Inner city neighbourhoods are often charged with a double task: they must nurture socio-economic areas so that they produce new practises which lead to wealth creation, yet they must also lessen social polarisation by creating environments where social and ethnic integration can take place. This dilemma must be viewed through a useful framework. Gentrification 2.0 is a project that argues that gentrification, despite its many critiques, remains a useful concept when analysing strategies designed to solve this dilemma. Gentrification 2.0 uses an interdisciplinary approach to closely examine the inner city neighbourhoods of Zurich, Istanbul, Vienna, and Arnhem. The project analyses these cities by using the opinions and experiences of all the stakeholders, including citizens, to map demographic, economic, and planning developments. Gentrification 2.0 argues this method will generate new ideas to improve these neighbourhoods and in turn solve this dilemma. The insights of stakeholders will be published on the participatory website, which uses exciting GIS in order to visualise the project’s results for the local communities.
