- Description: The fast track land reform program (FTRLP) of 2000 in Zimbabwe resulted in a dynamic change of Zimbabwe’s agricultural landscape. It resulted in the conversion of white owned commercial farms into resettlement models A1 and A2. Model A1 was intended to decongest communal areas and was targeted at land-constrained farmers in communal areas. Model A2 on the other hand was a commercial settlement scheme comprising small, medium and large scale commercial settlement, intended to create a cadre of black commercial farmers. This model was in principle, targeted at any Zimbabwean citizen who could prove farming experience and/or resource availability and was based on the concept of full cost recovery from the beneficiary (Musemwa, 2011) This study looked at the demographic that constitutes of commercial tobacco farmers, in Zimbabwe after the FTLRP, how they are affected by climate change and variability and how they adapt to these climate extremes; in particular, their uptake of crop insurance. The study was quantitative and utilised a structured pre-coded questionnaire to interview 158 farmers that are into commercial tobacco farming in Manicaland, Mashonaland Central, Mashonaland West and Mashonaland East Provinces of Zimbabwe. The focus was on two central themes. The first was an investigation of the commercial tobacco farmers’ vulnerability to climate change and variability in Zimbabwe. The second theme analysed the factors influencing the farmers’ adoption of crop insurance and the challenges faced by both the farmers and insurance companies in its adoption. Three approaches were used to address the above objectives. Firstly to analyze the vulnerability of commercial tobacco farmers to climate change and variability, the integrated vulnerability assessment approach using vulnerability indicators from four tobacco producing provinces in Zimbabwe was used. The vulnerability indicators used included a series of different socio-economic, institutional and biophysical attributes which were further categorized into three classes, based on the Intergovernmental Panel on Climate Change’s (IPCC 2001) definition of vulnerability, which consists of adaptive capacity, sensitivity and exposure. The LV Index and LVI-IPCC Index (Ms Excel) were then used to determine the farmer’s vulnerability index. Secondly, descriptive statistics were used to determine the manner in which farmers have been adapting to climate change and variability and lastly, the study used the binary logistic regression model to determine factors that influence the adoption of crop insurance by these farmers. The results from the analysis show that the net effect of exposure, sensitivity and adaptive capacity is moderate for the provinces of Mashonaland East, Mashonaland Central, Mashonaland West and Manicaland. Through the LVI Index and LVI-IPCC index, the study found indices of 0.566 and 0.100 respectively showing that the commercial farmers in these provinces are moderately vulnerable to the effects of climate change and variability. The factors that contributed the most to this vulnerability were aspects of finance, knowledge and skills, support services, and the state of the environment. In terms of adaptation, the majority of farmers indicated that they were aware of climate change and were aware of increased climate variability and had observed an increase in temperature and rainfall variability. The different ways in which the farmers adapted included, off-farm income, enterprise diversification, irrigation, crop rotation, conservation tillage practices, establishing woodlots and using alternative fuel for curing such as coal. The binary logistic regression model showed that the factors that were significant with a positive effect on the uptake of crop insurance are; subscription to contract farming which was the major determinant, access to crop insurance information, farm tenure and area under tobacco. Factors that had a significant but negative effect, and led to a reduction in the uptake of crop insurance were level of education, perception of crop insurance premiums and enterprise diversification. The farmers were found to be highly diversified either with off-farm income, crop diversification and or enterprise diversification. The study recommended that the farmers should promote sustainable development through their production activities and adaptation strategies adopted to increase their resilience to climate change and variability. Strengthening of social networks and institutional capacities was also recommended to; increase bargaining power, for information dissemination and provision of technical support and extension services to enable the farmers to take on appropriate measues to reduce their vulnerability. In terms of crop insurance uptake, the study recommended improvement in the dialogue between the farmers and insurance companies, and periodic training and education of farmers to improve knowledge and encourage uptake.

- Description: The study reviews the household’s perceptions and determinants of sustainable products harvesting. Communal rangelands are vast natural landscapes in the form of grasslands, shrubs, woodlands, wetlands and deserts with multiple functions to the rural households. Most rural communities share boundaries and interact with rangelands for multiple socioeconomic and environmental reasons. Since most of these interactions are external to the price mechanism, the actual contribution of rangelands to communities has largely been missed. In an effort to appraise and explore the communal rangeland contribution to households, a study from Dyamala community in the Raymond Mhlaba Local Municipality under Amathole District in Eastern Cape was conducted using cross-sectional data. Descriptive results revealed that the majority of the respondents (71 percent) from the study area positively perceived communal rangelands as safety nets. however, there also emerged a fair share of challenges namely, (bad spirit, host predators, compete with arable land) leading to negative perceptions towards communal rangelands. It was also evident that, the majority of respondents from the study area use communal rangelands for fuel wood, construction poles, traditional medicine, with minor harvests of wild food (flora and fauna) and thatch grass. The results of the study also revealed that, rural people depend more on social grants for their income followed by incomes from remittances, agricultural activities and communal rangelands. However, it was established from the results that though communal rangelands provided commercial products capable of generating household income, rangeland users trading such products were receiving meagre incomes. This might be caused by the lack of institutional support to rural households thus, the low incomes received from communal rangelands. To that effect, main communal rangeland products such as, fuel wood, poles and medicine were cited as being more valuable for local domestic use than for the external market. Regression estimates further indicated that participation in communal rangeland products harvesting is more conditioned by perception-related factors as compared to socioeconomic attributes of rural households worth understanding for strategic targeting to promote their conservation. The extant literature and the study results, evidently show that communal rangelands provide a livelihood among rural households although it has a low direct household income potential. Therefore, the respondents were of the view that the use of campaigns targeting several perceptions (such as communal rangelands act as a source of medicinal plants, arable land and income etc) as suggested by the regression estimates may be very useful. The support from the extension department and further research may be necessary for purposes of quantifying harvestable rangeland products capable of enhancing rural livelihoods. Moreover, the observed low income potential of communal rangeland products suggests several technical and institutional challenges worth addressing to promote value addition of rangeland products.

