Boko Haram is now restricted to three locations, Senate Committee on the Army Chairman, Senator Mohammed Ali Ndume, said on Tuesday.
He said more can be achieved with increased budgetary allocation to security agencies.
Ndume spoke at a one-day Northeast Security Summit convened by the Inspector-General of Police Mohammed Adamu.
He said: “We know that the key remaining location of the remaining insurgents is three: the Lake Chad fringes, the Mandara Mountains and the Sambisa Forest.
“With the current technology, the theatre commander said they can finish this war within three months.”
Ndume, who represented Senate President Ahmed Lawan, said insurgents cannot be defeated with conventional military tactics, meagre budgetary allocations and inadequate personnel.
He said: “The Army is doing well, but it’s not enough because we have not seen the end of it. Let me say that we cannot fight a war on this vast land that we have with only 150, 000 soldiers.
“Right now, the population of the Nigerian Army is 150,000 plus the 4000 recently released, which makes it 160,000 personnel.
“We cannot fight this war with less than 400, 000 Police. We cannot also police with what is budgeted for this year. The constitution says the security, welfare and lives of the people are paramount.
“How can you, therefore, have a meagre budgetary allocation for the police and a meagre N100 billion for the military?”
Adamu noted that the Police cannot succeed without adopting a people-oriented approach.
He said community policing initiatives and strategies will bring trust to the people and enhance internal security.
“Public trust, consent and partnership are the foundation upon which policing rests. Any policing architecture that alienates the people cannot achieve the mandate of crime control, regardless of how well equipped, motivated or trained a police agency could be.
“Police should continually engage citizens towards seeking their support and inputs to address security challenges, as they face various communities in 774 councils,” the IGP said.
He urged traditional institutions to utilise the existing system of traditional administration in crime management.
He said the people should “identify, dissect, prioritise” and report security threats.
Adamu said terrorism, banditry, kidnapping, cattle rustling and armed robbery “are fueled by violent extremism, high rate of firearms proliferation, border security challenges and security situation across Africa”.
He praised the Civilian Joint Task Force, saying they complement security agencies’ efforts.
Borno State Governor Babagana Umara Zulum charged the soldiers to be proactive in the fight by taking the war to the insurgents, instead of being on the defensive.
He said: “The issue of insurgency can be reduced to the barest minimum, if the fight is taken to the insurgents.”
Yobe State Governor Mai Mala Buni said that Boko Haram is the major serious security challenge faced by the nation in the last 10 years.
According to him, no nation can make socio-economic progress with persistent security challenges.
He pledged his support for the Army and the Police.
