a large extent, directed by government or supra-government, often through macro- and micro-economic policy. In many countries the economic, environmental, trade and agricultural policies have not been conducive to an agricultural development that is risk-free with respect to the environment, animal welfare or public health. The recent decline of government support in agriculture forced farmers in Western countries to think about more risk adverse agricultural practices and more efficient production systems. On the other hand, many countries in Eastern Europe and the former Soviet Union, as well as other developing countries, are still going through a painful process of adjustment to new market conditions. International banks and development agencies have a mandate to help developing countries, but are somewhat restricted both by needing to work directly with governments and by their perceived dogmatic approach to development. Changing policies do, now and in the future, also affect the development of animal disease control programmes, including the control of parasitic diseases. On the one hand there is an increasing interest in risk-free control practices, and on the other hand a demand for greater regulatory control over the production process. As parasitic diseases of animals are closely linked to the

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

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

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".

Agriculture plays an important role in the national economy of Pakistan, where most of the rapidly increasing population resides in rural areas and depends on agriculture for subsistence. Biotechnology has considerable potential for promoting the efficiency of crop improvement, food production, and poverty reduction. Use of modern biotechnology started in Pakistan since 1985. Currently, there are 29 biotech centers/institutes in the country. However, few centers have appropriate physical facilities and trained manpower to develop genetically modified (GM) crops. Most of the activities have been on rice and cotton, which are among the top 5 crops of Pakistan. Biotic (virus/bacterial/insect) and abiotic (salt) resistant and quality (male sterility) genes have already been incorporated in some crop plants. Despite acquiring capacity to produce transgenic plants, no GM crops, either produced locally or imported, have been released in the country. Pakistan is signatory to the World Trade Organization, Convention on Biological Diversity, and Cartagena protocols. Several legislations under the Agreement on Trade-Related Aspects of Intellectual Property Rights have been promulgated in the country. National Biosafety Guidelines have been promulgated in April 2005. The Plant Breeders Rights Act, Amendment in Seed Act-1976, and Geographical Indication for Goods are still passing through discussion, evaluation, and analysis phases. Meanwhile, an illegal GM crop (cotton) has already sneaked into farmer's field. Concerted and coordinated efforts are needed among various ministries for implementation of regulation and capacity building for import/export and local handling of GM crops. Pakistan could easily benefit from the experience of Asian countries, especially China and India, where conditions are similar and the agriculture sector is almost like that of Pakistan. Thus, the exchange of information and experiences is important among these nations.

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. Copyright 2006 Wiley Periodicals, Inc.

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.

Full Text Available In the present article, an attempt was made to assess the sustainability of agricultural holdings with diff erent directions of production. 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

Full Text Available Indian agriculture sector is a significant emitter of Green House Gas (GHG, which is projected to increase by 47% between 2011 and 2020. In response to this, India has committed itself to voluntarily reduce its emissions intensity (emissions per unit GDP between 20 to 25 percent below 2005 levels by 2020. This would require rapid and significant scaling up of mitigation efforts including the agriculture sector, which remains a challenge, as mitigation is not a priority in Indian agriculture. The study found out that in-spite of numerous mitigation technologies that are readily available for takeoff, the scale of adoption and deployment is far from sufficient to meet the emission targets set by the Government of India, mainly due to lack of financial incentives, capacity building of farmers, and an enabling policy at different levels. This study identified a suite of feasible interventions for promoting low carbon agriculture such as: low tillage systems as it has negative costs due to savings on tillage and fuel; introduction of superior livestock breeds to reduce numbers (especially unproductive cattle and increase yield; use of livestock wastes to produce energy for cooking and heating through bio-gas technology can not only reduce methane emission but also save electricity costs for the households and; introduction of carbon credits and exploration of domestic carbon markets. An enabling policy environment must be created for these interventions to take off.

Given the importance of the availability and quality of water in Lake Mead, it has become one of the most intensely sampled and studied bodies of water in the United States. As a result, data are available from sampling stations across the lake (fig. 4-1 and see U.S. Geological Survey Automated Water-Quality Platforms) to provide information on past and current (2012) water-quality conditions and on invasive species that influence—and are affected by—water quality. Water quality in Lakes Mead and Mohave generally exceeds standards set by the State of Nevada to protect water supplies for public uses: drinking water, aquatic ecosystem health, recreation, or agricultural irrigation. In comparison to other reservoirs studied by the U.S. Environmental Protection Agency (USEPA) for a national lake assessment (U.S. Environmental Protection Agency, 2010), Lake Mead is well within the highest or ‘good’ category for recreation and aquatic health (see U.S. Environmental Protection Agency National Lakes Assessment and Lake Mead for more details). While a small part of the lake, particularly Las Vegas Bay, is locally influenced by runoff from urbanized tributaries such as Las Vegas Wash, contaminant loading in the lake as a whole is low compared to other reservoirs in the nation, which are influenced by runoff from more heavily urbanized watersheds (Rosen and Van Metre, 2010).

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.

Full Text Available The paper is focused on the evaluation of economic, social and environmental challenges of sustainable agriculture. The selected indicators of the economic challenges of sustainable agriculture imply that agriculture in Slovakia is not in long term be able to ensure competitiveness in the European market, gross agricultural output is characterized by a faster decline in animal production than in crop production and the value of import of agri-food commodities is higher than the value of export. According to selected indicators of social challenges of sustainable agriculture the number of persons working in agriculture has decreasing tendency in last years. The evaluation of selected indicators of environmental challenges of sustainable agriculture implies that area of organic agriculture is the most widely applied sub-measure within the measure agri-environmental payments. For ensuring the balance of the three mentioned dimensions of sustainable agriculture is necessary to increase of local production and consumption of local products, to ensure the protection of nature and landscape, to ensure rural development and to increase the employment opportunities in countryside.

We have analyzed high-resolution Magellan Doppler tracking data over Mead crater, using both line-of-sight and spherical harmonic methods, and have found a negative gravity anomaly of about 4-5 mgal (at spacecraft altitude, 182 km). This is consistent with no isostatic compensation of the present topography; the uncertainty in the analysis allows perhaps as much as 30% compensation at shallow dpeths (approximately 25 km). This is similar to observations of large craters on Earth, which are not generally compensated, but contrasts with at least some lunar basins which are inferred to have large Moho uplifts and corresponding positive Bouguer anomalies. An uncompensated load of this size requires a lithosphere with an effective elastic lithosphere thickness greater than 30 km. In order for the crust-mantle boundary not to have participated in the deformation associated with the collapse of the transient cavity during the creation of the crater, the yield strength near the top of the mantle must have been significantly higher on Earth and Venus than on the Moon at the time of basin formation. This might be due to increased strength against frictional sliding at the higher confining pressures within the larger planets. Alternatively, the thinner crusts of Earth and Venus compared to that of the Moon may result in higher creep strength of the upper mantle at shallower depths.
Development of road network is one of the strongest drivers of habitat fragmentation. It interferes with ecological processes that are based on material and energy flows between landscape patches. Therefore, changes in temporal patterns of roads may be regarded as important landscape-level environmental indicators. The aim of this study is to analyze road development and associated agricultural land use change near the town of Erdemli located in the eastern Mediterranean coast of Turkey. The study area has witnessed an unprecedented development of agriculture since the 2000s. This process has resulted with the expansion of the road network. Associations between agricultural expansion and road development were investigated. High-resolution satellite images of 2004 and 2015 were used to analyze spatial and temporal dimensions of change. Satellite images were classified using a binary approach, in which land areas were labeled as either "agriculture" or "non-agriculture." Road networks were digitized manually. The study area was divided into 23 sublandscapes using a regular grid with 1-km cell spacing. Percentage of landscape (PL) for agriculture and road density (RD) metrics were calculated for the earlier (2004) and later (2015) years. Metric calculations were performed separately for each of the 23 sublandscapes in order to understand spatial diversity of agriculture and road density. Study results showed that both RD and PL exhibited similar increasing trends between 2004 and 2015.

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

"The untested premise of trade liberalizing U.S. development programs such as the Caribbean Basin Initiative is that commodity trade can substitute for international labor migration. Analysis of U.S. tomato producing regions in Sinaloa, Mexico and Florida suggests that the effect of trade liberalization on international labor migration is uncertain." The emphasis is on how such development projects might affect the flow of illegal migrants to the United States. excerpt

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.

The turn towards nonhuman animals within sociology has shed a critical light on George Herbert Mead, his apparent prioritisation of language and the anthropocentric focus of Symbolic Interactionism (SI). Although Herbert Blumer canonised Mead as the founder of this perspective he also played a key role in excising the evolutionary and 'more-than-human' components in Mead's work. This intervention not only misrepresented Mead's intellectual project, it also made symbols the predominant concern...

Full Text Available The Islamic finance industry is one of the fastest growing industries in the world. However, many potential Muslim customers, particularly in rural areas, have unfulfilled banking needs and lack access to financing. Meanwhile, entrepreneurial projects in the agricultural sector are presumed to optimize economic growth. In addition, some scholars have expounded that the financial problems faced by the agricultural sector are caused by the risks of debt financing and lack of access to the capital market. In Islamic law, almuzara’ah and al-musaqah can be considered as forms of partnership contract in farming. Therefore, using descriptive analysis, this paper attempts to portray how Islamic financial principles are closely related to the agricultural sector in developing Islamic agricultural finance. This study found that the application of the modes of Islamic financing in the agricultural sector through financial institutions could be very effective in providing financing to ensure that the partnership progresses effectively and efficiently. As a result, there is an urgent need to develop a sound agricultural financial system based on Islamic contracts in order to increase and sustain the income of farmers and landowners and to reduce poverty.

Despite significantly contributing to country's overall economic development through providing employment for the people and supplying raw materials for agro- and resource based industrial development, agriculture is putting serious burden on the environment in the process of production and consumption of agricultural produce. It is the largest consumer and polluter of water resources and contributor of atmospheric pollution, land degradation and forest reduction. Agriculture-environmental relationship is complex and the relationship depends on the spatial and biophysical factors and country's level of economic development. This paper tried to document the linkages between agricultural practices and policies with environment. The channels, through which agriculture impacts the environment, is discussed. It is seen that multilateral trade liberalization in agriculture interacts with the domestic agricultural policy reforms to determine the environmental impacts of agriculture. It is seen that agricultural policy reforms and agricultural trade liberalization can have separate environmental effects in the developed and developing countries. A wide range of theoretical and empirical literatures are reviewed, in this paper, to understand the concepts, linkages and environmental problems. Finally, this paper ends up with the conclusion that integrating environmental considerations into domestic agricultural policies and implementing agro-environmental programmes may ensure the decline of environmental problems of agriculture in both the developed and developing countries.

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.

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

Organic agriculture is the highest environmentally valuable agricultural system, and has strategic importance at national level that goes beyond the interests of agricultural sector. In this paper we address development of organic farming simulation model based on a system dynamics methodology (SD). The system incorporates relevant variables, which affect the development of the organic farming. The group decision support system (GDSS) was used in order to identify most relevant variables for construction of causal loop diagram and further model development. The model seeks answers to strategic questions related to the level of organically utilized area, levels of production and crop selection in a long term dynamic context and will be used for simulation of different policy scenarios for organic farming and their impact on economic and environmental parameters of organic production at an aggregate level.

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.

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

In the 1980s the Common Agricultural Policy (CAP) resulted in large surpluses of main agricultural products; dealing with these surpluses consumed large parts of the Commission's and Member States' budgets. To alleviate this problem, a proposal for alternative land use is presented here: large-scale exploitation of biomass for industrial and energy uses, at the level of 600 to 800 million tonnes of oil equivalent a year. The important benefits to arise from this activity will include: job creation in rural districts, solutions to environmental problems, and technologies applicable in developing countries. (author)

The development status and existing problems in the field of nuclear agricultural sciences (NAS) are reviewed. Including the application of nuclear technology in mutation breeding by irradiation, isotopic technique application, food irradiation and sterile insect technique, etc. China has made great achievements in the research and application of nuclear technique in agriculture from 1950s to 1990s. Due to lack of enough financial support to the basic research and reformation of science and research system in China, the development of NAS now meets its tough time. Through analyzing the difference and reasons of NAS development between China and the USA, it is recognized that the innovation in research and scientific system is important for promoting the development speed and research level of NAS.

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

In this study my aim is to clarify George H. Mead’s (1863–1931) impact history and his significance for the development of social psychology. Another task is to systematically analyse the problems and paradoxes faced by Mead in his theory of meaning and concept of the human being. The third target is to draw a holistic theory of human being for the needs of present social psychology and the theory of agency. My approach is philosophical and epistemological, and my method is hermeneutical,...
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.

Highlights: • Multi-effect adsorption desalination (MEAD) cycle for improved performance. • Passive heating of saline water recovering kinetic energy from desorption. • All effects operate at low temperature i.e., below 35 °C unlike conventional cycle. • High PR (6.3) with low temperature heat source. • Analyzed using p–T–q diagram tracking the temperatures and uptakes. - Abstract: 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 1.0 m"3/h tonne of silica gel, 6.3 and 5.1, respectively.

This cross-sectional study examined perceived level of importance, perceived level of competency in extension core competencies, and whether and how perceptions of competency vary by respondents' demographics; ascertained gaps in competency, if any; and identified ways for agricultural development professionals in Cambodia to acquire core competencies. Data were collected using a group-administered survey among 39 agricultural development professionals participating in a national workshop in December 2015. The survey consisted of 48 competencies representing eight core competencies, and each competency had level of importance and level of competency parts. The findings show that extension workers in Cambodia deemed all competencies highly or very highly important to their extension work; however, their perceived level of competency in those competencies appeared not to meet the expectations. The level of competency in all but communication skills and diversity significantly differed by gender but not by age and experience. Respondents indicated all four methods-preservice, in-service, basic induction training, and participation in seminars, workshops, and webinars-equally appropriate to acquire core competencies. The findings imply that the agricultural development authority in Cambodia should review, update, or design extension education curricula incorporating the competencies highlighted in this study and train its extension cadres on those competencies.

