Presentation by Ruth DeFries, CCAFS Science Workshop, Bonn, 10th June 2011

1. What strategies enhance or retard smallholders’ ability to adapt to climate variability? What factors are important? Which adaptation strategies (e.g. planting date, crop switch, alternative income) do or do not improve food security in different socioeconomic (e.g. income, credit) and biophysical (e.g. soils, climate, water) settings? What technologies (e.g. new cultivars, water management) are needed to make adaptation strategies work?

2. A coordinated multi-site study in CCAFS focus regions on adaptation strategies RESEARCH COMMUNITY Study design across gradient of biophysical and socioeconomic factors Field-based analysis of adaptation strategies Remote sensing to assess landscape-scale yields as function of strategies and other factors AGRICULTURE DEVELOPMENT COMMUNITY Identify relevant adaptation strategies Disseminate effective strategies Coordinate with technology development
