IDENTIFY pre-adapted varietiesto satisfy the needs of farmersand to find seeds that are likely to perform well in future climatesWHAT

WHYACCESSto better adapted varietiesreduced vulnerabilityincreased food securityto help farmers cope with the adverse effects of climate change on crop production

Lack of information and access to durumone of the major crops of Ethiopiaseeds of better-adapted varieties leaves many Ethiopian smallholder farmers vulnerable to increased food insecurity. The required diversity and traits, in the form of more than 3,000 durum wheat accessions, are available in the national gene bank held by the Institute of Biodiversity Conservation. Seeds for Needs is working to bridge the gap between farmers lack of access to seeds and the abundance of accessions in genebanks by providing locally-adapted seeds that are able to meet future conditions of unpredictable rainfall and changes in temperature.3

Climate change: divergent experiences and varied awareness, changes in rainfall most noticed.Fast economic change and growth: help motivate crop choices and varietal preferencesLimited crop diversity: CGB membership is a crucial factor in varietal choiceWheat rust is a key concern for farmers at the moment, offering a potential analogue for future climate change.
