Informational analysis of forest landscape spatial heterogeneity
1999
Summary Under the perspective of forest ecosystem management, landscape is interpreted as a functioning structure. From an inventory and monitoring operational point of view, such an approach implies wise use of geographic information systems and remote sensing techniques enabling a global view of the territorial mosaic. From a methodological point of view, landscape ecology theory may be used as the assessment framework. Remotely sensed data provide excellent opportunities for the involved analyses, using both vegetation density measures and spatial statistics. The objective of this paper was to assess landscape spatial heterogeneity using an analysis method based on Shannon's information …
Análisis y tipología de brechas viarias dentro del palimpsesto urbano de València
2020
espanolEl palimpsesto urbano es el resultado de la superposicion y yuxtaposicion diacronica de una serie de modelos de desarrollo urbano que han determinado, en mayor o menor medida, la trama viaria actual. Resultado de esta dinamica, la trama urbana de muchas ciudades presenta una serie de brechas viarias singulares –por sus formas sinuosas, transversales u oblicuas– que dan caracter e identidad al paisaje urbano. En este articulo se analizan –mediante SIG y revision bibliografica– las brechas viarias del palimpsesto urbano, tomando como paradigma el plano de la ciudad de Valencia. Se lleva a cabo tambien una original categorizacion de las brechas viarias de acuerdo a una taxonomia derivad…
Caracterización, Inventariación y aplicación del método de Valoración Biogeográfica de paisajes vegetales (LANBIOEVA) a la comarca de Collsacabra (Gi…
2018
The study presented in this paper takes part of a research project (LANBIOEVA: Landscape Biogeographic Evaluation) carried out for the past 25 years and it is, for now, its last stage. It’s a global landscape valuation method focused on vegetation as a main element of different units that can be evaluated. So far, the use of this method has resulted in numerous works: books, articles, book chapters, communications and presentations, and it has been applied in the study of different temperate and boreal regions of Europe and America. The method has been applied in the study and assessment of diverse vegetation landscapes of the Collsacabra shire (Girona). The objective is to verify its effec…

Neogeografia. Per un nuovo immaginario terrestre
2019
Che senso ha fare geografia oggi, in un’epoca in cui il globo è stato esplorato palmo a palmo e le mappe sono disegnate da satelliti e software? Che importanza ha inventarsi un’immagine della Terra in mezzo ai guasti del clima e alla dissoluzione ambientale? Che cosa possono insegnare alla geografia contemporanea un racconto di mare in latino del X secolo, le canzoni di gesta antico francesi, i diari di bordo del capitano Cartier, la Liguria di Montale, l’India di Moravia e Pasolini, la costa bretone di Kenneth White? Neogeografia è un’esplorazione estrema che mira a un duplice cambio di paradigma: ripensare l’epistemologia della geografia e analizzare i testi come altrettanti laboratori di…
The Potential Geosite of the “Libeccio Antico” Quarries: a Sedimentological and Stratigraphic Characterisation of Ornamental Stone from Mt Cocuccio, …
2018
The Custonaci marble district of western Sicily is known for the production of a valuable ornamental stone that has been, and nowadays is exploited due to its suitable properties and aesthetic qualities. The “Libeccio Antico” was, among the “marbles”, the most appreciated ornamental stone during the Baroque Age (the XVII–XVIII centuries), due to its strong polychrome contrasts from ivory to yellow, green or dark red. This polychrome pattern is the result of dissolution processes that involved an Upper Triassic peritidal limestone. The varicoloured sediments in paleocavities, collapse breccias, paleosols and neptunian dykes that occur in the “Libeccio Antico” represent the peculiar character…
The spatial dimension of the French private rental markets: Evidence from microgeographic data in 2015
2021
International audience; This article draws on data collected by local rental observatories in 12 French urban units in 2015 to analyze the spatial dimension of hedonic rental prices in the private rental market through (i) the spatial heterogeneity between urban units and (ii) the wide variety of contextual and locational characteristics (socio-economic, environmental (dis)amenity, and accessibility) and flexible specifications to capture their potential non-linear influence on rent. Based on a joint test of equality of coefficients across all urban units, we find that hedonic prices differ for 75% of the characteristics, thereby justifying a detailed analysis of heterogeneity.

High rates of short-term dynamics of forest ecosystem services
2021
Currently, the main tools for assessing and managing ecosystem services at large scales are maps providing snapshots of their potential supply. However, many ecosystems change over short timescales; thus, such maps soon become inaccurate. Here we show high rates of short-term dynamics of three key forest ecosystem services: wood production, bilberry production and topsoil carbon storage. Almost 85% of the coldspots and 65% of the hotspots for these services had changed into a different state over a ten-year period. Wood production showed higher rates of short-term dynamics than bilberry production and carbon storage. The high rates of dynamics mean that static snapshot ecosystem service map…
High boreal forest multifunctionality requires continuous cover forestry as a dominant management
2021
Intensive extraction of forest resources lowers biodiversity and endangers the functioning of forest ecosystems. As such, alternative management regimes have emerged, aspiring to promote forest biodiversity and nature protection in managed forests. Among them, continuous cover forestry, (i.e. selective logging), has received considerable attention and is being promoted by some researchers and NGOs. Yet, the full consequences of banning clear-cuts (i.e. rotation forestry) and replacing it entirely with continuous cover forest remains uncertain. We explore how restricting forest management alternatives (either rotation forestry or continuous cover forestry) will affect landscape-scale forest …
