AWATT operates active projects in the provinces of Balkh, Herat, Kabul, Kapisa, Kunar, Laghman, Nangarhar, Paktiya, Paktika, and Parwan. It is also exploring opportunities through watershed forestry assessments in Bamiyan, Khost, Wardak, and Zabul. AWATT works with Ministry of Agriculture Irrigation and Livestock (MAIL) staff and agricultural extension workers to provide outreach support to isolated farmers in far-flung communities. Funding of the AWATT Program is from the U.S. Government through a cooperative agreement with USAID-Afghanistan’s Office of Agriculture. New Mexico State University (NMSU) in collaboration with Colorado State University (CSU), Southern Illinois University Carbondale (SIUC), and the University of Illinois at Urbana-Champaign (UIUC) leads the Afghanistan-based AWATT team. AWATT and USAID signed the cooperative agreement on March 3, 2008. AWATT BALKH WATERSHED DIAGNOSTIC ANALYSIS In June 2009, AWATT team members ran a training and research program with representatives from various stakeholder agencies. Team members included Eng. Hakeem Khan, AWATT incountry water resources specialist, Dr. Stephen Davies, Dr. Chris Goemans and Dr. Ramchand Oad of Colorado State University, and Dr. Jamal Khan from the University of Peshawar. A group of 30 officials from the Ministry of Energy and Water (MEW), the Ministry of Agriculture, Irrigation and Livestock (MAIL), and other Government and nongovernment organizations of Afghanistan participated in a two-week intensive Diagnostic Analysis (DA) of irrigation systems in Mazar-e-Sharif and the Balkh watershed. (Annex 1 lists the participating ministries and agencies.) The DA reviews water resource management in Afghanistan in order to determine AWATT’s requirements for the year ahead. The program included a combination of in-class work, demonstrations of water measurement techniques, and a farm survey. Over the first three days, AWATT presented background information about water management issues, crop water requirements, and farm economics to participants for discussion. Further presentations examined the implications of new water laws, the role of the Mirab, crop water requirements, and overall operation and management of irrigation systems. Site visits by participants to the Nahr-e Shahi and Mirzae canal intakes took place to examine and compare flow control and division structures along the canals. Annex II presents a full schedule of topics covered in the workshop. Afghanistan Water, Agriculture and Technology Transfer Program 7 AWATT Balkh Watershed Diagnostic Analysis Report This study measured irrigation water supply in the Siagard, Mirzae, and Balkh canals in Mazar-eSharif, Balkh Province and observed crop water demand and agricultural trends. An overview of major water flows using primary and secondary data describes the Balkh Watershed. The study also compared estimates of the water requirements of various crops with findings relating to water availability throughout the year. The DA reviews results in relation to agricultural and livestock practices and identifies water flow and losses in the three samples canals. The report presents the main findings on water supply and management practices in the Balkh River Basin and contains results of the survey conducted as part of the program. Participants and authors of this document recognized the need for extensive training in the future. This and further conclusions and recommendations obtained from the participants of the program and the authors of this document are evaluated for possible inclusion in the 2010 Plan of Work. WATER SUPPLY & MANAGEMENT PRACTICES IN THE BALKH AB RIVER BASIN The Balkh Ab Watershed (Balkh Watershed) forms part of the Northern Basin of Afghanistan. Surface flows from the Northern Basin originate from the mountains of the Central Highlands and account for only two percent of the total volume of surface water flowing through the country. Afghanistan utilizes all surface water and rivers dry up either in irrigation canals or in desert sands before they can reach the northern border of the country. In 1968, Balkh province had 224,500 ha of land under irrigation. River and streams account for the majority of irrigation on this land. The Balkh River originates from Bandi Amir Lake located in Bamiyan. Data shows that flow discharge varies from 19.8 to 168 m3/s, with an average of 53.35 m3/s recorded from 1964-1978. No data is available from 1979-2007 due to conflict in the country. Flow records show that availability of water in the system has decreased by around 34.4 percent over the past three decades. During wet years, upstream users have sufficient supplies of water to be able to send excess resources downstream. Throughout average and dry years, river supplies are unable to satisfy demand. The DA shows that around one-third of water in two of the three sampled canals is lost due to poor maintenance and weed growth on sides of the canal. Estimates of the allocated and observed water shares in various tertiary channels show that the first four tertiary channels located upstream in the systems receive close to their allocated water share. The amount of water reaching the remaining tertiary canals however is significantly less. This study shows differences in water management outcomes between the head, middle and tail reaches of the canals. Survey findings indicate that cleaning of the canals occurs more frequently at the tail areas of all three sampled canals. Farmers at the tail end of the canals also spend more time cleaning the watercourse. The survey also showed that farmers with the least amount of water are most likely to irrigate at night, suggesting possible cases of water theft in areas where water resources are insufficient. Afghanistan Water, Agriculture and Technology Transfer Program 8 AWATT Balkh Watershed Diagnostic Analysis Report CROP WATER DEMAND AND IRRIGATION SUPPLY Knowledge of when to irrigate and of how much water to apply per irrigation is important in terms of farm production and gross farm profits, particularly in view of the country’s scarce water supplies. Over the course of FY09, AWATT’s irrigation engineers measured irrigation water supply in the three sampled canals. Average potential evapo-transpiration (ETo), rainfall, and irrigation water requirements for 11 major crops grown in the region were also calculated. This study shows that peak water demand occurs in May and June. Data shows a severe shortage of water in all of the sampled canals’ irrigation service areas, with farmers in these areas cultivating only a small percentage of their cultivable land due to lack of irrigation supplies. AWATT recommends efficient conservation and improved management of water