The present deliverable aims at providing any CoP member, CoP animator or CoP mediator with the most complete view of the PALETTE tools and services. It gives a voice to the developer, the educationalist, the ergonomist and of course the user to explain how they consider them. So, it suggests use cases, scenarios but also shows to the reader where are the obstacles of use (with the aim of avoiding a too quick discouragement on his/her part) and it provides real users’ testimonies. It illustrates the participative design, core of the project, by showing how various kinds of partners in the project work at their evolvement. Several times, it evokes how they interact in that way. More, for the sake of completeness, external services which are "social network" oriented, are described in terms of functionalities and with the concern of providing the audience with a largest view of how ICT may help CoPs to grow up.

Harbour porpoises (Phocoena phocoena) and harbour seals (Phoca vitulina) are far more abundant along our coast compared to the beginning of the nineties. Human impact on these species is however hard to establish, mainly due to lack of information on marine mammal population ecology, density, distribution and diversity. This project aims to gain further knowledge on the viability of the harbour porpoise and harbour seal populations in the North Sea (focusing mainly on its southern Bight) through - The characterisation of their genetic structure and diversity (through mtDNA and microsatellites in harbour porpoises) - A better understanding of their feeding ecology (through δ13C and δ15N measurements in muscles) - The assessment of their susceptibility of being trapped accidentally in fishing nets (post-mortem investigations) Harbour porpoise and harbour seal occupied the top trophic levels but displayed different feeding habits as inferred from their δ13C and δ15N mean values. Harbour porpoises displayed lower mean δ15N values suggesting a lower trophic position likely oriented towards small planktivorous fish such as herring and lesser sandeel. However, both their recent high abundance and their dietary preferences might lead to a higher susceptibility to by-catch as revealed by the significant emergence of net entrapment and net marks revealed by post-mortem investigations. The question rises about the sustainability of these incidental captures. Furthermore, genetic investigations revealed a higher fragmentation of the porpoises collected along the coast of France, Belgium and Netherlands. This apparent fragmentation is of particular importance from a conservation point of view and enhances the fact to protect in priority these last populations. Our study showed importance of multidisciplinary approaches (post-mortem investigations, stable isotope measurements (δ13C and δ15N measurements) and genetic investigations using mtDNA and microsatellites) to apprehend the question of marine mammal survival in our waters.

In this paper we use annual data on 92 French electricity distribution units (2003-2005) to estimate a benchmarking model that includes a quality of service indicator (number of interruptions). Our methodology involves the estimation of input distance functions using stochastic frontier analysis (SFA) and data envelopment analysis (DEA) techniques. The empirical results indicate that the inclusion of the quality variable has no significant effect upon mean technical efficiency scores, and the mean shadow price of one interruption is approximately ten Euros. The analysis in this paper is the first preliminary step in a larger project which is investigating the feasibility of including quality measures into benchmarking models that are often used by regulatory authorities [less ▲]

The purpose of this study is to provide information that can help the Commission and EU Member States engage in policy discussion on how social, health and long-term care systems can help enhance participation in work and family, social and community activities and how, in turn, participation in paid employment, family, social and community activities can contribute to healthy and autonomous living at present and in the future. Part I presents a review of the literature on the synergy between health and activity/work. Health affects work and social participation but on the other side work and activity affect health. We focus on people aged 55 and over as this interrelation (double causality) seems to be significant for important life events (retirement decision, social participation, etc.) of this age group. Part II presents a quantitative analysis and tries to identify national specificities. It presents the lessons which we can draw from European surveys. It presents a quantitative analysis based on the LFS, the EU-SILC, the ECHP UDB and SHARE surveys. The fourth step summarises national policies and gives a comparative analysis, while the fifth step presents the best practices. Finally, the last part summarises the main conclusions and the policy implications. [less ▲]

La mission du CREPP était de présenter une synthèse des travaux portant sur la mesure du travail au noir en général et en Belgique en particulier.

