International Council of Scientific Unions (ICSU)Scientific Committee on Problems of the Environment (SCOPE)
SCOPE is one of a number of committees established by the nongovern-mental group of scientific organizations, the International Council of Sci-entific Unions (lCSU). The membership of ICSU includes representativesfrom 68 National Academies of Science, 18 International Unions and 12other bodies called Scientific Associates. To cover multidisciplinary activi-ties which include the interests of several unions, ICSU has established 10Scientific Committees, of which SCOPE is one. Currently representatives of34 member countries and 15 Unions and Scientific Committees participatein the work of SCOPE, which directs particular attention to the needs ofdeveloping countries. SCOPE was established in 1969 in response to theenvironmental concerns emerging at that time: ICSU recognized that manyof these concerns required scientific inputs spanning several disciplines andICSU Unions. SCOPE's first task was to prepare a report on Global Envi-ronmental Monitoring (SCOPE 1, 1971) for the UN Stockholm Conferenceon the Human Environment.
The mandate of SCOPE is to assemble, review, and assess the informa-tion available on man-made environmental changes and the effects of thesechanges on man; to assess and evaluate the methodologies of measurementof environmental parameters; to provide an intelligence service on currentresearch; and by the recruitment of the best available scientific informationand constructive thinking to establish itself as a corpus of informed advicefor the benefit of centres of fundamental research and of organizations andagencies operationally engaged in studies of the environment.
SCOPE is governed by a General Assembly, which meets every threeyears. Between such meetings its activities are directed by the ExecutiveCommittee.
