The National Biodigester Program (NBP) was established in 2006 to build and maintain household biodigesters in Cambodia. In its first six years, the program installed almost 20,000 biodigesters and established an in-country network of local financiers, construction companies, skilled masons, bioslurry specialists and after-care technicians accessible to rural users in 14 of 24 Cambodian provinces. Since its initial success, the program's adoption rates have stalled despite increasing government support and high rates of user satisfaction. Building on an initial evaluation of the NBP in 2013, this updated assessment identifies multiple changes in its second implementation phase that have undermined the initial momentum of the program. Abrupt interruptions in institutional support, deteriorating supply side services (access to construction agents, masons, repair services) and reduced access to credit for farmers have eroded the service network that the first implementation phase established. Structural changes in the rural economy may also contribute to declining demand. Government support to another biodigester program which offers a lower investment price, but does not provide after-sales services has also undercut the long-term implementation strategy of the NBP. The paper finds that despite these programmatic changes, the installed biodigesters continue to perform according to expectation and to be maintained and valued by their users, but the future viability of the program remains uncertain.

柬埔寨国家生物消化器计划的评估

国家生物消化器计划 (NBP) 成立于 2006 年,旨在在柬埔寨建造和维护家庭生物消化器。在最初的六年里,该计划安装了近 20,000 台生物消化器,并在柬埔寨 24 个省中的 14 个省建立了一个由当地金融家、建筑公司、熟练泥瓦匠、生物泥浆专家和后期护理技术人员组成的国内网络,可供农村用户使用。自最初成功以来,尽管政府支持不断增加且用户满意度很高,但该计划的采用率一直停滞不前。在 2013 年对 NBP 的初步评估的基础上,此更新的评估确定了其第二个实施阶段的多项变化,这些变化破坏了该计划的初始势头。机构支持的突然中断,供应方服务的恶化(获得建筑代理、泥瓦匠、维修服务)和农民获得信贷的机会减少,侵蚀了第一实施阶段建立的服务网络。农村经济的结构性变化也可能导致需求下降。政府对另一个投资价格较低但不提供售后服务的生物消化器项目的支持也削弱了 NBP 的长期实施战略。该论文发现,尽管有这些程序上的变化,安装的生物消化器继续按预期运行,并得到用户的维护和重视,但该程序的未来可行性仍然不确定。维修服务)和农民获得信贷的机会减少侵蚀了第一实施阶段建立的服务网络。农村经济的结构性变化也可能导致需求下降。政府对另一个投资价格较低但不提供售后服务的生物消化器项目的支持也削弱了 NBP 的长期实施战略。该论文发现,尽管有这些程序上的变化,安装的生物消化器继续按预期运行,并得到用户的维护和重视,但该程序的未来可行性仍然不确定。维修服务)和农民获得信贷的机会减少侵蚀了第一实施阶段建立的服务网络。农村经济的结构性变化也可能导致需求下降。政府对另一个投资价格较低但不提供售后服务的生物消化器项目的支持也削弱了 NBP 的长期实施战略。该论文发现,尽管有这些程序上的变化,安装的生物消化器继续按预期运行,并得到用户的维护和重视,但该程序的未来可行性仍然不确定。但不提供售后服务也削弱了NBP的长期实施战略。该论文发现,尽管有这些程序上的变化,安装的生物消化器继续按预期运行,并得到用户的维护和重视,但该程序的未来可行性仍然不确定。但不提供售后服务也削弱了NBP的长期实施战略。该论文发现,尽管有这些程序上的变化,安装的生物消化器继续按预期运行,并得到用户的维护和重视,但该程序的未来可行性仍然不确定。
