Notes:
1) Data from World Resources 1996-97 (WRI, 1996). 2) Data for the following countries (maximum 21), when available, were included in the above table: Afghanistan, Bahrain, Iran, Iraq, Israel, Jordan, Kazakstan, Kuwait, Kyrgyz Republic, Lebanon, Oman, Pakistan, Qatar, Saudi Arabia, Syria, Tajikistan, Turkey, Turkmenistan, United Arab Emirates, Uzbekistan, and Yemen. 3) Country-by-country data are presented in Annex D.

Annual water consumption in the region is 1,710 m³ per capita, compared with the world average of 645 m³ per capita. In many countries, the dominant water use is for irrigation to support small-but economically important-permanent pasturelands and croplands. The fraction of available water that is withdrawn annually for consumption varies from as little as 10% in Syria to, effectively, more than 100% in countries heavily reliant on desalinization.

The region is heterogeneous in terms of the countries' economies. Because it includes some of the richest and some of the poorest countries in the world, regional average economic performance statistics are misleading (IPCC 1996, WG II, Section 13.7). Industry and services contribute 82% of the gross domestic product (GDP), and agriculture accounts for the remainder. Per capita GNP has fallen substantially over the past decade, in part as a result of declining oil prices and political disruptions (IPCC 1996, WG II, Section 13.7).

7.2. Regional Climate

Two-thirds of the region can be classified as hot or cold desert. In the northern part of the region, a steppe climate prevails, with cold winters and hot summers. A narrow zone contiguous to the Mediterranean Sea is classified as a Mediterranean zone, with wet and moderately warm winters and dry summers. Permafrost zones exist in high mountain areas in the southeast part of the region.

7.2.1. Observed Temperature and Future Projections

Temperatures in the region range from -10�C to 25�C (January) to 20�C to >35�C (July) (Oxford World Atlas, 1994). The observed change in annual temperature in the region from 1955-74 to 1975-94 was 0.5�C (IPCC 1996, WG I, Figure 3.4). Temperature changes were smallest in December-February (0 to -0.25�C) and largest in September-November (~1�C). Annual temperatures in most of the Middle East region showed almost no change during the period 1901-96, but a 1-2�C/century increase was discernible in central Asia (based on the 5�x5� grid; see Annex A, Figure A-2). There was a 0.7�C increase during 1901-96 in the region as a whole (see Annex A, Figure A-9).

Climate models that include the effects of sulfate aerosols (GFDL and CCC) (IPCC 1996, WG I, Figure 6.7) project that the temperature in the region will increase 1-2�C by 2030-2050. The greatest increases are projected for winter in the northeast and for summer in part of the region's southWest (IPCC 1996, WG I, Figure 6.10).
