Low emissions agriculture: Suppor3ng agricultural development that GHG emissions or sequesters carbon.
What it does -‐ Es3mate GHG emissions for different land use systems according to management types;
-‐ Rank the most effec3ve mi3ga3on op3ons; -‐ Es3mate the mi3ga3on poten3al of different op3ons.
What it does not do
-‐ Es3mate life cycle assessment of GHG emissions; -‐ Scale emissions up to total area, total livestock; -‐ Es3mate GHG emissions in different microclimates; -‐ ….
Main objec3ve of CCAFS-‐MOT -‐ User friendly -‐ LiJle ;me required -‐ It widely used -‐ Quick user vs expert user -‐ General overview of key emission sources
-‐ Tool to help providing advice for policy makers
-‐ Accommodates regional differences
GHG emissions: main input variables are flexible
• Region, climate, soil characteris;cs • Ecosystem: upland (34 crops + other), rice, grassland
• Current management prac;ces: user can choose which prac3ces they are using (e.g. fer3liser applica3on rate, 3llage prac3ces).

• Nitrogen Use Efficiency (NUE)= Kg N removed with harvest / Kg of mineral fertilizer N applied * 100.
