Coastal Vulnerability Index [CVI]

Coastal vulnerability is a geospatial concept that determines the places and people at more risk of coastal hazards. The coastal hazards that can cause damage to the property of a person include sea-level rise, coastal storms, and erosion. Coastal hazards also pose a significant danger to the social system of coastal communities.

Coastal Vulnerability Index [CVI] - Overview

The Indian National Center for Ocean Information Services (INCOIS) established a Coastal Vulnerability Index [CVI] by conducting a coastal vulnerability analysis. This was done by making an atlas comprising 156 maps on a 1:1,00,000 scale at the state level of the Indian coast.

INCOIS collects data on coastal slope, sea-level rise, shoreline change rate, coastal geomorphology, coastal elevation, tidal range, and significant wave height to develop an atlas.

The map helps predict the relative coastal risk due to future sea-level rise of the Indian coast. It depends on the physical and geophysical criteria, and these criteria also help carry out the coastal Multi-Hazard Vulnerability Mapping (MHVM).

Importance of the Coastal Vulnerability Index [CVI]

The Coastal Vulnerability Index [CVI] delivers valuable information for coastal disaster management. It can be used to determine the area with more coastal risks due to rising sea levels and help construct resilient coastal communities.

CVI can help understand the rate of change in coastal areas and help city planners develop coastal hazard resilient designs to prevent the loss of their residences and property.

It is also essential to plan for coastal hazards as India has a total coastline of 7516.6 kilometres, the mainland has an entire coastline of 6100 kilometres, while the rest of the coastline contains Indian islands of 1197 kilometres.

Benefits of the Coastal Vulnerability Index [CVI]?

The benefits of the Coastal Vulnerability Index [CVI] include:

• CVI comprises 28 years of satellite data by the National Center of Coastal Research. The data indicates that 33.6 per cent of the Indian coast is eroding due to the rate of ongoing changes.
• Coastal Vulnerability Index [CVI] provides valuable information for many organisations, such as coastal catastrophe administration and building coastal communities.

What is INCOIS?

INCOIS is an independent organisation under the Ministry of Earth Sciences (MoES). It established the Coastal Vulnerability Index [CVI].

The INCOIS issues alert on topics regarding Ocean State Forecast, Potential Fishing Zone, Storm Surge Early Warning, Tsunami Early Warning, High Wave Alerts, etc. It also provides the finest possible ocean information to society, government agencies, industries, etc.

INCOIS is a division of the Earth System Science Organization (ESSO), located in New Delhi. The ESSO serves as an executive arm of the MoES. It works through customised ocean modelling, observations, marine data centre, and computation facilities.

The significance of the Coastal Vulnerability Index [CVI] lies in its accurate information. MHVM was another component of CVI that derives the composite hazard zones that the government can inundate along with the low-lying coastal areas due to extreme flooding situations.
