Innovations in food production and land use that are ready to be scaled-up today could reduce greenhouse gas emissions equivalent to roughly 25% of global fossil fuel emissions and present the best opportunity to remove greenhouse gases already in the atmosphere, according to a new report by the Worldwatch Institute and Ecoagriculture Partners.

As the price of carbon rises with new caps on emissions and expanding markets for carbon offsets, the contribution of land-based, or "terrestrial," carbon to climate change mitigation efforts could increase even further.

Carbon capture and sequestration technologies, which remain unproven and will not be ready for implementation for a decade at best, promise only to sequester greenhouse gases that have yet to be released into the atmosphere. Agricultural and other land use management practices, in contrast, are the only innovations available today to sequester greenhouse gases that are already in the atmosphere-pulling in carbon dioxide through photosynthesis to grow and sustain more plants.
