Greener, Wilder, Better: Valuing Complexity and Diversity in Urban Riparian Areas

Abstract

(1) Riparian areas are among the most valuable ecosystems on earth due to their high biodiversity and contributions to human well-being, yet urban riparian areas face significant threats from urbanization and associated expansion. Current management strategies do not consider all the contributions of urban green spaces to human well-being. Over the last decade stated preference studies have been widely used to gain insights into public attitudes towards urban green spaces. However, whether and to what extent the public values urban biodiversity in urban riparian areas remains unclear. (2) We used a discrete choice experiment approach to determine public preference for urban biodiversity and management interventions in urban riparian areas through a discrete choice experiment conducted in Poland. (3) We found strong positive preferences for highly complex and dense vegetation along urban riparian areas, indicating a public inclination towards enhancing natural biodiversity in public spaces. Additionally, respondents expressed a preference for reducing impermeable surfaces, such as concrete pathways, highlighting the value placed on minimizing urban encroachment. (4) Willingness-to-pay (WTP) results suggested that the public in Poland is prepared to financially support certain biodiversity conservation measures and land-conversion interventions in urban green spaces. (5) These results underscore the importance of integrating ecological research and public preferences into urban riparian management strategies, emphasizing the need for policy approaches that prioritize biodiversity conservation while balancing urban development.
