Review of Literature
Issues to make Sustainable Water Management: The complicated nature of water systems, socioeconomic issues, and environmental factors provide some obstacles to the implementation of sustainable water management. The growing need for water worldwide due to urbanization, industry, and population expansion is one of the main challenges. Water supplies are under increasing strain, so finding smart ways to distribute, use, and preserve water is essential. Climate change is making water shortage worse, which is a serious problem that affects both quantity and quality. These difficulties are made worse by the unequal distribution of water supplies between regions and periods, which raises concerns about sufficiency and accessibility. In addition, inefficiencies and losses in the water supply chain are caused by insufficient infrastructure and wasteful water consumption. Water source pollution is another serious issue. Freshwater bodies are contaminated by industrial discharges, agricultural runoff, and inappropriate waste disposal, endangering human health and ecosystems. Sustainable water management has always faced the challenge of striking a balance between the requirement for environmental preservation and economic growth. Making decisions is made more difficult by the dynamics of stakeholders and conflicting interests. Managing competing priorities is necessary to maintain ecosystems while balancing the demands of people, industry, and agriculture. Overcoming this obstacle requires effective water governance, which entails comprehensive stakeholder participation and transparent decision-making. Climate change-related uncertainties pose a dynamic challenge. Variations in precipitation patterns, increased frequency and severity of floods or droughts, and temperature increases affect the distribution and accessibility of water resources. Strategies for adaptation need to be adaptable and sensitive to these shifting circumstances. It also costs a lot of money to implement sustainable water management in terms of infrastructure, technology, and education. Some areas, especially in poorer nations, struggle to implement cutting-edge water management techniques due to a lack of funding.
In conclusion, attaining sustainable water management necessitates a thorough comprehension of interrelated problems. It entails dealing with problems related to pollution, inequality in distribution, stakeholder disputes, scarcity, climatic uncertainty, and budgetary limitations. To overcome these obstacles and ensure future water security, creative problem-solving, teamwork, and a dedication to striking a balance between human needs and environmental stewardship are necessary.
The effects of climate change, population increase, and intense rivalry for water from the agricultural, industrial, municipal, and energy sectors are making water management increasingly difficult [1,2]. To achieve sustainable development, water demand and supply management is the main emphasis of integrated water resources management. One limited resource that is necessary for society to survive and operate is water. Because of this, implementing integrated water resources management is crucial to addressing shortages, the problems caused by climate change, and the rising water demand from growing economies [3]. A theoretical model that combined the views of integrated landscape management (ILM) and institutional design principles (IDP) was used to assess cooperative initiatives from wastewater from agriculture that involved water suppliers and agricultural stakeholders [4]. A nationwide evaluation of the danger of drought for agricultural areas was presented [5], accounting for the intricate interactions between many risk factors. According to studies, there are effective ways to improve agricultural water, including crop diversification, crop pattern management, and conjunctive (i.e., surface water and groundwater) water management [6].
Complex water demand and supply systems of today are managed by evaluation models that include social, economic, environmental, and climate variables. Using the idea of risk, a model was created by determining exposure, vulnerability, and hazards [7]. The vulnerability was divided into two categories: the human environment and the natural/built environment. The categories were sensitivity and adaptive capability. To manage water in agricultural regions, a geographic information system modelling and satellite data were created. The irrigation water demand was modulated based on many vegetation indices [8]. The water allocation regulations were assessed by water user groups in France [9], taking into account environmental, social, and economic, factors about water used by agricultural user groups. To evaluate the activities under various climatic scenarios, the Soil and Water Assessment Tool (SWAT) and the Adaptation Pathways methodology were combined [10].
Strong organizational strength is necessary for conjunctive management, and this may be attained through regional planning that is founded on a solid comprehension of how groundwater and surface water interact [11]. Strategic planning based on sustainable development principles is necessary for basins with established water supply and drainage networks to be sustainable [12]. The pursuit of sustainable growth satisfies the requirements of future generations while meeting existing economic, environmental, and social demands. It was mentioned [13] that there is a lack of strategic vision for sustainability objectives and actions. A SWOT analysis is a methodical strategic planning process that evaluates a system's strengths (S), weaknesses (W), opportunities (O), and threats (T) to determine its current state [14]. A SWOT analysis-based evaluation of the literature was published [15]. SWOT analysis was used to manage water resources strategically in Africa [16]. To assist the scalability and replication of watershed regional planning instruments in flood-prone areas, tactical planning techniques were investigated in Austrian food-risk management [17]. Prioritizing local and regional scale conservation efforts in diverse environments was made possible by the development of a raster-based regional preservation planning and action tool [18].
