Hawr Al Azim is also another important issue being internationally observed! Because of the remaining of Mesopotamia marshland. However plans like Karkheh Dam and water export to Kuwait can affect this. Also Iraq did not helped the plan of restoration during Saddam Hussein because of draining up the marshland for security! This area is also a mine polluted and also oil –and gas rich which makes it even more important!
Based on secondary data analysis, average sub-cathment level Wheat yield ranges from 0.3-1.5 tons/ha (rainfed) to 2- 4.4 tons/ha (irrigated) across Karkheh in 2003. Maize yield shows even higher variability and is between 5-11.5 tons/ha for the same period. This variation is largely related to water availability and fertilizer use.
1. For both rainfed and irrigated areas, better and increased use of inputs. 2. For irrigated areas, better targeted irrigation applications. 3. For rainfed areas, exploring means of additional water application wherever possible, though considering possible trade-offs with downstream areas. 4. While opportunities of improving productivity exist in both the upper and lower Karkheh, the upper basin appears to be most promising for productivity improvement potential.
