A new study published in the International Journal of Mass Emergencies & Disasters proposes an expansion of the traditional hazard event classification system used in disaster research. The article argues that the existing categorization of hazard events as emergencies, disasters, or catastrophes, based on factors like impacts, needs, stakeholder involvement, and management approach, can be further refined by incorporating a second dimension: response duration. The researchers suggest that short-duration and long-duration events within each of the three existing categories (emergencies, disasters, catastrophes) are categorically distinct and require different management approaches. This distinction can help differentiate events like the COVID-19 pandemic and Hurricane Katrina, for example. The proposed change has important implications for emergency management practice and policy, as it encourages a re-evaluation of the types of hazard events considered part of the academic purview of the field. The study aims to contribute to the ongoing efforts by disaster scholars to develop a more robust and nuanced hazard event classification system. #DisasterResearch #HazardClassification #EmergencyManagement #wildfires #fire #disasters #science #management #earth #disasters #naturaldisasters #emergency #flood #climate #climatechange #storm #heat #earthquake #elclubdecomerciantes #evideosecurity #hugihernandez #egreenews #inergency

Last week we celebrated the 182nd Dies Natalis of TU Delft. The Redesigning Delta’s theme couldn’t be more current with the storm surges we experienced at the North Sea and the unusual high discharges in our rivers. In the #Dies lecture, Bas Jonkman argues three things should happen. First, we should shift the focus from the very long term of 2300 to a more realistic planning period of about a century ahead. Secondly, we should account for the uncertainties in various future scenarios. Thirdly, we need to develop future-proof strategies for each region that fit the physical system and the needs and ambitions for regional development. We are educating a next generation of #engineers who are helping to shape a resilient future. Their work really makes an impact for a better society. In the Delta Futures Lab, #students, researchers and practitioners collaborate. After the catastrophic 2021 summer floods in Limburg, they focused on studying the causes and solutions. Check it out in the video below.   The #Journal of Coastal and Riverine Flood Risk just launched a special issue on the 2021 summer #floods in Europe with contributions from different authors highlight #research from Belgium and the Netherlands. Also, lessons for future flood risk management are discussed 👉 https://lnkd.in/gSd2Z468 #Civilengineering #Floodresilience #Floodrisk Gabriela Godlewski Dennis Ronckers

NASANASAEarth ObservatoryEarth In this false-color scene (MODIS bands 7-2-1), areas covered by water appear dark blue. The lighter blues in some of the channels east of the Nile visible in the upper part of the image are signs that soils are still wet even if the ephemeral streams that formed during periods of heavy rain have drained. Vegetation appears green. NOAA’s Global Drought Monitor reports that much of northern Sudan has been exceptionally wet in the past three months. Satellite-based rainfall estimates shared by the IGAD Climate Prediction & Applications Center indicate that many parts of Sudan received tens to hundreds of millimeters of rain during the last three weeks of August, significantly more than usual. Since June, flooding has displaced as many as 124,600 people across 13 of Sudan’s 18 states, according to the United Nations (UN). The flooding has severely curtailed efforts to deliver food. People in some parts of Sudan are experiencing famine conditions, and millions of people face acute food insecurity, according to the Famine Early Warning Systems Network (FEWS NET). FEWS NET, established by the United States Agency for International Development (USAID), provides timely, evidence-based early warning information and analysis of current and future acute food insecurity. NASA is among the organizations that partner with USAID to produce FEWS NET warning information and analysis. Wildland Fires Scorch Idaho Wilderness References & Resources FEWS NET (2024) Sudan.

Excited to share my most recent article, published in the special issue Grounded Sociohydrology from #JournalofHydrology 😊 Traditional hydrological models for urban flood risk management offer valuable support but overlook the complex interplay between hydrological and non-hydrological factors, hampering effective strategies❗ This work proposes a participatory 👥 #sociohydrological modelling approach based on #SystemDynamics (SD) to #quantitatively analyse the interactions and feedback between flood risk and different aspects of the urban system. Furthermore, the role of #BlueGreenInfrastructure 🌳 in enhancing urban flood resilience is explored. Such an approach can complement traditional hydrological models and offer decision-makers actionable insights into flood risk and resilience. ✨ Although reference is made to one of the case studies of the #CUSSH (Complex Uran Systems for Sustainability and Health)and #CAMELLIA (Community Water Management for a Liveable London) projects, the modelling approach can be implemented in different contexts. https://lnkd.in/dFjx6u_G #UrbanFlooding #ComplexSystems #SocioHydrology #StakeholderEngagement #BlueGreenInfrastructure #SystemDynamics #QuantitativeModelling

Pooling international flood data could be the key to anticipating megafloods in Europe. Research suggests that sharing data from different regions, rather than relying solely on local data, could have predicted 95% of the surprising, extreme floods in Europe between 1999 and 2021. While challenges like language barriers and differing standards exist, the study highlights the potential to enhance disaster anticipation by looking beyond local data. The findings could be crucial for civil protection scenarios, providing insights into the worst possible flood events and emphasizing the importance of international cooperation in data sharing. #FloodData #DisasterPrevention #Megafloods #ClimateResilience #DataPooling #RiskAssessment #GlobalCollaboration #ClimateScience #NaturalDisasters #EnvironmentalResearch

“The whole purpose of this paper is to provide data to support decisions. Every city, every county has a flood resiliency plan in place. They are required by law to create that. But it’s likely nobody has received the entire picture until this study, which creates probably the first comprehensive picture of what’s happen in the not-too-distant future.”- Manoochehr Shirzaei, Director of Virginia Tech’s Earth Observation and Innovation Lab on the short term picture of coastal flooding risks. In this article, learn about the work of Shirzaei and his research team who have built some of the world's first high-resolution depictions of the sinking land along U.S. coastline. The recent study provides a new comprehensive look at the flood risks for 32 cities on three coasts by 2050.▶ https://lnkd.in/eVhekMRQ More information on the Earth Observation and Innovation Lab here : https://lnkd.in/e9R-qjB5 #coastalresilience #coastalprotection #flooding #virginiatech
