The Constitutionality of State Anti-Open Grazing Laws: Implications for Herder-Farmer Conflicts in Benue State

Herder-farmer conflicts have emerged as one of Nigeria's most complex and deadly sources of civil unrest, with North Central states, particularly Benue State, recording high incidences of violent clashes, displacement, and loss of life. In 2017, Benue State enacted the Open Grazing Prohibition and Ranches Establishment Law, triggering significant controversy around its constitutionality and practical implications. This study examines the legal validity of Benue State's anti-open grazing legislation against the backdrop of the constitutional framework governing land use, freedom of movement, and inter-governmental relations in Nigeria. A doctrinal legal methodology is employed, analysing the constitutional text, legislative history, judicial precedents, and scholarly commentary published between 2018 and 2024. The study also draws on field data collected through structured interviews with farmers, herder community representatives, and legal officers in Makurdi and Guma local government areas. The analysis reveals ongoing tensions between state legislative competence and federal exclusivity over agricultural policy and interstate commerce. The findings suggest that while the state's security justification is compelling, some provisions may conflict with constitutional limitations on state legislative authority. Recommendations include federal legislation to establish a comprehensive national ranching framework and enhanced intergovernmental dialogue mechanisms. This study contributes to the constitutional law discourse on federalism and resource conflict in Nigeria.
