Nearly half of the world’s population (47 per cent) lives in urban areas. The
accumulation of people, their consumption patterns, travel behaviour and their
urban economic activities have a large impact on the environment in terms of
resource consumption and waste discharges. However, cities also offer opportunities
to manage a growing population in a sustainable way. Increasing levels of
urbanization are caused by natural growth of the urban population and migration
of therural population towards cities. Cities play a major role not only as
providers of employment, shelter and services but also as centres of culture,
learning and technological development, portals to the rest of the world,
industrial centres for the processing of agricultural produce and manufacturing,
and places to generate income.
