The Mann–Kendall test was used to identify potential trends, while the Pettit test was used to detect abrupt changes in rainfall, temperature, and streamflow. A set of three maps of LULC change (1990, 2003, and 2018) was developed to observe how they affect the hydrological pattern of the catchment. Statistical analyses were conducted at mean annual time scales to establish relationships among the anomalies. It has been noted that certain temperature gauges showed statistically significant increases in temperature. Change points in the 1980s and 1990s were identified during the study period. The annual streamflow trends displayed an increasing trend that was not that significant. LULC changes contributed to increased surface runoff, attributed to agricultural, settlement, and water body expansion, as well as reductions in bare land, forest, shrubland, and grassland. The MIKE SHE model performed well during both the calibration and validation periods on the monthly time scale. The alterations in LULC had a noticeable impact on stream flows during both wet and dry seasons, resulting in increased mean monthly stream flows during the wet season and decreased flows during the dry season. The MIKE SHE study and related statistical analysis is quite a different method to perceive the results.","PeriodicalId":285503,"journal":{"name":"World Water Policy","volume":" 16","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140692467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In modern era of high technology, artificial intelligence and the Internet of Things have an important role to play in decision‐making approaches. According to hydro‐agrological studies, an accurate assessment of evapotranspiration is necessary for irrigation control, and to have an in‐depth understanding of the environmental factor interactions, a sensitivity analysis should be carried out. One of the tools, alongside empirical equations, is artificial intelligence for time‐series prediction. Thus, we compared several models for Penman–Monteith ET0 estimation to see which one performs better in the arid area of Morocco using meteorological data from the region of Fes. They were evaluated according to the MSE, RMSE, MAE, MAPE, and R2 and the variance of error distribution to show the performances of linear regression, K‐Nearest Neighbor, decision tree, random forest, support vector regression, long short‐term memory, and artificial neural network. According to the findings, LSTM outperformed the models with satisfactory results and an accuracy rate of 99.82%. An underlying mechanism of sensitivity analysis was also introduced to find the contribution of each element and estimate the target with a limited dataset. The findings show satisfactory results of R2 = 98.97%. The distribution and reliability of the prediction were proven using the Taylor diagram and Kruskal–Wallis test for the effectiveness of the study. This research demonstrates the potential of employing data‐driven techniques for evapotranspiration estimation to improve the efficacy of water management strategies. This will help to address present issues and establish sustainable water practices in the face of changing environmental conditions.","PeriodicalId":285503,"journal":{"name":"World Water Policy","volume":"7 17","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140711948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, we found that 71.7% of participants had ever used an imported ceramic water filter in their households and the main reason given by these participants for abandoning or renewing these filters within their households was that they felt that they had already become old and inefficient.

Water safety plan (WSP) approach introduced by the World Health Organization (WHO) is recognized as the most reliable and effective way to manage drinking‐water supplies to secure public health. HCWW has adopted WSP as a holistic approach not only to mitigate the potential risk to public health but also as a participatory way to reinforce and create resiliency among the key actors in water sector. This study highlighted the tangible impacts on the performance and homogeneity of the water sector in different areas at different levels as a response of WSP implementation. Modifications have been recorded in the operational, institutional, collaboration, and legislative outcomes at micro‐level, meso‐level, and macro‐level as a response to WSP.

However, technological and management innovations are needed to make it feasible and effective. The main objective of this work is to evaluate the effect of irrigation with treated wastewater compared with fresh water on the growth of two ornamental plants: Rosa Sinensis hibiscus and Lantana Camara. The study also aimed to examine the impact of treated wastewater on the hydraulic performance of different irrigation systems. To carry out this study, irrigation was applied by two irrigation systems: subsurface drip irrigation and surface drip irrigation. Also, two sources of water were compared: treated wastewater from the WWTP of M'zar (tertiary treatment) and well water, each for a duration of 2 months. The results obtained showed that the treated wastewater generally promoted a better development of agronomic parameters such as height, number of branches, leaves, and flowers for both plants. The same observation was also made regarding the esthetical parameter. For the irrigation system effect, the results obtained showed a better development under the subsurface drip irrigation system; thus, the combination of treated wastewater and subsurface drip irrigation provided the best results for both plants. Regarding the hydraulic performance of the irrigation system, no risk of clogging of the distributors was observed in relation to the water quality; the uniformity coefficient and distribution uniformity remained above 90%. It can therefore be deduced that the use of treated wastewater for irrigation of green spaces should be at the heart of water resource mobilization policies. in fact, it represents an excellent alternative for promoting national water management strategies.","PeriodicalId":285503,"journal":{"name":"World Water Policy","volume":"4 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139602827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

That is why the issues of protection of this category of relations are relevant today in the legal plane. It is important to establish not only an effective mechanism for punishing the guilty but also for preventing the commission of criminal offenses against natural objects. The purpose of the study is to identify effective approaches for the prevention of crimes related to the use of water bodies. In the study, the methods of analysis and synthesis, comparison, deduction, generalization, formal legal, and abstraction were applied. As a result, it was possible to determine that the current state of water bodies in Kazakhstan is deteriorating, so they may be at a crisis level in the future. In view of this, the paper investigated the composition of a criminal offense related to the illegal use of water bodies. This made it possible to determine the current position of the legislator on the regulation of this issue in the legal dimension. In addition, the methods and tools that are used in Kazakhstan to prevent the spread of this type of criminal offense were established. Based on this, their shortcomings were analyzed, and proposals were developed to improve the process of preventing such crimes. Therefore, the place of environmental crimes in the modern criminal law doctrine was determined, and international experience in preventing such offenses was considered. The practical value of the findings is the possibility of using them to develop new national strategies and programs aimed at countering crimes in the field of water use.","PeriodicalId":285503,"journal":{"name":"World Water Policy","volume":"8 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139524613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Developing countries rarely include in‐stream water quality modeling in their strategic policy documents. In the sub‐Saharan regions, stream water quality is declining due to many human activities. Ethiopian is no different, and its environmental policy does not directly target the importance of impact and planning analyses. Also, it does not include decision making processes for the protection of water ecology and multiple water uses. In this study, stream water quality issues in the Awash Basin have been assessed. The key sources of land‐based pollutants have been identified, and the availability and appropriateness related data have been examined and evaluated as well as the capacity of model users of institutions. Applicable models with the capability of simulating the Awash streams are presented and the changes needed for the existing settings suggested. The model selection was undertaken using a set of criteria based on environmental assumptions to enable environmental improvement into the future. The available hydrological and monitoring information provides an opportunity to apply model analyses, while the poor capacity of the governmental model users is of concern. With limited supporting conditions in governmental water institutions, the level of in‐stream water quality modeling integration in the Awash Basin development plans is too low to make recommendations based on key areas of support. It is time to apply and capitalize on the potential opportunity of using the models in local, regional, and national institutions for planning and impact analyses and strategic policy documents. The methods described in this study can be a guidance for model practitioners of the Awash basin targeting improvement in their institutions.","PeriodicalId":285503,"journal":{"name":"World Water Policy","volume":"11 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139613793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
