Smallholder farmers are the most in touch with the earth’s changing climate patterns, and they are the most vulnerable to increased temperatures and reduced rainfall. Dr Mary Funke Olabanji, from UP’s Department of Geography Geo-Informatics and Meteorology, wanted to know what exactly smallholder farmers know about climate change, and how difficult they find it to adapt.
She specifically looked at smallholder farmers in the Olifants catchment area in the north-eastern part of South Africa, where she surveyed their climate change knowledge and how they’re trying to adapt to it. She then compared this knowledge to meteorological data for the area over 30 years (1986 - 2015).
The study found that 98% of the farmers were aware of climate change and that their perception of climate change over 30 years aligns with actual meteorological data on decreased rainfall and increased temperatures. They found that the farmers were adjusting their planting and harvesting times to accommodate these changes.
Some of the farmers are trying to use seed and crop varieties that are resilient against heat and water shortages, but these are in short supply. Some are losing their interest in farming due to the difficulties that climate change brings.
Those who cannot adapt to climate change have more pressing matters to worry about, such as decreased yields and water shortages.
“Constraints to adaptation include a lack of access to credit services, government support usually reserved for bigger, commercial farmers such as subsidised water rates, and access to climate resilient crops,” says Dr Olabanji. Additionally, the farmers need access to loans in order to purchase irrigation and other equipment.
Dr Olabanji says the government could better support these smallholder farmers by providing them with flexible and affordable credit facilities. She says they could also benefit from more information on how to effectively adapt to climate change.
She worked with Dr Thando Ndarana (supervisor) and Dr Nerhene Davis (co-supervisor) on the paper.

In a first for precision agriculture, University of Pretoria (UP) researchers, in association with collaborators from the Council for Scientific and Industrial Research (CSIR), have produced maps of smallholder farms in Gauteng that highlight maize plants in green and weeds in red. The maps were shared with farmers to enable them to pinpoint and eradicate weeds with more precision.
Farmers not only save time and money by cutting down the cost and effort required to manage weeds, but also limit the environmental impact of using harmful weed-killing chemicals by using satellite data and imagery.
This classification map shows the different types of plants in a crop field in various areas in Gauteng. The legend shows red for weeds, green for maize and yellow for mixed growth areas.
