A first in Minnesota, cities launch system to treat, stash water underground

Billions of people around the world lack access to safe sanitation, causing disease and deaths. In Ecuador a foundation developed a cheap, dry, composting toilet for poor rural families.

As climate change continues to advance, its impact on farmlands has become more pronounced and increasingly devastating. Farmers and researchers in both South Africa and Nepal are working towards solutions to problems specifically related to climate change. Centered on developing technology, these farmers have found success with NASA satellite imagery as well as local clinics.

Uganda’s education ministry requires all schools to have incinerators to burn used sanitary pads. Lack of funding limits schools’ ability to comply. Even when incinerators exist, girls don’t necessarily use them. Educating both girls and boys about menstruation reduces stigma and increases the likelihood that girls feel comfortable enough to collect pads instead of throwing them in pit latrines.

The simple addition of adding handles to bathroom stalls in the Rohingya refugee camps in Bangladesh has helped the camps' pregnant women regain a sense of empowerment and dignity. Providing support and balance, the design of these latrines have benefited the elderly in the camps as well.

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.

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.

A unique partnership between environmental groups and governments in the United States and Mexico has led to the resurrection of wetlands and forests in the long-dry Colorado River Delta. Since the waters were dammed and diverted in the 1900s, estuaries dried up and vegetation was lost. The two nations agreed to rewet the delta via a planned flood. Even though there isn’t enough water available to restore a flowing river, these restoration projects on parts of the delta have shown promise. Challenges, including limited funds and hotter, drier conditions due to climate change, remain for its longterm success.

As climate changes causes seawater to flood land and increase the salt content in soil, farms in Scotland and the Netherlands are experimenting with using the saltwater to grow food. Seawater Solutions is growing crops called halophytes that have a high-salt tolerance and can be eaten or used as material for cosmetics and biofuels. And the Salt Farm Foundation has shown that potatoes, cabbage, and tomatoes can grow in saltwater. These projects can labor intensive, but seawater irrigation could be a viable climate adaptation solution.

Natural Sequence Farming is the process of restoring a landscape's original hydration processes by "reading the landscape and tapping into the land's natural system of self-rehydration," – and it's helping Mulloon Creek Natural Farms in New South Wales revive dry farmland. Although some, including the government, haven't entirely accepted the practice, the pilot project has shown a "63% increase in production on the hydrated land."

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.
