Within the next 40 years, food shortage may start to bear serious implications for people and governments.

Dr. Fred Davies, senior science advisor for the agency's bureau of food security said that the world population will increase 30 percent to 9 billion people by mid-century, which would call for a 70 percent increase in food to meet demand, but resource limitations will constrain global food systems.
Davies highlighted the "monumental challenge of feeding the world" and added that more efficient technologies and crops will need to be developed to address this challenge.
