Abstract:
... Estimation of the Total Economic Value (TEV) of a tropical forest comprised the Direct Use Value (DUV), Indirect Use Value (IUV) and Non-Use Value (NUV) components of the TEV. DUV was measured based on the timber and recreation values, which contributed the largest share of the TEV. IUV was measured based on the carbon sequestration and watershed services values, which contributed the second large ...
