Advancing Post-Harvest Management Systems via Energy-Efficient Solar Integration

The global agricultural sector faces a triple threat: a rapidly growing population, stagnant crop yields, and the unpredictable impact of climate change. One of the most effective yet under-utilized strategies to combat food insecurity is the optimization of post-harvest management.

By integrating renewable energy solutions, specifically solar-assisted cooling and drying technologies we can significantly reduce waste, stabilize food prices, and empower farmers economically while minimizing the environmental footprint of the food supply chain.

The Global Challenge of Food Security

An increase in population, limited agricultural yield, and adverse climatic conditions present a significant threat to food security, yet the subject is under-researched globally. Investing in agricultural post-harvest loss related to renewable energy and energy efficiency interventions is crucial to reducing post-harvest loss, global hunger, and farmer exploitation.

Innovative Solutions for Post-Harvest Loss

Although considerable work is reported on drying and cooling techniques to reduce post-harvest losses, the objective of this study is to discuss novel energy-efficient technology, including simultaneous cooling and drying options, so that it can reduce post-harvest losses.

Integration of Renewable Energy Systems

The various integrations of solar PV/T-assisted refrigeration systems, such as heat pump, vapor compression refrigeration systems, and vapor absorption refrigeration systems, are discussed here.

This integration aims to achieve a cost-effective, energy-efficient system for effective post-harvest loss reduction, reduce greenhouse gas emissions, double the farmers’ income, and reduce the price fluctuation of food commodities.

Future Trends and Sustainability

In recent years, the scientific community has shown a growing interest in post-harvest technology, primarily because of its potential to offer energy efficiency, affordability, off-grid capabilities, and self-sustainability.

The present study reviews various energy-efficient and renewable energy-integrated post-harvest techniques that are being explored today, including simultaneous cooling and drying techniques for the extended shelf life of agricultural produce.
