Cities are considered to be at the frontline of the global climate change response, both from mitigation and adaptation perspectives. But many cities are engulfed in infrastructure deficits, carbon intensive development while urban poverty adds to this complexity in Africa. Africa's rapid urbanisation is coming with opportunities and challenges but the contribution of this urbanization to limit global warming at 1.5 degrees requires new knowledge on the interactions between adaptation and mitigation. Climate impacts on African cities are growing, with spatially differentiated warming of between 0.3 and 0.7 degrees. Rainfall redistribution and excessive rainstorms have impacted African cities in various ways. Many of the African cities are, however responding to the challenges through the formulation of adaptation plans, mitigation strategies with a strong focus on resilience and sustainable development — as outlined in the African Union's Agenda 2063. Given that most cities in Africa are low emitting cities, this paper discusses how adaptation and mitigation can be coupled using three scenarios in the context of 1.5-degree warming. It is also recognized that the different ecologies of Africa offer multiple possible pathways of adaptation and mitigation for increased African urban resilience.

1.5°C全球变暖下非洲城市的适应和缓解方案

从缓解和适应的角度来看,城市被认为是应对全球气候变化的第一线。但是,许多城市陷入了基础设施赤字,碳密集型发展的困境,而城市贫困加剧了非洲的这种复杂性。非洲的快速城市化带来机遇与挑战,但是这种城市化对将全球变暖限制在1.5度以内的贡献需要有关适应与缓解之间相互作用的新知识。气候对非洲城市的影响越来越大,不同地区的变暖幅度在0.3到0.7度之间。降雨的重新分配和暴雨过多以各种方式影响了非洲城市。但是,许多非洲城市正在通过制定适应计划来应对挑战,正如非洲联盟《 2063年议程》所概述的那样,减灾战略着重于抵御力和可持续发展。鉴于非洲大多数城市都是低排放城市,本文讨论了在1.5的背景下如何使用三种情景将适应和减缓结合起来度升温。人们还认识到,非洲的不同生态为增强非洲城市的适应能力提供了多种可能的适应和减缓途径。
