The nature-based solutions (NBS) were assessed as scenarios from experience of urban storm drainage and sewerage systems based on practices that improve urban water management through modelling using urban stormwater management model (SWMM). The model has been applied in a typical urban environment in the second city in Botswana, the City of Francistown, which has a population of more than one hundred thousand. By considering the 2-yr and 10-year storm events in a calibrated SWMM, NBS scenarios from a mix of low impact and drainage measures were considered. The considered NBS scenarios were used to determine their effectiveness in terms of reducing and controlling peak runoff, flood volumes, infiltration and evapotranspiration in the study area, which are vital in assessing the opportunity and challenge for sustainable management of water resources and associated tradeoff of investments in the urban contexts. The study demonstrates the usefulness of implementing effective measures for achieving NBS in urban context and possibility of outscaling at basin and regional levels.展开更多

PCS has major consequences for the individuals diagnosed, and society as a whole. Objective: The objective of the pilot study was to investigate whether a nature-based therapeutic (NBT) intervention would be suitable for ameliorating the symptoms experienced by people with PCS, especially mental fatigue. Method: Eight participants diagnosed with PCS took part in a NBT programme, which consisted of weekly two-hour sessions over the course of eight weeks. The participants’ level of mental fatigue was measured on the Mental Fatigue Scale (MFS) before and after the intervention. An analogue scale inspired by the EuroQol-visual analogue scales (EQ-VAS) was used to measure immediate self-perceived feeling of health/ well-being before and after individual sessions. A semi-structured interview was held with each participant after the intervention. The interviews and logbooks were analysed through content analysis, which entails several steps in a spiral-like process, from reading and re-reading the transcripts to forming units of meaning, which were then grouped into sub-categories and categories for further analysis. Result: The MFS showed a significant decrease in mental fatigue and large effect size. The participants’ self-assessed health/ well-being on the analogue scale showed an increase from the beginning to the end of each session. The analysis of the interviews revealed that the participants experienced the sensory stimuli and exercises in the natural environment as motivating and meaningful, even when they were challenging. Further, they found the psycho-educational aspects transferable to everyday life. Conclusion: The results support that NBT can have potential in the rehabilitation of PCS, by lowering mental fatigue and improving health and well-being. The NBT was further found to be experienced as enjoyable and motivating with good transferability to everyday life.展开更多

The basic research aims at achieving the balance between the conflicting impacts when the buildings with their infrastructure and water-green surrounding area are in such correlation that it fulfils acceptable living and heating standards and reduces the use of fossil fuels for cooling the urban areas (buildings). By implementing the remote detection it is possible to analyze and quantify the impact of over-building on the temperature rise in urban areas as well as the disturbance of the heating comfort and the increased demand for additional cooling. Now it is possible to create virtual models that will incorporate this newly-added urban vegetation into urban plans, depending on the evaporation potential that will affect the microclimate of the urban area. Such natural cooling can be measured and adapted and hence aimed at a potential decrease in areas with UHI emissions [2]. Suitable greenery in the summer season can be a useful improvement which concurrently enables and complements several cooling mechanisms—evaporative cooling and evapotranspiration, i.e. natural cooling systems. The remote detection shall establish and map the “healthy” and “unhealthy” greenery zones—that is the vegetation zones with the highest evaporative potential with the “cooling by evaporation” effect and also, by implementing the urban prediction model, it shall propose green infrastructure corridors aimed at a potential decrease in the Urban Heat Island Emission.展开更多

文摘Rotational grazing is considered as one of the nature-based solutions(NbS)to grassland protection by natural scientists.However,its effects on improving grassland quality are still unclear when it is adopted by herders.Using a householdlevel panel data from field survey in two main pastoral provinces of China,empirical results from fixed-effect model and instrumental approach show that rotational grazing practices have insignificant short-term effects on grassland quality,but have positive long-term effects.In addition,rotational grazing practices can improve grassland quality when villages invest public infrastructure or herders have private supporting measures for more efficiency livestock production.Further analysis shows that herders adopting rotational grazing have higher grazing intensity,higher supplementary intensity and more livestock-house-feeding days,which indicate herders can utilize more efficient livestock management without increasing pressure on natural grassland.We also find that herders with pastoral income are more likely to adopt rotational grazing practice.These insightful findings offer policy implications on promoting grassroot NbS for ecosystem protection and resource utilization in developing pastoral countries.

