About us
The IEES was founded in 1993, with the idea to bring together experts and conduct Ecological Engineering activities within an international society
Our goals
IEES is a non-profit organization seeking to promote and advance a broad view of Ecological Engineering (working definition of IEES) through these four core activities:

Connect
Facilitate and improve the cooperation between ecologists, engineers and other scientific fields

Exchange
Promote the exchange between scientific and educational organizations, enterprises, and (non-)governmental organizations

Educate
Support the development of a common Ecological Engineering curriculum

Promote
Raise the awareness of Ecological Engineering practice worldwide

Our history
The idea to bring together experts and conduct Ecological Engineering activties within an international society was born at the 1st Conference on Ecological Engineering in Stensund, Sweden in 1991.
The Stensund Ecological Center with its ‘Vattenbruket’, a Wastewater Aquaculture greenhouse demonstrating Ecological Engineering principles of closed nutrient cycles served as a unique crystallization point.
Two years later, in October 1993 the society was officially founded in Utrecht, Netherlands by thirteen engaged participants. The first annual meeting was held in June 1994 in Stangvik, Norway. Since then the network has been spanning widely around the globe with its headquarter today located in Switzerland at ZHAW Wädenswil.
