Why a 4-Degrees World Won't Cause Just One Water Crisis

There is much talk of a water crisis. We who work in water don't really see just one; we see lots of different water crises already now, getting worse as we move towards 2 and eventually 4 degrees above pre-industrial temperatures. Floods in some places, droughts in others, poor operation and maintenance making infrastructure unable to protect citizens in some places, lack of enforcement of rules leading to pollution crises or rampant overuse of groundwater in many others. So there are lots of water crises, some caused by nature, some by humans and most some a combination of the two.

Generating Marine Electricity: Transitioning From Subsidies to Commercial Financing

Alexander McPhail's picture
In-stream tidal units convert the energy of tides and currents into power – a type of hydropower which has operated successfully for decades. No matter what you call it -- wave, in-stream tidal, river current, or hydro turbines; or where it sits -- sitting on the river bottom or suspended from a barge -- the technology has proven itself. What has remained more elusive is the much-needed transition from subsidies to commercial financing.

International Day for Biological Diversity: Biodiversity Can Provide the Basis for Effective Water Management

Charles J. Vorosmarty's picture
This year International Day for Biodiversity (May 22) is focused on “Water and Biodiversity” to coincide with the United Nations declaration of 2013 as the International Year for Water Cooperation. Effective water management has traditionally been viewed as an important factor in maintaining biodiversity in ecosystems. The opposite is increasingly viewed as critical: biodiversity can provide the basis for effective water management.

International Day for Biological Diversity: The Water Value of Forests

To increase awareness and understanding about the many ways forests contribute to improving food security and nutrition, especially in developing countries, the FAO hosted an International Conference on Forests for Food Security and Nutrition (May 13-15) in collaboration with the World Bank and with

Stepping Up Efforts to Address Water Issues

Diego Juan Rodriguez's picture
As recognized by the World Economic Forum at Davos earlier this year, water insecurity is one of the greatest risks facing the world today.  Increased water demand from growing populations and economies, combined with more uncertainty in supply due to expected climate change impacts, require a radical change in the priority we give to managing our water resources and systems to supply water to people.  Over the next two decades, water will be needed to feed a planet of 9 billion people and generate energy to meet increased demand.

Cutting Water Consumption in Concentrated Solar Power Plants

Julia Bucknall's picture
Concentrated solar power (CSP) systems are a great promise for renewable energy at scale.  But they can use a lot of water, which is a problem since they tend to be located in places where water is scarce. Some concentrated solar technologies need to withdraw as much as 3,500 liters per Megawatt hour (MWh) generated.

The U.S. Drought Monitor: A Sophisticated Tool, But Do Not Be Intimidated by It

Nate Engle's picture

Evaluating the existence and extent of droughts is not an easy task. Not only are droughts "slow-onset" events that creep into the physical, environmental, and social systems of a region, they also have effects that span numerous sectors of a society. The U.S. Drought Monitor (USDM), as recently described by Dr. Michael Hayes from the National Drought Mitigation Center (NDMC) during a recent presentation at the World Bank, provides an example for other nations as they consider how to effectively manage this difficult endeavor of characterizing drought risks and impacts.

Septage : Kerala’s Looming Sanitation Challenge

Suseel Samuel's picture

Kerala is a beautiful state in South India, home to about 34 million people, many of whom share my pride as a Keralite.  Of all the states in India, Kerala scores the highest on the  human development index, has one of the highest literacy rates in India (around 95%), a low Infant Mortality Rate,  gender ratio in favor of the female population, stunning landscapes (highlands, mid-lands, low-lands), and a booming tourism industry. It is God’s own country, as the promoters of tourism industry has named it.
