Actress Eva Longoria headed to Guatemala on Wednesday (20Mar13) to discuss agriculture with local farmers as part of a charity mission.

The former Desperate Housewives star flew to the Central American country with philanthropist Howard G. Buffett.

The pair visited projects started up in 2008 by the World Food Programme with the aid of Buffett's own foundation, which aims to help poor farmers grow and develop their businesses.

The star took to her Twitter.com to post a series of snaps from her trip, during which she chatted to locals about the charity's new cacao initiative.

She writes, "Landed in Guatemala... learning about agriculture and its ties to immigration with World Food Programme and Howard Buffett! These r (are) some amazing farmers!... Did you guys know this is where cashews come from!! This beautiful fruit bears the nut on top! It's inside! Cool!"
