Bringing back California's wild bees

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.

During the Industrial Revolution, farmers began harvesting monoculture crops which produced promising profits but proved harmful to the soil and weakened the immune capabilities of native plants. Lately, however, permaculture practices have been on the rise amongst farmers to better diversify their yields and reduce reliance on chemicals.

Scalesia, is a species of tree native to the Galapagos Islands that is quickly disappearing thanks to human activity. With much of the island's wildlife dependent on this tree, the ecosystem is threatened with the tree's extinction. Conservationists have taken action, however, by planting thousands of the trees as part of a shade-grown coffee operation.

Communities across Uganda have been realizing the benefits of agroforestry, an old farming system that mimics natural ecosystems. Apart from creating a diverse, stable local food supply, the practice promotes soil health, bolsters biodiversity, creates wildlife habitat, and sequesters carbon. An NGO is working with communities to spread the practice across the region, with marked effect.

As climate changes causes seawater to flood land and increase the salt content in soil, farms in Scotland and the Netherlands are experimenting with using the saltwater to grow food. Seawater Solutions is growing crops called halophytes that have a high-salt tolerance and can be eaten or used as material for cosmetics and biofuels. And the Salt Farm Foundation has shown that potatoes, cabbage, and tomatoes can grow in saltwater. These projects can labor intensive, but seawater irrigation could be a viable climate adaptation solution.

After years of drought and land-clearing that left Niger with few trees left, the country now boasts about 200 million trees, which have mostly been reestablished naturally. While the effects of climate change could threaten the future of these trees, this method has also increased crop yields in villages. This model of letting trees grow back with little human influence could be implemented in other countries.

Surge Africa is a nonprofit helping Nigerian farmers learn about and implement agroforestry and agroecology practices to more sustainably manage their land and improve their yields despite the negative impacts of climate change.

Led by Native Hawai’ians, Kamehameha Schools owns thousands of acres of land dedicated to stewardship and conservation. The school partners with Native Hawaiian organizations and conducts eco-cultural education programs for students and members of the community to foster connections between them and the environment.

Burdened by extreme drought, water diversions, and a lack of regulation, Lake Acuelo in Chile dried up. Now, researchers are learning from this slow-moving ecological disaster to help other lakes in trouble, like Utah’s Great Salt Lake.
