This edited volume Irrigation Systems and Applications will introduce the reader to new irrigation technology and its diverse applications in modern farming. This work is organized into two distinct sections on “Irrigation Systems” and “Irrigation Applications” each offering a unique view into the potential of smart farming practices. From the deployment of hybrid energy-powered systems for smallholder farmers to the revolutionary impact of advanced micro-irrigation techniques, this book presents the reader with the latest trends and innovations in sustainable agriculture. Explore the evolution of rice production in the face of climate change, the enhanced productivity achievable through hydroponics, and the application of geospatial techniques in agricultural resource management. Smallholder irrigation for climate mitigation and cacao performance improvement in rainforest tropics and the quest for maximizing rice farming yields while minimizing water usage to sustain a hungry planet are also presented in this volume. With a focus on practical solutions and forward-thinking approaches, this book takes you through the essential facets of irrigation, providing valuable insights for researchers, students, and professionals alike. The book will help you understand irrigation’s pivotal role in shaping the future of global agriculture. Irrigation Systems and Applications is not just a book; it is a gateway to a greener, more resilient tomorrow in agriculture.
