Evaluation and mapping of the positive and negative social values for the urban river ecosystem

Abstract

Urban rivers play a crucial role in providing ecosystem services (ES) that contribute to the social well-being and quality of life of urban inhabitants. However, rapid urbanisation has led to the progressive degradation of these rivers, affecting their capacity to deliver ES and resulting in significant socio-ecological impacts. This study performs a participatory mapping of the non-monetary social values (positives and negatives), in the urban Zamora and Malacatos Rivers and their ESs, in Loja, Ecuador, to understand community perceptions and preferences in a context of degraded landscapes as a complementary category of analysis to traditional approaches. Methodologically, the collection, analysis and mapping were carried out using public participation GIS (PPGIS) based on surveys. This method facilitated the integration of social data with biophysical variables. The most relevant of the ten social values studied were positives: Learning, Aesthetic, Therapeutic and negatives: Displeasure, Deficient and Inaccessible Infrastructure and Threat of Flooding. We revealed different spatial patterns for each ES social value, where positive value locations exhibited a dispersed pattern, with clusters in peripheral areas, while negative value locations exhibited a clustered pattern in the city centre. The environmental variable with the most significant contribution was the Horizontal Distance to Green Areas. These findings enhance our understanding of the social values and preferences associated with ES in urban river contexts. Furthermore, they provide valuable insights for identifying areas of opportunity and conflict, informing community planning and effective management of the urban landscape.
