NGOs working in the sector

TFRD NGO (Tropical Forest and Rural Development) intervenes in the northern periphery of the Dja Reserve on 30 000 hectares with 24 villages. They reinforce more than 160 farmers including 50 women, to develop certified Rainforest Alliance cacao sector, and to valorise non-timber forest products.

AAFEBEN NGO (Appui à l’autopromotion de la femme de la Boumba et de Ngoko) intervenes in the Easter periphery of the Dja Reserve on 10 community forests of 50 000 hectares. It supports 10 women groups totalling 350 women, mostly from the Baka (Pygmy people) and Bantu ethnic groups; and work in harvest and commercialisation of non-timber forest products.


Impact on biodiversity and local communities

Njansang has a high economic value for the forest communities, yet it remains undervalued. Valorisation of non-timber forest product (NTFPs) facilitates incomes’ increases for the population who therefore see also an economic interest to protect and manage lastingly the tropical forest.

In addition, communities are supported to implant tree nurseries close to housing areas and fields. This eases the harvesting, the renewal of NWFP and limits the impact of harvesting on natural recovery.
