“…This trend could be interpreted almost as an unquestionable, unconscious frame: in order to count as an NBS unit, a solution must be green. In the specialized literature, NBS are often related to expressions such as "greening of cities" (Tozer et al, 2020), "urban green space" (Panno et al, 2017), "urban greening" (Dorst et al, 2019 andEscobedo et al, 2018), "greening strategy" (Fastenrath et al, 2020) and "green placemaking" (Gulsrud et al, 2018). This frame can be explained by the need to distinguish the natural foundation of NBS in comparison to other conventional grey infrastructure.…”

The concept of Nature-Based Solutions (NBS) has emerged to foster sustainable development by transversally addressing social, economic, and environmental urban challenges. However, there is still a considerable lack of agreement on the conceptualization of NBS, especially concerning typologies, nomenclature, and performance assessments in terms of ecosystem services (ES) and urban challenges (UC).Therefore, this article consolidates the knowledge from 4 European projects to set a path for a common understanding of NBS and thus, facilitate their mainstreaming. To do so, firstly, we performed elicitation workshops to develop an integrative list of NBS, based on the identification of overlaps among NBS from different projects. The terminologies were formalized via web-based surveys. Secondly, the NBS were clustered, following a conceptual hierarchical classification. Thirdly, we developed an integrative assessment of NBS performance (ES and UC) based on the qualitative evaluations from each project. Afterwards, we run a PCA and calculated the evenness index to explore patterns among NBS. The main conceptual advancement resides in providing a list of 32 NBS and putting forward two novel NBS categories: NBS units (NBSu) that are stand-alone green technologies or green urban spaces, which can be combined with other solutions (nature-

“…The example of the upstream-downstream challenges facing WRUAs in Kenya brings us to the third theme: scale. A debate is emerging about extending, linking or merging successful NbS case studies -often described as "scaling-up" (Fastenrath et al 2020;Ramiller and Schmidt 2018). Despite increasing interest in mainstreaming NbS (Nesshöver et al 2017;Wamsler et al 2017), little is known about the mechanisms and conditions necessary for scaling them up in practice.…”

“…Misinterpretation of scale can produce suboptimal outcomes for the resilience and sustainability of human-environmental systems (Fastenrath et al 2020). Particularly challenging are the social scale limits such as adjusting to and/or the introduction of newly-established institutional arrangements to drive and coordinate socio-ecological change (Ramiller and Schmidt 2018).…”

Human activity has modified and deteriorated natural ecosystems in ways that reduce resilience and exacerbate environmental and climate problems. Physical measures to protect, manage and restore these ecosystems that also address societal challenges in sustainable ways and bring biodiversity benefits are sometimes referred to as “nature-based solutions” (NBS). For example, reducing deforestation and restoring forests is a major opportunity for climate mitigation, while protecting or restoring coastal habitats can mitigate damage to coastal areas from natural hazard events, in addition to potentially providing co-benefits related to livelihood, recreation, and biodiversity. There is now an impetus to shift towards greater deployment of nature-based solutions. Not only do they offer an alternative to conventional fossil fuel-based or hard infrastructure solutions but, if implemented correctly, they also hold great promise for achieving multiple goals, benefits and synergies. These include climate mitigation and resilience; nature and biodiversity protection; and economic and social gains. 2020 saw an explosion in publications about NBS, which have contributed to filling many of the knowledge gaps that existed around their effectiveness and factors for their success. These publications have also highlighted the knowledge gaps that remain and have revealed a lack of critical reflection on the social and economic sustainability aspects of NBS. Building on these gaps, we decided to launch this mini-series of four briefs to provoke a more nuanced discussion that highlights not only the potential benefits, but also the potential risks and trade-offs of NBS. The purpose is not to downplay the importance of NBS for biodiversity, ecosystems, and coastal mitigation and adaptation, but to ensure that we establish a dialogue about ways to overcome these challenges while leaving no one behind.

“…NBS worldwide are inadequately scaled to achieve the desired impact (Perring et al 2018). A common understanding or conceptual framework of what scaling means for NBS, and possible trade-offs, is lacking (Fastenrath et al 2020). Barriers to scaling of NBS include complex combinations of inadequate human and financial resources, insufficient knowledge and technical know-how, divergent motivations and goals, weak institutional capacities and governance structures, insufficient coordination and cooperation, and inadequate policies, laws and regulations (Murcia et al 2016;Ershad Sarabi et al 2019).…”

Scaled up planning and implementation of nature-based solutions requires better understanding of broad characteristics (typologies) of the current governance and financing landscape, collaborative approaches amidst local complexities, and factors of scalability. An inventory was compiled of water-related ecological infrastructure intervention projects in two river systems in South Africa, incorporating actor, environmental, social, and financial dimensions and benefits. Qualitative participatory analysis revealed eight typologies. Post-hoc classification analysis determined similarities and/or unique characteristics of seven quantitative typologies. Key characterising factors included the complexity/size of financial flows, complexity of partnership/governance arrangements, mandates/goals of actors, type of ecological infrastructure, trade-offs in investment in ecological/built infrastructure, and the model used for social benefits. Identified scalable typologies offer structures suited to increased investment, with other typologies offering specialised local value. A range of ecological infrastructure intervention typologies with differing biophysical and socioeconomic outcomes provide choices for investors with specific goals, and benefits to landscape actors.
