Reducing Greenhouse Gases & Nitrogen
Roots of Change (ROC) is committed to creating a sustainable food system in California by the year 2030.
ROC believes that among several other key dynamics, the food system will not be sustainable until agriculture greatly reduce and/or eliminates its huge impacts on climate, air and water pollution. Emissions of greenhouse gases (GHG), particularly nitrogen, are a prime crosscutting indicator of the degree of integration with natural systems, agriculture has achieved. Today, GHG emission levels indicate tragedy lies ahead. They must be quickly lowered. We join with a host of other NGOs and foundations in seeking to lower emissions 20% by the year 2020.

Climate Change and the Food System
"Agriculture is an undervalued and underestimated climate change tool that could be one of the most powerful strategies in the fight against global warming." The Rodale Institute
When you think about climate change, are agriculture and the food system top of mind as one of the primary causes? Maybe not, however the most recent UC Davis study suggests that the food system is responsible for up to 29 percent of global warming generated by the consumer economy in industrialized nations (1). Agriculture's dependence on carbon-based energy to manufacture fertilizers and pesticides, and to run farming, processing, and transportation equipment is responsible for part of the emissions in the food system; along with livestock related emissions, and the transportation, storage, and waste of food along the supply chain.
Check out the resources, articles, and profiles below for more information about the connection between the food system and climate change.

Nitrogen, Farmers, and the Environment
The common agricultural practice of adding nitrogen to the soil can boost crop production, but can also lead to fish die-offs, air pollution, and possibly threaten the health of the soil. Many farmers would like to implement more environmentally beneficial practices, but do not for fear of reduced profits, due to potentially lower yields in the field, in an era of low margins. To meet the environmental challenge, the federal government is taking a leadership role in reducing nitrogen pollution in waterways, while two nonprofit organizations work directly with farmers to provide risk reduction and financial incentives to reduce nitrogen use.
Check out these articles for more information on farmers efforts to benefit the environment.
To Reduce Nitrogen Pollution, We Need New Farm Policies - Grist.org
California-based Sustainable Conservation is meeting the challenge of nitrogen surplus by offering incentives to farmers who want to improve their environmental practices. Sustainable Conservation Senior Program Manager – and Roots of Change Fellow – Ladi Asgill offers risk coverage to California dairies enrolled in the Best Management Practices (BMP) Challenge to address potential loss of income as they implement new practices. The National Sustainable Agriculture Coalition praises the program for short-term impact but would like to see more support for widespread systemic changes in how dairy farms, and other farming systems, operate.
AFT’s BMP Challenge - Farmland.org
American Farmland Trust (AFT), recognized as a leader for saving America’s farm and ranch land, promoting healthy farming practices and supporting farms and farmers, began the BMP Challenge (described in the story above) with the belief that the practices can help both the environment and the farmers’ bottom-line. An outcome of the program is that many participating farmers have extended their practices to additional acres not covered by the BMP Challenge performance guarantee once they see the results for themselves. One of the key outcomes is a reduction of nitrogen pollution.
EPA Cracking Down on Urban and Agricultural Runoff Blamed for Dead Zones - SolveClimate.com
The application of nutrients such as nitrogen to the soil is a large contributor to “dead zones” in water – leading to multiple fish kills each year. The excess nutrients cause algae blooms that deplete oxygen in the water as they die off. This article focuses on nutrient reduction as the Obama administration, Congress, and the EPA usher in “a new era of federal leadership.”
Holistic Management leads the way in the Soil Carbon Challenge - www.savoryinstitute.com Soil carbon is a basic indicator of ecosystem function, water retention, and productivity. The Soil Carbon Coalition uses plot specifications to co-locate permanent plots with the Land EKG transects that Charley Orchard set up and read. Tony and Andrea Malmberg are a great example of experienced ranchers leading the way in the Soil Carbon Challenge
