  • These farmers show that agriculture in the Amazon doesn't have to be destructive

    Nearly a fifth of the Amazon has been cleared for cattle grazing and logging. However, a cooperative called RECA is making it economically sustainable for farmers to shift towards agroforestry. Agroforestry is the intentional planting of trees and shrubs in farms and forests among others. 11 tons of carbon per acre are sequestered through agroforestry systems. REFA farmers planted up to 40 species of trees then will process products from the species to be sold. The more than 300 families from the co-op made five times more per acre than local ranchers not practicing agroforestry.

  • Oregon Bottle Bill at 50

    In 1971, Oregon became the first state to adopt a law that established refundable deposits on beer and soft drink containers. So, if a consumer returned their plastic bottle, they would get their deposit back and that bottle then gets recycled. The Bottle Bill turned 50 this year and has proved to be a huge success. In 2019, it had a 90 percent return, meaning nine out of ten containers were being recycled. Other states are looking towards Oregon to replicate the model.

  • Why ‘tiny forests' are popping up in big cities

    In Europe, India, and other countries like the Netherlands tiny forests are being deployed to fight the effects of climate change. The small forests, some about the size of a parking lot or a basketball court, can help cities mitigate rising temperatures and sequester carbon. In the Netherlands, 144 tiny forests have been planted. A study that analyzed 11 tiny forests showed these forests hosted more than 600 animal species and close to 300 plant species.

  • Cleaning up Cambodia's kitchens could curb deforestation, climate change

    In Cambodia 2.5 million people use stoves fueled by forest biomass; charcoal and wood. The emissions caused by using biomass are extremely harmful not only to people but also to the environment. The emissions caused by biomass globally are equal to those of the aviation industry. To counter the problem, several organizations and companies are providing alternatives for Cambodian families like electric stoves. One company, Khmer Green Charcoal, created stoves that run on “clean” charcoal made from coconut shells. More than 6,500 households across the country have made the transition.

  • Chocpocalypse Now! Quarantine and the Future of Food

    Off the coast of Australia, the energy company Chevron is experimenting with new quarantine management techniques to ensure that any plants and pests don’t hitchhike to new places, which can devastate the global food economy. They’ve redesigned shipping containers to make it harder for insects to tag along and they’ve created a video game to train workers on how to be better at finding these pests in their inspections. Some creatures and plants can slip through the process, but these tools have been successful and could be used in other ways.
