Compared to large-scale industrial farms, small-scale agroecological farms not only use fewer fossil fuel-based fertilizer inputs and emit less Greenhouse gases (GHGs), including methane, nitrous oxide and carbon dioxide (CO2), but they also have the potential to actually reverse climate change by sequestering CO2 from the air into the soil year after year. According to the Rodale Institute, small-scale farmers and pastoralists could sequester more than 100% of current annual CO2 emissions with a switch to widely available, safe and inexpensive agroecological management practices that emphasize diversity, traditional knowledge, agroforestry, landscape complexity, and water and soil management techniques, including cover cropping, composting and water harvesting.
Importantly, agroecology can not only sequester upwards of 7,000 pounds of CO2 per acre per year, but it can actually boosts crop yields. In fact, recent studies by GRAIN (www.grain.org) demonstrate that small-scale farmers already feed the majority of the world with less than a quarter of all farmland. Addressing climate change on the farm can not only tackle the challenging task of agriculture-generated GHGs, but it can also produce more food with fewer fossil fuels. In other words, as the ETC Group (www.etcgroup.org) has highlighted, industrial agriculture uses 70% of the world’s agricultural resources to produce just 30% of the global food supply, while small-scale farmers provide 70% of the global food supply while using only 30% of agricultural resources.
