Spatial and temporal scales

Competing spatial claims in delta's can be related to various spatial scales, for instance:

• Local (production plot) scale: spatial concessions are given for production of specific species. This limits the possibilities for upscaling.
• Regional (Water system) scale: water systems are used by different functions. Issues as carrying capacity (in ecological and other dimensions) are relevant
• National / European scale: Existing spatial policy for near shore functions seems to be in a deadlock. There is no virtually no space to facilitate innovations in blue growth. Therefor there is a need for regime shift in policy and trying out new concepts for spatial planning.

Competing spatial claims in delta's also has various temporal scales, for instance:

• Short term: finding short term solutions to overcome specific spatial conflicts in the framework of the existing spatial policy. Few stakeholders are involved in period of several months.
• Developing and testing new concepts of spatial planning are likely to take more than a decade;
• Implementing regime shift in spatial planning will take place in the course of decades
