世上几乎一半的人使农民，他们大多数都是以传统的方式农耕，几个世纪以来，都是用牲畜和他们的肌体作为劳动力，使用着简单的统一工具。传统的农民主要生产自用的粮食和织布用的纤维，他们很少花钱购置机器、化肥和其他的现代材料。然而，在许多国家，传统的农耕方式已逐渐消失。数百万的农民搬迁到拥挤的城市，去寻找更轻松的生活，这些人必然要靠现代农业而生存。另外的几百万小户农民，便留在了原来的农场，他们也适应了现代的生产方式——化肥、高产粮种、高效的小农机等。这些小型的现代农民，在农场外面也都有工作，所以，他们也称之为兼职农民。
现代农业正在发展变化着。未来的农场，大型拖拉机将逐步减少，因为科学家们正在寻找，能够使用更少劳动力、更节省能源的农耕方式。为世界人口解决吃饭问题的农业，正日趋成功！
