The document evaluates the uptake and impact of climate-smart agriculture (CSA) on food security, income, and assets in Nyando, Kenya, highlighting trends from 2011 to 2016. Significant improvements in food security, assets, and income were observed with the adoption of stress-tolerant crop varieties and improved livestock, while integrated soil and water conservation showed insignificant impacts. Recommendations include promoting CSA technologies, strengthening support services, and enhancing farmer collaboration.

- 1. Uptake and Impact of CSA on Food Security, Incomes and Assets in East Africa Case Study from Nyando in Kenya Maren Radeny, John Recha and Dawit Solomon
- 2. Introduction • Agricultural systems in EA are mainly rain-fed Highly vulnerable to climate variability and change Major climate-related risks: variable rainfall patterns, prolonged dry seasons, droughts, floods • CCAFS and partners have been working with communities in EA since 2011 Evaluate CSA technologies through the CSVs R4D approach - stress- tolerant crop varieties, improved small ruminants, integrated SWC • Objective - assess uptake and impact of CSA on HH food and nutrition security, income and assets Quasi-experimental approach - Statistical matching (PSM) and econometric modeling (ESR) to provide reliable estimates of impact
- 3. Results: Trends in uptake of CSA 0 20 40 60 80 100 2011 2012 2013 2014 2015 2016 Percentofhouseholds Year 0 20 40 60 80 100 2011 2012 2013 2014 2015 2016 Percentofhouseholds No resilient livestock breed introduced Introduced at least one resilient breed Fig 1. Uptake of improved crop varieties Fig 2. Uptake of improved livestock breeds • Increased uptake of CSA, including improved agronomic and livestock management practices • CSA adoption influenced by HH socio-economic and institutional factors
- 4. Results: Impacts of CSA • Multiple stress-tolerant crops – +significant impacts on all outcomes – food security (HDDS), assets and income • Improved small ruminants – +significant impacts on food security and assets; no effects on income • Integrated SWC – impacts insignificant • How can the CSA technologies be promoted for wider uptake, including feeding into policy processes • Need to strengthen other support services – climate information and agro-advisories, access to finance • Strengthening existing farmer experimentation networks & mobilizing farmers to work in groups
