Define some of the factors influencing world food demand:

1. Population Growth: World population growth is a major contributor to food demand. As population increases, so does the need for food to nourish people. Global population growth is estimated to increase from 8.5 billion people in 2020 to 10 billion by 2050. 2. Changing Dietary Patterns: Dietary preferences, particularly in the developing world, have been shifting from staples such as grain-based diets to higher-value and nutrient-rich items like protein-rich diets, fresh fruit and vegetables. Increased demand for these types of foods drives world food demand. 3. Urbanization: Urbanization is another key factor in driving world food demand. People in urban areas are more likely to have higher incomes, giving them the ability to purchase foods they would not otherwise be able to afford. 4. Climate Change: Climate change has a significant impact on world food demand, as it affects availability and cost of food in various regions. Droughts and other extreme weather events can harm crops, leading to shortages and higher prices. 5. Food Waste: Food waste is also estimated to be a major factor in world food demand. It is estimated that almost one-third of all food produced globally is wasted. Reducing food waste would reduce the need for additional food production and could help to decrease world food demand.
