Scenarios for the Oudlandpolder

The scenarios that are presented in this report, are developed in collaboration with the VLM and several thematic experts, among which also representatives of the Oudlandpolder planning guidance group. They consist of narratives and figures explaining the uncertain evolution of several factors external to the Oudlandpolder system we modelled, such as changes in land use, population growth or (technological) developments in urban water management systems, hence factors going beyond the control of the people involved in the Oudlandpolder’s development at a local and regional scale.Notwithstanding this, these external evolutions may impact the development of the Oudlandpolder.  That is why we tried to come to a clear understanding of their true nature, and linked them to the Oudlandpolder’s SD model. The latter implies that we scaled down these external uncertainties to the level of the modelled system and defined input variables where these external uncertainties connect with the processes giving rise to the Oudlandpolder’s internal functioning.
