Please see below recent water-related change, including the United Nations Sustainable Development Goal goal six (SDG 6) of ensuring clean water and sanitation by 2030.
- Of the world's 7.7 billion people, 2.1 billion still lack consistent access to safe drinking water at home, according to the latest World Water Development Report, published each year by the United Nations.
- Further reading:
- More than 700 million people already lack access to clean water. Quartz’s breakdown of Earth's looming shortage showed how our most critical resource is drying up, and where the scarcity could cause wars.
- For many others, water scarcity is a problem about to happen. By 2025, one in every two people on the planet will live with water stress. For one in nine, the problem is already here. The World Health Organisation estimated that 844 million people lack basic drinking water; some two billion use a source contaminated with faeces.
- Used water routinely gets flushed down the toilet or sink, but water shortages are now forcing people to ask not whether but how to treat and drink used water, and around the world there is a growing range of approaches to turning wastewater into drinking water.
- Further reading:
- Two-thirds of the world’s population could experience water shortages by 2025, according to World Wildlife Fund. As a result, ensuring that water is clean, efficiently used, safely stored, and transported is becoming a major priority across growing ecosystems.
- Finding a safely managed source of water is a daily challenge for more than two billion people worldwide, and water, sanitation and hygiene-related diseases such as cholera, dysentery and typhoid are still to blame for the deaths of one million people a year.
- Water has ranked in the top five risks for seven consecutive years in the World Economic Forum’s Global Risk Report. And, points out Raconteur, if you look at the headline threats to humanity and the planet over the next decade, as pinpointed by 1,000 experts, all but one are linked to water. These include extreme weather, natural and man-made disasters, climate change, biodiversity loss and ecosystem collapse.
- Raconteur warned too that, while other global risks have peaked and subsided, water has stubbornly remained. It is the ultimate public goods challenge, complex and inter-connected across many aspects of society. Tackling the issue requires collaborative, cross-sector solutions and a shift by all stakeholders to place a higher value on water.
- One of the largest hurdles of water resource management is the absence of comprehensive data on consumer use, noted the World Economic Forum. Smart meters are a recent trend in cities throughout the world to provide valuable information for water resource management. In London, Thames Water plans to install over 3 million water meters to provide consumer with detailed usage information encourage sustainable behaviour.
- Networked monitoring systems can also help anticipate system failures and other potential hazards. Singapore’s water grid system, WaterWiSe, monitors pressure and water quality to detect bursts and leaks and collect aggregate data to predict the impact of operational events such as pipe closures and isolation. Similarly, Melbourne and Perth have introduced a new IoT system that can optimize corrosion inspections and increase the life of infrastructure.
- Over 15,000 litres of water is used to make one pair of jeans, according to a BBC investigation.
- Water covers 71% of Earth’s surface yet only 2% of it is accessible as a source of fresh water. Pressure on this limited resource is rising, a trend likely to continue, warned Chatham House. It is important to recognise that it is not just city dwellers who consume water. Agriculture, industry and tourism often require more water than the municipal water supply. Globally, 70% of fresh water is abstracted for agriculture, but locally in heavily irrigated areas this can rise to 90 %. A healthy environment also requires fresh water; the quality is as important as its volume.
- According to a recent study, microplastics have been found in 90% of the world’s most popular bottled water brands.
- Water covers 71% of Earth’s surface yet only 2% of it is accessible as a source of fresh water. Pressure on this limited resource is rising, a trend likely to continue. By 2050, 66% of the world’s population will be living in urban areas but will they face a future in which water is rationed, asked Chatham House.
- Safe water enterprises (SWEs) are already changing the lives of millions by bringing safe drinking water within reach of some of the world’s poorest and most marginalised communities. A new EY/Unilever report aimed to illustrate their potential to change hundreds of millions more, accelerating progress toward the Global Goal of equitable access to safe, affordable drinking water for all by 2030.
- Current water infrastructure is like “a dinosaur in today’s climactic age”, warned Quartz. From rainwater catchments to direct potable reuse, its latest installment of “Shallow Waters” explored the unlikely methods engineers are trying on the hunt for sustainable solutions to water scarcity.
- Meanwhile, a recent report on water resources along national borders by Quartz found that two-thirds of the world’s frontier rivers aren’t governed by cross-border agreements, placing hundreds of millions of people at risk in the event that governments clash over those resources. There are currently open or potential water disputes between dozens of countries including the US and Mexico; India and Pakistan; Israel, the Palestinian territories, and Jordan; and between Egypt and almost all of its southern neighbours along the Nile.
- Linkages Update brought together the IISD's recent coverage of issues related to SDG 6 (clean water and sanitation). As IISD reported on the SDG 6 discussions recently, “the world is not on track” to meet the SDG 6 targets by 2030.

- A plan to tow an iceberg from Antarctica to fix Cape Town’s water crisis could reportedly supply up to 30% of the South African city’s annual needs.
