Irrigation Management is essential to meet the growing demands of food production, ensure environmental health, and support socio-economic development in a water-stressed world. The textbook Irrigation Water Management presents a comprehensive and structured approach to understanding the principles, practices, and innovations that define modern water resource use in agriculture.

Spanning 18 well-organized chapters, the book begins with foundational knowledge on global water challenges, soil properties, and soil–plant–water relationships. It then progresses into the practical dimensions of irrigation scheduling, system design, water efficiency evaluation, and measurement techniques. Special attention is given to managing problematic water, conserving moisture, improving rainfed lowlands, and preventing waterlogging and salinization.

The text moves beyond traditional approaches by incorporating participatory water management, virtual water concepts, and emerging technologies such as smart irrigation systems. Tailored water-use strategies for different crops, case studies, and real-world scenarios provide readers with applied knowledge for diverse agro-climatic zones.

Designed as a core resource for undergraduate agricultural science students, this book also serves educators, extension professionals, and practitioners aiming to implement climate-resilient, water-efficient irrigation systems. The integrated perspective, blending ecological responsibility with technical precision, supports the development of skilled professionals ready to meet global water management challenges.

With its clear explanations, practical insights, and forward-thinking focus, Irrigation Water Management equips future agricultural leaders to become stewards of water resources, helping secure food systems and sustainable livelihoods for generations to come
