<p>Herder-Farmer Conflict (HFC) remains a major threat to national cohesion and sustainable development in Nigeria. This study, therefore, examines the roles of population density and road density in shaping both the occurrence (onset) and intensity (frequency) of HFCs within Nomadic Pastoral Corridors (NPCs) delineated by the Conflict Corridor Model across four hotspot geopolitical zones in Nigeria. Using count-based conflict data, the study applied Poisson, negative binomial, and two-part hurdle models to evaluate the spatial dynamics of HFCs across corridor systems. The hurdle negative binomial model emerged as the best-fitting specification, indicating broad structural homogeneity in the effects of population density and road density across the aggregated conflict landscape and suggesting the dominant influence of unobserved socio-political, cultural, and environmental factors. However, disaggregated analyses using the Logit and Hurdle Poisson models reveal substantial spatial heterogeneity across NPCs. Both population density and road density exhibit context-dependent mitigating and aggravating effects on HFC onset and intensity. While population density primarily reflects localized socio-spatial pressures, road density more strongly shapes mobility-driven interactions and corridor accessibility dynamics. The study, therefore, advocates spatially targeted and evidence-based interventions tailored to localized socio-politico-cultural, road infrastructural, and environmental realities rather than uniform national policy responses.</p>
