In Belgium, black alder is well known for its ecological functions, but is generally considered as a secondary species without any true economic value. The present study, based on data pertaining to 166 plots, aims at evaluating the potential of black alder silviculture in the Walloon forest (Southern Belgium). We successively analysed dominant height growth, dominant girth growth and solid stem volume over time. It appears that by controlling competition within stands it should be possible to produce quality, 150-cm girth logs within 50 – 100 years, depending on the level of productivity. The German tables of Mitscherlich (in Schöber, 1975) seem to be most suitable for describing the growth parameters of the Belgian alder stands over time and black alder stand production can be estimated at 3 to 9 m3/ha/year according to site classes. We can conclude that black alder silviculture can be a viable economic activity. [less ▲]

To cope with the economic uncertainties of the changes, transformations, and transitions affecting current European and world agriculture, many farmers are rethinking the purposes of their business and are looking to diversify their activities. Taking advantage of certain assets related to their operation and of opportunities for tourism development in the region (such as availability of buildings, subsidies related to ecology and environment images), some of them have chosen agritourism, a tourist activity proposed by the farmer on his/her farm. The literature includes many studies on this topic, but there is no consensus on terminology, definitions, and concepts: they vary from one author to another and evolve over time. Having distinguished different agritourist typologies in which accommodation is a basic element, we have personally chosen to study agritourism defined as "all tourist and leisure activities and services present in a working farm". Wallonia and the Grand Duchy of Luxembourg, our geographical research areas, are neighbouring entities, with similar agriculture, and their tourist markets offer some similarities. Included in rural tourism, agritourism is nevertheless marginal compared to the overall tourist product offered. Some successes might suggest that agritourism could be the panacea against the crisis in agriculture. But is this always the case? Agritourism should be defined, localized, and differentiated. Working on these two periurban entities of Western Europe which are not yet discussed in the literature, we wanted to understand and to identify agritourist dynamics. We wanted to understand the geographic relationship between agritourism, periurban countryside, local resources, and agricultural and tourist specializations. We wanted to understand the logic of the emergence of tourism on a farm and the links between tourist and agricultural functions in a specific spatial context. Finally, we wanted to understand the integration of the motivations of different types of tourists and their reasons for visiting particular regional and local contexts. To do this, we analyse both the location and the agritourist geographical position in relation to the different markets. To meet the objectives, we conducted a comparative heuristic analysis of agritourism in both territories. We interviewed key organisational representatives (31 persons), we made field observations, documents comparisons... We conducted interviews with various Walloon and Luxembourg farmers (34 life histories) affording different agritourist practices that we synthesized by circumstantial geographical sketches. We conducted surveys with potential tourists (1148surveys) in seven Walloon and Luxembourg tourist spots. These steps and the statistical and cartographic processing based on the results allowed us to build a heuristic geographical model of the Walloon and Luxembourg agritourism. The experiences of farmers interviewed allowed us to understand the position of the agritourist system in its spatial context. Each of them develops opportunities and experience threats (economic, social, from heritage) in connection with the launch of the project, a true survival kit in some cases. It appears that agritourism is not always a panacea for farmers. On the farm, the tourist function comes after the agricultural one and is based on the latter, but the agricultural function also benefits from the tourist function because both activities are related. The emergence of tourism is an autonomous decision of the farmers who can be influenced by other actors, including authorities, but also by other factors such as the existence of a local demand or the regional real estate pressure. There is no particular profile of tourists visiting agritourism, but some features, including those of family, are more favourable to the experience of this type of tourism. Definitions and representations as well as the reasons and expectations differ depending on the characteristics of the interviewed tourists: urban or rural origin, level of experience. Three agritourist profiles were also highlighted: those seeking accommodation in a rural environment, those who think about accommodation linked to gastronomy, those who prefer accommodation that would be a comfortable basis from which to tour in a tourist area. The comparison between the experiences of farmers and the expectations of tourists shows that there is a risk of developing different organizational temporalities in the farm "open" to tourists as well as of favouring unbalanced images of agritourism, which could lead to a vision and a promotion of agriculture which does not correspond to its regional reality. By combining the different results and by linking the typology of the Walloon and Luxembourg agritourist products, the types of rural areas and the geographical components, it appears that agritourism should not only be analysed according to the environmental dimensions, but that the analysis must also take into account other factors such as accessibility, local communities, hospitality, rural development policies, the real estate market, the agricultural orientation of farm operations, as well as the degree of complementarity with tourist spots. We have demonstrated that agritourism, combining agriculture with tourism, is not developing, either everywhere, or in the same manner, and differs between different types of periurban countryside, depending on local resources. Moreover, agritourism is not always a solution for all countrysides, nor always a path for each farmer, nor always a perfect tourist destination for all tourists. However, even if strict regionalization of agritourism does not seem possible when we consider all the factors involved in the different regions, trends may emerge depending on agritourist types. There is thus a link between agritourism type and countryside type, which the heuristic model we propose should allow to improve in order to increase the convergence between the expectations of the different stakeholders.

