Innovazione e rigenerazione delle direttrici di transumanza. Lineamenti per la costruzione di un'infrastruttura verde

Le infrastrutture verdi rappresentano l’evoluzione di “greenways” e “reti ecologiche”, con le quali condividono obiettivi di tutela per habitat e specie, propositi estetico-ricreativi e assetti spaziali interscalari. La parola “infrastrutture” sottolinea da un lato la prospettiva di lunga durata verso la quale sono impostate, dall’altro il ruolo strategico oggi riconosciuto alla pluralità di usi e funzioni sostenibili che sono destinate a ospitare. Tali prestazioni oggi sono identificabili all’interno delle differenti categorie di “servizi ecosistemici”, concetto sviluppato a partire dalla fine del secolo scorso per fornire una valutazione economica ai benefici ottenuti dal “capitale naturale” e dalle attività umane che ne garantiscono la conservazione. Obiettivo della ricerca è mettere in evidenza le numerose potenzialità espresse in questo senso dalla riattivazione della transumanza lungo le proprie direttrici storiche: il vasto e prezioso patrimonio materiale-immateriale da essa ereditato, l’eterogeneità dei paesaggi attraversati e il ruolo di “infrastruttura critica” pre-industriale rappresentato dall’economia laniera costituiscono per molti versi un modello ante-litteram di sostenibilità a cui rifarsi per la costruzione di sistemi multifunzionali integrati

Transhumance heritage in the bioregional perspective

The worldwide dynamics of the last thirty years are outlining opaque scenarios and forcing contemporaries to search for a catharsis whose urgency can no longer be postponed: cultures, economies and ecological balances in their current state are in danger of collapsing at an unprecedented rate. Nevertheless, it is possible to draw from the past references capable of updating consolidated paradigms, rediscovering approaches oriented towards the long term aimed at maintaining the conditions that have allowed progress and well-being for a large part of our species. The millenary practice of transhumance, today relegated to marginal contexts, is one of these: the extensive breeding of livestock, conducted on foot over long distances in search of pastures, is an exemplary adaptation to the scarcity of resources provided by the natural succession of seasons. In contrast, the problems arising from industrialised forms of animal husbandry are highlighted by numerous studies. The regeneration of the vast material and immaterial heritage inherited from transhumance, on the other hand, can provide answers to environmental, ethical and social issues that afflict every continent today: an ante litteram model of sustainability that finds in bioregional planning a concrete prospect of re-actualisation

Sistema de Información Geográfica tipológico para el conocimiento y la conservación del patrimonio construido: un caso de estudio en el sur de Italia

[EN] A typological GIS is a system designed to store, analyse, manage and visualize geo-referred data about the built environment. It allows interactive queries to explore spatial relationships between buildings, improving the knowledge of the built heritage at different scales. For example, by running space-typological analysis, it is possible to extract information about the most used typologies in the existing buildings at different levels, from the urban scale to the construction detail. This knowledge shows a great potential in building design applications and may provide support for a correct design in urban renovation projects aimed to keep the character of the considered area unchanged and preserve its cultural and historical value. This work presents the first phase implementation of the typological GIS of an historical city centre set north of Naples and shows some examples of possible GIS queries for typological investigation of built environment at different detail levels.[ES] Un SIG (Sistema de Información Geográfica) tipológico, es un sistema diseñado para almacenar, analizar, gestionar y visualizar datos geo-referenciados sobre el entorno construido. Permite consultas interactivas para explorar las relaciones espaciales entre edificios mejorarando el conocimiento del patrimonio construido a diferentes escalas. Realizando un análisis espacio-tipológico, es posible extraer información de los edificios existentes sobre las tipologías más utilizadas a diferentes niveles, desde la escala urbana hasta el detalle constructivo. Este conocimiento, podría servir de apoyo para un correcto diseño en los proyectos de renovación urbana destinados a mantener inalterado el carácter de la zona considerada y preservar su valor cultural e histórico. Este trabajo presenta la primera fase de implementación del SIG tipológico de un centro histórico situado al norte de Nápoles, y muestra algunos ejemplos de posibles consultas del SIG para la investigación tipológica del entorno construido a diferentes niveles de detalle.This work has been developed within the SEND intra-university project, financed by the "V:ALERE 2019" funds (VAnviteLli pEr la RicErca) by the University of Campania "L.

