Project Case Study
AgroGuard
Crop Issue Reporting & Expert Advisory Support Platform
AgroGuard helps farmers document crop issues with photos, location, farm context, and crop records, then connects those reports to admins and verified experts for structured advisory support.
Problem
- Farmers often report crop issues informally through phone calls or WhatsApp messages.
- Important details like photos, farm context, crop records, location, and timeline are easily lost in informal channels.
- Experts and admins need structured, consistent data to review and track cases properly.
- Without a system of record, there is no way to follow up, assign, or track the full lifecycle of a crop issue.
Solution
AgroGuard turns informal crop complaints into structured, trackable advisory workflows. The platform connects farmers, admins, and verified experts in a single report lifecycle:
