  • Bogota crowdsources a green transport future to cut emissions

    Citizen participation in meetings, door-to-door surveys, and via an open-source online platform where residents could edit and add to draft plans resulted in 7,000 citizen proposals to redesign one of Bogota’s major, car-choked, 23-km thoroughfares. Residents as young as 10 years old contributed to design plans that will cut climate-changing emissions and pollution by adding more bike lanes, pedestrian paths, and electric buses and cable cars. City officials spent substantial time listening to residents’ ideas and concerns, including talking with populations that are often ignored by those in power.

  • Crypto power: Can solar boost cheap, green homes in S.Africa?

    Watergate Estate is working on two issues in South Africa: affordable housing and renewable energy. The housing development is installing solar panels for its residents that are being bought by people all over the world using cash or bitcoin as a way to offset their own carbon costs. Not everyone agrees that gated communities like this are helping to fight social inequalities, crime, and unemployment, but about 470 people bought solar cells for the apartment complex and some residents say they feel safer in their community.

  • Solar lights help Kenyan women escape sex-for-fish trap

    A renewable energy project in Kenya is empowering women to catch their own fish instead of relying on “sex-for-fish” deals. Previously, men used to control the mechanisms for catching fish and would only sell to women who would have sex with them. About 400 women have received free solar lights, which allows them to fish at night. The batteries are lightweight and can run up to 120 hours on a single charge. For one woman, using the light also enables her to keep her fish stall open longer, earning her 10 times more than what she used to.

  • Treetop sensors help Indonesia eavesdrop on forests to cut logging

    In Indonesia, there are 27 “Guardian” sensors eavesdropping on forests as a way to monitor them for cases of illegal logging. The organization Rainforest Connection uses artificial intelligence to analyze the audio from these sensors and if the system picks up the sound of a chainsaw, it sends a mobile alert to community patrols in the area. This technology can be scaled for other parts of the world and habitats. “We're basically building a nervous system for the natural world," says Topher White, founder of the nonprofit.

  • Egypt's farmers tap new tech to save water and boost crops

    A new government pilot program in Egypt is allowing farmers to use technology to tell them when their soil is dry and how much water it needs, which can aid the country as it navigates its water crisis. Sensors buried in the soil measure the ground’s moisture levels and sends the data to the user through a mobile app. The government has given 200 devices away for free, but some experts question the cost and if farmers will be comfortable with the technology. Still, one farmer says that because of the new system, she has been using 20 percent less water and her labor costs have also decreased.
