Number and type of collapsed latrines.

In the context of monitoring progress towards SDG target 6.2, a household is counted to have access to sanitation if it uses at least basic sanitation services. Several approaches have been employed to help rural communities to climb up the sanitation ladder such as Community-led Total Sanitation (CLTS), whose primary target is to end open defecation through behavior change. CLTS does not subsidize sanitation facilities, but let households build their own facilities. The types and sustainability of facilities when construction is entrusted to households without guidelines remain understudied. The contribution of CLTS in achieving SDG6.2 also have not been studied. This paper addresses these gaps. Conducted in the province of Sissili in Burkina Faso, our study involved interviewing CLTS implementers, government officials, and community stakeholders. Coupled with household surveys, the data was analyzed using SPSS and Excel software. Findings indicate that CLTS succeeded in motivating households to build latrines hence escalating latrine coverage from 29.51% in 2016 (pre-CLTS) to 90.44% in 2020 (post-CLTS) in the province. However, 97.53% of latrines built were unimproved pit latrines with superstructures and without/with wooden or clay slabs and no roof, of which 19.76% collapsed during the rainy season. During this period, sanitation access rate rose from 11.9% to 17.00%. The study has therefore revealed that CLTS significantly elevates latrine coverage, yet it does not guarantee a proportional rise in sanitation access. This discrepancy results from the type of technologies generated by CLTS, which are not considered in calculating the sanitation access rate due to their unimproved nature. Consequently, further exploration of social approaches is essential, amalgamating technical and engineering aspects. Beyond socio-economic considerations, the sustainability of CLTS and the achievement of access to adequate and safe sanitation also rely on the robustness and resilience of the implemented facilities.在监测可持续发展目标6.2（SDG Target 6.2）推进进展的背景下，若家庭能够使用至少基础卫生服务，则认定该家庭拥有卫生设施可及性。已有多种举措助力农村社区提升卫生设施水平，其中以社区主导的全面卫生运动（Community-led Total Sanitation, CLTS）为代表，其核心目标是通过行为变革终结露天排便现象。CLTS并不为卫生设施提供补贴，而是由家庭自主建造设施。在无指导准则的情况下将建造工作委托给家庭时，所建设施的类型与可持续性仍未得到充分研究，CLTS对实现SDG Target 6.2的贡献也尚未被系统探究。 本研究旨在填补上述研究空白。本次研究在布基纳法索锡西里省开展，调研对象涵盖CLTS执行人员、政府官员及社区利益相关方，并辅以家庭问卷调查。研究收集的数据结合问卷结果，采用SPSS与Excel软件进行分析。结果显示，CLTS成功推动当地家庭建造厕所，使该省的厕所覆盖率从CLTS实施前的2016年的29.51%提升至实施后的2020年的90.44%。然而，所建造的厕所中97.53%为带有上层结构但无屋顶、仅配备（或未配备）木质或黏土盖板的非改良坑式厕所，其中19.76%在雨季发生坍塌。同期，该省的卫生设施可及率从11.9%升至17.00%。 因此，本研究表明，CLTS虽可显著提升厕所覆盖率，但无法确保卫生设施可及率实现同比例增长。这一差异源于CLTS催生的卫生技术类型：由于这些设施未达到改良标准，因此未被纳入卫生设施可及率的计算范畴。据此，有必要进一步探索融合技术与工程维度的社会干预路径。除社会经济因素外，CLTS的可持续性以及实现充足安全卫生设施可及性的目标，还取决于所建设施的坚固性与韧性。
