Gerald Tan (7) Secondary 3D 27 July 2010 Raffles Academy: Geography - Essay (Coastal Protection)
Q1. Examine the success of coastal protection measures in Singapore. Singapore, as a small island nation, has been experiencing continued coastal erosion for the longest time ever. As such, some coastal protection measures have been undertaken to ensure that land-scarce Singapore does not lose anymore of its precious land, which it needs to combat the burgeoning population as well as for various industries for economical growth, not to mention for recreational activities that Singaporeans caught up in the rat race desperately need. In my essay today, I shall be examining the success of coastal protection measures in Singapore. Let us now look at different areas of Singapore where coastal protection measures have been implemented and to what degree of success. Firstly, on the island of Pulau Tekong, the largest of Singapore's outlying islands and used exclusively for army training, more than 1,000 mangrove trees on its north-eastern coastline are at risk of falling due to coastal erosion. Deputy director of National Parks' National Biodiversity Centre, Dr Lena Chan, has said that the erosion, with mud being scraped out, is due to movements of ships and strong waves in the area. The erosion has affected 3km of north-eastern shore, posing a threat to the 92 hectares of mangroves in Pulau Tekong which is one of the largest remaining mangrove areas in Singapore with a mature and undisturbed habitat. At some points, the extent of the erosion was as deep as 1.2 metres below the level of the mangrove berm. The first stage in the restoration process will be to fill the eroded parts below the mangrove berm with mud-filled biodegradable sacks. Next, loosely-placed stones will be placed in front of the berm as a shoreline stablisation measure. Around 8,000 mangrove saplings will be...
