How Climate Change Affects Fruit Production

INTRODUCTION

GLOBAL: THE APPLE

Apples, one of the most common fruits in the world, according to a study that was published in PLoS One, a peer-reviewed journal, may become more expensive or not possible at all in some areas, due to rising winter temperatures. Evan Girvetz, a Nature Conservancy climate scientist and co-author of the study, says:

“…many fruit and nut trees, such as cherries, apples, apricots, walnuts, and almonds, require cold weather during the winter and early spring time to cue the trees to flower and produce good yields of fruits and nuts. These trees have evolved in areas that freeze, and they go dormant during the

How Climate Change Affects Fruit Production

INTRODUCTION

GLOBAL: THE APPLE

Apples, one of the most common fruits in the world, according to a study that was published in PLoS One, a peer-reviewed journal, may become more expensive or not possible at all in some areas, due to rising winter temperatures. Evan Girvetz, a Nature Conservancy climate scientist and co-author of the study, says:

“…many fruit and nut trees, such as cherries, apples, apricots, walnuts, and almonds, require cold weather during the winter and early spring time to cue the trees to flower and produce good yields of fruits and nuts. These trees have evolved in areas that freeze, and they go dormant during the winter to protect themselves from frost damage. In order to know when to come out of dormancy, they internally keep track of the amount of cold that has occurred over winter.”

He goes on to explain that once exposed to the chilling requirement, the amount of cold weather plants need to break dormancy, they will flower then bear fruit. The trees do not properly break dormancy when there is inadequate cold weather, and often can cause them to produce less and even completely fail in some years. A solution suggested in the paper for the fruit and nut trees of Central Valley, California, was migrating crops northward to areas like Oregon and Washington, but problems that this presents include:

- Soil/land difference: According to Girvetz,
