The analysis resulted in the classification of 31 villages as highly vulnerable that are mostly located over swales and low-lying areas adjacent to creeks. We have estimated the coastal vulnerability for Jagatsinghpur District, Odisha, along the eastern Indian coast using coastal landforms, elevation, creek order, proximity to the creek, proximity to the open coast as the physical variables. The study addresses this gap by developing an approach to assess the vulnerability of a coastal inland as two-dimensional vulnerability maps that captures the physical and demographic variabilities of the inland region. During storm surge, rivers and creeks act as carriers that induce inundation to the low-lying inland areas causing damage to the invaluable coastal livelihood. The coastal vulnerability is often assessed along the shoreline and it fails to capture the inland physical variabilities. The regional analysis of shoreline change along the Odisha coast would not only provide coastal managers with critical information on shoreline dynamics but also draw attention to vulnerable areas linked to shoreline dynamicity along the coast.Īssessment of coastal vulnerability has achieved a recent pace due to the increasing frequency and intensity of tropical cyclones and anticipated sea-level rise. The study identified the hotspots of coastal erosion along delineated study zones by synthesizing data from previous studies as well. In 2050, 55.85 % of the transects are expected to show accretion, while 44.15 % would show erosion or a constant trend. The 1995-2000 period showed an accretion trend, whereas, during the last period, i.e., 2015-2019, the percentage of transects depicting erosion and accretion was almost similar. During the short-term analysis, the 2000-2005 period had the highest percentage of erosion (64.27 %), followed by the 2005-2010 period with an erosional trend of 59.06 %. The long-term shoreline analysis shows that the mean shoreline position is about 0.67 m/year and also highlights that 52.47 % (227.4 km), 34.70 % (150.4 km), and 12.83 % (55.6 km) of the total Odisha coastline exhibit erosion, accretion, and stability, respectively. This study utilized multi-temporal/spectral/spatial resolution satellite images and a digital shoreline analysis (DSAS) tool to appraise the short- (at five/six-year intervals) and long-term (1990-2019) shoreline dynamics along the coastal part of Odisha over the past three decades (1990-2019). The objectives of this study are to assess the short- to long-term shoreline changes of the Odisha coast, to understand how anthropogenic influences, and particularly extreme natural events, affect these changes, and to predict shoreline changes for 2050. The eastern coast of India is one of the regions where most of the population resides in urban areas in the low-elevation coastal zone, making it vulnerable to frequent extreme weather events. ![]()
