This study was undertaken in the context of the Tsunami of 26 December 2004 which was a grim reminder of the need to ensure the protection of coastal and island ecosystems and its people. The first section of this Study contextualises the impact of the Tsunami by describing the role and function of coastal and marine ecosystems in Tamil Nadu and Pondicherry and the impacts of human activities. Detailed information is provided on ecologically important areas such as the Gulf of Mannar, Pulicat Lake and Vedarnyam. The second section examines Coastal Tourism in Tamil Nadu and Pondicherry and Tourism Plans post Tsunami. The third section lists the loss to human life and property for districts and specific sites. The fourth section examines the implementation of legal and policy framework for coastal conservation and regulation in Tamil Nadu and Pondicherry and the final section offers specific recommendations that emerge from the study.
