25. Historically, the level of the Caspian Sea has fluctuated greatly. The lowest level for the last five hundred years has reached in 1977 (-29m below sea level); therefore, it is a fair assumption that the level could continue to rise from the current level (-26m) until it reaches at least the 1900 level (-25m), presenting the littoral states with many urgent investment needs. In less than two decades, water levels have risen two and half meters, inundating residential areas, transport, telecommunication and energy infrastructure, chemical and petrochemical industries, croplands and hatcheries. Thousands of residents have been evacuated from flooded homes, and up to 100,000 people in coastal cities and towns in Azerbaijan alone have been affected by the spread of toxic wasters, contamination of water supplies, loss of infrastructure, and inundation of workplaces and settlements.

26. The problems associated with the changing sea level can be seen as falling into two main categories:

I) those that are exacerbated by the rising water, such as the spread of toxic contaminants into ground and surface waters, the collapse of vital fisheries due to the loss of natural and artificial hatcheries, and increased pressure on fragile lands because of displaced activities and communities; and

II) those that are caused by changing water levels, such as residential flooding, saltwater intrusion into freshwater aquifers and the submersion of productive infrastructure (coastal factories, farms, roads, railways, etc.).

27. In view of the history of fluctuating water levels in the Caspian, the current problems posed by the high water level are considered transitory. The best solutions are therefore those that are temporary and reversible. For this reason, increasing the rate of evaporation is thought to be a better solution, since it is reversible, and has in fact already been done through the re– opening of the channel leading into the Kara Bogaz Gol.

28. Investments in homes and factories or farms are painful to lose, and loss of infrastructure such as roads and railways has strategic a importance because economic growth depends on it. The protection of railways has the highest priority because railway lines are usually built on dike, and can therefore be protected more cheaply. Telephone lines, electricity transmission lines and pipelines are also of strategic importance and need to be protected, although the cost of moving telephone and power lines is relatively small compared to the cost of moving pipelines.
