The office of the Environmental Commissioner is introducing additional conditions, to be met in environmental clearance certificates, issued in respect to sand mining, timber harvesting and extraction of natural resources from communal areas. Environment and Tourism Minister Pohamba Shifeta announced this at a press briefing in Windhoek. The conditions, Shifeta says, are borne out of concern that the utilisation of many natural resources, including sand and timber, is not being done to the benefit of present and future generations.
