Imported appies of the same cultivar wem grown in a Southern hemisphere winter in Nelson, Southland, New Zealand, and were picked at the end of March with subsequent 28 d transport by sea for sale in April in Germany. Locally-grown apples (cultivar 'Braeburn') were picked in mid-October and required a primary energy of nearly 6 MJ/kg of fruit including 0.8 MJoule/kg for five months CA storage at 1 degree C during a Northern hemisphere winter until mid-March. This compared favourably with 7,5 MJoule/kg for overseas shipment from New Zealand, i.e. a ca. 27 percent greater energy requirement for these imported fruits. Overall, the primary energy requirement of regional produce, stored several months an-site, partially compensated for the larger energy required to Import fresh fruit from overseas. This result is in marked contrast to reported overestimares of a reported up to 8-fold energy requirement for domestic versus imported apple juice concentrate. Our own findings of km primary energy required for domestic apple fruit is discussed with respect to providing local employment, fruit orchards preserving the countryside, quality assurance systems for local fruit such as QS and EUREP-GAP, networking and other factors favouring regional production.
