It is not coincidence that campesino claim for land reactivates cyclically in such a way as to become one of the most recurrent and sensitive social and political phenomena of the transition in a country whose economy is sustained by agriculture, where half of the population still lives in rural areas and where the agrarian structure remains imbalanced. It also has serious ecological repercussions since demands are focused almost exclusively on forest plots of land considered as «idle» or not «rationally exploited», encouraging big landowners to rid themselves of forests in order to avoid expropriation.
