Resumen

The subject of this study is the rural settlements in Classical Greece. There is no doubt that there were various factors determined the ancient settlement patterns in Greek countryside. Geographical conditions, socio-economic and political structures can be regarded as major significant factors behind the settlement practices of ancient societies. In this study the relationships between agricultural system and rural settlements of Classical Greece will be examined.

Resumen

The purpose of this study was to understand the teaching practices of the Agriculture Faculty at Bangladesh Agricultural University (BAU). This study is at the intersection of the critical assessment and examination of assumption and exploring options and plans stages of transformative learning theory (Mezirow, 2000) and the environment factor of Astin's I-E-O model. Previous studies showed that tertiary education of Bangladesh fails to develop critical thinking abilities among the students. Higher order teaching practices help to develop critical thinking abilities among the students. Thus, it is important to explore the level of teaching practices at the Agriculture Faculty of BAU to understand how it supports critical thinking abilities among the students. Graduates being able to use critical thinking skills to solve agricultural issues will increase total food production and reduce national poverty. This study was an instrumental single case study. Faculty of Agriculture of BAU was the unit of analysis for this study. The findings of this study were only generalizable to the Agriculture Faculty at BAU and only relevant for Summer 2020. The phenomenon of this study was teaching practices at the Agriculture Faculty of BAU. Data sources included a census survey of active faculty members and content analysis of course syllabi. Findings from this study suggested that both teaching methods and course learning outcomes of the courses of the Agriculture Faculty at BAU were related the lower order of Revised Bloom's Taxonomy (RevBT). Moreover, faculty members from biological science and engineering used more teaching practices from evaluating level of RevBT than social science disciplines. Evaluating level is considered as higher level of RevBT. Male faculty members also used more teaching practices related to analyzing level than female faculty members. Analyzing level is also considered as higher level of RevBT. Faculty members identified that they have lack of training, standard teaching resources to use higher order teaching practices. Moreover, they also said that students of the Agriculture Faculty at BAU are more interested in job preparation than classroom education. However, faculty members also felt that higher order teaching practices can improve the creativity and critical thinking abilities for students and brings enthusiasms in teaching. Faculty members recommended that BAU revise its curriculum, syllabi, and assessment strategies to create higher order teaching practices in classrooms. As a result of this study, there is opportunity for faculty to increase their use of higher order teaching practices and develop course outcomes that support higher order learning. In addition, the university should revise their existing curricula and assessment techniques and give more freedom to the faculty members to choose their teaching and assessment methods. Finally, training should be organized to support higher order teaching by female faculty members.

The purpose of this case study was to understand the teaching practices of the Agriculture Faculty at Bangladesh Agricultural University (BAU). Conceptually, this study was coupled up with transformative learning theory (Mezirow, 2000) and the Astin's I-E-O model. The unit of analysis of this study was the educational environment provided by Agriculture faculty of BAU that offers a single under-graduate degree program called B.Sc. Ag. (Hons.). A structured survey questionnaire was used to collect data from the faculty members of the Agriculture Faculty of BAU based on Revised Bloom's Taxonomy (RevBT). Additionally, all course syllabi were analyzed to identify the level of intended teaching practices based on RevBT. RevBT is the benchmark standard to evaluate the cognitive orders of the teaching-learning process, curriculum planning, instruction, and test tasks. Findings from this study suggested that faculty members slightly more preferred teaching practices from the lower levels of RevBT for the classroom teaching at BAU. Findings also suggested that teaching practices connected to the higher cognitive levels of RevBT were significantly varied based on academic disciplines and gender of the faculty members. Faculty members mentioned that lack of students' interest in classroom lessons, the rigid curricula and existing examination system of BAU, large numbers of students in classes, and lack of training of the faculty members are the main limiting factors for them to use higher order teaching practices in classrooms. However, faculty members also wanted to use the higher order teaching practices in classrooms as higher order teaching practices enhances students' creativity, problem solving skills, and critical thinking skills. Faculty members suggested to update course curricula, syllabi, and the exam system to support higher-order teaching practices at BAU. Findings from the course syllabi analysis supported that most of the action verbs of course learning outcomes of the course syllabi were connected to the lower cognitive levels of RevBT. As a result of this study, there is opportunity for faculty to increase their use of higher order teaching practices and develop courses that support higher order learning. In addition, the university should revise their existing curricula and assessment techniques and give more freedom to the faculty members to choose their teaching and assessment methods. Finally, training should be organized to support higher order teaching by female faculty members.

Resumen

This study examines the current retirement strategies of agricultural producers, determines farmers’ levels of investment and financial planning knowledge, and makes recommendations for the construction of a computer-based expert system to assist producers in developing retirement plans and strategies. The first two objectives are accomplished through the analysis of 336 self-administered and mailed surveys from producers in Iowa, Kansas, Nebraska, Virginia, and Washington. The third objective is completed utilizing study results, information provided by individuals knowledgeable m personal finance, and literature dealing with personal financial management. Seventy percent of the survey respondents invest in non-farm assets. Farmers who do not invest off the farm cite a desire to pay down debt, little or no funds available, tax savings, and liquidity as their leading reasons not to invest off the farm, while those who do invest off-farm list tax benefits and diversification as their leading motivators. Respondents began retirement saving early and one-third of them wanted to begin withdrawing from the farming operation by the age of 60. Seventy-eight percent of the respondents with non-farm jobs invest in assets off the farm (p < .05). Producers with the highest levels of formal education are more likely to invest off the farm than the less educated producers (p < .005). Farmers with less formal education tend to delay investing for retirement until later in life (p < .001).

