London's Housing Crisis - a collaborative modeling experience von Kai Neumann

On LinkedIn (https://www.linkedin.com/groups/2639211/2639211-6171315685852012548?trk=hb_ntf_COMMENTED_ON_GROUP_DI...) Bob Bollen asks for ways to model London's housing crisis. While some suggestions are rather complicated (some imho outdated) I'd like to suggest to just start with it in a way that not just experts but also stakeholders can read a model and contribute to it. So here is the start of a collaborative model.  Please ask for any further assistance / guidance using the comment functions on kno...

Biomass Web: Accra's Mini Model on Exports von Kai Neumann

Just a small model to facilitate a discussion during a workshop in Ghana. The thesis was that seasonality would lead to less exports of crops and the counter argument was that it might lead to a necessity to export if domestic demand isn't able to consume all the crops. However, if irrigation leads to less seasonality it might be possible to export more. Tricky, isn't it?

General Trend Model von Kai Neumann

The dynamics of cancer (collaborative model) von Kai Neumann

Just the start of a model since I was asked for a rather general model on this difficult topic. Since I am a layperson this model should be improved by either directly editing it via collaboration link or at least discussing it.
