What students need to be able to do

• Describe which parts of the world have more water available than they need (making them water-secure) and which fall short (leaving them water-insecure), and the global pattern this creates.
• Explain why global water consumption is rising, covering both economic development (rising demand from industry, agriculture and household use as incomes grow) and population growth.
• Explain how each of the following factors can affect a place's water availability: climate (rainfall patterns and variability), geology (how easily rock allows water to be stored or to pass through it), pollution of supply (contamination reducing usable water), over-abstraction (withdrawing water faster than it is naturally replenished), limited infrastructure (inadequate systems for collecting, storing, treating or distributing water), and poverty (ability to afford water access or treatment).
• Explain the range of impacts that water insecurity can cause: disease spread through contaminated water and pollution of water sources, reduced food production, reduced industrial output, and a heightened risk of conflict when users, regions or countries are competing for more water than actually exists.
• Give an overview of strategies used to increase water supply: diverting existing supplies and increasing storage capacity; building dams and reservoirs; transferring water between regions; and desalination (removing salt from seawater to make it usable).
• Use a named example of a large-scale water transfer scheme to explain both the advantages it has brought and the disadvantages or drawbacks associated with it: flagged here as a required named example; the specific real-world scheme is composed separately at bundle-build time, grounded in this requirement.
• Explain the range of approaches that can move water supply towards a more sustainable future: water conservation (reducing unnecessary use), groundwater management (using underground water sources responsibly so they are not depleted), recycling water, and using "grey water" (reusing gently-used water, such as from sinks or showers, for purposes that don't need fully clean water).
• Use a named example of a local scheme in a lower-income country or newly emerging economy that increases sustainable water supply, and explain how it does so: flagged here as a required named example; the specific real-world scheme is composed separately at bundle-build time, grounded in this requirement.

Case studies and examples needed

• A large-scale water transfer scheme, used to show both its advantages and its disadvantages.
• A local scheme, based in a lower-income country (LIC) or newly emerging economy (NEE), that increases sustainable water supply.

Geographical skills used

• Interpreting choropleth or graduated-symbol maps showing global water surplus/deficit patterns.
• Reading and comparing statistical data on water consumption, availability, or access trends over time.
• Interpreting diagrams of specific infrastructure (e.g. a labelled dam and reservoir system, a water transfer scheme route map, a desalination process diagram).

Where students go wrong

• Assuming water insecurity only affects places with low rainfall, rather than understanding factors like pollution, over-abstraction, and infrastructure can cause insecurity even where rainfall is adequate.
• Confusing "increasing water supply" strategies (which raise the volume available) with "sustainable water supply" strategies (which reduce waste or protect existing sources): these are two distinct parts of the specification, not one blended list.
• Assuming a large-scale water transfer scheme only benefits the receiving area, and overlooking the disadvantages it can cause in the source area or environment.
• Believing desalination is a simple, low-cost solution, rather than understanding it is energy-intensive and expensive relative to other supply strategies.
• Confusing "grey water" reuse with wastewater/sewage treatment: grey water specifically refers to gently-used water such as from sinks, baths or washing machines, not water contaminated with sewage.

How it gets asked in the exam

"Explain why global demand for water is increasing", "Explain how [a named factor] can affect water availability", "Explain one advantage and one disadvantage of [named water transfer scheme]", "Assess the extent to which [named local scheme] provides a sustainable water supply", "Explain how water insecurity might lead to conflict between countries or regions".

Key vocabulary

Water security, water insecurity, water surplus, water deficit, water stress, over-abstraction, geology, waterborne disease, water transfer, desalination, reservoir, water conservation, groundwater, grey water.

Assumed prior knowledge

• Resource Management Overview (this taxonomy's topic 15), particularly the UK-specific water-supply-and-demand content, which this topic extends to a global scale.
• General awareness from KS3 geography or science of the water cycle, since factors like geology and over-abstraction assume basic understanding of how water moves through and is stored in the environment.

How Speca scaffolds this topic

• Use a consistent factor-sorting grid (climate / geology / pollution / over-abstraction / infrastructure / poverty) as a recurring scaffold across explanation tasks, mirroring the equivalent structure used for the Food option's six factors so students transfer the same approach if they encounter both.
• Provide a clear two-column "increase supply vs. sustainable supply" table populated with each named strategy, so students don't conflate the two strategy types.
• For the two required named examples, use a single consistent advantages/disadvantages (or "how it works / why it's sustainable") template reused across both, so the skill of writing about a case study transfers rather than being relearned per example.
• Use a single labelled diagram of a water transfer scheme (source, transfer route, receiving area) as a reusable visual anchor, since transfer schemes are often the hardest strategy for students to picture without a map.
