Key trends on population that need verification
Most developed countries have slowing population growth that is dropping below replacement rate in some countries
Legal immigration may help countries that want to maintain their population size
Many less developed countries have high population growth rates ( though those rates are slowing somewhat ) that contribute to increasing poverty, human rights abuses, health issues in those countries
Some countries have policies to manage population growth and some clearly don't
Updated Population Growth Trends - March 2023 - UN
https://www.earth4all.life/news/global-population-could-peak-below-9-billion-in-2050s
March 27—In November 2022, the world crossed a milestone of 8 billion people but new analysis suggests the global population could peak just below 9 billion people in 2050 then start falling.
The new projection is significantly lower than several prominent population estimates, including those of the United Nations. The researchers go further to say that if the world takes a “Giant Leap” in investment in economic development, education and health then global population could peak at 8.5 billion people by the middle of the century.
In the first scenario – Too Little Too Late – the world continues to develop economically in a similar way to the last 50 years. Many of the very poorest countries break free from extreme poverty. In this scenario the researchers estimate global population could peak at 8.6 in 2050 before declining to 7 billion in 2100.
In the second scenario, called the Giant Leap, researchers estimate that population peaks at 8,5 billion people by around 2040 and declines to around 6 billion people by the end of the century. This is achieved through unprecedented investment in poverty alleviation – particularly investment in education and health - along with extraordinary policy turnarounds on food and energy security, inequality and gender equity. In this scenario extreme poverty is eliminated in a generation (by 2060) with a marked impact on global population trends.

The future of humanity's "lifeblood" -- water -- is under threat worldwide, the UN secretary-general warned Wednesday at the opening of the global body's first major meeting on water resources in nearly half a century.
"We've broken the water cycle, destroyed ecosystems and contaminated groundwater," Antonio Guterres said at the three-day summit in New York, which gathers some 6,500 participants including a dozen heads of state and government.
"We are draining humanity's lifeblood through vampiric overconsumption and unsustainable use, and evaporating it through global heating," Guterres told the conference.
A report by UN-Water and UNESCO released Tuesday warned of too little or too much water in some places, and contaminated water in others -- conditions it said highlight the imminent risk of a global water crisis.
"If nothing is done... it will keep on being between 40 percent and 50 percent of the population of the world that does not have access to sanitation and roughly 20-25 percent of the world will not have access to safe water supply," report lead author Richard Connor told AFP.
With the global population increasing every day, "in absolute numbers, there'll be more and more people that don't have access to these services," he said.

UN-water-report-2023-unesco.org-Partnerships and cooperation for water.pdf file
The 2023 United Nations World Water Development Report on Partnerships and Cooperation assesses the nature and role of partnerships and cooperation among stakeholders in water resources management and development and their role in accelerating progress towards water goals and targets.
Progress towards SDG 6
Partnerships and cooperation are essential to accelerating progress towards SDG 6 and realizing the human rights to water and sanitation. Safeguarding water, food and energy security through sustainable water management, providing water supply and sanitation services to all, supporting human health and livelihoods, mitigating the impacts of climate change and extreme events, and sustaining and restoring ecosystems and the valuable services they provide, are all pieces of a great and complex puzzle. Only through partnerships and cooperation can the pieces come together. And everyone has a role to play.
Nearly every water-related intervention involves some kind of cooperation. Occurring across local to global scales, through formal and informal arrangements, water partnerships bring together different stakeholders with varying intentions.
Cooperation is critical to achieving all water-related goals and targets. Any acceleration of progress towards the sixth Sustainable Development Goal (SDG 6) depends heavily on the efficient and productive performance of partnerships.
Inclusive stakeholder participation promotes buy-in and ownership. Taking account of the different perspectives of those involved helps determine a clear, shared vision of the objectives, outcomes, and results, based on a common understanding of the problem(s).

Understanding the state, use and management of the world’s freshwater resources and designing better water policies
UNESCO established the World Water Assessment Programme (WWAP) in 2000 in response to a call from the UN Commission on Sustainable Development (CSD) to produce a UN system-wide periodic global overview of the status, use and management of freshwater resources.
Its overall objective is “to meet the growing requirements of UN Member States and the international community for a wider range of policy-relevant, timely and reliable information in various fields of water resources developments and management, in particular through the production of the United Nations World Water Development Report (UN WWDR)”. Consequently, WWAP, through the World Water Development Reprts and complementary activities, aims to equip water managers and policy- and decision-makers with knowledge, tools and skills necessary to formulate and implement sustainable water policies

Groundwater accounts for 99% of liquid freshwater on Earth and is the source of one quarter of all the water used by humans. Large volumes of fresh groundwater are present below ground surface and distributed over the entire globe; however, this volume of freshwater is irregularly distributed over the continents.
An easy and open access resource to numerous people, leading to common pool characteristics, groundwater offers tremendous opportunities to society for gaining social, economic and environmental benefits and its contribution to satisfying our demand for water is considerable.
Groundwater already provides half of the volume of water withdrawn for domestic use by the global population, including the drinking water for the vast majority of the rural population who do not get their water delivered to them via public or private supply systems and around 25% of all water withdrawn for irrigation.

Collapse of Ocean Currents. link
A study published Monday concluded that melting ice in Greenland caused by climate change could cause the Atlantic Meridional Overturning Circulation (AMOC) to collapse as soon as 2025, ushering in dramatic consequences for the planet.
The AMOC brings warm water north and east from the Caribbean, while delivering colder Arctic water south. If it were to suddenly shut down, scientists believe North America would experience weather changes such as more severe hurricanes and northern Europe would get a lot colder.
In recent years, studies have shown that the current is at its weakest in 1,000 years. Although scientists are not certain why, several studies have attributed that weakening to an influx of fresh water from the melting of Arctic sea ice, including the Greenland ice sheet, and increasing precipitation — both of which are results of global warming.
The AMOC is driven by heavier cold water sinking, which raises warm water to the surface, but since fresh water is lighter than salt water, it has reduced the tendency of colder water near the surface to sink.
an AMOC collapse would have wide-ranging effects including increased sea level rise in the Atlantic, a drop in precipitation over Europe and North America,
at the end of the last ice age, when studies suggest a “flood of freshwater spilled into the Atlantic, halting the AMOC and plunging much of the Northern Hemisphere — especially Europe — into deep cold” that lasted 1,000 years.
