Starting with my participation in the United Nations Conference on the Human Environment (Stockholm 1972) and joining the South Pacific Commission in 1974, I have worked with or been employed by international organizations, including the UN and its agencies, regional intergovernmental organizations and international non-governmental organizations, for most of my career. I organized the South Pacific Regional Environment Programme (SPREP) and helped to oversee many other Regional Seas Programmes. I have been responsible for intergovernmental meetings, including at the ministerial level, served in the secretariat for the UN Conference on Environment and Development (the Rio Earth Summit), acted as task manager for the Commission on Sustainable Development for 8 years, and provided the secretariat for a plenipotentiary meeting to adopt a convention. For a decade I was responsible for coordinating environmental monitoring and assessment across the whole UN system, including organizing the Sponsors Group for the Global Observing Systems and the Integrated Global Observing Strategy Partnership. This varied experience has given me unique perspectives on international environmental governance. Now I coordinate and teach in the UNEP/University of Geneva/Graduate Institute Programme in Environmental Diplomacy.

Five years scientific research and curatorial experience, National Museum of Natural History, Smithsonian Institution, Washington, D.C., USA, with special interests in coral reef ecology, marine algae, and island environments, and continuing activity on various international scientific committees.

Eleven years residence in the South Pacific as adviser to governments and international organizations in ecology, conservation and environmental management, with extensive field experience, including at the grass-roots level. Three years residence in Africa and twenty years in Europe. Wide knowledge of the Asia-Pacific region and of small island developing States, particularly the developing countries and territories of the Pacific Islands, complemented by experience in the Caribbean and Africa, and visits to many other areas.

Thirty-five years programme management and administrative experience in the planning, organization and evaluation of international multi-disciplinary programmes of research, observation, and environmental assessment and management, including liaison with governments, organization of cooperation among international agencies, directing intergovernmental meetings, scientific symposia and training courses, and implementing the results of the United Nations Conference on Environment and Development (Rio de Janeiro, 1992).

Producer of training and audio-visual materials, lecturer and writer (in English and French) for scientific audiences and the general public on ecology, conservation, religion, environment and sustainable development.

Consultant to many international organizations and government agencies, with special emphasis on coral reef and coastal zone management, conservation of nature and biodiversity, environment and management of islands, environmental education and training, indicators of environment and sustainability, rural social and economic development, and applications of science in developing countries.

Academic experience including organizing curriculum development and teaching graduate level courses in social and economic development, coordinator of UNEP/University of Geneva/Graduate Institute Environmental Diplomacy Programme, member of scientific committee for University of Geneva Continuing Education Certificate in Sustainable Development, and occasional lecturer for other university courses.

Recent substantive interests have focussed on coral reef protection and management, information for environmental decision-making, indicators of sustainable development, organization of observations and assessments of the global environment, public participation in environmental observations, new economic paradigms, and the special problems of small island developing States.
