Interior CS Kithure Kindiki now says the government has started fencing and planting riverine ecosystem trees on the reclaimed riparian land, along the Nairobi Rivers Corridors.
Speaking after he toured various sections of the ongoing rehabilitation, Kindiki said the government has hired people from the local Community-Based Organisations (CBOs) and youth groups to do the work.
The CS said the reclamation and regeneration of the riparian corridor ecosystem will prevent re-encroachment.
Kindiki said the process will also see the Nairobi Rivers unclogged, drained, and rehabilitated.
He said recreation facilities will be established on both sides of the riparian reserves for access and use by members of the public for free.
The Interior CS noted that reclaiming the Nairobi Rivers Ecosystem will boost security for communities living around it.
He said it would also eliminate the menace of illicit alcohol brewing, narcotic drug peddling, and flush out dangerous criminals using the encroached riparian corridors as hideouts.
This comes a few weeks after the government ordered voluntary vacations and evacuation of people who lived and worked along the Nairobi River.
It had also ordered the removal of structures that were built within 30 metres of the riverlines.
Kindiki directed the Nairobi Regional and County Security Teams to work with the Nairobi City County Government and the National Disaster Operation Centre (NDOC) to ensure immediate vacation of people living along the rivers.
The directives followed flooding across the country, which was a result of heavy rains the country was experiencing.
The orders also applied to Kenyans who lived near waterbodies across the country, including dams that were almost overflowing.
Almost 300 people died as a result of the floods.
