Water and sanitation

Water and sanitation are pivotal elements of the Sustainable Development Goals (SDGs), primarily encapsulated in SDG 6 (Clean Water and Sanitation). This goal seeks to ensure the availability and sustainable management of water and sanitation for all by 2030. This objective directly addresses the current global water crisis, where nearly 2.2 billion people live without access to safe water, and about 4.2 billion lack access to adequate sanitation.

By focusing on improving water quality, increasing water-use efficiency, implementing integrated water resources management at all levels, and protecting and restoring water-related ecosystems, SDG 6 addresses not only direct human needs but also the broader ecological health of the planet. Furthermore, efforts towards achieving SDG 6 indirectly promote several other SDGs.

For instance, water and sanitation are crucial to achieving SDG 3 (Good Health and Well-being), as clean water and proper sanitation facilities reduce the spread of water-borne diseases and significantly lower child and maternal mortality rates. Likewise, they are foundational to SDG 4 (Quality Education), given that the provision of water and sanitation facilities in schools significantly impacts the attendance and performance of students, particularly for girls.

SDG 2 (Zero Hunger) also intersects with water and sanitation, as sustainable and efficient water management is critical for agriculture, which remains the largest global water consumer. The necessity of water for food production and the potential impact of improved water management on crop yields and livestock health makes SDG 6 integral to achieving zero hunger.

SDG 6 contributes to SDG 1 (No Poverty) and SDG 8 (Decent Work and Economic Growth) as well. Access to clean water and sanitation can enhance economic productivity by reducing time spent gathering water, reducing healthcare costs due to water-related diseases, and even creating jobs in water and sanitation services sectors.

In terms of environmental impact, the sustainable management of water resources is essential for SDG 13 (Climate Action), as water is a key factor in managing climate change due to its role in agriculture and energy production.

This chapter aligns with UN SDG Goals 6 and 13 by discussing advanced water treatment technologies and promoting sustainable water management and climate adaptation strategies.
This study presents a deep learning framework using convolutional neural networks (CNNs) to efficiently replicate high-resolution outputs of conventional hydrological models for estimating groundwater head and surface water depth in the Sabgyo Stream Watershed, South Korea, achieving a 45-fold reduction in computation time compared to a physics-based model while demonstrating potential for predictive capabilities under future climate scenarios, although further improvements are needed for long-term accuracy.
This paper highlights the urgent need to enhance water system resilience in response to climate-induced scarcity, using a dynamic multisectoral model to analyze the macroeconomic impacts of temporary water shortages, revealing how firms' investment foresight influences their responses and the economy, with sector-specific insights indicating both negative impacts, particularly in agriculture and energy, and potential competitive benefits in certain sectors, ultimately recommending that firms prioritize anticipation and resilience-building measures across all sectors.

The article emphasizes the importance of providing training and supporting resources alongside open science initiatives to enhance accessibility and reduce barriers in the field. It suggests that these educational resources should be customized to cater to diverse user profiles, including neuroscientists, computational scientists, and educators.
It is important to have scientifically analyzed data to support the policy direction for children's schools, as they are a vulnerable group when it comes to emerging infectious diseases. [hotspot – schools]
A study of the Yangtze River revealed that labile dissolved organic matter and nitrogen inputs significantly influence the spatiotemporal variations of dissolved greenhouse gases, with observed concentrations lower than the global average but showing an increasing trend in N2O levels from 2004 to 2018, underscoring their importance in global GHG emissions and budget estimations.
The article highlights the rapid spatial succession and increasing community complexity in glacier-fed ecosystems, revealing the adaptive responses of organisms to environmental changes.

Water is essential for life and producing food, energy, minerals, and industrial goods. As planetary populations grow and a changing climate triggers floods, droughts, and other environmental extremes, access to clean water sources becomes increasingly competitive. Inadequate infrastructures, poor resource allocation, and outdated ecological restoration principles compound an already prescient problem.
