To bring to fruition the capability of nature-based solutions (NBS) in mitigating hydro-meteorological risks (HMRs) and facilitate their widespread uptake require a consolidated knowledge-base related monitoring methods, efficiency, functioning ecosystem services they provide. We attempt fill this knowledge gap by reviewing compiling existing scientific literature on including ground-based measurements (e.g. gauging stations, wireless sensor network) remote sensing observations from topographic LiDAR, multispectral radar sensors) that have been used and/or can be relevant monitor performance NBS against five HMRs: floods, droughts, heatwaves, landslides, storm surges coastal erosion. These allow mapping impacts specific events. found selection application methods mostly rely particular being monitored, resource availability time, budget, space) type HMRs.

Nature-based solutions addressing the water-energy-food nexus: Review of theoretical concepts and urban case studies

Journal of Cleaner Production, Journal Year: 2022, Volume and Issue: 338, P. 130652 - 130652

Published: Jan. 24, 2022

An increasing world population is projected to increase water, energy and food requirements, three vital resources for humankind. Projected climate change impacts will aggravate water availability, as well flood risks, especially in urban areas. Nature-based solutions (NBS) have been identified key concepts defuse the expected tensions within Water-Energy-Food (W-E-F) nexus due their multiple benefits. In this paper, authors outlined theories concepts, analyzed real-life case studies, discussed potential of NBS address future W-E-F nexus. For purpose, we performed a systematic literature review on that nexus, summarized 19 representative studies identify current knowledge gaps challenges. The quantitative qualitative data was used differentiate discuss direct indirect benefits study further expanded challenges implementation highlighted growing possibilities context circularity planning. It concluded identified, but effects not in-depth. Moreover, indicators are mostly single-purpose multipurpose, required fully characterize holistically. Overall, there need adopt systemic thinking promote multipurpose design NBS.

Nature-Based Solutions and Circularity in Cities

Circular Economy and Sustainability, Journal Year: 2021, Volume and Issue: 1(1), P. 319 - 332

Published: March 17, 2021

Abstract Cities worldwide are facing a number of serious challenges including population growth, resource depletion, climate change, and degradation ecosystems. To cope with these challenges, the transformation our cities into sustainable systems using holistic approach is required. The pathway to this urban transition adopting concept circular economy for management. In way, resources kept reused within city. Nature-based solutions can be implemented tasks, besides circularity, they provide additional benefits urbanites environment in general. This paper describes which related circularity addressed through nature-based solutions. systematic review was developed COST Action CA17133 Circular City that investigates how used progress built environment.

A new evaluation framework for nature-based solutions (NBS) projects based on the application of performance questions and indicators approach

The Science of The Total Environment, Journal Year: 2021, Volume and Issue: 787, P. 147615 - 147615

Published: May 7, 2021

One of the key features nature-based solutions (NBSs) is their high effectiveness and economic resource efficiency in solving problems compared to traditional grey interventions. These aspects, however, have so far attracted little attention literature but should be considered, as evaluation NBS projects before implementation provides an opportunity use them practical tools. This paper aims present a new framework (at stage solution selection) based on application performance questions indicators approach. The consists three main stages: (1) formulation project aim(s), including problem(s) solved, scales expected effects thresholds achieved; (2) elimination that do not fit local conditions setting requirements; (3) examination questions. To consider whole spectrum influencing factors, systematic review was performed indicate concepts related issue effectiveness, stakeholders' participation, policy management capability, efficiency, (4) analysis synergies trade-offs, (5) adaptation conditions, (6) adequate spatial scale (7) long term. In current study around 130 were identified for projects. Regarding impact state knowledge, work contributes discussion conceptual sphere its by introducing multi-perspective standards guidelines selection possible projects, it deals with complexity trade-offs between benefits.

Nature-Based Solutions (NBS) have been proven to effectively mitigate and solve resource depletion climate-related challenges in urban areas. The COST (Cooperation Science Technology) Action CA17133 entitled “Implementing nature-based solutions for building a resourceful circular city” has established seven circularity (UCC) that can be addressed with NBS. This paper presents the outcomes of five elucidation workshops more than 20 European experts from different backgrounds. These international were used examine effectiveness NBS address UCC foster implementation towards water management. A major outcome was identification two most relevant resources areas: ‘Restoring maintaining cycle’ (UCC1) ‘Water waste treatment, recovery, reuse’ (UCC2). s Moreover, significant synergies ‘Nutrient recovery reuse’, ‘Material ‘Food biomass production’, ‘Energy efficiency recovery’, ‘Building system recovery’ identified. Additionally, real-life case studies demonstrate how supporting units contribute UCC. Finally, case-based semi-quantitative assessment presented performed. Most notably, this identifies typically employed enable processes UCC1 UCC2. While current consensus is well by individual NBS, we presently highlight potential combining synergize enabling processes. study new paradigm aims enhance awareness on ability multiple issues.
