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.

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.

MENA region is the most water scarce region in the world. The region is home to about 6.3% of world’s population, but has access to measly 1.4% of the world’s renewable freshwater. The region faces a dramatic increase in water demands due to rapid population growth, urbanization tendency, higher living standards, and an agricultural policy, which emphasizes expanding production in order to feed the growing population. Continued water scarcities will affect the social and economic potential of the region, increase the land vulnerability to salinization and desertification, and raise the risk of political conflicts around the limited water available and increasing demand. Groundwater is a hidden problem, since many countries extract more than it is being recharged. Water quality degradation through pollution and salinization are important factors affecting water availability in the region. In recent years, flash floods occurred by extreme weather events, their occurrence was highly random, and the associated problems are expected to increase in the near future due to climate change. Finding solutions to these challenging problems requires close collaboration between scientists – established as well as young ones - practitioners, and stakeholders from governmental and public organizations. The workshop will focus on multidisciplinary approaches to water challenges and their solutions with special interest on functions and limitations under various land-use systems and climatic conditions, remote sensing applications in water sciences, and latest technological developments for use and management of water in terms of sustainable water management.

Middle East and North Africa Region (MENA) is one of the water scarcest regions on earth. There, lack of water resources is common, and water scarcity has become an increasing constraint to their economic development, particularly of the agriculture, which is the biggest water consumer. Many countries in this region have been exploiting their non-renewable fossil water resources in order to relieve the acute pressure of water stress, depleting their resource base, and undermining their long-term economic development and food security, with additional consequences for human health and the environment. Disputes over water lead to tension within communities, and unreliable water services are prompting people to migrate in search for better living conditions. Water investments absorb large amounts of public funds, which could often be used more efficiently elsewhere. These challenges appear likely to escalate. Besides the availability of water, the efficiency of usage, e.g. in the agriculture, the suitability of plants cultivated, the yield values, etc. plays also an important role in decision making processes. As the region’s population continues to grow, water availability per capita is set to fall by 50% by 2050, and most of the countries in the region are going to face with “absolute water scarcity”. The expert workshop aimed at evaluating the options for coping with water scarcity through assessing the water demand and supply up to the year 2050, thereby considering issues like climate change, population growth, and economic development.

This book considers an array of state-of-the-art coupling and modelling concepts. First the relevant Earth system cycles are presented, followed by a discussion on scale issues and multiple equilibria. Inter- and intra-compartmental coupling is addressed, along with a debate on non-linearities and questions of parameterisation. Several applications are presented, where a focus is on cases where the hydrological cycle plays a central role.
