This scoping paper considers the interrelationship between the fisheries and the protection of the marine environment of the Caspian Sea.  It has been prepared in response to the request of the Parties to the Convention on the Protection of the Marine Environment of the Caspian Sea, during the first meeting of Conference of the Parties in May 2007 in Baku.[1]  The aim of the scoping paper is to support the Parties in their efforts to intensify their regional dialogue and to build their regional partnership for safeguarding the marine environment of the Caspian Sea for the benefit of present and future generations.

There no evidence that reduction in fish populations is the only possible cause of decline in tulka catch. Availability of existing stocks to fishery industry could be another immediate cause of decline in catches. This cause is more difficult to exam as little data is available on stocks relocation and changes in fish behaviour.

Decline of stock is reported and is considered as the most important factor. At the moment it is the only immediate cause possible to exam with sufficient data. It has several underline causes and each cause can has different impact to three species. According to Astrakhan Fishery Institute data stock of anchovy tulka reduced from 968 thousands tons in 1999 to 300 thousands tons in 2002, stock of big-eye tulka reduced from 112 thousand tons in 1999 to 4 thousands tons in 2004; and stocks of Caspian tulka remain in stability at the level of 400 thousands tons.

The Caspian Sea, world largest lake, is bordered by Azerbaijan Republic, Islamic Republic of Iran, Kazakhstan, Republic, Russian Federation and Turkmenistan. Its biodiversity is comprised of 1354 plant, animal and more than 122 fish species. Out of 122 fish species and subspecies living in the Caspian Sea, 40 species are commercial and presently 25 species are the main exploited fish. The Caspian Sea fishes are divided to four main groups, including 53 species Marine fishes (43.5%), 42 species (13.4%) of freshwater origin, 18 species (14.7%) anadromous and 9 species (7.4%) semi-anadromous. At present sturgeons, kilka and Caspian Sea seals are considered as shared stocks between Caspian Sea range states.

The present report on the State of the Environment of the Caspian Sea was developed in accordance with the requirements of the Framework Convention for the Protection of the Marine Environment of the Caspian Sea (Tehran Convention, 2003) and is one of the regional environmental cooperation mechanisms to assess the state of the marine environment of the Caspian Sea, in particular, pollution and its impact, based on the reports provided by the Contracting Parties and any competent international organization.

The Caspian Sea, abundant with natural living and fossil resources, its coastal areas home to more than 15 million people, faces a series of environmental challenges.

This State of the Caspian Sea Environment Report should be seen and considered as a first try out and starting point towards the creation of a shared environmental information system promoting and securing data collection, monitoring, analysis, harmonization and public communication in support of full implementation of the Tehran Convention and its protocols. We hope that it will improve the Caspian information base, enhance the quality, accessibility and relevance of data and ultimately, contribute to strengthening the regional environmental governance framework.

Review of Kazakhstan's activities in fulfillment of obligations under the Tehran Convention

The article examines recent Caspian Sea level change by using both satellite radar altimetry and satellite gravity data. The altimetry record for 2002–2015 shows a declining level at a rate that is approximately 20 times greater than the rate of global sea level rise. Seasonal fluctuations are also much larger than in the world oceans. With a clearly defined geographic region and dominant signal magnitude, variations in the sea level and associated mass changes provide an excellent way to compare various approaches for processing satellite gravity data. 

The CEP TDA Revisit was completed in December 2007 following an intensive desk study of materials collected from the second phase of the Caspian Environment Programme. The intention of the CEP TDA Revisit is to provide a follow on review of the priority transboundary issues, to assess the efforts conducted during the CEP Phase II implementation, and to extrapolate where additional efforts are warranted. The SAP and NСAPs are reviewed followed by an analysis of the priority areas of concern as identified in the SAP. The issues addressed in the TDA are: decline in biodiversity; decline in environmental quality (pollution); decline in bioresources (fisheries); decline in coastal infrastructure and habitat; and impacts of the oil industry in the region. This is supplemented by an analysis of governance mechanisms, socioeconomic conditions in the region, and stakeholder analysis and public involvement strategy.

This volume aims to provide background information on the Caspian Sea in order to support the recommendations in the National Caspian Action Plans (NCAPs) and the Strategic Action Programme (SAP). Thus, this TDA is not merely a State of the Environment report, but also a look into the future based on the current political situation, socio-economic conditions, and legal/regulatory framework. 

This TDA relies on and benefits from the dedicated work of numerous individuals, agencies, institutes, projects and corporations. The major building blocks are the studies and research works conducted and
carried out by the Caspian Regional Thematic Centres. These works have been mostly produced by the national experts of the Caspian countries and have been effectively led and substantially assisted by the National Focal Points (NFPs) and the Management Advisory Group and Inter-sectoral Assistants (MAGICAs). Production of the TDA would have not been possible without the efficient project execution assistance of UNOPS. The overall conceptualization, design, production monitoring and editing of the TDA has been led by the Programme Coordination Unit (PCU) including the Data and Information Management Theme in Baku, Azerbaijan.

This study is an attempt to develop an integrated methodology to predict the impact of the Caspian Sea on flooding using Geographic Information Systems (GIS) and hydrodynamic modeling. A rise in the sea level might lead to major flooding events, and have a severe impact on the spatial development of cities and regions. The feasibility of simulating a flood event along a drain channel is evaluated near residential development areas along the Chapakroud drain.

The study shows that at these elevations environmental and social problems arise with regards to the drain. The results also indicate that GIS is an effective tool for floodplain visualization and analysis. It should be noted that the mixture of salt and soft water, as a result of rising sea water level, is a problem that was not investigated in this study and should be examined in the future.
