Dwindling Ground Water Table: An Ecological Study of Southern Haryana

The dwindling ground water level is one of the critical issues that plague India in the present times. This research study primarily has its basis in the secondary data, gathered from the Ministry of Water Resources. The main aim of the present research study is to highlight the issues related to ground water in various parts of India with the main focus on southern part of Haryana state. The spatial pattern of the ground water depth is studied using the secondary data from various sources. The water table depth and fluctuation maps in Arch GIS 9.3 are analysed by making use of geological analysis extension. The water elevation is examined by employing the Kriging estimator. Also, the different ways of prevention that can help in checking the quick dwindling of ground water table are discussed so that the sustainable use of ground water can be encouraged and achieved. It is observed that the menace of ground water depletion has posed alarming threat to the states of Punjab, Haryana, Uttar Pradesh and some south Indian states. This is attributed mainly to the agricultural, industrial and human needs amidst the ever-rising rate of population in India. In the southern Haryana, the Mahendergarh district and Firozpur block of Mewat area have been identified as most critical zones in relation to water depletion. The study suggests judicious and sustainable use of water resources so as to check the alarming dwindling of the ground water table.

Study on a Stomatal Conductance Model of Grape Leaves in Extremely Arid Areas

Stomata are essential for regulating the exchange of water and energy between plants and the atmosphere. In the context of climate warming, especially in extremely arid regions, the knowledge of stomatal conductance variation patterns is fundamental to the study of crop evapotranspiration, productivity and drought resistance characteristics. The accurate simulation of stomatal conductance in this region is an important prerequisite for the optimal regulation of the crop growth environment. In this study, a two-year field experiment was carried out in vineyards in an extremely arid region. The Jarvis model and BWB model were used to evaluate the daily changes in stomatal conductance. The results showed that stomatal conductance was significantly correlated with environmental factors (temperature difference between leaf and air (ΔT), photosynthetically active radiation and air temperature). The Jarvis and BWB models performed well. However, the response function of the environment factor in the Jarvis model can affect the model performance. The ΔT effectively improved the model, and the modified Jarvis model outperformed the modified BWB model. The R2 and model slope b of the modified Jarvis model increased by 45.18–70.37% and 2.51–3.12%, respectively. RMSE and MAE decreased by 38.98–43.12% and 42.69–44.35%, respectively. Overall, the Jarvis3–ΔT model had a good effect on the simulation of the daily change of stomatal conductance during the critical period of grape growth, and the Jarvis3–ΔT model was the best stomatal conductance model in this study. The results of the study are of great significance for further improving the sustainable use of water resources in grapevines in extremely arid regions.

Quantitative detection and attribution of soil moisture heterogeneity and variability in the Mongolian Plateau

As an essential state variable of the earth’s terrestrial system, soil moisture (SM) is highly significant regarding hydrological processes, agricultural production, land management in response to issues like soil erosion etc. However, the net effects of different environmental factors on the heterogeneity and variations of SM remain unclear, due to the complex interactions between variables. Indeed, investigating such effects in the highly climate-vulnerable Mongolian Plateau is imperative for water resource management and climate change adaptation. In this study, we analyzed the contributions of different environmental factors on the spatial heterogeneity and variations of SM in the Mongolian Plateau between 1982 and 2020, using a geographic detector model (GDM) and a novel nonlinear Granger causality model. The results of the GDM analysis demonstrated that precipitation and vegetation were the main controls relevant to SM heterogeneity, with their explanatory powers (Q statistics of GDM) found to be higher than 0.67. In two breakpoints—one in the early 1990′s and another in 2007—SM demonstrated a pattern of increase, then a decrease, subsequently followed by an increase (insignificant decrease in SM at 100–289 cm depth only). Precipitation was identified as the Granger causal of SM variations over 33.39–97.65% of the plateau’s vegetated area, leading to the drying up of 40% of its SM. The greatest contribution to SM in 28–289 cm of the plateau was observed as coming from one-month-old precipitation, due to the lag in the manifestation of effects. Further, rising temperatures were found to have an immediate influence (2.73–5.23%) on SM in 14.61–54.90% of the whole plateau’s vegetated area, an impact which was relatively high (>14%) in its northeastern wetting zone. Vegetation change posed a relatively weak effect (<2%) on SM over a limited area of the plateau (27.75–35.42%). Although lesser than the impacts of general climate changes, the contributions of climatic extremes could not be neglected, ultimately accounting for up to 10% of SM changes. In summary, this study provides new insights into the individual contributions of various environmental factors on the spatial heterogeneity and variations of SM in the Mongolian Plateau, offering vital information for policymaking regarding climate change mitigation and adaptation, sustainable use of water resources, and ecological restoration for arid and semi-arid region.

