Copernicus high-resolution layers for land cover classification in Italy
The high-resolution layers (HRLs) are land cover maps produced for the entire Italian territory (approximately 30 million hectares) in 2012 by the European Environment Agency, aimed at monitoring soil imperviousness and natural cover, such as forest, grassland, wetland, and water surface, with a high spatial resolution of 20 m. This study presents the methodologies developed for the production, verification, and enhancement of the HRLs in Italy. The innovative approach is mainly based on (a) the use of available reference data for the enhancement process, (b) the reduction of the manual work of operators by using a semi-automatic approach, and (c) the overall increase in the cost-efficiency in relation to the production and updating of land cover maps. The results show the reliability of these methodologies in assessing and enhancing the quality of the HRLs. Finally, an integration of the individual layers, represented by the HRLs, was performed in order to produce a National High-Resolution Land Cover ma
Assessing land take by urban development and its impact on carbon storage: Findings from two case studies in Italy
Land take due to urbanization triggers a series of negative environmental impactswith direct effects on quality of life for people living in cities. Changes in ecosystem services are associated with land take, among which is the immediate C loss due to land use conversion. Land use change monitoring represents the first step in quantifying
land take and its drivers and impacts. To this end, we propose an innovative methodology for monitoring land take and its effects on ecosystem services (in particular, C loss) undermulti-scale contexts. The devised approach was tested in two areas with similar sizes, but different land take levels during the time-span 1990–2008 in Central
Italy (the Province of Rome and theMolise Region). The estimates of total coverage of built up areaswere calculated
using point sampling. The area of the urban patches including each sampling point classified as built up
areas in the year 1990 and/or in the year 2008 is used to estimate total abundance and average area of built up
areas. Biophysical and economic values for carbon loss associated with land take were calculated using InVEST.
Although land take was 7–8 times higher in the Province of Rome (from 15.1% in 1990 to 20.4% in 2008) than in Molise region, our findings show that its relative impact on C storage is higher in the latter,where the urban growth consistently
affects not only croplands but also semi-natural land uses such as grasslands and other wooded lands. The total C loss due to land take has been estimated in 1.6 million Mg C, corresponding to almost 355 million €.
Finally, the paper discusses the main characteristics of urban growth and their ecological impact leading to risks and challenges for future urban planning and land use policies
Inner peripheries : dealing with peripherality and marginality issues within the European policy framework
Inner Peripheries is a complex and often misinterpreted concept, as demonstrated by current scientific evidence. Such complexity derives from the intrinsic peripherality and marginality characteristics of the Inner Peripheries. Despite Inner Peripheries suffer from geographical and socio-economic disparities, their environmental, social and economic potentialities are not fully expressed, and thus can be further strengthened by both the EU Cohesion and Rural Development Policies. However, there is currently a lack of knowledge about the linkages between the Inner Peripheries and both Cohesion and Rural Development Policies, which could limit the effectiveness of planning strategies in these territories. Therefore, through a structured review, we explore the linkages between Inner Peripheries and peripherality and marginality concepts and related criticalities and opportunities. Moreover, we consider the relationships between Inner Peripheries and Cohesion Policy Thematic Objectives and Rural Development Policy Priorities. The main findings show that the Inner Peripheries concept needs to be further explored, especially concerning the environmental aspects. Accordingly, we suggest that great challenges and opportunities currently exist in these territories, and combined policies efforts need to be oriented to strengthen the future sustainable development in the Inner Peripheries.. Key words: Review, Rural Development Policy, Cohesion Policy, Inner Areas. Resumen: Inner Peripheries es un concepto complejo y a menudo mal interpretado, como lo demuestran las pruebas científicas actuales. Tal complejidad deriva de sus intrínsecas características de periferia y marginalidad. A pesar de que las Inner Peripheries sufren de disparidades geográficas y socioeconómicas, sus potencialidades ambientales, sociales y económicas no se expresan completamente y, por lo tanto, pueden ser reforzadas por las Políticas de Cohesión y Desarrollo Rural de la UE. Sin embargo, actualmente existe una falta de conocimiento sobre los vínculos entre las Periferia Interior y las Políticas de Cohesión y Desarrollo Rural, lo que podría limitar la efectividad de las estrategias de planificación en estos territorios. A través de una revisión estructurada, exploramos los vínculos entre las Inner Peripheries y los conceptos de periferia y marginalidad y las críticas y oportunidades relacionadas. Además, consideramos las relaciones entre las Inner Peripheries y los objetivos temáticos de la Política de Cohesión y las Prioridades de la Política de Desarrollo Rural. Los principales hallazgos muestran que el concepto de Inner Peripheries necesita ser explorado más a fondo, especialmente en relación con los aspectos ambientales. Sugerimos que actualmente existen grandes desafíos y oportunidades en estos territorios, y que los esfuerzos de políticas combinadas deben orientarse para fortalecer el desarrollo sostenible futuro en las Inner Peripheries.

