ANALISIS HUKUM PEMANFAATAN SUMBER DAYA AIR UNTUK KEBUTUHAN RUMAH PENDUDUK DALAM PERSPEKTIF KESEJAHTERAAN

Water is a natural resource that is very important in everyday life. Some of the benefits of water resources in daily life include irrigation in agriculture, electricity generation, and household activities. The problem that arises is whether the regulation and use of water resources is in accordance with the needs of residents' homes, and how are sanctions applied for misuse of water resources that are not in accordance with the intended needs of residents' homes? The aim of this research is to find out and analyze the use of water resources for residents' housing needs, and to provide alternative solutions to the application of sanctions for misuse of water resources that are not in accordance with the intended use of residents' housing needs. The research method used is normative juridical, with a legislative approach as primary legal material combined with observation and observation as secondary legal material, especially a welfare perspective. results: That the use of water resources for daily needs is not yet optimal, even though there have been several statutory regulations, therefore the implementation of water quality protection and management should be carried out through a process of planning, utilization, control and maintenance, so that the need for water resources for people's homes are filled. That the alternative solution is to enforce the law firmly and clearly and strictly supervise perpetrators who commit violations against the use of water resources for the needs of residents' homes.

Orderly and synergistic development of urban-rural integration based on evolutionary game model: A case study in the Jiangxi Province, China

The orderly synergy is crucial to the integrated development of urban and rural areas in China. The orderly synergistic development process can be regarded as a game of balancing the interests of rural and urban areas. Therefore, numerical simulations with scenario analysis using the evolutionary game approach are conducted to investigate the orderly synergistic development of urban-rural integration. The results show that: (1) The values of orderly synergistic benefits of urban-rural integration are negatively correlated with the Nash equilibrium values at the municipal and provincial levels. (2) The orderly synergistic benefits of policy and market environments have different strategic choices and behavioral constraints for both urban and rural areas. (3) The benefits of “market-oriented” urban-rural choices are greater than those of “policy-oriented” directions. At the municipal level, the main factors influencing the choice of a “market-oriented” direction are the increased benefits of water resources, land resources, rural population mobility, and urban innovation factors. while at the provincial level, all factors lead to urban-rural trends in a “policy-oriented” direction.

Coal mine closure substantially increases terrestrial water storage in China

The transition away from coal involves the widespread closure of coal mines. While the potential adverse consequences of these closures on industry and the local economy have received considerable attention, empirical evidence on the benefits of water resources remains limited. Here, we quantify the effect of coal mine closure on terrestrial water storage (TWS) in China using satellite data and a staggered difference-in-differences approach. Our findings indicate a rapid restoration in TWS following closure, with coal mine closures increasing TWS by an average of 18.8 ± 8.9 mm per year. This increase in TWS is primarily attributable to augmented groundwater storage and reduced industrial water usage. Furthermore, our analysis suggests that these TWS gains exceed the indirect impacts of climate change mitigation efforts on water resources, potentially complementing such strategies in water-stressed regions. Overall, our study underscores the positive environmental impact of coal mine closures on water availability in China, potentially facilitating the transition away from coal production and enhancing the sustainability of the energy transition.

The role of water resources in tourism development in Halsho district

Water is considered one of the most important requirements of life and is the source of life. It has been given an important place in the map and policies of states in today's world. Water is also an important tool for policy, economic, and demographic mapping. There is no doubt that the water consumption center will develop in the future and the population's demand for water will increase. With the development of civilization, industry, and modern life, water plays an important role in the emergence and development of the most important economic activity of the population today. This study is dedicated to identifying the impact between water resources and tourism activities in Halsho district. The importance of this research is that it presents the relationship and impact of water resources on tourism activities in a scientific and detailed manner through the use of several maps to illustrate the relationship between this natural resource and tourism activities. The main objectives of this research are to highlight the role of water resources in how to develop tourism and to discuss a new and modern mechanism for further benefits of water resources in Halsho district. This research consists of three main parts: the first is about water resources in the sub-district, which discusses the surface and groundwater resources of the study area; the second part is about the concept of development, and its types and principles for tourism in Halsho Sub-district are presented.

Finally, several suggestions and recommendations are presented in order to develop the tourism sector in Halsho sub-district.

