Food crisis and shortage

In the past few years it’s been noticed that the quantity of food all over the world is decreasing while the need of the same has increased a lot. This has led to the imbalance in the demand and supply phenomenon of Economics. The overall impact of this on the society is the spectre of a hungry world, political upheavals and impatient and dissatisfied consumer.
Some two centuries ago, British Political scientist Thomas Rober Malthus proposed a theory. As per his theory he stated that population will grow till it outstrips food production, and then famines, wars and epidemics will intervene to restore the balance. This shows that today’s condition had been estimated by the great people many years ago.
One of the main reasons for this unbalance in the food supply, price and demand is the ever increasing amount in the population. There are so many mouths to feed in today’s time. In 1950, the world’s population was near about 2.5 billion. Some years back it crossed even 6 billion marks. According to a report submitted by United Nations Population Divisions, the world population would be somewhere between 8 and 10 billion by 2050.This is giving a warning to the entire world for the near future if not controlled at present. In relation to the increasing population if we see the food production ratio then we can see that in 1950, world food grain production was 631 million tonnes. This increased by about 3 times to 1.843 MT by 2000 and further to 2,075 MT in 2007. This proves that the grain production is more as comparatively to the increase in the population.
In future but the grain production would not be the same. Earth has its capacity of yielding. If the population goes on increasing then the food production will not be the same. Moreover now a day more and more of the land is being used in the building of the factories, schools, houses etc. Most of the land which was being used in the cultivation is now used in the commercial activities. So the land coming under filed is reducing. This is also reducing the total output of the fields.
