Ecological Engineering
Ecological Engineering
This term was first defined by H.T. Odum in 1962 as ‘environmental manipulation by man using small amounts of supplementary energy to control systems in which the main energy drives are still coming from natural sources’. This was because although the energy supplied by man is small relative to natural sources it can be sufficient to produce large effects. Hence there was a perceived need to provide more ecologically sound methods of environmental management so that in China since 1978 the term ‘ecological engineering’ has been used. Ecological engineering employs biological species, communities, ecosystems together with self-design through ecotechnology to achieve a more sustainable and less harsh management solution. It employs natural energy sources and self-regulating processes to design, construct, operate and ...
