The royal couple, who wed in April, will visit a UNICEF centre in Copenhagen, Denmark on November 2, reports People.
During their visit, UNICEF will teach William and Kate about how to give emergency food and medical supplies to East Africa, as well as learn about the famine affecting the region.
The royal couple apparently hope that their visit will continue to draw global attention to the famine crisis.
Back in June, William and Kate's Royal Wedding Charitable Gift Fund raised more than £1 million ($1.62 million).
The money raised from the fund will help to benefit 26 different charities selected by William and Kate.
