Ecotechnology – not to be confused with ecotechnics – is an applied science that seeks to fulfill human needs while causing minimal ecological disruption, by harnessing and manipulating natural forces to leverage their beneficial effects. Ecotechnology integrates two fields of study: the 'ecology of technics' and the 'technics of ecology,' requiring an understanding of the structures and processes of ecosystems and societies. All sustainable engineering that can reduce damage to ecosystems, adopt ecology as a fundamental basis, and ensure conservation of biodiversity and sustainable development may be considered as forms of ecotechnology.
