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 →

Advancing Circular Economy in Water Management in Algeria: From Wastewater to Strategic Resource

As climate change accelerates water scarcity across the Mediterranean and the Sahara, countries are compelled to rethink their approach to water management. The traditional linear model of extracting freshwater, using it once, and discharging it into the environment is no longer viable in regions where rainfall is decreasing, aquifers are overexploited, and agricultural demand continues to grow [1-2]. In Algeria, this challenge is especially acute – declining annual precipitation, high evapo-transpiration rates, rapid population growth, and urban expansion place tremendous pressure on limited freshwater resources. At the same time, industrial and agricultural demands continue to rise, further stressing conventional water … Continue reading →
