The Global University Entrepreneurial Spirit Students’ Survey (GUESSS) is an international project that examines students’ entrepreneurial intention and activities in various countries. The Swiss Research Institute of Small Business and Entrepreneurship, at the University of St. Gallen, launched this project in 2003 which is now managed in cooperation with the University of Bern (Switzerland). GUESSS focuses on the current state of student entrepreneurial intention and activities and the antecedents of such phenomena, including entrepreneurial education, supportive environments, and social attitudes. Additionally, the project also examines the process of business creation and dives into some more fine-grained information (e.g., motivations, goals) about students running a business. In 2021, GUESSS partnered with Ernst & Young (EY) and organized its 9th data collection wave, receiving completed responses from 267,366 students across 58 countries. The current report analyzes the data collected by the Belgian national country delegates (i.e., the University of Antwerp, Ghent University, and HEC Management School at the University of Liège). The Belgian dataset comprises answers collected from 2,296 students from large higher educational institutions (HEI) in Flanders and Wallonia. With this report, we hope to provide useful insights into various aspects of students’ entrepreneurial intention and activities in the Belgian context. [less ▲]

Les soins primaires sont soumis à une forte pression par les patients atteints de Covid-19 et ceux touchés par le Long Covid. La question du Long Covid, son diagnostic et son approche thérapeutique sont abordés ici en détail. Le Long Covid est décrit sur base d'un suivi de la littérature mais aussi de l'expérience clinique accumulée en consultation de médecine générale. Les principales caractéristiques de vingt et un cas (seize femmes) de Long Covid rencontrés en 2021 sont exposées. L'expérience de six d'entre eux est relatée sur base des notes de leur dossier médical. Ces six patients ont été interviewés et invités chacun à relire et corriger les textes les concernant. Il s'agit donc d'une étude descriptive basée sur la clinique et la narration du vécu, vérifiée par les patients. Le Long Covid, première maladie dans l'histoire de la médecine à avoir été décrite d'abord par les patients eux-mêmes sur les réseaux sociaux, n'est pas encore précisément définie et les symptômes multi-systémiques peuvent être non spécifiques ou varier en fonction des organes touchés. Le diagnostic repose sur l'écoute attentive de l'histoire du patient. Une fatigue irrépressible inconnue auparavant, un brouillard cérébral, des troubles de la mémoire de travail avec éventuelle anomie, une anosmie, une dysgueusie ou d'autres symptômes multiples survenant après un Covid aigu sont très caractéristiques du Long Covid. Les preuves biologiques du Covid manquent chez dix patients. La PCR a pu être ne pas être faite ou être négative en phase aiguë de la maladie. Les anticorps anti-SARS-CoV-2 ne sont pas toujours présents ou sont indiscernables des anticorps post-vaccinaux. Dans treize des vingt et un cas présentés, la scintigraphie cérébrale (ECD Tc-99m) a pu mettre en évidence un trouble sévère de la perfusion cérébrale. Deux scintigraphies cérébrales de contrôle à trois mois ont montré une amélioration importante. Dans dix cas, les preuves de laboratoire manquent. Le dosage des anticorps tissulaires (Lymphocytes B) est attendu. Un patient qui présente plusieurs mois après un Covid des symptômes médicalement inexpliqués, peut très bien être un Long Covid. Il n'y a aucun traitement spécifique connu. La revalidation neurocognitive et la physiothérapie peuvent aider ces patients qui ont besoin d'un accompagnement empathique à long terme pour supporter leur état [less ▲]

Primary care is under great pressure from patients with Covid-19 and those affected by Long Covid. The issue of Long Covid, its diagnosis and therapeutic approach are discussed here in detail. The Long Covid is described on the basis of a review of the literature and also on the basis of clinical experience in general practice. The main characteristics of twenty one cases (sixteen women) of Long Covid encountered in 2021 are outlined. The experience of six of them is reported on the basis of notes from their medical records. These six patients were interviewed and each was asked to reread and correct the texts concerning them. This is therefore a descriptive study based on clinical and narrative experience, verified by the patients. Long Covid, the first disease in the history of medicine to be described first by patients themselves on social networks, is not yet precisely defined and the multi-systemic symptoms may be non-specific or vary according to the organs affected. Diagnosis is based on careful listening to the patient's history. Previously unknown irrepressible fatigue, brain fog, working memory disorders with possible anomia, anosmia, dysgeusia or other multiple symptoms occurring after an acute Covid are varyingcharacteristics of Long Covid. Biological evidence of Covid is missing in ten patients as PCRs may have been not done or came back negative in the acute phase of the disease. Anti-SARS-CoV-2 antibodies are not always present or are indistinguishable from post-vaccine antibodies. In thirteen of the twenty one cases presented, brain scans (ECD Tc-99m) were able to demonstrate a severe disorder of cerebral perfusion. Two follow-up brain scans at three months showed significant improvement. In ten cases, laboratory evidence was lacking. Tissue antibody testing (B-cells) is expected. A patient who presents several months after a Covid with medically unexplained symptoms may well be a Long Covid. There is no known specific treatment. Neurocognitive revalidation and physiotherapy may help those patients who need long-term empathic support to cope with their condition. [less ▲]

El Covid Largo se describe sobre la base de una revisiónde la literatura, pero también sobre la base de la experiencia clínicaen la práctica general. Se exponen las principales características deveintiún casos (dieciséis mujeres) de Covid Largo encontrados en 2021.La experiencia de seis de ellos se relata a partir de las notas de sushistorias clínicas. Se entrevistó a estos seis pacientes y se les pidió quereleyeran y corrigieran los textos que les afectaban. Se trata, pues, deun estudio descriptivo basado en la experiencia clínica y narrativa,verificada por los pacientes. Long Covid es la primera enfermedad en lahistoria de la medicina que fue descrita por primera vez por los propios pacientes en las redes sociales. Aún no está definida con precisión ylos síntomas multisistémicos pueden ser inespecíficos o variar segúnlos órganos afectados. El diagnóstico se basa en la escucha atenta delhistorial del paciente. La fatiga irreprimible desconocida hasta ahora,la niebla cerebral, los trastornos de la memoria de trabajo con posibleanomia, la anosmia, la disgeusia u otros síntomas múltiples que apa-recen después de Covid agudo son muy característicos de Covid largo.Faltan pruebas biológicas de Covid en diez pacientes. La PCR puede nohaberse realizado o haber sido negativa en la fase aguda de la enferme-dad. Los anticuerpos anti-SARS-CoV-2 no siempre estaban presentes oeran indistinguibles de los anticuerpos post-vacunación. En trece de losveintiún casos presentados, las gammagrafías cerebrales (ECD Tc-99m)pudieron demostrar un trastorno grave de la perfusión cerebral. Dosgammagrafías cerebrales de seguimiento a los tres meses mostraron unamejora significativa. En diez casos, faltaban pruebas de laboratorio. Seespera un ensayo de anticuerpos tisulares (linfocitos B). Un paciente quese presenta varios meses después de un Covid con síntomas inexplicablesdesde el punto de vista médico bien puede ser un Covid largo. No seconoce ningún tratamiento específico.

