The Saguaro Solution

Refugio, Texas was ravaged by Hurricane Harvey, leaving behind damaged houses, schools and businesses and people who can not afford to rebuild their lives. However, this town has used its community and found strength in their love of football and their support of one another to keep moving forward.

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.

FEMA’s response to Puerto Rico post-Hurricane Irma has been the “longest sustained domestic airborne food and water mission in the nation’s history. The agency has never distributed more food or installed more generators.” However, due to bureaucracy and delayed decision making, there are still thousands of Puerto Ricans who have not received aid, or were underserved.

In countries like Cambodia, Angola, and Mozambique, rats are saving lives by detecting untriggered land mines. An international nonprofit, Apopo, provides funding a training and works with local organizations to operate at the local level. The rats are light enough that they don’t trigger the explosives and can cover up to 2,000 square feet in just 20 minutes – something that would take a human up to four days to complete.

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.

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.

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.

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.
