    Productivities under low input or subsistence agriculture are strongly dependent on nutrient supply from soil organic matter mineralization (SOM). Few results are available and they indicate declines in soil fertility under this agricultural system, particularly in SOM levels. In an attempt to understand the nature and extent of these declines we selected ten sites having cultivated areas adjacent with areas under native vegetation at the same slope position, in the states of Pernambuco and Paraiba. Based on the management history, in situ observations and {sup 137} Cs concentrations to evaluate soil erosion, the areas were divided in four groups having different levels of soil use intensity: Undisturbed Dry Forest (UDF), Disturbed Dry Forest (DDF), Preserved-Cultivated (PC) and Degraded-Cultivated (DC). In the first part of this work we quantified total organic C, N and P, in addition to {sup 137} Cs concentrations, under the assumption that changes in organic nutrient contents among land use groups would be greater than the within group variability, thus enabling inferences at a regional scale. Concentrations of C and N in DC were 50% smaller (P<0.05) than those in UDF. Of these losses, 43% were attributed to erosion processes while 57% were related to SOM mineralization. The Po/Pi ratio under UDF was 1.47 and decreased to o.82 in PC and DC (P<0.05). The effects of changes in land use were greater when considering the 0-7.5 cm layer rather than the 0-15 cm layer. Interrelationships between C and P in the dry forest areas suggested that P availability and water controlled C accumulation in these soils. In the second part of this work two experiments were conducted. The first one included a preliminary phase, comparing four methods in their capacity to detect changes in soil organic matter quality. Eighty samples that maximized the variability in C content of the whole set (n=160), were analyzed for: C in the light SOM fraction (density < 1 kg dm{sup -3}) (C-lf); C

    Full Text Available Como en otras regiones de México, los campesinos de la Mixteca Alta (Estado de Oaxaca, han dejado de depender de la agricultura ya que reciben remesas de sus parientes emigrados en los Estados Unidos. El fenómeno de la migración, presente en esta región desde hace varias décadas, ha aumentado exponencialmente en los últimos diez años. La mayoría de los adultos jóvenes dejan sus hogares, los cuales están ahora compuestos de madres e hijos o abuelos y nietos. Con el dinero de las remesas el equipo de las cocinas se ha modernizado y se han incorporado cambios técnicos en las preparaciones culinarias; se come más carne y alimentos procesados y menos verduras silvestres. Al mismo tiempo, varios programas de desarrollo impulsados por el gobierno están provocando cambios profundos sobre la economía familiar, la organización social y el papel de las mujeres. Ahora, el statuseconómico de las familias ya no depende de la extensión de sus tierras, sino del número de sus miembros trabajando en “el Norte”. No obstante, el rico patrimonio culinario de esta población sigue vivo, particularmente para las comidas festivas.Como em outras regiões do México, os indígenas da Mixteca Alta (Estado de Oaxaca quase já não vivem da agricultura, mas das remessas dos seus parentes emigrados que moram nos Estados Unidos.

    The work had the purpose of checking the agricultural development processing, under the energetic view. The analysis elaborated through homogeneous micro-regions, is provided by agrocatle census from IBGE and SEADE from 1970 to 1985. The intensive use of chemical fertilizers in the seventies was encouraged by the facilities of the rural credit. The reduction of these facilities, made the use of organic fertilizers raise where, in 1985, the mature stage, more than 95% of the properties were using it. The diesel oil was the unique energetic source that showed a raise in numbers of properties as in consumed volume, showing during these period a raise of 632,59%, in Jau region, followed by gas and alcohol, representing 80% of the consumed energy. There was an electrification in the country, and in 1985, 60% of the properties were electrified. The residential was the biggest responsible for the demand of energy in the agricultural micro-regions and, for the agro-industrialized ones, it was more used in production. The period is characterized by raising the numbers of 100 HP power higher in all regions, mostly in the agro-industrialized ones, showing its operational efficiency in the field. The rough transformation that was inflicted to the agriculture, made the mechanisms unable for the agriculture development in a harmonic and proper way, making it self an appendix to the capitalist system, incorporating its way manage, becoming highly dependent on the energetic national headquarters.

    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 objective of this work was to evaluate in millimetric scale changes in soil bulk density and porosity, using the gamma-ray computed tomography in soil samples with disturbed structure due to wetting and drying (W-D) cycles. Soil samples with 98.1 cm{sup 3} were sieved using a 2 mm mesh and homogeneously packed in PVC cylinders. Soil samples were submitted to 1, 2, and 3 W-D cycles. Control samples were not submitted to W-D cycles. After repetitions of W-D cycles, soil sample porosity decreased and soil layers became denser. Computed tomography allowed a continuous analysis of soil bulk density and also soil porosity along millimetric (0.08 cm) layers, what cannot be provided by traditional methods used in soil physics.

Além disso, é também reconhecida pela sua qualidade de sua cozinha, vista como gourmet. Entretanto, a alta gastronomia é apenas uma parte da vasta diversidade de culinárias que se oferecem nessa cidade-porto, um resultado das profundas mudanças sociais ali transcorridas nas últimas três décadas. O texto oferece uma breve explanação da introdução e evolução de alguns usos alimentares em Puerto Vallarta, expondo também uma articulação com o contexto local, analisando o abastecimento, a composição alimentar e seus ritmos. Nesse sentido, questiona-se a existência de um modelo alimentar local justaposto às fortes influências exógenas e que teria poucos vínculos com uma possível identidade cultural da população local.Puerto Vallarta, located on the Mexican Pacific coast, is now a prestigious tourist destination. It is also considered a venue for gourmet cooks, due to the elaborate variety of gastronomy available. Nevertheless, what meets the eye is only part of a motley crowd of culinary possibilities that emerge simultaneously in this port, which in turn are the result of the giddy social change of the last three decades. The following text gives a brief explanation of the historic evolution of Puerto Vallarta regarding the introduction of different culinary traditions; it explores the perceptions of local inhabitants of these gastronomic innovations; these perceptions are duly related to a supposed local cultural ethos; and finally it proposes that the juxtaposition of what is on offer gastronomically is an extension of certain ‘food models’ and the development of a new socio-cultural identity.Situado en la costa meridional del Pacífico mexicano, Puerto Vallarta es un sitio turístico prestigiado, y es también considerado un destino de cocina gourmet.

    The aim of this paper is to show that the gains from the use of ethanol as fuel in agricultural aviation may be even greater to if the aircraft engine is specially designed for that purpose, and to obtain a truly 'green' engine, neutral regarding carbon emissions. Using computational tools, development methods and project management, the engine can be fully developed to be used specifically as an agricultural aircraft propellant operating with ethanol. In Brazil, the current fleet of agricultural airplanes has around 1400 aircrafts and almost all operating with AvGas. There is already in Brazil an aircraft, manufactured by a Brazilian aircraft manufacturer, that uses a conversion kit for the original engine to use ethanol as fuel. The use of ethanol has great technical and economic feasibility when compared to AvGas, even with the low efficiency of the current application. Operational improvement and gains with cost reduction can be already observed. However, with a specific design those gains could be with the low efficiency of the current application. Operational improvement and gains with cost reduction can be already observed. However, with a specific design those gains could be more expressive due to increased engine fuel efficiency and power.

    The human interference in the environment and the consequent climate change is today a consensus. The climate change can be local, regional and global. The global climate change is mainly caused by the greenhouse gases, and consequently the climate change intervenes in the environment. The interference cycle emerges in several forms and results in several consequences. However, the Global Warming has certainly the most import global impact. The main cause of the increase in the temperature (Greenhouse Effect) is the intensive use of the fossil fuels. Thus, to minimize the climatic changes actions are necessary to reduce, to substitute and to use with more efficient the fossil fuels. Looking at the past, the old agriculturists may have released greenhouse gases since thousand years ago, thus, modifying slowly but in significant form the earth climate much before the Industrial Age. If this theory is confirmed, its consequences would be decisive for the man history in the planet. For example, in parts of the North America and Europe the current temperatures could be even four Celsius degrees smaller. This change in temperature is enough to hinder agricultural used of these regions and consequently to diminish the human development. The main focus of this work is to perform a retrospective in some of civilizations who collapse due to environmental problems and make a historical description of the human activities (agriculture and livestock) since the primordium of the man up to the Industrial Age, aiming at the man interference on the natural dynamics of the global climate and the environment. This work will show through data comparisons and inferences that the gases emissions from these activities had a significant magnitude comparatively by the emissions after the Industrial Age. It is also demonstrated that the climate and environment interference was inevitable because the human evolution was caused by these activities. Another important point of this work is to

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

We emphasize the overview of modern trends in settlement development and land use and point out the processes that do not correspond with planned goals. Through simulating developmental consequences in several typical areas of different developmental possibilities and by referring to spontaneous processes, we are discussing the overgrowth of agricultural land and its transformation into built up space. At the end we offer a possible direction for future countryside development with the help of a simulation model.

Orientando-se por autores que propoem a operacionalização do conceito de competencias nas organizacões, construiram-se quadros de referencias para as celulas da organização de modo que houvesse mais transparencia e consistencia nas ações de gestão, e isso representa um grave problema das pequenas empresas. Os quadros são compostos de atributos como missão, atribuições, contribuições, indicadores de resultados e competencias, todos definidos com base nas estrategias e nos objetivos almejados pela organização. Ante a proposta de não apenas explorar e descrever, mas tambem de mudar, o estudo utilizou como orientação metodologica a pesquisa-ação. Esse metodo não se limita apenas a descrever uma situação, mas tambem pretende desencadear, em certos casos, mudancas no seio da coletividade envolvida. O proprio processo de busca e os resultados alcancados demonstraram, a principio, que a estruturação de uma empresa por competencias gera turbulencias iniciais, principalmente pela radicalidade da mudança (neste caso e pelas particularidades do conceito. A nova estrutura tem provocado mudanças culturais, sobretudo na açao dos gestores que tem agora informações claras sobre as atribuições e exigencias cabiveis a cada celula, bem como de seus respectivos indicadores de desempenho.

