Lakshadweep Islands are small islands located in South Arabian Sea. It consists 36 Islands, islets, reefs and sand banks with area of 32 sq.km. Eleven of these islands are inhabited. The area of these islands varies from 1sq.km (Bitra Island) to 4.8sq.km (Androth Island). There are fifteen uninhabited Islets . All these islands and Islets have plenty of coconut palms. Maximum height of the Island from MSL is less than 7 M. Lakshadweep islands will be worst affected by climate change. United Nations and associated organizations had developed many programs and projects for sustainable development of small island developing states (SIDS) after earth submit at Rio during 1992. The theme of the present project "Climate Change Adaptation, Research, Capacity building and knowledge building (CARK)" is the global agenda proposed in the SAMOA (Small Developing States Accelerated Modalities of Action ) pathway of the year 2014 and the SIDS meeting held during the year 2015 for agenda 2030 the periodical implementation of the same.
The proposed problem consists two components I. assessment for vulnerability , II. Adaptation for resilience. Assessment for vulnerability consists (1) regional climatic change prediction through reliable regional models (2) the vertical land movement of the Islands and sea level changes through GNSS and InSAR (3) Continuous Plankton Recorder (CPR) Survey of bio-geographic migration of planktons and pelagic fishery resources like tuna resources in Lakshadweep Sea. (4) Monitoring of ground water so as restrain the saline water aquifer below a depth of 1.5 M ie below the level of the roots of the coconut palm. (5) Geospatial survey and house hold survey for socio economic and environmental data including traditional knowhow and technology.
The climate change adaptation for resilience are (1) solar still for potable water. This will regulate the utility of available fresh water aquifer lens and protect fresh water aquifer from further contamination by saline water intrusion (2) Household wastewater treatment plant. The sewage water will be fully treated before discharging into lagoon, sea and ground water aquifer. Due to highly porous coral derbies all the discharged water will penetrate to the aquifer and will vitiate the available fresh water aquifer and the lagoon. Appropriate treatment of waste water will protect the freshwater aquifer and lagoon. (3) Compact anaerobic digester will be installed at each house so as to convert kitchen waste into biogas. This will protect the Island environment and will supply clean energy. (4) Installation of coir retting equipment on community basis to eliminate the environmental deterioration and greenhouse gases generation to environment due to retting process. (5) Climate change adaptation and sustainable development. Climate change adaptation with improved appropriate technology is an essential requirement for the livelihood security of Lakshadweep people. Geospatial Technology (GST) and Information and Communication technology (ICT) are the most appropriate technologies for proper adaptation and mitigation.
