My research project aimed to develop recommendations to support the delivery of additional marine management actions in Gibraltar. The rationale for this study was to bridge knowledge gaps on the marine environments around Gibraltar, through a review of literature on UK and UK Overseas Territories (UKOT) marine environments and management policies. The study builds upon the Marine Climate Change Impacts Partnership (MCCIP) reports for UKOTs which includes Gibraltar as part of the Mediterranean region. I assessed the key climatic drivers, human threats, impacts, management issues and management solutions identified in the MCCIP reports for the UK and UKOTs to compare similarities and differences. To build upon this information I undertook a critical literature review of academic papers relevant to marine management in the UK and UKOTs. I also reviewed the Department of the Environment, Sustainability, Climate Change and Heritage (DESCCH) ‘Good Environmental Status’ report for Gibraltar, conducted as part of the Marine Strategy Framework Directive (MSFD), to identify specific information about Gibraltar’s marine environments. Finally, I conducted my own Rapid Vulnerability Assessment (RVA) for two habitats in Gibraltar, intertidal rocky shores and natural and artificial reefs. A RVA allowed me to identify the vulnerability of these habitats to the impact of climate change and human threats by assessing their level of risk to these threats and their capacity to cope. By synthesising the data from all the literature reviewed and the outcomes of the RVA I was able to make informed recommendations on ways to improve the management of Gibraltar’s marine and coastal environments. Recommendations have been categorised into short term, those which can be planned and implemented in the next 10 years and long term, those where initial planning could start within the next 10 years, but implementation and/or delivery is expected to happen in 10 years or more.
