I need to rephrase the below

 The water shortage in the arid climate of the Arabian Gulf countries has reached unprecedented crisis levels. Due to rapid industrial development and population growth, the demand for water increased by an annual rate of 8% (Darwish and Al Najem, 2005; Hashim and Hajeeh, M.  2005). In 2002 the Arabian Gulf countries’ average rate of water consumption was estimated at 400 l/d per capita (Dawoud, 2005). As drought conditions worsen, almost all the existing underground water resources have been developed and are being exploited at an unsustainable rate (Al Barwani,2008).
