Stima spazialmente definita della produttività potenziale delle risorse agro-forestali per uso energetico: il caso di studio della regione Molise.
In questo lavoro sono riportati i risultati della stima della disponibilita di biomassa per uso energetico ottenibile dalle risorse agro-forestali a seguito dell'applicazione di criteri di sostenibilita. Le analisi sono state effettuate a due differenti scale geografiche: la prima a livello nazionale e la seconda a livello regionale, basata su strati informativi di maggior dettaglio, e con risultati aggregati a livello comunale. In entrambi i casi sono stati applicati dei vincoli alla produzione di biomassa strettamente connessi alle caratteristiche morfologiche, tecnico-strutturali e gestionali dell'area di studio e all'uso di criteri che garantiscono la sostenibilita della gestione delle risorse forestali basati sulla provvigione minimale
Integrated forest management to prevent wildfires under Mediterranean environments
This review presents a multidisciplinary framework for integrating the ecological, regulatory, procedural and technical
aspects of forest management for fi res prevention under Mediterranean environments. The aims are to: i) provide a foreground of
wildfi re scenario; ii) illustrate the theoretical background of forest fuel management; iii) describe the available fuel management techniques
and mechanical operations for fi re prevention in forest and wildland-urban interfaces, with exemplifi cation of case-studies; iv)allocate fi re prevention activities under the hierarchy of forest planning. The review is conceived as an outline commentary discussion targeted to professionals, technicians and government personnel involved in forestry and environmental management
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

Mapping and assessment of forest ecosystems and their services - Applications and guidance for decision making in the framework of MAES
The aim of this report is to illustrate by means of a series of case studies the implementation of mapping and assessment of forest ecosystem services in different contexts and geographical levels. Methodological aspects, data issues, approaches, limitations, gaps and further steps for improvement are analysed for providing good practices and decision making guidance. The EU initiative on Mapping and Assessment of the state of Ecosystems and their Services (MAES), with the support of all Member States, contributes to improve the knowledge on ecosystem services. MAES is one of the building-block initiatives supporting the EU Biodiversity Strategy to 2020.JRC.H.3-Forest Resources and Climat
Forest management scenarios to reduce the fire risk in chestnut coppices in the Mediterranean area
Chestnut coppices are among the formation most affected by fires in the Mediterranean environment. In the absence of cultivation treatments, the structure of the stands appears without vertical and horizontal interruptions in the canopy, with a considerable expansion of the fuel load. In this study, we showed the importance of silvicultural interventions on the mitigation of the fire in the chestnut coppices of southern Italy. In the study sites, we estimated the pyrological potential in terms of heat energy produced per surface unit and the variation in the critical surface intensity. Following silvicultural interventions, the reduction of heat energy is between 12.5 and 50%, and the extinguishing water saving are between 270 and 1,157 Mg·ha-1. The reduction of the probability of the passage of the surface fire to a crown fire can be up to 375%. With the same environmental conditions and dendro-structural characteristics, most effective interventions were observed for rotation cycles of 30 years, compared to shorter rotation cycles. This study showed the importance that silvicultural interventions, such as cleaning and bottom-up thinning, have at both the stand and territorial level on fire risk mitigation
Warming-related growth responses at the southern limit distribution of mountain pine ( Pinus mugo Turra subsp. mugo )
International audienceQuestions: Could mountain pine (Pinus mugo Turra subsp. mugo) located above the timberline and at the southern limit of its potential geographic distribution be a promising species to monitor climatic change in specific environments such as the Mediterranean mountains? Does mountain pine krummholz upward expansion result from current climate change? Has the relationship between climate and tree ring growth of mountain pine changed? To what extent does climatic variability affect tree ring growth? Could mountain pine upward expansion contribute to loss of biodiversity in the undisturbed tree line ecotone on the Majella massif
