Water management has become a critical global issue, evolving from a focus on scarcity to the pursuit of sustainability. As populations grow and climate change intensifies, the availability of clean water has emerged as a pressing challenge, threatening ecosystems, agriculture, and human health. Traditionally, water management centered on addressing immediate shortages through supply-side solutions such as reservoirs and water transfers. However, contemporary strategies emphasize a holistic approach that includes demand management, conservation, and the integration of advanced technologies. This shift reflects a broader understanding of the interconnectedness of water resources, the necessity for equitable access, and the imperative to protect this vital resource for future generations. Effective water management now aims not only to meet current needs but also to ensure long-term sustainability and resilience against environmental changes.