An Indian government thinktank has warned that 600 million people in that country are at risk of extreme water scarcity and that 21 cities are likely to run out of groundwater in the next two years. This is not just about thirst. About 80% of India’s water is used for agriculture. Less water means lower crop yields, less food, higher food prices, and, perhaps, future political upheaval, warned GZEROMedia.
People shouldn’t treat water as private property, argued Quartz. Communities could be convinced to share access to groundwater if they’re presented with the facts.
There are two types of water, found Quartz, and they vary slightly in the electrical fields they generate.
Wars have been fought over it. People can’t live without it. And a growing global population is thirsty for more, claimed GZEROMedia. So, what happens if a major city runs out of water? Nearly 4 million people who live in Cape Town, South Africa, recently came close to finding out. Earlier this year, it looked like local authorities might have to ration water at gunpoint as the reservoirs that supply the city and its surrounding farmland started to run dry after three years of drought.
Cape Town isn’t the first big metropolis to face a water crisis in recent years. Sao Paulo, population 20 million, had a similar scare in 2015. There will be others, warned GZEROMedia, as booming urban populations meet an increase in severe weather due to climate change

- While some countries have an abundant supply of fresh water, others do not have as much. UN estimates, analysed by the World Bank suggest that many areas of the world are already experiencing stress on water availability. Due to the accelerated pace of population growth and an increase in the amount of water a single person uses, it is expected that this situation will continue to get worse.
- The ability of developing countries to make more water available for domestic, agricultural, industrial and environmental uses will depend on better management of water resources and more cross-sectorial planning and integration. There is now ample evidence that increased hydrologic variability and change in climate has and will continue to have a profound impact on the water sector through the hydrologic cycle, water availability, water demand, and water allocation at the global, regional, basin, and local levels.
- Properly managed water resources are a critical component of growth, poverty reduction and equity. The livelihoods of the poorest are critically associated with access to water services. A shortage of water in the future would be detrimental to the human population as it would affect everything from sanitation, to overall health and the production of grain.
- Freshwater use by continents is partly based on several socio-economic development factors, including population, physiography, and climatic characteristics. It is estimated that in the coming decades the most intensive growth of water withdrawal is expected to occur in Africa and South America (increasing by 1.5-1.6 times), while the smallest growth will take place in Europe and North America (1.2 times),
- A common perception is that most of the available freshwater resources are visible (on the surfaces of lakes, reservoirs and rivers). However, this visible water represents only a tiny fraction of global freshwater resources, as most of it is stored in aquifers, with the largest stocks stored in solid form in the Antarctic and in Greenland's ice cap.
- The oceans are in turmoil, but unfortunately most of it is out of sight and therefore out of mind. In Commodifying the Oceans, Environmental sociologist Stefano Longo explored the multiple threats to the oceans, from overfishing to coral reef collapse to ocean acidification.
- Ocean acidification represents a serious threat to marine biodiversity. Progressive ocean acidification will also increasingly slow the growth of corals and shell-forming reef organism.
- The average global ocean temperature is expected to rise by between one and four degrees Celsius by 2100. An increase in seawater temperature will affect the reproduction period of fish and shrimp and may result in large-scale migration of fish.
- As global population increases and people become wealthier, agricultural production will need to likewise increase, but food systems may become more stressed because of competition for water.
- Water is also used in everyday products at astounding rates - e.g. a single cup of coffee costs 130 litres of water, while about 18,900 litres are needed to produce 1 kg of roasted coffee.
- According to The Ripple Effect, The Fate of Freshwater in the Twenty-First Century (Alex Prud’homme, © 2011, Scribner, a Division of Simon & Schuster, Inc.):
- By 2025 as many as 3.4 billion people will face water scarcity.”
- For much of history, people have fought over surface water...but today, the biggest water wars are over groundwater
- Ageing infrastructure is a growing problem
- Thousands of industrial spills, many left over from a less regulated time, continue to poison groundwater, leak toxins into rivers and lakes, and impact human and environmental health
- Agricultural runoff is now the biggest single source of water pollution in some countries
- In short, we no longer have the luxury of ignoring our impact on water supplies. We must increase our knowledge the new hydrologic reality and adapt.
- Growing coffee and other commodities in places low in fresh water supplies is still common in parts of Africa. The result is the mass-transportation of water from the driest parts of the world to the wettest.
- Elixir argued that we need to treat the world’s finite water supplies with deep respect and that in the long term, for all our vaunted technologies, many of the solutions and pathways to sustainability lie in making water conservation an integral part of everyone’s lives.
- In spite of "evapotranspiration", which returns about 60% of annual precipitation back to the atmosphere, the soils in large areas of the Southern Hemisphere have been drying up in the past decade.
- Newsweek reported that Alaska was looking at selling 3 billion of gallons of water for bottling in Mumbai, shipped via tanker. This would mark one of the first major water transfers of this sort, making water a globally traded commodity.
