The Jamaican tourism industry is very climate sensitive, and, like most Caribbean islands, Jamaica's main tourism product is coastal, centered on "sun, sea and sand". The island is susceptible to many risks posed by climate change, including sea level rise and extreme events, with resultant impacts such as beach erosion, flooding, saline intrusion into aquifers and general coastal degradation. This paper evaluates the relative vulnerability of beach versus non-beach tourism in Jamaica, using 43 pre-determined literature-linked indicators. These comprise bio-geophysical, social, technological, economical, technological and institutional factors. Four case areas are assessed using multi-criteria decision analysis to derive vulnerability scores for each area. The study finds that non-beach tourism operations should not be automatically perceived as less vulnerable than beach-based operations. Sustainable adaptation options are complex and numerous, and overall beach tourism businesses have better insurance, emergency savings, disaster plans and backup power facilities, among others. They also have the advantage of being in business longer than the inland resorts, a firmer business structure and an extensive marketing budget. In the long term, better adaptation and planning by inland businesses could change this balance. [ABSTRACT FROM AUTHOR]

This paper examines a pathway for small islands to replace fossil fuels by renewable sources, such as wind and solar, up to 100% to economically achieve energy security and satisfy The Paris Agreement to limit temperature rise as close as possible to 1.5 °C, in an economically beneficial manner. Using Jamaica, as an example, it is shown that the introduction of intermittent renewable energy to an island grid, which is electrically isolated, relying totally on itself for backup, causes serious frequency fluctuations and load shedding. Simulations show that a Battery Energy Storage System (BESS) using Li-ion batteries can be employed to economically overcome these problems. It is also noted that the cost of batteries with longer discharge capacity is on the decline and their use is expected to be become economical in about 10 years. Looking at the reported pathway to satisfy The Paris Agreement, a 2-phase pathway is suggested. In the Phase 1 (2020–2030) 30% integration of intermittent renewables with BESS backup can be implemented in a manner that is not economically burdensome whilst the remaining fossil fuel system can provide the firm energy needed. In Phase 2 (2030–2055), more renewables can be implemented, provided sufficient long term storage, including batteries, can be added to provide firm energy. By 2030 the cost of such storage is expected to fall resulting in increased deployment without a financial burden to the islands. Ideally, during the period 2020 to 2055, there should be no new additions of fossil fuel plants and retiring plants should be replaced by renewable energy plants; although an account is necessary for plants already in the planning and development stages. The leeway period of 2020–2030 should be used for the preparation and planning of adding up to 100% renewables in all sectors. • Sensitivity of isolated island grid systems to intermittent renewables. • Demonstration of frequency regulation control using simulations of Li-ion battery storage. • Mitigation pathway utilizing 100% renewable to limit temperature rise to 1.5″.C [ABSTRACT FROM AUTHOR]