Evaluation on real-time self-organization algorithm of forest cultivation, tea planting and tea processing for sustainable ecosystem management of agricultural water resources

Abstract Agricultural water resources are water resources that can be used for agricultural production, including surface water, groundwater and soil water. The sustainable use of water resources is of great significance to agriculture and rural economy. In the context of climate change and the increasing crisis of water resources, how to effectively use forest resources and other natural resources to achieve sustainable management of agricultural water ecosystems has become an increasingly urgent issue. Therefore, this paper proposed a real-time self-organization algorithm for forest cultivation, tea planting and tea processing for sustainable ecosystem management of agricultural water resources. This paper first described the sustainable ecosystem of agricultural water resources, carried out optimization analysis on tea planting and processing technology, using the genetic optimization algorithm based on decision tree and then carried out an experimental analysis on a tea garden. It can be seen from the data that the average monthly temperature of the tea garden cultivated by the algorithm in this paper was between 13.4 and 20.5 °C and the average annual temperature was 16.16 °C. However, the average monthly temperature of the traditional cultivation method was between 11.5 and 16.8 °C and the average annual temperature was 13.64 °C.

Measurement of water resources carrying capacity in Gugang Town of Central China based on human-water-agriculture framework

More research has revealed that central China is one of the most vulnerable areas to a water crisis because of limited and unequally distributed water resources as well as rising water demands. Also, climate change is expected to reduce water resources dramatically, resulting in increased competition among users and severe water shortages for irrigated agriculture. The township, the most basic level of the Chinese government system, urgently needs to compare water allocation based on different management strategies to define the most optimized water management plan. The concept of a “human-water-agriculture” evaluation system was proposed in this study to couple and coordinate human well-being, sustainable water resource use, and agricultural development in Gugang Town, China. Within this framework, twenty-five indicators were chosen from the criterion layers to assess and optimize the carrying capacity of water resources for historical periods and the future year 2030. The results showed that the WRCC was bearable in previous years, except for 2018 when the percentage of water shortage reached 19.5 % because of a sharp reduction in dynamic surface water availability. The static surface water, represented by the water restored in hilly ponds in village and town areas, was discovered to account for up to 17 % of the total amount for the dry year. The WRCC would be overburdened in 2030, with 61.6 % and 18.1 % water-deficient underwater supply at 90 % and 75 % guarantee rates, respectively. The WRCC states that effective optimization of agricultural water allocation for crops to maximize economic benefits with limited water consumption could significantly improve human and agricultural systems. This study investigated a route for studying WRCC in village and town areas, providing theoretical and practical guidelines for local water-adapted development.

The role of water as a significant resource in UGGps results of an international workshop

Water resources are becoming increasingly scarce in many parts of the world. The protection and the sustainable use of water resources is highly relevant to mitigate climate impacts. This article aims to investigate the activities of UNESCO Global Geoparks (UGGps) in regard to ground and surface water resources. Using a mixed-methods approach, a questionnaire was administered and an international online workshop was held. The results show that there are various common fields of activities and common threats in regard to water resources. The identified topics are structured and discussed within a SWOT analysis. The article provides a starting point for UGGps to jointly promote water as a significant resource and to define common fields of activities that can be supported by the UNESCO Global Geoparks Network (UGGpN). The article recommends the establishment of a new working group within the UGGpN. This will provide a platform to exchange best-practice experiences and develop guidelines on how to effectively integrate the protection and sustainable use of water resources into the management of UGGps.

Can the water resources tax policy effectively stimulate the water saving behavior of social water users? A DSGE model embedded in water resources tax.

