context_page_description: Food security is a measure of the availability of food and individuals' ability to access it. Affordability is only one factor. There is evidence of food security being a concern many thousands of years ago, with central authorities in ancient China and ancient Egypt being known to release food from storage in times of famine. At the 1974 World Food Conference the term "food security" was defined with an emphasis on supply; food security is defined as the "availability at all times of adequate, nourishing, diverse, balanced and moderate world food supplies of basic foodstuffs to sustain a steady expansion of food consumption and to offset fluctuations in production and prices". Later definitions added demand and access issues to the definition. The final report of the 1996 World Food Summit states that food security "exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life."
  Household food security exists when all members, at all times, have access to enough food for an active, healthy life.
context_section_description: Current UN projections show a continued increase in population in the future (but a steady decline in the population growth rate), with the global population expected to reach 9.8 billion in 2050 and 11.2 billion by 2100. Estimates by the UN Population Division for the year 2150 range between 3.2 and 24.8 billion; mathematical modeling supports the lower estimate. Some analysts have questioned the sustainability of further world population growth, highlighting the growing pressures on the environment, global food supplies, and energy resources. Solutions for feeding the extra billions in the future are being studied and documented. One out of every seven people on the planet go to sleep hungry. Areas are subject to overpopulation, and 25,000 people die of malnutrition and hunger related diseases every day.
