Although many governments, financial institutions, and corporations are embracing nature-based solutions as part of their sustainability net-zero carbon strategies, some nations, Indigenous peoples, local community groups, grassroots organizations have rejected this term. This pushback is fueled by (i) critical uncertainties about when, where, how, for whom effective (ii) controversies surrounding misuse in greenwashing, violations human rights, threats to biodiversity. To clarify how the scientific can help address these issues, I provide an overview recent research on benefits limits solutions, including they compare with technological approaches, highlight areas future research.

Nature-based solutions (NBS) for hydro-meteorological risks (HMRs) reduction and management are becoming increasingly popular, but challenges such as the lack of well-recognised standard methodologies to evaluate their performance upscale implementation remain. We systematically current state-of-the art on models tools that utilised optimum allocation, design efficiency evaluation NBS five HMRs (flooding, droughts, heatwaves, landslides, storm surges coastal erosion). found methods assess complex issue cost-benefits analysis still in development stage they have only been implemented through developed other purposes fluid dynamics micro catchment scale contexts.

Assessment of urban flood vulnerability using the social-ecological-technological systems framework in six US cities

Sustainable Cities and Society, Год журнала: 2021, Номер 68, С. 102786 - 102786

Опубликована: Фев. 21, 2021

As urban populations continue to grow through the 21st century, more people are projected be at risk of exposure climate change-induced extreme events. To investigate complexity floods, this study applied an interlinked social-ecological-technological systems (SETS) vulnerability framework by developing flood index for six US cities. Indicators were selected reflect and illustrate exposure, sensitivity, adaptive capacity flooding each three domains SETS. We quantified 18 indicators normalized them cities' 500-yr floodplain area census block group level. Clusters vulnerable areas identified differently SETS domain, some floods in than one domain. Results provided support decision-making reducing risks flooding, considering social, ecological, technological as well hotspots where multiple sources coexist. The spatially explicit can transferred other regions facing challenging types environmental hazards. Mapping helps reveal intersections complex interactions inform policy-making building resilient cities face events change impacts.

Uptake and implementation of Nature-Based Solutions: An analysis of barriers using Interpretive Structural Modeling

Journal of Environmental Management, Год журнала: 2020, Номер 270, С. 110749 - 110749

Опубликована: Июнь 12, 2020

Cities increasingly have to find innovative ways address challenges arising from climate change and urbanization. Nature-based solutions (NBS) been gaining attention as multifunctional that may help cities these challenges. However, the adoption implementation of limited due various barriers. This study aims identify a taxonomy dominant barriers uptake NBS their relationships. Fifteen are identified literature expert interviews then ranked through questionnaire. Interpretive Structural Modeling (ISM) serves mutual interdependencies among barriers, which results in structural model six levels. Subsequently, Cross-impact matrix multiplication applied classification (MICMAC analysis) is used classify into four categories. The suggest political, institutional knowledge-related most NBS. intend apply can draw on findings, especially by more effectively prioritizing managing actions.

The modelling and management of flood risk in urban areas are increasingly recognized as global challenges. complexity these issues is a consequence the existence several distinct sources risk, including not only fluvial, tidal coastal flooding, but also exposure to runoff local drainage failure, various strategies that can be proposed. high degree vulnerability characterizes such expected increase future due effects climate change, growth population living cities, densification. An increasing awareness socio-economic losses environmental impact flooding clearly reflected recent expansion number studies related sometimes within framework adaptation change. goal current paper provide general review advances flood-risk management, while exploring perspectives fields research.

Natural hazards are processes that serve as triggers for natural disasters. can be classified into six categories. Geophysical or geological relate to movement in solid earth. Their examples include earthquakes and volcanic activity. Hydrological the of water floods, landslides, wave action. Meteorological storms, extreme temperatures, fog. Climatological increasingly related climate change droughts wildfires. Biological caused by exposure living organisms and/or their toxic substances. The COVID-19 virus is an example a biological hazard. Extraterrestrial asteroids, meteoroids, comets they pass near earth strike In addition local damage, inter planetary conditions affect Earth’s magnetosphere, ionosphere, thermosphere.

Towards a smart water city: A comprehensive review of applications, data requirements, and communication technologies for integrated management

Sustainable Cities and Society, Год журнала: 2021, Номер 76, С. 103442 - 103442

Опубликована: Окт. 19, 2021

Smart cities are an innovate concept for managing urban to enhance sustainability and increase quality of life citizens. Although water infrastructure (UWI) performs important functions in a city (e.g., supply drinking water), information communication technologies (ICT) system-wide management network-based UWI not yet widely deployed. Therefore, this review summarises first both existing potential applications related UWI, characterised by different spatial temporal resolution measurement control data. Second, comprehensive analysis ICT is provided, which extended with exemplary the field. The reveals that coordination between intended application usable technology required realise efficient monitoring network field networks. To overcome limitation, detailed framework developed, can be used researcher, operators, stakeholder identify suitable or determine possible system. Following, applicability demonstrated selected examples. As also indicates, integrated approach towards smart requires combination satisfy all specifications.
