ABSTRACT
The chapter focuses on the application of geospatial technologies specially satellite remote sensing data and methods to assess the challenges and threats of Sundarbans originated from natural and man-made sources. Discussions are provided at the outset about the historical mapping activities during the beginning of twentieth century using airborne survey techniques supported by traditional mapping methods. In current times wide range of applications of remote sensing techniques are observed to examine both the health of mangrove ecosystems and also the land use, land cover change and disaster impacts on human population who are living in the forest adjoining areas. The current applications generally pay attention on the interface between man and nature as part of developing better understanding towards mangrove forest conservation and sustainable management. This chapter examined the impacts of Cyclone Amphan on the forest adjoining communities using Sentinel 1 data to understand how human pressure on mangrove forests is linked to sufferings that may cause from disaster impacts. The chapter recommended the use of more advanced remote sensing techniques such as Light Detection and Ranging and rapid image processing facilities using GEE (Google Earth Engine) to generate knowledge about different aspects of the Sundarbans more precisely and almost real-time.
