The Great Plains prairie needs fire to survive. These ranchers are bringing it back.

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.

In a rapidly gentrifying Mexico City neighborhood, two artists refurbished an icon and set up an altar for Santa Mari La Juaricua, a saint to protect residents from eviction. The saint raises awareness and acts as a reminder about housing issues and the icon has been taken up by the residents and has been used in processions and protests.

Jane Cavarozzi, an entrepreneur and activist, started Dirty Girl coffee to “support economic development and women’s advancement in the small, depressed villages around Appalachian Ohio.” She lives in the town of Glouster and is respected for living local and working local, as opposed to being an outsider problem-solver.

In Londonderry, New Hampshire, the Carriage Shack Farm hire out goats to eat unwanted plants like poison ivy or bittersweet.

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.

The Women’s Collective is a nonprofit that works with more than 10,000 subsistence farmers in the Indian state of Tamil Nadu to promote food security using millets, a crop resilient to drought and climate change. For Pavitra, one of those farmers, she began cultivating the ancient grains in 2015 and now has more than enough food to feed her family year-round. However, there’s a lack of public investment in millet production and machinery. And there’s no unified effort to create demand for millets: Some state governments lead the charge and in other states, it’s led by grassroots organizations.

Fariel Salahuddin was determined to tackle the extreme lack of access to fresh water she encountered in rural Pakistani communities, but she wanted the model to be sustainable, not dependent on donations. Most of the communities didn't have regular access to rupees to help sustain their solar water pump micro-enterprises - what they did have, however, were goats. Salahuddin set up a scheme where villagers could pay for their clean water access with livestock instead of cash, which she then sells using Facebook at high rates during Muslim festivals to generate a sustainable revenue source.
