12 pages, Conservation Agriculture (CA) has been widely promoted as a pathway to sustainably intensify agriculture in sub-Saharan Africa (SSA). Yet despite decades of promotion, CA uptake in SSA remains sparse with only few analyses of its impacts on farming and rural livelihoods. This study, which focuses on areas in Central Malawi considered to have a relatively high uptake of CA, uses analyses of satellite images, field observations, interviews with farmers, extension workers and other people involved in CA promotion, as well as a household survey, to investigate how CA has been adapted. We find that the three CA principles – (1) continuous minimum tillage, e.g. no-ridging, (2) permanent ground cover, and (3) crop rotation/intercropping – were not practiced as intended. First, one-third of non-ridged land was tilled during the growing season, and half was again ridged in the following season. Second, unless crop residues were added, the soil’s surface of non-ridged plots was usually bare at planting, causing weed control problems, and an increased risk of erosion. Most farmers added large volumes of crop residues to their non-ridged plots. They collected these from the surrounding fields, but this practice severely restricted the size of these plots. Third, crop rotation/intercropping was practiced less when farmers stopped ridging. Thus overall, very few farmers practised all of the three CA principles simultaneously. CA promotion appeared to only increase yields on plots where mulch was added, but this practice is not scalable. CA promotiondoes not seem to have provided substantial benefits for overall farm productivity, labour-savings or soil cons
14 pages., Edutainment, the combination of education with entertainment through various media such as television, radio, mobile phone applications and games, is increasingly being used as an approach to stimulate innovation and increase agricultural productivity amongst smallholder farmers in sub-Saharan Africa. Shamba Shape Up, a widely publicised makeover reality TV programme, is an example of edutainment that has received considerable attention, and airs in three countries in East Africa where it is estimated to be watched by millions of viewers.
There is no published academic research on the influence of makeover television formats on innovation systems and processes in smallholder agriculture. Using an Agricultural Innovation Systems approach, this paper explores how makeover edutainment is influencing smallholder farmer innovation systems together with the effect this is having on smallholder farms. In the absence of previous research, it articulates a Theory of Change which draws on research traditions from mass communication, agricultural extension and innovation systems.
Data came from two large scale quantitative (n = 9885 and n = 1572) surveys and in-depth participatory qualitative research comprising focus group discussions, participatory budgets, agricultural timelines, case studies and key information interviews in Kenya. An estimated 430,000 farmers in the study area were benefiting from their interaction with the programme through increased income and / or a range of related social benefits including food security, improving household health, diversification of livelihood choices, paying school fees for children and increasing their community standing / social capital.
Participatory research showed SSU enhanced an already rich communication environment and strengthened existing processes of innovation. It helped set the agenda for discussions within farming communities about opportunities for improving smallholder farms, while also giving specific ideas, information and knowledge, all in the context of featured farm families carefully selected so that a wide range of viewers would identify with them and their challenges.
Broadcasts motivated and inspired farmers to improve their own farms through a range of influences including entertainment, strong empathy with the featured host farm families, the way ideas emerged through interaction with credible experts, and importantly through stimulating widespread discussion and interaction amongst and between farmers and communities of experts on agricultural problems, solutions and opportunities. The fact that local extension workers also watched the programmes further enhanced the influence on local innovation systems.
The findings indicate that well designed makeover edutainment can strongly influence agricultural innovation processes and systems resulting in impact on the agricultural production and behaviours of large numbers of smallholder farmers.
6 pages, Despite the huge potential for milk production, interventions to improve productivity in sub-Saharan Africa (SSA) are barely based on specified farm classifications. This study aimed to develop robust and context-specific farm typologies to guide content of extension farm advice/services in Uganda. From a sample of 482 dairy farmers, we collected data on farmer socio-demographics, farm management practices, ownership of farm tools and facilities, willingness to pay for extension services, milk production, and marketing. Farm typologies were obtained based on principal component and cluster analyses. Thereby, of the three dairy production systems that emerged, small-scale, largely subsistence yet extensive and low productive farms were more prominent (82.6%). Farms that were classified as large-scale, less commercialized yet extensive with modest productive systems were more than the medium-scale commercial farms with intensive and highly productive systems. However, the later were considered to potentially transform dairy farming in Uganda. It was also predicted that the validity of our farm classification may persist until half of the farms have moved between clusters. The study gives new insights on dairy production systems in Uganda, which can be used to organize more targeted research on farmers’ extension needs for facilitating delivery of relevant and effective extension services and designing appropriate extension policies
21 pages, Despite decades of investment in agricultural extension, technology adoption among farmers and agricultural productivity growth in Sub-Saharan Africa remain slow. Among other shortcomings, extension systems often make recommendations that do not account for price risk or spatial heterogeneity in farmers' growing conditions. However, little is known about the effectiveness of extension approaches for nutrient management that consider these issues. We analyze the impact of farmers' access to site-specific nutrient management recommendations and to information on expected returns, provided through a digital decision support tool, for maize production. We implement a randomized controlled trial among smallholders in the maize belt of northern Nigeria. We use three waves of annual panel data to estimate immediate and longer term effects of two different extension treatments: site-specific recommendations with and without complementary information about variability in output prices and expected returns. We find that site-specific nutrient management recommendations improve fertilizer management practices and maize yields but do not necessarily increase fertilizer use. In addition, we find that recommendations that are accompanied by additional information about variability in expected returns induce larger fertilizer investments that persist beyond the first year. However, the magnitudes of these effects are small: we find only incremental increases in investments and net revenues over two treatment years.

17 pages., Via online journal., This article provides new estimates of the marginal product of public agricultural research and extension on state agricultural productivity for the U.S., using updated data and definitions, and forecasts of future agricultural productivity growth by state. The underlying rationale for a number of important decisions that underlie the data used in cost‐return estimates for public agricultural research and extension are presented. The parameters of the state productivity model are estimated from a panel of contiguous U.S. 48 states from 1970 to 2004. Public research and extension are shown to be substitutes rather than complements. The econometric model of state agricultural TFP predicts growth rates of TFP for two‐thirds of states that is less than the past trend rate. The results and data indicate a real social rate of return to public investments in agricultural research of 67% and to agricultural extension of 100+%. The article concludes with guidance for TFP analyses in other countries.