resources, together with the introduction of improved water management practices such as raised beds, better flow control structures, and land leveling. AGRICULTURE The average landholding per household in the service areas of the sampled canals is 9.4 hectares (ha). Data shows that the majority of farmers are landowners, with insignificant producer rental land situated on the Balkh Canal. Owners represented approximately 63 percent of farmers surveyed. Tenants and owner/tenants represented close to 19 percent each of those surveyed. Data shows that landowners hold the majority of tail-end land at the Siagard and Mirzae canals. At the Balkh canal, land ownership is greater at the head-end. This study recorded no land ownership at the tail end of the canal. A study of cropping intensities showed that significant portions of landholdings are fallow due to insufficient supplies of irrigation water. Results ranged from 21.1 to 27.8 percent in the summer season and from 44.7 to 53.1 percent in the winter season. Fallow land during summer and winter seasons ranged from 72.7 to 87.9 percent and 46.9 to 55.3 percent respectively. Fallow land accounts for an average of approximately 80 percent of land in the summer and 52 percent in the winter, due to shortages of irrigation water supply and low rainfall in the sampled areas. Wheat and barley represented the major crops planted between mid-October and midNovember. Harvesting takes place during the month of June. During spring season, alfalfa, cotton, melon, watermelon, eggplant, okra, and cucumbers grow predominantly in the upstream reaches of the canals’ service areas. In the summer season maize, cumin, and sesame grow on a small percentage of the cultivated areas. In the Balkh River Basin, yields of wheat and barley stood at 20.9 million kg/ha at the head, 29.2 million kg/ha at the middle and 21.5 million kg/ha at the tail reaches of the sampled areas. In general, average yields of wheat, barley, cotton, and watermelon were higher at the middle reaches of the sampled canals than at the head and tail reaches. Findings suggest possible overirrigation at the head-end and under-irrigation at the tail end of the sampled canals. Yields of melon were significantly greater at the middle and tail reaches due to the low water demands of Afghanistan Water, Agriculture and Technology Transfer Program 9 AWATT Balkh Watershed Diagnostic Analysis Report the crop. Results also showed that farmers producing the most profitable crops such as wheat, melon, watermelon, and those farming on better-irrigated land had more contact with MAIL Extension service agents. CONCLUSIONS AND RECOMMENDATIONS Water is a scarce resource in Afghanistan’s semi-arid climate. If not properly allocated, farmers will face inevitable heavy water shortages. Findings from this DA show that farmers located at the head of the canal are less likely to face scarcity issues, while the farmers in the tail areas are most susceptible to water shortages. Equitable water distribution is unlikely due to physical, management, socio-cultural, political, and financial constraints. With better management, water resources at the head reaches of the canals can be preserved and used to irrigate more areas situated in the downstream reaches of the system. Results of this DA show that improved maintenance and proper weed control would help to reduce loss and offer more efficient conveyance in the canal system. However, the condition of canal infrastructures and distribution and management systems are not at a level to ensure equitable water distribution without major improvements. Of the farmers surveyed approximately 59 percent of respondents said they were not satisfied with water supply. Some respondents described the overall maintenance of the distribution system as less than adequate. Others cited the need for major improvements in canal design and flow regulation and distribution structures. Less than one third of land is cultivated each year due to water shortages. The promotion of more judicious and improved management of water supply in the canals through capacity-building initiatives for all stakeholders is crucial. There is a clear need for conservation and better management of water resources in the area. Implementation of improved water management practices, such as raised beds, improved flow control structures, and land leveling, will promote better water conservation in the area, and collaboration between all basin water users and stakeholders will promote understanding between upstream and downstream water users. Upstream users should be encouraged to reserve some water resources for use by downstream users. Strengthening of the MAIL Extension Service will improve the transfer of new technologies to farmers. Strengthening of Water Users Associations should also be encouraged. Fluctuations in water supply are apparent due to variations in yearly precipitation and rainfall. Climate change may also contribute to more fluctuations in water availability in the river systems in the future. Construction of a water reservoir to conserve flood water and provide a sustainable water supply to the Balkh River Canal system should therefore be explored for use during water shortage periods. Online and farm storage systems should be assessed in line with water availability and use in the Balkh River Basin. Afghanistan Water, Agriculture and Technology Transfer Program 10 AWATT Balkh Watershed Diagnostic Analysis Report Water shortages could also be tackled and agricultural productivity enhanced through the conjunctive use of surface and ground water. Water saving technologies can also prevent losses. Having a sound policy framework, including effective price policies for agricultural input and output is the key to developing a successful and vigorous natural agricultural sector. While disease and insect infestation remains a great problem for farmers, the prohibitive cost or non-availability of quality seeds, insecticides, fertilizers and farm machinery were also cited alongside flaws in the MAIL Extension Service. Those surveyed also called for greater and improved access to transportation and market facilities, veterinary services and bank loans for small farmers, as well as the strengthening of farmer organizations and the development of demonstration plots. In order to increase agricultural production, productivity, and income, technical training should not limited to agricultural issues. Farmers must be able to understand the concepts of cost and return analyses and net profit and loss. An effective marketing system would also allow farmers to ensure a sustainable income from their land. Afghanistan Water, Agriculture and Technology Transfer Program 