Societal Impacts of Agricultural Technology (20 marks)
Economic impacts of agricultural technology
Agricultural technology has significant potential to transform the economic
performance of South Africa’s agricultural sector by increasing productivity, reducing
production costs and improving the efficiency with which scarce resources are utilised.
Technologies such as precision agriculture, satellite-based monitoring, automated
irrigation, agricultural drones, sensors and artificial intelligence enable farmers to make
decisions based on real-time information rather than relying exclusively on traditional
observation and experience. This can improve yields, reduce unnecessary expenditure
on inputs and strengthen the competitiveness of South African agriculture. The
economic value of these technologies is particularly important in a context where
farmers face rising input prices, climate variability, water constraints and pressure to
produce more food from limited productive land (Soeker, Lusinga and Chigona, 2021).
A significant economic benefit is the potential reduction in input costs. Precision
technologies allow farmers to apply fertilisers, pesticides and water more selectively,
thereby reducing wastage while maintaining or improving crop performance.
Agricultural drones are particularly useful because they can identify crop stress and
apply chemicals to specific areas rather than treating an entire field uniformly. This can
reduce labour, fuel, chemical and water costs while increasing operational efficiency.
,However, the economic benefits are not automatically available to all farmers.
Sophisticated machinery, sensors, drones, software and reliable connectivity require
substantial initial investment, technical expertise and maintenance. Consequently,
wealthier commercial farmers may benefit disproportionately, while smallholder farmers
may struggle to adopt expensive technologies. The economic impact of agricultural
technology therefore depends not only on technological innovation but also on
affordability, access to finance, training and appropriate support services.
A real-world South African example is the use of precision drone spraying among
smallholder sugarcane farmers in KwaZulu-Natal. A GreenCape case study of an
approximately 80-hectare sugarcane cooperative found that precision drone spraying
could reduce costs by up to 25%, while also improving yield and crop quality under
particular field conditions (GreenCape, 2025). This illustrates how agricultural technology
can have a direct economic effect on small-scale producers by reducing production
costs and improving the commercial viability of farming. Similarly, trials involving South
African smallholder sugarcane farmers found increases in estimated recoverable crystal
yields following drone-based ripening interventions, demonstrating the potential of
agricultural technology to improve both productivity and farmer income (DJI Agriculture,
2024).
Nevertheless, a critical evaluation must recognise that technology can also create
economic disadvantages. Mechanisation and automation may reduce demand for
certain forms of low-skilled agricultural labour, particularly where machines replace
repetitive manual activities. At the same time, agricultural technology can create new
employment opportunities in areas such as drone operation, data analysis, equipment
maintenance, agricultural software and technical support. The economic consequence is
therefore not simply job creation or job destruction; rather, technological change can
, restructure the agricultural labour market and increase demand for workers with digital
and technical competencies.
Social impacts of agricultural technology
Agricultural technology can generate important social benefits by improving food
security, supporting rural livelihoods and expanding farmers’ access to agricultural
information. Mobile applications, digital extension services, weather platforms and
online agricultural marketplaces can connect farmers with information about weather
conditions, market prices, pests, diseases and appropriate farming practices. This
reduces the geographical barriers that traditionally limited rural farmers’ access to
extension officers and specialist knowledge. ICT-based agricultural services can
therefore contribute to greater knowledge sharing and potentially strengthen the
decision-making capacity of farmers (Ayim et al., 2020).
Technology can also contribute to the empowerment of smallholder farmers by
enabling them to participate more effectively in agricultural value chains. Digital
platforms can provide information about commodity prices and connect producers with
buyers, thereby potentially reducing information asymmetries between rural producers
and larger market participants. Agricultural technologies can also support more inclusive
farming when they are designed around the needs and circumstances of women, young
people and historically marginalised rural communities.
However, the social effects of agricultural technology can also reinforce existing
inequalities. Farmers who have access to smartphones, computers, broadband,
electricity, technical training and financial resources are more capable of benefiting from
digital agriculture than farmers who lack these resources. The digitalisation of
agriculture can therefore produce a new form of inequality in which technological
competence becomes an additional determinant of agricultural opportunity. This is