Optimization of agricultural planting structure in irrigation areas of Heilongjiang province considering the constraints of water resource system resilience

From the perspective of sustainable development in irrigation areas, imperfect constraints, which have negatively impacted previous agricultural planting structure optimization models, tend to produce unreasonable optimization results. Thus, in this paper, attempts are made to incorporate the resilience of water resource systems into the constraint set and explore the optimal layout of agricultural planting structures in irrigation areas. We selected 12 sample irrigation areas in Heilongjiang Province, China, including Chahayang, Fuyu, and Tailai, as the research areas and considered their actual situations. Then, we established a multiobjective optimization model for an agricultural planting structure with rice, soybean, and corn planting areas as decision variables; socioeconomic benefits, agricultural production benefits, ecological benefits, and water resource benefits as objective functions; and water resource system resilience and net crop output value and other factors as constraints. Fifteen scenarios were assessed through the combination of objective functions, and the nondominated sorting genetic algorithm III (NSGA-III) was used to optimize and analyze the agricultural planting structure of typical irrigation areas in Heilongjiang Province and to determine the optimal planting plan. The research results found that the function values adjusted by planting area have significantly improved compared to those before optimization. The adjustment trend of agricultural planting area is to increase the planting area of rice and soybean and reduce the planting area of corn. The introduction of constraints on water resource system resilience ensures that other benefits remain basically unchanged; thus, the water resource objective function is significantly better with resilience constraints than without them. Therefore, water resource system resilience can act as an effective constraint; this finding enriches and expands the theoretical and methodological system for optimizing the management of agricultural planting structures in irrigation areas and thus provides important technological support for ensuring regional food security, ecological security, and water security, which has substantial practical significance.

Economic benefits of water resources based on input–output model

Abstract To relieve environmental stress on water resources and promote stable socio-economic development, this article combined input–output models to analyze water resource utilization and development and to classify economic benefits. Based on this, an in-depth study was conducted on the economic benefits of water resources. Taking Hubei Province as an example, from the perspective of industrial structure, an empirical analysis was conducted on the water use benefits of various industries through input–output of water resources. The results showed that the mechanical industry and the transportation industry had the highest relative output coefficients, reaching 12.17 and 15.21, respectively. According to the results, the economic benefits of water resources in the secondary and tertiary industries of Hubei Province were relatively ideal. In practical development, industry-leading advantages could be utilized to optimize water resources management, innovate water use models and technologies, promote the improvement of agricultural water utilization rate and thus promote sustainable development of water resources.

Construction of a rural water environment management system from the perspective of ecocivilization

Abstract The ecological protection of rural water resources is not only related to people's living environment, but also affects their drinking water safety. Currently, the water environment in rural areas is severely polluted and lacks an effective management system. To improve the effectiveness and efficiency of rural water environment management and to improve the development of rural water resources, this paper conducts in-depth research and exploration on the construction of a rural water environment management system from the perspective of ecological civilization. This article first analyzes the causes, impacts, and current situation of rural water resource pollution. Then, from the perspective of ecological civilization, it analyzes the necessity of building a rural water environment management system, and explores measures to reform the rural water environment management system with the goal of maximizing water resource benefits. To verify the effectiveness of the management system, this article conducted comparative experiments on the construction of water environment management systems from three perspectives: water quality, water pollution level, and water resource utilization rate. The results show that compared with before construction, the water resource utilization rate after establishing a management system has increased by 32.4%.

Integration of Managed Aquifer Recharge into the Water Supply System in the Algarve Region, Portugal

The Algarve region of Portugal is experiencing severe water scarcity with existing water supplies insufficient to meet demand, with limited resilience to drought. Managed aquifer recharge (MAR) can provide intermediate storage and bridge the gap between water availability and demand, with success depending on the water available and the aquifer capacity to accept and store the water. We present the results of a regional study quantifying both these aspects to estimate the regional potential for MAR. Our results demonstrate that MAR can comprise 10% of the total water demand of the region (24 Mm3/yr) using water that is not otherwise captured, with quality that meets the requirements of the Groundwater Directive. MAR can replace 15 Mm3/yr of surface water used in the public irrigation perimeters and 9 Mm3/yr can be used to develop and maintain a strategic groundwater resource in the aquifers of the Central Algarve. Although climate change is predicted to result in an 8–13% decrease in MAR recharge, this can be addressed by incrementally increasing MAR design capacity. MAR has similar water resource benefits to the planned major infrastructure projects (desalination and River Guadiana abstraction), with reduced environmental impacts and lower costs than almost all feasible alternatives. We conclude that MAR is an important measure to increase water supply security and drought resilience in the Algarve region.

