The transformation of smallholder farming is poised to be one of the key drivers of achieving the dual objectives of food security and poverty reduction in Sub-Saharan Africa (SSA). Smallholder farmers account for between 60–80% of the food produced in the region but face many challenges that impede their productivity. Such challenges include a lack of timely access to appropriate agricultural information and services, which results in poor decision-making, particularly in addressing challenges and responding effectively to opportunities. In that context, the effective use of Information and Communication Technologies (ICTs) in improving accessibility to appropriate agricultural information and services presents substantial prospects for transforming the productivity and livelihoods of the farmers. Currently, the region experiences massive penetration and propagation of mobile and web-based applications. However, there is a dearth of compelling, comprehensive reviews evaluating their importance in enhancing agricultural information and services dissemination to smallholder farmers. Therefore, the current review explores the potential of enhancing agricultural information and services dissemination to smallholder farmers through ICTs and highlights gaps in their development and deployment in SSA. Five existing mobile applications used to disseminate agricultural information and services to smallholder farmers were identified, and their advantages, limitations, and opportunities were discussed. These were Esoko, iCow, Community Knowledge Workers, WeFarm and DigiFarm. The development and deployment of user-driven mobile applications that provide curated skill-sharing platforms, encourage farmers to give feedback to extension systems in real-time and promote the participation of women and youth in agriculture are recommended.

The creation of commercialization opportunities for smallholder farmers has taken primacy on the development agenda of many developing countries. Invariably, most of the smallholders are less productive than commercial farmers and continue to lag in commercialization. Apart from the various multifaceted challenges which smallholder farmers face, limited access to extension services stands as the underlying constraint to their sustainability. Across Africa and Asia, public extension is envisioned as a fundamental part of the process of transforming smallholder farmers because it is their major source of agricultural information. Extension continues to be deployed using different approaches which are evolving. For many decades, various authors have reported the importance of the approaches that effectively revitalize extension systems and have attempted to fit them into various typologies. However, there is a widespread concern over the inefficiency of these extension approaches in driving the sustainability of smallholder farming agenda. Further, most of the approaches that attempted to revolutionize extension have been developed and brought into the field in rapid succession, but with little or no impact at the farmer level. This paper explores the theory and application of agricultural extension approaches and argues the potential of transforming them using digital technologies. The adoption of information and communication technologies (ICTs) such as mobile phones and the internet which are envisaged to revolutionize existing extension systems and contribute towards the sustainability of smallholder farming systems is recommended.

The drive to hasten the development of smallholder livestock farming through research-extension-farmer-input linkage systems (REFILS) is being promoted in African countries. Resource-constrained smallholders face various challenges including poor access to timely and relevant research-based innovations. Weak research-extension-farmer-input linkages exacerbate this issue. This review explores the evolution of Knowledge Transfer and Agricultural Extension Theories, emphasising the shift from centralised top-down dissemination to participatory and user-driven models. The paper characterises “research”, “extension”, “farmer”, and “input” as the main pillars of agricultural knowledge systems and how their lack of interconnectedness impacts their effectiveness. Examining the dynamics of these pillars provides a comprehensive rationale for strengthening REFILS. Also, REFILS adoption disparities such as limited funding and investment, institutional and organisational inefficiencies, and social and cultural factors were discussed. The identified key challenges form an intricate web of interconnected issues which should not be addressed in isolation but collectively. The proposed measures for REFILS enhancement include building strong public-private partnerships, full participation and collaboration by all key actors including farmers, digitalisation of smallholder agriculture, and policy and institutional reorganisation towards a stronger REFILS. Moreover, the study acts as a foundational guide for strengthening REFILS at national, regional, and continental levels to foster economic, environmental, and social sustainability in Africa’s livestock industry.

The opportunity for the smallholder beef farming system to support the growth of South Africa’s livestock industry is untapped. Slow growth of the sector is attributed to many limitations that affect the smallholder beef farming sector. The objectives of the current study were to identify and characterize the systemic challenges and constraints that confront market-oriented smallholder beef farmers in the Limpopo Province, South Africa. Data collection involved interviewing all the 62 farmers under the Limpopo Industrial Development Corporation (IDC)-Nguni project using structured questionnaires. The sample was predominantly males (87%) and adults aged over 45 years (88%). Close to half (47%) of the respondents had tertiary education. Major ecological and production challenges reported as percentages of respondents were drought (96%), rangeland degradation (94%), diseases (89%), feed shortage (86%), and inadequate water (82%). Nearly 50% of the respondents ranked the extent of these challenges as high to very high. Results indicated that poor access to finance, lack of infrastructure, and poor access to markets were some of the key limitations reported by more than 80% of the respondents with above 50% ranking them as high to very high. Logistic regression models showed that respondents’ perceptions to the majority of the challenges were largely influenced (p < 0.05) by education, access to formal training, farm size, and age. Given all the limitations found, current findings point to the prospects of designing strategies that support knowledge flows and capacitating the farmers with skills to combat the challenges.

A survey was conducted to identify management information sources and communication channels used by commercially oriented smallholder beef cattle producers (n = 62) in Limpopo province, South Africa. A total of 62 commercially oriented smallholder farmers under the Limpopo Industrial Development Corporation-Nguni cattle project were interviewed using a structured questionnaire to collect data. Descriptive statistics were used to analyse data on farmers’ demographic and farm characteristics, sources of information and communication channels used. A multinomial logistic regression model was used to evaluate factors that influenced farmers’ choices of information sources and communications channels used. Findings show that government extension (53% of the respondents) and other farmers (30%) were the major sources of management information for the farmers. Based on the logistic regression results, the decision to choose government extension as the main source of information was mainly influenced by respondents’ gender (p = 0.001) and access to training (p = 0.023). Communication was mainly through farm-to-farm visits (56%) and the use of mobile phones (30%). Based on the current findings, the infusion of modern information communication technologies such as mobile phone-based innovations with the existing government extension service could further strengthen the capacity of farmers to share information among themselves as well as providing feedback to extension agents. Furthermore, it is essential to take cognizance of farmers’ socio-economic factors when identifying and characterizing their management information sources and communication strategies.

Pig genetic resources in Africa originate from different regions and were introduced through several migration pathways. Genetic analysis has shown a strong phylogeographic pattern, with pigs on the eastern parts showing a high frequency of alleles from the Far East while the ones on the western parts show a strong European influence. This highlights the influence of trade routes on the genetic legacy of African pigs. They have, however, since adapted to the local environments to produce unique populations with unique attributes. Most of the pigs are now reared in resource-constrained smallholdings under free-range conditions. They are largely owned by women who spread ownership of the resource through kinship networks. Very little work has been done to characterize, conserve, and sustainably utilize pig genetic resources in Southern Africa. The risk status of the breeds together with population numbers, distribution, and other attributes are largely unknown. This paper proposes several strategies for the sustainable utilization of the pig genetic resources: A market-driven in situ conservation program and two complementary ex situ strategies. In addition, the possibility of community-based breed improvement programs is discussed. It was concluded that genetic characterization of domestic free-range pig populations should be a supreme priority.