One objective of the Polstar spectropolarimetry mission is to characterize the degree of nonconservative mass transfer that occurs at various stages of binary evolution, from the initial mass reversal to the late Algol phase. The proposed instrument combines spectroscopic and polarimetric capabilities, where the spectroscopy can resolve Doppler shifts in UV resonance lines with 10 km/s precision, and polarimetry can resolve linear polarization with 1e-3 precision or better. The spectroscopy will identify absorption by mass streams seen in projection against the stellar disk as a function of orbital phase, hot accretion spots, as well as scattering from extended splash structures, circumbinary disks, and other flows in and above/below the orbital plane (e.g. jets) that fail to be transferred conservatively. The polarimetry affects more the light coming from material not seen against the stellar disk, allowing the geometry of the scattering to be tracked, resolving ambiguities left by the spectroscopy and light-curve information. For example, nonconservative mass streams ejected in the polar direction will produce polarization of the opposite sign from conservative transfer accreting in the orbital plane. Also, time domain coverage over a range of phases of the binary orbit are well supported by the Polstar observing strategy. Combining these elements will significantly improve our understanding of the mass transfer process and the amount of mass that can escape from the system, an important channel for changing the final mass, and ultimate supernova, of the large number of massive stars found in binaries at close enough separation to undergo interaction.

The proposed MIDEX mission, Polstar, will provide high resolution UV spectroscopy and spectropolarimetry and offers a unique opportunity to study massive stars in this wavelength range with unprecedented detail. We demonstrate that these observations will provide critical new knowledge of several types of massive stars (specifically the B-emission stars and the Bn stars). We will determine accurate stellar parameters including their rotation rates and variation of surface temperature associated with stellar oblateness. Our work will allow us to detect binary companions and determine binary orbital properties. Binary population synthesis predictions will allow us to determine the fraction of these stars that are spun up due to binary interaction compared to single star evolution. These rapidly rotating stars have the potential to probe mass loss and the mixing of chemical elements which affects their evolution and ultimately the evolution of their surroundings. [less ▲]

Polstar is a proposed NASA MIDEX space telescope that will provide high-resolution, simultaneous full-Stokes spectropolarimetry in the far ultraviolet, together with low-resolution linear polarimetry in the near ultraviolet. In this white paper, we describe the unprecedented capabilities this observatory would offer in order to obtain unique information on the magnetic and plasma properties of the magnetospheres of hot stars. This would enable a test of the fundamental hypothesis that magnetospheres should act to rapidly drain angular momentum, thereby spinning the star down, whilst simultaneously reducing the net mass-loss rate. Both effects are expected to lead to dramatic differences in the evolution of magnetic vs. non-magnetic stars. [less ▲]

The most massive stars are thought to lose a significant fraction of their mass in a steady wind during the main-sequence and blue supergiant phases. This in turn sets the stage for their further evolution and eventual supernova, with consequences for ISM energization and chemical enrichment. Understanding these processes requires accurate observational constraints on the mass-loss rates of the most luminous stars, which can also be used to test theories of stellar wind generation. In the past, mass-loss rates have been characterized via collisional emission processes such as H$\alpha$ and free-free radio emission, but these so-called "density squared" diagnostics require correction in the presence of widespread clumping. Recent observational and theoretical evidence points to the likelihood of a ubiquitously high level of such clumping in hot-star winds, but quantifying its effects requires a deeper understanding of the complex dynamics of radiatively driven winds. Furthermore, large-scale structures arising from surface anisotropies and propagating throughout the wind can further complicate the picture by introducing further density enhancements, affecting mass-loss diagnostics. Time series spectroscopy of UV resonance lines with high resolution and high signal-to-noise are required to better understand this complex dynamics, and help correct "density squared" diagnostics of mass-loss rates. The proposed Polstar mission easily provides the necessary resolution at the sound-speed scale of 20 km s$^{-1}$, on three dozen bright targets with signal-to noise an order of magnitude above that of the celebrated IUE MEGA campaign, via continuous observations that track structures advecting through the wind in real time.

As sources of chemical enrichment, ionizing radiation and energetic feedback, massive stars drive the ecology of their host galaxies despite their relative rarity, additionally to yielding compact remnants, which can generate gravitational waves. The evolution of massive stars is crucially informed by their detailed mass-loss history; however, wind structures on a variety of scales cause important uncertainties on their mass-loss rates. Binary systems can place further constraints on the mass-loss properties of massive stars, especially colliding-wind binaries. In this paper, we review how the proposed MIDEX-scale mission Polstar can critically constrain the physics of colliding winds (and hence radiatively-driven winds in general) with ultraviolet spectropolarimetric observations, providing an unprecedented improvement on the accuracy of the determination of both mass-loss rates and the velocity structure of the winds of massive stars. We propose a sample of 17 targets that will allow us to study a variety of wind-colliding systems spanning a large parameter space using the spatial information yielded by both spectroscopic and polarimetric data obtained with Polstar.