Dans le texte ci-dessous on trouvera la synthèse des études existantes qui conclut que la plupart des estimations macroéconomiques sont discutables, voire fan¬taisistes. Notre conviction est que l’approche macroéconomique est stérile. L’approche correcte est sectorielle et elle devrait s’appuyer sur deux types de données: les données administratives et les données d’enquêtes portant sur tous les acteurs: offreurs, demandeurs et autorités de contrôle.

Les résultats obtenus dans le cadre du suivi DCE 2006 du phytoplancton des eaux côtières corses ont permis: − de tester et de valider une stratégie d’échantillonnage originale adaptée aux réseaux de surveillance et aux spécificités régionales; − de caractériser globalement les communautés phytoplanctoniques de 6 masses d’eau côtières ne présentant pas de risque NABE à l’horizon 2015 (Calvi, Cargèse, Pianottoli, Est Cap Corse, Sud Bastia et Sant’Amanza); - de démontrer le très bon état des masses d’eaux échantillonnées pour l’indicateur Phytoplancton; - d’émettre des recommandations visant à optimiser l’effort d’échantillonnage et la validité des résultats. La stratégie d’échantillonnage testée et validée propose de réaliser deux suivis « haute fréquence » au niveau des sites de référence de Calvi et de la station « Sud Bastia ». L’échantillonnage doit être réalisé en subsurface toute l’année, une fois par semaine de janvier à juin et une fois par quinzaine de juillet à décembre. Les autres masses d’eau sont échantillonnées une fois par mois, de janvier à décembre. Les résultats 2006 mettent en évidence les caractéristiques communes des communautés phytoplanctoniques des masses d’eau de Calvi, Cargèse et Pianottoli et des masses d’eau Est Cap Corse, Sud Bastia et Sant’Amanza. Ceci suggère que les suivis réalisés dans le cadre des contrôles de surveillance pourraient se limiter aux observations « haute fréquence » réalisées à Calvi et à la station « Sud Bastia ». [less ▲]

