Climate Change and Urban Development in Africa

Abstract

Climate change poses a major threat to sustainable urban development in Africa. Changes in the frequency, intensity, and duration of climate extremes (droughts, floods, and heat waves, among others) will affect the livelihoods of the urban population, particularly the poor and other vulnerable communities who live in slums and marginalized settlements. Extreme changes in weather patterns will increase incidences of natural disasters and impact on all key sectors of the economy, including the urban economy, agriculture and forestry, water resources, coastal areas and settlements, and health. In Africa, where livelihoods are mainly based on climate-dependent resources and environment, the effect of climate change will be disproportionate and severe. Moreover, Africa's capacity to adapt to and cope with the adverse effects of climate variability is generally weak. This Chapter examines the relations between climate change and urban development in Africa and looks at the role and effect of climate change on urban development. It also assesses the available policy options for adaptation and mitigating climate change effects in urban Africa.
