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.
