In addition, the Sundarbans Mangal is situated in the lower Ganga delta which is in a dynamic conditions with large range of variance in terms of physico-chemical properties of soil and water chemistry, which have diverse impact on the total ecosystem. At this juncture, it would be very inappropriate not to mention about the rural society inhaviting Sundarbans. Majority of this population lives in abject poverty and are constantly creating direct and indirect pressure on this threatened ecosystem. This makes Sundarbans a study area for botanists, zoologists, ecologists, environmentalists, anthropologists, economists and social scientists. Moreover, it is of utmost importance to save this unique ecosystem with a multi-discrplinary holistic approach. This book has attempted to undertake an integrated approach towards compilation of existing works of people working on this vulnerable ecosystem. The chapters include topics related to Botany, Zoology, Fish, Fishing, Fishery, Soil, Geology, Geomorphology, Pollution and Socioeconomics. There are 73 articles of different authors from different Institutes working on the Sundarbans Mangal. Besides this, the book also highlights the present problems, pros and cons of the existing scenario of Sundarbans and the suggestions for conservation and development with sustainable approach.
