The majority of this study comes from primary data collected via questionnaires, as well as site visits to the pineapple and banana farms and their respective packing facilities in Costa Rica and Honduras. All site visits took place in November 2010.
The water footprint of bananas and pineapples is the sum of the water footprints for all processes in the supply chain, which consists of first growing and then handling the crops. In other words, total water footprint = water footprint of farm phase + water footprint of packing facility phase.
Green and Blue Water Footprints
The blue and the green water footprints present evapotranspiratation loss of water. These footprints are calculated as crop water use per crop yields.
