A partnership with nature. (Environment and Development: A Global Commitment)

Five centuries ago, the discovery of the New World proved that the Earth is round. And therefore finite. Paradoxically, the immense extent of the lands thus revealed enabled human beings to persist until our own times in the mistaken belief that the wealth of nature was inexhaustible and that they could continue with impunity to increase their numbers and multiply their needs indefinitely.

The truth is that the Earth's resources are still considerable, but the race is on between these needs--vital or superfluous--and the means of satisfying them. In spite of scientific breakthroughs and the wonders of technology we are far from sure of winning this race. The rampant population growth that is still going on, especially in the poor countries, and the frenetic consumption of material goods and energy, especially in the rich countries, combine in a model of economic development which weighs too heavily on all the components of our environment and is not "sustainable".

This issue of the Courier, by seeking to provide some insights into the manifestations of this environmental crisis, shows that the latter is equally a crisis of development. Environment and development: the two faces of a single dilemma in the pursuit of human destiny, the subject of the United Nations Conference which will be held at Rio de Janeiro in June 1992.

This is a subject UNESCO knows well and one with which it has been concerned since its inception. It was under UNESCO's auspices that the International Union for the Conservation of Nature was founded in 1948. Around the same time UNESCO launched a scientific programme for the study and use of arid regions. In 1961 the Intergovernmental Oceanographic Commission was established in UNESCO in order to promote worldwide co-operation in the study of the seas, their resources, their protection and their influence on the life of the planet. At the same time study was organized on the Earth's crust, its wealth and the natural hazards associated with it. In 1964 the International Hydrological Decade was launched to further knowledge and management of the water resources of all countries. Finally, in 1968, UNESCO organized a conference on the rational use and conservation of the resources of the biosphere, from which sprang the interdisciplinary programme on Man and the Biosphere (MAB) which is today ...
