Question

4A- Write a page constructive critique of “Sustainable Water Management Assessment and Recommendations for the Emirate of Abu Dhabi". You should consider what its strengths are and how it could be improved. Imagine that you were handed this analysis as a "draft report" and it was your job to improve it - what would you suggest? The suggestions you make should probably reference some of the many topics already covered by the readings. Your critique could address the methods, assumptions, presentation style, or other aspects.

Did the analysis use the right methods for their goal? Did they properly treat time preference, uncertainty, and human decision-making? Are the questions that they answered useful for decision makers?

Explanation / Answer

over the last decades water demand in Emirate of Abu dhabi has increased rapidly.the main driving forces are --- surface water is almost absent due to the scarcity of rainfall coupled with arid conditions,over-pumping practices have resulted in a severe decline in groundwater levels and quality,population growth,economic development,changes in lifrstyle ---- which have increased the demand for water. for irrigation,human consumption or industrial process,agriculture & residential uses are also need water.A large portion of this demand is provided by desalinated water, which is expensive to produce.

to solve the water problem of Abu dhabi initiatives that contribute to - a. Minimise the impact of water production, transmission and distribution on climate, air soil and marine water quality b. Ensure efficient indoor and outdoor consumption of all types of water by all sectors: buildings, industries, agriculture, amenities and forestry ..

..& also 1. Integrate the management of the three water resources

2. Adopt innovative clean solutions for water production in light of energy plans

3. Minimise water losses from desalinated water networks

4. Minimise discharges from recycled water practices

5. Limit the impact of desalination and recycled water practices on marine and terrestrial ecosystems

6. Ensure proper demand side management

7. Explore innovative solutions for groundwater conservation and use

8. Ensure high indoor and outdoor water efficiency in built environment

9. Encourage the establishment of water-efficient industries

10. Optimise water use, including groundwater, desalinated water and recycled water, for agriculture while ensuring food security

11. Minimise groundwater salinization and pollution attributed to agriculture

12. Develop low water requirements amenities sector

13. Develop low water requirements forestry sector

beside thease --- 1) increasing the capacity of artificial recharge using excess produced desalinated water & treated wastewater.

2) domestic rainwater harvesting system can be utilized to save existing surface & ground water. In many countries rain water is used as primary & potable water sourcefor domestic & irrigation purpose.

3) at some places of UAE salinity of ground water level has doubled.Here sea water intrusion is also a main cause of water salinity in the aquifer,specially near the coast which is known as brackish groundwater. Sporobolus Spicatus is normally found in coastal sabkhas (Arabic wordused for salty flat area normally occurring between desert & ocean.) with soil salinities above sea water.therefore direct sea water can be used for irrigation using halophytes (salt loving plant) in salty water agriculture will save valuable fresh water for domestic use.
