Botany · Horticulture and Landscaping
In an integrated urban farming project where both vertical gardens on building walls and floating gardens on adjacent water bodies are proposed, the project report must highlight limitations and risks for long-term sustainability. Which of the following combinations best reflects realistic challenges that managers should anticipate for both systems?
- 1No risk of structural load issues, no possibility of nutrient imbalance, and no chance of pest or disease outbreak in either system.
- 2Potential structural load and leak risks for vertical installations, possible raft instability and decomposition for floating gardens, and for both systems the need for regular nutrient monitoring, pest and disease management, and timely replacement or reinforcement of growing media.✓
- 3Only floating gardens have problems, because vertical gardens are permanent and maintenance-free once planted.
- 4Both systems are prohibited in all urban areas due to universal legal bans, so no practical challenges arise in real projects.
Correct answer
Potential structural load and leak risks for vertical installations, possible raft instability and decomposition for floating gardens, and for both systems the need for regular nutrient monitoring, pest and disease management, and timely replacement or reinforcement of growing media.
