Calculation of the SPI, SPEI, and GRDI Indices for Historical Climatic Data from Doñana National Park: Forecasting Climatic Series (2030–2059) Using Two Climatic Scenarios RCP 4.5 and RCP 8.5 by IPCC

In this study, we utilized three different indices to assess drought conditions in the Doñana National Park (DNP) located in southern Spain. These indices included the Standardized Precipitation Index (SPI), which is based on precipitation statistics, the Standardized Precipitation Evapotranspiration Index (SPEI), which incorporates both precipitation and air temperature data, and the Groundwater Recharge Drought Index (GRDI), a newly developed index specifically designed to evaluate groundwater drought. The analysis covered the time period from 1985 to 2015, and future projections were made for the years 2030–2060 under different climate scenarios (RCP 4.5 and RCP 8.5). Our findings revealed a significant decrease in total precipitation of approximately 13–14% compared to historical records (1985–2015). Moreover, severely to extremely wet periods exhibited a reduction ranging from 25% to 38%. A key contribution of this study is the application of the GRDI index, which allowed us to assess groundwater recharge rates. We observed a decline in the simulated mean recharge rates during the 21st century when compared to the historical period spanning from 1950 to 2009. This decline can be attributed to increased evapotranspiration. The results of this research provide valuable insights for the Spanish water resources administration. The observed reductions in precipitation and groundwater recharge rates emphasize the need for appropriate mitigation measures. The findings will aid the administration in formulating an integrated water resources management strategy in the Doñana National Park and its surrounding basin. By understanding the projected changes in drought conditions, the administration can make informed decisions to ensure sustainable water resource management in the region.

Quantifying future water and energy security in the source area of the western route of China’s South-to-North water diversion project within the context of climatic and societal changes

Study regionYalong River Basin (YLRB), China. Study focusThe YLRB was selected to investigate the impacts of climatic and societal changes on water and energy security in the water-diverting area of China’s South-to-North water diversion project (SNWD-W). The future runoff and hydropower generation were projected using Watergap hydrological model (WGHM) under different Representative Concentration Pathway (RCP) scenarios and water withdrawals were predicted based on the shared socio-economic pathways (SSPs). New hydrological insights for the regionThe results show that the future runoff and hydropower generation in the YLRB display significant increasing and decreasing trends under RCP8.5 and RCP2.6, respectively. The water stress index (WSI) is projected to increase by about 30%, but it is still lower than 0.2 even combined with the SNWD-W project. The future hydropower generation is projected to change by − 0.87–4.75% and 0.44–6.10% under RCP2.6 and RCP8.5 without water diversion, respectively. The slight increment caused by climate change cannot offset the substantial decrement caused by water diversion, especially in the maximum transfer amount scenario, which highlights the tradeoffs between the mitigation of water stress in the water-receiving area and the loss of hydropower generation in the water-diverting area. Our results provide a valuable reference for the water resources administration in the YLRB and the design of the water diversion scheme for the SNWD-W.

Evaluating future water security in the upper Yangtze River Basin under a changing environment

Water security is of great significance in social development, ecosystem sustainability, and environmental management. The Upper Yangtze River Basin (UYRB), which feeds more than 150 million people, is faced with aggravating water security risks due to more frequent hydrometeorological extremes and increasing human water withdrawals under a changing environment. Based on five RCP-SSP scenarios, this study systematically evaluated the spatiotemporal evolution patterns of water security in the UYRB under future climatic and societal changes. The future runoff was projected using Watergap global hydrological model (WGHM) under different Representative Concentration Pathway (RCP) scenarios and hydrological drought was further identified by the run theory. The water withdrawals were predicted based on the recently developed shared socio-economic pathways (SSPs). Then, a comprehensive risk index (CRI) for water security was proposed combining the degree of water stress and natural hydrological drought. The results show that the future annual average runoff across the UYRB is projected to increase, and hydrological drought tends to be more severe, especially in the upper and middle reaches. Dominated by water withdrawals in the industry sector, the future water stress in all sub-regions is estimated to increase substantially, with the largest change ratio of WSI in the middle future spatially ranging from 64.5 % to 301.5 % (66.0 % to 314.1 %) under RCP2.6 (RCP8.5). Based on the spatiotemporal variation of CRI, the UYRB is projected to face more severe comprehensive risks for water security in the middle and far future periods, and hotspot sub-regions are identified as Tuo River and Fu River, which are densely populated and economically prosperous, threatening regional sustainable social-economic development. These findings highlight the urgent need for adaptive countermeasures of water resources administration in response to more severe water security risks in the future UYRB.

