摘要: This paper presents a conceptual frameworkof the impact of climate change onagriculture. It assumes that climatechange will result in fertilizationeffect and shift agro-ecologicalconditions away from Equator towardsthe Poles. The agro-ecological islikely to reduce yield because reducedacreage fertilization effect willincrease yield. aggregate effectdepends on whichever two dominates. overall may beless significant than its distributionaleffects results are consistentwith previous empirical studies. Theimpact depends itspace. Faster changes willresult higher cost. assessment ofthe cost has consider is dynamic phenomenon mayrequire continuous adjustment. Environmental regulation emphasizesconservation increase ofadjustment environmental policiesshould emphasize adaptation andflexibility.
