  • New Map Documents Natural Resource Rights in Sub-Saharan Africa

    Many countries in Africa are rich with trees, wildlife, minerals, and other natural resources. But as new WRI research and an interactive map show, few national laws provide communities with strong, secure rights to the resources on their land.

    WRI conducted a systematic review of the national framework laws for five natural resources—water, trees, wildlife, minerals, and petroleum—in 49 sub-Saharan African countries. The results are presented in our new Rights to Resources map.

  • A New Strategy to Improve Water Quality—One Targeted Watershed at a Time

    Few programs have seen widespread success in tackling water quality problems in the Mississippi River Basin and Gulf of Mexico, but an emerging initiative could present a way forward. The U.S. Department of Agriculture (USDA) launched the Mississippi River Basin Healthy Watersheds Initiative (MRBI) in 2009. New WRI research finds that with some specific improvements, the MRBI’s new approach could play a key role in improving the nation’s inland and coastal water quality.

  • India’s Watershed Development Boosts Food Security, Improves Livelihoods

    India struggles with water scarcity, a problem that poses especially huge implications for the country’s food security and rural livelihoods. The country has long-battled its scarcity issues through Watershed Development, a participatory approach to improve water management through afforestation and reforestation, sustainable land management, soil and water conservation, water-harvesting infrastructure, and social interventions. But while watershed development has been employed in communities throughout India, its potential long-term costs and benefits have not been well-understood or studied--until now.

    A new working paper from WRI and WOTR finds that watershed development has provided more than $9 million dollars’ worth of food security and water management benefits to the water-stressed community, Kumbharwadi.

  • World’s 36 Most Water-Stressed Countries

    WRI’s Aqueduct project recently evaluated, mapped, and scored water risks like these in 100 river basins, ranked by area and population, and 180 nations—the first such country-level water assessment of its kind. We found that 36 countries face “extremely high” levels of baseline water stress (see list at bottom). This means that more than 80 percent of the water available to agricultural, domestic, and industrial users is withdrawn annually—leaving businesses, farms, and communities vulnerable to scarcity.

  • Water Risks on the Rise for Three Global Energy Production Hot Spots

    Energy and consulting firm Wood Mackenzie, supported by data and analysis from WRI’s Aqueduct Water Risk Atlas, surveyed water risks among the world’s top energy-producing regions. They found that three energy sectors face particularly high water risks: shale gas in the United States, coal production and coal-fired power in China, and crude oil in the Middle East.

  • One-Quarter of World’s Agriculture Grows in Highly Water-Stressed Areas

    A new interactive map from WRI’s Aqueduct project reveals that more than 25 percent of the world’s agriculture is grown in areas of high water stress. This figure doubles when looking at irrigated cropland, which produces 40 percent of global food supply.

    This analysis highlights the tension between water availability and agricultural production. Finding a balance between these two critical resources will be essential—especially as the global population expands.

  • China’s Response to Air Pollution Poses Threat to Water

    Record-setting levels of smog this week shut down Harbin, a city of 11 million people in northeast China. Officials blamed increased coal consumption during the first days of winter heating, underscoring the urgency of the China State Council’s recently announced initiative to address persistent smog in major cities.

    But while the Air Pollution Control Action Plan has ambitious goals—cutting air particulates and coal consumption—it may create unintended problems for the country’s water supply.

  • Need Clean Water? Invest in Nature

    Securing clean water is becoming increasingly difficult in the United States. Infrastructure like dams and treatment plants are aging, water demand is increasing, and more frequent extreme weather events like wildfires and flooding are driving up the cost of water management.

    It’s a complex problem, but one of the potential solutions is decidedly low-tech: Invest in nature.

  • Conflicting Reporting Systems May Hinder Companies' Water Risk Strategies

    Water risks such as floods, scarcity and pollution are increasingly chipping into corporate bottom lines. The financial sector is taking notice--and taking action.

    Calvert Investments asked Hanes Brands to evaluate its losses from cotton-supply shortages due to the 2011 US drought, determining that the company lost $5.2 billion.

  • Water Risk on the Rise

    This article first appeared in Project Syndicate

    Water is never far from the news these days. This summer, northern India experienced one of its heaviest monsoon seasons in 80 years, leaving more than 800 people dead and forcing another 100,000 from their homes. Meanwhile, Central Europe faced its worst flooding in decades after heavy rains swelled major rivers like the Elbe and the Danube. In the United States, nearly half the country continues to suffer from drought, while heavy rainfall has broken records in the Northeast, devastated crops in the South, and now is inundating Colorado.

    Businesses are starting to wake up to the mounting risks that water – whether in overabundance or scarcity – can pose to their operations and bottom line. At the World Economic Forum in Davos this year, experts named water risk as one of the top four risks facing business in the twenty-first century. Similarly, 53% of companies surveyed by the Carbon Disclosure Project reported that water risks are already taking a toll, owing to property damage, higher prices, poor water quality, business interruptions, and supply-chain disruptions.

    The costs are mounting. Deutsche Bank Securities estimates that the recent US drought, which affected nearly two-thirds of the country’s lower 48 states, will reduce GDP growth by approximately one percentage point. Climate change, population growth, and other factors are driving up the risks. Twenty percent of global GDP already is produced in water-scarce areas. According to the International Food Policy Research Institute (IFPRI), in the absence of more sustainable water management, the share could rise to 45% by 2050, placing a significant portion of global economic output at risk.
