Healthy soil can be a climate change solution

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.

What we sometimes call the “agri-food system” is broken — just ask farmworkers and food workers (exploited, underpaid), honeybees (collapsing), forested landscapes (fragmenting), the climate (warming), and the ever-growing number of people without access to nutritious food, or the land and resources with which to produce it. But a new branch of sustainability, agroecology, helps farmers and researchers develop farming practices that enhance soil fertility, recycle nutrients, optimize the use of energy and water, and, perhaps most importantly, increase the beneficial interactions of organisms in ecosystems.

In India, many farmers, especially women farmers, have transitioned to organic farming. While it requires a serious set of skills and knowledge, organic farming increases yields and decreases costs by eliminating the need to buy pesticides. The move is both ecological and economical, and the Indian government is trying to spread the solution.

With a global food crisis, farmers look for how to get long-term high yields out of difficult farmland. In Oaxaca, Mexico, farmers farm like a forest, eat low on the food chain, restore damaged land, and have reverence for the planet.

Property rights, circumscribed jurisdictions, and conflicts with neighbors exacerbate Native American efforts to restore tribal land and resources. Some tribes have found success by tapping into a trend of support from the government and conservationists.

Farmland is expensive and scarce in urban areas. In Boston Higher Ground Farm uses green roofs to grow its produce and Grove Lab has designed a cabinet for people to grow their vegetables indoors.

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.

In Australia, the Murray-Darling Basin Ministerial Council was formed after a severe drought to bring together federal, state and regional governments and bridge parochial concerns. It was meant to manage the basin as a whole and end overuse and salinization of farm land, leveraging new technologies to adapt to new realities.