Structural robustness and mitigation of progressive collapse is a specific safety consideration which is now addressed in modern codes and standards, including the Eurocodes, and which requires particular care from all professionals involved in the construction industry, including architects, designers, constructors, control officers, and insurance managers. The importance of the robustness design has been recognised by world shacking disasters such as the 9/11 collapse of Twin Towers in New York City and the need for practical guidelines has been triggered. Indeed, the availability of such guidelines for practical application addressed to various construction professionals considering different use and risk of buildings helps to ensure confidence in safety of steel and composite construction. During the past decade, a significant number of research projects related to the structural response of steel and composite buildings under various exceptional loading situations (impact, fire, earthquake,…) have been carried out, especially in Europe and in the USA. As an outcome of these recent scientific actions, different possible practical methods have been proposed to achieve the mitigation of progressive collapse through effective designs and accounting for the full potential of material characteristics in steel and composite structures. Purpose of the project “Mitigation of the risk of progressive collapse in steel and composite building frames”- FAILNOMORE, is to consolidate the knowledge developed in the aforementioned research and transform it into practical recommendations and guidelines. The set of practical and user-friendly design guidelines for mitigating the risk of progressive collapse is focused on steel and composite structures subjected to exceptional events such as impact, explosions, fire, seismic, referring also to available normative documents, in order to propose a commonly agreed European design methodology. The project was funded for 24 months (starting from July 2020) by the Research Fund for Coal and Steel (RFCS) under grant agreement No 899371.The present design manual is a part of dissemination material and reflects the main outcomes of the FAILNOMORE project. The present document is divided into three parts: • Part 1 entitled “Design for robustness” which reflects the design strategies and the design approaches to be adopted. In particular, the normative context is first presented in Section 1.Then, in Section 2, the design methodology to be followed and the design strategies which can be adopted are briefly introduced. Finally, detailed and practice-oriented design guidelines on how to apply the different proposed design approaches are provided from Section 3 to 6 with general conclusions drawn in Section 7. • Part 2 entitled “Worked examples” which illustrates how the different design approaches can be applied on four actual design examples: a steel and a composite structure designed in a non-seismic area and a steel and a composite structure designed in a seismic area. • Part 3 entitled “Annexes” which provides the reader with additional detailed information regarding some of the proposed design concepts. • Part 4 entitled “References” which collects the references mentioned in the present document.

The SCOPE study assesses the prevalence of anti-SARS-CoV-2 antibodies among a representative sample of residents and staff in Belgian NH (nursing homes). Starting from February 1st 2021, a cohort of 1,640 residents and 1.368 staff members in 69 Belgian NHs are being tested every two months on the presence of anti-SARS-CoV-2 antibodies. This brief communication reports on the prevalence of anti-SARS-CoV-2 antibodies among vaccinated nursing home residents and staff. At the end of April 2021, the large scale vaccination campaign in Belgian nursing homes, which took place between January 5th and March 24th 2021, resulted in a vaccination coverage of 97% in NH residents and 84% in staff members. For these vaccinated groups, we describe the prevalence of anti-SARS-CoV-2 antibodies immediately following the vaccination campaign (April, 2021) and the seroprevalence evolution over the two following testing periods (in June and August 2021). Data collection of the August 2021 testing period was not finished at the time of compiling this brief communication. The August 2021 testing period comprises the data from 65 out of the 69 nursing homes. Additionally, some antibody test results are expected the coming weeks in case of self-sampling (for staff in particular). Results given here are preliminary. Small adaptations in some data might occur in future reports. [less ▲]

Ultimate Beneficial Owners (UBOs) are defined by complex legal rules that differ across countries. Identifying UBOs is increasingly costly and time consuming. Gathering more data and refining already complex domestic legal arsenals is not the solution. We therefore propose a risk-based approach to identifying possible UBOs, which is enabled by recent theoretical advances in economics and corporate finance. The proposed methodology is robust, rigorous and cheap to implement. In the same way that a risk-based approach has facilitated the adoption of transparency standards for banks (Basel), this methodology could constitute the basis for the gradual adoption of an international standard.

Faisant partie intégrante de l’économie sociale, l’entrepreneuriat coopératif suscite depuis une bonne dizaine d’années déjà un réel regain d’intérêt. En effet, de par ses valeurs et ses pratiques de gestion spécifiques, tant les citoyens que les entrepreneurs sociaux voient le modèle coopératif comme une opportunité concrète de répondre à leurs préoccupations sociétales actuelles. Année après année, en Wallonie notamment, nous observons une augmentation significative du nombre d’entreprises et d’emplois créés dans le secteur coopératif, ce qui permet d’apporter une réponse territorialisée à certains objectifs de développement durable inscrits à l’agenda politique wallon4. Fin 2014, en réponse à cette dynamique entrepreneuriale et citoyenne (ré-)émergente, le Gouvernement régional a chargé W.Alter de mettre en place un dispositif de soutien public—essentiellement financier—à la création et au développement des coopératives wallonnes. Dès 2015, ce dispositif « brasero »5 a permis de doubler—sous certaines conditions—les ressources financières investies par les acteurs privés dans les fonds propres de ces coopératives. Suite au succès rencontré par Brasero, le Gouvernement a décidé à plusieurs reprises de revoir à la hausse les modalités et moyens financiers mobilisés. Au terme de 2020, le dispositif aura permis de soutenir un total de 89 coopératives pour un montant global engagé dépassant les 10 millions d’euros. L’heure est aujourd’hui au bilan. Souhaitant devenir pionnière en matière d’entrepreneuriat social et coopératif, la Wallonie s’est récemment dotée d’une stratégie de développement de l’économie sociale (Alternativ’ES Wallonia) pour les quatre prochaines années, en accord avec sa Déclaration de politique régionale (DPR) 2019-2024. La présente mission (MARCHE N°O6.03.03-21-0572) s’inscrit dans l’application de cette stratégie et vise à étudier, auprès d’une diversité d’acteurs, les effets générés par 6 ans d’opérationnalisation du dispositif Brasero. En s’appuyant sur une approche évaluative à la fois quantitative (phase 1) et qualitative (phase 2), cette étude devra outiller W.Alter en matière d’évaluation de ce dispositif. Elle devra aussi permettre de formuler des pistes d’amélioration en lien avec les besoins des porteurs de projets, de W.Alter ou encore de l’écosystème d’Economie Sociale en Wallonie (phase 3). Plus globalement, cette mission vise à objectiver les raisons d’être d’une politique transversale de soutien à l’économie sociale wallonne, ici en l’occurrence coopérative, en combinant deux approches : - Une approche rétrospective, établie sur base de l’étude du processus et des effets générés par les 6 premières années d’opérationnalisation du dispositif Brasero (2015-2020) ; - Une approche prospective, (1) en fournissant un outil de monitoring6 pour continuer à évaluer le dispositif, (2) ainsi qu’en formulant des propositions d’aménagement des modalités stratégiques et opérationnelles qui tiennent compte des réalités de terrain et des besoins spécifiques de l’ensemble des parties prenantes concernées, à savoir les porteurs de projets financés et finançables, les financeurs privés d’entreprises, W.Alter ou encore la Région wallonne.

