2 TRANSBOUNDARY RIVE S BASINS Major River Basins of the World Source: UNEP 2001 the 263 trans-boundary rivers or lakes and many hundreds of aquifers, the basins of which contain more than half the territory and population of the world

3 The Arab region has the highest reliance on external water resources; more than 65% of the annually renewable resources originate outside the boundaries of the Arab region the major rivers in the region are the Nile River, the Euphrates and Tigris Rivers and the Senegal River. All these challenges in the region lead to a complicated hydro-political problem facing many Arab countries.

6 Water resources in the riparian countries of Egypt, Iraq, and Syria are mainly derived from very large catchments in the more humid regions to the south and north of the Arab region that are characterized by higher and more consistent precipitation. For example, Turkey the main headwater of the Euphrates and Tigris Rivers has much higher precipitation and less variability than neighboring Arab countries FACTS: 2700 kilometers long Begins in Turkey Empties into the Arab Gulf 94% of water originates in Turkish highlands The Murat Korasuyu and several other Turkish rivers join the Euphrates in central Turkey The Khabur joins the Euphrates in eastern Syria The Euphrates and Tigris run parallel to each other The land between the Euphrates and the Tigris is known as Mesopotamia, which means "between the rivers" in Greek The Euphrates and Tigris rivers get to be more that 100 mi. apart and join in southeastern Iraq to form the Shatt al Arab, which empties into the Arab Gulf.

7 Turkey: The construction of dams on the river has greatly reduced fresh water inflow that would dilute pollution The Southeast Anatolia project involves the construction of 22 dams and 19 power plants by Turkey s 22 dams and 19 hydroelectric power plants will significantly decrease the amount of water to reach Syria and Iraq. Iraq: must contend with high salt content in the Euphrates as a result of leaching and chemical applications in upstream areas. The optimum use of water quality is being hindered by Turkey s dams Syria: is also using too much of the river s water

8 The Euphrates and Tigris rivers in southeast Turkey have been the primary sources of irrigation and drinking water for Syria and Iraq for thousands of years. If the GAP is ever fully realized, Up to 50% of the river water will be used within the Turkish borders. Quality of water is expected to deteriorate due to water waste from larger cities, which are located in upstream of the planned reservoir, and from developing agro-industrial irrigation in Turkey.

9 Concerns among people in Syria and Iraq with regards to the implementation of the GAP are not farfetched. But also if the Ilisu dam (138-meter high and 45 km around the Syrian-Iraqi border, which would be the largest in the Tigris River Basin, and other planned irrigation works in the Tigris Basin will drastically affect millions people along the Tigris in Iraq, including approximately four to five million people in the marshlands in southern Iraq that depend almost entirely on the rivers for their water supply.

10 In the Nile Basin, the Nile River is fed by the monsoon dominated Ethiopian highlands and the equatorial Lake Victoria. The discharge from the Ethiopian highlands peaks at a different period from July to September than runoff from Lake Victoria, which has two peak periods a long one in March to May and a less intense one from October to December (Conway 2005). These staggered seasons have to a large extent stabilized runoff patterns in the region. Prior to the construction of the Aswan High Dam, however, Egypt was exposed to several devastating floods and droughts. The dam has drastically reduced multiyear fluctuations, but was drawn down to alarmingly low levels as a record-breaking, severe drought extended from The drought was mainly attributed to a drastic reduction in precipitation over the Ethiopian highlands associated with an El Niño event (Conway 2005).

20 ARAB REGION 3.c. Drought Vulnerability the literature describes the relationship between vulnerability and capacity in two ways, which are not mutually exclusive (Bohle, 2001 ; IPCC, 2001; Moss et al., 2001 ; Yodmani, 2001 ; Downing and Patwardhan, 2004 ; Brooks et al., 2005 ; Smit and Wandel, 2006 ; Gaillard, 2010 ): 1) Vulnerability is, among other things, the result of a lack of capacity. 2) Vulnerability is the opposite of capacity, so that increasing capacity means reducing vulnerability, and high vulnerability means low capacity.

21 Path way from Hazard to Vulnerability

22 Main Steps for Assessing Vulnerability could be Ordered as Follows: Step 1: Step 2: Step 3: Step 4: Step 5: Step 6: Assessing The Main Economical Capacity Characteristics of the Studied Countries. Assessing The Main Population Capacity Characteristics of the Studied Countries. Assessing The Main Land Use and Water Availability Capacities Characteristics of the Studied Countries. Assessing the Main Water Availability and Water Use Capacities Characteristics of The Studied Countries. Ranking Countries According to Their Overall Resilience Capacities. Identifying the most ADH Vulnerable Countries and describe their Degree of Affection by ADH in Rainfed Agriculture, Rangelands, Forestry, Land Degradation.

23 Step 1: Assessing The Main Economical Capacity Characteristics of the Studied Countries. Countries main economical capacity characteristics were selected for the study are: EcA. GDP in Million US$. EcB. GDP Growth rate. EcC. NGI US$. EcD. Agriculture Share In GDP %. EcE. Labor Force % in Agriculture. EcF. Unemployment Rate %. EcG. Below Poverty Line %. EcH. Agriculture, value added per agricultural worker (USD) EcI. Evaluation of the Value of Total Agriculture Production and Food Production Value (millions of in ($). EcJ Change in crop production value per ha %

24 Step 2: Assessing The Main Population Capacity Characteristics of the Studied Countries. PoA. Mean Population Density person/km 2 PoB. People in working age (15-64) years %. PoC. Population growth rate. PoD. Net migration rate: for each 1000 person. PoE. Females % of Labour force in Agriculture PoF. Average Agriculture population Change %.

36 The Arab awakening was driven not only by political and economic stresses, but, less visibly, by environmental, population and climate stresses as well. If we focus only on the former and not the latter, we will never be able to help stabilize these societies.
