Urban landscape evolution as a consequence of an invasive pest: The case of a small sicilian town
2017
The Red Palm Weevil (RPW), after its accidental introduction in Italy in 2005, determined a progressive disruption of Canary palms mostly in the central and southern regions. As it is difficult to undertake the management of this pest, the possibility of substituting the killed/symptomatic palms with other ornamental trees has been recently discussed. In this context, understanding the citizens' needs about green areas can improve the management of public parks and urban greening. Involving citizens on the natural resource management using public participation processes is crucial. The case study of a small town of Sicily (Italy) was treated and the spread of this pest was monitored. Moreov…
Functional diversity of different vegetation types does not respond homogeneously to change over time after conservation translocation from a rural l…
2019
Abstract The anthropogenic impact on natural environments and the loss of species diversity along with changes in functional diversity call for effective steps to ensure habitat conservation. The functional diversity in particular has suffered in recent decades due to investment and land use changes. The translocation of whole turfs of certain vegetation plots prior to being destroyed is one possible solution for maintaining habitat functional diversity. In the presented paper, we analyse the functional changes in adaptive, regeneration and urbanity plant traits for meadow, heath and fen that were translocated from a rural site to a post-industrial site in a city. After five years of monito…
A Systematic Literature Review of Historic Garden Management and Its Economic Aspects
2020
Historic gardens are important parts of humanity’s built heritage within the designed landscape, providing many environmental, economic and socio-cultural benefits. Management is a key part of their conservation, perhaps the most difficult because it is costly, must be continual, and requires a skilled workforce. This systematic review looks at the literature addressing historic garden management, with special attention regarding the social, economic and environmental aspects of sustainability. Academic studies on this subject come from many different disciplines, making it both stimulating and fragmented. It is now time to consolidate these interdisciplinary efforts into a clear vision, in…
The Value of the Useless in the Urban Landscape of Small Islands
2015
Abstract. In the variety of the Italian landscape-cultural mosaic, the morphology of Favignana (Egadi Islands) is the outcome of the long-term relationship between natural environment and human actions that has drawn both natural and urban landscape. This relationship, that constitutes the Favignana’s architectural and landscape heritage, is often denied or forgotten because of transformations caused by a new demand of efficiency (usefulness?) in reference to an economic policy based on the tourism-related activities. In this case-study, the Analytic Network Process (ANP) (selected among the Multicriteria Analysis techniques because of its holistic approach) has applied to support the choic…
Arcadio Blasco: : Cinco esculturas urbanas (1986-1991)
2013
Con las primeras elecciones municipales democráticas en España después del franquismo, los nuevos ayuntamientos establecieron programas para reconstruir las ciudades españolas. Un aspecto de estos proyectos fue la creación de espacios públicos donde la gente pudiera encontrarse en un ambiente agradable. Estas áreas se cerraron al tránsito y se amueblaron con árboles, bancos y un nuevo tipo de esculturas artísticas. En la zona de Alicante, el ceramista Arcadio Blasco, ya conocido en Madrid y en Roma, creó cinco monumentos urbanos de gran escala. Después de veinte años, el destino de cada escultura ha sido diferente: alguna permanece en buenas condiciones, pero otras han sido tratadas de tal …
Sustainable Urban Requalification: Circularity of Processes for a New Metabolism
2014
Through this paper we present the first results of a research combining the management problem of Municipal Solid Waste to the requalification of built environment. The goal of this research is to mitigate the vulnerability of territory and urban heritage and to transform a problem into opportunities. Above all, we have paid attention to several exemplifying cases of Italian territory: suburbs of large towns, historical centres, small centres (and, in particular, those with a strong historical connotation). Their features are, at the same time, restrictions and challenges for designing new compatible systems that can contribute to the requalification of urban landscape recovering spaces wit…
Apport d'un formalisme psychologique à la modélisation des préférences individuelles. Application aux choix d'itinéraires pédestres
2007
With the increasing need for a sustainable mobility, pedestrian movement analysis lately increased. In an attempt to get a more detailed knowledge of urban pedestrian movement, we intend to model the pedestrian's route choices. Our first approach is based on simple economic models, the discrete choice models. A psychological theory is added in the process in order to improve the pedestrian behaviour simulation. Results show that psychological formalisms are useful for individual choices' modelling. For this reason they could be used more systematically in the framework of urban mobility
Past and Future: The Urban Landscape and the Virtuous Management of Resource Flows for a Sustainable Environment
2022
A circular process in the case of resource flows can best be expressed according to a plan that takes into account the geographical proximity and synergy between citizens and industries. The study hypothesizes the possibility of anticipating part of the recycling processes in residential urban areas. This streamlines the work phases and consumers become an active part of the process. Circular management of resource flows is an operational problem that emerges with greater severity in an urban landscape, due to the constraints generated by road networks and the need to protect basic values. It often happens that the degradation generated by the irresolute nature of the technical environmenta…
The Urban Landscape and the Real Estate Market. Structures and Fragments of the Axiological Tessitura in a Wide Urban Area of Palermo
2016
The proposed study deals with the urban landscape of Palermo and its possible representation from the perspective of the real estate market analysis. Real estate is one of the most significant types of capital asset and the wide range of its possible utilizations makes complex the interpretation of the market phenomena. The multi-layered reality of such a large city (represented through the sample of 500 properties) needs to be articulated into a significant set of sub-markets in order to outline the complexity and to map the distribution of homogeneous groups of properties within the whole city area. The comparison between quality and price within each cluster allows us to elicit the degre…
A Comparison of Advanced Regression Algorithms for Quantifying Urban Land Cover
2014
Quantitative methods for mapping sub-pixel land cover fractions are gaining increasing attention, particularly with regard to upcoming hyperspectral satellite missions. We evaluated five advanced regression algorithms combined with synthetically mixed training data for quantifying urban land cover from HyMap data at 3.6 and 9 m spatial resolution. Methods included support vector regression (SVR), kernel ridge regression (KRR), artificial neural networks (NN), random forest regression (RFR) and partial least squares regression (PLSR). Our experiments demonstrate that both kernel methods SVR and KRR yield high accuracies for mapping complex urban surface types, i.e., rooftops, pavements, gras…
