New Delhi: In a surprising revelation, the length of India’s coastline has significantly increased from 7,516 km in 1970 to 11,098 km in 2023-24, marking a staggering 48% rise over 53 years. This dramatic change has been attributed to advancements in measurement methods and the inclusion of coastal features such as bays and inlets that were previously excluded.
Gujarat Takes the Lead
The state of Gujarat has recorded the highest increase in coastline length. Previously measured at 1,214 km, Gujarat’s coastline now spans 2,340 km, nearly doubling in length. The state’s unique geographical features, particularly its numerous bays and jagged shoreline, have contributed to this remarkable increase.
Other States See Changes
- West Bengal: The coastline has increased from 157 km to 721 km, registering a significant rise.
- Tamil Nadu: The length of its coastline has grown from 906 km to 1,068 km, placing it second among Indian states.
- Andhra Pradesh: With a coastline now spanning 1,053 km, Andhra Pradesh ranks just behind Tamil Nadu.
- Kerala: The state has also seen a rise in its coastline length, reflecting the broader national trend.
Meanwhile, Pondicherry has recorded a rare decrease in its coastline length, shrinking by 10.4% due to adjustments in measurement methods.
Why the Coastline Increased
The increase in India’s coastline length is not due to geographical changes but stems from modernized measurement techniques. Previously, only straight segments of the shore were measured. The new methods, which follow global hydrographic standards, now include bays, estuaries, and inland water formations, providing a more accurate representation of the coastline.
Implications for Gujarat and Other States
The revised coastline length has significant implications, particularly for Gujarat:
- Economic Opportunities: With an extended coastline, Gujarat can expand its port infrastructure and enhance its maritime trade potential.
- New Ports: Plans are already underway to construct new ports in Gujarat, further bolstering its position as a maritime hub.
- Tourism and Fisheries: The state’s tourism and fisheries sectors are expected to benefit from this development.
India’s Marine Spread
India’s coastline now stretches across three major marine zones:
- The Arabian Sea (to the west)
- The Indian Ocean (to the south)
- The Bay of Bengal (to the east)
Conclusion
The updated coastline measurement underscores India’s growing focus on aligning with international standards. While rising sea levels are a concern globally, this re-measurement highlights the importance of accurate data for strategic planning, infrastructure development, and environmental conservation.
Gujarat’s expanding coastline reaffirms its status as a key player in India’s maritime landscape, paving the way for enhanced economic opportunities and regional development.
