Famine can stem from natural causes such as droughts, floods, earthquakes
, insect plagues and plant disease. It can also stem from man-made causes such as wars, civil disturbances, sieges and deliberate crop destruction.
Undernutrition - The outcome of prolonged insufficient food intake and/or low absorption of food consumed. This generally applies to energy levels, but may also relate to vitamin and mineral deficiencies.
Undernourishment or Chronic Hunger -
The status of persons when food consumption regularly provides less than their minimum energy requirements. The average minimum energy requirement per person is about 1,800 kilocalories (kilocalories are commonly referred to as calories
) per day. (The exact requirement is determined by a person's age, body size, activity level and physiological conditions such as illness, infection, pregnancy and lactation).
Malnutrition - A general term for a range of circumstances that inhibit good health, caused by insufficient or unbalanced food intake or from poor absorption of food consumed. The term refers to both undernutrition (food deprivation) and overnutrition (excessive food consumption with regards to energy requirements).
Food security - Exists when all people at all times have access to sufficient, safe and nutritious food that meets their dietary needs for an active and healthy life.
Food insecurity - Exists when people lack access to sufficient amounts of safe and nutritious food, and therefore do not consume enough for an active and healthy life. The situation may result from unavailability of food, inadequate purchasing power, or inappropriate food distribution at the household level.
Integrated Food Security Phase Classification (IPC) Acute Food Insecurity Phases
Phase 1: None/Minimal
Phase 2: Stressed
Phase 3: Acute Food and Livelihood Crisis
Phase 4: Humanitarian Emergency
Phase 5: Famine/Humanitarian Catastrophe
Phase 5 - Famine/Humanitarian Catastrophe thresholds
Crude mortality rates exceed two deaths per 10,000 people per day.
Global acute malnutrition (GAM) rates exceed 30%.
Body Mass Index (BMI) is less than 18.5, where prevalence far exceeds 40%.
Extreme inadequacy to meet food consumption requirements.
Less than four liters of safe water available per person per day.
