Standardization process of the FBS:Examples of various commodities
James Geehan,Statistician, FAO Rome
Recap: Standardization
• A typical Supply Utilization Account can contain information for up to 1,500 commodities.
• While this is useful for a comprehensive picture of the a country’s food supply, the amount of data is unmanageable and difficult for practitioners and policy makers to analyse.
• The solution is to reduce the list of commodities captured within the SUA to a shorter, standardized, commodity list and presented in Food Balance Sheet format.
• Standardization is the process of converting original quantities in the SUA back into their primary commodity equivalent
• For example, flour of wheat back into the equivalent wheat quantity; or skimmed cow milk back into the equivalent whole cow milk quantity.
Supply Utilization Accounts
(1,500+ commodities)
Standardization ofcommodities
Food Balance Sheets(Approx. 100 primary commodities)
Standardization example – 3 commodity groups: Wheat, Other Cereals, and Milk
Step 1:• Reduce the list to the originating commodities. Sum the calorie and nutrient values of derived and origin commodities.
Standardization example – Wheat, Other Cereals, and Milk
Step 2: The Input to derived commodities are subtracted from Processing in the origin commodity. Production of derived commodities is not converted back, to avoid double counting.
Standardization example – Wheat, Other Cereals, and Milk
Step 3: For all other SUA elements in derived commodities, quantities are converted back to their origin commodity using the reciprocal of the extraction rate.
Standardization example – Wheat, Other Cereals, and Milk
Step 3:• For all other SUA elements in derived commodities, quantities are converted back to their origin commodity using the reciprocal of the extraction rate.
Standardization example – Wheat, Other Cereals, and Milk
Example: Imports of Flour of Wheat soft back to Wheat soft
Extr. rate of Wheat soft to Flour of Wheat soft = 80%Reciprocal = 1 / 0.8 = 1.25
Imports of Flour of wheat soft = 45 * 1.25 = 56Imports of Wheat soft = 400
Total import of Wheat soft (including derived commodities) = 456
Step 3:• For all other SUA elements in derived commodities, quantities are converted back to their origin commodity using the reciprocal of the extraction rate.
Standardization example – Wheat, Other Cereals, and Milk
Example: Imports of Flour of Wheat soft back to Wheat soft
Extr. rate of Wheat soft to Flour of Wheat soft = 80%Reciprocal = 1 / 0.8 = 1.25
Imports of Flour of wheat soft = 45 * 1.25 = 56Imports of Wheat soft = 400
Total import of Wheat soft (including derived commodities) = 456
Step 3:• For all other SUA elements in derived commodities, quantities are converted back to their origin commodity using the reciprocal of the extraction rate.
Standardization example – Wheat, Other Cereals, and Milk
Example: Feed of Skimmed cow milk back to Cow milk whole
Extr. rate of Cow milk whole to Skimmed cow milk = 96%Reciprocal = 1 / 0.96 = 1.04
Feed of Skimmed cow milk = 36 * 1.04 = 38Feed of Cow milk whole = 0
Total Feed of Cow milk (including derived commodities) = 38
Step 3:• For all other SUA elements in derived commodities, quantities are converted back to their origin commodity using the reciprocal of the extraction rate.
Standardization example – Wheat, Other Cereals, and Milk
Example: Feed of Skimmed cow milk back to Cow milk whole
Extr. rate of Cow milk whole to Skimmed cow milk = 96%Reciprocal = 1 / 0.96 = 1.04
Feed of Skimmed cow milk = 36 * 1.04 = 38Feed of Cow milk whole = 0
Total Feed of Cow milk (including derived commodities) = 38
Step 3:• For all other SUA elements in derived commodities, quantities are converted back to their origin commodity using the reciprocal of the extraction rate.
Standardization example – Wheat, Other Cereals, and Milk
Example: Imports of Flour of Other cereals back to Other cereals
Extr. rate of Other cereals to Flour of Other cereals = 80%Reciprocal = 1 / 0.80 = 1.25
Imports of Flour of other cereals = 35 * 1.25 = 44Imports of Other cereals = 0
Total import of Other cereals (including derived commodities) = 44
