Disasters can reduce food and water security in impacted areas, either by damaging food production or water access infrastructure directly or by limiting the capacity of people to buy food and water.
Disasters can impact food and water security in different ways. Sometimes, they directly damage food production areas, for example when a drought or storm destroys crops and livestock or breaks supply chains by which people buy and sell food. Similarly, disasters can damage infrastructure that normally ensures water supply, disrupting water from reaching people who need it, or polluting existing water sources and rendering them unsafe. Other times, disasters can indirectly reduce food and water security by creating scarcity or by leaving households financially unable to purchase needed resources such as food and water.
