The potential for more trade by rail between Brazil and its neighbours in the Southern Cone

This edition of the FAL bulletin contains the summary of a review carried out by ECLAC concerning the potential for a higher level of trade via rail between Brazil and other countries of the expanded Mercosur, and through those countries with Asia.At present, such trade occurs at very low levels, except in the case of trade with Bolivia. Some projects are planned, however, that would improve integration of the railway network in the Southern Cone, without requiring very significant levels of investment. If those projects are executed, the prospects would be good in the medium and long term for substantially increasing trade by rail in the region.

The fifth freedom and the Southern Cone: a new perspective

An ECLAC document to be published in the near future examines a subject that has become a frequent topic of discussion in recent years, particularly in the Southern Cone of Latin America (Argentina, Bolivia, Brazil, Chile, Paraguay, Peru and Uruguay), where the greatest volume of land transport in South America is concentrated. Against a background of economic liberalization and integration in the region, and at a time when the development of regional transport infrastructures is growing in importance, the ECLAC Transport Unit analyses the Southern Cone Agreement on International Land Transport (Valparaíso, 1989) in an effort to give it fresh relevance and to determine whether its provisions can cope with the new challenges thrown up by more open international transport markets and management.

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.
