Table 8 shows possible anticipative actions to keep open options for a shift from strategy 2 or 3 to strategy 1. According to the authors, one of the anticipative actions could be a regulation to guarantee that new infrastructure, like harbours and wharfs, have dimensions that can cope with the higher water levels of Lake IJssel. Anticipative actions such as making spatial reservations for dike broadening to prevent housing or other economic activity from blocking a switch would be useful as well. In addition, creating awareness by the public that elevating the water level in the future is still an option is another action that could be done in order to prepare the public for a possible switch. Finally, the authors were not able to identify clear anticipatory actions in order to keep the options open for transferring from strategy 2 to 3 and vice versa. This is probably due to the fact that these two strategies are not too far apart as both already focused on reducing fresh water demand.
