title: Material flow estimation in CELSS.
abstract: Through the tentative lunar base construction study aiming to explore the system design method regarding closed loop life support system, the feasible system configuration including many subsystems is defined.  Based upon this configuration and the estimated metabolic data of human and plants, the required material flow quantities between each subsystem in order to keep the appropriate condition for human and plants have been estimated.  For promoting such fundamental researches on these subsystems and for planning the installation of test beds to check the closed loop life support function, new institute, Institute for Environmental Sciences, has been established in the end of last year.
