Social Capital, Resources Access and Vertical Coordination of Collective Actions in Value Chains: A Comparative Analysis Between Cote D’Ivoire and Ghana
Social capital plays a crucial role in collective action, yet its impact on farmers' access to resources, trust-based networks, and market coordination remains underexplored. This study examines how social capital shapes resource access and marketing strategies in farmer organizations, focusing on seven cases from the rice value chains in Côte d'Ivoire and Ghana. Using network analysis and Quadratic Assignment Procedure (QAP) correlation, the res…
Agricultural value chain transformations: A comparative analysis of milling segment upgrading in the rice value chains in Ghana and Ivory Coast
Do state-subsidized contractual arrangements improve farmers’ income? Empirical evidence from Algeria
To modernize agricultural value chains, some governments subsidize contract prices paid to farmers by private firms to encourage them to adopt contract farming. The impact of price-subsidized contracts on farmers’ incomes has not yet been evaluated. To help fill this gap, we evaluated the impact of a contractual arrangement with a subsidized sales price implemented by a tomato cannery in Algeria. Our results showed that the arrangement increased …
Unpacking policies for the development of agricultural growth poles in West Africa
This paper investigates public policies implemented in Burkina Faso, Côte d’Ivoire, Mali and Senegal to support the agricultural growth pole model. We critically assess assumptions regarding expected positive spillover effects through vertical coordination and tenure formalisation. Using a comparative analysis based on a typology informed by public economics, we show that policies centre on tax exemptions and land tenure, providing only limited s…
Contract Farming as a Last-resort Option to Finance Rice Cultivation in Senegal
We investigate the role of contracts in farmers’ access to credit over time using the conceptual framework of livelihoods and the economics of rural organisations. We applied multi-component analysis to a dataset of 594 rice farms in the Senegal river valley, analysed changes in 72 producer organisations’ funding strategies over time, and conducted 85 semi-directed interviews. Results show that individual farmers’ participation in contract farmin…
