A dam construction proposal for stable water supply was evaluated using the emergy concept to illustrate an application of this new concept in cost-benefit analysis of development proposals of natural environments. Emergy concept tries to evaluate the contributions of environmental resources to the real wealth of our economy. Models for emergy evaluation were constructed with the energy systems language; a symbolic modeling language that shows network properties of systems holistically, Water supply accounted for most emergy benefit of the dam construction. Increase in the aquatic productivity, another emergy benefit of the dam construction, was very minor in the total emergy benefit (less than 0.01%). Major emergy costs were in construction cost (28.2%), operation and maintenance (27.2%), social disruption (22%), and resettlement of People (12.5%). Emergy yield ratio was 1.06 when sediments were not included, and 1.02 when sediments were included, which resulted in small net yield in both cases. Emergy cost-benefit evaluation yielded less benefit for the proposed dam construction compared to that evaluated by the traditional cost-benefit analysis, 1.62. The emergy yield ratio would fall below 1.0 if rare species within the system boundary are lost as a result of the dam construction, because of the high emergy value included in biotic species. In this case, emergy costs will be greater than emergy benefits. This study illustrated a new methodology in assessing effects of development proposals of natural environments.
