Achieving food security in the face of climate change is a major challenge for humanity in the 21st century. However, comprehensive analyses of climate change impacts, including global market feedbacks, are still lacking.
Focusing on four Eastern Asian countries - China, Japan, South Korea and Mongolia - and using a global integrated modeling framework, ESM researchers showed that:
Researchers then investigated how pressure on the food system in Eastern Asia could be mitigated by a consumer support policy. It was found that the costs of adaptation policies to 2050 varied greatly across climate projections. The costs of consumer support policies would also be lower if only implemented in one region. However, market price leakage could exacerbate pressure on food systems in other regions.
Scientists conclude that climate adaptation should no longer be viewed only as a local geographically isolated problem.