La Directive-cadre sur l’eau (DCE, 2000) et sa traduction dans la loi française (LEMA, 2006) définissent le contexte en matière de politique de l'eau. Elles impliquent une gestion globale et intégrée des milieux et écosystèmes aquatiques pour atteindre un « bon état écologique ». Cet objectif est défini sur la base de la situation des communautés biologiques et des caractéristiques physico-chimiques de l'eau mais pas uniquement. Les conditions hydrologiques et la morphologie des cours d'eau sont considérées comme les facteurs de contrôle, ou « supports », de la biodiversité aquatique au travers des habitats qu’elles contribuent à mettre en place.

S’intéressant tant à la forme des lits fluviaux, qu’aux sédiments qu’ils transportent, à la structure ou composition des berges ou encore à la qualité des corridors rivulaires végétalisés, l’ensemble est ainsi représenté par 3 grands éléments de qualité DCE (EQ) multi-compartiments (i-e Hydrologie, Continuité de la rivière, Morphologie).Dans ce rapport, il est tout d’abord proposé d’établir un état des lieux des données disponibles à l’issue des 4 mises à jour et des optimisations réalisées depuis le début de l’année 2019 au sein de l’Interface d’Exploitation des Données Carhyce (IED). Est présentée ensuite la nouvelle version du référentiel d’analyse dit « Référentiel v2.0 » basée sur les relevés récents d’une large majorité des stations de référence (au sens du fonctionnement hydromorphologique). Est proposée également une clé d’interprétation de l’Indicateur morphologique global (IMG) grâce à une comparaison avec le Morphological quality index (MQI), un indicateur morphologique utilisé en Italie. Enfin, cette étude conclut sur quelques éléments de réflexions sur les potentialités et perspectives du Lidar pour la caractérisation hydromorphologique des cours d’eau. [less ▲]

Due to global warming, more and more people are attracted by freshness of water in swimming pools but also in many other locations, including cities fountains, pounds… If the natural bathing area is located downstream of a wastewater treatment plant, a tertiary treatment of water is needed before disposal in rivers to respect the European Directive 2006/7/CE for surface water bathing area in term of microbiological water quality. According to this directive, intestinal Enterococcus must stay under 330 CFU/100 ml and Escherichia coli can’t overpass 900 CFU/100 ml in natural bathing waters. Currently, the most conventional and useful technology to reduce pathogens uses UVC lamps, no matter if they are low or medium pressure. The UV energy alters the DNA structure of the microorganism in a process called thymine dimerization. Despite the excellent results achieved by most of the UVC reactors, there are some technical and economic constraints: • To avoid inadequate disinfection during the heating phase, the UVC lamps must run continuously, which leads to high energy costs and a reduction in lifetime. • High operating costs of UVC devices due to the energy needs and to the price of UVC lamps (replacement every 12 months or after 12000 operating hours). • Frequent oversizing of the UVC dose due to quartz sleeves fouling, and/or scaling, the water transmittance and the suspended solid load. • Potential reactivation of microorganisms after UVC under visible light and/or in darkness. Recently, photocatalysis and photo-induced processes have proved being effective for disinfection based on their deactivation capacity on numerous bacterial strains (John J. Alvear-Daza, & Al., Solar Energy 171, pp 761–768, 2018). The aim of the project is to validate at pilot scale the effective and definitive disinfection performance of sol-gel photocatalytic reactor combined with UVA illumination as tertiary treatment of a waste water treatment plant or in closed circulating loops, taking advantage of killing germs by affecting their cell wall instead of DNA alterations.

Sexual violence (SV) is a major public health, judicial and societal concern in Belgium. A comparative and representative study of SV in Belgium is still lacking. SV may induce long lasting sexual, reproductive, physical and mental ill-health affecting the victim and his/her peers, offspring and community. People exposed to violence during childhood are susceptible to subsequent (re)victimization, perpetration and maladaptive parental practices, which contributes to the intergenerational transmission of violence. The complex mechanisms behind coping behaviours as well as the effectiveness of response measures to all genders has not been studied. At political level in Belgium, the current national action plan on violence advocates a holistic management of SV victims. Furthermore, a new Ministerial Guideline on the Sexual Aggression Set (SAS) has just been issued while Sexual Assault Care Centres (SACC) are being piloted. The recent transfer of competences to the regions reorganises the judicial landscape. Hence the necessity to conduct a Belgian representative prevalence SV study examining all vulnerabilities to victimisation and perpetration. [less ▲]

From February 1st until March 24th, 2021, the SCOPE study measured the proportion of residents and staff members in Belgian nursing homes (NH) that had anti-SARS-CoV-2 antibodies (seroprevalence). In total, 1,572 residents and 1,253 staff members from 69 NHs in Belgium were tested for the presence of SARS-CoV-2 antibodies by a point-of-care rapid test, and responded to a COVID-19 related questionnaire. At the first testing moment (five bimonthly follow-up testing moments are scheduled), we observed the following:Between February 1st and March 24th, 2021, during the ongoing SARS-CoV-2 vaccination campaign, 69% (95% CI: 63%-74%) of residents and 80% (95% CI: 76%- 83%) of staff in Belgian nursing homes had anti-SARS-CoV-2 antibodies. At the time of testing 96% of the residents received at least one vaccination dose and 68% were fully vaccinated. For staff this data were respectively 85% and 48%. So, although more residents than staff were vaccinated at the moment of testing, seroprevalence was lower among residents than among staff. At least one day after receiving one dose of a COVID-19 vaccination, 52% of residents tested positive for anti-SARS-CoV-2 antibodies and 77% tested positive at least one day after receiving two doses. Among staff these findings were higher, being respectively 75% and 98%. The proportion of residents and staff with antibodies after vaccination was higher among those who reported a previous SARS-CoV-2 infection than among those without a self- reported previous infection.

