Abstract

Desalination is increasingly popular for ensuring potable water. Using the City Blueprint Approach methodology in Antofagasta, Chile, we identify the barriers, opportunities and transferable lessons that can enhance governance capacity towards the successful implementation of desalination. Antofagasta’s desalinization programme is associated with negative water-quality perceptions, environmental impacts and high energy demands. Additionally, the supply has a moderate impeding influence on water-use efficiency efforts. Consequently, we draft a priority ladder for water provision in water-scarce regions to: ensure access; reduce consumption; apply reuse; and explore renewable water resources – and if a combination of previous steps is insufficient, desalination may be applied to meet water supply shortages.

Water governance in the Mekong River Basin is complex and faces many challenges, including conflicting interests among stakeholders, inadequate legal frameworks, and limited institutional capacity

There are several research gaps in the field of water governance in the Mekong River Basin, including the role of civil society in water governance, the impact of climate change on water resources, and the effectiveness of existing water governance mechanisms

Future research in this field should focus on addressing these research gaps and developing a more comprehensive understanding of water governance in the Mekong River Basin
