US-Iran pause is a relief for Gulf desalination plants, water supply, Pg14

Key Highlights:

• US President postponed strikes on Iran's energy infrastructure for five days following conversations with Iran.
• The Gulf region's water desalination infrastructure was threatened by Iran as retaliation for potential US strikes.
• GCC countries rely on desalination plants to meet water requirements due to low rainfall and limited groundwater.
• In 2018, GCC nations had 172 water desalination stations with a combined capacity of 22 billion litres per day.

Detailed Insights:

• Desalination plants convert saltwater into drinkable water using membrane-based methods like reverse osmosis (RO) or heat-based methods.
• GCC countries, including Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the UAE, face water scarcity due to low rainfall (4-30 cm annually) and lack of rivers.
• Dependence on desalination plants is high due to limited replenishable groundwater, but these plants are energy-intensive and generate significant carbon dioxide emissions (500-850 million tons annually).
• Reverse osmosis generates saltwater brine, which can harm marine habitats; Iran primarily relies on groundwater but is expanding desalination due to drought.

Key Concepts Involved:

• Desalination: Process of removing salt and minerals from saline water to make it potable.
• Reverse Osmosis (RO): A membrane-based technology that uses pressure to separate water molecules from dissolved salts.
• GCC (Gulf Cooperation Council): A regional intergovernmental political and economic union consisting of all Arab states of the Persian Gulf.
