As natural disasters are induced by geodynamic activities or abnormal changes in the environment, geological hazards tend to wreak havoc on environment and human society. Recently, dramatic increase volume of various types Earth observation 'big data' from multiple sources, rapid development deep learning as a state-of-the-art data analysis tool, have enabled novel advances hazard analysis, with ultimate aim mitigate devastation associated these hazards. Motivated numerous applications, this paper presents an overview utilization for analysis. First, six commonly available sources described, e.g., unmanned aerial vehicles, satellite platforms, in-situ monitoring systems. Second, background typical models introduced, such convolutional neural networks recurrent networks. Third, focusing hazards, i.e., landslides, debris flows, rockfalls, avalanches, earthquakes, volcanoes, applications reviewed, common application paradigms summarized. Finally, challenges opportunities highlighted, inspire further related research.

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.

<p>The sustainability of life on Earth is under increasing threat due to human-induced climate change. This perilous change in the Earth's caused by increases carbon dioxide and other greenhouse gases atmosphere, primarily emissions associated with burning fossil fuels. Over next two three decades, effects change, such as heatwaves, wildfires, droughts, storms, floods, are expected worsen, posing greater risks human health global stability. These trends call for implementation mitigation adaptation strategies. Pollution environmental degradation exacerbate existing problems make people nature more susceptible In this review, we examine current state from different perspectives.

The combination of urbanization and global warming leads to urban overheating compounds the frequency intensity extreme heat events due climate change. Yet, risk can be mitigated by green-blue-grey infrastructure (GBGI), such as parks, wetlands, engineered greening, which have potential effectively reduce summer air temperatures. Despite many reviews, evidence bases on quantified GBGI cooling benefits remains partial practical recommendations for implementation are unclear. This systematic literature review synthesizes base mitigation related co-benefits, identifies knowledge gaps, proposes their maximize benefits. After screening 27,486 papers, 202 were reviewed, based 51 types categorized under 10 main divisions. Certain (green walls, street trees) been well researched capabilities. However, several other received negligible (zoological garden, golf course, estuary) or minimal (private allotment) attention. most efficient was observed in botanical gardens (5.0 ± 3.5°C), wetlands (4.9 3.2°C), green walls (4.1 4.2°C), trees (3.8 3.1°C), vegetated balconies 2.7°C). Under changing conditions (2070-2100) with consideration RCP8.5, there is a shift subtypes, either within same zone (e.g., Dfa Dfb Cfb Cfa) across zones [continental warm-summer humid] BSk [dry, cold semi-arid] Cwa [temperate] Am [tropical]). These shifts may result lower efficiency current future. Given importance multiple services, it crucial balance functionality, performance, co-benefits when planning future GBGI. inventory assist policymakers planners prioritizing effective interventions overheating, filling research promoting community resilience.

Cities, and in particular those coastal low-lying areas, are becoming increasingly susceptible to climate change, the impact of which is worsened by tendency for population concentration these areas. Therefore, comprehensive early warning systems necessary minimize harm from extreme events on communities. Ideally, such a system would allow all stakeholders acquire accurate up-to-date information respond effectively. This paper presents systematic review that highlights significance, potential, future directions 3D city modelling, systems, digital twins creation technology building resilience through effective management smart cities. In total, 68 papers were identified PRISMA approach. A total 37 case studies included, among (n = 10) define framework twin technology, 14) involve design virtual models, 13) entail generation alerts using real-time sensor data. concludes bidirectional flow data between model real physical environment an emerging concept enhancing resilience.

Опубликована: Янв. 10, 2024

Droughts are the most expensive climate disasters as they leave long-term and chronic impacts on ecosystem, agriculture, human society. The intensity, frequency, duration of drought events have increased over years expected to worsen in future a regional planetary/global scale. Nature-based solutions (NBS) such wetland floodplain restorations, green infrastructures, rainwater harvesting, etc., highlighted effective cope with these events. While role NBS coping other disasters, floods, has been extensively studied, there lack comprehensive review targeting drought. following paper provides unique critical state-of-the-art literature individual drought-related around world, Europe, particularly Belgium, assesses differences between applied globally Flanders. An extensive was conducted systematically analyze NBS, listing type, location, status implementation, possible recommendations proposed optimize applications. Finally, comparison is made small- large-scale applications NBS. By analyzing all aspects, especially level effectiveness recommendations, insight gained into potential improvements. research indicated scientific publications, Belgium. Hence, grey also included review. Only four papers quantitative assessment regarding global level, stating positive impact groundwater recharge. In contrast, at country levels, performance not quantified. number implementations low, where landscape- or watershed-scale holistic approaches mitigation still scarce. Some successfully implemented projects only very local long realization time, two aspects that limit achieving visible larger Among many wetlands recognized highly but degraded lost despite their significant restoration potential. A common evaluation framework shall be followed, which gives policymakers clear view different investment options. Furthermore, more collaborative approach recommended globally, including stakeholder groups, specific attention communities. To conclude, should increase evidence base implementation drought-mitigating