A new three-dimensional Earth system model of intermediate complexity was developed. This model, named LOVECLIM, consists of five major components representing the atmosphere (ECBilt), the ocean and sea ice (CLIO), the terrestrial biosphere (VECODE), the oceanic carbon cycle (LOCH) and the Greenland and Antarctic ice sheets (AGISM). It also includes a global glacier-melt algorithm which is run in off-line mode. It is worth mentioning that there are very few models of this type worldwide. ECBilt is a quasi-geostrophic atmospheric model with 3 levels and a T21 horizontal resolution. It includes simple parameterisations of the diabatic heating processes and an explicit representation of the hydrological cycle. Cloud cover is prescribed according to present-day climatology. CLIO is a primitive-equation, free-surface ocean general circulation model coupled to a thermodynamic–dynamic sea-ice model. Its horizontal resolution is 3° × 3°, and there are 20 levels in the ocean. VECODE is a reduced-form model of vegetation dynamics and of the terrestrial carbon cycle. It simulates the dynamics of two main terrestrial plant functional types (trees and grassland) at the same resolution as that of ECBilt. LOCH is a comprehensive model of the oceanic carbon cycle that takes into account both the solubility and biological pumps. The version utilised here has the same resolution as the one of CLIO, which greatly facilitates the coupling between both models. Finally, AGISM is composed of a three-dimensional thermomechanical model of the ice sheet flow, a visco-elastic bedrock model and a model of the mass balance at the ice–atmosphere and ice–ocean interfaces. The Antarctic ice-sheet module also contains a model of the ice-shelf dynamics to enable interactions with the ocean and migration of the grounding line. For both ice sheets, calculations are made on a 10 km × 10 km resolution grid with 31 sigma levels. The performance of LOVECLIM was assessed by conducting ensemble simulations over the last few centuries. Starting from different initial conditions, the model was integrated from year 1500 AD up to year 2000 AD with solar irradiance, volcanic activity, tropospheric ozone amount, greenhouse-gas (including CO2) concentrations and sulphate-aerosol load evolving with time according to reconstructions. Over the last 140 years, the model simulates a global surface warming ranging from 0.33°C to 0.43°C, with a mean value of 0.38°C. This value is about 0.15°C lower than the observed one. A detailed analysis of the results has revealed the model behaves reasonably well at mid- and high latitudes. By contrast, at low latitudes, the agreement between the model results and observational estimates is less good, especially in the Southern Hemisphere. In those regions, LOVECLIM significantly underestimates the warming and the climate variability observed during the last few decades. The coarse resolution of the model and the simplified representation of the atmospheric dynamical and physical processes seem to be the two major candidates responsible for this deficiency. Regarding the Greenland ice sheet, we found a slightly increasing ice volume during the period 1700–2000 AD. This trend is largely explained as a residual response to the late Holocene forcing, in particular to the Little Ice Age cooling after year 1500 AD. The effect is not particularly large, however, amounting to only 1.2 cm of global sea-level rise over the entire period. The growing trend stabilizes during the 20th century, with almost no net effect on ice volume. Only during the last decades of the 20th century, the ice volume begins to decrease in response to the imposed warming. We also found the Antarctic ice sheet to be retreating slowly at a rate equivalent to a global sea-level rise of about 1.7 cm during the 20th century. This evolution is mostly due to a long-term background trend of +2.6 cm, mitigated by about 0.9 cm from slightly rising accumulation rates over the same period. The ongoing dominance of past climatic changes on the contemporary ice-sheet evolution is a fine illustration of the inertia encountered when studying the response of large continental ice sheets. In this case, it mainly results from an ongoing grounding-line retreat in West Antarctica following rising sea levels since the Last Glacial Maximum. As far as mountain glaciers and small ice caps are concerned, their area and volume are found to reach a maximum in the late 19th century corresponding to the Little Ice Age, but this maximum and the ensuing 20th century glacier retreat are not very pronounced. Over the last hundred years, the model simulates an ice loss equivalent to only 0.89 cm of sea-level rise. This value is at the lower end compared to other assessments. One reason is the low total ice volume assumed by the global glacier-melt algorithm (about 20 cm of total sea-level rise, a factor 2.5 less than previous estimates). A second reason is the prescribed global ice mass balance for the 1961–1990 reference period, which is also at the lower end of other simulations. For the 20th century, LOVECLIM explains about 7.6 cm of sea-level rise. The bulk of that value, about 4.7 cm, comes from thermal expansion of the World Ocean. The Antarctic and Greenland ice sheets combined lead to a sea-level rise of 2 cm, and glaciers and ice caps are responsible for about 0.9 cm of sea-level rise. These numbers are similar to those that have been derived for the IPCC Third Assessment Report (TAR) for the same components except for the lower glacier contribution as found here. Over the industrial era, the net uptake of carbon by the ocean simulated by LOVECLIM is within the range of current estimates, although at the lower end of this range. It should be noted that a detailed evaluation of the performance of the terrestrial carbon-cycle module was impossible to perform given the very wide range of available data. Experiments with interactive atmospheric CO2 concentration were also carried out with LOVECLIM forced by CO2 emissions from fossil fuel burning and land-use change. Interestingly enough, the atmospheric CO2 level computed by the model in year 2000 AD compares relatively well with the observed one. A series of climate-change projections were then conducted over the 21st century. In these experiments, LOVECLIM was driven by changes in greenhouse-gas (including CO2), tropospheric ozone and sulphate-aerosol concentrations following the IPCC SRES scenarios B1, A1B and A2. In year 2100 AD, the model predicts a globally averaged, annual mean surface warming of 1°C, 1.4°C and 1.8°C for scenarios B1, A1B and A2, respectively, and an associated increase in precipitation of 3.6%, 5.1% and 6.6%, respectively. In agreement with studies performed with climate general circulation models (CGCMs), a weakening of the Atlantic meridional overturning circulation (MOC) is noticed in all runs. At the end of the 21st century, the decrease in the maximum value of the annual mean meridional overturning