英文文献：Impacts Of Global Warming On Cropping Practices In Alberta
英文文献作者：Walburger, Allan M.,Klein, Kurt K.
英文文献摘要：
A Target MOTAD farm-level model was developed to assess the expected impacts from global warming on representative grain and oilseed farms in Alberta. It was found that a warmer climate would increase crop yields and length of the cropping season. Net returns and shadow values of land would increase substantially. Price risk generally was more important than yield risk under simulated warmer climates.