To enhance irrigation benefits in the setting of global water administration, a regionally dispersed crop water usage model, cellular automaton (CA), and crop suitability (CS) were implemented in a global optimization model of agricultural consumption of water [19]. Deficits in irrigation networks and corrective actions were identified through research that was published [20].
A subfield of research into operations called multi-criteria decision-making offers techniques for selecting options that are rated according to several criteria. In a variety of multi-criteria decision-making circumstances, the Analytic Hierarchy Process (AHP) is a commonly used decision-making technique [21]. This study uses the mean of the non-principal eigenvalue as an expression to define and quantify the consistency of the pairwise comparison matrix. Thorough a study and systematic classification of the literature on the techniques have been conducted [22]. A presentation [23] reviewed the TOPSIS approach to decision-making. To ascertain the criteria weights in decision-making situations, a novel step-wise weight assessment ratio analysis was presented [24]. The Decision-Making Trial and Evaluation Laboratory (DEMATEL) and the Best Worst Method (BWM) were two of the weighing techniques used in the decision-making process that were combined to accomplish the importance of supplier criteria [25]. Under uncertainty, a model combining the Additive Ratio Assessment (ARAS) approach was presented [26]. In a supplier selection challenge during the pandemic, a novel combinative distance-based assessment method and a categorical-based evaluation methodology were used to measure attractiveness, leading to the development of a new decision-making strategy [27]. The real score measures of the image fuzzy numbers were used to build the in a fuzzy environment [28]. To solve a real-world difficult decision-making problem in social science study, a unique modification of an established MCDM method referred to as the preference ranking based on the ideal-average separation approach in a fuzzy environment was used [29]. Three MCDM frameworks were used to compare the supply chain performance of top Indian healthcare firms [30]. The following lists the steps of the entropy approach [31-35] that were used to determine the criteria's weights.
An extended fuzzy lambda-tau and fuzzy MCDM approach was used to undertake an analysis of uncertainty [36]. Based on the additive ratio evaluation techniques and the removal of criteria, the integrated Fermatean fuzzy based on information decision-making approach was developed and applied to the problem of choosing a food waste treatment system [37]. Research was done on a fuzzy multi-criteria group decision-making model for managing ecological risk in watersheds [38]. Planning water for agriculture, food, energy, and crop area maintenance was made possible with the development of a scenario-based fuzzy interval programming technique [39]. Game theory was used to address issues with decision-making. Game theory may be used to help decision-making in a competitive context, as proven by the application of the technique to building site selection [40].
Issues for Making Sustainable Water Management
The primary concern in attaining sustainable water management pertains to the intricate and interrelated obstacles presented by population expansion, climatic variability, and the escalating requirement for water reserves. The pressure on water supplies brought on by urbanization and an increasing world population is one of the main problems. There is tremendous demand for water supplies due to rapid urban growth, which causes over-extraction from aquifers and depleting surface water resources. This problem is made worse by climate change, which also creates uncertainty in precipitation patterns, intensifies extreme weather events, and modifies the availability and timing of water supplies. The effect on hydrological cycles that follow is a major obstacle to sustainable water management. Pollution is yet another serious issue. Water quality is lowered by industrial discharges, agricultural runoff, and poor sanitation systems into water sources, which impacts ecosystems and public health. It becomes a difficult task to strike a balance between the need for environmental preservation and economic development. Unfair water distribution is a recurring problem where some areas struggle with a shortage of water while others deal with an overabundance of water that causes flooding. Planning strategically is necessary to address this mismatch, taking into account local and regional viewpoints.
The problem is made worse by antiquated water management techniques and ineffective infrastructure, which both lead to losses in the supply chain. Unskilled labour combined with outdated infrastructure makes it difficult to provide communities with clean water. Collaboration and effective governance are crucial components of sustainable water management that are frequently absent. The implementation of comprehensive and long-term remedies is impeded by inadequate regulation, enforcement, and cooperation among diverse parties. Finally, changing social attitudes and practices is necessary to ensure sustainable water management. Due to a lack of knowledge and instruction, practices including over-extraction, excessive water consumption, and inappropriate pollution disposal continue. To tackle these complex issues, a comprehensive strategy is essential. This entails implementing strong legislation, embracing nature-based solutions, integrating cutting-edge technologies, and encouraging community involvement. A paradigm change is necessary to achieve sustainable water management, where efficiency, equity of access, and conservation become essential elements of a broad and flexible approach.
