Biogas - Digestate - Greenhouse gasses - Maize - Nitrogen - Static chambers

Digestate is considered a sustainable opportunity to reduce environmental impact from fertilization, due to high content of nitrogen easily available for plants and for the low impact of its production. We tested liquid fraction of digestate from anaerobic digestion of pig slurries and urea, to assess the emissions of nitrous oxide and ammonia from soil on silage maize (Zea mays L.). Nitrogen rate was the same for both treatments (150 kg/ha) spread replacing common methods. Emissions measurements were performed immediately after fertilization using a static chamber method with a portable gas analyser. Measurements were performed daily during the first week, and twice per week until no emissions from the soil were observed. Cumulative nitrogen emissions show that digestate can be an efficient method to reduce nitrogen losses (2.87 kg N/ha/25 days and 3.76 kg N/ha/25 days for digestate and urea respectively). However, the two fertilizers emitted different kind of gases: compared to urea, digestate emitted the 23% of nitrous oxide more, on the other hand urea emitted 66% of ammonia more than digestate. Crop yield obtained under the two fertilization methods did not significantly differ in terms of dry matter (DM) (13.63 t DM/ha and 13.24 t DM/ha for digestate and urea, respectively) (significance factor α > 0.5).

ObjectivesThe aim of this work was to examine the cross-sectional relationship between body composition (BC) markers for adipose and lean tissue and bone mass, and a wide range of specific inflammatory and adipose-related markers in healthy elderly Europeans. Methods A whole-body dual-energy X-ray absorptiometry (DXA) scan was made in 1121 healthy (65–79 years) women and men from five European countries of the “New dietary strategies addressing the specific needs of elderly population for a healthy aging in Europe” project (NCT01754012) cohort to measure markers of adipose and lean tissue and bone mass. Pro-inflammatory (IL-6, IL-6Rα, TNF-α, TNF-R1, TNF-R2, pentraxin 3, CRP, alpha-1-acid glycoprotein, albumin) and anti-inflammatory (IL-10, TGF-β1) molecules as well as adipose-related markers such as leptin, adiponectin, ghrelin, and resistin were measured by magnetic bead-based multiplex-specific immunoassays and biochemical assays. Results BC characteristics were different in elderly women and men, and more favorable BC markers were associated with a better adipose-related inflammatory profile, with the exception of skeletal muscle mass index. No correlation was found with the body composition markers and circulating levels of some standard pro- and anti-inflammatory markers like IL-6, pentraxin 3, IL-10, TGF-β1, TNF-α, IL-6Rα, glycoprotein 130, TNF-α-R1, and TNF-α-R2.Conclusions The association between BC and inflammatory and adipose-related biomarkers is crucial in decoding aging and pathophysiological processes, such as sarcopenia. DXA can help in understanding how the measurement of fat and muscle is important, making the way from research to clinical practice.

The Nutrition Researcher Cohort (NRC) was launched at the 10th NuGOweek 2013 and represents a new generation research platform. Thereby, each individual provides and owns her/his selfquantification data on her/his health data using various gadgets and/or clinical analysis. The NRC approach is thus in a stepping-stone ‘development phase’ for a new way to merge observational research, personal health empowerment, (nutritional) intervention studies and preventive healthcare with the goal to become a globally accepted standard. Thereby, the NRC aims to renew the relationship between research and healthcare. Participants actively take part in research studies, by monitoring their health status themselves, instead of being passive data-and-blood-donating humans. In addition, participants will have a direct health benefit from participating in research by personalized health information and advice based on their personal data. We here present the first results of the initiation study, which included metabolomics and metabolite profiling of Dried Blood Spots (DBS) of finger prick blood, accomplished by five participating laboratories. Furthermore, all participants were asked to enter self-quantification data on food intake, anthropometrics, age, blood pressure, glucose response and several more. In total, about 300 metabolites were identified and relatively or absolutely quantified using LC-MS/MS and GC-MS. In addition, four trace elements were determined using total-reflection X-ray fluorescence analysis. Metabolite profiles will be connected to self-quantification data, anthropometrics and food intake. Thereof, first examples of visualization will be presented. The final aim is to provide personal advice on health, lifestyle and diet. As the NRC is a ‘crowd or citizen science’ initiative, any lab is invited to participate in optimizing and supplying DiY sampling (e.g. DBS, mucosal swaps) and analytics, metabolomics, data visualization and interpretation or other relevant methods.

