Fig. 9. The relationship between the change in total forest cover and gross agricultural income per hectare in 2000 for 57 districts in Panama. The change in total forest cover is expressed as the ratio of forest area in 2000 to that in 1992. Brown downward-pointing triangles indicate districts that were largely deforested before 1947; green upward-pointing triangles indicate districts that were largely forested in 1947.
