Lo scopo del presente lavoro è uno studio di fattibilità per la riconversione “Oxy-fuel” di una caldaia da 660 MWe alimentata a carbone, così da ottenere gas di scarico composti quasi esclusivamente da CO2 ed eliminare le problematiche della cattura post-combustione della anidride carbonica stessa. A questo scopo è stato sviluppato un modello di simulazione di una caldaia supercritica ENEL usando il software GateCycle®. Il modello è stato testato in condizioni di progetto, confrontando i risultati con i dati reali di impianto. Successivamente sono state eseguite delle simulazioni in condizioni di off-design, usando O2 puro e ricircolando i gas di scarico ricchi in CO2. In particolare sono state simulate quattro configurazioni di impianto, sia dal punto di vista delle performance che della complessità realizzativa. I risultati ottenuti sono interessanti, soprattutto per quanto riguarda le influenze quantitative dei parametri di impianto e delle configurazioni analizzate sulle performance della caldaia.

Ethanol greatly modifies synaptic function and it affects the reinnervation time course. In order to better clarify the effects of ethanol on nerve regeneration, we have observed the recovery of algesthesia and reflex activity in the rat during the treatment with ethanol. For this purpose the posterior leg of Sprague Dawley rats was denervated by crushing the sciatic nerve and the recovery of algesthesia and reflex activity was tested at the level of the metatarsus-falanx articulation of the homolateral paw. During the reinnervation period, the animals were treated daily with ethanol 3 g/Kg of body weight. The recovery of algesthesia and reflex activity comes about in a medio-lateral direction and proceeds linearly. It is completed on the 25th day after the denervation. Ethanol does not cause changes in the time course of algesthesia recovery, however it does cause a slight delay in the recovery of the reflex activity.

The moral evaluation of actions that disregard climate change, in individual as well as public ethics, is complex. A clear moral judgment itself is difficult to reach in both contexts, as we are far from paradigm moral cases where specific people provoke harm to easily identifiable others. However, for people to seriously engage in climate change mitigation, it has to be clear why it is wrong not to do so. There is therefore a need to frame moral responsibility for anti-environmen-tal behavior using language and concepts that are understandable to a broad public. This paper will argue that the concept of selfishness, properly construed, is the most appropriate tool for describing and morally evaluating human behavior that disregards climate change. A specific consequentialist definition of selfishness will be provided to this purpose. Some objections to framing the environmental decision in this way will be raised in public as well as individual ethics. In the public sphere, moral deliberations are complicated by the conflict between the rights of the present generation and those of future ones. In individual ethics, the inconsequentiality of individual emissions calls into question the very existence of a moral imperative to act pro-envi-ronmentally. The paper will thus investigate the grounds on which we can hold accountable pol-icy makers who refuse to take action on climate change, focusing on the concept of future dis-counting. With regard to the individual dimension, a proposal will be advanced on the basis of a non-superfluous causal contribution to collective-impact cases. In both contexts, the paper will eventually argue that anti-environmental actions can be defined as selfish according to the defini-tion provided.

La necessità della diversificazione delle fonti energetiche, unita agli impegni sul contenimento dei consumi energetici e sulla riduzione delle emissioni di gas serra, pone la fonte solare nella condizione di avere un ruolo incisivo nel panorama energetico italiano. Tra le tecnologie disponibili per lo sfruttamento della fonte solare per la produzione di energia, il solare termodinamico (Concentrating Solar Power – CSP) consente di produrre calore ad alta temperatura mediante sistemi solari a concentrazione. Con riferimento ad un impianto da 100 kWe costituito da un campo solare di tipo Solar Trough e da un gruppo di potenza basato su ciclo Rankine a fluidi organici, il cui prototipo verrà realizzato nell’ambito del progetto SOLAR, il presente studio si prefigge di effettuare una previsione della produzione di energia elettrica e di calore. Inoltre, si analizza la possibilità di realizzare il raffrescamento estivo mediante macchine frigorifere ad assorbimento valutando il risparmio energetico associato.

