A new mathematical model for environmental monitoring and assessment

Versão dos Autores para este artigo.In this paper we are concerned with a quantitative method of Landscape Ecology. More in details we consider an environmental system distributed in landscape units (ecological sectors) and we propose a new mathematical model in order to implement a method for the evaluation of the ecological state of the system under investigation. After having performed a stability analysis of the model, we apply the proposed procedure first by considering separately each landscape unit and then extending our investigation to the system as a whole, by taking into account the connections between all the landscape units themselves. Our investigation includes some numerical computations that were performed for a Northern district of the Turin Province, using an approximation procedure that should avoid stiffness problems.National Group GNFM of INdAM, Italyinfo:eu-repo/semantics/publishedVersio

Mathematical models in landscape ecology: stability analysis and numerical tests

Si presentano vari modelli matematici per la valutazione della qualita' ecologica di un sistema ambientale. Si presenta poi un nuovo modello denominato PANDORA 2.0 e si mostra un'applicazione nel territorio della provincia di Viterb

The sustainability of the urban system from a hydrological point of view: a practice planning proposal

Environmental protection issues are often considered as a toll to be paid and not as a proactive development engine in urban planning. The issue of green areas needs to be re-interpreted as a real infrastructure, which is able to provide tangible benefits to the health and safety of citizens. These aspects represent fundamental issues of the applied research, which should explore methods and techniques able to provide the ecological concerns with the ability to operate efficiently. This paper aims to provide an answer to these questions focusing the attention on the greenery in the city and on one of its most important ecosystem services, which is mitigation of flooding events. The experimentation was carried out in an urban area, verifying, in quantitative terms, the role of the green, engineered with some SUDS, to mitigate the hydrological alteration that the urban development involves. Finally, two proposals have been presented to move from traditional planning based on normative standards to a more flexible, site-specific performance-based planning

Detection of Landscape patterns in airborne LIDAR data in the Nature Reserve of Castelporziano (Rome)

During the last decades the protection of nature has become a very important aspect due to the anthropogenic interference and structural alteration of the environment, especially in the peri-urban areas. Therefore, for a sustainable forest planning it is fundamental to get information about the actual state and the variation in landscape patterns concerning the forest layers. To this aim, an airborne laser scanning (LIDAR), a type of sensor which explicitly measures canopy height, was used to detect landscape patterns of broadleaf oak forest and for detecting the monumental trees in a peri-urban Natural Reserve: the Presidential Estate of Castelporziano (Rome)

Reducing urban entropy employing nature-based solutions: The case of urban stormwater management

Despite numerous studies on urban resilience, few practical applications of spatial explicit and quantitative resilience indicators in green infrastructure planning are present in literature. This paper presents a methodological framework to assess the hydrological resilience of an urban context employing modelling approach. The proposed resilience index is then used to support the definition of nature-based and engineered solutions aimed to increase resilience to floods as well as to enhance the green infrastructure multi-functionality in a densely populated district of Bari. The paper aims then to contribute to the introduction of resilience assessment and sustainable storm water management in practice urban planning in a context of climate adaptation plans
