Sustainable agriculture is vital for food security and environmental conservation in Sub-Saharan Africa (SSA), where smallholder farmers encounter challenges like limited resources and market access. E-commerce platforms offer potential solutions by enhancing connectivity and sustainable practices. This review assesses the impact of such platforms on smallholder agriculture in the region, analysing the literature, reports, and case studies from 2010 to 2024 sourced from databases like Google Scholar and Scopus. Inclusion criteria focused on market access, economic outcomes, and sustainability. Findings indicate that e-commerce platforms notably improve market access, leading to better prices and reduced post-harvest losses. They also facilitate information flow, encouraging sustainable practices. However, challenges such as digital literacy and infrastructure deficits persist. E-commerce platforms positively influence sustainable agriculture in SSA by improving market access and supporting sustainable practices. Overcoming barriers through policy interventions and capacity-building is crucial for maximising these benefits. Further research is needed to explore long-term impacts and scalable models.

Indigenous and traditional food crops (ITFCs) are essential to initiatives aimed at increasing food and nutrition security and diversifying the food supply. Therefore, this study sought to evaluate the benefits associated with ITFCs, particularly for food security. The Vigna subterranea (Bambara groundnut), Vigna unguiculata (Cowpea), Colocasia esculenta (Taro), and Sinapis arvensis (Wild mustard) are examples of indigenous crops that were introduced for food security in Southern Africa. This review assessed the advantages of indigenous crops for food security and examined literature, reports, and case studies from 2009 to 2024 using academic databases, like Scopus, Web of Science, JSTOR, Google Scholar, and AGRIS, to assess how indigenous crops impact on food security and the benefits thereof. The primary inclusion criteria were nutritional, economic and environmental impacts of these indigenous crops for food security in Southern Africa. The review concludes that maximizing these benefits requires removing obstacles through capacity-building and policy reforms. The need to integrate precision agriculture to increase production of indigenous crops should be considered and the coherent use of food crops associated with food security must be developed by the government. A comprehensive strategy centered on investment in sustainable farming and climate smart agriculture is recommended to ensure food security.

The semi-arid and dry regions of South Africa experience shortages of water resources, which poses major challenges to livelihoods exacerbated by climate change. Despite the importance of indigenous food crops in optimizing water conservation, limited research has been conducted on effective strategies for promoting indigenous crops. This paper explores the potential of indigenous crops in optimizing water conservation in South Africa. This review paper adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist to ensure transparency, rigor, and reproducibility. A comprehensive literature search was conducted across several databases, including Scopus, Web of Science, and Google Scholar. This review found that indigenous crops, such as sorghum and cowpeas, have innate traits that enable them to flourish in environments where water resources are limited. According to the findings of this study, these indigenous crops are resilient to drought and optimize water use efficiency. This review recommends the creation of a national database for indigenous climate-resilient food crops, which can act as an information hub for research and development. In maximizing the water use efficiency of indigenous crops, sustainable water management techniques remain critical. The results of this study have important implications for sustainable agriculture and water conservation in South Africa.

Building resilient and sustainable food production systems is a major challenge in Sub-Saharan Africa (SSA) due to environmental, climatic, and economic pressures. Farmers in the region must adopt effective adaptation strategies to maintain productivity and contribute toward achieving the United Nations’ Sustainable Development Goal 2, “Zero Hunger.” Among these, water scarcity adaptation strategies are critical for building resilient food systems that also address poverty reduction. However, various obstacles hinder their widespread adoption, and documentation on these strategies remains fragmented. This paper examines available water scarcity adaptation strategies, the opportunities and challenges faced by farmers, and the policy and infrastructure implications for sustainable food production. The findings highlight the essential role of Indigenous Knowledge Systems (IKS) in adopting these strategies. IKS supports natural resource conservation, promotes inclusive market participation, strengthens institutional frameworks, and improves resource-use efficiency under climate stress. The paper recommends further research on transferring Indigenous Knowledge to future generations and exploring the role of policy in preserving and promoting IKS, especially within the SSA context. Emphasizing Indigenous Knowledge is crucial for creating sustainable, resilient agricultural systems that can thrive amid the region’s growing environmental challenges.

The precipitation pattern in South Africa is unpredictable and irregularly distributed across the nine provinces. Water resources support agriculture, mining activities, and other social and economic activities in the country. Nevertheless, South Africa is a water-scarce country prompting the urgent need for revitalization to increase water availability. There are major issues with irrigation water security in South Africa’s agriculture sector. Water scarcity, exacerbated by population growth, climate change, and wasteful use, threatens smallholder farmers’ livelihoods. Smallholder farmers encounter difficulties obtaining water despite initiatives to enhance water management, such as poor infrastructure, a lack of funding, and exclusion from choices about water management. This study examines the current water security challenges faced by smallholder farmers in ensuring water security in South Africa. It emphasizes the importance of collaborative networks, inclusive water governance, and innovative irrigation technologies. The study highlights the need for programs and policies that promote cutting-edge irrigation technologies and support smallholder farmers’ participation in water management decisions. Effective solutions require a coordinated approach, involving government, NGOs, and the private sector. Addressing these challenges can improve water security, promote sustainable agricultural development, and enhance food security nationwide effectively and efficiently. Additionally, the study suggests that context-specific solutions be developed, considering the requirements and difficulties smallholder farmers face. This entails funding irrigation infrastructure, assisting and training farmers, and advancing water-saving innovations.

Climate-smart agriculture (CSA) is a transformative approach to farming that aims to meet the demands of increasing food production under the growing pressures of climate change. CSA’s goals are to boost agricultural productivity, enhance resilience to climate impacts, and reduce greenhouse gas emissions. Thus, the study explored farmers’ socio-demographic factors influencing the adoption of CSA in sustainable crop production. The study was carried out in Bushbuckridge, Mpumalanga province of South Africa, with a focus on smallholder crop producers in the area. The study surveyed 300 smallholder farmers and employed simple random sampling, structured questionnaires, and a binary logistic regression model for data analysis. The significant and positive socio-demographic variables relevant to the adoption of climate-smart practices were level of education (p < 0.014), household size (p < 0.007), farm experience (p < 0.053), and farmland fertility (p < 0.047). Therefore, for CSA practices to be adopted by smallholder crop producers, a targeted approach is needed to address this issue. Therefore, support and training are needed to bridge the literacy gap among smallholder crop producers with the overall aim of improving their understanding of climate change and CSA practices that can mitigate the effects of climate change.
