Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What is a sustainable food supply?

    Model answer

    One that feeds people today without damaging the soil, water and wildlife that future generations will need in order to feed themselves.

  2. 2

    What is organic farming?

    Model answer

    Farming without manufactured fertilisers and pesticides, using manure, compost and crop rotation instead to keep the soil fertile and control pests.

  3. 3

    Why is organic farming considered sustainable, and what is its main drawback?

    Model answer

    It protects soil structure and wildlife and keeps chemicals out of rivers, but its yields are lower so more land is needed and the food costs more to buy.

  4. 4

    What is permaculture?

    Model answer

    Designing a farm or garden to work the way a natural ecosystem does, so that its plants, animals, water and soil support one another with very little brought in from outside.

  5. 5

    Give two features of a permaculture system.

    Model answer

    Many different crops grown together rather than a single crop, and water and organic waste recycled on site through rainwater harvesting and composting.

  6. 6

    What are urban farming initiatives?

    Model answer

    Schemes that grow food inside towns and cities, on rooftops, allotments, derelict ground and community gardens.
