CLIMATE CHANGE AND VULNERABILITY OF COASTAL VILLAGES IN TAMIL NADU Be Smart!Be Aware!!Be Climate Smart!!!ICAR-CENTRAL MARINE FISHERIES RESEARCH INSTITUTEwww.cmfri.org.inNATIONAL INNOVATIONS ON CLIMATE RESILENT AGRICULTUREWeather -Climate -Climate change –Global warming - daily condition of the atmosphere in terms of temperature, atmospheric pressure, wind and moisture. prevailing weather conditions in, and typical to, an area over long periods of time.  long-term change in the normal weather pattern which includes change in temperature, precipitation and wind pattern among other things. gradual increase of earth’s average surface temperature due to emission of green house gases such as carbon dioxideClimate change is mainly the effect of human activities such as burning of fossil fuels, land conversion, deforestation, infrastructure development, industrial processes and from agriculture processes.Vulnerable areas of Cuddalore and Kancheepuram districtMajor causes of vulnerabilityChennai research centre of CMFRI conducted vulnerable studies in 10 villages each in Cuddalore and Kancheepuram coastal districts by using 5 different indicators namely, environment, fishery, economic, social and development drivers and 119 attributes.Fishers were asked to rank between 1-5 indicating the severity of the vulnerability; 5 indicates very high and 1 is negligible.     Major cyclone and floods due to global warming in Tamil NaduMitigation and Adaptation options Ø Construction of sea walls Ø Identify new fishing grounds based on PFZ information of INCOISØ Changing craft and gear combinations Ø Promoting artisanal and traditional eco-friendly fishingØ Reducing fuel usage to reduce GHG emissionsØ Preparedness based on climatic eventsØ Strictly following Government regulationsØ Identifying new alternate livelihood options like open sea cage farmingØ Participatory fishery resource and habitat managementØ Help in awareness generation in neighbouring villagesHIGHLY VULNERABLE VILLAGESPettodai, Reddiarpettai and Sothikuppam Pudhupattinam, Palaya Nadu Kuppamand Sulerikattukuppam Cuddalore: Kancheepuram: Vulnerable villages of Cuddalore and Kancheepuram districts Coastal district  Environment  Fishery  Social  Economic  DevelopmentDriversKancheepuram  Pudupattinam  (Extreme weather events)  Suleri kattu  kuppam  (Decrease in catch)  Kadulur Chinna kuppam  (Infrastructure sensitivity)  Kovalam  (Increased cost of fishing  Mamallapuram (Anthropogenic activities)Cuddalore  Pettodai  (Habitat destruction)  Thammanam pettai (Change in species composition)Sothikuppam  (Lack of social participation)  Reddiarpettai  (Increase in cost of fishing)Sothikuppam(Infrastructure drivers)Name  Month and year  Place  Causes  ImpactVardah  (Mini Tsunami)  12th December 2016  Chennai, Kancheepuram, Thiruvallur coastal districts  Very severe cyconic storm  140 km wind speed, heavy rainfall  10 fishers died, 810 mechanized, 1445 FRB  and 728 Catamaran boats damaged, 7792 nets and 5931 engines damagedChennai flood (worst rain in 100  years)  November  8  to December 14, 2015  Chennai and  other parts of Tamil Nadu  Heavy rainfall,  Flooding, water  inundation Most of Chennai city flooded 422 diedPattinapakkam  Sea incursion  June 2014  Mainly Pattinapakkam  Strong wind and 10-12 high feet waves  Sea water incursion in more than 100 house holds Nilam (Deadliest cyclone)  October 31,2012  South India  Very severe cyclonic storm  1,50,000 evacuated, more than 200 boats were damagedThane  December 29,2011    Mainly Cuddalore and Puducherry   Very severe cyclonic storm,  Wind speed 140 kmph   48 died Jal   October 2010    Chennai and other parts of Tamil NaduSevere cyclonic storm    70000 evacuated,54 diedNishaTsunamiNovember December 26,200626,2008Tamil NaduNagapattinum, Kanyakumari, Cuddalore, Chennai and PuducherryCyclonic stormEarthquake - Richter scale 9,100 feet high tidesHeavy rainfall flooding189 diedIn Tamil Nadu-8000 diedNagapattinum-6000 diedPrepared by:  R.Geetha, Shoba Joe Kizhakudan, M.Shanti and P.U.
