Geospatial technique to study forest cover using ALOS/PALSAR data

Abstract

Forests are one of the most crucial life supporting system that provide range of economic, social and environmental benefits, including essential ecosystem services such as climate change mitigation and adaptation. Forest plays an important role in maintaining ecological balance and homeostatic in the environment (Wulder and Franklin, 2003). Forest cover mapping is necessary for sustainable management and utilization of forest resources. Forest cover monitoring based on geospatial data can significantly contribute in future forest management plans for reducing deforestation and implementation of climate change mitigation policies. Establishing a reliable baseline of forest cover and monitoring forest cover change in the tropical countries become essential (FAO, 2001; REDD, 2010). Recent report of FRA (2010) shows the global change in forest area is about -5.2 million hectares per year during 2001-2010.
