The 'water literacy' lessons cities can learn from Cape Town

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.

Many herders are adapting to climate change by adopting farming. In the wake of severe droughts in recent years, herding communities in Ethiopia have expressed increasing interest in farming as a way to secure additional income. The non-profit organization, Farm Africa, helps herders to make the transition into farming by educating and assisting them with technical matters, such as irrigation, as well as aiding with financing and finding markets.

Getting away from daily publishing helps local newspapers focus on serving their audience. The Quoddy Tides, a family-owned newspaper in Eastport, Maine, publishes only twice monthly. Publishing less frequently allows the newspaper to include more local stories, which are of interest to their community of readers, many of whom either live in, or have ties to the community. By avoiding the 24-hour news cycle, the newspaper can focus on local discourse and civic engagement.

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.

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.

The Women’s Collective is a nonprofit that works with more than 10,000 subsistence farmers in the Indian state of Tamil Nadu to promote food security using millets, a crop resilient to drought and climate change. For Pavitra, one of those farmers, she began cultivating the ancient grains in 2015 and now has more than enough food to feed her family year-round. However, there’s a lack of public investment in millet production and machinery. And there’s no unified effort to create demand for millets: Some state governments lead the charge and in other states, it’s led by grassroots organizations.

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.

Ameelio is a technology startup launched by Yale students to facilitate free communication between people who are incarcerated and loved ones. In their first six months, the group went from sending 300 to over 4,000 letters a week to facilities in the United States. Their initial goal was to provide a not-for-profit alternative to the oftentimes predatory prison telecommunications industry. Recently they began a voter registration initiative where they send registration instructions, a blank voter registration application, and ballot request form to people who are incarcerated and eligible to vote.

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."
