Research on water resource conflicts needs to be better aligned with practitioner approaches to water resources development, chiefly integrated water resources management (IWRM). This paper bridges the gap between research and practice through a novel application of the social–ecological systems framework to a set of 10 conflict cases from an IWRM initiative in rural Central America. The conflicts in the empirical cases are found to be primarily the result of sociopolitical variables, particularly low levels of trust and social capital, and peacebuilding is suggested as a promising approach to address this suite of conflicts. The paper concludes with a proposed course of research designed to further both theoretical and applied knowledge of water resource conflicts.

Following the dissolution of the Soviet Union, Central Asian countries struggled to reach an agreement on the use of their shared fresh water resources. The conflict between Tajikistan and Uzbekistan regarding construction of the Rogun Hydropower Plant in the Amu Darya Basin seems deadlocked at present, despite copious efforts made by donor agencies. Therefore, this paper examines each country’s position using the numbers featured in the media.
The business of water in a changing world: organizations, connectors and support sector

As water resources are used for an array of societal purposes, a core set of institutions manages them through a water sector with connections to other societal sectors such as food, energy and health. A framework of the sector and its connectors is presented to develop definitions and order-of-magnitude estimates of expenditures for infrastructure, equipment and service delivery mechanisms. Examples are provided for the US to represent higherincome countries and for the general case of lower-income countries. Understanding water’s business aspects can identify opportunities to improve water efficiency and lower water footprints across the global range of contextual situations.
Sefficiency (sustainable efficiency) of water–energy–food entangled systems

Water–energy–food (WEF) entanglement is intensifying and technology is being presented as a crucial solution. But time and again the implemented alternative manifests results contrary to the objectives of design or management. To advance water security, transparent and complete input–output methodologies are needed. Here, a Sefficiency (sustainable efficiency) framework is used to reason through systemic analyses of options for WEF schemes by using water quantity within a comprehensive water balance, and quality and benefits in a multilevel water-use system. An energy regime (cost and normalized functions) and Sefficiency compute performance of four cases that show flaws both conceptually and practically in current policy and scientific tendencies.

This paper estimates the agricultural production water footprint (WF) of Chile, assessing green, blue and grey WFs of the main agricultural products for the main productive regions, taking into account climatic and soil differences. Chile’s agricultural production blue WF is geographically concentrated in the lower portion of the Northern Dry Pacific and Central Chile area, which present less water availability. Thus, irrigated agricultural production in Chile, a semiarid country, is characterized by high water stress. In this scenario, public policies are required to incentivize better water management in order to reduce water vulnerability while boosting development.

This study addresses the applicability and financial feasibility of residential rainwater harvesting systems in the city of Austin, Texas. A cost-benefit analysis is used to estimate the financial return for individual households with rainwater harvesting systems. In addition, a subsidy value that could be provided by the delay of a wastewater treatment plant expansion project is investigated. The findings suggest that a residential rainwater harvesting system would not be feasible without a sufficient subsidy. The estimated subsidy is also not enough to make the cost of the harvesting system effective; however, its multi-purpose benefits are not quantified.

Municipal infrastructure for water supply and delivery often does not reach populations in rural and peri-urban areas. This article examines rainwater harvesting as a means of increasing water security in such areas, through the case of Guachtuq, a peri-urban community outside San Cristóbal, Alta Verapaz, Guatemala. The project team designed a rainwater harvesting system to improve three dimensions of water security: quantity, quality and access. The design was implemented for 12 households and evaluated for its contribution to water security and for the potential of expanding project coverage to the region and beyond. The system has improved water security. Several concerns remain, however, regarding the potential of expanding the project to other households in the region and beyond, including system cost, water quality and the individualization of public responsibility for water security.
Water policy in Spain: seeking a balance between transfers, desalination and wastewater reuse

Decision-making in water resources management is a perennial source of political debate. When a basin suffers from a structural water shortage the possible solutions are either a transfer from another basin or the use of other unconventional resources such as those obtained through desalination or water reuse. Politics and territorial interests have given rise to undesired fluctuations in Spain’s water policy, in particular with regard to transferring water from one basin to another. However, conflicts have not prevented water management in Spain from being one of the most advanced in the world, even with its unfavourable geographical context.

The Kingdom of Saudi Arabia considers treated wastewater a major water source and aims to achieve 100% use of treated wastewater by 2025. This article reviews Saudi Arabia’s treated wastewater utilization status to date. It also highlights the key challenges facing the authorities, such as the substantial growth in demand for wastewater services; low coverage of the existing wastewater collection, treatment, and treated wastewater use systems; and the capital investment needed for infrastructure development. Finally, the article highlights the initiatives taken thus far to tackle these challenges and recommends further initiatives towards successful achievement of Saudi Arabia’s treated wastewater utilization objective.
