“…Many researchers have tried to explore the geomorphological changes of the Indian Sundarbans. Using the tools of geoinformatics Kundu and Halder [16] attempted to track changes in the shorelines of the Sundarbans for the duration of 1975-2018. Hazra et al [17] tried to understand the geomorphological changes in the Sundarbans caused by the sea level over 10-20 years.…”

The Sundarbans is currently a subject of serious concern due to the massive coastline erosion that is responsible for reshaping the geomorphological content of the islands. The coastal islands of the Sundarbans have become more susceptible to sea-level rise, cyclonic storms, and coastal flooding, which further accelerate the process of coastal erosion. Identification of erosion-prone regions is highly essential for integrated coastal zone management. Till date, no scientific study has been done to relate the coastal erosion accretion process with tidal velocity and current direction in the Indian Sundarbans. In this perspective, the present study identifies the erosion-accretion zones in the Indian Sundarbans using Landsat imageries of 2000 and 2020 using geoinformatics. It investigates the impact of tidal velocity and direction on the erosion accretion processes. MIKE 21 two-dimensional hydrodynamic model was simulated to predict tidal velocities and directions. The study finds that the sea-facing islands of the Indian Sundarbans experience the maximum amount of erosion. A significant shrinking of the land area takes place in the Bulchery, Bhangaduiani, and Dalhousie islands. The rates of erosion of these islands are 485.99 m/year, 487 m/year, and 480.65 m/year, respectively. Places with high velocity are found to be erosion-prone, while the rate of erosion significantly varied with the flow directions. Two islands, Bulchery and Dalhousie, on the south-eastern margin of the delta, suffered maximum erosion over the past decades due to the impact of high-velocity currents from the southeast and southwest, respectively. Alternatively, minor accretions were observed along with the sheltered island precincts where velocities were comparatively low. Such studies on the current drive erosion–accretion processes along the delta margin during sea-level rise appear to be of utmost importance for sustainable coastal protection and management.

Remote sensing (RS) and geographical information system (GIS) have been extensively used for their ability to provide better scope for decision making in terms of monitoring and managing various natural resources: water, land, forest, agriculture, natural hazards, climate change, etc. In this chapter, the authors precisely discuss in detail about the various applications of remote sensing and GIS in numerous fields such as monitoring water quality, crop modelling, monitoring wildlife habitat and forest management, application in agriculture and soil science, water resource, as well as natural disaster management. This chapter will also incorporate several case studies where GIS and remote sensing were used as a powerful tool to delineate and monitor environmental changes and take the necessary steps to manage the same. This chapter will thus focus on the importance of remote sensing and GIS and its impact in sound decision-making, which in turn will secure the sustainable utilization of natural resources to reach the requirements of present as well as future generations.
