Geodesic dome schools a pathway to season extension and food security for Native Americans of the Wind River Indian Reservation (WRIR-Wyoming)

Commodities

• Vegetables: carrots, cucurbits, peppers

Practices

• Education and Training: on-farm/ranch research
• Sustainable Communities: food access and security, leadership development

The growing season in Wyoming can range from 30 to 120 days due to unpredictable weather conditions. Extending the growing season is crucial for addressing food insecurity in many western food desert regions. Implementing geodesic domes as a season extension tool on the Wind River Indian Reservation (WRIR) could enhance food production, improve food security, and provide economic opportunities through the sale of surplus produce. Documenting the benefits of domes for season extension will support the case for their wider adoption in the future.

Since 2008, Extension Educator Jeff Edwards has partnered with others to explore methods for season extension. After numerous trials, geodesic domes have shown increased structural durability and extended growing periods for successful crop cultivation. Although 31 domes are currently in use, including several on the WRIR, schools and daycares, the lack of control over production and harvest variables makes accurate data collection difficult at those locations, however, anecdotal evidence highlights their effectiveness.

To enable accurate, replicable data collection, three WRIR producers will construct domes, use identical growing media, production practices, and cultivate similar crops in both internal and external raised beds. Research focuses on measuring the extended growing season, input costs, crop yields, and monetary value of each crop, to identify best practices to facilitate future adoption of geodesic dome production. A remote data collection system, and support of a research technician will help ensure accuracy of data collected.

Outreach will include hands-on dome construction training, a manual, social media engagement, and presentations to other producers. 

Objectives - Educational

1. 1. Conduct a needs assessment to determine producer and other WRIR grower resources needed.
   2. Equip producers with skills to build geodesic domes and raised beds through dome schools.
   3. Teach producers to install irrigation systems and monitor pest and crop production. 
   4. Facilitate knowledge-sharing through virtual “show and tell” meetings during the growing season.
   5. Provide educational displays at the Wind River Farmers Market and public areas.
   6. Present project findings at professional meetings, workshops, and to stakeholders.

Objectives - Research 

1. 1. Determine growing season extension using passive geodesic dome greenhouses. 
   2. Compare crop production differences between interior and exterior raised beds. 
   3. Identify differences in inputs required for indoor and outdoor crop production. 
   4. Assess pest pressure and management differences between indoor and outdoor crops. 
   5. Evaluate the cost and income potential of crop production using passive geodesic domes.
