Abstract:
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.
