Increasing citizen demands for better environmental quality have led Chile, a party to the Escazu Agreement, to adopt participatory monitoring in environmental assessments, including for odour pollution.

   This work aims to compare the D-NOSES citizen-based odour data collection method with traditional assessment approaches. The study will evaluate the consistency of citizen-reported odour observations using an odour annoyance index. This assessment is crucial to validate the reliability of citizen-generated odour measurements.

   This project developed a methodology using the NASAPP web platform to monitor and analyze odor pollution from a waste management plant in a residential area.

   By combining trained-user data with public participation and advanced analysis, it created an odor impact index and facilitated transparent stakeholder communication. The approach reduced odor complaints by 80% and established a replicable model for environmental conflict resolution, emphasizing community-company-authority collaboration.
