AgriTrace™ Master Thesis Proposal

A Blockchain-Enabled Traceability, Transparency, and Sustainability Platform for Agricultural and Agroforestry Supply Chains

CHAPTER 1: INTRODUCTION

1.1 Background of the Study

Agricultural and agroforestry supply chains are undergoing rapid transformation driven by increasing global demand for transparency, sustainability, and product authenticity. High-value commodities such as essential oils, timber, and specialty crops are particularly vulnerable to fraud, mislabeling, and lack of traceability. Traditional systems rely heavily on manual documentation, which is prone to errors, manipulation, and inefficiencies.

Emerging technologies such as blockchain, Internet of Things (IoT), and digital traceability systems offer a transformative solution. Blockchain provides an immutable and decentralized ledger that ensures data integrity, while QR codes enable real-time verification by end users. When integrated into a unified platform, these technologies can establish a transparent and trustworthy supply chain.

AgriTrace™ is proposed as a comprehensive platform that integrates blockchain verification, digital data capture, and QR-based authentication to ensure end-to-end traceability from farm to verified market.

1.2 Problem Statement

This study seeks to address the following problems:

  1. Lack of transparent and reliable traceability systems in agriculture
  2. Prevalence of fraud, substitution, and mislabeling of products
  3. Inefficient and fragmented compliance documentation processes
  4. Limited access of farmers to premium markets due to lack of verified data
  5. Absence of integrated digital platforms for sustainability and ESG reporting

1.3 Objectives of the Study

General Objective

To design, develop, and evaluate a blockchain-enabled traceability system (AgriTrace™) for agricultural supply chains.

Specific Objectives

  1. To design a digital system for plantation and origin registration
  2. To implement real-time field data capture mechanisms
  3. To develop batch tracking and processing modules
  4. To integrate blockchain-based verification of critical events
  5. To design a QR code-based authentication system
  6. To incorporate sustainability and carbon credit tracking features
  7. To evaluate the system in terms of usability, performance, and security

1.4 Significance of the Study

  • Farmers: improved documentation and access to premium markets
  • Exporters: enhanced compliance and traceability
  • Consumers: increased trust and product transparency
  • Researchers: contribution to blockchain applications in agriculture
  • Government: improved monitoring and regulatory compliance

1.5 Scope and Limitations

Scope

  • Development of a functional prototype system
  • Implementation of blockchain-based verification
  • QR code authentication
  • Sustainability tracking module (conceptual or simulated)

Limitations

  • Limited to pilot-scale implementation

CHAPTER 2: REVIEW OF RELATED LITERATURE AND STUDIES

2.1 Agricultural Traceability Systems

Traceability systems are essential for ensuring food safety and quality. However, existing systems often lack interoperability and real-time verification capabilities.

2.2 Blockchain Technology in Supply Chains

Blockchain technology enables decentralized, immutable recordkeeping. Studies show its effectiveness in improving transparency, reducing fraud, and enhancing trust.

2.3 QR Code-Based Authentication

QR codes provide a simple and effective interface for accessing product information and verifying authenticity.
