Mexico's Floating Gardens Are an Ancient Wonder of Sustainable Farming

The Green Revolution in Asia and Latin America never spread to Africa, due to the continent's varied climate, degraded soil and lack of infrastructure. Now, scientists look to develop a high grossing wheat seed to bring a new green revolution to Africa. The seeds are extremely promising, but there are still some challenges to getting farmers to implement the seeds.

Officials in Niger are addressing chronic severe droughts causing food shortages and leading to a widespread threat of starvation. They provide aid to malnourished children and resources for a crop planting technique called 're-greening,' which aims to reforest agricultural regions, restore soil quality and, in turn, increase food supply.

Most insurance companies avoid insuring poor farmers because the transaction costs are too high, but a non-profit in Kenya created a sustainable way to cover them.

In prison, most inmates are alienated from social practices and can be a tax burden for the states. The Colorado Correctional Industries is a program that positions inmates in different forms of labor such as making stuffed toys, farming fish, picking fruit, tending livestock, and creating crafts to be sold at grocery stores. The program makes inmates into taxpayers instead of tax burdens and offers skills that are useful for future employment once they leave prison.

In Colombia, traditional cattle pastures have caused soil degradation, deforestation, and desertification. To reconcile this, several thousand acres of land in Latin America have been transformed into a silvo-pastoral system of grazing and raising cattle with agro-forestry. The Colombia-based Center for Research in Sustainable Systems of Agriculture seeks to reduce pasture land by 26 million acres while increasing cattle numbers by 2019.

Soil in Bangladesh is becoming increasingly saline and infertile due to climate change. Bangladeshi farmers have begun using a saline-tolerant rice seed in order to produce an abundant crop despite salty soil.

Through creative financing and new technology, a non-profit in San Francisco is making farmers markets more accessible to residents who rely on federal nutrition benefits.

America is the world’s main supplier of food aid to impoverished countries; however, food aid has the problems of long-distance transportation, the cost of the transportation and storage, and the navigation through dangerous zones. Different programs around the world are experimenting with alternative forms of aid, including vouchers and cash for work.

The non-profit Root Capital created a lending initiative in Mexico which helps mid-size rural farmers gain access to capital, skills, and consumer markets from which they would otherwise be excluded.

A robust population of grizzly bears can be an indicator of healthy land; however, the bears also can destroy grain bins, consume vegetation, and kill livestock. Ranchers work with the Canadian government and local conservation groups to protect their resources with bear-proof grain bins and electric fences.
