Controlled-environment agriculture
**Technical Implementation in Controlled-Environment Agriculture:**
– Controllable variables: temperature, humidity, CO2 levels, light conditions.
– Cultural variables: water quality, nutrient concentration, pH levels, cropping duration, density, cultivar selection.
– Range of CEA facilities: from fully controlled enclosed systems to automated glasshouses.
– Crops suitable for CEA: tomatoes, leafy greens, herbs, and other crops.
– Inclusion of low-tech solutions like modified environment agriculture with plastic coverings.
**Motivation and Advantages of Controlled-Environment Agriculture:**
– Purpose of CEA: food production, pharmaceuticals, nutriceuticals, algae for food, biofuels.
– Benefits of CEA: enhanced food safety, supply security, market stability, reduced labor through automation.
– Research benefits: isolation of specific production aspects, increased efficiency, reduced pests, diseases, and resource usage.
– Advantages over traditional farming: water and space efficiency, year-round production, weather event protection.
**Urban Impacts of Controlled-Environment Agriculture:**
– Benefits of urban CEA: consistent, local, and accessible fresh produce.
– Impact on underserved communities: training, employment, business opportunities.
– Addressing food accessibility issues and creating a stable market for fresh produce.
– Meeting the rising demand for quality fruits and vegetables in urban areas.
