The Sahel Migration Crisis, Fulani Transhumance and the Dilemma of Nation – State Sovereignty in West Africa: A Legal and Policy Analysis

The Sahel migration crisis exemplifies the tension between ecological necessity, cultural identity, and legal sovereignty in West Africa. Driven by desertification, climate change, violent extremism, and resource competition, pastoralist mobility (particularly Fulani transhumance) clashes with modern nation-state frameworks. While ECOWAS protocols of 1979 and 1998 guarantee free movement and transhumance rights, national constitutions, statutory laws, and judicial precedents often prioritize sovereignty and border control. This paradox undermines regional integration and exacerbates farmer-herder conflicts. Historically, Fulani transhumance was sustained through customary arbitration and communal land tenure, but colonial and postcolonial legal regimes entrenched fixed borders and statutory land ownership, marginalizing pastoral mobility. The paper argues that reconciling sovereignty with mobility requires innovative law-making that integrates customary practices, human rights obligations, and regional frameworks. Ultimately, the Sahel crisis reveals the need for adaptive legal pluralism to balance security, sovereignty, and cultural resilience in pastoralist livelihoods.
