A prolonged winter rainfall deficit is threatening wheat yields in parts of the Swartland, while rising input costs leave dryland farmers with limited financial protection.
Swartland grain producers in the Western Cape warn that 25% to 30% of crop potential could already have been lost on some farms. The estimate comes as farmers face a shortage of rainfall and a decline in planted hectares.
Grain SA says follow-up rain is urgently needed.
“But the situation exposes a much bigger problem: South African grain producers are increasingly being expected to carry climate and production risk that has become economically impossible to absorb alone,” the organisation said.
Grain SA CEO Dr Tobias Doyer said Swartland farmers were under severe pressure.
“This is not simply about one dry spell or one difficult season. Margins have been eroded over several years, production risks are increasing and producers have very little financial buffer left when the rain does not come.”
Grain SA said the Swartland entered the 2026 production season with encouraging rainfall. Regional data supplied by Overberg Agri showed approximately 176mm of rain during April and May, compared with a 10-year average of about 66mm.
“Farmers therefore planted, applied fertiliser and committed significant production expenditure despite economic pressure. Conditions then changed dramatically. From June to August, only about 43mm of rain was recorded, compared with a 10-year average of approximately 202mm—almost 79% below average,”added Grain SA.
For dryland producers, rainfall totals alone do not tell the full story.
“The timing and distribution of rainfall determine whether a crop can reach its potential. By the time conditions deteriorate, much of the cost of producing that crop has already been incurred.
“Seed cannot be unplanted. Fertiliser cannot be taken back. Diesel, labour, finance and crop-protection costs have already been committed,” said Grain SA.
Grain SA said that farm-level figures supplied by a Swartland producer show that, between 2016 and 2026, direct input costs increased by approximately 65%, while the estimated farm-gate wheat price increased by about 36%.
“These figures do not fully account for sharp increases in machinery replacement, maintenance, labour, finance and the cost of capital,” Grain SA said.
Producers have responded by improving efficiency. They have adopted conservation agriculture, improved soil health and water-use efficiency, invested in better genetics and pursued higher yields.
Grain SA said affordable and meaningful crop insurance should become a national agricultural priority.
“South Africa has agricultural insurance products, but meaningful multi-peril or yield-based cover remains unaffordable or inaccessible to many dryland producers operating on extremely tight margins.”
Francois Rossouw, CEO of the Southern African Agri Initiative (SAAI), said the current pressure was not mainly the result of ongoing heavy rainfall.
“The Western Cape did experience severe storms and flooding in May, which damaged infrastructure and complicated the start of the season. Since then, however, Swartland has suffered a serious rainfall deficit during the critical winter-growing months.
“That dry spell, coming after two already difficult seasons, is what is now threatening yields.”
Rossouw said a loss of 25% to 30% of crop potential on some farms was a realistic estimate at this stage of the season.
“The damage is uneven: some lands still look reasonable, especially where conservation agriculture has conserved moisture, but warmer slopes and later-planted fields are under visible moisture stress.
“If follow-up rain does not arrive in time, those losses will widen further before harvest.”
Rossouw said national wheat plantings were already low, input costs remained high and many Swartland grain farms had fewer livestock or other enterprises to absorb a poor crop.
“For family farmers, a 25% to 30% yield loss is not only a production setback. It is a cash-flow, debt and succession problem.”
“SAAI’s view is that the government and the value chain should treat this as an early warning, rather than wait until after harvest. Affordable crop insurance for dryland producers, practical disaster-support mechanisms and a policy environment that makes wheat production viable again are needed,” added Rossouw
Wandile Sihlobo, chief economist at the Agricultural Business Chamber of South Africa (Agbiz), said the wheat crop in the Western Cape was not in good condition.
“The wheat plantings in the Western Cape, the major producing province, are rainfed. This means that if weather conditions were broadly favourable, despite all the challenges weighing on plantings, the harvest would still be decent.
“But that is not what we have experienced. Over the past few months, the Western Cape has experienced drier-than-usual weather conditions. As a result, the wheat crop in various regions of the province is not in good condition,”said
The Western Cape Department of Agriculture was approached for comment and said they would respond accordingly.
