“…The need for holistic multi-dimensional assessment of water-scarcity and an integration of multi-stakeholder perspectives into the development is growing. Implementation and optimization of water management measures have been widely acknowledged in theory but not achieved in practice (Damkjaer and Taylor, 2017;Hussain et al, 2022). Masterplans and mitigation strategies reviewed in our case studies aim, at a minimum, to reach a holistic approach (Lahnsteiner and Lempert, 2007;EPA, 2016;Carroll, 2017).…”

“…Today's assessment of water scarcity still does not reflect its multi-layered nature and focuses mainly on population, availability and use of water (Liu et al, 2017). Often missing are a holistic analysis of environmental flows to conserve functioning of aquatic ecosystems; an adequate inclusion of water quality indicators such as concentrations of pollutants, green and virtual water flows at the global level; and the temporal variations of all water system components (Liu et al, 2017;Hussain et al, 2022). A transdisciplinary approach including environmental, socioeconomic and governance dimension of water scarcity is crucial to develop sustainable mitigation strategies (Jerneck et al, 2011;Damkjaer and Taylor, 2017).…”

Water scarcity is one of the main challenges facing countries in arid or semi-arid zones. As an example, Egypt needs to deal with both insufficient quantity and quality of water for residents. Here, we propose actions and policies to promote an integrated water management approach to respond to water challenges in Egypt. Based on a literature review, we have selected a set of criteria concerning the environmental, economic, social, governmental, and physical dimensions of urban water management. We studied approaches from Peru, Namibia, and South Australia as these countries have similar climatic conditions and water issues and have made substantial advances toward sustainable water management. Key criteria are state or municipal ownership of water and related infrastructure, agreement on master plans for sustainable water management, improvement of water sanitation and overall infrastructure, and reduction of water demand. Participatory, and educational campaigns put water issues at the center of public debates. We evaluated which elements of water management approaches can be adapted and used in Egypt, which faces limited freshwater resources, and which faces a highly increasing population. Proposed actions included directing water fees to ecosystem projects, treatment of wastewater to be potable, participatory approaches that engage the community in water management, educational campaigns that lead to change of public perception and knowledge dissemination. We interviewed key stakeholders in the water sector in Egypt to validate our proposed approaches. The stakeholders supported knowledge dissemination, suggested using water fees in implementing environmental projects and criticized converting wastewater into drinking water. Finally, we drafted specific recommendations at the organizational and urban levels of water management. We recommended establishing a General Organization for Water Management to oversee water-related organizations and ministries. We also recommended prioritizing the economic conditions to support alleviation of water subsidy, increasing public awareness, and creating a public database for water knowledge. In addition, we recommended decentralized water management and water sensitive urban design. The value of these approaches is their applicability, with minor adaptations, to countries with similar or close climatic and socio-economic conditions to Egypt, such as the MENA region.

“…Water scarcity is considered as one of the most impactful global challenges for human society as nearly 3.8 to 4 billion people around the world experience some form of water crisis annually. 1,2 Seawater desalination is one of the solutions to this problem as about 97% of Earth's water is in oceans. However, desalinating seawater requires a large amount of energy, which leads to the burning of fossil fuels and causing harm to the environment.…”

“…Increasing urbanization, industrialization, population growth and unavoidable climate change cause the demand for drinking water to increase constantly 1 . Freshwater resources for water supply are constantly decreasing, and although we are demonstrating more and more conscious and pro-ecological attitudes in terms of water saving, studies show significant water scarcity of water globally and locally, especially in countries with dry climate 2 . Forecasting water demand over different time horizons is crucial in the management of water resources.…”

Modern solutions in water distribution systems are based on monitoring the quality and quantity of drinking water. Identifying the volume of water consumption is the main element of the tools embedded in water demand forecasting (WDF) systems. The crucial element in forecasting is the influence of random factors on the identification of water consumption, which includes, among others, weather conditions and anthropogenic aspects. The paper proposes an approach to forecasting water demand based on a linear regression model combined with evolutionary strategies to extract weekly seasonality and presents its results. A comparison is made between the author's model and solutions such as Support Vector Regression (SVR), Multilayer Perceptron (MLP), and Random Forest (RF). The implemented daily forecasting procedure allowed to minimize the MAPE error to even less than 2% for water consumption at the water supply zone level, that is the District Metered Area (DMA). The conducted research may be implemented as a component of WDF systems in water companies, especially at the stage of data preprocessing with the main goal of improving short-term water demand forecasting.