Editorial Issue 1/2023: Water and Heritage in Action: Commitments for a Sustainable Future

Water awareness is inextricably linked to climate change awareness. In 1987, renowned climate scientist William W. Kellogg wrote an article about “the evolution of awareness” of humankind’s impact on the climate. He noted that over 150 years separated the first observations of this im- pact to the first explicit mention of the greenhouse effect in 1957 (Kellogg 1987). Over 35 years after Kellogg’s article, “awareness” is no longer the greatest challenge: it is “action.” The Water Conference of 1977 in Mar del Plata, Argentina, which aimed at establishing an international water resource management program, proposed an Action Plan to guarantee orderly administration of water resources as a key element for improving socio-economic conditions and quality of life for humankind (United Nations 1983). However, the plan did not result in widespread action and one reason was the broadness with which it was written. The 1977 Action Plan addressed countries generally, without considering specific climates, political structures, economic differences or so- cio-cultural contexts.&#x0D; Almost 50 years later and halfway into the Water Action Decade (2018–2028), progress on wa- ter-related goals and targets remains alarmingly off-track (United Nations 2023). The Water Action Agenda and the UN 2023 Water Conference promises a different approach and calls for commit-ments and actions. The president of the General Assembly remarked on the need for game chang- ers: methods, strategies, approaches and programs able to connect multiple disciplines, levels of governance and ways of thinking to enhance cooperation across actors, sectors and scales for sustainable development, beyond a “business as usual” approach (United Nations 2022).

Strategies to Increase Exports of Wine Companies of the Valle de Guadalupe Region in Baja California, México

This research analyzes the exports of wine companies in the Valle de Guadalupe region in the State of Baja California, Mexico. The objective is to determine the factors that induce strategic decision making to achieve a high-performance level of productive capacity. The hypothesis suggests that production, technological innovation, and competitiveness are the factors that favor the exports of these wine companies. For the statistical analysis, Partial Least Squares structural equation modeling (PLS-SEM) is used, including the evaluation of the out-of-sample predictive power by means of PLS predict. The methodology used includes a qualitative analysis of the current situation on the subject and a quantitative study of data obtained by applying a 41-item instrument to ninety-two companies. The main findings show that the variable that presents a higher degree of association is competitiveness and the variable that presents a lower degree is production. Another finding is that there is a need to strengthen collaborative projects with a Cluster Approach, in which the collaboration network between these companies, government agencies, wine associations and educational institutions must be actively involved. The main strategies proposed are three: the first in relation to competitiveness is to improve operational planning to increase productivity. The second is to achieve a more competitive price by purchasing supplies collaboratively between companies; the existing common bond and business cooperation will allow exports to increase. The third is to manage a greater participation of the government, in terms of financing and support, investment in highway infrastructure, reduction of taxes on this item and the sustainable administration of the State's water resources.

INVESTMENT DOMINANTS OF THE IMPLEMENTATION OF THE INNOVATIVE MODEL OF SUSTAINABLE USE OF FRESHWATER RESOURCES AT THE NATIONAL AND REGIONAL LEVELS

Of course, in addition to an effective system of control and administration of water resources, essential factors in the implementation of an innovative model of sustainable use of freshwater resources in the regions are the introduction of new technologies aimed at cleaning freshwater water bodies and promoting the rational use of water resources. The activation of such works requires sufficient funding and the attraction of additional investments in the industry. The article aims to research investment dominants in implementing an innovative model of sustainable use of freshwater resources at the national and regional levels. An analysis of investment support for developing the freshwater resource management system in Ukraine was carried out. The analysis showed that over the past ten years, the number of investments increased by 115%, which positively affected the state of water bodies and contributed to the reduction of water consumption in the economy. However, given the high level of wear and tear of the water management infrastructure, which according to the State Statistics Service, is an average of 63% of the available investments, it is not enough for the transition of water management to an innovative model of sustainable development. In addition, the conducted studies showed that more than 98% of investments are directed primarily to eliminating current problems in water management, reorganizing the industry, and partial modernization of water treatment facilities and centralized water supply systems. Almost no funds are invested in developing innovative activities in this area. The main areas of improvement of the system of investment support for innovative development of water management systems in the region are outlined, including improvement of regulatory and legal support and development of public-private partnership, in particular in the form of ESCO contracts; the use of freshwater resources for aquaculture production, which will increase the economic efficiency of the use of surface water bodies, will contribute to the attraction of investments in the industry and strengthening of food security; creation of conditions for attracting foreign investments, in particular in the construction and modernization of infrastructure; intensification of work in the direction of attracting international finances: grants, participation in international programs for the protection and restoration of water resources, etc.

