BAKU, June 30 (Reuters) – A legal framework could be drawn up this year on regional cooperation to monitor and seek to adapt to falling water levels ​in the Caspian Sea, which is shrinking at ‌an accelerated pace, a senior Azerbaijani water official told Reuters.

• The level of the Caspian, the world’s largest inland body of water, has fallen by about a metre (yard) over the last five years, 1.5 metres ‌in ​the last decade and 2.5 metres ⁠over the last 30 ⁠years, said Aliagha Azizov, deputy head of the State Control Service for Water Use and Protection at Azerbaijan’s State Water Resources Agency.

• “The sea is now retreating by 20-30 centimetres ​a year, dozens of times faster than the pace at which global sea levels are rising. We cannot ⁠stop this process. We can only ⁠adapt to it,” Azizov said.

• The water levels ​of the Caspian Sea, which lies between Azerbaijan and Kazakhstan, ​with Russia to the north and Iran and Turkmenistan ‌to the south, have been falling since the mid-1990s, scientific studies have found.

• Azizov said the main causes were climate change, lower rainfall across the sea basin, higher evaporation caused ⁠by rising temperatures and reduced flows from rivers feeding the sea.

• Ports, shipping, fisheries, coastal tourism and offshore oil and gas ⁠infrastructure are also ‌more vulnerable as a result, he said.

• ⁠The five countries surrounding the sea are working ​to ‌strengthen cooperation to protect the surrounding environment, ​but there ⁠is no fully functioning regional monitoring system, Azizov said.

• The legal framework for regional cooperation on monitoring, data exchange, joint scientific research, forecasts and adaptation measures could be completed by the end of this year, he said.
