Water scarcity is among the top five global risks<\/a> affecting people\u2019s wellbeing. In water-scarce areas, the situation is grim. Conventional sources like snowfall, rainfall, river runoff and easily accessible groundwater are being affected by climate change, and supplies are shrinking as demand grows.<\/p>\n\n\n\n

In these countries, water is a critical challenge to sustainable development<\/a> and a potential cause of social unrest and conflict. Water scarcity also impacts traditional seasonal human migration routes<\/a> and, together with other water insecurity factors, could reshape migration patterns.<\/p>\n\n\n\n

Water-scarce countries need a fundamental change in planning and management. We are looking at how to do this, through the creative exploitation of unconventional water resources<\/a>.<\/p>\n\n\n\n

From Earth\u2019s seabed to its upper atmosphere, we have a variety of water resources that can be tapped. But making the most of these requires a diverse range of technological interventions and innovations.<\/p>\n\n\n\n

Catching fog<\/strong><\/p>\n\n\n\n

Water embedded in fog<\/a> is increasingly seen as a source of drinking water in dry areas where fog is intense and happens regularly. Fog can be collected using a vertical mesh that intercepts the droplet stream. This water then runs down into a water collection, storage and distribution system.<\/p>\n\n\n\n

Different types of screen materials can be used in fog collectors, like aluminium, plastic, plexiglass and alloy. The success of a system like this depends on the geography and topography, which need to be conducive to optimal fog interception<\/a>. But this could work in dry mountainous and coastal regions.<\/p>\n\n\n\n

With active engagement of local communities and technical support from local institutions, fog water harvesting is a low-maintenance option and a green technology<\/a> to supply drinking water. Fog water collection projects have been implemented in different parts of world, including Chile, Eritrea, Israel and Oman.<\/p>\n\n\n\n

Cloud seeding<\/strong><\/p>\n\n\n\n

Under the right conditions,\u00a0rain enhancement through cloud seeding<\/a>\u00a0has the potential to increase the volume of water harvesting from air. This technology involves dispersing small particles into clouds or in their vicinity. These particles act as a starting point for raindrops or ice crystals, promoting their formation. In turn, this makes it more likely to rain or snow. Read more…<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
