IB ESS Topic 4.2: Access to Freshwater

What is water scarcity?

• Water scarcity is the presence of contaminated water sources within a region.

• Water scarcity is the abundance of water resources within a region.

• Water scarcity is the excessive use of water resources within a region.

• Water scarcity is the lack of sufficient available water resources to meet the demands of water usage within a region.

Discuss the importance of water management in ensuring sustainable access to freshwater.

• Water management has no impact on freshwater access

• Water management plays a key role in maintaining sustainable access to freshwater by addressing issues such as scarcity, pollution, and depletion of water sources.

• Polluting water sources is beneficial for sustainable access to freshwater

• Depletion of water sources is not a concern for sustainable access to freshwater

What is desalination and how does it contribute to increasing freshwater availability?

• Desalination is the process of adding salt to freshwater to increase its availability.

• Desalination is the process of extracting minerals from freshwater to make it saltier.

• Desalination is the process of removing salt and other minerals from seawater to produce freshwater, thus increasing freshwater availability.

• Desalination is the process of converting freshwater into saltwater, reducing its availability.

How does climate change impact access to freshwater?

• Climate change only improves access to freshwater

• Climate change can impact access to freshwater by altering precipitation patterns and distribution.

• Freshwater sources are not affected by climate change

• Climate change has no impact on freshwater access

Explain the concept of water footprint.

• Water footprint is the total volume of freshwater used directly or indirectly to produce goods and services.

• Water footprint is the measurement of the weight of water used in a product

• Water footprint is the footprint left by water on the ground

• Water footprint is the amount of water a person drinks in a day

Discuss the role of technology in improving water management practices.

• Technology in water management leads to increased pollution

• Technology has no impact on water management practices

• Technology enables real-time monitoring, optimization, quality testing, and data-driven decision-making in water management.

• Manual methods are more effective than technology in water management

What are the potential consequences of privatizing water resources?

• Enhanced environmental protection

• Improved access for marginalized communities

• Potential consequences of privatizing water resources include increased costs, lack of access for marginalized communities, environmental degradation, and prioritization of profit over public health and safety.

• Decreased costs for consumers

Describe the process of reverse osmosis in desalination.

• Reverse osmosis involves distillation of saltwater

• Reverse osmosis uses a magnetic field to separate salt from water

• Reverse osmosis is a purely mechanical process with no membrane involved

• The process of reverse osmosis in desalination involves using pressure to push saltwater through a semipermeable membrane, separating the water molecules from the salt and impurities.
