Global Environmental Change and Food Systems (GECAFS) was launched in 2001 as a 10-year, comprehensive programme of international, interdisciplinary research focused on understanding the links between food security and global environmental change. GECAFS will improve understanding of the relationship between food systems and the Earth System to deliver science-based tools for analysing the socioeconomic and environmental consequences of adaptation strategies. These will be designed to help policy-makers and managers evaluate the best options for reducing vulnerability of food systems to global environmental change while minimising further environmental degradation.
To determine strategies to cope with the impacts of global environmental change on food systems and to assess the environmental and socio-economic consequences of adaptive responses aimed at improving food security.
This goal will be achieved by improving understanding of the interactions between food systems and the Earth System's key socioeconomic and biogeophysical components. The research agenda is specifically targeted towards delivering the new science necessary to underpin policy formulation for improving food security in the face of global environmental change.
GECAFS is delivering a number of science-based products to help achieve the long-term aims, for example:
