Mangroves are basically salt tolerant forest ecosystems found mainly in tropical and sub-tropical inter-tidal regions. Till about 1960s, mangroves were largely viewed as "economically unproductive areas" and were therefore destroyed for reclaiming land for various economic and commercial activities. Gradually, with the passage of time, the economic and ecological benefits of mangroves have become visible and their importance is now well appreciated. Today, mangroves are observed in about 30 countries in tropical subtropical regions covering an area of about 99 300 km2.
However, during the past 50 years, over 50% of the mangrove cover has been lost, mainly because of the increased pressure of human activities like shrimp farming and agriculture, forestry, salt extraction, urban development, tourist development and infrastructure. Also, dam on rivers, contamination of sea waters caused by heavy metals, oil spills, pesticides and other products etc. have been found to be responsible for the decline of mangroves. Although the temperature effect on growth and species diversity is not known, sea-level rise may pose a serious threat to these ecosystems
Sensitivity of Mangrove Ecosystem to Changing Climate addresses all these important issues in separate chapters with some interesting case studies whose data may serve as pathfinder for future researches in the sphere of the influence of climate change on mangrove ecosystem. The role of mangroves in the sector of bioremediation is a unique feather in the crown of this coastal and brackishwater vegetation that may be taken up by the coastal industries in order to maintain the health of ambient environment.
Sensitivity of Mangrove Ecosystem to Changing Climate seeks to discover and to assess the vulnerability of climate change on mangrove flora and fauna, their role in carbon sequestration and some interesting case studies by some groups of dedicated researchers that may serve as the basis of future climate related policies.

Dr. Abhijit Mitra, Associate Professor and former Head, Dept. of Marine Science, University of Calcutta (INDIA) has been active in the sphere of Oceanography since 1985. He is now the Adjunct Professor of TECHNO INDIA UNIVERSITY, Salt Lake Campus, Kolkata. He obtained his Ph.D as NET qualified scholar in 1994. Since then he joined Calcutta Port Trust, WWF (World Wide Fund), and Ministry of Environment & Forests, Govt. of India in various capacities to carry out research programmes on environmental science, biodiversity conservation, climate change and carbon sequestration. He has to his credit about 228 scientific publications in various National and International journals, and 20 books of postgraduate standards. Dr. Mitra is presently the member of several committees like PACON International, IUCN, SIOS etc. and has successfully completed about 15 projects on biodiversity loss in fishery sector, coastal pollution, alternative livelihood, climate change and carbon sequestration. Dr. Mitra also visited as faculty member and invited speakers in several foreign Universities of Singapore, Kenya and USA. Presently his domain of expertise includes environmental science, mangrove ecology, sustainable aquaculture, climate change and carbon sequestration. Dr. Mitra successfully supervised 17 Ph.D scholars in the branches like Marine Science, Chemistry, Environmental Science and Zoology.
