Methodology: regression methods
Region: Asia

Addtional Notes

The study finds that mangroves significantly reduced the number of deaths during the 1999 cyclone that struck the east coast of India, although an early warning issued by the government evidently saved more lives than the mangroves did. The study concludes that the opportunity costs of saving a life by retaining mangroves is less than the value of reductions in mortaility risks implied by wage differentials in India.
