Adaptation and diffusion of biogas technology (Tanzania)

This study in Dar es Salaam examined biogas technology’s adaptation and diffusion using surveys, interviews, and laboratory analysis. The diverse sample included 100 community heads, 50 adopters, 50 non-adopters, and 16 key informants. Awareness of biogas varied, with 40% learning from neighbors, 6% from exhibitions, and a majority (54%) from seminars and expert sources. Key findings highlighted the significant role of community income levels, constituting 50.4% of factors influencing biogas adoption. Challenges included financial constraints reported by 75% and low attendance (64.05%) at critical training sessions. These findings underscored the need for targeted interventions to overcome barriers hindering widespread biogas technology adoption. The study also explored anaerobic digestion efficiency, emphasizing the impact of neutral pH levels on increased and enhanced biogas generation. Specific efficiency rates were detailed for various locations. In conclusion, the study revealed a current low level of biogas technology adoption in Dar es Salaam, emphasizing the essential role of government intervention in creating an enabling environment for technology advancement, uptake and adaptation
