Peru is tackling water scarcity with nature-based solutions, leading the way in Latin America

A new effort involving just about anyone who flushes a toilet from Lino Lakes to Woodbury is about to eclipse the scattered sprinkling limits and water-saving campaigns to rescue a shrinking White Bear Lake.

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.

Fariel Salahuddin was determined to tackle the extreme lack of access to fresh water she encountered in rural Pakistani communities, but she wanted the model to be sustainable, not dependent on donations. Most of the communities didn't have regular access to rupees to help sustain their solar water pump micro-enterprises - what they did have, however, were goats. Salahuddin set up a scheme where villagers could pay for their clean water access with livestock instead of cash, which she then sells using Facebook at high rates during Muslim festivals to generate a sustainable revenue source.

On World Toilet Day in 2014, the Kenyan government promised to build 180 public toilets in an ambitious move to combat the issue of public sanitation. The program went well once the keys were handed off to the National Youth Service of Kenya as a means of income, but issues quickly arose that could not be resolved because of a lack of further funds. The youth has since transformed their toilets into a rental space for local churches, such as Christ Miracle Church for All Nations in Laini Saba.

In Arizona, the use of drones as farming technology is gaining traction. While still in the early stages, drones have shown to help with field mapping and data collection on things like crop conditions, water quality, and infestations. In an area that has been experiencing a 2-decade drought, these drones are able to help identify more precisely the water needed for soil.

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

The state of Pennsylvania set to plant 86,000 hectares of riparian buffers, the practice of planting trees and shrubs along a river or stream to filter water. Other benefits of riparian buffers include things like restoring the soil and cooling the water. In order to meet their goal, the state scientists used a bottom approach, enlisting the help of local farmers by offering them grants to plant trees and showing farmers how they can profit off of riparian buffers. While the state is behind its goal, the state is planting about 1,000 to 2,000 hectares a year.

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.

New solar-powered irrigation systems in the Chotanagpur Plateau region in India are giving farmers more dependable water and allowing them to diversify their crops, allowing them to also grow their income. Many farmers from a local village used to migrate to other places to search for work, but a new irrigation system has allowed them to grow cauliflower for a competitive price. While the cost of buying and installing a solar-powered irrigation system can be high, this form of irrigation could be more climate-friendly and help stabilize crop production.
