Climate change (CC) significantly impacts many regions in Africa, with the Sahel experiencing these impacts in diverse and interconnected ways. These impacts are direct natural hazards, such as floods and droughts, or indirect economic disruptions and displacements of already vulnerable populations. Benue, Nigeria, which relies on agriculture and fishing, has consistently experienced severe flooding due to heavy rainfall, the presence of the Rivers Benue and Niger River and the Lagdo reservoir in Northern Cameroon. Additionally, it has witnessed recurrent herder–farmer clashes, which are exacerbated by CC. Together, these impacts lead to the displacement of families, which end in internally displaced persons (IDP) camps. The inadequate facilities and support within the IDP camps predispose IDPs to a range of mental health issues, including post-traumatic stress disorder, depression, and suicide ideation. Research has focused on individual psychopathology, ignoring other impacts such as the dispersion of communities, the separation of families, and the disruption of traditional support systems. Despite the focus on individual rehabilitation in IDP camps, there is a lack of a community psychology (CP) perspective and approach that would address the broader collective needs of displaced groups. This opinion paper proposes a community-centred approach to rehabilitation, emphasising the role of CP in addressing the challenges faced by Benue IDPs through advocacy, designing social support systems, empowerment and resilience building. Community psychologists are urged to call for comprehensive mental health policies that include IDPs and collaborate with local and international bodies to design effective, tailored interventions for displaced communities.
