Answer: Lakshadweep
Notes: R M Hidayathulla, who is from Androth in Lakshadweep, in his research work stated that biodiversity-rich uninhabited ‘Parali I island’ of Lakshadweep has been eroded to an extent of 100% due to coastal erosion. The study stated that the complete erosion and inundation of Parali I was pointing to the gravity of issues associated with coastal erosion within the atoll. Apart from Parali I, net erosion was higher in Parali II (80%), followed by Thinnakara (14.38%), Parali III (11.42%) and Bangaram (9.968%). Hidayathulla was awarded a doctoral degree in July 2017 by Calicut University in Kerala for his work entitled “Studies on coastal erosion in selected uninhabited islands of Lakshadweep archipelago Archipelago with Special Reference to Biodiversity Conservation." He conducted studies on the biodiversity of five uninhabited islands — Bangaram, Thinnakara, Parali I, II and III, of which Parali I has been inundated.
