Peri urban farmland included in green infrastructure strategies promotes transformation pathways towards sustainable urban development Urbanization and agricultural land use are two of the main drivers of global changes with effects on ecosystem functions and human wellbeing. Green Infrastructure is a new approach in spatial planning contributing to sustainable urban development and to address urban challenges such as biodiversity conservation climate change adaptation green economy development and social cohesion.

Therefore a number of different research approaches have been applied. First a quantitative GIS based modeling approach looked at spatial potentials addressing the heterogeneity of peri urban ...
