Ethiopia’s development potential is closely tied to seasonal rains, so high rainfall variation, together with lack of infrastructure, has undermined growth and perpetuated poverty. A single drought can cut growth potential by 10% over an extended period.
埃塞俄比亚和也门同样是典型的例证。埃塞俄比亚的发展潜力与季节性降雨密切相关，因此，极大的雨量变化和基础设施缺乏已经阻碍了发展，造成了持久的贫困。仅一次干旱就可能使发展能力在很长一段时期内降低10%。而也门没有可供常年使用的地表水，其公民用水完全依靠降雨、地下水和急流。
