THE NATIONAL ACADEMIES Advisers to the Nation on Science, Engineering, and Medicine The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Bruce M. Alberts is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Wm. A. Wulf is president of the National Academy of Engineering. The Institute of Medicine as established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine. The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Bruce M. Alberts and Dr. Wm. A. Wulf are chairman and vice chairman, respectively, of the National Research Council. www.national-academies.org

Preface The U.S. National Committee for CODATA collaborated with the Senegalese National CODATA Committee to convene a Workshop on Scientific Data for Decision Making Toward Sustainable Development: Senegal River Basin Case Study, which was held on March 11-15, 2002, in Dakar, Senegal. This workshop examined, on a multidisciplinary level, data sources and data handling in the West Africa region, using the Senegal River basin (in Senegal, and in the bordering countries of Mali, Mauritania, and Guinea) as a case study, to determine how these scientific and technical data assets are or can be better managed and used in decision making related to sustainable development. An organizing committee consisting of eight members representative of the expertise and experience required, four from the United States and four from Senegal, planned the workshop. This organizing committee was cochaired by Abdoulaye Gaye, chair of the Senegal National CODATA Committee, and William Jobin of Blue Nile Associates. Areas of expertise that were not covered by this committee were augmented by additional workshop attendees. The organizing committee developed the workshop agenda, prepared for the meeting and related logistics, and selected and invited all the meeting attendees. The U.S. National Committee for CODATA had the responsibility for publishing the workshop summary and disseminating the report. The workshop included researchers and data managers from the United States, Senegal, and other African countries who have collected, managed, and used data regarding the Senegal River basin. The meeting helped identify local and foreign data resources related to the ecology and environment of the Senegal River system in West Africa, and to the related health and economic activity of the populations. In the Senegal River basin, for example, scientists have been considering issues such as the hydrology and environmental impact of the new dams (Diama and Manantali), biodiversity and ecosystem assessments, protection and use of natural resources, and the monitoring and improvement of the health of the local population. A considerable amount of remote sensing, aerial,

and in-situ data already has been collected and archived for this region, so it provides a robust example of what has been done in one region of the developing world, as well as what might be done in the future. The workshop provided U.S. federal government and academic data experts and researchers with an inside view of African science and technology data programs and an opportunity to initiate collaboration in various related areas. Prior to the workshop there was a one-day site visit to the Diama Dam on the Senegal River, as well as to the Organisation pour la Mise en Valeur du Fleuve Sénégal (Senegal River Authority) Regional Documentation Center and the Université Gaston Berger, both in Saint-Louis, Senegal. Many of the research activities and training opportunities related to the Senegal River basin are conducted at the university. There was a half-day site visit the following day to the Centre de Suivi Ecologique (Ecological Monitoring Center) in Dakar, which develops, archives, and manages most of the country’s ecological and environmental data and information resources. It is hoped that this workshop contributed to the capabilities for sustainable development in West Africa by identifying and reviewing scientific data activities that could help managers in different sectors, policy makers, and citizens to make better-informed decisions about the Senegal River basin area. The workshop and this resulting publication are intended to foster communication and interaction among a number of interested groups at the local and regional levels. The primary audience includes scientists, data managers, educators, and senior decision makers from the government, nongovernmental organizations, and industry sectors who are working in Senegal and the West African region, as well as their counterparts in the United States who have similar interests in that area. A secondary but also very important audience includes similar categories of individuals in other African nations and in other developing countries outside Africa who are concerned with using scientific data for improved decision making in sustainable development activities, particularly relating to river systems. This report also is available online via the National Academies Press Web site, and includes hyperlinks where available to organizations and data sources identified during the course of the workshop. Links to individual workshop presentations where available can be found through the U.S. National Committee’s Web site at http://www7.nationalacademies.org/usnc-codata/Senegal%20Workshop.html and on the Senegal National Committee’s Web site at http://www.codata.sn/16conf.htm.