  3. Availability of metals in samples of phosphogypsum and phosphate fertilizers used in agriculture; Disponibilidade de metais em amostras de fosfogesso e fertilizantes fosfatados utilizados na agricultura

    The Brazilian phosphate fertilizer is obtained by wet reaction of the igneous phosphate rock with concentrated sulphuric acid, giving as final product, phosphoric acid, and dehydrated calcium sulphate (phosphogypsum) as by-product. Part of this phosphogypsum is stored in stacks at open air and part has been used in agriculture, as soil amendment. To assure a safe utilization of phosphogypsum it is important to determine the levels of impurities, particularly of metals, present in phosphogypsum. In this paper, the concentration of metals (As, Ba, Cd, Cr, Co, Cu, Hg, Ni, Pb, Se, Zn and rare earth elements) present in Brazilian phosphogypsum and also in single super phosphate (SSP), triple super phosphate (TSP), monoammonium phosphate (MAP) and diammonium phosphate (DAP) were determined. The metals Cd, Cu, Ni, Pb and Zn were determined following the procedure 'EPA 3052'. The same elements, As and Se were also determined following the procedure 'EPA 3050B', recommended by Ministerio da Agricultura, Pecuaria e Abastecimento (MAPA). All these metals are controlled by environmental and agriculture regulation institutes in Brazil. The concentrations obtained for the metals analyzed by using the two procedures were different. Ba, Co, Cr and rare earth elements were determined by neutron activation analysis. In order to evaluate the availability of these metals As, Cd, Cr, Co, Cu, Ni, Pb, Se and Zn to the environment, the content of the same elements were determined following a procedure established by the EC (European Community), which includes an initial attack of the samples with EDTA-NH{sub 4} 0.05M, at pH 7.0. In all these cases, phosphogypsum presented metals concentration lower than the phosphate fertilizers, and the results are below the limits adopted by MAPA and Companhia Ambiental do Estado de Sao Paulo (CETESB). The results obtained using the methodology with mild attack show that the metals are not available to the environment, giving

    The rate of generation of phosphogypsum is approximately 4.8 tons for each ton of phosphoric acid produced. The annual world production can be estimated at 150 million of tons. It is classified as NORM (Naturally Occurring Radioactive Material), in other words, it is a solid waste that contains radioactive elements of natural occurrence from the source rock. The large amount of phosphogypsum produced has been attracting attention of radiological protection institutions and environmental protection agencies in the world, given its high potential for contamination of the environment. In Brazil, this material has been used for several decades, especially for agricultural purposes. In this case, the phosphogypsum is used as a source of calcium and sulfur, as conditioner, and for correction of subsurface soil saturated with sodium, potassium and aluminum. Due to the presence of radionuclides in phosphogypsum, it is necessary to understand the mechanisms for transferring of natural radionuclides in the system soil/plant and to evaluate if the use of phosphogypsum in soil contributes to increased exposition of humans to the natural radioactivity. Experiments were accomplished in a greenhouse with lettuce cultivation in two types of soil (sandy and loamy) fertilized with four different amounts of of phosphogypsum. Samples of phosphogypsum, soil, lettuce and drainage water were analyzed being determined the radionuclides of interest ({sup 238}U, {sup 232}Th, {sup 226}Ra, {sup 228}Ra, {sup 2}'1'0Pb and {sup 210}Po). {sup 238}U and {sup 232}Th have been carried out by neutron activation analysis, Ra, Ra and Pb by gamma spectrometry and Po by alpha spectrometry techniques. Finally, Transfer Factor of soil-plant was calculated and the annual contribution to the effective dose committed due to the ingestion of lettuces of the experiment. Analyses of chemical, physical and mineralogical characterization of soil and phosphogypsum samples were also accomplished. The

    Full Text Available The article deals with the afforestation of agricultural land in the rural regions of Poland's eastern borderland. It presents changes in the area and dynamics of afforestation there and the spatial distribution of its intensity. Also identified are the determinants of farmland af-forestation. Special attention is paid to afforestation carried out on private land. The research covered three borderland provinces (Podlasie, Lublin and Subcarpathia that form the east-ern boundary of the European Union. The years studied were 1996-2009, i.e. a period in which fundamental changes took place in farmland afforestation. The research showed that in the study area afforestation was largely carried out on private land, where it covered 26.7 thous. ha between 1996 and 2009. In each of the provinces under analysis the process of af-forestation of private farmland followed a similar pattern, but differed in dynamics. As in the entire country, in the rural eastern borderland one can observe an increase in the area of private land afforestation until 2003, its marked regression in 2004, another slight jump in 2005 and 2006, and another drop since 2007. The intensity of afforestation was not even; in the years under analysis it showed wide differences. Lower intensity of private farmland af-forestation was recorded in 1996-2001, at 3.4 ha per 1000 ha AL, than in 2002-2009, when the figure was 3.9 ha/1000 ha AL. But the intensity of farmland afforestation after 2001 kept declining with the changing peri-ods of afforestation co-funding.

    In recent years, the quantity of agricultural waste has been rising rapidly all over the world. As a result, the environmental problems and negative impacts of agricultural waste are drawn more and more attention. Therefore, there is a need to adopt proper approaches to reduce and reuse agricultural waste. This review presented about 200 literatures published in 2015 relating to the topic of agricultural waste. The review examined research on agricultural waste in 2015 from the following four aspects: the characterization, reuse, treatment, and management. Researchers highlighted the importance to reuse agricultural waste and investigated the potential to utilize it as biofertilizers, cultivation material, soil amendments, adsorbent, material, energy recycling, enzyme and catalyst etc. The treatment of agricultural waste included carbonization, biodegradation, composting hydrolysis and pyrolysis. Moreover, this review analyzed the differences of the research progress in 2015 from 2014. It may help to reveal the new findings and new trends in this field in 2015 comparing to 2014.

  14. Nuclear techniques in agriculture

    International Nuclear Information System (INIS)

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

    Full Text Available In this study, agricultural enterprises in Turhal, Tokat were grouped based on their degree of success, their structural characteristics have been identified and their outcomes of activities discussed. The objective of the study was to determine the aspects that render successful agricultural enterprises different from other agricultural enterprises. The point to be achieved through the study is to assist agricultural enterprises with a more effective utilization of existing means in order to help them to develop. Data has been collected from 71 agricultural enterprises, which have been determined by Neyman's Method that is a stratified sampling method, via questionnaires. The Criterion of Agricultural Income Per Enterprise Land Decar has been applied for the classification of the enterprises according to their level of success. When the agricultural income was sufficiently examined in the enterprises, moderate successful and unsuccessful enterprises cannot obtain agricultural income to meet family labor force cost. Their agricultural level is quite below the sum of the family labour wage equivalent and the real interest of the equivalent capital. Therefore, the agricultural income of the examined enterprises is considered insufficient. The rate of the net product to the active capital is 3.45% in successful enterprises, 0.57% in those with moderate success, and for the unsuccessful ones, it has a negative value of -2.22%. This ratio for successful enterprises is close to 5%.

    Full Text Available Forage sorghum can be grown in areas presenting dry and hot environmental situations where the yield of other grasses can often be uneconomical. The objective of this study was to analyze the operating performance of agricultural machines in the deployment of sorghum forage in four tillage systems, as follows: no-tillage system, disk harrow + seeding, disk harrow + two light disking + seeding, minimum tillage + seeding and four seeding different speeds, as follows: 3, 5, 6 and 9 km h-1. The study was performed under field conditions in FCA / UNESP, Botucatu County, SP, Brazil. The data were subjected to variance analysis in a simple factorial 4 x 4, and a random block design with split plots. Operational performance of the agricultural machinery, physical characteristics the soil, its water content and the yield of dry matter and green sorghum were determined. The operational performance of agricultural machines in the deployment of sorghum forage is influenced by the sowing speed and the soil tillage system used. Chisel plow was the equipment that required the highest mean traction force, mean traction and slip, as well as the lowest mean speed for the studied tillage system. Forage sorghum showed higher yields in no-tillage systems at a seeding speed of 5 km h-1.O sorgo forrageiro pode ser cultivado em áreas e situações ambientais secas e quentes, onde a produtividade de outras forrageiras pode ser normalmente antieconômica.

    Full Text Available A utilização de lodo industrial inorgânico em substratos comerciais ou como fonte de nutrientes, é prática bem recente. O lodo produzido pela indústria de galvanoplastia-zincagem apresenta elevados teores de nutrientes como Zn, Fe, e Ca que, dependendo das doses utilizadas em solos e substratos, podem causar toxidez às plantas. No presente experimento foi utilizado um substrato comercial onde foram adicionadas doses crescentes do lodo industrial de galvanoplastia-zincagem para o cultivo de crisântemo, variedade Rage, em cultivo protegido. As doses do lodo industrial utilizadas foram de 0,0; 0,38; 0,75; 1,50; 3,0; 6,0; 9,0 e 12,0 g L-1 de substrato. Após 12 semanas de cultivo foram avaliadas as seguintes variáveis: pH e condutividade elétrica do substrato, teor de Zn na parte aérea da planta e no substrato, altura da planta (ALT, massa seca da parte aérea (MSPA, massa seca das inflorescências (MSF e massa seca do sistema radicular (MSR. A adição do lodo industrial no substrato, na dose de 0,38 g L-1, promoveu um pequeno incremento de ALT, MSPA e MSR. Este comportamento indica que o lodo industrial pode fornecer nutrientes à cultura. Nas doses superiores a 3 g L-1 ocorreu acentuada queda da produção devido ao desbalanço nutricional associado à fitotoxidez de Zn e elevada condutividade elétrica do substrato.The use of inorganic industrial sludge as a source of nutrients in growing media is a recent practice. The sludge produced by the zinc-galvanic industry has a high concentration of plant nutrients such as Zn, Fe and Ca that, depending on the doses used in soils and growing media, could be toxic to the plants. In the present experiment a commercial organic substrate was used by adding increasing doses of an industrial sludge produced by a zinc-galvanic industry.

    The article explores the importance of agricultulture in line with development of society. It uses examples of high productivity achieved in grain and cotton crops in lnner Mongolia and Xinjiang areas to show that the fundamental objective of agricultural science is to maximize crops through the most effective use of soil, fertilizer and water in gaining the greatest benefit from power of the sun. Agricultural science should take up relevant theories and methodologies from other sciences, such as biological science, earth science and economics. The use of information technology will have great benefits for agricultural science. It hopes the scientific communities of China can make a significant contribution to solving the problems facing our rural areas, farmers and agriculture itself.

