Self-Help Groups: Bridging the Gap for Financial Inclusion

Financial inclusion is very basic necessity in the economic progress of a country. But in most of the developing countries majority people are out of financial awareness ambit. Self -Help Group is one feasible way for the financial inclusion particular in rural area. Self – Help Group (SHG) is a small voluntary association of people, preferably from the same socio-economic background. They come together for the purpose of solving their common problems through self-help and mutual help. The SHG promotes small savings among its members. The savings are kept with a bank. This common fund is in the name of the SHG. Over the last two decades, in India, the Self-Help Groups have achieved many millstones. Various models and innovations, in terms of products and services, have emerged in the recent past in an attempt to achieve greater financial inclusion across the country. SHG are the key for enhancing the saving attitude among people of the country. Thus, no doubt, SHGs are primarily started to overcome financial problem of the neglected section of the society, today also, keeping the financing function as the first priority, SGHs help to boost financial inclusion. Further, the present study discloses that the SHGs members are empowered not only through micro financing activities but also by allied different initiatives. The study reveals that after joining the self-help groups, financial awareness improved and the socio- economic status of the members in the family and society are being increased day after day. Thus, to bring weaker and neglected sections of the society to main stream, self-help group can be one of the strong instruments.

Based on AHP, The Ecological Environment of Fenhe River Basin Is Evaluated

he evaluation of the ecological quality of the Fenhe River Basin is of great significance for the high-quality development of the Yellow River Basin and Shanxi Province. In this paper, the analytic hierarchy process (AHP) is used to evaluate the ecological environment of Fenhe River Basin. Firstly, based on the relevant research literature, the ecological environment evaluation index is determined, and the influencing factors of the evaluation index are determined. Secondly, the weight of different influencing factors is determined based on AHP method, and the weight of evaluation index is obtained. Finally, the ecological environment of Fenhe River Basin in different years was analyzed by weight analysis results and expert scoring method. The results show that the ecological environment evaluation indexes of Fenhe River Basin are : water loss, soil loss, water pollution and vegetation reduction; the influencing factors of the evaluation index are : rainfall factors, soil and water conservation measures, reservoir construction, industrial water use, coal mining, engineering construction, solid waste pollution, urban development, industrial structure change, population change; from 2000 to 2020, the ecological quality of the Fenhe River Basin continued to improve, indicating that the policies and measures adopted for ecological management were effective. The ecological deterioration near the main stream and tributaries of the middle and lower reaches of the Fenhe River is related to the pollution of mine environment and industrial sewage.

Remote Sensing Estimation of CDOM for Songhua River of China: Distributions and Implications

Rivers are crucial pathways for transporting organic carbon from land to ocean, playing a vital role in the global carbon cycle. Dissolved organic carbon (DOC) and chromophoric dissolved organic matter (CDOM) are major components of dissolved organic matter and have significant impacts on maintaining the stability of river ecosystems and driving the global carbon cycle. In this study, the in situ samples of aCDOM(355) and DOC collected along the main stream of the Songhua River were matched with Sentinel-2 imagery. Multiple linear regression and five machine learning models were used to analyze the data. Among these models, XGBoost demonstrated a superior, highly stable performance on the validation set (R2 = 0.85, RMSE = 0.71 m−1). The multiple linear regression results revealed a strong correlation between CDOM and DOC (R2 = 0.73), indicating that CDOM can be used to indirectly estimate DOC concentrations. Significant seasonal variations in the CDOM distribution in the Songhua River were observed: aCDOM(355) in spring (6.23 m−1) was higher than that in summer (5.3 m−1) and autumn (4.74 m−1). The aCDOM(355) values in major urban areas along the Songhua River were generally higher than those in non-urban areas. Using the predicted DOC values and annual flow data at the sites, the annual DOC flux in Harbin was calculated to be approximately 0.2275 Tg C/Yr. Additionally, the spatial variation in annual CDOM was influenced by both natural changes in the watershed and human activities. These findings are pivotal for a deeper understanding of the role of river systems in the global carbon cycle.

