Severe weather conditions and urban intensification are key factors affecting the response of combined sewer systems, especially during storm events. In this regard, capacity assessment networks under impact rainfall events different return periods was focus work. The selected case study area a mixed-use catchment in city centre Thessaloniki, Greece. hydraulic performance examined network assessed using an InfoWorks ICM model. results indicated that mitigation strategies, such as application nature-based solutions (NBSs) or low-impact developments (LIDs) considered essential for controlling overflows. A multicriteria analysis conducted to select most appropriate NBSs/LIDs be located enhance system’s capacity. were used propose overflow scenario, based on installation green roofs, highly ranked solution performed. Incorporating proposed NBS/LID hydrologic-hydraulic model significantly increased studied network.

The escalating biodiversity crisis, coupled with the increasing frequency of droughts and anticipated water shortages due to climate change, necessitates a shift towards biodiversity-led landscape architecture, including domestic gardens. Traditionally viewed as high-maintenance spaces emphasising tidiness, gardens can significantly impact urban green infrastructure species richness. This paper explores concept ‘savage gardens’—untamed natural representing fourth nature approach, incorporating wild neglected areas. Despite potential challenges in public appreciation, it is argued that savage offer substantial benefits, such reduced maintenance, increased biodiversity, enhanced resilience change. By reframing perception ‘savage’ from biophobic reconnection nature, are proposed viable solution for balancing aesthetics, ecosystem services, landscapes, promoting more sustainable future face emergency.

Urbanization increases the number of impervious surfaces in watersheds, reducing infiltration and evapotranspiration, which runoff volumes risks flooding pollution water resources. Nature-based solutions (NBS) mitigate these effects by managing volume quality, restoring hydrological cycle, creating sustainable livelihoods that can promote socioeconomic equity providing green space. In light aforementioned information, this study analyzes response NBS La Guapil, a densely populated socioeconomically vulnerable area Costa Rica with approximately 80% surfaces, focusing on their effectiveness stormwater management improving conditions. Field data from area’s storm drainage system, as well analyses, were collected processed to evaluate RCP8.5 climate change scenarios using Clausius–Clapeyron (CC) relationship. Three proposed: (1) “status quo”, reflecting current conditions, (2) roofs improvements, (3) detention ponds evaluated SWMM, latter scenario also Iber model. Simulations showed Scenario 2 achieved greatest reduction peak flow (53.74%) (57.60%) compared 3 (peak: 28.37%; volume: 56.42%). Both demonstrate resilience projections. The results provide foundation for further research into other comparable regions.
