The aim of this study was to develop a model for the evaluation of infrastructures vulnerability to forest fires in Wildland-Urban Interfaces (WUI), based on integrated environmental and operative data and measures. The model, based on GIS tools, gives indications on:-maps on infrastructures fire exposition classified considering their different vulnerability-significant factors influence in determining a specific vulnerability level The model considers, as input data: types of vegetation, numbers and related surfaces of historical fire events, slope and operational difficulties related to fire suppression (both for ground and aerial means of intervention). The present study evaluated variables connected to forest environment; however the model could be tuned to include data from different sectors (i.e. building characteristics and materials evaluation). The considered variables, giving indication on environmental risk aspects, are expression of apparently not comparable parameters (i.e. vegetation inflammability, water point road distance) and consequently expressed by different measurement units. To overcome this problem a Multi-Criteria Decision Analysis technique (Analytic Hierarchy Process-AHP) was used to compare cited data. The AHP is based on interviews with experts (operative room managers, firebosses, researchers) and is a statistical method both for relating subjective preferences of singles or groups of stakeholders within a decision-making process and for assigning a level of importance (weight) to each variable considered in the model. The final product is a map classifying the risk to wildfire for the buildings in WUI areas; it is useful for manager in planning prevention actions and during the attack phases in establishing priorities. © Interscience Communications Limited, 2015.

Environmental context Plastic materials are accumulating in the marine environment where they can now be found in the remotest areas of the world's oceans. Microplastics (plastic particles ≤5mm), abundant in marine surface waters, are also found in neritic and pelagic waters of Mediterranean marine protected areas. Microplastics can accumulate along marine food chains, having noxious effects on marine organisms at different trophic levels and creating a serious threat to marine ecosystems. Abstract Floating plastic debris tends to fragment into smaller pieces, termed microplastics, which may increase the likelihood of ingestion of plastics by marine organisms entering the food web. This study analyses the amount and spatial distribution of microplastics and zooplankton in an area near Asinara National Park (NW Sardinia) and overlapping the Pelagos Sanctuary (Mediterranean Sea). Analysis showed microplastics in 81% of the 27 samples analysed, with a mean value of 0.17±0.32 items m-3. From geographic information system processing of the data, microplastics appeared more abundant (by a factor of four) in the pelagic than in the neritic environment, and showed a size range of the same order as major zooplanktonic taxa determined in the area. These findings suggest a potential risk of mesozooplankton and species preying on plankton mistaking microplastics for food. Further functional and toxicological studies are therefore necessary to assess the hazard associated with microplastics in the marine food web. © CSIRO 2015.

In Southern European countries wildfires are the most natural threat to forests and wooded areas. Over the last decade, public and scientific debates on forest fire management have increased. Helicopters and airtankers are extremely effective fire suppression means, but they are also very expensive. Studies on the improved performance of suppression for the enhancement of firefighting organization are still needed. Consequently to make a plan for the distribution of financial resources to be divided between fire suppression and fire prevention actions in terms of fuel management is not possible. The aim of this study is to compare the helicopter’s forest firefighting activity in Tuscany (central Italy) over two periods: between 1998–2000 and 2001–2005 when five and ten helicopters were respectively assigned. For both periods (1998–2000 and 2001–2005) the following were analyzed: the number of forest fires and the burned area with or without helicopter intervention and the position of the helicopter bases in relation to the fire. The results showed that a feet of 10 helicopters is oversized, in relation to the fire regime of Tuscany, suggesting the need to evaluate a reduction in the feet. Financial resources may be thus made available for more profitable fire prevention activities, such as, active fuel management. The results also showed where there is the need to improve the helicopter efficiency via the re–management as regards the positioning of their bases. © 2014 University of Zagreb.

The hydrodynamic action of wind and the distribution of biomass of seagrass meadows in a non-tidal eutrophic lagoon (Orbetello Lagoon, Tuscany, Italy) were analysed for correlations by simulation with a Wave Exposure Model (WEMo) on 5-year data series. WEMo and statistical analysis established a weak direct correlation between the areas that the model identified as being subject to resuspension and transport of sediment and those actually colonised by seagrass. A significant difference was found between surface and bottom hydrodynamics. The areas that the model identified as exposed to higher energy surface hydrodynamics proved to be inversely correlated with seagrass biomass. Multivariate statistical analysis ordered the model variables according to their relative importance. The model indicated the need for further study, demonstrating its utility for environmental management of eutrophic lagoons. © 2013 Elsevier Ltd.

Genetically modified trees are the result of modern plant breeding. Its introduction into the environment for experimental purposes or wider cultivation is defined differently from country to country. Public opinion is divided! Conducted research are part of the activities within the COST Action FP0905 "Biosafety of forest transgenic trees", which aims to collect information and define the scientific attitude on genetically modified trees as a basis for future European Union (EU) policy in this field. The collected information refer to eight countries: four EU member states (Italy, Slovenia, Romania and Bulgaria) and four countries in the process of pre-accession (Croatia, Montenegro, Serbia and Bosnia and Herzegovina). A comparative analysis involved the state of forest resources (area of forest land and forest cover), forestry legislation, legislation relating to genetically modified organisms and the general public attitude on this issue. The collected information provide a good basis for understanding this issue in order to define a clear scientific attitude as a recommendation.
