The increasing pressure on water, energy, and food systems in arid and semi-arid regions has accelerated the search for integrated solutions capable of addressing these interconnected challenges. In the MENA region, where water scarcity is structural and climate change is intensifying hydrological variability, the convergence of renewable energy and agriculture has emerged as a strategic pathway toward sustainability. In particular, the coupling of renewable energy technologies with brackish water desalination offers a promising approach to support high-value crop production while minimizing environmental impacts and enhancing resource efficiency. This integrated paradigm aligns with the water–energy–food nexus framework, emphasizing synergies, co-benefits, and … Continue reading →

World Water Day 2026: Celebrate Water and its Richness for Humanity

By | | ,
Leave a comment

World Water Day is celebrated and recognised on the 22rd March each year. This year is no different. The United Nations chose to connect and celebrate World Water Day 2026 in the context of equality, namely gender equality with a focus on women. Let us manage water with equality. We appreciate that where there is water, plants grow, communities can grow, animals and humans can survive and prosper. But the question is whether there is equality where there is water. A great thought to ponder from many different perspectives. A simple yet critical question is multifaceted. Is there water? Is … Continue reading →

When Water Becomes a Strategic Weapon – Desalination Dependency, Geopolitics and Future of Water Security in the MENA

By | | ,
Leave a comment

Abstract Water scarcity is increasingly recognized as one of the most critical systemic risks of the 21st century. Nowhere is this challenge more evident than in the Middle East and North Africa (MENA), the most water-stressed region in the world. In response to structural freshwater scarcity, several Gulf countries have developed extensive desalination infrastructures that now supply the majority of their drinking water. While desalination has enabled rapid urban and economic development in extremely arid environments, it has also introduced new strategic vulnerabilities by linking water security to energy infrastructure, maritime transport routes and geopolitical stability. This article analyzes the … Continue reading →

Bottled Water vs Tap Water: Environmental, Economic and Health Implications

By | | , ,
Leave a comment

Abstract Global bottled water consumption has increased significantly over the last two decades, exceeding 350 billion liters annually. Bottled water is often perceived as safer and of higher quality than municipal tap water. However, recent scientific research challenges this perception. Studies have revealed the widespread presence of microplastics and nanoplastics in bottled water, while life-cycle analyses demonstrate that bottled water production generates substantially higher carbon emissions compared with tap water distribution systems. This study provides a comprehensive comparison of bottled water and tap water in terms of water quality, environmental impact, and economic cost. The analysis suggests that under properly … Continue reading →

Economics of Desalination and Local Integration: Comparative Analysis of CAPEX, OPEX, and Industrial Dynamics in Water-Scarce Regions

By | | , ,
Leave a comment

Seawater desalination has established itself as a cornerstone of water security in arid and semi-arid regions. Population growth, rapid urbanization, industrialization, and climate variability have significantly increased pressure on conventional water resources, making the use of non-conventional sources essential. Globally, installed desalination capacity has grown steadily over the past two decades, with tens of thousands of units in operation and daily production exceeding 100 million m³/day [1,2]. This expansion is particularly pronounced in the MENA region, which accounts for a majority of global capacity due to its structural water deficit.   Technological advances have profoundly changed the economics of the … Continue reading →

Water Management in the United Arab Emirates: Key Statistics

By | | , ,

The United Arab Emirates is among the top water-scarce countries in the world. However, the country has one of the world’s highest per capita water consumption of 550 liters per day. The country is experiencing a rapid increase in population which has in turn resulted in huge demand for water. In 2021, the total water consumption in UAE was 1754.5 million m3 (MCM) with the residential sector accounting for 981.4 MCM and the commercial sector 378.5 MCM. Water consumption in UAE is primarily divided among three sectors: Private households Agriculture Industries Household Sector This sector accounts for about 18% of … Continue reading →

Water Conservation in Islamic Teachings

Water occupies a pivotal role in Islam, and is recognized by Muslims as a blessing that “gives and sustains life, and purifies humankind and the earth”. The Arabic word for water, ma’a, is referenced exactly 63 times throughout the Holy Qur’an and is a recurring topic in many of the sayings of the Prophet Mohammed (peace be upon him). Water is not only praised for its life providing and sustaining properties, but it is essential in the daily life of a Muslim. A follower is required to complete ablution prior to the performance of the prayer, five times a day. … Continue reading →

Beyond Reverse Osmosis: How Hybrid MED+RO Systems and Green Energy are Securing Algeria’s Water Future

By | | ,
Leave a comment

Abstract Algeria’s pure reverse osmosis (RO) desalination systems face serious vulnerabilities: increasing turbidity events and frequent membrane replacements threaten operational stability, resulting in 1,680 hours of downtime annually across active plants. As the Mediterranean warms 20% faster than the global average, water security requires urgent innovation. This article proposes a hybrid MED+RO technology (1/3 thermal + 2/3 membrane) to ensure operational resilience. If RO shuts down, MED continues independently at 33% capacity, guaranteeing minimum supply. Although hybrid systems require a 28% higher capital investment, break-even is reached in year 16 due to reduced membrane replacement costs. Optimized pre-treatment with ultrafiltration … Continue reading →

Sustainable Management of Desalination Brine: Best Practices, Pilot Studies, and Innovations

By | | ,
Leave a comment

The management of brine generated by desalination plants has become one of the key determinants of the environmental and economic sustainability of this technology, which is now strategic for global water security. The production of desalinated water has increased significantly over the past two decades, particularly in arid regions of the Middle East, North Africa, Australia, and certain coastal areas of Europe and North America. This growth has inevitably been accompanied by a proportional increase in brine volumes. Globally, desalination facilities are estimated to produce more than 140 million cubic meters of brine per day, exceeding the volume of freshwater … Continue reading →

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].