    Full Text Available Neste estudo, realizado em quatro microrregiões da Paraíba no período de 1990 a 2005, objetivou-se determinar as correlações entre as precipitações pluviais durante a safra para as culturas de cana-de-açúcar e abacaxi, nas microrregiões do Litoral e Brejo, e as correlações entre as precipitações durante o período chuvoso e as produtividades de algodão herbáceo, na microrregião do Sertão e do sisal, no Cariri/Curimataú. Os testes realizados com as equações de regressões polinomiais utilizando-se apenas a precipitação pluvial da pré-estação chuvosa ou do período chuvoso como variável independente, não foram suficientes para estimar a produtividade da cana-de-açúcar no Litoral, vez que pequenos volumes de precipitação não suprem as necessidades hídricas da cultura. A produtividade do abacaxi não mostrou correlações significativas com as precipitações pluviais nas microrregiões do Litoral e Brejo. Obtiveram-se fortes correlações entre as precipitações pluviais durante o período chuvoso e as produtividades de algodão herbáceo no Sertão paraibano e, para o sisal no Cariri/Curimataú. Com a estimativa da precipitação durante o período chuvoso poder-se-á decidir plantar, ou não, em determinada microrregião.This study was carried out in four homogeneous pluviometric micro regions of Paraíba State between 1990 and 2005. The aims were to determine the relationships between crops of sugar-cane and pineapple productivity and production season rainfall in the Litoral and 'Brejo' micro regions, the relationships between the rainy season precipitations and herbecious cotton productivity in the Sertão, and sisal in the Cariri/Curimataú micro regions. Tests accomplished with polinomial regression equations, using only early rainy season or rainy season as the independent variable were not sufficient to estimate sugar-cane productivity in the Litoral, therefore small rainfall quantities do not supply the

    This study is based on the available data on the georeferred database of the Brazilian oil and gas government regulatory agency (ANP - Agencia Nacional do Petroleo Gas e Biocombustiveis) regarding the position, year of drilling and results of the oil and gas wells drilled in Brazil. The position of the wells were plotted on their sedimentary basins and grouped into five periods (1922-1953, 1954-1961, 1962 - 1970, 1971-1997, after 1997). For each period some of the most significant changes in the technical or institutional background were compiled and reported. Those maps allowed an interesting discussion on the criteria and methodology used to establish the prospect locations at each period and presented a possible explanation for the very low productivity of drilling in Brazil up to the 80's as much as the changes in the conceptual basis that lead to the successful performance of the 90's and the first decade of the 21st century (author)

    Full Text Available Problem statement: Considering unsustainable agricultural conditions of Iran and organizational recession and inability of current extension organization to achieve sustainability, it seems that extension systems require a new organizational structure to achieve sustainability objectives. The purpose of the present study was to identify the most appropriate characteristics for extension organization toward green agriculture in Iran context. Approach: To fulfill this objective, a sample of 120 respondents was selected through simple random sampling technique. A survey study was applied as a methodology of research. A mailed questionnaire was used to collect the data. The response rate of questionnaire was 65.83% (N = 79. Appropriate descriptive statistics such as mean scores, standard deviations and variation ratio were used. Results: Extension experts believed that among important organizational characteristics of extension system for supporting green agriculture collaboration among research, extension, education organizations, farmers' associations, NGOs, rural credit agencies, transportation companies, considering local groups and learning organization had very high importance for supporting green agriculture. According to factor analysis, the implications for extension organization were categorized into two groups consisting: (1 Holistic organizations (2 Participatory organizations that those factors explained 67.54% of the total variance of the research variables. Conclusion: Identifying suitable extension mechanisms had important role for developing extension system. Therefore, identifying extension organizational characteristics for supporting green agriculture of Iran is one of the major approaches needs to be carefully thought and accurately implemented for the extension system development.

  20. MODERNIZATION OF AGRICULTURE VS SUSTAINABLE AGRICULTURE

    2014-04-01

    Full Text Available The paper shows the correlation between the need to modernise agriculture and sustainable development. Modernisation of agriculture aiming only at increasing the efficiency of production, if implemented in accordance with the principles of sustainable development, enabled reduction in the negative external effects. Modernisation of agriculture is supposed to ensure productivity growth without imposing any threats to the natural environment and the well-being of animals, reduced impoverishment in rural areas as well as to ensure food security, growth in the profitability of farms, improvement to the efficiency of use of natural resources. Therefore, in the near future, the agriculture – environment relation will be subject to change taking into account, on the one hand, concern about the natural environment, and, on the other, pressure on increasing the efficiency of production. The above challenges will be addressed by the need to implement efficient and, at the same time, environmentally-friendly production technologies and relevant legal instruments which oblige agricultural producers to protect the natural environment.

    Full Text Available After becoming self-standing state one of new needs of Croatia important for agricultural profession, farmers, policy makers and public needs was regionalization of agriculture. It is the analyse of state of agroecological conditions in agrosphere and based on results identification and territorial separation of agricultural regions as parts of agrosphere with similar conditions for plant and animal growing and similar farming systems. On this track within a special project we fi nished an inventory of agrosphere, result of which is Regionalisation of Croatian Agriculture presented in this paper. Following wise message of old Chinese proverb cited above, the starting approach is the MFCAL concept (Multifunctional Character of Agriculture and Land, which means that apart from very important and primary economic, agriculture and agricultural land (soil in human life play other roles (functions of similar importance; environmental, social, cultural and spatial, as well as the role of shaping the cultural landscape as a factor of rural development. As well, we respect the point of view prevailing in EU that all natural resources used in agriculture but at the fi rst place soil as a major one, need sustainable use and efficient protection. Using the data on Land resource potential based primarily on data of General Soil Map of Croatia (GSM in a scale of 1:50 000 and results of our research in the period 2000 – 2003, the agrosphere of Croatia is divided in three agricultural regions; Pannonian with four, Mountain with two and Adriatic with three subregions.

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

    Purpose: Concern about the environmental impact of agriculture caused by intensification is growing as large amounts of nutrients and contaminants are introduced into the environment. The aim of this paper is to identify the geogenic and agricultural controls on the elemental composition of European, grazing and agricultural soils. Materials and methods: Robust factor analysis was applied to data series for Al,B,Ca, Cd,Co, Cu, Fe, K, Mg,Mn, Na,Ni, P, S, Se, Sr, U, Zn (ICP-MS) and SiO2, K2O, Na2O, Fe2O3, Al2O3 (XRF) based on the European GEMAS dataset. In addition, the following general soil properties were included: clay content, pH, chemical index of alteration (CIA), loss on ignition (LOI), cation exchange capacity (CEC), total organic carbon (TOC) and total carbon and total sulfur. Furthermore, this dataset was coupled to a dataset containing information of historic P2O5 fertilization across Europe. Also, a mass balance was carried out for Cd, Cu and Zn to determine if concentrations of these elements found in the soils have their origin in historic P2O5 fertilization. Results and discussion: Seven geogenic factors and one agricultural factor were found of which four prominent ones (all geogenic): chemical weathering, reactive iron-aluminum oxide minerals, clay minerals and carbonate minerals. Results for grazing and agricultural soils were near identical, which further proofs the prominence of geogenic controls on the total elemental composition. When the cumulative amount of P2O5 fertilization was considered, no extra agriculture-related factors became visible. The mass balance confirms these observations. Conclusion: Overall, the geological controls are more important for the total soil chemistry in agricultural and grazing land soils than the anthropogenic controls.

Precision agriculture is an integrated agricultural management system incorporating different science disciplines e.g. crop science, agricultural engineering and geostatistics. It also uses numerous tools i.e., geographic information system (GIS, Global Positioning System (GPS, remote sensing yield monitors. Because of the multidisciplinary character of precision agriculture, books published on this subject differ in their content. The first books on this topic appeared in the mid 90’ of the last century. The intention of this paper is to present reviews of three books the titles of which each contains the term “precision agriculture”.

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

    2014-09-01

    Agricultural biodiversity is a key part of the ecosystem biodiversity, but it receives little concern. The monoculture, environmental pollution and habitat fragmentation caused by agricultural activities have threatened agricultural biodiversity over the past 50 years. To optimize agricultural management measures for crop production and environmental protection, we reviewed the effects of agricultural activities, including cultivation patterns, plastic mulching, chemical additions and the cultivation of transgenic crops, on agricultural biodiversity. The results showed that chemical pesticides and fertilizers had the most serious influence and the effects of transgenic crops varied with other factors like the specific transgene inserted in crops. The environmental risk of transgenic crops should be assessed widely through case-by-case methods, particularly its potential impacts on agricultural biodiversity. It is important to consider the protection of agricultural biodiversity before taking certain agricultural practices, which could improve agricultural production and simultaneously reduce the environmental impacts.

  6. Greenhouse gas mitigation options in Brazil for land-use change, livestock and agriculture Opções de mitigação de gases do efeito estufa na mudança do uso da terra, pecuária e agricultura no Brasil

    Full Text Available National inventories of anthropogenic greenhouse gas (GHG emissions (implementation of the National Communications are organized according to five main sectors, namely: Energy, Industrial Processes, Agriculture, Land-Use Change and Forestry (LUCF and Waste. The objective of this study was to review and calculate the potential of greenhouse gas mitigation strategies in Brazil for the Agricultural and LUCF. The first step consisted in an analysis of Brazilian official and unofficial documents related to climate change and mitigation policies. Secondly, business as usual (BAU and mitigation scenarios were elaborated for the 2010-2020 timeframe, and calculations of the corresponding associated GHG emissions and removals were performed. Additionally, two complementary approaches were used to point out and quantify the main mitigation options: a following the IPCC 1996 guidelines and b based on EX-ACT. Brazilian authorities announced that the country will target a reduction in its GHG between 36.1 and 38.9% from projected 2020 levels. This is a positive stand that should also be adopted by other developing countries. To reach this government goal, agriculture and livestock sectors must contribute with an emission reduction of 133 to 166 Mt CO2-eq. This seems to be reachable when confronted to our mitigation option values, which are in between the range of 178.3 to 445 Mt CO2-eq. Government investments on agriculture are necessary to minimize the efforts from the sectors to reach their targets.Inventários nacionais acerca de emissões de gases do efeito estufa (GEE (refinamentos das Comunicações Nacionais são organizadas de acordo com cinco principais setores, a saber: Energia, Processos Industriais, Agropecuária, Mudanças do Uso da Terra e Florestas e Tratamento de Resíduos.

  7. The cultivated agricultural environment

    International Nuclear Information System (INIS)

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

  10. Measuring Agricultural Bias

    DEFF Research Database (Denmark)

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

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

    Interdependence has always been central to economics but assumes pressing importance for agricultural economists as they deal with industrialising agricultures. Continued unresolvable uncertainties, when properly recognised, also add to the challenge of relevant work in agricultural economics. The related roles of interdependence and uncertainty are illustrated through examples from the progress of agricultural technology and enhancement of food security.

  11. Researches on Agricultural Cooperative Economic Organization Promoting Agricultural Insurance Development

    Institute of Scientific and Technical Information of China (English)

    2011-01-01

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

The urgency to address sustainability issues is increasingly being reflected in the manner in which institutions of higher education around the world are giving priority to the teaching, research and practice of sustainability. The University of Tuscia is involved in international initiatives concerning teaching and research in Agroecology and Sustainable Agriculture.

  17. Poll Tax in Agriculture

    Full Text Available Under the crisis constrains, the Romanian government tries to balance the budget, to stop the inflation and decrease unemployment, but its financial possibilities to do so prove to be much smaller than necessary. As far as agriculture is concerned, because of the strong connection of this branch to the European rural mechanism, the state intervention plays the key role in the protection and promoting the national production, in competition with other global producers. The taxation system still owes unexpected effects, influences the prices for the animal and vegetal production, the sales and the profits of this branch, in the context of included fluctuating profit particularities. Is poll tax a possibility or a necessity for agriculture?

Man survival in the biosphere will depend on its ability of using four technologies - mechanization, fertilizers, irrigation and pest disease control. The isotopes are usefull to establish means of producing more food and to preserve it; and clains of unbearable damages to the ecosystems caused by fertilizers and pesticides are not true, are presented.

