Water scarcity is a pressing global issue exacerbated by factors such as population growth, urbanization, climate change, and inefficient water management. As the world faces this challenge, artificial intelligence (AI) emerges as a transformative solution for water conservation. AI, a field of computer science enabling machines to mimic human intelligence, offers tools to revolutionize water resource monitoring, allocation, and optimization. This chapter explores AI’s role in various domains like water management, precision agriculture, water quality monitoring, drought prediction, and early warning systems. It delves into the synergy of AI with Internet of Things (IoT) and data analytics, creating real-time decision-making in smart water systems. Ethical considerations and challenges are also discussed. Through case studies and real-world applications, this chapter highlights AI’s contributions to sustainable water management, emphasizing its crucial role in addressing the global water crisis.
