Assessment of the adaptive capacity to the climate change of rural fresh water and sanitation – A case study in Can Gio district

Abstract

This work aimed at calculating and assessing the adaptive capacity (AC) 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, survey, and professional adjustment methods, the AC index was considered and evaluated via two main indicator groups: infrastructures (6 indicators) and humans (13 indicators). Results show that Binh Khanh has the highest AC index, 57 points–medium high level, with strengths in infrastructure, especially in the human indicator group. The management of local government, transportation system, or social services are the highlights here. AC index in Can Thanh is runner-up with 55 points - medium high level. However, different from Binh Khanh, strengths in Can Thanh come from infrastructure group. AC indices of Ly Nhon, Tam Thon Hiep, Thanh An, Long Hoa, and An Thoi Dong are at medium low level, ranging from 43–49. By 2020, 2025, AC index increase following the increase in water supply and drainage network, social and economic development plan. This work also review strengths and weaknesses in CC adaptive capacity of RFWS in the local, supplying the basis for establishing solutions to mitigate CC impacts.
