The Big Idea: using AI to breed more sustainable crops

Wolves in western America were once hunted to near-extinction but have now been reintroduced into certain territories with notable success. More wolves often means more attacks on ranchers' livestock, however, so cowboys are working to track wolf packs by computer to reduce conflicts.

Concerned with colony collapse syndrome in honey bees worldwide, scientists, farmers and tech companies teamed up in Australia to create a micro-sensor that collects data on the bee's environment.

By supporting small-scale female farmers, Groundswell International, an NGO, is diversifying diets and combating food insecurity in countries in West Africa.

The U.S. Department of Agriculture assists farms which follow the sustainable farming style, Silvopasture, but few farmers take advantage of the program. ForeverView Farms in Vermont is advising policy groups about ways they can boost this type of farming.

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.

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.

When cattle die on ranches in Montana, they can attract grizzly bears that can come dangerously close landowners, ranches, and living livestock. Blackfoot Challenge, a coalition of ranchers and landowners who work with the government, collects and composts dead cattle into odorless woodchips. These woodchips are effective at repurposing carcasses into high-way side revegetation projects.

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.

The demand for food crops is increasing globally while the crop resilience is decreasing due to a warming climate and elevated CO2 levels. Scientists in Washington, DC are testing how to cross food crops with weeds, which have resilience against heat and many other environmental challenges.
