Advantages

Intensive agriculture made it possible to greatly increase productivity during the twentieth century, and helped ensure a proper and stable food supply for the growing population while at the same time decreasing the amount of land needed. Agricultural productivity gains allowed for the reduction in the farming population, mostly in developed countries. Intensification of agriculture from the forties to the sixties is also known as the green revolution. Developing nations often could not profit from the advantages of modern agriculture particularly because of poor climate and lack of funds.
The increased agricultural productivity has lead to a sharp decrease of food prices.
