This report presents the result of an online survey amongst key-stakeholders involved in the management planning and management of Natura 2000 sites in in England, Flanders, France and the Netherlands. The survey was held in a total of 91 sites and resulted in 464 (fully or partially) completed surveys (response rate was 20%). Overall, the results of the survey indicate that perceptions of actors in the area differ among actor groups, especially in regard to statements that measure impacts or value judgements. This result underlines the importance of including a broad range of stakeholders in the policy evaluations of the management of the area. Overall, the differences between the geographical areas are small, except on topics related to the discussion between the government and involved stakeholders were a moderate difference was found. Also the status of prior designation has a small effect on how respondents view the discussion on management.

horticulture - greenhouse horticulture - greenhouse technology - diffused glass - light transmission - condensation - glass - agricultural research - netherlands - belgium - coatings - scattering - roofs

Growers know that a diffuse roof – with or without an anti-reflective coating – offers added value compared with traditional greenhouse glass. However, it is not so simple to decide which one to choose. Researcher Silke Hemming lists all the relevant aspects. An underestimated factor is measuring samples taken from good representative spots for new large-scale building projects.

Nephropathia epidemica (NE) is a human infection caused by Puumala virus (PUUV), which is naturally carried and shed by bank voles (Myodes glareolus). The objective was to develop a dynamic model of the NE cases and the bank vole population in both Finland and Belgium by defining the periodic components with a dynamic harmonic regression (DHR) model. The defined periodic components can be further used to adapt mechanistic Susceptible and Infective (SI) models regionally. Despite the difference in bank vole population dynamics and NE cases between the Western European temperate zone and boreal zones the DHR model was able to quantify the dynamics of NE cases in Belgium and Central Finland with a coefficient of determination (R2) of 0.70 and 0.82 respectively and to quantify the dynamics of bank vole population in Belgium and Central Finland with R2 of 0.80 and 0.98 respectively. DHR identified 18 month cycles in the bank vole population in Belgium. This approach demonstrated two year cycles in Belgian NE outbreaks. DHR identified three year cycles in Finnish bank vole populations which in turn cause three year cycles in the NE outbreaks in Central Finland. Because the bank vole population data in Finland was contemporary with the data of NE cases, the DHR showed a three month delay between the NE cases and the bank vole population in Central Finland. This approach may help us in our understanding of the spatial and temporal dynamics of NE cases and the bank vole populations in different regions.

Scientific knowledge about ecosystem services is rapidly being translated into policy objectives, and several EU member states have included ecosystem services in their policy programmes. However, stakeholders are experiencing many problems applying such policies in rural areas. This WOt paper describes early experiences with the ecosystem services approach in terms of opportunities and barriers. It also formulates alternative application pathways that could be supported by the many stakeholders involved.

Zinc is an essential trace element for all farm animal species. It is commonly included in animal diets as zinc oxide, zinc sulphate or organically bound zinc. Umicore Zinc Chemicals developed zinc oxide products with different mean particle sizes. Umicore Zinc Chemicals requested Wageningen UR Livestock Research to determine the bioavailability of four zinc oxide sources and zinc sulphate in broiler chickens. A precise estimate of the bioavailability of zinc sources is required both for fulfilling the zinc requirements of the animal and to reduce zinc excretion in excreta and the environment.

In 2013 traces of perchlorate were detected in fruits and vegetable samples. Because perchlorate (ClO4 -) is part of a group of substances (goitrogens) that may inhibit the uptake of iodine by the thyroid, these findings caused commotion in the markets. Fertilizers were named as one of the sources of perchlorate in food. Therefore, at the request of the fertilizer industry, research has been conducted on perchlorate uptake and distribution in the most relevant greenhouse vegetable crops in Belgium and the Netherlands.

Purpose – The purpose of this paper is to investigate the preferred minimum level of segregation for halal meat in supermarket, transport, storage and terminals; the responsibility of halal logistics; and the willingness to pay for halal logistics in a Muslim and non-Muslim country. Design/methodology/approach – This is a comparative study involving Muslim consumers in Malaysia and The Netherlands. Cross-sectional data were collected through a survey with 251 Muslims in Malaysia and 250 Muslims in The Netherlands. Data were analysed by means of nonparametric tests. Findings – There is a preferred higher level of segregation in a Muslim country than a non-Muslim country. A Muslim country has a higher willingness to pay for a halal logistics system as compared to a non-Muslim country. Furthermore, there lies a heavy responsibility with the manufacturer to extend halal assurance towards supply chain management. Research limitations/implications – The study confirms there is a need for a different level of segregation and therefore different halal logistics standard in a Muslim country and a non-Muslim country. However, during the survey in The Netherlands significant rejections were received from especially first generation Muslims due to the lack of understanding of the Dutch language. Similar surveys need to be conducted in other countries in order to be able to generalise over the various Islamic schools of thought, local fatwas and local customs. Practical implications – Halal logistics is important to the Muslim consumer and critical for the trust in a halal certified brand, which requires extending halal integrity from point of production to the point of consumer purchase. Originality/value – This study is a preliminary one investigating the consumer perception on halal logistics. The study indicates the level of segregation required for a halal meat supply chain in a Muslim and non-Muslim country.

