22 pages, While climate change threatens global food security, health, and nutrition outcomes, Africa is more vulnerable because its economies largely depend on rain-fed agriculture. Thus, there is need for agricultural producers in Africa to employ robust adaptive measures that withstand the risks of climate change. However, the success of adaptation measures to climate change primarily depends on the communities’ knowledge or awareness of climate change and its risks. Nonetheless, existing empirical research is still limited to illuminate farmers’ awareness of the climate change problem. This study employs a Bayesian hierarchical logistic model, estimated using Hamiltonian Monte Carlo (HMC) methods, to empirically determine drivers of smallholder farmers’ awareness of climate change and its risks to agriculture in Zambia. The results suggest that on average, 77% of farmers in Zambia are aware of climate change and its risks to agriculture. We find socio-demographics, climate change information sources, climate change adaptive factors, and climate change impact-related shocks as predictors of the expression of climate change awareness. We suggest that farmers should be given all the necessary information about climate change and its risks to agriculture. Most importantly, the drivers identified can assist policymakers to provide the effective extension and advisory services that would enhance the understanding of climate change among farmers in synergy with appropriate farm-level climate-smart agricultural practices.
23 pages, Increasing doctoral degree holders in Sub-Saharan Africa may significantly impact the quality and quantity of undergraduate and graduate programs. Research capacity is crucial to successfully completing a thesis or dissertation and obtaining a graduate degree. Unfortunately, in Sub-Saharan Africa, many students abandon or delay their degrees at this stage due to limited research and writing skills. This study aimed to identify the most critical thesis and dissertation (TD) research needs of masters and PhD students from Sub-Saharan Africa. Thirty-eight skills were identified from the literature and presented to agricultural education and extension/leadership students. Borich (1980) and Witkin (1984) needs assessment models were used to ascertain the perceived importance and extent of students' knowledge of TD topic areas. The top identified needs were extracting a manuscript from a thesis, writing a journal article, choosing inferential statistics, deciding the descriptive statics, and what to review in the literature. A total of 15 items were identified as critical needs using the Witkin model. The findings identified challenges and opportunities for improving Sub-Saharan African graduate students' research knowledge and TD performance, implying that combining the two models to identify training needs may produce more comprehensive results than using only one methodology.
12 pages., In sub-Saharan Africa (SSA), declining soil fertility is among the factors affecting optimal food production. Although a number of interventions have been implemented to improve soil fertility management (SFM) in SSA, their adoption especially among small scale farmers has been low. Although the literature provides considerable evidence of socio-economic factors which influence adoption, the subject of how communication influences adoption of SFM remains under-explored. This paper therefore reviewed studies on SFM communication in SSA. The objectives were to identify the current focus of studies on SFM communication, the current definitions of communication which informed such studies, and the type of SFM practices being communicated in the SSA region. Using specific search terms, articles were collected from various databases and content analysed. The review revealed five main themes as the focus of current studies on SFM. The study also revealed two main interpretations of communication which in turn influence the use of either diffusion or participatory communication strategies for SFM communication. The review also showed a focus on integrated soil fertility management (ISFM) messages in the SSA area. The study concludes that while each of the two communication strategies has their individual strengths, farmers prefer participatory strategies. This is because participatory strategies foster interaction and greater understanding; thereby, increasing the likelihood of farmer adoption of SFM practices in SSA. The review concludes by calling for further research on the use of participatory communication to engage farmers about various SFM practices in SSA.
22 pages, Commercialisation of smallholder agriculture is important for rural economic growth. While previous studies have analysed effects of commercialisation on productivity and income, implications for farm household nutrition have received much less attention. We evaluate the effects of commercialisation on household food security and dietary quality with a special focus on calorie and micronutrient consumption. We also examine transmission channels by looking at the role of income, gender, and possible substitution effects between the consumption of own-produced and purchased foods. The analysis uses survey data from farm households in Kenya and a control function approach. Generalised propensity scores are employed to estimate continuous treatment effects. Commercialisation significantly improves food security and dietary quality in terms of calorie, zinc and iron consumption. For vitamin A, effects are insignificant. Commercialisation contributes to higher incomes and increased nutrients from purchased foods, but it does not reduce the consumption of nutrients from own-produced foods. Enhancing market access is important not only for rural economic growth, but also for making smallholder agriculture more nutrition-sensitive.
15 pages., The aim of this research was to investigate the agricultural information sources and strategies for disseminating agricultural research findings to farmers in Iringa District, Tanzania. A total of 90 farmers were interviewed by using a self-administered questionnaire. The statistical Package for Service Solutions (SPSS) software and Spreadsheet were used as instruments to analyse the findings. Results of this study indicate that radios, church leaders, village leaders and seminars are the main channels of information used by extension officers to disseminate agricultural information to farmers. With regard to strategies the study revealed that, the use of religious leaders and government officials; use of primary school teachers and pupils; non-political interference; repackaging and packaging of technical information reports; deployment of extension officers in rural areas; use of community-based organisations and the establishment of agricultural information boards were the main effective strategies for disseminating agricultural research information to farmers. It is therefore, concluded that radio, church leaders, seminars, Newspapers, brochures and fliers should be intensively used to disseminate agricultural information among farmers so as to raise productivity in their farms. The study suggest that, there is a need to use other disseminators such as influential people, religious leaders, political leaders, primary school teachers and pupils to disseminate such information in addition to repackaging of agricultural research findings to tailor it to the farmers’ needs.
7 pages, Agricultural extension is the medium through which external agricultural technologies have been transferred to and transplanted in Africa to improve agricultural performance. Over a period of close to a century, different agricultural extension models have been proposed but their structure and content has virtually been the same: top-down, linear, non-participatory transfer of technology with no feedback loops for reverse diffusion. This presumably explains the poor performance of Africa’s agriculture and the scale of food security challenges facing the continent. In this review paper, we trace the history of agricultural extension and examine various agricultural extension delivery models to identify their major strengths and weaknesses, using Ghana and Burkina Faso as case studies. We then review the most recent literature in the field about the philosophy, scope, content, delivery, and outcomes of agricultural extension. The conclusion that agricultural extension has consistently remained out of sync with the needs and aspirations of stallholder farmers was reached. Smallholder farmers are now calling for new agricultural extension delivery models that are truly farmer-led, indigenous knowledge-based, context-specific, culturally-relevant and environmentally-sustainable to guarantee efficient farming systems into the future.

27pgs, In spite of mounting evidence about the growth of medium-scale farms (MSFs) across Africa, there is limited empirical evidence on their impact on neighbouring small-scale farms (SSFs). We examine the relationships between MSFs and SSFs, with particular focus on the specific mechanisms driving potential spillover effects. First, we develop a theoretical model explaining two propagating mechanisms: learning effects (training) and cost effects (reduced transactions cost). An empirical application to data from Nigeria shows that SSFs with training from MSFs tend to use higher levels of modern inputs (have higher productivity), and receive higher prices and income. The results also show that purchasing inputs from MSFs reduces the costs of accessing modern inputs and is associated with higher inorganic fertiliser use by SSFs. Our results suggest that the benefits of receiving training and purchasing inputs from MSFs are particularly important for very small-scale producers, operating less than 1 hectare of land. This implies that policies which promote the efficient operation of MSFs and encourage their interaction with SSFs can be an effective mechanism for improving the productivity and welfare of smallholder farms, hence reducing their vulnerability to extreme poverty.
