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 unusable?

• Pollution from industrial waste

• Drought conditions

• Overuse by the local population

• Flooding with seawater

What technology is used in the desalination units to make seawater drinkable?

• Ion exchange

• Reverse osmosis

• Filtration

• Distillation

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 to the water crisis mentioned in the video?

• Rainwater harvesting

• Importing water from other countries

• Building more desalination plants

• Drilling deeper wells

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

• 6 months

• 3 months

• 2 months

• 1 month
