For about 20 years models have been used on a large scale in the water management of The Netherlands. Today models are indispensable in modern water management. However, while on one hand the application of models in water management still increases, on the other hand the appreciation of policy makers for models decreases, especially in the Dutch national policy. One has to look very carefully to recognise the policy analysis by models in the policy documents, although the number of used models and the number of calculations was larger than ever before. Summarised it may be stated that the application of models is facing some serious problems. Especially the efficiency must increase. Together with the coming, new questions in water management, the involved participants in integrated water management are forced to join forces in the development and application of models. Therefore in The Netherlands a Standard Framework discussion started between the involved participators. The first results are very promising. Looking at the future it can be concluded that the next generation of models to be built for the fifth National Policy Document on Water Management, will not just be a model system of the national government, but a system of all involved participants in Dutch water management.

Road traffic is a diffuse source of heavy metals and oil that leads to pollution of verges and surface water in areas immediately surrounding roads. The Commission for Integrated Water Management (CIW) has drawn up a policy document addressing methods for managing this type of pollution. The document is based on results from numerous studies in The Netherlands targeting pollution caused by traffic. The Commission concludes that measures at the source are the only way to realise sustainable solutions. For example, attention should be devoted to the issue of zinc emissions from car tyres and crash barriers. The concept of controlled infiltration is recommended for combating pollution caused by spray and runoff from roads. This includes periodic chemical inspection of verge pollution and, where necessary, replacement of the verge's top layer. The application of porous asphalt on highways in The Netherlands has also proven highly effective in limiting pollution caused by traffic, with far less pollution caused by spray from the highway and runoff as compared to traditional asphalt.

Present-day worldwide water problems require new management tools and sustainable system innovations. At Delft University of Technology research is being carried out into water resources and management development aimed at forming such tools and innovations, focused on Integrated River Basin Management (IRBM). One of the case-studies deals with Dutch water management and technology in the context of European IRBM in the form of the 2000 Water Frame Directive. The Netherlands experience many water problems and European IRBM could bring help by offering a framework for both international cooperation and technological innovations. To work as an adequate management tool European IRBM should be tailored to the Dutch water tradition, which recently culminated in Integrated Water Management. Both approaches are in some respects contradicting. Europe pursues, for example, centralized control; while the Dutch have their strongly water boards based decentralized administration. The tensions between both approaches require mutual adaptation, for which the concept of subsidiarity might offer points of departure. This paper describes the first results of the case-research into Dutch water management and technology in the context of Europe as well as the backgrounds and the set-up of the research as a whole.

Abstract Background Evidence suggests that implementing an accountability mechanism such as the accountability framework for routine immunization in Nigeria (AFRIN) will improve routine immunization (RI) performance. The fact that the AFRIN, which was developed in 2012, still had not been operationalized at the subnational level (Ebonyi State) by 2018 may in part account for the poor RI coverage (33%) in 2017. Knowledge translation (KT) is defined as the methods for closing the gaps from knowledge to practice. Policy briefs (useful in communicating research findings to policy-makers) and policy dialogues (that enable stakeholders to understand research evidence and create context-resonant implementation plans) are two KT tools. This study evaluated their usefulness in enabling policy-makers to contextualize AFRIN in Ebonyi State, Nigeria. Methods The study design was cross-sectional descriptive with mixed-methods data collection. A policy brief developed from AFRIN guided deliberations in a 1-day multi-stakeholder policy dialogue by 30 policy actors. The usefulness of the KT tools in contextualizing policy recommendations in the AFRIN was assessed using validated questionnaires developed at McMaster University, Canada. Results At the end of the policy dialogue, the policy options in the policy brief were accepted but their implementation strategies were altered to suit the local context. The respondents’ mean ratings (MNR) of the overall usefulness of the policy brief and the policy dialogue in contextualizing the implementation strategies were 6.39 and 6.67, respectively, on a seven-point Likert scale (very useful). The MNR of the different dimensions of the policy brief and policy dialogue ranged from 6.17 to 6.60 and from 6.10 to 6.83, respectively (i.e. moderately helpful to very helpful). Conclusion The participants perceived the KT tools (policy brief and policy dialogue) as being very useful in contextualizing policy recommendations in a national policy document into state context-resonant implementable recommendations. We recommend the use of these KT tools in operationalizing AFRIN at the subnational level in Nigeria.

The real-time water quantity management of complex water resources systems can be successfully supported by mathematical models. Since there were no models available for integrated water management on the catchment scale, a generally applicable model system for quantitative water management has been developed and adapted to the watershed of the River Ruhr in Germany. The first results attained with this model system in the Ruhr catchment basin show that it is a powerful tool for operational water quantity management and is able to simulate a differentially structured watershed with high anthropogenic impacts. The use of this model has enabled Ruhrverband to make crucial improvements and increase the objectivity of operational water quantity management.

An important part of the landscape of irrigated areas in Tunisia is the result of morphology, organization and operation of agricultural policies implemented since independence, aimed at optimizing the exploitation of the best soils and natural resources, particularly water and productive crop intensification. The sustainability of the landscape of public irrigated areas has a strong bonding with the resources of irrigation water and their states of management. The scarcity of irrigation water due to drought generates profound changes in many public irrigated areas as Chott-Mariem and Mornag, like standpoint operating (decrease of production) and land occupation (transformation of agricultural land to urban land). An investigation was carried out with farmers, leaders and policy makers, which the result was a range of measures and recommendations to promote sustainability of agricultural landscape.

<p><em>Policy making is an integral part of policy studies. Theoretically the process of developing a policy document is neither easy nor simple. Far from merely copying the policy provisions of other countries, the process of developing a policy document must go through specific steps and procedures commonly known as policy cycle with each cycle serves specific functions. Although bench-making study is highly encouraged, it is also preferable for policymakers to align the policy making exercise in accordance to proven theory, model, method and process. Not many know about all these processes and steps. Some very senior and seasoned policymakers even think that there is no need for them to learn and pursue knowledge in policymaking simply because they have long years of practical experiences in developing, formulating, implementing, enforcing and subsequently analyzing and evaluating policies. This article reports case studies involving five national policy documents and internal policies at several key governmental department and organizations. The findings from the study enables the researchers to make a comparison between the theory of policy making and the practice of policy making in Malaysia. The findings show that there is still a huge gap between theory and practice in policymaking and policy studies in Malaysia. There are instances where few policy makers or top management personnel choose not to follow or ignorant about the steps of policy cycles. Although policy studies might have a very bright future in Malaysia but the journey in educating relevant parties would be a long one beginning with a correct perception and willingness to change attitudes.    </em></p><p> </p><strong>Keywords; <em>policy studies, policy cycle, policy making process</em></strong>
