The Impact of Climate Change on Global Agriculture: Recent Evidence from Three Methodological Approaches

AAEA annual meeting track session

In the 2023 AAEA Annual Meeting track session (sponsored by the AAEA Land, Water and Environmental Economics section and the AAEA International Section) “The impact of climate change on global agriculture: recent evidence from three methodological approaches” authors discuss climate change significantly impacts crop growth and production, which may undermine the resilience of global food systems. Understanding the impact of climate change on global food production is, therefore, critical for ensuring global food security. The economic impacts of climate change on global agriculture have been extensively assessed over the past decades using CGE, IAM, and econometric methods. However, each of these methods have improved over time. This session will present the latest global results from each of these methods. For example, the number of crops considered has increased in the EPPA-Agriculture model, the GCAM model now explicitly captures the storage of agricultural outputs, and a new effort to synthesize the results of multiple Ricardian studies leads to new insights. The presentations will be followed by a discussion of the key takeaways from these three papers.

Presentations in this session:

  • Climate change effects on global agricultural markets: challenges to assess economic impacts and broad adaptation mechanisms
    Presented by: Angelo Gurgel
  • The critical role of agricultural storage and trade in moderating climate and biophysical shocks
    Presented by: Xin Zhao
  • The impact of climate change on global agriculture: evidence from the Ricardian literature
    Presented by: Allan Beltran

This session will take place on Tuesday, July 25 from 4:45 pm – 6:15 pm Eastern in the Marriott Marquis Washington DC in the Scarlet Oak room.
