Air Quality Integrated Assessment. A European Perspective
No full textThis book reports on the results of an extended survey conducted across Europe within the framework of the APPRAISAL FP7 project to determine the extent to which an integrated assessment approach to air quality is being adopted, on the one hand, by regional and local authorities to develop air quality plans and, on the other, by researchers. Following a detailed analysis of the role and structure of the components of an integrated assessment study, the results of the survey are considered from a variety of perspectives. Above all, the book discusses the new light the survey sheds on emission abatement policies and measures planned at regional and local scales, and on their synergies/trade-offs with measures implemented at the national scale. Detailed consideration is given to the currently available modeling methodologies for identifying emission sources, assessing the effectiveness of emission reduction measures, and evaluating the impacts of emission abatement measures on human health. Current strengths and weaknesses revealed by the survey are explored, and the application of an integrated assessment tool in two case studies (in Brussels and Porto) is discussed. The book will appeal to all those interested in the use of integrated assessment in connection with the sources, effects and control of air pollution
Il ruolo delle tecnologie dell’informazione e della comunicazione nelle emergenze
No full textAccanto alle tradizionali tecniche di previsione delle variabili ambientali significative, le tecnologie
dell’informazione e della comunicazione (ICT) giocano oggi un ruolo sempre più rilevante nel
preparare, gestire e superare le emergenze (Asimakopoulou e Bessis, 2010). In queste situazioni
infatti non è solo l’aspetto fisico del fenomeno ad essere rilevante, ma soprattutto il suo impatto
sociale, cioè come la società si prepara, vive e successivamente recupera le situazioni critiche ed
affronta le scelte economiche ad esse legate. Come è noto infatti, se i danni economici delle piene
fluviali sono aumentati fortemente in tutto il mondo nel corso degli ultimi anni, non è solo per
l’intensificarsi dei fenomeni estremi, quanto per il maggior valore delle opere e la maggior quantità
di popolazione che vive in aree a rischio di esondazioni
Modeling the role of forests in a regional carbon mitigation plan
No full textBiomass from the forest sector can be an important source of renewable energy and can contribute to climate change mitigation and bioenergy development. However, the removal of biomass from forests has significant impacts on the forest ecosystem. For instance, it modifies soil litter which is particularly important to preserve soil characteristics and to sustain a diversity of organisms. Our aim is to analyze alternatives of sustainable forest management and compare how they perform in terms of carbon savings in order to assess the role of the sector in a regional emission reduction plan. The analysis is performed applying CO2FIX, a well-known carbon accounting model to the forests of the Italian region of Emilia-Romagna. The behavior of the most important forest macro-categories is investigated under common management alternatives: no harvest activities, maintenance of a constant stock, different rotation lengths, and maximization of harvested biomass. We evaluate their impact at landscape level on the regional carbon budget, thus estimating the maximum potential contribution from the forest sector
