Leveraging farmers’ social networks to improve co-production and dissemination of climate information services in SSA: a systematic review

Co-production of Climate Information Services (CIS) is increasingly recognized as vital for improving user engagement, local relevance and uptake in Sub-Saharan Africa (SSA). While empirical studies highlight the importance of social networks in CIS co-production, a comprehensive synthesis of how these networks improve co-production and dissemination to smallholder farmers is lacking. This paper synthesizes evidence across diverse SSA contexts to assess how farmers' social networks (FSNs) improve CIS co-production and dissemination. The findings show FSNs are central to CIS co-production and dissemination by integrating indigenous knowledge, improving contextual relevance and strengthening trust. These networks, comprising community leaders, peer farmers, kinship ties and farmer associations, bridge scientific and indigenous knowledge systems, facilitate collective interpretation of forecasts and enable rapid CIS dissemination. Enabling FSNs is key to effective CIS co-production and information exchange in SSA. Policymakers should strengthen FSNs through agricultural and rural development policies. Policy should institutionalize participatory co-production by integrating FSNs and indigenous knowledge systems into national CIS frameworks, supported by capacity building, blended financing and inclusive digital infrastructure. Future research should assess the relative effectiveness of formal and informal FSNs in facilitating CIS delivery and guide where to focus efforts on building stronger and more effective FSNs.