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.

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

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.

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.

HOW DO YOU create a new self? However he may phrase this question, it is a central theoretical and practical concern of the therapist every time he confronts a client who comes to him for help. What are the processes out of which the human self emerges? However he may phrase the question, it is a central concern of the social psychologist. The obvious convergence of interests indicated by these two questions should occasion no surprise among students of Sullivan and Mead. What perhaps should be surprising is that an effective synthesis of their theories has progressed no further than it has to date. My remarks today are based on the conviction that a more adequate psychiatric theory and practice and a more complete social psychological theory and research program depend on such a synthesis. Behavioral scientists concerned with the development of a truly interactionist social psychology are, I believe, generally agreed that George Herbert Mead (1863-1931), philosopher and social psychologist, and Harry Stack Sullivan (1892-1949), psychiatrist and social psychologist, have laid conceptual foundations upon which such a discipline can be erected. Now a vast assortment of activities is tagged as social psychology and its boundaries are, indeed, difficult to draw. However, for our present purposes we can define its focus as the study of the processes and products of inter- and intrapersonal and inter- and intragoup interaction, let the boundaries fall where they will.
The Government of Kenya has successfully developed macroeconomic policies that overcome constraints in the domestic and international environments and have a relatively well-functioning public sector. At present, the major challenge facing Kenya concerns the ability of the government to improve agricultural productivity given the weakness of its research services and peasant resistance to development. The response to the 1984 drought indicates that the Government of Kenya has the formal structures in place to deal with emergencies, yet the absence of reliable statistics on grain production, marketing, and on-farm storage led to serious miscalculations of the severity of the drought. Government of Kenya has been reluctant to experiment with institutional forms that reduce the opportunity for direct political control, especially over agricultural marketing. Privatization of the grain trade or the establishment of cooperatively owned local dairies has been proposed but rejected as too risky. New policies and concerted action, at both the government and community levels, tend to be in response to threat or hardship rather than a result of a dynamic strategy. Given this tendency to avoid experimentation with alternative political forms, socioeconomic development in Kenya may be limited in the years ahead.

Despite great recent progress, hunger and poverty remain widespread and agriculturally driven environmental damage is widely prevalent. The idea of agricultural sustainability centers on the need to develop technologies and practices that do not have adverse effects on environmental goods and services, and that lead to improvements in food productivity. Here we show the extent to which 286 recent interventions in 57 poor countries covering 37 M ha (3% of the cultivated area in developing countries) have increased productivity on 12.6 M farms while improving the supply of critical environmental services. The average crop yield increase was 79% (geometric mean 64%). All crops showed water use efficiency gains, with the highest improvement in rainfed crops. Potential carbon sequestered amounted to an average of 0.35 t C ha(-1) y(-1). If a quarter of the total area under these farming systems adopted sustainability enhancing practices, we estimate global sequestration could be 0.1 Gt C y(-1). Of projects with pesticide data, 77% resulted in a decline in pesticide use by 71% while yields grew by 42%. Although it is uncertain whether these approaches can meet future food needs, there are grounds for cautious optimism, particularly as poor farm households benefit more from their adoption.

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.

Freshwater comprises about a mere 2·5% of total global water, of which approximately two-thirds is locked into glaciers at the polar ice caps and on mountains. In conjunction with this, in many instances irrigation with freshwater causes an increase in soil salinity due to overirrigation of agricultural land, inefficient water use and poor drainage of unsuitable soils. The problem of salinity was recognized a long time ago and, due to the importance of irrigated agriculture, numerous efforts have been devoted towards improving crop species for better utilization of saline soils and water. Irrigating plants with saline water is a challenge for practitioners and researchers throughout the world. Recruiting wild halophytes with economic potential was suggested several decades ago as a way to reduce the damage caused by salinization of soil and water. A range of cultivation systems for the utilization of halophytes have been developed, for the production of biofuel, purification of saline effluent in constructed wetlands, landscaping, cultivation of gourmet vegetables, and more. This review critically analyses past and present halophyte-based production systems in the context of genetics, physiology, agrotechnical issues and product value. There are still difficulties that need to be overcome, such as direct germination in saline conditions or genotype selection. However, more and more research is being directed not only towards determining salt tolerance of halophytes, but also to the improvement of agricultural traits for long-term progress. © The Author 2014.

Full Text Available California's Mediterranean agro-ecosystems are a major source of U.S. fruits and vegetables, and vulnerable to future extremes of precipitation and temperature brought on by climate change, including increased drought and flooding, and more intense and longer heat waves. To develop resilience to these threats, strategies are necessary for climate-smart management of soil and water. Long-term, large-scale, replicated ecological experiments provide unique testbeds for studying such questions. At the UC Davis Russell Ranch Sustainable Agriculture Facility (RRSAF, the 100-year Century Experiment, initiated in 1992, is investigating the effects of multiple farming practices in a farm-scale replicated study of 10 row crop cropping systems. It includes different fertility management systems: organic, conventional and hybrid (conventional plus winter cover crop systems; different crops: wheat, tomatoes, corn, alfalfa, cover crops and grasslands; and different irrigation systems: rainfed, flood irrigated and drip irrigated. We briefly describe and report on a selection of long-term experiments conducted at RRSAF investigating soil management and irrigation practices, which are an important focus for developing climate-smart strategies in Mediterranean systems. For example, long-term monitoring of soil carbon content revealed that most crop systems have experienced a small increase in soil carbon since 1993, and increases in organically managed plots were substantially higher. As RRSAF continues to build upon this rich dataset from one of a very few long-term row crop experiments in Mediterranean ecosystems, it provides a testbed for identifying climate-smart solutions for these agronomically important ecosystems.

The goal of this study is to develop an agriculture planning model in order to sustain the future water use under the estimation of crop water requirement, water availability and future climate projection. For this purpose, the Citarum river basin which is located in West Java - Indonesia is selected as the study area. Two emission scenarios A2 and B2 were selected. For the crop water requirement estimation, the output of HadCM3 AOGCM is statistically downscale using SDSM and used as the input for WEAP model developed by SEI (Stockholm Environmental Institute). The reliability of water uses is assessed by comparing the irrigation water demand and the water allocation for the irrigation area. The water supply resources are assessed using the water planning tool. This study shows that temperature and precipitation over the study area are projected to increase in the future. The water availability was projected to increase under both A2 and B2 emission scenarios in the future. The irrigation water requirement is expected to decrease in the future under A2 and B2 scenarios. By comparing the irrigation water demand and water allocation for irrigation, the reliability of agriculture water use is expected to change in the period of 2050s and 2080s while the reliability will not change in 2020s. The reliability under A2 scenario is expected to be higher than B2 scenario. The combination of WEAP and SDSM is significance to use in assessing and allocating the water resources in the region.

This paper estimates the role of agronomic inputs in cereal yield improvements and the consequences for countries' processes of structural change. The results suggest a clear role for fertilizer, modern seeds and water in boosting yields. We then test for respective empirical links between agricultural yields and economic growth, labor share in agriculture and non-agricultural value added per worker. The identification strategy includes a novel instrumental variable that exploits the unique economic geography of fertilizer production and transport costs to countries' agricultural heartlands. We estimate that a half ton increase in staple yields generates a 14 to 19 percent higher GDP per capita and a 4.6 to 5.6 percentage point lower labor share in agriculture five years later. The results suggest a strong role for agricultural productivity as a driver of structural change.

Lake Mead National Recreational Area (LMNRA) serves as critical habitat for several federally listed species and supplies water for municipal, domestic, and agricultural use in the Southwestern U.S. Contaminant sources and concentrations vary among the sub-basins within LMNRA. To investigate whether exposure to environmental contaminants is associated with alterations in male common carp (Cyprinus carpio) gamete quality and endocrine- and reproductive parameters, data were collected among sub-basins over 7 years (1999–2006). Endpoints included sperm quality parameters of motility, viability, mitochondrial membrane potential, count, morphology, and DNA fragmentation; plasma components were vitellogenin (VTG), 17ß-estradiol, 11-keto-testosterone, triiodothyronine, and thyroxine. Fish condition factor, gonadosomatic index, and gonadal histology parameters were also measured. Diminished biomarker effects were noted in 2006, and sub-basin differences were indicated by the irregular occurrences of contaminants and by several associations between chemicals (e.g., polychlorinated biphenyls, hexachlorobenzene, galaxolide, and methyl triclosan) and biomarkers (e.g., plasma thyroxine, sperm motility and DNA fragmentation). By 2006, sex steroid hormone and VTG levels decreased with subsequent reduced endocrine disrupting effects. The sperm quality bioassays developed and applied with carp complemented endocrine and reproductive data, and can be adapted for use with other species.

In order to eradicate hunger in the world agricultural decisions must be made that will design a new model of agricultural production that will be more productive and will fit better in the fight against global warming. These decisions will help to regulate agricultural activities so that they help in the above mentioned fight as well. This new model of agricultural production will come together with the adoption of rural development decisions which will then be suitable for every ecosystem, ...
Full Text Available Lack of capital has been identified as one of the constraints that faced by small scale farmers. The aim of this research was to examine the effect of agricultural credit on the agriculture production, and calculate the inputs and outputs among small scale farmers. Structured questionnaires were distributed to 136 farmers, who had been selected using the stratified random sampling technique, and the data obtained were summarized into percentages. Regression analysis was adopted to assess the impacts of socio-economic factors on loan size among farmers, while Cobb-Douglas Production Function Analysis (CDPFA was used to test the relationship between key independent variables such as loan amount, farm size, inputs and farm output as dependent variable. The analysis revealed a significantly high value of coefficient of determination (R2= 0.922 that reflected a high relationship between the dependent variable and the independent variables; gender, age, education, family size, farm size, farming experience. The Adjusted (R2 coefficient (R2 = 0.918 revealed that 91.8 % of variation in loam size explained by the changes in variables. The results showed a significance in F-test in size of loan. The hypothesis two, exhibited that the independent variables; loan size, farm size, and inputs explained the variation in the total value of farmers output. The study therefore showed that to achieve the positive agricultural credit impacts on agricultural production, The Government and the private sector should regularly and timely facilitate the credit to the small scale farmers.

A photo of a terrestrial or celestial globe can be handled as a map. The only hard issue is its projection: the so-called Tilted Perspective Projection which, if the optical axis of the photo intersects the globe's centre, is simplified to the Vertical Near-Side Perspective Projection. When georeferencing such a photo, the exact parameters of the projections are also needed. These parameters depend on the position of the viewpoint of the camera. Several hundreds of globe photos had to be georeferenced during the Virtual Globes Museum project, which made necessary to automatize the calculation of the projection parameters. The author developed a program for this task which uses the Nelder-Mead Method in order to find the optimum parameters when a set of control points are given as input. The Nelder-Mead method is a numerical algorithm for minimizing a function in a many-dimensional space. The function in the present application is the average error of the control points calculated from the actual values of parameters. The parameters are the geographical coordinates of the projection centre, the image coordinates of the same point, the rotation of the projection, the height of the perspective point and the scale of the photo (calculated in pixels/km). The program reads the Global Mappers Ground Control Point (.GCP) file format as input and creates projection description files (.PRJ) for the same software. The initial values of the geographical coordinates of the projection centre are calculated as the average of the control points, while the other parameters are set to experimental values which represent the most common circumstances of taking a globe photograph. The algorithm runs until the change of the parameters sinks below a pre-defined limit. The minimum search can be refined by using the previous result parameter set as new initial values. This paper introduces the calculation mechanism and examples of the usage. Other possible other usages of the method are
Full Text Available The economic development in Yugoslavia (Serbia after the second world war has been conducted at the expense of agriculture because the industrialisation was in the forefront of the economic policy. It has an impact on the present position of the agriculture compared to the other sectors because the parity of product exchange is still retained at the expense of agriculture. Even under these circumstances agriculture is an industry with a positive foreign trade balance, important share in the national product and the unemployment rate reduction, and that has been analysed and shown in this paper. Many developed European countries are an example of the successful agricultural development as a carrier of the complete development. There are indisputably much wider possibilities for agriculture development in Serbia, and it could become a great comparative advantage of our economy in the developed markets in the world, with the appropriate macroeconomic policy.
For George Herbert Mead, thinking amounts to holding an "inner conversation of gestures ". Such a conception does not seem especially original at first glance. What makes it truly original is the "social-behavioral" approach of which it is a part, and, particularly, two ideas. The first is that the conversation in question is a conversation of gestures or attitudes, and the second, that thought and reflexive intelligence arise from the internalization of an external process supported by the social mechanism of communication: that of conduct organization. It imports then to understand what distinguishes such ideas from those of the founder of behavioral psychology, John B. Watson, for whom thinking amounts to nothing other than subvocal speech.
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 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 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
Full Text Available Sustainability of agricultural production in the world is in serious crisis. Interdependence of agricultural production and the environment is multiple and causality works both ways. On one hand, there are environmental changes which hamper food production, and on the other, the agricultural production, as it is, is severely damaging the environment. The very systems of agricultural production jeopardize future production. The goal of this paper is to explore causes of limitations of sustainable agricultural development in the world, where the authors emphasize the following: gas emissions with greenhouse effect, a disturbed cycle of nitrogen circulation and destruction of biodiversity.

