For many poor rural South African communities, involvement in agriculture remains one of their most secure livelihood strategies. For the majority of these people, indigenous knowledge and the use of local materials, resources and skills is often the only asset they possess. The Ezemvelo Farmers Organisation (EFO) from the community of Embo in KwaZulu-Natal is one such group of rural people befitting this description. In the absence of financial resources to purchase relatively expensive agricultural inputs, accompanied by a lack of infrastructural development in their community, EFO farmers have become organic farmers by default. EFO members produce mainly traditional organic crops. However, little has been documented about the potential value of trade in these products. The purpose of this study was to explore potential marketing opportunities for traditional organic products through the mobilisation of indigenous knowledge, skills, and natural resources to improve the livelihoods of EFO members. A research team of three postgraduate students, each involved in his/her own independent study, worked in collaboration to collect relevant research information. Five data collection tools were used to collect this information. These were a household survey, a sustainable livelihoods analysis, a forcefield analysis, a stakeholder analysis, and a workshop. Research results showed that there are five stakeholders involved in EFO activities, each with his/her own personal interests. EFO members mainly produce amadumbe, sweet potatoes, and potatoes, which they market to a packhouse, the local community, and to hawkers. Other crop varieties are produced for household consumption and small quantities are sold to the local community and hawker markets. Farmers obtained a slightly higher price for crops sold to the packhouse as compared to the other two markets. The packhouse was the farmers' largest market for the 2002 season. However, the packhouse market was unsustainable for farmers because of problems due to the delays in payments for produce, the high quantities of crops that are rejected because they did not meet the quality control standards of the packhouse, and problems due to the unreliability of transport from Embo to the packhouse. The majority of EFO members' farms were also found to be unprofitable due to the high costs of inputs and losses to production. Constraints such as a shortage of kraal manure for soil conditioning, unfenced properties, a lack of water for irrigation, and the unavailability of a tractor for ploughing were found to be contributing factors to the unprofitability of member farms. Recommendations for improving marketing and profitability were that projects involving farmers should be regularly evaluated, EFO members seek business management skills, direct contracting agreements with their suppliers, explore value added products, and for Government to play a role for rural enterprise development to take place. / Thesis (M.Sc.)-University of Natal, Pietermaritzburg, 2002.

This thesis investigates challenges to promoting socially just, locally focused agriculture faced by the organic certification program that now regulates organic farming in British Columbia. This inquiry into how organic certification works is conducted as an institutional ethnography. Institutional ethnography is the methodological foundation of Dorothy Smith’s feminist sociology for people. For the institutional ethnographer, ordinary daily activity is the site for investigation of social organization. Small scale organic farmers who are committed to sustainable, socially and ecologically just agriculture offer a critical standpoint from which to explicate extra-local text mediated ruling relations. This inquiry draws on data from open-ended interviews with farmers and an independent organic certification inspector. From these accounts I begin to address how it is that BC’s organic farming certification program actually enters into and reconstitutes the everyday work of farmers and inspectors. From my findings I argue that corporate interests and a focus on global free trade in organic produce and products increasingly guide the institutional structure of organic certification programs. This in turn moves organic farming out of local, farmer control.

This theses fokus on the enviromental impact of livestock raising cycle (cattle, pigs and poultry). Energetical costs and emissions caused by livestock fattening are counted including processing and transport of the final product ? meat. Conventional and organic farming were compared as well as different forms of housing. SIMA Pro software tool was used for obtaining the emission load. The aim of the work was to find which form of livestock raising has the least environmental impact. This work was created in the European Union internatiponal project M00080-EUS-AT-SUKI Sustainable Kitchen focusing on the emission load of substantial links of vertical production chain.

