  • WFP uses new tech to fight refugee food shortages in Jordan

    Jordan is dealing with an influx of Syrian refugees that are putting a strain on already scarce resources like water. In response, the United Nations World Food Program has started to grow barley and other foods hydroponically in a process that uses 90% less water than traditional methods. Beyond the innovations in the lab, new technology is also allowing refugees to shop freely in local supermarkets and use their irises—checked with eye scans—to pay for their groceries from their given funds. This eliminates the threat of theft and is improving food access across Jordan.

  • Desertification Is Devouring India. But There's Hope in the Dunes

    The people of a small village on the edge of the Thar Desert have managed for decades to resist "desertification" -- degradation of arid land to the point that it is uninhabitable -- by storing monsoon waters for use later. The storage device, rectangular plots of land called chaukas, have worked well enough to be copied by dozens of other villages in the area. It is uncertain if this approach can reverse the loss of land, but it is at least holding off the rapid pace of desertification, which risks mass displacements of people as hundreds of millions of acreage is lost.

  • Water from air: ASU professor's technology produces clean drinking water around the globe

    An elementary school program is teaching students about renewable energy in action. By working with the startup Zero Mass Water, educators can share lessons from the company’s hydropanels, which use solar energy to capture water from the air and turn it into drinking water. The technology is now being used worldwide.

  • Coastal Recovery: Bringing a Damaged Wetland Back to Life

    A coastal recovery project in Delaware Bay is using a technique that they call "engineering with nature" to bring back the 4,000 acres of wetlands from the disastrous effects of human interference and climate change. They use a multitude of strategies, such as stabilizing the dunes and replanting native grasses, and although they approach the project as a research study without progress yet, they have already begun to see a return of wildlife including birds, eels, and crabs. Similar efforts to restore wetlands are also taking off across the globe.

  • pH7

    After the legacy of acid mine drainage from abandoned coal mines in Appalachian Ohio, there are several initiatives working to clean up the rivers and streams. Change-agents from universities, local organizations, and the government joined together in the 1990s to use both active and passive methods of neutralizing the pH level of the streams. Since then, they've brought the pH acidity down from 4.5 to 7 and grown the number of fish species from 4 to 37, and efforts are still ongoing and optimistic.

  • Could Hawaii Be Paradise For Hydrogen-Powered Public Transit?

    Funded by federal grant money, the state, and the Office of Naval Research, Hawaii County public transit has developed its first hydrogen-powered shuttle bus. What’s been called the “fuel of the future,” hydrogen fuel cells create a power source that’s only emissions are clean water vapor. While a seemingly viable and scalable clean-energy source, such development and infrastructure requires large financial investments that many states have yet to prioritize.

  • New Mexicans Use Rain Gauges to Help Scientists Map Precipitation Levels

    When it comes to meteorology, citizen science can be a powerful resource. In New Mexico and neighboring states, volunteers are collecting data that helps researchers and state agencies map rainfall patterns. Through CoCoRaHS, an online network, that information is reaching diverse stakeholders, from farmers to insurers.

  • Western Water Managers Bet On Cloud Seeding, Despite Gaps In Science

    In the American Southwest, state water managers have been investing for decades in weather modification programs, otherwise known as "cloud seeding." Colorado River Basin states recently agreed to expand that effort, hoping to build crucial snowpack. But some scientists are skeptical that cloud seeding can produce reliable supplies, citing huge data gaps.

  • Climate Change, the Rio Grande and Border Water

    The Rio Grande River, which provides water to 6 million people and irrigates 2 million acres of farmland, is one of many transnational sources of water imperiled by climate change. Indeed, many states and countries that share water are drawn into conflict over dwindling resources. One relationship between officials in Mexico and the U.S. offers some hope that (with the right coaching) countries can cooperate, even in the face of greater political problems.

  • Can the Great Lakes continue to fend off an increasingly thirsty world?

    The Great Lakes contain 84 percent of the surface freshwater in North America—a staggering 21 percent of the surface freshwater worldwide. To manage the resource sustainably, all eight lake-bordering states, Congress, and Canadian provinces created the Great Lakes Compact in 2008, which has regulated and curbed water use. An evaluation of the agreement ten years later shows promising yet mixed results. And critically, it asks whether strong policies can withstand a future of growing water scarcity.
