(Clifford) Allan Redin Savory (born September 15, 1935) is a Zimbabwean biologist, farmer, soldier, exile, environmentalist and winner of the Banksia International Award 2003. and winner of the Buckminster Fuller Award 2010. He is the originator of the Holistic Management concept.

Savory was elected into the Rhodesian Parliament representing Matobo constituency in the 1970 election. After resigning from the Rhodesian Front in protest over its racist policies and handling of the war, Savory reformed the defunct Rhodesia Party formerly led by Sir Roy Welensky. Subsequently all moderate white parties united in opposition to Ian Smith in what was known as the National Unifying Force (NUF) led by Savory. When Savory made a public statement that if he had been born a black Rhodesian he would have been a guerilla fighter and urged white Rhodesians to understand why he would feel this, Ian Smith denounced him as a traitor. Because the NUF party would not stand by Savory he relinquished leadership to Tim Gibbs, son of Rhodesia’s last Governor. Savory continued to fight Ian Smith and his policies, in particular opposing the Internal Settlement under Bishop Abel Muzorewa. Finally faced with detention by the Smith government Savory escaped and went into self imposed exile to continue his scientific work as there was no more he felt a white Rhodesian could do to speed an end to the civil war.
