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….

Connecting science with policy has always been challenging for both scientists and policy makers. In Ghana, Mali and Senegal, multi-stakeholder national science-policy dialogue platforms on climate-smart agriculture (CSA) were setup to use scientificevidence to create awareness of climate change impacts on agriculture andadvocate for the mainstreaming of climate change and CSA into agriculturaldevelopment plans.

This paper was synthesized from several scholarly literature and aimed at providing up-to-date information on climate change impacts, adaptation strategies, policies and institutional mechanisms that each agriculture subsector had put in place in dealing with climate change and its related issues in West Africa. For each subsector (crop, fishery and livestock), the current status, climate change impacts, mitigation and adaption strategies have been analyzed

Recently, a new approach to extension and climate information services, namely Participatory Integrated Climate Services for Agriculture (PICSA) has been developed. PICSA makes use of historical climate records, participatory decision-making tools and forecasts to help farmers identify and better plan livelihood options that are suited to local climate features and farmers’ own circumstances.
