Urban Farming: Methods, Benefits and Role of Business
Why in the news
A study published in Sustainability argued that urban farming can ease climate change, food scarcity and pollution while improving food security, public health and community ties.
Why it is needed
- Conventional farming needs plenty of land, water and resources, often causing deforestation and pollution.
- Urban farms need less land: rooftops, balconies and vacant plots can grow food.
- Shorter chains are safer from climate disasters; controlled environments give year-round fresh food.
- Urban farms help cool cities and clean the air.
| Method | How it works |
|---|---|
| Hydroponics | Plants grown in nutrient-rich water, not soil; faster growth, saves water |
| Vertical farming | Crops in stacked indoor layers under controlled conditions |
| Aquaponics | Fish waste feeds plants; plants clean water for fish |
Waste is also handled by composting food scraps or converting them to energy.
Benefits
- Empty spaces become green areas that help mental health.
- Community gardens build socialising and skill-sharing.
- Jobs and training in sustainable farming, business and technology.
- Lower carbon emissions from less food transport.
Way forward
- Renewable energy, organic fertilisers and waste-to-energy can raise efficiency.
- Governments and businesses should back policy and innovation.
- Business investment: hydroponics, smart irrigation, urban green initiatives, and partnerships with experts and farmer cooperatives.
Exam angle
- Soil-less growing in nutrient water: hydroponics.
- Fish plus plants system: aquaponics.