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

Agricultural expansion, extensive cattle ranching, and deforestation remain pressing challenges for sustainable development and climate mitigation throughout South America. In response to these challenges, national and local governments, as well as private and non-governmental actors have developed new forest conservation governance mechanisms. The objective of this study is to better understand how conservation policies interact with supply chain development to influence land use. In particular, we endeavor to understand the timing and spatial patterns of crop and cattle intensification, an understudied phenomenon that is critical to understanding the future of agricultural-forest frontiers and the impacts of conservation policies. We focus on Mato Grosso, the largest soy and cattle producing state in Brazil, which spans the Cerrado and Amazon biomes and has experienced higher levels of deforestation for agricultural expansion than any other state globally over the last decade. Using a newly created spatially explicit data set of land use intensity, supply chain development, and forest policy, we find that agricultural intensification is occurring rapidly in the region, but is only partially driven by changes in conservation policies. The intensification of cattle production is the result of improvements in deforestation monitoring, penalties, and enforcement, and increased land scarcity. Crop intensification, in contrast, preceded increases in conservation restrictions, and is associated with the positive spillovers resulting from agribusiness agglomeration and development. These results suggest that intensification is not a foregone conclusion of increasing forest conservation restrictions, but is highly dependent on wider development processes. A combined effort to direct agribusiness development away from forest regions via tax credits and subsidized credit, when applied in concert with stringent conservation requirements, could help promote intensification

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. © The Author(s) 2014.

The Meads Creek valley encompasses 70 square miles of predominantly forested uplands in the upper Susquehanna River drainage basin. The valley, which was listed as a Priority Waterbody by the New York State Department of Environmental Conservation in 2004, is prone to periodic flooding, mostly in its downstream end, where development is occurring most rapidly. Hydraulic characteristics of the unconsolidated valley-fill aquifer were evaluated, and seepage rates in losing and gaining tributaries were calculated or estimated, in an effort to delineate the aquifer geometry and identify the factors that contribute to flooding. Results indicated that (1) Meads Creek gained about 61 cubic feet of flow per second (about 6.0 cubic feet per second per mile of stream channel) from ground-water discharge and inflow from tributaries in its 10.2-mile reach between the northernmost and southernmost measurement sites; (2) major tributaries in the northern part of the valley are not significant sources of recharge to the aquifer; and (3) major tributaries in the central and southern part of the valley provide recharge to the aquifer. The ground-water portion of streamflow in Meads Creek (excluding tributary inflow) was 11.3 cubic feet per second (ft3/s) in the central part of the valley and 17.2 ft3/s in the southern part - a total of 28.5 ft3/s. Ground-water levels were measured in 29 wells finished in unconfined deposits for construction of a potentiometric-surface map to depict directions of ground-water flow within the valley. In general, ground water flows from the edges of the valley toward Meads Creek and ultimately discharges to it. The horizontal hydraulic gradient for the entire 12-mile-long aquifer averages about 30 feet per mile, whereas the gradient in the southern fourth of the valley averages about half that - about 17 feet per mile. A water budget for the aquifer indicated that 28 percent of recharge was derived from precipitation that falls on the aquifer, 32

Persistent arid conditions and population growth in the Southwest have taken a toll on the Colorado River. This has led to substantial drawdowns of many water reservoirs around the Southwest, and especially of Lake Mead, which is Las Vegas' main source of drinking water. Due to its importance, Lake Mead has received a great deal of media attention about its "bathtub ring" and the exposure of rock that used to be underwater. Drops in water levels have caused some local marinas to close, thereby affecting the aesthetic and recreational value of Lake Mead, which is located in the country's largest National Recreation Area (NRA), and surrounded by protected land. Although a rich literature analyzes how water quality impacts real estate values, relatively few studies have examined how dropping water levels are capitalized in surrounding residential properties. In this context, the goal of this study is to quantify how Lake Mead's water level changes are reflected in changes in local property values, an important source of tax income for any community. Since Lake Mead is the primary attraction within its recreation area, we are also concerned with how this recreation area, which is a few miles southeast of Las Vegas, is capitalized in real estate values of the Las Vegas metropolitan area as few valuation studies have examined how proximity to national parks influences residential property value. We estimate spatial hedonic and geographically weighted regression models of single family residences to delineate the value of proximity to the Lake Mead NRA and to understand how this value changed with Lake Mead's water levels. Our explanatory variables include common structural characteristics, fixed effects to account for unobserved locally constant characteristics, and specific variables such as distance to the Las Vegas strip and to downtown casinos. Because the sharpest declines in Lake Mead water levels happened in 2010 (NASA, 2010) and winter 2016 saw an unexpected

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.

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.

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.

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.

Unlocking the agricultural potential of Africa offers a genuine opportunity to address malnutrition and drive development of the continent. Using Senegal as a case study, to identify gaps and opportunities to strengthen agricultural policies with nutrition-sensitive approaches. We carried out a systematic analysis of 13 policy documents that related to food production, agriculture, food security, or nutrition. Next, we collected data during a participatory analysis with 32 national stakeholders and in-depth interviews with 15 national experts of technical directorates of the different ministries that deal with agriculture and food production. The current agricultural context has various elements that are considered to enhance its nutrition sensitivity. On average, 8.3 of the 17 Food and Agriculture Organization guiding principles for agriculture programming for nutrition were included in the policies reviewed. Ensuring food security and increasing dietary diversity were considered to be the principal objectives of agricultural policies. Although there was considerable agreement that agriculture can contribute to nutrition, current agricultural programs generally do not target communities on the basis of their nutritional vulnerability. Agricultural programs were reported to have specific components to target female beneficiaries but were generally not used as delivery platforms for nutritional interventions. The findings of this study indicate the need for a coherent policy environment across the food system that aligns recommendations at the national level with local action on the ground. In addition, specific activities are needed to develop a shared understanding of nutrition and public health nutrition within the agricultural community in Senegal. © The Author(s) 2015.

Full Text Available Agricultural innovation in low-income tropical countries contributes to a more effective and sustainable use of natural resources and reduces hunger and poverty through economic development in rural areas. Yet, despite numerous recent public and private initiatives to develop capacities for agricultural innovation, such initiatives are often not well aligned with national efforts to revive existing Agricultural Innovation Systems (AIS. In an effort to improve coordination and responsiveness of Capacity Development (CD initiatives, the G20 Agriculture Ministers requested the Food and Agriculture Organization of the United Nations (FAO to lead the development of a Tropical Agricultural Platform (TAP, which is designed to improve coherence and coordination of CD for agricultural innovation in the tropics. This paper presents a summary of the results obtained from three regional needs assessments undertaken by TAP and its partners. The surveyed tropical regions were Southeast Asia, Sub-Saharan Africa and Central America. The findings reveal a mismatch in all three regions between the external supply of primarily individual CD and the actual demand for institutional CD. The misalignment might be addressed by strengthening south-south and triangular collaboration and by improving the institutional capacities that would render national AIS more demand-oriented and responsive to the needs of smallholders in domestic agriculture.

The purpose of this study is to examine pragmatist constructivism as a science education referent for adult learners. Specifically, this study seeks to determine whether George Herbert Mead's doctrine, which conflates pragmatist learning theory and philosophy of natural science, might facilitate (a) scientific concept acquisition, (b) learning scientific methods, and (c) preparation of learners for careers in science and science-related areas. A philosophical examination of Mead's doctrine in light of these three criteria has determined that pragmatist constructivism is not a viable science education referent for adult learners. Mead's pragmatist constructivism does not portray scientific knowledge or scientific methods as they are understood by practicing scientists themselves, that is, according to scientific realism. Thus, employment of pragmatist constructivism does not adequately prepare future practitioners for careers in science-related areas. Mead's metaphysics does not allow him to commit to the existence of the unobservable objects of science such as molecular cellulose or mosquito-borne malarial parasites. Mead's anti-realist metaphysics also affects his conception of scientific methods. Because Mead does not commit existentially to the unobservable objects of realist science, Mead's science does not seek to determine what causal role if any the hypothetical objects that scientists routinely posit while theorizing might play in observable phenomena. Instead, constructivist pragmatism promotes subjective epistemology and instrumental methods. The implication for learning science is that students are encouraged to derive scientific concepts based on a combination of personal experience and personal meaningfulness. Contrary to pragmatist constructivism, however, scientific concepts do not arise inductively from subjective experience driven by personal interests. The broader implication of this study for adult education is that the philosophically laden

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

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 Soil is not only an important foundation for agricultural production, but also is the safeguard of human survival. Soil quality is close-ly related with food safety and argo-ecological environment. Soil fertility is the support of modern agricultural development. Multiple disci-plines and specialties are involved in researches of soil cultivating process. Nowadays, the understanding of soil fertility has changed from a-gricultural production to environmental security and resource exploitation, even larger scales to ecological health and global soil change. In this review, the characteristics and inherent link between soil and agriculture were comprehensive expounded from the aspects of long-term fertilization trials, soil cultivation techniques, and modern agriculture development. The challenge and prospect faced in soil science research field were also analyzed. Finally, several suggestions and countermeasures were proposed to the researches of soil science in future.
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.

Governments around the world have agreed to end hunger and food insecurity and to improve global nutrition, largely through changes to agriculture and food systems. However, they are faced with a lot of uncertainty when making policy decisions, since any agricultural changes will influence social and biophysical systems, which could yield either positive or negative nutrition outcomes. We outline a holistic probability modeling approach with Bayesian Network (BN) models for nutritional impacts resulting from agricultural development policy. The approach includes the elicitation of expert knowledge for impact model development, including sensitivity analysis and value of information calculations. It aims at a generalizable methodology that can be applied in a wide range of contexts. To showcase this approach, we develop an impact model of Vision 2040, Uganda's development strategy, which, among other objectives, seeks to transform the country's agricultural landscape from traditional systems to large-scale commercial agriculture. Model results suggest that Vision 2040 is likely to have negative outcomes for the rural livelihoods it intends to support; it may have no appreciable influence on household hunger but, by influencing preferences for and access to quality nutritional foods, may increase the prevalence of micronutrient deficiency. The results highlight the trade-offs that must be negotiated when making decisions regarding agriculture for nutrition, and the capacity of BNs to make these trade-offs explicit. The work illustrates the value of BNs for supporting evidence-based agricultural development decisions.

Factors like increasing population, urbanization, and climate change have made the management of water resources a challenge for municipalities. By understanding wastewater recycling for agriculture in arid regions, we can expand the supply of water to agriculture and reduce energy use at wastewater treatment plants (WWTPs). This can improve management decisions between WWTPs and water managers. The objective of this research is to develop a prototype integrated model of the wastewater treatment system and nearby agricultural areas linked by water and nutrients, using the Albuquerque Southeast Eastern Reclamation Facility (SWRF) and downstream agricultural system as a case study. Little work has been done to understand how such treatment technology decisions affect the potential for water ruse, nutrient recovery in agriculture, overall energy consumption and agriculture production and water quality. A holistic approach to understanding synergies and tradeoffs between treatment, reuse, and agriculture is needed. For example, critical wastewater treatment process decisions include options to nitrify (oxidize ammonia), which requires large amounts of energy, to operate at low dissolved oxygen concentrations, which requires much less energy, whether to recover nitrogen and phosphorus, chemically in biosolids, or in reuse water for agriculture, whether to generate energy from anaerobic digestion, and whether to develop infrastructure for agricultural reuse. The research first includes quantifying existing and feasible agricultural sites suitable for irrigation by reuse wastewater as well as existing infrastructure such as irrigation canals and piping by using GIS databases. Second, a nutrient and water requirement for common New Mexico crop is being determined. Third, a wastewater treatment model will be utilized to quantify energy usage and nutrient removal under various scenarios. Different agricultural reuse sensors and treatment technologies will be explored. The

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.

Two enzyme-linked immunosorbent assays (ELISAs) based on polyclonal antibodies (PcAbs) for clothianidin are described: colorimetric detection format (ELISA) and pattern of chemiluminescent assay (CLEIA). Clothianidin hapten was synthesized and conjugated to bovine serum albumin (BSA) and ovalbumin (OVA) to produce immunogen and coating antigen. Anticlothianidin PcAbs were obtained from immunized New Zealand white rabbits. Under optimal conditions, the half-maximal inhibition concentration (IC₅₀) and the limit of detection (LOD, IC₂₀) of clothianidin were 0.046 and 0.0028 mg/L for the ELISA and 0.015 and 0.0014 mg/L for the CLEIA, respectively. There were no obvious cross-reactivities of the antibodies with its analogues except for dinotefuran. Recoveries of 76.4-116.4% for the immunoassays were achieved from spiked samples. The results of immunoassays for the spiked and authentic samples were largely consistent with gas chromatography. Therefore, the proposed immunoassays would be convenient and satisfactory analytical methods for the monitoring of clothianidin in agricultural products.

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

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 The article considers application of the taxonomic analysis for identifying the level of development of insurance of agricultural enterprises (in case of its voluntary form in Ukrainian regions through calculation of the taxonomy ratio (development level ratio. On the basis of the conducted study the author identifies those regions of Ukraine where the level of development of insurance of agricultural enterprises, in particular, their agricultural products, is characterised with positive dynamics and those regions where the tariff policy of insurance companies needs to be reconsidered. That is why the article justifies a necessity of replacing the existing tariff policy of insurance companies with a more suitable for modern conditions of farming with the aim to ensure, on the one hand, organisation of efficient management of an insurance company and, on the other hand, taking into account interests and requirements of agricultural enterprises, which are reflected in insurance tariffs.

The paper discusses the patents that have been filed in the areas of sustainable development in agriculture, food and nutrition and use of natural resources in achieving this goal. A large number of patents deal with the production of fertilizers from animal manure, plant sources and other organic wastes, which are more sustainable that the chemical fertilizers that are being currently used. Sustainability in agriculture is achieved in developing processes for the manufacture of biopesticides/insecticides and bioactive agricultural products. Development of novel sustainable agricultural processes has also been the focus of researchers and technologists. Plant derived nutritious food products are sustainable and can cater for the growing population burden. This has been the focus of several patents. Processes for enhancing the nutrition in food also serve the purpose of catering for the under nourished population.
George Herbert Mead's theory of mind, self, and society is synthesized in this paper, as is the extension of that basic theory by Peter Berger and Thomas Luckmann.

