Across four continents, teams of botanists, researchers, communicators, scientists and educators, have been working to research, collect, protect and utilise the wild relatives of our crop species in an effort to help adapt agriculture to climate change. The collecting effort described in this publication was part of a comprehensive, multi-year project that empowered national partners around the world to enrich their genebank collections. At the same time, this project has shared those resources with the global community under the rules of the International Treaty on Plant Genetic Resources for Food and Agriculture, to the ultimate benefit of farmers everywhere.