A Full-Scale Optimization of a Crop Spatial Planting Structure and its Associated Effects

Driven by the concept of agricultural sustainable development, crop planting structure optimization (CPSO) has become an effective measure to reduce regional crop water demand, ensure food security, and protect the environment. However, traditional optimization of crop planting structures often ignores the impact on regional food supply–demand relations and interprovincial food trading. Therefore, using a system analysis concept and taking virtual water output as the connecting point, this study proposes a theoretical CPSO framework based on a multi-aspect and full-scale evaluation index system. To this end, a water footprint (WF) simulation module denoted as soil and water assessment tool–water footprint (SWAT-WF) is constructed to simulate the amount and components of regional crop WFs. A multi-objective spatial CPSO model with the objectives of maximizing the regional economic water productivity (EWP), minimizing the blue water dependency (BWFrate), and minimizing the grey water footprint (GWFgrey) is established to achieve an optimal planting layout. Considering various benefits, a full-scale evaluation index system based on region, province, and country scales is constructed. Through an entropy weight technique for order preference by similarity to an ideal solution (TOPSIS) comprehensive evaluation model, the optimal plan is selected from a variety of CPSO plans. The proposed framework is then verified through a case study of the upper–middle reaches of the Heihe River Basin in Gansu province, China. By combining the theory of virtual water trading with system analysis, the optimal planting structure is found. While sacrificing reasonable regional economic benefits, the optimization of the planting structure significantly improves the regional water resource benefits and ecological benefits at different scales.

The Bumiayu people already have local wisdom in choosing temples that are adapted to environmental conditions.

Canal water distribution optimization model based on water supply conditions

The optimization of canal water distribution is vital in irrigation areas because a reasonable distribution is required to improve the water distribution efficiency and maximize the benefits of water resources. In this paper, under the condition that the total volume and flow rate of water supply in the primary canal have been determined, the water supply is compared with crop water demand, and three optimal models of canal water distribution are established. In situation 1, the total volume of water supply is sufficient to meet the crop water demand during the growing period. In situation 2, the water supply is insufficient to meet crop water demand during their growth period; however, this problem is resolved by extending the water supply period. In situation 3, the water supply cannot meet the crop water demands during the growth period, even after adjusting the water supply period. Because the proposed water distribution optimization model is based on water supply conditions in irrigation areas, the irrigation area managers can easily develop their operation water distribution schemes. The model was validated using the Bojili irrigation area. Results showed that the model’s calculated variation trend of the main-canal flow rate was similar to the actual flow rate, and irrigation area managers could meet the model requirements with a small adjustment in the actual flow rate. The model also considered canal leakage loss, timely water distribution, water distribution fairness, and other goals, potentially improving agricultural water efficiency and water distribution satisfaction as well as promoting sustainable agricultural development. The model presented here is universal and can be used in other irrigation areas.

Optimization and Benefit Analysis of Grain Trade in Belt and Road Countries.

Grain trade in Belt and Road (B&R) countries shows a mismatch between the volume and direction of grain flows and actual demand. With economic and industrial development, the water crisis has intensified, which poses a great challenge to the security of world grain supply and demand. There are few studies on the reconstruction of grain trade relations from the perspective of grain economic value. In this paper, a linear optimization model considering opportunity cost is proposed to fill the gap, and it is compared and analyzed with the optimization model considering only transportation cost. The grain supply and demand structures in both optimization results show characteristics of geographical proximity and long-tail distribution. Furthermore, the economic and water resource benefits resulting from the two optimal configurations are compared and analyzed. It is found that the economic benefits generated by grain trade in B&R countries with the consideration of opportunity cost not only cover transportation costs but also generate an economic value of about 130 trillion US dollars. Therefore, considering opportunity cost in grain trade is of great significance for strengthening cooperation and promoting the economic development of countries under the B&R framework. In terms of resource benefits, the grain trade with consideration of opportunity cost saves nearly 28 billion cubic meters of water, or about 5% of the total virtual water flow. However, about 72 billion cubic meters of water is lost for the grain trade with consideration of transportation cost. This study will help to formulate and adjust policies related to the "Belt and Road Initiative" (B&R Initiative), so as to maximize the economic benefits while optimizing the structure of grain trade and alleviating water scarcity pressures.

Analysis on competition strategy and regulatory strategy of international river water resources system – with the participation of co-operational agencies

Abstract In order to reasonably allocate water resources, meet the water demand of water users, and solve the frequent conflicts of water resources in international rivers, this paper explores the optimal regulation strategy of water resources with the participation of co-operational agency based on game model. Our results show that: for water users, the regulatory strategy of co-operational agencies affects the competition of water users, and the competition strategies among water users also affect each other. The economic benefits of water resources, water withdrawal costs, fine and honor value all affect the water resources competition strategy of water users. For co-operational agencies, the competition strategy of water users affects the regulatory strategy of co-operational agencies. The intensity of penalization and the regulatory cost have an impact on the regulatory strategy of co-operational agencies, but the amount of operation funds of co-operational agencies does not affect its regulatory strategy. The research shows the water resources game process of international rivers with the participation of co-operational agencies, and provides some insights for the water resources regulation of international rivers.

