    Effect of agribusiness support services on choice of dairy cooperative market channel in Kenya
    Okello, D.; Owuor, G.; Larochelle, Catherine; Gathungu, E. (African Journals Online (AJOL), 2020)
    Kenya is witnessing an immense increase in number of smallholder dairy agripreneurs sourcing income from the dairy sub-sector. Smallholder dairy agripreneurs who dominate the production sector are forced to sell milk to informal buyers such as middlemen/women, who exploit them by paying less than the market price. As a result of this, the Kenyan Government has made significant efforts to upgrade dairy cooperatives to link the dairy agripreneurs with consumers. In spite of this, milk marketing is still dominated by traditional informal outlets. This study sought to determine the effect of provision of agribusiness support services on choice of dairy cooperative market channel. Data were collected from a cross-sectional survey of 682 respondents from Muranga County in Kenya, using a semi-structured questionnaire. Results revealed that provision of business plan training, group marketing, pregnancy diagnosis and deworming support services had significant and positive effects on the choice of cooperative market channel. In contrast, access to vaccination services and supply of feeds had negative effectson the choice of cooperative market channel. This study recommends strong coordination among the agribusiness support service providers and the dairy cooperatives in order to increase adoption of the cooperative marketing channel. In addition, dairy cooperatives need to redesign their business models to ensure that their members not only receive agribusiness support services, but also get better prices and prompt payments to increase supply of milk to cooperatives by dairy agripreneurs.

    Potential use of cover crops for soil and water conservation, nutrient management, and climate change adaptation across the tropics
    Delgado, Jorge A.; Barrera Mosquera, Victor H.; Alwang, Jeffrey R.; Villacis, Alexis H.; Cartagena Ayala, Yamil E.; Neer, Donna; Monar, Carlos; Escudero López, Luis O. (Elsevier, 2021-01-01)
    One of the greatest challenges in the 21st century is the question of how humanity will adapt to a changing climate to continue producing food at the production levels that will be necessary to feed an increasing global population while conserving soil and water resources. While there are political, social and economic factors that impact agricultural development, this paper will not be focusing on those factors, instead focusing on the potential use of cover crops as a nutrient management tool, a soil and water conservation practice, and a good approach to adapting to a changing climate. The potential of using cover crops for climate change adaptation and mitigation will be reviewed. Cover crops are a key tool that could contribute to increased yields, conservation of surface and groundwater quality, reduced erosion potential, sequestration of atmospheric carbon (C), and improved soil quality and health across the tropics. However, there are a lot of research gaps, and there is a need for additional research about the potential use of cover crops for soil, human, and animal health, as well as a need for an open-access data information system about research on cover crops in the tropics. While cover crops show a lot of promise, they are not a silver bullet, and in some circumstances, they can also contribute to reduced yields. We evaluated the use of cover crops and we ranked the different ways that cover crops can contribute to climate change adaptation, on a scale ranging from very low potential to contribute to climate change adaptation to very high potential. For example, cover crops have very high potential to reduce erosion generated by a changing climate in humid systems. On average, cover crops appear to be a good practice for climate change adaptation and mitigation across the tropics, and nutrient managers, agronomists, and soil and water conservation practitioners could add them to their management toolbox for different regions of the tropics. The 4 Rs of cover crops should be applied when using this tool (the right cover crop, the right timing of placement, the right timing of killing, and the right management).
