Reviewing the role of ecosystems services in the sustainability of the urban environment: A multi-country analysis

2020

The urban environment is characterised by many pressures caused by population growth, transport (and its related emissions), and the damage to green areas. Yet, there is a variety of ecosystem services available in urban areas, which may be deployed to ameliorate the current problems and foster their sustainability. This paper reviews the role of ecosystem services as tools for sustainability, based on an urban setting. It also describes a series of multi-country case studies, where an assessment of their functions using a set of benefits valuation approaches such as health benefits, economic benefits, social benefits and benefits to climate resilience, are provided, along with an appraisal…

Bryophyte investigations in urban areas: diversity of bryoflora of Erice town.

2016

This work is part of a study of bryophyte floras of Sicilian towns that has highlighted the presence in these environments of interesting taxa from the taxonomic and phytogeographical point of view (1, 2, 3, 4). Given its location, perched at 750 m a.s.l. on the S. Giuliano Mount at the northwestern tip of Sicily, the town of Erice has a climate which, although typically Mediterranean, has a strong wet connotation for the frequent presence of fog, especially in the winter time. These features contribute to creating conditions particularly suited to host bryophytes that grow both on artifacts and on phorophytes present in the city and specially in the Balio urban park. The study has allowed …

Dry deposition of particle on urban areas

2019

Abstract Dry deposition process is recognized as an important pathway among the removal processes of radioactive pollutants in atmosphere. There is not a unique and accepted theoretical description of involved dry deposition phenomena due to the complexity of the fluid-dynamic processes that influence the deposition flux, but also because there is a lack of experimental data covering all scenarios of interest. In this paper, that is the result of a National Research Program a research activity conducted by DEIM Department of the University of Palermo and ENEA and funded by the Italian Minister of Economic Development, a new schema for parameterization of particle dry deposition velocity on …

Landslide inventory and rockfall risk assessment of the Monte Pellegrino Oriented Nature Reserve area (Sicily)

2018

In the last 20 years the natural oriented reserve of Monte Pellegrino is affected by several rockfall events. This sector of the Northern Sicily is a strategic urban area and represent the most important element of both the religious and cultural tradition and landscape for the city of Palermo.The rockfalls are here the major natural threats and represent a relevant risk of people, structures and infrastructures and prevents the economic and social development that could be made by high tourist potential of the area. For the above mentioned reasons a detailed geological and geotechnical study in order to define a quantitative risk analysis is now being carried out, concurrently with the imp…

Regional deprivation and non-cancer related computed tomography use in pediatric patients in Germany: Cross-sectional analysis of cohort data.

2016

BACKGROUND: Conflicting findings were observed in recent studies assessing the association between patients' area-level socio-economic status and the received number of computed tomography (CT) examinations in children. The aim was to investigate the association between area-level socio-economic status and variation in CT examination practice for pediatric patients in Germany. METHODS: Data from Radiology Information Systems for children aged 0 to < 15 years without cancer who had at least one CT examination between 2001 and 2010 were extracted in 20 hospitals across Germany. The small-area German Index of Multiple Deprivation (GIMD) was used to assess regional deprivation. The GIMD …

Contributo alla conoscenza degli effetti dell'inquinamneto atmosferico su foglie di Eucalyptus camaldulensis ed E. Globulus (Myrtaceae)

2012

Contribution to the knowledge of air pollution effects on Eucalyptus camaldulensis and E. globulus (Myrtaceae) leaves -.This study deals with the metal storage found in Eucalyptus camaldulensis and E. globulus leaf structures. The cytological and chemical analysis were carried out on samples from the city of Agrigento and its surroundings. The investigation pointed out that the the most evident alterations are phenolic storage and distinctive cellular modification. These features appear related to the greater presence of trace elements within the sites that are more exposed to intense vehicular traffic. Winter samples, moreover, have more evident structural modifications due to a bigger con…

Comparison of professional plans of students from rural areas and cities in terms of economic mentality

2017

Process of globalization, rapidly progressing nowadays, can cause conflicts between cultural norms and values valid in a globalized society and local values. Similar mechanism may occur on a smaller scale, where culture characteristic of urban centers and rural areas may clash. The purpose of this article is to establish what is the economic mentality of students at the Faculty of Economics of the University of Opole from rural areas and cities by comparative analysis of one of its components - work. The article presents a fragment of own research conducted in April 2016 year. Research is an introduction to the wider research into the economic culture of rural areas. In the course of testin…

Variability of the Level of Development of Functopnal Urban Areas

2018

Miejskie obszary funkcjonalne mają istotne znaczenie w realizacji zarówno Krajowej Polityki Miejskiej 2023, jak i terytorialnej polityki rozwoju. Celem badania jest określenie poziomu rozwoju obszarów funkcjonalnych miast wojewódzkich Polski. Badania przeprowadzono z wykorzystaniem metody taksonomicznej w ujęciu dynamicznym obejmującym okres 2005-2015. Podstawę wyznaczenia wielkości taksonomicznych stanowił zestaw wskaźników diagnostycznych ujętych w trzech wymiarach rozwoju: społecznym, gospodarczym i środowiskowym. W ramach badania została podjęta ocena poziomu rozwoju miast centralnych MOF oraz oddzielnie miast i gmin ich otoczenia. Dodatkowo określono poziom rozwoju każdego z wymiarów r…

A Choquet Integral Based Assessment Model of Projects of Urban Neglected Areas: A Case of Study

2014

This paper describes a multi-criteria evaluation model to support decisions related to the redevelopment of urban residual areas, a central theme in planning practices. Renewal projects on urban or neighborhood scale are complex problems because of the social, economic and environmental implications generated on the different categories of stakeholders. In the awareness of the specific characteristics of each city, the cognitive and evaluation model is especially defined for a given urban context, although it is easily adaptable to different urban ones. In order to take into account the interactions among the criteria by which we compare design alternatives, the Choquet integral is implemen…
