Communities band together to protect El Salvador's last mangroves

Colombia’s National Development Plan for cattle ranching seeks to reduce pasture land from 94 million acres to 70 million acres while increasing cattle numbers from 23 million head to 40 million. The program focuses on planting trees on grazing land and the "cut and carry method," whereby farmers grow fields of shrubs and distribute the fresh cuttings to cows in pastures. The result is greater cattle productivity and a more eco-friendly farming system.

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.

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.

Portland-based NGO, Micah Challenge USA, uses scripture to reach Evangelicals about climate change. The organization partners with legislation-making initiatives, travels to Christian colleges, and contacts national and local leaders urging them to join the Climate Solutions Caucus. Underpinning every initiative is a core strategy: climate change is causing people to suffer, especially those that are experiencing poverty, and as Christians, they are called to help the poor and end their suffering.

After six years, an international effort to search for wild relatives of various food and plant crops came up with 371 different species that could be helpful for the world’s future food security. While not often found in a kitchen, researchers came across versions of the Bambara groundnut, grasspea, and finger millet. These crops were sent to seed and gene banks around the world that aim to conserve and develop varieties of the species that could provide a more climate-resilient food source.

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.

In Kenya, like other countries in the world, deforestation is the major driver of tree cover loss. To solve this, a local startup called Seedball Kenya has developed the seedball technology whereby seeds of indigenous tree and grass species are coated with charcoal waste mixed with nutritious binders then thrown like balls into the planting grounds.

Beavers and the dams they build have been found to be tools against climate change as the planet’s temperature continues to rise. Dams slow water down and allow it to seep into the Earth, providing groundwater for humans, and also cools down both water and air temperatures. Beaver dams also create wetland ecosystems that are practically resistant to wildfires.