streamfunction below the surface layer in the Atlantic basin, which is an index of the MOC intensity, reaches 19% for scenario B1, 21% for scenario A1B and 27% for scenario A2. In our model, as in the majority of CGCMs, this decrease is caused more by changes in surface heat flux than by changes in surface freshwater flux. Under the forcing scenario A1B, LOVECLIM simulates a global sea-level rise of 31.3 cm in year 2100 AD. As for the 20th century, the most important contributor is the oceanic thermal expansion (+18.8 cm), followed by the contributions from the Greenland ice sheet (+5.2 cm), glaciers and ice caps (+3.8 cm) and the Antarctic ice sheet (+3.5 cm). The total rise is equivalent to a quadrupling of the sea-level rise simulated for the 20th century. Our sea-level value is somewhat lower than the central estimate for the same four components of about 40 cm in the IPCC TAR predictions. This can be explained by the low climate sensitivity of LOVECLIM, and hence the lower global temperature rise, which mostly affects the largest contribution of thermal expansion of the World Ocean. Another difference with the IPCC TAR predictions is the positive contribution from Antarctica of several cm of sea-level rise. That is in contrast to most other simulations showing a growing ice sheet and a negative contribution to global sea level of typically between -5 and -20 cm. The IPCC TAR also found a generally larger contribution from mountain glaciers and small ice caps. Our glacier-volume loss is smaller because of the lower initial glacier volume assumed by the glacier-melt algorithm. The total projected sea-level rise for the 21st century is only slightly affected by the scenario itself. For the range of SRES scenarios used by LOVECLIM, the total sea-level rise is found to vary between +22 and +35 cm by year 2100 AD. The much larger range of between +9 and +88 cm obtained for the IPCC TAR arose mainly from the inclusion of model uncertainties, and not from the greenhouse-gas-forcing scenarios employed. As expected, climate change impacts the air–sea CO2 exchange in the model by lowering the solubility and hence the net uptake of carbon by the ocean. The effect is however rather modest at the century time-scale given the moderate increase in sea-surface temperature simulated by LOVECLIM. In addition, we do not observe any significant change in the oceanic biology at the global scale during the 21st century. The picture is a bit different regarding the terrestrial biosphere. Both the climate and fertilization effects strongly increase the carbon uptake in VECODE. A number of experiments with interactive atmospheric CO2 concentration were also carried out over the 21st century. Contrary to other modelling studies, LOVECLIM predicts lower atmospheric CO2 levels at the end of the 21st century when the effect of climate change on the carbon cycle is accounted for in the model. The warming enhances the net uptake of carbon by the terrestrial biosphere which more than offsets the reduction in oceanic uptake resulting from the solubility decrease. Finally, we have thoroughly analysed the model response to a range of stabilized anthropogenic forcings over the next millennia. For the variety of forcing scenarios considered, LOVECLIM simulates a globally averaged, annual mean surface warming ranging between 0.55°C and 3.75°C and an associated decrease in Arctic and Antarctic sea-ice extent. However, no simulation predicts an entirely ice-free Arctic Ocean during summertime at the millennium time-scale. In the most pessimistic case, a small ice pack of about 0.5×106 km2 persists. Our results also suggest that it is very likely that the volume of the Greenland ice sheet will largely decrease in the future. After 1000 years of model integration, the ice volume is reduced by more than 20% when the radiative forcing is higher than 6.5 W m-2. Moreover, for a radiative forcing greater than 7.5 W m-2, the ice sheet melts away in less than 3000 years. Note that the ice-sheet disintegration might be even more rapid if processes responsible for the widespread glacier acceleration currently observed in Greenland were taken into consideration in the model. We also found that the freshwater flux from the melting Greenland ice sheet into the neighbouring oceans, which peaks in the most extreme scenario tested at 0.11 Sv (1 Sv = 10^6 m3 s-1) and remains above 0.1 Sv during three centuries, is not large enough to trigger a shutdown of the Atlantic MOC in our model, in contrast to some other models. Those models are however more responsive to freshwater perturbations than ours. Besides, we showed that climate feedbacks play a crucial role in the ice-sheet evolution and that the Greenland deglaciation considerably enhances the greenhouse-gas-induced warming over Greenland and the central Arctic. This stresses the importance of incorporating the two-way interactions between the Greenland ice sheet and climate in climate- and sea-level-change projections at the millennial time-scale. For the Antarctic ice sheet, the response is much less drastic than for the Greenland ice sheet. For instance, after 3000 years of 4×CO2 forcing (∼7.7 W m-2), the Antarctic grounded ice volume and area are reduced in our model by only 8% and 4%, respectively. For a sustained radiative forcing of 8.5 W m-2 (the highest forcing scenario considered in our study), LOVECLIM predicts a global sea-level rise of 7.15 m by year 3000 AD. Most of it is due to melting of the Greenland ice sheet (+4.25 m), followed by melting of the Antarctic ice sheet (+1.42 m), thermal expansion (+1.29 m) and the contribution from mountain glaciers and small ice caps (+0.19 m). Our results show that it will be very difficult to limit the eventual sea-level rise to less than 1 m after 1000 years, unless the atmospheric CO2 concentration can be stabilized to less than twice its pre-industrial level. Such a goal can only be reached by emission reductions far larger than any policy currently pursued. Concerning the carbon cycle, the experiments carried out with LOVECLIM highlight the opposite responses of the terrestrial and oceanic carbon reservoirs to climate change. We also found that, when anthropogenic CO2 emissions cease, the terrestrial biosphere becomes a weak carbon source, while the ocean continues to be a sink. It should be mentioned that no dramatic change in the global marine productivity is observed in our simulations. This arises from the fact that the modifications of the oceanic properties that affect this productivity (stratification, meridional overturning, …) are rather moderate. The effects of climate change are however not negligible. In particular, the decrease in sea-ice extent predicted by the model results in a longer growing season and a larger nutrient uptake (especially silica) in polar regions. As a result, by the end of the 23rd century, silica concentrations in the upper 100 m of the Southern Ocean drop by as much of 30% for the most extreme forcing scenarios. [less ▲]