This study aims to delineate the supervisory role of the EDPS with respect to the European Public Prosecutor's Office (EPPO) and to analyse some practical consequences of the different possible approaches. While the EPPO is a body of the European Union (EU), it is unique in its hybrid structure as it consists of a central office, located in Luxembourg, and decentralized offices at Member State level. Its operational functioning will involve actors at both levels. At decentralized level, the European Delegated Prosecutors play a pivotal role: while they act on behalf of, and clearly belong to the EPPO, they are also part of the national public prosecutor’s office and endowed with the same powers as national prosecutors. Inherent to the functioning of the EPPO is its cooperation with national authorities on which the EDPs will rely heavily to conduct and/or authorize investigation measures. While the exchange of information with EU authorities is largely regulated by the Regulation establishing the European Public Prosecutor's Office, the cooperation with national authorities is mainly left to national law. Considering the involvement of multiple actors in future EPPO investigations, the processing of data will inevitably take place at different levels, raising key questions regarding the applicable data protection regime and the competence of supervisory authorities. These questions, most of which have not yet received much attention (in legal literature and elsewhere), will prove to be essential for the smooth functioning and supervision of the EPPO’s operational activities in terms of data protection. In particular, this study will focus on the following questions: - What is the scope of application of the data protection regime laid down in the EPPO Regulation? How does this regime relate to the rules defined by Regulation (EU) 2018/1725, Directive (EU) 2016/680 (LED) and the national laws? The latter obviously includes legislation that implements the LED, but also other legislation having a direct impact on data protection in the context of criminal investigations. (Part III) - What are the EPPO’s powers and tasks regarding the processing of personal data? (Part IV) - What is the theoretical interplay between the data protection rules of the EPPO Regulation and national legislation? In this respect, the study will primarily examine the following three areas: 1. Data subjects’ rights (including limitations and restriction of these rights); 2. the processing of special categories of operational personal data; 3. transfers of operational personal data. (Part V) - What is the concrete interplay between the data protection rules of the EPPO Regulation and national legislation? What is the responsibility of the EPPO and Member State authorities respectively with regard to the processing of personal data in the context of the EPPO’s activities? Which law applies to this processing? (Part VI) - Finally, what are the repercussions of the above on the EDPS’s supervisory role with respect to the EPPO and to what extent is coordination with national supervisory authorities required? (Part VII) Before addressing these questions, the study will briefly highlight some distinctive features of the EPPO that are relevant for the subsequent analysis (Part II). [less ▲]

Ce travail termine une recherche menée depuis 2017 sur les relations entre les malades chroniques, les aidants proches et les soignants dans le cadre du projet RéLIAN mené à Liège. Tout d’abord, une étude qualitative a interrogé des triades composées de ces différents acteurs : un patient, son aidant.e, un de ses soignants. Entre autres choses, la reconnaissance insuffisante de la place des aidants proches par les professionnels de santé y été pointée. Ensuite, en 2018, des groupes nominaux ont été organisés auprès d’aidants proches, et de médecins généralistes et spécialistes, afin de préciser les attentes des uns et des autres. Ce rapport décrit la ronde Delphi menée au départ des résultats de l’étape précédente. Trente-trois propositions ont été proposées et discutées au cours de trois rondes, entre octobre 2019 et septembre 2020. Elles ont rassemblé 22 participants : des parties prenantes du côté des professionnels (associations scientifiques, syndicales, académiques), des représentants des associations d’aidants et de patients, et des acteurs du monde politique. Le consensus obtenu porte sur 4 aspects : • L’identification des aidants, où l’on distingue une identification fonctionnelle utiles aux parties en présence, et une identification formelle pouvant donner l’accès aux avantages accordés par la loi. • Le soutien à accorder aux aidants par les médecins : écoute et information sur la maladie et ses implications, sur les services d’aide structurés ; attention à la souffrance des aidants. • L’accès aux données de santé de la personne malade, conditionnée à la pertinence des données pour les actions de l’aidant, à l’autorisation de la personne aidée, et à l’identification de l’aidant auprès de la mutuelle. • La place des aidants dans le réseau de soins et les modalités de collaboration taillées sur mesure pour chaque situation. D’une façon générale, les médecins étaient d’accord sur la philosophie globale de laisser de la place et de l’attention aux aidants. Par contre, dès que cet aspect devait être formalisé et contractualisé, on percevait plus de réticences. La définition de l’aidant semble se faire à travers le prisme d’une relation individualisée du soin (un malade, ses symptômes et la réponse médicale), et ne devient plus collective et rapportée au milieu de vie qu’à partir de la chronicisation d’une situation. Le consensus élaboré par des parties prenantes – si bien choisies eussent-elles été – ne garantit pas automatiquement la transférabilité des résultats sur le terrain. [less ▲]

The present deliverable reflects the outcome of the activities conducted in the framework of Task 2.1 of WP 2 of the FAILNOMORE project. The objective of this specific task was to derive practice-oriented design approaches from the information collected in Deliverable 1-2, i.e. the background document. Within the present document, these practice-oriented design approaches are reported in two parts: - Part 1 (from Section 1 to Section 4) entitled “Find my way” which groups the design recommendations to help the designer in the identification of the approaches to be considered in the context of a design for robustness and; - Part 2 (Sections 5 and 6) entitled “Tool box” which provides the designer with the required information to apply the different design approaches addressed in Part 1. In the next step of the FAILNOMORE project, the applicability of the proposed design approaches will be illustrated through the worked examples (Task 2-2). Then, the dissemination materials made of a design manual (including the design recommendations and the worked examples) and of PowerPoint presentations will be prepared (Task 2-3) taking into account of the outcomes from Tasks 2.1 and 2.2.

This research project, funded by ONE Academy and part of an interdisciplinary project with Uliege (Pr. Pirard) and UMons (Pr. Gaugue), addresses the issue of gender in childhood professions and in parenthood and education of young children. The Liege compenent of this research project is particularly interested in the relationship between parents and professionals, specifically in the place given to fathers in the early childcare services and in meeting places for parents and children (play groups). Indeed, the scientific literature and experiences show some difficulties in the relationships between parents and professionals, especially with fathers. Far from any fatalism, the proposed device aims to identifying levers validated by field experiments. It is based on a collaborative approach between researchers, experts from different disciplines and actors in the field of early childhood. As for the Montois component, it questions the experience and adaptation of young fathers in immediate and late postpartum, by attempting to highlight resources and vulnerabilities during this period. A complementary look is taken at the father-baby bond through the observation of dyads met at home. [less ▲]

