A multi-actor analysis approach in decision making: A framework to complement ISA-95 guidelines within manufacturing companies
No full textDecision making in manufacturing activities is an everyday business. Manufacturing activities involve the interaction of different actors (i.e. departments) to provide information or activities that will serve as an input for decision making. The situation of dependency, network and cooperation in these activities calls in to question the suitability of today´s decision making processes, which more than enough do not actively and effectively include the several involved actors. A framework of a decision making process based on a multi-actor analysis approach was created and tested in manufacturing companies. This framework process proved with quicker and more effective decisions and suggests to have the potential to have great added value and more benefits to the companies using it. The thesis suggests that indeed, including the involved and affected actors at all stages of decision making, increases the chances to have succesful decisions and improves the support and better implementation of those decisions. The framework can be improved in several areas, most notably, by more empirical tests and research in different manufacturing companies among different regions.Engineering and Policy AnalysisPolicy AnalysisTechnology, Policy and Managemen
Minimum design requirements for domestic rainwater-harvesting systems on small volcanic islands in the Eastern Caribbean to prevent related water quality and quantity issues
No full textRainwater harvesting is the primary source of fresh water on the majority of isolated and volcanic islands in the Eastern Caribbean island chain that lack reliable sources fresh water. Recent research studies have determined that the microbiological quality of rainwater in cistern systems is generally unstable and can lead to serious health implications when used for human consumption. Another related issue is that rainwater shortages occur more frequently due to fluctuating rainfall patterns and increasing rainwater consumption rates. In this paper minimum design requirements are determined, using data from the islands of Saba and St Eustatius, for the construction of new domestic rainwater systems on small volcanic islands in the Eastern Caribbean. These minimum design requirements can be used to prevent potential water quality and quantity issues. One of the conclusions of this research study is that mainly the collection and storage elements of rainwater systems need to be constructed using non-toxic and non-corrosive materials to mitigate potential health risks. Also, first-flush devices need to be installed in the collection system to divert the mostly contaminated first load of rainwater after a dry period. The storage tanks need to be watertight and protected from sunlight, preferably located at least 30 meters away from active bacterial sources (such as open street sewers or cesspits). The minimum rainwater catchment area for a standard rainwater system, based on a 4-person family with a modern water consumption pattern, is 113m2; the minimum cistern storage capacity is 24m3.Policy AnalysisMulti Actor SystemsTechnology, Policy and Managemen
Climate change, water stress, conflict and migration: Taking stock of current insights through a vulnerability lens
No full textThere is a growing awareness in international policy circles that climate change may be a driver of increased migration flows. In addition to political refugees and economic migrants, climate change-induced migration and environmental migrants are increasingly recognized as categories in human migration. As climate change-induced migration is a relatively new phenomenon, there is little established policy or legislation on how to deal with the associated pressures and how to address the needs and rights of environmental migrants. International decision-making on climate change and its impacts would need to address these new emerging issues.Multi Actor SystemsCivil Engineering and Geoscience
Towards a design for an improved drinking water supply system on Bonaire, St Eustatius and Saba
No full textIn 2008, the author has conducted a research study on behalf of the Caribbean Water Association on the consequences of the constitutional change of the Netherlands Antilles for the drinking water supply on Bonaire, St Eustatius and Saba (BES). This research study formed the basis for further research in the form of this MSc. thesis. Being the responsible Ministry for the supply of drinking water on the future BES islands, VROM positively embraced the idea to study solution alternatives to improve the current situation on the BES islands. The Ministry of VROM granted the author with the financial means and support to conduct this thesis research study. In chapter 7 of this report a set of guidelines and instruments is presented that can support the Ministry of VROM in defining and preparing an improved drinking water supply on the BES islands.Sanitary EngineeringWatermanagementCivil Engineering and Geoscience
Actor analysis for water resources management: Putting the promise into practice
