The state’s 720-km coastline will soon get an eco-friendly way of arresting soil erosion. The state government, in a bid to prevent soil erosion on its coastline, will use geo-textile tubes for arresting silt in the highly eroded areas.
The tubes, which are eco-friendly, will be submerged and placed over sand-filled gunny bags. Over the time, a bay will get created and marine life will grow on the tubes creating a reef like structure over the years.
This will also attract fish.
The Asian Development Bank has agreed to fund up to Rs 480 crore of the Rs 800-project cost, while the state cabinet will take a decision on the remaining funds in the Cabinet meeting on Wednesday.
The proposal to be tabled in the Cabinet suggests that the state will contribute 266 crore through a loan and the rest Rs 80 crore will come from private parties.
Of the 720-km coast, 541 km is protected (either naturally or by coastal agencies), while the rest 319 km faces erosion, of which 72 km has been identified as high-erosion areas.
As a part of the first phase of the project, the state government has identified a 320-m long stretch at the Mirya Bay at the Konkan coast.
The project which will immediately take off after the Cabinet nod will be completed by 2013 and cost Rs 72 crore.
In the second phase the government will be laying tubes at Mirkarwada at Ratnagiri.
“When we were looking at ways to arrest soil erosion, several options like walls, tetrapods were considered, but this is the best option we have come across. It has been successfully implemented in Kerala-Kovalam and Goa,” a state government official said.