Lake Edward is one of the East African Rift lakes (surface 2325 km2, maximum depth 112 m), is located on the border between the Democratic Republic of Congo (DRC) and Uganda. It is connected to the smaller lake George (surface 250 km2, maximum depth 3m) through Kazinga Channel, and is part of the Nile watershed. On both sides of the border, Lake Edward is bordered by two major natural reserves, the Virunga National Park, Queen Elisabeth National Park. A collapse of the fisheries of Lake Edward was observed from the 1960’s to 1980’s that matched the reduction of the numbers of hippos observed from the 1960s and 1970s. The reason of this collapse is unknown, nor if fisheries continued to decline until present. The aim of HIPE was to test the causal relationship between the recent environmental changes and the drastic reduction of fisheries productivity. Our working hypothesis was that several environmental pressures in the watershed of Lake Edward have disrupted the biogeochemical, structural and functional links between the terrestrial and aquatic ecosystems, leading to a collapse of the main ecosystem service provided by Lake Edward. The fishing effort has dramatically increased since the 1960s. This in combination with a relaxed enforcement, resulted in an overexploitation of the fish stock and a spread of the use of damaging fishing techniques around the lake. Other potential causes are changes in the hydrological cycle, which could have also modified the transfer of nutrients from the watershed to the lake, and climate variability affecting nutrient cycling and availability in the Great Lakes. Shallow sediment cores from Lake Edward show a shift in stable carbon isotope composition in the upper 10 cm of the core (approximately last 40 yrs) that could be explained by (i) an increase in the delivery of C3-derived organic matter to the lake, and/or (ii) a decrease in phytoplankton productivity, which would increase isotope fractionation in phytoplankton due to alleviation of diffusive CO2 limitation. Museum-archived fish specimens confirm a shift in the baseline δ13C values in the lake, corresponding to a lower productivity or a change in the composition of terrestrial organic matter input to L. Edward over the past century. A range of bivalve shells analyzed for C and O isotope ratios along their growth lines indicate these are excellent tools to differentiate habitats, but this compromises their use as archives for paleo-environmental reconstruction in the area since exact provenance of museum collection specimens is typically not sufficiently well documented. The data from tooth enamel from Hippopotamus canines show a long-term trend towards decreasing δ13C values of the Hippopotamus diet in the region, although showing a high inter-individual variability in δ13C values, most pronounced in more recent specimens, indicating that dietary differences exist on small spatial scales. As Hippopotamus are thought to be rather indiscriminate grazers, this should reflect local differences in relative C3-C4 cover. The oxygen stable isotope data of Hippopotamus were shown to be likely good proxies for their lacustrine versus riverine habitat use. The phytoplankton community in Lake Edward was largely dominated cyanobacteria (60% of the phytoplankton biomass), followed by diatoms (25% of the phytoplankton biomass), and by green algae, chrysophytes and cryptophytes. 248 taxa phytoplankton were identified with clear prevalence of cyanobacteria (104 taxa), from the morphological groups of coccal and filamentous species (non-heterocytous and heterocytous). Compared to historical data from the 1930’s it seems a shift in algal diversity (number of species) from diatoms to cyanobacteria. Lack of historical data does not allow to determine if a change in total phytoplankton biomass occurred. The primary production measured in Lake Edward during the three cruises was approximately 4 times lower than the single historical value (June 1960), but values seemed comparable in Lake George compared to those from the 1960’s. This is consistent with an overall decrease of present phosphorus loading compared to historical data (1990’s). Primary production rates were high, and in excess of community respiration, indicating a net autotrophic status leading to low values of dissolved CO2. Consequently, Lake George and the part of Lake Edward influenced by the outflow from Lake George acted as sinks for atmospheric CO2. This challenges the paradigm that inland waters are systematically sources of atmospheric CO2 that was derived from data mostly collected in boreal and temperate lakes. The sampled sites were in some cases very strong CH4 emitters to the atmosphere, although a very strong spatial variability was observed due to a combination of several factors such as the occurrence of anoxia in bottom waters and productivity, both related to depth (the shallowest systems being the most productive and devoid of bottom anoxia). Most systems were sinks of atmospheric N2O due to denitrification. Data on stable C, N and H isotope composition indicate that aquatic primary production is the dominant energy source at the basis of the foodweb, but the wide variability in consumer stable isotope signatures also indicates that a wider variety of sources is used, with contributions of terrestrial and possibly CH4-derived carbon. The basin of Lake Edward has a fish fauna that is typical for East Africa and consists of two components: a species-rich assemblage of Haplochromis species and a relatively species-poor assemblage of non-Haplochromis species. A total of 34 non-Haplochromis species belonging to 10 families and 21 genera are recorded from the system. These include six species of major importance to the fisheries. Three non-Haplochromis species are endemic to the system and two others have been introduced in the region. Six species are new records for the Lake Edward system. The Haplochromis species diversity was seriously underreported and went from 27 species known to 56, of which 13 new ones have been or are being described. We have currently no indication that species have disappeared from the system in the last few decades, though one catfish species known from historical records, H. longifillis, could not be retrieved during the recent expeditions. Substantial dietary niche overlaps were found between several commercially important fish species, while niche overlaps between Haplochromis species were small, which suggests that they display a high trophic differentiation in accordance with their specialised morphologies. We did not find indications that different stocks exist for the commercial species. However, we found that the populations in the lakes were separated from those inhabiting the rivers. We did find intraspecific differences in morphology and ecology between populations from Lake Edward and Lake George (including the Kazinga Channel) of some Haplochromis species. No signs of large-scale hybridization were found between the two important tilapias. Recent reports on the state of the fisheries of the Lake Edward system remain scarce. Lakes Edward and George are almost completely within protected areas. However, occupied land area, the number of inhabitants and the number of boats has risen substantially during the last decades. Total annual yields have been increasing in the last ten years, but Catch Per Unit Effort (CPUE) appears to be continuously decreasing. Tilapias, which were traditionally dominant in the catches, seem to have crashed in the eighties and their share in the catches keeps decreasing. Recent estimates showed poor stock status for most commercially important species with most stocks defined as either collapsed, recruitment impaired or overfished. Higher catches could be obtained under sustainable management. The immediate target of management should be rebuilding biomass to the biomass at maximum sustainable yield (Bmsy). A survey was conducted at the different landing sites along lakes Edward and George. This revealed that fishers were aware of the changes in the state of the fishery. Fishers attributed declining catches to excessive effort, fishing malpractices, destruction of breeding grounds, and pollution. Communities reported large-scale non-compliance with fisheries regulation, especially at Lake George. [less ▲]

This case study addresses the impact of BIM technologies on work organization, labor force and working conditions as well as on social dialogue and industrial relations. By focusing on the “tram of Liège project” – conducted a consortium of two companies: COLAS and CAF – we would like to show how the BIM technologies were used in the project and changed several work habits. BIM is often restrictively seen as a modelling tool, which functionalities are limited to designing through 3D models. The purpose of this study is to show that BIM’s impacts on work are cross-cutting. One of our objectives is to show that BIM’ effects are not limited to the Colas group but also concern its partners and clients, as it changes the interactions between stakeholders. Although BIM affects many aspects of work, we will show that the technology is poorly known and receives little attention from trade unions. [less ▲]

