Let's become even more concrete!
One of many ways which would lead out of the present crisis of landscape planning would be a so called "success-oriented landscape planning" (12)
This means future landscape architects should deliberately design certain cultural landscapes, that would differ from region to region due to different natural conditions and cultural aspirations!
In "success-oriented landscape planning" those parts of the landscape that are thought to be better than some well-defined "standard regional cultural landscape" could be assigned with a positive number as credit, those thought to be worse with a negative number as debt.
Changing a landscape by recultivation from -2 to -1 would be positive and could be credited on an eco-account or be paid in cash or be exchanged against negative changes in other parts of the landscape.
Many advantages can result from introducing a trading system based on the (positive or negative) results of landscape planning:
There would be a monetary, economic incentive to move towards optimal regional cultural landscapes and engage in environmentalism (water pollution control, soil protection, conservation of ancient monuments)
Improved landscapes would be tagged with a value (for example according to their costs of creation)
Improvements and degradations of landscape could be quantified.
Degradations of landscape would result in costs and would therefore be avoided voluntarily.
This single example should be sufficient.
Certainly there are, in addition, a great number of other, alternative paths leading us to the landscape of the future.
I just wanted to show you that modern holistic, comprehensive landscape planning is not a completed task that only fulfills certain requirements. Rather, landscape planning today asks for bold choices to be made, but at the same time it is an ongoing, continuously fascinating adventure. I hope I have been able to inspire you a little bit as well!