On the Advection–Diffusion Process With Developing Eddies in Karst Conduits

AbstractUnderstanding the fluid flow and solute transport in karst conduits is significant for preventing pollutants (treated as solutes) in karst areas. This study evaluates the evolution of eddies in semi‐circular rough conduits under different hydrodynamic conditions and their effects on solute transport. As inlet flow velocity increases, the non‐Fickian coefficient (a parameter used for qualifying the tailing of BTCs) increases first then decreases afterward. A critical equilibrium concentration is found when the concentration of the main flow stream and the concentration of the eddy zone reaches the same value, signaling the moment at which the mass transfer (due to diffusion) between the main flow stream and the eddy zone drops to zero. Such a critical equilibrium concentration and its corresponding moment of occurrence are found to follow two distinctive logarithmic functions of the inlet flow velocity. These findings provide crucial technical support for groundwater pollution control in karst areas.

Strategic marketing of sustainable fashion: exploring approaches and contradictions in the positioning of fashion rental

Despite the potential of sustainable fashion alternatives such as fashion rental, the market share of these business models is low, and they are considered niche offerings in the fashion market dominated by unsustainable options. However, limited research exists on the strategic marketing efforts required to position and scale these models. The aim of this study was to explore the strategic marketing of sustainable fashion by identifying approaches and contradictions in the positioning of fashion rental as a sustainable alternative. A qualitative multiple-case study was conducted involving five fashion rental companies in Finland. The findings were interpreted using Customer Value Propositions (CVPs) as a conceptual framework for exploring the economic, functional, emotional, and symbolic dimensions of proposed customer value as indicators for positioning. The study identified two approaches for positioning fashion rental: 1) in relation to ownership and 2) in relation to consumerism. These approaches revealed contradictions between detaching from and encouraging product ownership and balancing between maintaining and reducing consumerism. The results suggest that fashion rental companies navigate between niche and mainstream audiences by applying plasticity in their strategic marketing and that these activities occur within a highly complex environment. This article provides insights into the intermediate position of sustainable fashion alternatives, and expands the understanding of the gap between the acknowledged need to move to sustainable fashion and the minor share of these options on the market.

Hydrodynamic analysis of fish swimming behavior in turbulent river confluences

This study focuses on selecting the most appropriate turbulence model for simulating fish swimming behavior in river confluences. To achieve this, three numerical models—k-ε, k-ω, and large eddy simulation—were compared by running simulations under identical flow conditions and evaluating the results against biological experimental data. Among the models, the k-ω model demonstrated the smallest relative error, consistently within 5% of the experimental results, confirming its superior accuracy and reliability for this application. The k-ω model's ability to capture boundary layer turbulence and near-wall flow dynamics proved essential for studying fish swimming in complex turbulent environments. Simulations revealed that both the flow velocity ratio between the main stream and tributary and the confluence angle are critical factors influencing the flow structure. At higher flow velocity ratios (R = 1/3 and 3/1) or large confluence angles (α ≥ 90°), turbulence intensity increased, leading to more complex vortex formations that significantly impacted fish swimming speed. When the flow velocity ratio (R) is 1/3, the fish can achieve a maximum swimming speed of 2.75 L/s, which is significantly higher than the swimming speed of 1.18 L/s observed when R is 3/1. Additionally, fish closer to the center of the flow field experienced greater turbulence, resulting in higher energy expenditure. The findings provide crucial insights into the hydrodynamic mechanisms driving fish swimming behavior in dynamic aquatic environments.

Farmer Producer Organisations (FPOs) as Sustainable Transition Intermediaries: Insights from India

The scholarship on sustainability transitions has surprisingly few studies on agriculture and food systems, especially from emerging economies such as India. The role of firms and businesses, especially cooperatives and producer organisations in agri-food systems transitions, has not been explored as much. Over the past decade, many Farmer Producer Organisations (FPOs) have been formed, primarily focused on facilitating the supply of agro-chemical inputs, while offering limited support to farmers in transitioning towards ecologically sustainable agricultural practices. This study looks at four case studies FPOs from across geographies in India, providing an opportunity to look at these FPOs as intermediaries of sustainable transitions and how they situate themselves in the agricultural ecosystem that has mainstream market actors as well as FPOs that are not engaged in sustainable agriculture. Additionally, to understand the intermediary role of FPOs, it is essential to examine how key actors—such as civil society organizations, financial institutions, marketing partners, and government agencies—contribute to and influence the intermediary role of FPOs in sustainable transition. These FPOs that are engaged in and promote sustainable agricultural practices bring out their strong potential transition intermediaries of the future.

