Reasons why the supply of an agricultural commodity may be low even when the demand for it is high. 

• Bulkiness of the products making it difficult to transport to places where they are demanded
• Lack of method of preservation to sell in time of scarcity
• Poor transport system that fails transportation of agricultural products
• Long biological lag makes it difficult to increase supply in short run
• Weather uncertainties disrupting production
• Use of poor technology leading to low production
• Low production due to few farmers
• Seasonality making them to be in excess in certain part of the year and in short supply in the other part of the year e.g. grasshoppers (ensenene)
• Lack of storage facilities store excess
• Lack of inputs such as land
