Previous research has shown horticultural therapy (HT) provides both physical and mental benefits to those engaged in the gardening activities. Individuals' willingness-to-pay (WTP) for these benefits, however, is unknown because of the lack of well-defined markets for HT. As such, this study estimates individuals' mean WTP for a HT site in Busan, South Korea. Mean WTP is ≈$170/month U.S. per individual. WTP, however, shows a wide dispersion; the standard deviation of the estimated WTP is ≈$60 U.S. This study provides additional information to the policymakers of Busan concerning the issue of developing a horticultural site for its citizens. This information must be weighed against the costs of developing the site.

The historical effects of El Niño/La Niña events on supplies of selected fresh vegetables and melons (Cucumis melo L.) were evaluated by estimating single-equation supply relationships. Economic variables in the estimated equations were, generally, of the correct sign and significant at usual levels. El Niño events had a negative and statistically significant effect on the Texas muskmelon, Florida fall squash [Praecitrullus fistulosus Stocks) Pang.] and the California fall lettuce (Lactuca sativa L.) supply with expected production declines of 15%, 21%, and 5% relative to historical mean production. In contrast, the expected supplies of United States summer onions (Allium cepa L.) and Florida fall and winter tomatoes (Lycopersicon esculentum Mill.) increased about 7%, 10%, and 25% during El Niño events. La Niña events had a negative and significant effect on Texas muskmelon, honeydew, and watermelon, with supplies expected to decline 20%, 29%, and 13% with the occurrence of this event.
