    Determinants of adopting Imazapyr-resistant maize technologies and its Impact of household Income in Western Kenya
    (AgBioForum,, 2011-01) Mignouna, D.B.; Manyong, V.M.; Rusike, J.; Mutabazi, K.D.S; Senkondo, E.M.
    This study identifies the adoption determinants and causal impact of adoption of imazapyr-resistant maize (IRM) on income and poverty among maize farming households using a logistic model and Heckman selection-correction model. Results from a randomly selected sample of 600 households consisting of 169 adopters and 431 non-adopters reveal that combined specific household, farm, institutional, and technological factors influ- ence the probability of adoption of the technology. The results also showed that adoption of IRM raises farm household income even after controlling for observable and unobservable house- hold characteristics. Conclusions drawn from this study are that the use of IRM for Striga control is a reasonable policy instru- ment to raise small-farm income and reduce poverty among maize farming households.

    Potential, challenges and opportunities for promoting integrated agri-aquaculture among vegetable growers and fish farmers in Mvomero district of Morogoro region, Tanzania
    (2021) Respikius, M; Ahmad, A.K; Lamtane, H; Mtui, H.D.
    Integrated Agri-Aquaculture (IAA) is the integration of fish farming within a broader farming system. Although this system is common in Asia, it is not widely practised in Africa and Tanzania in particular. For many years, lakes, ocean and rivers have been the main source of fish supply in the country. However, the recent upsurge in fish demand coupled with such factors as the use of destructive fishing gears, population growth and poor agricultural practices which lead to pollution and climate change have rendered these sources unsustainable. To increase fish supply, several interventions for promoting fish farming have been implemented. Specifically, IAA is promoted to optimally utilize locally available resources and reduce environmental impacts. However, the main concern is that there has been low yield attained from the IAA contrary to its aim of increasing overall farm yield and income. As a relatively new farming system in the target community, it deemed necessary to explore issues and conditions limiting IAA practice starting with testing its acceptability within the farming communities. The present study analysed the potentials, challenges and opportunities for adopting IAA in Mvomero district of Morogoro region, Tanzania. Both quantitative and qualitative data were collected from vegetable growers and fish farmers. Findings showed that there was a high level of awareness and interest in IAA among vegetable growers and fish farmers. However, only 14% of vegetable growers practised IAA compared to 75% of fish farmers. Lack of knowledge and quality inputs were the main challenges facing the IAA farming system. The study recommends practical training of vegetable farmers on IAA and Integrated Pest Management aspects as a means of promoting IAA. Efforts for IAA promotion should be geared towards facilitating the formation of farmer groups for peer learning and practising IAA
