“…Globally, urbanization is accelerating, resulting in the destruction of natural riverbanks and, consequently, seriously affecting the ecological functions of riparian zones [ 7 , 8 ]. Similar to most studies on the impacts of urbanization on biodiversity [ 69 , 70 ], we detected an overall negative effect on the abundance and richness of the soil animal community at high urbanization levels.…”

“…In our study, the differences in revetment structure, human density, air or soil temperature, and vegetation composition were important embodiments of urbanization levels and were closely related to soil fauna diversity. The most obvious hydrological change associated with urbanization is the engineering of stream channels, in which natural features are replaced by concrete channels and streambank stabilization efforts designed to resist increased flood flows [ 7 ]. In such an approach, the riparian vegetation is replaced by an impervious or less-permeable surface, which alters the rates and pathways of water movement into, through, and out of ecosystems [ 7 ].…”

In such an approach, the riparian vegetation is replaced by an impervious or less-permeable surface, which alters the rates and pathways of water movement into, through, and out of ecosystems [ 7 ]. Walsh et al [ 74 ] described the “urban stream syndrome” and suggested that urban riparian zones may exhibit reduced water and nutrient infiltration because natural terrestrial pathways are often bypassed due to stormwater drainage networks.…”

“…Riparian zones are generally regarded as functionally unique ecosystems [ 1 ], and numerous studies have investigated the biodiversity of plants [ 3 ], birds [ 4 ], insects [ 2 , 5 ], and microbes [ 6 ] in these river–land interfaces. However, these ecosystems face multiple stresses such as global climate change, land-use conversion, reshaped water regimes, increasing human interference, biological invasion, and other site-specific issues which are mainly the results of increasingly expanding urbanization [ 7 ].…”

Urbanization is accelerating worldwide, resulting in drastic alterations of natural riverbanks, which seriously affects the ecological functions and services of riparian landscapes. Our understanding of how anthropogenic activities influence soil animal communities within riparian zones is scarce. The soil fauna represents an important biotic component of the soil ecosystem and greatly contributes to soil structure and fertility formation. We investigated the richness, abundance, diversity, and distribution of soil animal groups, including macro- and mesofauna, in different riparian landscapes along an urban–rural habitat gradient. In natural riparian zones with permeable revetments, the soil fauna was richest and most abundant, mainly because of the low levels of human disturbance and the more suitable habitat conditions. Different soil animal groups responded differently to revetment type and distance from the water flow. The hygrophilous soil mesofauna, requiring a more humid environment, was more sensitive to shifts in revetment types, the location on the riverbank, and the seasons. In summer, when precipitation in the study area was highest, the abundance of the hygrophilous soil mesofauna was significantly higher than in autumn. Distance from the water flow significantly affected the abundance of the hygrophilous soil mesofauna. Our results demonstrated that hygrophilous soil mesofauna can serve as a good indicator in riparian zones, reflecting the hydrological conditions. We also observed interactions between revetment type and distance from the water flow; the distance effect was stronger in the natural riparian zone with a permeable revetment type. Our results highlight the importance of anthropogenic effects on soil ecosystem processes and functions in riparian landscapes, and the necessity of protecting and retaining the natural riverbank and native vegetation patches in riparian landscape planning and construction.

A novel framework is presented that aims to guide practitioners and decision makers toward a better understanding of the role of nature-based solutions (NBS) in the enhancement of resources management in cities, and the mainstreaming of NBS in the urban fabric. Existing frameworks describing the use of NBS to address urban challenges do not specifically consider circularity challenges. Thus, the new framework provides the following: (1) a comprehensive set of Urban Circularity Challenges (UCCs); (2) a set of more than fifty NBS units and NBS interventions thoroughly assessed in terms of their potential to address UCCs; and (3) an analysis of input and output resource streams, which are both required for and produced during operation of NBS. The new framework aims to facilitate the coupling of individual NBS units and NBS interventions with NBS that enable circular economy solutions.
