  • Interreg I / Ii : Cross-Border Cooperation
    INTERREG I / II : CROSS-BORDER COOPERATION Euregio Meuse-Rhine: implementation and management in practice Speech by Mr K.H. 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.

  • 1 the DUTCH DELTA MODEL for POLICY ANALYSIS on FLOOD RISK MANAGEMENT in the NETHERLANDS R.M. Slomp1, J.P. De Waal2, E.F.W. Ruijg
    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).

  • The Ecology O F the Estuaries of Rhine, Meuse and Scheldt in The
    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.

  • Half a Century of Morphological Change in the Haringvliet and Grevelingen Ebb-Tidal Deltas (SW Netherlands) - Impacts of Large-Scale Engineering 1964-2015
    Half a century of morphological change in the Haringvliet and Grevelingen ebb-tidal deltas (SW Netherlands) - Impacts of large-scale engineering 1964-2015 Ad J.F. van der Spek1,2; Edwin P.L. Elias3 1Deltares, P.O. Box 177, 2600 MH Delft, The Netherlands; [email protected] 2Faculty of Geosciences, Utrecht University, P.O. Box 80115, 3508 TC Utrecht 3Deltares USA, 8070 Georgia Ave, Silver Spring, MD 20910, U.S.A.; [email protected] Abstract The estuaries in the SW Netherlands, a series of distributaries of the rivers Rhine, Meuse and Scheldt known as the Dutch Delta, have been engineered to a large extent. The complete or partial damming of these estuaries in the nineteensixties had an enormous impact on their ebb-tidal deltas. The strong reduction of the cross-shore tidal flow triggered a series of morphological changes that includes erosion of the ebb delta front, the building of a coast-parallel, linear intertidal sand bar at the seaward edge of the delta platform and infilling of the tidal channels. The continuous extension of the port of Rotterdam in the northern part of the Haringvliet ebb-tidal delta increasingly sheltered the latter from the impact of waves from the northwest and north. This led to breaching and erosion of the shore-parallel bar. Moreover, large-scale sedimentation diminished the average depth in this area. The Grevelingen ebb-tidal delta has a more exposed position and has not reached this stage of bar breaching yet. The observed development of the ebb-tidal deltas caused by restriction or even blocking of the tidal flow in the associated estuary or tidal inlet is summarized in a conceptual model.

A review of the past and present status of anadromous fish species in the Netherlands: is restocking the Rhine feasible? S.J. de Groot1 Netherlands Institute for Fisheries Research (RIVO-DLO), P.O. Box 68, 1970 AB IJmuiden, The Netherlands 1 Present address: Brederoodseweg 49, 2082 BS Santpoort-Zuid, The Netherlands Key words: anadromous fish, Rhine, decline, extinction, restocking, feasibility Abstract The paper reviews the past, present and future of eight anadromous fish species inhabiting the Lower Rhine (The Netherlands), viz. -sturgeon (Acipenser sturio), whitefish and houting (Coregonus lavaretus, C. oxyrinchus), smelt (Osmerus eperlanus), allis and twaite shad {Alosa alosa, fallax),A. sea trout {Salmo trutta) and salmon {Salmo salar). All species are under threat or became extinct (e.g. sturgeon, allis shad). It is not possible to single out a specific factor for the decline or disappearance. A combination of factors is responsible, as the degradation of the spawning and nursery areas, river correction for shipping, building of sluices and hydropower dams, extraction of sand and gravel and river pollution. The likelihood that a species will return via natural recovery, or restocking is assessed. The return of the sturgeon is unlikely. Present observations of sturgeon can be attributed to releases of unwanted sturgeon hybrids. A natural stock of coregonids in Dutch waters seems not feasible any more due to irreversible habitat degradation. Present day catches originate from German releases.

  • Case Study of Flood Control in the Netherlands Natural Disasters Have
    Case Study of Flood Control in the Netherlands Natural disasters have become much more violent, causing excessive damage to humankind. Among the most common and frequent natural disasters are inundations or floods. Many countries lack the capacity to deal with the destructive power of overflowing water, but the Netherlands has managed to exert control over its flooding situations. In fact, this small country is known for having the world’s best flood control system, in which advanced technologies and innovations have been integrated into the fight against inundations. The name Netherlands—meaning low countries—is befitting, since most of its landmass is below sea level. More than 60% of the country’s surface area are at risk of being inundated, including its international airport, which is 5 meters below mean sea level. The region that is now the Netherlands has dealt with floods for more than 2,000 years, but the Dutch have never given up. Their saying “God created the world but the Dutch created the Netherlands” is exemplary of their ability to cope with natural disasters. Flooded Area in the Absence of All Water Defences Safety Standard per Dike-Ring Area Water Defenses Images depicting the Netherland’s flood-risk area and flood control solutions During the historic North Sea Flood of 1953, the storm and sea waves of 16 feet obliterated the shorelines of Scotland, Belgium, England, and the Netherlands. Among over 2,000 casualties were 1,835 Dutch citizens, and more than 70,000 people were displaced. About 150,000 hectares of the surface area or 9% of the entire country was under water.
