The Biosphere Reserve of Yangambi (BRY) landscape is facing the challenge of conserving biodiversity while supporting the food security of local communities. Farmers, in search of fertile soil, travel long distances to establish their fields, sometimes in the core area of the reserve. Faced with this reality, agroforestry is an alternative that could contribute to improving local livelihoods while protecting forests and biodiversity in this protected area (PA). This study was conducted in order to identify factors which motivate and/or inhibit farmers for adopting agroforestry practices.To this end, household surveys were conducted in three villages bordering the BRY, namely Bengamisa, Lilanda and Yaselia villages. The results revealed that only age of farmers influence significantly agroforestry adoption and 56.2% of the respondents deliberately leave naturally occurring agroforestry species in their farmlands. In order to benefit from the collection of edible caterpillars and fruits, improvement of soil fertility, extraction of medicinal products, production of charcoal and exploitation of timber. However, 43.8% of respondents who were not in favor of agroforestry feared accidents due to windfall, as well as for the collapse of agricultural production.The ethnobotanical analysis revealed that Petersianthus macrocarpus sp. and Erythrophleum suaveolens sp. had the highest use value due to their multi-functionality in the BRY landscape.Thus, the extension work to promote these species could increase the rate of agroforestry adoption and contribute to sedentarization of farmers which in turn reduce the rate of deforestation and promote biodiversity conservation in BRY landscape.

This research aims to identify socio-economic and sanitarian impacts of the Kamuina Nsapu insurrection on the livelihood of rural populations in the territory of Miabi. It also seeks to understand the resilience mechanisms developed by the local community faced this psychosocial shock. Therefore, the household survey and structured interview were used for collecting data through the villages of Katende, Miketa and Tshilundu. In addition, the analysis method was explored for data processing by using R 3.5 software. After investigation, it was found that the Kamuina Nsapu phenomenon remains the major shock recorded by the respondents. This humanitarian shock had driven to socio-economic impacts: decreasing of livelihoods for local community which is linked with the increasing of insecurity and vulnerability in this rural area, on one hand. On the other hand, the sanitarian impact is namely the increase of severe malnutrition at around of 36.6%. Faced this mechanism, the local community are resorting more to migration as the main resilience mechanism to ensure their survival. Therefore, it is necessary to call on all stakeholders in this territory for helping local community to overcome this humanitarian tragedy.