11 AWATT Balkh Watershed Diagnostic Analysis Report SECTION I: WATER SUPPLY MANAGEMENT PRACTICES IN THE BALKH AB RIVER BASIN OVERVIEW OF THE BALKH AB WATERSHED The Balkh Ab Watershed (Balkh Watershed) is part of the Northern Basin of Afghanistan. The Northern Basin surface flows come from the mountains of the Central Highlands and account for only two percent of the total surface water volume flowing through the country. Afghanistan utilizes all surface water and rivers dry up either in irrigation canals or in desert sands before they can reach the northern border of the country. Because of this hydrological oddity, there is a non-drainage area along the northern border of the Balkh province, and thus, aside from possible underground movement of water through aquifer recharge, the watershed is closed. The Balkh Watershed is the largest watershed in the Northern Basin. It is centrally located along the northern border of the country and is primarily rain and snow fed. There are, however, two prominent springs in the Balkh River Valley. Both springs drain into the Balkh River and flows utilized downstream. The Balkh Watershed, which covers 28,835 sq. km, drains approximately 87 percent of river flows in the Northern Basin. There are approximately 1,600 settlements in the watershed with a total population exceeding 1.3 million. Figure 1.1 shows the location of Balkh province and the Balkh Watershed within Afghanistan and relative to surrounding countries. In 1968, Balkh province had 224,500 ha under irrigation, the majority through surface water from river and stream sources. The Balkh River originates from Bandi Amir Lake located in Bamiyan and has a total length of 400 km with a watershed area of 18,700 km2. Flow discharge figures recorded from 1964-1978 range from 19.8 to 168 m3/s, with an average of 53.35 m3/s. No data is available from 1979-2007 due to conflict in the country. The livelihood of 114,883 Balkh Province inhabitants depends on agriculture and livestock (FAO, 1996). The Government of Afghanistan built the Nahr-e Shahi Canal system, which begins at the southern edge of a prominent alluvial fan in the Balkh province (Figure 1.2), to facilitate irrigation. From the Balkh River, 18 main intakes supply water to 18 canals, providing approximately 50,000 ha with irrigation water. This figure represents close to one quarter of the irrigated land in the watershed. While the exact route of the canal remains unmapped, a detailed schematic of the canal is available. A non-drainage area exists above the three watersheds. The alluvial fan of the Balkh Watershed is central and prominent. The Khulm Watershed, fed by the Samangan River shows a similar feature. Afghanistan Water, Agriculture and Technology Transfer Program 12 AWATT Balkh Watershed Diagnostic Analysis Report Figure 1.1: Location of Balkh Province Watersheds Figure 1.2: The Nahr-e Shahi Canal and the Alluvial Fan Along the Balkh River Afghanistan Water, Agriculture and Technology Transfer Program 13 AWATT Balkh Watershed Diagnostic Analysis Report BALKH AB RIVER FLOW Records show that from 1964-1978 water flow from the Balkh River at Rabat-i-Bala ranged from 19.8 to 160 m3/s (Figure 1.3). Over the past three decades, average flow has decreased by approximately 34.38 percent. No data is available from 1979 to 2007. Figure 1.3: Flow of Balkh River at Rabat-i-Bala from 1964-1978 (Source: Afghan Government Central Statistics) With no reservoir in the Balkh River system, canal intakes come directly from the river. The amount of water diverted to canal systems varies according to the availability of water in the river system. During the winter months, snowfall occurs in the upper mountains of the Balkh River Basin. Increased temperatures at the end of the winter season result in increased river flows (Figure 1.4). Highest flows were recorded from May to August and lowest flows from November to February. The Balkh River’s annual average discharge is 53.35 m3/s, with the highest recorded discharge of 1,430 m3/s observed in May 2009. While the flood duration of the river ranges from just one to three days, variations in the river flow levels influence the water supply of the canal system. Management of the system becomes more difficult because of siltation and lack of head regulating structures. Figure 1.4: Variations in Relative Water Levels of the Balkh River, February 2008 to May 2009 (Source: MEW, Mazar-e-Sharif) Afghanistan Water, Agriculture and Technology Transfer Program 14 AWATT Balkh Watershed Diagnostic Analysis Report MEASUREMENT OF STREAM FLOWS AND WATER USE Figure 1.5 shows a number of stream gauges located along the Balkh River. Gauges measured daily flow rates from 1969-1978, although intervals varied between gauges. In order to gain some insight into water use along the Balkh River, our study incorporates water flow information from four of these stations. Stream flow analysis comprises data from the Darya Suf and Rabat-i-Bala river stations. The Darya Suf River gauge is located below the settlement of Shulgareh, an irrigation intensive community. Findings from this study show that inhabitants at Shulgareh use large quantities of water to flood irrigate their rice fields. However, the location of this gauge is under dispute and such observations should not form the basis of any analysis. The Rabat-i-Bala gauge is located below the Darya Suf River gauge. Figure 1.5: Satellite Map of the Sampled Areas Figure 1.6 indicates that peak flows occur in June in average or wet years. In dry years, peak flows occur in May. A downstream peak occurs because users upstream divert large volumes of in order to satisfy demand during the summer months. In wetter years, demand from users upstream is satisfied, with excess water flowing downstream and resulting in peaks in June. Afghanistan Water, Agriculture and Technology Transfer Program 15 AWATT Balkh Watershed Diagnostic Analysis Report Figure 1.7 suggests that gauges situated at the Darya Suf and Rabat-i-Bala rivers observe peak flows at the same time, typically in May. Figure 1.6: Monthly Flow Volume of Rabat-i-Bala Figure 1.7: Monthly Flow Volume of Darya Suf River Afghanistan Water, Agriculture and Technology Transfer Program 16 AWATT Balkh Watershed Diagnostic Analysis Report Figures 1.8, 1.9, and 1.10 show the distribution of average flows as a percentage of the total for all years, wet years, and average years respectively. During wet years, users upstream have sufficient water supply to be able to send excess water down river. However, during average years there is not enough water in the river to satisfy demand and water use upstream results in changes in the seasonal volume and a reduced supply of water downstream.

