  • 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.

  • Coastal Recovery: Bringing a Damaged Wetland Back to Life

    A coastal recovery project in Delaware Bay is using a technique that they call "engineering with nature" to bring back the 4,000 acres of wetlands from the disastrous effects of human interference and climate change. They use a multitude of strategies, such as stabilizing the dunes and replanting native grasses, and although they approach the project as a research study without progress yet, they have already begun to see a return of wildlife including birds, eels, and crabs. Similar efforts to restore wetlands are also taking off across the globe.

  • Agrobiodiversity initiatives open women's horizons in Kerala

    The Kudumbashree Mission aims to encourage agrobiodiversity projects in India and empower women farmers. These projects revive traditional and sustainable farming practices called “panchakrishi.” So far, there are 192 hamlets and over 840 hectares under this type of farming, producing pulses, tubers, paddy, millets, and vegetables. While climate change has caused a lower crop yield for some farmers, pancharkrishi has helped women diversify their crops and maintain nutritional security.

  • Can charcoal make beef better for the environment?

    An unusual mixture of biochar — a charcoal-like substance that is produced by burning organic matter — and dung beetles is one way farmers could reduce their cows’ methane emissions to combat climate change, while also improving the health of their soil. Studies on Doug Pow’s farm in Australia have shown an improvement in soil-water retention and an increase in the amount of carbon retained in the soil, which prevents it from escaping into the atmosphere. “We are doing our bit to re-engineer the soil in a positive way, for the long-term benefits of our world,” Pow says.

  • Copenhagen Wants to Show How Cities Can Fight Climate Change

    Copenhagen is doing its best to become net carbon neutral by 2025. With strong leadership from Mayor Frank Jenson, the city has installed wind turbines, a trash incinerator that also helps heat the city, and stronger bike lanes. Without national support, however, the city is fighting an uphill battle to protect itself from climate change.

  • They Know How to Prevent Megafires. Why Won't Anybody Listen? Audio icon

    California’s wildfires historically were contained through periodic but limited burning. But “misguided fire police” over many decades, focused on overzealous fire suppression, has accumulated more dry fuel, resulting in wildfires that have grown progressively larger and more dangerous. Climate change only increases the likelihood of more fires. And the inventory of unburned acreage that has accumulated is now so great that it makes it increasingly difficult to ever catch up.

  • For a Warming World, A New Strategy for Protecting Watersheds

    As climate change alters environments across the United States, it has become increasingly important to manage watersheds as a preventative measure to wildfires. Amid responses across the country, one private-public partnership, the Rio Grande Water Fund, is leading the way, demonstrating enough success that the model has become federal policy. The Fund brings together government agencies, NGOs, businesses, and residents to fund watershed restoration which, in turn, creates jobs and build more resilient ecosystems.

  • A New Weapon Against Climate Change May Float

    Floating wind turbines off the coast of Portugal is one of the latest experiments to convert wind energy into electric power. These machines can generate electricity for a city of up to 60,000 people. While it will take more financing and time to scale the project, investors are impressed with the results and see it as a viable financial return to combat climate change.

  • Can an Algorithm Help Solve Political Paralysis?

    Citizen assemblies bring together residents for in-depth discussions about solutions to social issues. This alternative form of democracy led to policy changes in many countries, including legalizing abortion in Ireland. In the UK, an algorithm was applied to form a 110-person “climate assembly.” In a multistage process, the algorithm selected a representative sample of the U.K.’s population, sometimes oversampling harder to reach groups to ensure inclusion. A small stipend was also offered to offset costs for people with lower incomes. The group submitted a final report with climate policy recommendations.
