Extensions? Markov chains are applicable to relatively independent environmental qualities (tree density, humus, salt, contamination) Method not suitable for complex environmental properties (climate)

Conclusions Today’s solution – tomorrow’s problem? EUFASOM aims at integrated assessments of food, climate, biodiversity, and water issues from land use Computing power and model integration offer new opportunities – what about validation?