Whether the implementation of the water resources tax policy can stimulate the water-saving behavior of social water users is one of the important criteria for evaluating the implementation effect of the tax reform policy. Taking Hebei Province, the first tax reform pilot in China, as an example. A dynamic stochastic general equilibrium model (DSGE) with embedded water resources tax is constructed to simulate the persistent impact of water resources tax on water-saving objectives. The research shows that: (1) Water resources tax can effectively achieve the goal of water-saving and improve the utilization efficiency of water resources. (2) Levying water resources tax helps to improve the water-saving awareness of enterprises and residents. It can also encourage enterprises to optimize production structures. (3) Rational and efficient use of special water resources protection funds is the basis for ensuring the effective implementation of water resources tax. It can also improve the recycling capacity of water resources. The results show that the government should speed up formulating a reasonable water resources tax rate and accelerate the construction of water resources tax protection measures. To ensure the relatively steady state of water resources utilization and protection, and achieve the dual goals of sustainable economic development and sustainable use of water resources. The research results of this paper reveal the internal logic of the comprehensive impact of water resources tax on the economy and society and provide an important basis for the national promotion of tax reform policy.

Impact of the Russia–Ukraine armed conflict on water resources and water infrastructure

The armed conflict between Ukraine and Russia that began in late February 2022 has far-reaching environmental consequences, especially regarding water resources and management. Here we analysed the multifaceted impacts of the military actions on freshwater resources and water infrastructure during the first three months of the conflict. We identified the nature of the impacts, the kind of pressures imposed on the water sector and the negative consequences for the availability and quality of freshwater resources for the civilian population. Our results showed that many water infrastructures such as dams at reservoirs, water supply and treatment systems and subsurface mines have been impacted or are at risk from military actions. Continuation of the conflict will have multiple negative sustainability implications not only in Ukraine but also on a global scale, hampering achievement of clean water and sanitation, conservation and sustainable use of water resources, and energy and food security.

Water narratives in local newspapers within the United States

Sustainable use of water resources continues to be a challenge across the globe. This is in part due to the complex set of physical and social behaviors that interact to influence water management from local to global scales. Analyses of water resources have been conducted using a variety of techniques, including qualitative evaluations of media narratives. This study aims to augment these methods by leveraging computational and quantitative techniques from the social sciences focused on text analyses. Specifically, we use natural language processing methods to investigate a large corpus (approx. 1.8M) of newspaper articles spanning approximately 35 years (1982–2017) for insights into human-nature interactions with water. Focusing on local and regional United States publications, our analysis demonstrates important dynamics in water-related dialogue about drinking water and pollution to other critical infrastructures, such as energy, across different parts of the country. Our assessment, which looks at water as a system, also highlights key actors and sentiments surrounding water. Extending these analytical methods could help us further improve our understanding of the complex roles of water in current society that should be considered in emerging activities to mitigate and respond to resource conflicts and climate change.

Spatial-Temporal Characteristics and Influencing Factors of Lake Water and Groundwater Chemistry in Hulun Lake, Northeast China

Lakes in cold and arid regions are extremely vulnerable to global climate change, and the study of seasonal spatial and temporal fluctuations of lake-groundwater chemistry is of major significance for water resource management and environmental preservation. In this study, we combined hydrogeochemical, multivariate statistical, and spatial interpolation methods to assess spatial and temporal variations of lake and groundwater chemistry in Hulun Lake during the frozen and non-frozen periods. The results show that sodium (Na+) is the most abundant cation in the Hulun Lake area. Bicarbonate (HCO3−) and sulfate (SO42−) are the most predominant anions in the lake, river, and ground water during both seasons. The higher Na+ + K+ concentrations in the frozen season were related to longer circulation time and lower renewable rate. The water chemistry of the lake was of the HCO3-SO4-Cl-Na type and that of groundwater in the east and west regions was of the SO4-Cl-Na and HCO3-Na types, respectively. The chemical compositions of groundwater in the non-frozen season were mainly affected by evaporation and concentration, while rock weathering, evaporation, and human activities jointly controlled groundwater chemical component in the frozen period. Based on hierarchical cluster analysis (HCA) and principal component analysis (PCA) methods, Ca2+, NO3−, and SO42− were identified as the main controlling indicators of the chemical characteristics of groundwater and lake water. The increase of Ca2+ concentration in the center of the lake was related to groundwater discharge along the marginal tectonic fracture zone along the lake shores, which was the potential groundwater discharge area. The unconsolidated aquifer provides recharge channels for groundwater on the eastern side, which has a certain influence on the increase of nutrient concentration (NO3−) in the lake on the eastern shore. This research adds to our rough understanding of the lake-groundwater interaction in Hulun Lake, and provides a scientific foundation for the sustainable use of water resources, as well as the eco-logical integrity preservation in cold and arid regions.

