Valorization of palm residues coupled with solar desalination for oasis agriculture in Al-Ahsa

A novel approach combining palm residue valorization with solar desalination significantly enhances water reliability for oasis agriculture in Al-Ahsa, Saudi Arabia. The study identifies photovoltaic-thermal powered reverse osmosis as the most efficient method, maximizing freshwater yield and minimizing costs while maintaining water quality suitable for perennial crops. Hybrid forward osmosis with evaporation offers a balanced solution, while enhanced solar distillation is optimal for low-maintenance settings. By leveraging palm residues as absorbents or fuel inputs, this portfolio approach reduces reliance on fossil fuels and improves irrigation scheduling, contributing to sustainable oasis management.
