Influence of Biogas Digester by Animal Manure on Forest Management in Nepal

这项研究表明，引入家庭使用的沼气池对尼泊尔的生计和森林管理既有积极的影响，也有消极的影响。沼气使用者的木柴消耗量、收集木柴的时间、做饭的时间较少。此外，沼气用户消耗更多的时间用于农业工作，他们有更多的农业生产和农产品的收入比非用户。此外，沼气用户认为，他们更积极的森林管理，因为他们有更准确的信息，他们自己的森林用户组比非用户。然而，这些积极的影响可能会扩大同一村庄或社区中使用者和非使用者之间的差距。消化器的推广应建立一种机制或制度，将贫困家庭作为优先支助对象。为了实现沼气池的最大效果，沼气的引入应该是农村发展或森林保护的整体方法的一部分，而不是一个方便的装置。

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.
