"Cinq minutes pour se laver, c'est suffisant" : au camping d'Arradon, les douches sont chronométrées pour économiser l'eau

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.

While some parts of the United States struggle with drought, others are faced with more water than they know what to do with. Minnesota reconstructs roads and drainage systems in order to be more prepared for the large amounts of rain fall they have received, largely due to climate change.

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.

Although Nigeria "is arguably the worst-run of the world’s major countries," it's biggest city is providing a model for how to turn poor governance around. Lagos, a historically fragile city like the rest of Nigeria, has devolved more power to civilian rule, which has shown positive results for the health of the city.

Geography and climate change challenge the viability of sea-level cities in Vietnam, but architects, researchers, and urban planners work together to find creative solutions. One architect in Ho Chi Minh City designed green roofs to absorb the rainwater that causes floods.

While critics argue that Naloxone isn't safe for over-the-counter use, some cities have found success distributing Naloxone to community members to help save lives of addicts who overdose. Naloxone can be administered to help those overdosing survive and jump-start the withdrawal process.

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.

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.

South Dakota’s “24/7 Sobriety” initiative breathalyzers tens of thousands of people every day in an effort to curb drunk driving. Rather than legislation that takes penalizes offenders by taking away their license, the state addresses the behavioral issue instead. In counties that use the “24/7 Sobriety,” they’ve seen a 12% decrease in repeat drunken-driving arrests.
