The 2022 ROPME Policy Brief addresses the impacts of climate change on desalination plants and industrial cooling water systems in the ROPME Sea Area, which includes eight member states. It highlights the region’s critical dependence on desalination, with over 1,400 plants producing more than 25 million cubic meters per day, expected to rise significantly by 2050.
The brief identifies major climate risks, including rising sea temperatures and salinity, harmful algal blooms, jellyfish outbreaks, coastal erosion, and extreme weather events. These factors reduce operational efficiency, damage infrastructure, and disrupt water intake systems. Reverse osmosis plants are particularly vulnerable to water quality changes and biological fouling.
It emphasizes that the Inner ROPME Sea Area is most exposed to temperature and salinity increases, while the Middle and Outer areas are more affected by algal and jellyfish blooms. Climate projections indicate notable increases in sea temperature and salinity by the 2040s, compounded by desalination discharges.
To address these risks, the brief proposes adaptation measures at plant, national, and regional levels. These include improving intake design and location, upgrading filtration and membrane systems, developing early warning systems for algal and jellyfish blooms, and requiring climate risk assessments. Strengthening resilience through coordinated regional action is essential to ensure sustainable water and energy security in the face of climate change.
