Printed on acid-free paper Springer is part of Springer Science+Business Media (www.springer.com) Foreword In 1989, growing concern about the destruction of tropical ecosystems and the need to improve the living conditions of local populations in Amazonia and the cerrado led Brazilian and German politicians and scientists, during the annual meeting of the Joint Commission, to expand and intensify the already existing bilateral cooperation in the field of ecology. The efforts aimed to achieve the following common interests: (1) develop concepts for the sustainable use and protection of tropical ecosystems, (2) solve or diminish already existing environmental problems, (3) consolidate or expand already existing facilities for developing tropical ecology research, and (4) promote scientific collaboration through joint research projects and training. The partners selected the following geographic regions and research projects: (1) the forests and floodplains in the Amazon basin, (2) the forests of the coastal region (Mata Atlântica) and its inland waters, and (3) the floodplain of the upper Paraguay River (Pantanal) and its catchment area. The resulting program, entitled Studies of Human Impact on Forests and Floodplains in the Tropics (SHIFT), became established within the framework of the special agreement on cooperation in the field of environmental research and technology between the Instituto Brasileiro do Meio Ambiente e Recursos Renováveis (IBAMA) and the Deutsche Forschungs- und Versuchsanstalt für Luft- und Raumfahrt e.V. (DLR). In 1992, the Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) took the position of leadership of the Brazilian side, participating in the project’s financing. In light of the multiplicity of factors contributing to the impact of the study biomes, including those of anthropogenic origin, the different levels of available knowledge, infrastructure, and human resources, and the need for urgent actions, the SHIFT Program, from its beginning, opted for a highly pragmatic approach. It aimed at: (1) a description of the dimensions of human impact, (2) an analysis of the reasons underlying these anthropogenic effects, (3) the elaboration of proposals to mitigate the negative side effects of human action, and (4) the development of new methods for sustainable management, taking into consideration the specific ecological, economical, social, cultural and political conditions of the individual study biomes and ecosystems. To reach these goals, multidisciplinary and interdisciplinary studies and a multi- institutional approach were recommended, in a combination of investigations into v vi Foreword terrestrial ecology, limnology, agriculture, forestry, fishery, animal husbandry, soil science, climatology, and environmental technologies, as well as socio-economy, regional planning, and resource management. Logistic and scientific basis for the research projects in the Amazon River flood- plains was the successful cooperation between the National Institute for Amazon Research (INPA) in Manaus, and the Max-Planck Institute for Limnology (MPIL), Plön that was established in 1962 by Prof. Djalma Batista and Prof. Harald Sioli. The new projects were realized under the coordination of Dr. Maria Teresa Fernandez Piedade of INPA and Prof. Dr. Wolfgang Junk, head of the Working Group of Tropical Ecology at MPIL. INPA provided laboratory space, and BMBF, CNPq, and MPIL improved the projects’ infrastructure with equipment, financed scholarships, travel expenses, and consumables of the projects. The scientific results have been published in more than 600 scientific articles, book chapters, and reports. Numerous Ph.D., M.Sc. and Bachelor theses were written by students involved in the program. In 2000, the first book was published (Junk, W.J., Ohly, J.J., Piedade, M.T.F., and Soares, M.G.M., (eds): The Central Amazon Floodplain: Actual Use and Options for a Sustainable Management. Backhuys Publishers, Leiden: 584pp). The analyses of the already published material showed big gaps in the knowledge of ecophysiology, biodiversity and sustainable management of the floodplain forest, and since 1997 the field work concentrated on this subject. In 2002, an independent joint scientific commission analyzed the program and recommended its continuation for three more years in order to finalize the projects and elaborate praxis-oriented solutions. However, a change in both the Brazilian and the German political leadership led to the abrupt end of SHIFT, placing at risk the many fruits of this successful cooperation. With the support of their institutions, a strong will and even personal resources, the program’s leading scientists managed to continue the work, even though on a much smaller scale, thus avoiding major losses of scientific results, infrastructure, and human resources. In August 2003, a cooperation contract with the Mamirauá Institute for Sustainable Development was signed. In 2005, the research project in the Mamirauá Reserve was selected as a Demonstration Project of UNESCO’s Ecohydrology Programm (IHP). In 2006 the research group initiated a project financed by the CNPq to support “research to develop a sustainable community-based management of floodplain forests in the Amanã and Mamirauá Reserves”. In 2007, the team received funding of a project in the Brazilian research initiative “Nucleus of Excellence Projects” (PRONEX), supported by CNPq and Amazonas State Science Foundation (FAPEAM). The main goal of this project is to typify the wetlands of the Amazonas State, only possible owing to the accumulated information of the team during the past decades. Other two projects were approved in 2008 by CNPq, supporting studies on the impact of climate change on species shifts and diversity losses of Amazonian floodplain vegetation. The increasing drive in wetland research in South America culminated with the realization of the eighth INTECOL Wetland Conference in 2007 in Cuiabá, Brasil, and led to the elaboration of this book. It summarizes the major findings of the SHIFT Program and reviews the recent results of research activities about floodplain Foreword vii forests in Central Amazonia regarding distribution, ecology, primary production, ecophysiology, typology, biodiversity and use. Importantly, it offers recommenda- tions for sustainable management and future projects in science and development of the Amazon floodplain forests. This is the first integrative book on the functioning and ecologically oriented use of floodplain forests in the tropics and sub-tropics. It provides a solid scientific basis for wetland ecologists, foresters, environmentalists, and wetland managers. It is also an excellent textbook for students working in Amazonian floodplain forests and similar forest types in other regions. The authors have worked for many years in the Amazon basin and have a profound knowledge of the subject. They interpret their findings under an integrating scientific concept, the Flood Pulse Concept. On behalf of the coordinators of the research projects and the coeditors of this book I gratefully acknowledge the financial support of the CNPq, BMBF, Max- Planck-Society and Amazonas State University (UEA), and the infrastructure provided by INPA, MPIL and Mamirauá Reserve especially Dr. José Márcio C. Ayres (in memoriam), and Helder Lima de Queiroz. We gratefully acknowledge the support of Prof. Dr. José Galicia Tundisi, president of CNPq from February 1995 until December of 1998, and his collaborators Dr. Carlos Roberto de Faria e Souza, Dr. Glauter Pinto de Souza and Dr. Gilvan Marcelino. Our special thanks go to Ms. Izaura Matiko Yamada, analyst in science and technology of CNPq, who gave substantial help in all bureaucratic aspects. On the German side we gratefully acknowledge the help of Dr. Günther Keil from BMBF, Dr. Emil Stüttgen from KFA Jülich, Dr. Helmut Bianchi from GKSS Geesthacht, and Dr. Klaus Matthes, from 1990 to 1995 scientific attaché of the German Ambassy in Brasilia. Our special thanks go to our technicians and field workers, mainly Celso Rabelo Costa, Valdeney de A. Azevedo, Conceição Lúcia Maia Costa, Edivaldo de Souza Ferreira, Wallace Rabelo Costa, Agenor Negrão da Silva, and Mario Picanço in Manaus, Jackson de Castro and Emilson José Pereira Tiburcio in the Mamirauá Reserve, and Uwe Thein (in memoriam), Stephanie Barthel, Elke Bustorf, Berit Hansen, Gerda Lemke and Sabine Meier in Plön. Without their knowledge, field and laboratory experience and enthusiasm, these studies would not have been performed at this high level. Plön, Germany, spring 2009 Wolfgang J.
