dc.description.abstractMangroves are halophytes that are usually found in the inter-tidal regions in tropical and subtropical regions. Lush green and prominent patches of mangroves are found in Goa, especially in the Mandovi-Zuari-Cumbarjua estuarine complex. The present study aims to assess the shoreline changes along the selected estuaries of Goa and to study the landward migration of mangroves. OBIA Segmentation techniques have been implemented to map mangrove ecosystems over 20 years. From the spatio-temporal analysis (2002-2022), landward migration of mangroves has been observed in the selected estuaries-Mandovi and Zuari including Cumbarjua canal. To further understand the landward migration of mangroves, shoreline analysis has been carried out using DSAS tool. DSAS analysis has been carried out with respect to EPR as it is easy for computation and requires shorelines of two time periods for analysis. From shoreline analysis, it has been understood that the accretion rate is dominant over the erosion rate. Overall, it has been observed that there is accretion and landward migration of mangroves, which can be attributed to the landward shift of mangroves irrespective of rise in sea level if there is availability of adequate sediment and landward space. Also availability of sediments resulting from heavy rainfall and runoff leads to sedimentation and allows growth of mangroves.
