Résumé : In Colombia and Ecuador, climate change is impacting agricultural systems which may end up being abandoned under the combined effects of extreme climate events, agricultural sanitary crises, and economic shocks. To address these risks, adequate climate information enables farmers to adapt their practices to expected climate conditions. However, the climate information disseminated for this purpose is often top-down and poorly adapted to the needs of farmers, who are not sufficiently involved in the process for its provision. To address this issue, this thesis explores the conditions for sustainable and robust collective action for the coproduction of actionable climate information for farmers in Colombia and Ecuador. To this end, we propose an analytical framework combining the Institutional Analysis and Development (IAD) and the Social-Ecological Systems framework (SES) of Elinor Ostrom and the Bloomington School, which we apply to several field studies carried out using ethnographic methods in both countries. By analyzing situations ranging from the production of data by networks of meteorological stations to the creation of agroclimatic information in Colombian Technical Agroclimatic Committees, we show the diversity of collective action problems at the different stages of climate information provision. Based on these empirical case studies, we show polycentric systems’ potential to coordinate the efforts for climate change adaptation at various scales, but also their limitations in a context with strong power imbalances. We thus demonstrate how the institutional design of climate services plays a part in agricultural systems governance through feedback effects between agricultural social-ecological systems and climate services. While fruitful collaborations between public and private actors are possible, we stress the importance of rules that ensure the equitable support of farmers and avoid reinforcing the marginalization of underprivileged populations. Through this interdisciplinary work, we open new perspectives on the conditions under which policymakers can support climate change adaptation through just and equitable systems.