Resumen

Sudan is the largest country in Africa and boasts the largest farm in the world. Sudan is a predominately agricultural economy; agriculture employs more than eighty percent of the country's labour force and its industry. The national agricultural research institutions are charged with the key responsibility of implementing sustainable agricultural growth and development in Sudan. By adoption of demonstrable benefit farms, the research institutions view their contribution as providing improvements to traditional Sudanese practices rather than focusing on developing new techniques. Any research institution must have methodsof improving farming practices and the pertinent test of their relevance is improved management practices. Crop productivity is extremely low and does not exceed thirty percent of the level attained in research or demonstration fields; the difficult economic position of the country has adversely affected the activities of the agricultural research institutions; technology generation is greatly hampered; the extension service is fragmented and its efforts are conned to a small number of farmers; the research institutions are weakened due to frequent staff turnover, lack of continuity in the research agenda and inadequacies in management and hence their impact is limited. The main purpose of this study is to critically evaluate the implementation capacity constraints which exist in formal agricultural research and the impact this has on thedevelopment of the agricultural sector of the Sudanese economy. The study also attempts to provide a better understanding of the relationships between low productivity in Sudan and the determinants of this. The data for this research were obtained from a field survey carried out in 1999. In the survey, a total of 120 farmers from the Gezira Scheme, 84 researchers from the Agricultural Research Corporation, 33 academic staff from the Gezira University as well as extensionists from the Central State were successfully interviewed. The research explores various aspects of the internal technology transfer system and the productivity gap in traditional agriculture. A critical review of the theoretical and empirical literature on technology transfer has been conducted in the study. It is obvious that economic analysis alone will not provide a satisfactory solution to the type of problems investigated in the study as these issues and problems also have political and socio-cultural dimensions. Therefore, the proposed solutions simply seek to change the behaviours of both individuals and institutions. To do this it is necessary to recognise all the dimensions of the technology transfer problem. This study provides insights into the influence of demographic, socio-economic, cultural, technical and decision-making factors on technology transfer and productivity in Sudan. The thesis concludes with discussion of key policy implications and areas for further research. The findings of this research should assist in guiding planners and policy-makers in improving the internal technology transfer system and perhaps in enabling agricultural productivity to improve in the Sudan.

Resumen

The South Nation watershed consists of an area of roughly 3900 km2 in Eastern Ontario which drains into the South Nation River. The South Nation River in turn drains into the Ottawa River at the watershed outlet. The work presented here included the use of the continuous-simulation Annualized Agricultural Non Point Source (AnnAGNPS) 5.0 dynamic pollutant loading model, which was developed by the U.S. Department of Agriculture (USDA). In-stream water chemistry was also an important element of a meaningful analysis. The dynamic water-quality model CE-QUAL-RIV1 was selected due to its riverine nature, which is closely linked with the AnnAGNPS concept of a channel network. Utilities were developed to enhance the input and output capabilities of both codes. The linked models were then calibrated to the available data, and a case matrix focused on predicting feasibility of best management practices (BMPs) within the context of climate change was constructed and simulated. The calibration process was done manually at first, based on the results of a sensitivity analysis conducted on the AnnAGNPS package as part of the work. Subsequently, the use of an automatic genetic-algorithm based approach (also developed as part of this work) was explored, which yielded an improvement in the calibrated model and was therefore used as a base case of the model. The case matrix examined 4 individual BMPs, along with 4 combined BMP scenarios. (Abstract shortened by UMI.)

Resumen

The role of agriculture in the economy and society remains relevant as the industry provides 11% of employment and affordable access to healthy food which promote health and wellbeing. However, without adequate agricultural literacy, individuals may not be able to make safe and healthy food choices. To explore the level of agricultural literacy of college students, a 43-item questionnaire was developed and will be administered at a Liberal Arts University in the Southeastern United States. The aim of the study is to determine agricultural literacy scores and the importance of agricultural practices among college students who are not and will not be enrolled in agricultural courses and who do not plan to pursue a career in agriculture. Data collected will be examined to determine whether agricultural literacy is related to the importance of agricultural practices and whether relationships between demographic characteristics and agricultural literacy scores are present

Resumen

Many farms in the United States impose negative externalities on society. Population growth and the accompanying increase in demand for food further promote this trend of environmental degradation as a by-product of food production. The USDA's Environmental Quality Incentives Program (EQIP) provides financial assistance to farmers who wish to address natural resource concerns by making structural improvements or implementing best management practices (BMPs) on their farms. Regional examinations of program implementation and incentive levels are needed to evaluate the effectiveness of EQIP at both the farm and environmental level. This research addresses this need in the following two ways. First, conjoint analysis was used to calculate the willingness to accept incentive levels desired by Vermont farmers for implementing three common BMPs and the relative importance of each attribute in their adoption decisions. Next, a survey was conducted to document Vermont farmers' experiences, or choices not to engage, with EQIP. The results of the conjoint analysis indicated that farmers' adoption decisions are most heavily influenced by the available implementation incentives and that the higher the incentive level offered, the more willing farmers are to adopt a practice. The survey results triangulated these findings as cost was the most frequently cited challenge farmers face when implementing BMPs and one third of respondents felt the cost-share amount they had received was inadequate. Although 46% of respondents reported receiving nonmonetary benefits, 43% had encountered challenges when enrolling or participating in EQIP. In addition, though contracts are designed to address specific resource concerns, 30% of respondents had not fully fixed the original issues with their contracts. This also indicates that the incentive levels offered in EQIP contracts may be lower than Vermont farmers' preferred incentive levels, affecting the adoption rate of BMPs and subsequently the environmental health and long term sustainability of Vermont's agricultural systems. Program areas ripe for improvement, key points for farmers weighing the costs and benefits of program participation, and future research opportunities are discussed in order to guide efforts to improve the effectiveness of EQIP in Vermont. This research also raises awareness of how much it costs to simultaneously support environmental health and food production in our current food system and who ultimately should bear this financial burden.

