South Africa Urged to Embrace Water-Wise Farming as Climate Pressures Mount

According to the Water Research Commission (WRC), South Africa's long-term food security and the livelihoods of millions of people depend on how effectively the agricultural sector manages its water resources in the years ahead. Agriculture currently accounts for between 60% and 62% of the country's water use, making efficient water management essential as climate change, ageing infrastructure and recurring droughts continue to place increasing pressure on already limited supplies.

In an opinion piece, WRC Chief Executive Officer Dr Jennifer Balatedi Molwantwa said the country has reached a critical point where water conservation can no longer be viewed as an environmental issue alone, but as a key pillar of economic growth, food production and rural development.

She warned that if current trends continue, South Africa's water demand could exceed available supply by as much as 17% by 2030, creating significant challenges for farmers, agribusinesses and communities that depend on agriculture for income and food.

Despite these challenges, the WRC believes practical solutions already exist.

Across the country, farmers are increasingly adopting drought-resistant indigenous crops such as sorghum, millet, cowpeas and groundnuts, while regenerative farming practices including mulching, cover cropping, composting and reduced tillage are helping soils retain more moisture and improve resilience during dry periods.

Technology is also playing a growing role. Smart irrigation systems, soil moisture sensors and satellite monitoring are enabling farmers to use water more efficiently, reduce wastage and make informed decisions about irrigation and crop management.

These efforts form part of the WRC's A WaterWise Nation campaign, which encourages every South African, from households and businesses to municipalities and farmers, to adopt more responsible water-use practices.
