We review the status of a 1.4 GW, 8 GWh underground pumped hydro storage (U-PHS) project in the southern Netherlands, which has been under development since the 1980s. Its history shows how the prospect of a large-scale U-PHS for The Netherlands (a country whose proverbial flatness prohibits PHS) has been attractive in every decade, based on proven technology in a subsurface location with validated properties, and solid analysis of its economics. Although the ongoing energy transition clearly requires massive electricity storage, (U-)PHS projects are challenging investment propositions, in The Netherlands, as elsewhere. This case study illustrates a point of general relevance, namely that although the project execution risk, related to uncertainty with respect to subsurface integrity, is very low, the transition risk, associated with the intrinsic uncertainties of an electricity system in transition, is significant. We point out mitigation strategies for both risk categories.

During the 2015 refugee crisis in Europe, temporary refugee shelters arose in the Netherlands to shelter the large influx of asylum seekers. The largest shelter was located in the eastern part of the country. This shelter, where tents housed nearly 3,000 asylum seekers, was managed with a firm top-down approach. However, many residents of the shelter—mainly Syrians and Eritreans—developed horizontal relations with the local receiving society, using social media to establish contact and exchange services and goods. This case study shows how various types of crisis communication played a role and how the different worlds came together. Connectivity is discussed in relation to inclusion, based on resilient (non-)humanitarian approaches that link society with social media. Moreover, we argue that the refugee crisis can be better understood by looking through the lens of connectivity, practices, and migration infrastructure instead of focusing only on state policies.

Abstract The purpose of this work is to develop a computationally efficient model of viral spread that can be utilized to better understand influences of stochastic factors on a large-scale system - such as the air traffic network. A particle-based model of passengers and seats aboard a single-cabin 737-800 is developed for use as a demonstration of concept on tracking the propagation of a virus through the aircraft's passenger compartment over multiple flights. The model is sufficiently computationally efficient so as to be viable for Monte Carlo simulation to capture various stochastic effects, such as number of passengers, number of initially sick passengers, seating locations of passengers, and baseline health of each passenger. The computational tool is then exercised in demonstration for assessing risk mitigation of intervention strategies, such as passenger-driven cleaning of seating environments and elimination of middle seating.

Celtic field research has so far been strongly focused on prospection and mapping. As a result of this there is a serious lack of knowledge of formation and land-use processes of these fields. This article describes a methodological case study in The Netherlands that may be applied to other European Celtic fields in the future. By interdisciplinary use of pedological, palynological and micromorphological research methods the authors were able to discern five development stages in the history of the field, dating from the late Bronze Age to the early Roman Period. There are strong indications that the earthen ridges, very typical for Celtic fields in the sandy landscapes of north-west Europe, were only formed in the later stages of Celtic field agriculture (late Iron Age and early Roman period). They were the result of a determined raising of the surface by large-scale transportation of soil material from the surroundings of the fields. Mainly the ridges were intensively cultivated and manured in the later stages of Celtic field cultivation. In the late Iron Age a remarkable shift in Celtic field agriculture took place from an extensive system with long fallow periods, a low level of manuring and extensive soil tillage to a more intensive system with shorter fallow periods, a more intensive soil tillage and a higher manuring intensity. There are also strong indications that rye (Secale cereale) was the main crop in the final stage of Celtic field agriculture.

Vector-borne diseases closely associated with the environment, such as leishmaniases, have been a usual argument about the deleterious impact of climate change on public health. From the biological point of view interaction of different variables has different and even conflicting effects on the survival of vectors and the probability transmission of pathogens. The results on ecoepidemiology of leishmaniasis in Argentina related to climate variables at different scales of space and time are presented. These studies showed that the changes in transmission due to change or increase in frequency and intensity of climatic instability were expressed through changes in the probability of vector-human reservoir effective contacts. These changes of contact in turn are modulated by both direct effects on the biology and ecology of the organisms involved, as by perceptions and changes in the behavior of the human communities at risk. Therefore, from the perspective of public health and state policy, and taking into account the current nonlinear increased velocity of climate change, we concluded that discussing the uncertainties of large-scale models will have lower impact than to develop-validate mitigation strategies to be operative at local level, and compatibles with sustainable development, conservation biodiversity, and respect for cultural diversity.

