"Crop Yields, Food Security, and GHG Emissions: An Analysis of Global Mitigation Options for Rice Cultivation"
by Creason, Jared, Robert Beach, Zekarias Hussein, Shaun Ragnauth, Sara Ohrel, Changsheng Li and william salas

Global agriculture faces the dual challenges of improving food security for a growing population while simultaneously reducing the environmental footprint of agricultural production, including net greenhouse gas (GHG) emissions. Paddy rice production is the 5th largest source of methane emissions, globally.

But the impacts of crop production decisions extend beyond the economic costs and benefits. Fueled by concerns over ethanol, a lively debate has emerged over food security issues (Searchinger, et al 2013). Rice is a staple crop produced in areas with fast-growing populations that have been plagued by food shortages. CH4 mitigation might have an adverse impact on food security.

Extending prior work on GHG mitigation to examine food security implications, we used the GTAP model is to examine domestic consumption and trade flows between 140 countries in the v9 GTAP data set. Food security is assessed using food balance sheet data from the FAO. We find that at carbon prices up to $50 the result on food security is mixed. This analysis provides valuable insights into the potential tradeoffs and synergies between food security and GHG mitigation from rice cultivation in different parts of the world.
