Climate change poses a significant threat to global agriculture, particularly for small-scale farmers who often lack the resources and knowledge to adapt. Without effective coping and adaptation strategies, agriculture in Africa is likely to suffer, leading to increased poverty and food insecurity. Adaptation to climate change is closely linked to farmers’ awareness of the issue, though the extent of this awareness in South Africa remains unclear due to conflicting previous studies. This study aimed to investigate the relationship between climate change awareness, adaptation strategies, and food security among small-scale farmers in the Eastern Cape Province, with the aim of understanding how farmers’ awareness of climate change influences their adaptation decisions and the subsequent impact on agricultural productivity and food security. The study used quantitative analysis to examine the relationship between climate change knowledge, adaptation, and food security. Multi-stage sampling was used to collect data from 200 small-scale farmers through semi-structured questionnaires. Logit regression and endogeneity switching regression were applied for data analysis. The study finds that small-scale farmers in the province are fully aware of climate change and have experienced its negative impacts, especially reduced farm returns (38%) and yields (36%), which threaten agricultural productivity, food security, and farmers’ economic viability. In response, farmers have adopted various strategies, including crop rotation (22%), using improved crop varieties (20%), changing planting dates (12%), and applying fertilizer or mulching (12%). Key factors influencing adaptation include age, access to climate information, education, market proximity, extension services, drought frequency, temperature and rainfall perceptions, radio ownership, farm income, size, and family size. The study shows that these adaptation strategies have improved agricultural yields and farm returns, positively contributing to food security in the area. Based on the study findings, this study recommends that governments and policymakers implement and provide targeted policy interventions, extension services, and educational programs that can enhance climate change knowledge among small-scale farmers.

Improving profit efficiency in vegetable farming, especially for Spinach, is vital in enhancing income, livelihoods, and nutrition security and reducing the poverty of smallholder farmers, particularly in developing countries like South Africa. Despite the country’s potential, spinach production faces major challenges, including unreliable markets, low adoption of modern production systems, and production inefficiencies that affect farm returns. This has been attributed to a lack of adequate and reliable information to guide producers on measures for improving productivity through cost effective production systems and efficient market systems, eventually leading to profit inefficiency. Therefore, this study sought to assess the profit efficiency of smallholder spinach producers under irrigated agriculture in the Eastern Cape Province, South Africa. The study made use of multi-stratified sampling procedures to select 150 spinach producers under irrigation. The stochastic profit frontier function was applied to assess the profit efficiency of smallholder spinach farmers. The results indicated that most farmers operated in farm sizes of 3 ha with an average age of 48 years. The estimates of the stochastic profit frontier function showed that farm size, cost of fertilizer, seed, and pesticides increased profit while labour used decreased profit. Findings indicated a 10% profit loss due to a mixture of technical and allocative inefficiency in the production of spinach, while farmers were able to attain an average profit inefficiency of 90%. Moreover, findings revealed numerous factors that positively affected the profit efficiency of spinach farmers, including socioeconomic, institutional, and cultural. The study findings imply that profit efficiency can increase significantly through the use of high-quality fertilizer, seeds, and pesticides. The allocative efficiency results indicate that improvement in access to extension services, farmers’ level of education, and farm experience can result in the increased allocative efficiency of spinach farmers in the study site. The study further suggests that smallholder farmers must adopt innovative technology to enhance their agricultural productivity, and this is likely to improve household income and nutrition security. Thus, the study recommends that policymakers and government must invest in farmers’ education through effective extension delivery programs and the provision of credit to help farmers increase their profit efficiency.

The Eastern Cape Province of South Africa is largely rural, with agriculture as the main livelihood for many households. However, the province has a semi-arid climate and reliance on rain-fed agriculture, which makes the region highly vulnerable to climate-related risks, particularly droughts. Smallholder farmers, who play a crucial role in food production and local economies, face significant challenges due to limited access to resources like irrigation, modern technology, and financial support, exacerbating their vulnerability to climate variability. These droughts cause severe losses in agricultural productivity, threatening food security, increasing poverty, and driving rural migration. Despite the potential benefits of adaptation strategies, many farmers lack the tools and knowledge to effectively cope with the increasing frequency and severity of droughts. This study examines how smallholder farmers in South Africa’s Eastern Cape Province perceive, experience, and cope with drought risk and its food and nutrition security implications. Using structured questionnaires, the authors collected data from 160 smallholder farmers and employed statistical analysis techniques, including a multinomial logit model. The study found that smallholder farmers understand drought risk but continue to face high vulnerability to adverse effects such as water scarcity, crop failure, increased disease incidence, and rising temperatures. Socioeconomic and institutional factors significantly influenced the adaptation strategies chosen by smallholder farmers. This study suggests that a combination of localized and modern adaptation approaches, supported by various institutional, policy, and technological interventions, is essential to enhance the resilience of these farmers. Specifically, localized strategies such as using traditional water management systems and crop diversification were effective in addressing region-specific climate challenges. At the same time, modern approaches like climate-resilient crop varieties and early-warning systems provided broader, more scalable solutions. Institutional support measures, such as access to climate information and extension services, policy interventions promoting sustainable practices, and technological advancements in irrigation and seed technologies, were key factors in improving adaptive capacity and reducing vulnerability. There is an urgent need to provide comprehensive support and empower farmers to adapt effectively, protect their livelihoods, and contribute to broader food security and poverty reduction efforts. This study highlights the importance of understanding and addressing the perceptions and experiences of smallholder farmers facing drought risk to ensure sustainable food production, income generation, and poverty alleviation.

