Secure water supply in water-scarce regions

This research paper chapter discusses sustainable alternatives to traditional water resource management to enhance water security in water-scarce regions. It highlights technologies such as water harvesting, fog harvesting, desalination, and water reuse, while noting the associated energy demands and ecological footprints.

• Water security is defined as having access to water in sufficient quantity and adequate quality to satisfy both ecological and societal requirements.
• To improve water security in water-scarce regions, the text identifies several sustainable supply alternatives to traditional surface and groundwater exploitation, including water harvesting to maximize rainfall and ephemeral river use, fog harvesting for semi-arid regions, desalination, and water reuse.
• The adoption of innovative water supply technologies presents specific challenges, notably regarding their energy implications and the ecological footprints they create.
