Ethiopia has made a lot of encouraging progress in recent years, but despite two decades of economic growth, its economy is still struggling. The nation has one of the world's lowest GDPs per capita, and many Ethiopians still rely on subsistence farming. 29-year old tech entrepreneur Selam Wondim is up to the challenges facing her home country, however. And recent changes on Ethiopia's political horizon, including the election of Prime Minister Abiy Ahmed, have her feeling optimistic.

These days, young Ethiopians are looking more and more to technology–and it's not in search of the latest food delivery app. Where much of new technology in the West is convenience-driven, in Ethiopia people are still reliant upon technology to solve v...

When Joelle Eyeson and her organization Hive Earth set out to address housing problems in Ghana, their goal was to provide structures that were both eco-friendly and affordable. For instance, building with cement is especially bad for air quality in Ghana's hot climate, so they came up with an alternative: their "rammed earth" technique combines laterite, clay and granite chips for a cheaper, more sustainable material that eliminates 95% of the toxic cement.

This is just one of the innovations they are incorporating into their homes to make them not just more sustainable, but more livable as well. They've also come up with a ventilation method that utilizes a solar pump, an arrangement that costs $300 to install–and nothing to opera...

Papua, New Guinea is a country of more than 8 million people, but most would be hard-pressed to point it out on a map. That isolation, caused by years of colonialism and exploitation, makes it very difficult for citizens to find markets for their products.

In a very welcome development, an influx of new venture capital is being directed to companies dedicated to the elimination of food waste. According to a recent report by ReFED, more than $125 million has been invested in the category so far in 2018.

Food waste and food access have long been a focus here at Billions Rising–and with an estimated $218 billion of food going to waste each year, that's hardly a surprise. The problem of food waste in particular has now become a hot topic among VC firms, including such major players as S2G Ventures. As pointed out by Chuck Templeton, S2G's Managing Director,"Food waste is a huge problem hidden in plain sight,” and it offers huge potential gains for both investors and the public at la...

When Ken Jacobus quit his Silicon Valley job to set up Good Start Packaging in 2009, he had little knowledge of the packaging industry, and less than $10,000 in inventory. To make sure every dollar went as far as it possibly could, the entrepreneur did the only sensible thing: he did everything himself. He took on sales, admin, management and even the delivery of product.

Today, Jacobus' company is changing the way that restaurants handle packaging, and helping to create a new sustainable paradigm for the fast food industry. To find out how, read the brand-new Forbes article here.

One of the most severe impacts of climate change is the scourge of drought. Drought affects rural farmers' ability to make a living and provide for themselves, and threatens the wider food supply. Solar stills have shown great promise as a way to insure fresh water supplies, but they are typically inefficient. Engineer and social entrepreneur Alessandro Bianciardi has been working on the problem, and has been making immense progress by looking at one of the greatest powers of nature itself: mimicry.

Plastic pollution is a growing problem in our oceans, and an issue that doesn't get nearly enough attention. Plastics are known to cause problems for numerous marine animals, including sea turtles, seals and seabirds to name just a few. Worse yet, aquatic microorganisms mistake plastic particles for food. It’s estimated that approximately 700 different marine species are threatened with extinction due to plastic waste.
