THE CONCEPT OF THE SPONGE CITY AS AN ELEMENT OF ECOLOGICALLY SUSTAINABLE URBANISM: THE CONCEPT OF THE SPONGE CITY AS AN ELEMENT OF ECOLOGICALLY SUSTAINABLE URBANISM

Abstract

Abstract. In the context of intensifying climate challenges and the rapid growth of urbanised territories, the search for sustainable models of urban water resource management has become increasingly important. One of the promising approaches within nature-based urbanism is the Sponge City concept, aimed at restoring the natural water cycle and creating climate-resilient urban infrastructure.

The aim of this study is to analyse the theoretical foundations and practical mechanisms for implementing this concept within sustainable urban development. The methodological framework includes comparative and systemic analysis of international experience in nature-based solutions, as well as the study of Low Impact Development (LID) principles that integrate natural water regulation mechanisms into urban landscapes.

The study examines key elements of hydro-ecological infrastructure, including permeable surfaces, green vegetation systems, water-retaining landscapes and biofiltration systems. Practical case studies include projects by the Turenscape architectural bureau: Qunli Stormwater Park in Harbin and Yanweizhou Park in Jinhua (China), as well as Bishan–Ang Mo Kio Park in Singapore.

The results demonstrate that the implementation of sponge city principles enhances the ecological resilience of urban environments, improves microclimatic conditions and reduces risks associated with extreme hydrometeorological events. Nature-based solutions therefore contribute to the formation of a new paradigm of sustainable urbanism.
