The potential of multilayer green roofs for stormwater management in urban area under semi-arid Mediterranean climate conditions
2022
Different low impact development measures have been proposed to make cities more flood-resilient, and recent literature is paying great attention to the evaluation of their direct benefits in terms of flood risk mitigation and the numerous co-benefits that they may offer. This study describes an experimental prototype of a technologically advanced multilayer green roof installed in a Mediterranean urban area (i.e., Palermo, Italy) and explores the results of an analysis of data collected over a one-year monitoring period by a complex sensors network. Multilayer green roofs, or "blue-green" roofs (BGRs), are characterized by a high water retention capacity compared to traditional green roofs…
DETERMINATION OF THE IMPACTS OF LAND USE CHANGE ON WATER BASIN USING REMOTE SENSING AND GEOGRAPHICAL INFORMATION SYSTEM
2016
The population has been increasing as a result of mass immigration in Istanbul. An urbanization process continues and it causes serious increases in urban areas while decreasing the amount of natural environment. This uncontrolled and illegal urbanization accompanied by insufficient infrastructure has caused degradation of cropland and forested areas in the metropolitan area, especially in water basin area. The watershed basins inside the metropolitan area have accelerated the land-cover changes, which have negative impacts on water quality of the basins. The Terkos water basin, one of the seven water basins of Istanbul providing drinking water, was selected as a study area. In order to und…
Potential implications of climate change and urbanization on watershed hydrology
2017
Abstract This paper proposes a modeling framework able to analyze the alterations in watershed hydrology induced by two recurrent drivers for hydrological changes: climate change and urbanization. The procedure is based on the coupling of a stochastic weather generator with a land use change model for the generation of some hypothetical scenarios. The generated scenarios are successively used to force a physically-based and spatial distributed hydrological model to reconstruct the basin response under different conditions. Several potential climate alterations are simulated by imposing negative and positive variations in the mean annual precipitation and a simultaneous temperature increase.…
La costa dels jubilats. La migració nord-europea de persones retirades a la Costa Blanca
2014
Aquest treball investiga la migració internacional de nord-europeus jubilats a la Costa Blanca i la influència que ha tingut en l’expansió urbana d’aquesta àrea turística. Aquest document, a més, analitza les raons per les quals emigren aquests jubilats, que estan principalment relacionades amb el clima i l’estil de vida. També explora els avantatges i desavantatges d’aquesta migració i l’impacte ambiental i paisatgístic sobre la Costa Blanca.
ENVIRONMENTAL AND GEOLOGIC INDUCED RISK: A CASE STUDY IN ALCAMO MARINA (TRAPANI, SICILY)
2009
Human activities often interfere with the natural evolution of the environment, even more so when any rule or criterion of respect for the environment or urban planning is followed. This, in addition to perturb the natural system, determines conditions for geological and environmental risks, particularly when acting on vulnerable areas, poorly suited for urbanization. In the present study, risk conditions for the site of Alcamo Marina, in the territory of the town of Alcamo (TP), are analyzed, which are determined due both to the geomorphologic setting of the territory and to a large number of human interventions. carried out under an irrational approach since the 70s, in this stretch of co…
Effects of climate and land use changes on runoff extremes
2017
The analysis of the hydrological changes and their interacting triggering factors are objectives defined within the Panta Rhei decade 2013-2022. Climate change and urbanization are among the most recurrent causes for hydrological changes at the global level. This work proposes a modeling framework for the analysis of the alterations in the watershed hydrological response and, more specifically, in runoff extremes, induced by such perturbations. A weather generator and a cellular automata land-use change model are used to generate hypothetical scenarios accounting for relevant trends at the global level. Such scenarios are successively considered to force a physically-based and spatial-distr…
Lead concentrations in feathers and blood of common blackbirds (Turdus merula) and in earthworms inhabiting unpolluted and moderately polluted urban …
2006
9 pages; International audience; Despite the dramatic decrease of atmospheric lead (Pb) concentrations in urban areas of most industrialised countries, we hypothesised that urban common blackbirds (Turdus merula) may still be contaminated by Pb concentrations of toxicological concern due to transfer from soil through the food chain. We sampled blackbirds and earthworms, one of their main preys, in Besan?, a middle-size city of Eastern France (where atmospheric Pb concentrations decreased from 0.5 microg/m(3) in 1987 to nearly 0 in 2002) and in a rural reference site. Lead concentrations were determined in the tissues of the different functional groups of earthworms (anecic, epigeous and end…
Synergies in Design and Health. The role of architects and urban health planners in tackling key contemporary public health challenges
2020
Background and aim: Important public health improvements have been achieved over the past decades, but new challenges are emerging and progress cannot be taken for granted. Urban settlements host most of the global population, but they are also sources of several threats. The aim of the paper is to investigate the role of architects and planners in contributing to overcome these critical health challenges and propose strategic actions for collaboration with the public health workforce. Methods: Taking global trends and public health challenges as starting point, a scoping literature review has been conducted to illustrate the possible synergies that architecture and public health workforce …
Cumulative social disadvantage and psychosis: findings from a southern Italy case-control study
2016
Aim: There are consistent evidence suggesting that psychotic disorders are associated to social disadvantage and isolation in adulthood, and research suggested that they these are not simply a consequence of the functional impairment related to onset of the disease (Stilo et al., 2013; Morgan et al., 2008). To date only a few studies have investigated the impact of social risk factors on psychosis in Italy. This study aimed to replicate existing findings in a case-control sample from Southern Italy. Methods: 134 individuals presenting for the first time to mental health services of Palermo (Italy) with an ICD 10 diagnosis of psychosis and 175 population controls from Palermo (Italy) were en…