Applying the participatory approach to assess the Water-Energy-Climate Change nexus in South Africa

ABSTRACT This paper uses a participatory approach to assess the level of understanding of the Water-Energy-Climate Change (WECC) nexus in South Africa. The aim is to initiate the development of well-coordinated, systematic, and holistic strategies to promote efficient management of the WECC and its implications in the country. The assessment follows the learnings from the Integrated Water Resource Management framework, which promotes a participatory approach in the administration of water resources. The paper reveals that, despite the reasonable level of understanding of WECC, it is still insufficient to promote an integrated approach mainly in policy development and planning for water and energy resources while averting climate impacts. This is exacerbated by limited coordination and consultation among various stakeholders. However, minimal efforts to promote an integrated approach in the management of the WECC sectors is observed. Despite these developments, the paper proposes that the participatory approach is feasible to promote holistic strategies and collaboration among stakeholders mandated to manage WECC sectors. Until approaches such as this are adopted within the institutional framework, this nexus will continue to impede the country's sustainable development endeavours.

Governance of the public Administration of water Resources and Services in the COVID-19 era

Water problems focused on scarcity, shortages, unhealthiness and high cost have been addressed from the social representations of users of the public drinking water service, although such studies have avoided the incidence of print media on readers. The objective of the present work was to specify a model for the study of the phenomenon, considering a review of press releases of national circulation during the period from 2015 to 2022, as well as the inclusion of frames in the disseminated information. A prevalence of the data was observed towards an intermediate frame of the problems, although the research design limited the results to the study scenario, suggesting the extension of the work to other scenarios such as the contamination of the aquifers and their effects on health Environmental public.

Evaluation of Six Satellite-Based Soil Moisture Products Based on in situ Measurements in Hunan Province, Central China

Long-term near-surface soil moisture (SM) data can be obtained on a regional scale through microwave remote sensing. Therefore, to quantitatively analyze the accuracy of multisource remote sensing–based observation products, improve the retrieval algorithm, and effectively use in terminal environments, a standardized comprehensive evaluation is imperative. The SM data obtained by the China Meteorological Administration and Ministry of Water Resources were used as reference data to verify the performance of six passive microwave remote sensing–based SM products from the SMOS, SMAP, GCOM-W, FY-3B, and FY-3C satellites in Hunan province, China. These data were also used to analyze the effects of topographical, land cover, and meteorological factors on SM retrieval accuracy. Results show that SMAP shows the best overall performance in Hunan province; furthermore, it exhibits stable accuracy and is not easily affected by environmental factors. The FY series of satellite products shows the worst performance, and some grid remote sensing data are negatively correlated with the ground measurement data. AMSR2 possesses the largest amount of data and the largest deviation, and only this product exhibits significant differences with the fluctuation trend of the measured SM and precipitation. Passive microwave detection technology presents the best performance in the central part of Hunan province and the largest bias in the Dongting Lake area. SMOS-L3 and SMOS-IC, two products of the same satellite, show the lowest bias but present differences in the SM fluctuation range, orbital accuracy, as well as dry or wet bias. Furthermore, FY-3B and FY-3C, two satellites belonging to the same series, exhibit excellent consistency in performance. The evaluation results and accuracy variation between products as well as other factors identified in the study provide a baseline reference for improving the retrieval algorithm. This study provides a quantitative basis for developing improved applications of passive microwave SM products.

Water Resources Management: Green Watershed Index (GWI)

A large number of indices and indicators of water performance at the basin level exist throughout the world, however, the need to generate tools that allow the monitoring of basins from their administration and water and environmental management, takes greater force in a global context where sustainability takes great importance. The GWI (green watershed index) methodology is presented, as an extension of urban control methodologies, but this time for rural watersheds. The method is implemented in some rural areas of Colombia, and in some cases the difficulty of implementing the methodology is evidenced, and in other cases the opportunity to improve the management and administration of water resources at the level of rural basins.

