The UN Meteorological Organization (WMO) just released a report showing the climate crisis will cause the number of people without enough potable water will rise to 5 billion by 2050. That will be over half the world's population.

Global heating has accelerated the lack of fresh surface water, ground water, and water embedded in snow, ice, and soil, by a net of 0.4 inches (1 centimeter) annually. It is why one-quarter of all cities now experience water shortages on a regular basis.
The 2021 State of Climate Services report from the WMO reveals that over 2 billion people around the planet are in countries with water stress and 3.5 billion have inadequate access to water for at least one month every year. That represents over 44% of the global population of 7.9 billion this year.
Three decades from now the total population which will be without sufficient water will have grown to 5 billion. That works out to 52% of the estimated global population of 9.7 billion at that time, according to other UN statistics.
Think about that. By 2050 one out of every two people on the planet will not have access to enough fresh water to survive.
The report also notes that, for every 2° C (3.6° F) increase in global temperatures this century, “assuming a constant population, an additional 8% of the population now will be exposed to new or aggravated water scarcity.”
According to the WMO analysis, the regions suffering the worst from water stress in 2018 were Northern Africa (109%), Central Asia (80%), Southern Asia (78%), and Western Asia (60%).

"At a country level," the study continued, "35 countries are experiencing water stress of between 25-75% and 25 countries are considered seriously stressed, with figures above 75%."
If that were not bad enough, the UN notes that 107 of the 195 countries in the world are currently “off track to hit the goal of sustainably managing their water resources by 2030” through an effective Integrated Water Resources Management (IWRM) program.
“In 2020,” the report goes on, “3.6 billion people lacked adequate sanitation services, and 2.3 billion lacked basic hygiene services. The current rates of progress need to quadruple in order to reach the global target of universal access by 2030.”
Current infrastructure spending on water programs virtually everywhere is currently far less than that. Meanwhile, the report goes on, “the number and duration of droughts since 2000 …increased by 29%.” Most of the deaths tied to droughts occur in Africa, a region which despite its rapid economic and population growth remains grossly underreported. This is especially so in Sub-Saharan Africa, where available water sources are rapidly dwindling.
At the same time that the amount of potable water is literally drying up in much of the world, the report also notes how extreme weather events have increased flood-related water disasters by 134%. The UN notes that most of these were recorded in Asia, which are rarely given the same coverage as equivalent flood-related disasters in locations such as Germany and Belgium this summer.
Besides the obvious that there is growing inequity in how the climate crisis is affecting the world’s supply of fresh water, the World Meteorological Organization points to more ready availability of data and forecasting tools to help the world’s population survive this increasing threat to humanity’s survival. As it notes, for the members of the WMO:
With less water for all, access to clean and safe sanitary and drinking water come first to mind as pressure points. But riverine and other freshwater sources are also critical to agriculture, transport, and hydroelectrical power more than ever. All living creatures require access to water as well, and the lack of it is creating high stress to global ecosystems.
What this report makes clear is the path to water survival ideally relates to global cooperation in data analysis, forecasting, and alternative solutions to provide adequate water supplies to everyone.
Unfortunately for all, as the pattern of inadequate data-sharing shows, the more likely scenario which is already showing up throughout the planet is to fight for control of water systems on a national basis. This is present in Africa in locations such as Ethiopia, which is tightly securing water access to keep its hydroelectric power systems functioning as effectively as possible. In Asia China is dominating water management throughout the Mekong Delta region which extends down into Vietnam, Laos, and Cambodia.
There is also a growing pattern of wealthy but already arid countries such as the United Arab Emirates beginning extensive use of conventional aircraft as well as specially designed drone aircraft for cloud-seeding. While the technology is already benefiting the UAE, the presence of large-scale cloud seeding will eventually further disrupt global rainfall patterns.
As this fight for control heats up along with the temperature of the planet and resources dry out, this will result in regional wars. This time the battle will be over lakes, rivers, and streams, who gets to decide how much flows from each and who gets it.
Climate Survival Solutions is developing effective wastewater management and conversion solutions that could provide relief to some, but much more will need to be done.
