Conflict is a major cause and, in some cases, result of humanitarian crises. Conflict frequently overlaps with underlying social inequalities, poverty and high levels of vulnerability. Conflicts are direct threats to food security as they cause massive loss of life and therefore loss of workforce (which is particularly important, as agriculture tends to rely heavily on human labour), loss of vital livestock, and loss of land. Conflicts displace millions of people each year, often forcing them to flee with nothing and making them extremely reliant on the communities that offer them shelter and humanitarian aid. This can place unsustainable pressure on hosting communities that often face high levels of food insecurity and struggle to make ends meet.
