The future adequacy of freshwater resources is difficult to assess, owing to a complex and rapidly changing geography of water supply and use. Numerical experiments combining climate model outputs, water budgets, and socioeconomic information along digitized river networks demonstrate that (i) a large proportion of the world's population is currently experiencing water stress and (ii) rising water demands greatly outweigh greenhouse warming in defining the state of global water systems to 2025… 

Vulnerability of Korean water resources to climate change and population growth.

While freshwater is more vulnerable to growth scenarios than the climate change scenario, climate change alone could decrease mean annual runoff by 10% in four major river basins by 2030.

Statistical Analysis to Detect Climate Change and Its Implications on Water Resources

Climate change has affected diverse physical and biological systems worldwide. The impact of climate change on water resources is one of the most important. Even though the world’s water resources

What about reservoirs? Questioning anthropogenic and climatic interferences on water availability

Water resources in semi‐arid regions like the Mediterranean Basin are highly vulnerable because of the high variability of weather systems. Additionally, climate change is altering the timing and

Integrated, watershed-based management for sustainable water resources

Water scarcity is a becoming a critical issue globally, driven largely by the demands of an exponentially growing human population and complicated by the impacts of climate change on the amounts and

Assessing the Impact of Climate Change on Water Resources: The Challenge Posed by a Multitude of Options

Global warming due to anthropogenic emissions of greenhouse gases is already altering the Earth’s climate. A changing climate implies shifts in long-term temperature and precipitation patterns, which



Future availability of water in Egypt: the interaction of global, regional, and basin scale driving forces in the Nile Basin

This paper describes the impacts on the future availability of water in Egypt of driving forces operating at three different scales in the Nile Basin: global (climate change), regional (land-use

The World’s Water: The Biennial Report on Freshwater Resources

Produced biennially, "The World's Water" is the most comprehensive and up-to-date source of information and analysis on freshwater resources. Each new volume examines critical global trends and

Human Appropriation of Renewable Fresh Water

Humanity now uses 26 percent of total terrestrial evapotranspiration and 54 percent of runoff that is geographically and temporally accessible. Increased use of evapotranspiration will confer minimal

Global system of rivers: Its role in organizing continental land mass and defining land‐to‐ocean linkages

The spatial organization of the Earth's land mass is analyzed using a simulated topological network (STN‐30p) representing potential flow pathways across the entire nonglacierized surface of the

A digital global map of irrigated areas.

For the purpose of global modeling of water use and crop production, a digital global map of irrigated areas was developed. The map depicts the percentage of each 0.5° by 0.5° cell that was equipped

ABSTRACT This paper contains the text of the Chow Memorial Lecture, delivered at the VIIth World Congress on Water Resources Rabat, Morocco, May 13–18, 1991. The paper addresses water-cycle related

Relation between satellite observed visible-near infrared emissions, population, economic activity and electric power consumption

The area lit by anthropogenic visible-near infrared emissions (i.e., lights) has been estimated for 21 countries using night-time data from the Defense Meteorological Satellite Program (DMSP)
