Partimos da hipótese de que o município promove a atividade da moderna agricultura nessa região. A produção de commodities, em particular a soja, gerou centros urbanos que se emanciparam politicamente, originando a família de municípios do agronegócio, expressão concreta da necessidade do poder político da urbanização no front. Isso se deve ao fato do município no Brasil ser uma esfera do poder Estatal, ou seja, ele regula o território mediante criação de leis e organiza-o através de suas políticas públicas territoriais locais. Na família de municípios do agronegócio o poder político local direciona os investimentos para o uso corporativo do território. Os investimentos em fluidez e, mesmo a política local voltadas à população em geral, garante as condições para a racionalidade econômica do circuito espacial produtivo da soja, reforçando a especialização produtiva desses lugares. Dessa maneira, o município apresenta-se frágil frente à ação dos agentes hegemônicos do mercado global. A família de municípios do agronegócio constitui pontos luminosos no território, revelando a imposição da competitividade entre os lugares, uma vez que fora criada para dotar o território com normas e objetos técnicos orientados à atividade produtiva de commodities. A federação brasileira oferece facilidades à expansão da produção capitalista ao privilegiar a competição, ao invés da cooperação entre os municípios / Abstract: The present thesis aims to understand the creation process of new borough in the agricultural front of the Mato Grosso state. We begin from the hypothesis that the borough promotes the activity of the modern agricultural in that region. The commodities production, at special the soya, generates urban centers that has became borough with self political administration, giving origin to the agribusiness family of borough, one concrete expression of the political power necessity of the urbanization in the front. This is due to the fact the borough in Brazil to be a sphere of the power state, i.e., it regulates the territory by creation of laws and organizes it with its local territory political publics. In the agribusiness borough family the local political power directs the investment for the corporative use of the territory. The investments in fluidity and, even local political for the general population, guarantee the conditions for the economical rationality of soya productive spatial circuit, reinforcing the productive specialization of those places. In this ways, the borough self-presents weak in front of the hegemony agent actions of the global sale. The agribusiness borough family constitutes bright spots in the territory, revealing the obligatory imposition of the competitiveness among the places, since it was created to endow the territory with norms and technical objects oriented to productive activity of commodities. The Brazilian federation offers facilities to capitalist production of the expansion, to favour the competition in stead of the cooperation among the borough / Mestrado / Análise Ambiental e Dinâmica Territorial / Mestre em Geografia

Uma análise da dinâmica das mudanças técnicas ocorridas no setor agrícola do Estado de São Paulo se faz necessária, uma vez que o desenvolvimento desse setor contribui de forma direta no crescimento econômico. Este trabalho teve como objetivo principal analisar e interpretar a dinâmica das mudanças na base técnica do setor agrícola do Estado de São Paulo nas últimas duas décadas e determinar fatores estratégicos para manter e aumentar a competitividade desse setor. Para a realização desta pesquisa a unidade de análise foi o Estado de São Paulo representado pelos seus 645 municípios, sendo selecionadas vinte e quatro atividades agrícolas, dentre às sessenta e quatro existentes no Estado, nas quais foram analisadas três variáveis: área plantada, produção e rendimento médio. Na primeira etapa da pesquisa essas três variáveis foram analisadas num período de vinte anos utilizando as técnicas de análise de componentes principais (ACP) e Análise de Cluster (AC). Na segunda etapa foram analisadas as respostas dos especialistas sobre as principais mudanças na base técnica das culturas e na terceira etapa foi realizada a integração dos resultados das etapas anteriores. Os resultados mostraram que no período estudado, das vinte e quatro atividades, sete tiveram aumento na produção, área plantada e rendimento médio e as mesmas foram responsáveis em 2009 por 96,23% do valor da produção agrícola do Estado. Quanto à mudança na base técnica ocorrida nos últimos vinte anos, a inovação biológica representada pelo desenvolvimento de novas variedades foi o principal elemento da mudança na base técnica da agricultura paulista. A inovação mecânica representada pelas soluções em mecanização agrícola voltadas para o plantio, a colheita e a pós-colheita das culturas também contribuiu nessa evolução. Os fatores estratégicos apontam para manutenção e aumento nos investimentos para pesquisa de inovações biológicas representadas por novas variedades e a pesquisa em inovações mecânicas representadas pela mecanização agrícola / Abstract: The technological evolution development in world's agriculture, particularly in Brazil led to changes in the structure and functioning of agribusiness systems, resulting in a new organizational dynamics that is based on some key factors such as specialization and flexibility. An analysis of the dynamics of technical change occurred in the agricultural sector of the State of São Paulo is necessary, since the development of this sector contributes directly to economic growth. This study aimed to analyze and interpret the dynamics of changes in the technical base of the agricultural sector of the state of São Paulo in the last two decades and determine strategic factors to maintain and enhance the competitiveness of this sector. The unit of analysis of this research was the São Paulo State represented by its 645 municipalities, where twenty-four agricultural activities were selected among the sixty-four being explored in the State with three variables analyzed: area planted, production and average yield. In the first stage of the research these three variables were analyzed over a period of twenty years using the techniques of principal component analysis (PCA) and Cluster Analysis (CA). In the second step the responses of experts on major changes in the technical base of crops were analyzed and the final step was the integration of the previous results. The results showed that during the study period, seven of the twenty-four activities had increases in production, acreage and average yield and these seven activities accounted in 2009 for 96.23% of the value of agricultural production in the state. As for the change in the technical base within the last twenty years, the biological innovation represented by the development of new varieties was the main element of change in the technical base of Sao Paulo's agriculture. The mechanical innovation represented by agricultural mechanization solutions focused on planting, harvesting and post-harvest operations also contributed in this evolution. Strategic factors point out to the need of increased investment and maintenance for biological research innovations represented by new varieties and research in mechanical innovations represented by agricultural mechanization / Mestrado / Planejamento e Desenvolvimento Rural Sustentável / Mestra em Engenharia Agrícola