Full Text Available The main aim of this article was to investigate the influence of payments under the CAP on economic development of different types of farms. The main source of data was FADN database. A period of research covers the years of 2004-2013. The article referred to previous results of research in the field of payments and its role for the economic situation of agricultural holdings. Then the share of payments in agricultural income was examined as well as the use of subsidies on investments. The process of accumulation, both in real and theoretical approach, and influence of this phenomenon on change of economic size were also presented. In addition the paper analysed the changes in return on equity in order to show the changes in economic efficiency of farms. The analyses that were conducted showed a significant role of payments in the formation of incomes and accumulation. On the other hand payments may lead to decrease in efficiency. In long term there is a risk that dependence on payments in functioning of farm will be excessive.
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.

This paper is a comparative study of the role of agriculture in economic development in sub-Saharan Africa and Asia. Popular notions of economic duality and agricultural squeeze in sub-Saharan Africa are re-examined, and new explanations in terms of agrarian structures and resource availabilities are put forward to account for the apparent economic duality in that continent. Comparison with surplus labour economies of Asia highlights the constraints posed by the prevailing agrarian structures...
Traditionally, development economists had a dim view of the contribution that farmers made to modern economic growth, compared with manufacturers. Hence agricultural exports and manufacturing imports were often taxed. This view changed over time though, as first economists and then policy makers came to understand the high cost of an anti-agricultural, import-substituting industrialization strategy. This paper outlines how this change came about and the resulting economic policy reforms that ...
Full Text Available The paper aimed to analyze the development of organic agriculture in the world, the EU and Romania, based on the statistical data for the period 2006-2010 and the index, share and comparison methods. Organic agriculture covers 34.04 Million ha at world level, of which 26.99 % in Europe and 32.08 % in Oceania. The largest areas in organic agriculture are in Australia, Argentina, the USA, Brazil, Spain, China and Italy. At world level, there are 1.6 million organic producers, over 63 % operating in Africa and Asia, especially in India, Uganda and Mexico. In 2010, organic food sales accounted for Euro 44.5 Billions of which 50 % in Europe. In the same year, the organic agriculture area increased by 20 % in the EU-27 and reached 9.01 million ha and continues to grow, representing 5.10 % of agricultural land. The larges areas in organic agriculture are in Spain, Italy, Germany and France. In the EU-27 there are 219,290 organic producers of which 40 % in Italy, Spain, Germany and Austria. In 2010, Romania’s area in organic agriculture was 300,205 ha, 2 times higher than in 2006. A number of 10,253 organic operators were registered in 2010, representing 4.67 %, of the EU number. The main organic products are cereals, vegetables, wine, honey, dairy products, representing a chance for Romania’s export on the EU market.
Full Text Available Objective – This paper attempts to highlight the farmers’ lives in Malaysia and their problems in developing idle agricultural land.Methods - This paper is using descriptive and exploratory method of study which refer to the situation of agricultural sector in Malaysia.Results - The scheme aPLS (agricultural production and loss sharing that proposed cannot stand alone in the traditional fiqh to be implemented now. Therefore, the combinations of aPLS contract with ujrah principle are really needed. This is important to ensure the flexibility of the contract that can offer a fully comprehensive scheme of Islamic agricultural finance.Conclusion – The land together with labour can be considered as a form of capital and therefore has a similarity to the contracts of mudaraba and musharaka. Hence, it can be said that these principles are “agricultural production and loss sharing (aPLS” because land will naturally produce an output or a product. Muzara’a and musaqa therefore can be said to be contracts which are based on sharing output rather than sharing profit.Keywords: Idle Agricultural Land, Islamic agricultural finance, Malaysia

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

Full Text Available Planning and distribution economy with state ownership of agricultural enterprises, which were dominant in the early 90s the economy of the country, was unable to provide normal functioning of the agricultural land use in the conditions of transition to market relations. To switch to another economic system began a gradual process of transformation of agricultural enterprises. The result of this process was the change in the structure of agrarian enterprises due to privatization and raspaevaniya land, and appearance from small-scale farms to large agricultural enterprises. Today identified market actors (enterprises in agriculture: business companies, private enterprises, production cooperatives, farmers, public enterprises, other forms of management. The most common kind of private business are farms. They are one of the most promising and effective forms of management with high agriculture, appropriate level of production organization, prudent attitude to the land and best landscaping. However, today the formation of farming in Ukraine has not yet reached the level of development, which is observed in economically developed countries. The overall economic decline and inadequate legislation has forced farmers to rely on themselves. Notes the insufficient level of their competitiveness, making it impossible to provide the expanded reproduction, determines the risk of insolvency and, as a consequence, leads to bankruptcy. Farmers receive government support, but it is weak and temporary, which greatly impedes their development. Practical state support only a few farms that can affect the distribution of funds. Agricultural cooperation is one of the effective forms of management, which aims to unite the producers in the direction of increase of efficiency of use of their resource potential. However, today there are a number of unresolved problems that hinder the effective development of agricultural cooperatives. Since 2000 years, the initiative in

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.
Full Text Available The Republic of Serbia is very convenient for agricultural production: large, high-quality arable land, favourable climate conditions for all agricultural cultures, rich flora and fauna, rich tradition and developed scientific institutions are the priceless treasure of Serbian agriculture. However, the results of numerous research show that Serbian agriculture competitiveness is based on cheap production factors compared to other countries (soil, workforce, other inputs. One of the ways of solving this situation is larger application of entrepreneurial type of production in agribusiness, for which there are great possibilities in Serbia. This paper analyses the position of agriculture at the moment, and points out the importance and the need for faster and wider development of an entrepreneurial orientation in this sector. Serbia is in the EU accession process, and therefore the imperative of approaching the European model of doing business and the need for companies and family economies in agribusiness to build and protect their competitive advantages. In order to achieve this goal, traditional weaknesses should be overcome, so education and introduction of entrepreneurship into the school system are a good basis for farmers to have a stronger influence on the economic policy carriers as well as the adequate treatment of agricultural sector at the macroeconomic level.

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.
Full Text Available Because organic systems present complex environmental stress, plant breeders may either target very focused regions for different varieties, or create heterogeneous populations which can then evolve specific adaptation through on-farm cultivation and selection. This often leads to participatory plant breeding (PPB strategies which take advantage of the specific knowledge of farmers. Participatory selection requires increased commitment and engagement on the part of the farmers and researchers. Projects may begin as researcher initiatives with farmer participation or farmer initiatives with researcher participation and over time evolve into true collaborations. These projects are difficult to plan in advance because by nature they change to respond to the priorities and interests of the collaborators. Projects need to provide relevant information and analysis in a time-frame that is meaningful for farmers, while remaining scientifically rigorous and innovative. This paper presents two specific studies: the first was a researcher-designed experiment that assessed the potential adaptation of landraces to organic systems through on-farm cultivation and farmer selection. The second is a farmer-led plant breeding project to select bread wheat for organic systems in France. Over the course of these two projects, many discussions among farmers, researchers and farmers associations led to the development of methods that fit the objectives of those involved. This type of project is no longer researcher-led or farmer-led but instead an equal collaboration. Results from the two research projects and the strategy developed for an ongoing collaborative plant breeding project are discussed.

Full Text Available Sustainable development has become the main focus of the global development agenda as presented in the 2015 Sustainable Development Goals (SDGs. However, for countries to assess progress, they need to have reliable baseline indicators. Therefore, the objective of this paper is to develop a composite baseline index of the agriculture-related SDGs in Southern Africa to guide progress reporting. The paper identified eight of the SDG indicators related to the agriculture sector. The paper relies on data for indicators from five SDGs (SDGs 1, 2, 6, 7 and 15. Applying the arithmetic mean method of aggregation, an agriculture-related SDG composite index for Southern Africa between zero (0 = poor performance and 100 (best possible performance was computed for thirteen countries that had data on all identified indicators. The results show that the best performing countries (Botswana, Angola, Namibia, Zambia and South Africa in the assessment recorded high scores in SDGs 1, 2 and 7. The three countries (Democratic Republic of Congo, Zimbabwe and Madagascar that performed poorly on both SDG 1 and 2 also had the least scores on the overall agriculture-related SDG composite index. The water stress indicator for SDG 6 recorded the worst performance among most countries in the region. Possible approaches to improve the contribution of agriculture to SDGs may include investing more resources in priority areas for each agriculture-related SDG depending on baseline country conditions. The implementation, monitoring and evaluation of regional and continental commitments in the agriculture sector and the SDGs are critical for achievement of the targets at the national and local levels. While the methods employed are well-grounded in literature, data unavailability for some of the SDGs in some countries presented a limitation to the study, and future efforts should focus on collecting data for the other SDGs in order to permit a wider application.

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.

Agricultural ecological compensation has drawn an increasingly broad range of interest since early 1990s. In recent years, the volume of the literature grows rapidly. As a result, a systematic review of the diverse research field and its current trends becomes essential. This paper surveys the literature of agricultural ecological compensation between 1990 and 2016. Specifically, by employing CiteSpace information visualization software, we firstly identified the research hotspots and evolution path and then illustrated the frontier and developing trend of the domain in core and broader perspectives. It is found that the focus of the academic community has always been researches on the theoretical policy and application of the payment for agro-ecosystem services, agricultural ecological compensation based on contingent valuation method, and ecological compensation of farmland landscape and organic food production as well as willingness to accept/pay for land use and ecological protection. Meanwhile, we also found that, in recent years, qualitative research has received more and more attention in the field of agricultural ecological compensation, since global warming, agricultural carbon emissions, and other emerging environmental issues have aroused widespread concern of the people around the world. Moreover, we believed that more and more scholars will employ case study methodology to analyze agricultural ecological compensation in specific systems, regions, or circumstances in the future.

This paper reviewed the main achievements of nuclear agricultural sciences, analyzed its developmental gap and provided some thoughts on its future development in China. Since the research and application of nuclear agricultural sciences was initiated in 1956, it has penetrated into the main fields of agriculture and made outstanding achievements, in some fields, China keeps a leading place in the world. By the end of 2001, China obtained 625 mutant varieties and strains, accounting for 27.2% of the total number in the world. The total planting area of the mutant varieties amounted to about 9 million hectares, and brought about an annual increase of grains by 3-4 million tons, cotton by 1.5-1.8 million tons, oilseeds by 0.75 million tons, with total annual economic benefit of 3.3-4.0 billion RMB Yuan. Among the released mutant varieties, 18 were awarded the national innovation prize. China approved national hygiene standards for 6 classes of irradiated foods, and 17 national technological standards of irradiated foods. The annual amount of irradiated foods and agricultural commodities ranged from 80-100 thousand tons. In general, the application of nuclear agricultural sciences in mutation breeding, space breeding, agricultural isotope tracers, food irradiation, sterile insect technique and radiation hormesis, has made considerable advancement and gained tremendous economic, social as well as ecological benefits. As a result, the IAEA and its technical officials highly evaluated nuclear agriculture in China. In 1999, China was approved as the RCA lead country for thematic agriculture. In considering its future development, the focus should be placed on the applied basic research and the development of some key technologies, and endeavor to make some breakthroughs in the molecular mechanism of mutation breeding and space breeding, irradiation quarantine technology , isotope tracing in environmental protection, animal health and production. The general objective is

In 2011, in response to global food crises, the G20 Agricultural Ministers launched a satellite-based global agricultural monitoring initiative to develop the Group on Earth Observations Global Agriculture Monitoring (GEOGLAM) system. The GEO is aimed at enhancing the availability and use of both satellite and in situ data for societal benefit. This initiative builds on the observation requirements developed by the GEO Agricultural Community of Practice, the understanding that no one satellite system can currently provide all the data needed for agricultural monitoring and the resulting recommendation for improved acquisition and availability of data by the World's space agencies. Implicit in this recommendation is the fact that certain regions of the Earth are imagery rich while others are imagery poor, leaving knowledge gaps about agricultural processes and food supply for certain areas of the World. In order to respond to these knowledge gaps and to strengthen national, regional, and global agricultural monitoring networks, GEOGLAM is working with the Committee on Earth Observations (CEOS), the space arm of GEO, to develop a coordinated global acquisition strategy. A key component of GEOGLAM is an effort to articulate the temporal and spatial Earth Observation (EO) requirements for monitoring; second, the identification of current and planned missions which are capable of fulfilling these EO requirements; and third, the development of a multi-agency, multi-mission image acquisition strategy for agricultural monitoring. CEOS engineers and GEOGLAM scientists have been collaborating on the EO requirements since 2012, and are now beginning the first implementation phase of the acquisition strategy. The goal is to put in place an operational system of systems using a virtual constellation of satellite-based sensors acquiring data to meet the needs for monitoring and early warning of shortfalls in agricultural production, a goal that was articulated in the 1970's

