Global Urban Growth and the Geography of Water Availability, Quality, and Delivery

Globally, urban growth will add 1.5 billion people to cities by 2030, making the difficult task of urban water provisions even more challenging. In the article Global Urban Growth and the Geography of Water Availability, Quality, and Delivery, the authors develop a conceptual framework of urban water provision as composed of three axes: water availability, water quality, and water delivery. For each axis, quantitative proxy measures are calculated for all cities with more than 50,000 residents, and then the strategies cities are using in response if they are deficient on one of the axes are briefly discussed.
