Impact of Agricultural Productivity Gains on Greenhouse Gas Emissions: A Global Analysis
2013
Jones, Carol A. | Sands, Ronald D.
Agriculture is a greenhouse gas (GHG)–intensive activity; whereas it represents 3.2% of global value-added gross domestic product (GDP), it generates between one-quarter and one-third of global GHG emissions from on-farm activities and land use change to cropland. As demand for agricultural commodities increases with population and income over the next decades, actions to mitigate agricultural GHG emissions can make significant contributions to international goals to reduce future global emissions. Here, we use a new, dynamic, global computable general equilibrium model developed at Economic Research Service (future agricultural resources model [FARM]) to simulate the global market impacts of projected crop and livestock productivity changes on the scale and composition of agricultural output across 15 global regions (which we aggregate to 6 in our reporting) and the resulting implications for GHG emissions.
