  • 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.

  • 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.

  • 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.

  • Could leaving 'room for the river' help protect communities from floods?

    While many communities in the Midwest use dams and levees to control the Mississippi River, some are trying new approaches to flood control as climate change threatens to increase rainfall and the severity of storms in the region. Some cities are turning to the Dutch solution of leaving “room for the river” to allow the body of water to flow naturally and design public spaces to handle inundation. While this technique doesn’t always work during major flooding events, traditional flood control strategies can be more harmful and actually worsen flooding.

  • The revolutionary boat powered by the ocean

    Since the Philippines relies on boats to transport people and goods across the island nation, a shipbuilding company is designing a new low-carbon alternative of the bangka — a traditional Filipino boat — that uses the waves of the ocean to power it instead of fossil fuels. The ship, known as the trimaran, uses wave energy that converts into electricity for the ship. However, a typhoon and the COVID-19 pandemic have delayed the project, and there are also cost and design challenges. But the trimaran’s use of wave energy could be a step toward reducing the country’s greenhouse gas emissions.

  • Will Your Next Salmon Come from a Massive Land Tank in Florida?

    A Norwegian firm has built a land-based fish farm – which is "a supersized aquatic version of greenhouse agriculture that aims to solve a host of environmental problems plaguing conventional salmon farms in coastal waters" – near the tip of the Florida peninsula. Although it's yet to be seen if demand will be to the scale necessary to deem the endeavor financially viable, in Denmark where this concept was initially piloted, more than 25 generations of salmon have already been harvested.

  • Going ‘Deep Green,' Office Buildings Give Back to the Planet

    More and more commercial real estate projects are popping up around the United States that are focused on “deep green” building. This movement suggests that it’s not enough to just make a building out of renewable materials, but they can also be self-sustaining. For example, the Watershed, an office building in Seattle, has a slanted roof that collects rainwater that is then used in toilets. These types of projects can be more complicated and expensive to build, but developers can save money in the long run with the improvements.

  • Blockchain technology to boost power access in rural areas

    A micro-grid system has been paired with blockchain technology to easily sell and buy affordable and clean energy in rural Kenya. Residents living in the countryside don't generally have access to reliable and affordable electricity but this new technology allows rural Kenyans to install solar panels on their homes and easily sell surplus electricity to neighbors. The pilot program is a result of a collaboration between an NGO and a local tech company.
