These relationships that characterize each ecosystem are responsible for essential ecological processes, especially in the field of water especially the influence of these relationships in the different phases of the hydrological cycle. Establish mechanisms for legal protection to consider the hydrologic cycle as the unit is critical to the development of an adequate water resource policy, and establish a management model that overcomes the traditional model in which human needs are placed in the foreground, and results in many cases, do not generate effective conservation of water resources. These issues are examined in this work, and emphasized the need to consider the relationship of water with other natural resources such as forests and other forms of vegetation. The research, using the deductive method, with analysis of scientific studies, standards, case law and doctrine, focused on the importance of a systemic management of water resources, especially in Brazil, a country in which the existence of the Amazon rainforest has a role instrumental in rainfall patterns and therefore the hydrological cycle. The text starts with a brief background to the availability of water on the planet, giving the ways to manage these resources. The paper discusses the mechanisms of management and emphasizes the importance of the relationships in nature to maintain ecosystems in Brazil, especially the Amazon biome. Seeking alternatives for improvement, were identified models of water management options that are in the search for value these relationships, ie, we analyzed models that adopt a systemic approach in water management. It was emphasized also the need to implement this logic in the National Water Resources in Brazil, emphasizing the relationship between water and ecosystems for effective protection of water resources in Brazil. Finally, and after consideration of the systemic view in law, have been identified ways to interpret the rules and points of change in legal texts so as to achieve an effective systemic management of water in the country.Acesso AbertoAtribuição-NãoComercial-SemDerivados 3.0 BrasilÁguas - ecossistemasCiclo HidrológicoRecursos HídricosGestãoDissertaçãoEcossistemas - Recursos Hídricos