A sustainable agricultural production chain (“from stable to table”) is not produced ex nihilo, especially when its future hinges on demand from a supermarket distribution circuit. Many of the standards of conventional production chains effectively serve as references for intermediaries and consumers alike. The tensions between sustainability standards and market standards are thus the crucial areas in which negotiations about the chain’s future take place. These inextricably intertwined technical, social, and economic tensions are the subject of this research. These tensions create a situation of uncertainty, that is to say, of choices between pathways. They are both a springboard for action and the cause of inaction, depending on how they are interpreted.

This deliverable summarises all the hydrogeological experiments performed in the scope of the AquaTerra project by HGULg in the Flémalle test site. These experiments consisted in various hydraulic tests and tracer tests performed to quantify hydrodynamic and hydrodispersive properties of the alluvial gravel aquifer and to evaluate groundwater fluxes in the aquifer and at the aquifer-river interface. First steps in groundwater modelling are also presented. [less ▲]

The study is conducted in the frame of a programme of monitoring of all landfill sites in Wallonia. The "odour" part is assigned to ULg. The present report concerns more particularly a second campaign on the site of Hallembaye. The research group applied the usual field inspection technique to assess the global odour emission rate generated by the site. The influence of relief is particularly discussed with the results of 3D modelling. [less ▲]

Tracer experiments were performed in the Brévilles test site in order to highlight vertical variations in groundwater fluxes related to vertical variations hydraulic conductivity, to estimate contaminant travel time from several locations in the catchment to the springs and to identify transport processes affecting the fate of solutes in the saturated part of the aquifer. Following a first tracer experiment with uranine and sulforhodamine G in 2003, four tracer injections were performed in November 2005 in different piezometers, using uranine, sulforhodamine B, iodide and lithium. Tracer concentrations were monitored in the injection wells and at the basin outlet (spring and gauging station). Using the FVPDM method, concentration evolutions monitored in the injection wells allowed one to estimate local Darcy fluxes. At the basin outlet, only two tracers were recovered. Analyses of breakthrough curves confirm the stratification of the aquifer with more permeable levels in the lower part. They also suggest the probable occurrence of vertical interactions within the aquifer. [less ▲]

