L-15 Detection of Tree Cutting in the Rangelands of NE Somalia
This report outlines how very high resolution satellite imagery was used to estimate the rate of tree-cutting in Puntland. The study used visual interpretation of Ikonos and Quickbird images for 2001 and 2006 respectively to generate tree density maps for the two years. Through collaboration between SWALIM and the EC Joint Research Centre at Ispra, Italy, an automatic procedure for identifying and classifying trees was also tested. Both techniques produced similar results, which showed an overall decrease in tree density between 2001 and 2006. The results also showed some areas where the tree densities have increased due to environmental conservation through community interventions. The method used can be up-scaled to other parts of Somalia to support afforestation campaigns and environmental conservation.
