This paper analyses the Africa Biogas Partnership Program (ABPP) in Kenya, Tanzania and Uganda. ABPP was established in 2009 to promote adoption of biodigesters by rural households in sub-Saharan Africa. We use the RE-AIM framework (Reach, Effectiveness, Implementation, Adoption, Maintenance) with information from literature, internal documents, primary data from user surveys and interviews with sector stakeholders. ABPP was implemented with the primary objective of establishing viable biodigester markets. By 2017, Kenya made most progress toward commercial viability, evidenced by market entry of companies offering prefabricated digesters and establishment of 22 marketing hubs, which link rural organizations with local construction enterprises and finance institutions. In Uganda 5 marketing hubs were established and in Tanzania 7. Between 2009 and 2017 over 27,000 households installed a biodigester, half of them in Kenya. Additional objectives include improving agricultural productivity by using bioslurry, improving health, reducing deforestation, and improving livelihoods. Households perceive higher crop yields (84%-91% of users), reduced fuel consumption (84%-94% of users), reduced eye problems and respiratory symptoms (45%-91% of users). Benefits most appreciated are "easy cooking" and "saving time and money". Fuel consumption tests show households with biodigesters use 2.1 to 3.3 fewer tons of wood per year than similar households without biodigesters. The ABPP case study suggests that the program has created a nascent biodigester market in East Africa. The country programs have been dynamic and adaptive, moving along the cycle of market development; however, many challenges remain. For example, while half of the adopters in Kenya exclusively use biogas for cooking, in Uganda and Tanzania fuel stacking is more prevalent, making it more difficult to achieve health and environmental objectives. In addition, high upfront cost, limited access to credit, and lack of maintenance present challenges. In 2016, 27% of biodigesters constructed between 2009 and 2013 were not working. In response, ABPP implemented call centers and launched campaigns to repair non-functioning plants. To ensure long-term viability and increase the likelihood of achieving environmental and health goals, we suggest deeper engagement with governmental and non-governmental stakeholders and a targeted campaign promoting exclusive use.
本文分析了肯尼亚、坦桑尼亚和乌干达的非洲沼气伙伴计划(ABPP)。ABPP成立于2009年,旨在促进撒哈拉以南非洲农村家庭采用沼气池。我们使用RE-AIM框架(覆盖范围、有效性、实施、采用、维护),结合文献资料、内部文件、用户调查的原始数据以及对行业利益相关者的访谈。ABPP实施的主要目标是建立可行的沼气池市场。到2017年,肯尼亚在实现商业可行性方面取得了最大进展,提供预制沼气池的公司进入市场以及建立22个营销中心就是证明,这些营销中心将农村组织与当地建筑企业和金融机构联系起来。在乌干达建立了5个营销中心,在坦桑尼亚建立了7个。2009年至2017年间,超过27000个家庭安装了沼气池,其中一半在肯尼亚。其他目标包括通过使用沼液提高农业生产力、改善健康状况、减少森林砍伐以及改善生计。家庭认为作物产量提高了(84%-91%的用户),燃料消耗减少了(84%-94%的用户),眼部问题和呼吸道症状减少了(45%-91%的用户)。最受赞赏的好处是“烹饪方便”以及“节省时间和金钱”。燃料消耗测试表明,使用沼气池的家庭每年比没有沼气池的类似家庭少使用2.1至3.3吨木材。ABPP案例研究表明,该计划在东非创造了一个新兴的沼气池市场。各国的计划具有动态性和适应性,沿着市场发展的周期推进;然而,许多挑战依然存在。例如,虽然肯尼亚一半的采用者仅使用沼气做饭,但在乌干达和坦桑尼亚,燃料叠加更为普遍,这使得实现健康和环境目标更加困难。此外,前期成本高、信贷获取有限以及缺乏维护也带来了挑战。2016年,2009年至2013年间建造的沼气池中有27%无法正常使用。作为回应,ABPP设立了呼叫中心并发起活动来修复无法正常运行的设施。为确保长期可行性并增加实现环境和健康目标的可能性,我们建议与政府和非政府利益相关者进行更深入的合作,并开展一场促进独家使用的针对性活动。
