Data Quality Indicators

Reliability 2 Verified data partly based on assumptions or non-verified data based on measurements
Completeness 1 Representative data from a sufficient sample of sites over an adequate period to even out normal fluctuations
Temporal correlation 1 Time period is equal to the period of study
Geographical correlation 1 Data from area under study
Access 1 Publicly and readily available data
Frequency 1 New data collected on an annual basis
Informality and illegality 5 Illegal or informal flows estimated at more than 30% or impossible to quantify
Classification compatibility 2 Data classified using a different yet compatible classification system

Imports & Exports

Food supply

Calculation made by replicating the methodology presented in this paper: https://www.tandfonline.com/doi/epdf/10.1080/23754931.2021.2006758?needAccess=true but updated for 2018.

Data Quality Indicators

Reliability 2 Verified data partly based on assumptions or non-verified data based on measurements
Completeness 1 Representative data from a sufficient sample of sites over an adequate period to even out normal fluctuations
Temporal correlation 2 Up to one year of difference to year of study
Geographical correlation 2 Average date from larger area in which the area under study is included and with which it shares comparable conditions.
Access 1 Publicly and readily available data
Frequency 5 No scheduled data collection interval
Informality and illegality 2 Illegal or informal flows estimated at no more than 5%
Classification compatibility 1 Data classification is identical to the chosen classification system

Food loss and waste

calculation based on combining Gato et al's 2024 database (total food loss by stage of the food system in tons) and FAOSTAT food supply data for 2014.
