Abstract:
The installation of water efficient appliances is an efficient demand-side water management measure favored by policymakers and water providers nowadays. The adoption of low flow showerheads in large and complex plumbing systems will not only contribute to a great reduction of shower water use in the whole water system, but also further influence the water supply system design. Hence, it is necessary to justify the redesign of existing water supply systems (such as the pipe size, storage tank volume, pumping arrangement etc.) in terms of the use of low flow showerheads.

Inefficiencies in water supply systems are a critical challenge in many developing regions, including Babati District, Tanzania. Despite efforts to improve water access, issues such as inadequate government funding, inconsistent development aid, limited community involvement, water leakage, and high energy costs hinder the efficient operation of these systems. These inefficiencies compromise service delivery, leading to unreliable access to clean water and heightened operational costs.

The inductor current sensing circuit accurately tracks the output current of the switching converter that switches up to 30MHz.

Abstract:
AbstractAs the world’s population grows, the demands for increased food production expand, and as the stresses on resources such as land, water and nutrients become ever greater, there is an urgent need to find alternative, sustainable and reliable methods to provide this food. The current strategies for supplying more produce are neither ecologically sound nor address the issues of the circular economy of reducing waste whilst meeting the WHO’s Millennium Development Goals of eradicating hunger and poverty by 2015. Aquaponics, a technology that integrates aquaculture and hydroponics, provides part of the solution. Although aquaponics has developed considerably over recent decades, there are a number of key issues that still need to be fully addressed, including the development of energy-efficient systems with optimized nutrient recycling and suitable pathogen controls. There is also a key issue of achieving profitability, which includes effective value chains and efficient supply chain management. Legislation, licensing and policy are also keys to the success of future aquaponics, as are the issues of education and research, which are discussed across this book.

Abstract:
Water supply systems represent key urban infrastructure that requires regular maintenance and rehabilitation to ensure efficient and reliable water delivery to the population. This paper provides an overview of the pipe rehabilitation processes in water supply systems, focusing on pipe condition assessment, selection of rehabilitation methods, and their effects. The importance of accurate assessment techniques is emphasized, followed by a review of various rehabilitation techniques commonly used, such as trenchless technologies, lining installation, and structural pipeline renewal.

Abstract:
Water losses are one of the key indicators of the efficiency of any water supply system. The paper describes how systems thinking can be used to create an efficiency management system. In doing so, the key components of the organization are: (i) culture, (ii) structure, and (iii) information. The paper is an attempt to transfer experience from a high-hazard industry to the field of water supply.

Abstract:
Uzbekistan's agriculture exhibits main three environmental challenges. These are inefficient irrigation systems that consume 90% of the national water supply and lose 40% of the water during delivery, production systems that account for 15% of the total greenhouse gas(GHG) emissions, and severe land and soil degradation. Uzbekistan has several 'green' agriculture policy measures. The agri-food development strategy for 2019-2030 and the strategy for the green economy transition by 2030 are few. Implementation of the measures is, however, slow. Green agriculture that enhances efficient water use

Abstract:
Heat pumps are an excellent solution to supply heating and cooling for indoor space conditioning and domestic hot water production. Conventional heat pumps are typically electrically driven and operate with a vapour-compression thermodynamic cycle of refrigerant fluid to transfer heat from a cold source to a warmer sink. This mature technology is cost-effective and achieves appreciable coefficients of performance (COP). The heat pump market demand is driven up by the urge to improve the energy efficiency of building heating systems coupled with the increase of global cooling needs for air-cond

Abstract:
Civil infrastructure systems—facilities that supply principal services, such as electricity, water, transportation, etc., to a community—are the backbone of modern society. These systems are frequently subject to multi-hazard events, such as earthquakes. The poor resiliency of these infrastructures results in many human casualties and significant economic losses every year. An outline of a holistic view that considers how different civil infrastructure systems operate independently and how they interact and communicate with each other is required to have a resilient infrastructure system.

Abstract:
As California advances its ambitious goals for transportation electrification to combat climate change, hydrogen-powered fuel cells are emerging as a viable solution for overcoming the challenges of heavy-duty vehicles, offering an efficient alternative to lithium-ion batteries because they produce minimal chemical, thermal, and carbon emissions. One type of hydrogen fuel cell technology called proton exchange membrane fuel cells (PEMFCs) has garnered the most attention due to its distinct advantages, including relatively low operating temperatures (60–80 °C) and reliable performance at high c

Abstract:
One of the key lessons of the 2007-2008 global financial crisis is the importance of financial market infrastructures (FMIs) as a pillar of financial stability. Before, the role of financial market infrastructures, namely the provision of trading, clearing, settling, recording, and compressing services for transactions between financial institutions (FIs) was often taken for granted. This was reflected in FMIs having often been referred to as the financial system’s plumbing, including by the Federal Reserve’s 14th chairman (Bernanke, 2011)—a clear reference to the critical yet concealed import

Abstract:
Nitrogen (N) plays a dual role in the agri-food system: it is an essential nutrient for all life forms, yet also an environmental pollutant causing a range of environmental and human health impacts. As the plant nutrient needed in greatest quantities, and as a building block of proteins and other biomolecules, N is a necessary part of all life. In the last century, an enormous increase of N turnover in the agri-food system has enabled increasing per-capita food supply for a growing world population, but as an unintended side effect, N pollution has increased to levels widely agreed in science

Abstract:
Addressing environmental challenges while improving social and economic conditions calls for innovative solutions. One of those challenges is the management of organic waste, which if left untreated can lead to water pollution, greenhouse gas emissions, and soil degradation. Brazil produces substantial amounts of organic waste due to its sizeable population and extensive agricultural production. As one of the largest economies in the Global South, the development of innovative solutions to organic waste management in Brazil can potentially pave the way for their adoption in other countries wit
