ABSTRACT
Effective water resource management is essential for regions like West Nusa Tenggara (NTB), where agriculture forms the backbone of the economy. This study examines the development of water infrastructure in NTB, focusing on its role in supporting key agricultural commodities. Using spatial analysis as an innovative approach, the study uncovers the relationship between water resource infrastructure, housing, settlements, and key commodities. This method offers insights into the distribution of clean water, infrastructure efficiency, and demand disparities, forming a foundation for more targeted water management strategies. The findings reveal a water surplus in NTB, accompanied by significant regional disparities. High-demand areas, such as Lombok Barat, Lombok Tengah, and Lombok Timur, face challenges due to population density and intensive agricultural activities, while regions like Sumbawa exhibit lower water demand. These results contribute to SDG 6 by identifying actionable strategies to improve water accessibility and promote sustainable agriculture. Key policy recommendations include modernising irrigation systems, fostering water-based industries, and integrating water resource management into regional development plans. By addressing these challenges with tailored solutions, the study supports sustainable agriculture in NTB and offers a replicable framework for optimising water infrastructure in similar regions, advancing broader goals of water and food security.