Ce modèle propose un processus par étapes permettant une conduite plus méthodique, plus fluide et plus structurée des projets Smart City. Pour rappel, notre Guide Pratique de la Smart City – Tome 1 suggérait un parcours de réflexion en plusieurs phases favorisant une transition globale au niveau d’un territoire. L’objectif du présent modèle est de poursuivre cette réflexion pour l’appliquer à l’échelle de projets spécifiques. Le présent document constitue un mode d’emploi à l’adresse de toute personne désireuse de mener un projet Smart City. Ce document doit être considéré comme un guide permettant d’appréhender et de contrôler chaque étape d’un projet. Celui-ci est accompagné d’un modèle (SPMM) à compléter par la personne en charge du projet, seule ou de façon collaborative. Concrètement, ce modèle permet dans un premier temps d’avancer plusieurs idées autour du projet mais aussi d’adapter ces dernières en fonction des évolutions du projet. Il comprend des cases à compléter notamment à l’aide de post-its et des cases à cocher afin de marquer la validation de certaines étapes. Enfin, il peut être considéré comme un véritable outil de réflexion, de communication et de suivi. [less ▲]

Entre 2010 et 2017, le nombre d’élèves primo-arrivants inscrits dans un DASPA (Dispositif d’Accueil et de Scolarisation des élèves Primo-Arrivants) a doublé en Fédération Wallonie-Bruxelles (FWB). La majorité de ces élèves sont allophones et doivent donc rapidement apprendre le français pour suivre avec succès les activités scolaires et s’adapter aux enseignements en français dans les différentes disciplines scolaires. Or, on sait que la maitrise de la langue d’enseignement, loin de se réduire à la seule maitrise du code linguistique, constitue une problématique importante pour les élèves, qu’ils soient francophones ou allophones. Les élèves doivent en effet s’approprier des pratiques langagières diversifiées : le français langue de communication scolaire, mais aussi les usages de l’écrit (compétences littéraciques) et des genres de discours spécifiques aux disciplines, liés à des activités cognitives (observer, décrire, expliquer,…) et à des concepts. La maitrise de ce « français langue de scolarisation » concerne donc aussi bien l’enseignement des disciplines en français, que l’enseignement du français comme discipline (langue première ou seconde). Cependant, l’articulation entre la mise à niveau linguistique des élèves allophones primo-arrivants et le développement des compétences langagières liées aux matières scolaires reste actuellement problématique. Les enseignants manquent d’outils et de méthodes appropriés, notamment pour le positionnement initial et l’évaluation, qui leur permettraient de faire face à la complexité des trajectoires des élèves, à leur plurilinguisme et à la transition délicate entre le dispositif d’accueil et la classe ordinaire. À partir d’un état des lieux critiques des dispositifs existants, et des données recueillies auprès de directeurs·trices d’écoles secondaire de la FWB, d’enseignant·es, de conseiller·es pédagogiques et de membres des services d’inspection, nous avons, d’une part, contribué à l’élaboration d’outils d’évaluation de la maitrise la langue de l’enseignement (fondamental et secondaire), et, d’autre part, créé un module d’autoformation (en ligne) en didactique du français langue de scolarisation, destiné aux enseignant·es qui accueillent des élèves allophones dans leur classe. Le présent rapport fait état des résultats de la recherche menée dans 5 écoles secondaires qui organisent un DASPA en Wallonie et à Bruxelles, ainsi que du module de formation des enseignants (SPOC ULiège) que nous avons conçu.

Cette étude porte sur les pratiques transitionnelles mises en place lors de l’entrée d’un enfant à l’école maternelle.Ces pratiques ont pour objectif d’assurer la continuité éducative entre les différents milieux de vie de l’enfant (Ruel, 2011) par une double action : le soutien à l’enfant dans l’acquisition de ressources qui lui sont nécessaires et, l’organisation pour les parents d’occasions de rencontre et de communication avec les professionnel-le-s (Dunlop, 2017). Cette recherche s’appuie sur les résultats de la recherche "Les pratiques de transition lors de l'entrée à l'école maternelle : état des lieux". Elle propose des analyses de cas à visée compréhensive dans quatre établissements. L’analyse porte spécifiquement sur les pratiques effectivement mises en œuvre ainsi que le sens et les significations qui leur sont données par les acteurs concernés (professionnel·le·s, parents, indirectement enfants). Les résultats donnent des perspectives intéressantes et permettent de mieux appréhender la complexité de la problématique. [less ▲]

Depuis quelques mois, les différents gouvernements, en Belgique ou ailleurs, ont dû prendre des mesures afin de lutter contre la crise sanitaire provoquée par la Covid-19. Ces mesures ont impacté le mode de fonctionnement des villes et communes qui ont dû s’adapter. Au Smart City Institute, en cette période complexe, la combinaison des concepts de « territoires durables et intelligents » et de « crise » nous a conduits à mener une recherche empirique en Wallonie afin de mieux appréhender les impacts de la crise de la Covid -19 sur la transition durable et intelligente de nos territoires (« Smart Cities/Territories » en anglais). De multiples questions se posent et notamment, cette crise va-t-elle ralentir ou, au contraire, accélérer cette transition ? Ce rapport est l’occasion d’évoquer des premières pistes de réponse. Bien que nous ne puissions pas encore déterminer la totalité des effets à long terme de cette situation, cette recherche permet de dresser un premier état des lieux. Nos résultats indiquent que durant cette période complexe, les communes wallonnes ont vu en cette crise une opportunité de générer un changement positif, notamment au travers de la transition numérique. Le nouveau contexte induit par la crise sanitaire a créé, sous certains aspects, un terrain favorable au développement de territoires intelligents à travers la Wallonie. De nouvelles solutions numériques qui n’étaient pas envisagées auparavant font désormais partie intégrante de la nouvelle façon de travailler dans les administrations publiques locales. S’il est encore trop tôt pour affirmer qu’elle a effectivement accéléré la transition durable et intelligente du territoire wallon, la crise aura toutefois ouvert de nouvelles perspectives à nos villes et communes.

