Green spaces are an important element against the effects of climate change. Green spaces in the city contribute significantly to a pleasant urban climate in densely built-up cities (for example used as cooling, shadow, etc.).
It is estimated that public green spaces will only grow slightly and be exposed to increasing pressure of use. At the same time, the green spaces on private ground will continuously decrease because landowners want to maximise the use of their land with high-density construction. These losses of green spaces can barely be compensated through public green spaces.
The aim of this challenge is to illustrate the development of the urban green spaces in the public and private environment and to demonstrate the impact green spaces have on the urban climate respectively the well-being of the citizens. The definition of green spaces in this context are the sum of greenery (green-volume) in the city such as trees, bushes, forests, agricultural zones, green roofs, gardens, etc.
- should simulate the future development of the green spaces in the city based on past and present data
- should include the complete tree mapping from the years 2006 and 2010 from two districts (Schwamendingen and Zürichberg), from which the development of the tree population can be derived. These findings can be extrapolated to the entire urban area
- can be a tool that should be able to be updated with current data
- can ideally be three-dimensional
- can make use of available weather data from the API of one of the most experienced providers of weather, climate and environmental data in Europe.
