An assessment of the economic impact of climate change on the Agriculture Sector in Guyana

Climate change is anticipated to have potentially disastrous impacts on the economic viability of the agricultural sector, insomuch as traditional agricultural practices render the agricultural sector climate-dependent. Increased temperatures and increased intensity, timing and occurrence of hydro events are expected to challenge plant and animal viability. Under such circumstances, vector control is expected to become more difficult, which may further prejudice the prosperity of plant, livestock and fisheries growth. The impact is expected to be on the quality of agricultural produce and thereby, indirectly, on human health outcomes. The key threat mechanisms are debilitated plant vitality and increased propagation of pests, as drought periods increase the breeding of vectors through water pooling and soil erosion associated with the increased intensity of hydro events. In addition, climate change is likely to affect crop productivity in specific geographical areas through its impact on growing seasons and crop patterns, to the extent that crop varieties cannot adapt.

The economics of climate change in the Caribbean

The present volume captures the results of the studies conducted during Phase 2 of the RECCC project to date. Chapter 1 provides the contextual framework within which the assessments were conducted and Chapter 2 focuses on the emissions scenarios as set out by the Special Report on Emissions Scenarios by the Intergovernmental Panel on Climate Change (IPCC). The results of the economic assessments of the impacts of climate change on the agricultural, coastal and marine, energy and transportation, health, freshwater resources and tourism sectors in the Caribbean subregion are presented in Chapters 3 to 9, respectively. The report concludes with an examination of adaptation strategies and key policy recommendations for policymakers, in Chapter 10.

Policy brief: biotechnology with special reference to the Caribbean

The biotechnology movement in the Caribbean is a fledgling industry that has tremendous potential for development. It focuses on the use of fermentation and enzyme technologies, tissue culture and recombinant DNA (rDNA) technology and is more greatly applied to plant varieties rather than animal species. Tissue culture is by far the most developed type of technology but increasing attention is being paid to rDNA technology. Main areas include application in the agriculture sector but the use in medicine and biology are also being promoted. In its purest form, the term "biotechnology" refers to the use of living organisms or their products to modify human health and the human environment for commercial purposes. The term brings to mind many different things. Some think of developing new types of animals while others anticipate almost unlimited sources of human therapeutic drugs. Still others envision the possibility of growing crops that are more nutritious and naturally pest-resistant to feed a rapidly growing world population. Biotechnology in one form or another has flourished since prehistoric times. When the first human beings realized that they could plant their own crops and breed their own animals, they learned to use biotechnology. The discovery that fruit juices fermented into wine or that milk could be converted into cheese or yogurt, or that beer could be made by fermenting solutions of malt and hops began the study of biotechnology. When the first bakers found that they could make soft, spongy bread rather than a firm, thin cracker, they were acting as fledgling biotechnologists. The first animal breeders, realizing that different physical traits could be either magnified or lost by mating appropriate pairs of animals, engaged in the manipulations of biotechnology. Throughout human history, we have learned a great deal about the different organisms that our ancestors used so effectively. The marked increase in our understanding of these organisms and their cell products gains us the ability to control the many functions of various cells and organisms. Using the techniques of gene splicing and recombinant DNA technology, we can now actually combine the genetic elements of two or more living cells. Functioning lengths of DNA can be taken from one organism and placed into the cells of another organism. As a result, for example, we can cause bacterial cells to produce human molecules. Cows can produce more milk for the same amount of feed. And we can synthesize therapeutic molecules that have never before existed.

Exposição humana ao metilmercúrio em comunidades ribeirinhas da Região do Tapajós, Pará, Brasil

Avaliou-se a exposição humana ao metilmercúrio e ao mercúrio total em comunidades ribeirinhas do rio Tapajós e da região metropolitana de Belém, no Estado do Pará, Brasil, através da determinação de mercúrio total e metilmercúrio em amostras de cabelo nos anos de 1994 e 1995. Observou-se que as concentrações médias de mercúrio total variaram de 2 ± 1µg/g-1 a 20,5 ± 12,1µg/g-1, enquanto que as concentrações médias de metilmercúrio variaram de 1,4 ± 0,7µg/g-1 a 18,5 ± 11µg/g-1. Estes resultados confirmam a contaminação mercurial na região do rio Tapajós, admitem a possibilidade do aparecimento de sinais e sintomas de intoxicação mercurial e recomendam a manutenção da monitorização do mercúrio total e do metilmercúrio nas amostras de cabelo, bem como a necessidade de estudos clínico-epidemiológicos para implantação de medidas de prevenção e controle da intoxicação mercurial.
