WADDEN REGION—57 7 Financing—59 3 Introduction For a low-lying delta such as the Netherlands, it is essential to continue working on flood risk management and sustainable freshwater supplies. We have more people and greater economic value to protect than we did sixty years ago. The climate is also changing, with sea levels rising and the ground subsiding. Rainfall is more frequent and heavier and there is a greater likelihood of very dry periods and salinisation. The Cabinet believes it is important to keep the Netherlands safe, liveable and economically attractive. To help ensure this, the central government, provinces, water boards, municipalities and social organisations have spent the last few years working on the flood risk management and freshwater supply challenges in the Delta Programme. The result: a proposal for Delta Decisions and area-based strategies in the Delta Programme 20151. The reason underlying the Delta Programme is the recommendation from the Delta Committee headed by Prof. C. Veerman (2008). The Cabinet finds that, using major interventions to climate-proof the Netherlands for the future, the ‘Veerman recommendation’ has been cut back to pragmatic solutions. The current water system in the Netherlands by and large still suffices for the time being (until 2050). However, we do stand to gain from making the current system more flexible and robust, which will make it more resistant to extremes. In addition, the Cabinet also opts for a fundamentally different flood risk management policy, doing away with the current system of standards, which dates back to the 1960s. Moreover, the Cabinet will change its freshwater policy, as there will be a growing shortage of freshwater supplies in the future and it is advisable for the government to indicate how much freshwater is available so that users can revise their investments accordingly. The Cabinet is also seeking to organise the Netherlands in a more water-robust and climate-proof fashion; this will contribute to a healthy living environment and is key to an attractive investment climate. Water and other spatial interests have a significant impact on each other. First of all, there may be smart combinations in which spatial organisation can play an important role in solving the water challenges. Secondly, the water challenges for flood risk management and freshwater supplies must consider spatial interests from early on, both when establishing and when implementing the challenges. This applies in any event to urban areas and developed river dykes, such as in Rhine Estuary- Drechtsteden. There are also areas where there are opportunities to link in with nature ambitions, such as along the sandy coast and in the IJsselmeer region. There are opportunities in the area around the major rivers for a comprehensive approach to promising locations for river widening. The Cabinet will continue its adaptive approach to the Delta Programme. By knowing what is needed in the long run and considering the various delta scenarios, we can do what is necessary in the short term while leaving the options for the longer term open. The Cabinet favours flexible solutions that can be adapted to new insights in the longer term, preferring solutions that accommodate natural processes and building with nature wherever possible. The Cabinet also encourages innovation aimed at, for example, maintaining and capitalising on our international standing as water experts. 1 House of Representatives, session year 2014-2015 4 This interim revision embeds national policy and the required actions on a national level that follow from the proposal for Delta Decisions and preferential strategies in the Delta Programme 2015 into the National Water Plan (NWP). As such, the plan provides the basis for elaborating and implementing this national policy. An environmental impact statement (plan-EIS) has been drafted for this revision, which includes an appropriate assessment. This statement indicates that the draft plan comprises a large number of process-related policy choices, which must be specified in more detail to gain insight into the environmental effects. The statement also finds that the environmental impact of the more framework-setting policy choices is mostly moderate and generally positive. The appropriate assessment shows that the policy choices can be implemented within the preconditions of the Nature Conservation Act. The ambition is to fully integrate the revision of the NWP into the second NWP (December 2015). The Draft Plan for the Interim Revision and the plan-EIS were available for inspection from 17 September 2014 to 28 October 2014. 44 points of view were submitted. The points of view submitted were addressed in a Report of Answers, stating whether the points of view were grounds for any amendments to the plan. The plan was updated and edited in a number of respects; these amendments have also been included in the Report of Answers. The Committee for the Environmental Impact Statement has issued advice on the plan- EIS. The Committee’s advice states that the EIS contains essential information to be able to take a decision on the interim revision, with the environmental interests being fully taken into account. The Committee recommends that the Synthesis Document on the Safety sub-programme should be regarded as a part of the EIS. As the EIS contains all essential information, this recommendation is not adopted. The Synthesis Report on the Safety subprogramme is regarded as a key building block for substantiating the choices in the Delta Programme with regard to the new standards and it is available as an appendix to the Delta Programme 2015. The other points of the Committee’s advice have been taken into account or will be considered in the follow-up process. The interim revision was drawn up by the Minister for Infrastructure and the Environment and the State Secretary for Economic Affairs. Details regarding flood risk management policy have been coordinated with the Ministry of Security and Justice. The interim revision dovetails with other national policy documents, such as the Framework Vision on Infrastructure and Space2, the Vision on Cultural Heritage and Space3 and the Climate Agenda4. The NWP is binding upon the central government; the Cabinet asks other government authorities to convert elements of the Delta Programme 2015 that are relevant for them into their own policy plans, as was agreed in the Administrative Agreement on the Delta Programme. National Water Plan 2009-20155 The Water Act lays down that the central government will revise the National Water Plan (NWP) once every six years. The first water plan, the NWP 2009-2015 contains the broad outlines for national water policy and the related aspects of spatial policy. Based on the Spatial Planning Act (abbreviated as Wro in Dutch), the NWP is also a ‘framework vision’ where spatial aspects are concerned. As such, the instruments 2 House of Representatives, session year 2011-2012, 32 660, no. 51 3 House of Representatives, session year 2010-2011, 32 156, no. 29 4 House of Representatives, session year 2013-2014, 32 813, no. 70 5 House of Representatives, session year 2009-2010, 31 710, no. 12 5 available under the Spatial Planning Act can also be used for policy implementation. This plan outlines the spatial aspects in separate sub-sections in each section. Progress of the policy objectives and actions from NWP 2009-2015 is reported to the House of Representatives every year in ‘Water Mapped Out’. In the NWP 2009-2015, which was published on 22 December 2009, the Cabinet announced that it would introduce new standards based on flood probability and aim for ‘multi-layer safety’. The Cabinet also announced a decree on freshwater supplies and that it intends to make water policy more spatial and spatial policy ‘wetter’. The adaptive approach already announced in the NWP has been elaborated and applied in more detail in the Delta Programme. The same applies to encouraging designers’ efforts in looking for comprehensive solutions for the water challenges. 6 Map 1: Flood risk management and freshwater challenges 7 Key to map 1 Opgaven Challenges Waterveiligheid Flood risk management waterkering op orde brengen, grote repair flood defence system, major tasking opgave repair flood defence system waterkering op orde brengen flood defence system management onderhoud waterkering preserve sandy coastal system in stand houden zandig kustsysteem storm surge barrier maintenance tasking onderhoudsopgave stormvloedkering maintain water discharge

