Water scarcity is seen as essentially the most significant and potentially most impactful component of the broader climate crisis, and researchers say that enormous Asian economies like India and China can be essentially the most affected from these water shortages.
Asia is an industrialization hub that’s experiencing essentially the most rapid rates of urbanization, and this may require a copious amount of water, Arunabha Ghosh, the CEO of the Council on Energy, Environment and Water, told CNBC on the sidelines of Singapore’s annual Ecosperity Week last Tuesday.
“It isn’t just the old industries like steel making, but newer ones like manufacturing semiconductor chips and the transition to wash energy which are going to require a whole lot of water,” Ghosh said. “Asia is the expansion engine of the world, and these industries are recent drivers for its economic growth.”
Global fresh water demand is predicted to outstrip supply by 40% to 50% by 2030. Ghosh warned that water scarcity must not be viewed as a sectoral issue, but one which “transcends the whole economy.”
Asian economies “must understand that it’s a regional common good and it’s in their very own interest to mitigate the risks that come their way with a purpose to prevent the economic shocks that severe water scarcity will impose,” he said.
India, now the world’s most populous nation, can be the toughest hit from water scarcity. Despite holding 18% of the world’s population, it only has enough water resources for 4% of its people, hence making it the world’s most water-stressed country, the World Bank said.
The South Asian nation relies tremendously on its monsoon season to satisfy its water demands, but climate change has caused more floods and droughts to hit the country, and has exacerbated its water shortage.
China is in the identical rocky boat
In response to independent think tank the Lowy Institute, roughly 80% to 90% of China’s groundwater is unfit for consumption, while half of its aquifers are too polluted for use for industry and farming. Fifty-percent of its river water can also be unfit for drinking, and half of that will not be secure for agriculture as well.
Although the world’s second-largest economy has made progress in its transition toward clean energy, its power system stays largely depending on coal. And if there is no such thing as a water, there can be no coal.
“Water is a necessary input for the generation of coal power plants, and if water becomes scarcer or will not be available for power generation, that plant becomes ineffective,” Ghosh highlighted.
Other developing countries within the region are in similar situations, but their water crises could possibly be harder to resolve. Countries just like the Philippines aren’t as privileged and resilient, so there is a “huge imbalance within the water crisis that we’re facing,” Shanshan Wang, a Singapore water business leader at sustainability consultancy Arup, said.

India and China are near seas and rivers, and are more threatened by rising sea levels, but they will afford technology and innovation for higher water storage systems, Wang told CNBC on the sidelines of the Singapore International Water Week last Tuesday.
Meanwhile, Wayne Middleton, the Australasian water business leader for Arup said that “we want to stay our hand up and say that we’ve not recognized the worth of our river systems and we’ve exploited them for industry uses and agriculture.” “We’ve got only recently seen the damage that we’ve done,” he said.
Countries within the West won’t likely remain unscathed by the risks related to this water crisis. Europe’s water problem is predicted to worsen as resources grow increasingly scarce as a result of the deepening climate emergency. The region saw temperatures undergo the roof in spring, after experiencing a winter heatwave that took a toll on its rivers and ski slopes.
Sectors most affected
Taiwan, home to Asia’s largest semiconductor industry, has once more succumbed to water shortages lower than two years after battling the worst drought it had seen in a century. Huge amounts of water are needed to power the plants and manufacture the semiconductor chips that go into our digital devices, and provide will be hindered if shortages occur.
“Taiwan is an enormous user of hydropower and it all the time faces a dilemma on whether to store water for its semiconductor industry to utilize, or if the water ought to be released in order that they can have more hydroelectricity power,” Wang highlighted.
“Droughts and floods are each an issue for Taiwan, so the industry is unlucky and vulnerable,” she added.
Nevertheless, Wang noted that although many manufacturing industries do need water to operate, water will not be actually getting used up and could possibly be recycled.
“Water scarcity will not be particularly problematic to those industries because a whole lot of the water will be recycled. The method pollutes the water, and lots of industries might just wish to dump the water directly back into the ecosystem as an alternative of purifying and reusing it,” she said.
“Now that there’s a crisis, there are opportunities for businesses to take into consideration find out how to close the loop … They can not just take whatever is out there in abundance for themselves.”
Water can also be playing an enormous role within the planned energy transition, and the dearth of water could impede countries’ transition to net-zero. In 2022, China experienced its worst heatwave and drought in six a long time. Blistering temperatures dried up areas of the Yangtze River, impeding its hydroelectricity capabilities — the country’s second biggest power source.

To alleviate energy risks, the country approved the best number of recent coal-fired plants since 2015 last 12 months. Beijing authorized 106 gigawatts of recent coal power capability in 2022, 4 times higher than a 12 months earlier and the equivalent of 100 large-fired power plants.
“We’d like an enormous energy transition to renewables to power our recent water supplies, and we want our water supplies to be available for energy security,” Middleton said. “We’d like to start out bringing those two conversations together quite a bit more.”
Economies which are heavily depending on agriculture could also see output drop significantly and food security could be at further risk.
In response to Australia’s Department of Agriculture, Fisheries and Forestry, the worth of agricultural production is predicted to fall by 14% to succeed in $79 billion in 2023 to 2024. That is as a result of drier conditions which are expected to scale back crop yields from record levels in 2022 to 2023.
“We will definitely construct recent water supplies and supply water to industries, customers and cities in Australia, but we’re probably not in a position to sustain enough water in longer periods of drought,” Arup’s Middleton identified.
“In fact we we’ve to make water available for our cities and our big economies and our communities, however it leaves behind a growing risk for food production and the agricultural sector,” he said.
