Über dieses Buch

While almost every aspect of society-nature interactions can be treated as an environmental security issue, the threats to human societies originating from inadequate freshwater management constitute one of the most wi- spread and pressing problems. For thousands of years rivers and river valleys have been the cradle of human civilizations. Rivers have provided not only food and freshwater, but also shelter and means of transportation, and they are still an essential component in every national and regional economy. In turn, growing needs of human societies, accompanied by growing abilities, have caused significant river alterations and ecosystem changes that have resulted in river contamination, biodiversity loss and general riverine ecosystem degradation. The extinction of sturgeon species is one of the most eloquent examples of the negative and irreversible influence of human society on river e- systems. The sturgeon, sometimes called the “living fossil” or living “dinosaur” of the fish world, is known to have lived since the time of the dinosaurs, for at least 250 million years, and is currently on the verge of extinction solely due to anthropogenic impacts.

Environmental Security and the Role of River Regimes in Fostering (Environmental) Cooperation: Case of the International Sava River Basin Commission
Abstract
This paper examines the potential and extent to which international river regimes can serve as a platform for encouraging basin wide environmental cooperation sustainable river basin management and in doing so complement regional stability. Contemporary literature indicates that river water resources are particularly volatile; as such they serve as sources of social instability and posses the power to promote regional stability by strengthening political and fostering environmental cooperation. The research complementing this paper was part of the Master’s dissertation written by the author under the title — “Comparative Approach to Environmental Cooperative Assessment of River Regimes and the Case of the International Sava River Basin Commission.” The results obtained from analyzing four cases of river conflicts — conflicts on the Rhine, Danube, Nile and Jordan Rivers — indicate that even though river conflicts are complex and basin specific, the development of a relationship between stability and river regimes is possible. Accepting such a relationship, the analysis focuses on the recently established International Sava River Basin Commission and more so because the river was under a single jurisdiction for more than half of a century. It questions the regimes credibility to successfully act as a basin-wide administrational and institutional unit, one which practices sustainable water management, without acting as an environmental protection authority and promoting environmental cooperation under the principles of transparency and stakeholder involvement.

Challenges and Prospects of Transboundary Water Management in Eastern Europe, Caucasus and Central Asia
Abstract
Since the breakdown of the Soviet Union in 1990 transboundary water management has become very important in Eastern Europe, the Caucasus and Central Asia (EECCA) since many problems of water protection and use cannot be solved on the national level alone any more. Therefore, most states have taken measures for transboundary water cooperation. However, transboundary water management in the EECCA-region is complicated by many challenges, such as water pollution, lack of data, financial constraints, institutional and structural challenges and shortcomings of concluded agreements. On the other hand, many EECCA-governments are showing increased commitment and interest in transboundary cooperation by allocating additional financial resources, reforming their institutions etc. In addition, various International Organizations and national donors are supporting this trend through capacity-building, funding and other types of assistance.

Successful Transboundary River Basin and Estuary Cooperation: Benchmarks for the Ural River Basin?
Abstract
Russia’s new Water Code means its water resources remain under federal jurisdiction. However, this shouldn’t rule out transboundary water cooperation. After acknowledging the current situation regarding water resources management in Russia, this paper presents three instances of transboundary cooperation, two case studies concerning nations within the Danube basin: the Sava and Tisza sub-basins, and a third concerning the Scheldt Estuary between the Netherlands and Belgium. Some of the challenges and obstacles encountered in ensuring successful transboundary basin cooperation are also presented. The paper concludes by summarizing domestic priorities concerning integrated water management in Russia, in the context of its Volga river and the new Water Code, as agreed by representatives of Russia’s State Duma and envoys of leading international organizations in February 2007. It is hoped this political momentum will provide a foundation for advancing the more effective management of the Ural river basin.

Sturgeon Species

Migratory Fish Stocks in Transboundary Basins — Implications for Governance, Management and Research
Abstract
Migratory fish species move between habitats in order to complete their life-cycles, and are therefore vulnerable not only to fisheries, but also to habitat degradation and loss of connectivity between habitats. In order to conserve migratory fish stocks fisheries must be properly managed, critical habitats maintained and rehabilitated where they have been degraded, and connectivity between habitats ensured. In river basins shared between various countries concerted efforts are needed as impacts in one part of the basin may affect fisheries elsewhere. In inland waters, fisheries compete with different stakeholders and powerful economic interests for access to water resources. Governments are responsible for setting goals for their river basins, elaborate river basins plans and follow up with appropriate legislation in compliance with international agreements e.g. FAO CCRF, Ramsar, CITES and CMS.

