Interesting Facts & Summary
The 'Lifeline' of Island Survival
In environments with extreme freshwater scarcity, these nations treat desalination as core national security. Interestingly, it is not just large-scale plants; countries like the Maldives and the Marshall Islands achieve high per capita coverage through distributed small-scale RO units.
Key Comparison:
- Middle Eastern Island States (e.g., Bahrain): Driven by industrial needs with massive individual plant capacities.
- Pacific Island Nations: Climate-driven, focusing on combating sea-level rise and groundwater salinization.
