This article presents an analytically focused case study of Shenzhen, a national Sponge City pilot, to examine not only whether nature-based interventions are associated with flood-resilience gains but also under what spatial, institutional, and governance conditions such gains emerge. The study adopts a qualitative mixed-methods case-study design based on secondary sources, integrating observed flood-event records, reported hydrological and water-quality indicators, model-based projections, and systematic policy analysis. Drawing on data from 2006\u20132020, the analysis explicitly distinguishes observed outcomes, reported performance indicators, and inferred effects, addressing a key methodological limitation in existing Sponge City assessments. Results indicate that, within designated pilot zones, Sponge City interventions are associated with reduced surface runoff, attenuated peak flows, and reported improvements in pollutant filtration, particularly where green infrastructure density and monitoring capacity are high. However, these performance patterns are spatially uneven and mediated by governance constraints, including institutional fragmentation and maintenance capacity. The principal contribution of the study lies in identifying governance\u2013infrastructure mechanisms that condition Sponge City performance and scalability. By treating Shenzhen as a critical rather than representative case, the article offers analytically transferable insights into the effectiveness, durability, and limits of nature-based flood-management strategies in high-capacity urban contexts.<\/jats:p>","DOI":"10.3390\/urbansci10030135","type":"journal-article","created":{"date-parts":[[2026,3,3]],"date-time":"2026-03-03T09:45:12Z","timestamp":1772531112000},"page":"135","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["From Concept to Practice: Evidence and Lessons from Sponge City Implementation in Shenzhen, China"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8497-4798","authenticated-orcid":false,"given":"Hugo","family":"Pinto","sequence":"first","affiliation":[{"name":"Research Centre for Tourism, Sustainability and Well-Being (CinTurs)\u2014Gambelas, 8005-139 Faro, Portugal"},{"name":"Faculty of Economics, University of Algarve, Portugal\u2014Gambelas, Edif\u00edcio 8, 8005-139 Faro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-7500-5111","authenticated-orcid":false,"given":"Jennifer","family":"Elston","sequence":"additional","affiliation":[{"name":"Research Centre for Tourism, Sustainability and Well-Being (CinTurs)\u2014Gambelas, 8005-139 Faro, Portugal"},{"name":"Faculty of Economics, University of Algarve, Portugal\u2014Gambelas, Edif\u00edcio 8, 8005-139 Faro, Portugal"}]},{"given":"Ojo Segun","family":"Sunday","sequence":"additional","affiliation":[{"name":"Institute of Engineering, University of Algarve, 8005-135 Faro, Portugal"}]},{"given":"Carla","family":"Nogueira","sequence":"additional","affiliation":[{"name":"Research Centre for Tourism, Sustainability and Well-Being (CinTurs)\u2014Gambelas, 8005-139 Faro, Portugal"},{"name":"Faculty of Economics, University of Algarve, Portugal\u2014Gambelas, Edif\u00edcio 8, 8005-139 Faro, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"521","DOI":"10.1007\/s11069-017-2977-1","article-title":"Understanding the challenges for the governance of China\u2019s \u201csponge cities\u201d initiative to sustainably manage urban stormwater and flooding","volume":"89","author":"Jiang","year":"2017","journal-title":"Nat.
