Among the production sectors, agriculture is the most significantly influenced by the effect of climate change. This study is aimed at understanding and measuring the changes that occur in agricultural systems due to climate, and at determining how climate change can affect both agricultural productivity and the environmental impacts of agricultural systems, by focusing a case study on the Trasimeno Lake (region of Umbria, Italy). The analysis was performed using the CropSyst software package. CropSyst is a multi-year, multicrop, daily time step crop growth simulation model with the possibility of connection with GIS (Geographic Information System) software. The specific typology of climate change that was simulated was the doubling of the amount of CO2 in the atmosphere during a time interval of 100 years (from year 2000 to 2100), according to the hypothesis of the CCM3 model (Govindasamy et al., 2003). The results of our simulation have shown an increase of plant productivity (connected with yield and biomass production) and an invariable situation concerning the indicators of stress by nitrogen, water and temperature. With reference to the environmental situation, our results have shown a general increase of nitrogen lisciviation, as a consequence of the increase of mineralisation, with potential effects on the soil fertility loss, and a decrease of runoff and deep percolation. The erosion indicator did not vary in a significant way. Our CropSyst - GIS system developed for this study has been useful both for the evaluation of the existing data, and for the simulation of future data.

The model is applied to the Umbrian territory, for analyzing the dynamics of the vegetation. The applications proposed are two: the former is on the whole regional vegetation, while the latter considers just one specific agrarian typology, the olive orchards. The analysis of anomalies is possible thanks to a database of data collected since January 1st 2001. The comparison between NDVIi and NDVIaverage (the latter taken from the database) allows to identify areas, and the corresponding habitats, which show significant anomalies. Information obtained from such an analysis can be used for constructing synthetic indicators, representing the response of vegetation to climate var...

Although the main aim of the network is to protect the habitat, it also considers the economic, social and cultural needs of the people involved. Moreover, Natura 2000 is recognised for its provision of several ecosystem services and it has, therefore, put management plans in place for these areas. This paper assessed residents' preferences for provisioning, regulating and supporting ecosystem services provided by the Region of Umbria network. The Willingness To Pay for improving such ecosystems services is also estimated and used to evaluate the overall benefit provided by the management of the network in two hypothetical scenarios. The average benefit per hectare per year for achieving the less demanding scenario is €75, whereas an additional €64 is required for the more challenging policy scenario. The estimated benefit is greater than the current expenditure for the regional management of the Natura 2000 network. 1. Introduction Natura 2000 Network (N2K) is the largest, ecological network in the world, established under a unified regulatory framework, the Habitats (Council Directive 92/43/EEC) and the Birds Directives (Directive 2009/147/EC) (Maes et al., 2012; Popescu et al., 2012). N2K stretches across all 28 EU countries, both on land and at sea, and its aim is to ensure the long-term survival of Europe's most valuable and threatened species and habitats. The network consists of Special Protection Areas (SPAs) and Sites of Community Importance (SCIs), which develop into Special Areas of Conservations (SACs). The network's core is the protection of the habitat; however, Article 2 of the Habitats Directive takes into account economic, social and cultural needs, and also regional and local features (Russo et al., 2011). The N2K is, therefore, a complex, social-ecological network (Popescu et al., 2012). Italy contributes 2613 sites to the network, which represent approximately 23% of the national land area 1. It is well recognized that N2Kprovides several ecosystem services (ES), as do the other protected areas (MEA, 2005; Kumar, 2010). However, according to Ziv et al. (2018) and Bastian (2013), there are still few studies focusing on the relationship between the provision of ES by N2K areas and conservation strategies. Ecosystem services are central and crucial for the EU Biodiversity Strategy: maintaining and enhancing ecosystem services is one of the six priority goals targeted for 2020. In order to implement the strategy, in 2012 the EU launched the Natura 2000 Biogeographical Process, a multi-stakeholders' cooperative process aimed at enhancing the actual implementation, management, monitoring, financing and reporting of the Natura 2000 network. It deals with seminars, workshops and other activities of cooperation. The Mediterranean and Continental biogeographical seminars have provided useful indications to prepare concrete, operational measures to manage the Umbrian Natura 2000 network within the framework of the SUN LIFE + Project (LIFE13 NAT/ IT/000371 2). The main aim of the SUN LIFE + project is to produce a strategic plan to manage the Natura 2000 network in the Region of Umbria and to develop the Priority Action Frameworks (PAFs). In compliance with the provisions of Article 8 (4) of the Habitats Directive, the PAFs are dedicated to prioritising the actions required to protect species and habitats. According to the SUN LIFE + project, an economic valuation must be conducted to allocate resources between the various competitive, management options, justify the budget dedicated to conservation, and define the priorities. Therefore, the aim of this study is to investigate

Therefore, the aim of this work is to present a new model, called GeoUmbriaSUIT, integrating Multicriteria Analysis and Geographic Information Systems, specifically developed for helping Decision Makers to take policy decisions about sustainability in planning. The model provides outputs which are easy to be understood by not experts; the evaluation path is traceable and transparent, thanks to back analysis. To better explain the potentiality of GeoUmbriaSUIT and its functioning, a case study about Malta is described. Our results showed that in four regions of Malta the best dimension was the environmental one, while only for two regions (Northern Harbour and Southern Harbour) respectively the economic and social dimensions obtained the best scores. The integration of MCDA-GIS resulted to be a useful tool for sustainability assessment.

Therefore, it is becoming more and more important to develop models that can measure their environmental sustainability. Although increasing attention is being paid to this sector, there is currently no standard protocol or method to assess the eco-sustainability of events. This article presents an innovative assessment procedure to measure the environmental sustainability of events. It is based on several indicators, combined by means of a multi-criteria approach and aggregated into a final index, which we called METER (Measuring Events Through Environmental Research). The METER index uses nine major operational categories, divided in sub-categories and detailed items, which cover all the main aspects concerning environmental sustainability of an event and are evaluated for all its phases, i.e. planning, organisation, implementation, post even...

L’agricoltura, che per la sua stessa natura è il settore produttivo più direttamente influenzato dagli eventi climatici, è potenzialmente esposto a grandi rischi, se il trend dei cambiamenti climatici ipotizzato da più parti a livello planetario dovesse davvero verificarsi. Il lavoro presenta i primi risultati conseguiti nell’ambito del progetto FISR “Modello integrato per l’evoluzione degli ecosistemi naturali e agricoli in relazione ai cambiamenti climatici nell’area mediterranea” (M.I.C.E.N.A.), Attività 13 (Analisi tecnico-economica delle variazioni dei principali indicatori di pressione ambientale), giunto alla fine del secondo anno di attività, dei tre previsti. L’obiettivo della ricerca è quello di verificare le conseguenze economiche ed ambientali degli eventuali cambiamenti climatici sull’agricoltura in alcune ...

The conventional MCDA approach assumes the spatial homogeneity of alternatives within the case study area, although it is often unrealistic. On the other side, GIS provides excellent data acquisition, storage, manipulation and analysis capabilities, but in the case of a value structure analysis this capability is lower. For these reasons, several studies in the last twenty years have given attention to MCDA-GIS integration and to the development of Spatial Decision Support Systems (SDSS). Hitherto, most of these applications are based only on a formal integration between the two approaches. In this paper, we propose a complete MCDA-GIS integration with a plurality of MCDA methodologies, grouped in a suite. More precisely, we considered an open-sou...

VectorMCDA assumes that each geographical object, described with a record in the attribute table, is a single lternative (geo-alternative). Each algorithm implemented in the plugin analyzes and elaborates the attributes as criteria; then it returns as an output the preference indices, adding in the attribute table one or more columns.
