Climate change, rising temperatures, shifting weather patterns and increasing water demand pose significant threats to South Africa’s water security.

Discussions at Rand Water’s Talks Seminar on “What Threatens Water Security in South” highlighted the urgent need for collective action to address the challenges facing the country’s water sector.

Sharing critical facts about water availability, Dr Leslie Hoy, Manager of Environmental Management Services at Rand Water, said that the country’s water demand had surged by 600% since the 20th century. With climate change, managing this resource will become even harder.

By 2050, over 60% of the population will live in urban areas, further stressing water availability.

With rising temperatures and more frequent extreme rainfall events, the sustainable management of water is more urgent than ever, Hoy said, adding that our ecosystems and way of life is at risk.

Hoy emphasized the need for a holistic approach to address climate change in the water sector.

Securing South Africa’s water future requires changing how we use water This means adopting water reuse, improving water quality outputs from wastewater treatment plants, using groundwater, and implementing nature-based solutions alongside engineering to protect ecosystems.

Discussions at the seminar highlighted that South Africa must shift from reactive crisis management to proactive long-term water solutions.

Despite abundant water globally, only 3% is freshwater. The real challenge lies in the affordability of this resource going forward.

Water security impacts agriculture, housing, energy and industry. Therefore, addressing inefficiencies, such as water losses is crucial

Water wastage also leads to energy losses, highlighting the need for integrated solutions that address both.

In closing, addressing water security requires a unified, long-term approach across all sectors to ensure a sustainable future, was said at the seminar.
