This enormous task would have been impossible to accomplish without this assistance. The WCD secretariat provided guidance to the study team, especially with respect to selection of and the amount of material to be presented in the report. Being an old dam, there is a tremendous amount of information and data available on Kariba. Guidance provided by WCD staff, especially Drs Madiodio Niasse, Bruce Aylward, and Englebertus Oud was valuable in the preparation of a concise report for a broad subject such as the Kariba project. Most of the material relating to Kariba Dam is held in the libraries of the Zambezi River Authority in Lusaka, Kariba and Harare. The consultants are grateful to the Zambezi River Authority (ZRA), through its Chief Executive, Eng. Tumbare, for allowing the consultants free access to their libraries. Their librarians at these three locations, especially Ms Huxtable of Kariba, went out of their way to point out some obscure documents that the consultants would, otherwise, have found difficult to locate. The other source of information on Kariba was the National Archives in both Zimbabwe and Zambia. At both archives, the librarians gladly assisted consultants in accessing critical historical documents. A large amount of historical data on power generated at Kariba and the financial costs thereof, were compiled in this study from records maintained by the Zimbabwe Electricity Supply Authority (ZESA), and the Zambia Electricity Supply Company (ZESCO). The consultants are grateful for the assistance rendered by these two power companies. Most of the literature and debate with respect to Kariba centres on the fate of the 57 000 Tonga people who were displaced by the dam some 40 years ago; and the history of the dam is not complete without the accurate and balanced discussion of this issue. In the course of this study, the sociology consultants spent weeks in discussions with the Tonga people of the Zambezi valley, recording their experiences and their views of Kariba Dam. To these great people, the consultants are grateful. It is hoped that the record of their experiences will provide valuable lessons for similar dam developments in the future, to replicate the good lessons from Kariba and to avoid any negative impacts that Kariba may have had. The draft final version of this report was presented at a meeting of stakeholders at Kariba, 20–22 February 2000, and comments were received on the report from the stakeholders who attended the workshop. In addition, the report was circulated widely to other individuals, NGOs, and other international organisations with interest in the large dam debate. The consultants are grateful to all these organisations and individuals for their comments. Lastly, the consultants are grateful to two reviewers, Professor Saassa, of the University of Zambia and Professor Magadza of the University of Zimbabwe, for editing the first draft of this report. These two learned colleagues have tremendous first hand research experience on Lake Kariba. Their experience greatly improved the content and presentation of the report. However, any outstanding errors and weaknesses in the report are entirely attributable to the consultants. A.
