It comes shortly after intense rainfall and flooding wreaked devastation throughout components of western Europe earlier this month.
Germany and Belgium were the worst-hit countries by the acute rainfall on July 14 and July 15, with authorities reporting greater than 200 individuals to have died as floods engulfed complete villages. Elements of Switzerland, France, Luxembourg and the Netherlands had been additionally badly affected.
But, whereas the Meuse River — which flows via France, Belgium and the Netherlands — reached record high water levels, the size of destruction within the Netherlands was not the identical as seen elsewhere.
Flood specialists advised CNBC that whereas there are a number of causes that make it tough to instantly evaluate the destruction seen within the Netherlands with different nations in western Europe, many years of funding into flood preparedness definitely helped to restrict the harm.

“It was a horrible catastrophe. Individuals misplaced their lives and other people misplaced associates and households, so there may be nothing to brag about. The Netherlands didn’t see the huge rain Germany noticed or Belgium noticed,” Henk Ovink, a flood professional and the Netherlands’ particular envoy for worldwide water affairs, advised CNBC by way of phone.
One key cause the Netherlands was in a position to deal with a considerable amount of water transferring via its river system through the current flooding catastrophe was that “a variety of effort” and funding had gone into enhancing the nation’s flood protection lately, Ovink stated.
These measures included the widening and deepening of river channels as a part of the federal government’s so-called “Room for the River” coverage, a excessive degree of safety for dams, dikes and levees and evacuation schemes to ensure that individuals might be moved to secure locations.
“I do not need to evaluate [to other countries], but when I have a look at the Netherlands, our efforts helped and labored. On the identical time, as at all times with these challenges that our society faces, we’ve got to make use of this catastrophe once more as a stepping stone or a studying second,” Ovink stated.
“A catastrophe is like an X-ray. It exhibits the system’s vulnerability and exhibits all these interdependencies within the water and concrete and infrastructure and societal programs. If you happen to actually take a more in-depth look then you possibly can discover ways to put together higher for future challenges. I believe that’s now the burden but in addition the chance,” he added.
Reflecting on the floods seen in Europe in current weeks, Ovink proposed 3 ways for nations to enhance flood preparedness: “First, take local weather change into consideration in every thing you do,” he stated, referring to a key intention of the Paris Settlement to restrict an increase within the Earth’s temperature to 1.5 levels Celsius above pre-industrial ranges.
“Second, with each funding you place in place, take into consideration nature’s capability to assist construct resiliency and adaptive capacity. And third, do that with all stakeholders, from the group degree up.”
The Netherlands has a protracted historical past of water administration, although researchers cite the devastating North Sea flood of 1953 as a pivotal second for the nation. The flood induced widespread harm and killed 1,835 individuals nationwide. It prompted the development of the Delta Works, the world’s largest flood safety system, within the southwestern a part of the nation.
Many years later, floods within the Rhine and Meuse rivers in 1993 and 1995 saw more than 200,000 people evacuated from their houses as a precautionary measure. The near-catastrophic occasions triggered a change in perspective to water protection and shortly paved the best way for the “Room for the River” program.
William Veerbeek, an city flood administration professional on the IHE Delft Institute for Water Schooling, singled out the “Room for the River” coverage as notably necessary, saying the nation’s strategy to flood danger had “actually paid off” in current weeks.
“The Room for the River program focuses totally on huge rivers, and since we’re the delta the place all of the water finally discharges into the ocean, that’s particularly necessary for us,” he advised CNBC by way of phone.
“For different nations, too, creating more room for the water is crucial as a result of the larger the river, finally the larger the disaster if that river floods. On the smaller streams although, the place we noticed the devastation, there’s additionally actually a problem of preparedness. And within the Netherlands, we will additionally make investments extra in that and get higher at that.”
Flood specialists advised CNBC that large-scale early warning programs, emergency evacuation methods and plans to make sure that individuals know what to do when the time comes had been all important instruments to policymakers in search of to enhance flood preparedness.
“There’s additionally a spatial planning element,” Veerbeek stated, noting that among the German villages that incurred essentially the most devastation had been historic areas which were populated for hundreds of years.
“However you can have a legit query now,” he stated. “A whole lot of the buildings have actually been completely broken and want critical reconstruction or to be fully rebuilt. And you’ll ask your self, ought to we construct again on the identical place and on the identical places?”

On the very least, Veerbeek stated it will be necessary to reassess the places of susceptible infrastructure websites similar to emergency providers, retirement houses and hospitals to ensure that they don’t seem to be positioned in notably susceptible floodplain areas.
What’s extra, a brand new technology of city planners and designers with an elevated consciousness of climate-related dangers may very well be anticipated to make a giant distinction in the case of the planning of recent residential districts.
“I’d say these are two fields by which all three nations on this case can nonetheless enhance on,” Veerbeek stated.
Local weather scientists expect excessive climate occasions to grow to be more and more frequent amid the local weather emergency. The warning comes as floods have wreaked havoc in Europe and China, poisonous smoke plumes have blanketed Siberia and unprecedented warmth in western North America have triggered devastating wildfires in current weeks.
“I believe what is very fascinating in regards to the current floods is that often on the Meuse River, and many of the areas the place it flooded, you’d count on floods to happen in winter — when there may be a variety of rainfall that goes on for a number of days, the entire basin is saturated after which it floods,” Philip Ward, professor of world water danger dynamics at Vrije Universiteit in Amsterdam, advised CNBC by way of phone.
“Whereas in the summertime, often the river ranges are literally fairly low as a result of there may be a variety of evapotranspiration. However this time the floods got here in summer season when you wouldn’t usually count on this to be the case. With local weather change, it’s precisely these kinds of occasions that we count on to grow to be extra widespread.”