By considering the 2-yr and 10-year storm events in a calibrated SWMM, NBS scenarios from a mix of low impact and drainage measures were considered. The considered NBS scenarios were used to determine their effectiveness in terms of reducing and controlling peak runoff, flood volumes, infiltration and evapotranspiration in the study area, which are vital in assessing the opportunity and challenge for sustainable management of water resources and associated tradeoff of investments in the urban contexts. The study demonstrates the usefulness of implementing effective measures for achieving NBS in urban context and possibility of outscaling at basin and regional levels.
文摘Background: Approximately 10% - 15% of people diagnosed with a concussion develop post-concussion syndrome (PCS), in which mental fatigue is a dominating symptom. PCS has major consequences for the individuals diagnosed, and society as a whole. Objective: The objective of the pilot study was to investigate whether a nature-based therapeutic (NBT) intervention would be suitable for ameliorating the symptoms experienced by people with PCS, especially mental fatigue. Method: Eight participants diagnosed with PCS took part in a NBT programme, which consisted of weekly two-hour sessions over the course of eight weeks. The participants’ level of mental fatigue was measured on the Mental Fatigue Scale (MFS) before and after the intervention. An analogue scale inspired by the EuroQol-visual analogue scales (EQ-VAS) was used to measure immediate self-perceived feeling of health/ well-being before and after individual sessions. A semi-structured interview was held with each participant after the intervention. The interviews and logbooks were analysed through content analysis, which entails several steps in a spiral-like process, from reading and re-reading the transcripts to forming units of meaning, which were then grouped into sub-categories and categories for further analysis. Result: The MFS showed a significant decrease in mental fatigue and large effect size. The participants’ self-assessed health/ well-being on the analogue scale showed an increase from the beginning to the end of each session. The analysis of the interviews revealed that the participants experienced the sensory stimuli and exercises in the natural environment as motivating and meaningful, even when they were challenging. Further, they found the psycho-educational aspects transferable to everyday life. Conclusion: The results support that NBT can have potential in the rehabilitation of PCS, by lowering mental fatigue and improving health and well-being. The NBT was further found to be experienced as enjoyable and motivating with good transferability to everyday life.
文摘Despite prevailing interests,no rigorous research has been conducted to examine the role of nature in natural-hazard preparedness.This systematic review aimed to describe how nature can reduce the impacts of natural hazards during the preparedness stage.The study focuses on the land,water,and air systems and on three types of stakeholders:international organizations,developed countries,and developing countries.Further,it provides supplementary strategies,such as immediate actions,local engagement,and research and development,that the stakeholders should apply to enhance their nature-based natural-hazard preparedness.We suggest integrating costs and benefits analysis,local culture,societal challenges,and environmental justice into the implementation of nature-based solutions.Finally,this review outlines the framework of nature-based natural-hazard preparedness by discussing the relationship between nature and society.

文摘The rapid pace of urbanization has led to the exacerbation of issues such as urban flooding,air pollution,and ecological degradation.In this context,the natural regulatory functions of urban open green spaces have emerged as crucial elements in mitigating these challenges.From the perspective of nature-based solutions(NBS),Chulalongkorn Centennial Park serves as a case study for in-depth analysis.The objective is to investigate the role of urban open green spaces in environmental regulation.Furthermore,the research proposes scientific strategies for planning,design,and construction to enhance the ecological service functions and natural regulatory capacities of such spaces.
文摘After an international contest announced by the City of Abu Dhabi “Cool Abu Dhabi Challenge”<sup>1</sup> and the article published as a digest of a paper titled A Nature-based Solution [1], the decision has been made to take part in improving thermal comfort in public spaces by mitigating the impact of the effect of Urban Heat Islands (UHI)<sup>2</sup> in the city of the Belgrade. The basic research aims at achieving the balance between the conflicting impacts when the buildings with their infrastructure and water-green surrounding area are in such correlation that it fulfils acceptable living and heating standards and reduces the use of fossil fuels for cooling the urban areas (buildings). By implementing the remote detection it is possible to analyze and quantify the impact of over-building on the temperature rise in urban areas as well as the disturbance of the heating comfort and the increased demand for additional cooling. Now it is possible to create virtual models that will incorporate this newly-added urban vegetation into urban plans, depending on the evaporation potential that will affect the microclimate of the urban area. Such natural cooling can be measured and adapted and hence aimed at a potential decrease in areas with UHI emissions [2]. Suitable greenery in the summer season can be a useful improvement which concurrently enables and complements several cooling mechanisms—evaporative cooling and evapotranspiration, i.e. natural cooling systems. The remote detection shall establish and map the “healthy” and “unhealthy” greenery zones—that is the vegetation zones with the highest evaporative potential with the “cooling by evaporation” effect and also, by implementing the urban prediction model, it shall propose green infrastructure corridors aimed at a potential decrease in the Urban Heat Island Emission.

