Nearly 3 billion additional urban dwellers are forecasted by 2050, an unprecedented wave of urban growth. While cities struggle to provide water to these new residents, they will also face equally unprecedented hydrologic changes due to global climate change. Here we use a detailed hydrologic model, demographic projections, and climate change scenarios to estimate per-capita water availability for major cities in the developing world, where urban growth is the fastest. We estimate the amount of…

Future global urban water scarcity and potential solutions
The global urban population facing water scarcity is projected to increase from 933 million in 2016 to 1.693-2.373 billion people in 2050, with India projected to be most severely affected in terms of growth in water-scarce urban population.
Global Urban Growth and the Geography of Water Availability, Quality, and Delivery
This article develops a conceptual framework of urban water provision as composed of three axes: water availability, water quality, and water delivery, and discusses the strategies cities are using in response if they are deficient on one of the axes.
Impacts of urbanization on stream water quantity and quality in the United States
Since the 1950s, the world’s urban population has grown more than 400% to 3.9 billion today. About 60% of the total population is expected to live in urban areas by the year 2025. For the United
Effects of Urban Development Patterns on Municipal Water Shortage
While urban areas are being threatened by water shortage due to climate change and rapid population growth, effects of urban development patterns on future municipal water shortage are rarely
Urbanization Forecasts, Effects on Land Use, Biodiversity, and Ecosystem Services
Several studies in recent years have forecasted global urban expansion and examined its potential impacts on biodiversity and ecosystem services. The amount of urban land near protected areas (PAs)
Optimizing Urban Infrastructure Resilience Under Precipitation and Population Growth Uncertainties
Increased urbanization, infrastructure degradation, and climate change threaten to overwhelm stromwater systems across the nation, rendering them ineffective. Green Infrastructure (GI) practices are
Projecting global urban land expansion and heat island intensification through 2050
Urban populations are expected to increase by 2–3 billion by 2050, but we have limited understanding of how future global urban expansion will affect urban heat island (UHI) and hence change the
Water Quantity and Quality at the Urban–Rural Interface
Population growth and urban development dramatically alter natural watershed ecosystem structure and functions and stress water resources. We review studies on the impacts of urbanization on

Long-range water facility planning must consider global climate change in the recommended mix of new facilities needed to meet future water requirements, and planning for future water needs should include explicit consideration of the potential range of global warming impacts.
The rising tide: assessing the risks of climate change and human settlements in low elevation coastal zones
Settlements in coastal lowlands are especially vulnerable to risks resulting from climate change, yet these lowlands are densely settled and growing rapidly. In this paper, we undertake the first
Water transfers, agriculture, and groundwater management: a dynamic economic analysis.
Continental scale models of water balance and fluvial transport: An application to South America
A coupled water balance and water transport model (WBM / WTM) was constructed as part of a larger study of global biogeochemistry. The WBM / WTM provides critical hydrologic information to models of
Global irrigation water demand: Variability and uncertainties arising from agricultural and climate data sets
Agricultural water use accounts for around 70% of the total water that is withdrawn from surface water and groundwater. We use a new, gridded, global‐scale water balance model to estimate interannual
Cities vs. agriculture: A review of intersectoral water re‐allocation
Water demand management, or making better use of the water we have — as opposed to augmenting supply — is increasingly proposed as a way of mitigating water-scarcity problems. Moving water away from
Millennium Ecosystem Assessment scenario drivers (1970–2050): Climate and hydrological alterations
This study was carried out to support and enhance a series of global studies assessing contemporary and future changes in nutrient export from watersheds (Global Nutrient Export from Watersheds
