MAINTAINING THE HYPER-ARID FORESTS OF ABU DHABI BY SUSTAINABLE IRRIGATION USING TREATED SEWAGE EFFLUENT IN CONJUNCTION WITH GROUNDWATER

The hyper-arid forests of Abu Dhabi provide valuable ecosystem services, but they require irrigation to survive. Over 80 percent of these forests are irrigated with groundwater that is now threatened. Thus, the Abu Dhabi Government passed Law Number Five in 2016 that seeks to reduce groundwater abstraction by specifying limits on irrigation takes. Ms Al Yamani measured the actual water requirements of three major forest tree species, Al Ghaf, Al Sidr and Al Samr, irrigated with either groundwater or treated sewage effluent. From her research, guidelines were proposed to support application of Law Number Five. Ms Al Yamani's recommendations will lead to groundwater savings of 35-70 percent compared to current practice, and encourage the use of treated sewage effluent as an alternative source of irrigation to sustain Abu Dhabi's forests.
