Call to fight invasive plants to increase water supply

The Gamtoos Irrigation Board has called on private landowners to take a vested interest in the fight against alien invasive plant species, which are robbing the Eastern Cape’s supply dams of critical run-off from rains.

The department of environmental affairs has renewed its contract with the irrigation board to roll out the provincewide “Working For” natural resource management programmes – a move which will sustain 2,000 jobs throughout the Eastern Cape annually.

In addition to job creation, the contract also seeks to clear non-indigenous vegetation in a bid to maximise run-off to the province’s dams amid increasingly crippling drought conditions.

Under the new three-year contract, the board will manage four major project categories – working for water, wetlands, forestry and ecosystems. The renewal confirms the board’s status as a trusted regional service provider, responsible for managing various water-related projects on behalf of national government since 1999.

Its project footprint extends across the province – from Tsitsikamma in the west to Lusikisiki in the east and north to Matatiele.

Over the past five years, irrigation board contractors have cleared a total of 547,697 hectares of alien invasive plants. One hectare covers roughly the same area as an international rugby field.

“While funding for this is, in part, covered under the new contract, a lot more money is needed to have the desired impact,” said the board’s financial and HR manager, Rienette Colesky.

She said the National Environmental Management: Biodiversity Act required landowners to keep their land free from alien invasive plants.

“The government can subsidise only so much. We need clean catchments, but we can only do it with public-private partnerships,” said Colesky.

Chief executive officer Pierre Joubert said the organisation was delighted to be given the opportunity to continue the work it had been doing successfully for almost two decades.

“It is vitally important for us to be involved in poverty alleviation, while at the same time improving flow of water into the dams.”

The board enlists the services of more than 300 SMME contractors. This creates a positive economic impact for at least 3,000 additional beneficiaries and their households.
