South Africa, a main food exporter in SADC, is characterised by a dual agricultural economy consisting of a well-developed commercial sector and smallholder, often subsistence, farming. Using the Ricardian cross-sectional framework, we examine the impact of climate change on a nationwide sample of crop, horticulture, livestock and mixed commercial farming systems. We find that a simultaneous decrease in precipitation and an increase in temperature will reduce productivity; and that an increase in temperature alone negatively affects farm output more than a decrease in precipitation. One of the most robust findings is the difference in the extent to which different commercial production systems will be impacted. That is, the results indicate that the strongest impact will be amongst specialised commercial crop farming system. In contrast, mixed farming systems appear to be the least vulnerable. This finding is consistent with studies on small-holder farms in sub-Saharan Africa. Hence, it appears that despite the likely benefits derived from economies of scale, commercial farms are, somewhat, equally vulnerable to climate change. Further, a province-wise assessment revealed that areas that already face disadvantageous climatic conditions will become even less productive. Overall, the findings suggest that practicing mixed farming methods will strengthen the resilience of commercial farms to climate change and that access to extensions-insurance and irrigation-is likely to reduce the risks.

Summary With the ongoing changes in climate, household food insecurity is likely to be more widespread in most small-holder and subsistence farm households in sub-Saharan Africa. However, the existence and extent of gendered household food security—or lack thereof—remains unclear. This study extends existing knowledge by assessing gender inequality in household food (in) security among small-holder farm households in urban and rural areas of South Africa. In doing-so, we use the gender of the head of household and treatment effects framework. Our results show that male-headed households are more food secure compared to female-headed households, with the latter depending more on agriculture to increase household food levels. We further find that the household food security gap between male- and female-headed households is wider in rural than in urban areas, where rural male- and female-headed households are more likely to report chronic food insecurity, i.e., are more likely than their urban counterparts to experience hunger. Interestingly, the effects of climatic characteristics on household food security are more apparent in rural than in urban areas. Our findings suggest that household food security initiatives are likely to be more effective, in closing the gender gap in household food security, if aligned with policies on urban and rural agriculture and development.

This paper examines the impact of agriculture-related shocks on consumption patterns of rural farming households using 3 years of data from South Africa. We make two key observations. First, agriculture-related shocks reduce households' consumption. Second, natural resources and informal social capital somewhat counteract this reduction and sustain dietary requirements. In general, our findings suggest the promotion of informal social capital and natural resources as they are cheaper and more accessible coping strategies, in comparison to, for example, insurance, which remains unaffordable in most rural parts of sub-Saharan Africa. However, a lingering concern centres on the sustainability of these less conventional adaptation strategies. [ABSTRACT FROM AUTHOR]

This paper examines the impact of climate change on poor households across South Africa who practise subsistence farming to supplement their household income and dietary requirements. We consider three production systems: specialized crops, livestock and mixed crop-livestock farming. In general, we find specialized crop farmers to be the most vulnerable, while mixed crop-livestock farmers appear to be least vulnerable, suggesting that crop-livestock diversification is a potential coping strategy among poor subsistence farming households. We observe qualitatively similar results when we use self-reported food adequacy as the outcome. Furthermore, predicted impact shows that the climatic changes will be mildly harmful at first but will grow over time and lead to a 151 per cent loss in net revenue by the year 2080. Interestingly, we observe that crop farmers receive higher revenue when land is owned by the household, while on the other hand, livestock farmers earn more revenue when the land is communal.
