This article presents the hydroclimatic changes in the Tibetan Plateau, emphasizing the delicate balance between precipitation and evaporative demand in streamflow dynamics.

The article demonstrates that while healthier diets often align with reduced environmental impacts in several domains, significant trade-offs exist, particularly regarding water use and cost. Diet quality indexes that emphasize plant-based foods offer the most consistent sustainability benefits. However, no diet pattern is without drawbacks, underscoring the importance of nuanced, multidimensional assessments and the integration of nutrition and sustainability data to inform effective policy and clear public guidance.

This chapter aligns with UN SDG Goals 6, 9 and 12 by highlighting the innovative use of cocoa waste in water treatment and bioremediation, thereby promoting sustainable practices that improve water quality and resource management.

Pesticides are extensively used to improve food production, resulting in ubiquitous pesticide contamination in surface waters due to agricultural runoff.

The electroreduction of nitrate has emerged as a promising global strategy for water purification in the face of harmful nitrate in wastewater.

Thermo-responsive polymer is becoming a potential water purification and water harvesting material.

The article provides an overview of metal-organic framework (MOF)-based composite adsorbents for atmospheric water harvesting, discussing the hydrolytic stability of MOFs, recent advances in sorption-based water harvesting devices, and the challenges and prospects of MOF-based composite adsorbents. Key points include compositing MOFs with other functional materials to address limitations in water adsorption capacity and energy-intensive regeneration, and the factors affecting the hydrolytic stability of MOFs.

This article presents a heat-pump-coupled sorbent system to simultaneously harvest water from air and regulate indoor environments, addressing global challenges related to water scarcity and energy-efficient air conditioning.

This chapter aligns with UN SDG Goals 6, 9 and 12 by promoting clean water, reducing pollution, and supporting sustainable water management practices.

This chapter aligns with UN SDG Goals 6 and 14 by addressing how anthropogenic impacts to water quality affect marine fish populations and discussing future perspectives for managing water quality and aquatic habitats.
