Rewilding Urban Space. The Regeneration of Budolfi Plads (Aalborg, DK)
2022
Tackling environmental degradation and halting the growing loss of biodiversity are among the most urgent imperatives at the turn of the third millennium. In response to the global environmental crisis, different approaches to nature conservation, biodiversity protection and ecosystem restoration are emerging.
Les comportements de protection face au risque naturel : de la résistance à l’engagement
2011
An adequate risk management requires taking into account all the categories of stakeholders, including the exposed populations. Nowadays, one difficulty is to involve these populations and consequently to understand their reactions face to the eventuality of a disaster's occurrence. Several issues must be addressed: how is the representation of risk built up ? How do people develop adaptive strategies towards risk ? And above all, how is it possible to ensure an increase in behaviours suited for prevention and protection ? After drawing up a report on the research in this area, we will discuss the limitations of a persuasive communication, in order to better understand the interest of a bin…

Scale-dependent patterns and drivers of vascular plant, bryophyte and lichen diversity in dry grasslands of the Swiss inneralpine valleys
2022
AbstractThe inner-alpine dry valleys of the Swiss Alps are characterized by subcontinental climate, leading to many peculiarities in dry grassland species composition. Despite their well-known uniqueness, comprehensive studies on biodiversity patterns of the dry grasslands in these valleys were still missing. To close this gap, we sampled 161 10-m2 vegetation plots in the Rhône, Rhine and Inn valleys, recording vascular plants, terricolous bryophyte and lichen species, as well as environmental data. Additionally, we tested the scale-dependence of environmental drivers using 34 nested-plot series with seven grain sizes (0.0001–100 m2). We analysed the effects of environmental drivers related…
Metamorfosi della materia ed essenza del metallico. La teoria schellinghiana dei metalli nobili dall’Esposizione del mio sistema filosofico (1801) al…
2014
The aim of the present contribution is to explore Schelling’s theory of noble metals within the texts he wrote between 1801 and 1804, especially the System of Würzburg (1804). Schelling’s theory of noble metals and the closely related theory of the relationship between cohesion and specific gravity undergo a change between 1801 and 1804. In the Exposition of my Philosophical System (1801) Schelling places emphasis on the conflict between gravity and cohesion, and he conceives the relationship between specific gravity and cohesion in terms of inverse proportionality. Consequently, in this work he pays very little attention to the noble metals. In the texts that follow (1802-03), however, he …
Importance des récentes variations pluviométriques à Djibouti et besoins de quantification de leurs impacts
2014
Ces dernières décennies, l’Afrique de l’Est souffre d’une longue et lente détérioration pluviométrique. De 2007 à 2011, la ville de Djibouti a enregistré un déficit de 73% des précipitations moyennes annuelles par rapport à la moyenne de 30 ans (1981-2010). Pour caractériser la sécheresse actuelle, nous analysons une série pluviométrique reconstruite pour Djibouti-Ville de 1901 à 2013, les données de terrain permettant d’illustrer les impacts de ces variations pluviométriques. Les précipitations enregistrées à Djibouti ne présentent aucune tendance sur le long terme (1901-2013). Par contre, ces dernières années montrent une très grande variabilité: le suivi de la moyenne pluviométrique sur …
Modeling Transit Flow Through Port Gates and Connecting Channel in Baltic Sea—Liepaja Port—Liepaja Lake System
2021
This study investigates a water transport features by extending Copernicus Marine Environment Service (CMEMS) to the Liepaja coast-port-channel-lake system with a two-way nested model. The Liepaja lake and Liepaja port are connected by Trade channel. The Liepaja port has three gates—the openings in wave breakers connecting the port aquatory with the Baltic sea. Each of gates has a corresponding dredged channel for securing the navigation. A hydrodynamic model is set up to study the flow and water level in this system. The area of the port gates, port and Trade channel are resolved by 33 m grid. The model results are verified against currents and sea level observations inside/outside port, T…

La scelta delle piante destinate al verde ornamentale tra percezioni e cambiamenti: Anthosart green tool, uno strumento per conoscere, selezionare, a…
2019
The presence and importance of plant life on the planet does not seem to reach our sensory perception, therefore activate reactions of interest, and correct ecological behaviour. The increasing number of extinct species witnesses the human oblivion towards ecosystems. The concept of plant blindness describes the phenomenon that produces significant consequences on nature conservation. Urban green infrastructure, part of our daily life, is the right place to re-connect with plant systems. Designing and creating “built green” by means of nature-based solutions and local species pool is the main goal of Anthosart green tool, a free and user-friendly on-line tool, which can be useful for design…
Flora e vegetazione della Riserva Naturale Orientata "Laghetti di Marinello" (Sicilia nord-orientale)
2011
Flora and vegetation of Natural Reserve “Laghetti di Marinello” (North-Eastern Sicily) - Flora and vegetation of the Natural Reserve “Laghetti di Marinello” (Patti, NE Sicily) are examined. in this area extending 414 hectares, different environmental aspects enabled the emergence of various types of vegetation. The plant-communities are represented by halophilous communities (Juncetea maritimi), riverine hygrophilous communities (Phragmito-Magnocaricetea), psammophilous coenoses (Ammophiletea, Cakiletea maritimae), chasmophytic coenoses (Asplenietea trichomanis), woody and nanophanerophytic coenoses (Quercetea ilicis), and steppic prairies (Lygeo-Stipetea). The floristic analysis testifies …
