In Kenya, herders turn an invasive cactus into biofuel

The rapid development of emerging economies across Asia and Africa is lifting hundreds of millions of people out of poverty - but there is much debate as to how to best structure this growth. If these economies evolve in the same way as in the West - with unchecked, excessive resource consumption and heavy pollution - the planet may be on the fast track to disaster. Earthrise explores how these nations can grow sustainably using improved, eco-conscious technologies like renewable energy and eco-friendly farming practices.

With the prices of solar technology dropping and the opportunity to save drastically on energy usage and costs, businesses and organizations across the country are investing more in solar infrastructure for their buildings and facilities. The Better Buildings Initiative of the US Department of Energy is helping by providing guidance and documenting effective approaches and financing for renewables installations - from hotels, to schools, to big box retail.

Solar power is a great advancement for renewable energy, but traditionally relies on connecting to a grid in order to function correctly. So when hurricanes hit Puerto Rico, even those with solar panels lost access to electricity. A micro-grid offers an alternative solution, however, by relying on battery power.

In Londonderry, New Hampshire, the Carriage Shack Farm hire out goats to eat unwanted plants like poison ivy or bittersweet. Contrary to humans, they aren’t harmed by the plant and actually enjoy eating it. Prior to being hired, the farm trains the goats so that their appetites and stomachs aren’t adversely affected.

For years, a rancher in Southern Oregon has been trying to keep a local pack of wolves from killing his livestock, and after many rounds of trial and error and collaborative efforts, a high-tech fence may be the solution. Although the fence isn't cheap, many came forward to help make this a possibility and show their support for a project that united people that historically have stood politically opposed.

To replace lost business and keep their employees on staff, Tasmanian businesses quickly diversified into new product lines to meet COVID-19-related demand. A camera accessories firm that saw nearly all of its sales to the film and TV industries dry up became a manufacturer of face shields. A plastic manufacturer increased its business by turning out acrylic counter-top protective screens. And a whiskey distillery began producing 2,000 liters of hand sanitizer per week.

The South Central Leadership Academy was started in Los Angeles by a college student who believes that gun violence survivors like him should lead the community response in finding solutions to violence. Its first year of paying more than a dozen student survivors to learn community organizing skills succeeded in attracting funding to expand to Nashville, Baltimore, and Atlanta. COVID-19 put the latter two expansions on hold, but LA and Nashville continued with well-attended classes learning remotely. Founder Marco Vargas hopes to turn this startup into a national network of youth leadership academies.

More than 2,700 police departments in the U.S. have crisis intervention teams aimed at responding to mental health crises with fewer arrests and less violence, but the death of Daniel Prude in Rochester police custody offers clear lessons in the shortcomings and misuse of the CIT model. A lack of adequate mental health services across the country, coupled with superficial training of the police, too often means a police response to a crisis will not de-escalate the situation or lead to meaningful help for the person in crisis. A recent study found CITs have not shown they will lower violence.

Pennsylvania law is preventing a Philadelphia neighborhood from converting an empty lot into a solar farm, but community members are working to fight against this by citing neighboring states that are seeing positive impact from similar projects. One such project is in Massachusetts where shared solar energy systems is helping to offset "80 percent of the power needs of a nearby assisted living facility, an affordable housing development, a family-owned hardware store and a non-profit serving those with disabilities."

Solar energy is a clean, cheap, renewable, and land-efficient resource, making it a valuable technology to scale up in the face of climate concerns and clean energy. Diversifying the supply chain for creating and sourcing solar panels can help make solar energy more reliable when faced with geopolitical and human rights issues.
