Potential utilization of water and land in Jordan [East Bank of Jordan: study of water requirements for agricultural development purposes on the national level]
1988
Hareiz, B.D.
This work study, compares and evaluates five common methods of estimating crop water requirements using available data from Jordan; establishes an agroclimatological zoning for Jordan based on soil, topography and climate; estimates the potential water requirements (WRP) for different agroclimatological zones all for the purpose of identifying an optimal land and water use priorities for agricultural development. As a result of dividing the land according to land slope, annual rainfall and soil parent material, 35 agroclimatic subunits were established to represent the East Bank of Jordan lands. Comparing1589the different methods of ETP estimation, the monthly values of ETP obtained by Hargreaves and Jensen-Haise methods are very closely related to ETP measured by class A pan at most of the subunits established. About 62.7% of the total country area is recommended for range land and 25.6% could be used for cereals, fruit trees and vegetables, where 8.5% could not be used for agriculture. The result showed that about 12855 million cubic meters (MCM) of water are required for irrigation to reach the optimal land
