Aquatic Salinization and Mangrove Species in a Changing Climate : Impact in the Indian Sundarbans

This paper contributes to understanding the physical and economic effects of salinity diffusion and planning for appropriate adaptation for managing the Sundarbans in a changing climate, with a focus on the West Bengal portion of the tidal-wetland...