The focus of this study is to explore and expand farmer learning processes in sustainable agriculture workplace contexts. It examines change oriented learning processes in the context of three sustainable agriculture practices. The study begins by discussing the history and emergence of environmental discourses and approaches; sustainable agriculture; and the histories of three kinds of sustainable agriculture practices: Permaculture, Organic Farming and Machobane Farming System. It also traces the evolution of agricultural extension approaches within the wider context of education for sustainable development. The main focus of the study is an exploration of how farmer learning can be mediated through an expansive learning process. The study methodology surfaces some of the contradictions in sustainable agriculture and learning activity systems that farmers encounter in learning and practising sustainable agriculture. It uses these contradictions as sources of expansive learning in and between the respective activity systems of farmers, sustainable agriculture facilitators, agricultural extension workers (conventional) and organic entrepreneurs. As shown in the study, the expansive learning processes result in the modelling, implementation and reviewing of solutions to contradictions being faced in the learning and practice of sustainable agriculture. The study also proposes a number of tools that can be adapted and used by development farmers and agricultural trainers to examine and expand learning as well as build farmer agency. The study was conducted in three case study sites in Lesotho, South Africa and Zimbabwe. In Zimbabwe the study is located in Hwedza district in the St Margaret Primary School and community that learn, practise and facilitate the learning of Permaculture within the Schools and Colleges Permaculture Programme (SCOPE). The second study site is in South Africa: Durban urban and peri-urban areas where a community of organic farmers, facilitators and entrepreneurs coordinate the marketing of their produce through Isidore Farm and Earth Mother Organic and support each other to learn and practise organic farming. The third study site is based in the Mafeteng and Mohale‟s Hoek districts of Lesotho where the focus was on farmers who learn and practise the Machobane Farming System (MFS) and are supported in this by the Rural Self Development Association (RSDA) and the Machobane Agricultural Development Foundation (MADF). Drawing on three sensitising concepts of dialectics, reflexivity and agency, the study worked with Cultural Historical Activity Theory (CHAT) underpinned by critical realism to reveal how farmer learning is mediated and expanded. The theory of practice/habitus also provided a useful theoretical lens with which to examine data generated. Using a two-phased, multiple embedded case study approach, the study worked within the broad framework of social learning. It used semi-structured individual and group interviews, observations and document analysis to explore learning processes and generate „mirror‟ data. This data was then used in Change Laboratory Workshops, within the Developmental Work Research methodology, where double stimulation and focus group discussions contributed to expanding learning processes. Drawing on critical realism the study used inductive, abductive and retroductive modes of inference to analyse data in each case study as well as across case studies. The findings of the study reveal that farmer learning is influenced by both intrinsic motives, such as identity, and extrinsic motives which are primarily associated with economic, ecological and health benefits. Farmers learn through scaffolding and mediating tools that link everyday and scientific knowledge. They also learn from fellow farmers through observation, practising and experimentation. Some of the issues that were raised in connection with farmer learning processes are: language; time to learn, practice and appropriate concepts; time to improve the natural resource base while at the same time improving income generation; and responses to climate change. The study also found that farmer learning and practice of sustainable agriculture in the case studies investigated, is influenced by past and current agricultural and educational policies; societal values and attitudes; social and cultural backgrounds; work affordances and gender relations; quality of training offered; poverty; and, HIV and AIDS. In the second phase of the study, which built on the problematic situations being encountered by research participants (sustainable agriculture farmers, sustainable agriculture facilitators, extension workers, and organic marketers) to surface contradictions, the main finding was that the expansive learning process has potential to enhance farmer learning and practice of sustainable agriculture. It does this by mobilising distributed cognition among participants as well as their preparedness to act. Through the expansive learning processes in each case study, research participants were able to question their practices, surface contradictions, model solutions and implement them, and thus build individual, collective and relational agency reflexively. Observation of this required micro-analysis of agentive talk and reflective talk. The study contributes in-depth insight into participatory research and learning processes, especially within the context of people-centred learning and innovation in the agricultural development arena. It provides empirical and explanatory insight into how change oriented social learning can emerge and be expanded in Education for Sustainable Development, explaining learning and change relationships in three sustainable agricultural practices. It also provides learning and extension tools to work with contradictions that arise from intentionality, experience, context and history in farming and training activity systems. Its key contribution lies in providing in-depth insight into mobilisation of human agency and reflexivity in change oriented sustainable agriculture learning and development, processes that are critical for responding to contemporary socio-ecological issues and risks.

Depuis une perspective théorique au croisement de la sociologie économique et de la sociologie de la connaissance, cette thèse a pour objectif d’examiner les mécanismes sociaux à l’œuvre au moment de la conversion vers l’agriculture biologique. Sur la base de l’étude empirique et de l’analyse d'un réseau complet qui révèle les interdépendances entre plus de 60 viticulteurs certifiés ou en cours de certification à l'agriculture biologique en Côte de Beaune, sont analysés les processus d’apprentissage collectifs sur lesquels s’appuie cette transition. Cette thèse montre l’existence de deux processus-Type d’apprentissage qui se définissent en fonction des frontières des groupes de référence (ou niches sociales) ; elle analyse le rôle des pionniers du milieu étudié comme pivot de l’action collective dans ces deux processus d’apprentissage, et explore enfin les régularités qui structurent les échanges au sein du milieu. Ces régularités permettent de constater que les viticulteurs intègrent dans leur raisonnement des aspects identitaires qui différencient les viticulteurs bio « de la première heure » des novices, au-Delà d'aspects économiques liés à une tendance à la « coopétition ». / This PhD dissertation combines the approaches of economic sociology and sociology of knowledge in order to analyze the social mechanisms underlying the conversion into organic farming. Based on an empirical study and analysis of a complete social network describing the interdependencies among over 60 wine producers certified in organic farming or in the process of getting the official certification in French Côte de Beaune, this research analyzes the collective learning process on which this transition relies. The thesis proves the existence of two types of learning process, which are defined by the social borders of reference groups (or social niches); it analyzes the key role of pioneers of the social milieu in both learning processes and studies the regularities structuring social exchanges. These regularities allow us to confirm that wine producers take into account in their reasoning both the identity aspect related to their conversion to organic farming and their economic position, in a trend towards “coopetition”.