Refinement and Validation of the SPEcies at Risk Index for Metals (SPEARmetal Index) for Assessing Ecological Impacts of Metal Contamination in the Nakdong River, South Korea

The SPEcies At Risk index for metals (SPEARmetal index) was refined using updated physiological sensitivity data and validated to assess the ecological impact of metal contamination on benthic macroinvertebrate communities in the upper Nakdong River, near a Zn smelter in Korea. Biosurvey and chemical monitoring data were collected at 18 sites surrounding the smelter and nearby mines. Acute ecotoxicity tests on 20 indigenous species from the Korean peninsula were conducted and used to update taxon-specific metal sensitivity data. The refined SPEARmetal index, based on this updated sensitivity, was significantly lower than previous versions, with most values below the severe impact threshold (0.5) in the main stream. The correlation between hazard quotients in water and the SPEAR index improved, with the correlation coefficient increasing from 0.63 to 0.70. Despite consistently high benthic macroinvertebrate indices (BMIs) across the study area, generic ecological indices, such as total richness, EPT (Ephemeroptera, Plecoptera, and Trichoptera taxa richness), and Shannon’s diversity index, showed correlations with metal contamination levels. Principal component analysis identified the SPEARmetal index as the primary indicator associated with metal contamination in both water and sediment. These findings highlight the improved performance of the refined SPEARmetal index as a more sensitive and specific tool for assessing the ecological status of metal-impacted aquatic ecosystems compared to traditional indices.

Monitoring Dissolved Organic Carbon Concentration and Flux in the Qiantang Riverine System Using Sentinel-2 Satellite Images

Real-time monitoring of riverine-dissolved organic carbon (DOC) and its controlling factors is critical for formulating strategies regarding the river basin and marginal seas pollution prevention and control. In this study, we established a linear regression formulation that relates the permanganate index (CODMn) to the DOC concentration based on in situ measurements collected on five field surveys in 2023–2024. This regression formulation was used on a large number of data collected from automatic monitoring stations in the Qiantang River area to construct a daily quasi-in situ database of DOC concentration. By combining the quasi-in situ DOC data and Sentinel-2 measurements, an enhanced algorithm for empirical DOC estimation was developed (R2 = 0.66) using the extreme gradient boosting (XGBoost) method and its spatial and temporal variations in the Qiantang River were analyzed from 2016 to 2023. Spatially, the main stream of the Qiantang River exhibited an overall decreasing and increasing trend influenced by population density, economic development, and pollutant discharge in the basin area, and the temporal distribution of DOC was controlled by meteorological conditions. The DOC contents had the highest in summer, primarily due to high rainfall and leaching. The inter-annual variation in DOC concentration was influenced by the total annual runoff volumes, with a minimum level of 2.24 mg L−1 in 2023 and a maximum level of 2.45 mg L−1 in 2019. The monthly DOC fluxes ranged from 6.3 to 13.8 × 104 t, with the highest values coinciding with the maximum river discharge volumes in June and July. The DOC levels in the Qiantang River remained relatively high in recent years (2016–2023). This study enables the concerned stakeholders and researchers to better understand carbon transportation and its dynamics in the Qiantang River and its coastal areas.

PIV experimental study on dynamic and static interference flow field of multi-operating centrifugal pump under the influence of impeller wake

In order to study the influence law of the impeller wake on dynamic and static interference flow field of the centrifugal pump, this paper obtains the dynamic and static interference flow field of the centrifugal pump under different flow conditions (15 m3/h, 50 m3/h, 70 m3/h) based on PIV technology, and analyzes the influence mechanism of the impeller wake change on dynamic and static interference flow field. The results show that rotating stall occurs in the centrifugal pump under low flow condition, but it has little effect on the head loss in the centrifugal pump. In the dynamic and static interference flow field, under the condition of the low flow rate, the impeller wake collides with the baffle tongue, resulting in serious velocity fluctuation, and then there will be the secondary collision with the volute wall, which will eventually cause the wake to dissipate, and the change process of the wake shows the periodic characteristic. In the design condition and the large flow condition, the spacer tongue will have the cutting effect on the wake, and the high-speed accumulation phenomenon will occur in the volute flow path near the spacer tongue. In the side flow path of the volute, under the condition of the low flow, the impeller wake is mainly located at the exit of the impeller, and the end of the impeller wake is easy to fall off and gradually break up under the impact of the main stream. Under the design condition, the flow stability is good, and the wake vortex is close to the trailing edge of the blade, and there is no obvious shedding phenomenon. Under the condition of the large flow rate, the velocity fluctuates sharply, and many large-scale vortex structures appear on the cross section of the flow channel due to the cutting of the wake near the diaphragm tongue. In the impeller passage, the movement and distribution of the wake are significantly affected by changes in flow conditions. The research results provide a basis for optimizing volute channel.