La situazione generalizzata di recessione economica e finanziaria, che dal 2008 ha scosso buona parte delle nazioni industrializzate, ha prodotto effetti significativi sulla vita quotidiana degli Italiani. In particolare, nel nostro paese sono cresciute, in quanto efficaci strategie di fronteggiamento della crisi, esperienze di disintermediazione della filiera (come, per esempio, i gruppi d’acquisto solidale, i mercati agricoli, gli affitti peer-to-peer, ecc.), di sharing (sotto forma di condivisione di mezzi di trasporti, di vacanze, di turismo esperienziale, ecc.) e di autoproduzione di oggetti, alimenti, vestiti, ecc. Tali pratiche, in realtà molto diffuse anche in passato in momenti di forti regressioni come per esempio negli anni Trenta o dopo lo shock petrolifero del 1973, appaiono oggi connotate da una maggiore consapevolezza. In altre parole, la disintermediazione della filiera, la condivisione e l’autoproduzione tendono non solo a mantenere livelli di vita e di benessere adeguati ma promuovono nuove forme di consumi, di organizzazione del lavoro e di partecipazione civile. La ricerca presentata in questo volume, frutto di un’indagine qualitativa condotta da un’equipe di sociologi dell’Università Cattolica del Sacro Cuore di Milano, ha esplorato le strategie quotidiane con cui individui e gruppi perseguono livelli soddisfacenti di benessere e di qualità della vita, coniugando pratiche “antiche” con i nuovi strumenti digitali e tecnologici. Tali pratiche sembrano, inoltre, prefigurare un futuro diverso, orientato a un uso più consapevole e sostenibile delle risorse, dei capitali umani, degli spazi, creando e diffondendo nuovi valori e inedite forme di partecipazione civile.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Doctoral thesis 2011 ItalyPublisher:Università degli studi della Tuscia - Viterbo Authors: Mancini, Marco <AGR/05>;Il destino delle foreste è legato in modo imprescindibile da come esse saranno in grado di rispondere al cambiamento climatico in atto. Non a caso, quindi, questo è un tema che negli ultimi anni ha ricevuto e sta ricevendo molte attenzioni da parte del mondo scientifico. Sebbene le foreste abbiano risposto al cambiamento climatico per tutta la loro storia evolutiva, una forte preoccupazione per gli ecosistemi forestali è data dalla rapidità del cambiamento. Esso avrà un forte impatto sulle utilizzazioni del territorio, sulla salute e sulla vitalità delle foreste, nonché sulla fornitura sostenibile di beni e servizi per la popolazione. Resta da chiarire quale sarà la risposta delle foreste ai cambiamenti climatici in atto, ed in particolare all’aumento di CO2 atmosferica e di temperatura nonché alle modifiche del regime idrico. Secondo quanto previsto dagli scenari dell’IPCC, il surriscaldamento climatico in atto tenderà a spostare verso latitudini maggiori e ad altitudini più elevate gli ambienti tipici dell’area mediterranea. A ciò vanno aggiunti, il rapido cambiamento dell’uso del suolo, la frammentazione degli habitat, lo sfruttamento delle risorse ambientali e la mancanza di un’adeguata pianificazione delle azioni antropiche, quali fattori che maggiormente degradano questi ambienti. L’importanza degli ecosistemi forestali nel mitigare gli effetti dei cambiamenti globali, mediante la fissazione e lo stoccaggio di grandi quantità di carbonio, è ormai ampiamente riconosciuta. Al fine di predire la produttività forestale a larga scala occorre disporre di un modello affidabile che richieda in ingresso pochi parametri di facile misurabilità. L’obiettivo del lavoro, quindi, è stato quello di predire per tre specie che caratterizzano il panorama forestale italiano: Fagus sylvatica, Quercus cerris e Quercus ilex, la magnitudine e l’impatto del cambiamento climatico sulla Produttività Primaria Netta (NPP), associata alla distribuzione potenziale attuale e futura delle specie, in funzione di scenari climatici. Attraverso l’utilizzo del modello semi-empirico Mo.C.A. è stato possibile stimare e spazializzare su tutto il territorio italiano, mediante l’uso di un GIS, gli output di NPP. Tale studio ha considerato sia il clima attuale secondo il trentennio di riferimento 1961-1990 stabilito dal WMO (World Metorological Organization), che due finestre temporali differenti, quali quella del 2031-2060 e quella del 2071-2100, secondo due scenari climatici realizzati dall’Hadley Centre: il B1 e l’A1Fi. Per avere una maggiore accuratezza nelle stime, gli output sono stati validati mettendoli a confronto con dati misurati attraverso la tecnica dell’eddy covariance, delle stazioni di misura presenti in popolamenti forestali uguali a quelli studiati. Inoltre, tale approccio ha consentito di dedurre alcuni aspetti relativi all’efficienza nell’utilizzo