Sustainable water research is big news in South Africa especially for the wine industry.
The South African wine industry is the 9th largest wine producer in the world, with over 100,000 hectares of land dedicated to vineyards.
South Africa is committed to sustainable wine growing and recognises the problems of cultivating the majority of its wine in a biodiversity hotspot: the Cape Floral Kingdom.
So the introduction of the integrity and sustainability seal for wine, launched in 2010, certifies that the wine in question has been made in a manner that is respectful to nature, and guarantees sustainable wine production.
To make their wines sustainable, producers are taking responsibility by dedicating land for conservation, removing foreign plants and restoring wetlands and rivers. But there have been particular issues in many regions, for example in the Witwatersrand Basin there are reports of soil being highly acidic and contamination of water resources.
