Land owners seeking conversion of wet lands ((cultivable agricultural land with irrigation sources)) for non-agricultural purposes have to get permission through District Collector, where district collectors will have to personally visit the spot and verify that the land for which conversion is sought is no longer suitable for agriculture and collectors were permitted to clear such conversion in case water availability for irrigation had dried up in the area owing to infrastructure growth in catchment areas of water tanks and lakes. Hereafter, Regulatory agencies like the Chennai Metropolitan Development Authority and the Directorate of Town and Country Planning would then take a decision to reclassify the land based on the collector's report. This holds good even for major industrial projects.
