Water management
Continuous sensors and automated gates can reduce repetitive checking and manual adjustment while keeping the farmer in control of water decisions.
Agriculture & Technology · Case Study
Modernize the farm, not the plantation.
Use technology to make rice and kalo production less labor-intensive.
A lack of manual farm labor should not be treated as proof that Hawaiʻi cannot produce more of its own food. Rice shows how far mechanization and automation can already go. Kalo shows where Hawaiʻi can develop smaller, crop-specific technology that supports local conditions and traditional systems.
The principle
Design agriculture so one skilled worker with modern equipment can accomplish what once required many laborers.
The goal is not to eliminate people from agriculture. It is to move human labor away from repetitive, physically demanding, low-productivity tasks and toward operation, maintenance, crop and livestock expertise, engineering, supervision, and continuous improvement.
“Modernize the farm, not the plantation. Use technology to produce more food with fewer workers while creating higher-skill, better-paying careers.”

A strong candidate for demonstrating highly automated food production.

Research basis: Recent smart-rice research describes unmanned systems spanning tillage, planting, field management, monitoring, harvesting, and machinery management. Autonomous rice harvesting and transport have also been demonstrated in field research. Hawaiʻi would still need to determine which systems make economic sense for local acreage, field sizes, water systems, and varieties.
Kalo
A more specialized engineering challenge, and therefore a Hawaiʻi opportunity.
What can be automated now or relatively soon
- Water-level and temperature monitoring
- Electrically controlled irrigation gates
- Soil and water sensing
- Camera and drone monitoring
- SI-assisted plant-stress and disease detection
- Precision nutrient management
- Small robotic weed control
- Material transport and handling
Where engineering is still needed
- Lightweight wet-condition machines
- Small-scale harvest assistance for local cultivars
- Machines that minimize corm damage
- Equipment suited to irregular terrain and smaller fields
- Affordable systems that fit island farm economics
- Technology that works with, rather than unnecessarily replaces, traditional loʻi systems
Mechanization is not hypothetical: Taro-harvesting machines and related harvesting systems are already being developed internationally. A 2021 Japanese study reported a mechanized taro harvesting system with work efficiency about three times that of the conventional system. That is evidence of potential, not proof that an existing machine fits Hawaiʻi kalo production.
Wetland kalo
Automate the labor around the loʻi without unnecessarily destroying the loʻi system.
Targeted crop monitoring
Cameras, drones, and SI can help identify stress, disease, weeds, or other anomalies so the farmer can focus attention where it is needed instead of inspecting every plant with equal frequency.
Material handling
Small tracked or lightweight equipment can help move amendments, huli, tools, and harvested corms, reducing physically demanding carrying and repetitive transport.
Dryland kalo
Adapt root-crop machinery to Hawaiʻi scale.
Dryland kalo should generally offer a clearer path to mechanization. Equipment used for other root crops provides a starting point for lifting corms, separating soil, conveying harvested crops, loading containers, and moving harvest out of the field. The key is not importing oversized continental machinery, but engineering smaller systems for local cultivars, soils, terrain, field sizes, and economics.
Economic-development opportunity
Create a Hawaiʻi agricultural robotics and island-technology industry.
Crops such as kalo, ʻulu, tropical fruit, and smaller island production systems may be underserved by equipment companies focused on continental commodity agriculture. That gap can become an economic opportunity for Hawaiʻi.

Kalo robotics
Develop harvesting assistance, wet-field mobility, crop monitoring, water control, and material-handling systems around Hawaiʻi conditions.
Rice automation
Adapt autonomous and semi-autonomous systems to island field scale, local water systems, and viable local rice-production models.
Tropical and island exports
Equipment, software, sensors, and operating expertise developed for Hawaiʻi may also be useful to other tropical and island economies with similar scale and crop constraints.
UH connection: Hawaiʻi is not starting from zero. UH already has active work in agricultural robotics, smart sensors, farm drones, machine vision, automated planting and harvesting, and advanced irrigation. A state strategy can focus on moving more of that work from research to prototypes, demonstration, commercialization, and local industry.
Workforce development
Modernization changes the jobs Hawaiʻi needs.
Agricultural techniciansRobotics operatorsDrone operatorsIrrigation techniciansMechanicsEquipment techniciansAgricultural engineersCrop specialistsData & sensor techniciansFood-processing techniciansElectronics techniciansManufacturing & repair workers
Career and technical education, UH community colleges, apprenticeships, and workforce programs should align with these jobs. Agricultural self-sufficiency should not mean creating thousands of low-wage manual jobs. It should mean building a modern productive economy in which technology raises output per worker and creates skilled careers around production, machinery, processing, and logistics.
Self-sufficiency
Technology changes the answer to “Who will work the fields?”
Hawaiʻi should not abandon local production because the old labor model no longer works. Rice illustrates what extensive mechanization can already accomplish. Kalo illustrates where Hawaiʻi can preserve culturally important cultivation while modernizing water management, monitoring, transport, processing, and eventually more of the harvest. The common goal is fewer labor hours per unit of food produced and more skilled work around the system.

Research limitation: None of these sources establishes that Hawaiʻi can fully automate local rice or kalo production today, or that any particular machine is economically viable here. They establish that rice automation is technically advanced, taro mechanization is real and improving, and Hawaiʻi already has relevant agricultural-technology capacity. Local prototypes and field trials are still necessary.
