-- / --


Indication of the status at the beginning of the Ecolynx Project (Information Context for Biodiversity Conservation) funded by the European Union within the framework of Info2000.
See separate documents for statistics on text content (1998) and statistics on Feedback Loops Linking World Problems (2000)

The type codes by which problems and strategies are distinguished in the following table are explained in separate documents (World Problems: Type Codes; Global Strategies: Type Codes).
