This paper examines the major environmental problems affecting the Caspian Sea region, with particular focus on water pollution, ecosystem degradation, and the decline of sturgeon populations. It outlines how industrial discharge, agricultural pesticides, oil extraction, and untreated sewage have severely compromised the region's ecology. The paper also addresses how political fragmentation following the collapse of the Soviet Union has hindered coordinated environmental action. Drawing on comparisons with the North American Great Lakes cleanup, the paper argues that an internationally monitored, integrated remedial plan — alongside genuine political cooperation among the five bordering states — is essential to reversing the ongoing environmental crisis in the Caspian region.
There has been considerable growth in interest and concern about the global environment during the past decade. Governments, policymakers, and environmental bodies are becoming more involved in addressing problems such as pollution and unmanaged ecosystems. This concern has been further heightened by the scientific community's acceptance of the reality of global warming and climate change, which has been almost certainly linked to human causative factors such as carbon dioxide emissions into the atmosphere. These concerns have refocused attention on various problem areas around the world.
There are numerous environmental problems that merit discussion. Among these is the importance of ozone emissions. As one study indicates, "Such issues could be global in cause (the burning of fossil fuels) or they could be global in effect (again, fossil fuel burning, ozone depletion) or both" (Glantz, 1999). A wide range of issues affect the global environment, including desertification, acid rain, water and air pollution, biodiversity loss, coral bleaching, and tropical deforestation — all of which have global ramifications. However, certain world regions are more severely affected by environmental problems than others, with long-term implications for the entire planet. One of these areas is the Caspian region.
The Caspian region is an area affected by a number of serious environmental issues. Like so many localized and regional problems, although they are confined to a certain area, they have the potential to affect global issues. The Caspian Sea is described as the "largest inland body of water on the planet, with a surface area of 384,400 km², a volume of 78,700 km³, and a coastline nearly 7,000 km long. It measures 1,200 km from north to south and 200–450 km from east to west" (Glantz, 2000). Today, five countries border the Caspian Sea: the Russian Federation, Azerbaijan, Iran, Turkmenistan, and Kazakhstan. Much of the sea is fed by the Volga River, situated in territory belonging to the Russian Federation. This river also creates one of the central problems in the area, as pollution carried by the Volga flows directly into the sea.
The problem of pollution in the sea has further environmental implications in that the sea is a major breeding ground for sturgeon fish (Glantz, 1999). This and other related problems have caused the Caspian region to be described as an "ecocatastrophe." Smirnov (2001) states that "The Caspian Sea is an example of an ongoing large-scale ecocatastrophe (partly a result of natural causes) as well as an example of political disagreements and a temporary legal vacuum, which followed the collapse of the Soviet Union" (Smirnov, 2001).
Before the collapse of the Soviet Union, the Caspian Sea was shared between the Soviet Union and Iran in accordance with the 1921 Treaty of Moscow (Glantz, 1999). However, when the communist system broke down in 1991, this changed the political landscape and three more countries were added to the list of Caspian littoral states: Azerbaijan, Turkmenistan, and Kazakhstan (Glantz, 1999).
Another study also notes that "the Caspian coastal zone of the Russian Federation belongs to areas with heavily disturbed ecosystems" (Environmental Problems of the Caspian Region, 1998). At the same time, "this region contains the most valuable specially protected natural land and water areas that are necessary to maintain species diversity and to preserve Caspian bio-resources, and can serve as nuclei of natural regeneration of the degraded ecosystems" (Environmental Problems of the Caspian Region, 1998).
Central to the various environmental problems in the area, and particularly in the sea itself, is pollution. An analysis of the situation from the perspective of Kazakhstan illustrates how waterways have become severely contaminated. The basic waterways of Kazakhstan — including the basins of the Irtysh, Ili, Nura, and Syr-Darya rivers — are being polluted by the mining, metallurgical, and chemical industries (Kazakhstan: Environment Issues and Policy). This is consistent with other findings: "The main pollutants are the non-ferrous metals industries (enrichment and melting of lead, copper, and zinc) and those not complying with modern ecological requirements" (Kazakhstan: Environment Issues and Policy).
There is increasing evidence that the soil and air in many of the countries surrounding the Caspian Sea have also become polluted, the result of long-term neglect. Related environmental concerns stem from oil, gas, and chemical industries, as well as from the use of toxic agricultural pesticides and the dumping of "untreated sewage and industrial wastes into the Caspian" (Glantz, 1999).
A serious concern is the effect that continued pollution may have on the wider ecosystem. A report from the Kazakhstan embassy warns that pollution levels can lead to more severe consequences for arable land and agriculture:
"Our country depends by more than 50% on water supplies coming from neighbouring countries and is vulnerable to global climate change. According to scientific forecasts, during the next 15–20 years present pastures and arable lands can fall into the category of desert and semi-desert lands and our water security can be reduced by a third." (Kazakhstan: Environment Issues and Policy)
More general surveys of the region have indicated very high levels of pesticides in the water, especially off the coasts of Azerbaijan and Iran (Experts Debate Ailing Caspian Sea). Other environmental concerns include the high demand for caviar, which has resulted in the reduction of sturgeon numbers, and oil leakage into the water (Experts Debate Ailing Caspian Sea).
"Post-Soviet political fragmentation blocking cooperation"
"Great Lakes model and the Caspian Sea Environment Program"
The problem of pollution and the reduction of arable land, among others, are set to increase in the future — especially when one considers the additional threat of global warming. The only viable solution is an integrated and internationally monitored plan of action, similar to the remedial plan implemented for the Great Lakes in North America.