The Key Threats to Sturgeons and Measures for Their Protection in the Lower Danube Region
Abstract
The six native sturgeon species have been commercially harvested in the Danube Basin for more than 2,000 years, with rapid decrease in catch by mid 19th century. Additional negative effect on sturgeon populations in the Danube River was river regulation in Djerdap region, due to navigation in the late 19th century, as well as dam construction in the second half of 20th century that blocked sturgeon spawning migrations. Beside over-fishing and habitat loss, illegal trade, life history characteristics of sturgeon, lack of effective management (due to lack of transboundary cooperation and change in political situation in Lower Danube Region countries) and pollution all pose serious threats on sturgeon populations in Lower Danube Region. International measures established by the Convention on International Trade in Endangered Species (CITES) in late 20th century, listing of beluga (Huso huso) as an endangered species under the U.S. Endangered Species Act, as well as development of Action plan for conservation of sturgeons in the Danube River Basin, had significant impact on activities related to sturgeon protection at beginning of 21st century. These actions were aimed towards diminishment of pressure on natural sturgeon populations and aquaculture development in countries of Lower Danube Region. The main goal of the Action Plan was to raise public awareness and to create a common framework for implementation of urgent measures. Black Sea Sturgeon Management Action Group (BSSMAG) was founded as a consultative body to improve transboundary cooperation among countries in Lower Danube Region. Nevertheless, more actions are necessary in the field of basic scientific investigation, NGO involvement and better connection among all stakeholders. Everyone involved in sturgeon protection must be aware that the sturgeon recovery, as well as their extinction, is a multi-decadal affair, especially for species with long life and late maturing like beluga. Resource users and other stakeholders must be patient enough to support recovery plans, which will allow only small-scaled sturgeon fisheries, or even fisheries that will be performed by some future generations.

Rescue Efforts to Save Sturgeons in America
Abstract
The sturgeons — the primary source of commercial caviar, have experienced severe population declines worldwide because of overexploitation, habitat alteration and excessive take for international trade. Some sturgeon species are at serious risk of extinction. The rescue effort to save a declining species of sturgeon in the United States of America (USA) is aimed at using a hatchery to prevent extinction while effective habitat measures are identified and implemented. Recovery is contingent upon re-establishing natural recruitment, minimizing additional loss of genetic variability and successfully mitigating biological and habitat alterations that have harmed the population. A conservation aquaculture program was developed by the Kootenai Tribe of Idaho (KTOI) and has been operating since 1991 to prevent extinction while efforts are made to re-establish suitable habitat conditions to increase natural production. A recovery program 2005–2010 will be presented.

River Rehabilitation: A New Approach to the Design of Fish Passes through Dams
Abstract
Ecosystems of most European rivers were significantly altered by human activity throughout the 20th century with the aim of facilitating economic development and settlement protection. The ecosystem needs and environmental flow requirements were neglected, which resulted in river ecosystem degradation and biodiversity loss. As a rule, river rehabilitation programs are costly and complicated processes. While aiming at overall river ecosystem rehabilitation, recently initiated restoration programs should take into account regional peculiarities and specificities. One of the relatively cheap and easy technologies to deal with some aspects of river rehabilitation and securing environmental flow needs is suggested. It is based on restoration of the migration routes for the most sensitive and vulnerable river basin species: migratory fish, such as sturgeons. The existing fish passing facilities in South Russia are inefficient and require urgent replacement. The proposed technologies for fish passage through the dams and barrier complexes are based on the “non-forced” principle, unlike the predominant 20th century approach to fish transfer.

The Ural River Basin: Hydrology, Characteristics and Water Use
Abstract
The Ural river is a unique ecosystem with a mostly undisturbed hydrological regime and is crucial for the preservation of the Caspian sturgeon species. This is the third longest river in Europe and the last large river in Europe unaffected by river regulation or damming. Nevertheless, this fact is not well known to the broader scientific and environmental communities (UNEP 2002). The present paper gives an introduction to the Ural river’s hydrology, climate, land use types and other basin characteristics. An analysis of the river flow statistics, human activities’ influence and regional climate change is undertaken. The administrative watershed division and the problems of transboundary water management are also discussed.

River Flow Formation in the Russian South Urals
Abstract
Features of small rivers’ flow formation in the Orenburg region of Russia are analyzed. The flood flow dynamics of the small rivers of the South Urals are presented, in relation to changes in the system of agricultural land tenure in the period 1936–1995. Consideration is given to how the balance of water from melted snow on the slope is influenced by relief shapes and holding types, and an estimate of the impact of winter tillage on the melted snow flow factor is provided.

Climate Change and Water Resources in North Caucasus and South Urals
Abstract
While previous studies have focused on impacts of average climate change on food production and water resources, this study takes into account the impact of changing frequency and spatial heterogeneity of extreme climate events, first of all, droughts. We analyze impacts of the IPCC A2 and B2 climate scenarios with the use of the GLASS model (containing the GAEZ crop production model and the WaterGAP water resources model). We evaluate future risk of extreme climatic events for food production and water availability for two important regions of Russia — North Caucasus and Urals. Under climate normal conditions it is estimated that “food production shortfalls” (a year in which potential production of the most important crops in a region is below 50% of its average climate normal production, taking into account production in food exporting regions) occur roughly one to three years in each decade. This frequency will double in the both regions in the 2020s, and triple in the 2070s. The assessment of climate impacts on water resources indicates an increase in average water availability in Russia, but also a significantly increased frequency of high runoff events in much of central Russia, and more frequent low runoff events in the South. Unlike the food production, the situation with water resources looks very different for North Caucasus (Kuban and Don river basins) and Urals (Ural river basin) regions. The results suggest the increasing threat to the water resource of the North Caucasus and more stable water flow in the Urals in the new climate.