della risorsa idrica in relazione ad un gradiente latitudinale Sud-Nord e ai due diversi scenari climatici, grazie all’uso dell’indice WUE (Water Use Efficiency). Entrambi questi aspetti saranno utili per la definizione di protocolli e linee guida atti al mantenimento degli attuali popolamenti forestali e alla mitigazione/minimizzazione degli effetti del cambiamento climatico. The future of forests is bound to be so essential as they will be able to respond to climate change in progress. Not surprisingly, this is an issue that in recent years has received and is receiving much attention from the scientific world. Although forests have responded to climate change during their evolutionary history, a strong concern for forest ecosystems is given by the rapidity of change. It will have a strong impact on land use, health and vitality of forests and the sustainable provision of goods and services for the population. It remains unclear which will be the response of forests to climate changes, particularly the increase in atmospheric CO2 and temperature as well as changes of water regime. According to the IPCC scenarios, the ongoing climate warming will tend to move toward higher latitudes and altitude the typical Mediterranean environments. In addition, we have to consider the rapid change of land use, habitat fragmentation, exploitation of natural resources and the lack of proper planning of human actions, as factors that further degrade these environments. It is now widely accepted the importance of forest ecosystems in mitigating the effects of global change, through the establishment and the storage of large quantities of carbon. In order to predict forest productivity in a large scale we must have a reliable model that requires few input parameters easily measurable. The aim of this study was to predict for three species that characterize the Italian forest landscape: Fagus sylvatica, Quercus cerris and Quercus ilex, the magnitude and impact of climate change on net primary production (NPP), associated with current and future potential distribution of species, according to climatic scenarios. It has been possible to estimate, through the use of semi-empirical model Mo.C.A, and spatialise throughout the Italian territory, using a GIS, the outputs of NPP. The study considered both the current climate over the period 1961-1990 established by the WMO (World Metorological Organization), and the potential one of other two temporal ranges, such as that of 2031-2060 and 2071-2100, according to two climatic scenarios produced by Hadley Centre: the B1 and the A1Fi. To get more accuracy in the estimates, the outputs have been validated by comparing them with data calculated in forest measuring stations located in areas with the same studied species, by the eddy covariance technique. Furthermore this approach has been useful to deduce some aspects of efficiency in the use of water resources in relation to a latitudinal gradient from south to north and two different climate scenarios, through the use of WUE index. Both these aspects will be necessary to define protocols and guidelines aimed to maintain the existing actual forest stands and to mitigate / minimize the climate change effects.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Doctoral thesis 2011 ItalyPublisher:Università degli studi della Tuscia - Viterbo Dottorato di ricerca in Ecologia forestale ; L’accelerazione dei cambiamenti climatici, unita alle previsioni di scarsità dei combustibili fossili, ha portato, tanto a livello internazionale, quanto nella dimensione locale, a dare un forte impulso alla produzione ed al consumo delle fonti energetiche rinnovabili. La biomassa rappresenta la prima fonte di energia rinnovabile in Europa, e la seconda in Italia. Importanti aspettative sono legate all’impiego energetico delle biomasse di origine agro-forestale in virtù dei potenziali vantaggi che ne derivano, non solo da un punto di vista ambientale ma anche per le positive ricadute sul tessuto socio-economico locale. Al fine di garantirne un uso razionale delle biomasse e permettere di programmare azioni concrete volte al loro sfruttamento in armonia con il territorio, si rendono fondamentali studi e ricerche puntali che tengano conto delle peculiari caratteristiche locali. Alla luce delle considerazioni fatte, l’obiettivo di questo lavoro è quello di individuare e quantificare le principali risorse presenti nel territorio del Parco Naturale Regionale di Bracciano-Martignano. Lo studio si rivolge a un’area protetta proprio in virtù delle finalità stesse per cui il Parco è stato istituito: garantire e incentivare lo sviluppo sociale e economico locale attraverso la promozione di attività compatibili in grado comunque di