  1. The Effects of Climate Change on Agriculture Jamie Fletcher ECON331 March 29, 2010

  2. The Effects of Climate Change on Agriculture • Adaptation • International Trade • Impact on Developing vs. Industrial Countries

  3. Carbon Dioxide Emissions • Increased Global Temperatures • Increased Plant Fertilization

  4. CO2 Enrichment Richard S.J. Tol, “Estimates of the Damage Cost of Climate Change” (2001)

  5. Increased Global Temperatures and Crop Yields • Regional Variation • Colder Countries Benefit • Crop Yields Decrease in Temperate Areas • In Tropics, Agricultural Output Will Decrease

  6. Adaptation • Adaptation can mitigate the effects of climate change • Adaptation Capacity is Lower in Developing Countries

  7. Adaptation Richard S.J. Tol, “Estimates of the Damage Cost of Climate Change” (2001)

  8. International Trade • Bathtub Model for International Agricultural Markets

  9. SWOPSIM Model • A Partial Equilibrium Model That Is Used by Riley and Hohmann to Test The Sensitivity of Agriculture to Yield Losses in Major Grain Producing Regions

  10. Effects of International Trade • Interregional adjustments in production and consumption • Global Market Changes (Prices) • Impact of Developing Countries

  11. Conclusion • Adaptation • International Trade • Impact on Developing vs. Industrial Countries

  12. Sources • William R. Cline, Global Warming and Agriculture: Impact Estimates by Country (2007) • John Reilly and Neil Hohmann, “Climate Change and Agriculture The Role of International Trade” (1993) • Richard S.J. Tol, “Estimates of the Damage Cost of Climate Change” (2001)