The Impact of Water Resources Tax Policy on Water Saving Behavior

The Chinese water administration department has continuously explored and formulated regulatory and market-oriented water control policies to alleviate the contradiction between water shortage and economic and social development and promote the new idea of ‘water-saving first’ water control. Among them, implementing a water resources tax policy as a price means has achieved initial success. The water-saving effect of water resources tax collection is one of the important bases for determining whether the tax reform will be promoted nationwide in the next stage. Based on this, taking Hubei Province, the first tax reform pilot in China, as an example, water resource elements are integrated into the economic system and a dynamic stochastic general equilibrium model (DSGE) is constructed, embedded in water resources tax to simulate the persistent impact of such a tax on water saving objectives. The research shows that: (1) A water resources tax can effectively achieve the goal of water-saving and improve the utilization efficiency of water resources. (2) Levying a water resources tax helps to improve the water-saving awareness of enterprises and residents and promotes enterprises to optimize their production structure. (3) Rational and efficient use of special water resources protection funds is the basis for ensuring the effective implementation of a water resources tax. It can also improve the recycling capacity of water resources. This means that the government should speed up the exploration of the relationship between supply and demand for comprehensive water resources, to establish a reasonable range of water resources tax rates to guarantee people’s livelihoods, and to accelerate the construction of water resources tax guarantee measures, in order to achieve a relatively steady-state of water resources utilization and protection, realizing the dual goal of sustainable economic development and sustainable use of water resources.

Biochar-Based Photothermal Hydrogel for Efficient Solar Water Purification.

The development of technology for solar interface evaporation has a significant meaning for the sustainable use of water resources in remote regions. However, establishing a solar evaporator with a high evaporation rate and favorable water treatment capabilities remains challenging. In this work, we reported a silver nanoparticle (AgNP)@carbonized cattail (CC)/polyvinyl alcohol (PVA) composite hydrogel (ACPH) membrane. Because of the successfully loaded AgNPs, which have a photothermal synergy with the CC, the ACPH-10 membrane obtained an excellent photothermal conversion performance. Additionally, the hydrophilicity of the ACPH-10 membrane ensures a sustainable water supply which is necessary for the improvement of the evaporation rate. Therefore, the ACPH-10 membrane achieves an evaporation rate of 1.66 kg m-2 h-1 and an efficiency of 88.0%, attributed to the remarkable photothermal conversion and water transmission. More importantly, the membrane exhibits superior purification ability in a variety of sewage. Pollutant removal rates in heavy metal and organic dye sewage have exceeded 99.8%. As a result, the ACPH membrane holds great promise for wastewater recovery and seawater desalination, which can aid in resolving the water crisis issue.

Comparative Assessment of Seasonal Variations in the Quality of Surface Water and Its Associated Health Hazards in Gold Mining Areas of Osun State, South-West Nigeria

Industrial and urban development are contributing to an increase in global environmental degradation. Therefore, the release of heavy metals from mining-related operations into surface water is harmful to human health. But as anthropogenic influences on the environment grow, surface water characteristics are also alter, impacting aquatic creatures. In order to analyze the acceptability of the surface water in the gold mining area for drinking and irrigation uses, different quality water assessment methodologies were incorporated in this research. In light of this, the purpose of the current study is to comprehend how the hydrogeochemistry and appropriateness of surface water for drinking and irrigation vary every month. The study employed standardized analytical techniques. According to APHA recommendations, all sampling, conservation, transportation, and analysis were completed (2012). All collected samples were transported to the study lab while being kept in an icebox to prevent the degradation of the organic components. As a result, the study is focused on the contamination level in the surface water for a year. Overall, the study highlights important pollutants impacting surface water quality as it passes through Osun State's gold mining regions. Finally, it has been determined that the following criteria are crucial for the stretch of this research season: DO, Hardness, Turbidity, Chloride, Potassium, Nitrate, Lead, TSS, Cadmium, Chromium, Sulphate, Manganese, Mercury, and Arsenic. Most of the physicochemical variables examined in this study fell within their corresponding standard limits. Based on the results of this study, the appropriate constituted authority is encouraged to continuously monitor and assess surface water quality suitability for drinking, domestic, and irrigation purposes by keeping track of the effects of water contaminants and detecting any changes in the water quality. To safeguard and maintain groundwater quality and public health, it is advised that appropriate regulatory policies and water treatment procedures be employed in the area. Additionally, it is proposed that when enhancing water quality and investigating the sustainable use of water resources, surface water pollution should be taken into consideration.

