Let’s take action now before it’s too late!

National and regional governments, local authorities and communities, water corporations, and scientists must collaborate urgently to enhance flood prevention, warning, coordination, and emergency management tools at the local level in disaster risk reduction programs. The necessity for immediate action became obvious following the flooding events that occurred around the world in 2021. Many people worldwide … Read more

Floods and slides in Indonesia and Timor: displaced peopel as a result of natural disasters

Indonesia has suffered 1.030 natural disasters so far in 2021, including earthquakes, floods, landslides, fires and tornadoes, which, not counting the victims of the lates floods, caused 282 deaths. Landslides and flash floods are frequent in the Indonesian archipelago, especially in the rainy season.  Environmental defenders claim that deforestation favors these catastrophes. The National Disaster … Read more

Reflecting on French Flood Policy in the Pays de la Loire Region

In the French Pays de la Loire region, where AA-Floods partner Université de Nantes is located, heavy rains in early- to mid-February caused flooding or evacuations due to flood risk in the towns of Ancenis, Rochefort-sur-Loire, several towns in the Vendée department, and towns in the wetlands southwest of Nantes, among others. Warnings issued on … Read more

The MaxEnt Methodology in Generating Multiple Hazard Maps for Floods

The article Evaluation of multi-hazard map produced using MaxEnt machine learning technique, published las March in the journal Nature, proposes the elaboration of maps of multiple hazards from the use of the MaxEnt* methodology (Maximum Entropy) for the identification of areas sensitive to large-scale hazards. As explained in the Nature article: “Maximum entropy has been … Read more

VIRTUAL REALITY, an effective pedagogical tool to inform and sensitize citizens about floods

The new technological resources that we have available on our mobile devices, especially virtual reality and augmented reality, allow us to disseminate relevant and useful information to a greater number of recipients, and to raise awareness on topics of general and particular interest. Accessibility to that information is key: The channel used and how it … Read more

Nature science journal: evidence of the impact of Climate Change on Floods

In the article published in Nature International Journal of Science on August 28, 2019 (follow the link at the bottom of this news) a team of scientists led by Günter Blöschl and Julia Hall (Institute of Hydraulic Engineering and Water Resources Management, Technische Universität Wien), and by Nenad Zivkovic (Faculty of Geography, University of Belgrade) explains in a direct, accessible and enjoyable way how the attribution of European floods to Climate Change is hindered by the lack of a consistent signal in the field studies due to limited spatial coverage and number of hydrometric stations.

However, with regional/local scale analysis, such as AA-FLOODS advocates, this article demonstrates the existence of clear regional patterns of increases and decreases in river flood discharges observed in the last five decades in Europe, which are manifestations of a changing climate.

Water retention in the atmosphere by Global Warming

The study links the increase in river flooding as a result of the greater water retention capacity of a warmer atmosphere. These concerns are reinforced by evidence of the increase in economic losses associated with floods in many parts of the world, including Europe.
Any change in river floods would have lasting implications for the design of flood protection measures and the zoning of flood risk.

Regional variations and need for Management in detail scales
The results of this research arise from the most complete database of European floods so far, and suggest that:
1) the increase in fall and winter rainfall has resulted in increasing flooding in northwestern Europe
2) the decrease in rainfall and the increase in evaporation have led to a decrease in flooding in the medium and large basins in southern Europe
3) The decrease in snow cover and thaw, as a result of warmer temperatures, has caused a decrease in flooding in Eastern Europe.

Regional trends in flood discharge in Europe vary from an increase of approximately 11% per decade to a decrease of 23%. Despite the spatial and temporal heterogeneity of the observation record, the changes in floods identified by the article are broadly consistent with the projections of the climate model for the next century, suggesting that climate-driven changes already calls for attention to politicians and technicians to consider climate change as an essential factor in flood risk management are taking place.
