As many as 673,350 square kilometres of forest may be destroyed in the next 22 years, said the University of Minas Gerais and the Amazon Institute of Environmental Research, whose findings were reported by Rio de Janeiro's O Globo newspaper.
"The damage to the Amazon and to the planet will be irreparable," said researcher Britaldo Silveira Soares, predicting reductions in biodiversity and rainfall, along with an increase in greenhouse gas emissions as trees are burned to clear land.
A government plan to boost highway construction in the Amazon region will also speed deforestation, while poor police surveillance allows illegal logging and other environmental crimes to continue, researchers warned.
In the short term, preliminary figures from Brazil's Environmental Ministry show rainforest destruction accelerated between August and December, after three years of widely touted declines.
Brazilian President Luiz Inacio Lula da Silva said research is under way to confirm those figures and ordered extra federal police and environmental agents to monitor illegal forest clearing in 36 high-risk areas.
Officials promised to block new logging permits and fine those who buy anything produced on illegally deforested land.
Environmentalists say increased demand for soy and beef products has prompted farmers to carve fields and pastures from the Amazon and Sunday's study cites illegal logging as a top cause of deforestation.
Most of the world's remaining tropical wilderness lies in the Amazon, which covers about four million square kilometres and nearly 60 per cent of Brazil. About 20 per cent of the forest has already been razed.
