Sustainable development is a pattern of economic growth in which resource use aims to meet human needs while preserving the environment so that these needs can be met not only in the present, but also for generations to come (sometimes taught as ELF-Environment, Local people, Future.

According to different sources, the concept of sustainability in the sense of a balance between resource consumption and reproduction was however applied to forestry already in the 12th to 16th century.[21]

This had been the doctrine and, indeed, the ‘holy grail’ of foresters all over the world for more or less two centuries. The essence of ‘sustained yield forestry’ was described for example by William A. Duerr, a leading American expert on forestry: “To fulfill our obligations to our descendents and to stabilize our communities, each generation should sustain its resources at a high level and hand them along undiminished. The sustained yield of timber is an aspect of man’s most fundamental
