I am sorry to disappoint if you were expecting a graph related to the recent coup or the Tuareg occupation of the north. This is actually good news:
The graph shows the increase in agricultural production in south Mali. The performance is outstanding. Mali has gone from being "a food deficit country to a bread basket." According to a recent paper by Foltz, Aldana, and Laris (February 2012) the increase in production is due to the adoption of new seeds, but more importantly to the use of fertilizers. The graph is taken from the paper.
