Answer:
The answer is C. Irrigation.
Explanation:
Irrigation is the process of applying water to the crops artificially to fulfil their water requirements. Nutrients may also be provided to the crops through irrigation. The various sources of water for irrigation are wells, ponds, lakes, canals, tube-wells and even dams. Irrigation offers moisture required for growth and development, germination and other related functions.
The Middle East's climate and environment make living harsh, so the Middle East requires water resources and suitable land for agriculture. Much of the land that is available for producing food is destroyed by increasing desertification.
Desertification is a sweeping environmental problem, with vast effects in countries such as Syria, Jordan, Iraq, and Iran. Universal causes for a spread of arid environment are unsustainable agriculture practices and overgrazing.