Determinants of smallholder maize farmer's varietal choice : a case study of Mogalakwena Local Municipality Limpopo Province, South Africa

Makwela, Mokgadi Angelina January 2021 (has links)
Thesis (M. A. Agriculture (Agricultural Economics)) -- University of Limpopo, 2021 / Maize seeds differ according to varieties.The traditional maize varieties(also referred to as (Landraces)are maize varieties that have been cultivated and subjected to selection by farmers for generations.They retain a distinct identity and lack formal crop improvement. Improved maize varieties,on the other hand,are bred with characteristics such as drought and disease tolerance. This research was conducted to determine the attributes preferred by farmers when making a maize varietal choice.To be specific, the study aimed to achieve the following objectives:(i) Identify and describe socio economic characteristics of smallholder maize farmers’ in Mogalakwena Municipality; (ii) Analyse socioeconomic characteristics of smallholder maize farmers in Mogalakwena Municipality; (iii) Identify different maize varieties grown by smallholder farmers in Mogalakwena Municipality,and (iv) determine and analyse factors influencing farmers’choice ofa maize variety. Descriptive statistics and the Multinomial Logistic Regression Model were used for data analysis.The results of the study revealed that 64% of the respondents had formal education.This meant that they have the capability to grasp more information, if provided with trainings. It was found that 75% of the farmers did not have access to extension service which is supposed to play a significant role in agricultural information dissemination.The most grown maize variety was land race varieties which constituted 59.5%. This percentage was said to be resultant from limited access to the seed market. Infact,80% of the farmers had to travel an average of 42 kilomteres to access the market which also had a limited number of varieties.The Multinomial Logistic Regression Model revealed that only 5 variables (Educational level, farm size, yield, extension contact and knowledge of maize varieties )were significantat1%,5%,1%,1% and1%, respectively.The majority of farmers were old people with little access to extension service and an inadequate farming knowledge which lead to a highper centage of farmers continuing to grow landrace varieties. Based on the findings, this study recommend further research on attributes that influence farmers varietal choice and Government intervention in provision for resources and development of existing and new infracstrcture to encourage extension service delivery.

Impacts of new agricultural technologies in Peru

Walters, Edward B. January 1986 (has links)
The purpose of this study was to evaluate the impacts of Peru's research and extension programs on two regions in Peru and assess the implications of those impacts on institutional action by the Agrarian Bank and the Peruvian research and extension service. An LP model was constructed for two regions, Contumaza and Tarapoto, and was run under various levels of risk, alternative credit arrangements, selected price changes, and with and without the newly released varieties. Results from the various scenarios demonstrated that the introduction of new varieties increased net income, labor use, and the demand for credit in both regions. Also, altering the amount of credit available had a much more significant impact on the regions than altering the interest rate. / M.S.

