Sea wall built in Udupi district of Karnataka
Monsoon is definitely on the faces of the countrymen Smile brings, but in Karnataka sea shores But for the people living here, it is no less than a disaster. Monsoon the winds The waves coming here with are eating the shores. The biggest problem is in the Batpadi area, where the sea has swallowed about 100 meters of land here in five years.
Research has been done in Mangalore University on the erosion caused by the sea in Karnataka. Head of Marine Geology Department, Prof. According to KS Jayappa, 30 to 40 percent of the 300 km coastline is getting sea erosion here. Especially the Batipadi area is becoming the new center of sea-land conflict.
30 years old cause
Sea waves have now become destructive in Batipadi area, but earlier this was not the case here. The reason for this is told that Mangaluru port is 30 km away from here. It is said that about 30 years ago boat sinking was common here. After this, dams were made from sandbags and rocks. Due to this, the waves of the sea decreased here, but due to this erosion increased in the opposite direction i.e. Batipada and the nearby coasts.

The problem of erosion does not end with the sea wall
In 2018, a sea wall was built here to protect the coast, so that when the waves break and hit the coast, the effect is not much. In a conversation with DW, marine geologist KS Jayappa said that building a sea wall does not solve the problem, but increases it. Instead of slowing down, the waves change their course and make their prey on the other side of the shores. He says that if a green wall is made in place of the sea wall, then perhaps the erosion caused by the sea can be stopped.
what is green wall
Geologist, Mangaluru University Prof. According to Jayappa, the beach is like a playground for the waves. That’s why we need to step back, if we want to stop them then we have to build a green wall. That is, Casuarina tree or Ipomoea biloba. This can prevent erosion from the sea.
Highest erosion in Odisha
Odisha is one of the states with the highest erosion on the sea coast, according to a report, 50% of the sea erosion in this east coast state is taking place on the coasts. After this Andhra Pradesh is the number, where 48 percent erosion takes place, in Karnataka at present this figure is 26 percent, but it is continuously increasing.
