Research on Ecological Monitoring of Digital Agriculture Industry Driven by Remote Sensing-Smart Devices-AI Collaboration

Summary

This protocol visualizes a remote sensing-AI-IoT integrated workflow for real-time ecological monitoring and decision support in digital agriculture.

Abstract

Continuous ecological monitoring is required for digital agriculture, but traditional approaches usually rely on isolated data sources such as satellites, UAVs, or field sensors, which limit spatial coverage, temporal frequency, and real-time decision-making. A single protocol that combines multi-scale data and describes how to create an effective and scalable monitoring workflow is desperately needed. To provide a dependable and automated ecological monitoring system for digital agriculture, this research aims to provide a clear, sequential process for combining remote sensing, smart field-based equipment, and Artificial Intelligence (AI) techniques. Developing an integrated monitoring method that provides reliable, high-resolution ecological data remains possible by adhering to the protocol. Harmonized datasets, robust data streams, and automated analytical outputs appropriate for operational agricultural monitoring are produced by the integrated Long Short-Term Memory with Transformer and Graph Neural Network (LSTM/Transformer/GCN) technique. Experiments were carried out in the Huang-Huai-Hai Plain (China) over a full crop rotation cycle (June 2023-May 2024). Results showed that fused data improved overall integrity to 92.3 ± 2.1% (23.5% higher than single RS data), reducing RMSE of soil volumetric water content (to 1.78 ± 0.25%) and crop NDVI (to 0.04 ± 0.01) by over 50%. Investigators and practitioners are able to utilize the structured methodology to implement real-time ecological monitoring in a useful and flexible way. It facilitates effective, automated, and scalable digital farming applications by integrating remote sensing, advanced technology, and AI applications.

Introduction

Digitization of agriculture has become a necessity in the world to solve the twofold crises of food security and conservation of agricultural systems. As the global population is expected to grow to 9.7 billion by the year 2050, agricultural output will have to increase by a substantial margin, yet conventional intensive agriculture has already caused devastating ecological effects, including soil salinization, loss of biodiversity, and water pollution, which has created a dilemma between productivity and ecological wellbeing¹. Here, the combination of remote sensing (RS), smart devices, and artificial intelligence (AI) may be regarded as a dis....

Results

Comparison of multi-source data fusion effects
To verify the value of integrating RS and IoT data for agricultural ecological monitoring, this section compares three data modes-single RS data, single IoT data, and fused RS-IoT data-from three perspectives: data integrity, estimation accuracy of key ecological indicators, and spatiotemporal coverage. All comparisons are based on 12 months of data (June 2023-May 2024) from the Huang-Huai-Hai Plain experimental area, with statistical significance tested.......

Discussion

This research offers a collaborative remote sensing-smart devices-AI architecture that aims to address the typical fragmentation of digital agricultural ecological monitoring.
