TECHNICAL SESSION 4: EXTREME ENVIRONMENTS
Interconnecting realms of Biology, Earth Sciences, Chemistry and Physics
Extreme environments on the planet earth have spurred curiosity of countless natural historians and intrepid explorers since time immemorial, including Alexander von Humboldt, Roald Amundsen, Charles Darwin, Alfred Russel Wallace, Earnest Shackleton and so on. Such explorations have resulted in a number of crucial scientific discoveries and overarching theories of basic science; theory of natural selection propounded by Darwin and Wallace being a prime example- a paradigm shift that leveraged advancement of unrelated scientific disciplines. Planet Earth's extreme terrains, such as Antarctica, Arctic, Himalayan glaciers, deserts, ocean trenches, volcanoes, and hydrothermal vents, etc., are important places for curiosity-driven scientific research for many reasons. First, because of its extreme terrain, exploration is exceedingly challenging, and thus such environments remain some of the planet's least explored regions. Because physico-chemical stress is extraordinary, life forms at these locations have developed unique mechanisms to cope with stress— a potential avenue for future bioprospecting efforts, including that for unique biochemical and genetic resources that are responsible for stress tolerance. Moreover, in these extreme environments, life forms provide clues about the very origin of life on our planet, an event that happened ca. four billion years ago. Extremophiles also illuminate the field of exobiology, the search for life throughout the universe. Extremely cold planet earth environments, including montane ecosystems, tundra biomes, polar ice caps and high-altitude glaciers, are some of the most affected places on planet earth due to global warming, and research on such environments plays a key role in documenting and mitigating climate change.
Despite its crucial importance, the exploration and research efforts on planet Earth's extreme environments were rather minimal in India, which is a major yet often overlooked challenge currently facing Indian Science. The Antarctic program of India began in 1980, while the Arctic program began in 2008. Several Indian scientists have made outstanding contributions to research at extreme environments, including Padma Bhushan awardee Syed Zahoor Quasim, Bhatnagar Awardees Hassan Nasseim Siddiquie, N Balakrishnan Nair, Kolluru Sree Krishna, Prem Chand Pandey, Satish Ramnath Shetye, P. N. Vinayachandran, Shankar Doraiswamy and so on.
Proposed in this unique networking session, some of the outstanding scientists involved in transdisciplinary research on extreme environments, including those from biology, chemistry, physics, and earth sciences, are brought together. Dialogs between promising young researchers and internationally renowned intellects from contrasting disciplines will be fostered across domains. As part of this session, conceptualization of white paper with reference to the future of research on neglected extreme environments that have ramifications during the framing of future national scientific policies will be formulated.
