Illegal mining and water quality and availability (collaborative) by Kai Neumann

This is a qualitative model from an iMODELER workshop for a group of scientists from different fields from the University of Cape Coast, Ghana. Feel free to continue the modeling via this collaborative link. Here is the read-only link to the original model: http://www.imodeler.info/ro?key=CIcLFmS12YTHp4U7SkgXR9w  What is the question the model should answer: What can be done in order to mitigate the effects from illigal mining (surface mining) on the quality of water from rivers? What are the system’s bo...

Urban gardening revisited (wonna win FAIRPHONE) by Adam

I have discovered the following article that inspired me to draw a bigger picture on urban gardening - at least qualitatively. http://www.nationalgeographic.com/environment/urban-expeditions/austin/caleb-harper-innovation-in-urban-agriculture-important-because-of-climate-change/ Of course, I wonna win the FAIRPHONE (https://www.know-why.net/question/CfsXb3NvriEsmSuhnnuxsSQ)

Reflexion on thorium reactors by Kai Neumann

this is just a first scetch of a cause and effect model ... if you look at the matrix of the factor thorium reactor you will recognize that this model is dominated by balancing feedback loops (...) you may contact me (kai@ilsa.de) to get a copy of the model or even to collaboratively model it with me and others in any way: many insights and happy modeling Kai

Solution: A healthy environment on earth by Kai Neumann

A model exploring the challenge of less pollution This model is part of a series of models that could serve as examples for small models on global challenges as they could be modeled by pupils. Of course, depending on their age and the time that is available as well as the help you offer they could come up with more details. What is the model asking?The model asks for the measures for a healthier environment using the KNOW WHY Questions from the KNOW WHY Method as they show up when we use the iMODELER. I...

Solution: Where do our vegetables come from by Kai Neumann

A model explaining the basic loops of agriculture This model is part of a series of models that could serve as examples for small models on global challenges as they could be modeled by pupils. Of course, depending on their age and the time that is available as well as the help you offer they could come up with more details. What is the model asking?The model asks for the sustainability of farming using the KNOW WHY Questions from the KNOW WHY Method as they show up when we use the iMODELER. When we cont...

Winning the Fairphone: a collaborative model on the development of house (real estate) prices by Kai Neumann

This is a collaborative qualitative model on the development of prices for real estate (houses, apartments etc.). While there is already a collaborative model on the development of stock markets (https://www.know-why.net/collab?id=CzSkr0IaGNcHWA9aGfE0Y-A) I would like to gain more insights on house prices as well. Background: while the population is shrinking we still see a boom in the construction of new houses. I thought that this was only because of low interests but experts told me a couple of demogr...

Joint Report - case study 1: Impact of GMT on resource scarcity by Ulli Lorenz

“Possible impacts of global megatrends on resources scarcity (general concept from the perspective of northern Europe)”This model is the basis for the case study 1 of the report: "Impact assessment of global megatrends - Two case studies connecting global megatrends to regional topics" by UllrIch Lorenz and Hördr V. Haraldsson The case study 1 examines the general mechanism of resource scarcity. The global megatrends – as described in the State of environment report 2010 – are included in the model as we...

Mini World by Kai Neumann

altes Modell aus dem UBA-Modell-Ordner (als .cons importiert) - keine Erinnerung, wofür das gedacht war - es ist aber gut
