This book analyses the importance of maize worldwide and the special importance for Mexico as a centre of origin and diversity (COD). By adopting a comparative approach, the analysis focuses on how developed and developing countries handle imports of Genetically Modified Organisms (GMO & rsquo;s). It also analyses the impact that GM maize imports from the USA may have in Mexico as COD of maize. This book illustrates the process of economic liberalization in Mexico from the 1980 & rsquo;s until the inception of the North American Free Trade Agreement (NAFTA) in 1994. It provides a descriptive and analytical insight into the Mexican legal framework of biotechnology and biosafety. Finally, it outlines the problems of complying with both environmental, and trade commitments.

On October 14-19, 1990, the 6th International Conference on the Conservation of Earthen Architecture was held in Las Cruces, New Mexico. Sponsored by the GCI, the Museum of New Mexico State Monuments, ICCROM, CRATerre-EAG, and the National Park Service, under the aegis of US/ICOMOS, the event was organized to promote the exchange of ideas, techniques, and research findings on the conservation of earthen architecture. Presentations at the conference covered a diversity of subjects, including the historic traditions of earthen architecture, conservation and restoration, site preservation, studies in consolidation and seismic mitigation, and examinations of moisture problems, clay chemistry, and microstructures. In discussions that focused on the future, the application of modern technologies and materials to site conservation was urged, as was using scientific knowledge of existing structures in the creation of new, low-cost, earthen architecture housing.
