Beach, R. H., DeAngelo, B. J., Rose, S., Li, C., Salas, W., & DelGrosso, S. (2006, January). Mitigation Potential and Costs for Global Agricultural Greenhouse Gas Emissions. Presented at International Association of Agricultural Economists Conference, August 12-18, 2006, Gold Coast, Australia.
Agricultural activities are a substantial contributor to global greenhouse gas (GHG) emissions, accounting for about 58 percent of the world’s anthropogenic non-carbon dioxide GHG emissions and 14 percent of all anthropogenic GHG emissions, and agriculture is often viewed as a potential source of relatively low-cost emissions reductions. We estimate the costs of GHG mitigation for 36 world agricultural regions for the 2000 – 2020 period, taking into account net GHG reductions, yield effects, livestock productivity effects, commodity prices, labor requirements, and capital costs where appropriate. For croplands and rice cultivation we use biophysical, process-based models (DAYCENT and DNDC) to capture the net GHG and yield effects of baseline and mitigation scenarios for different world regions. For the livestock sector we use information from the literature on key mitigation options and apply the mitigation options to emission baselines compiled by EPA.
