Bioswales as Engineering Functions of Nature-Based Solutions to Increase Urban Resilience: A Review

Abstract

The increasing challenges posed by climate change are having a more pronounced impact on urban areas than ever before. To ensure the well-being of urban residents, it is imperative to allocate resources for both theoretical knowledge and practical implementation of urban green infrastructure in adaptation and mitigation measures. Nature-based solutions offer a multifaceted approach to addressing these complex challenges. Among these innovative strategies, bioswales emerge as a fundamental and widely adapted element in urban areas, designed to manage stormwater runoff effectively. The successful implementation of bioswales relies on factors such as the choice of materials, orientation, and location within the urban landscape. A systematic literature review was conducted to establish a comprehensive framework for the use of bioswales concerning ecosystem services and their impact on the quality of urban residents’ lives. This review aimed to scrutinize case studies that examined the selection and engineering aspects of bioswales based on site-specific and climatic conditions, available resources, performance, maintenance, and design decisions. The resulting framework promotes the use of bioswales in the aspect of technological, natural, and socio-economic systems for the sustainable resilience of the cities. The research findings suggest that by optimizing the integration of bioswales with urban elements and improving maintenance practices, there is the potential for a significant and lasting improvement in the quality of urban life. Given the complex landscape of governmental policies and the limited body of research addressing the accessibility and engineering system of nature-based solutions, there is a need for future investigations that involve real-life implementations and additional case studies.
