Badung river basin sustainable water resources management for mitigate the effect of climate change.

Climate change has significantly affected global water resources, impacting their quantity and quality. Altered precipitation patterns, driven by climate change, have disrupted rainfall frequency, intensity, and distribution, directly influencing hydrology and water quality. Various economic sectors face challenges due to fluctuating rainfall patterns caused by climate change. The Badung Watershed, spanning Denpasar City and part of Badung Regency, plays a crucial role in supplying water to the region. It frequently experiences overflow during heavy rainfall. Understanding how climate change might affect rainfall patterns in this area is essential for mitigating potential consequences, although no prior research has explored this topic. Recent data shows a 67.93 millimeter decrease in average annual rainfall in the Badung Watershed, along with an annual temperature increase of 0.03 to 0.14 degrees Celsius, reduced relative humidity by 0.14%, and slower wind speeds by 0.02 meters per second. To address these challenges and ensure sustainable water resources, recommended strategies include water use planning and regulation, water conservation efforts, ongoing climate monitoring, and incorporating climate resilience planning in water usage practices. These measures are vital for the region's water resource management in the face of climate change. [ABSTRACT FROM AUTHOR]
