Define resource stewardship.
Managing resources **responsibly** so they are used carefully and **kept available for future generations**.
Define a circular economy.
An economy that **reuses, repairs and recycles** materials to keep them in use and cut waste.
Define a linear economy.
The 'take, make, dispose' model that turns resources straight into **waste**.
Define an ecological footprint.
The land and water area needed to supply a population's resources and absorb its waste.
Name three features of a circular economy.
**Designing out waste**, **reuse/repair**, and **recycling materials** (also renting/sharing, renewable inputs).
How can renewables shrink an ecological footprint?
Clean power cuts the carbon from fossil fuels, so less land is needed to absorb it.
How can renewables enlarge an ecological footprint?
Solar/wind farms take up land and mining their metals uses extra resources.
Two ways to strengthen water security?
Recycle/reuse water and cut leaks (also storage/harvesting and desalination).
One economic advantage of the circular economy?
It cuts demand for new raw materials, lowering costs and reliance on imports.
Two reasons the circular economy is hard to apply?
It needs costly new systems and people must change attitudes to **owning** products.
Named circular-economy example?
The **Netherlands** aims to be fully circular by 2050, reusing materials and designing for repair.
What does a 'to what extent' essay need for the top band?
Both sides argued, a **named example**, comparison with alternatives, and a clear **judgement**.
3.3.211 cards
Who was the population-resource optimist?
**Boserup** — she argued population pressure drives innovation that grows more food.
Who was the population-resource pessimist?
**Malthus** — he feared population would outgrow food, causing famine.
Sum up Boserup's view in one phrase.
'**Necessity is the mother of invention**' — more people forces new ways to grow more food.
How does Boserup differ from Malthus on food supply?
Malthus saw food as **fixed**; Boserup saw it as **flexible**, rising with demand through technology.
Define carrying capacity.
The largest population an area can support with its available resources.
Name two ways resources are developed to grow more food.
High-yield crops (Green Revolution) and **irrigation** — also mechanisation, fertiliser, land reclamation.
What did the Green Revolution do?
Introduced **high-yield** wheat and rice varieties that sharply raised grain output (e.g. India).
Why is irrigation a way of developing resources?
It brings water to dry land, turning barren ground into productive farmland and raising food output.
Define sustainability.
Meeting present needs without preventing future generations from meeting theirs.
How can data on food vs population support Boserup?
If **food per person rises** over time, food has out-grown population — backing the optimist, not Malthus.
In a 4-mark Explain on Boserup, what earns the marks?
**Two** developed points, each linking a feature/method to **more food production** (1 + 1 per point).