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 Conventional agriculture uses mechanization practices, remediation and soil fertilization and pesticides to control pests and diseases. The criticism of this farming system grows as studies show that pesticides contaminate food and the environment and cause health damage. Aiming at sustainable development and the pursuit of consolidation between the social, economic and ecological agriculture alternative arises. This work is outlined in order to understand the current status, characteristics, limitations and difficulties for the implementation of alternative agriculture in the municipality of Ubá-MG. Furthermore, we seek to identify the knowledge of agricultural alternative as well as the interest and profile of likely consumers of these products in the municipality. We conducted a quantitative research through the use of two questionnaires with multiple choice questions and dichotomous, by simple random sampling. The results show that there are many difficulties for the development of alternative agriculture in the county, including: a lack of resources for producers, small-scale production, lack of market and consumer knowledge about alternative product in the municipality. Given these difficulties, the alternative system seems advantageous and competitive both economically and environmentally compared to the conventional system. There was a lack of information regarding organic products, alternative, since access to these is restricted to much of the population in the municipality of Ubá and adjacent municipalities. Seeking theoretical basis it was necessary also to perform a literature search in several papers that address the theme.
Full Text Available The background of this study is that Dewa Starfruit as a local resource in Depok City is threatened with extinction. The absence of regulations that protect these local resources and high rate of land use conversion causes decreasing number of starfruit plants and production. Starfruit farmers tend to switch professions to non-agricultural occupations. In national level, the largest number of agricultural business households experienced the greatest decline in horticulture subsector by 37.4% (Agricultural Census 2013. The elected regional head has branded Depok City with the tagline "friendly city" replacing Dewa Starfruit. The government's orientation and support for Dewa starfruit is fading away. Therefore, Depok City Government, especially DKP3, need to develop local resource-based agriculture development plan in order to be able to maintain local resources while improving it for society welfare. This research uses qualitative approach. The research informants were DKP3 apparatus of Depok City, Bappeda (Regional Government apparatus of Depok City, field officer and farmer group. Data collection techniques used in-depth interviews and documentary studies. Data analysis utilized interactive model. Research results indicate that the development of local resource-based agricultural development plans has not gone well. Despite various supporting factors, there are existing inhibiting factors which are land use conversion had never been discussed; DKP3 Depok City efforts to safeguard agricultural issues in musrenbang has not been optimal; no field data update, either by couseling workers or farmers; DKP3 Depok City prioritized RPL activity; uneducated farmers; and absence of regional head support.
Full Text Available Introduction. Agriculture is one of the largest and most important sectors of the Ukrainian economy. The food security and independence of the state, the state of the internal and external markets, and, consequently, the standard of living of the population are directly dependent on its functional state. Mykolaiv region has significant opportunities for the development of the agricultural sector. There are favorable natural and climatic conditions, fertile land, labor resources and long-standing cultivating traditions. The region is considered one of the regions of intensive agriculture in Ukraine and has significant land resources. Purpose. The article presents the analysis of the development of production and sale of crop production by the agrarian enterprises of the Mykolaiv region, as well as revealing ways to increase the volume of their production and sales. Results. The crop area of main agricultural crops in all categories of farms was analyzed, and structural changes for 2010-2016 were revealed. The priority branch of the agro-industrial complex, which has an important strategic significance, first of all, is determined by the level of production of which the food security of the state depends, its economy and welfare of the population. The dynamics of agricultural crop yields in agrarian enterprises as the determining factor of influence on the efficiency of activity in the field of plant growing is researched. The dynamics of gross collections of crop production in agricultural enterprises is analyzed and the contribution of the Mykolaiv region to the national production of grain is determined. The volumes and average prices of sales of agricultural products by agrarian enterprises are investigated and it is determined that the modern development of the agrarian sector of the economy requires special attention to the formation and activation of the activities of market infrastructure entities. The production of which crops are an

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.
Many developing nations, especially the least developed countries, are subjected to recurrent spells of food insecurity. In order to understand food insecurity in these countries it is necessary to consider not only immediate or trigger-causes of food crises, but also its underlying or systemic causes. This paper argues that the agricultural support measures of advanced countries may act as a systemic cause for food insecurity in developing countries. While the import of subsidized foods by d...

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.
The objective of this project is to develop and improve tools for the ethical assessment of new technologies in agriculture and food production in general and modern biotechnologies in particular. The project thus responds to the plurality of consumer concerns that increasingly inform the European

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 We have started from the analysis of existing human resources in the paper, from the point of view of regional, qualification and age structure of the active labour force. Basic research method is deduction method, because we start from the general towards special and individual, with the aim to bring human factor and development of agriculture in Montenegro into connection. With regards to the key role of the human factor in the development of agriculture, a question emerges: is this factor in Montenegro a real opportunity or a constraint? Upon having insight into the existing situation of the human factor, we can conclude that there is an obvious discrepancy between demographic and economic centres. Expressed migration of the population from the north towards the south and from villages to cities brought the development of agricultural production into question. When the human factor engaged in agriculture is concerned, old population and elderly households prevail, which is a serious threat to the development, because depopulation and 'senilization' caused abandoning villages, deagrarization and space devastation.

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 is aimed at studying the basic aspects of establishment and development of the land market. A mechanism for securing against the leasehold estate and a model of an agricultural land market have been proposed. It has been specified that the most important component on formation of land market in our State is to work to change public opinion, people attitudes regarding the private ownership of land and deals with it. The proposed mechanism for securing against the leasehold estate has not only economic, but also social significance, which, above all, is that securing against the leasehold estate does not change the owner of the land, and, consequently, does not threaten villagers with dispossession of land. With introduction of the presented model of an agricultural land market it can be argued that such a market is an open, complex system based on the interaction between its actors over the use, disposal and market turnover of agricultural lands.
Under the background of rapid agricultural economic development,rural financial and accounting work is of great significance. From rural accounting management system,rural accountant allocation and rural accounting training,this paper analyzes current situations of rural accounting work in China. In rural financial and accounting work,there are following problems. ( 1) Accounting behavior is not standard,and basic accounting work is to be further strengthened; ( 2) Internal control is not perfect and implementation of supervision mechanism is formalized; ( 3) Few people manipulate accounting behavior and accounting information is not transparent. In view of these problems,it puts forward countermeasures for improving rural accounting work: ( 1) establishing perfect agricultural accounting system; ( 2) regulating fund management order; ( 3) promoting computerized agricultural financial and accounting work; ( 4) improving professional and comprehensive quality of rural accountants.
During recent months, another sign of the global fragility to sustain the increasing human demand for resources has appeared with merciless cruelty. Increasing food prices, paradoxically driven to a large extent by the rapid economic growth of vast regions of the emerging world, are affecting hundreds of millions of the poorest people in Africa, Asia, and Latin America. As described in Science for Agriculture and Rural Development in Low-Income Countries, most of the poorest people in these low-income countries live in rural areas and are engaged in agriculture or related activities. Because many people in these areas are engaged in subsistence agriculture, they do not share in the added income derived from higher market prices for food.

According to the 2012 IPCC SREX report, extreme drought events are projected to become more frequent and intense in several regions of the world. Wide and timely monitoring systems are required to mitigate the impact of agricultural drought. Therefore, FAO's Global Information and Early Warning System (GIEWS) and the Climate, Energy and Tenure Division (NRC) have established the `Agricultural Stress Index System' (ASIS). The ASIS is a remote sensing application that provides early warnings of agricultural drought at a global scale. The ASIS has first been designed and described by Rojas et al. (2011). This study focused on the African continent and was based on the back processing of low resolution data of the NOAA-satellites. In the current setup, developed by VITO (Flemish Institute for Technological Research), the system operates in Near Real Time using data from the METOP-AVHRR sensor. The Agricultural Stress Index (ASI) is the percentage of agricultural area affected by drought in the course of the growing season within a given administrative unit. The start and end of the growing season are derived per pixel from the long term NDVI average of SPOT-VEGETATION. The Global Administrative Unit Layer (GAUL) defines the administrative boundaries at level 0, 1 and 2. A global cropland and grassland map eliminates non-agricultural areas. Temperature and NDVI anomalies are used as drought indicators and calculated at a per pixel base. The ASIS aggregates this information and produces every dekad global maps to highlight hotspots of drought stress. New developments are ongoing to strengthen the ASIS to produce country specific outputs, improve existing drought indicators and estimate production deficits using a probabilistic approach.

This analysis assesses the factors underlying Charles Horton Cooley's place in the sociological canon as they relate to George Herbert Mead's puzzling diatribe-echoed in secondary accounts-against Cooley's social psychology and view of the self published scarcely a year after his death. The illocutionary act of publishing his critique stands as an effort to project the image of Mead's intellectual self and enhance his standing among sociologists within and outside the orbit of the University of Chicago. It expressed Mead's ambivalence toward his precursor Cooley, whose influence he never fully acknowledged. In addition, it typifies the contending fractal distinctions of the scientifically discursive versus literary styles of Mead and Cooley, who both founded the interpretive sociological tradition. The contrasting styles and attitudes toward writing of the two figures are discussed, and their implications for the problems of scale that have stymied the symbolic interactionist tradition are explored.
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.
Full Text Available Although agricultural value chain resilience is a crucial component to food security and sustainable food systems in developing countries, it has received little attention. This paper synthesizes knowledge from the social-ecological systems (SES, supply chain management, and value chain development literature to make three contributions to this research gap. First, we conceptualize agricultural value chain resilience and relate it to overall food system resilience. Second, we identify seven principles that are hypothesized to contribute to SES resilience, relate them to supply chain management theory, and discuss their application in agricultural value chains. A key insight is that the appropriateness of these principles are important to assess on a case-by-case basis, and depend in part on trade-offs between resilience and other dimensions of value chain performance. Third, we integrate two common tools, the Resilience Alliance’s assessment framework and value chain analysis techniques, to outline an adaptable participatory approach for assessing the resilience of agricultural value chains in developing countries. The objectives of the approach are to cultivate a chain-wide awareness for past and potential disturbances that could affect food security and other essential services provided by the value chain, and to identify upgrades that can build resilience against these key disturbances.

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

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.

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)

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.

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. © 2012 Wiley Periodicals, Inc.

This essay uses previously unpublished correspondence of George Herbert Mead to tell the story of his involvement in the aftermath of a political dispute that took place at the University of Wisconsin during the years 1914-1915. It seeks thereby to clarify the historical significance of an article he published on this controversy in late 1915. Taken together with relevant information about the educational activities of William H. Allen of the New York Bureau of Municipal Research, Mead's correspondence and article throw helpful light upon his understanding of how an educational survey of a university should proceed; they also show how he went about the task of evaluating a failed attempt at such a survey.

Full Text Available This paper examines the role of rainfall in the urban development of Kenya. The rainfall characteristics have been analysed and their influence on agricultural and urban development assessed. It is noted that since Eldoret is one of the rapidly expanding towns in Kenya located in highly potential agricultural region, variability of rainfall and drought can seriously affect urban development as farmers in the hinterland will abandon their farms and migrate to the town thus creating food shortage. Secondly, in times of drought, the water supply problems in the town will be exacerbated as it depends on surface water source. The tempo of rural-urban migration will be speeded up and this will create more socio-economic problems.
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.

Full Text Available The successful development of Northern and Arctic areas depends on sustainable functioning of the agricultural sector. Agriculture and fishing agriculture is a way of life of the indigenous population. The article discusses the state of agriculture and food self-sufficiency in the Komi Republic in the years of relatively stable development (1960–1980 and in the conditions of market reforms. It analyzes production and consumption of food and shows a positive effect of modernization processes on the agricultural sector in the pre-reform period. It studies market transformation of the agrarian economy, accompanied in the 1990s by the sharp decline in agricultural production, degradation of productive capacity, rural demography, rural infrastructure, decrease in living standard of farmers, and disparity of prices on agricultural and industrial products. The paper discloses trends in food self-sufficiency of the northern region in 1980–2013 and reveals reasons for the decrease in its level in the period of market reforms. It considers possible scenarios to develop the agrarian sector and food self-sufficiency. To predict the agriculture development the author identifies strong and weak sides, opportunities and threats by means of SWOT-analysis. The article proposes 3 scenarios: inertial (pessimistic, baseline and optimistic. It finds out the most reasonable optimistic development scenario based on innovative modernization for the Komi Republic. The study results can be used to adjust the current State program of agricultural development and elaborate the strategy of the agro-food sector of the region

In snow-covering region of Japan, the promotion of snowmelting with application of agricultural snowmelting agents ('Yusetsuzai' in Japanese) has been widely carried out by farmers at the snowmelting season. When black colored materials with albedo-lowering effect are spread on snow surface, absorption of solar radiation by snow is increased, the snowmelting is promoted and snow thawing date becomes earlier. As a result, the growing season of crop plants is extended. Existing agricultural snowmelting agents have been mostly made from industrial waste materials or industrial processed products due to requirement for the low cost of the raw materials. These agents may contain harmful heavy metal elements and may lead to environmental pollution. To solve these problems, we developed the new agricultural snowmelting agents made from recycled bio-waste materials generated from the fields of agriculture and fishery. The developed snowmelting agents were made from shells of Patinopecten yessoensis, fowl droppings and processed wastes of fish and shellfish, etc. Especially, the shells of Patinopecten yessoensis has problems due to generation of a huge quantity in Hokkaido. Therefore, the recycling-use of these waste materials was strongly requested and expected. The developed snowmelting agents were possible to spread efficiently and safely on the snow-surface without wide scattering by controlling the particle size within the range larger than 100 microm and smaller than 1180 microm. Results obtained from the field experiment showed that the albedo was decreased from 0.70 for natural snow to 0.20 and the promotion of snowmelting for 11 days was recognized when 100 kg/10a of developed agent was spread. The promoting ability of the developed agent was equivalent to those of the existing commercial snowmelting agents. (author)

Full Text Available The need to strengthen the connection between academia and society has received increased attention over the past years. The importance of bringing university students closer to stakeholders in society as part of their learning process is high regarding sustainable agriculture, because of its applied approach. University programs based on experiential and action-oriented learning have been developed over the past decades, but more knowledge is needed about the impact of these educational activities. In a short course in sustainable agriculture at the University of Gastronomic Sciences in Bra, Italy, we examined the impacts of experiential and action-oriented learning on competency development as well as transformational impacts on the students. We found that students improve on several core competences as a result of their participation in the short course, and also signs of deep transformational processes among the students.

