Linkages Between Water Challenges and Land Use Planning in Megacities
Water Resources Impact
Defined by UN-HABITAT, a megacity is an urban area with over 10 million inhabitants. To date (2014), there are 28 megacities in the world. UN conservative growth projections predict that by 2030, there will be another 13 megacities in the world. In addition to the soon-to-be megacities, the world's projected future is filled with many other fast-growing cities in an increasingly urbanized world (Figure 1). Megacities' large population concentrations, locations on coasts or in drought-prone areas, and roles as national capitals and/or financial centers make their vulnerabilities to water-related disasters of widespread concern. The growing urban water needs of megacities pose significant social, environmental, and economic challenges for nations around the world.
