Frontiers in Environmental Science, Journal Year: 2022, Volume and Issue: 10

Published: June 29, 2022

Momentum for sustainable and climate resilience solutions coastal protection are growing globally given the pressing need to prevent further loss of biodiversity ecosystems while meeting change adaptation mitigation goals. Nature-Based Solutions (NbS) represent an opportunity align environmental goals, at a time strained budgets in global context when short-term needs may run counter long-term In Europe, NbS fit mandates major EU policies by restoring enhancing climate-resilience carbon sequestration. Previous studies have compiled scientific evidence about hydro-meteorological hazards use NbS. However, their implementation scale is still lacking. As knowledge experience with natural increases, it becomes more important draw lessons learned insights replicating scaling up NbS, especially areas where limited compared other environments. This study analyzed case across European estuarine key lessons, understand better current status implementation, identify challenges gaps. From total 59 associated flooding, erosion loss, results show increase since 1990s, but most rapidly between 2005 2015. Most hybrid employing wetlands, predominantly located United Kingdom (UK) Netherlands. Funding largely from public sources, rarely come single or private source. Three-quarters reported monitoring activities, than half did not disclose quantitative related effectiveness against flooding and/or erosion. The improve defenses was indicated as main motivation over traditional structures, sustainability mentioned additional reason. Although variety co-benefits identified, clearer descriptions enhanced details such information required. There tools strategies expand sharing enable replication successful cases areas.

Published: Sept. 28, 2022

Flooding is one of the most prevalent types natural catastrophes, and it can cause extensive damage to infrastructure environment. The primary method flood risk management susceptibility mapping (FSM), which provides a quantitative assessment region’s vulnerability flooding. objective this study develop new ensemble models for FSM by integrating metaheuristic algorithms, such as genetic algorithms (GA), particle swarm optimization (PSO), harmony search (HS), with decision table classifier (DTB). proposed were applied in province Sulaymaniyah, Iraq. Sentinel-1 synthetic aperture radar (SAR) data satellite images used monitoring (on 27 July 2019), 160 occurrence locations prepared modeling. For training validation datasets, coupled 1 flood-influencing parameters (slope, altitude, aspect, plan curvature, distance from rivers, land cover, geology, topographic wetness index (TWI), stream power (SPI), rainfall, normalized difference vegetation (NDVI)). certainty factor (CF) approach was determine spatial association between effective floods, resulting weights employed modeling inputs. According pairwise consistency technique, NDVI altitude are significant factors area under receiver operating characteristic (AUROC) curve evaluate accuracy effectiveness models. DTB-GA model found be accurate (AUC = 0.889), followed DTB-PSO 0.844) DTB-HS 0.812). This research’s hybrid provide reliable estimate risk, maps early-warning control systems.

Quantifying the influence of nature-based solutions on building cooling and heating energy demand: A climate specific review

Renewable and Sustainable Energy Reviews, Journal Year: 2023, Volume and Issue: 186, P. 113660 - 113660

Published: Aug. 22, 2023

Implementing Nature-Based Solutions (NBS) is a promising way to reduce building energy demand and facilitates the achievement of United Nations Sustainable Development Goal 7, as they provide shading, evapotranspiration cooling other influences on buildings. Although this field has attracted much attention, uncertainty persists regarding potential different NBS types impact in climate conditions. To clarify uncertainty, 101 papers were studied based Web Science Scopus databases. The current status analysis explored development state field. Building performance evaluated reduction heating climates by applying at scale. review revealed that saving varies from 3% 90%, while ranges 0.58% 60%. extent both cases dependent type climate. Notably, some may lead an increase between 5.9% 25% with short mild winters. This found maximizing energy-saving requires comprehensive consideration multiple factors rather than individual factor. Further, most studies have only concentrated few zones, resulting significant differences research depth among categories. Future work should focus neglected fully understand their potential.

Assessing social-ecological vulnerability and risk to coastal flooding: A case study for Prince Edward Island, Canada

International Journal of Disaster Risk Reduction, Journal Year: 2024, Volume and Issue: 106, P. 104450 - 104450

Published: April 4, 2024

Traditional flood risk assessment studies mainly looked at potential exposures and damage to human settlements, without considering the whole social-ecological systems. This study presents a comprehensive hazard characteristics, exposure, vulnerability of systems in coastal areas Prince Edward Island (PEI), Canada. An indicator-based multi-criteria analysis method is adopted estimate index for each local census block affected area under two scenarios (flood climate change with change). The result shows that scores vary along area, higher central western regions. Social elements contribute more compared ecological both urban rural areas. also discussed application results developing appropriate management strategies communities vulnerable ecosystems.

Coastal restoration is often distrusted and, at best, implemented small scales, which hampers its potential for coastal adaptation. Present technical, economic and management barriers stem from sectoral poorly coordinated local interventions, are insufficiently monitored maintained, precluding the upscaling required to build up confidence in ecosystem restoration. The paper posits that there enough knowledge, technology, financial governance capabilities increasing pace scale of restoration, before onset irreversible degradation. We propose a systemic integrates Nature based Solutions (NbS) building blocks, provide climate-resilient services improved biodiversity curb result should be reduction risks decarbonised protection, same time increases blue carbon. discuss enablers adaptation-through-restoration plans, on vulnerable archetypes, such as deltas, estuaries, lagoons bays.

Projection of future hydrometeorological extremes and wetland flood mitigation services with different global warming levels: A case study in the Nenjiang river basin

Ecological Indicators, Journal Year: 2022, Volume and Issue: 140, P. 108987 - 108987

It is common to conceptualize wetlands as a nature-based flood defense for improving basin resilience climate change. Yet, such solution often ignored when projecting or assessing river risk under future To fill this gap, we apply hydrological modeling platform integrating wetland modules 297,000-km2 large in Northeast China different change scenarios. The overarching goal of study predict precipitation extremes and events, explore whether what extent can effectively mitigate the at scale. We first assessed trend extracted from multi-global models (GCMs) found that will increase both RCP4.5 RCP 8.5 increasing extremes, therefore, are projected bring about higher risks with warming levels. Wetlands suppress duration, mean flow, volume, peak by 1.9–10.2%, 4.6–7.1%, 8.7–15.7% 12.5–14.1% basin, respectively. Our attenuate floods 2- 5-year return period great extent. However, mitigation function limited 10-, 20-, 50- return, even failed extreme 100- 200-year return. These findings imply cause cannot be mitigated its wetlands, substantial restoration needed enhance capacity their service order improve basin's risks.
