IMPLICATIONS FOR WORLD TRADE FROM THE CANCELLATION OF METHYL BROMIDE

During the next seven years, all agricultural uses of methyl bromide (MBr) are due to be phased out in compliance with mandates from the United Nations Environment Program. This paper will address the implications of this phase out with respect to the world walnut industry and will specifically use California as an example. Since California is the world's leading exporter of walnuts (followed by China) the consequences of an MBr cancellation will fall heavily on it with trading implications for other countries as well.

MBr is used in two ways: as a soil fumigant, and as a postharvest treatment for shipments into distribution channels. In assessing the economic impacts of the loss or restriction of MBr, it is necessary to analyze the alternatives that are available. In the case of MBr, few alternatives are available with two consequences. The first is an increase in the cost of treatment. The second is a market impact from the inability to deliver new-crop walnuts on a timely basis to export markets. These two impacts will be discussed and then related to implications for world trade in walnuts. In addition, a long run scenario will be evaluated to determine possible alternatives that might be considered to mitigate the impacts of MBr loss.
