“…The agricultural sector is divided into activities related to agriculture, livestock, fish, and plant extraction. Raw water is consumed in the production processes related to these activities (Soares et al, 2021). Among these sectors, the consumption of raw water is the highest in agriculture in Ceará, with 60.1%, whereas the service sector accounts for 32.6% of the water consumption, followed by the industry (7.2%; Soares et al, 2021).…”

However, the least water is consumed in the sector that pays the highest tariff, that is, the industry, whereas the fees paid by the largest consumer of water, that is, agriculture/irrigation and fish farming, are the smallest.…”

Economic instruments, such as water charges, have been used to promote water conservation and raise funds for basin management. However, there is a need to improve the water collection model in Brazil. The aims of this study were to analyze the evolution of raw water charges in the State of Ceará and verify the effect of drought on the costs and water collection from 2011 to 2019 to answer two questions: does the water collection fulfill its function of financing the water resources system? Is the pricing model flexible to absorb the effects of climate variability? We conducted a content analysis to determine the presence of certain words in selected documents, and then analyzed the costs of system operation. The results show that the payment capacity is lower than the tariff applied to water. The Status Index is negatively correlated with the Administration (ADM) and Operation and Maintenance (O&M) costs. The generated revenue is mainly used to cover the management costs (ADM and O&M); however, it is insufficient to finance the implementation of measures, programs, and projects to improve the water management in respective basins. Thus, a floating tariff should be established in which the water scarcity and effects of climate variability are incorporated.

Water consumption generated by the economic structure exhibits spatial variation within a territory due to the influence of economic and geographical factors that impact the demand and supply of water. Thus, this study assessed the spatial dependence of total water consumption through the use of Exploratory Spatial Data Analysis (ESDA). For this purpose, two statistical tests of spatial autocorrelation were applied: The Global Moran's Index (I) and the Local Indicator of Spatial Association (LISA). The spatial structure of the data was determined by the Rook-type spatial contiguity matrix. Positive spatial autocorrelation was found based on the analysis of the Global Moran's I statistic. It was observed that consumption is not evenly distributed in its geographical space, indicating the formation of clusters of municipalities with High-High, High-Low, Low-High, and Low-Low aggregation patterns. In the univariate analysis of total water consumption by LISA, clusters of municipalities with High-High aggregation were identified in the Hydrographic Regions of Baixo Jaguaribe, Curu, Litoral, Médio Jaguaribe, and Bacias Metropolitanas, indicating a strong positive association between the consumption in these regions and their neighbors. In the bivariate analysis between total Water consumption and Gross Value Added of the municipalities in Ceará, two more Hydrographic Regions with High-High aggregation were identified, in addition to those already identified in the univariate analysis, namely Acaraú and Banabuiú. Thus, the study identifies spatial clusters that are essential for identifying regional inequalities and facilitating decision-making in the allocation of water resources.

Interactions among society, water resources, and environment systems have become increasingly prominent with the progressively far-reaching impact of human activities. Therefore, this paper aims to construct a co-evolution model to establish the mutual feedback relationship among society, water resources, and environment from the perspective of socio-hydrology. Firstly, social factors such as environmental sensitivity, environmental protection awareness, and technological level are introduced to this model to describe the coevolutionary trajectory of society, water resources and environment subsystems. Then, this model is implemented in 11 provincial administrative regions in the Yangtze River Economic Belt, and the degree of coordination of their coupling is evaluated. Results show that the water-use efficiency of each provincial administrative region in the Yangtze River Economic Belt gradually increases during the forecast period. The coupling-coordinated degree of each provincial administrative region of the Yangtze River Economic Belt has greatly improved during the 14th Five-Year Plan period, reflecting that policy support has played a significant role in the coordinated development of the Yangtze River Economic Belt. The dynamic fluctuation process of environmental sensitivity effectively depicts the co-evolution process of the coupling system, which provides a reference for the subsequent exploration and cognition of the human-water coevolutionary mechanism.
