2 Spatial Planning in Flanders, Belgium history 1995 Spatial Structure Plan Positive points Scientific basis Developed bottom-up: in consultation with the population; Only the main lines for development are fixed; Departs from what exists: available space, activities present, ; Guiding principles are Integration and Sustainable Development ; Main Principles: Protect and expand the remaining rural areas and open space. Hard boundaries!! De-concentrated bundling Selective expansion of urban areas; Optimise economic development and transportation Apply Subsidiarity principle

3 1 Structure: bring more structure into space 14 urban areas 5 urban networks 2 economic networks Enable new housing (60% of demand) Improve existing housing (40% of demand); Fill gaps in the existing housing areas; Keep plots small; Keep small villages in their original state; Concentrate economic development in urban networks and industrial corridors

4 2 Select and put boundaries: protect and expand valuable nature 7 large, contiguous rural areas Valleys of streams and small rivers Most importantly: do not give up any natural areas nor open spaces. Expand them and bring them back to a more pristine state.

5 3 Combine and Link structures: enabling biodiversity and economic exchange 5 connections between rural areas 4 sea ports 2 airports 2 High Speed Train stations Few new roads! Improve existing roads; Establish a hierarchy of roads; New impetus for rail transport Improve public transport in the suburban areas;

6 Subsidiarity principle applies Each Province develops a plan that fits within the Flanders plan; Plans at Province-level are both a guideline and a constraint for Municipal-level Each Municipality develops its plan which fits within the Provincial plan.

7 Problems The plan took a long time to be implemented: bad practices are not coming to a halt; Implementation is at the municipal level: the greater picture gets lost; The plan is overly static: it draws sharp borders, but urban dynamics spill over the borders. The social space is undervalued. Number fetishism is caused by the strict spatial delineations; Sustainable spatial development is defined in terms of: spatial carrying capacity refers to efficient usage of the environmental resource space spatial quality puts the emphasis on assessment by the public. This is socially and culturally determined and hence time-dependent. The aspect equity is undervalued: who gets the benefits and who is to pay for it and how are the benefits and burdens shared among the current and the future generations? Scenario analysis, such as defined in Sustainability Exploration will be deployed to review the plan. It should be ready by 2012.
