Day labourer Jorge Ibanez, 20, helps load a sack filled with potatoes onto a truck as he harvests potatoes in the southern Spanish region of Cartagena, Murcia, June 7, 2013. Ibanez quit school at the age of 16 to help pay the bills at home and did various different jobs before going back to complete his secondary education. Recently, he decided to start working as a day labourer. "I know for sure this is not what I want to do for the rest of my life, but this is all I can find now," he says. The majority of day labourers in the region come from Morocco and Ecuador, and it can be rare to see Spanish labourers in the fields. Nevertheless, as Spain wrestles with economic crisis and youth unemployment levels above 50 percent, some young Spaniards are starting to consider the kinds of jobs mostly performed by immigrants during the boom years.

Spanish farmer Santiago Perez watches as 'rebuscadores' (gleaners) prepare to leave with a sack of potatoes they collected from one of his harvested fields in the southern Spanish region of Murcia June 5, 2013. Gleaning, or gathering leftover produce after a harvest, is a traditional practice in rural areas, but has become more common since the economic crisis hit. "As long as they do it once we have harvested, we don't care. The discarded produce is fit to eat, it just didn't meet our standards for our clients" Perez explains.
