An analysis of public perception towards consuming genetically modified crops and the acceptance of modern agricultural biotechnology: a South African case study

Abstract

South Africa is one of the biggest producers of genetically modified crops in the world. However, recent studies in South Africa show a low public willingness to consume genetically modified crops and accept modern agricultural biotechnology. The study analysed public perception towards consuming genetically modified crops and the acceptance of modern agricultural biotechnology in South Africa. 220 participants (N = 220) were sampled from the city of Kempton Park and the Chi-square formula was used to determine how well the sample represented the population under study. Data was collected using a 7-point Likert scale questionnaire designed following the guidelines for developing a theory of planned behaviour questionnaire in Ajzen (1991, 2001). Data analyses were carried out using the Statistical Package for Social Sciences (SPSS). The Cronbach’s alpha and Exploratory Factor Analysis were both used to determine the internal consistency and validity of the questionnaire. Correlations, independent sample t-tests, ANOVA, linear regression, and path analysis were also conducted. Findings of the study confirmed that there is low public willingness to consume genetically modified crops and to accept modern agricultural biotechnology in South Africa.
