- 10 pages., Via online journal., Conservation Agriculture (CA) is a knowledge-intensive set of practices which requires substantial access to functional agricultural extension services to enable utilisation. Despite this importance, the perspectives of those providing extension services to smallholder farmers have not been fully investigated. To address this, we qualitatively explore the perspectives of agricultural extension providers across six African countries to understand why uptake of CA has been limited, as well as the institutional changes that may be required to facilitate greater utilisation. Across the diversity of geographical, political and institutional contexts between countries, we find multiple commonalities in the constrained utilisation of CA by smallholder farmers, highlighting the difficulties non-mechanised subsistence farmers face in transitioning to market-oriented farming systems such as CA. The primary constraint relates to the economic viability of market-oriented farming where farmers remain in low input and low output systems with limited exit points. The assumed exit point used by CA programs appears to have led to a culture of financial expectancy and reflects a continuation of top-down extension approaches with inadequate modification of CA to the contextual realities of subsistence farmers. If African agricultural systems are to be sustainably intensified, we find a need for greater flexibility within extension systems in the pursuit of sustainable intensification. If extension systems are to persist with CA, it will need to be promoted through more transitional pathways that disaggregate the CA package, and with that there is a need for the provision of a mandate to, and necessary funding for, more participatory extension services.

- Abstract via online journal. 2 pages., Technological innovation is vital to economic growth and food security in sub-Saharan Africa where agricultural productivity has been stagnant for a long time. Extension services and learning from peer farmers are two common approaches to facilitate the diffusion of new technologies, but little is known about their relative effectiveness. Selection bias, whereby well-motivated training participants would perform better even without extension services, as well as knowledge spillovers, where non-participants can indirectly benefit from extension services, are among the major threats to causal inference. Using a unique sequential randomized experiment on agricultural training, this study attempts to meet the dual objectives of executing rigorous impact evaluation of extension services and subsequent spillovers on rice production in Cote d’Ivoire. Specifically, to reduce selection bias, we randomly assigned eligibility for training participation; and to satisfy the stable unit treatment value assumption, control-group farmers were initially restricted from exchanging information with treated-group farmers who had received rice management training. Once some positive impacts were confirmed, information exchange between the treated and control farmers was encouraged. We found that the initial performance gaps created by the randomized assignment disappeared over time, due presumably to social learning from peer farmers. A detailed analysis concerning the information network and peer effects provided suggestive evidence that there were information and technology spillovers from treated to control farmers after removing the information exchange restriction. Overall, our study demonstrates that information dissemination by farmers can be as effective in improving practices as the initial training provided by extension services.
