Where cutting-edge satellite technology guides the planting of ancient medicinal flora, and digital maps become the canvas for reviving traditional knowledge.
This isn't a vision of the future—it's happening today on iwi-run farms across Aotearoa New Zealand, where Geographic Information Systems (GIS) are revolutionizing agricultural practices through a powerful synergy of indigenous agroecology and precision technology 3 .
The integration of GIS technology in agriculture represents more than just a technical upgrade; it's a transformative approach to land management that honors the Māori concept of kaitiaki (guardianship) while addressing modern challenges of sustainability and productivity 3 .
A Geographic Information System (GIS) is a framework designed to capture, store, manipulate, analyze, manage, and present spatial or geographic data 1 . In practical terms, GIS allows farmers and land managers to create multi-layered interactive maps that visualize complex data and enable sophisticated spatial analysis .
The power of GIS lies in its ability to synthesize diverse data streams into actionable insights, helping farmers optimize resource use, reduce environmental impact, and improve productivity 6 .

While GIS technology offers benefits to any farming operation, its application on iwi-run farms represents a particularly significant evolution. For Māori land trusts, GIS provides more than just economic advantages—it serves as a tool for cultural preservation, community engagement, and the expression of kaitiakitanga (guardianship) 3 .
"Māori trust farms often envision implementing sustainable agricultural systems utilizing organic, biological, or low-chemical methods to decrease environmental impact." 3
Integrates traditional knowledge with modern technology
Visual tools make abstract initiatives clear to community members
Helps navigate the shift from chemical-based agriculture
A groundbreaking study conducted at Te Kaio farm, a 449-hectare sheep and beef operation on Banks Peninsula, exemplifies the innovative application of GIS for medicinal flora cultivation 3 . Researchers sought to apply GIS-based multi-criteria analysis (MCA) to indigenous agroecology-based management to identify optimal growing areas for native plants with traditional medicinal properties, known as rongoā rākau 3 .
Traditional Uses: Antimicrobial properties, wound healing
Growing Requirements: Well-drained slopes, moderate moisture
Traditional Uses: Skin conditions, respiratory issues
Growing Requirements: Similar to mānuka but tolerates poorer soils
Traditional Uses: Various medicinal applications
Growing Requirements: Lower slopes, higher soil moisture
Traditional Uses: Various traditional applications
Growing Requirements: Versatile—wide range of conditions
The research team employed a sophisticated methodology that honored both scientific rigor and traditional knowledge 3 :
Key land-based criteria affecting plant growth, including elevation, slope, aspect, soil moisture, and soil pH.
Data layers for each criterion developed using digital elevation models, soil surveys, and field measurements.
Traditional knowledge about plant preferences incorporated through consultation with cultural experts.
Weighted linear combination technique to analyze spatial data according to specified criteria.
Generated suitability maps for seven different medicinal plant species with thresholds for optimal areas.
Beyond medicinal flora cultivation, GIS supports a wide range of applications relevant to iwi-run farms, particularly in advancing agroecological principles and enhancing public access.
GIS can map existing vegetation and plan connections between natural areas, supporting biodiversity conservation alongside agricultural production through ecological corridor planning.
GIS provides powerful visual tools for communicating plans and concepts to community members, making abstract initiatives tangible and understandable 3 .
| Application | Estimated Adoption Rate | Estimated Yield Improvement | Sustainability Impact |
|---|---|---|---|
| Precision Farming | 75% | 20-25% | High |
| Crop Health Monitoring | 70% | 15-20% | High |
| Soil Analysis | 60% | 10-13% | High |
| Irrigation Management | 65% | 15-18% | High |
| Robotics Integration | 60% | 18-22% | High |
The integration of GIS technology on iwi-run farms represents more than an agricultural innovation—it's a powerful fusion of tradition and technology that creates new possibilities for sustainable land management.
The experience at Te Kaio farm demonstrates that GIS is far more than a precision agriculture tool—it's a bridge between worlds 3 .
Enables the translation of traditional ecological knowledge into practical, spatially-aware management decisions 3 .
Offers a promising path toward sovereign food systems that are economically viable, environmentally sustainable, and culturally appropriate.
By harnessing the power of spatial analysis while remaining grounded in traditional values of kaitiakitanga, these communities are growing a future that honors both their ancient roots and their contemporary aspirations.
