The Lake Basin Development Authority plans to build a dam inside the South Nandi forest that will lead to the clearing of 1,185 ha of closed canopy rainforest, including 10 million indigenous trees. The dam will significantly drain the Yala Swamp, a wetland of international importance by diverting 9% of waters of the Yalas river to the adjacent Nyando river. The governments aim is supposedly to divert water to the Nyanza sugar belt. But the project will alter local microclimate, adversely affect farming, and lead to biodiversity loss and habitat degradation. The proposed dam threatens wildlife, some of which are of global conservation concern. Kenya Forests Working group (KFWG, a consortium of institutions and environmental NGO) has taken the lead role in campaigning against the project; it has also vowed to object it.
