Scientists identify critical coastal erosion zones in Goa, report awaited

MARGAO: The National Centre for Sustainable Coastal Management (NCSCM) has completed its study on sand erosion in Goa.

This was confirmed by Environment Minister Aleixo Sequeira who added that the government had not yet received the final report from NCSCM, but would “move forward” accordingly once they get the report.

The NCSCM team, comprising five scientists, had visited Goa last month to conduct a field study along the coastline. Majorda beach was selected as the primary focus area after recent high sea levels had submerged the entire shoreline, prompting the Environment Minister's request for the NCSCM's intervention.

According to Sequeira, NCSCM had already identified certain critical areas along Goa's coast that were experiencing erosion during their previous aerial survey of the region. The Goa visit was intended to study these problem areas in detail and explore potential mitigation strategies.

The NCSCM scientists noted that Goa's coastal belt has been witnessing a mix of both beach accretion and sea erosion. In their initial recommendations, they had emphasised the importance of planting native vegetation as a means to contain the ongoing erosion.

While bio-shields and other structural interventions are often suggested to combat sea erosion, Sequeira has expressed a preference for more eco-friendly solutions. The Minister stated that the government is open to evaluating a range of options, including the NCSCM's recommendations, before making a final decision.

Notably, Sequeira has made it clear that the State is not inclined to adopt tetrapod measures, as they may not align well with Goa's beach tourism industry.

The NCSCM scientists also sought to understand the wave patterns along the Goan coast, particularly whether the waves breaking deep in the sea are encroaching onto the shoreline. They highlighted that the erosion issues have been prevalent since the 1990s and have worsened over the years.
