Solid introduction to the need to revise our thinking about the drawbacks of our environmentally catastrophic mega-scale approach to food in favor of small, sustainable, local, organic systems.
Agriculture is responsible for 13.5% of global greenhouse gas emissions – largely from synthetic fertilizers and large animal operations. GHG emissions-soil carbon loss, methane, and nitrous oxide-are largely results of large-scale agricultural operations in which soil carbon is depleted, methane from large animal feedlot operations is released unchecked, and synthetic fertilizers release nitrous oxide-a gas with 300 times the warming power of CO2.
The agricultural sector, including land use change for agriculture, has been estimated to make up anywhere from 28-33% of global emissions. Combined with the emissions created transporting food in our increasingly globalized food economy where the average bite to eat travels 1200 miles from field to fork, the industrial food system may be the largest single contributor to global warming.
Small-scale sustainable agriculture is also vastly more resilient to climate change. After Hurricane Mitch devastated much of the Central American countryside, a study of over 1800 conventional and sustainable farms showed that farmers using sustainable practices suffered less “damage” than their conventional neighbors. Diversified plots had 20% to 40% more topsoil, greater soil moisture, less erosion, and experienced fewer economic losses than their conventional farm neighbors. Not only can small-scale sustainable agriculture help cool the planet, it can provide a buffer against the worst effects of global warming.
Any “vision” that may emerge from negotiations in Poznan, Poland this week must include creating a food system that is more resilient, less polluting, and ultimately more just. Peasant farmers, who comprise more than half of all farmers worldwide, have much to offer a warming world. The fact that greenhouse gas emissions from agriculture was on the agenda of farmers themselves before it is talked about on the world policy stage should send a strong message to Poznan: It is time we opened the climate debate to the ills of industrial agriculture, and the home-grown solutions that could save us.
We must face the negative impacts of global agri-biz, with an intent to refocus on the cost-effectiveness, and sustainability of locally-grown, organic agriculture. Affordable, culturally appropriate food, clean water and clean air are fundamental human rights. Isn't it ironic that most online news stories come with built-in ads for diets or how to "flatten your stomach" while the poor villagers who harvest crops to be shipped to our stores are starving?