文摘Awe,as a positive emotional experience,is recognized for its role in facilitating tourists’pro-environmental behavior(TPEB).However,despite its significance,awe has received minimal attention in tourism-related research.This research introduces an expanded model of the theory of planned behavior(TPB)that integrates awe into the rational-oriented TPB framework to examine its impact on TPEB.We collected data at the Mount Huangshan scenic spot in China and employed structural equation modeling for data analysis.Findings suggest that the extended TPB model,which incorporates the emotion of awe,outperforms the original TPB model in predicting TPEB.Awe experienced in nature-based destinations is mainly influenced by the perception of the natural environment(PNE)and significantly predicts TPEB.Study findings offer an integrated framework combining emotional and rational perspectives to understand the factors driving TPEB in nature-based tourism.Furthermore,the study aims to establish connections between the psychological experience of awe and the philosophical perspective of the sublime.Importantly,our findings provide compelling evidence supporting the role of nature-based tourism as an effective model to facilitate tourists’environmental attitudes,emotions,and behaviors.Finally,the implications for practice are discussed.
文摘As the impacts of climate change intensify and ecological degradation accelerates,the inadequacies of carbon-centric and concrete-dependent infrastructure have become increasingly evident.This article introduces the“Sponge Planet”paradigm-a transformative,landscape-based framework for climate adaptation and ecological restoration grounded in hydrological logic and nature-based urbanism.Synthesizing insights from decades of research and implementation across more than 600 projects worldwide,the work critiques the systemic failures of gray infrastructure,highlighting its historical,cultural,and material dissonance with ecological principles.In contrast,the Sponge Planet model is structured around three foundational strategies-retaining,slowing,and embracing water-thereby reimagining urban and rural environments as porous,adaptive systems capable of mitigating floods,droughts,sea-level rise,and urban heat.Through case studies from China,Thailand,and other countries and regions,the article illustrates how modular design,local materiality,and GIS-based precision can be employed to construct deep forms of ecological infrastructure.It ultimately advances a planetary design framework that integrates scientific knowledge,cultural heritage,and landscape architecture to restore Earth’s regenerative capacity and promote scalable resilience in the face of climate crises.
文摘Coastal erosion poses a major threat to low-elevation coastal zones such as Saint-Louis in Senegal,where rapid shoreline retreat has led to community displacement and infrastructure degradation.To address this challenge,naturebased solutions(NbS)have been deployed within the Saint-Louis Marine Protected Area(MPA),notably the installation of“Typhavelles”structures made from Typha australis designed to promote dune formation and reduce erosion.This study assesses the effectiveness of“Typhavelles”using field data collected from 2019 to 2022,complemented by diachronic satellite imagery analysis.Results indicate a notable increase in beach width and dune development across the majority of monitored profiles.Shoreline change analysis reveals a dramatic shift from severe erosion(up to−94.5 m/year between 2017 and 2019)to significant accretion,reaching up to+136 m/year during the 2019-2021 period following the installation of the“Typhavelles”.These findings demonstrate that“Typhavelles”are effective in trapping sediment and stabilizing the coastline.However,their long-term viability may be compromised by sea level rise,sediment supply limitations,maintenance needs,and material biodegradation.The study highlights the promise of bio-inspired NbS for coastal protection and recommends enhancing“Typhavelles”durability through protective treatments to support broader replication in similar vulnerable coastal zones.

文摘Background In the climate change context,nature-based solution(NBS)is considered one of the effective tools to increase the resilience of socio-ecological system.The concept coincides with the government’s attempts of afforestation and reforestation programs that have been going on for 60 years in Bangladesh.This study,therefore,envisaged understanding how NBS(mangrove afforestation and reforestation)works to promote climate change resilience through the synthetization of remote sensing-based big earth data,statistical tools,and models.The study took the entire coast of Bangladesh except for Sundarbans Reserve Forest and rolled back to 1962 to work on 60 years’time series data.Declassified CORONA satellite imagery along with Landsat satellite imagery was used,which is the first-ever attempt in the remote sensing-based ecosystem work in Bangladesh.Results The study’s main innovation is to spatially establish the effectiveness of the NBS.The study critically assessed and estimated stable lands and their socio-economic benefits as part of the effectiveness of the NBS.As part of the NBS-derived benefits in the context of climate change,it estimated the sequestrated carbon in mangrove forests.A significant positive relationship was observed between the increase of mangroves and stable lands.Near about 448,011 ha of agricultural land was stabilized due to the NBS intervention whose economic value is 18,837 million USD.In addition,29,755.71 kt of carbon have been sequestrated due to NBS program.Conclusions The concept of NBS is still in the development stage and very little or no work has been done so far in measuring and labeling the effectiveness of the NBS.Therefore,our study can innovatively contribute to the scientific community to show the effectiveness of the NBS in three domains(social,economic and ecological)in the changing climatic scenario.

