Résumé : |
The water cycle in the Amazon river basin, which drains about one-third of the land surface of South America, is still in equilibrium, with at least 50 per cent of atmospheric precipitation being recycled. However, if large-scale deforestation continued, it could lead to increased erosion and runoff with flooding in the lower part of the basin, reduced evapotranspiration and reducedprecipitation with resulting adverse effects on the climate and agriculture in Brazil. Tabulated data are included on the amounts and distribution of major nutrients in forests and the soil before and after burning and on the rates of erosion and transport of solid and dissolved matter in the system. A bibliography of 83 references is appended. |
