Climate change and water-related disasters will place increasing demands on urban systems and will result in increased migration to urban areas. The most vulnerable are the urban poor, since they often live in hazardous locations, such as flood plains, and in poor quality housing.

Water and urbanisation [ - 129 KB]
Half of humanity now lives in cities and, within two decades, nearly 60% of the world's population will be urban dwellers. Urban growth is most rapid in the developing world, where cities gain an average of 5 million residents every month. In Africa and Asia, the urban population will double between 2000 and 2030. Cities are growing because of: natural increase in urban population (50%), reclassification of rural areas as urban areas (25%) and rural-to-urban migration. The exploding urban population growth creates unprecedented challenges, among which provision for water and sanitation have been the most pressing and painfully felt when lacking.

In order to sustain both urban and rural livelihoods and ecosystems, there is a need for the sustainable management of the resources requirements of urban and peri-urban areas.