A sustainable agricultural production chain (“from stable to table”) is not produced ex nihilo, especially when its future hinges on demand from a supermarket distribution circuit. Many of the standards of conventional production chains effectively serve as references for intermediaries and consumers alike. The tensions between sustainability standards and market standards are thus the crucial areas in which negotiations about the chain’s future take place. These inextricably intertwined technical, social, and economic tensions are the subject of this research. These tensions create a situation of uncertainty, that is to say, of choices between pathways. They are both a springboard for action and the cause of inaction, depending on how they are interpreted. This exploration is what justified an intervention-research approach that combines restating questions and changing relations to explore the possible pathways to take. [less ▲]

La Région wallonne ne dispose actuellement d’aucune réglementation spécifique aux nuisances olfactives, ni en ce qui concerne les propositions de mesures d’odeurs, ni en matière de valeurs limite à respecter. L’application d’une réglementation ou la préparation de textes nouveaux, se traduit par la nécessité de disposer de méthodes et de moyens de mesures adéquats : ceux-ci sont décrits dans les normes, qu’elles soient allemandes (VDI), françaises (AFNOR), européennes (CEN) ou internationales (ISO). L’objectif principal de cette étude est de tester et d’améliorer la procédure de décision en matière de nuisances olfactives, devant permettre de baliser l’instruction des dossiers d’octroi de permis en fonction de critères propres à l’installation et à son environnement. L’outil qui servira à remplir cet objectif est un arbre de décision dichotomique. Les objectifs secondaires qui en ont découlé sont :  une première « carte d’identité odeur » par secteur d’activité ;  des recommandations en matière d’interprétation des données de mesure dans un objectif de réglementation. Ce rapport débute avec un état de l’art en matière de législation, dans lequel nous abordons la tendance actuelle et la critique des législations nationales ainsi qu’un résumé de la législation de la Région flamande. Le chapitre trois présente les différentes techniques de mesures de l’odeur. Les méthodes peuvent être soit sensorielles, soit physico-chimiques ou soit électroniques. On retrouve par exemple dans les premières : le facteur d’émission, l’olfactométrie dynamique au seuil de perception, le traçage d’odeur sur le terrain, l’évaluation des percentiles, la grille de mesure, le journal tenu par les riverains et l’intensimétrie. L’évaluation systématique de la qualité des méthodes de mesure en termes de précision ou de reproductibilité ne sont pas reprises dans ce rapport, en effet celle -ci peut être trouvée dans la littérature. La méthodologie suivie pour arriver à répondre à l’objectif principal se base sur les trois points suivants : une trentaine de visites d’exploitations industrielles, une discussion avec divers spécialistes et une revue de la bibliographie. Cette méthodologie nous a permis de créer une démarche scindée en une première partie de récolte de données, suivie d’une seconde partie analytique. Dans cette dernière, nous présentons tout d’abord les outils qui permettent d’évaluer l’impact olfactif sur la population et ensuite l’arbre de décision qui a pour fonction de déterminer la méthode de mesure la plus appropriée.

This deliverable presents the participatory design methodology of the PALETTE project and some first results of the implementation of this process. Some principles of the Actor Network Theory and of the Agile Methodology are embedded in the different stages of this methodology whose twelve stages (described in details in the last section) will be the basis of the participative development of services and scenarios of use. The first two stages of the process, establishing the collaboration with the CoPs and modelling their activities, have been implemented. Concrete results are available, i.e. procedures implemented to enrol the partners, methodological tools to gather and analyse the data from the CoPs. Some information has been communicated to partners of WPs 2, 3, 4 and 5 that needed it to progress in the development of their work. This process is not ended; it is iterative and will be refined all along the project. [less ▲]
