Brockington, D. (2002). Fortress Conservation: The Preservation of the Mkomazi Game Reserve, Tanzania. Oxford: James Currey; Bloomington: Indiana University Press.
Brockington’s study of Mkomazi Game Reserve, from which resident pastoralists were evicted in the late 1980s, examines the effects of eviction on the people removed and the conservation arguments offered for it. The book gave the term fortress conservation its documented reference case. The wiki takes the term for any protection of land or water that depends on removing the people who live there, including the clearing of residents from water towers.