    An opinion piece published in Nature proposed a global network for agricultural monitoring [J. Sachs, R. Remans, S. Smukler, L. Winowiecki, S. J. Andelman, K. G. Cassman, D. Castle, R. DeFries, G. Denning, J. Fanzo, L. E. Jackson, R. Leemans, J. Leemans, J. C. Milder, S. Naeem, G. Nziguheba, C. A. Palm, J. P. Reganold, D. D. Richter, S. J. Scherr, J. Sircely, C. Sullivan, T. P. Tomich and P. A. Sanchez, Nature, 2010, 466, 558-560.]. Whilst we agree with Sachs et al. that monitoring of agricultural systems is a critically important activity of global significance, especially given increasing problems with global food security and the potential impacts of agriculture on the environment [J. Cribb, The Coming Famine. The Global Food Crisis and What We Can Do to Avoid It, CSIRO Publishing and University of California Press, Melbourne and Oakland, 2010.], we argue in this paper that their generic, mandated monitoring framework has a high probability of failure or at best will be highly inefficient. We base this conclusion on our recently published examination of the factors influencing the success or failure of monitoring programs worldwide [D. B. Lindenmayer and G. E. Likens, Effective Ecological Monitoring, CSIRO Publishing and Earthscan, Melbourne and London, 2010.]. We briefly outline what we believe are three serious flaws in the monitoring framework proposed by Sachs et al. We then suggest an alternative approach that we argue would be more effective, more efficient, and have a greater chance of successfully addressing key issues in sustainable agriculture.

The other organizations involved in nuclear agricultural research are Institute of Food and Radiation Biology and Bangladesh Agricultural University. A number of technologies have been developed using nuclear techniques that imparted on agricultural development. Sixteen new crops were developed using physical (200-700 Gy gamma rays) and chemical mutagen (NaN3). Soil fertility and plant nutrition technologies were developed using both stable and radio isotopes. The improved feeding strategies and utilization of locally available low quality feed material (rice straw) were determined using 51Cr-EDTA and 125I in order to have better livestock growth and reproduction ability. Several constraints related to nuclear research were identified. Increased government commitment and international cooperation are of the utmost importance for effective utilization of the benefits of nuclear technology and to face the increasing demand for food for the ever increasing population in years to come

Objective: To analyze the audiological profile of this population, verifying the work's influence on its hearing. Method: It was realized a retrospective, individual, observational, and cross-sectional study through the data obtained by means of a questionnaire and audiometric thresholds of 41 agricultural pilots. To the statistical analysis were utilized the chi-square, Spearman, and Wilcoxon tests with significance level of 5%. Results: It was verified that 95,1% of the pilots use PPE ( personal protective equipment during flight and 58,5% have contact with pesticides. More than half of individuals referred to feel auditory and extra auditory symptoms, being the buzz the more frequent (29,1%. It has the occurrence of 29,3% of NIHL suggestive hearing loss and 68,3% of normality, taking this presence of unilateral notch in 24,4% and bilateral notch in 31,7%. It was found correlation statistically significant in the associations between time of service and the average of the acute frequencies in the right ear (p=0038, and in the left ear (p=0,010. It has a statistical tendency in the association between audiometric configuration and contact with pesticides (p=0,088. Conclusion: The hearing loss prevalence in this study was showed high. More than half of the sample has normal audiometric thresholds with notch configuration. Such data lead to the conclusion that the agricultural pilots, even with PPE use, they still suffer with the damages caused by noise, needing best proposals of hearing loss prevention.

  7. Food, soil, and agriculture

    International Nuclear Information System (INIS)

    The growing pressures on the world's land resources will result in problems requiring a major research effort.The first group of problems relates to increased soil degradation. The research to alleviate this will have to incorporate not only physical and biological solutions, but also pay much more attention to the socio-economic context in which the conservation programmes need to succeed.The second major area for research on land resource is to make better use of low-capacity or problem soils.This could be by reducing the existing limitations, such as changing physical or chemical characteristics of the soil, or by developing plants and production techniques which reduce the detrimental effects of constraints. Example of these are acidity, salinity, and aluminium toxicity. Finally the broadest and more important area is that of research to enable more intensive use of better-quality land. Research topics here may relate to optimal plant nutrient management, soil moisture management, and developing cultivation techniques with minimum commercial energy requirements. Making plants more productive will involve research aimed at increasing photosynthetic efficiency, nitrogen fixation, disease and pest resistance, improved weed control, and bio-engineering to adjust plant types to maximize production potentials. Improved rotational systems for the achievement of many of the above goals will become increasingly important, as the potential problems or inappropriate cultivation practices become evident. In conclusion, food supplies of the world could meet the rapidly rising demands that are made on them, if agriculture receives sufficient attention and resources. Even with most modern development, land remains the base for agriculture, and optimal use of the world's land resources is thus crucial for future agricultural production

    Full Text Available Biostimulants, which may be derived from a wide range of natural or synthetic processes, are now widely used in agriculture and yet the mode of action of these materials is not well understood. On the basis of available literature, and based upon the diversity of biostimulant responses highlighted in this focus issue, we hypothesize that biostimulants function by directly interacting with plant signaling cascades or act through stimulation of endophytic and non-endophytic bacteria, yeast and fungi to produce molecules of benefit to the plant. The benefit of the biostimulant is derived from the reduction in assimilates that are diverted to non-productive stress response metabolism.

    Full Text Available Farms of CSA types are a viable alternative to trade of agricultural products coming from conventional agriculture. These farms are faced with a number of policy issues related to product, price, distribution and promotion. In order to elucidate the issues listed above, we have investigated the literature of specialty. Farmers must make more flexible the content of basket both quantitatively and in terms of the nature of food products offered. Consumers need information on ways of preparation or preservation of products. The growth of the processing degree in farm, and inclusion in the offer of services in ecotourism represent effective options to satisfy consumers. To offset the negative impact of high prices measures should be taken in reducing costs, more flexibility in rescheduling of payments due from customers and compensate for the lack of financial resources with the provision of farm work or subsidize a portion of the basket value from private or government sources. Delivery of baskets should be both at fixed points and at customers domicile. Farmers must provide customers the possibility so that they could harvest themselves the products they will buy. Negative influence of prices will be reduced by establishing an effective communication policy with the market, by organizing events on the farm or nearby towns, through blogs and social networks, and through participation in fairs and exhibitions. A greater customer involvement in farming activities will lead to the implementation of an effective marketing mix.

  14. AGRICULTURE DISEASE MITIGATION SYSTEM

    Full Text Available Around 52% of the population of India rely on farming for their livelihood which accounts for 17% of India’s GDP. Whilst most farmers are familiar with conventional farming practices, they are often ill positioned to promptly deal with diseases and plant infestations affecting their crops. Current advisory systems tend to be generic and are not tailored to specific plots or farms. This work comprises an agriculture advisory call center similar to a modern call center to provide an agriculture disease mitigation system. The information regarding an individual farm is collected using mobile phones. The image of diseased/infected crop is also captured using mobile phones and is made available to the expert to provide the advisory. To scale the advisory, an attempt is also made to automate the disease recognition process using image processing. Unfortunately, the photos taken will be sensitive to a number of factors including camera type and lighting incident on the scene. Ideally, the images would be processed in such a way as to provide the expert with a visual representation of the affected crops that reflects the true nature of the scene. We describe a framework for standardising the colour of plant images taken using both mobile phones and compact cameras within the context of the advisory system.

    As global populations continue to increase, agricultural productivity will be challenged to keep pace without overtaxing important environmental resources. A dynamic and integrated approach will be required to solve global food insecurity and position agriculture on a trajectory toward sustainability. Genetically modified (GM) crops enhanced through modern biotechnology represent an important set of tools that can promote sustainable agriculture and improve food security. Several emerging biotechnology approaches were discussed in a recent symposium organized at the 13th IUPAC International Congress of Pesticide Chemistry meeting in San Francisco, CA, USA. This paper summarizes the innovative research and several of the new and emerging technologies within the field of agricultural biotechnology that were presented during the symposium. This discussion highlights how agricultural biotechnology fits within the context of sustainable agriculture and improved food security and can be used in support of further development and adoption of beneficial GM crops.

  18. Urban agriculture in Botswana

    Directory of Open Access Journals (Sweden)

    Aloysius Clemence Mosha

    2016-02-01

    Full Text Available Botswana, a middle-income country, is experiencing a sluggish economic growth and a rapid urbanisation which has brought in its wake high unemployment, poverty and food insecurity. This has led some people to engage in subsistence and commercial urban and peri-urban agriculture (UPA to address these problems. However, in spite of its known advantages, uptake of UPA has been low for a number of reasons including: high GDP before the economic meltdown of recent years; a harsh climate; lack of water; poor access to land; and over-reliance on generous government handouts. Nevertheless, the extent of its practice and its contribution to food security – albeit modest – shows that it is a sector that needs to be encouraged and supported. Both central and local government can play a big role by providing land and infrastructure, and also by implementing an enabling policy and regulatory environment which promotes small- and medium-scale urban food production.

  1. Water Depletion Threatens Agriculture

    Brauman, K. A.; Richter, B. D.; Postel, S.; Floerke, M.; Malsy, M.

    2014-12-01

    Irrigated agriculture is the human activity that has by far the largest impact on water, constituting 85% of global water consumption and 67% of global water withdrawals. Much of this water use occurs in places where water depletion, the ratio of water consumption to water availability, exceeds 75% for at least one month of the year. Although only 17% of global watershed area experiences depletion at this level or more, nearly 30% of total cropland and 60% of irrigated cropland are found in these depleted watersheds. Staple crops are particularly at risk, with 75% of global irrigated wheat production and 65% of irrigated maize production found in watersheds that are at least seasonally depleted. Of importance to textile production, 75% of cotton production occurs in the same watersheds. For crop production in depleted watersheds, we find that one half to two-thirds of production occurs in watersheds that have not just seasonal but annual water shortages, suggesting that re-distributing water supply over the course of the year cannot be an effective solution to shortage. We explore the degree to which irrigated production in depleted watersheds reflects limitations in supply, a byproduct of the need for irrigation in perennially or seasonally dry landscapes, and identify heavy irrigation consumption that leads to watershed depletion in more humid climates. For watersheds that are not depleted, we evaluate the potential impact of an increase in irrigated production. Finally, we evaluate the benefits of irrigated agriculture in depleted and non-depleted watersheds, quantifying the fraction of irrigated production going to food production, animal feed, and biofuels.

