Downloaded from hlayiso.com Geography/P1 15 DBE/November 2023 NSC 2.5 Refer to the extract below on catchment and river management. ALIEN PLANTS ARE THE GREATEST THREAT TO CAPE TOWN'S WATER SECURITY Alien plants* are possibly the greatest threat to Cape Town's water security. The roots of plants absorb groundwater. The current water loss due to alien plants is more than 100 million litres which is nearly 20% of what Capetonians are currently using daily. To address water security, the city of Cape Town plans to extract water from aquifers** in addition to existing dams. However, the plan to extract groundwater is experiencing challenges due to alien trees absorbing groundwater in the mountain catchment areas. Extracting groundwater (by drilling boreholes into aquifers) to add to the existing water supply, without addressing the clearing of alien plans, will cause a bigger water supply problem in future. Catchment restoration (repair) is the solution to water security, and alien clearing programmes are key to this restoration. However, underfunding and inefficiencies are hampering the implementation of alien clearing programmes in the catchment areas. Restoring and maintaining our catchments in a healthy state are essential (important) for water security in Cape Town and the surrounding region. The threat of alien plants to water security will not go away and will only become a greater problem the longer it is not properly addressed. Glossary: *alien plants: plants from another country **aquifers: water-bearing rocks [Adapted from https://www.groundup.org.za/author/] 2.5.1 How much water is lost due to alien plants, according to the extract? (1 x 1) (1) 2.5.2 Give TWO plans in the extract that the Cape Town municipality intends to use to improve water security.
