The ongoing Toilet Revolution in China offers an opportunity to improve sanitation in rural areas by introducing new approaches, such as urine source separation, that can contribute to achieving SDG6. However, few studies have systematically assessed the social acceptability of managing human excreta collected in new sanitation systems. Therefore, in this study we performed face-to-face interviews with 414 local residents from 13 villages across three provinces in western China, to analyze the current situation and attitudes to possible changes in the rural sanitation service chain. We found that the sanitation chain was predominantly pit latrine-based, with 86.2% of households surveyed collecting their excreta in a simple pit, 82% manually emptying their pits, and 80.2% reusing excreta in agriculture without adequate pre-treatment. A majority (72%) of the households had a generally positive attitude to production of human excreta-derived fertilizer, but only 24% agreed that urine and feces should be collected separately. Multivariate logistic regression indicated that three factors (level of education, number of permanent household residents, perceived social acceptability) significantly influenced respondents' attitudes to reuse of excreta, although only perceived social acceptability had a high strength of association. Overall, our survey revealed that rural households often misuse toilet systems, fail to comply with government-specified sanitation guidelines, have low awareness of alternative solutions, and are over-reliant on the government to fix problems in the service chain. Thus while new sanitation technologies should be developed and implemented, information campaigns that encourage rural households to manage their excreta safely are also important.
中国正在进行的厕所革命为通过引入新方法改善农村地区的卫生条件提供了机会,例如尿液源分离,这有助于实现可持续发展目标 6。然而,很少有研究系统评估管理新卫生系统中收集的人类排泄物的社会可接受性。因此,在这项研究中,我们对中国西部三个省份的 13 个村庄的 414 名当地居民进行了面对面访谈,以分析农村卫生服务链的现状和对可能发生的变化的态度。我们发现,卫生链主要以坑式厕所为基础,接受调查的家庭中有 86.2%的家庭使用简单的坑收集粪便,82%的家庭手动清空坑,80.2%的家庭在没有适当预处理的情况下将粪便重新用于农业。大多数(72%)家庭对生产人类排泄物衍生肥料的态度普遍较为积极,但只有 24%的家庭同意尿液和粪便应分开收集。多变量逻辑回归表明,有三个因素(教育程度、常住家庭人口数、感知的社会可接受性)显著影响了受访者对粪便再利用的态度,尽管只有感知的社会可接受性具有较高的关联强度。总体而言,我们的调查显示,农村家庭经常错误使用厕所系统,不遵守政府规定的卫生准则,对替代解决方案的认识不足,过度依赖政府来解决服务链中的问题。因此,虽然应该开发和实施新的卫生技术,但鼓励农村家庭安全管理粪便的宣传活动也很重要。
