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.
9 pages., Cassava (Manihot esculenta) is an important regional food source, providing food and income to over 30 million farmers, processors, and traders in Nigeria. Extension programs support awareness and interest in new technologies; they facilitate the adoption and adaptation of new approaches to crop production, post-harvest processing, and marketing. Extension can be understood as an intermediary or catalyst in the dissemination of information to rural farmers. This study analyzed the effect of cassava farmers’ exposure to extension on a broad measure of cassava technology adoption, while considering the influence of some individual and farm characteristics as control variables. Data were obtained from personal interviews with sample of 952 households conducted in southern Nigeria. Results show a relationship between extension exposure and technology adoption. Farmer-to-farmer interaction played the greatest role in diffusion of the technologies. Interactions with extension agents were low, suggesting that adoption of improved technologies could be enhanced by improved regular contact with extension information. The results underscore the importance of farmer-to-farmer interaction processes that often overshadow extension assistance in supporting and guiding the use of production technology. The conclusions consider some implications for 21st century extension.
11 pages, Declining crop productivity is a great challenge facing smallholder farmers in Tanzania. Agro-ecological practices can improve crop productivity in a sustainable way and produce healthy food among smallholder farmers. Initiation of “Farmer-Led Research of Agro-Ecological Practices” (FLRAG) may enhance farmers’ capacities for innovation and co-develop suitable agro-ecological practices. This study aimed at identifying factors influencing smallholder farmers to participate in FLRAG. A cross-sectional survey was used to collect qualitative and quantitative data from 90 smallholder farmers in Mvomero, Bagamoyo and Masasi districts in Tanzania. Data were also collected from key informants who were extension officers. The study identified that experience in farming, easiness in accessing agro-ecological inputs, interest in doing experiments and farm size ownership are the factors that substantially influence smallholder farmers to participate in FLRAG. Therefore, researchers are advised to select participants of FLRAG by considering the mentioned factors. Furthermore, farmers selected to participate in FLRAG are advised to the use of ugunduzi app” that was developed purposefully to enhance agro-ecological research in order to test and understand its potential on smoothing agro-ecological research activities.
15 pages, In spite of several strategies implemented to improve sorghum production in Ghana, average grain yield in farmers’ fields remains low and far below the estimated potential. The development of effective strategies requires continuous, in-depth understanding of production constraints as well as farmer preferences for crop traits. To this end, a participatory rural appraisal using focus group discussions, interviews with semi-structured questionnaires and preference ranking was carried out among 122 smallholder sorghum farmers in the Upper East Region of Ghana. Majority (91%) of respondents were engaged in farming with more than half of their farm sizes allocated to sorghum cultivation. Drought, high cost of farm inputs and declining soil fertility were the top three constraints. Almost 42% of farmers described their soils as low in fertility. The most preferred traits by farmers were drought tolerance, high grain yield, earliness, grain quality as well as low fertilizer requirement. A better understanding of the perceptions of farmers and factors that limit the adoption of improved technology is important to guide policy towards the design of effective crop improvement and extension programmes. The study highlights the importance of breeding sorghum varieties with traits preferred by smallholder farmers that will lead to increased adoption of improved technology.
