Global warming, increased human use, and declines in the flow of water from rivers that feed the Caspian Sea are threatening its viability. Food production from the sea is declining, and the Caspian’s ports and sea lanes are silting up, limiting north–south and east–west trade and advantaging countries that use small vessels over Russia, which relies on large ships. The Caspian littoral countries, as well as others further afield such as the People’s Republic of China (PRC), are worried, but they are unlikely to unite to find a solution. Instead, the countries surrounding the sea are splitting into blocs, preparing for the possibility of needing to use force to defend their interests in the Caspian.
