The study on positive and negative externalities of coastal ecosystem with categories of serious affected, medium affected and low affected fishermen was taken up in the Cuddalore district of Tamil Nadu. Based on the intensity of pollution, they were categorized into seriously affected, moderately affected and low affected and six villages were selected with sample size of 120. The negative externality was assessed by hedonic model. For all the categories of affected fishermen, the house value was positively influenced by the household income, water quality, distance from sea and amenities of the house. Positive externalities were studied with travel cost method for mangrove and silver beach with sample size of 40 tourists for each tourist spot. The estimated total consumer surplus for mangrove forest was Rs. 199.84 crores and for silver beach, the consumer surplus was Rs. 438.60 crores.
