Há exatamente um ano, sob os auspícios da Academia Internacional do Meio Ambiente de Genebra, reuniram­se especialistas brasileiros e suiços, com o intuito de debater e avaliar as alternativas de gestão ambiental. Esta interface é cada vez mais importante, devido, notadamente ao papel do planejamento energético quanto aos impactos deletérios sobre a natureza.

Estado do Meio Ambiente em um País de Escala Continental

Um inventário sobre as principais questões ambientais de um país de escala continental, sujeito a um desenvolvimento desigual, como é o Brasil, constitui­se em tarefa­desafio. Para uma caracterização mínima das criticidades mais berrantes, há que se recorrer a um método de abordagem, o mais apurado possível, a fim de se elaborar um quadro conjuntural efetivamente abrangente e compreensível.

Global Climate and Energy palnning in Brazil

Men’s intervention on nature is such, that it could lead to planetary catastrophes. The scientific community has published their worries about it. Such worries result from a complex association ofwell established theories, experimental data with some margin of error and polemical “ad hoc” models. Three of those questions have been raised recently: the nuclear winter, the hole on the ozone layer and the greenhouse effect. It will be interesting to make parallels among them, to introduce the subject of this paper.

Preserving Brazil’s Tropical Forest Through Emissions Trading

Atmospheric concentrations of carbon dioxide and other greenhouse gases that are produced by human activity have grown rapidly since the beglnning of this century. Unless emissions of these gases are controlled we could face sudden and rapid cllmate changes including an increase in temperature and changes in weather patterns. These changes, in turn, would bring about sea level rise, flooding of low lying areas and destruction of manmade and natural systems. Agriculture could be disrupted and shift geographically. Other effects will include destruction of habitat and of specles that cannot adapt quickly enough, stress on water resources and economic disruption. The Intergovernmental Panel on Climate Change (IPCCI, agroup of scientists estabhshed by the United Nations Environmental Programme and the World Meteorological Organization to study the problem, indicated in a recent report that emissions must be reduced in order to avoid serious consequences 2 . Negotiations are already underway to conslder a climate convention at the United Nations meeting on Environment and Development to be held in Brazil in 1992.