Exploring administrative evil, the ethics of dissent, and guerrilla government in The Good Place

This article uses the comedy television series The Good Place as a starting point to theoretically explore the value of guerrilla government as a measure to disrupt administrative evil. Drawing from the literature of administrative evil and Rosemary O’Leary’s work on the ethics of dissent and guerrilla government, this article considers the personal ethics and organizational cultural motivations for dissent as well as how administrators work to disrupt administrative evil while navigating through various strategies including loyalty, neglect, voice, and exit. This article demonstrates how popular media can be used as a means of theorizing for public administration scholars as well as a space where ideas related to public administration can apply existing theories in a method that can be engaging to mainstream audiences. The paper concludes with a proposed model of how administrative evil and guerrilla government may be conceptualized to interact with one another as well as potential areas of opportunity for administrators to practice dissent within the broader maze of bureaucracy administrative evil can become lost amongst.

Occurrence, spatiotemporal distribution, and health risk of antibiotics in the Wuhan section of the Yangtze River, China.

The occurrence, spatiotemporal changes, and health hazard of antibiotics in source water and finished water in the Wuhan section of the Yangtze River are not well understood. In this study, 43 source water and finished water samples were collected from 11 water plants in Wuhan in August 2021 and May 2022. Fifty-one antibiotics from eight categories were measured. A total of 41 antibiotics were detected in the source water samples, and 24 in the finished water samples. The total antibiotic concentration in source water ranged from 1.68 to 437.18 ng/L, which is significantly higher than that in finished water (2.04-87.25 ng/L). Sulfonamides and lincosamides were predominant, accounting for nearly 80% of the total antibiotic concentration. Lincomycin constituted nearly 30% of the total antibiotic concentration in the source water. In August 2021, the average total antibiotic concentration in source water was 107.12 ng/L, higher than in May 2022 (63.13 ng/L). Spatially, the total antibiotic concentrations in samples collected from the Han River, a tributary of the Yangtze River, were higher than those in the main stream of the Yangtze River. Ecological risk assessment indicated that the hazard posed by most antibiotics were negligible. Lincomycin potentially posed a high health hazard, and clarithromycin and roxithromycin posed a moderate hazard to infants.

Characteristics of dissolved organic matter in water bodies during the dry season in the Huainan section of the Huaihe River Basin in Northern Anhui Province, China

This study investigated the spatial heterogeneity of dissolved organic matter (DOM) composition and characteristics in the central reaches of the Huaihe River Basin. The dry season DOM content and composition of three river bodies (the main stream of Huaihe River, the Huaihe tributaries and agricultural drainage ditches) in the Huaihe River Basin were studied using UV-Vis and three-dimensional fluorescence spectroscopy combined with parallel factor analysis (EEMs-PARAFAC). The degree of DOM humification and the relative molecular weight of tributaries and agricultural drainage ditches were significantly higher than those of the main stream (p < 0.01), and regarding the autogenetic characteristics of the three types of water bodies the tributaries and drainage ditches were more strongly affected by exogenous interference than the main stream. Three kinds of chemical components were determined by PARAFAC mode(C1:terrsstrial humus-like;C2:tryptophan-like;C3:protein-like), protein-like components were the main fluorescent components in DOM during the dry season, the proportion of different water systems exceeds 50%. Principal component analysis (PCA) showed that the fluorescence intensity of humus was closely related to the TP(Total phosphorus) concentration in the Huainan section water body of the Huaihe River Basin during the dry season. The absolute principal component-multiple linear regression model showed that the contribution of water nutrition to the C2 and C3 of protein-like fluorescent components was greater, while exogenous interference had a greater effect on the TP physicochemical index.

