India’s vast coastline is increasingly being seen as one of the most vulnerable zones in the face of climate change. Rising sea levels, stronger cyclones, coastal erosion and changing weather patterns are putting pressure on millions of people living in coastal regions. Experts warn that several parts of the coastline could face serious ecological and economic challenges if mitigation efforts are not strengthened.


India’s Coastline Under Threat as Climate Crisis Intensifies Along Coastal Belt

The coastline of India has increased by 3,582 km, or nearly 48 per cent after accurate measurements without any acquisition of territory. In addition, the country's islands have also increased slightly following the reassessment without changing the ground situation.In the 1970s, the length of the coastline was measured at 7,516 km. But, following the assessment, it is now measured to be 11,098 km. The previous measurement was based on data that were of the scale of 1:4,500,000 or smaller. Later, with the passage of time, enhanced and accurate resolution data became available, calculating the length of the coastline using data that had a scale of 1:250,000, as per the Indian Express report.Coastlines are naturally uneven and complex, but when data resolution improves, it’s like switching from a larger measuring stick to a smaller one. For instance, a one-kilometer ruler would overlook minor variations in the land’s shape that a one-meter ruler would easily detect.With higher resolution, we can map the coastline’s curves and indentations in much finer detail. Lower-resolution data tends to smooth out these features, making jagged coastlines appear more linear, which results in a shorter total length.<h3>Can coastline be measured precisely?</h3>Previously, coastline measurements were done using traditional, manual techniques. Now, advanced GIS software allows for much more precise mapping of terrain irregularities. Another factor behind the increased length is the inclusion of coastal stretches of offshore islands that earlier calculations missed. These islands were often too small to show up in low-resolution maps or were excluded due to the limitations of manual measurement processes.Although the newly revised measurement of India’s coastline is more accurate than before, it still doesn’t reflect the coastline’s true length. In reality, the exact length of India’s, or any, coastline cannot be precisely measured. This is due to what’s known as the coastline paradox.Natural formations like coastlines are extremely irregular and don’t have a fixed length. The measured length depends entirely on the resolution used. The finer the measurement scale, the more details are captured, and the longer the coastline appears.This paradox also applies to other natural features like mountain chains and river systems. Rivers, for instance, flow in winding, unpredictable paths, and their banks are rarely straight.Trying to measure the length of a river by tracing its banks runs into the same issue as measuring a coastline. However, river lengths are typically measured along the main course rather than the edges, which avoids this complication. &nbsp;

With higher resolution, the coastline’s curves and indentations can be measured in much finer detail. Lower-resolution data tends to smooth out these features, making jagged coastlines appear more linear, which results in a shorter total length.

India’s coastline just got longer, ‘added’ more than 3,500 km —Know how it acquired

Just days after causing havoc in Port Phillip Bay in Australia on Friday last week, an elephant seal reappeared on a Mornington Peninsula beach. A regional operations manager with Victoria’s Conservation Regulator, Gleen Sharp said that he helped coax the massive seal away from danger last week.&nbsp;

He said, “I was handed an oar, and was trying to get it back to the beach and into the water.”

It was a “large, large animal.” He said that despite being 500 kg the animal was pretty quick, Guardian reported.&nbsp;

The seal’s rescue effort on Friday began after the Police and Parks Victoria responders blocked the traffic to give the aquatic animal space to make its way back to sea. But the seal then turned around and went up into a&nbsp;local service station.&nbsp;

The officials suspect the reason for the seal going down the road in Port Lonsdale was that it was being harassed. The officials also reported that they heard dogs barking at the seal and Sharp also said that the&nbsp;people&nbsp;were getting too close and were taking selfies.&nbsp;

“We believe it was trying to retreat somewhere to safety.”

Sharp added that at the service station, the seal saw its reflection on the glass and defended itself. “That meant breaking the glass.” “Unfortunately, it did probably sustain a couple of cuts.”

Similar instances occurred on Saturday at Blairgowrie, Victoria’s Mornington Peninsula, and a similar appearing seal popped up.&nbsp;

Sharp explaining the occurrence said that “it is unfortunate...because it is pretty popular there.”

He also said that the worst thing people can do is jeopardise their return home. He strongly discouraged people from feeding the seal. “The last thing we want is to make it reliant upon human interaction.”

Giant elephant seal weighing 500kg reappears along Victoria's coastline

Seaweed farming is helping economically empower women living on Kenya's coastlines. Due to overfishing male fishermen's incomes are decreasing meanwhile this new activity is providing a new source of household income.

Under a plan announced by the Biden administration on Wednesday, seven major offshore wind farms would be developed on the east and west coasts and in the Gulf of Mexico. This project comes as a part of Biden’s plan to deploy 30 gigawatts of offshore wind energy by 2030. This will further help in generating enough electricity to power more than 10 million homes.

If the target is met, it could mean jobs for more than 44,000 workers and 33,000 others in related employment, the White House said.

Deb Haaland, the interior secretary said that her department hoped to hold lease sales by 2025 off the coasts of Maine, New York and the mid-Atlantic, Carolinas, California, Oregon and the Gulf of Mexico.&nbsp;

The officials said that the projects could avoid about 78m metric tons of carbon dioxide emissions.&nbsp;

Apart from this, the interior department is also working with other federal agencies to increase renewable energy production on public lands, with a goal of at least 25 gigawatts of onshore renewable energy from wind and solar power by 2025.

Haaland and Amanda Lefton, director of department’s Bureau of Ocean Energy Management have said that the officials hoped to reduce potential conflicts with fishing groups and other ocean users. Lefton in a statement said, “This means we will engage early and often with all stakeholders prior to identifying any new wind energy areas."
