This study indicated that introduction of biogas digester for household use has both positive and negative influence to livelihood and forest management in Nepal. Biogas users showed less consumption of firewood, time for firewood collection, cooking time. In addition, biogas users consume more time for agricultural work, and they had more agricultural production and income from agricultural products than that of non-users. Moreover, biogas users assumed that they are more active for forest management because they have more accurate information about their own forest user group than non-users. However, these positive influences may enlarge the gaps between users and non-users in the same village or commune. Dissemination of the digester should have a mechanism or a system to prioritize poor households as target of support. In order to achieve maximum effects from the biogas digester, biogas introduction should be a part of integral approach of rural development or forest protection rather than a convenient device.

这项研究表明，家庭使用沼气池对尼泊尔的生计和森林管理既有积极影响，也有消极影响。沼气使用者表现出较少的木柴消耗、收集木柴的时间、烹饪时间。此外，沼气使用者在农业工作上消耗的时间更多，他们的农业生产和农产品收入比不使用沼气的人更多。此外，沼气用户认为他们在森林管理方面更积极，因为他们比非用户更准确地了解自己的森林用户群体。然而，这些积极的影响可能会扩大同一村庄或公社的使用者和非使用者之间的差距。推广沼气池应该有一种机制或制度，优先将贫困家庭作为支助对象。为了最大限度地发挥沼气池的作用，沼气的引入应该是农村发展或森林保护的一部分，而不是一种方便的装置。
