Greenhouse gas (GHG) emissions from human activities are driving climate change and are currently at their highest levels in history. The international community, through the United Nations process, places great emphasis on the decarbonisation of our economies across all sectors. GHG emissions from maritime transport, even if considered the most carbon efficient method of transportation, are projected to increase if no action is taken to decarbonise, and thus pressure has extended to the maritime sector to contribute to the significant GHG emission cuts necessary. The paths by which the maritime sector can contribute to the achievement of the international target of GHG reduction by 2050 are still being determined, but numerous promising options exist. This paper aims to provide an overview of action towards decarbonisation by the international maritime sector, and to assess how Cyprus, an important flag state, can contribute to decarbonisation efforts. A participatory approach was used, through implementation of the EIT Climate-KIC’s Deep Demonstrations methodology, as part of the ‘ Zero-Net Emissions, Resilient Maritime Hubs in Cyprus’ project. The results were used to identify a portfolio of actions related to policy and regulatory development, education and re-skilling, technological development, and operation optimisation, which can support the decarbonisation of the maritime sector in Cyprus.

Promoting urban sustainability has been on the agenda of researchers, planners, and policymakers. This paper uses quantitative and qualitative approaches to evaluate the sustainability of the Cypriot city of Limassol through transportation and green spaces indicators. The quantitative approach relies on a geostatistical evaluation of six indicators to describe the transportation sector and the proximity and provision of urban green spaces. The qualitative approach is based on a questionnaire (N = 387) conducted in the city. Results showed that car trips represent more than 90% of the modal share, and around 90% of the city’s transportation infrastructure is designed for cars. In terms of urban green spaces, only 5% of the areas with the highest population density are within 300 m of a green space > 2 ha. The questionnaire confirmed that 71% of the residents are not satisfied with the conditions provided by the city to walk and cycle, while 76% are not satisfied with the green spaces available in the city. This study contributes to informing planners and decision-makers about the need to promote walking, cycling, and greening policies to make Limassol and other similar cities more sustainable.

This study presents the development and application of an integrated Geographic Information System (GIS)-based Marine Spatial Planning (MSP) framework for identifying suitable offshore aquaculture development zones in Cyprus. The methodology, developed within the OS AQUA project, combines environmental exclusion analysis, weather and proximity assessment, stakeholder and policy evaluation, and carrying-capacity estimation within a unified spatial decision-support framework. A sequential three-phase analytical workflow was applied to progressively refine candidate offshore areas under environmental, operational, infrastructural, regulatory, and governance considerations. The analysis identified four candidate offshore aquaculture zones in Cyprus—Xylofagou West, Larnaka (Faros area), Governor’s Beach, and Aphrodite Hills/Avdimou—demonstrating comparatively favourable conditions for offshore aquaculture development. The results highlight the importance of integrating environmental compatibility, operational feasibility, accessibility, stakeholder acceptance, and sustainability considerations within offshore aquaculture planning processes. Carrying-capacity assessment further indicated substantial offshore production potential under precautionary operational assumptions. Beyond the Cyprus case study, the proposed GIS-MSP framework offers a transferable methodological roadmap for offshore aquaculture zoning, Allocated Zones for Aquaculture (AZA) establishment, and sustainable marine spatial planning in the Mediterranean region.

Coastal flooding can result from multiple interacting drivers and can be a complex, challenging topic for learners to grasp. Interactive learning with apps offers new opportunities for improving comprehension and engagement. We present the Floodport app, an educational interactive tool that puts students in the role of coastal risk analysts exploring how natural hazards threaten port safety. Users have to adjust key parameters, including high tides, storm surges, terrestrial rainfall contribution, sea-level rise, and engineered features such as dock height. These forces, individually or jointly, result in water-level rises that may flood the app’s port. The app supports exploration of mitigation designs for the port. Developed in Excel and Python 3.11.4 and deployed as an R/Shiny application, Floodport was used as a classroom game by 153 students with no prior knowledge on coastal flooding concepts. Pre–post survey statistical analysis showed significant learning gains and positively correlation with willingness to engage further. Floodport was found to be a useful tool for basic introduction to flooding concepts. The results indicate strong pedagogical promise and potential for using the app beyond the classroom, in contexts such as stakeholder engagement and training.