Texto completo

Resumen

The goal of the Mississippi State University Extension Service (MSU-ES) is to improve the quality of life for all Mississippians. One specific group that agricultural change agents work with at the county level is beef producers. Grazing lands have received much attention over the last few years regarding environmental concerns and Best Management Practices (BMPs) for beef cattle operations.

The adoption of these practices was voluntary during the time this study was conducted, however; adoption was highly encouraged by the MSU-ES and the Natural Resources Conservation Service (NRCS). By knowing the level of adoption of BMPs that Mississippi beef producers have implemented, change agents can more effectively plan educational programming efforts for producers to better understand the importance of BMP adoption.

The purpose of this study was to describe the adopter categories of Mississippi beef producers as determined by Rogers (2003) adopter characteristics generalizations based on their (1) socioeconomic status, (2) personality values and communication behavior, and (3) opinions. It also examined the correlations between the adopter categories to predict the level of the three BMPs being studied.

The adopter categories were innovator, early adopter, early majority, late majority, and laggard. The three BMPs that were the focus of the study were rotation grazing, riparian buffers, and pasture renovation.

The results of the study indicated that Mississippi beef producers could be correctly identified in the adopter categories. By identifying the adopter categories of the Mississippi beef producers and then examining the correlations among the variables, prediction of BMP adoption of rotational grazing and riparian buffers was possible.

The relationships between MSU-ES agents and their programming efforts, as well as the relationships between NRCS district conservationist and their programs, were studied. Non-adoption, though not an adopter category, was also examined and the reasons for it were cited.

Resumen

Small plot replicate trials were established to test ten barley varieties, twenty one durum wheat varieties and seven varieties of bread/feed wheat. Yields were exceptionally high in 1998 which were attributed to overall growing conditions for the plants. Gustoe was the highest yielding barley variety with a yield of 8412 pounds per acre, YU894-162 (Western Plant Breeders) was the highest yielding durum wheat with a yield of 7986 pounds per acre and RSI 5 (Resources Seeds Inc.) was the highest yielding feed wheat. These varieties yielded 1458, 966 and 713 pounds per acre more than the number two varieties for barley, durum wheat and wheat, respectively.

Resumen

The aim of this study was to investigate two potential beneficial management practices that will reduce the impact of fecal and fertilizers contamination on the environment. The study was conducted in Eastern Ontario on typical small scale agricultural practices. The first part evaluates the impact of a conventional pasture system and an excluding pasture system on surface water quality. The three year study compared water quality endpoints such as: indicator bacteria, pathogens, parasites and nutrients between treatments. Microbial source tracking indicated that livestock was the main source of fecal contamination in the stream. Greater bacteria and nutrient loads were observed in the unrestricted pasture system than the excluding pasture. Moreover, parasite and indicator bacteria concentrations increased after cattle introduction in both systems. The second part compares nitrogen mass balance between managed and conventional subsurface tile drainage. Over two years, nitrogen loads in groundwater, in tile flow, in plants, in soil and denitrification were compared between treatments. Nitrogen was mostly removed from managed tile drainage fields through plant uptake. Compared to nitrogen plant uptake, denitrification, the second greatest nitrogen removing process was 10 times smaller. The denitrification was greater in the unmanaged tile drainage fields. Generally, managed subsurface tile drainage reduces nitrogen mass loads to surface waters and increases nitrogen uptake by plant, which resulted in greater yields.

Resumen

We study the effect of organic farming practices on several taxa in olive groves and vineyards. Sessile organisms show a stronger response to treatment, their diversity being higher in organic vineyards. Vagile organism show a less intense response, with the most mobile taxa (birds) showing no farming treatment related differences. Organic olive groves are preferred over conventional groves by some endangered bat species (Rhinolophus spp.), thus stressing their importance for bat conservation. We analize the regulatory ecosystems services bats exert in rice paddies. Bats predate on both agricultural pests (moths and midges) and disease-bearing pests (mosquitoes). The intensity with which they track pests is linked to the cost-benefit trade-off, more evidently shifting their hunting grounds when bigger pests are available. Their economic impact has been assessed in terms of the avoided pesticide cost per hectare of rice crop and year at around 50€

Jason S. Bergtold
In recent years, great attention has been placed on conservation systems for agricultural production. Conservation practices offer economic and environmental benefits, yet conventional practices remain the prevailing system in some regions. As conservation efforts are launched by different local and federal agencies, understanding farmers’ motivations when adopting conservation practices is important to ensure the continuation of adoption through the development of programs that are tailored to meet farmers’ preferences and constraints. The purpose of the first essay was to identify the factors affecting farmers’ choice of tillage practice at the crop level. Farmer’s choice of No-till, Strip-till and Conventional tillage was modeled for dryland corn, wheat and soybean production in Kansas. The results show that tillage decisions are crop-specific and that factors such as risk aversion, baling and grazing of crop residue, crop acreage, and farmers’ approach to adopting new technologies are significant factors affecting farmers’ decisions. The second essay focused on the adoption of continuous no-till, conservation crop rotation, cover crops, and variable rate application of inputs and the effect that incentive payments, payment mechanism, and off-farm environmental benefits from conservation have on the decision to adopt. This essay also examined the risk associated with the variability of net returns and its effect on farmers’ willingness to adopt using a non-linear extended expected utility framework, allowing for the estimation of a utility parameter for net returns, farmer’s subjective judgment of probabilities, and farmers’ risk attitudes. Farmers were found to exhibit risk aversion, with an estimated risk premium of approximately 3% of net returns. Results also suggested a preference for federally-run programs and for programs with higher off-farm environmental benefits. The third essay examined the timing of adoption of continuous no-till, cover crops, and variable rate application of inputs. This study found that risk aversion delays the timing of adoption of cover crops and variable rate application of inputs. However, the timing of adoption of continuous no-till was not affected by risk aversion. Findings also indicated that farmers who consider themselves innovators adopt at a faster rate than their counterparts.

