    Commercialization Pathways: Synegies Between Small And Medium Scale Farmers In Tanzania
    (2021-02) Alphonce, Roselyne; Muyanga, Milu; Minde, Isack
    The changing farm structures in sub-Saharan countries, with the emergence of medium and large scale farmers, has elicited opposing views in the literature. While much of this is largely positive, pointing to positive spillover effects in the larger agro-food industry, some studies point to some evidence of negative spill overs, especially due to land scarcity in the rural areas due to holding of land for speculation purposes, or higher food prices where large producers dedicate land to production for non-food crops. Nevertheless, evidence on the effects of these investments is scarce, with much of the evidence coming from case studies. This study investigates spillover effects of medium-scale farms and large scale farms on small scale farms productivity and commercialization in Tanzania. The study utilizes a sample of about 600 small scale farmers (less than 5 hectares of cultivated land) and about 600 large farmers, 300 medium scale (5 hectares to 10 hectares of cultivated land) and 300 large scale (greater than 10 hectares cultivated land) farmers drawn from eight district in rural Tanzania. A spatial econometric method is used to capture spillover effects from the large farms to small scale farms. Results show positive significant spatial dependence and spillover effects among medium scale and large scale farms on small scale maize productivity and commercialization, but not on rice, another major crop in the region.

    Consumer demand for branded and packaged processed foods: the case of rural and urban towns in Tanzania
    (Agricultural Economics Society of Tanzania, 2020-12) Kway, Yudathadei; Alphonce, Roselyne
    This paper elicit the demand for packaged and branded processed food products in selected urban and rural towns of Tanzania, where 630 consumers were randomly selected from two urban and four rural towns based on their size and distance from the primary city Dar es salaam. Garrett’s Ranking Technique and Multinomial Logistic Model were used to assess consumer’s purchasing habits and drivers of choices for branded and packaged processed foods. Results show that there are variations and some similarities in consumer habits in rural and urban towns, and in small and big towns on: - the type of processed foods bought, source of processed food, preference on brand types and drivers of consumer choices. The study shows that majority of the consumers in urban towns are driven by “quantity” while the rural consumers are driven by “storage” when buying packaged maize flour; on the other hand, “large volume” drives urban consumers, and “safety” rural consumers when buying packaged edible oil. In addition, the study showed that consumers from both rural and urban towns prefer branded to unbranded products due to their preference for “good sensory attributes”. Furthermore, results from the Multinomial Logistic Model report education, income, level of refinement and price to have a significant influence on the choice of a brand type for edible oil; while household size, trust, safety and nutrition are important factors influencing the choice of a brand type for maize flour. Implying choice of brand is different for different products, depending on the proliferation of these brands.

    Ex-Ante analysis of adoption of introduced chicken strains among smallholder farmers in selected areas of Tanzania
    (Springer Nature Switzerland AG, 2019-04) Andrew, Rogers; Makindara, Jeremia; Mbaga, Said H; Alphonce, Roselyne;
    Keeping local chickens is an integral part of Tanzania’s rural economy although it suffers low genetic potential. To address the problem, the Africa Chicken Genetic Gains (ACGG) project introduced and tested improved strains of chicken viz. Sasso and Kuroiler in Tanzania, The paper aimed to predict the rate of adoption of Sasso and Kuroiler chicken strains by using the Adoption and Diffusion Outcome Prediction Tool (ADOPT). Developmental research design involving provision of 25 six weeks old chicks to farmers was adopted. Data were obtained from a questionnaire survey and Focus Group Discussion in three regions of Tanzania. The results indicate that the peak for adoption is likely to be 34, 29 and 38% after 8, 7 and 9 years in Bahi, Ifakara and Wanging’ombe sites respectively. The sensitivity report indicates that the adoption rate may increase to reach 59, 49 and 57% and may decline to about 17, 16 and 21% in Bahi, Ifakara and Wanging’ombe respectively. Extension efforts to facilitate availability of the strains, feeds, treatment and reducing upfront and operating costs are main factors affecting change in the adoption rate to optimize the inherent genetic potential. It is recommended to facilitate extension efforts for adoption rate improvement by upgrading local chicken value chain to enable farmers to access the strains, feeds, medication and market.
