ENVIRONMENTAL IMPLICATIONS OF THE SOIL SETTLEMENT IN MUNROE ISLAND, KOLLAM, KERALA, INDIAUdayakumar J., Jesna Fathima, Anamika B. and Athira V.R.
The Munroe island in the Ashtamudi estuary of Kollam district in Kerala is facing the threat of sinking and soil settlement. The main objective of this study is to find out the reasons for the soil settlement in the island. The soil samples were collected from different parts of the island and the organic carbon content in the soil was estimated. An attempt was also made to study the soil breathing in the island. Based on these, the hypothesis that the main reason for soil settling is the near surface oxidation of carbon in the organic soil of the deltaic island was tested and proved correct. The higher concentrations of carbon dioxide emission from the soil were mostly from the locations affected by soil settlement.
