Edited by Juha I. Uitto and Akiko Ono

The United Nations University is an organ of the United Nations established by the General Assembly in 1972 to be an international community of scholars engaged in research, advanced training, and the dissemination of knowledge related to the pressing global problems of human survival, development, and welfare. Its activities focus mainly on peace and conflict resolution, development in a changing world, and science and technology in relation to human welfare. The University operates through a world wide network of research and postgraduate training centres, with its planning and coordinating headquarters in Tokyo.

The United Nations University Press, the publishing division of the UNU, publishes scholarly books and periodicals in the social sciences, humanities, and pure and applied natural sciences related to the University’s research.

The UNU Global Environmental Forum IV, Population, Land Management, and Environmental Change, 25 May 1995, was organized by the United Nations University in cooperation with the United Nations Environment Programme. It was supported by the Global Environment Centre Foundation and sponsored by Obayashi Corporation.