Conceptualizing technological change: technology transfer in the green revolution

Parayil, Govindan 23 August 2007 (has links)
Technological change, and technology transfer as an aspect of this process, is examined by providing a comparative assessment of models of this phenomenon from economics, history, sociology, and neo-Schumpeterian-evolutionary studies. The Green Revolution, which is used as the empirical basis for testing these models, is generally referred to as the change in agricultural technology observed in some Third World countries in the 1960s and 70s as a result of the transfer of high-yielding varieties (HYVs) of seeds and a new culture of agricultural practice resulting in high productivity of the land. It is found that most of the examined models of technological change do not completely account for this process. It is argued that technological change should be conceptualized as a process of knowledge change. Artifactual change, which the examined models accentuate, should be viewed as the manifestation of the knowledge change at a secondary level. With the Green Revolution as the empirical basis, arguments are presented for a comprehensive model of technological change within the framework of "technology as knowledge." / Ph. D.

The influence of entrepreneurial and market orientations on small scale agricultural enterprises in the Vryburg region

Agbobli., Edem Korku January 2013 (has links)
Thesis (D. Tech. (Business Administration )) - Central University of Technology, Free State, 2013. / A major concern for developing countries including South Africa is the high levels of unemployment, poverty and inequity. Developing countries have accordingly been pre-occupied with finding solutions to these problems. Drawing on the success of small, micro and medium enterprises (SMMEs) from the developed countries such as the US and the UK, developing nations have embraced the idea of promoting development through SMMEs. But the overall performance of the small business sector in most developing countries has rather been dismal and as such have not been able to contribute optimally to the development agenda. Adopting a strategic management perspective, this study hypothesised that an integration of entrepreneurial orientation (EO) and market orientations (MO) glued together by innovativeness (INNO) would yield superior outcomes than the stand-alone effects of these strategic postures. To test the hypothesis, a sample of 198 small scale agricultural enterprises (SSAEs) in the Vryburg region was surveyed. Descriptive and inferential statistical analyses were performed on the data generated. The empirical findings showed that EO + MO + INNO interactively exhibited positive and significant correlation with the performance (sales growth and profitability) of SSAEs in the Vryburg region. However, the inter-correlations of EO + MO + INNO with business performance were practically moderate. The moderate correlations create opportunities for strengthening the entrepreneurial and market orientations and innovativeness of SSAES and in fact small businesses in general. An intensive and co-ordinated intervention of government and NGOs in transforming the small business sector into the real engine of growth of the economy is imperative. The study also attempted to predict firm performance holding EO + EO + INNO as predictor variables. Multi linear regression and multinomial logistic regression analysis however did not yield significant predictions of performance of SSAEs. This outcome provides a launch pad for further research into the proposed model in different settings because this study was mainly exploratory and executed in a rural and agricultural environments. Notwithstanding, the study made important contributions to the literature. It showed that it was possible to integrate EO + MO + INNO (previously viewed by many authors as exclusive constructs) into a single business model for the synergic enhancement of small business performance. It is hoped this would stimulate economic growth and development especially in developing countries.

Assessing the impact of sustainable farming techniques on smallholder farm enterprises in Zimbabwe

