How Can African Agriculture Adapt to Climate Change? A Counterfactual Analysis from Ethiopia
研究分析了埃塞俄比亚尼罗河流域不同适应策略对作物净收入的影响，发现组合策略（如改变作物品种结合水土保持）能显著提高收入，而单一策略效果有限。
We analyze the impact of different adaptation strategies on crop net revenues in the Nile Basin of Ethiopia. We estimate a multinomial endogenous switching regression model of climate change adaptation and crop net revenues and implement a counterfactual analysis. Households data are combined with spatial climate data. We find that adaptation to climate change based upon a portfolio of strategies significantly increases farm net revenues. Changing crop varieties has a positive and significant impact on net revenues when coupled with water conservation strategies or soil conservation strategies, but not when implemented in isolation. <i></i>
