Measuring impacts and adaptations to climate change: a structural Ricardian model of African livestock management1
提出一种新的横截面方法，将适应行为纳入气候变化影响分析，研究非洲农民如何通过改变牲畜种类和数量来适应气候，发现温暖地区农民从肉牛转向更耐热的山羊和绵羊，湿润地区则转向山羊和鸡。
Abstract This article develops a new cross‐sectional methodology that explicitly incorporates adaptation into an analysis of the impacts of climate change. The methodology examines how a farmer will change choices of species and number to adapt to climate. The approach is applied to study Africa, where the impacts of climate change are expected to be the most severe. The results indicate that in warmer places, African farmers switch from beef cattle to more heat‐tolerant goats and sheep. In wetter places, farmers switch from cattle and sheep to goats and chickens. The results indicate that large commercial livestock operations specializing in beef cattle will be hard hit from climate change whereas small farmers who can easily substitute to goats and/or sheep will be more resilient.
