Herder–farmer conflicts in Nigeria usually involve disputes over land and/or cattle between herders (in particular the Fulani or Hausa) and farmers (for example the Tiv or Tarok).
The most impacted states are those of the Nigerian Middle Belt like Benue, Taraba and Plateau.
Since the Fourth Nigerian Republic’s founding in 1999, farmer-herder violence has killed thousands of people and displaced tens of thousands more. It followed a trend in the increase of farmer-herder conflicts throughout much of the western Sahel, due to an expansion of agriculturist population and cultivated land at the expense of pasturelands; deteriorating environmental conditions, desertification and soil degradation; breakdown in traditional conflict resolution mechanisms of land and water disputes; and proliferation of small arms and crime in rural areas. Insecurity and violence have led many populations to create self-defence forces and ethnic militias, which have engaged in further violence. The majority of farmer-herder clashes have occurred between Muslim Fulani herdsmen and Christian peasants, exacerbating ethnoreligious hostilities.
According to the Global Terrorism Index, Fulani militants were the fourth deadliest terrorist group in 2014, using machine guns and attacks on villages to assault and intimidate farmers. After killing around 80 people in total from 2010 to 2013, they killed 1,229 in 2014. Most deaths occurred in the Nigerian Middle Belt, in particular in the states of Benue, Kaduna, Nasarawa, Plateau and Taraba, which recorded 847 deaths. The state of Zamfara, in the northern belt, recorded 229 deaths. In addition to terrorist attacks, Fulani militants were also involved in non-state armed conflicts with groups from Eggon, Jukun and Tiv farming communities. These conflicts resulted in 712 deaths.
