Seasonal human migration


Seasonal human migration is very common in agricultural cycles. It includes migrations such as moving sheep or cattle to higher elevations during summer to escape the heat and find more forage. Human labor often moves with fruit harvest or to other crops that require manual picking.

While the culture of many crops (especially "dry" crops) has become entirely mechanized, others, such as fruits and vegetables, still require manual labor, at least for harvest, and some, such as tobacco, still need manual labor for its culture. Much of the work was once provided by family members or boarding students, but thet are less available now, and farms are larger. Now, migratory workers provide much of the hand labor required in agriculture in the US and other countries. Labor contractors arrange with farmers to provide the necessary help at the seasonal time, often with foreign nationals whose employment opportunities are more limited in their home areas.

A number of migratory contractors, known as "custom harvesters", move with their combines to follow the wheat harvest in the United States and Canada. as the season moves north. Some crop dusters are also migratory, following seasonal patterns of need.

Most commercial beekeepers in the US are migratory, spending winter in warm climates and moving with the spring to follow the bloom, or pollination contracts for almonds, apples, blueberries and other fruits and vegetables that require bees. Migratory beekeeping also is practiced, especially in France, Australia, South Africa and Argentina.
