Coral reef ecosystem - Monitoring and assessment using satellite data sets

Remaining in splendid isolation, the Andaman and Nicobar Islands have a great relevance in the study of marine ecosystems. The islands, though remotely located in an ostensibly pristine environment have born witness to serious issues with regard to their ecosystem health. There are significant changes in the temperature and rain fall pattern in the islands and predictive modelling has forecasted further damage in the near future. The inundation of saline water into inland terrestrial ecosystems has created salinity stress to freshwater species while reducing the water available for domestic consumption. Terrestrial flora and fauna are vulnerable to the intruding saline waters. The marine ecosystem also faces grave challenges. There are issues of anthropogenic pollution resulting in damage of corals, regime shifts in community structure, water quality deterioration and other damage to marine fauna

With increasing evidence that the marine fisheries of India are likely to face major impacts of changing climate along with other natural and anthropogenic factors, a study was carried out to determine the relative vulnerability of 68 species of finfish and shellfish along the Indian coast. Species selection was based on their abundance and importance in the fishery across 4 zones in the country (northeast, northwest, southeast and southwest) and on biological characteristics like growth, reproduction and predator–prey interactions. Vulnerability assessment was based on the relation between exposure, sensitivity and adaptability attributes, expressed as V = (E + S) − A. The exposure attributes selected were environmental parameters that have a direct impact on the fish stocks. Sensitivity attributes were biological characteristics that are indicative of the ability or inability of the species to respond to external pressures. Adaptive capacity attributes were biological and ecological traits that could help the species to adapt to a fluctuating or changing environment. About 69% of the species studied are highly vulnerable along the Indian coast, with their susceptibility being higher along the east coast. Fishing pressure contributes significantly to stock fluctuations and reproductive output. Species with restricted geographic distribution are especially vulnerable to climate change. The outcome of this study will serve as an effective tool in prioritizing mitigation and fishery management strategies on a regional basis in the country.Not Availabl

Assessment of stock vulnerability of Indian marine fishes to past changes in climate and options for adaptation

Carbon Footprint of Marine Fisheries in India

The dynamic nature of India’s marine fisheries and the complexities there in, derived from the diversity of resources, grounds, craft-gear combinations, operation modes and communities involved, make any assessment of its components challenging. More so when global methodologies for such assessments are still in infancy. As a team of researchers engaged for a decade in the estimation of carbon footprint in marine fisheries of India, we feel extremely glad at the outcome of a massive team-effort which paved way for this publication. Accessibility to information, compilation of data sets, analysis and final estimation happened in a coherent manner despite several changes in the constitution of the team during the study. The importance of the marine fisheries sector in India prompted us to generate a baseline data to be compared with the latest changes and technological advancements in fishing operations to prove that our datasets remained scientifically robust for a Pan-India estimation. The financial and conceptual support received from the Indian Council of Agricultural Research-National Innovations in Climate Resilient Agriculture (Marine Fisheries Component) helped us in coming up with this scientific document. The support received from Dr. J.K. Jena, Deputy Director General (Fisheries Science), Dr. S.K. Chaudhari, Deputy Director General (Natural Resource Management), Indian Council of Agricultural Research (ICAR); Dr. V.K. Singh, Director, ICAR-CRIDA; and Dr M. Prabhakar, National Principal Investigator, NICRA, ICAR, CRIDA throughout the study period was instrumental in the completion of this mammoth effort. As the nation looks forward towards ‘net-zero emissions’ as per the agreement of the Conference of the Parties (COP), we as part of the team dealing with climate resilience feel delighted to understand that Indian marine fisheries remain greener, sustainable, and resilient in comparison to our global counterparts. The small-scale nature of the fishery with a large volume of fisher participation moved us in a way that we believe that our realization will be a step forward in recognizing the hard labour of fishers who emit less when their industrial trawling counterparts elsewhere continue to use more fossil fuels. The result of our study on carbon footprint of marine fisheries in India seems like a silver lining for this sector which is otherwise facing serious climate related challenges being in a vulnerable geographical setting. We strongly believe that our policy planners will be able to use this document in evolving fishery management measures to mitigate the challenges posed by climate change
