The U.S. Clean Power Plan’s impact on water has been largely overlooked, even though power plants account 45 percent of the country's water withdrawals.
Globally, changing water supply and demand is inevitable; what that change will look like is far from certain. A first-of-its-kind analysis sheds new light on the issue.
Decision-makers need future projections on water supply and demand. However, most of these decision-makers operate at the administrative or political scales, and therefore require country-level projections. This technical note utilized a spatial aggregation methodology to bring sub-catchment scale Aqueduct Water Stress Projections up to the country scale, fulfilling this need.
When it comes to water, most people don’t know what they’ve got ‘til it’s gone – yet we are already facing a water scarcity crisis.
Many of the world's biggest aquifers are being depleted much faster than they can be replenished, from the Middle East to India to California. New NASA satellite data reveals a looming global groundwater crisis.
Both private and public sectors see the need to plan for potential changes in water availability caused by climate change and economic development.
In certain areas of the world, more than 80 percent of the local water supply is withdrawn by businesses, farmers, residents and other consumers every year. These areas are particularly vulnerable to episodic drought.
Snow-capped mountain ranges no longer have snow. Citizens fear they'll lose access to water. And farmers continue to draw scarce groundwater.
So what can California do to shore up its dwindling water supply?
The availability of freshwater resources to meet human demands has emerged as a top-tier global issue for both environment and development. However, many decision-makers lack the technical expertise to fully understand hydrological information.
This working paper updates the 2013 Aqueduct Global Maps 2.0 Metadata Document. It describes the data sources and calculations for the Aqueduct Water Risk Atlas Global Maps. Complete guidelines and processes for data collection, calculations, and mapping techniques are described in the Aqueduct Global Maps 2.1: Constructing Decision-Relevant Global Water Risk Indicators.
Many places around the world have no idea how much groundwater and surface water they have, let alone how much they can use sustainably. The United Nation's proposed Sustainable Development Goals, however, could transform the way governments understand and manage scarce water resources.
Companies are realizing that managing water within their four walls is insufficient. Only coordinated, collective action can protect water resources and mitigate long-term business risks.
WRI evaluated the climate-water implications of more than 20 generation technologies in China, and found several win-win solutions for its power sector to reduce water impacts and emissions.
With the changing global climate, river flooding in cities worldwide has emerged as an immense challenge to urban resilience.
Since average global temperatures are already rising and the effects of climate change are becoming increasingly palpable around the world, cities need to focus on adaptation measures in order to strengthen their resiliency and better protect billions of global urbanites.
China’s power sector is its largest source of greenhouse gas emissions and also its biggest industrial water user. As a result, current and future decisions about electricity generation—and energy efficiency—will have profound impacts on both global climate and domestic water resources.
New analysis shows that approximately 21 million people worldwide could be affected by river floods on average each year, with that number rising to 54 million in 2030 due to climate change and socio-economic development.
In India, rapid industrialization and urbanization are taking place at a time when increases in water supply are limited.
As world leaders deal with climate change, aim to lift more people out of poverty, and make the world a more sustainable, prosperous place in 2015, here are the top Stories to Watch, according to WRI’s experts and as presented by WRI President and CEO Andrew Steer on January 8.
