The great cultural bloom that took place during the al-Andalus period was made possible from a material and social viewpoint thanks, among other factors, to the judicious water management at those times. Countryside, cities, public bathhouses and fountains, qanats, mosques and gardens honoured the element of water. However, this water culture emerged from a distinctively Islamic conception which is briefly summarized in the following paragraphs. Water in the Holy Quran In Islam, life and knowledge originated from water, a divine gift that symbolises profound wisdom, the drink that quenches the soul’s thirst. But it is also science. Thus, the word al-ma’a – … Continue reading →

Desalination at the Heart of Algeria’s Green Hydrogen Future: Water Security as a Strategic Energy Lever

By | | , ,
Leave a comment

Algeria stands today at the crossroads of two defining transitions: the global shift toward low-carbon energy systems and the intensifying pressure on water resources across arid and semi-arid regions. In this dual transformation, green hydrogen has emerged not only as an industrial opportunity but as a strategic lever capable of reshaping the country’s energy model, export structure, and environmental trajectory. Yet, at the heart of this hydrogen ambition lies a critical enabler that is too often underestimated: desalination. Green hydrogen, produced through water electrolysis powered by renewable electricity, is increasingly recognized as a cornerstone of global decarbonization strategies [1,2].

Water is an important vector in the socio-economic development and for supporting the ecosystem. In the arid to extremely arid Arabian Peninsula, home of the GCC countries, the importance and value of water is even more pronounced. The GCC countries of United Arab Emirates, Bahrain, Saudi Arabia, Oman, Qatar, and Kuwait, are facing the most severe water shortages in the world.  Rainfall scarcity and variability coupled with high evaporation rates have characterized this part of the world with a limited availability of renewable water. However, the scarcity of renewable water resources is not the only distinctive characteristic of the region, … Continue reading →

Zero Liquid Discharge and Brine Valorization in Seawater Desalination: Perspectives for the MENA Region

By | | , ,
Leave a comment

Abstract The expansion of seawater desalination has significantly increased global brine production, exceeding 140 million m³/day, with more than half generated in the Middle East and North Africa (MENA) region [1]. Brine disposal poses environmental and economic challenges, particularly in semi-enclosed marine systems. Zero Liquid Discharge (ZLD) and brine valorization strategies aim to eliminate liquid effluent while recovering water and valuable minerals. This study analyzes current ZLD configurations, mineral recovery pathways, and techno-economic constraints. Particular attention is given to the Saudi Arabian national strategy as a leading example of industrial-scale brine mining. The findings indicate that hybrid membrane–thermal systems combined … Continue reading →

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 →

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 →

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 →

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 →

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 →
