    Adoption of Improved Mungbean Production Technologies in Selected East African Countries
    (Agriculture, 2021) Mmbando, Frank; Mbeyagala, Emmanuel; Binagwa, Papias; Karimi, Rael; Opie, Hellen; Ochieng, Justus; Mutuoki, Tarcisius; Nair, Ramakrishnan Madhavan
    This study analyzes the factors that influence the probability and extent of the adoption of mungbean production technologies in Tanzania, Kenya and Uganda, using multivariate probit and Poisson regression models. The results show that the probability and extent of the adoption of mungbean production technologies are influenced by gender of the household, household size, farm size, livestock size, household assets, access to extension services and access to credit. The study suggests that policy interventions that aimed at targeting women farmers, increasing household asset and information dissemination, such as field demonstrations and training programs, are crucial in enhancing technology adoption among smallholder farmers.

    Governance structures in smallholder pig value chains in Uganda: constraints and opportunities for upgrading
    (International Food and Agribusiness Management Review, 2017) Ouma, Emily; Ochieng, Justus; Dione, Michel; Pezo, Danilo
    This paper analyses governance structures in Uganda’s smallholder pig value chains by applying the New Institutional Economics framework. It utilises cross sectional and qualitative survey data from randomly selected pig value chain actors in 4 districts. A multinomial logit model is applied to assess the determinants of vertical integration among pig traders. The findings indicate that most relationships at the pig production node of the value chain are based on spot market governance structures supported by personal relationships and trust. Live pig traders are mostly vertically integrated. High integration levels of the pig traders are positively influenced by access to market information, value of investments in the value chain, and dedicated asset specificity in terms of backyard slaughter premises. Upgrading opportunities in the value chain in the form of value addition strategies, policy implementation and promotion of business models that link producer organisations to quality inputs and service suppliers through contractual arrangements are identified.

    Mungbean in Southeast Asia and East Africa: Varieties, Practices and Constraints.
    (Agriculture & Food Security, 2021) Sequeros, Teresa; Ochieng, Justus; Binagwa, Papias H.; Juma, Maurice Ogada; Kangile, Joseph Rajabu; Karimi, Rael; Mbeyagala, Emmanuel K.; Mvungi, Henry; Sanya, Losira Nasirumbi; Nguyen, Thi Tan Loc; Simfukwe, Esther; Suebpongsang, Pornsiri
    Improving the productivity of grain legumes is important to address global challenges of food security and soil degradation. This study’s objective was to quantify the adoption of improved mungbean (Vigna radiata L.) varieties and agricultural practices and to identify production constraints for six countries in Southeast Asia and three countries in East Africa. A Delphi method using expert elicitation was applied at subnational levels and then aggregated to national levels. Each panel employed repetitive and independent questioning of experts. The study organized 31 expert panels involving 387 experts across 9 countries. The share of improved varieties in the planted area, as estimated by the expert panels, was 92% for the Philippines, 91% for Vietnam, 99% for Thailand, 84% for Cambodia, 60% for Indonesia, 35% for Laos, 91% for Kenya, 30% for Uganda and 25% for Tanzania. The average age of improved varieties was 19 years in Asia and 12 years in East Africa. Of the mungbean area in Southeast Asia, 61% was planted to varieties developed by the World Vegetable Center, but this was only 2% in East Africa. Production constraints generally included insect pests and plant diseases, unstable markets with low price and low market demand, and the lack of quality seed of suitable varieties. There are ample opportunities to improve mungbean productivity through wider use of improved varieties and practices, which is important to meet the contemporary challenges of improving human nutrition and agricultural sustainability.
