Cost benefit analysis of peri-urban land use policy - Plurel

Results and discussion
Table 19 exhibits the estimated aggregate economic benefits for each of the three planning visions.
Overall, the wide ranges of the estimation results reflect the fact that the benefits of zone are highly
subject to its geographic location, the characteristics of the ecosystems located in this area, etc. This,
however, can increase the ambiguity with any implications drawn from these results.

Given the wide ranges of estimated benefits as shown in the table above, this study alternatively
develops point estimates as the best guesses for the study site. To select these point values, we choose
the values transferred from studies originally carried out in the UK, or otherwise use the median
value of a selection of original estimates, as shown in Table 14.