文摘Background:With elderly people comprising a growing share of the population,landscape planners need to consider their specific requirements to enhance the opportunities for them to engage in nature-based recreation(NBR).However,few studies have spatially assessed the recreation potential,demand,and opportunities for elderly people in cities.Thus,this paper aimed to spatially model and investigate the NBR opportunities for and demand of elderly people in urban areas.A spatial framework based on the ESTIMAP recreation model was developed,considering special factors to better reflect elderly people’s preferences regarding NBR at the city scale.In particular,NBR opportunities were assessed considering landscape aesthetics,various types of facilities,and proximity.The street network was used to understand elderly people’s walking behaviours regarding green spaces and related facilities.Results:A case study in Hannover,Germany,demonstrated the applicability of the proposed method.The results illustrate the spatial heterogeneity of recreation options for the elderly.Only parts of Hannover’s green spaces offer high recreation opportunities for elderly people.Many of the existing green spaces lack diverse landscape compo-nents and sufficient supply of facilities,resulting in a compromise to aesthetics and recreational opportunities.Conclusions:The proposed method contributes to research on spatial planning and environmental justice by incorporating vulnerable groups’preferences and needs in spatially assessing NBR.The planning implications highlight pocket gardens and greenways connecting communities and parks as development opportunities in the city.

文摘Nature-based solutions(NBS)are seen as a promising adaptation measure that sustainably deals with diverse societal challenges,while simultaneously delivering multiple benefits.Nature-based solutions have been highlighted as a resilient and sustainable means of mitigating floods and other hazards globally.This study examined diverging conceptualizations of NBS,as well as the attitudinal(for example,emotions and beliefs)and contextual(for example,legal and political aspects)barriers and drivers of NBS for flood risks in South Korea.Semistructured interviews were conducted with 11 experts and focused on the topic of flood risk measures and NBS case studies.The analysis found 11 barriers and five drivers in the attitudinal domain,and 13 barriers and two drivers in the contextual domain.Most experts see direct monetary benefits as an important attitudinal factor for the public.Meanwhile,the cost-effectiveness of NBS and their capacity to cope with flood risks were deemed influential factors that could lead decision makers to opt for NBS.Among the contextual factors,insufficient systems to integrate NBS in practice and the ideologicalization of NBS policy were found to be peculiar barriers,which hinder consistent realization of initiatives and a long-term national plan for NBS.Understanding the barriers and drivers related to the mainstreaming of NBS is critical if we are to make the most of such solutions for society and nature.It is also essential that we have a shared definition,expectation,and vision of NBS.

文摘Anammox bacteria in constructed wetlands(CWs)play pivotal role in sustainable nitrogen transformation,yet existing studies lack comprehensive analysis of environmental gradients and microbial interactions,both key factors in anammox bacteria enrichment.This study investigated the mechanisms driving anammox bacteria enrichment in lab-scale simulated CWs treating high-nitrogen wastewater,focusing on bacterial community re-sponses across wetland layers with various strategies,including continuous up-flow influent,nitrogen loading increase,effluent recirculation,intermittent influent,and anammox bacteria inoculation.Results showed that total relative and absolute abundances of anammox bacteria ranged from 0.77%to 12.50%and from 0.13 to 6.46×10^(7) copies/g,respectively.Dissolved oxygen and pH had significant positive correlations with the absolute abundance of anammox bacteria,while organic matter and nitrate negatively impacted their relative abundance.Permutational multivariate analysis of variance indicated that spatial heterogeneity explained more variation in anammox bacteria abundance(43.44%)compared to operational strategies(8.58%).In terms of microbial interactions,60 dominant species exhibited potential correlations with anammox bacteria,comprising 170 interactions(105 positive and 65 negative),which suggested that anammox bacteria generally foster cooperative relationships with dominant bacteria.Notably,significant interspecies interactions were observed between Candidatus Kuenenia(dominant anammox bacteria in CWs)and species within the genera Chitinivibrio-nia and Anaerolineaceae,suggesting that microbial interactions primarily manifest as indirect facilitative effects rather than direct mutualistic relationships.Given that the Normalized Stochasticity Ratio in CWs were<50%,this study inferred that environmental gradients have greater influence on anammox bacteria than microbial interactions.

