The goal of our study is to determine the impact of the NGO Wild Life on the improvement of the socio-economic conditions of the population of KOKOLOPORI. To do this, we conducted surveys and interviews with the wildlife workers and farmers of KOKOLOPORI.The following parameters were studied:- The wild life contributes in the schooling of the children of its workers by granting jobs to the persons in charge of the children.- Wildlife helps the population of KOKOLOPORI in particular and the Djolu territory in general to improve and increase their agricultural production.- In relation to the generative activities, the result shows that the wild life works in all the extent of KOKOLOPORI and the center of the territory of Djolu;- In relation to the negative impact, the result shows us that there is a low awareness of the conservation and development concept and there is also a quasi bias within the NGO Wild Life.
