University of Illinois researchers has developed a new model that provides a database to estimate location-specific greenhouse gases emissions from agri-food systems.
The model could help identify the primary agri-food sectors contributing to CO2, methane, and nitrous oxide emissions and allow researchers and policymakers to mitigate emissions from major food commodities at different locations across the globe.
The researchers said they hope the study will encourage he development of strategies and public policies that can help mitigate greenhouse gas emissions before climate change becomes irreversible.

GHG Mitigation in Rice Information Kiosk
This website serves as an information kiosk for greenhouse gas emissions and mitigation options in rice production systems. It covers rice management practices, data on biophysical and socioeconomic suitability of farming technologies and practices, and policy actions in Bangladesh, Colombia, and Vietnam.
Crop nutrient management using Nutrient Expert improves yield, increases farmers’ income, and reduces greenhouse gas emissions
Nutrient Expert (NE) tool-based site-specific nutrient management (SSNM) in rice and wheat crops can lower global warming potential by about 2.5% in rice and between 12% and 20% in wheat over farmers’ fertilization practice. More than 80% of the participating farmers increased their crop yield and farm income by applying the NE-based fertilizer recommendation. Adoption of NE-based fertilizer recommendation practice in all rice and wheat acreage in India would translate into 13.92 million tons more rice and wheat production with 1.44 metric tons (Mt) less N fertilizer use, and a reduction in GHG of 5.34 Mt CO2 per year over farmers’ current practice.
Greenhouse gas Mitigation in Irrigated Rice Systems in Asia
The project on Greenhouse gas Mitigation in Irrigated Rice Systems in Asia (MIRSA) seeks to develop an improved water management, based on alternate wetting and drying (AWD), that can always reduce soil-derived CO2-eq emissions (CH4 + N2O) during the rice growing season from irrigated rice paddies, by 30% compared to the conventional practice.
