Seawater Reinvented: Inside the Race to Build Cleaner and Smarter Desalination

Desalination has stopped being an engineering footnote and quietly become one of the most consequential climate-era industries. Once synonymous with enormous power plants, thick plumes of hypersaline waste and prohibitive costs, modern desalination is remaking itself along three intertwined axes: slashing energy needs, turning brine from a waste into a resource, and folding data-driven intelligence into plants and networks. The result is a trajectory that could make seawater an affordable, environmentally acceptable pillar of water security for coastal and island nations ; provided the industry solves the brine and emissions puzzles fast enough. Recent projects and a surge of academic work … Continue reading →

Role of Algerian Matorrals in Biodiversity Conservation and Climate Adaptation

Matorrals, Mediterranean shrublands including maquis and garrigue form a key component of Algeria’s ecological landscapes. Stretching from coastal zones to foothills and lower mountain belts, they serve as transitional ecosystems between humid northern forests and southern semi-arid steppes. Despite their limited spatial coverage, they host rich biodiversity, including many endemic and xerophytic species, and provide crucial ecosystem services such as soil protection, carbon storage, and hydrological regulation. Their structural diversity and adaptive traits make them among the most resilient vegetation types under Mediterranean climatic stress. Recent national studies and international assessments (IUCN, Plan Bleu) highlight their essential role in land … Continue reading →

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

By | | ,

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 →