文摘China has executed large-scale ecological restoration projects(ERPs)to meet the goals of environmental pro-tection and economic development.Yet,the integrated outcomes of these projects on the biodiversity-eco-environment-society dimensions remain unclear,but when available could be insightful for adaptation and ad-justments,particularly in this United Nations Decade on Ecosystem Restoration(2021-2030).Based on multi-source data,we identified the categories and quantities of large-scale ERP implementation in the county-level.By comparing the time-series multiple factors of implemented vs unimplemented counties,we quantify the con-tributions and compare the relative effects of up to six different ERPs.Combining random forest,spatial autocor-relation,and network analysis,we explore the key factors that affect the contributions of ERPs.Here,we show that the triple dimensions in the low ERP group(regions implementing 0-2 projects)produced better outcomes than the high ERP group(regions implementing 3-5 projects)in relatively developed regions,while the high ERP group has more gains than the low ERP group in relatively less-developed regions.Notably,regional character-istics and different social assets mediate the ERP contributions,while human capital and financial capital have important roles.Overall,the ERPs generated positive contributions and could increase the network stability of multi-dimensions in relatively less-developed regions,but it may lead to imbalances in some factors(i.e.,mam-mal species conservation,and human capital).To continue to minimize the negative effects from past,and to improve the returns of ERP policy and investments,more timely and adaptive management of ERPs are needed,especially in relatively less-developed regions.

文摘Shoreline erosion has been a pernicious problem facing many countries around the world.It causes the degradation and vulnerability of coastal eco-environments,and imposes considerable pressures upon coastal economic,social developments in the context of climate change and sea-level rising.The muddy coast of the abandoned Yellow River delta at Binhai,Jiangsu Province,China has experienced chronic erosion since 1855 when the Yellow River avulsed to north China.A variety of hard structures,that is,seawall,groin,jetty,breakwater,and so forth were emplaced and reinforced to withstand the shoreline retreat and concomitant beach loss.These engineering solutions have been proved unsuccessful or ineffective in their objectives.An overview is presented on the multi-decadal defense endeavors with technical lessons and management implications learnt.A SHIAA(site-specific,holistic,integrative,adaptive,affordable)tenet is put forward to achieve the sustainability in a coastal erosion mitigation scheme.The merit and limitation of nature-based solutions(NBS)applied in coastal protection is further discussed.

文摘The Jabodetabek Metropolitan Area(JMA),Indonesia’s largest urban agglomeration,faces severe challenges due to rapid population growth and environmental degradation.Expanding urban areas has led to a reduction in green spaces,damaging ecosystem services,and exacerbating urban heat island effect,soil erosion,and flood risk.Therefore,this study identified key ecosystem service indicators,including Urban Heat Mitigation(UHM),Sediment Retention(SR),and Flood Risk Mitigation(FRM),and defined the spatial pattern of ecosystem services and its management zones in the JMA in 2024.Spatial data and ecosystem service indicators were analyzed using the Integrated Valuation of Ecosystem Services and Trade-offs(InVEST)and spatial clustering analysis tool(e.g.,Rustiadi’s Quantitative Zoning Method(RQZM)Ⅱ),and the results served as the basis for formulating strategic recommendations.This study highlighted significant regional disparities.Jakarta,Tangerang Regency,Bekasi Regency,Depok City,Tangerang City,South Tangerang City,and Bekasi City experienced the increase of urban heat effect and flood risk due to dense infrastructure and limited green spaces.Conversely,southern peri-urban areas of Bogor Regency demonstrated higher ecological capacities,particularly in water infiltration and temperature regulation,but remained vulnerable to soil erosion due to urban expansion.The results underscored the critical imbalance between growing urban demands and the diminishing capacity of peri-urban areas to supply ecosystem services,which is driven by the transformation of green spaces into built-up areas.To address these challenges,this study proposed the Nature-Based Solutions(NBS)by emphasizing forested area conservation in the southern region of the JMA,natural landscape restoration and rehabilitation in the central region,and a hybrid of natural and artificial ecosystem creation in the northern region.
