Ecosystem accounting - Natural capital - Netherlands - SEEA
In 2012, the Netherlands started the testing and production of high resolution, national scale ecosystem accounts following the methodology of the System of Environmental Economic Accounting – Experimental Ecosystem Accounting (SEEA EEA), in short ‘ecosystem accounting’. The SEEA is endorsed by the United Nations Statistical Commission as a comprehensive system for analysing and recording physical and monetary information on ecosystems and human dependencies on ecosystems. Many other countries have been developing natural capital accounts following the SEEA EEA, but the Netherlands work was novel in the sense that a comprehensive set of accounts has been developed for the whole country, including high resolution maps and accounting tables of ecosystem type, condition, services, assets, carbon and biodiversity. The work involved over 10 man-years of work, and was carried out in a collaboration by the Netherlands Statistical Office (CBS) and Wageningen University. This paper presents the methodologies followed and results obtained, and reflects on the policy applications of the accounts. Some further testing and development of the SEEA EEA is needed and also the Netherlands accounts are not yet complete. Nevertheless, the lessons learned in the Netherlands are relevant for other accounting efforts world-wide.

Door intensivering en schaalvergroting in de landbouw is de ruimte voor natuur op het platteland flink afgenomen en is het landschap eentoniger geworden. We weten eigenlijk heel weinig van wat de Nederlandse bevolking daarvan vindt, terwijl maatschappelijke steun cruciaal is voor initiatieven om biodiversiteit te vergroten, zowel publiek als privaat. In dit artikel verken ik hoe belangrijk natuur op het platteland wordt gevonden en hoe de waardering van boerennatuur kan worden versterkt.

Offshore wind farms in the Dutch North Sea must make demonstrable efforts to stimulate native nature within the wind farm. For example, suitable scour protection or fish hotels can be placed around wind turbines that serve as nursery areas or offer shelter. Also flat oysters can be placed, which can form reefs and attract great biodiversity. Commissioned by the Ministry of Agriculture, Nature and Food Quality, Witteveen+Bos and Wageningen Marine Research have produced a catalog of such Nature Inclusive Design options. The catalog shows the target species for which the option is suitable, the expected construction costs, and where the materials can be purchased.

community innovation survey - Employment - industry - innovation - labour productivity - Netherlands
This article examines the relationship between firm-level innovation and employment growth for industrial firms in the Netherlands. The empirical analysis uses four waves of the CIS survey for the period 2002-2010. It extends the literature by making an explicit split between the expansion effect of innovation and the labour productivity effect. The results show that both product and process innovation increase labour productivity and therefore induce direct reductions in employment. However, these negative employment effects are more than compensated by increases in sales, implying that both process and product innovations increase employment. In this article for the first time the relationship between both product and process innovations and employment is decomposed in a systematic manner based on explicit econometric equations on the relationship between innovation and labour productivity respectively sales. It is argued that the effects for sales and labour productivity are probably underestimated in all research that uses CIS survey data because these do not show the price effects of increased productivity, but that this effect cancels out in the estimated employment equation.

agricultural water management - Local water storage - Netherlands - scale issues - storage feasibility
The regional effects of local water storage are largely unknown. This study identifies, categorizes and discusses the challenges in assessing the potential of local water storage. These are illustrated using a structured method applied to a Dutch case. We conclude that the focus must shift from storage ‘potential’ (the quantity of water that can be stored) to storage ‘feasibility’, which depends on exploitability, purpose and interactions between storage alternatives. Spatial and temporal scale also influence feasibility. Finally, farmers’ investment preferences are a factor, though these are shrouded in uncertainty. This overview is a first step towards improving storage assessment tools and processes.

disaster risk reduction - Flood risk communication - lay knowledge - Netherlands
Many urban residences are insufficiently prepared for fluvial, pluvial or coastal floods, owing to a lack of accurate information on flood risk. This article analyzes how risk communication can improve disaster risk reduction by overcoming the expert–layperson gap. Building on interviews in three cities in the Netherlands, it applies Q methodology to identify four perspectives on flood risk communication. To promote greater private residential involvement in flood risk adaptation, communication should address all four rationalities.

good governance - Netherlands - OECD - river basin - Water governance - water management
The past two decades have witnessed increasing global concern about the need for sustainable water and land management in an era of rapid change, and persistent water insecurity. Good water governance is a prerequisite to improve water management all over the world. The OECD Water Governance Initiative developed Water Governance Principles to enhance the process from water policy design to implementation. This contribution aims to examine how the OECD Water Governance Principles fit actual water governance on the local scale. Therefore a Dutch case is employed here to almost serve as a benchmark test for the framework of the OECD water governance principles.

