The regionwide study of the effects of climate change in the coastal areas of Latin America and the Caribbean has been divided into four main parts in line with the comprehensive risk-assessment methodology that was developed as research progressed. The outputs of this regional study are presented in four core documents: an analysis of the factors that are driving climate change, a study on the vulnerability of coastal areas, an evaluation of the impacts of climate change and an exploration of how all these different factors can be brought together in an assessment of the risks associated with some of the impacts of climate change on the region’s coastal areas.

Climate change affects the fundamental bases of good human health, which are clean air, safe drinking water, sufficient food, and secure shelter. Climate change is known to impact health through three climate dimensions: extreme heat, natural disasters, and infections and diseases. The temporal and spatial climatic changes that will affect the biology and ecology of vectors and intermediate hosts are likely to increase the risks of disease transmission. The greatest effect of climate change on disease transmission is likely to be observed at the extremes of the range of temperatures at which transmission typically occurs. Caribbean countries are marked by unique geographical and geological features. When combined with their physical, infrastructural development, these features make them relatively more prone to negative impacts from changes in climatic conditions. The increased variability of climate associated with slow-moving tropical depressions has implications for water quality through flooding as well as hurricanes. Caribbean countries often have problems with water and sanitation. These problems are exacerbated whenever there is excess rainfall, or no rainfall. The current report aims to prepare the Caribbean to respond better to the anticipated impact of climate change on the health sector, while fostering a subregional Caribbean approach to reducing carbon emissions by 2050. It provides a major advance on the analytical and contextual issues surrounding the impact of climate change on health in the Caribbean by focusing on the vector-borne and waterborne diseases that are anticipated to be impacted directly by climate change. The ultimate goal is to quantify both the direct and indirect costs associated with each disease, and to present adaptation strategies that can address these health concerns effectively to benefit the populations of the Caribbean.

The energy sector is a dominant one in Trinidad and Tobago and it plays an important role in the twin-island republic‟s economy. In 2008, the share of the energy sector in gross domestic product (GDP) amounted to approximately 48% while contributing 57% to total Government revenue. In that same year, the sector‟s share of merchandise exports was 88%, made up mainly of refined oil products including petroleum, liquefied natural gas (LNG), and natural gas liquids (Central Bank of Trinidad and Tobago, 2009). Trinidad and Tobago is the main exporter of oil in the Caribbean region and the main producer of liquefied natural gas in Latin America and the Caribbean. The role of the country‟s energy sector is, therefore, not limited to serving as the engine of growth for the national economy but also includes providing energy security for the small island developing States of the Caribbean. However, with its hydrocarbon-based economy, Trinidad and Tobago is ranked seventh in the world in terms of carbon dioxide (CO2) emissions per capita, producing an estimated 40 million tonnes of CO2 annually. Almost 90% of these CO2 emissions are attributed directly to the energy sector through petrochemical production (56%), power generation (30%) and flaring (3%). Trinidad and Tobago is a ratified signatory to the United Nations Framework Convention on Climate Change and the Kyoto Protocol. Although, as a non-Annex 1 country, Trinidad and Tobago is not required to cut its greenhouse gas emissions under the Protocol, it is currently finalizing a climate change policy document as well as a national energy policy with specific strategies to address climate change. The present study complements the climate change policy document by providing an economic analysis of the impact that climate change could have on the energy sector in Trinidad and Tobago under the Intergovernmental Panel on Climate Change alternative climate scenarios (A2 and B2) as compared to a baseline situation of no climate change. Results of analyses indicate that, in the short-run, climate change, represented by change in temperature, is not a significant determinant of domestic consumption of energy, electricity in particular, in Trinidad and Tobago. With energy prices subsidized domestically and fixed for years at a time, energy price does not play a role in determining electricity demand. Economic growth, as indicated by Gross Domestic Product (GDP), is the single major determinant of electricity consumption in the short-run. In the long-run, temperature, GDP, and patterns of electricity use, jointly determine electricity consumption. Variations in average annual temperature due to climate change for the A2 scenario are expected to lead to an increase in electricity consumption per capita, equivalent to an annual increase of 1.07% over the 2011 baseline value of electricity consumption per capita. Under the B2 scenario, the average annual increase in electricity consumption per capita over the 2011 baseline value is expected to be 1.01%. The estimated economic impact of climate change on electricity consumption for the period 2011-2050 is valued at US$ 142.88 million under the A2 scenario and US$ 134.83million under the B2 scenario. These economic impact estimates are equivalent to a loss of 0.737% of 2009 GDP under the A2 climate scenario and a loss of 0.695% of 2009 GDP under the B2 scenario. On the energy supply side, sea level rise and storm surges present significant risks to oil installations and infrastructure at the Petroleum Company of Trinidad and Tobago (PETROTRIN) Pointe-a-Pierre facilities (Singh and El Fouladi, 2006). However, data limitations do not permit the conduct of an economic analysis of the impact of projected sea level rise on oil and gas production.

The present study analyzes the potential opportunities and risks involved in employing biotechnologies in the Caribbean region. This information would support developmental policies in the areas of food security, climate change and poverty reduction. The report provides a brief overview of biotechnology development, covering industrial and other microbial biotechnologies, tissue culture and molecular biology. Details of opportunities and risks of biotechnology development are provided for agricultural, industrial, environmental, industrial and medical biotechnology, with information on the global agreements for regulation of genetically modified organisms. The rest of the report analyzes the Caribbean situation. Biotechnology applications, opportunities and risks in the Caribbean are described in detail, with focus on industrial and agricultural biotechnology, and including climate change and constraints to biotechnology development. The report closes with a discussion of the applicability of biotechnology to the region in terms of agricultural, industrial, environmental, medical and marine biotechnology. Conclusions and recommendations are provided. The main conclusion of the study is that there is an urgent need for development and use of biotechnology in the Caribbean, especially in nonagro- biotech sectors, to address food security, climate change, poverty, environmental degradation, among other issues. In so doing, countries must take advantage of the opportunities presented by biotechnology to gain competitive advantage and benefits, while at the same time put measures in place to reduce or remove associated risks. This must be done taking into consideration economic as well as social and cultural issues.

This effort to study the effects of climate change in the coastal areas of Latin America and the Caribbean has been divided into four main parts in line with the comprehensive risk-assessment methodology developed. The outputs of this regional study are presented in four core documents: an analysis of coastal dynamics and climate variability, a study on the vulnerability of coastal areas, an evaluation of the impacts of climate change and an exploration of how all these different factors can be brought together in an assessment of the risks of the impacts of climate change on the region’s coastal areas. The overall objective of this study is to compile the specific types of information required in order to analyse the economic impacts of climate change in the coastal areas of Latin America and the Caribbean. The area covered by the study encompasses the coastlines of Latin America and the Caribbean (an area totalling approximately 72,182 km in length).
