Natural resource conflicts have become a pervasive feature of intergroup relations in the 21^st Century. Its frequency, intensity and violent nature often throw up complex humanitarian challenges, necessitating interventions in order to alleviate the suffering of the affected population. Since 2015, herdsmen attacks on the farming communities have become a commonplace issue in Nigeria. This development is characterised with the destruction of livelihoods, killing and displacement of people, with north eastern zone being on the front burner of the discourse. Thus, this study appraised the humanitarian activities of non-state actors over natural resource conflict in Adamawa State, Nigeria. Key informant interview (KII) and focus group discussion (FGD) were deployed to gather data from six local government areas of Adamawa State, namely: Numan, Demsa, Girei, Mubi north, Madagali and Maiha. Data collected were analysed qualitatively. It was revealed that the non-state actors that intervened in the various conflict zones were individuals within and outside the state as well as a foreigner. The interventions provided by the non-state actors were mainly food items and to some extent non-food items. Also, the study uncovered that the major obstacles inhabiting the efficiency of non-state actors were insufficiency of relief materials, the flow pattern of interventions and non-delivery of interventions at the right locations. Therefore, it is essential for corporate non-state actors to be motivated to participate early and effectively in the provision and distribution interventions to ameliorate and strengthen the conditions of people in the affected communities in the state.