With the better management of cardiovascular risk factors, cancer plays an increasing role in the causes of death among patients with type 2 diabetes. Numerous epidemiological cohort and case-control studies showed that type 2 diabetes is a risk factor for cancer and that metformin therapy is associated with a significant reduction in the incidence of cancer and cancer-related death when compared to other glucose-lowering agents (sulfonylureas, insulin). Such beneficial effect is observed almost whatever the type of cancer, but seems to be more prominent in case of gastrointestinal and breast cancers. Several studies showed a significant relationship between the amplitude of the protection against cancer, on the one hand, and the daily dose of metformin and the duration of exposure, on the other hand. In general, the protective effect was more evident in observational cohort studies (however, more exposed to bias due to confounding factors) than in case-control studies. Several meta-analyses recently confirmed that metformin therapy reduces the incidence of cancers and cancer-related mortality. However, the results of the rather rare controlled clinical trials available are not conclusive, but none of them was performed with the objective to specifically assess cancer risk. Considering all promising clinical information in patients with type 2 diabetes, further clinical trials are currently ongoing with the aim of assessing the role of metformin in oncology, independently of the presence of diabetes.

L’objectif de cette contribution est de s’interroger sur les potentialités de développement de la filière bois-énergie à l’échelle européenne et de chercher à voir si c’est une réelle alternative aux énergies fossiles. À cette fin, nous avons tenté d’abord de mieux cerner la ressource, puis de mesurer l’importance du bois-énergie et son évolution récente à la fois globalement pour l’UE à 27 et par pays en cherchant à comprendre les disparités entre ces derniers. Enfin, dans une troisième partie, nous répondons aux quatre questions suivantes : quel est le potentiel réellement mobilisable pour ne pas épuiser la ressource ? Quel est son réel bilan environnemental et son impact sur la santé ? Quel est son impact sur l’économie locale d’une région et sur la gestion de la forêt et du territoire proche ? Transformer le bois en agrocarburants, est-ce une fausse bonne idée comment l’a été précédemment le développement des agrocarburants à base de céréales et d’oléagineux ? [less ▲]

Cette enquête est une adaptation d’une étude équivalente réalisée, en 2002, au Québec. Le questionnaire comporte 20 questions réparties en 5 thèmes représentant les étapes de la recherche documentaire. Elle vise à connaître le niveau de compétences documentaires des étudiants qui arrivent dans l’enseignement supérieur, vérifier l’adéquation de celui-ci avec la perception qu’en ont les formateurs et identifier les lacunes afin de permettre d’améliorer les formations. 31 établissements d'enseignement universitaire et non universitaire ont accepté de participer à l’étude. Le questionnaire québécois adapté à la situation belge a été envoyé en septembre 2007 à un échantillon aléatoire de 4388 étudiants accédant pour la première fois à l'enseignement supérieur. Le taux de retour s’élève à 42,57%. Après analyse, il apparaît que comme au Québec, la moyenne des résultats est faible (7,67/20). Outre diverses variables sociologiques, certaines caractéristiques des étudiants sont en lien direct avec le niveau de performance, notamment la fréquentation d'une bibliothèque dans l'enseignement secondaire, le choix d'option dans le secondaire ou le choix actuel d’étude. A contrario, l'utilisation d'Internet ne semble pas favoriser la compétence informationnelle des étudiants. Ces observations confirment la nécessité de proposer des formations aux étudiants pour leur permettre d’atteindre les compétences requises par le métier d’étudiant. Les lacunes observées vont permettre d’adapter les formations existantes. L'étude doit se poursuivre pour évaluer l’impact réel des formations documentaires proposées. [less ▲]
