Ecotechnology 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.
Ecotechnology emphasizes approaching a problem from a holistic point of view. For example, remediation of rivers should not only consider one single area. Rather, the whole catchment area, which includes the upstream, middle stream and downstream sections, should be considered.
Construction can reduce its impact on nature by consulting experts on the environment.
Sustainable development requires the implementation of environmentally friendly technologies which are both efficient and adapted to local conditions. Ecotechnology allows improvement in economic performance while minimizing harm to the environment by:
During Ecotechnics '95 - International Symposium on Ecological Engineering in Östersund, Sweden, the participants agreed on the definition: "Ecotechnics is defined as the method of designing future societies within ecological frames."
