Watersheds, supplying crucial ecosystem services to humans, seem to be a logical territorial unit to integrate societal benefits and environmental needs in order to evaluate the sustainability of natural resource use patterns. Based on this belief the book is an attempt to initiate a comprehensive environmental security assessment in the basin of the Azov Sea, shared by Russia and Ukraine. Though the region provides a variety of essential services and plays a strategic role in national and international development plans, it has been excluded from most regional environmental discussions. At the same time there is an alarming degradation rate of basin freshwater ecosystems that has occurred due to overutilization of certain prioritized services (e.g. transportation). The collapse of neglected services (e.g. fishery and freshwater supply) poses serious threats to the national economies as well as the local population, and to mitigate these threats priority in water management should be given to securing sustainability of the regional freshwater ecosystems. In addition to the review of the current status of Azov ecosystem services, the authors analyze likely future availability and challenges. The relevant experience derived from basin management of the Black Sea and other similar basins is also discussed.

The Ural river, the third longest river in Europe, is a unique ecosystem. Unlike other large European rivers the river has not been regulated and the natural hydrological regime is still intact. Thanks to that it has the only remaining spawning habitats in the entire Caspian basin for all sturgeon species. Nevertheless, this fact is not well known to the broader scientific and environmental communities.

The Ural river is also an interesting place due to its rich history of sustainable use of aquatic resources in general and sturgeons in particular. The traditional life style of the local communities, Ural Cossacks, was focused on the preservation and rational use of sturgeon species. This interesting experience of sustainable river-related management is not adequately reported in literature.

To secure further Ural sturgeon preservation the river basin ecosystem and human activities in the region must be managed in an integrated sustainable manner. The sturgeon species can be used as a natural indicator and an incentive for such transboundary IWRM cooperation taking into account all three components of sustainable development: economic, social and environmental. To secure basin IWRM and sturgeon stock restoration the International Ural Sturgeon Park should be established. The role of the Park will be to secure the natural reproduction in the Ural as the primary strategy for the sturgeon stock replenishment. The Ural River Basin Project, which aims at the creation of such a Park, was launched in 2007. This volume is devoted to the uniqueness, history and problems of the Ural river basin, its sturgeons and perspectives of their conservation.
