Delta Programme Programme 2021 Dear Mr and Madam Chairperson, CommissionerIt is my pleasure to present to you the Delta Programme 2021 (DP 2021). The Delta Programme is the annual proposal developed by the Delta Programme Commissioner concerning the fields of flood risk management and freshwater supply, which – as stipulated in Article 4.10 Paragraph 1 of the Water Act – is presented to you once a year. DP2021 has been developed in close collaboration between the national government, the municipalities, the district water boards, the provinces, NGOs, and the business community; it is widely supported by all the parties concerned. In the light of the current situation with the COVID-19 virus, this is a particularly great achievement, for which I would like to express my appreciation to the Delta Programme Commissioner and all the other parties involved. With DP2021, the Delta Programme is entering a new phase. DP2021 features the outcomes of the first six-year review of the Delta Decisions and regional Preferential Strategies that were set down in 2015. Knowledge on climate change is growing, and the effects of measures are increasingly manifest. Yet at the same time, reality is continuously changing, and new insights develop. With this review, the course pursued by DP2021 has been adjusted where necessary, in order to enable us to keep flood risk management, freshwater availability, and spatial planning in the Netherlands sustainable and resilient in the long run, and to continue to accommodate the (increasing) climate extremes. In his cover letter to Delta Programme 2021, the Delta Programme Commissioner has included the following three appeals and recommendations, based on the review of the Delta Decisions, strategies, and measures: 1. An appeal to the managing authorities of flood defence systems and to other parties involved to ensure that flood protection will be up to par by 2050. In addition, a request to take full account of cyber resilience in their efforts; 2. An appeal to both the national and the regional parties (including the private sector) to intensify their pursuit of the climate resilience of vital and vulnerable functions; Pagina 1 van 4 6 | Delta Programme 2021 3. An appeal to politicians to ensure that COVID-19 will not stagnate the work on Ministry of Infrastructure the Delta Programme taskings, which are of existential importance for the and Water Management Netherlands. In line with this appeal, he strongly advises against the option of delaying the implementation of the Flood Protection Programme, as proposed Our reference IENW/BSK-2020/91211 by the administrative Broad Social Review working group (Ready for Climate Change), in view of the changing climatological conditions. Furthermore, the Delta Programme Commissioner urges that the proposals regarding the intensification of climate adaptation and enhancing the resilience of the freshwater supply should be adopted, to a significant extent, in the coalition agreement of the next Cabinet. In this respect, he points out that especially in times like these, (anticyclic) investments in the existential safety, liveability, and climate adaptation of our country can bolster economic recovery and sustainable economic growth in the years ahead. Cabinet response Below, as stipulated by Article 4.9, paragraph 7 of the Water Act, I will indicate how the Cabinet intends to accommodate the Delta Programme Commissioner’s recommendations. 1. Flood risk management to be up to par by 2050 One of the goals of flood risk management policy is that by no later than 2050, every resident of the Netherlands living behind primary flood defences must be assured of a minimum protection level of 10-5, i.e., the probability of fatality due to flooding does not exceed 1:100,000 per annum. To ensure that all the primary flood defences meet this standard by 2050, current insights dictate the completion of an average of approx. 50 kilometres of dyke improvements per annum, between now and 2050. For the period 2021-2032, the Flood Protection Programme has scheduled the improvement of 698 kilometres of dykes and 171 engineering structures.
