West Asia’s internal and external renewable blue water resources vary considerably from country to country (Figure 2.1.2, Figure 2.1.3). Iraq has large internal renewable blue water resources, while for countries such as Kuwait and Bahrain the resource within their borders is very limited, and they depend almost entirely on non-conventional sources such as desalinated seawater and treated wastewater (CEDARE and AWC 2014).

Total renewable blue water resources are calculated as the total renewable blue surface water and the total renewable blue groundwater, excluding the overlap between them, taking into consideration the net external blue surface and groundwater resources by subtracting the outflows from the inflows. A more precise estimate of the total annual renewable water resource requires inclusion of both green and blue water resources (Abuzeid 2014; CEDARE et al. 2014).
