  • India's tribal farmers tap solar irrigation to cut migration

    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.

  • Up close with B.C.'s endangered baby caribou — and the First Nations trying to save them

    To save the dwindling caribou herds in Canada, the West Moberly First Nations and Saulteau First Nations capture pregnant caribou cows from the herd by helicopter and raise them in pens to ensure the calves are old enough to survive in the wild. Within six years, the herd has grown from 36 animals to 95, but there’s still more to do to stabilize the herd.

  • Is underground farming the future of food?

    There’s a subterranean, organic farm in one of Seoul’s subway stations that could be another way to approach sustainable urban farming. The “vertical” farm, known as Metro Farm, uses a mineral nutrient solution instead of regular soil, and has an automated tech network to control the underground ecosystem’s temperature, humidity, and carbon dioxide levels. While Farm8, the tech startup in charge of the venture, hasn’t made much of a profit yet, the farm produces about 30 kilograms of vegetables per day at a rate that is 40 times more efficient than traditional farming.

  • This tech is bringing water to Navajo Nation by pulling it out of the air Audio icon

    Zero Mass Water partnered with the Navajo Nation to bring water into the homes of rural residents who may not have easy access to a water source. Hydropanels that connect to a tap inside the home use sunlight to absorb enough water vapor to make at least 10 liters of water per day. While people at first were skeptical about the idea during a pilot test, the company and Navajo officials are hoping to scale the solution.

  • Waiting for water: On the Navajo Nation, long lines, scarce resources, a cry for solutions

    As the coronavirus spreads throughout the Navajo Nation, many people don’t have access to water to even wash their hands. For generations, the Navajo people have suffered with this lack of water infrastructure, but some solutions have been implemented. For example, the Johns Hopkins Center for American Indian Health has built about 100 hand-washing stations and delivered them to homes in need. Many people are hopeful they will receive more funding to build a more robust water system, but the scale of the problem and the cost of building it are big challenges to overcome.

  • In green jobs boost, communities get bigger role running Pakistan's national parks

    Khunjerab is the country’s oldest and largest national park and is a model of successful community-led management and conservation. Eight villages inside the park agreed not to graze livestock in a 12-square-kilometer area in exchange for designated grazing areas that rotate so each can recover after being used. Locals get 80% of the park’s employment opportunities and the local communities receive 75% of the visitor-generated revenue. As a result, Marco Polo sheep and Ibex numbers have grown substantially. A new Protected Areas Initiative has been funded to expand conservation efforts using this model.

  • Could a Detroit Experiment Unleash the Power of Urban Soil?

    A multi-year experiment in Detroit is looking at environmentally sustainable ways to build urban soil. Some urban farmers are concerned about the high alkalinity levels in their soils, which can lead to potentially contaminated produce. The project is studying how cover crops, compost, and tillage can improve a piece of land. Early results suggest that these techniques can improve soils for agriculture but also improve the soil’s capacity to absorb carbon to mitigate climate change in major cities.

  • Amid biting drought, sisters in Zambia fend off hunger with organic farming

    In Zambia, where severe drought due to climate change has negatively affected agriculture, the Daughters of the Redeemer are practicing organic farming to feed hundreds of children and families whose basic needs are not being met. This group of religious sisters do not rely on rainfall to farm; they installed a drip irrigation system that has allowed them to grow crops like cabbage, maize, tomatoes, and beans. Before the COVID-19 pandemic, the sisters provided training to local villages about organic farming, and this has allowed families to support themselves during the crisis.

  • Tackling a notorious waste problem in Africa's largest informal community

    Kibra Green, a grassroots organization in Kenya, mobilizes the young people in the community to clean up their neighborhood. At times, the group has as many as 500 participants for a community-wide clean up. Yet, a lack of steady funding and socioeconomic barriers for volunteers to regularly contribute to the group has made it difficult to scale the organization.

  • How the ‘15-Minute City' Could Help Post-Pandemic Recovery Audio icon

    Some cities are using coronavirus shutdowns as opportunities to start infrastructure projects that support car-free living and encourage walking or biking to jobs, shopping, and city services. Car-free urban development benefits the environment, revitalizes cities by keeping resources local, and has become more appealing because of fears of virus spread. Paris, Milan, Tallinn, Ottawa, and Portland are among the cities using coronavirus-related lockdowns to kickstart bike lane and pedestrian zone projects. As the pandemic has decimated city budgets, it is a challenging time to begin infrastructure projects.
