Can Community Farms Feed People?

0–5 min | Starter – Recall &Framing the Question

Quick recap (teacher-led):

• From last lesson: What is a community farm?
• What types of food do they usually grow?

Key question on board:

Can community farms realistically produce enough food for all local people?

Students vote yes / no / maybe and one reason.

5–15 min | Section A: Scaling Up Food Production

Teacher Input – Limits of Community Farming (5 mins)

Explain:

• Community farms often focus on:
  • Fruit and vegetables,
  • Some raise livestock or are mixed farms
• They usually:
  • Use smaller areas of land
  • Prioritise sustainability and education over profit

Key limitation:

Even very productive community farms usually cannot supply enough food for everyone in towns or cities.

Video: TED-Ed – Can We Create the “Perfect” Farm? (7 mins)

🎥 TED-Ed animation (7:09) Introduces how high tech, small-scale/community farms plus a move to a plant-based diet offers potential solutions for feeding the population and protecting the planet. https://www.youtube.com/watch?v=xFqecEtdGZ0

While watching, students identify:

• One challenge with current food systems
• One idea for improving food production

15–25 min | Can Community Farms Feed Local Populations?

Guided Discussion (10 mins)

Teacher explains (KS3-appropriate):

• In rural or less densely populated areas, community-scale farming can sometimes:
  • Feed local people
  • Be more self-sufficient
• In the UK:
  • There are almost 70 million people and limited land
  • Most land is already used for:
    • Animal farming
    • Animal feed crops

Important clarification:

• The UK imports about 40-50% of its food. Self-sufficiency has declined from highs in the 1980s. The UK could theoretically support food needs only under specific conditions, such as:
  • Diets shifting towards more plant-based foods
  • Efficient use of land and growing crops for humans/not raising animals
  • Reduced food waste

Prompt: If land is limited, how else could food production increase?

25–35 min | Section B: Farming Adaptations for Food Security

Introducing Technological Solutions (5 mins)

Hydroponics

• Growing plants without soil
• Nutrients delivered through water
• Uses less space and water
• Faster growth
• Year-round production

Vertical farming

• Growing crops in stacked layers
• Maximises production in small areas
• Often used indoors
• Controlled environment
• Less affected by weather

👉 These systems are often combined to increase yield.

Video: Farming Indoors (5 mins)

🎥 BBC World Service – The Farmers Bringing Their Fields Indoors (4:27) For an introduction to indoor vertical farms watch: https://www.youtube.com/watch?v=t0PheK2_flU

Students note: One advantage, One limitation (e.g. energy use, cost, crop types)

35–45 min | Activity – Designing a Food System Solution

RHS Challenge (10 mins)

Using the RHS resources, in pairs or small groups, students choose one challenge either:

Option A:  Develop a Hydroponic Garden : https://www.rhs.org.uk/education-learning/school-gardening/resources/gardening-skills/growing-crops-with-hydroponics

• Where would it be used (school, city, warehouse)?
• What crops would be grown?
• How does it save space?

Option B:  Small Vertical Garden (using upcycled materials): https://www.rhs.org.uk/education-learning/school-gardening/resources/planet-friendly/vertical-gardening

• What materials could be reused?
• Where could it be built?
• Who could benefit from the food grown?

Students sketch or bullet-point ideas.

45–50 min | Sharing & Realism Check

Groups briefly share:

• Our current farming system is harming our environment, and no single solution is likely to work alone
• Food security may require multiple approaches. 

On their tables, students rank these 8 ideas to most and least desirable: *Reduce meat consumption, *Adopt a vegan diet, *Join or support community farms, *Grow your own food at home, *Reduce food waste, *Support regenerative/ organic type farms, *Buy seasonal, local fruit and veg, *Change nothing.

50–55 min | Final Plenary – Exit Question

Students answer in writing:

Can community farms alone feed local people, or must they be part of a wider food system? Explain your answer using evidence from the lesson.

Encourage reference to:

• Population size/culture
• Land use
