1 LOGO The Role of Irrigation in Agricultural Development and Poverty Alleviation at Rural Community of Iran 1523 October 2011, Tehran, Iran Presented By: Enayatollah Farahani 2 Introduction Historically, Iranian agricultural activities which started with rainfed cereal are over than 8 Thousand years old. At the present it is extended to a wide variety of agricultural products. Climate and Agriculture of Iran Iranian territory is located at a semiarid and deserted area except for a small area at north and northeastern part of the country. The average precipitation throughout the country is about 256 mm, consequently agriculture of Iran is strongly dependant on water resources and its development is tied to the development which in turn depends on construction of water works and utilities. Tables (1) & (2) show the climatic conditions and rainfall of Iran. 1

3 5 Definition of poverty Poverty or wealth of a country depends strongly on the balance between production and population rates. These conditions have been prevalent in recent decades in countries in general and in Iran particular. In most developing countries including Iran, due to climatic conditions and scarce rainfall and shortage of water resources, the maintenance and optimum consumption of these resources have a crucial part in poverty alleviation in rural communities. Fortunately, Iran has a good record in this field. Iran during the half past century has established vast number of hydraulic utilities and water works so that the amount of water allocated to agriculture sector has increased from billion cubic meters in the year 1340 to 82 billion cubic meters in recent years. It is worthwhile to mention that between years 1981 to 1991 the rate of population growth reached 4 percent, this rate in recent years has fallen to 1.20 to 1.40 by applying birth control programs. The effect of these changes are presented in Tables (3) 6 Table(3)Change of population rate, water use for cropped area & production ( ) Description Population (million people) Agricultural water consumption (billion m3) Irrigated cropped and orchard area (million ha) Total water production (million Ton) Corn production from water produced (million Ton) Total production from rain fed & irrigated farms

4 7 Per capita Agricultural Production and water Consumption The water consumed for agricultural l production per capita, during the last half century, despite population increase from 24 million people to 73 million people, has a little fluctuation due to water resources development projects, However with regard to gradual technological developments, production of irrigated crops and orchards has been increased from 297 kg to 1055 kg per capita. The share of irrigated cereal also has increased about two times despite tripled population. Also total amount of rainfed and irrigated crops per capita changed proportionally. These changes are presented in table (4). 8 Table (4) Water consumption and agricultural production per capita Description Population(Million) Agricultural water consumption per capita (m3) Irrigated products per capita (Kg) Total rainfed & irrigated products per capita Irrigated cereal production per capita (Kg) Irrigated & rainfed cereal production per capita (Kg)

5 9 Optimal Use of Water Resources to Struggle Against Poverty Available water resources in Iran permit maximum allocation 100 million cubic meter of water to the agricultural sector. In this case about 10 to 11 million ha. of irrigated cropped areas and orchards could be irrigated. On the other hand population will amount to about 90 million in 2025 and continues to grow respectively with the present rate. Table (5), show average water consumption per hectare and the proportion of growth production cubic meter of per water consumption in recent decades. 10 Table (5)Average water consumption per capita & crop products Description Water Consumption(Billion M3) Irrigated Farms & Orchards (Million ha) Crude product/water consumption (kg/m3) Average water consumption (M3/ha) Estimated country's out look program for development.

6 11 Fight Against Poverty Irrigation & civil works Necessary But Not Enough reducing average water consumption per hectare increasing crude production per cubic meter of water consumption, 12 Fight Against Poverty More Important t Than Irrigation Better management of available resourses Look for technical solutions that work within a clearly defined socioeconomic context so that they can be mobilized in a case specific approach 6

11 21 Fight Against Poverty A Proper Pattern New Existing farming joint Stock cooperative Sahl Abad Khooshab Sib Chah Mehdi Abad 22 Sahl Abad Farming Joint stock cooperative Location of Selected Pattern The selected area for development of SahlAbbad and Firooz Abbad villages is located at SahlAbbad plain of Nahbandan province of Southern Khorasan in Iran. (The attached map)this area is in poor and limited conditions from the view point of climate, land and water resources. 11

12 23 Sahl Abad Farming Joint stock cooperative Location 24 Sahl Abad Farming Joint stock cooperative Land Ownerships and Social Structure The population in SahlAbbad and FiroozAbbad villages is 454 persons in 117 families, of which 92 families are economically active. From economical point of view residents can be classified as: operators, owners of agricultural farm lands operators, owners of water & land operators, owners of water residents without water & land resources From land ownership point of view, %26 own about 13 ha., %7 own about 35 ha. %5 own 510 ha, %46 own about 1050 ha. & %16 own about ha. However limited available water resources is not proportional to the lands ownership and in fact many of these families struggle with poverty. 12

13 25 Sahl Abad Farming Joint stock cooperative Water & Soil Resources Total land area of SahlAbbad and FiroozAbbad village is more than 2000 ha. The area of these villages is 700 ha. of which only half is under cultivation. The water resources of these lands consist of two Qanats and 13 wells with the irrigation capacity of approximately 440 lit/s, which due to economical problems, about 300 liters of this capacity is used with low efficiency. 26 Sahl Abad Farming Joint stock cooperative Development Studies and services Studies and development services of This area include the following : Pedology studies Recognizing limits and capacities of development Engineering services and land consolidation of farm lands for an area of 740 ha Appropriate combination of water resources in line with improving irrigation methods and increasing irrigation efficiency. Integrating g farm land as favorable economic units Executing development projects. Organizing operational system under a farming joint stock cooperative. 13

14 27 Sahl Abad Farming Joint stock cooperative Irrigation methods and the efficiency of water use Irrigation methods before executing the project were generally flood irrigation and in some cases Border Irrigation and the efficiency estimated to be %33. In development plan, while utilizing the capacity of water resources and considering local conditions, localized irrigation method is selected to irrigate farms and drip irrigation method for orchards. Localized irrigation is among pressurized irrigation methods which does not completely moisten soil surface but only moistens that part of soil where the root is located. In this method evaporation from soil surface reduces to the minimum and runoff losses becomes zero, thus irrigation efficiency increases to %65% Sahl Abad Farming Joint stock cooperative Cropped Area & Production By implementation of the project and developmental services ( ), the cropped area and production rates have changed as shown in the table (6). 14

Production costs include seed, fertilizer services, machinery services, water supply and distribution costs and miscellaneous services, and at last, the manpower and wages. After executing the project, machinery services expanded, agricultural services developed, and lands were exploited in favorable economic units by applying integrated management.
