CARATTERIZZAZIONE DI COMUNITÀ A CRUCIANELLA MARITIMA E RELAZIONI CON LA COMPONENTE BRIOFITICA
No full textOggetto del presente lavoro sono le comunità a Crucianella maritima primarie delle dune costiere e gli orli a briofite ad esse adiacenti. Si vuole evidenziare il contatto di tipo seriale tra comunità briofitiche e crucianelleto al fine di meglio definire in chiave floristica, ecologica e dinamica l’habitat 2210
NbS a diverse scale per problemi complessi: il caso di Civita di Bagnoregio (VT)
No full textSoil and water Bioengineering is a discipline founded on Nature Based Solutions.
If it remains faithful to its principles, it can set itself ambitious goals.
The masters of the discipline have always recommended that a careful botanical
analysis be carried out before intervening, so that the most suitable native species
can be chosen for the intervention. This contribution aims to support two hypotheses:
1) a study of vegetation attentive to its dynamism allows us to rationalize
the choice of the most suitable plant species. 2) a localized intervention may not
be sufficient if the problem is on a territorial scale. Civita di Bagnoregio (Central
Italy) is a suggestive medieval village of Etruscan origin that has inspired artists
from all over the world. Civita has a marked destiny: it was built on an ignimbritic
flow that rests on highly erodible clays and, over the centuries, has seen the
urban site gradually shrink. The landscape that surrounds it, the large expanses of
gullies, heralds what is destined to become what remains of the ancient city. Our
goal is to push this moment away as much as possible
Ecosystem Indicators and Landscape Ecology Metrics as a Tool to Evaluate Sustainable Land Planning in ICZM
No full textIn the frame of Integrated Coastal Zone Management (ICZM)
planners need tools to design and assess a sustainable state for the coast. Sustainability
and progress indicator have to be integrated to identify improvements
in the state of coastal zones as a result of ICZM implementation [1].
There are two useful approaches in order to take into account, system property,
complexity and evolution, and integrating humans and bio-geospheres:
system ecology (and ecosystem health concepts, as defined in [2]) and landscape
science and ecology (as defined for example in [3–7]). The holistic approach in
the context of human-nature relations is the real challenge of modern landscape
ecology. It regards the background of increasing environmental problems and
the discussion about sustainability [4] and for sustainability planning [8].
In the paper, it is proposed a brand new synthetic ecosystem indicator suited to
monitoring regeneration plans of coastal zones: the Land Eco-Biodiversity. In order
to have more benchmarks in assessing the state of implementation of a strategy, the
plan, as well as from an ecosystemic point of view, is measured from a landscape
point of view through Landscape Ecology indexes. In fact, the fragmentation of the
landscape is part of the resource efficiency indicators defined by Eurostat in the
context of monitoring the main objectives defined in the Europe 2020 strategy in the
Category: “Nature and ecosystems | Biodiversity”.

No full textIn the paper, we present a Planning Framework for Integrated Coastal Zone Management (ICZM). The points of strength of the framework are the following:- It is an iterative and participatory process;- It is scenario-based and model-based;- It uses a Spatial Decision Support System (SDSS) as enabling infrastructure;- The SDSS is "powered" by open data and data systematically updated by public bodies.The theoretical starting point is ICZM requires decision support tools to cope with knowledge from multiple sources, interdisciplinarity and multiple scales (e.g., spatial, temporal or organizational) [1]. The 2007 Integrated Maritime Policy for the European Union [2] is a key document to understand the relationship between coastal and marine information and policy implementation. It shows that it is necessary to develop a marine-coastal Decision Support System [3, 4] based on indicators and indices (aggregations of indicators into a synthetic representation), use of Geographic Information Systems, models and multicriteria assessment of scenarios [5, 6]. The system of indices is used to describe the complexity of a coastal system: geo-ecological level, land processes, human society, economy, and coastal uses at multiple scales [5, 7]. Multicriteria assessment is a tool to support social and environmental decisions in the perspective of sustainability and strategic planning [8-11].During the design phase of the SDSS components (basic data, indicators and models), it was performed a review of the Land Use/Land Cover change simulation models. The output of the review was the choice of SLEUTH model [12]. The framework was tested on a study area (Veneto Region - Italy). In the test we coupled SLEUTH with Fragstats [13] for the analysis of landscape ecology metrics

Full text linkPhytocoenotic originality of the N-Adriatic coastal sand dunes (Northern Italy) in the European context: The Stipa veneta-rich communities.
Full text linkThe particular habitat of Stipa veneta, a priority species of the European Community Directive 92/43, is here described. The phytosociological analysis led to the description of a new association ( Teucrio capitati-Chrysopogonetum grylli), endemic of the N-Adriatic fixed sand dunes. Given the high importance of the species, the conservation of its specific community should be included in a broad protection plan of this unique coastal system in the European context
