Here, examples are drawn from researchon New Zea­land caves and examined in the context of sustainable cave use management practices. The work considers that the cave man­ager is concerned, firstly, withdefining the desired or optimal level or range of environmental conditions that should prevail and, secondly, withmaintaining them. To do this requires an appropriate and reliable monitoring system. It involves select­ing key indicators to be monitored and setting target standards. Selection of an appropriate monitoring system, however, re­lies on having a good understanding of the climate processes operating, essentially how they work and how they might be appropriately managed. Unlike microclimates in the atmo­sphere-land boundary layer, whichare characterized by verti­cal exchanges, processes determining climate in all but nearly closed caves are dominated by advection of heat and moisture. It is this process that may give rise to distinct spatial and tem­poral patterns of climates in caves. Thermoadynamic aspects of external air-cave air interaction are assessed to explain spatial as well as short term and seasonal variations of thermal and moisture states of the cave atmosphere. The relevance of all this to cave management is discussed. It is argued that cave man­agement is not simply a matter of determining usage levels or carrying capacity of caves; rather, it involves determining en­vironmental management techniques that are appropriate to a particular cave condition or environmental state that should prevail.</span></p>}, number={3}, journal={Acta Carsologica}, author={de Freitas, Chris R.}, year={2010}, month={Dec.} }
