Today, entering Trishal, Mymensingh on the road from Dhaka, one sees rows of fish ponds. One after the other, they show a massive diversification from rice to fish cultivation in recent years, and an intensification of production. The tradeoffs between green crops and silver fish appear to be clear, as ever more farmers see the benefits in terms of profits and returns, and make the move into fish farming.

“I have seen my income grow since I started farming frogs and fish” says Bounlium Planethavong, “but other farmers need support to adopt the techniques I use.” The CDAIS project identified this innovation that increases and diversifies household income and nutrition by promoting the production of aquatic protein sources.

Centred on a reservoir and irrigation scheme for livestock keepers and crop producers, the core objective of CDAIS Rwangingo catchment was to promote fair, effective and efficient use of water, as well asconflict management through collaboration among users. It stimulated a partnership framework among water users, service providers (including extensionists, input suppliers and water users organisations ) and supporters (Agri projects, enablers).

Cassava is an important crop especially in the south of Rwanda. A processing factory was constructed, but it was unable to source enough roots to make it profitable. Since CDAIS became involved, however, actors got together, saw the problems and agreed ways forward. Now a few years later business is booming for all involved, from farmers with a secure market, producers of improved planting material, and the factory itself that produces much more cassava flour and now employs 230 people.

In November 2016, a CDAIS capacity needs assessment of a community milk processing centre started a process that has seen clear changes in less than a year. The Burera dairy was selected as one of the country’s ‘innovation niche partnerships’, and the assessment, workshop and associated training allowed participants to better understand the value chain, the issues, problems, and possible solutions. Now, Burera dairy is moving forward, and quickly….

This document is designed to help researchers apply RCTs so they can gain a more accurate insight into the impacts of different extension strategies in different locations. It provides information on the benefits of an RCT approach in comparison to other impact evaluation models; provides a step-by-step implementation guide and a framework to avoid challenges; and demonstrates how an RCT approach was implemented within the context of the ‘Mind the Gap’ initiative.

This study analyse how agricultural extension can be made more effective in terms of increasing farmers’ adoption of pro-nutrition technologies, such as biofortified crops. In a randomised controlled trial with farmers in Kenya, the authors implemented several extension treatments and evaluated their effects on the adoption of beans biofortified with iron and zinc. Difference-in-difference estimates show that intensive agricultural training can increase technology adoption considerably.

There is an emerging body of literature analyzing how smallholder farmers in developing countries can benefit from modern supply chains. However, most of the available studies concentrate on export markets and fail to capture spillover effects that modern supply chains may have onlocal markets. Here, we analyze the case of sweet pepper in Thailand, which was initially introduced as a product innovation in modern supplychains, but which is now widely traded also in more traditional markets.

Agricultural innovations are seen as a key avenue to improve nutrition and health in smallholder farm households. But details of these agriculture-nutrition-health linkages are not yet well understood. While there is a broad literature on the adoption of agricultural technologies, most studies primarily focus on impacts in terms of productivity and income. Nutrition and health impacts have rarely been analyzed. In this article, we argue that future impact studies should include nutrition and health dimensions more explicitly.
