Determinants for Use of Certified Maize Seed and the Relative Importance of Transaction Costs
The rising world prices for major tradable staples such as maize have been a concern for sub- Saharan countries such as Kenya which are maize deficit countries. Maize is a major staple food for over 80 percent of Kenya’s population. Kenya relies on maize for up to 40 percent of its dietary energy supply and is accordingly searching for ways to increase maize productivity. Maize productivity has been rising in the last decade manly as a result of the use of improved germplasm and fertilizer. However, the proportion of farmers using these technologies is low and the aggregate productivity in maize is low compared to other countries and its potential. Previous studies on input adoption have often assumed the existence of perfect supply and product markets, tending to ignore the important but significant role played by institutions as well as the role of transaction costs associated with market exchange. This study makes use of qualitative information from institutions and actors in seed input value chains as well as quantitative information collected from a sample of 150 farmers, in the Moist Transitional Maize Zones of Kenya. A two stage regression model was applied to analyze determinants of adoption and factors affecting degree of adoption of certified improved maize seed. The results show that as farmers adopt certified seeds, they incur higher transaction costs than non adopters, rural infrastructure, social capital such as membership in groups and trust play an important role in the decision of whether or not to use certified seed.Crop Production/Industries,
Technology Awareness and Adoption: The Case of Improved Pigeonpea Varieties in Kenya
We apply a program evaluation technique to data obtained from rural Kenya to assess the
patterns of adoption of improved pigeonpea varieties. The sample adoption rate of improved
pigeonpea is found to be 36% while potential adoption rate is estimated at 48%. The adoption
gap resulting from the incomplete exposure to the improved pigeonpea is 12%. Adoption is
prominent among farmers that close to the agricultural offices, and among younger and
wealthier farmers. The findings suggest that there is scope for increasing pigeonpea adoption
once the farmers are exposed to the new technologies and once the associated constraints are
addressed

MARKET SEGMENTATION STRATEGIES AND SEED PURCHASING DECISIONS AMONG SMALLHOLDERS: PRELIMINARY FINDINGS FROM KENYA
Efforts to increase agricultural productivity in sub-Saharan Africa require innovative approaches to improve smallholder access to new technologies. One increasingly popular approach is the use of market segmentation schemes to target smallholders with subsidized inputs. This paper presents results from an evaluation of the impact of a discount voucher scheme designed to encourage the purchase of improved maize seed by smallholders in two districts in Kenya. The study uses a randomized experiment to rigorously establish the counterfactual, i.e., ―what would have happened in the absence of the scheme?‖ Findings suggest that while the scheme generated a significant displacement effect, higher discounts on the price of seed did have a positive impact on seed purchases. The findings are relevant to government and corporate decision-makers interested in disseminating genetically modified crops to smallholders in sub-Saharan Africa through the use of discount vouchers tied to humanitarian use exemptions and royalty-free licenses

Consulting the stakeholders on pro-poor market segmentation of maize seed in Africa
Market segmentation, while popular in the pharmaceutical industry, is rarely used in agricultural technology dissemination, where beneficiary targeting is preferred. Market segmentation, while easy and cheap, tends to generate leakages, while beneficiary targeting, is typically associated with high administrative costs and distortionary effects.
To achieve a better understanding of the potential for using market segmentation to improve the adoption of agricultural technology, a consultation was organized in Kenya in May and June 2008 with stakeholders from the seed sector, NGOs, Ministry of Agriculture, agro-dealers and researchers. The consultation included individual visits to 9 stakeholders, a formal meeting with 39 stakeholders, and a formal questionnaire filled in by 18 respondents.
Results indicate that indirect identification of the poor is difficult, since poor and non-poor live in the same areas and use the same technologies.
The consultations show that several organizations in Kenya, including government agencies, non-governmental organizations, and seed companies, supply reduced-cost inputs to the poor, and they commonly use direct identification of the poor. The costs of such exercises seem to be high, but no data are available on costs or the accuracy of the identification. There seems is no experience with tiered pricing, although stakeholders generally find it interesting.
