This chapter analyzes the water pricing structure, reform process, and case studies in China and presents a overall picture of pricing water resources and its services during the past 60 years, particularly after 1980. China now implements a comprehensive water pricing framework and develops it step by step. The water resources fee was introduced in the 1980s, and the wastewater treatment and collection fee was developed in the late 1990s. By the 2000s, a comprehensive system was developed. Two case studies, involving Beijing and Shanxi Province, are discussed, which demonstrate increasing tariff standards in both regions. In the future, China will continue struggling with its water sector’s increasing tariff levels in order to meet its multi-objective water pricing.

This paper analyses key contributors to sustainable livelihoods in the Lower Mekong Basin (LMB), Cambodia, by focusing upon villagers’ access to assets, adaptation to shock and stress, and their degree of resilience to declines in natural resources. The study reveals that their access to the five assets for sustainable livelihoods is limited; that their capacity to adapt to shock and stress is low due to floods, drought and high food prices; and that their resilience to declines in natural resources is weak. Improvement in their capacity to adapt and in their resilience will be influenced by the degree to which they can access human, physical and social assets.

Climate change and land use change have significantly altered the water cycle, thus affecting watershed water security. Quantitative assessment of water security using the water footprint concept can improve water resource management at the watershed scale. Therefore, this study aims to investigate the impacts of climate change and land use change on water security based on the water footprint concept, with the goal of enhancing water resource management at the watershed level. In this study, we employed the Soil and Water Assessment Tool (SWAT) to quantify the spatial and temporal distribution of blue and green water resources in the Weihe River Basin (WRB), China. Multiple water security evaluation indicators, including scarcity and vulnerability, were integrated to quantify water security. Significantly, statistical analysis methods were employed to identify key factors influencing the changes in blue and green water. The results indicate that the interannual and monthly coefficient of variation for blue water is higher than that for green water, with the order being blue water > green water storage > green water flow. Hotspots of the blue water crisis are concentrated from February to July, with agricultural water use exhibiting the highest crisis (BWvulnerability = 0.814), while hotspots of the green water crisis are concentrated from April to October. Blue water is primarily influenced by climate change, particularly precipitation, while the changes in green water flow and green water storage are influenced by the interactive effects of climate change and land use change. Specifically, in the upstream, blue water is mainly influenced by precipitation (r = 0.703), while green water is influenced by precipitation, temperature, and pasture. In the midstream, blue water is mainly influenced by precipitation, temperature, and agriculture, while green water is additionally influenced by forest and pasture. In the downstream, the key influencing factors for blue and green water are similar to those in the midstream, with the difference that blue water is negatively correlated with the population (r = -0.421). Developing water-saving agriculture can effectively improve water security in the midstream and downstream. This study has identified key factors for optimizing the allocation of water resources upstream, midstream, and downstream, providing valuable insights for future research on water security at the basin scale.