The aim of this thesis is processing ÚZEI data for organic agricultural production in individual regions of the Czech Republic in the form of maps and graphs that provide a basic overview of the territorial deployment of crop and livestock production of organic farming. For crop production are given the following information: sown area in the conversion period and in the full organic mode, organic production and the average yield. Data of livestock in organic farming provide information about the numerical status of the individual categories of livestock. Part of the thesis is also devoted to the realization of crop and livestock organic products on the market in 2012. The thesis is part of the project Gaju 019/2013 / S.

Identifier les leviers permettant de stimuler la régulation naturelle des bioagresseurs tout en préservant la biodiversité est indispensable pour concevoir des paysages agricoles fonctionnels. A partir d’une méta-analyse et d’une étude empirique reposant sur 42 parcelles viticoles localisées dans Nouvelle Aquitaine (France), nous avons cherché à évaluer l’impact du déploiement de l’agriculture biologique à de large échelles spatiales sur 1) les communautés d’ennemis naturels, 2) les services de régulation naturelle, 3) les taux d’infestation par les bioagresseurs. Dans ce travail, nous avons montré que la proportion d’agriculture biologique est un facteur structurant plus les communautés d’ennemis naturels que la proportion d’habitats semi-naturels dans le paysage. De plus, nous avons montré que les communautés de bioagresseurs rencontrées dans les vignes ne sont pas influencées par la proportion d’agriculture biologique alors qu’elles répondent plutôt négativement à la proportion d’habitats semi-naturels. Par ailleurs, nous avons montré que l’agriculture biologique, à l’échelle globale et indépendamment du type de culture considérée est un système de culture stimulant la régulation naturelle des bioagresseurs. En viticulture, elle permet de réduire l’utilisation des produits phytosanitaires, comparé à l’agriculture conventionnelle. Enfin, nos analyses ont révélé qu’au-delà de la différence de systèmes de culture, un certain nombre de facteurs locaux (e.g., âge des parcelles, fréquence de traitements, productivité) permettent d’expliquer la structure des communautés d’ennemis naturels et des services de régulation naturelle des bioagresseurs. Tout en produisant des connaissances sur les processus permettant d’expliquer les assemblages des communautés d’ennemis naturels et les niveaux de services de régulation rendus, notre travail suggère des pistes pour l’aménagement des paysages viticoles permettant de concilier préservation de la biodiversité et maximisation des régulations naturelles. / Identifying landscape context and farming systems that enhance natural pest control while maintaining biodiversity is crucial to design functional agricultural landscapes. Using a meta-analysis and an empiric study based on 42 vineyards in Nouvelle Aquitaine (France), we investigated the effect of the deployment of organic farming at a landscape scale on 1) natural enemy communities, 2) natural pest control and 3) pest infestation levels. Here, we showed that the proportion of organic farming structured more natural enemy communities than the proportion of semi-natural habitats. On the opposite, pest and pathogen infestations were never influenced by the proportion of organic farming while they were negatively influenced by the proportion of semi-natural habitats. Furthermore, at a global scale and for every crop types, organic farming, per se, enhances natural pest control. In viticulture, it is less dependent of synthetic agrochemicals than conventional farming. Moreover, local factors such as the treatment frequency index, the field age and the crop productivity had important effects on natural enemy communities and natural pest control. Finally, we yielded knowledge on processes that impact natural enemy assembly and natural pest control in agrosystems. For vineyards-dominated landscapes, our work suggests some tracks for landscape planning that support biodiversity conservation and natural pest control.

The thesis is focused on the evaluation of current situation of farming and making a plan for a transition of Angus farm to an organic way of farming in plant and stock farming. During the period of conversion that takes 2 years for arable land, meadows and grazing the farmimg has to be in compliance with the law No. 344/2011 about organic farming. The theoretical part contains basic information about organic farming history in the Czech Republic, basic concept specification such as organic farming, ecofarm, organic product, organic food. The other information deal with the main goals of organic farming, legislation, check, certification and last but not least the subsidy of organic farming. The second part of the thesis analyses the current situation of the farm where the plant farming structure, stock farming structure, used machinery and agrotechnological operation, staffing, balance of nutrients, balance of forage, chemical means using, and SWOT analysis of the current situation are described. In the final part of the thesis there is offerred the structure of plant and stock farming for the conversion where balance of nutrients, balance of forage, staffing, operation modernization, introducing the agritourism, economic evaluation and SWOT analysis of the current situation after the conversion are described.

The aim of thesis was to analyze the South Bohemian organic dairy production and distribution of organic milk. The thesis focuses on farm production, distribution channels and the application of the regional market. Through the processing of data from the database of the Institute of Agriculture Economics and Information and a questionnaire survey conducted at the level of organic farmers farming in the South Bohemian Region with a valid certificate for the milk production was assessed the development and the current market situation of organic milk production in the South Bohemian Region.