The workshop management team developed a detailed questionnaire and surveys conducted on random farmers located in the upstream, midstream and downstream reaches of the sampled canals. The survey sought to acquire feedback from farmers on the following issues: Water availability Water management Water losses Water distribution Role of the Mirab Canal maintenance Cropping patterns Farm budgets Marketing Plant protection issues Livestock Table 1.1 shows salient features of the sampled canals studied during this DA process.

Seven canals serve the Shogara Valley area. The dominant cropping pattern is rice-wheat. The Hazdha Nahr irrigation network serves an estimated area of 424,880 ha through a system of 11 separate canals. The network covers a total length of 475 km across Mazar, Balkh, Aqcha, and Jawzjan regions (Lee, 2003). Allocation rights form the basis of water allocation, expressed in a unit known as the paikal, where one paikal is equal to 360 to 400 jeribs or 72 to 80 ha. An agricultural taxation system stipulates water rights (ADB, 2002). Table 1.2 shows the service areas of the irrigation canals of the Balkh River system, which range from 5,040 to 79,200 ha, with an average of 34,383 ha.

Losses were determined by observing in-flows and out-flows using constructed weirs and gauges in the system. This study measured water at the beginning and end of each reach. The loss is the difference between any offtakes, such as flowing watercourses. A summary of results presented in Table 1.3 shows that the estimated conveyance losses in the three sampled canals ranged from 0.85 to 31.67 percent per km. Overall losses in the whole length of the canals were calculated at 33.85 and 30.14 percent in Siagard and Mirzae canals respectively. This study concludes that approximately one-third of water is lost in the whole length of the canal due to poor maintenance and weed growth on the sides of the canal. Lining certain sections of the canal where water losses are relatively high can result in significant water savings. However, this can be prohibitive in terms of cost. Better maintenance and proper weed control would also help to reduce loss and provide more efficient canal system conveyance. Time constraints and limited resources do not allow for a comprehensive evaluation of canal water losses within this DA. The subject could form the basis of a separate study. Many variables can affect results and a few quick measurements may not compensate for them. Losses in unlined channels are a function of the wetted perimeter; this coupled with the daily changes in channel water levels make it difficult to derive estimates of losses in a short period. Soil conditions of the channel can also affect results. Only a program that can take sufficient measurements over time and changing conditions can provide precise data. Thus, results shown in this study are indicative values only and may be subject to changes in the flow and maintenance conditions of the canals.

Figures 1.11 and 1.12 illustrate farmers’ responses to the question: “How often is your watercourse cleaned?” Afghanistan Water, Agriculture and Technology Transfer Program 20 AWATT Balkh Watershed Diagnostic Analysis Report Results show that the majority of farmers do spend time cleaning the canal and see value in this activity. Figure 1.11 shows the significant differences in watercourse cleaning frequency across canals. Siagard is the only canal in which some farmers (more than 20 percent) reported never having cleaned the canal. Balkh has the greatest percentage of farmers who clean the canal more than once per season. These differences across canals could be due to canal size. Theoretically, a canal with a smaller group of farmers and a greater likelihood of a more homogenous population would have more incentive to clean the canal, as they are likely to be more accountable to others in the community. Outside research also indicates that the closer the canal is to a market, the less likely the individuals at the canal are to cooperate. Figure 1.11: Frequency of Canal Cleaning By Canal Figure 1.12: Frequency of Canal Cleaning By Location in Canal Figure 1.12 shows watercourse cleaning frequency across the head, middle, and tail reaches of the canals. The data shows that the head and middle areas are similar in terms of cleaning Afghanistan Water, Agriculture and Technology Transfer Program 21 AWATT Balkh Watershed Diagnostic Analysis Report frequency. On average cleaning of the canal is most frequent in the tail areas. Figures 1.13 and 1.14 show the number of person-days spent cleaning the canal each season. The results indicate that not only is the tail cleaned more frequently but that more person-days are spent cleaning the canal. This result corroborates with expectations that those living in the tail areas with higher marginal values of water have the greatest private incentive to clean the canal. Figure 1.13: Average Person-Days Spent Cleaning at the Head, Middle and Tail Reaches of the Canal Figure 1.14: Percentage of Days Spent Cleaning the Canal NIGHT IRRIGATION The survey also compared irrigation practices during the day and night. Figure 1.15 indicates that farmers at the head reaches are less likely to irrigate differently at night to those located at the tail reaches of the canals. Findings from the DA show that farmers with the least access to water resources are more likely to irrigate differently at night. This might lead us to conclude that cases of water theft take place at night in areas where water supply is otherwise insufficient. Afghanistan Water, Agriculture and Technology Transfer Program 22 AWATT Balkh Watershed Diagnostic Analysis Report The survey also compared irrigation practices during the day and night. Data indicates that farmers at the head reaches are less likely to irrigate differently at night to those located at the tail reaches of the canals. The DA also shows that farmers with the least access to water resources are more likely to irrigate differently at night. This might lead us to conclude that cases of water theft take place at night in areas where water supply is otherwise insufficient. Figure 1.15: Differences in Irrigation Practices at Night LAND LEVELING Figure 1.16 shows that poor land leveling is most common at the Siagard Canal and nonexistent at the Balkh Canal. It also appears that the Siagard Canal has many inconsistencies with the other sampled canals, perhaps because of its much greater length. While subjective, it can be questioned whether farmers in the area are aware of their land level status. Figure 1.16: Percentage of Farms with Poor Land Leveling DURATION OF WATER APPLICATION The duration of water