Experimental study of flow boiling heat transfer in rectangular ribbed micro-channels with rectangular cavities

The flow boiling heat transfer in the RRM (i.e. ribbed micro-channel with aligned side-wall rectangular cavities), ORM (i.e. ribbed micro-channel with offset side-wall rectangular cavities), and ORMB (i.e. ribbed micro-channel with offset side-wall and bottom rectangular cavities) were experimentally investigated at a range of heat fluxes and mass fluxes. Combined with the visualization technology, the influences of offset rectangular cavities on the heat transfer and pressure drop penalty were revealed. The results showed that the existence of offset rectangular cavities enhances the heat transfer performance of micro-channels in both single-phase and two-phase regions. The bottom rectangular cavities in the ORMB enhances the disturbance to the main stream, thus further enhancing the heat transfer performance in the single-phase region and shifting from laminar to transitional flow earlier compared to the ORM. The capillary effect provided by the bottom cavities intensifies the heat transfer in the two-phase region, resulting in a significant increase in the critical heat flux in the ORMB. Compared to the ORM, the maximum increase of critical heat flux in the ORMB reaches 22.3 % (17.57 W·cm−2). The existence of offset rectangular cavities causes alternating resistance forces to the main stream, which increases the pressure drop in the ORM by 8–32.2 % compared to the RRM. The capillary effect provided by the bottom cavities to the liquid-phase in the ORMB is beneficial for the alleviation of vapor blockage and expansion. Hence the pressure drop in the ORMB is reduced by 82.3 % at most compared to the ORM in the two-phase region.

The evolution and disintegration of innovation narratives during scaling in science‐based ventures

AbstractScience‐based ventures (SBVs) are crucial vehicles that bring new technologies from the lab and to the mainstream market. During this journey, innovation narratives play a crucial role in coordinating innovation. Innovation narratives are linguistic representations that actors use to make sense of innovation activities, events and actions. In other words, they are stories that drive sensemaking, which is a critical element in avoiding conflicts in product innovation process and securing coordinated activities between diverse actors. However, as SBVs shift markets and undergo radical changes, they may have to update narratives to fit these changes. Yet, little is known about how innovation narratives and coordination evolve during this journey. To improve knowledge on this matter, I conducted a 24‐month study of a science‐based venture crossing over to a commercial market. I find that during this transition, innovation narratives shift from being shaped by progressive storytelling, where the benefits of becoming commercial and hiring nonacademics is highlighted, to being shaped by retrogressive storytelling, where incumbents and newcomers use their respective pasts to develop divergent narratives, and finally to appearing as disintegrated storytelling, where narratives compete and hinder coordination in innovation processes. Building on these findings, I construct a process model of how innovation narratives evolve and disintegrate as SBVs scale. This article contributes to knowledge on innovation management by illustrating how innovation narratives affect coordination in innovation processes, as well as how they may evolve during organizational change. Furthermore, this article illuminates the challenges that SBVs face to their innovation processes when scaling.

The impact of changes in water–sediment relationships at river confluences on the evolution of river bars

The confluence of tributaries and the main stream affects riverbed siltation and alters the upstream water–sediment relationships and flow structure of the main stream by adding additional flow. The relationship between these changes and the evolution of river bars, however, is yet to be fully understood. In this study, the areas of the river bars were extracted from Landsat image and analyzed using soft clustering to identify evolutionary patterns of the bars at the confluence of the Fen River (FR) and Yellow River (YR), and to analyze the hydrodynamic mechanism with hydrodynamic modeling. The results show that the spatial and temporal evolution of river bars in the study area over the past 50 years exhibits an evolutionary pattern, which exhibited evident clustering distributions and significant stage-based characteristics. This pertains to the water–sediment relationships as well as hydrodynamic fluctuations. At the confluence of FR and YR, the intensity of fluvial erosion experiences a mean increment of 9.67 %, while the incoming sediment coefficient witnesses a mean reduction of 5.74 %. The position of the confluence point exhibits a close association with the evolutionary characterized of spatial clustering and temporal phasing of the river bars. The river confluence area showcases a complex turbulence structure, wherein alterations in sediment transport capacity occur due to the influence of secondary flow and the topography of the confluence area. Consequently, this impacts the flushing of river sandbars and brings about modifications in siltation. Overall, this study provides the scientific basis for YR sediment management and channel modification in response to changing runoff and sediment conditions.

