A time-series analysis study on the eroding shorelines from 1973-2021 shows that erosion is dominant in nearly 39.12% of the entire coastal length inKerala. The eroding length is highest in theNorthernregion at 44.04 percent followed by 38.67 per cent in the central and 33.8 percent in the south.
The study by researchers at the department of Resources“>Water Resources engineering,NIT Karnatakaled by MMParvathyand officials of the state Irrigation department, points out that unlike pre-2000, the results indicate that the past two decades have undergone a drastic transformation, which can be attributed to anthropogenic interventions and global climatic changes.
The coastal protection strategies adopted by the state can be observed to be the main conducive reason for the reduction in the eroding length and the subsequent increase in the stable coast. Seawalls have succeeded to an extent in limiting erosion by forming the boundary line.