application applied to alfalfa crops ranged from 1.83 to 6.97 hrs/ha, with an average of 3.91 hrs/ha. In general, water application to alfalfa crops was 30 and 40 percent less at the middle and tail reaches compared to those at the head reaches. Higher application of Afghanistan Water, Agriculture and Technology Transfer Program 23 AWATT Balkh Watershed Diagnostic Analysis Report water at the upstream reaches did not result in higher yields than those in the middle reaches of the sampled canals. We can conclude that with better management, water resources at the upstream can be preserved and used to irrigate more areas at the downstream reaches of the system. Table 1.4: Water Application Practiced by Farmers in the Service Area of Sampled Canals Canal Siagard Mirzae Balkh Overall average Sample Size 16 16 27 Head Middle Tail Average Irrigation water applied to Alfalfa crop (hrs/ha) 6.97 3.00 2.92 4.30 5.08 4.79 4.27 4.71 3.41 2.95 1.83 2.73 5.15 3.58 3.01 3.91 WATER DISTRIBUTION AND ALLOCATION: ADEQUACY AND RELIABILITY Afghanistan has a semi-arid climate and water is a scarce resource. Farmers face heavy water shortages due to inefficient water allocation. Findings from the DA show farmers located at the head of the canal are less likely to face scarcity issues, while the farmers in the tail areas are most susceptible to water shortages. Three parties are involved in the management of water distribution. Each main canal has a mirab bashi (water bailiff), who is assisted by the mirab (water manager), responsible for major secondary canal intakes. At the tertiary canal level, the chakbashi (village agricultural specialist) assists the mirab bashi and the mirab. Water distribution is not equitable and many farmers in the downstream areas of the canal reported excessive use of water by upstream users. Observations suggest that rice cultivation is one of the main causes of water insufficiencies in the downstream areas of the river basin. However, the appropriateness of distribution can only be assessed using appropriate measurements. Fifteen tertiary units located on the Siagard, Mirzae and Balkh canals measured outlet discharge (Tables 1.5 to 1.7). Results show that water supply in the head reaches of the sampled canals was more efficient and in line with allocated shares compared to downstream reaches in the system. Wide variations exist downstream, with some outlets receiving less than their allocated share. The water allocation system does not consider losses, causing inequitable distribution of water throughout the system, especially at the tail end of the canals. Table 1.5 shows the allocated and observed water share in various tertiary channels in the Siagard canal system. Data from this study shows that the first four tertiary channels located upstream in the systems received close to their allocated water share, while the remaining tertiary canals received less than their allocated share. Water distribution in the Mirzae Canal was relatively better, due in part to its relatively small length compared to the Siagard Canal Afghanistan Water, Agriculture and Technology Transfer Program 24 AWATT Balkh Watershed Diagnostic Analysis Report (Table 1.6). In general, outlets at the head reaches of the sampled systems received more water than those at the tail reaches. Situated mainly at the tail end of the canal, there are five tube wells in the downstream reaches of the canal systems. The installation of tube wells in areas receiving an insufficient water supply from the canals supports responses received to similar questions relating to the efficient allocation of water. Pumping costs are higher in the tail reaches of the canals.

In the Siagard Canal service area, 85 percent of respondents reported less than enough or too little water. In the Mirzae canal, 76 percent of farmers reported sufficient water supplies (Figures 1.17 and 1.18). Figure 1.17: Survey Results of Water Adequacy during Summer Figure 1.18: Survey Results of Water Adequacy during Winter Season Afghanistan Water, Agriculture and Technology Transfer Program 26 AWATT Balkh Watershed Diagnostic Analysis Report Figure 1.19 illustrates that across the three sampled canals the head areas are likely to experience greater percentages of farmers reporting sufficient amounts of water than those in the tail areas. The tail areas do not appear to be significantly different from those in the middle of the sampled canals, but this may be due to the small amounts of middle farmers in some of the samples. However, we cannot draw any conclusions from this variable, as sufficiency is a subjective concept that depends on the type of crops grown and the expectations of the individual farmer. Figure 1.19: Survey Results of Reported Water Sufficiency A number of factors contribute to water scarcity issues and the inability of the system to provide adequate water to the farmers. These factors include: Poor maintenance which may lead to excessive losses; Seepage loss in the canals; Non-consideration of travel time in water allocation strategies and time required for sufficient water to reach the tail areas; Cultivation of high water use crop (rice) in the upstream reaches of the Balkh River Basin; and Illegal and excessive use of water by upstream users. Based on direct observation during walk-throughs and discussions with farmers, some of the problems in the Balkh Ab River’s Canal system related to water distribution include: Shortage of water in the system due to excessive use of water in the upstream reaches of the canal; Illegal obstruction by farmers to increase flows into the specific outlets; Non-consideration of canal filling and drainage time leading to non-equitable water distribution; Vulnerability of farmers to manipulation by powerful influential landowners; and Afghanistan Water, Agriculture and Technology Transfer Program 27 AWATT Balkh Watershed Diagnostic Analysis Report Tendency by some farmers and other powerful stakeholders at the head reaches to apply water during the day and to allow water to flow at night. As a result, some farmers in the tail regions engage in permanent night irrigations. WATER MANAGEMENT: THE ROLE OF THE MIRAB The village Mirab is responsible for all structures and distribution systems along the canal. Where required he collects from the users and pays for the maintenance of the canal under the supervision of the elders. The Mirab also resolves disputes over water and is responsible for arranging the cleaning of the canal at the end of each year. Generally, people taking part in the survey were satisfied with the role of Mirab. In terms of managing the irrigation system in Afghanistan, the main responsibilities of the