Abstract: Personalised nutrition is a relatively new field of research aiming to provide personalised dietary advice, which can be based on an individual’s genotype, phenotype, dietary and lifestyle data. According to this approach, dietary recommendations are tailored to meet personal nutritional needs. The goal of this analysis is to explore differences in perceived barriers to the uptake of personalised nutrition between consumers in different European countries. Data for this research were collected in February and March 2013, using on-line survey methodology. A total of 9381 participants from 9 European countries (Germany, Greece, Ireland, Poland, Portugal, Spain, the Netherlands, the UK, and Norway)participated. Perceived barriers for the adoption of personalised nutrition were measured using 18 items for which responses were on a five-point scale where respondents had to indicate their level of concern regarding various circumstances that could potentially prevent them from taking up personalised nutrition. Results showed significant differences between the 9 European countries in perceptions of barriers to the uptake of personalised nutrition. In some countries, like Greece, Spain and Germany, trust barrier was dominant while in other (e.g. Poland and Ireland) family and social barriers were deemed more important. This implies that policies targeted at promoting adoption of personalised nutrition need to be adapted for each country. Keywords: personalised nutrition, barriers, Europe
Scale-dependent synergy between risk management and open space preservation
Dijk, T. van - \ 2007
In: Planning for the Risk Society. Dealing with Uncertainty, Challenging the Future. Abstracts. - Napoli : Giannini Editore - ISBN 9788874313693 - p. 215 - 215.
In planning processes, we employ various morphological planning concepts that deal with how to divide urban land use and open space (green belt, green wedge, infill, compact city, ecological corridor). Although with such concepts we can envisage some geographical pattern, it is often not clear on what geographical scale this pattern should emerge. The issue of scale, however, is crucial to the way in which such a concept can actually be implemented; planning is interaction between people, and people have limited territorial attachment. Therefore, the scale on which a concept is implemented defines how many and what type of actors are relevant. For application on a higher level of scale (regional or national), the network of relevant actors becomes quite complex and hard to influence. Risk perception, in cases of large scale projection of a morphological concept may be a blessing because of its unifying effect. Within a context of risk management, relatively little contested strategies can be generated, unlike in case of pursuing sectoral ambitions. And a high risk could mean not developing the land at that location, synchronising ambitions for open space with risk management may yield synergy. This paper explores the potential for synergy between flood risk and open space preservation on a high level of scale in the Dutch context. It aims to illustrate and conceptualise this synergy by interlinking the concepts of scale, actor network and convergence of interests.
A genealogy of spatial concepts of the Dutch National Landscape Het Groene Woud

regionale planning - nationale landschappen - noord-brabant - regional planning - national landscapes
Het Groene Woud (GW), a rurban area in the Dutch province of Noord-Brabant, is designated as National Landscape by the national government. Consequently, the region has to develop a coherent vision for future decisions. This includes the identification of key spatial characteristics of GW. This is complex due to diverse (conflicting) spatial developments and initiatives, concerning nature, agriculture, recreation, urbanisation and cultural heritage. How to come to a set of `shared' spatial characteristics? Among other answers, this paper presents a genealogy of spatial concepts, being an overview of spatial concepts for GW of the last two decades. The story of concepts represents local geographical and political knowledge; namely, concepts contain the observed and (un)desired spatial characteristics - based on the situation and ambitions of a specific group, at a specific moment and at a specific scale. To construct a genealogy we investigate spatial concepts in several policy documents, project plans and newspaper reports. We emphasise the context of these concepts in order to distinguish trends and breakpoints in conceptualisation. For example, spatial conceptualisation of spatial issues - as urban-rural, nature functions or multi-functionality - has changed: what are backgrounds of these breaks? We also discuss the use of a genealogic method and the functions of spatial concepts for planning rurban regions
The meaning of flood risk information in spatial planning
Neuvel, J. ; Brink, A. van den - \ 2007

Spatial planning can be seen as one of the means to prevent and mitigate flood risks. To support the consideration of flood hazards within spatial planning processes, numerous GIS based models and systems have been developed. Since GIS based systems and models increase our insight in the chance and magnitude of flood risks, they increase opportunities to act upon them. Interestingly, what used to be seen as dangers (`acts of god') may now have become seen as risks (`errors of man'). By implication safety consequences are more and more attributed to decisions and can increasingly be seen as the consequences of choices made by decision makers. From this perspective, it becomes interesting to examine how decision makers deal with risk information and especially how decision makers give meaning to this information in their actions related to spatial developments, such as decision related to the choice of building sites or decisions about the necessity of (additional) safety measures. In the paper, this question will be discussed by the analysis of a case in the Netherlands where spatial developments are proposed in a flood prone area. The results have been derived from a policy analysis based on desk research and interviews with governors and representatives from water boards and spatial planning departments at the provincial and municipal level.
Reflection on planning practices: an important aspect of planning education

