In certain areas of the world, more than 80 percent of the local water supply is withdrawn by businesses, farmers, residents and other consumers every year.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?
Constructing Decision-Relevant Global Water Risk Indicators
This working paper explains the methodology used to generate the hydrological metrics and indicators in the Aqueduct Water Risk Atlas. For a detailed list of data sources, see the Aqueduct Global Maps 2.1 Metadata Document.
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.
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.
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.
India is one of the most water-challenged countries in the world, from its deepest aquifers to its largest rivers.
The India Water Tool 2.0 is the most comprehensive, publicly available online tool evaluating India’s water risks.
This technical note describes the specifics of the indicator data and calculations underpinning the India Water Tool 2.0 (IWT).
The IWT 2.0 allows companies, government agencies, and other users identify their water risks, prioritize their water management actions, plan for sustainable...
