Since at least the 1960’s there has been a growing awareness that the whole of the human environment (its society and supporting ecosystems as well as its economy) needs to be better included in decision making. This awareness has not been restricted to a single discipline but has emerged in the fields of Land use planning, in Science, in Economics, and in Accounting. Each of these differing approaches has developed its own language and discipline such as Sustainable Development and Ecologically Sustainable Development, Ecological Economics, Environmental Accounting, Ecological Footprints and Services and Social Cost-Benefit Analysis.
