| Abstract | Sanitation technologies are essential for human survival, health and prosperity, but they are potentially vulnerable to climate extremes. The main objectives of this study were: to verify the exposure of study areas to drought/flood; to assess the vulnerability of sanitation technologies (households‘ latrine) due to climate extremes, and to assess the adaptive capacity of rural community to sanitation failures due to climate extremes. To achieve these three objectives, rainfall data in study areas ---Jiangjin and Kaixian were collected from bureau of meteorology, to evaluate the exposure to drought/flood. For data source of vulnerability and adaptive capacity, questionnaire, interview to key informants and latrine improvement expert, field observation and literature review were conducted. For evaluation of vulnerability and adaptive capacity, both weighting and scoring methods were utilized. The main conclusions of this research were: first, the exposure of Jiangjin/Kaixian to drought/floods respectively was obviously high. Second, pit latrine under drought condition was assessed to occupy low vulnerability and to occupy high vulnerability under flood condition; 3-chamber septic tank latrine and biogas latrine were assessed to have moderate vulnerability under both drought and flood condition; Flush latrine was evaluated to have moderate vulnerability under drought condition. Overall, same technology under flood condition tended to be more vulnerable than under drought condition. Third, adaptive capacity of rural communities in Jiangjin was evaluated to be moderate and moderate~high for rural communities in Kaixian. |
