KNYSNA NEWS - According to the Southern Cape Landowners Initiative (SCLI), fast-growing populations and urbanisation are placing increasing pressure on sparse natural resources.
According to Cobus Meiring of the SCLI, the urban expansion is particularly visible around towns on the coastal plateau such as George, Knysna, and Mossel Bay, and also in the Klein Karoo.
"As a mere example, sprawling new developments and townships on the outskirts of Oudtshoorn and formerly small rural communities such as Dysselsdorp are not only a present-day and future concern from a socio-economic perspective, but also in terms of natural resources, especially freshwater resources.
"The impact of more housing developments on the survival of biodiversity and the irreversible destruction of natural habitat where new land has to be cleared, increase pressure on the region's natural resources."
He acknowledged that the Southern Cape is no stranger to drought, and several towns in the region have still not really recovered from the severe drought which has wreaked havoc in recent times.
"The Kamanassie Dam near Dysselsdorp, for instance, has been completely empty for years, and even with substantial rain falling in its catchment in recent times, the dire situation has not changed. In as much as it is important to plan for present and future water demand management and consider all available options, the removal of invasive alien trees and bush encroachment in rivers and catchments such as that of the Kamanassie Dam is vital if stream flow is to be improved significantly," says Meiring.
Along the Garden Route well over 75 landowners, in collaboration with SCLI, have already started clearing feeder streams and riverbeds on their land, and the results are there for all to see, not only in terms of more water being freed up, but also of unique biodiversity such as near-extinct fynbos species making a comeback.
"As part of its water stewardship programme, SCLI has designed and developed modular floating evaporation suppression covers, which may well serve a significant purpose in a future where literally every drop counts, and where evaporation accounts for vast amounts of water lost from essential water storage dams," Meiring said.