Resumen

In 1988, the counties of Appanoose, Davis, Monroe, and Wapello created the Soap Creek Watershed Board. This group put in place a plan to fund and construct 154 farm ponds in an effort to provide water for agriculture practices as well as provide flood protection for the residents inside the Soap Creek watershed. Through collaborative efforts and funding from federal, state, and local sources, to date 132 ponds have been constructed. Currently there is no stream monitoring in place in the watershed to observe stream conditions. This leads to no stored data on the benefits of the projects in the basin and the reduced flood impacts. With funding from the Iowa Watershed Projects (IWP) through the IIHR - Hydroscience & Engineering lab, a lumped parameter surface water model was created to show the benefits of the constructed projects. Using detailed LiDAR data, a Hydrologic Engineering Center-Hydrologic Modeling System (HEC-HMS) model was created. This model used arcHydro and ARC-GeoHMS, tools in ARCgis. Detailed LiDAR, SURGGO soil data, and land cover data was used to create the model parameters. Several design and historical storms were modeled to quantify the benefits in peak flow reductions and in amounts of water stored behind the projects.

Resumen

lt;p align="justify"gt; The modernization of the agriculture is founded on the logic that presupposed an identity between agriculture development and rural development. Where these policies had been implemented, it has been proved that while agriculture modernized, rural poverty persisted and grew, still where it occurred, the familiar agriculturists were excluded from the markets. This allows us to justify that the parameters of rural development surpass the agriculture sphere. This research analyses the strategies of reproduction of familiar farms of the municipality of Santa Maria do Suaçuí, which has passed through a long period of economic stagnation, showing an under-developed agriculture excluded from the technological development. This process generates new techno productive dynamics causing strong impacts on rural development. On one hand, many producers have abandoned the agricultural business freeing family labor force from farming activities. On the other side, there is growing numbers of agriculturists, and their families, who no longer run activities related to agricultural business. In this process it has appeared the pluriactive family, which combines the agricultural activities with the non agricultural businesses, inside and outside the farm. This is a case study of the family farms of Santa Maria do Suaçuí, a municipality that has gone through economic hardship still produces and survives. It was learned that the familiar agriculturists of Santa Maria do Suaçuí established a system of production based in cooperation with each other, characterized by the existing relations of reciprocity e solidarity in community lives. From then on, many agriculturists have become to carry on a variety of different activities, not all directly linked with agricultural. Poultry, milk and vegetables productions are the main strategies of reproduction linked to agriculture. Agroindustrialization and services have also increased. This development of new activities provoke social differentiation, however, the mercantilism didnt imply the proletarianisation of agriculturists, but causes the appearance of new social reproduction strategies. Therefore, it is believed that the main contribution of this study to the familiar agriculture is the analysis of surviving alternatives for familiar agriculturists in economic stagnated areas.lt;/pgt;
lt;p align="justify"gt; A lógica que fundamentou a modernização da agricultura pressupunha uma identidade entre desenvolvimento agrícola e desenvolvimento rural. Sabe-se hoje que, onde essas políticas foram implementadas, a agricultura se modernizou, mas a pobreza rural persistiu e ainda, onde ela ocorreu, os agricultores foram excluídos dos mercados. É justamente este fato que permite afirmar que os parâmetros de desenvolvimento rural transcendem a esfera agrícola. Este trabalho aborda justamente as estratégias de reprodução da agricultura familiar do município de Santa Maria do Suaçuí, que tem passado por um longo processo de estagnação econômica, apresentando uma agricultura atrasada e excluída dos processos tecnológicos. Este processo gera novas dinâmicas técnico-produtivas que causam fortes impactos sobre o meio rural. Por um lado, muitos têm abandonado a atividade agrícola liberando mão-de-obra no interior das famílias. Por outro, aumenta o número de agricultores e de seus familiares ocupados em atividades que não estão mais diretamente relacionadas à agricultura. No âmbito deste processo surgem as famílias pluriativas, as quais passam a combinar as atividades agrícolas com as atividades não-agrícolas, tanto interna como externamente às propriedades. Neste sentido, o presente estudo terá como principio metodológico que o norteia a técnica do estudo de caso que é um recurso pelo qual se procura estudar uma determinada realidade exaustivamente a fim de se obter o máximo de informações possíveis. Trata-se de um estudo empírico que investiga um fenômeno mediante a utilização de várias fontes de evidências, tanto qualitativas quanto quantitativas. A partir dessas técnicas procurou-se verificar como a agricultura familiar em Santa Maria do Suaçuí, um município que tem passado por grande retração econômica, vem se reproduzindo e sobrevivendo. Para tanto se percebe que os agricultores familiares de Santa Maria do Suaçuí estabeleceram um sistema produtivo baseado numa forma de sociabilidade caracterizada pela existência de relações de reciprocidade e solidariedade em nível de comunidade. A partir de então, muitos agricultores passam a se dedicar a diferentes atividades, tanto na agricultura como fora dela. A produção de frangos, suínos, leite e hortaliças, são as principais estratégias de reprodução ligadas à agricultura. A agroindústria e a prestação de serviços são as principais estratégias não-agrícolas. O desenvolvimento das novas atividades leva os agricultores a uma diferenciação social, todavia, a mercantilização não implicou na proletarização dos agricultores, mas no aparecimento de novas estratégias sociais de reprodução. Nesse sentido, acredita-se que a principal contribuição desta dissertação ao estudo da agricultura familiar e da pluriatividade consista na revelação de alternativas de sobrevivência para agricultores familiares de áreas de economia estagnada, bem como do local em que estes processos estão se desenvolvendo.lt;/pgt;

Resumen

The previously developed watershed hydrological and water quality model for St. Louis Bay watershed by Kieffer (2002) was refined and calibrated. The aspects of model development refinement included development of fertilization-related nutrient input parameters, evaluation of nutrient input methods, development of plant uptake-related nutrient input parameters, non-cropland simulation using PQUAL module, and recalibration of hydrology in Jourdan River. The related information of typical cropland management practice based on consultation from Mississippi State University Extention Service personnel was integrated into the watershed model. In addition, the Mississippi Department of Environmental Quality (MDEQ) observed water quality data were analyzed to evaluate the appropriateness of current watershed delineation and assess the health of the stream based on the MDEQ proposed numerical water quality target. The refined watershed model was calibrated in Wolf Rover and Jourdan River using both USGS and MDEQ observed water quality data. The concentrations of water quality constituents calculated from the developed watershed model will be provided as boundary conditions for the developed Bay hydrodynamic and water quality model for Total Maximum Daily Load studies.

