Using Deep Learning Models for Standardised Assessments of Urban Ecosystem Services
The benefits that humans receive from their environment, commonly classified as ecosystem services (ES), has a high demand in cities due to the increased population density. As the urban footprint escalates with human population growth, urban ecosystem services (UES) must be considered in urban planning and policymaking. This study seeks to establish a replicable methodology for assessing UES across multiple cities, in order to establish standardised metrics and comparative analyses. Current research trends focus primarily on case studies that are contextualized to the given city, limiting the research’s applicability in cross-city comparisons or in developing state or federal policy (García-Pardo et al., 2022). The MAES 4th Report published by the EU JRC (Maes et al., 2016) was used as an international standard for categorizing UES and their associated service providing units. Furthermore, AI and deep learning models are investigated as a tool for efficient and accurate landcover assessments in the urban environment. Applicationa and limitations of ES matrices are highlighted. An alternative approach to ES matrices is proposed, using the MAES 4th report UES providing units and the landcover classifications of the Esri “High Resolution Land Cover Classification – USA” deep learning model. This standardises “Traffic Light” UES matrix is then combined with the outputs of the deep learning model to estimate the relative presence of five regulating UES across ten US cities. Average accuracy per landcover type and per city were calculated, and F1 scores were used for statistical analysis. The initial results of the study are promising, with the adjusted data achieving an average of 89% accuracy per city. In terms of landcover type accuracy, the average for the adjusted data was 88% with F1 scores ranging from .82-.94. calculations for average UES values for the ten cities were also calculated, with notable differences in values between temperate and arid cities. Applications for the methodology are discussed, ...
