This research has been dedicated to the study of possibilities to develop a buffer zone around the National Parc of Kahuzi – Bièga (Pnkb) at Bugorhe and Irambi – Katana, South – Kivu, DR Congo. The study has examined the possibilities to allocate bordering fallow and under-exploited land into the buffer zone, for farming and tree planting by the little neighboring farmers. It has shown that seven lots bordering the park with 920Ha total area provide rentable farms to 473 neighboring farms. Nearly 494Ha of these lots are either fallow or under-exploited, which is about 53,7%, and are likely to be transformed into a buffer zone upon negotiating with land owners for buyout.
