Integrating risk management tools for regional forest planning: an interactive multiobjective value-at-risk approach
2018
In this paper, we present an approach employing multiobjective optimization to support decision making in forest management planning under risk. The primary objectives are biodiversity and timber cash flow, evaluated from two perspectives: the expected value and the value-at-risk (VaR). In addition, the risk level for both the timber cash flow and biodiversity values are included as objectives. With our approach, we highlight the trade-off between the expected value and the VaR, as well as between the VaRs of the two objectives of interest. We employ an interactive method in which a decision maker iteratively provides preference information to find the most preferred management plan and le…
Forest planning across Europe: the spatial scale, tools, and inter-sectoral integration in land-use planning
2014
New approaches to forest planning are needed to support the transition of European forests to sustainable management. The aim of this study is to review forest planning systems already in place throughout Europe by exploring a set of case-study countries reflecting the main silvicultural schools of Western Europe, including Belgium, Finland, France, Italy, Portugal, and Slovenia. A literature review and case-study data were used to assess the scale factors (vertical logic) as well as the relationships between forest planning and other environmental6 land-use planning sectors (horizontal logic). The influence of EU policy on the development of forest planning is also discussed. As assessed u…
Il piano di gestione dei boschi demaniali del Comune di Bivona (Provincia di Agrigento)
2014
L’area dei Monti Sicani costituisce uno dei comprensori in cui è stata realizzata la maggiore estensione di rimboschimenti di conifere della Sicilia occidentale, nell’ambito della politica di salvaguardia del territorio dal dissesto idrogeologico intrapresa dallo Stato e continuata dalla Regione. Lo stato qualitativo di queste formazioni è carente a causa di diverse ragioni: frequenti incendi, pascolo eccessivo, elevata frammentazione degli habitat naturali, mancanza di adeguati interventi selvicolturali. Da queste considerazioni emerge la necessità di conoscere e gestire più adeguatamente tali boschi attraverso la realizzazione di Piani di Gestione Forestale, strumento operativo-applicativ…
Using SMAA-2 method with dependent uncertainties for strategic forest planning
2006
Abstract Uncertainty included in forest variables is normally ignored in forest management planning. When the uncertainty is accounted for, it is typically assumed to be independently distributed for the criteria measurements of different alternatives. In forest management planning, the factors introducing the uncertainty can be classified into three main sources: the errors in the basic forestry data, the uncertainty of the (relative) future prices of timber, and the uncertainty in predicting the forest development. Due to the nature of these error sources, most of the involved uncertainties can be assumed to be positively correlated across the alternative management plans and/or criteria.…
Environmental Planning Inputs by the Forest Sector: The Scale Factor, the Connection Planning-Management and the Relations with other Planning Sector…
2011
In the twentieth-century Italy, as many other densely populated European countries, has been characterized by a progressive reduction of the forest cover, specially in the southern Mediterranean regions. Generally, the mountain areas developed a forest based economy, especially in north east Alps and in the Mediterranean Apennine inner mountains. Several distinctions must be taken into account, for example with regard to ownership of the woods. On the Alps, generally the forest are municipal, community or private properties. In the Mediterranean Apennines inner areas there are many wide state owned forest, followed by municipal properties, while the private property is, on average, less dif…
Climate variability in forest management planning: The LIFE AForClimate project.
2018
Previous research experiences have shown that climate variability can play a relevant role in forest planning and management within a climate change scenario. In forest planning and management, yield tables, site quality indices, age classes, and rates of growth are some of the most frequently used parameters and tools. However, these ‘traditional’ methods do not include the influence of climate variability on forest growth over time, although it is one of the main influencing factors in tree growth. Changes in climate determine changes in thermo-pluviometric regimes that often have a marked influence on forest growth trends. Forest biomass, resilience, and carbon sequestration may be damag…
STUDIO PROPEDEUTICO PER LA REDAZIONE DI UN PIANO DI GESTIONE FORESTALE DEL BOSCO TARDARA, SUGHERETA PURA DEL COMUNE DI TUSA (MESSINA)
2019
La Sicilia è la seconda regione d’Italia per estensione delle formazioni naturali a Quercus suber (L.).Sugherete più o meno degradate sono presenti in tutte le province, il cui stato qualitativo oggi risulta carente a causa dei frequenti incendi, pascolo eccessivo e mancanza di adeguate cure colturali, ma certamente tra tutte le cause la principale è l’assenza di pianificazione. Da questa premessa affiora la necessità di conoscere e governare in modo congruo la superficie boscata siciliana attraverso la redazione di Piani di Gestione Forestale, mirando al ripristino dell’efficienza, della funzionalità e, in particolar modo, della produzione sostenibile dei boschi a sughera. Con il presente …
La pianificazione ai fini della valorizzazione delle risorse legnose in Sicilia: un caso di studio su popolamenti di castagno dei Nebrodi
2019
In Sicily, forest planning still has too many gaps. This study proposes both to make a contribution to the current cognitive framework of the Nebrodi chestnut groves, and to draw up a management plan that is still lacking in order to identify forestry addresses and sustainable management necessary to maintain and defend these forest formations.
Improving Economic Management Decisions in Forestry with the SorSim Assortment Model
2020
The sustainable supply of timber is one of the most important forest ecosystem services and a decisive factor determining the long-term profitability of forest enterprises. If timber production is to be economically viable, there must always be a way to analyse forest stands and trees felled for exploitation with regard to the wood assortments they contain. Only then can the expected timber yields, achieved by various silvicultural strategies or actions and different sorting options, be quantified with sufficient accuracy. The SorSim assortment simulator was developed for forest practitioners and forest scientists in Switzerland to realistically simulate the sorting of individual trees and …
The MIMOSE Approach to Support Sustainable Forest Management Planning at Regional Scale in Mediterranean Contexts
2017
In recent decades, Mediterranean landscapes have been affected by human-induced drivers, such as land use and climate change. Forest ecosystems and landscapes have been particularly affected in mountainous regions due to limited management and stewardship, especially in remote areas. Therefore, there is a need to set up new strategies to enhance ecosystem services in forested areas which, in turn, will benefit local communities and economies. In this study, we implemented a new approach—Multiscale Mapping of Ecosystem Services (MIMOSE)—to assess ecosystem services in Mediterranean forests located in a mountainous region of Italy. We spatially assessed timber provision and carbon sequestrati…
