The impact of droughts and floods on food security and policy options to alleviate negative effects
基于森的“权利方法”分析干旱和洪水如何导致农村生计的权利失败，并以马拉维为例说明政策干预（如补贴、公共工程、粮食储备管理）可缓解这些冲击。
Abstract This article introduces an analytical framework for understanding the impacts of droughts and floods on rural livelihoods, based on Sen's “entitlement approach,” and applies the framework to the recent food crises in Malawi. Weather shocks trigger a sequence of “entitlement failures,” which can result in a famine unless public action intervenes to mitigate these impacts. Policy responses can compensate for failures of production‐based entitlement (free or subsidized input distribution); labor‐based entitlement (public works programs or “employment‐based safety nets”); trade‐based entitlement (grain reserve management or food pricing policies); and transfer‐based entitlement (food aid or cash transfers).
