Dialoghi fra storia e disegno: il progetto di Enrico Del Debbio per la Casa del Balilla di Enna

2022

Attraverso il rapporto dialogico tra due diverse discipline afferenti al campo dell’architettura, come la storia e il disegno, in questo saggio si tenterà di indagare un’opera sconosciuta di Enrico Del Debbio, realizzata difformemente rispetto all’ipotesi progettuale: la Casa del Balilla per la città di Enna. Il progetto originario dell’architetto carrarese sarà ricostruito digitalmente a partire dall’esaustiva documentazione grafico-progettuale ritrovata presso il MAXXI di Roma. Un processo esegetico durante il quale si porterà alla luce un frammento finora inedito, quantunque infinitesimale della storia dell’architettura italiana, mediante l’applicazione combinata degli strumenti della Sc…

Resistenze imperfette. Trasformazioni socio-spaziali a Ballarò (Palermo)

2019

Nel marzo del 2016 l’Aula Magna del Liceo B. Croce, storico istituto sito nel centro di Palermo non lontano dal mercato rionale di Ballarò, è luogo di un accordo che avrebbe segnato in profondità il destino di alcuni degli spazi che compongono il quartiere. È qui, infatti, che il processo di riappropriazione e riqualificazione di Piazza Mediterraneo, cominciato cinque anni prima, trova un riconoscimento formale da parte del Comune e delle istituzioni – scuole, parrocchie, associazioni – che lavorano sul territorio. Promotrice di questo processo è l’associazione SOS Ballarò, un’assemblea pubblica che riunisce attori eterogenei e che ha come obiettivo il rilancio del mercato e la riqualificaz…

Are calanco landforms similar to river basins?

2017

In the past badlands have been often considered as ideal field laboratories for studying landscape evolution because of their geometrical similarity to larger fluvial systems. For a given hydrological process, no scientific proof exists that badlands can be considered a model of river basin prototypes. In this paper the measurements carried out on 45 Sicilian calanchi, a type of badlands that appears as a small-scale hydrographic unit, are used to establish their morphological similarity with river systems whose data are available in the literature. At first the geomorphological similarity is studied by identifying the dimensionless groups, which can assume the same value or a scaled one in…

Geodiversity and geoheritage: Detecting scientific and geographic biases and gaps through a bibliometric study

2019

Abstract Many scientists have recognized that there is diversity in nature, including biodiversity, geodiversity, and pedodiversity. Studies in biodiversity date back as far as the 1700s, but geodiversity and pedodiversity studies are much more recent, dating to the late 1970s to early 1980s. Given that we are now approaching 40 years of geodiversity and geoheritage work, this study was undertaken to determine areas that have been well addressed and where current gaps are. This was accomplished by reviewing the publications in the journal “Geoheritage”, the Scopus and Google Scholar databases, and established geoparks according to UNESCO records. It was found that geodiversity studies typic…

Runoff initiation, soil detachment and connectivity are enhanced as a consequence of vineyards plantations.

2017

[EN] Rainfall-induced soil erosion is a major threat, especially in agricultural soils. In the Mediterranean belt, vineyards are affected by high soil loss rates, leading to land degradation. Plantation of new vines is carried out after deep ploughing, use of heavy machinery, wheel traffic, and trampling. Those works result in soil physical properties changes and contribute to enhanced runoff rates and increased soil erosion rates. The objective of this paper is to assess the impact of the plantation of vineyards on soil hydrological and erosional response under low frequency - high magnitude rainfall events, the ones that under the Mediterranean climatic conditions trigger extreme soil ero…

An economic, perception and biophysical approach to the use of oat straw as mulch in Mediterranean rainfed agriculture land

2017

[EN] Soil erosion is a key cause of land degradation in agriculture lands; and it is a worldwide threat that must be solved by means of nature-based strategies to be able to achieve sustainability. The use of mulches can be a solution, but there is a lack of information on long-term effects of the use of straw. Furthermore, little is known about the perception of farmers and the economic cost on the implantation of straw as a conservation measure. Eight paired plots were selected in Sierra de Enguera on an agriculture field to determine the effect of straw cover on soil erosion. Four plots were tilled three times per year (Control) and four plots were not ploughed and 0.125 kg m(-2) y(-1) o…

Nature and origin of fault-controlled fluid seepage across the Maltese Islands

2018

The Maltese Islands are intersected by two major fault systems associated with two diverse rifting episodes affect the islands. The first and most widespread system is Early Miocene to mid-Pliocene in age, and consists of faults that are orientated ENE-WSW. The most distinct of these faults is the Great Fault (known also as the Victoria Lines Fault). The younger system of faults (Late Miocene-Early Pliocene) is still active and consists of faults striking NW to SE that often cross-cut the first generation of faults. The most extensive of these faults is the Maghlaq Fault, located along the southern coastline of the Maltese Islands.

Geografías de la pandemia COVID-19 en España : el retorno del medio rural

2022

La pandemia de la COVID-19 ha supuesto en España la peor crisis de salud pública, económica y social desde la Guerra Civil. El virus ha causado miles de muertos y cientos de miles de infectados, con Cataluña y Madrid como territorios más afectados. Un primer análisis exploratorio muestra, con los pocos datos hasta ahora disponibles y fiables, que esta pandemia ha tenido una especial incidencia en los territorios urbanos con mayor densidad de población y niveles más elevados de contaminación, mientras que las áreas rurales, a pesar de tener mucha más población de riesgo y un sistema sanitario mucho más precario, han mostrado ser mucho más resilientes a la expansión del coronavirus. Todo ello…
