The increasing water demand, the prolonged drought periods and the human influence in natural resources that put in danger the quantity and quality of water resources, highlight the importance for rational management and exploitation of water resources in terms of sustainable development of an area. The purpose of this study is the application of procedures for sustainable management and development of the water resources of the Grevenitis basin, using Geographic Information Systems (GIS) technology. Grevenitis drainage basin is part of the greater Aliakmon river drainage basin (NW Greece). It’s located in the central section of Mesohellenic Trough. The study reveals the capability of itself-reliance of the area of Grevenitis basin in covering the total water needs and the new perspectives for sustainable development of the area with the exploitation of the surface waters of Grevenitis river and the groundwater of the aquifer formed in the Plio-Pleistocene sediments, which overlay on the impermeable molassic sediments. It’s also shown the important contribution of GIS technology with the creation of databases for the continuous monitoring of the various parameters with their changes and the convenience for direct drawing of thematic maps. The evaluation of quality parameters of drinking water brings to light useful results and recommendations in order to assist and improve current water quality monitoring and protective actions.

Abstract. Nowadays, the increasing pressure over water resources is reflecting on the water quality all over the globe. Not surprisingly, local, and regional governments are taking initiatives into tackling this issue. However, the management of water resources requires coordinated management by the stakeholders, especially in cross-border regions, to achieve efficient regulations. Then, the data-sharing for monitoring the water resources is fundamental for the stakeholder participation in the process of knowledge building. This work presents the design and implementation of a collaborative web platform aiming at enhancing these processes applied to share water quality parameters maps produced under the framework of the SIMILE (Integrated monitoring system for knowledge, protection and valorisation of the subalpine lakes and their ecosystems) project. The platform takes advantage of open-source infrastructure and standards. The solution provides two web-based applications devoted to the upload/management (customized GeoNode) of the data and its visualization (WebGIS). The scope of the collaborative platform is to improve the access to information for awareness-building on the water resources in the Insubric area.

The purpose of this article is to study the processes of water quality management, which are considered as the main factor of the strategic social and economic development of the region and also to form tools supporting this process. The article analyzes the state and development trends of the water sector of the Rostov region from the standpoint of solving the problems of its strategic social and economic development. The authors demonstrate the possibility of intellectualization of regional strategizing processes through the use of water quality monitoring of the knowledge of experts with the use of fuzzy logic. The review of existing approaches to the assessment of water resources quality is given. It is shown that these approaches do not take into account the different requirements of water users to the content of chemicals and compounds in the water but assess the state of water resources in terms of conformity of concentration indices of polluting substances to maximally allowable concentrations. The authors suggest assessing the quality of water resources in compliance with the criteria of the contamination of water resources set for every category of water users. The approach proposed by the authors implies the assessment of water quality in two modes – differentiated and complex. Meanwhile, the suggested tools are universal and can be used in the systems of regional strategizing of the use of various water basins. A conceptual representation of the structure of the management system of water resources quality in the region within the system of regional strategizing is formed and the main problems of its development are identified.

Abstract This study demonstrates and analyses spatio-temporal changes and trends of 15 water quality parameters that were arbitrated from the samples collected at 11 sampling locations during the water quality monitoring across the Dal Lake from September 2017 to August 2020. Further a revised WQI (named WQImin) was developed contingent on multiple regression modeling comprising six key parameters (NH4-N, DO, COD, WT, TUB and NO3-N) so as to ease the course of action and lessen the systematic costs of the water quality assessment. The results signify that the general mean WQI value 81.9 and seasonal average WQI values ranges from 79.44 to 84.55. The quality of water showed seasonal variance, with lowest values in summer, succeeded by autumn and winter, and highest in spring. Moreover, the suggested WQImin model contingent on the selected six critical parameters displayed execution in the evaluation of Dal Lake’s water quality with R2 = 0.99, RMSE value (5.48) and PE value of 6.34%. This manifested that the developed WQImin model can be convenient and efficacious implement to control and determine Dal Lake’s water quality. Further results showed that most of the nutrients were above the threshold value during the monitoring period, which is the leading cause of eutrophication at some places in the lake.

Ecosystem vulnerability increases significantly when anthropogenic factors overlap with the effects of adverse climate change, which together negatively affect biodiversity and ecosystem functioning. According to ADB forecasts, the inflow to the lower reaches of the Amu Darya will decrease by 26-35% by 2050. The combined effect of higher water demand and lower inflow will increase the current water shortage - the annual water shortage will increase to 50% of the total demand. In connection with the projected changes, the current state of water resources of the Amu Darya river, as well as the need for the socioeconomic development of the region, the task of assessing the projected impact of climate change on the availability and quality of water resources becomes urgent.