Deciphering the driving factors and probabilistic health risks of potentially toxic elements in arid surface water: Insights from the Tarim River Basin

Potentially toxic elements (PTEs) in surface water in arid areas pose a serious threat to environmental safety and human health within a basin. It is important to determine the factors controlling PTEs and to assess the likelihood that they will pose a risk to human health in order to support the development of environmental protection and risk management strategies. In this study, a structural equation model and Bayesian method were combined to discuss the distribution and probabilistic health risks of PTEs in surface water in arid area, and the Tarim River Basin was taken as a case study. The results show that the average concentrations of As, Co, Cu, and Ni in the surface water in the Tarim River Basin ranged from 0.04 to 2.92 μg/L, which do not exceed the international standard values. However, the maximum value of As (19.20 μg/L) exceeded both the recommended drinking water standards and the Chinese irrigation water standards. Spatially, the high As concentrations were distributed in the upper reaches of the Kashgar River, and the high Co, Cu and Ni concentrations were distributed in reservoirs and lakes on the main stream of the Tarim River. The concentrations of the PTEs in the surface water in the basin were not only affected by random anthropogenic factors such as traffic discharge, agricultural activities and mining industry, but were also directly and indirectly influenced by climatic factors. The results of the probabilistic health risk assessment showed that the 95th percentile the total hazard index for infants exceeded the allowable value of 1, and the total carcinogenic risk of PTEs exposure in four age groups was at the notable level. In this study, we conducted a comprehensive analysis of the controlling factors and health risks associated with PTEs in surface water in the Tarim River Basin, and the findings are expected to provide a scientific basis for regional water environment management and safety control.

Proactive policies are the key to reversing desertification in the main stream of the Tarim River in the past 30 years

The main stream of the Tarim River is a crucial part of China's ecological security strategy within the "two screens and three belts" framework, serving the "northern sand control belt" and the ecological civilization corridor. Evaluating and understanding desertification dynamics and driving factors is essential for achieving the United Nations Sustainable Development Goals and promoting ecological civilization. This study, based on the United Nations Convention to Combat Desertification, quantified the desertification process of the Tarim River's main stream from 1990 to 2020 using Landsat series satellite imagery from Google Earth Engine. Additionally, we employed panel data models to analyze the driving roles of climate change, socio-economic factors, and policies in desertification.Results indicate that between 1990 and 2020, desertification in the main stream of the Tarim River initially intensified, with 15% of the area experiencing desertification between 1990 and 2000. However, this trend was subsequently reversed, with only 0.6% of the area undergoing desertification over the 30-year period. Extensive economic development (−37.2%) and population growth (−48.7%) were the predominant factors exacerbating desertification in the initial period (1990–2000), whereas positive policies (55.3%) were the key to reversing desertification in the main stream of the Tarim River over the past 30 years.We also explored whether policies necessarily play a positive role in combating and preventing desertification. Based on this, we suggest actively engaging in interdisciplinary research and linking research outcomes with practical situations to formulate scientifically sound policies and measures for desertification prevention and control.

Study of the Dynamic Adaptive Calculation Method for River Water Environmental Capacity

Controlling the total amount of river pollutant discharge is an important means of water resource protection and management, and it is also a necessary condition for ensuring the normal functioning of water areas. The total amount of pollutant discharge is closely related to the water environmental capacity (WEC). Shifting from the traditional method of calculating WEC to dynamic analyses and calculations, concerning practical applications, in this paper, a dynamic adaptive calculation method is proposed for the river WEC that considers the changes in adaptive demand and hydrological conditions. In this method, the dynamic WEC is represented by intervals based on dynamic changes in different spatial and temporal scales, various calculation methods, hydrological conditions, and parameters. According to the calculation results for the WEC, a variable interval was formed. Taking the Shaanxi section of the main stream of the Wei River as the research object, with the support of an integrated platform, the dynamic adaptive calculation of the WEC in the Shaanxi section of the Wei River was realized, and a corresponding simulation system was constructed. The verification results show that (1) the dynamic calculation of WEC can be realized by freely combining different model methods and calculation conditions; (2) the WEC is described using a variable interval, which has strong applicability and operability; and (3) the simulation system can quickly adapt to the changing needs of practical applications and provide managers with visual and credible decision support. The research results provide a theoretical basis for river water environment pollution prevention and environmental management decision-making and help in the high-quality development of the river basin.
