The Impacts of Climate Change on African Cities

Chapter
Part of the Future City book series (FUCI, volume 4)

Abstract

Changes in the frequency and intensity of extreme events have significant impacts and are one of the most serious challenges faced by society in coping with a changing climate.

During the last ten years, floods have caused more damage than in the previous 30 years; for example, a flood event of 22 December 2011 in Dar es Salaam led to 20 deaths, considerable damage and loss of livelihoods. Moreover, higher temperatures have led to a high rate of evaporation and very dry conditions in some areas of the world. More generally, there is evidence of a global increase in the occurrence of severe weather events.

Africa is one of the most vulnerable continents to climate change and variability, a situation aggravated by a low adaptive capacity. Adaptation policies and actions will be most effective if based on the best knowledge concerning present and future climate.

This chapter aims to highlight and quantify the impact of climate change on the African cities Addis Ababa (Ethiopia), Dar es Salaam (Tanzania), Douala (Cameroon), Ouagadougou (Burkina Faso) and Saint Louis (Senegal), through the analysis of observed data and model projected changes in temperature and rainfall, synthesising the results of the CLUVA project (Climate Change and Urban Vulnerability in Africa). The climate projections were performed following emissions scenarios prepared by the Intergovernmental Panel on Climate Change’s Fourth and Fifth Assessment Reports, using a suite of global climate models and downscaling techniques.

The aim of the project is to evaluate the impact of climate change on the urban scale and, consequently, the possible works of adaptation. For this purpose, innovative downscaling techniques of climate projections were developed in order to achieve results at the urban scale.
