In the continued quest for increased economic benefits from our water resources, numerous structures and operating policies for controlling the river flow have been built and implemented. These structures and associated operating policies can facilitate navigation; they can provide greater quantities of reliable water supplies to meet agricultural, industrial and municipal water demands; they can generate hydroelectric power and energy; and they can provide increased flood protection, recreation, and other benefits. Over the past half-century we have converted many of our rivers into engineered waterways. These straightened, often periodically dredged, engineered rivers are complete with dikes, reservoirs, weirs, and diversion canals. All this engineering has enhanced economic development. However, as rivers and their floodplains become stressed from the excessive use and misuse of their resources, their contribution to economic development can be threatened. Evidence of economic and ecological degradation, especially in relatively large river systems such as the Danube, the Mississippi, the Rhine, and the Volga, has increased our appreciation of beneficial roles natural aquatic and terrestrial ecosystems play in water quantity and quality management. We have recognized the need to pay more attention to letting nature help us regulate water quantity and quality rather than working against nature and its variabilities and uncertainties. Today there are efforts underway in many developed river basins to 'de engineer' or return these straightened and controlled rivers to a more natural state.

Leading experts present methodologies for basinwide approaches to water quality restoration. In 15 chapters the identification of pollution sources, definition of standards and their attainability, surface and groundwater modeling, remediation of contaminated soils and sediments, development and implementation of low cost treatment technologies, basinwide water quality management and remediation, and economic and institutional issues are covered. The book focuses on the situation in central and eastern European countries; however, the topics and solutions are of general interest and have worldwide applications.

This book is the first part of the Proceedings of the 26th congress of SIL (Societas Internationalis Limnologiae Theoreticae et applicatae) held in Sao Paolo, Brazil in 1994. It contains the papers of all plenary lectures given at that congress. The meeting had the theme ''Water as a limiting resource: Conservation and Management''. Because of the worldwide impact of the issues discussed in the plenary lectures, SIL thought it important to make this unique collection of papers available to the wide audience outside of its organization.

Based on the suggestions made by the speakers of Plenary Session IV “Ch- lenges to the management of water resources and to countering deserti cation in the Mediterranean region” during the 15th Economic and Environmental Forum, the OCEEA proposed to organize a workshop on “Water Scarcity, Land Degra- tion and Deserti cation in the Mediterranean region – Environment and Security Aspects”. In order to build on common synergies, OSCE sought co-operation with c- leagues from NATO, in particular from the Science for Peace and Security P- gramme. NATO has a longstanding expertise on the issue and had organised in Valencia, in December 2003, a NATO scienti c workshop on “Deserti cation and Security in the Mediterranean Region”. The objective of the new proposed wo- shop would be to broaden its focus from the scienti c community to include also policy makers. 1 The workshop, aimed at government of cials from the Mediterranean Region, gathered representatives of Water management, Land degradation and Desert- cation Departments of Ministries of Environment and representatives from the Ministries of Foreign Affairs. In addition, policy makers, scientists and experts were also invited. The aim was to discuss how the OSCE, NATO and other c- petent organizations like the UNCCD, UNEP, MAP, and the EU could play a role in ensuring that environment and security linkages in terms of water scarcity, land degradation and deserti cation are addressed in the Mediterranean Region.

National parks and protected areas offer a wealth of ecological and social contributions or services to humans and life on earth. This book describes the strengths of national parks and protected areas in different parts of Europe and North America and the challenges to the full realization of their goals. It shows that they are useful not only in conserving rare species and biodiversity, but also in protecting water supply and other resources necessary to tourism and to economic and social development generally. Ideas and information on useful planning, management and decision-making arrangements are presented, and research needs are identified.
