Understanding agricultural drivers of deforestation through remote sensing: opportunities and limitations in sub-Saharan Africa

Published in December 2016, this working paper from the International Institute for Environment and Development identifies 14 of the most commonly used land cover data products, summarise their spatial, temporal and thematic properties, and compare their estimates of forest and cropland area. It describes the limitations to land cover data that result from their divergent predictions and discuss the implications for using this data to assess the agricultural drivers of deforestation in Africa. Effective monitoring of deforestation and cropland expansion in Africa requires reliable estimates of land cover area. However, continental scale land cover datasets generated solely or partially through remote sensing technologies show large differences in the extent and spatial distribution of forest and cropland.
