The aim of this study is to examine conflict and how it impinges on development. Conflict is an inevitable element of human existence since creation and has always affected human activities and endeavors in several ways. Understanding the dimensions of human conflict therefore provides blueprints on how to manage and resolve conflicts. This makes this study timely. In this research, some relevant related to conflict management approaches were examined. The research adopted a case study approach using the Jos Plateau conflict in the Plateau State of the Federal Republic of Nigeria. Data was collected and analyzed using a mixed research methods approach. The findings show several causes of this conflict among which are differences in religious beliefs among the people of the area, socio-economic causes, political tensions and land disputes. The consequences of the conflict identified are: it retards development in the area, creates fear and feelings of insecurity, destruction of property and loss of human lives. This study also examined how the conflict impinges on people-cantered development. In terms of how the conflict can be mitigated, respondents think education, creation of employment opportunities, the administration of justice and the practice of tolerance values is going to promote a spirit of coexistence and eventually result in a more peaceful and stable environment.
