Earth observation based multi-scale assessment of logging activities in the Democratic Republic of the Congo

The present study investigates the applicability of a multi-scale approach combining pixel- and object-based images analysis methods for the assessment of different logging activities in the context of conflict in the DRC. Optical high and very high resolution satellite imagery from 2000 to 2014 are analyzed within three different districts characterizing specific logging activities. As a major result one can clearly distinguish these activities and link them to the specific situation in the respective region. In the case of Ituri district logging is directly related to the conflict situation and increasing population pressure. While the slash-and-burn activities in Tshopo seems to be stable and show only minor decrease of primary forest, industrial-scale logging in the Mongala district has degraded a significant amount of primary forest into secondary forest or bare soil.