garantire la conservazione e la valorizzazione del territorio (L.R. n° 36 del 25/11/1999). In particolare l’attenzione è stata rivolta a quelle biomasse di natura residuale che al momento non presentano altri impieghi e che allo stesso tempo sia tecnicamente ed economicamente conveniente utilizzare per produrre energia. Quindi è stata formulata una stima di tutti gli scarti di matrice lignocellulosica (paglie, steli, potature, cimali ecc.) che derivano dalla coltivazione di piante erbacee ed arboree e dalle utilizzazioni forestali. Tale risultato è stato ottenuto attraverso la rivisitazione e l’aggiornamento della metodologia AIGR-ENEA usata negli anni ’90 per la stima a livello nazionale con dettaglio provinciale delle biomasse solide combustibili. Nel corso del lavoro sono stati realizzati dei campionamenti e sopralluoghi sul territorio allo scopo di valutare l’effettiva attendibilità dei parametri di stima proposti nella metodologia di base e valutare il grado di rappresentazione delle reali condizioni presenti sul territorio. A conclusione del lavoro di stima si è cercato di valutare e dimensionare un possibile impianto alimentato da biomasse locali e di fornire indicazioni il migliore utilizzo energetico dei sottoprodotti. Parallelamente alla stima delle biomasse locali per uso energetico, è stata condotta una prima analisi circa la produzione di biomassa nelle aree forestali del Parco ed il relativo stock di carbonio. La quantificazione del carbonio immagazzinato nei castagneti del Parco è stata realizzata grazie all’impiego di un modulo implementato nell’ambito del progetto KEI-EXTENSION e basato sul modello previsionale 3-PG. Le stime pur se preliminari, introdotte in questo lavoro, forniscono importanti informazioni sulla base delle quali sarà possibile proseguire la ricerca e ottenere valori di stock e previsioni di accumulo di carbonio nei vari comparti forestali dell’area protetta. ; In few years the production and consumption of renewable energy sources is strongly increased at international level and this is related to the policies to fight climate changes and promote fossil fuels substitution. Biomass is the primary source of renewable energy in Europe, and the second one in Italy. Most expectations to agro-forestry biomass as energy sources are connected to their environmental benefits and the potential positive impact in the local social-economic development. In order to promote a rationale use of locally available biomass, there is a strong need to promote studies and researches about specific areas taking into account their physical and socioeconomic characteristics. The aim of this study is to identify and assess the agro-forestry resources of the Regional Natural Park of Bracciano-Martignano territory. The study and its reasults have an important implication on the Natural Park goals by indirectly helping the promotion of the economic and social development of the Park, compatibly with the conservation of the territory (LR n. 36 of 11.25.1999). Therefore, this study would like to provide a clear assessment of the biomass potential from the agro-forestry sectors that can be exploited to produce energy. In particular, it has been paid attention to the biomass which currently do not have any other technically and economically more convenient use: residues from woodland and agricultural residues (pruning, straw). The AIGR-ENEA methodology, reviewed and updated, has been used to estimate local gross and net biomass potential. To improve results reliability local surveys and inspections on site have been carried out with the aim to define local parameters for residues calculation. Globally in the park area we estimated that, on an average year, we could exploit about 17 kilotons of biomass (dry matter) and that a local thermal use seems to be the best option. This study could help to raise the awareness of the public opinion and decision makers about the possibilities offered by the agro-forestry sector as a source of biomass for energy use and provide a better knowledge of biomass availability to support local policies to enhance local development. Furthermore, in this study it was performed a preliminary analysis on total forest biomass and the carbon stocks. Indeed, it was possible to make a first step towards the quantification of biomass in the chestnut forest of the park by using a module implemented within the project KEI-EXTENSION, based on model 3-PG. The first stage of the biomass estimation, introduced in this study provide important information on the basis of which it could be possible to evaluate current and future carbon stocks and better evaluate the exploitation level of local forests for energy uses that do not compromise the carbon stock.

