The great African regreening: millions of 'magical' new trees bring renewal

At the Fujitsu factory in Japan, a significant decline in demand for semiconductor computer chips meant the company had large empty factory space sitting unused. A new business approach allowed them to dually address both the need to evolve their business model with a global decline of viable agricultural space needed to grow the world's food. Now, the factory houses indoor vegetable gardens, soil free and less resource-heavy than traditional farmland.

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.

Climate change has led to shorter, more violent rainy seasons in the highlands around Lima, Peru, meaning that - even though there is theoretically enough water during the rainy season to sustain the local population, it flows downhill too quickly, leaving residents short of clean water during the dry season. Now, an organization called Condesan is helping the community to restore ancient stone canals from the seventh century that will help to store water from rainfall through the dry season and supply residents with a steady water source.

To combat extreme weather, pests, and disease brought on by climate change, the Heritage Grape Project produces wines that aim to conserve and promote hybrid grapes, which are becoming a beneficial option to help local viticulturists grow grapes in an ecologically and economically sound manner.

In the wake of more than 100 forest fires in Maule, Chile, hundreds of burned acres of forest are being replanted by three Border Collies named Das, Olivia, and Summer and an organization called Pewos. The dogs bound through miles of terrain with special backpacks that release native seeds to regrow the area. So far the dogs have worked in 15 forests in the region and plants are starting to come back.

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.

In Indonesia, there are 27 “Guardian” sensors eavesdropping on forests as a way to monitor them for cases of illegal logging. The organization Rainforest Connection uses artificial intelligence to analyze the audio from these sensors and if the system picks up the sound of a chainsaw, it sends a mobile alert to community patrols in the area. This technology can be scaled for other parts of the world and habitats. “We're basically building a nervous system for the natural world," says Topher White, founder of the nonprofit.

A blue carbon credit scheme in Kenya is not only restoring mangrove forests, but it’s also reducing environmental crimes and providing a way for residents to make money. The Mikoko Pamoja carbon project is a partnership that encourages the protection of mangroves in exchange for selling carbon credits. Since the project launched 2013, each year it traps the equivalent carbon emissions of about 650 cars. While it’s not a perfect system, it has inspired other blue carbon programs in other villages.

A startup in California called Crop Swap LA is converting unused front yards into community gardens that can grow crops like kale, rainbow chard, and tomatoes as a way to feed neighbors. Community members can pay for subscriptions for up to $43 a month to receive a bundle of greens and vegetables from the microfarms and homeowners get a share of the profits. Each garden needs to have the proper maintenance, which can make it difficult to scale, but these gardens can help provide access to food to those who don’t have a grocery store in their area.

During rain seasons in Bangladesh, rivers flooded villages and their agriculture so that local economies and food supplies were in jeopardy. A Bangladeshi non-profit Shidhulai Swanirvar Sangstha introduced small floating farms designed to be run by women. Consequently, the organization has initiated 40 floating farms that serve 300 rural women and save local agriculture.
