This report evaluates the Bank Group’s assistance to Mauritania by focusing on the 1994-2004 period. Its preparation was done in two stages: the sector evaluations provided the basis for the overall evaluation at country level, which completed and validated preliminary results of sector reviews. Two sector reviews were prepared on agriculture and rural development and on the social sectors as well as internal notes on the other sectors. The report was restructured following the preparation of new Guidelines for Country Assistance Evaluation at the end of 2004. The timetable for the finalisation of this report took into account its objective to draw lessons and make useful recommendations for the next Country Strategy Paper cycle (CSP).
