Water Engineers: A Pillar for National Water Security in Water-Stressed Regions

By | | , ,
Leave a comment

Water scarcity is now recognized as one of the most pressing global challenges of the 21st century. Climate change, population growth, urbanization, and industrial expansion have intensified pressure on already limited freshwater resources, particularly in water-stressed regions such as the Mediterranean and the Middle East and North Africa (MENA) [1,2]. According to UNESCO, more than two-thirds of the global population experience water scarcity for at least one month per year, with projections indicating further deterioration under current climate scenarios [1]. Within this context, the role of the water engineer has fundamentally evolved. Beyond the design and operation of treatment plants … Continue reading →

Can Atmospheric Water Generators Resolve Egypt’s Water Crisis?

Egypt faces an imminent water crisis which could jeopardize the country’s stability and regional dominance. Egypt is currently below the United Nations threshold of water poverty. The current water shortage in Egypt is 13.5 Billion Cubic Meters per year which is expected to continuously increase. According to hydrologists, a country is considered to be facing water scarcity if supplies drop below 1,000 cubic meters per person annually. Egyptian officials state there are currently around 570 cubic meters (150,000 gallons) of water available per person per year. This figure is expected to drop further to 500 cubic meters by 2025. The … Continue reading →

Pakistan’s Thirst for Water: Towards a National Sustainable Water Policy

By | | ,
1 Comment

Being the world’s 6th most populous country, Pakistan is home to about 210 million people. The growing population reduces average water availability every day. In 2017, Asian Development Bank reported that the agriculture sector of Pakistan consumes 93% of the water resources and contributes 21% – one-fourth – to the Gross Domestic Product. Pakistan Council of Research in Water Resources published a report titled “Water requirements of major crops in Central Punjab,” that has mentioned that over 60% of water is lost in transmission and applications. This implies that the agriculture sector that consumes 93% of water resources wastes two-third … Continue reading →

Water Diplomacy in the Middle East for Transboundary Water Supplies

By | | , ,
Leave a comment

Increased pressure on transboundary water supplies as a result of rising economic and population needs, exacerbated by climate change processes, can have catastrophic consequences in the Middle East. Management of groundwater extraction from transboundary aquifers must involve sharing the amount of accessible water and preserving its quality in order to ensure that future generations will have access to safe groundwater supplies. The Middle East is afflicted by internal water mismanagement and conflicts. This necessitates not only the building of water governance institutions but also diverse engagement platforms and other water diplomacy techniques. The negotiations about water management create the need … Continue reading →

Water Stress in the Mediterranean: Perspectives

By | | , ,

For many years now, the Mediterranean has been facing problems leading to a situation of serious environmental degradation. An increase in the temperature and salinity levels has been recorded during the second half of the 20th century in the Mediterranean Sea. However, this increase does not follow progressive trend and periods of temperature alternation have been observed. Following several climate change scientific reports, sea level trend at the global scale is higher than at the regional scales. Furthermore, in the regional scale there are other influence factors such the atmospheric pressure and the wind. In addition, the small rises in temperature … Continue reading →

The Promise of Seawater Desalination in Algeria: Perspectives

By | | , ,
Leave a comment

Algeria is one of the countries most exposed to water stress in the world. Classified as arid and semi-arid, it relies heavily on limited freshwater resources, with overexploited aquifers and dams often at critical levels during recurrent droughts. In response to this reality, the Algerian government has made seawater desalination a major strategic solution to secure potable water supply while alleviating pressure on natural freshwater resources. This approach goes beyond merely meeting human needs: it also potentially contributes to the preservation of terrestrial, marine, and freshwater ecosystems, in line with the objectives of the Kunming-Montreal Global Biodiversity Framework adopted in … Continue reading →

Water Security and Transboundary Conflicts: Geopolitical Challenges and Sustainable Water Governance

By | | ,
1 Comment

Water security has become a central determinant of geopolitical stability and sustainable development, particularly in arid and semi-arid regions. Increasing water demand, combined with climate change and fragmented governance of shared water resources, is intensifying tensions between states. This article analyzes transboundary water conflicts through several emblematic cases and highlights the critical role of cooperative governance, with a particular focus on the North Western Sahara Aquifer System (NWSAS). This study emphasizes that scientific transparency, institutional coordination, and regional cooperation are key to preventing water-related conflicts and ensuring long-term water security. Water as a Strategic Security Issue Water is no longer … Continue reading →

مستجمعات المياه الصحية أولوية حرجة لدفع التنمية المستدامة

تُعرّف مستجمعات المياه أو مساقط المياه (Watershed) بأنها مساحة من الأرض تُصرّف المياه الناشئة عن هطول الأمطار وانصهار الثلوج وتوجه تدفقها لتصب باتجاه الجداول والأنهار، وفي النهاية إلى نقاط التدفق (Outflow points) التي تصب في مستودعات المياه الأكبر حجما مثل الخلجان والمحيطات. ولكل جسم مائي مستجمع مياه أو أكثر. وتسمى أيضًا أحواض الأنهار أو أحواض التصريف (Drainage Basin). كما تُسمّى مصائد المياه (Catchment)، لأن الأرض الصاعدة والمرتفعة (Upstream) تصطاد المياه ومن ثم تجري إلى أسفل التل (Downstream) في اتجاه مجرى النهر أو الجدول القريب. تتكون المستجمعات المائية من وديان منحدرة تحيط بها قمم وتلال مرتفعة. ويتم تحديد حدود مستجمعات المياه … Continue reading →

World Water Day, celebrated every year on 22 March under the auspices of the United Nations, provides a unique opportunity to draw international attention to the vital importance of freshwater and to the persistent challenges related to its access, management, and sustainability. Since its inception, this observance has highlighted an annual theme addressing emerging priorities and structural challenges in the global water sector. In 2026, the chosen theme, “Water and Gender,” explicitly recognizes the close link between water management, sanitation, and gender inequalities, underscoring that the global water crisis is also a social, economic, and human crisis [1]. Although water … Continue reading →

Desalination as an Integrated Water–Energy–Material System in Water-Stressed Regions

By | | ,
Leave a comment

Water scarcity has become a structural constraint for sustainable development in arid and semi-arid regions. In North Africa, declining renewable water availability, recurrent droughts, population growth and agricultural demand have pushed conventional water resources beyond their renewal capacity. As a result, seawater desalination has evolved from an emergency response to a strategic infrastructure for national water security. However, the rapid expansion of desalination systems has revealed systemic challenges extending beyond water production. Energy consumption, membrane fouling, chemical use, brine discharge and environmental impacts increasingly determine the sustainability and social acceptability of desalination. At the same time, desalination brine—traditionally considered a … Continue reading →

Water, the most basic and essential resource on Earth, has become a privilege in many parts of the world. It is, without a doubt, one of, if not the most vital, resources for life. However, communities across the globe are increasingly facing drought and scarcity, and we have noticed a significant disparity in access to clean, drinkable water. As of 2022, nearly 500 million people across 19 African nations lack access to clean drinking water. The progress in resolving this issue has been slow due to the overexploitation of these resources, the impacts of climate change, and the historical sequels … Continue reading →
