Economic growth and development
Answer:
Agricultural economies are still used in some countries of the Middle East, especially where other natural resources are few. These economies are often associated with a lower standard of living. Herding and livestock raising is a common means of income in areas too dry for farming. Animals raised include cattle, goats, and sheep. Farming often occurs along the coasts, but may also occur in drier areas if irrigation watering methods are used.
