By using the post estimates chosen above, the differences in economic benefits between scenarios with
intervention and the one without are shown in
Table 21 below and Figures 3 and 4 below. The results confirm that scenarios with interventions have
greater benefits than the scenario of no policy interventions. The benefits of the maximum wetland
vision outweigh those of the no intervention one by from £14.2 million/year to £21.1 million/year
(2008£), depending on the timing and socioeconomic conditions in the future. In comparison, the
benefits of the integrated vision exceed those of the no intervention vision by between £6.2
million/year and £9.2 million/year (2008£).