Planning education often has a strong focus on knowledge, methods, and tools about how to plan. However, spatial planning is also about studying and reflecting on planning practices. The ability to reflect critically on planning practices enhances the students’ capability of understanding planning practices and consequently their ability to choose how to plan in a specific situation. Reflecting on planning requires specific theories, methods and skills that differ from those that focus on how to plan. In 2006 we developed a new course that provides students more insights into the broad range of knowledge useful for reflection on planning practice..
Planning change: lessons from a Dutch rurban region
Stoep, H. van der; Brink, A. van den - \ 2007

Over the past decades, we increasingly have become aware that many of the changes in metropolitan landscapes have not been the intended result of conscious government action, but more the unintended result of the actions of a variety of actors. This phenomenon has also been described as the gap between planning and implementation. To deal with this problem, the Dutch government has recently directed its focus at process innovation, using the term development planning. It is not clear whether this attempt for process innovation will enable the government to influence spatial change. An exploration of the driving forces of spatial change can inform an answer. We assume that spatial change is determined by interacting multi-level processes. At a regime-level, we find the formal proces of rural-urban planning, which is dictated by existing rules and routines. At the niche-level, actors try to influence landscape development and policy-making, using strategic actions, power resources and coalition building. Finally, at the macro-level, change can be prompted by sudden events or gradual social trends that inspire new policies or political action. We will reflect on the interaction between regimes, niches and the macro-level and its meaning for planning, using an example from planning practice in the Green Hart of the Netherlands. The development of the southern rural-urban fringe of Gouda wil be analysed from a historical and multi-level perspective of planning and change.

The EU is gaining importance in the field of sustainable development. More than 200 directives have been adopted by the European Union in the area of environmental policy as well as hundreds of other measures. Although these directives aim to strengthen each other, there are also practices in which they are conflicting.
Intertwinement of spatial and water policy in European regions: dealing with the risk of flooding
Biesbroek, G.R. ; Knaap, W. van der - \ 2007

The relationship between the European economic regions and the spatial and water policy on EU level remains underexposed, especially given the facing climatic changes. Water issues are not well researched in relation to its effect on spatial planning and vice versa. The European ambition to strive for economical, social and territorial cohesion cannot be seen in European regions even though the ESDP highly values the transnational planning (as both profitable and practical). The polycentric European regions lack administrative structures, policy instruments and resources to implement policy and adequately cope with territorial imbalances and climatic change. With the introduction of the directive on flood management, socio-economical effects of flooding are interlinked with the territorial impacts. The Water Framework Directive uses river basin management plans to cope with water related problems but does not interact with spatial policy and vice versa. A sectoral approach of EU policies creates problems for coherence in a EU territory. Relatively new concepts like territorial cohesion can function as a tool to investigate the intertwinement of spatial and water policy in European regions and at the same time cope with the risk of flooding where integrative policy between spatial and water can result in robust spatial development. During the conference, theoretical assumptions are illustrated with a case study.

Several steps in the scientific development of vegetation research can be distinguish­ed. For a long time, most work emphasized inventory and description, at first merely using qualitative approaches, but later based becoming increasingly quantitative. As time progressed, a better understanding of the ecology and functioning of plant commu­nities became a major topic, reflected in the development of research branches likes eco­hydrology, landscape ecology and experimental ecology. More recently, increasing effort has focussed on the integration of knowledge from different disciplines. This is a demanding and difficult task, for which computer models and so-called information systems prove to be helpful tools. As an example of such a development, the information system SynBioSys Europe, an initiative of the European Vegetation Survey, will be demonstrated. SynBioSys Europe is operational on three levels, that of the plant species, plant community and landscape. On the species level, SynBioSys Europe is developing (in co-operation with the Euro+Med Plantbase project) a synonymised species list for the European vascular and cryptogam flora. At present, the available list of Flora Europaea is incomplete and outdated. Moreover, it is lacking the necessary computerized links with national floras and biological databases. On the vegetation level, SynBioSys Europe uses the newly completed conspectus of European vegetation types. This hierarchic overview comprises 15 formations, 80 vegetation classes, 233 orders and 933 alliances. The classification is based on vegetation descriptions, so-called relevés, of which more than 1.5 million have been made during the last century in Europe.For input, processing and presentation of these phytosociolo­gical data, the software package TURBOVEG (a comprehensive database management system) was designed. Currently, TURBOVEG has been installed in more than 25 countries throughout Europe, resulting in a series of national databases. For the categorisation of landscape types in SynBioSys Europe, the recently published Map of the Natural Vegetation of Europe will be used as a basis. More than 100 geobotanists from 31 European countries cooperated on this map, its legend and the explanatory text. The map has been printed in 9 sheets at a scale of 1:2.5 million. The legend is built-up of different hierarchical levels. It comprises 19 major formations and 700 mapping units. Computerized links between the species checklist, national floras, vegetation tables and landscape types will enable standard query routines to highlight environmental conditions necessary for sustaining plant communities and habitats in Europe
