This editorial introduces the Special Issue titled "Water Resources and Sustainable Development," underscoring the critical need for sustainable management of water resources in light of increasing demand, climate change impacts, and pollution. The issue delves into the intricate relationship between water availability, quality, utilization, and the socioeconomic determinants shaping these aspects, highlighting the necessity for novel, balanced strategies that cater to societal, economic, and environmental requirements. The research within this Special Issue is segmented into four key areas: understanding hydrochemical properties and water quality; evaluating anthropogenic effects on water resources; strategizing water resource management; and applying technological innovations in water resource management. Collectively, these studies broaden our comprehension of water resources and sustainable development, stressing the importance of continuous research in this sphere. As we look ahead, this editorial accentuates the importance of ongoing exploration and innovation in these pivotal areas, focusing on understanding climate change implications, mitigating human-induced impacts, refining water management strategies, and harnessing technological advancements. Its overarching aim is to propel worldwide initiatives towards achieving comprehensive water security and sustainability. [ABSTRACT FROM AUTHOR]

To investigate the monitoring history and long-term change trends in surface water quality in China since the reform and opening up, the history of surface water environment monitoring is summarized, including monitoring scope, monitoring methods, and technical requirements. Temporal and spatial patterns of surface water quality in China were analyzed based on the monitoring results. In the past 40 years, the monitoring targets for surface water quality have been continuously improved, the frequency of monitoring has become more science-based, and the monitoring indicators are now comprehensive. Overall, the temporal change trend in surface water quality has followed a "fluctuating changes stage—rapid deterioration stage—fluctuations stalemate stage—rapid improvement stage" pattern. However, the current regional surface water quality is still in a polluted status, and there is a gap between surface water quality status and the goal of building a well-off society. At present, China's surface water pollution is prone to high numbers of incidents and the treatment of surface water pollution has entered a crucial stage. The potential for the continuous reduction of major pollutant discharges has become more challenging, and the marginal cost for pollution control has increased. It is very difficult to comprehensively solve the outstanding water environment problems. In addition to strengthening the existing work on surface water quality control, it is also necessary to strengthen the work of risk identification, early warning, and regulation implementation of the surface water environment. During the 14th year plan period (2021–2025), the overall planning on water resources, water ecology, and water quality will be implemented, and beautiful rivers and lakes will be created.

Water quality and availability are critical issues currently addressed by agricultural education professionals. Extension professionals need to employ innovative approaches to help residents adopt practices and technologies to reduce the impact of urban landscapes on water resources. This study explored how individuals' dissatisfaction relative to their perceived importance of either clean water for large and local water bodies or plentiful water for local water bodies related to their intent to engage in landscape best management practices following a tailored message. Individuals were randomly assigned to receive a message appealing to improving water quality through good fertilization practices or a message appealing to improving water availability through good irrigation practices. Those who assigned higher importance but perceived lower satisfaction with clean water had greater likelihood of engaging in most fertilizer best practices after receiving a tailored message compared to those who assigned lower importance and perceived higher satisfaction with clean water. Those who assigned higher importance but perceived lower satisfaction with plentiful water were more likely to engage in one of the five irrigation best practices compared to those who assigned lower importance and perceived higher satisfaction with plentiful water after receiving the message. Agricultural education programs should tailor messages to dimensions clientele perceive as important but with which they are unsatisfied, especially when intent is lower. [ABSTRACT FROM AUTHOR]