Full Text Available The subject of the author’s research is the processes of development of the agrarian sector of Ukrainian economy by ecological-economic specifications. The methodological justification is based on the use of fundamental principles that reflect the main strategies of agrarian development. The systematic approach to the characteristics of the agrarian system, complex by the structure and functional parameters in interaction with the external environment, is applied. Methods of analysis/synthesis are used for the disclosure of the integral nature of the agrarian environment in the context of management of the main processes. The purpose of the author’s research suggests a consideration of the processes of formation of the agrarian system by economic and environmental interactions as modern dominant in the development of the agrarian sector of Ukraine. The analysis of integral components of agrarian development with the reflection of interactions of the sphere of agrarian production and agrarian relations is carried out. The emphasis is made on the importance of the formation of an effective and promising domestic agricultural policy, in the basis of which is the activation of entrepreneurial initiatives, comprehensive development of the agrarian community, ecologically and socially oriented projects of reproduction of rural territories, innovative strategies of ecological and economic ascension of agriculture in Ukraine. The resource base is considered as the economic basis of agriculture from the standpoint of the main sales markets, the state of transport infrastructure, the growth of world and domestic demand for agrarian raw materials and finished products, and the availability of relatively cheap labour resources. The agrarian production is analysed from ecological positions and influences of natural and climatic factors. The state of individual agro-ecological mismatches in agriculture of Ukraine is explained, as well as the reasons of
Full Text Available The designation, conservation and tourism development of agricultural heritage systems, which are embedded with intricate human–nature relations, could significantly influence community livelihoods. Therefore, a livelihood approach is critical for agricultural heritage conservation and the sustainability of the hosting community. Taking Guanhou Village, Xuanhua Grape Garden Urban Agricultural Heritage Site as an example, this study examines impacts of heritage conservation and tourism on the community livelihood system and its implications for community livelihood sustainability. A sustainable livelihood framework is adopted to guide the analysis. Face-to-face in-depth interviews were conducted with management officials, village leaders and village residents. The research identified the importance of Globally Important Agricultural Heritage Systems (GIAHS designation on raising government support and public awareness on conservation. Tourism emerges as an alternative livelihood to some residents which exerts positive economic influence. However, tourism participation is currently at a low level which restricted the distribution of benefits. The sustainability of local rural livelihood is at risk due to the rapid urbanization, the decline of human resources and the insufficient integration of traditional agriculture with tourism. Practical implications were discussed to enhance local participation and tourism contribution to GIAHS conservation.
Full Text Available This paper presents a novel approach that could be used for scientifically verified group decision making for the allocation of budget funds on agricultural loan programs in the Provincial Fund for Agricultural Development of Vojvodina Province in Serbia. An approach is structured based on the Analytic Hierarchy Process, a recognized multi-criteria method suitable for supporting both individual and group decision making processes. The decision makers' weights in a group are derived in an objective manner and based on demonstrated individual consistency while assessing and evaluating elements within the decision-making framework. A real life application is used to demonstrate how the four key decision-makers can individually evaluate and rank agricultural loan programs and how their decisions are afterwards compiled into the final consensus based group decision.

Conservation planning information is important for identifying options for watershed water quality improvement and can be developed for use at field, farm, and watershed scales. Translation across scales is a key issue impeding progress at watershed scales because watershed improvement goals must be connected with implementation of farm- and field-level conservation practices to demonstrate success. This is particularly true when examining alternatives for "trap and treat" practices implemented at agricultural-field edges to control (or influence) water flows through fields, landscapes, and riparian corridors within agricultural watersheds. We propose that database structures used in developing conservation planning information can achieve translation across conservation-planning scales, and we developed the Agricultural Conservation Planning Framework (ACPF) to enable practical planning applications. The ACPF comprises a planning concept, a database to facilitate field-level and watershed-scale analyses, and an ArcGIS toolbox with Python scripts to identify specific options for placement of conservation practices. This paper appends two prior publications and describes the structure of the ACPF database, which contains land use, crop history, and soils information and is available for download for 6091 HUC12 watersheds located across Iowa, Illinois, Minnesota, and parts of Kansas, Missouri, Nebraska, and Wisconsin and comprises information on 2.74 × 10 agricultural fields (available through /). Sample results examining land use trends across Iowa and Illinois are presented here to demonstrate potential uses of the database. While designed for use with the ACPF toolbox, users are welcome to use the ACPF watershed data in a variety of planning and modeling approaches.

The South African Department of Water Affairs and Forestry (DWAF) has started developing a strategy to regulate activities and water uses by the agricultural sector that could impact on the water resource quality. The aim would not be to over-regulate the sector, but to protect the water resource where necessary. Most of these activities constitute diffuse sources of potential pollution. The strategic process will start with investigative discussions with major stakeholders and determining the strategic context and current situation. The latter will consist of a detailed literature and stakeholder survey, and an evaluation of existing agricultural activities. The next steps of determining a vision and the setting of strategic objectives will be done with active participation by the major players. An action plan will be developed to achieve the set objectives. Important components of the strategy will be to: classify activities according to their risk to the water resource, taking into account the sensitivity of the water resource; set regulatory measures in accordance with the risk posed by the activity (measures could include the promulgation of regulations, general authorisations and/or issuing of licenses); harmonise and link the process with existing relevant processes and guidelines within DWAF and other government departments; review existing guidelines; sign agreements with relevant government departments and the agricultural sector; and provide training, built capacity and raise awareness during and after the process.

Under used crops are those crop species which have high potential value in the supply of important raw material for secondary economy sector in food processing. The yield production of new Under used crops varieties can be used as an important input in food production process for export products. The optimum production cost can be minimized since the price of raw material supplied from agriculture sector is cheaper compared with the international markets. Agriculture output can be increased through the development of Under used crops using radiation mutagenesis and tracer technique for good agricultural practices. This paper work will discuss the development procedure of mutation induction method which includes irradiation of samples such as seeds of groundnut and in vitro shoots of banana using gamma rays and application of N-15 for nutrient use efficiency and screening of potential mutant lines with high yield and resistance to drought. These management practices using established procedures of water and nutrient use efficiency will be recommended to the growers. (author)

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.

China is now the third largest bioethanol producer in the world after the United State and Brazil. The overall goals of this paper are to provide an overview of China's current bioethanol program, its future trend, and the likely impacts on its agricultural economy in the future. The analysis shows that China has developed an ambitious long-run biofuel program with a series of financial and institutional supports. While there are several potential feedstock crops available for bioethanol production, lack of land for feedstock production is one of major constraints in China's bioethanol expansion. The results show that although China's bioethanol expansion will have little impacts on overall agricultural prices in international markets, it will have significant impacts on the prices, productions, and trade of those energy crops being used for bioethanol production in China.

Full Text Available Agriculture is a very important sector of Kosovo economy. Seeing the big agriculture sector’s need for crediting, this paper is focused on credit policies of micro financial institutions, by emphasizing their impact in the development of agriculture. Since the number of micro financial institutions in Kosovo is quite big and analyzing the crediting policies of all of them is impossible, for comparing analyzes this paper focuses in three of them. Several clients of the micro financial institutions were surveyed to check the impact that the loans they took had on the development of their agricultural activity. The survey includes the entire territory of Kosovo, meaning, clients of different regions were surveyed including minority-inhabited zones. Micro loan has become a support for many farmers, artisans and traders of various Kosovo rural zones. The micro loan makes it possible to have access to financial services for funding small projects in the field of agriculture, cattle-raising or in service sectors, such as artisans, small grocery shops, etc. The main goals of this research is to analyze the credit policies of MFIs operating in Kosovo and their impact in development of agriculture; a comparative analyses of impact of these credit policies in development of agriculture and identification of new crediting policies that might impact further agricultural development.

Improving land productivity is essential to meet increasing food and forage demands in hillside and mountain communities. Tens of millions of smallholder terrace farmers in Asia, Africa, and Latin America who earn $1-2 per day do not have access to peer-reviewed knowledge of best agronomic practices, though they have considerable traditional ecological knowledge. Terrace farmers also lack access to affordable farm tools and inputs required to increase crop yields. The objectives of this review are to highlight the agronomic challenges of terrace farming, and offer innovative, low-cost solutions to intensify terrace agriculture while improving local livelihoods. The article focuses on smallholder farmers in developing nations, with particular reference to Nepal. The challenges of terrace agriculture in these regions include lack of quality land area for agriculture, erosion and loss of soil fertility, low yield, poor access to agricultural inputs and services, lack of mechanization, labor shortages, poverty, and illiteracy. Agronomic strategies that could help address these concerns include intensification of terraces using agro-ecological approaches along with introduction of light-weight, low-cost, and purchasable tools and affordable inputs that enhance productivity and reduce female drudgery. To package, deliver, and share these technologies with remote hillside communities, effective scaling up models are required. One opportunity to enable distribution of these products could be to "piggy-back" onto pre-existing snackfood/cigarette/alcohol distribution networks that are prevalent even in the most remote mountainous regions of the world. Such strategies, practices, and tools could be supported by formalized government policies dedicated to the well-being of terrace farmers and ecosystems, to maintain resiliency at a time of alarming climate change. We hope this review will inform governments, non-governmental organizations, and the private sector to draw

Full Text Available Inland valleys are becoming increasingly important agricultural production areas for rural households in sub-Saharan Africa due to their relative high and secure water availability and soil fertility. In addition, inland valleys are important as water buffer and biodiversity hot spots and they provide local communities with forest, forage, and fishing resources. As different inland-valley ecosystem functions may conflict with agricultural objectives, indiscriminate development should be avoided. This study aims to analyze the diversity of inland valleys in Sierra Leone and to develop guidelines for more precise interventions. Land use, biophysical and socio-economic data were analyzed on 257 inland valleys using spatial and multivariate techniques. Five cluster groups of inland valleys were identified: (i semi-permanently flooded with high soil organic carbon (4.2% and moderate available phosphorus (10.2 ppm, mostly under natural vegetation; (ii semi-permanently flooded with low soil organic carbon (1.5% and very low available phosphorus (3.1 ppm, abandoned by farmers; (iii seasonally flooded with moderate soil organic carbon (3.1% and low available phosphorus (8.3 ppm, used for rainfed rice and off-season vegetables produced without fertilizer application for household consumption and market; (iv well drained with moderate soil organic carbon (3.8% and moderate available phosphorus (10.0 ppm, used for rainfed rice and off-season vegetables produced with fertilizer application for household consumption and market; and (v well drained with moderate soil organic carbon (3.6% and moderate available phosphorus (11 ppm, used for household consumption without fertilizer application. Soil organic carbon, available phosphorus, hydrological regime, physical accessibility and market opportunity were the major factors affecting agricultural intensification of inland valleys. Opening up the areas in which inland valleys occur through improved roads and

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

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.
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 In the context of the division of accounting into financial accounting, taxation accounting, management accounting and statistical accounting a problem of improving their relationship arises. The accounting and analytical cluster plays the role of the correlating factor of the relationship between the subdivisions of the agricultural holding property. To improve its work a modular principle of its building based on information technology was introduced. Practical implementation of modular accounting and analytical cluster revealed its shortcomings. They were as follows: each type of account and each production unit used its own natural and cost parameters. The number and nature of these parameters were different. To eliminate the shortcomings in the information security of managers and specialists of the agricultural holding, we attempt to develop a methodology for establishing a rational number of descriptors (binding parameters for each module. The proposed descriptors are designed on the basis of validity of the methodological approach to their calculations and legal support. The proposed method allowed to limit the asymmetric information in all kinds of records, to improve its quality and to bring a synergistic effect from the scale and structure of the use of the agricultural holdings property complex.

A dynamic food chain model DYNACON was developed to simulate the radionuclide transfer on agricultural ecosystems. DYNACON estimates the radioactivity in each compartment of food chains for three radionuclides, nine plant species and five animal products as a function of the deposition date. A number of the parameter values used in this study are representative of Korean agricultural conditions. The model was expressed by coupled differential equations and the radioactivity in each compartment was solved as a function of time following an acute deposition. Although DYNACON is structurally based on existing models, it was designed in order to simulate more realistic radionuclide behavior in Korean agricultural conditions and to save computation time. It was found that the radioactivity in foodstuffs depends strongly on the date of deposition. A comparative study between DYNACON and an equilibrium model showed good agreement for depositions that occur during the growing season of plants. DYNACON is going to be implemented in a Korean real-time dose assessment system FADAS. (author)
Full Text Available Land cultivation for agricultural purposes in semiarid area is usually carried out only once a year specifically during the rainy season. The condition is even worse since it is not without the risk of failure because of dry-spell or water-logging. To cope with this situation, the researchers developed a model of Rainwater Management for Agriculture Decision Supporting System (RMA-DSS. The objective of this RMA-DSS is to facilitate the decision making to build water infrastructure. Using this program it is hoped that sufficient water supply for specific crops with correct planting time can be guaranteed, which in turn will optimize harvest.

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.