Essay one evaluates two farmer field schools aimed at promoting conservation agricultural practices. The field schools were conducted and offered to approximately 1/3 of all individuals surveyed in a baseline in 2010. These same farmers were resurveyed in 2012 in order to determine whether their knowledge of conservation agriculture practices had changed using a double-difference approach. The approach was also used to determine whether innate perceptions and biases against conservation agriculture have changed over time due to training in the field schools. These findings are supported with enterprise budgets of conservation practices to determine whether knowledge or on-farm economics limit adoption of conservation practices. The data showed that farmer-to-farmer communications are effective tools for raising knowledge. Essay two examines the interdependence of sustainable agricultural intensification practices (SAIPs) in order to better understand the constraints and incentives for the adoption of components and “packages” of components. The impact of accumulated knowledge score on the adoption of SAIPs was assessed using data from 168 participant and non-participant farm households that completed a survey in 2014 and 2012 from the Upper West region of Ghana. From a three-step regression, our findings show knowledge of participant household improved with evidence of knowledge spillover to non-participant. Participation, age and gender of the head of household and experience were factors impacting farm household knowledge score change on SAIPs. The study found that, knowledge score through the treatment effect impacts adoption of SAIPs which are complementary. Younger household heads and experience in farming are also found to likely impact adoption. Essay three estimates technical efficiency (TE) scores for millet and sorghum and evaluates the impact of soil and water conservation methods on TE scores. The paper also examines the sensitivity of TE scores on the distributional assumptions of the one-sided error using data from 518 and 754 farm households producing millet and sorghum respectively from a random national household survey in Niger. A Cobb-Douglas stochastic frontier model was used. The mean TE scores range from 52% to 66% and 35% to 60% respectively for adopters and non-adopters of soil and water conservation methods in millet production based on the distributional assumptions of the one-sided error. For sorghum production, the mean TE scores range from 47% to 63% and 39% to 63% respectively for adopters and non-adopters of soil and water conservation methods based on the distributional assumptions of the one-sided error. This suggests inefficiencies in the production of millet and sorghum and hence, the potential to improve output using existing technology. Adopters are relatively more efficient than non-adopters of soil and water conservation methods. The TE score differences in millet production are explained by location of household (rural), educational level and adoption of soil and water conservation. The efficiency score differences in sorghum can be explained by household size, educational level and soil and water conservation adoption. We also found TE scores are sensitive to the distributional assumptions of the one-sided error using the farm household level data.

Resumen

To help local, rural planners make decisions on which Best Management Practices (BMPs) are most appropriate for the control of Non-Point Sources of Pollution (NPSP) within their jurisdiction, a method is developed for unbiased site-specific evaluation of BMPs appropriateness. An appropriate BMP is functional, practical and cost effective. The method developed is a rational method suitable for the general evaluation of agricultural BMPs to control NPSP in rural watersheds. The method is functional, practical, and cost effective because it uses existing data and personnel wherever and whenever possible. Unlike other NPSP modeling methods, this method lends itself to the selective application of BMPs throughout the watershed based on its actual land use and physical composition. This means, BMP's can be applied to the entire watershed uniformly or applied to a subset of the watershed based on selection criteria such as field slope, soil type, or existing cover crop. In addition, a combination of selection criteria can be used, and a combination of BMPs. This flexibility in selecting various BMPs and BMP combinations, allows planners to pose many different schemes for controlling NPSP within the watershed. The results of the schemes can be compared to determine which scheme is the most appropriate for use within the specific watershed. The method developed relies heavily on the United States Department of Agriculture's Soil Conservation Service's (SCS) Universal Soil Loss Equation (USLE) and uses data already being collected by the SCS and the Agricultural Stabilization and Conservation Service (ASCS). The method does require the creation of Hydrologic Response Units (HRUs) comprised of unique combinations or soil type and land use areas. To demonstrate the method's ability to select an effective BMPs for a watershed, a series of BMP scenarios were evaluated. The BMP scenarios were divided into three categories: a uniform application of a BMP throughout the watershed; a selective application of a BMP throughout the watershed and; the selective application of a set of BMP's throughout the watershed. Using a series of trial runs, the benefits of using the method were demonstrated. For example, similar results were obtained using a cropping BMP of "Corn, grain, soybean and cover" throughout the sample, and a ''no-till" BMP on 3 percent of the sample. This type of information was used by economic modelers to help target precious BMP implementation dollars. As an indirect result of the method's HRU development, it was possible to test the independence of each of the USLE factors within the Nansemond/Chuckatuck watershed. The results of the Duncan's Multiple Range Test shows an interdependence between the "soil type and the cover", "overland flow versus cover", and "overland flow versus soil type".

