In the last decade, Jatropha curcas L. has obtained more and more attention as feedstock for biofuel production. However, the harvesting of this plant presents several problems, because fruits are in bunches and do not ripen simultaneously, and the mechanical solutions that allow to facilitate harvesting are still limited. Some mechanical and semi-mechanical harvesting methods have been developed worldwide with the purpose to optimize the harvesting process, reducing harvesting costs, and make this crop competitive with the other energy crops. The harvesting of Jatropha curcas L. remains a big constrains for the spread of the species as energy crop, and this work aims at presenting an overview of the harvesting methods for jatropha (manual picking, semi-mechanical harvesting, and full-mechanized harvesting), showing the pros and cons of each system, and highlighting the criteria to be considered for choosing one respect another. The second focus of this paper is the logistic of the jatropha harvesting, which has been described and schematized for each harvesting method identified.