Rural areas and urbanization: analysis of a change
After the Industrial Revolution, the precarious equilibrium which regulated the co-evolutionary process between man and nature, has decidedly leaned in favor of a society which is continuously in search of new spaces to be explored and inhabited. According to the data in the Inventario dell’uso delle terre in Italia (Inventory of land use in Italy - Iuti), from 1990 to 2008 land take is estimated at 500,000 hectares; 75% of the time, this occurs to the detriment of farmland. The ability to evaluate and monitor said phenomenon is essential, first of all, in order to provide the decision makers with valid instruments and, secondly, to lay the basis for a new culture which, placing agriculture at the center of a new, regenerative view of the landscape, is able to outline new ways of organizing the territory which take into account the connections between that which is anthropic and the matrix in which it is inserted, in full respect of the principles of sustainable development.In seguito alla rivoluzione industriale, il sottile equilibrio che regolava il rapporto di coevoluzione uomo-natura si è decisamente inclinato a favore di una società alla continua ricerca e conquista di nuovi spazi. Secondo i dati dell’Inventario dell’uso delle terre in Italia (Iuti), dal 1990 al 2008 il consumo di suolo si attesta intorno ai 500.000 ettari e, nel 75% dei casi, esso si verifica a danno dei terreni agricoli. La capacità di valutare e monitorare tale fenomeno è essenziale innanzitutto per fornire strumenti validi ai decision makers e, in secondo luogo, per creare le basi di una nuova cultura, che, ponendo l’agricoltura al centro di una visione rigenerativa dei paesaggi, sia in grado di delineare nuove forme di organizzazione del territorio che tengano conto delle connessioni esistenti tra ciò che è antropico e la matrice in cui esso s’inserisce, nel pieno rispetto dei principi dello sviluppo sostenibile
Le foreste e il sistema foresta-legno in Italia: verso una nuova strategia per rispondere alle sfide interne e globali
Forest management plans as data source for the assessment of the conservation status of European Union habitat types
Natura 2000 is a European network of protected sites that should enable natural habitats to be maintained or restored at a favorable conservation status. Progress toward this objective must be periodically reported by states members of the European Union. We investigated how forest management plans might provide data to support the reporting. The study was done in the forests of the Dolomites and Venetian Prealps, Italy. Here, about 200 forest management plans, divided into several forest compartments, have been drawn up and revised every 10–15 years. Stand structure variables were retrieved from past (OR, 1970–1980) and more recent revisions (NR, 2000–2010) of 331 forest compartments ranging between 0.35 and 53.1 ha. In the beech and spruce forest habitat types (coded 9130 and 9410 in Annex I of the Directive 92/43/EEC, respectively), we found an increase from OR to NR in the density of large trees (from 32 to 46/ha and from 31 to 50/ha, respectively for the two habitats), basal area (from 27.3 to 31.5 m2/ha and from 31 to 34.5 m2/ha), mean diameter (from 34.1 to 36.2 cm and from 33.9 to 36 cm) and Gini index (from 0.35 to 0.37 and from 0.33 to 0.36). Pursuant to the Directive 92/43/EEC, the conservation status of these two habitat types should be taken as “favorable” with regards to the criterion related to the habitats’ specific structure and functions that are necessary for its long-term maintenance. We conclude that forest management plans provide a great portion of the information needed for assessing and monitoring the conservation status of forest habitat types in the Natura 2000 framework
Modeling the influence of alternative forest management scenarios on wood production and carbon storage: A case study in the Mediterranean region
Forest ecosystems are fundamental for the terrestrial biosphere as they deliver multiple essential ecosystem services (ES). In environmental management, understanding ES distribution and interactions and assessing the economic value of forest ES represent future challenges. In this study, we developed a spatially explicit method based on a multi-scale approach (MiMoSe-Multiscale Mapping of ecosystem services) to assess the current and future potential of a given forest area to provide ES. To do this we modified and improved the InVEST model in order to adapt input data and simulations to the context of Mediterranean forest ecosystems. Specifically, we integrated a GIS-based model, scenario model, and economic valuation to investigate two ES (wood production and carbon sequestration) and their trade-offs in a test area located in Molise region (Central Italy). Spatial information and trade-off analyses were used to assess the influence of alternative forest management scenarios on investigated services. Scenario A was designed to describe the current Business as Usual approach. Two alternative scenarios were designed to describe management approaches oriented towards nature protection (scenario B) or wood production (scenario C) and compared to scenario A. Management scenarios were simulated at the scale of forest management units over a 20-year time period. Our results show that forest management influenced ES provision and associated benefits at the regional scale. In the test area, the Total Ecosystem Services Value of the investigated ES increases 85% in scenario B and decreases 82% in scenario C, when compared to scenario A. Our study contributes to the ongoing debate about trade-offs and synergies between carbon sequestration and wood production benefits associated with socio-ecological systems. The MiMoSe approach can be replicated in other contexts with similar characteristics, thus providing a useful basis for the projection of benefits from forest ecosystems over the futureL'articolo è disponibile sul sito dell'editore www.elsevier.com/locate/envre
