Prof Timothy Dube harnesses AI to revolutionise water management
At the nexus of hydrology and cutting-edge technology, Prof Timothy Dube leverages the power of artificial intelligence , machine learning and remote sensing to address one of humanity’s most pressing challenges — water scarcity.
Dube, Director of the Institute for Water Studies at the University of the Western Cape , is particularly interested in the often overlooked non-perennial rivers of semi-arid regions. In sub-Saharan Africa, two-thirds of rivers are non-perennial, meaning they do not flow all year round. These intermittent waterways have been historically neglected in research — a problem in an era where climate change threatens local and global water security.
The model, developed by Dube and his team, estimates water availability within N-PRs with approximately 85% accuracy — a significant development in regions where traditional monitoring methods fall short. “Our goal is to provide decision-makers with the most accurate and up-to-date information possible,” he says.