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

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

  12. Potential fly-ash utilization in agriculture: A global review

    2009-01-01

    Though in last four decades various alternate energy sources have come into the limelight, the hyperbolic use of coal as a prime energy source cannot be counterbalanced. Disposal of high amount of fly-ash from thermal power plants absorbs huge amount of water, energy and land area by ash ponds. In order to meet the growing energy demand, various environmental, economic and social problems associated with the disposal of fly-ash would continue to increase. Therefore, fly-ash management would remain a great concern of the century. Fly-ash has great potentiality in agriculture due to its efficacy in modification of soil health and crop performance. The high concentration of elements (K, Na, Zn, Ca, Mg and Fe) in fly-ash increases the yield of many agricultural crops. But compared to other sectors, the use of fly-ash in agriculture is limited. An exhaustive review of numerous studies of last four decades took place in this paper, which systematically covers the importance, scope and apprehension regarding utilization of fly-ash in agriculture. The authors concluded that though studies have established some solutions to handle the problems of radioactivity and heavy metal content in flyash, long-term confirmatory research and demonstration are necessary. This paper also identified some areas, like proper handling of dry ash in plants as well as in fields, ash pond management (i.e., faster decantation, recycling of water, vertical expansion rather than horizontal), monitoring of soil health, crop quality, and fate of fly-ash in time domain, where research thrust is required. Agricultural lime application contributes to global warming as Intergovernmental Panel on Climate Change (IPCC) assumes that all the carbon in agricultural lime is finally released as CO2to the atmosphere. It is expected that use of fly-ash instead of lime in agriculture can reduce net CO2emission, thus reduce global warming also.

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

  12. Climate Change and Agricultural Vulnerability

    International Nuclear Information System (INIS)

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

Foram utilizados os espaçamentos 1 m x 1 m, 2 m x 1 m e 2 m x 2 m para plantio de Acacia angustissima, Clitoria racemosa, Inga edulis e Acacia mangium. A espécie Sclerolobium paniculatum foi plantada somente no espaçamento 2 m x 1 m. Na condução do experimento, o milho permaneceu no experimento nos primeiros quatro meses e considerado como monocultura, produziu 1.890 +/- 32 kg ha-1. A sobrevivência das árvores, plantadas junto com milho e na mesma época da mandioca, não sofreu interferência negativa das culturas agrícolas. Independente do espaçamento, as árvores não causaram impacto negativo no peso seco das raízes de mandioca. Quanto a densidade de árvores observou-se tendência de aumento do peso seco das raízes de mandioca com a diminuição do número de árvores plantadas por hectare. Os resultados evidenciam a possibilidade de se manter a produtividade agrícola associada ao plantio de árvores. Entretanto, a opção pelo espaçamento 1 m x 1 m deve ser cuidadosamente analisada quando o objetivo principal for a produção de alimentos.

    2013-03-01

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

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.

    Kumar, Manish; Tomar, Rajesh Singh; Lade, Harshad; Paul, Diby

    2016-07-01

    Excessive use of chemical fertilizers to increase production from available land has resulted in deterioration of soil quality. To prevent further soil deterioration, the use of methylotrophic bacteria that have the ability to colonize different habitats, including soil, sediment, water, and both epiphytes and endophytes as host plants, has been suggested for sustainable agriculture. Methylotrophic bacteria are known to play a significant role in the biogeochemical cycle in soil ecosystems, ultimately fortifying plants and sustaining agriculture. Methylotrophs also improve air quality by using volatile organic compounds such as dichloromethane, formaldehyde, methanol, and formic acid. Additionally, methylotrophs are involved in phosphorous, nitrogen, and carbon cycling and can help reduce global warming. In this review, different aspects of the interaction between methylotrophs and host plants are discussed, including the role of methylotrophs in phosphorus acquisition, nitrogen fixation, phytohormone production, iron chelation, and plant growth promotion, and co-inoculation of these bacteria as biofertilizers for viable agriculture practices.

    Full Text Available The inhabitants of Khairpur Taluka mostly consume groundwater for drinking and agriculture purposes. The present study was conducted to monitor the essential quality parameters of groundwater and soil. Both groundwater and soil samples of the area were classified as alkaline. All the major ions except Na and SO4 were found within the permissible limits, while the concentrations of Zn, Fe, Co, Pb, Ni and Mn in studied groundwater samples were found above the specified limit of WHO. However, soil samples were found rich in major and trace elements except Cd, which was low in comparison to world average of agriculture soil. Irrigation character of water samples on SAR vs. Na% plot display fair type with few exceptions. The piper diagram implied mixed water composition with Na-Ca-Mg and HCO3-SO4+Cl as dominate ions. Diverse shapes of Stiff polygons also support the mixed nature of groundwater in the study area.

  15. Agriculture: access to technology limited.

    Science.gov (United States)

    1997-01-01

    From country to country and even regionally, the roles of women in agriculture vary, but most of their labor is in unpaid subsistence production and their contributions tend to be underestimated, according to the results of the [UN] Secretary-General's report. Depending on circumstances, they have complementary roles with men, sharing or dividing tasks in the production of crops, care of animals, and forestry management. In sub-Saharan Africa, for example, women contribute 60-80% of labor in food production for both household consumption and sale, while in Malaysia the women account for only 35% of the agricultural labor force, and in Ireland the participation rate is only 10.4%. Although women make this important amount of labor contributions to agricultural production, "development policies tend to favor export crops to earn foreign exchange and the agricultural research tends to address the improvement of production and technologies for commercial production". This results in limited access for women to technical knowledge and innovations, including irrigation, machinery, farming techniques and extension services. This is strengthened by the fact that most of the extension services target farmers who own land and can obtain credit to invest in input and technology. PMID:12293737

  18. Saline agriculture in Mediterranean environments

    Directory of Open Access Journals (Sweden)

    Albino Maggio

    2011-03-01

    Full Text Available Salinization is increasingly affecting world's agricultural land causing serious yield loss and soil degradation. Understanding how we could improve crop productivity in salinized environments is therefore critical to meet the challenging goal of feeding 9.3 billion people by 2050. Our comprehension of fundamental physiological mechanisms in plant salt stress adaptation has greatly advanced over the last decades. However, many of these mechanisms have been linked to salt tolerance in simplified experimental systems whereas they have been rarely functionally proven in real agricultural contexts. In-depth analyses of specific crop-salinity interactions could reveal important aspects of plant salt stress adaptation as well as novel physiological/agronomic targets to improve salinity tolerance. These include the developmental role of root vs. shoot systems respect to water-ion homeostasis, morphological vs. metabolic contributions to stress adaptation, developmental processes vs. seasonal soil salinity evolution, residual effects of saline irrigation in non-irrigated crops, critical parameters of salt tolerance in soil-less systems and controlled environments, response to multiple stresses. Finally, beneficial effects of salinization on qualitative parameters such as stress-induced accumulation of high nutritional value secondary metabolites should be considered, also. In this short review we attempted to highlight the multifaceted nature of salinity in Mediterranean agricultural systems by summarizing most experimental activity carried out at the Department of Agricultural Engineering and Agronomy of University of Naples Federico II in the last few years.

    In some agricultural regions, natural wetlands are scarce, and constructed agricultural ponds may represent important alternative breeding habitats for amphibians. Properly managed, these agricultural ponds may effectively increase the total amount of breeding habitat and help to sustain populations. We studied small, constructed agricultural ponds in southeastern Minnesota to assess their value as amphibian breeding sites. Our study examined habitat factors associated with amphibian reproduction at two spatial scales: the pond and the landscape surrounding the pond. We found that small agricultural ponds in southeastern Minnesota provided breeding habitat for at least 10 species of amphibians. Species richness and multispecies reproductive success were more closely associated with characteristics of the pond (water quality, vegetation, and predators) compared with characteristics of the surrounding landscape, but individual species were associated with both pond and landscape variables. Ponds surrounded by row crops had similar species richness and reproductive success compared with natural wetlands and ponds surrounded by nongrazed pasture. Ponds used for watering livestock had elevated concentrations of phosphorus, higher turbidity, and a trend toward reduced amphibian reproductive success. Species richness was highest in small ponds, ponds with lower total nitrogen concentrations, tiger salamanders (Ambystoma tigrinum) present, and lacking fish. Multispecies reproductive success was best in ponds with lower total nitrogen concentrations, less emergent vegetation, and lacking fish. Habitat factors associated with higher reproductive success varied among individual species. We conclude that small, constructed farm ponds, properly managed, may help sustain amphibian populations in landscapes where natural wetland habitat is rare. We recommend management actions such as limiting livestock access to the pond to improve water quality, reducing nitrogen input, and

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

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

    2010-09-01

    The North Dakota Agricultural Weather Network (NDAWN) consists of 72 automated weather stations spread across agricultural locations of North Dakota, the Red River Valley, and border regions of surrounding states. The NDAWN Center is a part of the Department of Soil Science, North Dakota State University. The NDAWN stations measure wind speed and direction, air temperature, rainfall, solar radiation, pressure (31 stations), atmospheric moisture and soil temperatures under bare and turf at 10 cm (4 inch) depth. The center provides daily summaries consisting of maximums and minimums as well as time of occurrence, and various totals or averages for all variables in English or metric units. Measured and calculated variables along with complete descriptions are available. The NDAWN Center web site: http://ndawn.ndsu.nodak.edu/ allows direct access to NDAWN data in various special and temporal scales. The voice modem accommodates those who do not have internet access. The NDAWN Center has assisted many North Dakotans in making weather critical decisions concerning their crops, livestock, and livelihood. The stations provide weather data, which was instrumental in developing various agricultural models including but not limited to the late blight model, degree day and growth stage models for barley, corn, canola, potato, sugarbeet, sunflower, wheat and other small grains, irrigation scheduling, crop water use, sugarbeet root maggot, and insect development models. Late blight model, for example, predicts when leaf disease can occur in potato plants. Late blight doesn't occur in North Dakota every year and is prevalent during cool and moist periods of weather. In 1993-94, this model predicted that late blight would occur and growers were able to use fungicide applications to prevent the disease. Another direct benefit of NDAWN data is that it provides universities and the National Weather Service with an additional database for research and forecasting applications

    Full Text Available Problem statement: Jordans agricultural extension service is seriously under-staffed and its effectiveness is consequently compromised. Reservations are being expressed about the performance and capability of the agricultural extension system in Jordan. The performance of this sector has been disappointing and has failed to transfer agricultural technology to the farmers. The main objective of this study is to assess the effectiveness of Jordans agricultural extension services. Approach: The effect of extension services on olive productivity in the study area was investigated. A total number of 60 olive producers were selected to be interviewed for this study. This number was enough to achieve the study objectives. The interviewed producers were distributed almost equally within olive production locations in the study area. The sample obtained through the simple random sampling technique. The two groups had been chosen and distributed randomly into an experimental group (30 farmers; 10 for each source of extension service and control group (30 farmers. The experimental group received extension services and the control group received no extension services. Two interview-cum-structured questionnaires were designed and used to collect information and data for this study. The first instrument was designed for farmers who received extension services and the second from farmers who received no extension services. Another questionnaire was designed for administrators of extension organizations concerned with providing extension services to farmers. To find the differences that may exist between two studied groups, One Way Analysis of Variance (ANOVA, t-test and LSD test via Statistical Package for Social Sciences software (SPSS were used. The average net profit obtained from an area of one dynamo of olive farm was the main item to be considered in determining the effectiveness of agricultural extension activities.

