27 pages, With new possibilities offered by information and communications technology (ICT), an abundance of products, services, and projects has emerged with the promise of revitalizing agricultural extension in developing countries. However, a growing body of evidence suggests that not all ICT-enabled extension approaches are equally effective in improving adoption, productivity, income, or welfare outcomes. In this review, we explore various conceptual and methodological threads in the literature on ICT-enabled extension in developing countries. We examine the role of multiple impact pathways, highlighting how ICTs influence behaviors and preferences,gender and intrahousehold dynamics, spillovers, and public worker incentives. We also explore the opportunities presented by ICT-enabled extension for increasing the methodological rigor with which extension outcomes are identified. These conceptual and methodological insights—coupled with empirical evidence from prior studies—offer direction for several lines of policy-relevant research on ICT-enabled extension.
35 pages, We use data from a randomised experiment in Uganda to examine effects of incentives
on the decision to adopt drought-tolerant maize varieties (DTMVs) and mechanisms
through which effects occur. We find that social recognition (SR) incentives to a
random subset of trained farmers – disseminating farmers (DFs) – increase knowledge
transmission from DFs to their co-villagers and change information networks of both
DFs and their neighbours. SR also increases DFs’ likelihood of adopting DTMVs.
However, the corresponding results for private material rewards are not conclusively
strong. We find no evidence that incentives for knowledge diffusion increase the
likelihood of co-villagers adopting DTMVs
