Abstract

The Amazon is the largest stream in the world. Its basin covers at least 7. lo6 km2, which represents - 5% of the global continental area and almost 70% of the area of the continents localized in the equatorial zone, between 5"s and 5"N of latitude. The global tropical moist forest covers -9.35. lo6 km2, so that the Brazilian evergreen rain forest represents at least 50% of this area. At Obidos, the most accessible downstream station for collecting data, the area concerned is 4.619- lo6 km2. The purpose of these two extended abstracts is to show how changes and oscillations of climate can significantly affect erosion as well as carbon and nitrogen cycles, and may also mask the degradations of the environment due to deforestation.