Realizing the importance of practicing environmental concern, it is needed to understand the tools used to tackle the issues. In this study, university – industry – policy (U-I-P) entities collaboration is a significant approach that was viewed to be the success factor towards the efforts of tackling environmental issues. Collaboration work, which involves different entities benefit in a way that pushes the entities to move towards shared objectives and goals which is to improve the environmental condition. However, although the significance of U-I-P entities collaboration was known and the linkages among U-I-P entities has started, there are still limited information on the practice of collaboration specifically on the U-I-P entities linkage structures on environmental matters in Sarawak. Thus, there is a need to identify the barriers and success factor in order to develop successful collaboration. This study addressed the gap through a mixed method of qualitative and quantitative approaches which the data were collected from 199 respondents based on a face to face interview using structured questionnaires in the major divisions of Sarawak. Drawing from a large scale of study, the study explores the status of collaboration and the barriers of collaboration in Sarawak. Findings indicated that cost, private knowledge and knowledge barrier to be a major hurdle that inhibit the development of collaboration. The assessment suggested that more efforts to increase awareness on collaboration be disseminated.

The supply chain risk management (SCRM) is very critical to strategically support the firms to continuous success. There are, at least, three basic steps in this SCRM process: risk identification, risk evaluation, and risk mitigation (treatment). Whatever happens, the main step is risk mitigation (RM) and mainly sustainable RM. In fact, every risk must be eliminated or controlled as much as possible. The purpose of this paper is to elaborate and evaluate various RM scenarios from an initial risk identification and prioritization solution. The proposed scenario modeling technique is based on morphological analysis (MA) as an explorative scenario tool for RM. MA is used to develop a framework to proactively assess critical risk variables. Firstly, MA is employed to exhaustively create possible RM scenarios and, secondly, to assess the likelihood of each scenario. The proposed approach addresses the need for a basic rubric to help identify and choose RM approaches. A real case study is provided from the food industry to illustrate the application of the proposed approach. To handle all possible MA strategies, a dedicated MORPHOL software package is used. In addition, RM strategies are selected based on sustainability indicators. The case study results prove that MA has a considerable value for SCRM. It shows that firms can adopt multiple robust strategies in the form of a scenario describing all stages of SCRM in an integrated representation.

Using a planning process for the Stuttgart Neckar Valley as a case study, this paper analyzes the urban inertial forces that counteract the transformation of energy infrastructure areas in the context of the energy transition. In order to overcome these forces, a scenario-based mission statement was developed in which spatial scenarios were derived from energy scenarios and finally summarized in a concept plan for the Neckar Valley. The mission statement was developed following an analytical-deliberative and transdisciplinary approach. The approach to mission statement development presented here can respond flexibly to changing framework conditions and thus serve as a model for other cities with large-scale energy infrastructures in transition.

Abstract Reduction of CO2 emissions has become a key component of many E&P company strategies, reflecting the accelerating demands of interest groups, activist investors, and country specific legislation for specific targets and measures of carbon footprint reduction. Underlying this requirement for change are the existing investments and cash flows resulting from the core ‘conventional’ business opportunities, that while potentially carbon heavy generate the cashflows needed to sustain and grow the business. Our work with several major energy firms has shown that assumptions and decisions impacting the pace of needed change need to be carefully tested, as many of the optimal decisions are counter intuitive. An example at a large integrated company was the insight that expansion of its shale resource investments accelerated the transition to a lower carbon footprint, given the cashflow generation and potential to advance low carbon alternatives in parallel. A portfolio model has been developed that replicates many of the options a company might assess in developing a strategy for carbon reduction and energy transition. This includes estimations of carbon generation from existing businesses as well as carbon reducing strategies ranging from carbon capture to new clean energy sources such as wind, solar, or hydrogen. A case study is used to represent the existing performance delivery and expectations for a large, integrated oil firm as it ‘transitions’ into a cleaner, low-carbon company. This modelling provides a window into the complexity of timing trade-offs, criticality in specific early investments, and drivers to the decisions surrounding a transitional business. The impacts of stasis, premature ‘forced’ transition, and errors in new clean energy ‘bets’ are assessed and tested, providing insights into risk mitigation strategies and alternatives. The case study clarifies the complexity in trade-offs within what appears to be a ‘simple’ energy transition strategy. This highlights the value and insights resulting from quantitative modelling of these decision structures. This paper provides examples of current methods of quantifying and assessing carbon reducing strategies. As the actual costs of generation depends on political considerations and societal demands, a wide range of typical company assumptions is outlined. In assessing alternative sources, the paper outlines the related ‘costs’ in the most touted clean-energy alternatives, both in the costs of implementation as well as the possible costs or charges resulting from future carbon generation. While most integrated energy companies have considered carbon reduction within their strategic plans for many years now, the investments in carbon reduction are for the most part negligible in comparison to conventional investments. International attention to carbon reduction and changes in societal expectations are putting additional pressures on companies to adapt more rapidly. However, transition introduces additional uncertainty, as seen by the possibility of a reduction in the credit ratings of some companies. Planning and understanding the proposed path is key to success.
