This new technology has turned a large intact coastal sand area into shrimp ponds by digging ponds covered with plastic sheets and cement consolidated edges. The rapid development of coastal sand shrimp ponds have brought in such main environmental impacts as ground water depletion, loss of forest and agricultural land partly due to salinity invasion; increasing sand storm; loss of onshore sea products and decreased shrimp yields due to pollution. This study provides a spreadsheet model for local authority to make decision on land use using cost benefit analysis as a decision tool. This study shows that despite of yield risks, individuals still have incentives to continue with existing unsustainable farming practices as this activity is financially profitable on average. However, the net social benefits of this practice is negative.

Results show that tourists are more willing to pay for an ‘environmental tax’’ than a general‘‘ tourism development tax’’. The study found that an environmental surcharge of US$2 per person could generate $3.4M per year for management with 0.2% rate of decline in tourist visitation. Negative impacts from the imposition of additional taxes on annual tourist visitation rates could be minimized by providing information on how there venues from the tax will be allocated for management activities.

Theoretical as well as empirical research shows that mangroves provide protection from storm surge. But whether mangroves protect inland static property during storms is less explored. This paper estimates the storm protection benefits due to mangroves during the super cyclone of 1999 in Orissa. By combining GIS data with census information, the paper examines the mangrove mediated effects on residential property in the Kendrapada district of Orissa. The analyses suggest that the percentage of fully collapsed houses in the study area would have increased by 23% without the benefit of mangrove protection. On the other hand, if the mangrove cover had remained at the level that it had been in the 1950s, the area would not have suffered any fully collapsed houses at all. The total protection benefits of mangroves in terms of averted damages to residential property in Kendrapada are estimated to be INR 592,647,800 (USD14, 110, 662). This suggests that mangrove forests provided protection benefits to houses to the extent of INR 975, 800 (USD 23,233) per km width of forests or INR 51,168 (USD 1218) per hectare of forests. Thus, policy makers need to take mangrove conservation and re-planting into account in planning for tropical storms, which are expected to increase with global warming.