  17. Groundwater recharge and agricultural contamination

    Böhlke, J.K.

    2002-01-01

    Agriculture has had direct and indirect effects on the rates and compositions of groundwater recharge and aquifer biogeochemistry. Direct effects include dissolution and transport of excess quantities of fertilizers and associated materials and hydrologic alterations related to irrigation and drainage. Some indirect effects include changes in water-rock reactions in soils and aquifers caused by increased concentrations of dissolved oxidants, protons, and major ions. Agrilcultural activities have directly or indirectly affected the concentrations of a large number of inorganic chemicals in groundwater, for example NO3-, N2, Cl, SO42-, H+, P, C, K, Mg, Ca, Sr, Ba, Ra, and As, as well a wide variety of pesticides and other organic compounds. For reactive contaminants like NO3-, a combination of chemical, isotopic, and environmental-tracer analytical approaches might be required to resolve changing inputs from subsequent alterations as causes of concentration gradients in groundwater. Groundwater records derived from multi-component hydrostratigraphic data can be used to quantify recharge rates and residence times of water and dissolved contaminants, document past variations in recharging contaminant loads, and identify natural contaminant-remediation processes. These data indicate that many of the world's surficial aquifers contain transient records of changing agricultural contamination from the last half of the 20th century. The transient agricultural groundwater signal has important implications for long-term trends and spatial heterogeneity in discharge.

Human & animal muscle power and machinery energy for tillage operation, electricity and diesel energy for irrigation, fertilizer and pesticides energy for growth and protection are taken into account. Energy values are calculated by multiplying respective quantity by their respective energy equivalents with the use of relevant conversion factors. Energy flow studied based on some energy dependent indicators: energy input per ha, energy output per ha, energy output to input ratio, mechanization index, energy input to generate per unit GDP output as well as per unit output in energy term and solar energy conversion efficiency. During the study period, energy input and output to Bangladesh agriculture were increased from 6.4 to 17.32 GJ ha-1 and 72.22 to 130.05 GJ ha-1, respectively. It is found that energetic efficiency (energy output to input ratio was declined from 11.28% to 8.1%, which indicates that the energy input increased faster than energy output. It is expected that sustainable energy flow in Bangladesh agriculture can be ascertained by this study.

    The number of urban agriculture practitioners has been increasing rapidly in Korea like many other urbanized countries recently. The Korean government enacted a law for promoting urban agriculture in 2011. However, urban soil environment can be potential sources of many toxic contaminants including heavy metals making people concern about the safety of the agricultural products from the urban agriculture. The accumulation of heavy metals in soil and plant by overuse of compost from animal waste was one of the raised concerns. This study was carried out to find out properties and total and phytoavailable (1.0 M NH4NO3 extractable) contents of heavy metals (Cd, Pb, Cu, Zn) in 21 urban agricultural soils in Seoul. On the average, the investigated urban soils showed pH1:5 6.89, EC1:5 0.14 dS m-1, organic mater 2.22%, available P2O5 139 mg kg-1, cation exchange capacity (CEC) 11.36 cmolc kg-1 and total nitrogen 0.15%. The average exchangeable-Ca, -Mg, -K and -Na of the 21 samples were 6.71, 1.44, 1.06 and 0.30 cmol+ kg-1, respectively. Total heavy metal concentrations (Cd 0.97-3.17 mg kg-1, average 1.89 mg kg-1; Pb 8.10-46.27 mg kg-1, average 19.96 mg kg-1; Cu 8.97-133.40 mg kg-1, average 38.37 mg kg-1; and Zn 38.97-180.06 mg kg-1, average 97.73 mg kg-1) in urban agricultural soils were lower than those of the warning standard in the area 1 according to the Soil Environmental Conservation Act of Korea. Phytoavailable-Cu, -Pb, and -Zn concentrations of the samples showed 0.02-0.28, N.D-0.09 and 0.01-0.43 mg kg-1, respectively. Phytoavailable-Cd was not detected. The average phytoavailable-Cu concentration from this study was similar to that from the previous phytoavailable-Cu of the highly contaminated soils from nearby abandoned mines, which might be resulted from overuse of compost from animal waste. Results showed a necessity of long-term monitoring of soils for sustainable urban agriculture in Korea.

    The plantation of forests has been recommended as one of the forms to prevent the effect greenhouse caused for the increase of the concentrations of determined gases in the terrestrial atmosphere. Climatic prevision have taken some organizations to consider behavior rules, with the purpose to minimize the emission of the greenhouse gases. The reduction of the greenhouse gases is one of the goals of the Kyoto Protocol. To make possible the implementation of its intentions, the Kyoto Protocol established commercial mechanisms, calls of 'flexibility mechanisms', amongst them, the Clean Development Mechanism - CDM. One of the lines of project considered eligible in the CDM is the called projects of carbon sequestration. This type of project, besides reducing CO{sub 2} of the atmosphere, contributes for the sustainable development, providing diverse useful goods and services to the man. Brazil will be able to assume a privileged position together to the countries that they search to revert the process of global climatic change, seating forest projects, edaphoclimatic conditions, availability of land, man power and the domain of technology are factors that contribute significantly for the attraction of investments of this nature.

  19. Bacteriocins from the rhizosphere microbiome - from an agriculture perspective.

    Science.gov (United States)

    Subramanian, Sowmyalakshmi; Smith, Donald L

    2015-01-01

    Bacteria produce and excrete a versatile and dynamic suit of compounds to defend against microbial competitors and mediate local population dynamics. These include a wide range of broad-spectrum non-ribosomally synthesized antibiotics, lytic enzymes, metabolic by-products, proteinaceous exotoxins, and ribosomally produced antimicrobial peptides (bacteriocins). Most bacteria produce at least one bacteriocin. Bacteriocins are of interest in the food industry as natural preservatives and in the probiotics industry, leading to extensive studies on lactic acid bacteria (colicin produced by Escherichia coli is a model bacteriocin). Recent studies have projected use of bacteriocins in veterinary medicine and in agriculture, as biostimulants of plant growth and development and as biocontrol agents. For example, bacteriocins such as Cerein 8A, Bac-GM17, putidacin, Bac 14B, amylocyclicin have been studied for their mechanisms of anti-microbial activity. Bac IH7 promotes tomato and musk melon plant growth. Thuricin 17 (Th17) is the only bacteriocin studied extensively for plant growth promotion, including at the molecular level. Th17 functions as a bacterial signal compound, promoting plant growth in legumes and non-legumes. In Arabidopsis thaliana and Glycine max Th17 increased phytohormones IAA and SA at 24 h post treatment. At the proteome level Th17 treatment of 3-week-old A. thaliana rosettes led to >2-fold changes in activation of the carbon and energy metabolism pathway proteins, 24 h post treatment. At 250 mM NaCl stress, the control plants under osmotic-shock shut down most of carbon-metabolism and activated energy-metabolism and antioxidant pathways. Th17 treated plants, at 250 mM NaCl, retained meaningful levels of the light harvesting complex, photosystems I and II proteins and energy and antioxidant pathways were activated, so that rosettes could better withstand the salt stress. In Glycine max, Th17 helped seeds germinate in the presence of NaCl stress, and was

    Constructing the modern agriculture with Chinese characteristics is the path and direction for solving issues concerning agriculture, countryside and farmers in China, the key to new village construction, the important measure for promoting overall agricultural production capacity, and the prerequisite and guarantee for coordinating urban-rural development. At present, the level of agricultural mechanization in China is promoted steadily; the science and technology are applied to agriculture extensively; the agricultural regionalization layout gradually takes shape; the agricultural industrialization management develops steadily. Be that as it may, the overall quality of farmers is low; the agricultural infrastructure is weak; the agricultural resources are limited; the inputs of agricultural science and technology are short. These hamper the development of modern agriculture. We should implement "industry nurturing agriculture"; through capital support and policy guidance, reform household registration system; connect the fragmented land into parcel; encourage the leading enterprises to develop in rural areas; establish agricultural cooperative organizations; deepen rural financial system reform; quicken the promotion and application of agricultural technology. These measures can effectively promote the development of agriculture, and realize the agricultural modernization in China.

    Hot and cold mineral waters are used in two ways in agriculture: one for irrigation and other as a heat resource. Irrigation is widely applied in Turkey when the chemical composition of water is found suitable for the purpose. However as a heat resource it is almost never used. Studies showed that the hot waters of Turkey have 4665 billion kcal (equivalent of 450 thousand tons) which means green-houses can be established over an area about 4665 decar for growing vegetable and fruits. The approximate income of the green houses is estimated millions of Turkish lira.

    The onset and course of puberty is under the control of the neuroendocrine system. Factors affecting the regulation of timing and order of this system's functions may alter the onset and course of puberty. Several environmental endocrine disruptors (EDs) with significant influences on the normal course of puberty have been identified. Despite the numerous animal and human studies on EDs that may extensively affect human health, there are still several issues that need to be clarified.

    Full Text Available Problem statement: Knowledge Management (KM as a “starter” and Agricultural Knowledge Information System (AKIS act as an “engine” to sustainable development. Approach: This article explored the role of KM as Agricultural Knowledge Initiative (AKI to link up agricultural research and extension to foster agricultural development. A dominant-less dominant design was applied to describe the KM and AKIS integration frameworks as an interpretive process. Clarification of KM stance in AKIS was made through hermeneutic approach in the qualitative part of the study. In quantitative part of the study, 'Expedite Finding Transmission of Agricultural Research (EFTAR Project was explained as the empirical evidence. Results: Although KM and AKIS were not new concepts in agricultural science, but AKI and the New Agriculture (NA, in the way that we intermingled them in this article to encourage the end-users’ partnership and agricultural development, are quite new issues. Conclusion: To provide the domain of any use of proposed models elsewhere and facilitate the international application of KM in AKIS and AKI, practical suggestions were presented. Applying this state of art in agricultural development in over 1000 production units, caused obtaining 57% increase in rain fed wheat production in probationary areas in Iran.

    Full Text Available Neste texto pretende-se discorrer sobre valores morais na escola e suas implicações para a formação de professores. Para tanto discutir-se-á, em primeiro lugar, e brevemente, o que são valores morais, ou éticos, e como a escola pode situar-se em relação a eles. Em seguida, serão relatadas algumas observações a respeito de valores de professores e práticas daí decorrentes. São comentados resultados de pesquisa que ilustram a transmissão de valores de forma doutrinal e a educação moral e cívica tal como realizada na ditadura militar, e, por outro lado, a posição relativista e/ou de laissez-faire que certas escolas podem adotar, metodologicamente, sobre a educação em valores. Finalmente, defender-se-á a idéia de que é necessária uma discussão sobre valores pelos diversos membros da escola e uma opção por uma metodologia para ensiná-los, seja os professores, em sua formação inicial e continuada, seja os alunos. A teoria de desenvolvimento moral de Jean Piaget será apresentada como uma referência possível para a educação em valores. Exemplos de situações escolares de conflito de valores entre direção, pais e alunos são discutidas para ilustrar como uma escola pode adotar um procedimento democrático de educação em valores, que se apresenta como um terceiro caminho possível de educação moral nas escolas, além das posições doutrinárias ou relativistas.