Resumen

Climate change may have detrimental effects on agriculture productivity (Challinor et al., 2009). At the same time, agriculture also plays a role in contributing to the causes of global warming (IPCC, 2009). The present research examined current agro-management practices of select agriculture management practices and products with a threefold objective, namely i) to understand the possible impact of climate change on crop yields, ii) to examine the carbon sequestration potential of select agricultural crops and management practices, and iii) to conduct a thorough life cycle assessment to estimate the carbon footprint of select agriculture crops and management practices, so as to help policy makers, planners and business managers in devising appropriate mitigation and adaptation policy frameworks and make sensible management decisions in the context of climate change. The research was conducted in a series of three studies. The first study investigated future corn and soybean yields in the Raccoon watershed in the US Corn Belt using projected climate data. This study used the Environment Policy Integrated Climate (EPIC) model to estimate the impact of climate change for 2015-2099 with data downscaled from eight atmosphere-ocean general circulation models (AOGCMs) with three emissions pathways reflecting low, medium and high greenhouse gas scenarios. Soil properties were gathered from the Soil Survey Geographic Database and data on crop rotation was derived from CropScape, a geospatial cropland data layer product of the US National Agricultural Statistics Service. Our findings show that 5-year averages of both corn and soybean yields for 2095-2099 depicted by all eight AOGCMs under low and medium carbon scenarios will increase in comparison to the 5-year average yields for 2015-2019. However, under the high carbon scenario, 5-year averages of both corn and soybean yields for 2095-2099 will decline in comparison to the 5-year average yields for 2015-2019 pointing to the effects of climate change. The study also examined the possible impact of carbon fertilization on yields. The results show that carbon fertilization of soybean, a C3 plant, may contribute to an increase in yield of 3% to 22% while its contribution to the growth of corn, a C4 plant, will be much lower. The second study focused on land-based carbon sequestration possibilities. Land-based carbon sequestration constitutes a major low cost and immediately viable option in climate change mitigation. Using downscaled data from eight atmosphere-ocean general circulation models for a simulation period between 2015 and 2099, the study examined the carbon sequestration potential of alternative agricultural land uses in an intensively farmed Corn Belt watershed and the impact of climate change on crop yields including impact on switchgrass. The results of the study show that switching from conventional tillage and continuous corn to no-till corn-soybean can sequester the equivalent of 192.1 MtCO2 eq of soil organic carbon per hectare with a sequestration rate of 2.26 MtCO2 eq ha-1 yr-1. The results also indicate that switchgrass can sequester the equivalent of 310.7 MtCO2 eq of soil organic carbon per hectare with a sequestration rate of 3.65 MtCO2 eq ha-1 yr-1. The findings of this research suggest that climate change does not have a significant effect on switchgrass yields, unlike on corn and soybean yields, possibly due to the carbon fertilization effect. As mentioned, agriculture can contribute to climate change mitigation efforts by providing low–land-based options through changes in agricultural management practices. A thorough life cycle assessment is necessary to compare various opportunities provided by a variety of agricultural approaches. The last study is a cradle-to-farm gate life cycle assessment of the contributions of select agricultural practices to mitigate global warming. The study focused on land-based practices including crop rotations instead of just individual crops. In the assessment, the study also included examinations of below-the-ground soil to determine the organic carbon sequestration potential of such practices, which most of the time is ignored in life cycle assessments due to lack of data. Specifically, the study examined three farming practices in the intensively farmed Raccoon watershed: continuous corn rotation with conventional tillage, corn-soybean rotation with no-till, and switchgrass. The assessment was conducted based on land units (hectares), instead of utilizing the usual practice of reporting life cycle assessment in product units, such as kilograms. The results of the life cycle assessment reveal that among the three agricultural practices, switchgrass has the lowest carbon footprint overall, and continuous corn rotation has the highest. Switching from continuous corn to switchgrass would reduce the overall greenhouse gases the most, by 6.30 Mg CO2eq/ha/yr, or by 62% compared to the emissions generated by the continuous corn rotation. Similarly, planting switchgrass instead of a corn-soybean rotation would reduce the overall emissions of greenhouse gases by 1.84 Mg CO2eq/ha/yr, or by 32% compared to the corn-soybean rotation. Finally, switching from continuous corn to the corn-soybean rotation would reduce overall greenhouse gases emissions by 4.46 Mg CO2eq/ha/yr or by 44% of the emissions generated by continuous corn. These findings can inform policy discussions on the potential of agriculture’s role in climate change mitigation.

