Wind constraints to agricultural productivity
Although wind is the dominant component of 'exposure', its effects are often reinforced by the additional effects of rain and extreme air temperatures and, in coastal areas, by the salt it carries. Some physical and biological effects of exposure on soil erosion, plant and animal productivities, and fuel use in horticultural glasshouse operation are briefly considered in the New Zealand context. An attempt is made to assess some of the economic effects of exposure while recognising the difficulties of measurement. Finally, areas which need further research are outlined.