While the right to adequate food is often discussed in the context of developing countries, especially in situations where access to adequate food is a problem on a larger scale, this book focusses on the right to food in two Western countries in which theoretically the circumstances allow this right to be enjoyed by each individual. Through a legal comparative study, the enforceability of the right to food is compared between the Netherlands and Belgium in light of the current UN Human Rights system. There seems to be a difference between what the countries do, what they say they do, and what they should do on the matter. As it appears, the coincidental constitutional circumstances mainly determine the enforceability of the right to food, rather than the content of the human right in itself. This book includes a thorough analysis of suitable comparative legal methodology and the embedment of the right to food in the UN human right system. Furthermore, for both countries, an in-depth analysis of the case law on the right to food (mostly concerning the status of foreigners), the constitutional context in which the Judiciary operates, and the relevant UN reports and subsequent procedures are outlined. Finally, recommendations are made to both countries and the relevant UN Committees.

Cylindrocladium buxicola (syn. C. pseudonaviculatum; teleomorph Calonectria pseudonaviculata) is an important fungal pathogen of Buxus spp. Although widespread in Western Europe, this pathogen has only recently been introduced into North America, where it represents a significant threat to the U.S. and Canadian boxwood industries. Trade of latently infected nursery stock is an important mode of long-distance dissemination and introduction of this pathogen but no methods for detection of latently infected material are available. Also, the pathways for short-distance dispersal of C. buxicola have not been adequately studied. Improved detection methods of this pathogen in air and water samples would benefit future research in this area. We have developed real-time polymerase chain reaction assays for the detection of C. buxicola based on the ribosomal DNA internal transcribed spacer 1 (ITS) and the ß-tubulin 2 gene (TUB). Using a TaqMan probe conjugated with a 3' minor groove binding group (TaqMan MGB probe), the ITS-based assay could reliably detect as little as 10 fg of genomic DNA or 20 copies of cloned target DNA and was approximately 70 times more sensitive than the SYBR Green TUB-based assay. The ITS-based assay provided good but not complete specificity, and is well suited for epidemiological studies. The TUB-based assay, however, proved to be fully specific and can be used for diagnostics. We developed and optimized sample processing and DNA extraction methods for detection of latently present C. buxicola in boxwood plants and quantification of conidia in water and air samples. C. buxicola could be detected in 20 g of plant material, of which only 1 ppm of the tissue was infected, in 10-ml water samples containing as low as 1 conidium/ml, and on Melinex tape pieces representing 12 h of air sampling containing 10 or more conidia. The applicability of the techniques to plant, water, and air samples of practical size was demonstrated.

The Black-tailed Godwit, Limosa limosa, is a near-threatened wader bird with a European breeding distribution that is concentrated in Western Europe. This report summarizes the legal aspects of Black-tailed Godwit conservation and gives a concise overview of the implementation and effectiveness of conservation action that is taken in Belgium, Germany and the Netherlands. In all three countries, conservation initiatives are rarely effective enough to halt the ongoing decline of the species, although there are successful local exceptions. The review concludes with the recommendation to formulate a coherent strategy for Black-tailed Godwit conservation starting with the identification of favourable reference values in each of the three countries
Colonial Exploitation and Economic Development: The Belgian Congo and the Netherlands Indies Compared

This volume discusses the comparative legacy of colonial rule in the Netherlands Indies and Belgian Congo during the nineteenth and twentieth centuries. Whereas the Indonesian economy progressed rapidly during the last three decades of the twentieth century and became a self-reliant and assertive world power, the Congo regressed into a state of political chaos and endemic violence. To which extent do the different legacies of Dutch and Belgian rule explain these different development outcomes, if they do at all? By discussing the comparative features and development of Dutch and Belgian rule, the book aims to contribute to a deeper understanding of the role of colonial institutional legacies in long run patterns of economic divergence in the modern era and to add a comparative case-study to the strand of literature analyzing the marked differences in economic and political development in Asia and Africa during the postcolonial era.

National-scale inventories of soil organic carbon (SOC) and forest floor carbon (FFC) stocks have a high uncertainty. Inventories are often based on the interpolation of sampled information, often using a number of covariables to help such interpolation. The rationale for the choice of these covariables is not always documented, despite the fact that many local-scale studies have identified the factors explaining spatial variability of SOC and FFC stocks. These studies indicate, among others the importance of long-term land use history. Despite this, information on the effects of land use history has never been used to explain variability of carbon stocks in national-scale inventories. We designed an alternative method to improve national-scale inventories of SOC and FCC for the Dutch sand area that takes stock of the findings of detailed case studies. Determinants for SOC and FFC stocks derived from landscape-scale case studies were used to map national-scale spatial variability and to calculate national totals. The resulting national-scale spatial distribution was compared with the SOC stock map from the current Dutch greenhouse gas inventory. Using land use history to explain SOC variability decreased the error of the SOC stock estimate in 60 % of the area. The error in FFC stocks decreased in half of the forest area after including soil fertility, tree species, and forest age as explanatory factors. Estimates with reduced uncertainty will make land use and land management a more attractive and acceptable mitigation option to reduce emissions of greenhouse gases for the LULUCF sector.
