“Rapid urbanization can hold long-term economic, social and environmental promise for developing countries if investments made now in infrastructure, housing and public services are efficient and sustainable, the World Bank says in a new report Planning, Connecting, and Financing Cities – Now: Priorities for City Leaders…In the next two decades, cities are expected to expand by another two billion residents, as people move in unprecedented numbers from rural areas to pursue hopes and aspirations in cities. More than 90 percent of this urban population growth is expected to occur in the developing world, where many cities are already struggling to provide basic needs such as water, electricity, transport, health services and education.”
