Geography and climate

Kadmat Island, which belongs to thetownshipof Kadmat Island ofAminidiviTehsil.[1]is the central most island of theLakshadweeparchipelago.It is in the shape of a tear drop, with 3.5 square kilometres (1.4 sq mi) area and is located on a coral reef. With a length of 9.3 kilometres (5.8 mi)[a]from north to south and a maximum width of 0.57 kilometres (0.35 mi)[4]and it is the longest island in the Amindivi group.[5] Its southern end is the narrowest with a width of about 10 metres (33 ft). The island's topography is about 2.0 to 3 metres (6 ft 7 in to 9 ft 10 in) on the eastern side and 2.0 to 4 metres (6 ft 7 in to 13 ft 1 in) on the western part above the mean sea level. Its surface formation consists ofcoralconglomerateoverlying broken pieces of coral and coral sand.[6]

Thelagoonon the western side of the island[7]extends over a maximum width of 2 kilometres (1.2 mi)[8]covering an area of 37 square kilometres (14 sq mi)[6]and the water depth is shallow about 2 to 3 metres (6 ft 7 in to 9 ft 10 in).[9][10]It has a shore line and has a sandy beach. The reef width is about 50 metres (160 ft). The tidal range lies between 0.6 to 1.6 metres (2 ft 0 in to 5 ft 3 in).[9][10][11][6]The beach on the eastern side of the island has a width of 100 metres (330 ft). At the breaking zone of this beach there is a 100 metres (330 ft) wide coral algae ridge.[7]

Kadmat Island is bounded byKavaratti Islandto its northwest at a distance of 67 kilometres (42 mi). It is 32 kilometres (20 mi) away fromKiltan Island.Amini Island,which marks the northwestern part of thePitti Bankformation, is 5 kilometres (3.1 mi) to the southwest.[6]Kannuris 292 kilometres (181 mi) away,Kozhikodeis 327 kilometres (203 mi) away andKochiis 407 kilometres (253 mi) away.[12]

There is an airport on nearbyAgatti Island,in which flights operate fromCochin.From Agatti, it is a two and half hours boat ride to Kadmat. Ferry services also operate from Cochin on the coast ofKeralabut involves a journey of 16 hours.[13]

Climate and the environment

The island experiences an average annual temperature in the range of 24.2–34.4 °C (75.6–93.9 °F). Rainfall occurs during the monsoon season from May to September with an average annual rainfall incidence of 1,237 millimetres (48.7 in) as per records of the nearby island of Amini.[14]The maximum rainfall recorded in a day is 241.8 millimetres (9.52 in). Humidity averages at 72.5%.[12]

Ecologically, the island is composed of coral reef withseagrass,andmarine turtleswhich nestle here. Keeping this aspect in view, theMinistry of Environment and Forests (India)has notified the island as a marine protected area to enable conservation of the island's animal, plant, or other type of organism, and other resources.[15]The coral reefs are damaged to the extent of 10% (assessed byIUCNin 1976) due to anthropocentric pressure and also due toclimate change.Dredging operation at the entry to the island is causing damage to coral species as the dredged material is dumped into the lagoon. Coral blocks found in the beaches and the coral flats are extracted for building activity on the island. This could cause serious geo-morphological changes of the island in the form of sea erosion of the shores and the beach. Coral bleaching, a natural phenomenon attributed to strongEl Niños,which occurred during 1998 due to seawater warming, is reported to have reduced the number of coral species from 45 to 9.[16]

Wildlife

[edit]

The island has three types of habitats: coral reef, seagrass and nesting ground for marine turtles.[14]Zoning of the coral reef is mapped under three zones ofreef flat,reef slope and lagoon. Next to the shore line are thefringing reefswhere fish species offinandshell fishesspawn,and are found in abundance. As of 1986, there were 45 coral species in the reef. These are threatened due to human interference and natural causes.[15]Live coral is reported in less than 1% area. There are 9 species of live corals in the lagoon and reef slope area. The species of live corals reported are:Acropora formosa(staghorn coral),Acropora robusta,Acropora,Acropora subglabra,Acropora tortuosa,Acropora vaughani,Favites,Pocillopora verrucosaandLobophytum[25]Benthic organisms are reported on the reef slope and lagoon area. Macrobenthos are found in the inter-tidal and sub-tidal area. 23 species ofpolychaetes,3 species ofbivalves,3 species ofcrustaceans,and 3 species ofgastropodshave been recorded.[26]

The seagrass beds, which forms an area of around 13.8 square kilometres (5.3 sq mi) across the island,[27]provide crucial food forturtlesanddugongs,with four species of marine turtles reported:Chelonia mydas(green sea turtle),Dermochelys coriacea(leatherback sea turtle), andEretmochelys imbricata(Hawksbill sea turtle) andLepidochelys olivacea(Olive Ridley sea turtle).[28]There are 7 species of seagrass reported here, out of 14 found in the Lakshadweep Islands, including theThalassia hemprichiiandCymodocea rotundata.[28]Seaweedsrecorded consist of 34 species, out of which 14 species are ofRhodophyceae,13 (red algae) areChlorophyceae(green algae) and 7 species arePhaeophyceae(brown algae).[29]20 species ofPhytoplanktonand 19 groups ofZooplanktonhave been recorded in the reef slope and lagoon area;[30]33 species of benthic organisms have also been noted in the same vicinity.[26]
