Sustainable Biochar Production from Date Palms: A Scoping Review of Solutions for Arab Regions

Abstract

This scoping review investigates the potential of date palm biochar for sustainable agriculture in Arab nations. Analysis reveals that the 82.35 million date palm trees across 18 Arab countries could yield 576,423 tons of biochar annually, offering a significant resource for improving soil sustainability. This study systematically examines existing literature on date palm biochar production, its impact on soil health (including water and nutrient conservation), optimal application methods, and its potential to enhance food security in arid regions. The findings highlight the economic and environmental benefits of biochar, particularly for small-scale farmers, and discuss the Kuwait Biochar Initiative as a successful model for wider adoption of this sustainable agricultural practice. The review concludes by emphasizing the global potential of date palm biochar for sustainable agriculture and soil health.
