“…The water resources in river basins are key determinants of regional development [27,46]. An in-depth analysis of the degree and state of the water resource balance based on the literature can support the efficient utilization of water resources and promote coordinated development of water resources and economic, social, and environmental factors [47][48][49]. Based on the satisfaction function and Gini coefficient, Chen et al built an equilibrium function as a guide and introduced Maslow's hierarchy of needs theory to improve the water resources regulation model.…”

Water resource spatial equilibrium evaluations provide the bases for water resource utilization and allocation. To analyze the regional spatial water resource matching balance, this study constructed a water resource spatial matching model based on the Gini coefficient and Lorenz curve methods. To further reflect the influence of each subregion on the whole region, we combined the correlation number and Gini coefficient methods to propose the water resource spatial balance evaluation method. Herein, we constructed nine Lorenz curve pairs that matched the total water resources and total water use with cultivated land area, population, GDP (Gross Domestic Product) of the secondary industry, GDP (Gross Domestic Product) of the tertiary industry, and agricultural irrigation water consumption. Set pair analysis theory was applied to calculate sample correlation numbers and determine equilibrium levels, which were then compared to Gini coefficient method-based results for Tai’an city evaluation. The results showed that the total water consumption spatial equilibrium in Tai’an city from 2011 to 2020 was favorable, while the total water resource results for Tai’an city greatly differed, especially the balance between total water resources and GDPs of the secondary and tertiary industries, which should be further improved. In practice, quantitative analysis of the water resource spatial equilibrium state in Tai’an city is important for efficient water resource utilization and coordinated development of water resources and economic and social environments.

“…Even though the country still needs more dissemination in research and development for monitoring and treatment of this resource (CHEN, et al [51]). The use of this resource as TUNDISI, et al [52], which is noted in the Brazilian reality are monitoring studies (COOPERMAN, et al [53]), where the quality and potability are evaluated along with the vulnerability of the groundwater resource (LI, et al [54]) and few experiments related to the treatment of this resource or improvement of techniques for this purpose as has been noted in studies already published. In Brazil as reported by RIBAS, et al [55], in their recent study that, although with the national water resources policy and the national basic sanitation plan already in full operation, both the number of municipalities covered by basic sanitation is low and the lack of technology meet the needs of treatment of wastewater that percolates to the subsoil is still slow and with little research and development in the sector, with the major impulses coming from public research entities and still low in number as shown in Figure 2.…”

The hydrological water cycle comprises constant water movements, which have great influence on the maintenance of vital natural activities. Groundwater in particular constitutes a portion of aquifers, which are considered mobile reservoirs used mainly as a source of supply and human consumption. However, external influences have become largely responsible for the unbalance of the ecosystem, linked to the unbridled human consumption of finite natural resources and the consequent discharge of waste into the receiving bodies without the necessary treatment. The geological water cycle is interrupted when forests are cut down, springs and rivers are extinguished, and together with this, finally, the lack of basic sanitation alters the ecosystem, causing changes of great relevance to the world's population. Groundwater has suffered relevant impacts due to the loss of biodiversity of ecosystems, such as contamination, overuse, lack of current regulatory legislation for use, and the improvement of decontamination techniques. The analysis of the following activities is necessary, mainly due to the anthropic punctual impacts to the ecosystem, corroborating the need for satisfactory techniques. It is noticeable the need for extreme attention to the waste runoff via sanitary sewage to places that have treatment, but the same is not very efficient in retaining this liability, since some developing countries that have not reached about 90% treatment of sanitary sewage, demonstrating the lack of such activities. Thus, the objective of this study is to verify, by means of exploratory and bibliographic research in research bases, the measures that protect the water. Technological measures and sustainable management tools for this purpose will be reviewed, as well as the evolution of groundwater treatment techniques.

“…Currently, the inequality of water resources and the spatially mismatch between water and other elements have been increasingly discussed at various levels, from grid to prefectural, basin, and national level [6][7][8][9]. In China, regional studies focusing on water resource equilibrium have mainly concentrated in the northern arid and semi-arid region [10,11]. Previous researchers addressed that a water inequality can aggravate the water conflicts between different sectors and regions.…”

The spatial-temporal mismatch of water resources and socio-economic development in rapidly urbanized regions has been the focus of water resource management, and is one of the main limitations to sustainable development goals (SDGs). Guangdong Province is represented by a highly developed economy and society, and has been undergoing disproportionately rapid population growth during the past two decades. The uneven distribution and spatial mismatch of water resources have aggravated the contradictions between water supply demand. In this paper, we evaluate the matching degree of water resources and social economic elements, detect the spatial-temporal changing pattern of the matching degree, and reveal the changing mechanism using the combined methods of the Thiel index, the space–time Gini coefficient, and the Lorenz curve. The results show that (1) the temporal matching is relatively balanced and reasonable, while the spatial mismatch is prominent and deteriorating constantly, especially the connection between the amount of water and GDP; (2) the water volume pressure is mainly concentrated in the Peral River Delta and eastern and western Guangdong, while water consumption stress is relatively lower in northeastern Guangdong; and (3) the water volume inequality is dominated by an intercity difference and is primarily caused by regional differences. Based on the results, policy implications, such as the implementation of integrated water resource management plans, investment in the development of alternative water sources, as well as enhanced public education and the establishment of a water saving society, have been provided to alleviate the mismatch issue between water elements and socio-economic parameters, and to push the realization of water-related SDGs.