Terrestrial ecosystems are threatened by climate and land management change. These changes result from complex and heterogeneous interactions of human activities and natural processes. Here, we study the potential change in pristine area in 33 global biodiversity hotspots within this century under four climate projections (representative concentration pathways) and associated population and income developments (shared socio-economic pathways). A coupled modelling framework computes the regional net expansion of crop and pasture lands as result of changes in food production and consumption. We use a biophysical crop simulation model to quantify climate change impacts on agricultural productivity, water, and nutrient emissions for alternative crop management systems in more than 100 thousand agricultural land polygons (homogeneous response units) and for each climate projection. The crop simulation model depicts detailed soil, weather, and management information and operates with a daily time step. We use time series of livestock statistics to link livestock production to feed and pasture requirements. On the food consumption side, we estimate national demand shifts in all countries by processing population and income growth projections through econometrically estimated Engel curves. Finally, we use a global agricultural sector optimization model to quantify the net change in pristine area in all biodiversity hotspots under different adaptation options. These options include full-scale global implementation of i) crop yield maximizing management without additional irrigation, ii) crop yield maximizing management with additional irrigation, iii) food yield maximizing crop mix adjustments, iv) food supply maximizing trade flow adjustments, v) healthy diets, and vi) combinations of the individual options above. Results quantify the regional potentials and limits of major agricultural producer and consumer adaptation options for the preservation of pristine areas in

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

A set of supporting tools to help take remedial decisions in case of radiological contamination of agricultural produce is being developed within the EURANOS project. The tools are created in the ArcGIS environment in the Python programming language. So far, a simple model to estimate biomass in the contaminated area has been set up. This module will make it possible to estimate additional parameters, such as activity per kg or amount of waste created, which are useful when taking decision regarding premature crops harvesting. Areas where no remedial action is required can be also identified, of course

Full Text Available Virtual business communities (VBC are virtual networks of people who share common interests and comprise online software platforms that enables the fast exchange of information, collaboration and business interactions. From 2011 to 2015, we developed a design science research to create a VBC platform for an agricultural cluster of flower growers in the South of Brazil. The goal of this platform was to help to structure and strengthen this cluster by bringing together buyers and sellers while fostering cooperation to boost cluster competitiveness and economic development in the region. However, a number of challenges surfaced during the process, which led to a failure in the VBC platform’s diffusion. We adopted a sociomaterial perspective based on the mangle of practice concept (Pickering, 1993 to investigate this failure, by analyzing the key challenges involved in developing a VBC platform in an agricultural context. As its main result, this paper reveals the mangling process during the design and application of the VBC platform and details the different instances of tuning between the participants and the technology. We observed resistance and factors that weakened cooperation and resulted in a lack of governance rules, which are key to the success of a VBC platform.

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. © 2012 The Authors.

Limnologists recently have developed an interest in quantifying benthic resource contributions to higher-level consumers. Much of this research focuses on natural lakes with very little research in reservoirs. In this study, we provide a contemporary snapshot of the food web structure of Lake Mead to evaluate the contribution of benthic resources to fish consumers. In addition, we document the available food to fishes on soft sediments and changes to the invertebrate community over 2 time periods. Benthic invertebrate food availability for fishes is greater in Las Vegas Bay than Overton Arm. Las Vegas Bay is dominated by oligochaetes, whose biomass increased with depth, while Overton Arm is dominated by chironomids, whose biomass did not change with depth. Diet and isotopic measurements indicate the fish community largely relies on benthic resources regardless of basin (Las Vegas Bay >80%; Overton Arm >92%); however, the threadfin shad likely contribute more to largemouth and striped bass production in Overton Arm versus Las Vegas Bay. A 2-time period analysis, pre and post quagga mussel establishment and during lake level declines, suggests there is no change in the density of benthic invertebrates in Boulder Basin, but there were greater abundances of select taxa in this basin by season and depth than in other basins. Given the potential of alterations as a result of the expansion of quagga mussel and the reliance of the fishery on benthic resources, future investigation of basin specific, benthic processes is recommended.

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 Agriculture is the main driving force of rural economies so there is a need to promote sustainable rural development and hence improve the living conditions of local communities. This article analyses the role of agricultural policies in reducing poverty in rural communities. Two aspects will be analysed: firstly, whether there has been a reduction in poverty in the basins analysed for the period 2006–2013; and secondly, whether that poverty reduction, to the extent that it has occurred, has been due to the agricultural policies applied. The analysis shows that the agricultural policies implemented helped to diversify and enhance agricultural production, so that a reduction in effective poverty occurred. However, these policies need to work jointly and in harmony with other economic sectors.

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.

Research was conducted at 28-30 sites within eight study areas across the United States along a gradient of nutrient enrichment/agricultural land use between 2003 and 2007. Objectives were to test the application of an agricultural intensity index (AG-Index) and compare among various invertebrate and algal metrics to determine indicators of nutrient enrichment nationally and within three regions. The agricultural index was based on total nitrogen and phosphorus input to the watershed, percent watershed agriculture, and percent riparian agriculture. Among data sources, agriculture within riparian zone showed significant differences among values generated from remote sensing or from higher resolution orthophotography; median values dropped significantly when estimated by orthophotography. Percent agriculture in the watershed consistently had lower correlations to invertebrate and algal metrics than the developed AG-Index across all regions. Percent agriculture showed fewer pairwise comparisons that were significant than the same comparisons using the AG-Index. Highest correlations to the AG-Index regionally were −0.75 for Ephemeroptera, Plecoptera, and Trichoptera richness (EPTR) and −0.70 for algae Observed/Expected (O/E), nationally the highest was −0.43 for EPTR vs. total nitrogen and −0.62 for algae O/E vs. AG-Index. Results suggest that analysis of metrics at national scale can often detect large differences in disturbance, but more detail and specificity is obtained by analyzing data at regional scales.

Drought is a major cause of crop yield loss, both in rainfed and irrigated agroecosystems. In past decades, many approaches have been developed to assess agricultural drought, usually based on the monitoring or modelling of the soil water content condition. All these indices show weaknesses when applied for a real time drought monitoring and management at the local scale, since they do not consider explicitly crops and soil properties at an adequate spatial resolution. This work describes a newly developed agricultural drought index, called Transpirative Deficit Index (D-TDI), and assesses the results of its application over a study area of about 210 km2 within the Po River Plain (northern Italy). The index is based on transforming the interannual distribution of the transpirative deficit (potential crop transpiration minus actual transpiration), calculated daily by means of a spatially distributed conceptual hydrological model and cumulated over user-selected time-steps, to a standard normal distribution (following the approach proposed by the meteorological index SPI - Standard Precipitation Index). For the application to the study area a uniform maize crop cover (maize is the most widespread crop in the area) and 22-year (1993-2014) meteorological data series were considered. Simulation results consist in maps of the index cumulated over 10-day time steps over a mesh with cells of 250 m. A correlation analysis was carried out (1) to study the characteristics and the memory of D-TDI and to assess its intra- and inter-annual variability, (2) to assess the response of the agricultural drought (i.e., the information provided by D-TDI) to the meteorological drought computed through the SPI over different temporal steps. The D-TDI is positively auto-correlated with a persistence of 30 days, and positively cross-correlated to the SPI with a persistence of 40 days, demonstrating that D-TDI responds to meteorological forcing. Correlation analyses demonstrate that soils

Today's modern precision agriculture applications have a huge demand for data with high spatial and temporal resolution. This leads to the need of unmanned aerial vehicles (UAV) as sensor platforms providing both, easy use and a high area coverage. This study shows the successful development of a prototype hybrid UAV for practical applications in precision agriculture. The UAV consists of an off-the-shelf fixed-wing fuselage, which has been enhanced with multi-rotor functionality. It was programmed to perform pre-defined waypoint missions completely autonomously, including vertical take-off, horizontal flight, and vertical landing. The UAV was tested for its return-to-home (RTH) accuracy, power consumption and general flight performance at different wind speeds. The RTH accuracy was 43.7 cm in average, with a root-mean-square error of 39.9 cm. The power consumption raised with an increase in wind speed. An extrapolation of the analysed power consumption to conditions without wind resulted in an estimated 40 km travel range, when we assumed a 25 % safety margin of remaining battery capacity. This translates to a maximal area coverage of 300 ha for a scenario with 18 m/s airspeed, 50 minutes flight time, 120 m AGL altitude, and a desired 70 % of image side-lap and 85 % forward-lap. The ground sample distance with an in-built RGB camera was 3.5 cm, which we consider sufficient for farm-scale mapping missions for most precision agriculture applications.

Full Text Available Ultramafic soils are typically enriched in nickel (Ni, chromium (Cr, and cobalt (Co and deficient in essential nutrients, making them unattractive for traditional agriculture. Implementing agromining systems in ultramafic agricultural soils represent an ecological option for the sustainable management and re-valorisation of these low-productivity landscapes. These novel agroecosystems cultivate Ni-hyperaccumulating plants which are able to bioaccumulate this metal in their aerial plant parts; harvested biomass can be incinerated to produce Ni-enriched ash or “bio-ore” from which Ni metal, Ni ecocatalysts or pure Ni salts can be recovered. Nickel hyperaccumulation has been documented in ~450 species, and in temperate latitudes these mainly belong to the family Brassicaceae and particularly to the genus Odontarrhena (syn. Alyssum pro parte. Agromining allows for sustainable metal recovery without causing the environmental impacts associated with conventional mining activities, and at the same time, can improve soil fertility and quality and provide essential ecosystem services. Parallel reductions in Ni phytotoxicity over time would also permit cultivation of conventional agricultural crops. Field studies in Europe have been restricted to Mediterranean areas and these only evaluated the Ni-hyperaccumulator Odontarrhena muralis s.l. Two recent EU projects (Agronickel and LIFE-Agromine have established a network of agromining field sites in ultramafic regions with different edapho-climatic characteristics across Albania, Austria, Greece and Spain. Soil and crop management practices are being developed so as to optimize the Ni agromining process; field studies are evaluating the potential benefits of fertilization regimes, crop selection and cropping patterns, and bioaugmentation with plant-associated microorganisms. Hydrometallurgical processes are being up-scaled to produce nickel compounds and energy from hyperaccumulator biomass. Exploratory

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.

Full Text Available Coordination optimization of directional overcurrent relays (DOCRs is an important part of an efficient distribution system. This optimization problem involves obtaining the time dial setting (TDS and pickup current (Ip values of each DOCR. The optimal results should have the shortest primary relay operating time for all fault lines. Recently, the particle swarm optimization (PSO algorithm has been considered an effective tool for linear/nonlinear optimization problems with application in the protection and coordination of power systems. With a limited runtime period, the conventional PSO considers the optimal solution as the final solution, and an early convergence of PSO results in decreased overall performance and an increase in the risk of mistaking local optima for global optima. Therefore, this study proposes a new hybrid Nelder-Mead simplex search method and particle swarm optimization (proposed NM-PSO algorithm to solve the DOCR coordination optimization problem. PSO is the main optimizer, and the Nelder-Mead simplex search method is used to improve the efficiency of PSO due to its potential for rapid convergence. To validate the proposal, this study compared the performance of the proposed algorithm with that of PSO and original NM-PSO. The findings demonstrate the outstanding performance of the proposed NM-PSO in terms of computation speed, rate of convergence, and feasibility.

Precise lake bathymetry (i.e., elevation/contour) mapping is essential for optimal decision making in water resources management. Although the advancement of remote sensing has made it possible to monitor global reservoirs from space, most of the existing studies focus on estimating the elevation, area, and storage of reservoirs—and not on estimating the bathymetry. This limitation is attributed to the low spatial resolution of satellite altimeters. With the significant enhancement of ICESat-2—the Ice, Cloud & Land Elevation Satellite #2, which is scheduled to launch in 2018—producing satellite-based bathymetry becomes feasible. Here we present a pilot study for deriving the bathymetry of Lake Mead by combining Landsat area estimations with airborne elevation data using the prototype of ICESat-2—the Multiple Altimeter Beam Experimental Lidar (MABEL). First, an ISODATA classifier was adopted to extract the lake area from Landsat images during the period from 1982 to 2017. Then the lake area classifications were paired with MABEL elevations to establish an Area-Elevation (AE) relationship, which in turn was applied to the classification contour map to obtain the bathymetry. Finally, the Lake Mead bathymetry image was embedded onto the Shuttle Radar Topography Mission (SRTM) Digital Elevation Model (DEM), to replace the existing constant values. Validation against sediment survey data indicates that the bathymetry derived from this study is reliable. This algorithm has the potential for generating global lake bathymetry when ICESat-2 data become available after next year's launch.
Full Text Available 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.

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.

Policy initiatives to reduce greenhouse gas emissions (GHG) have promoted the development of agricultural management protocols to increase SOC storage and reduce GHG emissions. We review approaches for quantifying N2O flux from agricultural landscapes. We summarize the temporal and spatial extent of observations across representative soil classes, climate zones, cropping systems, and management scenarios. We review applications of simulation and empirical modeling approaches and compare validation outcomes across modeling tools. Subsequently, we review current model application in agricultural management protocols. In particular, we compare approaches adapted for compliance with the California Global Warming Solutions Act, the Alberta Climate Change and Emissions Management Act, and by the American Carbon Registry. In the absence of regional data to drive model development, policies that require GHG quantification often use simple empirical models based on highly aggregated data of N2O flux as a function of applied N - Tier 1 models according to IPCC categorization. As participants in development of protocols that could be used in carbon offset markets, we observed that stakeholders outside of the biogeochemistry community favored outcomes from simulation modeling (Tier 3) rather than empirical modeling (Tier 2). In contrast, scientific advisors were more accepting of outcomes based on statistical approaches that rely on local observations, and their views sometimes swayed policy practitioners over the course of policy development. Both Tier 2 and Tier 3 approaches have been implemented in current policy development, and it is important that the strengths and limitations of both approaches, in the face of available data, be well-understood by those drafting and adopting policies and protocols. The reliability of all models is contingent on sufficient observations for model development and validation. Simulation models applied without site-calibration generally

In spite of the strides made globally in reducing hunger, the problems of micronutrient deficiencies and coexisting obesity and related cardiovascular and degenerative diseases constitute a formidable challenge for the future. Attempts to reverse this trend with single-nutrient intervention strategies have met with limited success, resulting in renewed calls for food-based approaches. The deployment of agricultural biodiversity is an approach that entails greater use of local biodiversity to ensure dietary diversity. To outline a new strategy proposed by the International Plant Genetic Resources Institute (IPGRI) that employs agricultural biodiversity as the primary resource for food security and health. The authors carried out a meta-analysis to review and assemble existing information on the nutritional and healthful properties of traditional foods based on a diverse set of case studies and food composition and nutritional analysis studies. The methods highlight particular examples of foods where analysis of nutrient and non-nutrient composition reveals important traits to address the growing problems of malnutrition associated with the rise of chronic diseases. Finally, the authors analyze social, economic, and cultural changes that undermine the healthful components of traditional diets. Based on this multidisciplinary and comparative approach, the authors suggest a holistic food-based approach that combines research to assess and document nutritional and healthful properties of traditional foods, investigating options in which nutritionally valuable traditional foods can contribute to better livelihoods, and ways that awareness and promotional campaigns can identify healthful components of traditional diets that fit the needs of urban and market-oriented consumers. There is an urgent need for agricultural research centers, national agricultural research systems, universities, and community-based organizations to work together under a shared policy framework
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

We present an assessment of biofuel use and agricultural field burning in the developing world. We used information from government statistics, energy assessments from the World Bank, and many technical reports, as well as from discussions with experts in agronomy, forestry, and agro-industries. We estimate that 2060 Tg biomass fuel was used in the developing world in 1985; of this, 66% was burned in Asia, and 21% and 13% in Africa and Latin America, respectively. Agricultural waste supplies about 33% of total biofuel use, providing 39%, 29%, and 13% of biofuel use in Asia, Latin America, and Africa, and 41% and 51% of the biofuel use in India and China. We find that 400 Tg of crop residues are burned in the fields, with the fraction of available residue burned in 1985 ranging from 1% in China, 16-30% in the Middle East and India, to about 70% in Indonesia; in Africa about 1% residue is burned in the fields of the northern drylands, but up to 50% in the humid tropics. We distributed this biomass burning on a spatial grid with resolution of 1° × 1°, and applied emission factors to the amount of dry matter burned to give maps of trace gas emissions in the developing world. The emissions of CO from biofuel use in the developing world, 156 Tg, are about 50% of the estimated global CO emissions from fossil fuel use and industry. The emission of 0.9 Pg C (as CO2) from burning of biofuels and field residues together is small, but nonnegligible when compared with the emissions of CO2 from fossil fuel use and industry, 5.3 Pg C. The biomass burning source of 10 Tg/yr for CH4 and 2.2 Tg N/yr of NOx are relatively small when compared with total CH4 and NOx sources; this source of NOx may be important on a regional basis.

