  2. 2.  Total land area is 164.8 mil. ha. About 18.5 mil. ha. are usedfor agriculture: 6 mil. ha. (irrigated): 32.4% 6 mil . ha. (rainfed) : 32.4% 4.5 mil. ha. (fallow) : 24.4% 2 mil. ha. (hort. crops): 10.8% Wheat and Barley:the two major crops Average Wheat Growing areas: 6.7 mil. ha Irrigated wheat: 2.7 mil. ha Rainfed wheat: 4.0 mil. haIntroduction
  3. 3. • Iran is generally known of arid andsemi-arid climate (94.1% based onUNESCO Approach) except forCaspian Sea region.• The average precipitation of thecountry (247 mm) is about half of Asia(480 mm) and one third of the world(850 mm).Climate

  9. 9. Structure of Water in Iran The two Ministries of Energy and Agriculture are currently waterThe two Ministries of Energy and Agriculture are currently wateradministrators in Iranadministrators in Iran There are several water relevant research institutes (e.g. AERI ,There are several water relevant research institutes (e.g. AERI ,SWRI in Ministry of Agriculture or TAMAB in Ministry of Energy),SWRI in Ministry of Agriculture or TAMAB in Ministry of Energy),research centers, water departments in the Universities, andresearch centers, water departments in the Universities, andConsultant Engineers Companies (private sector) (e.g. Mahab-eConsultant Engineers Companies (private sector) (e.g. Mahab-eGhods) also have an important role in this regard.Ghods) also have an important role in this regard. A number of duties of Ministry of Agriculture on soil and water issues are:A number of duties of Ministry of Agriculture on soil and water issues are: Integrated study of basins (watersheds)Integrated study of basins (watersheds) Land consolidation, on-farm improvements, and infrastructureLand consolidation, on-farm improvements, and infrastructureactivities in farms and orchards for efficient use of agricultural inputs,activities in farms and orchards for efficient use of agricultural inputs,especially waterespecially water Management of water delivery in tertiary and lower order irrigationManagement of water delivery in tertiary and lower order irrigationcanals and their O&M activitiescanals and their O&M activities Study and execute small scale water supply development projectsStudy and execute small scale water supply development projects(following permission of Ministry of Energy)(following permission of Ministry of Energy)
  10. 10. For optimum use of water allocated to the farmers,the following policies are considered:• Control of water resources and volumetric allocation of water to the farms.• Based on the established law, water charge of the regulatedsurface water is between 1-3% of value of the cultivated crops• water pumping from groundwater resources must be in accordance with thecrop water requirement and proposed cropping pattern in each region.• Subsidizing policies for water charging and supervision chargingfor farmers who their yields are higher than average.• Termination of water allocation to the farmers who in two successive yearsconsumed water more than permissible level.• Encouraging policies for the farmers who use less water andmaintain their production in reasonable level using propermanagement practices.
  11. 11. Attaining wheat selfsufficiency in the contextof securing food securityat national levelCase study
  12. 12. Importance of wheatWheat is the major crop in the country, where it is grownon 6.7 million hectares. Irrigated wheat covers one-third ofthe total wheat area but accounts for more than two-thirdsof the total wheat production.Iran has attained self-sufficiency in wheat production forthe first time since past 40 years during the 2003-2004.This testifies the successful adoption of effective soil andcrop management practices combined with improvedcultivars for increasing the welfare of rural communities indry areas of Iran through the sustainable use of land andwater resources. The participation of farmers, researchers,and extension workers in the testing, demonstration anddissemination of improved technologies has led to betterawareness of the technology and to its adoption by a largenumber of farmers.
  13. 13. Reasons for attaining self sufficiencySelecting right strategies by:1- Preparing road map through contributing all involvedrelevant policy makers, experts and researchers2- Integrated agronomy, crop breeding and policies3- Releasing of high yielding varieties4-Considering of Water Use efficiency & Waterproductivity5- Pressured irrigation systems.6- Drought tolerance varieties7- Adoption of Conservation Agriculture8- Guaranteed price for wheat market
