| dc.description.abstract | Energy is a critical driver of national growth, with global demand escalating rapidly due to population growth, industrialization, and increased transportation needs. In Uganda, where fossil fuel prices are soaring, biogas technology has gained prominence at the household level, particularly in rural areas, offering an affordable and sustainable alternative for tasks like lighting and cooking. However, despite the introduction of biogas technology in the 1950s, its adoption has been limited in Uganda.
This study explores the challenges and reasons behind the low acceptance of biogas technology in Uganda, shedding light on factors leading to a high abandonment rate, particularly in regions such as Luwero and Mpigi districts. Findings reveal that approximately 79% of households in Luwero and 29% in Mpigi discontinued biogas use within 3.5 years, citing difficulties in sustaining livestock production, a key source of feedstock. Additionally, issues such as a shortage of family labor and the inability to repair malfunctioning biogas digesters contribute to the technology's discontinuation.
Recommendations from the research emphasize the need for improved farm management practices to sustain livestock production, considering quality standards and socio-cultural factors in biogas digester design. Notably, the study highlights that 48% of biogas plants in central Uganda fail within six years after construction, far below their estimated lifespan of 25 years. Causes of failure include the lack of alternative feedstock during cow manure scarcity, inappropriate operation and maintenance practices, and suboptimal digester operating conditions. To address these challenges, the study suggests diversifying feedstock options, promoting proper operation and maintenance practices, and optimizing digester operating conditions for enhanced biogas technology sustainability. | en_US |