The strategic development for water loss prevention

The population growth and urbanization have gained importance in the Water Resource Management (WRM) works. The classic approach in relation to the development of the water resources has lost its sustainability. Water has, therefore, become an important, but also becoming a scarce natural source due to the global warming and its climate change impacts end results. The major aim of WRM is to increase the Water Distribution Network (WDN) to keep water supply sustenance by decreasing the water demand. The new approaches in relation to the WRM should take into consideration in a more refined manner the supply–demand balance with the improvements in the WDN. Recently, water resources performance improvements have become one of the significant investment topics in Turkey. However, data from the Turkish Statistical Institute and any academic research in this field have shown that there is a water loss of around 50% in the current water supply and distribution systems. In comparison to other developed countries, this loss is very high. It became, therefore, necessary that each Water Resources Administration should keep track on the costs, water leakage losses and the necessary technological investments. In the scope of this study, water loss levels reduction strategy possibilities are developed in the Sakarya City WDM system, Turkey. These strategies field applications have been presented in detail. Finally, the extent of accuracy in these strategies has been shown, which may provide guidance for other water administrations departments in the world.

El aporte de la ciencia ciudadana para generar un monitoreo visual de cianobacterias en el embalse Los Molinos, Córdoba, Argentina

Citizen science involves the participation of the entire community in scientific activities and promotes the active contribution of citizens in research projects through their efforts, knowledge, tools and resources. The community living nearby a reservoir suffers the main consequences of cyanobacteria blooms and usually has a popular knowledge of the problem and a great enthusiasm to collaborate in research tasks. This study describes a joint project between the community and the Faculty of Exact, Physical and Natural Sciences of the National University of Córdoba, the Special Rescue Group of Calamuchita and the Provincial Administration of Water Resources. This initiative includes the collaborative monitoring of cyanobacterial blooms in Los Molinos reservoir in an unprecedented experience in reservoirs in the province of Córdoba (Argentina). Secchi depth is described as an excellent indicator for recreational use. The participation of students of the Alfonsina Storni school in Potrero de Garay and of the Special Rescue Group of Calamuchita, who reported valuable data on the reservoir conditions in relation to cyanobacterial blooms and transmit the main results and conclusions to their families, coworkers and the whole community, is here underscored.

Towards Decision-Making for the Assessment and Prioritization of Green Projects: An Integration between System Dynamics and Participatory Modeling

This research article presents the integration of participatory modeling and system dynamics as a novel methodology for the consolidation of social dynamic models for the subsequent evaluation and prioritization of green projects in Colombian post-conflict communities. First, through participatory work carried out with a community, the citizen factors were identified, evaluated, and systematized in relation to the problems and needs of the region. Second, based on the results obtained, a simulation model based on system dynamics—which facilitates decision-making with regard to the evaluation of green projects—was calibrated. The proposed methodology lead to the conclusion that, with the participation of the community, and with a model based on the dynamics of the variables—such as supply and demand—for natural water and land resources, it is possible to warn decision-makers about variables that can lead to the maximization of investments, and thus to prioritize and select the most appropriate environmental, social, or economic initiatives that meet the needs or expectations of the involved community. In the future, the model could be used to facilitate the management, administration, and control of water and land resources by creating alerts called reserve margins.

Evolution and sustainability of groundwater use from the Ica aquifers for the most profitable agriculture in Peru

The Ica area of south-eastern Peru has evolved rapidly since the late 1990s into the most advanced agricultural development in the country. The intensive use of waterwells for year-round irrigation, primarily of asparagus, is the basis for an export industry worth about US$ 6,000 M/a, but one which is threatened by serious groundwater sustainability concerns. The public water-resource administration and private agricultural developers are beginning to confront the problem, which has already had a significant social cost, through developing measures to improve the groundwater balance whilst assuring agricultural production. This report presents the long-term evolution of land management and groundwater use in the area, and considers the feasibility of applying an adaptive and integrated water resources management (IWRM) approach to the system, with particular attention to managed aquifer recharge techniques.

Subject. The article discusses how the prevention of the negative impact of water can be improved as part of the public administration of water resources. We also focus on the methodological framework for preventing the adverse effect of water. Objectives. The study is to outline methodological guidance for prioritizing flood water/underwater zones so as to enhance actions governmental authorities undertake to prevent the adverse impact of water given the limited and untimely finance of such activities. Methods. The study is based on methods of systems and comparative analysis. Results. We devised the technique for quantifying the priority of flood zone projects, including three metrics, such as socio-economic, technical, hydrologic. The article sets forth methodological recommendations for calculating indicators used to prioritize the flood water/underwater zone projects when they are written in governmental programs of the region. Conclusions and Relevance. If the above methodological recommendations are put in practice, preventive measures will be more effective, budgetary spending will be optimized. This will reduce losses from effects of flood water in every municipal entity.

