The goal

Project Context.

Community forestry is a cornerstone of environmental conservation in Nepal. However, the management committees often rely on outdated paper records for tracking forest resources, boundaries, and member interactions. The goal of this project was to digitize these processes with a mobile application accessible to committee members in remote areas.

The application needed to map forest boundaries, log resources (like timber and non-timber forest products), and manage committee meeting records. A critical requirement was offline functionality, as many forest areas lack reliable cellular network coverage.

How it was built

Architecture & Tech Stack.

Frontend (Flutter): The mobile app was built with Flutter to ensure cross-platform availability. We heavily utilized `sqflite` for robust local data storage, allowing users to create records and drop map pins entirely offline.

Backend (Django): A Django REST Framework backend served as the central data repository. It handled synchronization, ensuring that when users returned to areas with connectivity, their local changes were seamlessly merged with the central database.

Mapping: Integration with Google Maps allowed users to define forest boundaries and mark specific resource locations using their device's GPS.

Technical hurdles

Challenges & Solutions.

Challenge: Offline Data Synchronization

Managing data conflicts when multiple users update the same records offline and later synchronize with the server.

Solution

Implemented a robust synchronization protocol using timestamps and unique identifiers (UUIDs) generated on the device. The backend resolves conflicts using a “last-write-wins” strategy or flags complex conflicts for manual review by an administrator.

Challenge: Precise Boundary Mapping

Allowing users to accurately draw and save complex forest boundaries (polygons) on a mobile device interface.

Solution

Developed a custom map interaction flow where users can walk the perimeter of a forest and drop pins at key vertices, or manually tap the map to create polygons. The coordinates are stored locally and synced as GeoJSON data to the backend.

Results

The Outcome.

The Forest App significantly improved the efficiency of community forestry management. Digitized records replaced fragile paper logbooks, and the offline-first approach ensured that the app was genuinely useful in the field.

The app is published on the Google Play Store, where committee members can install it directly onto their own devices.

Next steps

Want Something Like This.

The service behind it

UUID-based conflict resolution, GeoJSON boundaries captured on foot, and a Django REST backend that merges it all when a signal returns — offline-first for people who are genuinely off-grid.