Lambertz - Chair of the Monitoring Committee for the Euregio Meuse-Rhine Interreg Programme - Director of Euregio Meuse-Rhine - Minister-President of the German-speaking community of Belgium 1. General background and geographical situation In 1974, the governors of the Dutch and Belgian provinces of Limburg, together with the Chief Executive of the Cologne county administration, acted on the proposal made to them by the future Queen of the Netherlands, Princess Beatrix, during an official visit to Maastricht, to draw up draft arrangements for an association under which even closer cross-border collaboration could develop, along the lines of the Dutch-German Euregio project that had been running since 1957. This initiative was part of the new Community direction in regional policy, which in 1975 was to be provided with an instrument to assist economic development called the European Regional Development Fund (ERDF). In 1976, the principle of cross-border institutions was passed in law. Initially formed as an ad hoc association, the Euregio Meuse-Rhine was designed to promote integration between inhabitants on each side of the national borders. The area covers: • in Holland: the southern part of the Dutch province of Limburg; • in Germany: the city of Aachen, and the districts of Aachen, Heinsberg, Düren and Euskirchen, which make up the Aachen Regio, and • in Belgium: the entire province of Limburg. The province of Liège joined the Euregio Meuse-Rhine in 1978. In 1992, the German-speaking community of Belgium became the fifth partner in the Euregio Meuse- Rhine.

