Real prices will remain constant and food imports by developing countries will increase. Other analysts predict increasing constraints on world agricultural production. At the same time, they see increased incomes and urbanization leading to changing dietary patterns. Increased consumption of meat and milk in China, for example, necessitates considerably more feed grain. Even if overall supply is adequate for the world's population, it does not presently meet demand.
Uneven distribution ensures that hunger and food insecurity persist.
Demand for food is influenced by a number of factors. During the next several decades, population growth will be a significant factor determining overall and regional demand for food. Despite projections of slowed population growth rates, the UN estimates world population will be over 8.5 billion by 2025. At current rates, global demand for food will almost double in 30 years. If current trends in population growth, urbanization and income continue, global demand for food will almost double in 30 years.
