ABSTRACT
In this chapter we discuss Challenge Program on Water and Food (CPWF) research on technologies and how it was used to define and research problems of water scarcity, water productivity, poverty, food security, livelihoods and the environment. We place technological research within the CPWF’s theory of change (ToC) and show how we used learning to inform engagement with decision-makers. We place learning in a longer-term, dynamic context taking account of previous and concurrent research.
