Droughts and Famines Droughts occur when there is a prolonged period when the average rainfall is below average; more likely to cause famine in places where most food is grown locally than in places where most food is imported Crops grown without irrigation may produce low yields or fail altogether; if drought occurs, there may be no seed to plant crops the following years (and can continue for many years.) People can usually survive through one season of crop failure (food saved from previous season or by importing food in); if drought lasts for several years, more serious problems can occur (ex: soil may be less able to support the production of food crops)
