“…Climate alterations lead to natural disasters and changes in natural conditions that make the development of natural resources more difficult. Increasingly, crowded cities are faced with limitations in the management of water distribution systems [3,6,7], which is currently aggravated by the pandemic caused by COVID-19, a virus that has had an impact on water [8,9]. A growing and substantial percentage of people live close to the coast or depend on the exploitation of the marine environment.…”

Water conservation is essential for any activity, as well as for the survival of both human and other living beings. It is commonly associated with access to clean water and sanitation, or even to unsustainable production and consumption, or sustainable cities and communities. However, there is increasing awareness of emerging issues related to water resources and their impact or relationship with other issues, such as climate change, access to food, health and well-being, or biodiversity (marine and terrestrial). Therefore, this study is aimed at understanding the perception of students of the Degrees in Early Childhood Education and Primary Education concerning water issues and their relationship Sustainable Development Goals (SDGs; number 2,3,6,11,12,13,14 and 15) in a coastal urban context. The study used a qualitative design, in which 59 student teachers were interviewed. The instrument was validated by 12 experts. The content analysis indicates that student teachers understand that there is an environmental problem in relation to water caused by human behaviour, and that its effects have an impact on other areas that are related to the SDGs included in the 2030 Agenda.

“…We recommend that the energy trajectories of future water supply portfolios be incorporated into the city's long-term planning to facilitate holistic decision-making in regards to electricity demand planning, drought resiliency considerations, and ecosystem protections. Synergistic opportunities in water and energy systems open new areas of innovative solutions such as improving the energy efficiency of operations, coordination of water pumping operations with water storage, resource recovery, on-site energy generation, technological innovations, and water trading schemes that could benefit both water and energy sectors, and could reduce the energy needs of water systems [45][46][47][48][49][50][51]. Future water systems should be designed based on holistic systems' paradigms that are multipurpose and integrative to promote reliability, resilience and sustainability for the city's urban water system.…”

Predicting the energy needs of future water systems is important for coordinating long-term energy and water management plans, as both systems are interrelated. We use the case study of the Los Angeles City’s Department of Water and Power (LADWP), located in a densely populated, environmentally progressive, and water-poor region, to highlight the trade-offs and tensions that can occur in balancing priorities related to reliable water supply, energy demand for water and greenhouse gas emissions. The city is on its path to achieving higher fractions of local water supplies through the expansion of conservation, water recycling and stormwater capture to replace supply from imported water. We analyze scenarios to simulate a set of future local water supply adoption pathways under average and dry weather conditions, across business as usual and decarbonized grid scenarios. Our results demonstrate that an aggressive local water supply expansion could impact the geospatial distribution of electricity demand for water services, which could place a greater burden on LADWP’s electricity system over the next two decades, although the total energy consumed for the utility’s water supply might not be significantly changed. A decomposition analysis of the major factors driving electricity demand suggests that in most scenarios, a structural change in LADWP’s portfolio of water supply sources affects the electricity demanded for water more than increases in population or water conservation.

“…Water infrastructures need to be resilient and must adapt to change, which in turn require an understanding of change drivers and (potentially compound) extremes (e.g., Luthy et al, 2020). Traditional and modern tools, ranging from sensors, embedded systems and Internet of Things (IoTs) to computational analytics, robotics and Artificial Intelligence (AI), must be brought to bear to develop and leverage scientific insights and engineering principles in a way that can inform policy.…”
