Vegetables are key to nutrition and economic security, especially for developing societies. Research in vegetables has been historically key. From early domestication efforts to modern-day breeding and value addition, research has enabled vegetable productivity to support the nutritional and economic needs of societies. Impactful research, however, requires competent research capacity and a guiding framework, in a continuously changing socio-climatic world. Vegetable research appraisal in Malawi, especially regarding capacity, focus, and a guiding framework, is lacking.

Agricultural productivity impacts the environment and natural resources in various ways. The severity of these impacts has triggered the emergence of natural resource management and the related, highly criticized science of agroecology. Vegetable production has known environmental impacts. However, the extent of its participation in sustainable production has not been adequately explored. This review sought to explore the spaciotemporal position of vegetables in a suite of existing sustainable agricultural practices, explore regional variations and discover lessons that can guide the future of vegetable production. There are regional differences regarding sustainable production practices and the associated barriers to their adoption. Generally, sustainable agricultural practices with a societal history in a region tend to be successful, unlike when they are “new” innovations. The major barriers to sustainable agricultural practices in vegetable production are economy-related (total investment cost) and crop-related and are also related to the technology transmission approaches. Unfulfilled expectations and a lack of community participation in technology development are noted challenges, which have led to dis-adoption. A farmer-centered approach to technology promotion could help. Comparatively, southern Africa has the most challenges in the adoption of sustainable agricultural practices. From the lessons learned from other regions, agroecology in vegetable cultivation is not unachievable in Africa. The projected challenges mean that sustainable vegetable production is inevitable.

Casual wage labour (known as ganyu in Malawi) is a widely adopted strategy to cope with insufficient income and food production in rural households. Although previous studies have discussed the magnitude of the contribution of ganyu to rural livelihoods, the actual conditions of individual rural households have not been studied in detail. The current research conducted a detailed village-level case study to analyse the relationship between ganyu and rural livelihoods in Malawi. The characteristics of three categories of households were examined: those that engaged in ganyu, those that employed ganyu, and those that engaged in and employed ganyu. The study found that: (1) income from ganyu and its contribution to household food security differed considerably based on age, gender, household circumstances, and local conditions; (2) households that employed ganyu were not necessarily wealthy or achieved self-sufficiency in maize production; and (3) contradictory behaviour of a household to engage in and employ ganyu was a result of the context-specific needs of that household. Rather than viewing ganyu as poorly paid agricultural wage labour, the study propose acknowledging that each household has its own rationale for engaging in or employing ganyu. Such an understanding from a household-level perspective would better inform poverty and food security policies.
