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 →

Leave a comment

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 →

زرع الأشجار لم يكن بهذه السهولة

ظاهرة الاحتباس الحراري  كانت كلمة جديدة بالنسبة لي عندما كنت في الصف السادس. مندهش من التأثيرات، سألت أستاذ العلوم، “إذا كان بإمكان طلاب مدرستنا زرع الأشجار؟”. كانت الفكرة هي زراعة حوالي 500 شجرة. لسوء الحظ، جاء الرد بالنفي. في الواقع، لقد كان تحديًا عمليًا بالنسبة لنا هو الحصول على المساحة لزرع والإبقاء على 500 شجرة، وكان ذلك نتاج افكاري وأنا طفل. في وقت لاحق، انتهى بنا المطاف في زراعة خمسة أشجار فقط، عاش منها اثنان. الآن عندما أزور مدرستي، وأنظر إلى الشجرتين اشعر بالفرح. وتعصف بذهني الافكار، ماذا لو زرعنا 500 شجرة وتمكنا من حماية أكبر عدد ممكن من ال … 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 →

Algeria stands at a critical energy crossroads. Long known as one of Africa’s leading producers and exporters of hydrocarbons, the country is now attempting to balance the twin imperatives of maintaining economic stability from oil and gas revenues while accelerating a shift to a cleaner, more diversified energy system. With global pressure to decarbonize mounting and domestic energy demand rising rapidly, Algeria’s energy transition is no longer just a vision, it is becoming a necessary strategic priority. But turning ambition into tangible results requires a careful blend of policy frameworks, incentives, partnerships, and effective implementation. Algeria’s renewable energy potential is … 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 →
