This field trip to the Sundarbans Biosphere Reserve, the world’s largest mangrove ecosystem, will showcase the mangrove communities' response to past climate fluctuations and sea-level changes. The Sundarbans, a UNESCO World Heritage site, offers a dynamic setting to explore long-term ecosystem responses to environmental stressors. Participants will investigate Holocene sea-level changes, salinity variations, and mangrove succession patterns, enhancing our understanding of coastal resilience, carbon sequestration, and ecosystem transformation under changing climates. The excursion also provides a unique opportunity to assess human-mangrove interactions and their imprint on the landscape.
