- Actionable insight: Even if you’re growing on a small scale, drones are becoming affordable and could help monitor your urban garden more effectively.
5. Dealing with Climate Change and Food Security
The COVID-19 pandemic exposed weaknesses in global food systems, especially in cities. Smart farming technologies can help urban farmers become more resilient, conserving resources while maximizing output. For example, AI-driven systems can predict climate patterns and help farmers plan planting seasons more effectively.
- Important takeaway: Investing in smart technology can help reduce your carbon footprint and make your garden more efficient.
Overcoming Challenges in Urban Farming
Even though smart farming technologies offer immense potential, challenges like the cost of devices, access to resources, and data privacy concerns need attention. Additionally, the infrastructure required for large-scale urban farming is still developing in many cities. For instance, food storage and processing facilities need improvement to prevent waste, as seen in cases where Canadian farmers had to dump millions of liters of milk during the pandemic due to a lack of storage solutions.

This passage provides an extensive overview of the applications of drones and remote sensing technologies in agriculture, environmental monitoring, and nature conservation. Here are the key points and technologies discussed:
Agriculture:
- GPS in Agricultural Equipment:
- Early examples of GPS in farming include John Deere tractors, which help farmers avoid covering the same field twice, saving water, fuel, and pesticides.
- Satellite Imagery and Cloud Computing:
- Researchers like Paula Marti use high-quality satellite imagery (30 cm by 30 cm resolution) and deep learning algorithms to monitor forests and vegetation for conservation. Cloud computing and distributed volunteer computing (30,000 computers worldwide) are often used for complex data analysis due to the need for significant computational power.
- Drones in Precision Agriculture:
- Definition and Structure: Drones, also known as UAVs (Unmanned Aerial Vehicles), are equipped with sensors, GPS, cameras, and sometimes AI to perform various tasks autonomously or semi-autonomously.
- Applications: Drones are widely used for tasks such as:
- Spreading seeds, spraying pesticides, monitoring crops, generating 3D maps for soil analysis, and precision water and fertilization applications.
- Drones can gather data via multispectral and thermal cameras and LiDAR (Light Detection and Ranging).
- Benefits include flexibility, affordability, and high-resolution image capturing. Drones are not affected by weather conditions like satellites and can operate with centimetre-level image resolution, ideal for detecting crop health and optimizing inputs (fertilizers, pesticides).
- Limitations: Small drones have limited payload capacity, low resolution, short flight endurance, and safety/security issues.
- Innovative Applications:
- Pollination: Drones are being developed to mimic natural pollinators, such as bubble-blowing drones that can artificially pollinate crops.
