摘要

Forest is one of the most important renewable natural resources and plays a significant role in the human life and environment. In recent years, prolonged dry weather together with rapidly expanding exploitation of tropical forests and the demand for conversion of forest to other land uses have resulted in significant increase in forest fire size, frequency and related environmental impacts. Recurrent fires decrease the green cover by preventing regeneration and lead to the slow death of the forest1. The frequency of fires in Indian forests today is far greater than at any time in the past. Human influence has now become so pervasive that most fires are ‘unnatural’ like in arid and semi-arid regions of India. There is a need to focus on studies related to monitoring and management of forest fires of Indian forests. In this regard, use of satellite remote sensing in view of its synoptic view and temporal frequency is realized as one of the potential tools in identification of burnt areas and potential fire zones. Few studies have been conducted in India to know burnt forest area assessment using high-resolution data from IRS satellites. Currently, several satellite-based sensors like LISS-III, AWiFS, MODIS, OCM, WIFS, AVHRR and MODIS provide synergistic data sets that have potential in forest detection and monitoring.
