Wheat, a vital cereal crop, faces significant quantitative and qualitative losses due to factors such as pests, diseases, inefficient agricultural practices, inadequate storage, and environmental challenges. In developing countries, losses are predominantly concentrated at the farm level due to limited access to modern technologies and infrastructure, while developed countries experience higher losses during the consumption phase. The review highlights the importance of<br />adopting advanced technologies and sustainable practices to reduce losses. Mechanized harvesting, when properly calibrated, can minimize grain shedding and breakage, while modern storage solutions like expanded metal silos and controlled-environment systems can prevent spoilage and pest infestations. Solar-powered drying methods and biodegradable packaging materials offer environmentally friendly alternatives to traditional practices. Pre-harvest interventions, such as cultivating high-yielding and pestresistant seed varieties, optimizing planting practices, and improving soil health, are also critical for reducing losses at the source. Furthermore, the review emphasizes the need for integrated approaches, including farmer education, policy support, and cross-sector collaboration, to address wheat losses effectively. By implementing evidence-based solutions tailored to local contexts, stakeholders can enhance food availability, reduce economic pressures, and promote environmental sustainability. This review serves as a roadmap for minimizing wheat losses, ensuring a resilient and efficient supply chain, and contributing to global food security for future generations. https://best.basu.ac.ir/article_6275_22c432f46fd86e1be5bc4429282eb65d.pdf
