In the current times, the old-fashioned Reductionism has given space to the other approach to study the world and surroundings, the Holism or Systemic view. Inside this holistic approach, the disciplines start to loose their rigid boundaries and begin to produce the sciences of the new millennium: the multidisciplinary sciences, the interdisciplinary sciences and the transdisciplinary sciences.
The multidisciplinary sciences are sciences that in their research involve the inclusion of more than two different sciences or disciplines. The interdisciplinary sciences, on the other side, are new fields that are produced by the interaction of different disciplines. Finally transdisciplinary sciences are new disciplines that are transverse to a number of different classic (well defined) disciplines.
In this site, the interest is in the "environmental problems"-related fields of study and [Environmental] Sustainable [Economic] Development . Therefore, in this site you can not find information about other types of multidisciplinary sciences.
