This phenomenon could be examined from different perspectives – meteorological, hydrological, agricultural and economic. Meteorological drought: It is a period (months or years) during which moisture supplied to soil or air falls below average. In other words, meteorological droughts occur when precipitation levels drop below the long-term average and temperatures rise above long-term averages. In this type of drought the relative decrease in precipitant is more 35%. Hydrological drought: This type of drought occurs when the flow of rivers and volume of stored water (the lakes behind dams as well as natural lakes) falls below the long-term average. A fall in precipitation would generally result in hydrological drought. A 50% deficit in the monthly flow of a river compared to its average flow would amount to a hydrological drought. Agricultural drought: these types of drought occur when the amount of soil moisture is incapable of providing required vaporisation to plants and agricultural products. Such periods of drought occur following meteorological or hydrological droughts during the growth season. The improper temporal distribution of precipitation could lead to agricultural drought. Economic drought: This type of drought is a function of the physical processes associated with the impact of drought on man’s economic activities. It occurs when the supply of water cannot meet a region’s basic needs for water. In actual fact, it arises when all the preceding forms of drought occur simultaneously, which is a characteristic of crisis regions. This report seeks to examine and analyse the drought hitting the country during the two-year period of 1998-2000 and present a general profile of its water resources along with the challenges facing the different regions. A look at the state of precipitation in the drought period The average precipitation across the country since the start of the current water year (1999-2000) up to April 10 has amounted to 131.9 mm. Table 1 presents the statistical data on precipitation since the water year 1968-69. As shown in the table, this amount of precipitation for the first 7 months of the water year was the lowest compared to the amount received during the corresponding period in the preceding 31 years for which statistical data is available. The precipitation in this 7-month period shows a 52% decline relative to the long-term average and a decline of 23% from a year earlier. The graph depicting the year to year variations (Figure 1) and the moving mean (Figure 2) of the precipitation for the first 7 months of the water year of 1968- 69 up to the water year of 1999-2000 (according to table 1) indicate the intermittent occurrence of dry and wet periods at 8-year intervals. 39 The Drought Situation in the Islamic Republic of Iran UN Mission Report, August 2000 A glance at the snow coverage during the drought period The state of precipitation across the provinces from late September of the water year of 1998- 2000 to mid-April as compared to the long-term average of the past 31 years is contained in table 3. Statistical data relating to the snow-fed water basins of Jajroud, Taleqan, Kordan, Lar and Haraz, Karoon, Dez, Zayandeh Roud, Qezel Uzan, Talar, Tajan, Haraz, Siah Kooh, Alvand, Karand, Qeshlaq, Kashaf Rood, Atrak, Kor and the Orumiyeh Lake show that the amount of snow was 1.5 to 2 times more than the amount received in the previous year. The maximum water- equivalent of snow in the year 1999-2000 in the water basin of Jajroud was 317 mm, while the basins of Abar Kooh and Siah Kooh received a minimum amount of 30 mm. According to the report presented by the State Meteorological Organisation, the country’s temperature in April of the said year increased relative to the same month a year earlier, causing premature melting of the snow and a considerable increase in the flow of the rivers compared to the previous year. This meant that the snow coverage in the mountains was lost within an unusually short period. A look at the state of the country’s surface waters during the drought period The surface water flow in the three-month period of January 20 to April 19 show a substantial decline relative to the long-term average. In the 30 days from January 20 to February 18 the least decline equal to – 45% occurred in the water basins of the Persian Gulf and the Sea of Oman, while the most declines at – 87.2% was in the water basin of the Orumiyeh Lake. In the 30 days from February 19 to March 20 the least fall of – 64% was in the Markazi water basin, while the most at – 93.6% occurred in the water basins of Hamoon and Sarakhs. From March 21 to April 19 the corresponding figures related to the water basins of the Persian Gulf and the Sea of Oman at – 41.2% and – 98.2% respectively.
