The test identified a break in total wheat imports and per capita wheat imports in 1997 and 1996, respectively, while 2001 and 2002 emerge as the most significant break-years for total rice imports and per capita rice imports, respectively. These years correspond to significant policy shifts in Senegal, starting with the devaluation of the local currency (the CFA Franc) in 1994. Policy measures adopted included a full liberalisation of import in 1996 (rice trade was highly regulated by the State and imports were subject to quotas until 1996) and the implementation of the regional Common Exterior Thriff (CET) in 2000, leading to a drop in rice import tariff from 38% to 10%.
