Sustainable Urban Development

As cities continue to grow, the question of how to make urban areas environmentally sustainable, socially equitable, and economically viable has become one of the most pressing challenges of the twenty-first century. Sustainable urban development seeks to meet the needs of the present urban population without compromising the ability of future generations to meet their own needs — applying the Brundtland Commission (1987) definition of sustainable development to the urban context.

Key Definition: Sustainable urban development is development that improves the long-term social and ecological health of cities. It encompasses environmental protection, social equity, economic vitality, and effective governance, applied to the planning, design, and management of urban areas.
