World Water Day is held on 22 March every year to raise awareness of the importance of freshwater and the challenges billions face in getting access to safe water. A growing population, the increasing demands of human use for agriculture and industry, plus the effects of climate change all put water under threat.
To demystify the water technology landscape and elevate the most scalable solutions in this space, UpLink recently ran the Zero Water Waste Challenge, from which the top 10 water-focused entrepreneurs or 'Aquapreneurs' from a pool of 192 applicants representing 40 different countries have now been announced.
The two impact each other in a feedback loop, with global water-cycle shifts and human water use amplifying the impacts of climate change, causing extreme weather events like drought and flooding, and exacerbating water scarcity. Equally, given how carbon-intensive the water industry is, wasting water is also wasting carbon.
A new chip facility being built by TSMC in Phoenix, Arizona, for instance, says it will reclaim about 65% of the water it uses, reducing its dependence on city water. The region is grappling with population growth and increasing water scarcity due to historic water shortages in the Colorado River, which feeds water supplies.
The water sector does essential work for communities. However, it is energy intensive. Water and wastewater infrastructure is a significant greenhouse gas (GHG) contributor – making up approximately 2% of global GHG emissions, on par with the shipping industry. This means water is contributing to a warming world.
Water operators have long been stewards of an essential resource and water infrastructure is a cornerstone of every prosperous economy. At the same time, today’s water systems are major sources of global greenhouse gas (GHG) emissions: global water utilities emit the same volume of GHGs as the world’s shipping industry.
In a dry climate, with rapid urbanization and relatively high per capita water consumption, Cape Town had all the makings of a water crisis. In 2018, after three years of poor rainfall, the city announced drastic action was needed to avoid running out.
The 2030 Water Resources Group (2030 WRG) was launched at the World Economic Forum Annual Meeting 2008 in Davos, Switzerland, to help close the gap between global water demand and supply by 2030. Since its inception, the Forum-initiated 2030 WRG has grown into a network of more than 1,000 partners from the private sector, government and civil ...
Water scarcity occurs when water demand outstrips available supply during a specific period – when water infrastructure is inadequate or institutions fail to balance people’s needs. In 2022, 2.2 billion people lacked safely managed drinking water , including more than 700 million people living without a basic water service, according to the ...
To meet Sustainable Development Goal 6, Clean water and sanitation for all, the current rate of progress must quadruple. Otherwise, 1.6 billion will still be without safe water in 2030. Water treatment technologies are abundant and may be faster and more practical in many places than piped, chlorinated water.
