In Easter Island history, agriculture played a vital economic role, be it out of the basic need to feed the population or, in a more advanced stage, to produce surplus food (Stevenson and Haoa 1999, Stevenson et al. 1999). Stevenson et al. (1999) state that agricultural production on Easter Island was generated by dryland agricultural systems, albeit designed to reduce agricultural risk.
