Proposal approved to build groynes using tetrapods from Valiathura to Shanghumughom as part of efforts to reduce coastal erosion along the southern coast.
The Department of Water Resources has approved a proposal to build seedling beds using tetrapods from Valiathura to Shanghumughom as part of efforts to curb coastal erosion along the southern coast.
The ministry, through an order dated 5 May 2026, approved an estimate of ₹7 crore for the work, which also includes “reformation” of the embankment in the area. The department approved the proposal based on a detailed project report submitted by the Chief Engineer, Irrigation and Administration. This was also one of the projects proposed in the district during the Nava Kerala Sadas organized by the Left Democratic Front government.
The water resources department has directed the chief engineers to fix the deadline for the works and prepare an implementation plan to complete them on time.
In terms of coastal erosion, the Valiathura-Shanghumughom stretch has been listed as one of the worst affected in Thiruvananthapuram district.
Resident demand
Due to the intensity of erosion along vulnerable stretches of coastline, coastal residents are demanding protective measures such as seawalls.
At the same time, studies blame unscientifically built “hard structures” – seawalls, ridges and harbors – for exacerbating coastal erosion. In June 2021, an independent review (Seashore Erosion in Kerala: A Review and Recommendation) by serving and former scientists from the University of Kerala and the National Center for Earth Science Studies recommended that the government adopt “living seashore” models instead. Their advice was based on the conclusion that the existing breakwater and seawall structures only served to exacerbate erosion.
