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

INTERNATIONAL TRADE
• Bathtub Model for International Agricultural Markets

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

EFFECTS OF INTERNATIONAL TRADE
• Interregional adjustments in production and consumption
• Global Market Changes (Prices)
• Impact of Developing Countries

• International Trade
• Impact on Developing vs. Industrial Countries
