Emerging Consequences Of Biotechnology

The principal message of this book is that thermodynamics and statistical mechanics will benefit from replacing the unfortunate, misleading and mysterious term "entropy" with a more familiar, meaningful and appropriate term such as information, missing information or uncertainty. This replacement would facilitate the interpretation of the "driving force" of many processes in terms of informational changes and dispel the mystery that has always enshrouded entropy. It has been 140 years since Clausius coined the term "entropy"; almost 50 years since Shannon developed the mathematical theory of "information"--Subsequently renamed "entropy." In this book, the author advocates replacing "entropy" by "information," a term that has become widely used in many branches of science. The author also takes a new and bold approach to thermodynamics and statistical mechanics. Information is used not only as a tool for predicting distributions but as the fundamental cornerstone concept of thermodynamics, held until now by the term "entropy." The topics covered include the fundamentals of probability and information theory; the general concept of information as well as the particular concept of information as applied in thermodynamics; the re-derivation of the Sackur-Tetrode equation for the entropy of an ideal gas from purely informational arguments; the fundamental formalism of statistical mechanics; and many examples of simple processes the "driving force" for which is analyzed in terms of information.

Assuring food security for the next 25 years requires meeting a number of political, social, economic, and technical challenges. One of these is the successful use of new biotechnologies in agriculture. Research in recombinant genetics and biotechnology aims to develop plant varieties that provide reliable high yields at the same or lower costs by breeding in qualities such as resistance to disease, pests, and stress factors such as aridity. Realization of these goals could lead to tremendous gains in food production. However, biotechnology is now evoking the same objections that have been raised against the Green Revolution—that its benefits are distributed inequitably in favor of the large, rich farmers and that it is potentially environmentally destructive. In this brief, Leisinger discusses the need for biotechnology and its sociopolitical ramifications and he looks at the roles played by the public and private sectors. In conclusion, the author states that biotechnology offers no silver bullet for food security — there are no silver bullets—but biotechnology is an important instrument in the difficult fight against hunger. The sociopolitical obstacles must be removed not only for the successful implementation of biotechnology, but also for an equitable and sustainable tomorrow for the world.

In the context of South Asian Association for Regional Cooperation countries.

Many developing countries are exploring whether biotechnology has a role in addressing national issues such as food security and environmental remediation, and are considering whether the putative benefits of the technology-for example, enabling greater agricultural productivity and stability in the food supply-outweigh concerns that the technology might pose a danger-to biodiversity, health, and local jobs. Some policy leaders worry that their governments are not prepared to take control of this evolving technology and that introducing it into society would be a risky act. Others have suggested that taking no action carries more risk, given the dire need to produce more food. This book reports on an international workshop held to address these issues. Global Challenges and Directions for Agricultural Biotechnology: Mapping the Course, organized by the National Research Council on October 24-25, 2004, in Washington, DC, focused on the potential applications of biotechnology and what developing countries might consider as they contemplate adopting biotechnology. Presenters at the workshop described applications of biotechnology that are already proving their utility in both developing and developed countries.

Dealing with the challenges presented by climate change or rapid urban development require cooperation and expertise from engineering, social and natural sciences. Earth systems engineering is an emerging area of multidisclinary study that takes a holistic view of natural and human system interactions to better understand complex systems. It seeks to develop methods and tools that enable technically sound and ethically wise decisions. Engineering and Environmental Challenges presents the proceedings of a National Academy of Engineering public symposium on Earth systems engineering.

Transgenic crops offer the promise of increased agricultural productivity and better quality foods. But they also raise the specter of harmful environmental effects. In this new book, a panel of experts examines: • Similarities and differences between crops developed by conventional and transgenic methods • Potential for commercialized transgenic crops to change both agricultural and nonagricultural landscapes • How well the U.S. government is regulating transgenic crops to avoid any negative effects. Environmental Effects of Transgenic Plants provides a wealth of information about transgenic processes, previous experience with the introduction of novel crops, principles of risk assessment and management, the science behind current regulatory schemes, issues in monitoring transgenic products already on the market, and more. The book discusses public involvementâ€"and public confidenceâ€"in biotechnology regulation. And it looks to the future, exploring the potential of genetic engineering and the prospects for environmental effects.
