'Clearing thirsty alien vegetation a cheaper way to help fill up Cape dams'

"Alien vegetation still poses a significant threat to Cape Town's water supply. Clearing the water-guzzling invasive alien trees is the most cost-effective solution to help with the City of Cape Town’s water resilience plan. This is according to Louise Stafford, the Nature Conservancy's water fund project director for South Africa.  While city officials consider spending R8-billion on engineered solutions to boost Cape Town's water supply, Stafford says alien plant clearing will guarantee the most water return for the least cost. According to Stafford, a total of 50 billion litres (two months' water supply for Cape Town) could be harnessed if 54 000 hectares of identified alien vegetation is cleared around the Cape's dams."