Mirab include: Water conveyance and distribution; Major link between government and water users; Maintenance of the water system with help from the community; Collection of funds for maintenance; General care of the system; Collection and payment of funds for maintenance and operation; Dispute resolution; and Organizing annual cleaning of the canal. GOVERNMENT AND COMMUNITY CONTRIBUTIONS Traditionally, communities have excavated canals in the Balkh province, with distribution issues managed by the water users themselves. As a result, the government only contributes in the construction and maintenance of basic structures along the system. In Afghanistan, the community manages almost 88 percent of the irrigation canals, while the Government, in regions that include Nangarhar, Parwan, and Helmand, excavated and now manage 12 percent of the canals. The Government intends to take over the management issues of the traditional canals in the long term, for the purpose of preventing water loses, land loggings and salinities. In the meantime, disputes arising along the system will be resolved through the Mirab and the enforcement of new water laws. The Government will construct intakes in an appropriate way, and disputes and illegal interferences eradicated. Communities are encouraged to organize volunteer works to clean the canal or collect funds for providing services to the system. The community must be convinced of government initiatives to improve irrigation systems. The community may also participate in the solving of disputes. Afghanistan Water, Agriculture and Technology Transfer Program 28 AWATT Balkh Watershed Diagnostic Analysis Report Community initiatives may prevent water losses at the canal and on-farm levels. Activities include: Cleaning of the canal Collection of funds to provide services to system; Resolution of disputes; Water usage based on crop requirements; Introduction of new technologies; Development of water associations; Improvements to structures; and Effective maintenance. STRUCTURAL IMPROVEMENTS AND MAINTENANCE REQUIREMENTS Some respondents described the overall maintenance of the distribution system as less than adequate. Others cited the need for major improvements in canal design and flow regulation and distribution structures. Areas of maintenance fall into three major need categories: essential, priority, and annual. A particular maintenance item will fall into one of the three categories depending on the conditions of a particular canal. Respondents of the survey made the following comments concerning maintenance: De-silting of sampled canals and irrigation channels are performed once or twice per year; Maintenance funds for canals and irrigation channels are collected on the basis of land holding; Most de-silting is done manually. In the main canals the exercise requires participation from 500-600 irrigators over a 15-30 day period; and Government help is sought to carry out major repairs. Annual maintenance requirements were defined as follows: Removal of all vegetation along canal banks and embankments; Establishment of excess road along the canal; De-silting and removal of all vegetation from canal banks and beds; and Repair of damaged canal banks and/or scouring of holes at structures. For the purpose of this study, essential structural and maintenance improvement requirements are as follows: De-silting of canal and removal of weeds on the bank of canal; Installation of new permanent fixed staff gauges at appropriate locations for water measurement at all the distribution points; Necessary installation of flow regulation and distribution structures; and Afghanistan Water, Agriculture and Technology Transfer Program 29 AWATT Balkh Watershed Diagnostic Analysis Report Identification of location of structures, water distribution points and paint making systems at each 1000 m interval on the canals. MAJOR WATER ISSUES Less than one third of land is cultivated each year due to water shortages. Fluctuations in water supply due to variations in river flow also present a major challenge. Other major issues include: Lack of water control and regulation structures; Water regulating devices not installed in the intakes for determination of water rights; Weeds on the banks; Inequitable water allocation and distribution; Water shortage in the upstream as a result of rice field cultivation in the Sholgara Valley; and Illegal pumping of water. Plate 1.1: Image Showing Condition of a Section of one of the Sampled Canals Afghanistan Water, Agriculture and Technology Transfer Program 30 AWATT Balkh Watershed Diagnostic Analysis Report Most farmers lack technical knowledge of water management in the main canal systems. Some branch canals do not have basic offtakes installed, resulting in inequitable water distribution. Farmers in the upstream reaches of the Balkh River Basin in the Sholgara Valley grow rice on an area of 260-280 ha. In addition crops such as cotton, fruit trees, grapes and vegetables (FAO, 2003) are grown on significant areas of land. Rice cultivation is expected to increase due to the relatively better returns of the crop. Water users in the Sholgara Valley fail to follow intercommunity water management practices and divert water from the Balkh River when they require. Without government intervention regulation of flow is likely to continue to be a major issue in terms of effective water distribution. PERFORMANCE ASSESSMENT: CONCLUSIONS AND RECOMMENDATIONS The condition of canal infrastructures and distribution and management systems are not at a level to ensure equitable water distribution without major improvements. Therefore, in order to achieve a sustainable and fully functional canal system, AWATT recommends capacity building of management teams at all levels and significant improvement of canal infrastructures. MEW and MAIL staff require training to be able to deliver water efficiently to the farmers’ fields and knowledge of how to make better use of canal resources. The current research resulted in several new approaches including: Developing of farmer organizations to improve O&M practices; Installation of lining in irrigation channels situated in critical reaches; Installation of control and social structures; Implementation of precision land leveling; Improved irrigation practices at the farm level; and Improved delivery of technical information to farmers. Strengthening of Water Users Associations (WUAs) is necessary in terms of improving performance and maintenance of the canal system. AWATT recommends that MEW and MAIL initiate an intensive awareness and training program to increase the farmers’ knowledge of irrigated agriculture and to promote a more judicious