Towaoc Had No Running Water in the 1970s. Now it Does, and the Tribe Irrigates a Farm. What Changed?

Israel has grappled with crippling drought for years. But people have learned to use Mediterranean sea water and recycled wastewater to provide the country with enough water for all its needs.

After the drought hit Australia in the early 2000s, city officials had to start thinking seriously about ways to conserve and creatively store their water. External tanks became the solution, storing rain runoff to create an available source of water for Melbourne residents. This solution may not fit every location, but there are other teachable lessons such as taking radically shorter showers.

Laws in Texas and New Mexico, both locked in the grip of a crippling drought, don't do much to actually encourage citizens to conserve water. New conservation laws and financial incentives are trying to change that.

For the past three years, water levels in the San Antonio Edwards Aquifer have decreased to uncomfortable levels and drought periods may continue as the population booms. The San Antonio Water System organization has set up rules to limit water use and has recycled water for conservation frugal innovation.

In just the next couple of decades, the World Bank says, farmers across Africa could lose more than half their cropland to drought and heat - the issue is considered so pressing that, a few years ago, Malawi's Department of Meteorological Services added "Climate Change" to its name. A new aid group group now works with farmers in more than 60 villages — with plans to expand — helping them become more resilient to a changing climate.

Farmers in California increasingly face water shortages. To help solve the problem, some are looking to Australia, where a national water market has provided an economic solution. By buying and selling water rights, farmers have incentives to reduce consumption.

The U.S. government has developed different sensors for irrigation devices that gauge water demand and help conserve use. as water shortages caused by drought have increased across the globe, and farmers are faced with economic burdens, such technology is focusin on sustainability for the future.

In a country of limited resources — and perhaps for that very reason — preparing for natural disasters is top of the agenda in Bangladesh. Various grassroots, collaborative programs have been put in place over the years to help address many facets of the calamities caused by cyclones, from improved emergency shelters to long-term support for those who lose their livelihoods in the storms.

Clean water and healthy ecosystems are becoming increasingly difficult to come by. With floating islands and other inventions, eco-entrepreneur Bruce Kania thinks that biomimicry - such as reconstructing wetlands and growing biofilms - can tackle the toughest of water problems.

Warming water has led to the collapse of coral reef systems in the western Indian Ocean, essential to fisheries, protecting shorelines, and reducing beach erosion and sea-level rise. Marine scientists from Nature Seychelles, as part of an international project to protect and restore the reefs, are promoting varieties of coral that they have found to be resistant to the rise in temperature.
