The best description of water resources for Grand Turk was offered by Pérez Monteagudo (2000) who suggested that rain water was insufficient to ensure a regular water supply although water catchment was being practised and water catchment possibilities had been analysed. Limestone islands, mostly flat and low lying, have few possibilities for large scale surface storage, and groundwater lenses exist in very delicate equilibrium with saline seawater, and are highly likely to collapse due to sea level rise, improper extraction, drought, tidal waves or other extreme event. A study on the impact of climate change on water resources in the Turks and Caicos Islands is a challenging task, due to the fact that the territory of the Islands covers different environmental resources and conditions, and accurate data are lacking. The present report is based on collected data wherever possible, including grey data from several sources such as the Intergovernmental Panel on Climate Change (IPCC) and Cuban meteorological service data sets. Other data were also used, including the author’s own estimates and modelling results. Although challenging, this was perhaps the best approach towards analysing the situation. Furthermore, IPCC A2 and B2 scenarios were used in the present study in an effort to reduce uncertainty. The main conclusion from the scenario approach is that the trend observed in precipitation during the period 1961 - 1990 is decreasing. Similar behaviour was observed in the Caribbean region. This trend is associated with meteorological causes, particularly with the influence of the North Atlantic Anticyclone. The annual decrease in precipitation is estimated to be between 30-40% with uncertain impacts on marine resources. After an assessment of fresh water resources in Turks and Caicos Islands, the next step was to estimate residential water demand based on a high fertility rate scenario for the Islands (one selected from four scenarios and compared to countries having similar characteristics). The selected scenario presents higher projections on consumption growth, enabling better preparation for growing water demand. Water demand by tourists (stopover and excursionists, mainly cruise passengers) was also obtained, based on international daily consumption estimates. Tourism demand forecasts for Turks and Caicos Islands encompass the forty years between 2011 and 2050 and were obtained by means of an Artificial Neural Networks approach. for the A2 and B2 scenarios, resulting in the relation BAU>B2>A2 in terms of tourist arrivals and water demand levels from tourism. Adaptation options and policies were analysed. Resolving the issue of the best technology to be used for Turks and Caicos Islands is not directly related to climate change. Total estimated water storage capacity is about 1, 270, 800 m3/ year with 80% capacity load for three plants. However, almost 11 desalination plants have been detected on Turks and Caicos Islands. Without more data, it is not possible to estimate long term investment to match possible water demand and more complex adaptation options. One climate change adaptation option would be the construction of elevated (30 metres or higher) storm resistant water reservoirs. The unit cost of the storage capacity is the sum of capital costs and operational and maintenance costs. Electricity costs to pump water are optional as water should, and could, be stored for several months. The costs arising for water storage are in the range of US$ 0.22 cents/m3 without electricity costs. Pérez Monteagudo (2000) estimated water prices at around US$ 2.64/m3 in stand points, US$ 7.92 /m3 for government offices, and US$ 13.2 /m3for cistern truck vehicles. These data need to be updated. As Turks and Caicos Islands continues to depend on tourism and Reverse Osmosis (RO) for obtaining fresh water, an unavoidable condition to maintaining and increasing gross domestic product(GDP) and population welfare, dependence on fossil fuels and vulnerability to increasingly volatile prices will constitute an important restriction. In this sense, mitigation supposes a synergy with adaptation. Energy demand and emissions of carbon dioxide (CO2) were also estimated using an emissions factor of 2. 6 tCO2/ tonne of oil equivalent (toe). Assuming a population of 33,000 inhabitants, primary energy demand was estimated for Turks and Caicos Islands at 110,000 toe with electricity demand of around 110 GWh. The business as usual (BAU), as well as the mitigation scenarios were estimated. The BAU scenario suggests that energy use should be supported by imported fossil fuels with important improvements in energy efficiency. The mitigation scenario explores the use of photovoltaic and concentrating solar power, and wind energy. As this is a preliminary study, the local potential and locations need to be identified to provide more relevant estimates. Macroeconomic assumptions are the same for both scenarios. By 2050, Turks and Caicos Islands could demand 60 m toe less than for the BAU scenario.

This paper focuses on several key economic issues relevant to climate change. Given the fact that changes in climate are projections using the best available data, it examines the economic principles of uncertainty and the precautionary approach, and then continues to address the key drivers of climate change. Climate change is expected to result in negative impacts and, in this regard, the consequences of anticipated rising temperatures and sea levels as well as changes in precipitation that may result in flooding and/or drought are addressed. However, the situation is not all negative and, as such, the opportunities that are likely to arise through adaptation and mitigation are discussed especially with respect to the Caribbean. In this regard and recognizing that it would be useful to Caribbean policymakers to utilize these opportunities and to address the negative impacts, the Economic Commission for Latin America and the Caribbean (ECLAC), through its subregional headquarters for the Caribbean, is spearheading a review of the economics of climate change in the Caribbean with a view to providing quantitative information to stakeholders in dealing with climate change. The paper makes recommendations for the Caribbean to address climate change at the national level. These include macroplanning; promotion of energy efficiency; creation of incentives to obtain support for implementation of alternative energy technologies; maintaining the will among stakeholders on a sustained basis for addressing climate change; and the conduct of relevant research into varieties of plants and animals that could adapt to changing climatic conditions. Finally, it must be recognized that to successfully combat climate change, the threats and opportunities must be properly assessed as part of an ongoing region-wide system of risk management, which should not be incidental, but integral, to national and regional planning and forecasting for the future.

La evolución del consumo de energía tiene una estrecha relación con los cambios ocurridos en la actividad económica con la estructura económica como indicadores referentes a condiciones propicias para la implementación de estándares de eficiencia energética. A partir del análisis realizado por el equipo de trabajo en Nicaragua en el marco del programa BIEE (Base de Indicadores de Eficiencia Energética), se realizó un exhaustivo rastreo de indicadores existentes en materia de consumo energético por sectores económicos, así como una depuración de los posibles vacíos que podrían convertirse en futuras oportunidades de inversión en investigación y desarrollo referente al tema de la eficiencia energética. Los resultados que se muestran en el presente informe corresponden a los indicadores que poseen relevancia a escala nacional. Con estos resultados se establece un punto de partida para una actualización constante de indicadores de monitoreo de la eficiencia energética.