use of irrigation water. Practical and vocational ‘in-the-village’ training programs and demonstrations and appropriate and use of audio-visual media may assist in the accomplishment of the broader MEW and MAIL objectives. AWATT also recommends a review of staffing, training, and the provision of necessary resources. Lack of easy access through crossings is a general problem that occurs in most canal-irrigated areas. Future plans should allow for improved access. With such huge losses observed in the system, AWATT recommends the establishment and promotion of an effective operation and maintenance program in joint collaboration with all stakeholders. The distribution of irrigation water among farmers is through a water right per cultivated land. The size of land ownership determines allocation of water rights. If practiced according to Afghanistan Water, Agriculture and Technology Transfer Program 31 AWATT Balkh Watershed Diagnostic Analysis Report schedules, and if outlets are proportional, the amount of water delivered to each farmer would be equitable, to some extent due to non-consideration of canal filling and draining times. Due to physical, management, socio-cultural, political, and financial constraints, equitable water distribution is hard to achieve. As a result, farmers in the tail reaches of the sampled canals often receive the least water and suffer the greatest inequities. Those at the head reaches of the canals receive the most water. Measuring devices installed at all distribution structures would serve the dual purpose of promoting equity and allowing system operators to understand events occurring throughout the system. Though such a solution will not fully serve system operators’ needs, cost is minimal and maintenance simple. Depth markings painted on all permanent structures showing the percentage of full flow in the canal is also recommend to raise awareness and allow farmers to see and easily understand whether the water level at their outlet is at a par with those upstream. Making disparities obvious in this way will lead to improved levels of equity. Significant variations exist in outlet discharges compared to percentages of water and are higher in the downstream reaches of the canal. A detailed hydraulic performance assessment of the canals would ensure equitability of the system. Further recommendations include the promotion of more judicious and improved management of water supply in the canals through capacity building initiatives for all stakeholders. Upstream users should be encouraged to reserve some water resources for use by downstream users. Farmers have reported water shortages in all the sampled irrigation systems, especially in the tail reaches of the canals, suggesting a need to increase the supply of water to the systems. Fluctuations in water supply are apparent due to variations in yearly precipitation and rainfall. Climate change may also contribute to more fluctuations in water availability in the river systems in the future. Construction of a water reservoir to conserve flood water and provide a sustainable water supply to the Balkh River Canal system should therefore be explored for use during water shortage periods. AWATT recommends that online and farm storage systems be assessed in line with water availability and use. A feasibility study into the construction of a water reservoir in Cheshma-e-Shafa to conserve floodwater and overcome water shortages in the system is also recommended. Water shortages could also be tackled and agricultural productivity enhanced through the conjunctive use of surface and ground water, provided that it does not harm water availability in the canals or result in ground water depletion. It is also recommended that springs be recharged regularly. This study shows that water losses in the upstream Mirzae Canal area are between 10 and 12 percent. To prevent water losses AWATT recommends training of farmers, to ensure a better understanding of canal and on-farm water management and crop water requirements, and the introduction of water saving technologies and practices such as: Drip irrigation systems; Ensuring minimum or zero tillage; Land leveling; Afghanistan Water, Agriculture and Technology Transfer Program 32 AWATT Balkh Watershed Diagnostic Analysis Report Plastic layering of the ditches approximately half a meter down; Clearing of weeds along the water flow; Adjusting selection of crops to meet water availability; and Construction of concrete structures on ditches to prevent physical water losses. In order to increase water productivity, managers and farmers need to understand water requirements in different growth stages of each crop and to make use of the technical advice of the MAIL Extension Service relating to the irrigation requirements of each crop. AWATT recommends comprehensive quality and quantity assessments of ground water in the Balkh River Basin. Afghanistan Water, Agriculture and Technology Transfer Program 33 AWATT Balkh Watershed Diagnostic Analysis Report SECTION II: CROP WATER DEMAND AND IRRIGATION SUPPLY Muhammad Jamal Khan and Abdul Hakeem Khan INTRODUCTION Agriculture in Afghanistan, besides providing food and fiber, employs around 47 percent of the country’s labor force. The economy of the country depends heavily on the agriculture sector development. Irrigated agriculture plays an important role and more than 70 percent of agricultural production comes from irrigated areas due to the arid and semi-arid climatic conditions that prevail in the country. To cater to the food and fiber demand of an everincreasing population, there is a need for judicious use of Afghanistan’s scarce water resources. The management of AWATT project is working on the development of replicable agricultural production models to increase overall crop productivity in the target areas, with initiatives also aimed at improving farm incomes and reducing poverty. In order to promote a more judicious use of irrigation water, farmers need to know when to irrigate. They also need to know how much water to apply per irrigation. This study includes an assessment and discussion of average potential evapo-transpiration, rainfall, crops, and irrigation water requirements of major crops grown, as well as irrigation water supply to the three sampled canals in Mazar-e-Sharif. POTENTIAL EVAPO-TRANSPIRATION AND PRECIPITATION Figure 3.1 shows average monthly potential evapo-transpiration (ETo) and precipitation (ppt) levels. These figures show that highest monthly precipitation, approximately 40 mm, occurs in March, with approximately 33 mm in April and February. In general, precipitation received in the area from June to October is negligible, at