The future: hydroponics and aquaponics
I can investigate how hydroponic and aquaponic systems function and explain their potential to revolutionise sustainable farming.
Lesson details
Key learning points
- Hydroponics uses nutrient rich water to grow plants without soil.
- Aquaponics uses water from fish farming to nourish plants.
- They require fewer inputs: no soil, minimal water, less chemicals and produce higher yields than traditional farming.
- In the Zaatari refugee camp, aquaponics provided over 70% increase in fresh food for farmers.
- Hydro and aquaponics do have high setup costs, energy demands, and technical complexity, which can limit accessibility.
Keywords
Hydroponics - using nutrient-rich water to grow plants without soil
Aquaponics - using nutrient-rich water from the farming of aquatic animals to nourish plants
Sustainability - meeting the needs of the present without compromising the ability of future generations to meet their own need
Common misconception
Hydroponic and aquaponic systems are completely self-sustaining or maintenance-free.
Require regular monitoring, energy inputs and human intervention to stay productive.
Try some basic hydroponics in the classroom using a mint or basil cutting and a jar of water, students will be able to observe the roots developing and the plant growing without soil over time.
