“…In conclusion, the authors argued for viewing private gardens or small green spaces collectively as interconnected patches and networks instead of separate entities. Accordingly, considering small-scale fragmented surfaces and surface patches is necessary for urban development planning (which is less explored [49]).…”
Densely built-up areas are challenged by reduced biodiversity, high volumes of runoff water, reduced evaporation, and heat accumulation. Such phenomena are associated with imperviousness and low, unsustainable utilisation of land and exterior building surfaces. Local authorities have multiple objectives when (re-)developing future-proof districts. Hence, exploiting local potentials to mitigate adverse anthropogenic effects and managing the resource of urban land/surfaces have become key priorities. Accordingly, a five-level hierarchy for a land-sensitive urban development strategy was derived. To support the operationalisation of the hierarchy, we present the model Namares, a highly resolved GIS-based approach to enable spatially explicit identification and techno-economic and environmental assessment of intervention measures for advantageous utilisation of available surfaces per land parcel. It uses existing data and covers the management of economic, natural, and technical resources. Nine intervention measures are implemented to identify potentials, estimate investments and annual costs, and assess the appeal of existing subsidies. The approach was applied to a case study redevelopment area in a large city in Germany. The results provide spatially explicit information on greening potentials, estimated investments, subsidy demand, and other quantified benefits. The case study results show the limited potential for additional unsealing of impervious surfaces by transforming ca. 10% of sealed ground surface area into new urban gardens. At the same time, up to 47% of roof and 30% of facade surfaces could be utilised for greening and energy harvesting. The approach enables a comprehensive localisation and quantitative assessment of intervention potentials to enhance decision support in land-sensitive urban development strategies.

“…The difficulty of integrating green spaces into urban areas, which are almost fully occupied, has led to the implementation of hybrid systems that integrate greenery into or on top of gray infrastructure, such as green walls and roofs, permeable paving and roadside channels or gutters, shorelines, designated green belts, and walking paths in larger urban areas [ 86 ]. The benefits of integrating these practices in urban areas are very important for people’s health [ 87 , 88 ], air quality regulation, local temperature regulation, pollution abatement, and leisure opportunities [ 89 , 90 , 91 ]. Numerous recent studies claim that green infrastructures are the most effective practices to promote cooling through shading, airflow orientation, precipitation interception, and evapotranspiration [ 92 , 93 , 94 , 95 , 96 , 97 ].…”
Section: Urban Practices To Mitigate Soil Sealing: Typologies Charact...mentioning
Soil sealing is one of the most serious environmental problems today regarding its impact on cities. This article presents an analysis of the different urban practices currently used to mitigate the effects of soil sealing in urban areas. The main typologies, characteristics, differences, similarities and objectives have been considered. The practices analyzed were SuDS (Sustainable Drainage Systems), LIDs (Low Impact Developments), BMPs (Best Management Practices), WSUD (Water Sensitive Urban Design), GI (Green Infrastructure), and NbS (Nature-based Solutions). To understand the impact of these terms, an analysis of their presence in the scientific literature over the last 10 years is carried out. The results indicate that the trend in the use of these terms is increasing, with the number of articles having doubled in the last 10 years. This indicates the importance that the problem of soil sealing has acquired in the world, and the relevant environmental benefits of addressing it.
“…Urban green spaces such as public parks provide a number of ecosystem services that help to address challenges related to climate change and urbanization [ 1 , 2 ]. Vegetation regulates the microclimate through shading and transpiration, and green spaces promote physical activity, relaxation and social interaction and thus are beneficial for human health and wellbeing [ 3 , 4 ].…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
