    Choice Experiment Analysis of Non-market Values of Ecosystem Services
    (springer, 2022) Dissanayake, Sahan T. M.; Vidanage, Shamen P.
    Small tank cascade systems (STCS) are clusters of hydrologically interconnected irrigation reservoirs with a 2500-year history located in the dryzones of Sri Lanka. They provide irrigation to 40 per cent of the irrigable land and a host of other benefits. The maintenance of STCS was neglected historically partly due to the low recognition of their true value. We highlight how choice experiment surveys and extended benefit-cost analysis can be used to elicit the full value of conducting environmental restoration projects with application to STCS. Respondents have a positive willingness to pay for the restoration (over LKR 78 million for the onsite sample). The cost-benefit analysis proves that cascade restoration is justified.
