Describing urban soils through a faceted system ensures more informed decision-making

2016

Urban areas are increasing worldwide at a dramatic rate and their soils definitely deserve more attention than they have received in the past. In urban environments, soils potentially provide the same ecosystem services as in rural and wild environments, although in some cases they are depleted of their basic functions, such as when they lose their productive and filtering capacities because of sealing, and become mere supports for infrastructures. In other cases, soils of urban areas acquire new functions that are unique to these environments. Current soil classifications fail to effectively account for the complexity of urban soils and the information that is required for their management…

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…

Le esposizioni universali: spazialità e politiche di rappresentazione

2015

Come possiamo parlare di modernità? Riflettere su un fenomeno come le Esposizioni universali, sulla loro storia, sembra una buona pista per rispondere alla domanda iniziale. Questi spazi spettacolari, inventati nel XIX secolo dalla società occidentale, producono eventi: “montano” città. E’, infatti, il montaggio una delle chiavi che permette di cogliere questo senso di trasformazione che le Esposizioni producono. Il montaggio come elemento della tecnica e come elemento metaforico. Le Esposizioni si presentano come spazi dove il tutto e le parti sono messi in mostra; sono pensate come forme di inventario, di archivi atti a educare e a meravigliare ma il loro significato va oltre le aspettati…

Ethical E-Participation

2015

The most recent forms of e-participation seem to provide new issues that need to be discussed. One such discussion involves the role of GIS. Can an ethically aware GIS be conceived? What does it mean for a GIS to be ethical at all? Throughout this paper, first the authors create a theoretical framework to encompass four key elements that lead us to the definition of ethical digital mapping: GIS ethics, social justice, power, and participation. Then they introduce the concept of PPGIS (Public Participation GIS), and argue that only a ‘qualitative turn' can enhance their importance in decision-making processes. Finally, the authors discuss an experiment that is currently taking place in Paler…

Walking through Dangerous Neighbourhoods: Ethics and Qualitative Research in Palermo

2013

“Ethical considerations are clearly important in the practice, subject matter and research priorities of geography. […] Cultivating a dialogue on ethics […] contributes to us becoming more fully conscious human beings” (Routledge, 2010: 399). This presentation implies that ethics must become an important topic to be discussed in geographic qualitative research. The case study is an action-research project, which took place in Palermo focusing on the way different neighbourhoods are nowadays perceived in the city. A particularly significant case presented is the (in)famous ‘ZEN’ neighbourhood: in 2005, some Dutch college students came to Palermo to visit the ZEN neighbourhood, and were accom…

Mapping snow density through thermal inertia observations

2023

Snow, as a fundamental reservoir of freshwater, is a crucial natural resource. Specifically, knowledge of snow density spatial and temporal variability could improve modelling of snow water equivalent, which is relevant for managing freshwater resources in context of ongoing climate change. The possibility of estimating snow density from remote sensing has great potential, considering the availability of satellite data and their ability to generate efficient monitoring systems from space. In this study, we present an innovative method that combines meteorological parameters, satellite data and field snow measurements to estimate thermal inertia of snow and snow density at a catchment scale.…