Netherlands - Sky view factor - UHI - Urban planning
The sky view factor (SVF) is essential to describe the urban climatology at scales below 100m. This proxy for net radiation depends on the height of the obstacles in its surroundings. The SVF was calculated from a rasterized point cloud height dataset (with 6 − 10 points per m2). The resulting SVF depends on grid-resolution, search radius and number of directions. Previous research related the diurnal maximum urban heat island (UHI) of the canopy layer to the diurnal temperature range, solar irradiance, wind speed, vegetation fraction and SVF. The goal of this study is to determine the sensitivity of the SVF and the impact on the UHI. Within the Netherlands a test area of 70km2 was selected, including: urban areas, meadows and forests. There is a high sensitivity for grid-resolution. Therefore the impact of the SVFs grid resolution on the maximum UHI is explored. Results show that the fourth largest city within the Netherlands, Utrecht, has a mean diurnal maximum UHI of 3.1 °C using a 1m SVF resolution. But, with a 3m SVF resolution the UHI is on average 0.6 °C lower. This highlights the significance of a fine grid resolution which can capture houses, alleys and trees.

Rabbit haemorrhagic disease virus (RHDV) type 2 (GI.2/RHDV2/b) is an emerging pathogen in wild rabbits and in domestic rabbits vaccinated against RHDV (GI.1). Here we report the genome sequence of a contemporary RHDV2 isolate from the Netherlands and investigate the immunogenicity of virus-like particles (VLPs) produced in insect cells. RHDV2 RNA was isolated from the liver of a naturally infected wild rabbit and the complete viral genome sequence was assembled from sequenced RT-PCR products. Phylogenetic analysis based on the VP60 capsid gene demonstrated that the RHDV2 NL2016 isolate clustered with other contemporary RHDV2 strains. The VP60 gene was cloned in a baculovirus expression vector to produce VLPs in Sf9 insect cells. Density-gradient purified RHDV2 VLPs were visualized by transmission electron microscopy as spherical particles of around 30 nm in diameter with a morphology resembling authentic RHDV. Immunization of rabbits with RHDV2 VLPs resulted in high production of serum antibodies against VP60, and the production of cytokines (IFN-γ and IL-4) was significantly elevated in the immunized rabbits compared to the control group. The results demonstrate that the recombinant RHDV2 VLPs are highly immunogenic and may find applications in serological detection assays and might be further developed as a vaccine candidate to protect domestic rabbits against RHDV2 infection.

Acoustics - Beach - Broad Acoustic Resonance Dissolution Spectroscopy - Netherlands - Provenance - Resonance - Sound spectroscopy
In this study, we examine sand from the Dutch shores to link its unique acoustic traits to the source of the sand. Sand from nine locations along the beaches of the Netherlands, over a stretch of 187 km, were collected and subjected to Broad Acoustic Resonance Dissolution Spectroscopy analysis (BARDS). Sand sampling positions with respect to the distance to the high water line were compared as well. Temporal acoustic profiles, resulting from gas released from the sand particles in an acidic solution over time, were used to compare the sands from the various locations and positions along the shore. These BARDS patterns were compared with those of model sand samples composed of CaCO 3 , CaCO 3 /quartz mixtures, and ground sea shell/quartz mixtures to understand the phenomena. BARDS analysis allowed accurate measurements of the unique acoustic traits of the sands, which appeared good indicators of the source of the sand. The results show that both the composition and morphology of the sand determine the acoustic profiles. The proportion of seashells in the sand plays an important role in the acoustic signatures of the sands of the Dutch shores. The carbonate components of the shells and the shells’ morphology result in dissolution of the carbonates under acidic conditions and subsequent release of CO 2 in specific patterns. These specific patterns allow us to establish the source of the sand – with help of multivariate statistical methods. Evidently, the current study shows that ‘listening’ to the sound of sand reveals interesting information about its identity and origin.

