In today’s digital age, citizen science empowers communities to actively contribute to scientific research, enhancing data collection and fostering local engagement. By participating in a Citizen Science App, users contribute valuable observations and data points, collectively building a robust data-set that informs analysis and research. This collaborative approach not only broadens our understanding of complex issues but also accelerates the development of effective solutions.
Examples of successful citizen science initiatives include:
- Tracking bird migration patterns to identify critical habitats for conservation.
- Monitoring water quality to detect pollution hotspots, informing environmental remediation.
- Mapping light pollution to shape policies protecting nocturnal wildlife.
Technology and Collaboration: The Role of iScout Mobile App
Central to STELLA’s citizen science approach is the use of the iScout mobile app, a powerful tool that empowers users to actively participate in pest detection. Currently, the app is being deployed in two Use Case Pilots (UCPs):

The iScout mobile app allows users to:
- Administrate insect traps by specifying trap type, targeted insect, and precise location using the mobile phone’s GNSS sensor.
- Capture and upload photos of sticky cards from traps, which are then analyzed by FieldClimate servers using AI-powered insect detection.

A Collaborative Future for Plant Health
By integrating citizen science with advanced digital technologies, STELLA bridges the gap between research and real-world application. This collaborative approach not only empowers local communities but also contributes to sustainable agriculture, food security, and environmental protection. As STELLA continues to engage growers and stakeholders, it paves the way for a more resilient agricultural ecosystem.
