Since the inception of the concept, sustainability has been interpreted as encompassing social, economic, and environmental dimensions of it. It is now rapidly shifting from a concept to a measurable state of the human-ecological dynamic system. Recent research is focusing on an integrated approach, due to the absence of a perfectly defined sustainable condition with the presence of some driving forces in the environmental system as a reference. In the recent world, severe natural hazards are increasingly having a fatal impact on societal and economic strata. The islands of Indian Sundarban Delta are the focus of this study as their sustenance is highly at stake due to climate change induced sea level rise, cyclone, tidal surge, and severe land erosion. The main objective of this study is to design a model for obtaining a composite sustainability index of three adjacent islands of western part of Indian Sundarban Delta (ISD) Sagar, Mousani and Ghoramara which are facing severe hazard impact based on the ‘Driving Force-Pressure-State-Impact-Response’ (DPSIR) framework integrating all three dimensions. Indicators have been categorised into state indicators and driving forces under ten profiles chosen from three dimensions of sustainability. The impact score of driving forces over any profile has been considered as a product of values of drivers and states from that profile. The total sustainability score was attained by summarizing the impact scores assigning the same weights and different weights respectively, to the sustainability indicators. The sustainability score shows that Sagar is in a better position than the other two islands. |
