Institutional Map FRM NL
NL Advisory Taskforce Flooding
 Aim Advisory Task Force on Flooding: draw lessons +
accelerate measures to protect all Dutch regions
 Advisory Task Force is made up by representatives of
the central government, umbrella organisations of
subnational authorities (like provinces, waterboards,
local councils), regional authorities Limburg and the
Delta Programme Commissioner.
 Two advisory reports: the first was in March 2022, the
second (and final) in Dec. 2022.
 Implementing the 25 recommendations of
this initial advisory report will increase the
resilience to future extreme rainfall events.
 Enhance existing and new international cooperation,
particularly in regional water systems
Cross border stresstest
 examine with neighboring countries
whether cross-border stress tests for
regional water systems can be carried out
in border regions
 Initial development of methods/manuals
for cross-border stress tests together with
neighboring countries/border regions
Expanding the shared knowledge base
 Establishment of a cross-border project
team per border region and strengthening
of dialog with Lower Saxony and North
Rhine-Westphalia, Wallonia, Flanders and
other regions
 Comparison of cross-border regional
spatial visions/approaches/work programs
and search for commonalities that form a
basis for cooperation
 Establishment of an international pool of
experts to develop a needs-based
knowledge agenda for regional waters
and to conduct independent research
(JCAR-ATRACE)

• Roadmap to Improve Transnational Collaboration – EU water
Summit 26 March 2024
• “It is our responsibility as governments to take action…
• “This roadmap is more than just a document, it is a joint commitment
towards the people of the BeNeLux (+) and the beginning to intensify
transnational flood and drought risk management…
• “A working group must now translate the principles of the roadmap into a
BeNeLux (+) Water agenda and concrete actions…
› Joint declaration – Government Consultations Netherlands - Germany 27 March 2023:
Furthermore, our countries will continue and intensify their cooperation on climate
adaptation and mitigation efforts. In addition, we will continue and intensify our
cooperation on water management and our knowledge exchange regarding the risks of
droughts, floods and pollution.
› Benelux Prime Ministers’ Summit Joint Declaration 29 November 2023: The floods in
2021 (and in recent weeks) in the larger Benelux region, remind us that our countries are
not spared by the impact of climate change. The Benelux Water Day on enhanced
cooperation in regional flood risk and drought management, which takes place today in
Maastricht, is a first step to work towards a joint Benelux agenda and a coordinated
effort in 2024 to improve our preparedness for extreme weather events.”