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

This document is an output from the OECD Development and Climate Change project, an activity jointly overseen by the EPOC Working Party on Global and Structural Policies (WPGSP), and the DAC Network on Environment and Development Co-operation (ENVIRONET). 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 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.

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.

This study explores the water and agricultural tradeoffs linked to three different rural development scenarios in the Cega-Eresma-Adaja basin (CEA) in Central Spain. Agriculture is a key socioeconomic activity in CEA, and nearly 44% of the basin is devoted to croplands and pastures. Irrigated agriculture accounts for 12% of the cropland area and is currently using over 84% of available water resources. To define the three scenarios for CEA, we conducted a workshop with local stakeholders to infer how contrasting evolutions of EU agricultural, water and environmental policies could affect the local land use and agricultural management using participatory mapping techniques. The three scenarios reflect 1) a business as usual (BAU) rural development; 2) a land sharing strategy (LSH); and 3) a land sparing (LSP) situation. The integrated Soil Water Assessment Tool (SWAT) was used to model the changes in water use (hm^3/year) and agricultural productivity (ton/year) under each scenario. To account for changes in agricultural land use and management, the model integrates a large set of agricultural patterns obtained from combining high resolution remote sensing images (20m x 20m) for the years 2011-2015, agricultural productivity from survey by municipality and land use information obtained from the national map SIOSE2011 (1:50.000). Model calibration and sensitivity analysis were performed using SWAT-CUP/SUFI2 The period of the years 2005 to 2008 were used for parameter calibration and validation period extending between 2009 and 2014. The predicted daily streamflow presents a correlation coefficient of 0.76 and a NS coefficient of 0.81. The preliminary results reveal that under a BAU and a LSP scenario agricultural production and water demand will increase significantly (>25%) despite the improvements in water use efficiency and agricultural productivity. Under these scenarios, allocated water is likely to exceed the natural renewable water resources compromising the

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.

Tottori University and Japan Atomic Energy Agency started a joint study to develop an environmental remediation technique for agricultural soil. Nine plants were water-cultured and examined for screening. A few were selected as candidates for demonstrations in fields. Preselected plants were mainly halophytes that can specifically absorb more Na than K, and others like sunflower demonstrated for domestic large-scale tests. Easily cultivated and harvested plants without harmful effect on new agriculture were also considered. Seedings prepared were first grown for a certain term. Additive-free, 133 Cs and 88 Sr groups, which are both stable isotopes, were then made. Cs (CsCl) and Sr (SrCl 2 ·6H 2 O) contents in cultures were 1.6836 mg/L (0.01 mM) and 266.62 mg/L (1 mM), respectively. Stems, leaves and roots were harvested, in principle, two weeks after the addition, to measure K, Ca, Mg, Sr and Cs concentrations in them. Considering the examination period, a content rate (i.e. element amount per dry sample weight) was regarded as an index. It was concluded that New Zealand spinach and ice plant were most adequate for removing contaminants from surface soil. The two accumulate Cs and Sr mostly in the shoots, are prostrate, and spread the roots shallowly. For valid application, growth-phase dependences of absorption and distribution, growth property and root distribution should be elucidated. Plants that meet the present purpose are ones that specifically absorb object substances, or that show normal absorption but high removal rate per area due to the large bulk size. The latter view also needs to be evaluated when the field test is conducted, since developing stages of the plants used in the present work were not correspondent. Finally, the application study plan was developed based on the screening test results. (author)

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

The development of endophyte inoculants for agricultural crops has been bedevilled by the twin problems of a lack of reliability and consistency, with a consequent lack of belief among end users in the efficacy of such treatments. We have developed a successful research pipeline for the production of a reliable, consistent and environmentally targeted fungal endophyte seed-delivered inoculant for barley cultivars. Our approach was developed de novo from an initial concept to source candidate endophyte inoculants from a wild relative of barley, Hordeum murinum (wall barley). A careful screening and selection procedure and extensive controlled environment testing of fungal endophyte strains, followed by multi-year field trials has resulted in the validation of an endophyte consortium suitable for barley crops grown on relatively dry sites. Our approach can be adapted for any crop or environment, provided that the set of first principles we have developed is followed. Here, we report how we developed the successful pipeline for the production of an economically viable fungal endophyte inoculant for barley cultivars.

The utilisation of Social Impact Assessment (SIA) in Iran is analysed in terms of its policy context and its application in practice. Five case studies where SIA was employed in conjunction with Environmental Impact Assessments (EIA) for agricultural development projects are evaluated. In addition, the performance of the policy context is assessed. This research revealed that there are legal and institutional constraints to the effective functioning of SIA in Iran, and that there are deficiencies in the operating guidelines. There were serious problems associated with the way SIA was undertaken in all five case studies. Recommendations to improve the policy framework for the conduct of SIA are made. The recommendations advocate for a higher profile of SIA within legislation, for social issues to have greater emphasis in official guidelines for the conduct of EIA and SIA, and for a range of measures to increase the professionalism of SIA practice.

The aim of this work is to develop a method for gamma ray spectrum deconvolution from NaI(Tl) detector. Deconvolution programs edited with Matlab 7.6 using Nelder-Mead method were developed to determine multiplet shape parameters. The simulation parameters were: centroid distance/FWHM ratio, Signal/Continuum ratio and counting rate. The test using synthetic spectrum was built with 3σ uncertainty. The tests gave suitable results for centroid distance/FWHM ratio≥2, Signal/Continuum ratio ≥2 and counting level 100 counts. The technique was applied to measure the activity of soils and rocks samples from the Anosy region. The rock activity varies from (140±8) Bq.kg -1 to (190±17)Bq.kg -1 for potassium-40; from (343±7)Bq.Kg -1 to (881±6)Bq.kg -1 for thorium-213 and from (100±3)Bq.kg -1 to (164 ±4) Bq.kg -1 for uranium-238. The soil activity varies from (148±1) Bq.kg -1 to (652±31)Bq.kg -1 for potassium-40; from (1100±11)Bq.kg -1 to (5700 ± 40)Bq.kg -1 for thorium-232 and from (190 ±2) Bq.kg -1 to (779 ±15) Bq -1 for uranium -238. Among 11 samples, the activity value discrepancies compared to high resolution HPGe detector varies from 0.62% to 42.86%. The fitting residuals are between -20% and +20%. The Figure of Merit values are around 5%. These results show that the method developed is reliable for such activity range and the convergence is good. So, NaI(Tl) detector combined with deconvolution method developed may replace HPGe detector within an acceptable limit, if the identification of each nuclides in the radioactive series is not required [fr
Full Text Available There are a large number of farms in Serbia, which survived with a little capital and labor, and today one of the perspectives they see in the integration with the rural tourism. Tourism development is an incentive for the introduction of improvements in agricultural production, processing and supply of food, as well as the introduction of modern standards that are difficult to apply on small farms because of the high costs of their implementation. Rural tourism in Serbia is not at a satisfactory level of development, although there are all preconditions for its intensive development. Due to unfavorable political and economic position of Serbia, rural tourism has not encountered the support of its favorable development among its competitors. The authors have tried to point out a study for the attitude of the hosts as a service providers on the current status and problems faced in providing services in rural tourism. Investigated in 15 municipalities in Vojvodina (Northern Serbia, Southwestern Serbia and Southeastern Serbia, and in a total of 46 owners of small farms. Using the tests methods questionnaires and processing in SPSS, version 19.0, and analysis of the data, authors led to the confirmation of certain hypotheses of which started in the investigation.
Full Text Available The problem of increasing the economic efficiency of resource use in agricultural production is very important. Its solution directly depends on the economic security of the country and its constant supply with agricultural products.There are three basic factors in agricultural production: nature (land, labour and capital, which have differentmeasure units. Comparability is necessary to express the value of the integral potential that gives the possibility totake into account the main resources involved in producing and obtaining results from the agricultural sector.
In a world facing the dilemmas posed by exponential population growth and changing climates, nuclear technology offers possible avenues to solve production problems, protect soil and water resources and conserve biodiversity, which, in turn, means increased hope for global food security. Application of nuclear technology has a proven record in increasing agricultural production. Higher and more reliable yields not only improve farmers' livelihoods, they mean better quality and safer food for consumers. The methods used vary: isotope measurements identify and trace the efficiency of crop inputs such as water and fertilizer and of animal feeds; gamma rays sterillize male insects so that when they are returned to the wild they are unable to produce progeny; irradiation stops the growth of pests and expands the shelf life of grains, spices and processed foods; radiation induced mutation speeds up natural genetic changes in crops to support plant breeders; and genetic markers expedite the identification of animal diseases thereby allowing treatment to begin sooner. All of these methods, plus a host of others that come under the heading of nuclear technology, are invaluable tools for agriculture and food production. For almost five decades, the IAEA, together with its partner the FAO, guided development of new nuclear based methodologies, requested by its Member States and facilitated their adaptation, adoption and application. A harbinger of the United Nation's Delivering as One, the Joint FAO/IAEA Division stands as the United Nations' system's only joint venture. It also operates its own agriculture and biotechnology laboratories in Seibersdorf where technical services, R and D and laboratory training activities are conducted in support of the development and transfer of new technologies and their adaptation to local needs and environments.

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

Full Text Available This paper aims to describe a tourism industry which needs a variety of tourism products with an implication on the emergence of various forms of business opportunities with large, medium and small scales. The presence of a variety of tourists’ needs have caused a variety of tourism products too. Agriculture, animal husbandry, and handicraft which are needed by tourists are sectors which need a lot of workers as producers, distributors and sellers. In the study reported in the present paper is shown that the agricultural products of Bali cannot only be used as agro-tourism, but whose products can also be processed to become a variety of handicrafts. Similarly, animal husbandry which Balinese community people have focused on produces products that can be offered in a culinary tourism in which they are processed by using Balinese ingredients and offered in an appropriate wrapping which suits the market needs, while the specificity of Balinese culture has been able to produce a variety of forms of handicrafts the local and foreign tourists love. Through developments in the three sectors above, if the people can focus their attention on them and if the government can accommodate it that will be able to be used as an alternative solution to the national economy. Although in their actions they can only serve as sellers, as what has been the focus of street vendors, they actually act as safety valve of the government in overcoming unemployment problems and economic problems for themselves and their families. For this reason, it is expected that the government gives them a more conducive condition for the improvement of economy to be made starting from the family level, as part of the state of Indonesia.

A large proportion of meteorological stations in mainland China are located in or near either urban or agricultural lands that were established throughout the period of rapid urbanization and agricultural development (1961-2006). The extent of the impacts of urbanization and agricultural development on observed air temperature changes across different climate regions remains elusive. This study evaluates the surface air temperature trends observed by 598 meteorological stations in relation to the urbanization and agricultural development over the arid northwest, semi-arid intermediate, and humid southeast regions of mainland China based on linear regressions of temperature trends on the fractions of urban and cultivated land within a 3-km radius of the stations. In all three regions, the stations surrounded by large urban land tend to experience rapid warming, especially at minimum temperature. This dependence is particularly significant in the southeast region, which experiences the most intense urbanization. In the northwest and intermediate regions, stations surrounded by large cultivated land encounter less warming during the main growing season, especially at the maximum temperature changes. These findings suggest that the observed surface warming has been affected by urbanization and agricultural development represented by urban and cultivated land fractions around stations in with land cover changes in their proximity and should thus be considered when analyzing regional temperature changes in mainland China.

Full Text Available We look at our article on a relational communicationapproach. In this sense, we seek to understandthe communication process from a praxeologicalmodel as elaborated by Louis Quéré (1991,rather than an epistemological model, seized in earlierformulations about the communicative practice.With pragmatism as a guideline of our argument,we are interested in understand and approach thenotions of self and experience as discussed by JohnDewey (1896, 1980, 2010 and George Herbert Mead(1934. Both concepts seem appropriate to thinkabout communication. Our purpose is then to seeto what extent we can reasonably argue that the selfis in constant experience and the implications thatpermeate this conceptual relationship.