The Ural River Sturgeons: Population Dynamics, Catch, Reasons for Decline and Restoration Strategies
Abstract
The Ural river, the third longest river in Europe, has the only remaining spawning habitats in the entire Caspian basin for all sturgeon species. Unlike other large European rivers the river’s ecosystem has not been altered and the natural hydrological regime is still intact. The Ural sturgeon yield-to-fishery relative to river discharge was the highest in the Caspian Sea till recently. The environmental conditions to secure natural reproduction are still satisfactory for successful sturgeon reproduction. However, nowadays the catch in all regional sturgeon species is negligible. The Ural sturgeon population dynamics are analyzed along with some anthropogenic and natural factors affecting them. It is argued that legal overfishing (including all legal means of fish removal), based upon (a) faulty estimations of sturgeon stock and catch limits and (b) inappropriate fishery policies are the principal reasons for the stock decline in the Ural. The maintenance of the natural reproduction in the Ural is considered to be the primary strategy for the stock replenishment. If used at all, artificial propagation should be used only as an additional secondary option exclusively at the historical sturgeon habitats upstream the Ural river and not in the river delta, where the hatcheries are located now. Transboundary cooperation of basin countries with active international involvement is essential to prevent further deterioration of the situation.

Field and Genetic Approaches to Enhance Knowledge of Ural River Sturgeon Biology
Abstract
Combined approaches utilizing tagging and genetic analysis can provide powerful insight into the biology and management of endangered sturgeons as described in a literature review herein. Since 2003, our team of USA and Republic of Kazakhstan researchers has attempted to use such techniques to study Ural River sturgeons. High-tech (satellite, acoustic) tagging methods were to be applied to examine movement and behavior of Ural River sturgeons within the River and the Caspian Sea and test hypotheses about sturgeon biology. In 2006, we successfully completed a satellite tagging project in which four adult sturgeons (three beluga, Huso huso, and one ship sturgeon Acipenser nudiventris) captured in the Ural River were equipped with Pop-up Archival Transmitting (PAT) satellite tags and released into the Caspian Sea. In 2007, efforts were made to initiate an acoustic tagging and tracking program within the Ural River to study sturgeon migratory behavior and locate spawning grounds. Tagging has also been used to measure the contribution of hatchery-produced sturgeons to that of the wild population. These studies were to be combined with genetic approaches to study the uniqueness and diversity of Ural River sturgeons. Overall, our program produced mixed results: some projects could not be undertaken, others produced only preliminary results, and some initiated long-term monitoring. Our work has implications for the conservation of Ural River sturgeons.

Fish Biodiversity of the Orenburg Region and Their Parasitic Diseases
Abstract
The problem of fish parasites threatening the food fish populations and, consequently, human health is an important aspect of water related environmental security. Analysis of the research results shows alarming parasitological situation with food fish populations in the Orenburg reservoirs. The fish parasites with various epidemiological values were found. Based on the research conducted for the last five years, it can be concluded that the fish parasitic fauna in the regional ponds is not fully investigated. Further research is needed to collect the data and plan rehabilitation programs.

Restoration Activities

Establishment of the International Ural Sturgeon Park to Secure Sturgeon Conservation and to Facilitate Sustainable Integrated Water Management
Abstract
The only free-flowing river in the Caspian basin, the Ural River, is a unique ecosystem with a preserved natural hydrological regime and the last remaining in the Caspian basin unaltered sturgeon spawning habitats. To secure its further preservation the river basin ecosystem and human activities in the region must be managed in an integrated sustainable manner. Though there is now an international consensus on the need for an integrated approach to sustainable river basin management, there is no standard definition of the term “sustainable” or consensus on how to reach this state. Sustainable development of watersheds should consider three main components: economic, social and environmental, which can hardly be reached in real-life watershed management. Using sturgeon species as a natural indicator and an incentive for transboundary IWRM cooperation in the Ural river basin is suggested. To secure basin IWRM and sturgeon stock restoration the Ural River Sturgeon International Park should be established. The Ural River Basin Project, which aims at the creation of such a Park, is described in this paper. Activities towards successful integrated water management in the Ural Park will not only work towards sustainable watershed management, but also secure preservation and restoration of sturgeon. Local communities (Cossacks) involvement in sturgeon conservation and water management also resolves social and economic problems by restoration of the traditional life style.
