In South Africa, maize is grown all over the country under various environments including both dry and irrigated agriculture. The majority of maize farmers are smallholders farming on small pieces of land with low input technologies. Additionally, South Africa`s smallholder maize farmers are characterised by low maize productivity, this is despite of the availability of many improved maize varieties on the market. It is clear that professional maize breeders are continuously developing many superior maize varieties with traits more suitable for the commercial farming sector than the smallholder sector. Against this background, this study used a descriptive statistics approach to find out maize varieties and traits preferred by smallholder farmers. The study also evaluated factors that influence smallholder farmers` maize varietal selection choice using descriptive statistics and multinomial regression. The data used for the empirical analysis was obtained from a survey of 200 smallholder farmers in Mhlontlo Local Municipality, in the Eastern Cape Province of South Africa.

Lack of access to agricultural extension and advisory services is one of the major challenges facing emerging farmers in South Africa. The purpose of the study was to determine the level of access to extension and advisory services by emerging livestock farmers in uThungulu district municipality of KwaZulu Natal province. A survey design of face-to-face interviews was used to collect data using a structured questionnaire. A sample of 1 437 was randomly selected from 4 792 emerging livestock farmers in the district. A sampling fraction of 30% was used. Stratified sampling was used to determine the number of participants from each local municipality. The survey was conducted with different groups of emerging livestock farmers representing different age groups ranging from 18 years of age and older. Descriptive statistical analyses were performed using the Statistical Package for the Social Sciences (SPSS) version 23 software. The results showed that more than 90% of emerging livestock farmers in the district had better access to public extension compared with 14% who had access to private extension. On average, 30% of the respondents indicated that they also had access to extension and advisory services from agricultural cooperatives. With regard to extension delivery approaches, advisory was the main (43.5%) extension approach practised in uThungulu district municipality followed by project approach (37.8%), participatory approach (36.4%) and technology transfer at 11.1%. In conclusion, the involvement of private sector and cooperatives in rendering agricultural extension and advisory services in the emerging livestock sector was an indication that various stakeholders collaborate in the improvement of agriculture in the province. The emergence of project approach showed that extension agents or officers have become more target oriented rather than technology transfer driven. The use of participatory extension approach indicated that in the 21st century, farmer’s opinions were also taken into consideration in the delivery of agricultural extension and advisory services in the emerging livestock sector. It was recommended that there should be a wider partnership of extension and advisory services involving various stakeholders such as farmers, municipalities, non-governmental organizations and the private sector, to address and boost the efficiency of services to farmers in South Africa. Therefore, more work is required to increase access to extension and advisory services through cooperative associations by organizing emerging farmers in cooperative associations for the participatory approach to succeed / Agriculture, Animal Health and Human Ecology / M.

The Garden Route is situated between a mountain range and the ocean, both within close proximity. These geographic considerations make the farmers in the area vulnerable to extreme weather events, especially droughts and floods, which have been experienced in recent years. Agriculture in the area is predominantly focused on dairy and vegetables, which require intensive irrigation practices. It is this water demand that inspired adaptations to counteract the risks of extreme weather and dwindling water sources. These adaptations and behaviours were investigated to determine the underlying perceptions and influences. The research aimed to understand the way environmental knowledge would disseminate through the use of the Diffusion of Innovation theory, whilst determining the ecological worldviews of the participants through the use of the New Ecological Paradigm (NEP) scale. Both of these theories proved effective in researching the ecological perceptions of and various influences on the participants, with a few minor drawbacks. The data analysis investigated the research questions with a three-pronged approach. Interpersonal interviews and media content analysis of the local and agricultural media in the area was followed by analysing the two sets of findings, in order to find overlaps and relationships between the factors explored. The interviews were designed as semi-structured to allow for themes to emerge and were conducted mainly within the diary and beef industries, consisting of 24 participants. The media content analysis incorporated a niche agricultural magazine (32 articles) as well as the local newspaper (74 articles). The articles were coded for themes to allow for comparison between the two, and to provide an overall understanding of the media coverage. The use of the interviews and media content analysis concurrently, made it possible to determine the farmers’ perceptions of water conservation and the possible influences on these. By exploring this, the research endeavours to understand the dynamics between the farmers’ use of media and interpersonal networks and their water conservation practices. The farmers’ perceptions appeared to be predominantly shaped by agricultural media and interpersonal communities. The NEP scale responses exposed the clash between economic and environmental considerations. The farmers were acutely aware of their ecological impact and were employing various measures to counteract it. However, these were heavily dependent on their financial situation. This is in contrast to the NEP scale’s measuring of NEP statements contrasted with Dominant Social Paradigm (DSP) statements to determine ecological attitudes. These findings confirm previous research and demonstrate that modern farmers are more likely to adopt conservation practices than their traditional counterparts, if it helps achieve their economic, social and environmental goals. The importance of the historical context of South Africa’s water issues emerged, with the past and future proposed changes to water regulation and legislation affecting farmers’ perceptions. The move from agriculturally privileged water legislation to equitable distribution is affecting the farmers negatively, causing distrust towards the government. The research was successful in achieving an understanding of the effect of the mass media and interpersonal communication influences on the farmers’ perceptions of water conservation.
