Cost-effective control of SO2 emissions in Asia

Article Abstract:

An extension of the RAINS-Asia integrated assessment model for acidification in Asia with an optimization routine used to identify cost-effective emission control strategies that achieve environmental targets for ambient SO2 concentrations and sulphur deposition at least costs is presented. It is observed that strategies that address harmful population exposure as well as the risk of vegetation damage from acid deposition results in the most cost-effective use of resources spent for emission controls.

Changing abundance of elephants and willingness to pay for their conservation

Article Abstract:

The way in which the willingness to pay for the conversation of Asian elephants in Sri Lanka varies with hypothetical variations in their abundance is explored. It is suggested that willingness to pay for conservation of a species rationally includes a strategic element and might not always measure the total economic value of a species.