  10. Karst and agriculture in Australia.

    1999-01-01

    Full Text Available Much of the development and degradation of karst lands in Australia has occurred in the last two centuries since European settlement. Recent prolonged El Nino events add further climatic uncertainty and place real constraints on sustainable agriculture. The lower southeast of South Australia is perhaps the one area in Australia where karst, and particularly karst hydrology, impinge on the daily lives of the community in that pollution and overexploitation of the aquifer are readily apparent to the local population. Effluent from intensive dairy farms, piggeries and cheese factories enters the karst and has caused concern over pollution of water supplies. Human impacts on the Mole Creek karst of Tasmania have been well documented. The principal recent impacts on the karst arc associated with land clearance for farmland, forest cutting for timber, road building, refuse disposal and associated hydrological change. There is similar evidence of agricultural impacts un karst in central New South Wales, with clear evidence of vegetation clearance and soil stripping on the limestones at Wellington, Orange and Molong.

    1985-01-01

    During the past 6 years, 375 patients were hospitalized with injuries resulting from farm accidents. The mechanism of injury was farm animal in 135 patients (36%), tractor in 89 (24%), corn picker or auger in 57 (15%), power take-off in 29 (8%), other farm machinery in 50 (13%), and miscellaneous in 15 (4%). Injury severity score (ISS) of 25 or greater was calculated for 29 individuals (8%). Eleven groups of surgical subspecialists performed 539 procedures. Eight patients (2.1%) died as a result of their injuries. All eight deaths occurred after tractor accidents secondary to pelvic fractures, head and spinal cord injury, or blunt chest trauma. Thirty-nine patients (10%) were left with serious permanent disability. Unnecessary morbidity and mortality in many cases were attributed to excessive prehospital care times within a largely rural area. Better prevention by farmer education and the initiation of mandatory safety devices on agricultural equipment may lower the incidence of farm accidents. Major agricultural trauma is frequent and diverse and is optimally managed in a regional trauma center. PMID:4093573

  12. Renewable energy sources in agriculture

    International Nuclear Information System (INIS)

    Greenhouse crop evolution if from one hand improves the quality of products and productive cycles, from another hand cause negative effects on the natural resources, the environment and the economy of the country. Although renewable energies already feature to some extent in the European Union's regional, the 2007-2013 Structural Funds package could be the occasion to increase the weight given to RES within the energy programmes for less favoured regions (particularly in ex-objective 1 areas). In those areas, greenhouse crop sector is particularly developed as agriculture industrial activity. According to numerous investigations, agricultural greenhouse consumption for greenhouse acclimatization represents approximately between 2% to 6% of the E U's-27 total energy consumption. This report is intended to give a general overview to the potential of renewable energy and technology in Italy, particularly geothermal, wind and solar (thermic and photovoltaic) as energy for greenhouse crop sector. RES have a high potential for developing of indigenous resources, service activities, new job creation and reducing Co2 emissions.

    Full Text Available In Front of new prospects and the environmental concerns with sustainable development, always more the science, communities, institutions of education and general managers have been engaged in developing new strategies and methodologies to work in urban and rural area. The aims are not harming the environment and optimize the processes of action, trying to maximize profits. The objective of this study was to verify the current state of knowledge of environmental education and dissemination of information on subsistence agriculture, within the national context. The methodology was based on a qualitative literature review, with exploratory character, exposing the main arguments used and their applicability. The results showed that although there are many options to work for environmental education in family agriculture, few things has been done in practice. It was verified that the main focus of environmental education in the field is restricted to activities with planting of seedlings for reforestation of degraded areas and conservation of riparian forests. Although, the environmental education may involve several techniques aimed at improving the quality of life in the field. Also, working only with "green marketing" themes are not that interesting, when we talk about sustainability.

    Full Text Available Para Hume, filosofar é uma atividade semelhante às demais ocupações humanas. A decisão que leva à atividade filosófica é menos resultado de uma argumentação teórica do que fruto de um cálculo prático, que é entendido como uma caça ou um jogo. O objetivo deste trabalho será o de mostrar que no jogo filosófico perde quem joga sério demais. A aposta na filosofia tem que passar pelo bom humor e pela diversão: uma resposta a Pascal?For Hume, philosophy is in itself neither more nor less important than other human activities. On the contrary, it can be explained from its resemblance with game and hunting. If one chooses to dedicate himself to philosophy, his decision is not the consequence of logical reasoning, but depends on practical evaluation, which has something to do with gambling. The following text tries to show that in philosophy, like in other games, the loser will be the one who plays too earnestly. The philosophical game requires good humour and some relaxation: Is this a good answer to Pascal's pari?

    Full Text Available Problem statement: Without doubt, it is important to expose and educate farmers with the current and updated agriculture information. To implement this, the related agriculture agencies in Malaysia should consider the best channels for them in spreading the needed valuable agriculture information to the farmers. The question that can be raised now, can the mass media be the right channel for agriculture information dissemination and is the mass media has been utilized in disseminating the agriculture information to the farmers. Approach: This is a conceptual study discussing the usage of mass media in disseminating agriculture information. The data of this study are gained through literature analysis and document analysis. The data is presented descriptively. Results: Based on the analyses done, it was found that majority of Malaysian nowadays can afford to own their own mass media such as television, radio and internet. The number of available television channels, radio channels and newspapers either free or paid are encouraging. Currently, there are three television agriculture programs aired on RTM, while currently there are five agriculture radio programs aired on local radio stations, one program aired on Klasik National FM and the other four programs aired on four different states FM. For newspapers, there are two daily newspapers that provide agriculture information to their readers namely Utusan Malaysia and Berita Harian. Based on the data gained, usage of internet especially on website surfing must be encouraged among the farmers. Mobile web system initiated by five agriculture agencies in Malaysia is seen as a wise step for information dissemination and information sharing. Conclusion: Even though mass media in Malaysia has played its role in disseminating agriculture information, the number of programs and spaces produced and provided can be doubled, hence it is recommended that local giant agriculture based companies can play their

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

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

Assorted parameters like temperature, pH, EC, TDS, Cl-, SO42-, HCO3-, sodium, potassium, calcium, magnesium, SAR values as well as the Piper and Stiff diagrams were determined to confer a clear picture of quality parameters in ground water and agriculture soil of the area. The present investigations conclude that the maximum parameters are not at the level of pollution except major metal ions Na+ and Ca2+. The higher concentration of Ca2+ and Na+ could be due to the deposits of the salts of these elements into soil, which may had leached into ground water. The Piper diagram suggest that composition of water is (Na++K+-(Ca2++Mg2+-HCO3--(Cl-+SO42--type. The areal distribution of stiff diagram constructed for groundwater samples showed ionic balances, indicating the major ion analyses are of good quality. Therefore, both ground water and soil samples observed are satisfactory for their utilization in various purposes such as domestic, agricultural, industrial, etc.

The changes in production efficiencyinvestigated using stochastic frontier methods, show declining technicalefficiency in livestock production and especially low marginal contribution oflabor inputs. The number of workers, size of farm, and distance from nearestcity are related to efficiency in agricultural production. It is well known thatresults from an environmental policy in response to global climate change arequite sensitive to the assumption on the rate of energy efficiency improvements.However, technical progress is traditionally considered as a non-economicvariable in economic policy models. It is exogenous in most policy evaluationsas well as in the theory of environmental economics.

    2014-01-01

    This paper studied the effects of crop insurance on agricultural output with an economic growth model. Based on Ramsey-Cass-Koopmans (RCK) model, a basic model of agriculture economic growth was developed. Extending the basic model to incorporate uncertainty and insurance mechanism, a risk model and a risk-insurance model were built to study the inlfuences of risk and crop insurance on agricultural output. Compared with the steady states of the three models, the following results are achieved:(i) agricultural output decreases if we introduce uncertainty into the risk-free model;(ii) crop insurance promotes agriculture economic growth if insurance mechanism is introduced into the risk model;(iii) premium subsidy constantly improves agricultural output. Our contribution is that we studied the effects of crop insurance and premium subsidy from the perspective of economic growth in a dynamic framework, and proved the output promotion of crop insurance theoretically.

    Agricultural productivity is expected to be sensitive to global climate change. Models from atmospheric science, plant science, and agricultural economics are linked to explore this sensitivity. Although the results depend on the severity of climate change and the compensating effects of carbon dioxide on crop yields, the simulation suggests that irrigated acreage will expand and regional patterns of U.S. agriculture will shift. The impact of the U.S. economy strongly depends on which climate model is used.

  15. Influence of NaCl and NaHCO/sub 3/ on reduction of phytic acid in red kidney bean

    International Nuclear Information System (INIS)

    Influence of sodium chloride (NaCI) and sodium bicarbonate (NaHCO/sub 3/) was studied on phytic acid in Red kidney bean (phaseolus sp). Two varieties of Red Kidney bean VI (Orakzai Korkha) and V2 (Kurram Korkha) were obtained from NWFP Agriculture University, Peshawar. The amount of phytic acid in V1 and V2 of Red kidney bean was 10 mg and 9.80 mg, respectively. Red kidney-bean flour soaked for 6 and 12 hrs. in water and in pH4 and 6 solutions has significantly reduced (70%) amount of phytic acid. Solution of pH6 was found most effective, while pH4 and water was less effective in lowering the phytic acid in Red kidney bean. Mixed food additives (1% NaCI + 2% NaHCO/sub 3/) in water, and pH4 and 6 solutions, reduced the level of phytic acid in Red kidney bean to 40%, 54% and 58% for 6 hrs, and 50%, 57% and 70% for 12 hrs. in respective solutions. Results revealed that soaking Red kidney bean flour in pH6 solution with the presence of NaCI and NaHCO/sub 3/, the action of phytase enzyme was well activated to hydrolyze phytic acid. It has been observed that soaking of flour in the respective solutions is a simple inexpensive method of lowering phytic acid in bean. The treatment with such a sophisticated combination of food additives will improve the nutritional status of Red kidney bean, which is used in many food products. (author)

    2012-12-01

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

    Full Text Available Water reform policy in many countries, which their economy mostly based on agricultural sector, is main preconditions for sustainable agricultural economic development. Since water is an important input in all economic sectors and particularly in agriculture, climate changes and water scarcity are more important to be considered in this millennium. Providing sufficient water for various uses is one of the main problems that most Developing Countries involved. Agricultural Water-reforms are vital while the multi-oriented issue of sustainability is of interest as well. The pros and cons of climate changes due to global warming and water-reform policy are discussed in this project.

