  • 'Virtual rangers' help South African reserve keep poachers away

    Over 55,000 people have become “virtual rangers,” helping to protect South Africa’s Balule Nature Reserve from poachers. Officials at the reserve teamed up with Samsung and Africam to increase the ability to keep watch over the park, which is home to some of the most vulnerable animals to poaching, including rhinoceros, leopards, and elephants. Camera phones, held in protective cases, are mounted around the reserve and stream images to “virtual rangers” worldwide who have already reported hearing gunshots, which could indicate the possibility of poachers, and seeing trapped animals needing rescue.

  • India trashes 100 million tires a year. She turns them into playgrounds.

    Anthill Creations has built 275 "playscapes" across India, mostly using discarded vehicle tires as the affordable raw materials. In many parts of the country, children lack outdoor play spaces and toys to enliven their play. By "upcycling" some of the 100 million discarded tires the country generates annually and painting them bright colors, the 5-year-old project has benefits ranging from the environment to children's safety and happiness.

  • The mechanical stomach powering homes by digesting old food scraps

    The electricity powering 3,000 Perth homes might have started out as moldy bread and rotting lettuce. The city of Cockburn collects food waste from supermarkets and restaurants to be fed into a mechanical "stomach" that converts the waste to energy. Methane is trapped and used to power electric generators. The remainder of the "digested" food is turned into compost and liquid fertilizer. The operation has recycled 43 tons so far, removing 81,000 kilograms of gases that otherwise would escape landfills and warm the atmosphere.

  • Simple hand-built structures can help streams survive wildfires and drought

    Conservationists, government agencies, scientists, and landowners are working together to restore streams using low-cost solutions from sticks, stones, and even beavers. Restoring these floodplains is important to help communities combat drought and wildfires. In Idaho, scientists relocated nine beavers to Birch Creek so they could help repair the dried-up stream. In three years, the beavers built dams, which helped the creek flow for longer in the summer. This method might not work everywhere, so scientists have also tested stone structures, which also proved effective at improving the ecosystem.

  • What Went Into Building Europe's Largest Floating Solar Park

    Evides Waterbedrijf, a drinking water company, created Europe’s largest floating solar park. They installed almost 3,000 solar panels on an island in the middle of a reservoir that allows it to move with the sun to maximize its energy. This setup generates about 15 percent of the electricity the company uses at the site.

  • Comment des bénévoles ont décidé d'aider les bergers azuréens contre les attaques de loups

    Dans les Alpes, pour aider les bergers à prévenir les attaques du prédateur sur les troupeaux de brebis dans les alpages, l'association Férus met à disposition des bénévoles pro-loup. En relayant les bergers dans la surveillance, ils offrent un peu de répit aux éleveurs, assurent une présence dissuasive. Une initiative qui renoue le dialogue entre pro-loup et agriculteurs souvent opposés au prédateur.

  • Turtle conservation hits the SPOT in North Cyprus

    Thanks to efforts by the Society for the Protection of Turtles and a band of international volunteers, green and loggerhead turtle numbers in North Cyprus are rebounding. Last year, there were more than 2,400 nests counted, a 10-fold increase since their first survey in 1988. There are still challenges in saving these species due to plastic waste, but more locals are recognizing the importance of turtle conservation.

  • Meet the Black Mambas, South Africa's all-female anti-poaching unit

    The Black Mambas are an all-female anti-poaching and ranger unit based in South Africa’s Balule Nature Reserve. They patrol on foot and by vehicle to remove bushmeat snares and look for evidence of illegal poaching activities. They also run the Bush Babies Environmental Education Programme, which teaches local school children about wildlife and conservation. The group combines anti-poaching enforcement with efforts to ensure local communities have food security and understand the economic and employment benefits of tourism as a way to protect wildlife. The Mambas are seen as role models within the community.

  • How to reuse a demolished building

    A warehouse in Switzerland is being transformed into new creative workspaces. The catch: It’s being constructed out of reused building materials. About 70 percent of it is being made from old materials like wood floorboards, steel beams, and windows. A network of treasure hunters are on the lookout for used materials that can be used in constructing these buildings. The workspace is nearly complete and it already has tenants for all of the spaces. They were also able to cut the building’s carbon emissions in half.

  • ‘Our biggest challenge? Lack of imagination': the scientists turning the desert green

    A Dutch group of engineers known as the Weather Makers has an ambitious plan to regreen the Sinai Peninsula — the stretch of desert connecting Egypt to the rest of Asia. Their efforts would restore forests, wetlands, and even adjust the weather for the region. This form of ecosystems regeneration could help with food security and mitigate the effects of climate change. Their process of changing an entire ecosystem can be controversial, but initial tests have shown how this could work on a large scale.
