Towards the redefinition of the meaning of the Meuse Valley landscape in Liège: proposal for a landscape experiment

The localization of the city of Liège, in the Meuse (Maas) valley, later the development of its industries and its port, were all conditioned by the natural geography of its site. Yet today the site itself and its natural characteristics are seldom perceptible from within the city. The large scale destructions in the city fabric during the last two centuries broke up its historical siteresponsive urban morphology. The disappearing industry left the landscape scarred with now meaningless traces, and no strong alternative vision for its future. While the region is waiting for “the” solution, for the definitive project that will give it new impulse and identity, the abandoned industrial sites and many of their surroundings are turning into “non-sites”. To gain a new vision specific to the valley, one must read todays’ landscape as a palimpsest left by rural uses and urban developments, including industrial artifacts, overlaid on its original geomorphology. A “project” approach, such as that proposed by many landscape architects at different scales, from garden to forest and larger urban development, offers a way of observing and interpreting the landscape, eventually leading to iterative, local interventions, (“landscape acupuncture”). Inspired by the site-responsive agricultural past of the valley, the interventions should lead to a new spatial language of urban agriculture and forestry. Each of these interventions can turn into a “landscape laboratory”, involving local stakeholders, whose aim is to articulate small scale landscape elements with long-term place and time-contextual investment, and thus redefine its identity.Peer Reviewe

La promenade comme acte esthétique

La promenade – l’une des multiples manières de marcher – est une attitude de marche particulière, où le promeneur se rend disponible aux sollicitations des qualités spatiales polysensorielles des lieux qu’il traverse. Mêlant perception et imagination, la promenade est un « acte de construction de sens », requérant la « compétence de situation » du promeneur.“Taking a walk” (se promener), as opposed to other ways of -and motivations for -walking, implies an acute, multi-sensory receptivity to places crossed. Combining perception and imagination, the taking of a walk is synonymous with the “construction of meaning” and requires a “situational competence” on the part of the walker

Multiobjective and social cost-benefit optimisation for a sustainable hydrogen supply chain

This article presents a comprehensive approach to design hydrogen supply chains (HSCs) targeting industrial and mobility markets. Even if the inclusion of sustainability criteria is paramount, only a few studies simultaneously consider economic, environmental, and social aspects - the most difficult to measure. In this paper, the safety risk and the social cost-benefit (SCB) have been identified as quantifiable social criteria that would affect society and the end-users. The objectives of this research are (1) to design a sustainable HSC by using four objective functions, i.e., levelized cost of hydrogen, global warming potential, safety risk and social cost-benefit through a mixed-integer linear programming model; (2) to compare results from SCB and multiobjective optimisation. The integration of the SCB criterion at the optimisation stage is not a trivial task and is one of the main contributions of this work. It implies the minimisation of the total cost of ownership (TCO) for buses and trucks. The evolution of the HSC from 2030 to 2050 is studied through a multiobjective and multiperiod optimisation framework using the ε-constraint method. The methodology has been applied to a case study for Hungary with several scenarios to test the sensitivity of demand type and volume as well as the production technology. The results analysis highlights that (1) it is beneficial to have mixed demand (industry and mobility) and a gradual introduction/migration to electrolysis technology and fuel cell vehicles (FCVs) for a smooth transition. Liquid hydrogen produced via water electrolysis powered by nuclear and wind energy can result in an average levelized cost of $4.78 and 3.14 kg CO2-eq per kg H2; (2) the frameworks for multiobjective optimisation and SCB maximisation are complementary because they prioritise different aspects to design the HSC. Taxes and surcharges for H2 fuel will impact its final price at the refuelling station resulting in a higher TCO for FCVs compared to diesel buses and trucks in 2030 but the TCO becomes almost competitive for hydrogen trucks from 2035 when SCB is maximised. The SCB function can be refined and easily adapted to include additional externalities

Identifying social aspects related to the hydrogen economy: Review, synthesis, and research perspectives

Energy transition will reshape the power sector, and hydrogen is a key energy carrier that could contribute to energy security. The inclusion of sustainability criteria is crucial for the adequate design/deployment of resilient hydrogen networks. While cost and environmental metrics are commonly included in hydrogen models, social aspects are rarely considered. This paper aims to identify the social criteria related to the hydrogen economy by using a systematic hybrid literature review. The main contribution is the identification of twelve social aspects which are described, ranked, and discussed. “Accessibility”, “Information”, “H2 markets”, and “Acceptability” are now emerging as the main themes of hydrogen-related social research. Identified gaps are e.g., lack of the definition of the value of H2 for society, insufficient research for “socio-political” aspects (e.g., geopolitics, wellbeing), scarce application of social lifecycle assessment, and the low amount of works with a focus on social practices and cultural issues

Trajectoires doctorales

Presque deux décennies après la première mise en place des diplômes d’études approfondies au sein de quelques écoles nationales supérieures d’architecture françaises, les rencontres doctorales organisées à Nantes en septembre 2010 ont mis en avant une jeune communauté de chercheurs structurée à l’échelle nationale. Premières d’une longue série, elles illustrent la capacité des disciplines de la transformation de l’espace à l’acclimatation au monde réel : d’une part, notamment dans le contexte des problématiques environnementales ; d’autre part, à l’égard des exigences relatives à l’évaluation scientifique. Il n’y a là rien d’étonnant, alors qu’à l’échelle internationale cette filière de recherche et d’enseignement a su trouver une place méritée au sein des universités. Peut-on par conséquent considérer les « objets de recherche comme attracteurs ? », s’interroge Laurent Devisme en introduction, évoquant la force de certaines thématiques en ce qu’elles peuvent transgresser les limites disciplinaires pour rejoindre des préoccupations dominantes de la société. Yannis Tsiomis dans son post-scriptum souligne à son tour que « toutes ces recherches nous parlent aussi, et pour certaines de manière critique, des visions du monde, des visions politiques, au sens générique du terme ». Phrase emblématique d’une trajectoire personnelle qui a su donner forme et contenu au « triangle vertueux » profession / enseignement / recherche. Trajectoires doctorales dessine dans ce numéro les contours d’un paysage de la recherche architecturale, urbaine et paysagère en pleine transformation, par des documents de docteurs et de doctorants explorant avec rigueur et inventivité de nouveaux horizons

Universal Dependencies Treebanks 1.2 (see http://universaldependencies.org/)

Universal Dependencies is a project that seeks to develop cross-linguistically consistent treebank annotation for many languages, with the goal of facilitating multilingual parser development, cross-lingual learning, and parsing research from a language typology perspective. The annotation scheme is based on (universal) Stanford dependencies (de Marneffe et al., 2006, 2008, 2014), Google universal part-of-speech tags (Petrov et al., 2012), and the Interset interlingua for morphosyntactic tagsets (Zeman, 2008)