Co-carriage - ESBL/AmpC - Escherichia coli - Household - Insertion sequence - Netherlands - Plasmid
Extended-spectrum cephalosporin-resistant (ESCR) Enterobacteriaceae pose a serious infection control challenge for public health. The emergence of the ESCR phenotype is mostly facilitated by plasmid-mediated horizontal extended-spectrum β-lactamases (ESBLs) and AmpC gene transfer within Enterobacteriaceae. Current data regarding the plasmid contribution to this emergence within the Dutch human population is limited. Hence, the aim of this study was to gain insight into the role of plasmids in the dissemination of ESBL/AmpC genes inside Dutch households with preschool children and precisely delineate co-colonization. In 87 ESCR Enterobacteriaceae from fecal samples of parents and preschool children within 66 Dutch households, genomic localization, plasmid type and insertion sequences linked to ESBL/AmpC genes were determined. Chromosomal location of ESBL/AmpC genes was confirmed when needed. An epidemiologically relevant subset of the isolates based on household co-carriage was assessed by Multilocus Sequence Typing and Pulsed-Field Gel Electrophoresis for genetic relatedness. The narrow-host range I1a and F plasmids were the major facilitators of ESBL/AmpC-gene dissemination. Interestingly, we documented a relatively high occurrence of chromosomal integration of typically plasmid-encoded ESBL/AmpC-genes. A high diversity of non-epidemic Escherichia coli sequence types (STs) was revealed; the predominant STs belonged to the pandemic lineages of extraintestinal pathogenic E. coli ST131 and ST69. Intra-familiar co-carriage by identical ESCR Enterobacteriaceae was documented in 7 households compared to 14 based on sole gene typing, as previously reported. Co-carriage was more frequent than expected based on pure chance, suggesting clonal transmission between children and parents within the household.

Climate change adaptation - Netherlands - Water boards - Water management plans - Water policy
The Netherlands is particularly vulnerable for the impacts of climate change on the water system. Regional water authorities, or water boards, are given an important role to design and implement specific adaptation policies and measures to manage these impacts. From the early 2000s onwards water boards are starting to adapt to climate change impacts, yet no systematic assessments exist to assess whether or not progress is being made and what explains similarities and differences across water boards. This paper aims to address these critical questions by analyzing the progress of all Dutch water boards for the period 2005–2016. We systematically collected and analyzed three consecutive water management plans for all 23 water boards in the Netherlands. We use content analysis methods to analyze progress by looking into their vulnerability and three levels of adaptation: recognition, groundwork and adaptation action. The results show that over time the number of reported climate change adaptation initiatives by the water boards is increasing, but most climate change adaptation is still at the recognition or groundwork level. Our findings reveal a diversity of efforts to adapt to climate change among Dutch water boards. We conclude that while (inter)national water and climate change adaptation policies have called for more adaptation action at regional levels, the unequal progress across the Netherlands suggests that existing ‘soft’ policy measures to push for adaptation might not be sufficient to ensure progress on adaptation across all water boards.

Institutions - Netherlands - State formation - Water management
For early modern societies, distributing the costs of flood defences between the stakeholders in an equitable way was difficult. Institutions were abused by powerful groups to shift the financial burden to poorer groups. According to Epstein, such elite abuse of institutions was possible because in pre-modern states political and economic power were not separated, which made it possible for elite groups to hijack the decision-making process. By studying how three ‘states’ in the South-Western Netherlands distributed the high costs of dike maintenance, this paper partly confirms Epstein’s thesis. No separation existed between political and economic power in the province of Zeeland and here this caused a stalemate because cities represented in the provincial government protected their elites’ interests. In Holland and the territories of the States-General, however, taking quick and efficient measures for the repair and financing of sea defences was possible. Here the powerful cities had less significant interests in the areas concerned and were prepared to leave decision- making to technical and financial experts.

