Coastal regions are among those most vulnerable to climate change to both sea level rise and extreme weather events, in particular to tropical cyclones, as it is felt that the principal impacts of climate change are likely to be manifested and perceived through changes in the frequency or intensity of extreme weather events. A study has been carried out to assess the susceptibility of coastal districts i.e their vulnerability to hazards (frequency and landing of severe storms on coastline), exposure (population density and housing index), and likely impacts due to climate change (cumulative, per lakh population and per event deaths). Presently, Jagatsinghpur and Kendrapara (earlier parts of Cuttack), Nellore, Nagapattinam, Junagadh and Porabandar districts are highly vulnerable to impacts of climate change. North 24 Pargana, South 24 Pargana, Baleshwar, Bhadrak, Srikakulam, East Godavari, Guntur, Krishna, Thiruvallur, Cuddalore and Ramnathpuram are somewhat vulnerable. All other coastal districts are less vulnerable. There may be additional factors that reduce impacts, such as genetic resilience of the exposed populations, traditional survival methods, mangrove ecosystems near the storm landing etc., as indicated by the 24 Pargana districts that have low impacts despite high hazard and exposure levels. These require further studies. The paper begins with a brief review of the current state of knowledge with regard to the impacts of the climate related natural hazards (mainly sea level rise) in the coastal zones across the world as well as in India.

India’s Initial National Communication
(NATCOM) to the United Nations Framework Convention on Climate Change |
| About NATCOM |
In pursuance of the implementation of the United Nations Frame work Convention on Climate Change (UNFCCC), Government of India has initiated a project towards the preparation of India's Initial National Communication. This project is being executed by Ministry of Environment and Forests and is funded by the Global Environment Fund through the United Nations Development Programme, India. The elements of information are as per the Article 4 and 12 of the Convention, stipulated for Developing Country Parties. The information will include a national inventory of greenhouse gases emitted from anthropogenic sources and removal by sinks and which are not controlled by Montreal protocol; a general description of steps towards implementation of the convention and other relevant information which indicate India's commitment to sustainable development. |
