Delta Blues (In a Land of Cotton) is a 2001 documentary film.
[1] The movie deals with the environmental problems emanating from the drying up of the Aral Sea, and the impact this has on political relationships in the Central Asian region (especially Uzbekistan, Kazakhstan, Kyrgyzstan, and Turkmenistan).
In particular, it focuses on the document Water-related vision for the Aral Sea basin for the year 2025[2] by UNESCO, as presented in 2000 at the 2nd World Water Forum in The Hague.
This document has been criticized for setting unrealistic goals, and also, by focusing on the entire basin (south-west Kazakhstan, Uzbekistan, Turkmenistan), for implicitly giving up on the Aral Sea and the people living downstream in Karakalpakstan.
