In 1985 De Beers mining company drilled a borehole for prospecting purposes and some of the water was supplied to settlements in CKGR. The Government later evicted and resettled the Basarwa outside of the CKGR because they felt that human settlements were incompatible with the conservation of wildlife in the preserve. In an attempt to dissuade the Basarwa from returning, the borehole was also dismantled as it was the only source of water within 40km. In 2006, in the Sesana case, the Court found that this eviction was unconstitutional and allowed the Basarwa to return to the CKGR.
