Abstract

Purpose: The aim of the study was to investigate the use of biotechnology in improving crop yields and sustainability in south Africa.

Methodology: The study adopted a desktop methodology. Desk research refers to secondary data or that which can be collected without fieldwork. Desk research is basically involved in collecting data from existing resources hence it is often considered a low cost technique as compared to field research, as the main cost is involved in executive's time, telephone charges and directories. Thus, the study relied on already published studies, reports and statistics. This secondary data was easily accessed through the online journals and library

Findings: The use of biotechnology in South Africa to improve crop yields and sustainability has yielded significant positive outcomes. Biotech crops, including drought-tolerant varieties and genetically modified maize, have been widely adopted by smallholder farmers, particularly in drought-prone areas. These crops have contributed to enhanced food security and increased resilience in the face of climate variability. Furthermore, studies have demonstrated that the adoption of biotech crops is associated with higher yields and reduced production costs, making farming more profitable. Overall, biotechnology plays a pivotal role in South Africa's agriculture, fostering both increased productivity and sustainability.

Unique Contribution to Theory, Practice and Policy: Theory of Green Revolution, Theory of Technological Determinism, Theory of Innovation Diffusion may be used to anchor future studies on use of biotechnology in improving crop yields and sustainability in south Africa. Findings can prioritize the development of drought-resistant crop varieties using biotechnology. Public-private partnerships can accelerate technology adoption and promote sustainable agriculture practices.
