After 2002, the government of the IMF dupe Festus Mogae, president of the ambitious state of Botswana, directed his apparatus to drive and flush and bribe the approximately 50 thousand Bushmen from their traditional, majestic Kalahari desert home and habitat.  The aim was to concentrate the available water into the hands of development, including a DeBeers facility to service fresh diamond mines and the usual tourist attractions for the elephant population.  Cynical, modern, determined, devoted, glib characters in a Dickens novel unwritten of 21st Century Africa.  A severe drought struck Botawana and reduced the central Gaborone Dam reservoir to 27% of capacity.  The nation panicked and abused the handful of remaining Bushmen.  James G. Workman traveled into the Kalahari to meet with the traditional people and came under the spell of an aged grandmother, Qoroxloo Duxee, born 1924, and her family and clan members.  Qoroxloo confronted the threats and abuses of the central government.  The apparatchik in charge, Sidney Pilane, declared the Bushmen holdouts and those who returned to the desert to be "terrorists."  Workman makes a parallel case that drought is a likely scenario for North America and other parts of the globe in the event of severe climate change.  Life with minimal water supplies is a profound challenge.  Following the  Bushmen into the desert to seek and preserve food and water is thrilling and a journey into science fiction.  In one hundred degree dry heat, a human being needs one gallon of water every 20 miles.  The confrontation between Bushmen and the IMF boys is predictable and satisfying.  The story is tragic and foreboding.  It will make you thirsty.  Mention that the IMF and World Bank convinced Botswana, as with other African states, to centralize its water reservoirs, and this is a catastrophe in waiting, as only diversified water management can adapt to climate change.