Variation characteristics of high flows and their responses to climate change in permafrost regions on the Qinghai-Tibet Plateau, China

River flow characteristics in permafrost regions on the Qinghai-Tibet Plateau (QTP) have changed rapidly with the intensification of global warming. However, the specific change characteristics and their responses to changes in influencing factors remain unclear. Based on the multi-year flow data of several typical basins in the QTP permafrost regions, combined with the flow duration curve and percentile flow, this study analyzed the variability of annual peak discharge, Q5, Q10, and Q30 (5%, 10%, and 30% percentile flows in the flow duration curve, respectively) and their response relationships with different climate change factors. In addition, the corresponding relationships between different percentile high flows and annual hydrographs were analyzed. The results indicate that, in the context of global warming, changes in the high flows in permafrost regions are bidirectional, either rising or falling, or both. Moreover, the responses of different percentile high flows to climate change are seasonally distinct. Spring high flows are more sensitive to changes in air temperature and normalized difference vegetation index (NDVI), and summer and autumn high flows are more susceptible to corresponding changes in seasonal average precipitation and rainfall intensity. In addition, different percentile high flows can be used to predetermine the level of annual flood events. Among them, the largest, the larger, and all other general flood events during the annual flood season, can be defined by Q5, Q10, and Q30, respectively. The analysis of different high flows combined with the flow duration curve is essential for the further clarification of the hydrological processes in permafrost regions. The prudent utilization of water resources benefits the sustainable development of human society.

A decision support tool for measuring and tracking the social benefits of water resources in Michigan coastal communities

This Research Study was conducted to demonstrate and measure social wellbeing in Michigan coastal communities resulting from investments in local water-related projects and resource development that can lead to community vibrancy and to provide a model for communities throughout Michigan and the Great Lakes Basin. The primary goal of the study was to develop and implement an online Community Vibrancy Dashboard that would assist planners, decision makers, business leaders, and residents in defining, reviewing, and tracking community vibrancy. The study was supported by the Michigan Office of the Great Lakes under the 2016 Michigan Water Strategy and funded through the Great Lakes Restoration Initiative.Four coastal communities in Michigan – Alpena, Manistee, Port Huron, and Sault Ste. Marie – participated in the study. These communities were selected because of their long economic and cultural histories with the Great Lakes, all are similar in size, and all have conducted relatively recent water-related resource restoration projects and were willing to participate.This study demonstrates how community engagement can result in measurable social indicators of community vibrancy that focus on the use of and connectedness to water resources in the Great Lakes Region. The study resulted in an innovative online visualization toolkit that provides opportunities for public review of local water projects and their resultant contributions to community vibrancy. The Community Vibrancy Dashboard provides timely and visible feedback to local leaders, planners, and decision makers on past and future projects and a means of tracking progress in meeting community vibrancy goals.

An ecological interval two-stage fuzzy shadow price model for environmental flow allocation in the Shaying River Basin

Abstract In recent years, social water is pressurizing ecological water, causing the environmental flow to not be guaranteed and destroying the ecological environment. This research aims to coordinate social and natural water use to bring about optimal economic benefits, while ensuring environmental flow requirements. In this study, an interval two-stage fuzzy shadow price model (ITS-SPM) has been developed, which combines two-stage programming (TSP) and system of water value to optimize environmental flow. The ITS-SPM is mainly characterized as system benefits constituted by expected water resource benefits and water shortage penalty. This model has removed the uncertainties of economic data and environmental water demand (expressed fuzzy and interval). It has been found that adjusting the social water structure can effectively solve the problem of insufficient ecological flow. The ITS-SPM can make the adjustment of social water use more reasonable, which will produce benefits, unlike the current agricultural water reduction policy. Under the premise of guaranteeing optimal economic benefits, the added value of environmental water use in different scenarios is (social water structure adjustment) as follows: in 2020, it was expected that Shaying River water would increase by at least 13.49%; in 2025, it is expected to increase by at least 33.35%; in 2030, the increase will be by at least 57.54%; and in 2035, it will be by at least 77.50%.

