Abstract: The southern border of the Brazilian Amazon is one of the most sensitive areas to deforestation in Brazil. Pondering problems related to changes in land use, new issues are emerging , such as , climate change and its negative effects on the regional hydrological cycle. The higher frequency of El Niño and La Niña seems to have strong influence on rainfall in Amazonia. They are becoming more lasting and intense in the course of the last 20 to 30 years compared to the past 100 years. This paper may confront the scientific knowledge of the relations of climate and water resources in Amazon with the points of vulnerability that anthropic societies present in the region. The impact of climate change is not uniformly borne by different regions and populations. Actually, individuals, sectors and systems are affected to varying degrees and , besides, they may be prejudiced to a greater or lesser extent. These impacts vary in magnitude and intensity in accordance with certain aspects, for instance, geographical location, time, the prevalent social, economic and environmental conditions and the infra-structure of a given location. A comprehensive description of these extreme climate events is one of the first steps to a regional vulnerability approach. Copyright Springer Science+Business Media B.V. 2012
