Cost-effective cropland mitigation

Project description

Cereal production significantly contributes to global food security and environmental impacts, particularly through N2O emission. Opportunities exist to significantly reduce N2O emission from cereal production systems by improving nutrient management. This project proposes to scale out cost-effective mitigation measures for cereals in areas that have been identified as emission hotspots with significant mitigation potential. It is developing a methodology for measurement, reporting & verification (MRV) of savings that can be applied beyond the study locations. 

The effort of this project builds on the Improving estimation of nitrous oxide emissions from agriculture project, which ended in 2018. 


  • Delivering GHG mitigation at scale in cereal crops that will promote effective mechanisms to reduce N2O emissions in selected countries where large mitigation wins are feasible. We propose to scale-up and -out precision nutrient management (PNM), acid soil amendment and use of biofertilizers through government & private sector extension programs for cereal crops in India and Mexico.
  • Methodologies for MRV of GHG saving through precision nutrient management and cessation of crop residue burning. 

Expected outcomes

  • Global donors and agricultural development organizations informed of options to support LED and agricultural climate readiness
  • Technical and policy guidance to focus countries, supply chains and donors for LED priorities, with emphasis on livestock systems
  • Methods for MRV of agricultural emission reductions developed with focal countries and donors

Gender and youth

Women are key players in the agriculture sector in developing countries. The project gathers sex-disaggregated data for activities undertaken and cost-benefit analysis across national, sub-national and sectoral levels. Women have been found to be more vulnerable to the effects of residue burning and other agricultural emissions, which if reduced can substantially impact the gender productivity scenario. This project aims to raise the capacity of women and youth on precision nutrient management which will promote gender-equitable N use efficiency which will eventually ensure gender and social equity co-benefits at local scales.


This project is led by International Maize and Wheat Improvement Center (CIMMYT), in collaboration with:

  • Chinese Academy of Agricultural Sciences (CAAS)
  • Indian Council of Agricultural Research (ICAR)
  • International Plant Nutrition Institute (IPNI)
  • Kellogg