Daly - Netherlands - Pigs - Serological surveillance - Toxoplasma gondii
Toxoplasma gondii (T. gondii) is a food safety hazard which causes a substantial human disease burden and cost-of-illness. Infected pig meat is a common source of toxoplasmosis. A break-even analysis was conducted to estimate the point for which the intervention cost at fattening pig farms equaled the cost of averted human disease burden and cost-of-illness minus the costs of a T. gondii surveillance program. The surveillance program comprised serological testing of blood samples taken at slaughter. Break-even points were determined given alternative levels of the effectiveness of the intervention program (10% up to 90% in steps of 10%), the value of an averted DALY (20,000, 50,000 and 80,000 Euro), and threshold of sample prevalence for a farm to be under intervention (5% up to 50% out of 20 samples in steps of 5%). Since test characteristics are a determining factor in the break-even analysis, and literature is inconclusive concerning sensitivity (se) and specificity (sp) of the serological test kit used, two alternative sets of assumptions were analysed. The estimated maximum costs of an intervention if only benefits for domestic consumers were accounted amounted approximately 2981 Euro (se = 98.9% and sp = 92.7%) versus 4389 Euro (se = 65.2% and sp = 97.4%) per year per fattening pig farm under intervention assuming an effectiveness of 50%, 50,000 Euro per averted DALY and threshold T. gondii sample prevalence of 5% for a farm to be under intervention. Since almost 80% of the gross domestic production is exported corresponding break-even values increased up to 12,034 Euro and 18,366 Euro if benefits for consumers abroad were included as well. Empirical research to strengthen the knowledge about the efficacy of a farm intervention measures is recommended.
Ideal versus reality? The domesticity ideal and household labour relations in Dutch industrializing regions, circa 1890

domesticity - Labour relations - Netherlands - nineteenth century - women’s work
For long, international comparisons of female labour force participation (FLFP) have been based on aggregate source material, most notably censuses. However, the lion’s share of today’s historians agree that censuses have systematically underreported women’s work activities. Consequently, scholars relying on this source have found a nineteenth-century Dutch male breadwinner society while others have found that the Dutch female labour force was quite extensive. This discrepancy in the historiography is in need of closer scrutiny. The current study shows that by the end of the nineteenth century, in industrial regions married women indeed withdrew from the registered labour market but instead engaged in other types of labour relations that could easily be combined with homemaking duties and that remained invisible in the census. Furthermore, this article argues that the fact that married women provided an income did not necessarily contradict the growing ideal of domesticity. The alternative types of work married women took up were rather a way of reconciling this ideal with keeping the household on a respectable level of existence.

Experience - National identity - Netherlands - Second World War - Social identity theory - Warfare tourism
This paper examines through an analysis of Dutch warfare tourism whether there is a relationship between the subjective perceived salience of Dutch identity and heritage tourists’ motives, emotions and overall satisfaction. Using a social identity theory framework, this study provides a view of motives for Dutch warfare heritage tourism and the ways in which this specific variant of heritage tourism evokes different emotions and satisfaction evaluations in visitors. Specifically, we found that visitors who identified strongly as ‘being Dutch’ (the ‘in-group’) have stronger self-enhancement motives compared to those who identify less strongly, and that edutainment features strongly in the museum experience. Visitors seeking initiative/recognition express feelings of disappointment suggesting that the museum's symbolic function as a place of national in-group identity could be more highlighted. We demonstrate that an affirmative and engaged experience can manifest at nationally symbolic sites through positive historical narratives and entertainment, and through ‘in-group’ self-enhancement activities.

Governance - Implementation - Netherlands - Planning - Spatial strategy
The Dutch planning system has been widely feted as a coordinated, 'plan-led' and evidence-informed system that has been successfully implemented, resulting in sensitive land management, an absence of urban sprawl and the protection of 'green areas'. However, at least since the 1970s, the reality has been somewhat different. This paper reviews Dutch planning history over the past fifty years to highlight in particular the challenge of implementation. The paper also reviews the current challenges facing Dutch planners and provides some international reflection from Dutch experiences for Irish planners.
