ABC-Map was designed with the specific objective of holistically assessing the environmental impacts of national policies, plans and investments in the agriculture, forestry and other land use (AFOLU) sector through Google Earth-based satellite imagery. ABC-Map helps to develop synergies and trade-offs between climate, biodiversity and land restoration actions. The overall objective of this technical manual is to provide users with (i) the detailed structure of ABC-Map, (ii) its methodological background, and (iii) the different data and factors used such as emission factors and default carbon stock values, reference values from ESVD, GLOBIO, climate and geophysical datasets among others.
