“…In this way, assigning a monetary value to water (and other environmental goods) can contribute to sensitizing users to their dependence on these resources. Consumers must be aware that the quality of such environmental services is dependent on anthropic activities, particularly in the areas of livestock and agriculture, which are two economic activities that require water to produce products for the consumer market (FACCO et al, 2021).…”

In Brazil, several legal instruments are used to control water use, including subsidies and revenue collection for the use of this resource. The objective of this study is to evaluate water vulnerability and willingness to pay or receive for water use and conservation in the state of Pará between 2008 and 2017.The method used was exploratory, with quantitative and qualitative scope. The data obtained indicated the issuance of grants for groundwater use was most frequent (n = 4,262). For the relationship "types of grants issued and types of interference", the highest mean value (404.1 ± 159.8) fell to "granting law". Regarding the seven hydrographic macro-regions of Pará, the "Northeast Atlantic Coast" received the highest number of grants issued (n = 4,115), whose destination of half of them (n = 2,069) was for human supply; the smallest quantity (n = 5.0), was for "firefighting". Of the 10 hypotheses regarding the purposes of water use and the issuance of a permit, two of them (dams for water volume regulation and firefighting) were not significant in this regard (p<0.05), while the remaining eight were significant. These findings thus indicate that there are still numerous obstacles to the effective implementation of charging for water use through the allocation of water resources in the state of Pará. The insufficient number of watershed committees (n = 1.0) in the state are considered the main obstacles that hinder users' willingness to pay for water conservation.

Natural resources, such as soil and water, play a crucial role in sustaining life on Earth. When used appropriately, these resources can mitigate environmental impacts. However, inadequate soil management practices can result in negative effects, such as the intensification of erosion processes and significant losses of soil, water and nutrients essential for plant growth. Thus, considering that the Farinha River basin - MA is located in the Cerrado biome and has a large part of its area occupied by highly erodible soils, the aim was to quantify water, soil and nutrient losses using a rainfall simulator. The experimental design adopted was entirely randomised (DIC), in a bifactorial scheme with 5 replications. Factor 1 considered two types of soil management systems (Anthropised Area and Non-Anthropised Area), while factor 2 involved three simulated rainfall intensities (80mm.h-¹, 110mm.h-¹ and 130mm.h-¹). The response variables assessed were losses of water, soil and nutrients and organic matter.The averages were subjected to analysis of variance and, if significant, the Tukey test was applied at 5% probability using Past 4.03 software. The results indicated significant losses of soil, water and nutrients associated with both the soil management system and the rainfall intensities, as well as making it possible to quantify the nutrients lost in runoff water on site. The conclusion is that the combination of inadequate soil management practices and intense rainfall can exacerbate erosion processes and the leaching of macro and micronutrients, resulting in an increasing need to incorporate fertilisers and correctives into agroforestry activities. Furthermore, it is important to emphasise that water erosion also contributes to an increase in soil and nutrient loss, which can lead to adverse environmental impacts, such as contamination of water resources and degradation of soil quality.