    Full Text Available O momento nazista permanece um enigma impensado de que a cultura contemporânea continua cativa. O autor levanta a hipótese de que a persistência desse enigma e seus estragos duráveis se devem à insistência dos pensamentos político, sociológico e filosófico em construírem o nazismo à luz da metáfora hobbesiana do Leviatã. Propõe retomar a questão do nazismo sob a perspectiva do Behemoth, antônimo do Leviatã. Para tanto, sugere a necessidade de retornar a Freud e à psicanálise, balizas de um possível novo pensamento do político que escrutine a destrutividade nazista. Propõe ainda sondar as homologias entre nazismo, corjas e máfias, com base na figura da " heroicização da violência" que lhes seria comum. E avança um modelo " econômico" : a quimera, suscetível de capturar o caráter heterotópico e heterocrônico de sua construção criminosa.The paths of Behemoth. The Nazi moment remains as the thoughtless enigma of which contemporary culture is still captive. The author raises the hypothesis where the persistency of this enigma and its durable damages are due to the insistence of the political, social and philosophical thoughts in building the Nazism at the view of the Hobbesian metaphor of Leviathan. It is here proposed to resume the Nazism matter under Behemoth's perspective, antonym to Leviathan. For such, it is suggested a necessity to look back at Freud and the psychoanalysis, structured by a possible new political thought which scrutinizes the destructivity of the Nazism. It is also here proposed to gaze at the homologies between Nazism, mafias and gangs, with a base in the figure of " violence as a heroically act" that are their common ground. The author also advances an economical model: the chimera susceptible to capture the heterotopic and heterochronic character of its criminal construction.

    2011-09-01

    Full Text Available Study of agriculture enjoys less popularity over time in most of the developed countries, including Canada and the Czech Republic. Analysis in this paper provides interesting findings about activities of agricultural universities to increase enrollment into their programs. While the study is focused on Canada, it is possible to draw implications also for the Czech Republic as many of the characteristics pertaining to the education and agricultural sectors are similar. Enrollment into educational programs in agriculture in North America has been steadily declining in the last several decades. While the overall share of agriculture on national gross domestic product has also been falling, the need for qualified people in agriculture is still eminent as the shift to sustainable agriculture appears to be one of the key priorities of governments in the US and Canada. One of the ways how to facilitate interest of prospective students to study agriculture is to diversify the programs through offering of more major options. It is important to study the motivation and other stimuli for the choice of major in order to adapt the educational programs and attract more students. In the paper, factors influencing the choice of major are studied by analyzing survey data from the only agricultural college in Atlantic Canada. The results show significant differences in the socio-economic background among the prospective students based on the choice of major. For example, students interested in social sciences much more appraise more choices of major than students in biophysical fields. Based on the findings from the analysis, several recommendations are made. It is suggested, for example, that for students interested in biophysical sciences, sport plays an important role and thus, appropriate promotional campaign about recreation and sport facilities of a post-secondary agricultural educational institutions should be conducted. Analysis in this paper may serve

    Full Text Available The increasing demand for water has made the treatment and reuse of wastewater a topic of global importance. This work aims to monitor and evaluate the efficiency of a wastewater treatment plant’s (WWTP physical and biological treatment of wastewater by measuring the reduction of organic matter content of the effluent during the treatment and the disposal of nutrients in the treated residue. The WWTP has been designed to treat 2500 liters of wastewater per day in four compartments: a septic tank, a microalgae tank, an upflow anaerobic filter and wetlands with cultivation of Zantedeschia aethiopica L. A plant efficiency of 90% of organic matter removal was obtained, resulting in a suitable effluent for fertigation, including Na and Ca elements that showed high levels due to the accumulation of organic matter in the upflow anaerobic filter and wetlands. The WWTP removes nitrogen and phosphorus by the action of microalgae and macrophytes used in the process. The final effluent includes important agricultural elements such as nitrogen, phosphorus, calcium and potassium and, together with the load of organic matter and salts, meets the determination of NBR 13,969/1997 (Standard of the Brazilian Technical Standards Association for reuse in agriculture, but periodic monitoring of soil salinity is necessary.

    2011-06-01

    Full Text Available Ensuring food security is an ongoing global challenge. Many forecasts point to a need to increase food production by at least 70% if we are to feed the world’s projected population of nine billion in 2050. Recent volatility in commodity prices and the general upward trend in the cost of food are indicators that global food systems are now driven by demand rather than supply. There are various reasons for this: greater demand for animal protein with economic growth in developing countries; the continuing increase in world population; competition between food and bioenergy crops for land and water; low inventories of world grain stocks; reduced investment in agricultural R&D; and unfavorable weather resulting in a succession of poor harvests around the world. Increasing production of grains, which are the foundation of the human food supply, will have to be achieved through higher crop yields without boosting inputs of land, water and energy. Meeting community expectations for environmental stewardship and sustainability, and adapting food production to increasingly variable climate, add greatly to the challenge.

    Full Text Available Propolis has been ground in various areas of science, but its application in agriculture, is a recent and almost unknown subject. In agronomy work mainly seek to explore the antibiotic and antifungal properties of propolis, but other uses have been proposed, such as plant nutrition, pest control (such as mites and even reducing water stress in plants. Despite numerous utilities proven and proposals, there are many questions, particularly for the preparation of the extract, most appropriate chemical composition for a particular use, application forms, crude propolis extract in percentages, dose minimum efficiency, efficiency, etc. Given the above, the purpose of this literature review is to present the origin and chemical composition of propolis, making methodology of propolis extract, more effective dose in the control of fungi, plant pathogenic bacteria and reduce water stress. During the study, it can be seen that the difference in propolis composition occurs mainly due to the variability of vegetable composition in the vicinity of the hive, the bees forage and chemical composition is quite complex and variable in terms of both concentration and chemicals gifts. In the extraction, there are still many gaps to be studied, including the best way to obtain the extract, with questions about the best puller, with lack of consensus in the literature. On the efficiency of this technology, there are numerous studies with promising results, which allow implementation of technology in the field and these jobs concentrated in coffee crops, beans, cucumber and tomato.

    Full Text Available The main goal of the paper is to map the performance of Romanian farms from the perspective of livestock agricultural operations using principal component analysis technique (PCA and similarities between Romania and other countries from UE. The empirical results reveal that animal breedings farms are grouped into two categories :small and middle sized farms ; and the fact that Romania , one of Europe’s major forces in the field of livestock husbandry, has come to be one of the biggest importers of food products, although, by tradition, it is one of the continent’s countries with ideal conditions for breeding all species of animals. When clustering the countries we observ that in countries such as Greece, Italy, Portugal, Spain, cow farms, for example, do not exceed 10-16 heads and in Holland, England, Denmark, Belgium and France, the average farm size reaches 30-70 heads of milk cows. The cluster analysis revealed that in livestock operations, animal stock is the one that generates production, while the animal number indicates the size of the livestock unit.

  11. Agriculture and growth nexus in Gambia

    Directory of Open Access Journals (Sweden)

    Bukhari Sillah

    2013-12-01

    Full Text Available Agriculture is a major engine for the economic well-being of the Gambia. The successive governments from the colonial periods to the present have all recognized this importance of the agricultural sector but failed to do something that bear any fruit since government encouraged slash and burn technology and putting increasingly more people onto the land instead of increasing the yields per acre. More people than before do remain still on the land, but they are now poorer than their forefathers. Using autoregressive and vector error correction techniques to examine the growth-agriculture relation in the Gambia for the period from 1966 to 2009, it is found that the capital per worker is a significant and relevant factor input for the economic growth. The agricultural labor per acre is found to be irrelevant in both the short run and the long run analyses. The agricultural productivity measured as crop yields per acre is the most important variable for the economic growth in the Gambia. It boosts both the economic growth and the capital formation in the country. The agricultural policies should be focused on increasing the crop yields per acre not having more people back to the land. The processing, services and small manufacturing sectors should be developed and built into the agricultural policies in order to create redeployments for the agricultural labor surpluses.

  12. Agricultural intensification escalates future conservation costs.

    Science.gov (United States)

    Phelps, Jacob; Carrasco, Luis Roman; Webb, Edward L; Koh, Lian Pin; Pascual, Unai

    2013-05-01

    The supposition that agricultural intensification results in land sparing for conservation has become central to policy formulations across the tropics. However, underlying assumptions remain uncertain and have been little explored in the context of conservation incentive schemes such as policies for Reducing Emissions from Deforestation and forest Degradation, conservation, sustainable management, and enhancement of carbon stocks (REDD+). Incipient REDD+ forest carbon policies in a number of countries propose agricultural intensification measures to replace extensive "slash-and-burn" farming systems. These may result in conservation in some contexts, but will also increase future agricultural land rents as productivity increases, creating new incentives for agricultural expansion and deforestation. While robust governance can help to ensure land sparing, we propose that conservation incentives will also have to increase over time, tracking future agricultural land rents, which might lead to runaway conservation costs. We present a conceptual framework that depicts these relationships, supported by an illustrative model of the intensification of key crops in the Democratic Republic of Congo, a leading REDD+ country. A von Thünen land rent model is combined with geographic information systems mapping to demonstrate how agricultural intensification could influence future conservation costs. Once postintensification agricultural land rents are considered, the cost of reducing forest sector emissions could significantly exceed current and projected carbon credit prices. Our analysis highlights the importance of considering escalating conservation costs from agricultural intensification when designing conservation initiatives. PMID:23589860

  17. Na Deposition on MnO(100)

    Science.gov (United States)

    Feng, Xu; Cox, David F.

    2016-03-01

    Na deposition on the MnO(100) surface was investigated by temperature programmed desorption (TPD), X-ray photoelectron spectroscopy (XPS) and low energy electron diffraction (LEED). Na TPD and XPS results indicate that adsorbed Na interacts strongly with the MnO substrate to form an irreversibly-adsorbed, oxidic Na compound on the surface for coverages up to 1 monolayer (ML). This strongly-bound Na diffuses into the MnO subsurface and bulk at elevated temperatures above 500 K. For Na coverages above 1 ML, metallic Na is present and desorbs from the surface below 500 K. The deposition of Na on MnO(100) follows a Stranski-Krastanov (SK) growth mode, with the formation of metallic Na islands following completion of the first Na monolayer. After Na deposition, the surface exhibits a diffuse (1 × 1) LEED pattern, suggesting the formation of disordered Na overlayers. After heating to 1000 K, the surface presents a (2 × 2) LEED pattern indicating that a surface reconstruction is induced by the diffusion of Na into the near surface region. CO2 can be used as a probe molecule in TPD to distinguish between metallic Na islands and oxidic Na in the first ML, and to indicate when Na that is still observable by XPS goes subsurface.
