<div>The Intergovernmental Coordination Group for the Tsunami and other Coastal Hazards Warning System for the Caribbean and Adjacent Regions (ICG/CARIBE EWS) was established in 2005 as a subsidiary body of the IOC-UNESCO with the purpose of providing efficient assistance on tsunami risk reduction to Member States in the Caribbean region after the lessons learnt from the 2004 Indian Ocean tsunami.</div><div> </div><div>The aim of the work that we present here, is strengthen the capacities of early warning and response for tsunamis in the Caribbean through the development of community-level tsunami inundation maps for select coastal communities and a technical guide; both to support their preparation for and response to tsunamis. The selected communities under study are in Antigua and Barbuda, Barbados, Dominican Republic, St. Vincent and the Grenadines, and Trinidad and Tobago.</div><div> </div><div>To this end, we use Tsunami-HySEA model, developed by EDANYA Group, which implements in the same code the three phases of an earthquake generated tsunami: generation, propagation and coastal inundation. At the same time it is implemented in nested meshes with different resolution and multi-GPU environment, which allows much faster than real time simulations. Due to this advantage it can produce a 4 h simulation in a 60 arcsec resolution grid for the whole Caribbean Sea in less than 4 min with a single general-purpose GPU.</div><div> </div><div>Once provided the seismic parameters to reproduce the main scenarios that could affect to the nominated communities, and the topobathymetry data available from the study area, an exhaustive process of construction of 4 levels nested meshes was performed for each localization. Secondly, the events are simulated in order to obtain, among others, maximum depth in coast inundation with 5 meters resolution. Finally, all of these data allow us to make a detailed inundation map as a contribution to furthering tsunami risk assessment.</div><div> </div><div>Acknowledgements.

2004 Tsunami

The 2004 Indian Ocean tsunami caused enormous loss of lives and damage to property in Sri Lanka and in several other countries bordering the Indian Ocean. One way of mitigating potential loss of lives from a similar event in the future is through early warning and quick evacuation of vulnerable coastal communities to safer areas, and such evacuation planning is usually carried out based on inundation maps. Accordingly, the present paper outlines the numerical modelling carried out to develop tsunami inundation maps on a grid of 10 m resolution for three cities on the south coast of Sri Lanka. The results give the tsunami arrival time contours and the spatial distribution of the extent of inundation, the maximum flow velocities as well as the hydrodynamic force in these three cities due to an event similar to the 2004 tsunami.

Abstract. Scientific evidence is critical to underpin the decisions associated with shoreline management, to build climate resilient communities and infrastructure. We explore the role of waves, storm surges and sea level rise for the Caribbean region with a focus on coastal impacts in the eastern Caribbean islands. We simulate past extreme events and a worst-case scenario, modelling the storm surges and waves, suggesting a storm surge might reach 1.5 m, depending on the underwater topography. Coastal wave heights up to 12 m offshore and up to 5 m near the coast of St Vincent are simulated with a regional wave model. We deliver probabilistic sea level projections for 2100, with a low probability/high impact estimate of possible sea level rise up to 2.2 m, exceeding the 1.8 m global estimate for the same scenario. We introduce a Combined Vulnerability Index, which allows a quantitative assessment of relative risk across the region, showing that sea level rise is the most important risk factor everywhere, but wave impacts are important on windward coasts, increasing to the north, towards the main hurricane track. Our work provides quantitative evidence for policy makers, scientists, and local communities to actively prepare for and protect against climate change.

<abstract> <p>COVID-19 emerged initially from Wuhan, Hubei province, China, in late December 2019, and since then, it has spread globally to be declared a pandemic by the World Health Organization. The Caribbean region started reporting COVID-19 cases in early March 2020, triggering new regional public health crises. The initial suspects and confirmed cases across the Caribbean countries were mainly imported cases and from cruise ships. The clinical manifestations varied from fever, cough, and malaise in mild cases to acute respiratory distress syndrome (ARDS) and shock in severe cases. The Caribbean Public Health Agency has provided frequent updates on the preventive strategies and quarantine measures across the Caribbean member states. COVID-19 has had a serious impact on the Caribbean region's health system, economy, and psychology. This review presents the Caribbean perspective of COVID-19, detailing the epidemiology, clinical manifestations, diagnosis, management, and preventive and surveillance measures. Vaccine hesitancy was found to be a major challenge that needs appropriate health education strategies to address the public. Strong leadership and regional collaboration among the Caribbean member states are necessary to provide optimal real-time data to the public and implement appropriate and effective guidelines in the island states.</p> </abstract>

Scotland is gradually coming to terms with its involvement in slavery and colonialism as part of the British Empire. This article places the spotlight on the lives of African Caribbean people who were residents of Edinburgh during the eighteenth and nineteenth centuries. I discuss their varied experiences and contributions: from runaways and men fighting for their freedom in the Scottish courts to women working as servants in city households or marrying into Edinburgh high society. The nineteenth century saw activism among political radicals from abolitionists to anticolonialists; some of these figures studied and taught at Edinburgh University. Their stories reflect the Scottish capital’s many direct connections with the Caribbean region.

AbstractThe countries of the Wider Caribbean Region (WCR) are linked economically by their transboundary living marine resources. The region is facing a continued decline of these resources. Science is improving our understanding of the human contributions to this decline, but national policies and programmes have not kept pace with this understanding. The Caribbean Regional Seas Programme and its Cartagena Convention and Protocols provide the regional legal framework for protection and sustainable management of the WCR's living marine and coastal resources. This article focuses on the Cartagena Convention's Protocol for biodiversity conservation, the Protocol Concerning Specially Protected Areas and Wildlife (SPAW), arguing that governments and organizations need to significantly increase participation in this regional treaty regime to effectively address transboundary environmental challenges. A new initiative, the Global Environment Facility-supported Caribbean Large Marine Ecosystem project, will help in this effort. International policy supports strengthened regional seas programmes. It is now imperative for all levels and sectors to assist governments in strengthening this important treaty regime for biodiversity conservation in the Wider Caribbean Region.
