This article addresses the need to profoundly expand the way we think about freshwater. Stressing water’s role as the bloodstream of the biosphere, the article highlights water’s functions in sustaining life on the planet (control, state and moisture feedback functions), the role of water partitioning changes in inducing non-linear change at multiple scales, and humanity’s influence on a social-ecological system’s capacity to adapt and continue to function. It reviews water’s roles during its journey through the upper layers of the land mass, different types of water–ecosystem interactions, and water’s roles in landscape-scale resilience building.

This paper reviews water pricing reform in China after 1980, including framework, process, forces and considerations. China collects a water resources fee, a water supply tariff for hydraulic engineering, an urban water supply tariff, a wastewater collection and treatment tariff, and a pollutant discharge fee. The reform has been an exploration process. In theory, a comprehensive, systematic and advanced policy and framework have been developed. However, in practice, the reforms fluctuate among economic, social and environmental targets; do not comply with the reform objectives; and are heavily affected by external social and economic factors rather than by internal factors.

This article investigates the knowledge and understanding of water risks, and how these are perceived in the private and public sectors. The article is based on a case-study catchment dominated by agricultural activity near Grabouw, in the Western Cape, South Africa. Starting with an overview of the hydrological context, the article follows with a discussion of the current water challenges and water-related risk perceptions of private- and public-sector actors. A conceptual framework is proposed, mapping the different water security risks. The article suggests that water management is improved when different actors acknowledge their shared water risks.

The improvement of future responses to drought requires evaluating past management practices. This article presents a methodology to assess drought management through the analysis of six key policy dimensions. It uses a qualitative approach that combines different sources of information, including both factual data and stakeholders’ perceptions. The assessment is based on a six-case study in Europe having different spatial scales and characteristics, to capture the context-specific nature of response to drought. The results of the assessment help analyze drought management from a risk-management perspective as well as to identify key policy gaps and recommendations.

Large irrigation systems seem to be the logical add-on investment to the hydropower projects which are being planned in the Mekong Basin. Economic evaluations of irrigation schemes to date have not considered environmental costs and uncertainties about utilization. Comparisons between economic returns and poverty alleviation benefits from irrigation and from investments in other sectors are also sparse. A benefit–cost analysis of prospective irrigation investments in Lao PDR considering all these factors found that farm-scale irrigation investments performed better than large-scale investments. The benefit–cost ratio and head-count poverty reduction from large-scale irrigation investment were also substantially lower than for education, road construction and agricultural research and development.

Agriculture policy changes in Saudi Arabia are investigated by water footprint (WF) assessment. WF is calculated with the model SPARE:WATER for 3758 irrigated sites. The WF of agriculture areas (WFarea, km3 yr−1) has decreased (–17%) since the year 2000 to 13.84 km3 yr−1 (2011), which is mainly caused by the reduction of cropland by –33%. Nevertheless, water consumption per field has increased about 16%, which can be attributed to the cultivation of fodder crops (+12%). A scenario analysis revealed that a shifting cropping pattern towards less fodder crops reduces WFarea by –15%, and implementing improved irrigation technology leads to a combined reduction of up to 32%.

Water, sanitation and hygiene (WaSH) services in public spaces are examined from the political economy perspective in Nigeria. Through field observations and interviews, the study observed that WaSH practices at public spaces are less than optimal on account of poor or outright absence of necessary WaSH infrastructure and weak or non-existent regulation and enforcement of necessary standards, among other challenges. Socio-economic factors related to the category of users and the proprietary interests of specific spaces largely accounted for WaSH services inequality. It is argued that the failure of the state to guarantee functional WaSH infrastructure and enforce standard practices opens space for differentiated practices and standards consistent with specific interests.

Water is an issue that relates to all aspects of human development in Africa, including health, agriculture, education, economics, and even peace and stability. But the perception that Africa has perpetual water scarcity and is heading towards water crisis is challenged by a significant number of water professionals. Although most agree that Africa suffers from economic water scarcity, physical water scarcity could possibly be controlled with better water management. The large amount of international aid granted annually to Africa is a subject of criticism. This article examines the water crisis in Africa, whether it is a myth or reality, and reasons thereof, and suggests remedial measures.

Since the concept of virtual water was put forward, there has been an increasing number of papers on the topic, as a result of which virtual water is now being mainstreamed in the water policy world. Unfortunately, virtual water trade strategy as a solution to water shortages is wrong and fallacious. Although the virtual water trade theory is considered a descendant of the comparative advantage theory of economics, it is in fact an over-simplification, going from the truth to fallacy. To make decisions of virtual water trade based on only one production factor, water, though there are many other production factors that influence the allocation of resources at the same time, is misleading theoretically and practically.
