Description:	Langat River Basin in Selangor state is an emerging mega urban region in Malaysia. In the recent decades, it has transformed from an industrial agricultural basin to an urbanized area. The objective of the study was to determine the impact of progressive basin oriented urbanization (land use/land cover change) on its groundwater resources and the potential of groundwater resources as an alternative water source for growing drinking and development needs following an Ecosystem Approach. Landsat TM satellite images of the years 1974, 1981, 1988, 1996, 2006 and 2016 were used to analyze the land use change in the basin over the period of 1974-2016 using GIS technology. Data collected from Jabatan Minerals dan Geosains (JMG), Selangor/Federal Territories and Lembaga Urus Air Selangor (LUAS) on abstraction, usage pattern and quality parameters were utilized to assess groundwater quantity and quality. Correlation and Regression were utilized to analyze groundwater quality data, Further, urbanization and water security status in the basin are discussed under the umbrella of UN Sustainable Development Goals. The land use analysis results showed an increase in developed area from 2.39 % in 1974 to 43.77% in 2016. Agriculture land and forest had reduced to 25.68% (by half) and 28.96% respectively, while water bodies remain more or less same at 1.59%. Groundwater usage in the basin has been fluctuating over the years. Increase in groundwater level and temperature, slight decrease in pH over years 2010-2014, and higher concentrations of conductivity, TDS, Na, Cl, Mn, Fe, and Coliform indicated that groundwater quality is affected by urbanization. Strong correlation between these variables pointed to common contamination sources associated with urbanization. Other analyzed parameters are within standards. Recommendations for sustainable conservation, utilization, and management strategies for land and water, especially groundwater resources to attain water security both in the basin and in Malaysia are suggested. Establishment of a Langat River Basin Sustainability Committee is highly recommended; a priority list for land and groundwater development and management is proposed. More studies on surface-groundwater interactions, heavy metal and organic compound contamination, salt water intrusion, groundwater level decline, land subsidence, and sustainable extraction technologies are suggested in the region.,Certification of Master's/Doctoral Thesis' is not available,Master of Science
