Assessmentof the sensitivity of rural fresh water and sanitation to the climate change – a case study in Can Gio district

Abstract

This work aimed at calculating and assessing sensitivity (S) to the climate change (CC) of the rural fresh water and sanitation (RFWS), a case study in Can Gio for the period of 2014 – 2025, by index (via 12 indicators), survey, and professional adjustment methods. Results showed that, in 2014, the S index of the whole district was 40.7 (medium low level), ranging from 29–58 among 7 communes (according to medium low to medium high levels). Binh Khanh had the highest S index, 58 points (2014), followed by An Thoi Dong, Tam Thon Hiep, and Long Hoa. For the period of 2020–2030, S indices of the district tend to decrease (35.3 and 33.9, respectively), ranging from low to medium low levels among the communes. This work also reviewed strengths and weaknesses in the sensitivity to CC of RFWS in the local, pointing out and prioritizing 7 defected links as the basis for establishing solutions to mitigate the S to CC of the system, serving the sustainable development objectives of the local.
