“…Urban rivers in the Latin American and Caribbean (LAC) region have been con gured as degraded and emerging landscapes, as they are subjects to the impacts of urbanization, one of the anthropic dynamics that have most altered watercourse (McGrane, 2016; Meyer et al, 2005), in addition to aggressive and polluting practices such as waste dumping, deforestation (Rocha et al, 2022) and a clear trend towards structural solutions, such as canalizations (Portugués-Mollá et al, 2016). All of these are stress factors that threaten biodiversity, ecological functions and thus the resilience capacity of these landscapes against hydrological events and the effects of climate change, such as oods (Benítez et al, 2012).…”

Context: The progressive degradation of urban rivers has serious socio-ecological impacts, compromising the provision of ecosystem services (ES), thus affecting the quality of life of the inhabitants, however, few are integrated into the social perspective together with the diagnosis of the immaterial and non-monetary benefits as complementary knowledge to traditional approaches. Objective This work sought to add complexity to the diagnosis of the ES, through the identification and mapping of the positive and negative landscape preferences of the local community concerning the urban fluvial landscape of the Zamora and Malacatos rivers in the urban-periurban environment of the city of Loja in Ecuador. Methods This work is resolved with the dissemination of a virtual geo-form, processed with the SolVES model, a participatory mapping tool (PPGIS) that integrates social and biophysical variables. Results The value points obtained revealed different spatial patterns for each social value group. The positives exhibited more dispersed patterns, clustering in peripheral areas. The negatives were concentrated in the centre of the city. Of the ten social values studied, the most relevant were: Learning, Aesthetic, Therapeutic and Disgust, Poor and Inaccessible Infrastructure, and Flood Threat. The environmental variable with the greatest contribution was the Horizontal Distance to Green Areas. Conclusions The results help to identify possible places of conflict as well as attractive locations based on place-based knowledge, which enables a better understanding of the value of the benefits of urban rivers, further, it stimulates the inclusion of the local community in the development of more participatory management and governance and sensitive to the landscape.
