A dinâmica sazonal do rio Amazonas: os impactos socioambintais da estiagem de 2023 na microbacia do "Zé Açú" no municipio de Parintins-AM

Abstract

The research work on the seasonal dynamics of the Amazon River and the socioenvironmental impacts of the drought in the Zé Açu microbasin brings to light the difficulties faced by the rural communities that border it due to the period in which the water le vel reaches critical levels, such as in the year 2023. This drought is the longest in the last 120 years of monitoring the Negro River in Manaus. Navigability and use for other purposes were compromised, as well as a threat to aquatic ecosystems. To this e nd, the objectives of the research, in general, are to understand the seasonal dynamics of the Amazon River and the socioenvironmental impacts in the Zé Açu microbasin in Parintins Am. More specifically: Identify extreme flood and low water events over a 23 year period (2000 2023); record the main affected areas in the Zé Açu watershed and; list the main problems caused by extreme drought and low water events. To this end, a methodology based on bibliograp hical research and the case study method was used. However, there is a need for greater care with the Zé Açu watershed, so that all natural functioning can be maintained both during drought and when the channels are full. This is a reality, in addition to the damage to the flow of family farming production, it already causes conflicts in the region, due to the need to establish access roads to Paraná do Ramos, within private properties.