Masunda, Fanuel 04 1900 (has links)
Thesis (MPhil) Stellenbosch University, 2014. / ENGLISH ABSTRACT: The aim of this thesis was to investigate if the Conservation Agriculture (CA) project being implemented by Zimbabwe Farmers Alliance Trust, a non-governmental organisation, has improved the livelihoods of participant farmers. The research was done in the Mazowe, Chiweshe area where the organisation has been working with farmers with the key objectives of improving food security, livelihoods and stabilising production for the rural households. The research also looked at production trends and adoption levels of CA in the area. Yields were viewed as an important element since food security of rural communities is constantly under threat because of droughts. A key element of the thesis was primary research done in Mazowe Chiweshe Ward 4, where farmers were interviewed to get information on their experiences with the CA project. The study was informed by both primary and secondary data. A literature review was conducted to give a background on sustainability and multifaceted problems facing the globe; dubbed as a polycrisis. In order to assess the impact of the project, a framework was developed to define sustainability at global level and also at small-scale farmer level. The Sustainable Livelihoods Approach framework was used as the assessment tool that looks at capital assets as given by Conway and Chambers. The framework goes beyond financial gains and looks at capabilities, assets and activities required for a means of living. The CA project was thus assessed according to this framework as a yardstick for improvement of livelihoods in the area. Primary data was gathered from a sample of 25 farmers randomly selected from a total of 250 farmers involved in the project under ZFAT. The data was gathered through questionnaires, key informant interviews and participant observation techniques. With regards to the adoption of CA and its principles, the research suggested that farmers are eager to practice sustainable agriculture, but the scale of the project is too small to expand the project to more than the 250 farmers already in this project. It was also found that non-governmental organisations have played a significant role in introducing sustainable farming and that the government now need to step up efforts in supporting the projects. The study concluded that the CA project has improved livelihoods and is helping to stabilise production through sustainable land use and advanced farm management practices. The project has not only benefited the direct project beneficiaries or key participant farmers but also the environment as soil fertility is improving and biodiversity is being protected and enhanced. The programme has managed to create a mind-set in the community that; what we have today is a result of the way past generations operated and that we should feel challenged to leave behind a better-managed and flourishing environment for the next generation. This was concluded as a significant number of farmers in the interviews showed that they have changed perceptions since joining the project. The study concluded with recommendations for up-scaling of the project as well as the need for collaboration between relevant stakeholders. This would promote projects of similar nature that promote sustainability and sustainable livelihoods. However, the case study was specific to the Mazowe Chiweshe area and the findings presented in this thesis cannot be viewed as representative of the larger smallholder farming sector though it may provide relevant and positive pointers for similarly beneficial projects to be implemented elsewhere. / AFRIKAANSE OPSOMMING: Die doel van hierdie tesis was om te bepaal of die bewaringslandbouprojek van die nie-regeringsorganisasie Zimbabwe Farmers Alliance Trust (ZFAT) die deelnemende boere se lewens verbeter het. Die navorsing is in die Mazowe Chiweshe-gebied onderneem, waar die organisasie boere bystaan om landelike huishoudings se voedselsekerheid en lewensgehalte te verbeter en landbouproduksie te stabiliseer. Die navorsing het ook aandag geskenk aan produksietendense en die vlakke van aanvaarding van bewaringslandbou in die streek. Opbrengste is as ’n belangrike element beskou, aangesien droogte voortdurend die landelike gemeenskappe se voedselsekerheid bedreig. ’n Kerndeel van die tesis was primêre navorsing wat in Wyk 4 van Mazowe Chiweshe onderneem is, in die vorm van onderhoude met boere om inligting in te samel oor hul ervarings van die bewaringslandbouprojek. Die studie is deur sowel primêre as sekondêre data gerig. ’n Literatuuroorsig is onderneem vir agtergrond oor volhoubaarheid, sowel as oor die veelsoortige probleme waarmee die wêreld te kampe het en wat as die ‘polikrisis’ bekend staan. Om die impak van die projek te beoordeel, is ’n raamwerk ontwikkel om volhoubaarheid op algemene sowel as kleinboervlak te omskryf. Conway en Chambers se ‘volhoubare bestaan’-benadering is as assesseringsinstrument gebruik om kapitaalbates te beoordeel. Die raamwerk strek egter verder as finansiële gewin en ondersoek ook die vermoëns, bates en aktiwiteite wat nodig is vir ’n volhoubare bestaan. Aan die hand van hierdie raamwerk is daar dus beoordeel tot watter mate die bewaringslandbouprojek plaaslike mense se lewens verbeter het. Primêre data is ingesamel uit ’n steekproef van 25 boere wat aan die ZFAT-projek deelneem. Die data is met behulp van vraelyste, onderhoude met sleutelinformante sowel as deelnemerwaarnemingstegnieke bekom. Wat die aanvaarding van bewaringslandbou en die beginsels daarvan betref, toon die navorsing dat boere gretig is om volhoubare landbou te bedryf, maar dat die skaal van die projek te klein is om meer as die bestaande 250 boere in die projek te help. Daar is ook bevind dat nie-regeringsorganisasies ’n beduidende rol gespeel het in die inwerkingstelling van volhoubare boerdery, maar dat die regering nou sy pogings ter ondersteuning van die projek moet versterk. Die studie kom tot die gevolgtrekking dat die bewaringslandbouprojek, deur volhoubare grondgebruik en gevorderde bestuurspraktyke, lewensgehalte verbeter en produksie gestabiliseer het. Nie net die deelnemende boere het by die projek baat gevind nie, maar ook die omgewing, aangesien grondvrugbaarheid verbeter en biodiversiteit beskerm en versterk word. Die studie sluit af met aanbevelings oor die uitbreiding van die projek, sowel as die behoefte aan samewerking met tersaaklike belanghebbendes. Dit sal ander soortgelyke projekte vir volhoubaarheid en ’n volhoubare bestaan bevorder. Tog het die gevallestudie bepaald op die Mazowe Chiweshe-omgewing betrekking gehad en kan die bevindinge in hierdie tesis nie as verteenwoordigend van die groter kleinboersektor beskou word nie. Nietemin kan dit relevante en positiewe wenke bied vir soortgelyke voordelige projekte wat elders in werking gestel word.
