The 75-year-old former military ruler will also tour other hotspots from Monday onwards, including areas hit by bloody clashes between semi-nomadic herders.
The former general, who came to power in 2015 vowing to crush Boko Haram’s jihadist insurgency, has not stated whether he will seek re-election in February 2019, but a surge in violence has cast a shadow over his term.
He has repeatedly declared the insurgents’ defeat for more than a year. That was undermined by mass the abduction in the town of Dapchi in Yobe State on February 19 and an attack on Thursday that killed at least 11 people, including three aid workers in another part of the northeast.
His tour will begin in the “Middle Belt” state of Taraba, where herdsmen have farmers have fought over dwindling arable land, his office said.
He will also visit central Nigeria’s Benue State and Zamfara State in the northwest, which have both been hit by fighting over grazing in recent weeks.
Other states he will visit are Rivers State in the south, as well as Yobe State in the northeast.
“The president has decided to undertake an on the spot assessment of the various occurrences and to meet and console the communities affected,” the presidency said.
The presidency did not say whether Buhari would visit Dapchi on his trip to Yobe.
Buhari’s predecessor, Goodluck Jonathan, was criticized for failing to quickly visit Chibok, the scene of another mass abduction of schoolgirls in 2014. That was seized upon by his detractors in the 2015 election campaign.
The opposition People’s Democratic Party had already called on Buhari to visit Dapchi in the days following the abduction.
Boko Haram, which has killed tens of thousands of people since 2009 in its bid to create an Islamic state, lost most of its territory in the face of an offensive by Nigeria’s army backed by troops from neighboring countries in early 2015.
But factions of the group have continued to carry out suicide bomb attacks and gun raids in the northeast, Cameroon, Niger, and Chad since then.
The violence linked to grazing rights has killed more than 100 people since the start of the year.
