- Description
- Rural South Africa is faced with immense challenges including poverty, unemployment, low agriculture productivity, food and nutritional insecurity and inequalities. Against this background, enhancing rural agricultural productivity using proven technologies such as genetically modified (GM) maize production is suggested as a pathway to economic development and poverty reduction. Literature suggests that GM technology can increase crop yields, drought tolerance, reduced weeding labour costs and chemical spray costs. However, GM maize varieties available on the market currently were created to fit large-scale, capital-intensive, industrialised, and economically oriented agricultural systems. As a result, their uptake has been significantly slow especially in rural areas where several stakeholders are now questioning the potential of GM technology. With that background, this study aimed to understand determinants of gm maize production among rural farming households and their perceptions using the case of Ngqushwa Local Municipality. Specifically, the study sought to analyse types of maize varieties grown by rural households, associated yields, area allocation, rural households’ perceptions of GM maize, and to estimate factors that influence GM maize awareness, participation and intensity of production among this subsector. Using a cross-sectional survey research design, a sample size of 400 households was randomly selected and interviewed using a semi-structured questionnaire. The types of maize varieties grown by rural households, associated yields, area allocation and rural households’ perceptions of GM maize were analysed using descriptive statistics. Factors that influence GM maize awareness, participation, and intensity of production were estimated using a triple hurdle model where the 1st and 2nd hurdle were estimated using Probit regression, and 3rd hurdle a Tobit regression. The study revealed that landrace maize varieties are currently the most popular maize varieties grown by the majority of rural farming households from the study area producing higher yields (0.6t/ha) as compared to other hybrids (GM – 0.5t/ha, conventional hybrids -0.3t/ha and improved OPVs – 0.1t/ha). Descriptive statistics results also indicated that farming households from the study area allocated more land to landrace maize varieties (42percent) compared to other maize varieties (GM maize (30percent), hybrids (21percent) and improved OPVs (7percent) further supporting the notion that landrace maize varieties dominate the rural farming subsector. Perception results revealed that the majority (57percent) of the households perceived GM maize as an expensive variety which, however, has a potential to produce relatively higher yields than other hybrids on the market and eliminates several production problems (manual weeding, pest spraying) making farm management easier. Findings further indicate that the majority (52percent) of the farming households from the study area did not have sufficient knowledge of GM maize. Econometrics results revealed that GM maize awareness is negatively influenced by age and gender and positively influenced by marital status, employment status and number of years in school. Conditional on awareness of GM maize varieties, both participation and intensity of participation in GM maize production are positively influenced by land size, gender, group membership, size of arable land and negatively influenced by employment status and income. Against this background, the study concludes that farming households from the study area produced more compared to the other varieties. Furthermore, the study concludes that households get higher yields from landrace maize varieties and allocate more of their land to landrace maize production. In addition, the study also concludes that most rural farmers perceive participation in GM maize as beneficial especially towards elimination of farm management problems, produces higher yields, and makes farm management easier. Lastly, the study concludes that GM maize awareness is negatively influenced by age and gender and positively influenced by marital status, employment status and number of years in school. Both participation and intensity of participation in GM maize production are positively influenced by land size, gender, group membership, arable land and negatively influenced by employment status and income. The study recommends that priority should be given to these socio-economic and institutional factors and this may be addressed by targeting GM maize awareness campaigns and platforms more suited to female-headed, older, lowly educated and unemployed rural farming households.
