The overall objective of the NDBMP was to further develop and disseminate domestic biogas in rural areas with the ultimate goal of establishing a sustainable and commercial biogas sector in Bangladesh. In line with the key expected results as identified in the original plan, the NDBMP needed to undertake a Users’ Survey at the field level from time to time in order to evaluate and monitor the performance and achievement of the key indicators of the program. The survey made a comprehensive assessment by:

• Measuring important direct and indirect benefits
• Assessing various impacts of biogas technology on energy, emission reduction and environment, health and sanitation, and the agriculture system
• Evaluating the technical soundness
• Identifying climate change, and the workload of women and children
• Measuring the socio-economic effects on the users
