In reality, the term is applied quite liberally and almost invariably falls short of environmentalist ideals of being completely self-sustaining. The Sustainable Winegrowing New Zealand (SWNZ) initiative, for example, was established in 1995 to provide a ‘best practice’ environmental model for both vineyard and winery. SWNZ is independently audited but stops short of prohibiting man-made inputs such as pesticides. However, such programmes can, via grower education, significantly reduce the number and strength of chemical sprayings, which is of both environmental and economic benefit. A related approach is integrated pest management, as are LISA or LEISA, acronyms which stand for Low (External) Input Sustainable Agriculture, terms often used for programmes in North America and Australia.