A Review on the Water Dimensions, Security, and Governance for Two Distinct Regions

Non-arid region countries, including Canada, enjoy abundant water resources, while arid countries such as Qatar struggle to meet their water needs. However, climate change threats to water resources are similar for both climatic regions. Therefore, this article discusses water dimensions, security, and governance for these different regions, i.e., non-arid Canada and arid Qatar, that distinctly respond to their water-related challenges. Limitations of the article include lesser water-related literature availability for Qatar than for Canada. Canada’s water resources appear vulnerable to climate change as it is projected to face &gt;0.6 °C above the global average of 1.6 °C for the 20th-century temperature. Qatar is extremely vulnerable to dust storms, and rising sea levels, with the maximum temperature approaching 50 °C during the summer, and flooding during the winter. The sustainable use of water resources needs to address social, economic, political, climate change, and environmental dimensions of water. Other than climate change impacts and high per capita consumption of water, Qatar faces challenges of a rise in population (~29 million as of now), acute shortage of freshwater from rainfall (~80 mm per annum), high evapotranspiration (~95% of the total rainfall), depletion of groundwater, and low agricultural productivity due to infertile lands and water scarcity, all leading to food insecurity. The sustainable use of water resources requires improved regulations for water governance and management. Comparisons of water sustainability issues, dimensions, security, and governance facilitate discussions to improve water governance structures for resource sustainability, food security, and climate change adaptability, and show how one country could learn from the experiences of the other.

INDICATOR OF SUSTAINABLE WATER RESOURCES USE IN THE TRANSBOUNDARY BASINS

Due to the complex situation of integrated water resources management in transboundary river basins, this research built a set of indicators for sustainable use of water resources by the Delphi method and developed a specific calculation method for 22 indicators of 5 groups. The integrated indicator has 5 assessment levels to demonstrate the magnitude of water use and the renewability of water resources. Using these indicators to evaluate the sustainability of three border provinces in the Mekong transboundary basin which are Kontum, Attapue, and Ratanakiri, this research came to the conclusions that 9/24 districts in three provinces have moderate water use and renewable water resources level; the remaining districts are also using water at a moderate level but with low renewable water resources. Furthermore, research results showed that different governmental policies generated varying impacts on the sustainable use of water resources in three provinces. Hence, this research is an important scientific foundation for the authorities to build cooperative water resource management programs in transboundary river basins. In future research, the availability of a more detailed dataset will enable the construction of a more comprehensive water resource management plan for different phases.

Evaluation of water resources: A case study of Rohtak district, Haryana

Water is one of the most important natural resources for life. Because of the rapid increase in population, urbanization, and industrialization, the demand for water to meet various needs is constantly increasing. Water that is present below the Earth's surface and fills any gaps in the soil or geologic strata is known as groundwater. It is additionally known as subsurface water. Data related to underground water table were obtained from Central Ground Water Board of the Ministry of Water Resources. Maps of underground water table depth, quality and surface water resources were prepared in Arc GIS software. After the analysis of maps, the depth of the underground water table in the study area ranges from 0 to 20 meters. The maximum area of the study area is 3-10 meters, which covers 48.35% of the study area. The minimum area is 10-20 meters deep and covers 1.43% of the study area. In Rohtak block, the maximum depth is observed in the villages of Brahmanvas, Chamaria, Aryanagar, and Bohar. The quality of groundwater varies from fresh to saline. Fresh underground water quality occupies the largest area, accounting for 59.8% of the study area. Saline underground water quality accounts for 0.5% of the study area. In terms of surface water resources, this district lacks a perennial river. The main irrigation channels in this area are artificial drain no. 8 and sub drains, major canals, distributaries, and minor canals. This research paper will make a better understanding of water resources in Rohtak district. It will help to analyse and understand the current status of underground water depth, quality and surface water to build up any water resource management plan. A water resource management plan will ensure the sustainable use of water resources which is very important for our ecosystem.

