TAILIEUCHUNG - Assessing climate change exposure of rural fresh water and sanitation – A case study in cangio district
By index method associated with professional adjustment, analytic hierarchy process (AHP), data collection, and GIS methods, the study aimed to assess climate change (CC) exposure (E) of rural fresh water and sanitation (RFWS) via 7 indicator groups (including temperature, precipitation, wind, saltwater intrusion -SI, drought, riverbank landslide, and inundation), a case study in Can Gio district (Ho Chi Minh city) in the period of 2015-2025. | Vietnam Journal of Science and Technology 56 (1) (2018) 71-80 DOI: ASSESSING CLIMATE CHANGE EXPOSURE OF RURAL FRESH WATER AND SANITATION – A CASE STUDY IN CANGIO DISTRICT Ngoc Tuan Le1, *, Xuan Hoang Tran2 1 University of Science – Vietnam National University Ho Chi Minh City, 227 Nguyen Van Cu Street, Ward 4, District 5, HCMC 2 Institute of Meteorology Hydrology Oceanology and Environment, 60 Nguyen Dinh Chieu street, Da Kao Ward, District 1, HCMC * Email: lntuan@ Received: 1 November 2016; Accepted for publication: 13 November 2017 Abstract. By index method associated with professional adjustment, analytic hierarchy process (AHP), data collection, and GIS methods, the study aimed to assess climate change (CC) exposure (E) of rural fresh water and sanitation (RFWS) via 7 indicator groups (including temperature, precipitation, wind, saltwater intrusion -SI, drought, riverbank landslide, and inundation), a case study in Can Gio district (Ho Chi Minh city) in the period of 2015-2025. Exposure indices to CC of RFWS in Can Gio district would be almost at medium-low levels (E = 33 – 53) and tend to increase gradually from the infield to riverside areas, from land to sea. The highest E distributed in Thanh An, Long Tau riverside, and Phu Loi island. Some locations, having low E index but located in residential areas with plenty of infrastructures, could be more vulnerable, such as Nha Be riverside (Binh Khanh), Dong Dinh outfall, Tac Suot wharf (in Mieu Nhi, Mieu Ba -Can Thanh town), and Soai Rap riverside (Ly Nhon), and thus need taking into concerns. Keywords: climate change, rural fresh water and sanitation, exposure index. Classification numbers: ; . 1. INTRODUCTION Climate change (CC) is a major challenge for humanity in the 21st century. The increase in risks of CC and disasters (such as inundation, saltwater intrusion, etc.) has led to the increase in vulnerability of livelihoods, living standard, etc., .
