The document describes CCAFS-MOT, a decision support tool for estimating greenhouse gas emissions from different land use systems and agricultural management practices. It estimates emissions based on empirical models using variables like climate, soil characteristics, ecosystems, and management practices. The tool also ranks the effectiveness of different mitigation options and estimates their mitigation potential. It is intended to be user-friendly and provide quick overviews and advice to policymakers.

it
does
-­‐ Es3mate

of