Ce rapport de recherche sur l’investissement des espaces extérieurs (IEE) par les enfants de 18 mois à 18 ans, financé par l’Office de la Naissance et de l’Enfance (2018-2019), est le fruit d’une collaboration entre des chercheurs de différentes disciplines représentées au sein de l’Unité de Recherche « Enfances » (sciences de la motricité, anthropologie et sciences de l’éducation) de l'Université de Liège et du Réseau des Initiatives Enfants-Parents-Professionnel·le·s (RIEPP). Objet de préoccupation relativement récent en Fédération Wallonie-Bruxelles, l’IEE est abondamment traité dans la littérature qui montre entre autres une diminution du temps passé à l’extérieur dans les pays dits développés (en raison de la densification de la circulation routière, du surinvestissement des écrans, ou encore de l’évolution sécuritaire de notre société) alors qu’il présente de nombreux avantages et bénéfices individuels et collectifs. L’IEE contribue en effet grandement au développement global des enfants, et particulièrement à leur santé physique, motrice et psychologique, comme à leur socialisation, à l’éveil de leurs sens, au développement de leur autonomie ainsi qu’à l’apprentissage d’une gestion mesurée des risques. Plus globalement, la question de l’IEE est en lien avec des préoccupations actuelles majeures qui vont de la santé publique à la lutte contre les inégalités en passant par les défis environnementaux. Réalisée à partir de deux enquêtes quantitatives, d'études de cas sociologiques et de monographies anthropologiques, cette recherche étudie les représentations (bénéfices, freins, dangers, leviers), les discours et les pratiques relatifs à l’IEE, tant des adultes encadrants (parents, professionnel·le·s de l’accueil de l’enfance) que des enfants eux-mêmes. Elle propose une problématisation de la thématique en dépassant la notion d’espace extérieur pour prendre en compte l'ensemble des environnements dans lesquels les enfants évoluent et comprendre les tensions, les contradictions et les contraintes qui sous-tendent l’IEE. La recherche débouche sur vingt-deux recommandations qui montrent l’importance d’encourager l’IEE en reconnaissant le rôle fondamental que peuvent jouer conjointement les enfants et les adultes (parents et professionnel·le·s) dans le développement des actions et projets présents et futurs.

Depuis les années septante, le rôle des forêts a évolué d’une fonction principalement économique et productrice de bois vers une multifonctionnalité qui tient également compte des aspects écologiques, récréatifs, éducationnels et sociétaux. L’évolution des besoins de chacun et la prise en compte des services écosystémiques que les forêts peuvent nous fournir sont ainsi mis en avant. Parallèlement, le caractère non renouvelable des sols a été mis en évidence et des politiques ont été développées afin de préserver leur qualité. Une gestion forestière plus ‘durable’ se développe en tenant compte des différentes fonctions de la forêt, ainsi que de l’influence des pressions anthropiques (exploitation, changements climatiques, pollution). La diversification des essences est apparue comme une option de gestion possible, afin de maintenir les services écosystémiques fournis par les forêts, d’augmenter la résistance et résilience aux stress. Pour mesurer l’impact de cette diversification, une bonne connaissance du fonctionnement de l’écosystème est indispensable. D’où le besoin d’outils de suivi et de diagnostic. L’objectif général des recherches est d’étudier l’équilibre nutritionnel à long terme de deux bassins versants de ca. 80 ha, en mesurant les concentrations et les flux en éléments minéraux entrants (pluies, pluviolessivats) et sortants (solution du sol, exutoire), ainsi que d’évaluer la variabilité spatiale et temporelle de la qualité biologique des sols au sein de ces deux bassins versants. Les recherches concernent particulièrement l’effet des essences et des mesures de gestion sylvicole sur les activités microbiennes des sols et la biogéochimie de l’écosystème forestier. Les concentrations et flux en éléments minéraux et en carbone organique dans les pluies, pluviolessivats, la solution du sol sont mesurés dans 15 placettes d’études intensives et à l’exutoire de deux bassins versants (La Robinette et Waroneu). En plus, la biomasse des arbres est mesurée bisannuellement et les sols sont analysés annuellement. Ce rapport résulte d’une subvention entre le SPW et l’ULiège d’une durée de 12 mois. Dans ce rapport nous présentons l’historique des mesures, la gestion de la base de données avec l’intégration des données avant et après 2014, les résultats de l’échantillonnage des sols de novembre 2019 pour les indicateurs biologiques , les mesures de biomasses des placettes du bassin versant de Waroneu, et des propositions d’installations et d’analyses complémentaires à mettre en place dans le cadre de la directive NEC. Résultats • Mesures à long terme des concentrations et flux en éléments minéraux et en carbone organique dans deux bassins versants forestiers et évolution à long terme des dépôts acides et azotés : Des graphiques montrant les concentrations pour les éléments majeurs dans les pluviolessivats des différentes placettes des deux bassins versants entre janvier 2013 et janvier 2018 ont été présentés. • Mesures des indicateurs biologiques de la qualité des sols forestiers (échantillonnage de novembre 2019) : les analyses des indicateurs biologiques de la qualité des sols ont été poursuivies en 2019. Nous constatons que la coupe des épicéas scolytés de la placette W05 de Waroneu a eu un impact négatif sur la biomasse microbienne (quantité des microorganismes), la minéralisation nette (activité des microorganismes) et le quotient microbien (qualité du substrat). • Biomasse des arbres dans les placettes intensives de Waroneu : lors de l’inventaire 18 des 29 épicéas repris sur la placettes W05 de Waroneu avaient été abattus en urgence pour cause de dégâts dû aux scolytes. • Gestion de la base de données : une méthodologie semi-automatique assurant une sauvegarde et un contrôle des données a été implémentée. Les données d’avant 2014 et celles entre 2014 et 2018 ont été agrégées en une seule base de donnée. La vérification de cette base de données est en cours, et des graphiques des concentrations, des calculs des budgets et les analyses statistiques pour les bassins versants intégrant les nouvelles placettes vont pouvoir être réalisés. La base de donnée ainsi pérennisée pourra être plus aisément exploitée, y compris par des tiers. • Historique des récoltes : un article scientifique de forme ‘data paper’ est en cours de finalisation. Il reprendra l’historique de toutes les expériences, systèmes de récoltes et collecteurs installés dans les deux bassins versants de La Robinette et de Waroneu depuis le milieu des années 1980 jusqu’à maintenant, ainsi qu’une description détaillée de la base de données. • Rapportage pour la directive NEC : le rapportage a été effectué comme prévu pour juillet 2019, nous attendons le retours d’information à son sujet. Nous avons réalisé un inventaire des données supplémentaires et des méthodes qu’il faudrait éventuellement implémenter ou modifier. Une complémentarité entre les demandes pour la directive NEC et le réseau eLTER existe entre autre pour des mesures de type météorologique et des mesures complémentaires lors des échantillonnages des sols. Il nous parait important de pérenniser les bassins versants en tant qu’outils de mesures uniques au sein de la Wallonie et donc de veiller à nous adapter pour maintenir le plus haut standard possible pour la collecte et l’intégration de nos données.
