  • With the Hippo Roller, a revolution in fetching water rolls on

    After realizing the difficulty that people in South Africa were facing when carrying water back to their communities, two South African engineers devised a machine "that brings all the water back in one trip by rolling it." Users report that while it does not perform well on steep terrain, it can carry much larger amounts of water "effortlessly and in a single trip." So far, 60,000 of these large plastic drums have been sold, but the cost of the machine is often a barrier for those who live below the poverty line.

  • How Vancouver is protecting itself from future flooding — with plants

    Large cities like Vacounver and Seattle are increasingly leaning towards "green infrastracture," a method of managing stormwater through natural systems like green roofs and rain gardens that absorb rainwater. Cities have traditionally relied on traditional sewage systems, but in the face of climate change, and more intense storms, its proving to be inadequate. Green infrascture lowers flood levels, filters out pollutants in the water, and regulates city temperature. In Seattle, an early adopter of green infrastructure, rain gardens absorbed 1.5 trillion liters of rainwate.

  • Fridge detectives

    In the first half of this episode, the producers discuss "Tradewaters," an organization that disposes of canisters inside refrigerators. These canisters hold potent greenhouse gases. One 30-pound canister can leak up to 131 tons of Co2, or a year's worth of driving for 54 cars. The organization disposes of thousands of canisters across Central America, Chile, South Africa, and India. The practice of disposing of these canisters saves between one to two percent of global Co2 emissions, according to estimates.

  • Why these farmers are welcoming muskrats, birds, and snakes

    In Canada, farmers are rewilding their farmlands, a process where a farmer restores their habitat to a more natural state. It includes things like planting trees, building hedgerows, and creating ponds. Rewilding can prevent soil erosion, carbon sequestering, and filtering water, among many other things, reversing some of the adverse effects caused by farming. One non-profit, the Alternative Land Use Services is funding these rewilding projects by paying farmers. ALUS projects span 31,000 across Canada.

  • In Assam, ATMs purify arsenic-laced water

    A water management committee manages Barigaon’s water ATM, which uses a nanotechnology-based ion exchange resin to remove iron and arsenic from groundwater. Residents, who swipe a pre-paid card to collect water in their own containers, pay 40 cents per 20 liters or a flat monthly fee of less than $3. Water is free for families who can’t afford the fee and delivery is arranged for those who are unable to transport water. Around 250 villagers use the ATM each day and its success inspired five additional ATMs, with plans to install 172 statewide. Fees cover maintenance and the landowner’s electricity costs.

  • Virginia project helps low-income homeowners ditch fossil fuels

    Two organizations partnered to help eight low-income households convert their homes to become all-electric in Virginia. It entailed replacing fossil-fuel based heating and cooling systems like stoves and water coolers with electric ones. Some of the households saw a reduction in their utility bills. Organizers estimate that over the course of 20 years the changes will result in the households avoiding the emission of over 2 million pounds of carbon dioxide.

  • Latest student-built tiny home, now merely small, rolls off to a permanent location in Bridgewater

    High school students from several schools got hands-on construction experience by building tiny homes that are then sold at under-market prices to people needing housing. The training is provided to the students at Huot Technical Education Center, with mentoring from volunteers from the building trades. Four houses have been built and delivered so far in the program, which was slowed but not stopped by pandemic restrictions.

  • The Gila River Indian Community innovates for a drought-ridden future

    Through settlements, the Gila River Indian community was able to regain rights to its river and tributaries. Aside, from that the community created partnerships with other water projects. The community also decided to keep a network of managed aquifer sites and to rehabilitate existing wells. One other effect of the settlement was the revival of a small segment of the Gila river. The strategic moves the community made could provide a model for other indigenous communities who lack access to their own water supply.

  • California Has Farmers Growing Weeds. Why? To Capture Carbon

    Richer soil not only retains more water and minerals, it also trap carbon from the atmosphere absorbed by plants. As California works to meet its carbon neutral goal, the state is enlisting farmers in its climate change strategy. Grants from the state encourage California’s farmers to grow plants traditionally considered as weeds as a way to boost the amount of organic matter in the soil.

  • Boise Is Tapping Into Free, Sustainable Energy - and Other Cities Could Follow Suit

    In the late 1800s a local water company found hot springs in Boise. They decided to build pipes and transport the water to some nearby homes and towns to heat them, creating a geothermal heating system. In the 1980s, the city replicated this model at a larger scale. Water from a naturally hot aquifer flowed through pipes heating 100 large buildings Downtown, equivalent to more than 6 million square feet. Geothermal heating is completely clean, it requires no fossil fuels. Currently, there's only 23 geothermal districts in America. However, one study estimates that by 2050 there could be 17,500.
