The objective of this document is to develop a framework to analyze the nexus bioenergy and food security, namely to analyze the impact of possible national and subnational bioenergy developments in developing countries on food security. This analytical framework is to provide the best possible quality but also manageable information for national policy makers and other key stakeholders on the impacts of biomasS production for energy under different settings. This framework explicitly links existing analytical tools such as models or assessments that carry out specific analyses required to investigate the effects of bioenergy production on food security. As a starting point, this framework will be will be tested and demonstrated in three case study countries, i.e. Peru, Tanzania and Thailand. Through application and adaptation to these case study country contexts, the framework will be further refined The aim is to make the framework replicable in other countries.
