Abstract

The difficult road to Integrated Coastal Zone Management implementation in Italy: Evidences from the Italian North Adriatic Regions

This work examines the evolution of Integrated Coastal Zone Management (ICZM) concepts implementation in the Italian North Adriatic Regions: Marche, Emilia Romagna, Veneto and Friuli Venezia Giulia between 2006 and 2011. In order to achieve such an objective a web-based survey has been realized and addressed to the different local and regional authorities that are competent, with different status and legal powers over coastal management. The study shows that in the considered area, although some improvements have been recorded, thanks to the transposition into the Italian legislative framework of EU provisions and above all, to local and regional efforts and initiatives, ICZM concepts are still far from being widely adopted. The weakest points reported are the fragmentation and poor coordination of the coastal management framework; the low attention given to economic data monitoring and stakeholders involvement. Furthermore, the lack of political support in the medium-long term and the availability of funds as well as the absence of monitoring and assessment strategies hinder the establishment of sustainable ICZM practices in the area. The findings of the study are then compared with other Countries, in order to draw conclusions on the barriers to ICZM implementation.

Keywords: ICZM; Italy; Implementation.

Beach Slope and Sediment-Grain-Size Trends as a Basis for Input Parameters for the SBEACH Erosion Model

Results from Storm-induced BEAch CHange (SBEACH) model calibration studies have provided new techniques and support for selection of model input parameters and interpretation of model output results. Beach and dune erosion analyses using the SBEACH erosion model in St. Johns County, Florida, demonstrated sensitivity of simulated erosion to changes of two model input parameters: sediment grain size and maximum slope prior to avalanching (MSPA). The MSPA parameter corresponds with the seaward slope of the dune or beach-berm erosion escarpment at the landward limit of the storm-induced erosion. Model calibration work demonstrated trends of these two model input parameters and of the sediment-transport rate coefficient K in relation to changes in beach slope. Evaluation of beach-slope values computed from county-wide topographic survey data in relation to the available mean sediment-grain-size data has shown clear correlation between these two parameters. This analysis provided a method for estimating mean sediment-grain-size values needed for SBEACH model input throughout St. Johns County. Results of SBEACH calibration work performed throughout St. Johns County demonstrated trends in the K and MSPA model input parameters relative to mean sediment-grain-size variations. Results of SBEACH model calibration studies in Panama City Beach, Florida; Brevard County, Florida; and on barrier islands within the Barataria Basin along the Louisiana coast demonstrated consistency with these identified trends.

Urban Coastal Development in Valencian Country: A Paradigmatic Case of Non-sustainable Development

The period between 1997 and 2007 was a period of economic expansion in Europe, and especially in Spain, where it was based on the real-estate bubble. Valencian Country, in Mediterranean coast, is a special case inside Spain because its economy specialized in the housing construction sector for non-primary houses. House construction was possible due to the increase in private debt of developers and buyers. The (artificially self-generated) expectation of strong annual increases in housing values maintained an intense construction activity. In 2007, the price of houses peaked and then began a process of impoverishment due to the payment of debts. Today this process is still continuing, but extensive data on the complete cycle of expansion and regression of the housing bubble are already available. This paper presents a real description of the complete process of non-sustainable urban development in Valencian Country and analyzes the process in economic, social and environmental terms. Finally, a general scheme of the process and a system of sustainability is proposed.

Keywords: Housing market; Property rights; Real-estate bubble; Sustainable urban development.

Time is of the essence: adaptation of tourism demand to climate change in Europe

This study analyses the potential impact of climate change on tourism demand in the European Union (EU) and provides long-term (2100) projections accounting for climate adaptation in terms of holiday duration and frequency. Our analysis is based on hedonic valuation of climatic conditions combining accommodation and travel cost estimations. Our results suggest that climatic change is likely to affect the relative attractiveness of EU regions for tourism activities. In certain regions, most notably the Southern EU Mediterranean regions, climate condition in 2100 could under current economic conditions, lower tourism revenues for up to −0.45 % of GDP per year. On the contrary, other areas of the EU, most notably Northern European regions would gain from altered climatic conditions, although these gains would be relatively more modest, reaching up to 0.32 % of GDP on an annual basis. Our results also suggest that the change in holiday duration would be more beneficial than the change in holiday frequency in view of mitigating the cost of climate change. These two time dimensions of adaptation are likely to be conditioned by broader societal and institutional factors, however.

Keywords: Tourism demand; Climate change.
