The anthropogenic sealing of soils in urban areas
2009
The sealing of soils by impervious materials is, normally, detrimental to its ecological functions. Exchanges of energy, water and gases are restricted or hampered and an increasing pressure is being exerted on adjacent, non sealed areas. The negative effects span from loss of plant production and natural habitats to increased floods, pollution, and health risks and consequently higher social costs. Environmental Agencies produce periodical reports where the phenomenon of soil consumption by urban infrastructures is monitored with extremely sophisticated geographical tools but little specific research is available that describes the effects of soil sealing. This paper reviews some recent co…
Vitesse, accessibilité et étalement urbain ; analyse et application à l'aire urbaine dijonnaise
2003
The set of themes of the city is approached primarily by the means of the residential density. This concept is analyzed from a purely conceptual point of view, then more theoretical (thus making use of rather traditional econometric models: Clark, Newling) for finally being applied to the agglomeration dijonnaise like with its urban surface. One releases the great urban structures thus revealing an intermediate city between the model monocentric and polycentric. The two components are analyzed successively starting from the concept of residential density. Taking as assumption that the cities are dynamic, the second stage is that of urban sprawl out. A first introductory approach attempts to…

ZERO CONSUMO DI SUOLO: PRIME RIFLESSIONI SUL RE-CYCLE
2013
Il contributo tratta del Re-cycle urbano e territoriale come concreta risposta operativa al consumo di suolo e allo sprawl che caratterizza le città italiane, soffermandosi anche sui disegni di legge in merito al momento in discussione in Parlamento.
Lo sprawl è un delitto
2014
Il contributo si sofferma sul rapporto tra consumo di suolo e dispersione insediativa declinandone le specificità e prefigurando alcune "soluzioni" al soil sealing.
Consumo di suolo. Un approccio multidisciplinare ad un tema trasversale
2014
Il testo affronta il tema "consumo di suolo" affrontando la sfida dei un confronto 'trasversale', affinchè si provi a individuare soluzioni comuni. Per agevolare il confronto interdisciplinare, il testo è suddiviso in due sezioni: teorie del consumo e territori del consumo. La sezione “territori del consumo” analizza casi-studio concreti con contributi di Teresa Cannarozzo, Giuseppe Giunta e Alessandra Giorgianni, Giuseppe Abbate, Filippo Schilleci, Annalisa Giampino, Giuseppe Guerrera, Tommaso La Mantia. La sezione "teorie del consumo" racchiude contributi a carattere teorico-metodologico. Vi si trovano testi di Giuseppina Carrà, Iuri Peri e Carlo Prato, Claudio Bellia, Giuseppe De Luca, N…
Simulating and assessing prospective scenarios
2008
The first part of the paper is centered on the phenomena of urban growth, in order to set the rules for a sustainable scenario of urban development. Then we enter the core of the paper that is the comparison of models. For each of the three compared models, we describe its main theoretical characteristics, the chosen parameters, and the obtained results. In section 6, heterogeneity of the produced results is discussed, and we highlight the points of interest and the lacks of the three models. Here we show that results we obtained feed debates about urban growth management. Finally, concluding remarks at the end of the paper address the general topic of the evaluation of the quality of simul…
Land Consumption: A Multidisciplinary Approach to a Cross-Cutting Theme
2016
The idea of the book emerged from one-day conference with the title: The Consumption of Land and Urban Renewal from Agrigento and its Hinterland], held in May 2012 in Agrigento, Sicily, organised by the author. The conference, which saw the participation of interested citizens, has provided the opportunity to inform and raise awareness among the general public about the international issue of land consumption, starting from an analysis of the local situation, marked by its best-known variation: urban sprawl.
