The Abuja Metropolitan Management Council has given the Abuja Environmental Protection Board a 48-hour ultimatum to clean up Abuja.
The experts, who spoke to journalists in separate interviews, condemned the indiscriminate dumping of wastes in drains, gutters and streets.
The authorities said most of those living in the shanties were without addresses and identification and this could produce challenges regarding insecurity.
“AEPB has been given marching order by the FCT Minister, Nyesom Wike, to clear all shanties, illegal markets and squatter camps in the FCT,” he said.
The executive secretary further urged farmers to imbibe climate-smart agriculture, which is irrigation farming.
“Grazing of animals along the airport road symbolises illegal acts,” Mr Braimah said.
On Tuesday, a mass trial of waste bill defaulters was conducted.
