| Geo-textile tubes to help restore Goa Candolim beach Posted: 24 Apr 2010 11:39 PM PDT In an attempt to prevent further erosion of the Candolim beach and help restore it, the Water Resources Department of the Goa government has begun laying geo-textile tubes as barricades to prevent waves from directly hitting the shore. Disclosing this to 'The Navhind Times' Mr Pramod Badami, the executive engineer in-charge of anti-sea erosion measures of the WRD, further said that ever since the River Princess, the ill-fated vessel, ran aground way back in the year 2000, the Candolim beach was being eroded by 10-15 metres every year, besides the shore has also been washed away. Concerned over the "massive" erosion and washing away of the shore, the WRD sought the help of Pune-based Central Water and Power Research Station, a wing of the central water commission, to combat the erosion and restore the beach and the shore. Mr Badami further said that between the shore and the River Princess a sand bar has been formed which has been stopping flow of sand (circulation) from one end of the beach between Calangute and Candolim. He disclosed that the central government agency has directed that the sand bar formed between the ship and the beach be opened so that sand movement starts again and the beach is restored properly by change of tidal current pattern. The sand is being removed and placed on the beach and thereafter levelled and this will serve as a nourishment for it. Accordingly, the WRD has taken soft measures wherein geo-textile tubes measuring 20 metres in length and three metres in width are being placed along the beach. These tubes help break the waves and the sand particles get accumulated behind the tubes and help in formation of the beach, he said. Accordingly, heavy machinery is being used to carry out the work. He also said that another layer of tubes, called the scour tubes, has also been placed along the beach and these tubes also facilitate formation of beach. The work has been going on for the past several months and result was almost visible, he said adding that all the government agencies have approved the ongoing work. He went on to add that two rows of tubes have been placed towards landwards covering a distance of 1,100 metres towards Calangute and into sea at a length of 900 metres, following which beach of one and half metre in thickness and 35 metres in width has begun forming in the area.

| Goa State to host meet on turtle conservation Posted: 24 Apr 2010 11:19 AM PDT Around 800 participants from 50 countries across the world are expected to take part in the 30th annual symposium on ‘Sea Turtle Biology and Conservation‘ to be organized by the International Sea Turtle Society in Goa from April 24 to April 30. While the main event will be held from April 27 till April 29, pre-symposium workshops and meetings will be held on other days. ”For the first time, the symposium is coming to the South Asian region, Kartik Shanker president, International Sea Turtle Society said. The symposium is being jointly hosted and organized by sea turtle conservation groups, research organizations and institutions that work on marine environment issues across India and South Asia. ”The ISTS Annual Symposium is truly unique, drawing an enormous number and diversity of people interested in these intriguing animals and their habitats,” Shanker said. Sea turtles live on land and sea, and migrate across the oceans to shores, from cold temperates to warm tropical waters. “They migrate across ocean basins. And through the course of several thousand years, they have connected us ecologically and culturally to the sea,” an activist said. The symposium will attempt to focus on marine and coastal habitats, fisheries and other livelihood-related issues, environmental impacts, and much more, within the context of sea turtle biology and conservation. “The presence of Olive Ridleys, greens and leatherbacks have been reported in Goa. Olive Ridleys are common, but sightings of green turtles and leatherbacks are sporadic,” said a turtle conservationist. “Except for some reports of nesting of leatherbacks along the 2km stretch of Beach at Morjim, all other records have been of Olive Ridley sightings,” the source added. The threats faced by sea turtles everywhere mainly comprise poaching, incidental catches in fishing nets and developmental activity along the coast. ”The killing of adult turtles does not occur very regularly and this has been attributed mainly to religious beliefs. Like in other parts of the country, incidental catches usually occur in trawler nets. Trawl boat owners are either unaware of turtle excluder devices (TEDs) or are disinclined to using them,” one of the participants said. Courtesy: TOI |
