Technology

Strengths

Limitations

IoT15,40,41,42

Real-time monitoring and control, low-cost and energy-efficient sensor deployment, continuous data collection, High efficiency, and sensor network

Limited battery life for remote deployment, sensor calibration complexity, limited connectivity in rural areas, and security problems

UAV23,36,43

High resolution aerial imaging, large and inaccessible farmland coverage, and rapid data acquisition

susceptibility to weather condition, limited flight period, complex design, and data processing overhead

Blockchain44,45,46

Traceability, security, decentralized data acquisition and decision-making, and reliable supply chain

High computational resource demand, complexity for small-scale systems, not yet widely adopted for smallholder farmers

5G42,44,47

extremely low latency, fast data transmission for real-time analytics, and suitability for cloud computing

Limited coverage in rural/remote farming areas, advanced infrastructure requirements

AI/ML34,35,39,]

High detection and prediction accuracy, feature extraction from complex agriculturally based data, human like text generation for farmers

Requires large datasets, high computational cost, and black-box decision-making process, making difficult for farmers to interpret

IoT + UAV + ML23,48

Integrated smart farming with real-time imaging and edge intelligence, intelligent decision support to farmers, and precision interventions (e.g., targeted spraying)

System complexity, synchronization and interoperability challenges, energy consumption constraints, and require strong internet connectivity which may be limited for rural and remote farmlands