Sustainable regional water allocation under water-energy nexus: A chance-constrained possibilistic mean-variance multi-objective programming

It is important to manage water resources under water-energy nexus considering both steady economic development and environmental needs. In this study, a water resources management modelling framework of regional water use sectors was established by combining the water resources value theory with the uncertainty theory. The water resources value of different water use sectors was calculated through Cobb-Douglas (C-D) production function and emergy theory to estimate the benefits of water resources accurately. On this basis, a chance-constrained possibilistic mean-variance multi-objective programming (CPMMP) model was established by integrating the classical mean-variance model based on investment portfolio, chance-constrained programming (CCP), possibilistic mean and variance of fuzzy number with multi-objective programming framework. This model can not only deal with the risks of inaccurate water-supply prediction and the fluctuating water supply benefits but also achieve compromise resources consumption, and environmental protection under uncertainty. Taking Shiyang River Basin as an example, the validity of the proposed framework and solution method were verified under different hydrological years, 60%WSB (best water supply benefits) and 90%WSB scenarios. The calculated average water resources value in agricultural, industrial and domestic were 1.92, 109.67 and 20.71 CNY/m3 respectively, and the standard deviation were 0.21, 15.68, 2.60 CNY/m3 respectively. The variability of water resources value in industrial sector were far greater than those in agricultural and domestic sectors. These fluctuations of water resources should be paid attention to in the water resources allocation. The established CPMMP model can effectively reduce the system risks, net carbon emissions and energy consumption under the premise that the system benefits are equivalent to the status quo. Optimal results can provide decision makers energy-saving and emission-reducing water resource management strategies, which are conducive to the sustainable development of the system. Besides, the established framework can also provide a scientific basis and technical support for other resource management in other regions.

ПРОГНОЗИРОВАНИЕ ЧРЕЗВЫЧАЙНОЙ СИТУАЦИИ НА ГИДРОТЕХНИЧЕСКИХ СООРУЖЕНИЯХ

The article deals with the actual problem of emergencies at hydraulic structures. Since time immemorial, man has continuously developed various methods and techniques to take advantage of the benefits of water resources, as well as to protect himself from the ravages of water. Thus, on the territory of the Republic of Tatarstan, a large number of hydraulic structures were erected, which are classified as hydrodynamic hazardous facilities. Accidents at these facilities are sources of man-made emergencies. A number of hydraulic structures on the territory have been in operation without reconstruction for more than 70 years, and most of them are in disrepair. The problem of ensuring the safety of hydraulic structures remains not fully understood and relevant today. As a rule, basically all hydraulic structures are located within or above settlements and are objects of increased risk, since the destruction of dams can lead to an environmental disaster. Also, incomplete destruction of the dam, when the safe operation of the structure is no longer possible, can lead to serious economic losses as a result of the cessation of energy production, hydraulic regulation and water collection in the reservoir. Therefore, careful monitoring is required to identify any possible emergencies. One of the solutions in this situation is the use of various methods for predicting emergencies at hydraulic structures. In this regard, in the work, the authors adapted a mathematical model based on Markov chains, which is distinguished by the efficiency of calculations and a high degree of approximation to statistical data. This model makes it possible to predict the state of hydraulic structures when the data on the water level and the volume of seepage in the hydraulic structure changes. Based on the adapted model, the results of forecasting the water level for real hydraulic structures were obtained.

Building check dams systems to achieve water resource efficiency: modelling to maximize water and ecosystem conservation benefits

Abstract Among the most widespread structures for successfully retaining water and checking erosion on the semi-arid portions of China's Loess Plateau, check dams retain silt at slower than projected rates, leading to flood control issues. Meanwhile, the shortage and the uneven distribution of time and space of water resources in semi-arid areas can easily cause droughts and floods, which seriously restricted the rapid development of the socioeconomic. However, some of the high-quality rain and flood resources accumulated in the check dams can be used to alleviate part of the water resources crisis instead of causing flood. With the goal of holistically maximizing a projected check dam array's water resource, ecosystem and socioeconomic benefits, a Check Dam Benefit Maximization Model (CDBMM) was first developed. The CDBMM was first applied to the Si Jiagou Basin, and the model showed the total costs represent 7.07% of the total and rather significant benefits. Water resources benefits accounting for 45.40% of the total benefits, indicating that the water resources benefits were substantial and should be considered as the main influencing factors in the basin's ecosystem-friendly design and construction. Use of the CDBMM in watershed planning will allow a more efficient use of water and soil resources and greatly alleviate water crises in the semi-arid area. It can further provide a reference for both check dam system planning and the system benefits analysis.