Lo scopo del presente lavoro è uno studio di fattibilità per la riconversione “Oxy-fuel” di una caldaia da 660 MWe alimentata a carbone, così da ottenere gas di scarico composti quasi esclusivamente da CO2 ed eliminare le problematiche della cattura post-combustione della anidride carbonica stessa. A questo scopo è stato sviluppato un modello di simulazione di una caldaia supercritica ENEL usando il software GateCycle®. Il modello è stato testato in condizioni di progetto, confrontando i risultati con i dati reali di impianto. Successivamente sono state eseguite delle simulazioni in condizioni di off-design, usando O2 puro e ricircolando i gas di scarico ricchi in CO2. In particolare sono state simulate quattro configurazioni di impianto, sia dal punto di vista delle performance che della complessità realizzativa. I risultati ottenuti sono interessanti, soprattutto per quanto riguarda le influenze quantitative dei parametri di impianto e delle configurazioni analizzate sulle performance della caldaia.

Ethanol greatly modifies synaptic function and it affects the reinnervation time course. In order to better clarify the effects of ethanol on nerve regeneration, we have observed the recovery of algesthesia and reflex activity in the rat during the treatment with ethanol. For this purpose the posterior leg of Sprague Dawley rats was denervated by crushing the sciatic nerve and the recovery of algesthesia and reflex activity was tested at the level of the metatarsus-falanx articulation of the homolateral paw. During the reinnervation period, the animals were treated daily with ethanol 3 g/Kg of body weight. The recovery of algesthesia and reflex activity comes about in a medio-lateral direction and proceeds linearly. It is completed on the 25th day after the denervation. Ethanol does not cause changes in the time course of algesthesia recovery, however it does cause a slight delay in the recovery of the reflex activity.

The moral evaluation of actions that disregard climate change, in individual as well as public ethics, is complex. A clear moral judgment itself is difficult to reach in both contexts, as we are far from paradigm moral cases where specific people provoke harm to easily identifiable others. However, for people to seriously engage in climate change mitigation, it has to be clear why it is wrong not to do so. There is therefore a need to frame moral responsibility for anti-environmen-tal behavior using language and concepts that are understandable to a broad public. This paper will argue that the concept of selfishness, properly construed, is the most appropriate tool for describing and morally evaluating human behavior that disregards climate change. A specific consequentialist definition of selfishness will be provided to this purpose. Some objections to framing the environmental decision in this way will be raised in public as well as individual ethics. In the public sphere, moral deliberations are complicated by the conflict between the rights of the present generation and those of future ones. In individual ethics, the inconsequentiality of individual emissions calls into question the very existence of a moral imperative to act pro-envi-ronmentally. The paper will thus investigate the grounds on which we can hold accountable pol-icy makers who refuse to take action on climate change, focusing on the concept of future dis-counting. With regard to the individual dimension, a proposal will be advanced on the basis of a non-superfluous causal contribution to collective-impact cases. In both contexts, the paper will eventually argue that anti-environmental actions can be defined as selfish according to the defini-tion provided.

La necessità della diversificazione delle fonti energetiche, unita agli impegni sul contenimento dei consumi energetici e sulla riduzione delle emissioni di gas serra, pone la fonte solare nella condizione di avere un ruolo incisivo nel panorama energetico italiano. Tra le tecnologie disponibili per lo sfruttamento della fonte solare per la produzione di energia, il solare termodinamico (Concentrating Solar Power – CSP) consente di produrre calore ad alta temperatura mediante sistemi solari a concentrazione. Con riferimento ad un impianto da 100 kWe costituito da un campo solare di tipo Solar Trough e da un gruppo di potenza basato su ciclo Rankine a fluidi organici, il cui prototipo verrà realizzato nell’ambito del progetto SOLAR, il presente studio si prefigge di effettuare una previsione della produzione di energia elettrica e di calore. Inoltre, si analizza la possibilità di realizzare il raffrescamento estivo mediante macchine frigorifere ad assorbimento valutando il risparmio energetico associato.

