At Loudi Agricultural Development Limited, we're a small Chinese agricultural company working on high-yield rice localization in Rwanda. Our team is based between Loudi (Hunan, China) and Kigali, Rwanda, and we've been working on adaptive seed breeding across multiple agro-ecological zones in the country.
The Problem
Rwanda imports a significant portion of its rice. Local farmers and extension workers often lack access to up-to-date agronomic guidance — what varieties to plant, when to plant them, how to manage common diseases like rice blast, and what post-harvest practices to follow. The information exists in scattered government documents, research papers, and RAB (Rwanda Agriculture Board) publications, but it's not easily accessible in the field.
What We Built
We created Ask Loudi — a free, multilingual AI agricultural assistant that answers questions about rice farming in Rwanda. It supports English, Chinese, and Kinyarwanda.
The architecture is straightforward:
- Knowledge base: 90+ curated documents covering Rwanda's rice sector — national rice development strategies, RAB technical guidelines, pest and disease management, variety performance data, and post-harvest processing standards
- RAG pipeline: We use a self-hosted FastGPT instance on a Singapore VPS, connected to a vector database for retrieval-augmented generation
- LLM: Google Gemini API for inference
- Frontend: A lightweight HTML/CSS/JS chat interface deployed on Cloudflare Pages
- API layer: Cloudflare Workers as middleware between the frontend and FastGPT backend
- TTS: Edge-TTS integration for voice output, important for users with lower literacy levels
The bot is available at ask.loudiagri.com and we're working on WhatsApp integration for farmers who primarily use mobile.
Why RAG, Not Fine-Tuning
Agricultural advice has real consequences. If the AI hallucinates and recommends the wrong fertilizer dosage or misidentifies a disease, it can damage an entire season's crop. RAG lets us ground every answer in verified local data. The knowledge base is curated from official Rwandan government sources, so we can trace every recommendation back to its origin.
The Bigger Picture
Loudi Agri has been operating since 2018, starting with farmland construction projects in Hunan Province. In 2024 we expanded to Rwanda, completing our ODI (Outbound Direct Investment) filing with China's Ministry of Commerce. Our core team — including a chief agronomist with decades of experience in African agriculture — deployed to Rwanda in early 2026.
Our Rwanda program follows a "One Hub, Three Zones" model:
- Kigali: Coordination hub
- Muhanga District: Demonstration zone, linked to the Loudi–Muhanga sister-city framework
- Kayonza: Seed breeding pilot site
- Eastern Province (Nyagatare/Muvumba): Planned large-scale production zone
The AI assistant is one piece of a larger effort to bring Chinese agricultural expertise to East Africa in a way that actually works on the ground — not just technology transfer, but genuine localization.
