The Lady Khama Charitable Trust was founded in 2002 in honour of Lady Ruth Khama, the wife of Botswana’s first President Sir Seretse Khama who until her passing in 2004 had played an active and passionate role in Botswana supporting and caring for those in need. The Trust partners with existing charitable organizations, to work on community development and in particular projects which support vulnerable women and children. The strength of the Lady Khama Trust is its  ability to identify and evaluate potential beneficiaries and projects, raise financing and to provide support for these organizations to meet their objectives and to operate with strong governance and integrity.
