    Effect of Information Flow Through Social Networks on Adoption of Cage Fish Farming Technologies in Uganda
    (East African Journal of Science, Technology and Innovation, 2023-12-14) John Livingstone Mutyaba; Margaret Wairimu Ngigi; Oscar Ayuya Ingasia
    The philosophy of interpersonal interaction plays a significant role in facilitating learning processes between actors sharing a social network. It is a platform where actors actively share knowledge, skills and ideas, which affect their behaviour. Thus upon that premise, this study was conducted to understand the nature of smallholder farmers' social networks and their effect on the adoption of cage fish farming in Uganda. A cross-sectional survey was carried out across fourteen districts that share the waters of Lake Victoria in Uganda. A total of 384 respondents were selected using multistage sampling techniques and after seeking each one’s consent. Semi-structured questionnaires were used to collect data from the respondents, which was entered into an Excel sheet and exported to STATA (version 15) for analysis. Inferential statistics and a double hurdle regression model were used in this study. The study results revealed that an increase in the experience and group membership of a cage fish farmer by one-unit change increased the probability of using social networks by 0.43 and 0.70 units, respectively. Additionally, a unit increase in extension visits and credit access decreased the probability of using social networks by 0.59 and 1.06 units, respectively. Therefore, the study recommends a paradigm shift in extension services received by smallholder farmers to embrace the use of social networks and replicate them in other agricultural sectors. Additionally, financial services should be improved among cage fish farmers to promote credit access, and the role of group membership in promoting intensive cage fish farming should be considered as well.

    Impact of Informal Networks Among Cage Fish Farmers on Catch Potential
    (African Journal of Rural Development, 2023-03-31) John Livingstone Mutyaba; Margaret W. Ngigi; Oscar A. Ingasia
    Access to agricultural information is a critical factor, particularly among smallholder farmers in Sub-Saharan Africa. Many smallholder farmers in this region struggle on their own to access formal extension services, which limits their production potential. To circumvent this, many smallholder farmers are relying on information they share with their peers. To evaluate the impact of these information sources used by smallholder cage farmers the study employed a propensity score matching technique to compare farmers’ groups relying on informal and formal sources. A comprehensive survey involved the selection of 384 respondents from thirteen distinct districts located near Lake Victoria in Uganda. The findings revealed that smallholder are cage fish farmers who rely on informal sources of information were sharing timely and relevant agricultural information with their peers about cage fish technologies. Additionally, the result from the estimated average treatment effect (ATT) revealed a difference of 4539.21622 Kilograms of fish annually over the control group and was statistically significant at t=2.32; p=0.006. In terms of fish harvested in kilograms annually for the treated group was 24627.7162, compared to 20088.5 for the untreated. Therefore, recognizing and integrating social networks into the existing policy interventions, can help in empowering smallholder farmers and facilitate sustainable agricultural development in Uganda’s agricultural sector.
