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. Ralph J. Cicerone 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 was 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. Ralph J. Cicerone and Dr. Wm. A. Wulf are chairman and vice chairman, respectively, of the National Research Council.

PREFACE

During the 2002 World Summit on Sustainable Development (WSSD), the U.S. National Academies, the U.S. Environmental Protection Agency, and the American Chemistry Council announced a new initiative to facilitate better communication among scientists, policymakers, and other decision-makers so that scientific knowledge more effectively informs public policy and private sector decisions relating to sustainability in developing countries. More specifically, the goals of the initiative are:

  • Foster improved understanding of the science and decision-making process, including national and local policy, industrial design and planning, and public choices;

  • Establish dialogue in which decision-makers use science to inform their decisions and scientists consider the needs of decision-makers in their choice of research;

  • Identify gaps between the needs of decision-makers and scientific research priorities and strategies for bridging these gaps, including ways to increase the professional connection between scientists and decision-makers, and;

  • Share workshop results, via summaries and briefings, with a broader audience of scientists and decision-makers in the host country and internationally.

To achieve these objectives, the organizations involved (see list below) provided support for a series of "science in decision-making workshops" in developing countries on key issues of particular concern to the host country such as water and sanitation, persistent organic pollutants, and biodiversity. The workshops convene representatives from host country and U.S. scientific institutions, government, industry, non-governmental organizations, academic institutions, and other relevant organizations. Crosscutting themes addressed in the workshops include monitoring and data evaluation; elements of good science advice; facilitating the flow of scientific information; and the roles of institutions that link scientists and decision-makers.


Workshop topics are proposed by science organizations in developing countries. A steering committee established by the U.S. National Academies reviewed proposals and provided general oversight for the series. The workshop co-chairs– one from the respective developing country and one from the United States – designed each workshop, which were organized in a collaborative process involving the U.S. National Academies and one or more science organization from the partnering country.


The initiative involved the following organizations:

  • U.S. National Academies

  • Mexican Academy of Sciences

  • Chinese Academy of Sciences

  • TWAS, the Academy of Sciences for the Developing World

  • InterAcademy Panel

  • American Chemistry Council

  • U.S. Environmental Protection Agency

  • Scientific Committee on Programs of the Environment, China

  • H. John Heinz Center for Science, Economics, and the Environment

  • National Council for Science and the Environment

  • State Environmental Protection Administration of China

The initiative’s first workshop, “Strengthening Science-Based Decision-Making for Sustainable Management of Ground Water in Mexico,” was a joint workshop between the U.S. National Academies and the Mexican Academy of Sciences. It was held February 8-10, 2004, in Mérida, Mexico. The second workshop, “Strengthening Science-Based Decision Making –Implementing the Stockholm Convention on Persistent Organic Pollutants” was held June 8-10, 2004, in Beijing, China. The third workshop titled “Strengthening Science-Based Decision-Making for Agricultural Water Management.” took place June 4-9, 2005, in Tunisia and is featured in this report.


The Tunisia workshop was co-chaired by Dr. Henry Vaux, Jr. of the University of California, Berkeley, and Dr. Sihem Benabdallah, of the Institut National de Recherche Scientifique et Technique in Tunisia. The meeting involved approximately 30 attendees from Tunisia, other Organization of the Islamic Conference (OIC) countries, and the United States, including decision-makers from both the public and private sectors, and scientists from relevant disciplines, such as agronomy, economics, and natural resource management. The overarching question considered at the workshop was: How can Tunisia and other countries in the region marshal their considerable bodies of scientific talent to address the problem of insufficient agricultural production caused by water scarcity? The workshop also addressed two major sub-issues related to food production. First, how can existing water supplies, including recycled waste water, be managed so as to optimize the domestic production of food and fiber? Second, what can the public and private sectors do to optimize production of high value agricultural products? Discussions of these issues included: information about scientific advances in irrigation; suggestions regarding communicating this information to the appropriate decision-makers; consideration of additional information that decision-makers need; and comments regarding what organizations are or should be involved in facilitating the flow of such information.


The workshop began in Tozeur with a field trip to observe Tunisian agriculture and agricultural management practices. The field trip participants, including almost all of the international and U.S. participants and several Tunisians, observed groundwater mining to produce dates, mangos, and other high-value crops; wastewater reuse experiments; oasis agriculture practices; erosion prevention systems; hothouse agriculture; and other agriculture and water management systems. Discussions at various sites revealed concerns about salinity, sustainability of the system (with groundwater levels declining rapidly), security implications of drawing down a shared aquifer, and the vulnerability to drought of the populations in the region.


The papers included in this volume were submitted by the participants to help frame these discussions. As such, many of the papers do not include the technical detail or exhaustive citations found in a scientific journal. The opinions expressed in the papers do not necessarily reflect the views of all workshop participants, their affiliated organizations, or the National Academies. The report does not contain consensus findings or recommendations from the workshop participants as a whole.
