Urbanisation and the environment

Project

Growing urban affluence tends to have profound environmental consequences, but the net impact depends heavily on how the transition is managed. IIED is working to identify the best means of making urbanisation more environmentally beneficial and less destructive.

It is hard to say whether urbanisation is environmentally beneficial or destructive. As our past work on urban environmental transitions has shown, it is growing urban affluence driven by economic growth that tends to have the more profound environmental consequences, shifting the predominant burdens from local health concerns (such as bad households sanitation and indoor air pollution), towards city and regional problems (such as pollution of the waterways and the ambient air) and towards threats to global sustainability (through high consumption patterns and carbon emissions).

At every scale, however, measures undertaken in urban areas can reduce the burdens, and we have worked with the United Nations Environment Programme (UNEP) to examine how environmental improvement can be integrated into urban planning and management (PDF).

We have also worked to highlight environmental concerns, such as those summarised in a Working paper on urban groundwater, which is critical to large numbers of mostly low-income households using wells in urban Africa and Asia.

Issues of urbanisation and environment are also closely linked to our cities and climate change work, including that summarised in books published with the United Nations Population Fund (UNFPA) on 'Population dynamics and climate change' and 'The demography of adaptation to climate change'.
