We grow a little more than 2 billion tonnes of grains and oilseeds each year, and eat about 65% of that as humans. We convert 30% to meat by feeding livestock (and 3-5% into fuel through ethanol production). To feed 9 billion human beings by 2050, a 35% increase or so, we will have to: a) grow something like 35% more food. Very importantly, we have to do so by being more productive on the cropland we have, rather than removing more natural habitat. Hard to see how we'll do this without more and better technology. or b) feed a lower proportion of our yearly grains and oilseeds production to animals, and eat it ourselves instead. This implies eating less meat. or c) avoid using too much of our food supply for fuel. It's currently not huge, but if its growth were to continue it could become so. The answer is probably all of the above. We grow a little more than 2 billion tonnes of grains and oilseeds each year, and eat about 65% of that as humans.

It is crucial to address food security on a global scale to feed the growing population by 2050. Innovations in agriculture, such as sustainable farming practices, precision agriculture, and alternative protein sources, are being developed to enhance food production. Collaboration among governments, international organizations, and businesses will also play a key role in ensuring food security for all.
The United Nations projects the world population to reach around 9.7 billion by 2050. This estimate takes into account various factors such as fertility rates, mortality rates, and migration trends. It serves as a guideline for policymakers to plan for future resource allocation and sustainability.
2050 m = 2.05 kmTo convert from m to km, divide by 1000.
2050kg is 2.05 tonnes.
Demography is the study of human population dynamics and it is used to determine the Natural Resources that will be needed to feed the people in a region.

9 billion which means we have to make 100% more food to feed the growing population
By 2050 we should reach around 9.1 billion people.
Current projections show a continued increase of population (but a steady decline in the population growth rate) with the population expected to reach between 7.5 and 10.5 billion in the year 2050.
i think world will be robotic.
India is expected to experience the largest population growth by 2050, surpassing China as the most populous country in the world. This growth is mainly due to high fertility rates and improving healthcare leading to longer life expectancy in India.
2050
If the world is still there then yes.
Projections indicate that the world's human population will reach 9.2 billion in 2050
There will be close to 60 million people in Germany in 2050, and 65 % of the population will be elderly.
In 2000, government officials in Luxembourg expected 700,000 people to live in Luxembourg in 2050.
