This article aims to guide United Nations (UN) agencies, non-governmental organizations and government agencies engaged in the maintenance of international peace and security to reflect on the relevance of addressing natural resources and climate change in peacekeeping mandates, based on an analysis of the conflict in Darfur and the establishment of the United Nations - African Union Hybrid Operation in Darfur (UNAMID). To this end, it will present considerations about the evolution of the concept of peace and its influence in changing the profile of peace operations mandates, as well as the growing debate and publications at the UN level on the impacts of natural resources and climate change over security. Despite greater engagement, these issues are not included in the mandates per se or are undervalued, being marginally mentioned. The conflict in Darfur has its root causes in the limited availability of land and water scarcity due to the local climate, and these factors are exacerbated by climate change and population growth. Nevertheless, the local conflict is often characterized as an ethnic conflict, therefore the real sources of disputes have never been properly addressed by UNAMID in order to maintain, build and sustain peace. Mandates, resolutions and reports from the Security Council, the General Assembly and the United Nations Secretary-General will be reviewed to argue about the importance of considering natural resources and climate change when formulating a mandate with the aim of achieving peacebuilding and sustaining peace.
