SHELTERBELTS AND KIWIFRUIT PRODUCTION

Mechanisms whereby shelterbelts effect kiwifruit production are briefly reviewed.
Adverse effects associated with proximity to natural shelterbelts, and the loss of productive land which they occupy, are quantified as a function of shelterbelt height.
Climatic enhancements through intensive sheltering are summarized and the wind flow and turbulence patterns for various common shelterbelt configurations described.
An examination of the wind field between repeated shelterbelts highlights differences in the sheltered zones for turbulence and mean windspeed.

Despite their widespread use, there exist no criteria for assessing shelterbelt effectiveness or design.
Here we outline a framework for assessing these factors in terms of risk management from which the wind/turbulence parameters and thresholds at which damage commences, emerge as key parameters to be determined.