We zullen moeten leren omgaan met grotere hoeveelheden water (zeespiegelstijging, grotere rivierafvoeren, extremere hoeveelheden neerslag), maar ook met grotere perioden van droogte. De zomer van 2018 staat wat dat betref nog vers in het geheugen. Beschikbaar zoet water is schaars op wereldschaal. Het meeste water op aarde is zout, en veel van het zoete water zit in gletsjers, of in de ondergrond. Slechts een klein deel is beschikbaar in meren en rivieren. Het IJsselmeer – inclusief Markermeer en Randmeren – is een grote regenton met kost- baar zoet water van prima kwaliteit voor een groot deel van Nederland. Het watersysteem functioneert nog goed, maar loopt wel op tegen de grenzen vanwege klimaatverandering. Door innovatie wegen naar de toekomst verkennen Het is verstandig om ons op die verandering voor te bereiden. Rijkswaterstaat verkent daarom samen met partners nu al mogelijke oplossingsrichtingen die ons in de toekomst kunnen helpen. Dat doen we door te innoveren en te zoeken naar vernieuwende manieren om met het water om te gaan.

    THE DUTCH DELTA MODEL FOR POLICY ANALYSIS ON FLOOD RISK MANAGEMENT IN THE NETHERLANDS R.M. Slomp1, J.P. de Waal2, E.F.W. Ruijgh2, T. Kroon1, E. Snippen2, J.S.L.J. van Alphen3 1. Ministry of Infrastructure and Environment / Rijkswaterstaat 2. Deltares 3. Staff Delta Programme Commissioner ABSTRACT The Netherlands is located in a delta where the rivers Rhine, Meuse, Scheldt and Eems drain into the North Sea. Over the centuries floods have been caused by high river discharges, storms, and ice dams. In view of the changing climate the probability of flooding is expected to increase. Moreover, as the socio- economic developments in the Netherlands lead to further growth of private and public property, the possible damage as a result of flooding is likely to increase even more. The increasing flood risk has led the government to act, even though the Netherlands has not had a major flood since 1953. An integrated policy analysis study has been launched by the government called the Dutch Delta Programme. The Delta model is the integrated and consistent set of models to support long-term analyses of the various decisions in the Delta Programme. The programme covers the Netherlands, and includes flood risk analysis and water supply studies. This means the Delta model includes models for flood risk management as well as fresh water supply. In this paper we will discuss the models for flood risk management. The issues tackled were: consistent climate change scenarios for all water systems, consistent measures over the water systems, choice of the same proxies to evaluate flood probabilities and the reduction of computation and analysis time.

  • 41. the Meuse–Rhine Euroregion: a Laboratory for Police and Judicial Cooperation in the European Union*
    41. THE MEUSE–RHINE EUROREGION: A LABORATORY FOR POLICE AND JUDICIAL COOPERATION IN THE EUROPEAN UNION* 1. Introduction Over the past few decades, economic and social integration within the European Union (EU) has rapidly gained momentum. This integration has been largely facili- tated by the Schengen Implementation Convention of 1990, which abolished border controls between the member states.1 However, this easing of border controls has also improved and expanded the opportunities for criminals to engage in cross-border illegal activities. Therefore, police and judicial cooperation has now become a high priority on the European Union’s agenda. The authorities in urbanized border areas are usually the first to be confronted by new developments in cross-border crime. As a result, opportunities for law- enforcement cooperation are quickly grasped, and practical innovations are devised as far as the conventions permit. Hence, border areas often serve as ‘laboratories’ for police and judicial cooperation. A clear example of this is the Meuse-Rhine Euroregion, located in the border areas of the Netherlands, Belgium and Germany. From a scholarly point of view, jurists have largely dominated the discussion about police and judicial cooperation (Corstens and Pradel 2002; Peers 2000; Sabatier 2001). This is easily explained by the fact that up until now criminologists have con- ducted relatively little empirical research on this topic. However, the Meuse-Rhine Euroregion is an exception to the rule, as several studies about police and judicial cooperation with regard to the area have been published over the years (Hofstede and Faure 1993; Spapens 2002, 2008a; Spapens and Fijnaut 2005).

