In the postwar years of the Cold War, the technology made a real boom in the agricultural sector. The new machinery, the creation of better chemicals for treating the soil and plants, as well as for their protection from pest, resulted in much increased agricultural production.
The arable land that a single family was able to work on with the new technological advancements increased significantly. That led to significantly increased production, and also a significant increase of profit for the people engaged into agriculture. The higher production led to more stable food sources, thus in numerous countries the malnutrition was wiped away or minimized.
