The image represents the Roeterseilandcampus (or: the campus of the University of Amsterdam), which is used by many individuals during daytime. This green public space brings (many) benefits, such as increased physical activity associated with enhanced health (Woodcock et al., 2009). Besides this, urban parks also often increase the psychological well-being of individuals due to reduced stress levels (Ernston, 2012). However, solely students have access to this green space, which is (at first) not visible in this image. The uneven accessibility of green spaces has become recognized as an environmental justice issue: non-students have less access to this public space and so less access to the additional benefits of green spaces (Dai, 2011). Secondly, there are many people in this picture, which gives the impression of feelings of safety due to the "eyes on the streets" (Jacobs, 1961). However, during the night, the place is not being used due to the lack of street lighting, which contribute to feelings of unsafety (Foster & Giles-Corti,2009). Hence, this invisible information is crucial in order to plan for a more livable space. First of all, the knowledge can 1) decrease socio-spatial inequality and 2) increase feelings of safety with street lighting.
