Conserving Wetlands: Valuation of Indirect Use Benefits of a Wetland of Dhaka

Rezwana Rafiq, Md. Shahabul Alam, Md. Mafizur Rahman, and Ishrat Islam
Abstract—Wetlands act as natural sponges that trap and slowly release waters over time and help in controlling floods. At the same time, they retain water and provide time for infiltration of water for groundwater recharge. But these intangible benefits are not properly assessed in developing countries. The significant problem is that such benefits cannot be evaluated as the same way as the market goods. In this context, nearly 11 sq. km area of the western flood plain of Dhaka is selected as the study area. To evaluate the flood control function of the site, Damage Cost Avoided Method is applied. And to evaluate the ground water recharge function at first total recharge quantity in a year is estimated than the quantity is valuated. Finally, the estimated value of these indirect use benefits of the site amounts to USD 0.13 million per sq. km in a year.

Index Terms—Economic valuation, indirect use benefits, damage cost avoided method, wetland management.
