Global Report on Human Settlements 2009: Planning Sustainable Cities 全球人类住区报告2009：规划可持续的城市

Current urban planning systems are not equipped to deal with the major urban challenges of the 21st century, including effects of climate change, resource depletion and economic instability, plus continued rapid urbanization with its negative consequences such as poverty, slums and urban informality. These planning systems have also, to a large extent, failed to meaningfully involve and accommodate the ways of life of communities and other stakeholders in the planning of urban areas, thus contributing to the problems of spatial marginalization and exclusion. It is clear that urban planning needs to be reconsidered and revitalized for a sustainable urban future. Planning Sustainable Cities reviews the major challenges currently facing cities and towns all over the world, the emergence and spread of modern urban planning and the effectiveness of current approaches. More importantly, it identifies innovative urban planning approaches and practices that are more responsive to current and future challenges of urbanization.
