World grain production peaked in the mid-
1990s. Why was the amount of grain per person
declining?
There are several reasons that could have contributed to the decline in the amount of grain per person. Some of these reasons include:
1. Population growth: As the global population continued to increase, the supply of grain may not have been able to keep up with the demand, leading to a decrease in the amount of grain available per person.
2. Limited land availability: The amount of arable land suitable for growing grains may have been limited, leading to stagnation or even a decrease in grain production despite advancements in technology and farming practices.
3. Climate change: Changes in weather patterns and increasing occurrences of extreme weather events such as droughts, floods, and heatwaves may have impacted grain production, reducing the overall amount of grain available per person.
4. Soil degradation and erosion: Poor land management practices, overuse of fertilizers and pesticides, and ongoing soil erosion may have reduced the fertility and productivity of agricultural land, leading to lower yields of grains per hectare.
5. Structural changes in agriculture: Changes in agricultural policies, land ownership patterns, and distribution systems may have also influenced grain production and availability, potentially leading to a decline in the amount of grain per person.
Overall, a combination of these factors may have contributed to the decline in the amount of grain per person despite advances in technology and agricultural practices.
