Contingent valuation, conjoint experiment elicitation and behavioural economic valuation of Koothapar big tank wetland - P 163-168

In recent decades, wetlands have deteriorated due to biotic and abiotic threats. Hence, ecosystem service valuation is sine quo non for its conservation. This was
estimated through novel environmental impact assessment methodologies of contingent valuation, conjoint
experiment elicitation and behavioural economic valuation of Koothapar big tank wetland, Tamil Nadu, in
the Indian context. The estimated economic value of
non-use value through contingent valuation was Rs
81.95 lakhs per annum. The estimated total economic
value for biodiversity conservation through conjoint
experiment was Rs 85.50 lakhs per annum. The inclusion
of behavioural economics in the study showed that its
willingness to pay value was higher than the stated
preference approach by 30.52%.
