Paearu Angitu · Success Criteria
- I can define each of the five key concepts in my own words — not copied from the card
- I can give a specific example for each concept from the unit (kūmara / rice / flour / cash crops / Waikato)
- I understand what all four rubric criteria require — not just Content, but also Social Analysis, Visual Communication, and Scarcity/Trade-offs

Ngā Ariā Matua · Key Concepts
Scarcity
When there isn't enough of something to meet everyone's wants. Forces choices. Example: limited land to grow both food and cash crops.
Trade-off / Huri Utu
Giving up one thing to get another. Example: growing coffee for money instead of food for your family — you gain income but risk food security.
Cash Crop / Hua Moni
A crop grown for export/profit, not for local food. Examples: coffee, cocoa, palm oil, cotton, tea, sugar.
Supply Chain / Ara Tuku
The journey from farm to consumer: Farmer → Collector → Exporter → Corporation → Supermarket → You. Each step adds cost and distance.
Staple Food / Kai Matua
Basic food that people rely on daily — rice, wheat, kūmara. Different from cash crops: staples feed people, cash crops earn money. When scarcity hits, staple foods are the last to be traded away.

Unit Case Studies
Kūmara — Week 2
Māori innovation: rua kūmara storage pits solved scarcity by preserving food through winter. Kaitiakitanga as resource management — harvesting cycles, rāhui to prevent over-extraction.
Rice — Week 3
Staple food for 3.5 billion people. Trade routes connected cultures across Asia and Africa. Shows how scarcity of arable land drives agricultural innovation across generations.
Flour and Colonisation — Week 4
Wheat flour replaced traditional Māori foods — creating dependency and new forms of scarcity. A trade-off imposed rather than chosen: land for flour, mana for survival.
Climate Change — Week 6
Extreme weather (drought + flood) affects food production globally and locally. Waikato River case study: flooding destroys crops; drought reduces river levels and irrigation.
Ngā Ārahitanga Tere · Quick Tips for the Assessment
Aronga Mātauranga Māori
Kaitiakitanga — guardianship and stewardship — is not just a cultural value. It is a practical economic system. Long before the word "sustainability" entered global discourse, Māori communities in Aotearoa had developed sophisticated responses to scarcity: rāhui (seasonal restrictions on harvesting), rua kūmara (underground storage systems), seasonal rotation of fishing grounds, and reciprocal sharing obligations that prevented over-accumulation. These are not primitive practices — they are advanced resource management strategies that anticipated modern ecological economics.
When you study this unit, you are studying two economic traditions simultaneously: the mainstream Western tradition of markets, supply chains, and cash crops — and the Māori tradition of kaitiakitanga, reciprocity, and long-term sustainability. Understanding both, and where they conflict or align, is what makes you a genuinely well-educated thinker about food, climate, and justice.

Aronga Rerekē · Differentiated Pathways
Tīmata · Entry Level
Focus on Scarcity and Trade-off. Can you give one example of each from the unit? Use this card to check your definitions before writing. You don't need all five concepts — understand two really well first.
Paerewa · On Level
Know all five concepts with a unit example for each. Use the assessment reminder section to self-check your poster against all four criteria. Identify where kaitiakitanga appears in your case study.
Tūāpae · Extension
Write your own definition for each concept that connects it explicitly to a Māori example from the unit. Then answer: "How does kaitiakitanga resolve the tension between scarcity and long-term sustainability in a way that the free market does not? What does this suggest about the limits of mainstream economic thinking?"
📋 Teacher Planning Snapshot
Ngā Whāinga Ako — Learning Intentions
Students will engage with this resource to investigate the intersection of kai (food), culture, and climate — exploring how mātauranga Māori approaches to food production, preservation, and distribution offer powerful responses to contemporary food security and climate challenges in Aotearoa New Zealand and globally.
Ngā Paearu Angitū — Success Criteria
- ✅ Students can explain how traditional Māori kai practices (maramataka, kūmara cultivation, rāhui) embody ecological knowledge and food security principles.
- ✅ Students can connect kai culture and climate scarcity to contemporary community action and food sovereignty movements.
Differentiation & Inclusion
Scaffold support: Provide graphic organisers that map traditional kai practices to modern food security concepts at the entry level. Offer extension tasks asking students to research a specific iwi's traditional food system and evaluate its contemporary relevance, or to investigate a local food sovereignty initiative.
ELL / ESOL: Pre-teach domain vocabulary (food sovereignty, food security, kaitiakitanga, rāhui, maramataka) using visual diagrams and real-world examples. Draw connections to students' own cultural food traditions — these are valid entry points into the unit's themes. Allow oral or visual presentation of learning as alternatives to written tasks.
Inclusion: Kai is a universal human experience — all students have a relationship with food, seasonality, and sharing. Neurodiverse learners benefit from concrete, hands-on engagement with these concepts (e.g., examining a kūmara, mapping seasonal foods). Acknowledge diverse economic circumstances sensitively when discussing food security. Choice in how students demonstrate understanding (written, visual, oral) supports inclusive assessment.
Mātauranga Māori lens: The maramataka — the Māori lunar calendar — is one of Aotearoa's most sophisticated environmental data systems, encoding centuries of ecological observation about planting, harvesting, fishing, and weather patterns. Kūmara cultivation in pre-colonial Aotearoa was a feat of agricultural knowledge adapted to a new climate. Rāhui (temporary resource restrictions) is indigenous resource management — conservation before conservation. Kaitiakitanga frames the relationship between people and kai not as extraction but as reciprocal guardianship. These are not historical curiosities — they are living solutions to contemporary problems.
Prior knowledge: Students benefit from foundational understanding of climate change and food systems. No specialist mātauranga Māori knowledge required for entry-level engagement — the unit builds this knowledge progressively.