La situazione generalizzata di recessione economica e finanziaria, che dal 2008 ha scosso buona parte delle nazioni industrializzate, ha prodotto effetti significativi sulla vita quotidiana degli Italiani. In particolare, nel nostro paese sono cresciute, in quanto efficaci strategie di fronteggiamento della crisi, esperienze di disintermediazione della filiera (come, per esempio, i gruppi d’acquisto solidale, i mercati agricoli, gli affitti peer-to-peer, ecc.), di sharing (sotto forma di condivisione di mezzi di trasporti, di vacanze, di turismo esperienziale, ecc.) e di autoproduzione di oggetti, alimenti, vestiti, ecc. Tali pratiche, in realtà molto diffuse anche in passato in momenti di forti regressioni come per esempio negli anni Trenta o dopo lo shock petrolifero del 1973, appaiono oggi connotate da una maggiore consapevolezza. In altre parole, la disintermediazione della filiera, la condivisione e l’autoproduzione tendono non solo a mantenere livelli di vita e di benessere adeguati ma promuovono nuove forme di consumi, di organizzazione del lavoro e di partecipazione civile. La ricerca presentata in questo volume, frutto di un’indagine qualitativa condotta da un’equipe di sociologi dell’Università Cattolica del Sacro Cuore di Milano, ha esplorato le strategie quotidiane con cui individui e gruppi perseguono livelli soddisfacenti di benessere e di qualità della vita, coniugando pratiche “antiche” con i nuovi strumenti digitali e tecnologici. Tali pratiche sembrano, inoltre, prefigurare un futuro diverso, orientato a un uso più consapevole e sostenibile delle risorse, dei capitali umani, degli spazi, creando e diffondendo nuovi valori e inedite forme di partecipazione civile.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Doctoral thesis 2011 ItalyPublisher:Università degli studi della Tuscia - Viterbo Authors: Mancini, Marco <AGR/05>;Il destino delle foreste è legato in modo imprescindibile da come esse saranno in grado di rispondere al cambiamento climatico in atto. Non a caso, quindi, questo è un tema che negli ultimi anni ha ricevuto e sta ricevendo molte attenzioni da parte del mondo scientifico. Sebbene le foreste abbiano risposto al cambiamento climatico per tutta la loro storia evolutiva, una forte preoccupazione per gli ecosistemi forestali è data dalla rapidità del cambiamento. Esso avrà un forte impatto sulle utilizzazioni del territorio, sulla salute e sulla vitalità delle foreste, nonché sulla fornitura sostenibile di beni e servizi per la popolazione. Resta da chiarire quale sarà la risposta delle foreste ai cambiamenti climatici in atto, ed in particolare all’aumento di CO2 atmosferica e di temperatura nonché alle modifiche del regime idrico. Secondo quanto previsto dagli scenari dell’IPCC, il surriscaldamento climatico in atto tenderà a spostare verso latitudini maggiori e ad altitudini più elevate gli ambienti tipici dell’area mediterranea. A ciò vanno aggiunti, il rapido cambiamento dell’uso del suolo, la frammentazione degli habitat, lo sfruttamento delle risorse ambientali e la mancanza di un’adeguata pianificazione delle azioni antropiche, quali fattori che maggiormente degradano questi ambienti. L’importanza degli ecosistemi forestali nel mitigare gli effetti dei cambiamenti globali, mediante la fissazione e lo stoccaggio di grandi quantità di carbonio, è ormai ampiamente riconosciuta. Al fine di predire la produttività forestale a larga scala occorre disporre di un modello affidabile che richieda in ingresso pochi parametri di facile misurabilità. L’obiettivo del lavoro, quindi, è stato quello di predire per tre specie che caratterizzano il panorama forestale italiano: Fagus sylvatica, Quercus cerris e Quercus ilex, la magnitudine e l’impatto del cambiamento climatico sulla Produttività Primaria Netta (NPP), associata alla distribuzione potenziale attuale e futura delle specie, in funzione di scenari climatici. Attraverso l’utilizzo del modello semi-empirico Mo.C.A. è stato possibile stimare