Resumen

FundaÃÃo Cearense de Apoio ao Desenvolvimento Cientifico e TecnolÃgico
Esta tese apresenta uma pesquisa qualitativa sobre os processos educativos gerados na busca pela convivÃncia com o semiÃrido brasileiro- SAB. A proposta de convivÃncia com o SAB aponta o fracasso da lÃgica de combate Ã seca, como meio de fixar e integrar o SAB no contexto da NaÃÃo. Nela, o processo de rejeiÃÃo ao ecossistema presente na lÃgica do combate Ã seca, vem a ser substituÃdo por uma postura crÃtica de compreensÃo, com base numa relaÃÃo de respeito Ãs coisas, pelo que elas sÃo, pelo que possuem de intrÃnseco e que tenta e quer aprender e apreender a sua lÃgica interna. Portanto, parte-se do pressuposto de que Ã, alÃm de possÃvel, conveniente e pertinente conviver com a seca e com o SAB, atravÃs de vivÃncias e de prÃticas solidÃrias de educaÃÃo. E, embora haja o reconhecimento de que a proposta de convivÃncia nÃo esteja pronta, existe uma ideia do conjunto dos elementos que a compÃem e do sentido que compreende a proposta, cujo elemento fundante reside na unidade entre humanidade e natureza, explicitando a centralidade da relaÃÃo com a natureza como elemento organizador da vida social e de todo a sociabilidade no SAB. A educaÃÃo Ã considerada o elemento central e estruturante da proposta de convivÃncia com o SAB, em funÃÃo do seu alcance e poder de difusÃo ideolÃgico e cultural, que permite trabalhar a mudanÃa de leitura de mundo, de valores e de ideias de representaÃÃo social da natureza dominante. Paulo Freire nos lembra que se a educaÃÃo nÃo pode tudo, porÃm sem ela nÃo dÃ para pensar uma nova sociedade justa e equÃnime. E, se a escola ainda reproduz uma visÃo do SAB, apresentando-o como lugar inviÃvel, com precÃrias condiÃÃes de vida, ressaltando os preconceitos e os estereÃtipos em torno dele e de quem nele vive, ela Ã, tambÃm, um espaÃo privilegiado e lÃcus de construÃÃo do conhecimento. Pelo alcance que possui, pode propiciar uma reflexÃo no e sobre o universo escolar, que viabilize um novo diÃlogo sobre a relaÃÃo humanidade-natureza, tecendo, junto, o fio do novo paradigma para aprender, reaprender a viver e conviver no SAB. A pesquisa objetivou compreender como o projeto polÃtico pedagÃgico da Escola FamÃlia AgrÃcola Dom Fragoso, localizada no municÃpio de IndependÃncia, relaciona e incorpora os princÃpios e os fundamentos da proposta de convivÃncia com o semiÃrido da ArticulaÃÃo no SemiÃrido Brasileiro â ASA, na contextualizaÃÃo dos seus processos e prÃticas educativas. A experiÃncia educativa da Escola vem promovendo a ampliaÃÃo do espaÃo pÃblico para o debate polÃtico sobre a convivÃncia com o semiÃrido e a contextualizaÃÃo da educaÃÃo dentro dos princÃpios da pedagogia da convivÃncia com o SAB. A anÃlise dos resultados nos revela que os/as estudantes da EFA Dom Fragoso levam os saberes sobre a convivÃncia como uma dÃdiva a ser transportada, que, ao migrar, se espalha, vai para as escolas pÃblicas do campo, da cidade, vai para as comunidades, invade os sindicatos rurais, ocupa novos espaÃos e participa como um dos protagonistas da grande rede de relaÃÃes e de sociabilidade presentes, atualmente, no SAB. O semiÃrido pode ser interpretado como o lugar de todos nÃs, humanos e nÃo humanos, que habitamos o planeta Terra. A sua singularidade pode ser lida como uma metÃfora para se pensar um mundo novo, uma terra prometida e uma humanidade nova cujo trabalho da educaÃÃo e da pedagogia da convivÃncia nos leva a crer num futuro para esse forte, adorÃvel e velho planeta, desde que se consagre a celebraÃÃo do Contrato Natural.
This thesis presents a qualitative research about the educational processes generated on the search for coexistence with Brazilian semiarid â SAB. The proposal of coexisting with SAB points out the failure of the fighting dry climate logic as a way of fixating and integrating SAB in the context of the nation. In it, the process of rejection to the present ecosystem on the fighting dry climate logic gets replaced by a critical stand of comprehension, based on a relation of respect for things for what they are, for what they have of intrinsic that attempts to capture its internal logic. Therefore, it is assumed that it is possible, convenient and pertinent to live with dry climate and SAB, through experiences and solidarity practices of education. And, even thought it is recognized that the proposal of coexistence is not ready, there is an idea of the set of elements that compose it and of the meaning that conceive the proposal, which founding element lies on unity between mankind and nature, showing the centrality of the relation with nature as element that organizes social life and all sociability at SAB. Education is considerer the main and structuring element of the proposal of coexisting with SAB, because of its reach and power of ideological and cultural diffusion, which allows working the change of reading of the world, of values and of ideas of social representation of the dominant nature. Paulo Freire reminds us that education canât do everything, however, without it, a new fair and unanimous society cannot be conceived. And if school stills reproduces a vision of SAB, presenting it as an unviable place with precarious live conditions, highlighting the prejudice and stereotypes around it and those who live in it, it also is a privileged place and locus of construction of knowledge. By the reach that it possesses, it could propitiate a reflection at and about the scholar universe, which makes possible a new dialogue about the relation mankind-nature, weaving along the thread of the new paradigm to learn, relearn to live and coexist at SAB. The research objectified to understand how the political pedagogical project of FamÃlia AgrÃcola Dom Fragoso School, located on the city of IndependÃncia, related and incorporates the principles and fundaments of the proposal of coexisting with semiarid from the Articulation at Brazilian Semiarid â ASA, in the contextualization of its processes and educational practices. The educational experience of the school have been promoting the enlargement of the public space for political debate about the coexistence with semiarid and the contextualization of education according to the principles of pedagogy of the coexistence with SAB. The analysis of the results shows us that the students of EFA Dom Fragoso carry the knowledge about the coexistence as a gift to be carried that, as it migrates, it spreads to the public schools of the country, of the city, goes to communities, invades rural syndicates, occupies new spaces and participates as a main character of the large net of relations and of sociability that are present currently on SAB. The semiarid may be interpreted as the place for us all, human and nonhuman, that inhabit planet Earth. Its uniqueness may be read as a metaphor to think a new world, a promised land and a new mankind, whose work of education and of pedagogy of the coexistence leads us to believing in a future for this strong, lovely and old planet, as long as it is sanctified the celebration of the Natural Contract.