Among the Sustainable Development Goals (SDGs) established in the 2030 Agenda, goals 6.3, regarding clean water and improve of water quality, and 6.5, regarding integrated water resources management, highlight the need for the implementation of successful environmental water quality monitoring programs of transboundary river waterbodies. In the present study, the designation of high priority areas for water quality monitoring of Drin transboundary watershed is performed using a suitability model, a GIS-based multicriteria decision analysis (GIS-MCDA) approach that takes into consideration the most important conditioning factors that impose pressures on rivers. Based on the results, the methodological approach used manages to sufficiently delimit the areas with increased need for water quality monitoring in the Drin watershed, and the validation procedure produces a correlation coefficient of 0.454 (statistically significant at a 0.01 level). Limitations arise in the case of a lack of detailed information or inaccurate input data and due to the inconsistency among the input data and the different methodological approaches regarding the information collection of each country involved. These restrictions foreground the need for cooperation between the countries involved regarding the exchange of scientific knowledge and common legislation, so as to achieve integrated, effective, and sustainable management of water resources of the area.

This study aims at developing the aspect of sustainable management of water resources in the part of the upper Euphrates basin to extend the year 2035 by using the Water Evaluation and Planning (WEAP) model. Water budget was developed to assess the current water conditions for the reference year 2015 based on available water supply and the increasing demand for water uses. Some of the proposed scenarios have been applied to the WEAP model. The results showed that the total water demand in 2015 was 100 MCM, and it will rise to 400 MCM in 2035. With the emergence of a water deficit, it is expected that 38 MCM, will be fully provided by applying modern irrigation methods. However, when applying the wastewater reuse scenario, it was found that the water deficit reaches 35 MCM. On the other hand, the water deficit has been approximately decreased to 16 MCM when the groundwater scenario was used as an additional source of water supply. The results confirmed the necessity of adopting alternative methods to reduce the water deficit, as well as the ability of the WEAP model to represent the study area.

Rapid economic development has posed pressure on water resources, and the potential for a water crisis has become an important obstacle to the sustainable development of society. Water footprint theory and its applications in agriculture provide an important strategic basis for the rational utilization and sustainable development of water resources. Based on the monthly meteorological observations and agricultural data of Shandong Province, CROPWAT 8.0 and Geographic Information System (GIS) technology, the green, blue and grey water footprints of wheat, maize, cotton and groundnut from 1989 to 2016 were calculated and the spatial variations of water footprints for crops in different rainfall years were analyzed. Additionally, assessment of water stress for agricultural productions was conducted in this study. The results showed that the average water footprints of wheat, maize, cotton and groundnut were 2.02 m3/kg, 1.24 m3/kg, 7.29 m3/kg and 1.75 m3/kg, respectively in Shandong Province. A large amount of the average total water footprint was calculated for wheat (420.59 × 108 m3/yr), maize (222.16 × 108 m3/yr), cotton (72.70 × 108 m3/yr) and groundnut (50.07 × 108 m3/yr). The average total water footprint of the four crops was 765.52 × 108 m3/yr (29.98% blue) and exhibited a gradual decreasing trend over time. Specifically, the total water footprint of wheat was the highest among four main crops in Shandong Province and exhibited a decreasing trend during 1989–2016. The maize was ranked in the second place, and was the only crop still increasing rapidly. The spatial and temporal changes of water footprints for crops were obvious in different rainfall years. Additionally, agricultural productions in most regions were facing the threat of water scarcity. Therefore, the scientific planning of crop planting structures and rational control of sown areas of crops with large water footprints should be implemented in severely water-scarce regions. This study can give some suggestions on the adjustment of planting structure for the sustainable development of agriculture and the realization of efficient utilization of water resources.

According to the IPCC (2014), access to water resources is increasingly limited due to the effects of climate change; in consequence, vulnerability of ecosystems and their inhabitants increases. Thus, it is necessary to develop socio-organizational capacities to mitigate and adapt to this scenario, where retribution mechanisms for ecosystem services (MRSE for its Spanish acronym) become more relevant. The research attempts to analyze the coordination among agents involved in sustainable water resources management, to face climate change vulnerability in high biodiversity areas. For this purpose, the implementation of the Quiroz-Chira water fund will be studied as a case that generates institutionalism for sustainability of this mechanism and that represents an important social innovation that can be replicated. The methodology has a descriptive scope and applies qualitative techniques that complement secondary sources systematized with WebQDA software. Results indicate high vulnerability of the analyzed basin districts and a correct governance in this innovation, both with a sustainable development approach oriented to conservation of water potential. This implies good articulation for implementation of the MRSE and promotion of interests’ unification between contributors and water resources retributive entities.