The Holocene Evolution of the Volturno Coastal Plain (Northern Campania, Southern Italy): Implications for the Understanding of Subsidence Patterns

In the Mediterranean area, several alluvial coastal plains, developed after the Holocene transgression, are affected by subsidence. The Volturno alluvial‐coastal plain, along the eastern Tyrrhenian Sea (southern Italy) is characterized by subsidence rates determined through InSAR data analysis and ranging between 0 and <−20 mm/yr in an area of about 750 kmq across the Volturno River. Inside this area, the pattern of subsidence shows sites with apparently anomalous localized subsidence. To understand the driving mechanisms of this process, a lithostratigraphic reconstruction was provided focusing on the spatial distribution of the horizons considered weak by a geotechnical point of view; then, the subsidence map was overlain spatially with geological data in a Geographic Information System (GIS) environment. The spatial analysis highlighted the major ground deformation occurring within the outer boundary of the incised paleo‐valley, corresponding to the Holocene alluvial/transitional filling that overlies a compaction‐free Pleistocene basement. Inside this general trend, differential compaction was detected corresponding to the thick occurrence of clay and peat deposits, suggesting that the subsidence rate registered in the plain are due in part to the consolidation of primary settlements of soft and compressible soils that characterize the subsoil of these areas, and in large part to the secondary consolidation settlements

The European transhumance network

The lockdown caused by the Covid-19 outbreak was an involuntary socio-environmental experiment demonstrating that the conditions exist to pursue alternative solutions to our short-sighted economic-productive system.Long neglected themes have returned to the center of the debate: the potential of inland areas in the policies of redistribution of settlement density; the value, not only cultural, of secondary historical settlements; the enhancement of ecosystem services due to large-area environmental systems; the role of urban spaces and proximity green spaces for the sustainability of dense settlements.For all these issues, the transhumance system has played a central role over time.In this new scenario, the article reports on a research effort aimed at defining a territorial model for the European transhumance network.The territorial system of transhumance, observed according to the taxonomic hierarchy proposed by the research, will be able to constitute a knowledge base for implementing policies for the conservation of customs, traditions, beliefs, food and wine culture, and expression of the pastoral world.Furthermore, the system may become a coherent framework aimed at assessing the environmental and landscape sustainability of rebalancing settlement transformations in a climate-proof way, with particular reference to the new mobility strategies and new settlement choices that will become appropriate in the post-pandemic era

Coral Patch and Ormonde seamounts as a product of the Madeira hotspot, Eastern Atlantic Ocean

New detailed swath bathymetry and bottom samples from Coral Patch and Ormonde seamounts provide constraints on the emplacement of the Madeira hotspot in the Eastern Atlantic Ocean. Swath bathymetric data document that Coral Patch is a composite structure, made up of at least nine distinct volcanic centres. Lithified pelagic carbonates infilling fissures in lava blocks constrain a minimal age for the volcanism in the Early Miocene and represent the first documentation of Coral Patch acting as an offshore terrigenous-starved seamount. At Coral Patch, as already observed at the Ormonde seamount, volcanism was emplaced on top of a pre-existing relief resulting from the regional tectonic compressive regime

How the First Year of the COVID-19 Pandemic Impacted Patients’ Care in the Vascular Surgery Divisions of the Southern Regions of the Italian Peninsula

Background: To investigate the effects of the COVID-19 lockdowns on the vasculopathic population. Methods: The Divisions of Vascular Surgery of the southern Italian peninsula joined this multicenter retrospective study conducted through cross-sectional survey. Each received a 13- point questionnaire, investigating the hospitalization rate of vascular patients in the first 11 months of the COVID-19 pandemic and in the preceding 11 months. Results: 27 out of 29 Centers were enrolled. April-December 2020 (7092 patients) vs 2019 (9161 patients): post-EVAR surveillance, treatment for Rutherford category 3 peripheral arterial disease, and asymptomatic carotid stenosis revascularization significantly decreased [1484 (16.2%) vs 1014 (14.3%), p=0.0009; 1401 (15.29%) vs 959 (13.52%), p=0.0006; and 1558 (17.01%) vs 934 (13.17%), p<0.0001, respectively]; while revascularization or major amputations for chronic limb-threatening ischemia, and urgent revascularization for symptomatic carotid stenosis significantly increased [1204 (16.98%) vs 1245 (13.59%), p<0.0001; 355 (5.01%) vs 358 (3.91%), p=0.0007; and 153 (2.16%) vs 140 (1.53%), p=0.0009, respectively. Conclusions: The suspension of elective activities during the COVID-19 pandemic caused a significant reduction in asymptomatic carotid stenosis revascularization, treatment for Rutherford 3 peripheral arterial disease, post-EVAR surveillance. Contestually, we observed a significant increase in urgent revascularization for symptomatic carotid stenosis, and revascularization or major amputations for chronic limb-threatening ischemia
