The Earth's population is nearing its peak, projected to be reached by 2050. Acording as per a study by Earth4all a decline in population is expected after that peak.
Earth4all analyzed two scenarios for population changes in the 21st century. The first scenario, "Too Little Too Late," assumes continued economic development, and some of the poorest countries will overcome poverty.
Under this scenario, the world population could peak at 8.6 billion by 2050 and drop to 7 billion by 2100.
The second scenario, "Giant Leap," assumes a peak of 8.5 billion people around 2040, followed by a decline to about 6 billion by the end of the century.
This can be achieved through investments in poverty reduction, education, and healthcare, as well as policy changes related to food and energy security and gender equality.
Researchers analyzed ten world regions, including Africa, China, and the United States, with the highest population growth currently occurring in African and Asian countries, notably Afghanistan.
The Earth4all study showed lower population estimates compared to UN predictions. The UN projects the world population could reach 8.5 billion by 2030, 9.7 billion by 2050, and peak at 10.4 billion by 2080, remaining at that level until 2100.
The researchers emphasize that overcoming the demographic boom could alleviate pressure on nature and the climate.