e spazializzare su tutto il territorio italiano, mediante l’uso di un GIS, gli output di NPP. Tale studio ha considerato sia il clima attuale secondo il trentennio di riferimento 1961-1990 stabilito dal WMO (World Metorological Organization), che due finestre temporali differenti, quali quella del 2031-2060 e quella del 2071-2100, secondo due scenari climatici realizzati dall’Hadley Centre: il B1 e l’A1Fi. Per avere una maggiore accuratezza nelle stime, gli output sono stati validati mettendoli a confronto con dati misurati attraverso la tecnica dell’eddy covariance, delle stazioni di misura presenti in popolamenti forestali uguali a quelli studiati. Inoltre, tale approccio ha consentito di dedurre alcuni aspetti relativi all’efficienza nell’utilizzo della risorsa idrica in relazione ad un gradiente latitudinale Sud-Nord e ai due diversi scenari climatici, grazie all’uso dell’indice WUE (Water Use Efficiency). Entrambi questi aspetti saranno utili per la definizione di protocolli e linee guida atti al mantenimento degli attuali popolamenti forestali e alla mitigazione/minimizzazione degli effetti del cambiamento climatico. The future of forests is bound to be so essential as they will be able to respond to climate change in progress. Not surprisingly, this is an issue that in recent years has received and is receiving much attention from the scientific world. Although forests have responded to climate change during their evolutionary history, a strong concern for forest ecosystems is given by the rapidity of change. It will have a strong impact on land use, health and vitality of forests and the sustainable provision of goods and services for the population. It remains unclear which will be the response of forests to climate changes, particularly the increase in atmospheric CO2 and temperature as well as changes of water regime. According to the IPCC scenarios, the ongoing climate warming will tend to move toward higher latitudes and altitude the typical Mediterranean environments. In addition, we have to consider the rapid change of land use, habitat fragmentation, exploitation of natural resources and the lack of proper planning of human actions, as factors that further degrade these environments. It is now widely accepted the importance of forest ecosystems in mitigating the effects of global change, through the establishment and the storage of large quantities of carbon. In order to predict forest productivity in a large scale we must have a reliable model that requires few input parameters easily measurable. The aim of this study was to predict for three species that characterize the Italian forest landscape: Fagus sylvatica, Quercus cerris and Quercus ilex, the magnitude and impact of climate change on net primary production (NPP), associated with current and future potential distribution of species, according to climatic scenarios. It has been possible to estimate, through the use of semi-empirical model Mo.C.A, and spatialise throughout the Italian territory, using a GIS, the outputs of NPP. The study considered both the current climate over the period 1961-1990 established by the WMO (World Metorological Organization), and the potential one of other two temporal ranges, such as that of 2031-2060 and 2071-2100, according to two climatic scenarios produced by Hadley Centre: the B1 and the A1Fi. To get more accuracy in the estimates, the outputs have been validated by comparing them with data calculated in forest measuring stations located in areas with the same studied species, by the eddy covariance technique. Furthermore this approach has been useful to deduce some aspects of efficiency in the use of water resources in relation to a latitudinal gradient from south to north and two different climate scenarios, through the use of WUE index. Both these aspects will be necessary to define protocols and guidelines aimed to maintain the existing actual forest stands and to mitigate / minimize the climate change effects.