Soil erosion is one of the most important of today’s global environmental problems. Over the past few decades, soil conservation practices were implemented to reduce soil erosion in the United States. However, excessive sediment still remains among the most prevalent water quality problems. Agricultural fields and in particular ephemeral gullies (EGs) are considered to be a major contributor of sediment. The overall goal of this study was to improve modeling utility to identify and quantify sources of sediment. Specific objectives were: (1) to develop and demonstrate a method of field-scale targeting using Soil and Water Assessment Tool (SWAT) and to use this method as a targeted, flexible approach to pay explicitly for sediment-yield reductions; (2) to evaluate topographic index models (Slope Area [SA], Compound Topographic Index [CTI], Slope Area Power [SAP] and Wetness Topographic Index [WTI]) and a physical-based model (Overland Flow Turbulent [OFT]) in predicting spatial EG location and lengths. Black Kettle Creek watershed was the focus of an innovative project to pay for modeled field sediment reductions. An Arc-Geographical Information System (GIS) tool bar was developed that post processed SWAT hydrologic response unit output to field boundaries and prepared maps of high-priority fields by sediment, total nitrogen, and total phosphorus and was demonstrated to be useful for field-scale targeting. Calibrated SWAT model was used to establish baseline sediment yields. Various Best Management Practices (BMPs) were simulated and payments to implement each BMP for a given field were calculated. This study helped to guide determination of appropriate farmer support payments and quantified the important influence of BMP type and site-specific conditions for use in targeting conservation practice funding to achieve maximum soil-loss reductions per dollar spent. Extreme care should be used in selecting the source of spatial model input data when using SWAT for field-level targeting. Automated geospatial models were developed in a GIS environment to spatially locate and derive length of EGs using topographic index and physical based models. EG predictions were better for the SA model among the four topographic index models tested. Individual calibration of topographic index model threshold for each application site was needed. An OFT model (physical based model), which utilized topography, precipitation, soil, landuse/landcover and SWAT-based runoff estimates, did not need individual site calibration, and may have broader applicability than empirical based models.

Resumen

The effect of management practices used by smallholder farmers to improve soil quality and increase maize yield was examined in an 80 ha. micro-watershed of central Malawi. Because of the complexity inherent in smallholder farming systems, this research proposed the combination of participatory methods with analytical techniques developed in field ecology, such as multivariate and spatial analysis. During a Participatory Rural Appraisal (PRA), farmers identified factors potentially influencing soil quality and maize yield. One hundred and seventy-six (176) plots were located in twenty-nine (29) fields and characterized for management practices and biophysical characteristics. Soil samples were collected at each plot and analysed for a suite of properties. The maize yield was measured for both 1996--97 and 1997--98 seasons. A formal survey was used to gather information on household characteristics. Results showed that management practices that were promoted by a previous extension project, such as alley cropping and the planting of grass on contour ridges, were strongly correlated and found mainly in fields located closer to house compounds. Farmers with a higher proportion of their land under wetland gardens tended to use less agroforestry. Food security was associated with households that were able to purchase inorganic fertilizers, had larger landholding size, and owned livestock and woodlots. The effect of management practices on maize yield and soil quality was partially confounded with characteristics of the plot, such as slope, degradation level, number of years under cultivation or pest damage. Higher maize yield was observed in plots that were better managed, as expressed by the combination of different management practices, lower pest incidence, fewer erosion signs and higher soil fertility. Some positive effects of alley cropping on soil quality were observed in plots that were cultivated for a longer period and located on flatter land. This study demo

Resumen

Drainable porosity as a function of water table was investigated to replace the common practice of treating it as a constant A continuous function in the form of a negative exponential equation relating drainable porosity to water table depth was developed by three methods: (1) laboratory core-sample analysis; (2) rainfall rate and water table depth analysis; (3) drainage rate and water table depth analysis. Furthermore, this function was derived for four different water table regimes: (1) subsurface drainage; (2) low subirrigation and subsurface drainage; (3) high subirrigation and subsurface drainage; (4) no drainage and no subirrigation. The drainable porosity function was incorporated into a water balance model which simulated the soil moisture profile and the water table depth on a daily basis. Major modification of the previous model was the elimination of separate falling and rising water table equations since discrete porosity values were no longer assigned to particular soil depth intervals. A subroutine program which computed the total maximum transient storage and the transient storages to each of the four successive soil zones was also incorporated. The 'maximum drainable porosity' and the 'rate constant' parameters in the negative exponential equation were found to be different among the three methods of analysis and among the four water table regimes. Good agreement between simulated and actual water table depths of each regime for 1984 and 1985 was found. The modified water balance model could be used to generate different water table depths by changing the input parameter of design drainage rate. From these outputs, a appropriate drainage rate which gives the desired water table depth could be selected for the purpose of horizontal subsurface drainage system design.

Resumen

Debates over food security strategies in the Philippines have pitted the neoliberal paradigm of trade liberalization, export cropping, and chemical and biotech agricultural methods against the food sovereignty paradigm of protectionism, staple cropping, and sustainable agriculture methods.

The Philippine government has long pushed for yield increases of staples. However, there has been dissonance between governmental desires for rice self-sufficiency and pursuit of a more export-oriented agricultural economy. The World Bank, the International Monetary Fund, the Asian Development Bank, and the World Trade Organization have pressured the government of the Philippines to adopt various tenets of neoliberalism (trade liberalization, privatization, deregulation, and budgetary austerity), which have hindered the achievement of Philippine goals for self-sufficiency in its staple foods and stunted the potential benefits of land reform.

Through ethnographic research of the social and ecological conditions in three rural villages in the province of Bukidnon, this examination of agrarian change explores how various actors—small farmers, collectives, large planters, and agribusiness corporations—have been scaling their projects in the agricultural economy.

The use of chemical inputs has damaged soils and saddled farmers with debts. In many cases, control of land has been lost to elites through sales or pawning arrangements. Relatively egalitarian corn- and rice-farming areas have given way to a stratified landscape of sugarcane and banana plantations, as former smallholders have been forced to work as wage laborers. Multinational agribusinesses have steered the area away from staple production and threatened human and environmental health with pesticide exposure and erosion.

Some farmers though have organized against these prevailing trends. Production and social reproduction have been rescaled through collective marketing, reciprocal labor arrangements, and more equitably gendered divisions of labor. Agroecological methods, such as composting, organic fertilization, seed saving, and indigenous pest control have scaled the reproduction of environmental conditions more locally and increased farmer incomes because their inputs are created on the farm. Protecting local control of the means of production—seeds, fertilizers, and especially land—has become an important method for preserving a smallholder class, maintaining more self-determination, and working toward greater food sovereignty.