Economic efficient use of soilless techniques to maximize benefits for farmers

&lt;abstract&gt; &lt;p&gt;The main challenge of the agricultural sector is the increasing pressure on natural resources, mainly water and arable land. Consequently, an urgent imperative arises to explore technological advancements that can boost food production in alignment with the growing demands. The Soilless Production System (SPS) emerges as a proficient approach for managing irrigation water, thereby making a significant contribution to food security. This research focuses on the efficient use of SPS and identifies the best economic use of the soilless techniques for different crops within an area characterized by limited land and water availability. The database for the study was generated through a farm survey to investigate the benefits of adopting SPSs as a sustainable agricultural practice. A linear programming approach was applied to develop an optimization model for resource allocation and crop mix selection, considering the development opportunities through the SPSs. Different scenarios were applied in the model. The results proved that adopting SPSs is a sustainable irrigation practice, since the technique promotes water use efficiency, generates profitability, and conserves the associated natural resources. The SPSs ensure sustainable use of water resources by increasing water use efficiency. The hydroponics cultivation system had 11 ± 1.7 times higher yields but required 82 ± 11 times more energy in comparison to the lettuce crop produced by the conventional production system (CPS). The result of the optimal solution shows that the total revenue of scenarios of the study is 109% of the revenue of the original value of the largest farmer. The water resources and the investment cost as constraints in the model are totally used, but the operational costs in the optimal solutions are 74% of the total operational cost in the original data. The optimal solution showed the importance of using computerized systems in which the control of the fertigation is better.&lt;/p&gt; &lt;/abstract&gt;

Water resources have become a major factor limiting the sustainable development of China’s economy and society, and at the same time China’s water resources are developed and utilized in a relatively sloppy manner, China is facing multiple pressures of population, resources and environment, and the problems of water shortage, water environment deterioration and flood disaster prevention are becoming increasingly prominent. The rapid development of economic and social demand for water resources is increasing, and the people’s desire to improve the ecology and environment is becoming more and more urgent. How to fully consider the sustainable use of water resources, effectively solve the contradiction between water demand and supply, development and protection, improve the level of planning and scientific decision-making, promote economic development and water carrying capacity to adapt to accelerate the transformation of economic growth and structural adjustment is of great importance.

Water Resources Evaluation in Arid Areas Based on Agricultural Water Footprint—A Case Study on the Edge of the Taklimakan Desert

Water scarcity is an important factor limiting agricultural development in arid areas. Clarifying and evaluating the current situation of water resources in arid regions is helpful for decision-makers in the rational use of water resources. This study takes a typical arid region located at the edge of Taklamakan Desert-Hotan region as the study area. The water footprint (WF) of the Hotan region was calculated based on 20 years of data information from 2000–2019. An evaluation system was established using four aspects of the WF: structural indicators, efficiency indicators, ecological safety indicators, and sustainability indicators. The results show that the WF of the study area is mainly dominated by blue water consumption, with a proportion of 65.74%. The WF of crop production is larger than that of livestock production. The produced WF of grain crops is the highest of all products with a share of 44.21%. The increase in the local agricultural WF reached 53.18% from 2000 to 2019, but it was still lower than the amount of water available for agriculture. The evaluation results indicated that the region’s WF import dependency is lower than the global level, with an annual average self-sufficiency rate of 91.13% and an increase of 878.95% in the WF economic efficiency index. The agricultural WF produced in Hotan is exported in the form of trade, but the quantitative contribution is small and does little to relieve water stress in other regions. The agricultural water consumption was still within the range of local water resources that could be carried but only 6 years of sustainable water use, and the future development was not optimistic. With the ratio of produced WF to available water resources maintained at about 58%, the local available water resources should be above 43.21 × 108 m3 to initially ensure the sustainable use of water resources. There were 12 drought years in the study period, which are prone to droughts and high disaster levels. The drought-water scarcity systems behaved in three phases: 2000–2011 (uncoordinated level), 2012–2015 (transitional phase), and 2016–2019 (coordinated level). Water scarcity threatened by drought reduced. The occurrence of meteorological droughts was more related to natural factors while the changes in WF were mainly driven by socio-economic elements such as human activities.

Use of condensed water from air conditioning equipment as a strategy to face the global scarcity of freshwater: a review

The increase in the world's demand for water has become one of the most relevant topics on environmental sustainability and the conservation of water resources. As a result of the scarcity of potable water, processes such as the use of water through practices, techniques, and technologies for its efficient use have become essential for future generations. Among the possibilities for using water, air conditioning systems stand out, due to the formation of condensed water during operation. The world's population is increasingly concerned about environmental issues, showing that it is necessary to seek alternatives to recycle water, whether for use in gardening, sewage systems, washing sidewalks, and cars, among others. The present study carried out a literature review to reflect on the theme of the reuse of condensation water from air conditioners as a strategy for the sustainable use of water resources and enhancing the future of planet Earth.
