Groundwater is the world’s largest source of fresh water, but its safe and sustainable exploitation remains a challenge. Egypt's Nile Valley aquifer is the most important renewable aquifer, accounting for approximately 85% of total groundwater use in Egypt. Egypt's long-term development and socioeconomic growth in the Nile Valley depends on this groundwater. Concerns about groundwater assessment, quality, management, and sustainability frame the current status of Nile Valley groundwater supplies. Proper knowledge of the current state of the groundwater quantity and quality in the Nile Valley is vital for the development and management of groundwater resources in Egypt. Due to Egypt's water scarcity, the projected decline in Nile River flow due to climate change, and the development of numerous Nile River basin projects, the situation is critical, and the consequences might be severe. Furthermore, Egypt's growing population puts significant strain on groundwater, which is the second most significant freshwater supply next to the surface water supply coming from the Nile River as Egypt’s share. Several books on the various aspects of Egypt's water resources have been published, but there is insufficient recent information on groundwater in the Nile Valley aquifer, which is essential for Egyptian populations for domestic and irrigation purposes. As a result, this book on the groundwater in the Nile Valley aquifer emerges to complete the picture of Egypt’s water resources as a good example of arid country located in MENA regions with many arid countries. Consequently, the lessons learned from this book could be beneficial to other countries in MENA regions, particularly those in North Africa.

This volume presents up-to-date research on the Nile Delta and discusses the challenges involved in and opportunities for improving its productivity. The topics addressed include: groundwater in the Nile Delta and its quality; the mapping of groundwater with remote sensing technologies; land degradation; salt-affected soils; on-farm irrigation; the remediation of agricultural drainage water for sustainable reuse; the use of satellite images to estimate the bathymetry of coastal lakes; the assessment of the Nile Delta coastal zone and its management; its sediment and water quality; and fishing ports, fish and fisheries. The book closes with a review of the latest findings on the Nile Delta and offers conclusions and recommendations for future research to fulfill the requirements for sustainable development. It provides a unique and topical resource for researchers, graduate students and policymakers alike.

Climate change is likely to continue to have severe impacts, including sea level rise. At the same time, population increase and development imperatives create additional pressure on available water resources. These changes are problematic for the Mediterranean coastal areas and especially the Nile Delta coast. Particular focus of this study is on salinization of groundwater resources in the Nile Delta Aquifer (NDA) due to saltwater intrusion. To assess current conditions and develop future adaptation strategies for the NDA, a 3D model simulating regional variable-density groundwater flow and coupled salt transport was constructed based on available data set, using the SEAWAT code. A method for identification of the most representative model has been developed, based on testing different simulation periods during which the NDA has ‘evolved’ from completely fresh groundwater conditions to conditions representative for the year 2010.This model was then applied to analyze possible future NDA conditions under several predefined scenarios of sea level rise and groundwater extraction. This analysis indicated that the impacts from further extractions of groundwater on availability of fresh groundwater in the aquifer are more significant compared to those from sea level rise. Furthermore, three different adaptation measures and their impacts in the Sharkeya Nile Delta governorate were tested. It was shown that that changing crop types and irrigation practices towards water saving options seem to be more promising than artificial recharge with injection wells or extraction and usage of brackish groundwater after desalination. The developed model is useful for further Water-Food Nexus studies.

This book brings together contributions from groundwater researchers and scientists on underground water resources in Egypt's deserts. The aquifers' quantity and quality are evaluated in many regions of the Egyptian deserts using established methods that can be effectively employed to investigate the potential for sustainable development in Egypt and similarly arid countries. The water resources in Egypt's deserts are subject to deterioration, mainly by land salinization and water deficiency. This book presents the best management practices, water quantity and quality, and optimal and sustainable usage of available groundwater. The book offers a unique guide for all readers interested in groundwater, modeling, and assessment for sustainable development in Egypt and countries with similar weather and water conditions.

The Nile provides freshwater not only for domestic and industrial use, but also for irrigated agriculture, hydropower dams and the vast fisheries resource of the lakes of Central Africa. The Nile River Basin covers the whole Nile Basin and is based on the results of three major research projects supported by the Challenge Program on Water and Food (CPWF). It provides unique and up-to-date insights on agriculture, water resources, governance, poverty, productivity, upstream-downstream linkages, innovations, future plans and their implications. Specifically, the book elaborates the history and the major current and future challenges and opportunities of the Nile river basin. It analyzes the basin characteristics using statistical data and modern tools such as remote sensing and geographic information systems. Population distribution, poverty and vulnerability linked to production system and water access are assessed at the international basin scale, and the hydrology of the region is also analysed. This text provides in-depth scientific model adaptation results for hydrology, sediments, benefit sharing, and payment for environmental services based on detailed scientific and experimental work of the Blue Nile Basin. Production systems as they relate to crops, livestock, fisheries and wetlands are analyzed for the whole Blue and White Nile basin including their constraints. Policy, institutional and technological interventions that increase productivity of agriculture and use of water are also assessed. Water demand modeling, scenario analysis, and tradeoffs that inform future plans and opportunities are included to provide a unique, comprehensive coverage of the subject.

The Nile Basin Initiative (NBI) is a remarkable achievement towards the cooperative management of the common Nile water resources. Based on a Shared Vision Program and a Subsidiary Action Program, the NBI has numerous ongoing projects on the ground. Research on the Nile water resources has been recognized to be crucial for successful implementation of the NBI projects. Therefore, IWMI and other research centers have worked together with the NBI to identify knowledge gaps pertinent to the Nile water resources. This report presents prioritized research questions, pertinent ongoing research projects and the implementing institutions; and available databases on the Nile.
