Life Sciences and Space Research XXIII(3): Natural and Artificial Ecosystems : Proceedings of the Topical Meeting of the COSPAR Interdisciplinary Scientific Commission F (Meetings F9, F10, F11 and F12) of the COSPAR Twenty-seventh Plenary Meeting Held in Espoo, Finland, 18-29 July 1988The papers presented at these Topical Meetings addressed research issues concerned with the growth of plants and the recycling of wastes within artificial ecosystems such as Controlled Ecological Life Support Systems (CELSS), the development of bioreactors for use in space and carbon cycling in natural ecosystems. It is anticipated that a better understanding of the dynamics and mechanisms of the natural ecosystems of the Earth, in which human activities play an increasingly important role, will provide significant information to support the development of artificial ecosystems for life support. In turn, it is expected that in developing ecosystems for the specific purpose of supporting humans in space, a better understanding of natural ecosystems will emerge. |
