Coastal areas are generally known as high-usage areas for residential, recreational, and tourism purposes. Coastal residents, as well as local visitors, therefore, can play an important role in protecting coastal resources. The purpose of this study was to identify important factors that could promote residents' environmentally responsible behaviour (ERB). The two concepts, place attachment and attitudes toward tourism development (ATTD), were included to verify causal relationships of ERB. For data analysis, confirmatory factor analysis (CFA) and structural equation modelling (SEM) were conducted. Study results showed that place identity fully mediated the relationship between place dependence and ERB. With respect to the two dimensions of ATTD, there was a positive relationship between perceived benefits and ERB, while perceived concerns mediated this relationship. To promote ERB, the study emphasized the importance of developing place identity by providing diverse economical, socio-cultural, and recreational coastal benefits. In addition, involving those residents, who are positively and negatively impacted by tourism development, in the process of sustainable tourism development will develop more effective sustainable development strategies by reflecting local residents' opinions and preferences.

The sea-level rise phenomenon affects several socio-economic and ecological aspects worldwide, particularly in terms of coastal erosion and saltwater intrusion. While the Mediterranean region is showing an increase vulnerability to the sea-level rise, in this study, we implement the Coastal Vulnerability Index (CVI), between 2005 and 2013, on the Southern Lebanese coast. The selection of this study area is related to its commonly known vulnerable sandy beaches. The CVI is derived from six physical and geological variables that are estimated using Geographical Information System and Remote Sensing techniques. Results show that this eastern Mediterranean coast has a moderate (66% of its total lengths) to high coastal vulnerability (30% of its total lengths) to the sea-level rise. As predicted, sandy beaches in our study area represent the most vulnerable regions. On the other hand, an absence of a Pearson correlation between the amount of the sea level rise and the sea surface temperature, is shown. It is probably related to the direct human interference that eclipsed the climate change as the main driving force in that period (i.e. 2005–2013). In this context, we propose an intervention strategy that focuses on offering “soft” techniques performed at the sandy beaches and in dune systems. Stakeholders are encouraged to implement this approach to combat the coastal vulnerability of these areas. And by applying the proposed method to other limited-resources/datasets countries, regional organizations and institutions could have vital information to reduce the impact of the SLR at a larger-scale.

Coastal zones and marine areas attract a large number of people and productive activities, a fact that causes important pressures on ecosystems and affects the cohesion of local societies. These areas – that is, the large number of islands and the extended coastline - are important for Greece, because of its geography. Coastal zones and marine areas are vulnerable socio-spatial systems exposed to menaces, such as: sea level rising, desertification phenomenon, built-up areas excessive expansion etc., thus, spatial planning is required for their sustainable management, something that is not always easy to implement. The paper aims to discuss key issues of spatial planning emerged from the ratification of an integrated framework for marine planning in the national spatial planning system. For better understanding of the particularities of Greek spatial planning procedures, the island of Crete is chosen as a case study area, where synergies, conflicts and methodological issues come up at regional and local level.

More than 70% of the European population live in cities, which are affected by several critical issues, such as the depletion of energy and material resources, decreasing of food security, increasing of green-house gas emissions levels with relevant environmental impacts and management issues (e.g. waste treatment). Urban areas emit about 80% of the global CO2 emissions and they are responsible for about 80% of global energy consumption.
Therefore, cities offer a possible action field for decisive local initiatives to address sustainability challenges, especially in terms of policy and societal actions, inspiring specific projects, which could be translated into more systematic programs at higher levels of governance. In order to mitigate climate change effects, the European energy policy is focused on buildings’ energy efficiency due to its substantial savings’ potential. This paper describes the integrated design approach developed by the Research Unit of the Department of Architecture of the University of Bologna, (RU) with the aim to identify scenarios of resilient actions for renovating existing buildings and districts, as well as for framing effective refurbishment design criteria at district level. This integrated approach combines energy efficient solutions and technologies, which have positive and sustainable impact on the environment with customer oriented strategies in order to ensure gains and customers’ expectations and requirements at the same time.
The paper highlights: the link between mitigation strategies and the built environment; the application of the proposed Integrated Design Approach (IDA) inside the real context of Bolognina neighbourhood (Bologna, IT); the link between life cycle assessment (LCA), mitigation measures and IDA; analysis of results, impacts and potentialities of replication.
