A day before the march, dalit activists as well as the victims of atrocities from across India, including the Una incident victims, will gather in Ahmedabad to take part in a conclave where they would highlight their demands.
The dalit leader warned the ruling BJP that it would face "consequences" during this year's assembly election if the state government did not accept their demands.
According to Mevani, the march, named as 'Azadi Kooch,' would commence from Mehsana town and will end at a village in Banaskantha district of north Gujarat or at Rapar village of Kutch district after seven days.
He alleged that despite promises made to dalits by the Gujarat government as well as the Centre, nothing has changed on the ground even after one year of Una incident.

According to Mevani, the key agenda of this march is to mount pressure on the Gujarat government to allocate agricultural land to dalits, so that they can start a new life with dignity.
"Dalits want freedom from cleaning gutters as well as from the ancestral work of disposing animal carcasses. We want the government to start the allocation of 1.63 lakh acres of land to dalits and landless farmers as per the law. We will seek support of OBCs, farmers and other communities for our movement," said Mevani.
"If dalits, OBCs and other eligible communities will not be given this agricultural land, we will give a call to vote against the BJP in this year's polls," he added.
On July 11 last year, seven dalits of Mota Samadhiyala village of Una taluka in Gir-Somnath district were allegedly thrashed by cow vigilantes when they were skinning a dead cow.
Later, four of these dalit youths were taken to Una town, where they were tied up with a vehicle and allegedly thrashed by the gau-rakshaks.
