The research assesses the economic and social impacts of climate change on the provision of ecosystem services relevant for food security in Mexico. Climate change causes an irreversible alteration in ecosystem services that directly and indirectly support economic activities of the food system. The research uses a CGE model that incorporates ecosystem services accounts of the SEEA (System of Environmental-Economic Accounting) to assess the trade-offs and synergies between ecosystem services and food value chains. Also, it evaluates the possible changes on household consumption and the effect of policy interventions. Therefore, the research focus on agriculture and on low-income households, which are the most affected by food insecurity.
