The assessment is based on primary and secondary data collection. Price data was obtained from the Gambian Ministry of Trade and the Gambian Bureau of Statistics as well as selected local markets.
Primary data was collected on several markets through focus group discussions and interviews with traders. Data collection tools included a market questionnaire, a trader questionnaire and an interview guide for discussions with importers. Markets were selected based on the number of people that use these markets as their primary source of staple food, essentially urban and peri-urban markets.
