Thirty-five young farmers from north Powys are flying to Africa to help children with HIV.
The members of Montgomeryshire Young Farmers' Club (YFC) will spend 12 days in the village of Plateau, western Kenya, working on two schemes.
The projects will see the young farmers building chicken pens, while they will also work on a new school sports field.
Eggs from the chickens will be used in a hospital as extra nourishment for the children who have HIV.
Montgomeryshire YFC said nutrition was an important part of the fight against HIV/AIDS.
Nicola Walker of the YFC said: "We will be doing the sports field for the local school and the chicken layer unit for the hospital.
"We've arranged the trip in partnership with the charity GapKenya, who have people working for them from Llandinam (near Newtown), and it is they who have identified the two projects as being most beneficial to the village.
"The initial figure we needed to raise for these projects was £1,750, but to date we have already sent them £5,500 and money is still coming in. We're hoping that the extra will fund things like repairs to wells and equipment for the school and hospital."
She added that 35 people, aged between 18 and 31, from 14 different YFC clubs in north Powys were taking part in the project.
They will also go on safari to Lake Nakuru National Park.
The young farmers fly to Kenya on Wednesday and return home on 31 October.
