A shot of recycled water revives a flourishing ecosystem on the Santa Cruz River in Tucson

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.

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.

During the Industrial Revolution, farmers began harvesting monoculture crops which produced promising profits but proved harmful to the soil and weakened the immune capabilities of native plants. Lately, however, permaculture practices have been on the rise amongst farmers to better diversify their yields and reduce reliance on chemicals.

In the wake of more than 100 forest fires in Maule, Chile, hundreds of burned acres of forest are being replanted by three Border Collies named Das, Olivia, and Summer and an organization called Pewos. The dogs bound through miles of terrain with special backpacks that release native seeds to regrow the area. So far the dogs have worked in 15 forests in the region and plants are starting to come back.

Farmers in Iowa have been experimenting with native prairie crops – using native plant species as buffers on farmlands – in an effort to bring more pollination, soil health, water quality preservation, and carbon sequestration to their land. The Iowa State University STRIPS program has been supporting farmers in this effort by connecting them with funding and the information they need to undertake such crops.

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

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.

Scalesia, is a species of tree native to the Galapagos Islands that is quickly disappearing thanks to human activity. With much of the island's wildlife dependent on this tree, the ecosystem is threatened with the tree's extinction. Conservationists have taken action, however, by planting thousands of the trees as part of a shade-grown coffee operation.

After years of drought and land-clearing that left Niger with few trees left, the country now boasts about 200 million trees, which have mostly been reestablished naturally. While the effects of climate change could threaten the future of these trees, this method has also increased crop yields in villages. This model of letting trees grow back with little human influence could be implemented in other countries.

Beavers and the dams they build have been found to be tools against climate change as the planet’s temperature continues to rise. Dams slow water down and allow it to seep into the Earth, providing groundwater for humans, and also cools down both water and air temperatures. Beaver dams also create wetland ecosystems that are practically resistant to wildfires.
