I am trying to find the name of a movie I loved as a kid in the late 70's or sometime in the 80's.?

It was about a family that had moved to Africa and there was a drought or other disaster that made food scarce. The lions began attacking people because food was so scarce. A family and their workers ended up being hunted and were trapped inside their home. I loved it when I was a kid and would love to see if it is available now, but I don't remember the name.