- Description: Smallholder farmers have been growing food in their communities, but some are still food insecure. Therefore, appropriate food systems are very important for smallholder farmers’ self-reliance as well as food and nutrition security. The study focuses only on community and regional maize food systems for rural households. The main aim of this study was to investigate the regional and community food systems for smallholder maize farmers in Mqanduli. The objectives of the study were to profile smallholder maize farmers, describing the existing maize food systems and patterns in Mqanduli and also to determine factors that influence farmers’ participation in local or regional markets. Availability or convenient sampling and random sampling techniques were used to collect primary data from smallholder maize farmers. Descriptive statistics was used to profile smallholder farmers, as well as, in describing the existing maize food systems at Mqanduli. The binary logistic regression model was used to analyse the variables that had influenced the smallholder famers’ participation in markets. Descriptive results revealed that, smallholder maize farmers in Mqanduli are characterised by high participation in both local and regional markets. Moreover, they utilized both community and regional food systems. Logistic regression results indicated that, out of 11 variables included in the analysis as factors influencing farmers’ participation, 6 of them (age, level of education, market information, distance, access to credit and extension visit) were found to be significant and 5 (gender, amount of land, transport availability etc) were not significant. However, access to credit and distance were found to be the most significant variables, showing a positive relationship to smallholder maize producer`s market participation. Therefore, it was recommended that, there must be more investment in research by government and policy makers when it comes to food systems especially in rural areas, to enhance smallholders’ livelihood. More access to credit is also needed by farmers in order to be able to market their produces.

- Description: Different maize varieties are produced by smallholder farmers in Eastern Cape Province in different agro ecological zones. Government cropping programmes have been promoting the production of GM maize varieties by smallholder farmers to enhance food security. However, there is no evidence to show how smallholder farmers are selecting the maize varieties they want to produce. On the other hand, smallholder farmers are slowly adopting GM maize due to number of factors affecting them. The study adopted Cross sectional design to collect the data from smallholder farmers from the three study sites. The sample size was 704 respondents. A semi structured questionnaire was used to collect primary data from smallholder farmers in Mqanduli (Lowest rainfall), Flagstaff (moderate rainfall) Port St. Johns LM (highest rainfall), under OR Tambo DM. Multistage sampling was utilised. SPSS version 24 was used to analyse descriptive statistics and Multinomial logistic regression model. STATA version 13 was used to analyse Crag’s double hurdle model. The results showed that, farmers were producing GM maize (Ht and Bt), unimproved OPV (landrace) and improved OPV (Sahara). The majority of farmers were producing OPVs. The findings further showed that, the selection of GM maize varieties is positively related to maize threat stalk borer damage. The results indicated that, most of the respondents were not aware of the GM permit conditions thus, they failed to comply with the expected conditions. The following variables influenced the adoption and intensity of adoption of GM maize: gender, highest educational level, household size, employment status, access to land, access to market, access to credit, membership to farmers group, main source of income, farm size, and access to extension services. It was concluded that from the three study areas different maize varieties were produced. Adoption of GM maize was influenced by the number of factors. GM maize permit condition were not met by smallholder farmers. It was recommended that, research should be done on OPVs which are the most preferred varieties by smallholder farmers. Extension officers and those who are adopting GM maize should be educated and trained about GM maize permit conditions.

- Description: The acceptability of zero tillage amongst small-scale farmers is a challenge in the Eastern Cape Province as farmers have different strategies on how to manage residue. This situation is due to the limited information available on the benefits of implementing zero tillage, such as improving soil health. The Department of Agriculture and Agrarian Reform have been assisting small-scale farmers by subsidising them with the latest innovations, such as zero tillage. The main essence of these initiatives was to compensate farmers that are previously disadvantaged as a result of the apartheid system prior to 1994. Zero tillage has recently gained more attention as one of the most important farm practices due to its benefits for soil conservation and the elimination of greenhouse gases. The study was conducted at Magadla and Nkawu villages in Matatiele, Eastern Cape. The objective of the survey was to examine the influence of current residue management practices amongst Matatiele farmers in the light of the adoption of zero tillage practices. The data was collected using questionnaires and group discussions. The statistical package SPSS and Microsoft Excel were used to analyse data. The findings showed that the adoption percentages of zero tillage by small-scale farmers was 34 percent and 65 percent in Magadla and Nkawu villages respectively. Amongst the challenges that non-adopters faced were shortage of inputs, weak communication channels between farmers and coordinators, residue benefits to livestock and lack of proper monitoring and evaluation. Binary logistic model was adopted and used to analyse 13 independent variables that influence the adoption of mulching in the study area.
