Valuation of Ecosystem Services

Detection and Characterization of Small Water Bodies

The 48 contiguous United States contain at least 2.6 x 10 small water bodies (> 600-900 m), and possibly as many as 9 x 10 (> 25 m) (Smith et al. 2002). These water bodies are termed ‘small’ not only because of their size distributions, but also to emphasize the distinction between the water bodies discussed here and the much smaller number (a few percent of the total at most) of relatively wel...

A framework for ecosystem services valuation.

In the recent article, “Managing Invasive Aquatic Plants in a Changing System: Strategic Consideration of Ecosystem Services,” Hershner and Havens (2008) reject the need to manage certain aquatic plant invaders. The authors claim that Phragmites australis invasion is acceptable because it provides three ecosystem services: habitat, soil stabilization, and nutrient uptake and retention. We stron...

Applying CVM for Economic Valuation of Drinking Water in Iran

Economic valuation of water is useful in the administration and management of water. Population growth and urbanization caused municipal water demand increase in Iran. Limited water resource supply and urban water network capacity raised complexity in water resources management. Present condition suggests using economic value of water as a criterion for allocating policies and feasibility study...