Most stakeholders showed an interest in experimenting with pro-poor market segmentation for maize seed. The two main market segmentation strategies that are viable are direct targeting, which is likely to be expensive but with limited leakage, and tiered pricing, which is likely to be a lot cheaper but with higher leakage, and which would need a control mechanism to avoid beneficiaries coming back for a second tier. To compare the costs and the benefits of both methods, as well as of different implementation options, a pilot study is needed. The main product of such a study should be maize seed at reduced prices (between 20% and 50%), up to a given quantity per farmer, provided at a discount (between 2 and 15 kg/household). The main tool would be cash vouchers, to be distributed by an independent agency based on direct identification of the target group, or the tiered pricing system, where each farmer receives vouchers for a specified amount. The agro-dealers will redeem their vouchers at an independent financial institution
A systematic review of Rift Valley fever epidemiology 1931-2014
Background: Rift Valley Fever (RVF) is a mosquito-borne viral zoonosis that was first isolated and characterized in 1931 in Kenya. RVF outbreaks have resulted in significant losses through human illness and deaths, high livestock abortions and deaths. This report provides an overview on epidemiology of RVF including ecology, molecular diversity spatiotemporal analysis, and predictive risk modeling. Methodology: Using the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines, we systematically searched for relevant RVF publications in repositories of the World Health Organization Library and Information Networks for Knowledge (WHOLIS), U.S Centers for Disease Control and Prevention (CDC), and Food and Agricultural Organization (FAO). Detailed searches were performed in Google Scholar, SpringerLink, and PubMed databases and included conference proceedings and books published from 1931 up to 31st January 2015. Results and discussion: A total of 84 studies were included in this review; majority (50%) reported on common human and animal risk factors that included consumption of animal products, contact with infected animals and residing in low altitude areas associated with favorable climatic and ecological conditions for vector emergence. A total of 14 (16%) of the publications described RVF progressive spatial and temporal distribution and the use of risk modeling for timely prediction of imminent outbreaks. Using distribution maps, we illustrated the gradual spread and geographical extent of disease; we also estimated the disease burden using aggregate human mortalities and cumulative outbreak periods for endemic regions. Conclusion: This review outlines common risk factors for RVF infections over wider geographical areas; it also emphasizes the role of spatial models in predicting RVF enzootics. It, therefore, explains RVF epidemiological status that may be used for design of targeted surveillance and control programs in endemic countries
Measuring consumer acceptance of instant fortified millet products using affective tests and auctions in Dakar, Senegal
Small-scale affordable extruders create new opportunities for small enterprise food processors to manufacture
nutritionally enhanced products. Still, consumer interest in these products needs to be assessed first. Affective
tests with 296 consumers in Dakar, Senegal, evaluated five pearl millet flours: (a) conventional, compared to
four instant-porridge flour products; (b) sifted; (c) wholegrain; (d) sifted with premix; (e) wholegrain with
micronutrient premix and food-to-food fortified (FtFF). Willingness-to-pay (WTP) was elicited through
experimental auctions under two treatments: firstly without information, then with information. Consumers
liked FtFF (taste, aroma, appearance) but were indifferent to instant. They did not appreciate wholegrain
flour (appearance) or premix (appearance, aroma and taste). Without information, consumers showed no
differences in WTP. With information, consumers paid premiums for FtFF (27-30%) (both treatments), and
premix (17%), instant (9%), and wholegrain (-10%) (one treatment). Costs of instant, wholegrain and premix
products were lower than consumers’ WTP, indicating potential profits, but not those of FtFF. There is a
market for instant cereals in Senegal. Consumers require product information in order to compromise on
some attributes to benefit from instant, fortified and wholegrain pearl millet products. Manufacture would
be cost-effective, but FtFF costs need to be reduced.http://www.wageningenacademic.com/loi/ifamram2022Consumer Scienc
Epidemiological Investigation of a Rift Valley Fever Outbreak in Humans and Livestock in Kenya, 2018
Comparison of knowledge, attitude, and practices of animal and human brucellosis between nomadic pastoralists and non-pastoralists in Kenya
Background The seroprevalence of brucellosis among nomadic pastoralists and their livestock in arid lands is reported to be over10-fold higher than non-pastoralists farmers and their livestock in Kenya. Here, we compared the seroprevalence of nomadic pastoralists and mixed farming with their knowledge of the disease and high-risk practices associated with brucellosis infection. Methods Across-sectional study was conducted in two counties - Kiambu County where farmers primarily practice smallholder livestock production and crop farming, and Marsabit County where farmers practice nomadic pastoral livestock production. Stratified random sampling was applied, in which sublocations were initially selected based on predominant livestock production system, before selecting households using randomly generated geographical coordinates. In each household, up to three persons aged 5 years and above were randomly selected, consented, and tested for Brucella spp IgG antibodies. A structured questionnaire was administered to the household head and selected individuals on disease knowledge and risky practices among the pastoralists and mixed farmers compared. Multivariable mixed effects logistic regression model was used to assess independent practices associated with human Brucella spp. IgG seropositivity. Results While the majority (74%) of pastoralist households had little to no formal education when compared to mixed (8%), over 70% of all households (pastoralists and mixed farmers) had heard of brucellosis and mentioned its clinical presentation in humans. However, fewer than 30% of all participants (pastoralists and mixed farmers) knew how brucellosis is transmitted between animals and humans or how its transmission can be prevented. Despite their comparable knowledge, significantly more seropositive pastoralists compared to mixed farmers engaged in risky practices including consuming unboiled milk (79.5% vs 1.7%, p < 0.001) and raw blood (28.3% vs 0.4%, p < 0.001), assisting in animal birth (43.0% vs 9.3%, p < 0.001), and handling raw hides (30.6% vs 5.5%, p < 0.001)., Conclusion Nomadic pastoralists are more likely to engage in risky practices that promote Brucella Infection, probably because of their occupation and culture, despite having significant knowledge of the disease
