Tucson's water ethic: Blueprint for Minnesota?

Tucson has slashed its per capita water consumption by more than a third, and one of the more startling ways it's done that is by reusing water after it's flushed down the toilet or run through a washing machine.

Water:Charity assumed that money and celebrity exposure would be able to solve the world’s access-to-clean-water crisis. But this approach often led to more abandoned water pumps. Charities – and journalists who cover them – are now working to concentrate on making their solutions sustainable.

Farmers in Vietnam face rising sea levels but rejected the city's water engineering projects. They prefer gradual measures to cope with climate change so scientists have allowed the farmers to steer the conversation.

Raton, a town once surrounded by eight coal mines, now has a main street of boarded-up buildings. There is reason for optimism as the town diversifies its local economy, betting on "a mix of small manufacturing businesses, health care and specialty services, and hospitality for travelers" to endure the sudden decline in mining revenue. Its calculated revitalization may hold lessons for other towns.

Climate change has led to shorter, more violent rainy seasons in the highlands around Lima, Peru, meaning that - even though there is theoretically enough water during the rainy season to sustain the local population, it flows downhill too quickly, leaving residents short of clean water during the dry season. Now, an organization called Condesan is helping the community to restore ancient stone canals from the seventh century that will help to store water from rainfall through the dry season and supply residents with a steady water source.

Enrolling indigenous knowledge in environmental conservation programs empowers communities and promotes responsible land management. Conservation programs in Australia and Canada rely on indigenous communities to monitor and maintain remote and protected areas. Investment in these programs not only furthers the goal of environmental conservation, but also pays dividends by bringing jobs to indigenous communities.

A group called Backcountry Hunters & Anglers, now 36,000 strong, is bringing together people from different political and ideological backgrounds over a common interest in the preservation and conservation of public lands and waters. Bucking stereotypes, the group spans the political spectrum, with 33% Independent, 23% Republican, 20% Democrat and 16% unaffiliated in a recent survey. The BHA's recent promotion of the Land and Water Conservation Fund shows that bipartisanship is possible.

A grass blend formulated specifically for northern Utah’s environment uses at least 30 percent less water than typical turf.

In Indonesia, there are 27 “Guardian” sensors eavesdropping on forests as a way to monitor them for cases of illegal logging. The organization Rainforest Connection uses artificial intelligence to analyze the audio from these sensors and if the system picks up the sound of a chainsaw, it sends a mobile alert to community patrols in the area. This technology can be scaled for other parts of the world and habitats. “We're basically building a nervous system for the natural world," says Topher White, founder of the nonprofit.

Lamakani, a small village in India, went barren and townspeople completely depended on water tankers after a drought in the 90s. One leader initiated a watershed movement. They applied a series of approaches which included things like watershed development, bans on grass grazing and tree falling, and collaborating with local artists to communicate messages of conservation. Now, the town is lush again.
