Child hunger and deaths are rising in Zimbabwe due to the worst drought in two decades, with thousan.
The 'Cloud Atlas' actress is keen to start a new life in Europe with her fiancé Olivier Martinez but her former partner, Gabriel Aubry, has bitterly contested her plans to take their little girl, Nahla, now five, with them.
Halle is ready to delay her dream until the youngster is old enough to make her own decision on where she wants to live.
The Oscar winner said: "It probably won't be until my daughter is 18 and off to college. When Nahla turns 18, she'll be legally able to make her own decisions about where she wants to be and I think that then, when she's off on her own, we'll move there. It's where I want to end my days, that's for sure."
While Halle loves France, she won't be learning to speak French until she lives there as Olivier thinks it will be too much for her to take on at the moment.
In an interview with HELLO! magazine, she said: "I was told very lovingly by him not to work on it too hard now but to wait until we get to live there. Because for me, at my age and with all that I already have on my plate, trying to learn French is probably one of the hardest things I could possibly do.
"He thinks I'll have an easier time when we're living there and immersed in the culture - if we ever get to go that is."
