Complexity 
Environmental problems and related policy measures 
mutually influence each other.
Solutions 
Policies solving one problem...
Side effects 
.. may have unwanted side effects in other areas.
The biofuels example 
10% of biofuels in gasoline ordinance..
The biofuels example 
.. resulted in additional land cultivation with heavy 
environmental impacts.
The problem 
* complex relationships 
* need to priorize 
* high degree of specialisation
The result 
Unidimensional Policies.
The project 
Method and tool to trace back potential incoherencies.
Data modeled as Causal chain... 
Problem 
Root cause Goal 
[-1,0,+1] 
Resulting behavior Measures
Incoherent policies 
Goal

(-) 
(+) 
.. trigger a behaviour which increases the problem pressure for other problems.
