The thesis examines how resource-poor smallholder farmers in Mexico are integrated into a Global Value Chain. Most Global Value Chains depend on production located in developing countries. In agriculture, Global Value Chain tend to concentrate production in large enterprises and exclude smallholder farmers. The logic of Global Value Chains is to reduce the cost of production by allocating low value activities, such as production of commodities to developing countries to take advantage of cheap labour cost. High value activities such as branding, marketing and product development remain in high income countries. The thesis consists of the in-depth case study of San Francisco Produce/Peninsula Organics (SFP/PO) Global Value Chain. It is located throughout Southern Baja Peninsula in Mexico and San Francisco California, U.S.A. It sells organic certified produce to the American market, particularly California and east coast. SFP/PO was founded by a social entrepreneur and has been functioning for over 30 years. This Global Value Chain has an explicit social purpose. It focuses on integrating smallholder farmers into agricultural production. This value chain requires farmers to adopt organic production. The methods consisted of semi-structured interviews. In total, 50 interviews were conducted in Mexico to farmers that belong to the value chain in 9 co-operatives and 3 single farmers. The interviews focused on how farmers learned organic production to meet quality requirements of global buyers. The analysis uses three perspectives to explain the integration of smallholder farmers into SFP/PO and the development of organic production capabilities. First Global Value Chains are used to describe the network, connections and production activities smallholder farmers and global buyer carry out. The study sheds light on how the value chain achieves its social aims by using global markets and providing external inputs to improve farmers' livelihoods. Second, using Technological Capabilities the study explains the skills farmers need to develop to participate in the value chain. Third, a Communities of Practice perspective is used to explain how social learning is involved in developing production capabilities. The research explains how farmers collectively define competence and how they display three different levels of participation in the value chain, periphery, medium and full participation. And fourth, using the theory of Knowing in Action, the research explores co-learning between novice and expert farmers and the interactions among farmers that results in co-innovation to develop new technical solutions and crop varieties. The thesis presents a case of a value chain which is motivated by social purpose to improve livelihoods of smallholder farmers. The study demonstrates that there is a change of ethos, where global value chain integrates farmers into agricultural production. These data highlight the importance of social structures which allow farmer-to-farmer connections which enhance novice farmer skills enabling interactions where there is respect, and negotiation of knowledge. These interactions take indigenous farmers' knowledge into account in ways that can be acknowledged and harnessed in the form of practices and techniques to produce globally marketable products.

This project examines whether there is a direct link between respiration and the rate of senescence of fresh produce. Treatments that increase the storage life of fresh products, such as cooling, modified atmospheres and semi-permeable coatings, often decrease respiration rates. This suggests that it may be possible to assess the effectiveness of a specific storage treatment in terms of its effect on reducing respiration. If this is so, total respiration during storage should sum to a constant regardless of changes in the storage conditions. Such an equivalence between 'respiration life' and storage life has been demonstrated in only a few cases. Respiration data from a wide range of published work was analysed from the viewpoint of testing this hypothesis. In general, the results were positive, with some reservations that were further investigated by experiment. In conclusion, respiration rate may be a guide to storage life for products that have clearly defined stages of senescence, and for which rots are not the primary cause of the end of acceptability. The development of the respirometer should make it possible to examine this relationship for many other commodities. However, while respiration may be a function of the rate of senescence under some circumstances, it is also affected by other factors. These include photosynthesis, attachment to the plant, and permeance to gases. Directions for future work therefore include the contribution of photosynthesis to fruit development, the effects of ethylene on respiration rates of non-climacteric fruit while attached to the plant, and interactions between ethylene synthesis and disease resistance / Doctor of Philosophy (PhD)

The 48 members of the Ezemvelo Farmers' Organisation (EFO) in KwaZulu-Natal (KZN), South Africa (SA), that were fully-certified as organic farmers were surveyed during October-December 2004 to assess their perceived level of satisfaction, trust, cooperation and commitment in a formal supply chain producing amadhumbes (a traditional vegetable tuber), potatoes and sweet potatoes for a major SA supermarket group. Empirical recursive models show that a high level of satisfaction in the working relationship results in these farmers trusting the pack-house agent more. High levels of trust, in turn, lead to higher levels of both commitment to, and cooperation in, the supply chain. A simultaneous-equation model showed that EFO farmers with higher levels of commitment tend to be more cooperative, and that members with higher levels of cooperation tend to be more committed toward the working relationship. These results suggest that strategies to improve the working relationship with the pack-house agent need to promote satisfaction, trust, cooperation and commitment. For example, co-investment in better crop storage facilities at farm-level would promote satisfaction and hence trust. There is also scope for more cooperation in the planning of new organic crop products to grow and market, and to remove some price uncertainty by giving EFO farmers more information about prices that they will be paid by the pack-house agent in this supply chain. In addition, satisfaction and, hence, trust, cooperation and commitment may be improved by adopting a formal contract between the EFO farmers and the pack-house agent to replace the current, incomplete verbal contract that governs trading. Some issues that may be addressed in this contract are improved communication systems via regular meetings, renegotiations of trading terms so that farmers can benefit from positive changes in organic crop prices; guidelines for paying farmers more quickly by the pack-house agent; mechanisms to trace crop quality to a specific farmer to avoid free riding; and penalties for breaching the contractual arrangements. The 48 EFO farmers were also asked to give their perceptions of the main constraints on organic crop production and marketing in the formal organic crop supply chain. They perceived that uncertain climate, unavailability of tractor or draught power when needed, delays in payments for crops sent to the pack-house, lack of affordable inputs (particularly labour and manure), a lack of cash and credit to finance inputs, lack of affordable transport to market crops, more work than the family can handle, a lack of manure to purchase; and a lack of crop storage facilities and telephones to negotiate sales as the current top 10 constraints. Principal Component Analysis summarized the underlying dimensions in the 20 constraints ranked by these farmers as indicating "lack of market information and lack of market power"; "crop production expansion constraints"; "commitment to crop area expansion"; "lack of liquidity"; "lack of proper storage facilities"; and "lack of information about alternative markets". Potential solutions to better manage these perceived constraints include: improved risk management practices (e.g., supplemental irrigation, water-harvesting and small boreholes), improving access to tractor services via improved tractor scheduling or using local contractor services, quicker pack-house delivery payments, improving quality inspection at the departure points at EFO farm-level to reduce crop rejection rates and "free riding" by producers of lower quality organic crops, more interaction with the retailer to promote sales of organic crops, providing advice on how the EFO farmers can improve their bargaining power, and providing more information (e.g. crop prices) about other organic markets and changing consumer preferences. Apparently, the costs and benefits of these potential solutions, and how they will be financed, need to be evaluated. Real accounting marketing margins since 2001 showed that the farmer's share of the consumer's rand for the 48 fully certified organic EFO farmers rose, while their net returns (selling price less accounting costs) were lower than those of the pack-house agent and hawkers selling at the Isipingo market on the South Coast of KZN. Net returns for the 48 EFO farmers also seemed to be relatively higher if they sold through the informal supply chain (hawkers) rather than the formal supply chain. The EFO farmers' net returns may be improved by lowering operating costs and by aggressive marketing to customers willing and able to pay a price premium for organic crops. These farmers may also consider performing some of t he marketing services themselves (e.g. crop cleaning, grading and packaging) if they have the skills and can access more finance. There are, however, hidden benefits from maintaining the formal supply chain relationship, as the pack-house agent helped to secure tractor services and fencing, and facilitates access to the retailer. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2005.
