Lower winter rainfall to impact agriculture, water storage

As the SA Weather Service (SAWS) forecasts lower-than-average winter rainfall and higher-than-average temperatures for much of the country this winter, we take a look at the impacts this will have on certain sectors.

With South Africa a water-scarce country, residents will be urged to use this resource sparingly as relatively high winter temperatures will likely increase evaporation, with lower rainfall decreasing storage sources.

“Furthermore, minimum and maximum temperatures are expected to be mostly above normal across the country during the forecast period, and this will likely increase demand for cooling,” said SAWS in a statement.

“Relevant decision-makers are encouraged to take note of these possible outcomes and communicate with affected businesses and communities accordingly.”

Meanwhile, sun protection measures should be taken as increased exposure to high solar ultraviolet (UV) radiation could lead to UV and heat-related illnesses.

“Additionally, below-normal rainfall may cause health problems related to drier conditions. People are advised to take precautions and follow the guidance and recommendations of local authorities,” continues the statement.

With expected lower-than-normal rainfall over the southwestern part of South Africa, which usually receives significant winter rainfall, crop and livestock production could be impacted.

“The relevant decision-makers are encouraged to advise farmers in these regions to practice soil and water conservation, proper water harvesting and storage, and other appropriate farming practices,” concluded SAWS.