    Silt in the Markermeer/IJmeer A study on the effectivity and efficiency of proposed approaches concerning the deterioration of the lake and its surroundings Student: Iris van Gogh (3220052) Environmental biology Ecology and Natural Resources Management Supervisor: Dr. J.N.M. Dekker Energy and Resources Copernicus Institute of Sustainable Development Faculty of Geosciences, Utrecht University December, 2012 Preface Since I was born in Lelystad, the capital of the county Flevoland in the Middle of the Netherlands, I lived near the Markermeer for about 18 years of my life. I still remember the time being on an airplane and my dad showing me the Markermeer and IJsselmeer below us. The difference in color (blue for the IJsselmeer, while green/brown for the Markermeer) was enormous, and I know now, this is mainly caused by the high amount of silt in the Markermeer. A couple of years later I was, again due to my father, at an information day about water, distributing ‘dropjes’, a typical Dutch candy, wearing a suit looking like a water drop, named ‘Droppie Water’. I think it were those two moments that raised my interest for water and even though I was not aware of it at that time, I never got rid of it. Thanks to the Master track ‘Ecology and Natural Resources Management’ which I started in 2011, my interest for water was raised once, or actually thrice, again. After my first internship, which was about seed dispersal via lowland streams and arranging my second internship about heavily modified water bodies in Sweden (which I planned for the period between half of December 2012 and the end of July 2013) I wanted to specialize this master track in the direction of water.

    TOPICS IN MARINE BIOLOGY. ROS. J. D. (ED.). SCIENT. MAR . 53(2-3): 457-463 1989 The ecology of the estuaries of Rhine, Meuse and Scheldt in the Netherlands* CARLO HEIP Delta Institute for Hydrobiological Research. Yerseke. The Netherlands SUMMARY: Three rivers, the Rhine, the Meuse and the Scheldt enter the North Sea close to each other in the Netherlands, where they form the so-called delta region. This area has been under constant human influence since the Middle Ages, but especially after a catastrophic flood in 1953, when very important coastal engineering projects changed the estuarine character of the area drastically. Freshwater, brackish water and marine lakes were formed and in one of the sea arms, the Eastern Scheldt, a storm surge barrier was constructed. Only the Western Scheldt remained a true estuary. The consecutive changes in this area have been extensively monitored and an important research effort was devoted to evaluate their ecological consequences. A summary and synthesis of some of these results are presented. In particular, the stagnant marine lake Grevelingen and the consequences of the storm surge barrier in the Eastern Scheldt have received much attention. In lake Grevelingen the principal aim of the study was to develop a nitrogen model. After the lake was formed the residence time of the water increased from a few days to several years. Primary production increased and the sediments were redistributed but the primary consumers suchs as the blue mussel and cockles survived. A remarkable increase ofZostera marina beds and the snail Nassarius reticulatus was observed. The storm surge barrier in the Eastern Scheldt was just finished in 1987.

During the operation, the Germans allegedly recovered a copy of the Market- Garden plan from the body of a British officer, who should not have carried it into combat. With this gun he engaged an enemy self propelled gun which was appoaching to attack. Luckily for the British tankers, most of the 88mm guns were sited for antiaircraft work and could not bear on the tanks as they used rubble around some factory buildings and a power station for cover. The unit set off to the bridge late and having traveled only a short distance the vanguard was halted by a strong German defensive position; the squadron could make no further progress.

While agreeing that Montgomery's drive towards the Ruhr should have priority, he still thought it was important to "get Patton moving again". Approximately 3, survivors of the 1st Airborne Division established themselves in the buildings and woods around Oosterbeek with the intention of holding a bridgehead on the north side of the Rhine until XXX Corps could arrive. Only his tank and one other made it this far; the other two were knocked out on the bridge, though one later rejoined the troop.
