In August 2012 LCIRAH and the University of Aberdeen were commissioned by UK Department for International Development (DFID) to complete a study on ‘Current and planned research on agriculture for improved nutrition: a mapping and a gap analysis’. The resulting report examines current and future research projects on agriculture for improved nutrition and uses a mapping process to identify gaps in research coverage. A conceptual framework has been developed to define and characterise agricultural research for improved nutrition. Placing nutrition at the centre, the framework identifies pathways by which innovations in agriculture research may contribute directly and indirectly to nutrition and how we should measure their success. Evidence of impact may be gathered along these. The report draws a roadmap for policy-makers and recognises the pivotal role of knowledge and evidence in nutrition policies and programmes.
