The most common types of famine include food insecurity, drought, floods, civil war, economic collapse, and natural disasters. Food insecurity is when people do not have access to enough food to meet their needs. Drought is a lack of rainfall that can lead to crop failure. Floods can destroy crops and infrastructure. Civil wars can disrupt trade routes and block supplies from reaching areas in need. Economic collapse can occur when markets fail or currencies become worthless. Natural disasters such as hurricanes, earthquakes, and tsunamis can also cause widespread destruction and disrupt food production.
