Resumo

Large river basins which includes the largest river in the world, added to climatic conditions as constant temperature, high humidity and intensive precipitation rates on Amazon leads to a misinterpretation that there are no problems related to water resources in that region. However, hundreds of indigenous communities located in the upper Negro River have recently experienced an extreme drought observed in the beginning of 2018 year that impacted negatively the inhabitants way of life in that region, at least for that period. This work aims to characterize the hydrological events occurred at the beginning of the year 2018 in the upper Rio Negro region, evidencing the impacts of these events on the indigenous population. Precipitations in February and March were less than 30% of the average observed in the stations historic series what explains reports by the population of losses in agriculture, notated for cassava production. The low water levels observed in the rivers, associated to less than 1% of permanency, were also able to cause injuries to the Negro river population, and population reports emphasized fishing and agricultural problems. These injuries were also related to difficulties in population mobility and transportation of consumer goods, that is made mostly by fluvial ways. The low water levels also affected the access of population to public services, health units and basic feedstocks since in a great amount of cases the population needs to be displaced to urban centers.
