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.

Due to increasing population pressure and urbanization, as well global climate change impacts, many coastal river deltas are experiencing increased exposure, vulnerability risks linked natural hazards. Mapping the risk profiles of is critical for developing preparedness, mitigation adaptation policies strategies. Current assessments focus predominantly on social factors, typically, do not systematically incorporate a social-ecological systems perspective, which can lead incomplete assessments. We argue that ecosystem services, link both functions human well-being, be used better characterize mutual dependencies between society environment within assessment frameworks.

Public Acceptance of Nature-Based Solutions for Natural Hazard Risk Reduction: Survey Findings From Three Study Sites in Europe

Climate change is one factor increasing the risk of hydro-meteorological hazards globally. The use nature-based solutions (NbS), and more specifically ecosystem-based disaster reduction measures (Eco-DRR), has become a popular response for that also provides highly-valued co-benefits. Public acceptance particular importance NbS since they often rely on local collaborative implementation, management, monitoring, as well long-term protection against competing societal interests. Although public engagement common goal projects, it rarely carried out with sufficient understanding (de)motivating factors tied to perceptions. Successful collaboration demands consideration attitudes values in relation risk, nature, place. However, existing research does not sufficiently explore these themes together, their interactions, implications NbS.

Nature-based solutions (NbS) contrast with grey infrastructure measures to reduce risk from natural hazards. Using and sustainable (green) or combining green elements (hybrid) can provide important co-benefits beyond reduction. Thanks their flexibility across a range of possible climate change futures, NbS are sometimes referred as 'win-win' 'no-regret' measures. The success associated projects often relies on the public for co-creation, co-implementation, long-term use, monitoring, management. However, relative importance benefits is defined by perceptions underlying values stakeholders potentially divergent interests.

Nature-based solutions for climate change adaptation: A systematic review of systematic reviews

Nature-Based Solutions, Journal Year: 2022, Volume and Issue: 2, P. 100042 - 100042

Published: Nov. 14, 2022

More than 90 systematic reviews have been conducted on the topic of nature-based solutions for climate change adaptation (NBS-CCA). These prior reviews, however, are scattered across more 45 different peer-reviewed journals and gray literature sources, making it difficult to follow all knowledge generated remaining research gaps. In this study, we a review NBS-CCA, with objective mapping analyzing these reviews. We found that most had relatively narrow focuses, typically focusing particular geographic context NBS-CCA (mainly in urban coastal areas) or aspect planning/implementation outcomes assessment policy/governance issues). Fewer focused mountainous areas social financial aspects planning/implementation. The majority relied solely analysis, only 26% including literature, despite large amount variety exists. Notably, no yet attempted comprehensively analyze contexts e.g. through meta-analysis available topic. This would likely require massive multidisciplinary effort, but could be worthy endeavor considering realized need integrate into national/subnational policies various international environmental agreements pertaining (e.g., Paris Agreement) biodiversity conservation Post-2020 Global Biodiversity Framework).

Risk assessment for hurricane-induced pluvial flooding in urban areas using a GIS-based multi-criteria approach: A case study of Hurricane Harvey in Houston, USA

The Science of The Total Environment, Journal Year: 2023, Volume and Issue: 904, P. 166891 - 166891

Published: Sept. 6, 2023

As one of the most destructive nature hazards, hurricane-induced flooding generates serious adverse impacts on populations, infrastructure, and environment globally. In urban areas, complex characteristics such as high population infrastructure densities increase flood disaster risks. Consequently, assessment risks is becoming increasingly important for understanding potential an area proposing risk mitigation strategies. After conducting a comprehensive literature review, this study finds that assessments often overlook ecosystem elements, focusing more social economic aspects. Hence, role ecosystems cannot be fully understood. To address gap, proposes social-ecological systems (SES) framework areas. Based framework, list indicators collected through review provided assessments. A comparative during Hurricane Harvey (2017) in Houston, Texas, USA, carried out using improved analytic hierarchy process (IAHP) weighting method equal indicator weighting. Results are then compared with damage data published by U.S. Federal Emergency Management Agency (FEMA). The analysis identifies western part Houston had highest risks, while center was at lower risk. Comparisons between results from IAHP methods show latter produces broader range areas than former. This also highlights mitigating advocates holistic, Such could utilize proposed but contextualize these to specific area's contexts being investigated.
