Prime Minister Abdalla Hamdok said the forces would protect people during the farming season, BBC reported.
Unidentified gunmen killed more than 60 people in the region on Saturday, and another 20 the day before, the UN said.
Hundreds of thousands of people have died in fighting between government forces and rebels since 2003. Millions have been forced from their homes.
More than a decade later, people finally started returning home in time for this year's July-November planting season after a government-sponsored deal was reached two months ago.
But this has led a new conflict over land rights between the people who took over the land with those who have returned.
In the latest upsurge, several villages were burned, and markets and shops looted, said the UN Office for the Coordination of Humanitarian Affairs (OCHA).
"The escalation of violence in different parts of Darfur region is leading to increased displacement, compromising the agricultural season, causing loss of lives and livelihoods and driving growing humanitarian needs," it said in a statement.
No group has so far said it carried out the attacks.
Former president, Omar al-Bashir, who was overthrown last year, is wanted by the International Criminal Court (ICC) for alleged war crimes and genocide in the region.
Last week, the 76-year-old went on trial in Sudan's capital Khartoum in connection with the 1989 military coup that brought him to power.
He could face the death penalty if found guilty.
