Assessing hotspots of cultural ecosystem services and disservices in the city of Zagreb

PPGIS (Public Participation GIS) is a tool and methodological approach for collecting spatial data primarily from non-experts about different aspects concerning places of interest. It is proven that this approach is highly useful when dealing with intangible and subjective aspects of places such as cultural ecosystem services. In the city of Zagreb, the PPGIS questionnaire was employed as a data collection method to assess and quantify the spatial distribution of perception toward cultural ecosystem services and disservices provided by urban green spaces. Precise spatial data in a point shape was collected and employed for spatial analyses. Knowing the locations and types of urban green spaces that are perceived as providers of specific service or disservice can enhance our understanding of those places and their general importance for the beneficiaries. Spatial analysis results with, among others, cartographic representation of ecosystem services’ manifestation in an urban landscape, that is, hotspot maps. Within this work, hotspots maps are produced for 19 selected attributes of cultural ecosystem services (15) and disservices (4) throughout the city of Zagreb. Hotspot maps are further enhanced by calculating spatial autocorrelation between collected spatial points for each perception attribute separately. Results emerged with different maps of point spatial distribution, hence indicating diverse usage patterns and perceptions people in Zagreb hold toward urban green spaces. While some attributes such as Cultural Identity are spatially clustered revealing locations in Zagreb perceived to be more important for providing particular cultural ecosystem service or disservice, others such as Running resulted in a more dispersed spatial pattern. Results of calculating spatial autocorrelation between points further enhanced interpretation and provided numerical values that can be used to describe produced hotspot maps. Maps are powerful and effective tools when communicating spatial information to stakeholders and policymakers in being easy to comprehend. Perception-based assessment and quantification of the spatial distribution of cultural ecosystem services and disservices in Zagreb provided useful and understandable information. Hotspots represent locations that are highly recognised, however the resulting coldspots should be acknowledged too. PPGIS questionnaire employed in the city of Zagreb proved to be an effective tool for gathering meaningful spatial data which, properly analysed, can be used as a valuable citizen’s input for enhancing planning and management practices regarding urban green spaces in the city of Zagreb.