The agriculture sector in Africa is dominated by small-scale farmers who account for about 80% of the total farms. However, small-scale farmers are vulnerable to climate change and climate variability. Their high susceptibility to climate change emanates from their inadequate ability to adapt to climate change. As a result, small-scale farmers are generally adversely impacted by climate change due to over-reliance on rainfed agriculture and natural resources. This exposure and susceptibility, however, differ across the regions due to the heterogeneity in topography, climate, access to resources, farmer resilience and adaptation capacity. Therefore, site-specific studies are encouraged to increase the awareness, resilience and adaptation capacity at the local level. The study intends to analyse historical climate (air temperature and rainfall) data from a weather station that has not been employed for climate change studies and project possible future changes in the same climate parameters due to global warming for a localised agricultural community within the sugarbelt region of KwaZulu-Natal, South Africa. The study focuses mainly on air temperature and rainfall changes to inform local farmers about potential climate changes and possible impacts of the projected climate changes on the local agricultural productivity. This study was conducted in the KwaZulu-Natal midlands of South Africa, and the Representative Climate Pathways (RCP8.5 and RCP4.5) climate projection of the CanESM2 model were used for the projection of future air temperature and rainfall trends for the 2020s, the 2040s and the 2080s. According to the results, both minimum and maximum air temperatures will continue to increase for the entire study period. The RCP8.5 results indicate that maximum and minimum air temperatures will reach a maximum range of 1.72 to 3.14 °C and 1.54 to 3.48 °C, respectively. For the rainfall, the model projects a positive trend, although all the scenarios predict a declining trend for the near future (2020s) and an increase in the 2050s. These results indicate that, in the absence of adaptation the risk of small-scale farmers, particularly for sugarcane, which is largely planted in the area, the production losses will heighten and hence increase the likelihood of increased poverty, food insecurity and unemployment.

Climate change is a serious challenge that poses an additional problem to the many existing difficulties in the agricultural sector. It will likely exacerbate an already dire situation by making current production methods less sustainable. Previous studies concluded that most people in developing countries perceive climate change as a spatially and temporally distant threat. However, recent studies have raised a new narrative, suggesting that rural communities are becoming more aware of climate change and variability. The study, therefore, aimed to compare the perceptions of climate change among small-scale sugarcane farmers with scientifically observed climate trends in the study area. The study mainly analysed rainfall and air temperature trends over twenty years and compared these with climate change, as farmers in the study area perceived. Additionally, it assessed whether the participants had implemented adaptation plans to minimise the adverse effects of the observed climate variations, both scientifically and perceptually. The study findings indicate that small-scale sugarcane farmers perceive climate change fairly accurately. Less than half of the small-scale sugarcane farmers (nearly 40%) observed increased temperatures, rainfall, drought frequency, and frost occurrence. Their perceptions aligned with the findings from the scientific data, which indicated that maximum temperature has been increasing at 0.049 oC per annum-1 from 1997 to 2017 while the rainfall showed an increase of 15.475 mm per annum-1 over the same period. These findings confirm that these farmers are becoming more aware of climate change occurring in their communities. However, the study results also show that despite the accurate perception of climate change, farmers struggle to adapt to this accurately perceived climate change. This highlights their vulnerability to climate change due to a lack of adaptive capacity. The study recommends government intervention to facilitate improved collaboration between academics and farmers for information sharing to identify possible adaptation strategies for small-scale farmers.

Global warming is widely recognised, and its effects are becoming apparent throughout the world. Evaporation and evapotranspiration, the key components of the hydrological cycle, are generally expected to increase due to the rise in air and surface temperatures. However, previous studies suggest a decrease in these phenomena despite the observed global warming. The decreasing evaporation and evapotranspiration have been attributed to various factors. In this study, reference evapotranspiration (ETo) trends estimated using the Penman-Monteith method were studied over the KwaZulu-Natal midlands area of South Africa for the period 1997–2017. This study employed the Mann–Kendall test and linear regression model to analyse annual and seasonal ETo trends. In addition, the trends of climate parameters and their contribution towards ETo variation were analysed. The results indicate a generally decreasing ETo trend for most weather stations studied over the study period. The climate variables analysed indicate an average decreasing trend in wind speed, solar irradiance, and relative humidity while average air temperature exhibited no significant change. Relative humidity and solar irradiance were found to greatly influence ETo variation in the study area. We therefore conclude that atmospheric condition studies should consider both local and global climate phenomena to understand the actual drivers of change in any atmospheric factor.
