This book comprehensively discusses different scientific approaches, including groundwater sustainability, numerical modeling, index approach, isotope hydrology, environmental Isotopes, and advanced GRACE satellite data from different regions in developing countries globally, to help understand the groundwater system for strategic management of freshwater resources. This would help estimate an accepted logistic framework that might help control, and evaluate the significance of predicted climatic and anthropogenic impacts on groundwater resources. The book presents and discusses unique case studies from Asia (Turkey, Afghanistan, and Kyrgyzstan), MENA (Middle East and North Africa), particularly focussing on Algeria, Egypt New Delta, and KSA and West Africa (Nigeria) and has chapters covering most of the other MENA countries. The book presents a comprehensive investigation of the methods employed for groundwater utilization, with a dual focus on elucidating existing issues and confronting contemporary challenges. The findings are significant as they provide a deeper understanding of the complex issues surrounding groundwater utilization. Approaches for enhancing and rationalizing water extraction from Saharan aquifers are discussed to promote regional advancement and preserve long-term sustainability. The book will be of great help to numerous researchers and academicians, and will be an important account for stakeholders.