Assessment of extreme precipitation through climate change indices in Zacatecas, Mexico

Climate change and extreme climate events identified worldwide at the local, regional, and global scales have significant impact on ecosystems and on society. In this study, spatial and temporal changes in extreme precipitation events in north-central Mexico were investigated using daily precipitation data from 29 meteorological stations over a period of 54 years (1961–2014). The extreme precipitation events are described using ten of the indices established by the Expert Team on Climate Change Detection and Indices (ETCCDI), which characterize daily precipitation in terms of intensity, accumulation, and duration. The indices were calculated yearly and seasonally. The annual and seasonal trends of the indices were estimated with the Theil-Sen method, and its statistical significance was tested with the Mann-Kendall test (MK). The regional average indices of annual total precipitation from wet days (PRCPTOT), simple daily intensity (SDII), number of heavy precipitation days (R10), number of very heavy precipitation days (R20), and consecutive wet days (CWD) had downward trends, but only the last was statistically significant. The regional average of the indices of maximum 1-day precipitation (RX1day), maximum 5-day precipitation (RX5day), number of very wet days (R95p), number of extremely wet days (R99p), and number of consecutive dry days (CDD) showed upward trends, all statistically non-significant. The annual regional average PRCPTOT has decreased at a rate of − 6.20 mm/decade. The decrease was concentrated mainly in central and southern Zacatecas and is associated mainly with the decrease in autumn and summer precipitation. The annual regional average CDD index had increasing trends; 58.6% were statistically significant and concentrated mainly in central and southern Zacatecas. In terms of the general behavior of the PRCPTOT, RX1day, RX5day, R95p, R99p, CDD, and CWD indices, we observed that the precipitation events are decreasing but are becoming slightly more intense. The results will contribute to a better administration of water resources in the state of Zacatecas, Mexico, under the influence of climate change.

Geoecological problems of decentralization (on Ternopol region materials)

The objective of the article is to study the essential geoecological problems of Ukrainian associated territorial communities. The necessity of implementation of effective environmental management, through introduction of an official responsible for improvement, ecology and sustainable development of the associated territorial communities in the administrative apparatus of communities is substantiated.The decentralization reform created a considerable potential for development of the local communities. The transmission of significant financial resources and powers provided the preconditions for the formation of competent associated communities. It was discovered during the study that despite of significant advantages of new administrative units, managerial approaches to the use and preservation of natural resources had not changed. Administration of forest, water, mineral and land resources is further carried out from the center. Practically no one cares about the main ecological problems, communities are drowning in wastes, using water polluted municipal waste with agrochemicals, and the last hectares of forests are being cut down and used as energy resources. In context of sustainable development, the priority issues to be solved for 38% of the communities in Ternopil region are the issues of an ecological nature the issues of an economic nature are priority for 34% of communities and the issue of the social nature – of 28% of comminities. In Ternopil region, as in one of the leaders in decentralization reform, 78% of community leaders consider high-quality water supply to be much more important than availability of cooperative or lighting of the streets. The most actual in regional communities are issues concerning sorting and utilization of wastes, lack of treatment facilities and an outdated drainage system.The article proposes amendments to the Article 19 of the Law of Ukraine «On Environmental Protection», regarding the extension of powers of village, settlement, city councils as well as associated territorial communities in the field of Environmental protection. The necessity of introduction the position of ecologist responsible for improvement, ecology and sustainable development of the community is substantiated. His duties are the following: monitoring of components of the environment; struggle with the illegal landfills, regulation of processes of economical nature management; optimization of land use; control of rational water use, preparation of a submission for the creation of new protected objects of local importance; creation of recreational and green zones.

Evaluation of water quality state through regulations and physicochemical indicators for the administration of water resources in the Integrated Management District of Salto del Tequendama

Water resources are of great importance in the administration of protected areas. This is linked to the quality of surface water bodies that pro-vide different eco-systemic services, since they shelter different species of fauna and flora. In relation to Resolution 1596 of 2006 adopted by the General Direction of the CAR, which states the Management Plan for the Integrated Management District (DMI by its abbreviation in Spanish) in the area of Salto del Tequendama - Cerro Manjui, attached to the Water Cycle Management program and in relation with the "Water Quality Control" project, states the evaluation of the conditions of the different water sources in relation to water collection given by the communities as one of its objectives, and at the same time exposes the determinants of the conditions that take place in the surface water bodies. In this article, a correlation of the uses that are stated in the management plan will be performed in order to com-pare the results, which are obtained by means of the environmental monitoring that is evaluating the control and management of the "Water Quality Control". Based on the evaluation of water quality, it was possible to determine whether the uses that are defined in the Management Plan are appropriate, by linking them to the Water Quality Control program. Calculations were also made conducive to obtain indicators that would allow us to estimate the quality of the water and possible sources of pollution.
