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 →

Can Treated Wastewater Help Algeria Overcome Water Scarcity?

By | | , ,
1 Comment

Water scarcity is among the most critical environmental and socio-economic challenges confronting Algeria. Located largely within arid and semi-arid climatic zones, the country experiences highly variable rainfall, frequent droughts, and limited renewable freshwater resources. Per capita renewable water availability in Algeria is estimated at around 404 m³/year, placing the country well below the internationally recognized water scarcity threshold of 1,000 m³/year [1]. Climate change projections indicate further reductions in precipitation, rising temperatures, and increased evapotranspiration, all of which are expected to intensify water stress in the coming decades [2]. In this context, the search for alternative and non-conventional water resources … Continue reading →

Long-Term Solutions to Address Water Scarcity in Jordan

By | | , ,
Leave a comment

Jordan, characterized by its arid desert climate, is among the most water-scarce countries in the world. The nation’s renewable water resources amount to less than 100 m³ per capita annually—far below the water scarcity threshold. Overexploitation of groundwater, climate change, and rapid population growth have triggered an acute water crisis, leading to soil degradation, desertification, rising water costs, economic constraints, biodiversity loss, and public health challenges. Jordan primarily relies on surface water from rivers, groundwater, rainwater harvesting, and treated wastewater for reuse, while planning seawater desalination at Aqaba. To address the escalating water shortage, a long-term strategy integrating cloud seeding, desalination, … Continue reading →

How Algal Blooms Affect The Environment

By | | , ,
1 Comment

Algal blooms are thick layers of small green plants that appear on the surface of lakes and other water bodies due to excess nutrients, especially phosphorus and nitrogen. This covering on the surface of lakes and other water bodies is known as eutrophication. The excess level of nutrients that algae depend on results from human activities that cause pollution, such as fertilizer, wastewater, manure, and sewage runoff. Eutrophication can also be a natural occurrence from moderate accumulation of organic matter, silt, nutrients, and sediments gradually from the watershed. Algae come in different colors ranging from green, red, yellow, and brown. … Continue reading →

Membrane Innovation: Transforming Water Security in Arid Regions

By | | , ,
Leave a comment

Membrane innovation has emerged today as one of the most decisive technological levers for arid countries facing water scarcity, degradation of natural resources, and the rapidly increasing water demand for drinking, agricultural, and industrial water. At the heart of this silent revolution, membranes, whether reverse osmosis, nanofiltration, ultrafiltration, forward osmosis, or emerging processes such as biomembranes and graphene-based membranes, have transformed the way dry nations produce, recycle, and secure their water supply. Far from being a simple technical tool, they have become a major geopolitical, economic, and environmental instrument. In the context of accelerated climate change, where extreme droughts are … Continue reading →

Addressing water scarcity, both natural and human-induced, in the Arab region is considered one of the major and most critical challenges facing the Arab countries. This challenge is expected to grow with time due to many pressing driving forces, including population growth, food demand, unsettled and politicized shared water resources, climate change, and many others, forcing more countries into more expensive water sources, such as desalination, to augment their limited freshwater supplies. The heavy financial, economic, environmental, as well as social costs and burden to be borne cannot be overemphasized. Furthermore, the water scarcity challenge in the Arab world is being … Continue reading →

Sahara Nature-Based Solutions: Algeria’s Ancestral Water Systems for Climate Resilience and Sustainability

Leave a comment

North Africa is entering a new climate era defined by chronic drought, accelerating warming, and unprecedented pressure on water systems that were never designed for this level of stress. Over the last decade, the region has experienced a succession of dry years, but recent analyses from the Copernicus Global Drought Observatory show that since late 2023 the drought signal in northern Africa has been both multi-annual and structurally deeper than past cycles, with pronounced precipitation deficits, rising evapotranspiration, and abnormal land-surface temperatures. These dynamics have led to measurable impacts on groundwater recharge, agricultural productivity, and reservoir inflows, creating a complex … Continue reading →
