Variáveis intervenientes na existência de comitês de bacias hidrográficas no Brasil

Abstract

RESUMOA gestão de bacias hidrográficas por meio de comitês é essencial na mediação entre a oferta e a demanda de água para consumo doméstico, industrial, agrícola, lazer, entre outros usos da água. Uma gestão exitosa pode ocorrer por meio da identificação e compreensão das características socioeconômicas, demográficas, entre outras, e assim formatar as práticas adotadas pelos comitês. Neste contexto, o escopo central deste estudo consistiu em analisar as variáveis intervenientes relacionadas aos aspectos geográficos, demográficos, socioeconômicos e a existência de comitê de bacias. A metodologia consiste na abordagem quantitativa, empregando-se uma pesquisa documental secundária e sua análise ocorreu por meio da aplicação da estatística descritiva e do teste de correlação de Pearson. Os principais resultados evidenciam que a explicação da existência de comitês de bacias hidrográficas relaciona-se com o tamanho da população que promove maior pressão à medida que aumenta. Além disso, evidenciou-se que a existência de comitês de bacias correlaciona-se com: crescimento econômico, quantidade de conflitos pelos múltiplos usos, coleta de esgotos e nível de degradação da qualidade ambiental. Conclui-se, portanto, que de fato existem variáveis intervenientes para a existência de comitês de bacias e que eles são necessários para a gestão eficiente destas variáveis.Palavras-chave: demográficos, geográficos, Pearson test, recursos hídricos, saneamento, socioeconômicos. Intervening variables in the existence of watershed committees in Brazil ABSTRACTWatershed management through committees is essential in mediating between water supply and demand for domestic consumption, as well as industrial, agricultural, leisure, and other uses of water. Successful management can occur through the identification and

Virtual water flow and water footprint as optimizer of water resource management in the state of Ceará, Brazil

“…The Southeast region of Brazil faces the main problems of water resources related to the scarcity due to pollution and excessive use of water in urban and industrialized areas, its conflicts of use, and the constant flooding (Porto et al, 1999). Barreto et al (2010) added that the association between water scarcity and disordered economic exploitation causes soil degradation and desertification, in addition to a significant reduction of plant and animal species (Fiel et al, 2017).…”

“…It is important to note that the volume used in the hydrographic basins varies according to the period under analysis for the calculation of the WF, since the WF depends on the volume of water incorporated, the climatic conditions, and the geographical position in question. Barreto et al (2010) and Fiel et al (2017) highlighted that water is used as a strategy in conflict management and environmental protection, which would justify the establishment of hydrographic basin management through the Hydrographic Basin Committees (CBHs), as it seeks a balance between human demand and consumption, animal intake, and irrigation.…”

“…It creates a very high demand for it, causing water scarcity, in addition to degradation through solid and liquid organic waste, chemicals, and soil erosion, among others. Due to this scarcity of water and lack of water quality, there might be stagnation and even a drop in the economic situation (Fiel et al, 2017).…”

“…Based on the results, it was possible to identify and observe the absence of framing according to the current regulation, namely, CONAMA Resolution nº 357/05, in all the situations (Souza and Pizella, 2021). Kaplowitz and Witter (2008), Mahmoud et al (2011), andFiel et al (2017) pointed out that, with the extent of water scarcity putting pressure on existing water management and distribution systems, it is essential to identify and analyze the factors that can change consumption management for efficient management, including river basins.…”