No full textWater related problems such as floods, droughts, declining groundwater tables or polluted rivers have a major impact on numerous societies throughout the world. Despite these serious problems, policy makers seem to make scant use of the knowledge that is available with water experts. Conversely, water experts face the task of finding out how they should position themselves to ensure that their analysis contributes to policy making. The task for those water experts is further complicated by the fact that water resources management involves various parties, called actors. Each actor has its specific position and responsibility in policy making, its own interests and objectives and its own perceptions of the main problems to be addressed. Actor analysis offers a potentially promising tool to support water experts, as it can be used to investigate the multi-actor policy making setting in which water experts find themselves. This is likely to help water experts design and execute analyses that are relevant to policy makers. Actor analysis for water resources management provides insight into how actor analysis is done in practice. A model-based approach for actor analysis is developed and its use is described for cases in Egypt, Turkey, the Netherlands and the Philippines. The results of these four cases are used to examine to what extent actor analysis lives up to its promise for water experts. The findings shed light on the use of actor analysis in practice and its potential to help water experts in their interactions with policy makers. Policy analysts and water experts alike may find the guidelines on executing an actor analysis valuable, and the examples of applications inspiring to their daily tasks.Technology, Policy and Managemen

Adaptief beleid en beleidsevaluaties
No full textEr is de laatste tijd veel aandacht voor het omgaan met onzekerheid en dynamiek in beleid. Zo is er recent de roep om leren door doen, door een overheid die samen met de samenleving het experiment aan durft te gaan. Zo’n benadering van beleid als gezamenlijk experiment is veelbelovend, maar vergt ook passende methoden voor beleidsevaluaties. Adaptief beleid speelt hierop in. De laatste jaren is een belangrijke stap gezet in de ontwikkeling van methoden waarmee adaptief beleid ontwikkeld kan worden. Voor de evaluatie en de rol van evaluaties heeft dit belangrijke implicaties. In dit artikel wordt hierop verder ingegaan, op basis van ervaringen met adaptief beleid en beleidsevaluatie binnen het Nederlandse Deltaprogramma.Policy Analysi
Assessment of nature-based flood defences' implementation potential: development and application of a game theory based method
No full textNature-based flood defence (NBFD) by means of vegetated foreshores is an innovative flood protection strategy. In contrasts with traditional hard structures it combines nature and flood protection functions and employs natural dynamics. Introducing such an innovation into actual flood protection projects requires not just proper understanding of the physical aspects of the approach. Equally important is the understanding of governance implications as NBFD decision-making implies involvement of different actors and actor interactions and requires alternative governance arrangements to enable implementation. Moreover NBFD implementation is far from self-evident; in fact most of the time traditional solutions are preferred. In this report we look into the actor interactions that are associated with NBFD and aim to improve understanding of NBFD implementation in flood defence projects. For that purpose we develop and apply a game theory based research approach. The objective is to: 1) systematically describe actor interactions in NBFD decision-making and the benefits of potential actor coalitions in NBFD projects; 2) identify exemplary NBFD games; and 3) understand solutions to the NBFD games and factors that may foster NBFD implementation. The approach is applied it three Dutch NBFD case studies: the Sand Engine, Markermeer dikes and the Afsluitdijk
Electric Mobility: On the Road to Energy Transition: A technical and actor assessment of social costs of electric mobility
No full textSeveral Dutch municipalities stimulate electric mobility by deploying a charging infrastructure. Electric mobility is however expected to impact the electricity grid, thereby requiring the grid to be reinforced. Costs for network reinforcements are social costs and it is in society’s benefit to limit those costs. Municipalities have no real incentive to limit grid impact in their charging infrastructure deployment strategies. Network operators have the incentives, but have limited means to minimise the impact. System analysis, network impact analysis and institutional analysis are done to come to technical and institutional options to limit the grid impact of electric mobility and deal with the skewed incentive structure. It is concluded that network operators should create a grid impact guideline for charging station deployment which indicates the grid capacity to deal with high power charging stations. This guideline can be used to create a municipal strategic charging station deployment map.Systems Engineering, Policy Analysis and ManagementEnergy and IndustryTechnology, Policy and Managemen
