Water Crisis in the Maldives: Desalination and Rainwater Harvesting as Solutions

The video discusses the water crisis on Difushi Island, where seawater has contaminated the freshwater table, making it unusable. As a short-term solution, desalination units using reverse osmosis are deployed to provide drinking water. However, these units are temporary, and a long-term solution involves rainwater harvesting. By collecting monsoon rains in water tanks, the islanders can have a sustainable source of freshwater.

What caused the freshwater table on Difushi Island to become unsuitable for drinking?

• Pollution from industrial waste

• Drought conditions

• Overuse of water resources

• Flooding with seawater

What is the primary method used in the desalination units to purify seawater?

• Reverse osmosis

• Filtration through sand

• Chemical treatment

• Boiling and condensation

How many people can one desalination unit supply with water each day?

• 100 people

• 250 people

• 500 people

• 1000 people

What is a potential long-term solution for the water crisis on Difushi Island?

• Harvesting rainwater

• Drilling deeper wells

• Importing water from other regions

• Building more desalination plants

How much rainwater can a 2,500-liter tank provide for a family of four?

• 1 month

• 3 months

• 2 months

• 6 months
