Abstract
Within the "Health and Environmenl" framework, a group of scientists in disciplinary fields as diverse as biology, medical sciences, model/ing, ecology, geography, computer sciences, are co/laborating to study the dynamics of infectious diseases in Southeast Asia. ln this paper they propose Io pool their knowledge on biological pathogens, environment and societies and to shore their field. laboratory and clinical expertise to address questions on research, disease monitoring and health management. An integrative plotform has been suggested and organised in order to implement a Scientific Observatory (OSAGE-S}, dedicated to supporting Health Management in a Territory. The first part of this work addresses generic and epistemological questions, formai/y explicits the formula "Health and Environment" in order to relate if to concepts such as "pathological system", "environment" and "observatory "; the second part relates to further operational issues for the observatory concept dedicated to the support of Health management. Thereafter we illustrate our proposition with a case study, the Chikungunya disease in lndonesia.
