Sahil-memane/nexHarvest

A fully modular, production-ready Flask MVC backend backed by MongoDB Atlas. This project implements role-based access control, JWT session management, and a clean API surface for multiple dashboard types (Farmer, Insurance Officer, Admin). # 🌾 nexHarvest > **Farmer-Centric Dual-Hazard Crop Intelligence System** > Built for the **ClimateX 2026 + NABARD National Climate Stack Innovation Challenge** > Institution: JSPM Rajarshi Shahu College of Engineering, Pune --- ## 📌 Overview **ClimateForeSight** is a full-stack climate intelligence platform that combines real-time satellite data, machine learning, and automated insurance triggering to protect Indian farmers against drought and flood. The system provides a personalised Farmer Vulnerability Index (FVI), 15-year crop risk projections (2025–2040), and autonomous PMFBY insurance activation — all without manual paperwork. The platform serves **four distinct user roles** — Farmer, Loan Officer (NABARD), Insurance Officer, and Admin — each with their own dashboard view and access scope. --- ## 🗂️ Project Structure ``` nexHarvest/ ├── backend/ # Python Flask MVC Backend (REST API) │ ├── app.py # App factory, blueprint registration, JWT config │ ├── config.py # Environment variables (MongoDB URIs, JWT secret) │ ├── extensions.py # Flask-JWT-Extended + Flask-CORS globals │ ├── utils.py # @role_required RBAC decorator │ ├── requirements.txt # Python dependencies │ ├── db_seed.py # Database seeding utility │ ├── test_db.py # MongoDB connection test script │ │ │ ├── models/ # Data Access Objects (MongoDB Atlas) │ │ ├── db.py # Atlas connection + auto-index provisioning │ │ ├── user_model.py # Auth DB: User credentials & role mapping │ │ ├── session_model.py # Auth DB: JWT session tracking + TTL expiry │ │ ├── farmer_model.py # App DB: Farmer profile schema │ │ └── claim_model.py # App DB: Insurance claim tracking │ │ │ ├── controllers/ # Business Logic Layer │ │ ├── auth_controller.py …
