The world’s population has increased very fast in the last few years. Thousands of years ago, the population of humans on earth took a long time to reach one billion, but after that the number reached eight billion in just 200 years. The special thing is that since 1960, i.e. in only 65 years, the world’s population has increased from 3 billion to 8 billion.

However, despite such a sharp population growth, there are some countries where the population is decreasing. One of these countries is Tuvalu, who is struggling with its existence crisis today.

Crisis on the declining population and existence of Tuvalu
Tuvalu is a small island country located in the West-Central Pacific Ocean, now facing a population crisis. The total population of this country was once about 10 thousand, but now a period of decline has started. According to the latest data, the population of Tuvalu has decreased by 1.80 percent and currently this number has reduced to slightly more than 9 thousand. If this situation continues, then Tuvalu can reach the verge of completely extinction. This country is located between Australia and Hawaii.

United Nations prediction- population will continue to grow
In 2011, the total population of the world was 7 billion. Within just 14 years this number increased by one billion. The United Nations estimates that this number will increase continuously in the coming years. According to the United Nations report, by 2030 the world’s population will reach 8.6 billion. Then by 2050 this figure can be 9.8 billion. The world’s population is expected to reach 11.2 billion by the year 2100.

Ukraine, Japan, Greece: Countries with a decreasing population
There are some countries in the world, whose population is clearly seen.
Ukraine recorded a drastic decline of 8.10 percent in only one year between 2002 and 2023. The main reason behind this decline is the ongoing war in the country, in which thousands of people lost their lives and a large number of citizens migrated to other countries.

The population of Japan has also decreased by 0.50 percent. However, the situation here is somewhat different. While migration and war cause war in other countries, only less birthday in Japan is the reason for the decrease in population. Many incentive schemes have been started by the government, but despite this people are not showing interest in giving birth to children.

European country Greece has also recorded a decline in population. There was a decrease of 1.60 percent in a single day. Similarly, the population of San Marino has recorded a decline of 1.10 percent, Kosovo population 1 percent, and Belarus population declined by 0.60 percent. Along with Belarus, the same decline has been seen in Bosnia and Albania.

The most affected by war and migration: Ukraine
Ukraine has become such a country in the world at this time, where the population is decreasing at the fastest. Thousands of people have been killed due to the war there, while a large number of citizens have gone to other countries to take shelter. This is the reason that in a year itself, the population here has fallen by more than 8 percent.

Only less birthday in Japan
Japan is different from other countries. There is neither war nor a major problem of migration here. Despite this, the population here is declining every year. The reason is – the lifestyle and thinking of the people there. The youth is not excited about getting married and having children. Even after giving all the facilities and encouragement by the government, there has been no significant change in the situation.

Europe’s decreasing, Asia’s increasing population
If we talk about continents, then Europe is the only continent where the population is continuously decreasing. On the other hand, the population of Asia is increasing rapidly.
Asia has become the most populous continent in the world due to big countries like India, China, Pakistan and Indonesia.

Which countries are afraid of population crisis in future?
According to the United Nations, the current population of Greece is about 10 million (one crore), but by the year 2100 it can be reduced to 9 million (90 lakh). Similarly, countries like Russia, Italy and South Korea are also under threat of declining population. If these countries do not take concrete steps for population stability, then economic and social challenges may be faced in future.

Kabul water crisis: Kabul, the capital of Afghanistan, can become the first such modern capital in the world, where the water can be completely eliminated by 2030. This warning is given in a report by Mercy Corps. The report said that due to climate change, excess exploitation, random urbanization and government negligence, this crisis has become deeper.

Excessive water harness
The more groundwater extracts every year, it is 44 million cubic meters more than its natural reproduction. This is the reason that about half of the city’s borewells have already dried up. Experts say that if this situation does not change, ground water can be completely eliminated by 2030.

Population growth became a big reason
Three decades ago, Kabul’s population was less than 20 lakhs. But after 2001, it has increased a huge increase. As the population increased, the demand for water also increased, while the city is almost completely dependent on ground water. But this ground water is ending rapidly.

Not just water crisis, health crisis also
More than 80% of Kabul’s groundwater supply is polluted. People are constantly getting diseases like diarrhea, vomiting by drinking this water. A government employee from Timani district said that his family often becomes ill after drinking water in the restaurant or brushing at home.

Essential things have to be left for water
Many families have to leave food and drink to buy pure water or to dig up expensive borewells. And those who cannot afford this expense, either bring water from mosques or depend on tankers.

Status for women even more serious
Due to the Taliban rule, women are not allowed to go out alone. In such a situation, it has become even more difficult for women to bring water. A 42 -year -old woman said that ‘We do not have drinking water at all. It is affecting our life badly.

Hindu Kush’s glaciers are not getting water
Earlier the water supply of Kabul was caused by snowfall and snowfall coming from the Hindu Kush mountain, which was filled with groundwater. Now snow falls less there, and its place comes in uncontrollable floods, which do not help in recharging groundwater.

Political instability and help
American aid in Afghanistan stopped after the Taliban returned to power in 2021, including USAID help. Due to this, many important projects related to water and hygiene have stopped. This has made the situation even more serious.

Unicef Warning
Unicef has already warned that if water exploitation and mismanagement continue like this, Kabul will become a groundwater -free city by 2030. This can create not only water crisis, but also health, human and social crisis.

There is a big change in the country regarding the population of India. The report of the World Population Policy has revealed that the fertility rate in India is decreasing.

Let us know which state is at the forefront of the rise of India’s population.

Which state’s population is the highest

This is followed by Bihar, where the figure is 30.7 lakh and Maharashtra was 19.2 lakhs. In Madhya Pradesh and Rajasthan, berth registration was high.

Uttar Pradesh has increased by 40 percent since 2013, while Bihar has seen more than 16 lakh increase in 2013. Which has almost doubled in 10 years. Rajasthan and Madhya Pradesh have seen a gradual increase. In 2013, 10.4 lakh births were recorded in Karnataka, which increased to 11 lakhs by 2017, but then in 2022, to 10.4 lakhs. Tamil Nadu also had a decline trend. In Tamil Nadu in 2013, where birth registration was 11.9 lakhs, which was reduced to 9.4 lakhs in 2022.

Who ahead in sex ratio

Similarly, this sex ratio in Maharashtra is 906, Telangana 907, Gujarat 908, 916 in Haryana. At the same time, Nagaland has 1068 sex ratio which is the highest in India.

This figure reflects an increase of 2.5 percentage points in the last two years, while since 2010 this figure was on a steady decline except a brief surge in 2020.

Not only this, it was also mentioned in the report that 68.4 percent of the respondents said that it is necessary to have children after marriage. This figure shows an increase of 3.1 percentage points in the last two years. This change has happened at a time when South Korea is facing a crisis of population reduction and the government has planned many measures to deal with this crisis.

According to the statistics of Korea, a total of 238,300 children were born in 2024, which is 3.6 percent higher than a record low of 230,000 in 2023. However, South Korea’s fertility rate is still the lowest in the world and is about half of the average of the Economic Cooperation and Development Organization (OECD) member countries. Since 2018, this country is the only member of OECD whose rate is less than 1. However, by 2030, the government aims to increase it to 1, which is very important to maintain a stable population without migration.