La biomassa rappresenta la prima fonte di energia rinnovabile in Europa, e la seconda in Italia. Importanti aspettative sono legate all’impiego energetico delle biomasse di origine agro-forestale in virtù dei potenziali vantaggi che ne derivano, non solo da un punto di vista ambientale ma anche per le positive ricadute sul tessuto socio-economico locale. Al fine di garantirne un uso razionale delle biomasse e permettere di programmare azioni concrete volte al loro sfruttamento in armonia con il territorio, si rendono fondamentali studi e ricerche puntali che tengano conto delle peculiari caratteristiche locali. Alla luce delle considerazioni fatte, l’obiettivo di questo lavoro è quello di individuare e quantificare le principali risorse presenti nel territorio del Parco Naturale Regionale di Bracciano-Martignano. Lo studio si rivolge a un’area protetta proprio in virtù delle finalità stesse per cui il Parco è stato istituito: garantire e incentivare lo sviluppo sociale e economico locale attraverso la promozione di attività compatibili in grado comunque di garantire la conservazione e la valorizzazione del territorio (L.R. n° 36 del 25/11/1999). In particolare l’attenzione è stata rivolta a quelle biomasse di natura residuale che al momento non presentano altri impieghi e che allo stesso tempo sia tecnicamente ed economicamente conveniente utilizzare per produrre energia. Quindi è stata formulata una stima di tutti gli scarti di matrice lignocellulosica (paglie, steli, potature, cimali ecc.) che derivano dalla coltivazione di piante erbacee ed arboree e dalle utilizzazioni forestali. Tale risultato è stato ottenuto attraverso la rivisitazione e l’aggiornamento della metodologia AIGR-ENEA usata negli anni ’90 per la stima a livello nazionale con dettaglio provinciale delle biomasse solide combustibili. Nel corso del lavoro sono stati realizzati dei campionamenti e sopralluoghi sul territorio allo scopo di valutare l’effettiva attendibilità dei parametri di stima proposti nella metodologia di base e valutare il grado di rappresentazione delle reali condizioni presenti sul territorio. A conclusione del lavoro di stima si è cercato di valutare e dimensionare un possibile impianto alimentato da biomasse locali e di fornire indicazioni il migliore utilizzo energetico dei sottoprodotti. Parallelamente alla stima delle biomasse locali per uso energetico, è stata condotta una prima analisi circa la produzione di biomassa nelle aree forestali del Parco ed il relativo stock di carbonio. La quantificazione del carbonio immagazzinato nei castagneti del Parco è stata realizzata grazie all’impiego di un modulo implementato nell’ambito del progetto KEI-EXTENSION e basato sul modello previsionale 3-PG. Le stime pur se preliminari, introdotte in questo lavoro, forniscono importanti informazioni sulla base delle quali sarà possibile proseguire la ricerca e ottenere valori di stock e previsioni di accumulo di carbonio nei vari comparti forestali dell’area protetta. ; In few years the production and consumption of renewable energy sources is strongly increased at international level and this is related to the policies to fight climate changes and promote fossil fuels substitution. Biomass is the primary source of renewable energy in Europe, and the second one in Italy. Most expectations to agro-forestry biomass as energy sources are connected to their environmental benefits and the potential positive impact in the local social-economic development. In order to promote a rationale use of locally available biomass, there is a strong need to promote studies and researches about specific areas taking into account their physical and socioeconomic characteristics. The aim of this study is to identify and assess the agro-forestry resources of the Regional Natural Park of Bracciano-Martignano territory. The study and its reasults have an important implication on the Natural Park goals by indirectly helping the promotion of the economic and social development of the Park, compatibly with the conservation of the territory (LR n. 36 of 11.25.1999). Therefore, this study would like to provide a clear assessment of the biomass potential from the agro-forestry sectors that can be exploited to produce energy. In particular, it has been paid attention to the biomass which currently do not have any other technically and economically more convenient use: residues from woodland and agricultural residues (pruning, straw). The AIGR-ENEA methodology, reviewed and updated, has been used to estimate local gross and net biomass potential. To improve results reliability local surveys and inspections on site have been carried out with the aim to define local parameters for residues calculation. Globally in the park area we estimated that, on an average year, we could exploit about 17 kilotons of biomass (dry matter) and that a local thermal use seems to be the best option. This study could help to raise the awareness of the public opinion and decision makers about the possibilities offered by the agro-forestry sector as a source of biomass for energy use and provide a better knowledge of biomass availability to support local policies to enhance local development. Furthermore, in this study it was performed a preliminary analysis on total forest biomass and the carbon stocks. Indeed, it was possible to make a first step towards the quantification of biomass in the chestnut forest of the park by using a module implemented within the project KEI-EXTENSION, based on model 3-PG. The first stage of the biomass estimation, introduced in this study provide important information on the basis of which it could be possible to evaluate current and future carbon stocks and better evaluate the exploitation level of local forests for energy uses that do not compromise the carbon stock.
