The Global Environment Monitoring System (GEMS) is a collective effort of the world community to acquire, through monitoring, the data needed for rational management of the environment, and arose from recommendations of the United Nations Conference on the Human Environment which was held in Stockholm in 1972. The GEMS Programme Activity Centre (PAC) at UNEP headquarters in Nairobi, Kenya, coordinates all that it can of the various environmental monitoring activities which are carried on throughout the world—particularly those within the United Nations System.

Great care is taken to ensure that data gathered by GEMS are of the highest attainable quality, and that data collected from different parts of a particular monitoring network are both comparable and compatible. The GEMS Programme Activity Centre (PAC), in the manner of UNEP itself, is not operational but works mainly through the intermediary of the Specialized Agencies of the United Nations System—most notably FAO, ILO, UNESCO, WHO, and WMO—together with appropriate intergovernmental organizations such as IUCN.

The GEMS monitoring system consists of five closelyinterrelated programmes which have built-in provision for training and for rendering technical assistance to ensure the participation of countries that are inadequately provided with personnel and equipment. The five are:

1. Climate-related monitoring;

2. Monitoring of long-range transport of pollutants;

3. Health-related monitoring (concerned with pollutional effects);

4. Ocean monitoring; and

5. Terrestrial renewable-resource monitoring.

Each of these broad areas contains at least five distinct world-wide monitoring networks. Examples of these latter are the World Glacier Inventory, Background Air Pollution Monitoring Network, Urban Air Pollution Monitoring Network, Global Water Quality Monitoring Network, Tropical Forest Monitoring Network, Species Conservation Monitoring Network, etc.

Monitored data are gathered at suitable coordinating centres for each network at which appropriate data-bases have been, or are being, established. Data are analyzed to produce periodic regional and global assessments which are reported at intervals that are appropriate to the variable which is being considered.

After a requested account of how, starting from his student days, he had come gradually to ‘care about our Only One Biosphere’ and think globally (even if commonly acting only locally), the Author presents his ‘thoughts on what might best be done to [foster a World Campaign for the Biosphere] and make it operationally effective’. This Campaign should be world-wide and have the objective of educating everybody everywhere to full realization of the following facts and their often imperatively grave implications: (1) The Biosphere constitutes a single integrated whole of which all parts are often intricately interdependent, (2) we humans form an integral part of the Biosphere but are becoming far too numerous and heavily dominant for its or our own good, (3) we are absolutely dependent on the health of the Biosphere for our own subsistence and more as it constitutes our sole life-support, (4) The Biosphere in part or even in toto is in several ways fragile, but (5) it is gravely threatened by various human activities and out-sized capabilities such as those of nuclear weaponry which are said to be sufficient to destroy our civilization several times over, and conceivably even the entire Biosphere.

The second, longer part of the article is devoted to consideration of the following chosen ‘round dozen’ recommended activities through which it is thought the Campaign might best be advanced, at least in its early stages: (1) Publishing and broadcasting pertinent information and support by all appropriate means; (2) Using other vehicles of desirable publicity, including posters and stickers; (3) Instructive advertising and audienceattracting showmanship; (4) Books on the Biosphere and illustrated study manuals; (5) Specialist research and its vigorous application; (6) Need to control human numbers and behaviour; (7) National Parks, Biosphere Reserves, and Biological Gardens, etc.; (8) Pertinent conferences, meetings, and other ‘free’ deliberations; (9) Need to change human attitudes and priorities; (10) Need to establish due ethics and laws; (11) Institutional and organizational involvement towards survival; and (12) ‘Guardians of the Biosphere’ recognition and awards.

The above 12 points largely follow those presaged in the Editorial in our preceding issue, since completion of which it has emerged that this Campaign should be socalled (without reference to any time-scale), and that it might best be furthered by two United Nations agencies, an intergovernmental one, and at least one nongovernmental one—all hopefully working in concert.
