- Description: Low maize yields in the midst of abundant arable land, favourable climatic conditions, input and financial support programs, plagues smallholder maize farming in Eastern Cape Province. These scenarios have led the province to be a net importer of maize. In essence, low production may signify a mis-match between maize varieties being promoted amongst smallholder farmers and their farming system. Thus, the main objective of the study was to investigate the productivity and profitability of different maize varieties and cropping system under smallholder agriculture in selected villages of the Eastern Cape Province of South Africa as well as, the implications posed on the household food security. The study sought to assess: (i) the productivity of different maize varieties and cropping systems, (ii) the effect of GM maize adoption on food security among smallholder farmers, (iii) the profitability of GM, conventional hybrids and OPV maize varieties produced by farmers under different agro-ecological conditions and (iv) the impact of different maize varieties and cropping systems on food security in the smallholder agriculture. A cross sectional quantitative-based survey study was carried out to obtain information from a total of 650 small holder farmers. The study was conducted in three local municipalities in Oliver Reginald (OR) Tambo District Municipality of the Eastern Cape Province of South Africa. Descriptive statistics, partial factor productivity, gross margin analysis, household food insecurity access score (HFIAS), ordinal logistic and linear regression were the analytical techniques used in establishing correlations among variables. Results obtained from the survey indicated that under mono-cropping system, Genetically Modified (GM) maize variety was highly productive with an average yield of 1.9 t/ha whilst, improved OPV maize variety was productive (with an average yield of 1.6 t/ha) under mixed cropping system. Furthermore, GM maize (GM = -R418.10), and landrace (GM = -R1 140.29) maize varieties had negative gross margins whilst, conventional hybrids (GM = R5 181.21) and improved OPV (GM = R1 457.41) were profitable. There was a significant and negative correlation between use of GM maize variety and reduction of household food insecurity. GM maize varieties, improved OPV, white maize, white as well as yellow GM maize varieties had a significant impact in reducing household food insecurity; whilst using more than one variety of maize (landraces and GMO) positively influenced household food insecurity. In light of these research findings, it is recommended that, there is need to address household food security by growing improved OPVs under a mixed cropping system and GM maize under monocropping system.

- Description: The aim of this research study is to explore the subjective views and experiences of black men who were perpetrators of domestic violence and have gone through a rehabilitation programme as a result. This paper also explores the connection between masculinity and domestic violence, and how perpetrators make sense of the concept of domestic violence and abuse. The reason underlying the study is to contribute to the fight against domestic violence, perpetrated by males, by understanding the root cause of the problem. This topic emerged due to the lack of sufficient academic papers on men as perpetrators of domestic violence, therefore the intention is to progressively close the gap and contribute to the already existing knowledge on the issue of domestic violence. The study comprised of four research participants gathered from different NGOs and thus different backgrounds. The sample comprised of two Black males and two Coloured males. It is worth noting that for the purpose of this study, black men refers to all men of colour. Thus, both African males and Coloured males fall under the same umbrella of Black men. An Interpretive Phenomenological Analysis from the Qualitative paradigm was used to analyse the data received from semi-structured interviews. The themes that arouse from the study were 1) Learning gender roles through observation; 2) Masculinity learned through teachings; 3) Misinterpreting African values; 4) Intoxication makes it easier to hit a woman; 5) Difficulty dealing with deep emotions; 6) Control and ownership in the relationship; 7) Gender roles forced by society; 8) Lack of consequences; and 9) Masculinity matures. The findings of the study is that masculinity is connected to men perpetrating domestic violence through misinterpreting African values that are taught by elders. Even though masculinity is taught to boys at a tender age, it was discovered that for some of the participants, masculinity is not stagnant but rather constantly changing as the individual grows in personality and life experiences, and thus their values change. As a result of this discovery, masculinity is also individualistic. These findings could assist in future research. Perhaps a much larger research focusing on evaluating, and later, developing rehabilitation programmes that speak to the individual experiences and beliefs of different South African males in order to accommodate the diverse cultures, and thus the beliefs that South Africa shares amongst its people.