less than 5 mm. However, the highest monthly potential occurs during July, followed by August and June. It is obvious that agricultural production depends heavily on availability of irrigation water in the area. It is also clear that agriculture production without irrigation has very little potential for development due to low annual rainfall. Afghanistan Water, Agriculture and Technology Transfer Program 34 AWATT Balkh Watershed Diagnostic Analysis Report Figure 2.1: Monthly Potential Evapo-Transpiration (ETo) and Precipitation (PPt) in Mazar-eSharif CROP EVAPO-TRANSPIRATION Multiplication of crop coefficients by potential ETo results in the calculation of evapotranspiration (ETo) of crops grown in Mazar-e-Sharif. Figure 3.2 shows that the maximum and minimum daily crop ETo for major crops grown in Mazar-e-Sharif varies from less than 1 mm/day to 9.5 mm/day. During the summer months, because of high temperatures and low rainfall, daily crop ETo is relatively high. In summer season, the maximum ETo of crops grown stood at approximately 9 mm/day. The crop water requirements of wheat and barley are relatively low when compared to other crops. In general, water requirements for average crops throughout the year ranged from 2-5 mm/day. Afghanistan Water, Agriculture and Technology Transfer Program 35 AWATT Balkh Watershed Diagnostic Analysis Report Figure 2.2: Daily Minimum, Maximum and Average Crop Evapo-Transpiration (ETo) of Major Crops in Mazar-e-Sharif DEPTH OF WATER APPLICATION This study estimates irrigation water requirements of all major crops grown in Mazar-e-Sharif based on 10-day irrigation intervals and an assumed on-farm application efficiency of 70 percent (Figure 3.3). The depth of water application ranged from 10 mm to 135 mm, with an overall average of approximately 70 mm. Afghanistan Water, Agriculture and Technology Transfer Program 36 AWATT Balkh Watershed Diagnostic Analysis Report Figure 2.3: Estimated Depth of Water Application NET SEASONAL IRRIGATION REQUIREMENTS OF CROPS Estimates of the seasonal irrigation requirements of major crops grown in the area assume an overall irrigation system efficiency of 50 percent. Figure 3.4 shows that maximum seasonal irrigation requirements for alfalfa, apple, and apricot are around 2,200 mm. Minimum seasonal irrigation is required for wheat and barley, and average gross seasonal irrigation requirements for vegetable and melon crops grown in the area ranged from 1,000 to 1,200 mm. Afghanistan Water, Agriculture and Technology Transfer Program 37 AWATT Balkh Watershed Diagnostic Analysis Report Figure 2.4: Seasonal Irrigation Requirements of Major Crops in Mazar-e-Sharif POTENTIAL EVAPO-TRANSPIRATION AND WATER ALLOWANCE In Afghanistan, the major government canals operate based on a water allowance set at one liter per second per hectare (L/s/ha). This study estimates potential evapo-transpiration (ETo) based on long-term climatic data and the corresponding water allowance, with an assumed overall irrigation system efficiency of 50 percent and on-farm application efficiency of 70 percent. Conveyance efficiency is also a factor. Figure 3.5 shows that potential ETo reaches nine mm/day with a corresponding water allowance of around two L/s/ha with an assumed irrigation system efficiency of 50 percent. The water allowance observed in the Siagard Canal service area ranged from 0.16 to 0.20 L/s/ha, suggesting that only a small percentage, up to 20 percent, of the area was cultivated in the summer months. In winter, a relatively larger area, approximately 44.7 percent, was cultivated due to the low water demands of wheat and barley crops typically grown in the area during the season. Water allowances for crops grown in Mazar-e-Sharif were determined from daily gross irrigation requirements per unit area assuming overall irrigation system efficiency of 50 percent, conveyance efficiency of 72 percent and on-farm application efficiency of 70 percent. Water allowances of various crops ranged from 0.232 to 2.084 L/s/ha, with an overall average of 0.967 L/s/ha (Figure 3.5). This study concludes that water supply is adequate for crops grown in the area if average irrigation water supply is 1.0 L/s/ha. However, the maximum water allowance for most of the crops grown in the summer months was approximately 1.7 to 2.1 L/s/ha during peak water demand from June through August (Figure 3.6). With average water allowances estimated for the major canals’ command areas found to be 1.0 L/s/ha, this figure appears reasonable. Afghanistan Water, Agriculture and Technology Transfer Program 38 AWATT Balkh Watershed Diagnostic Analysis Report Figure 2.5: Potential Evapo-Transpiration and Related Water Allowance Figure 2.6: Water Allowance of Major Crops Afghanistan Water, Agriculture and Technology Transfer Program 39 AWATT Balkh Watershed Diagnostic Analysis Report CROP WATER DEMAND AND SUPPLY This study uses existing cropping patterns observed during the DA data collection process in June 2009, within the service area of the sampled canals, to calculate crop water demand. Crop water requirements (ETc) were determined by multiplying reference crop evapo-transpiration (ETo) by crop coefficients. Subtracting effective precipitation (Pe) from the ETc calculates net seasonal requirements. Dividing the net irrigation requirement by an overall irrigation system efficiency of 50 percent provides an estimate of gross irrigation requirements. The study observed water level records of the Balkh River and the head-ends of the sampled canals to estimate average water supplies. Discharge from the Nahr-e Shahi Canal, supplied through a gated headwork from the Balkh River, recorded 10.16 m3/s. From Nahr-e Shahi, Siagard Canal is the first branch, which has an official water share of 21.11 percent. Discharge from the canal measured 2.14 m3/s in June 2009. Plate 2.1: The Nahr-e Shahi Canal Headwork on the Balkh River At the time of this study, downstream from the Siagard Canal headwork, work on the Balkh Canal offtake was in progress and due for completion by the end of 2009. Throughout June 2009, the Balkh Canal received water from the Balkh River downstream of the Nahr-e-Shahi Headwork. Farmers in the area were facing severe water shortages in the system and discharge measured was significantly below their water allocation. Plate 2.2: Construction of the Balkh Canal Offtake From Siagard Canal Afghanistan Water, Agriculture and Technology Transfer Program 40 AWATT Balkh Watershed Diagnostic Analysis Report Figures 3.7 to 3.9 show crop demands and water supplies of the Siagard, Mirzae, and Balkh canals respectively. Figure 3.7 shows that farmers at Siagard Canal received a greater water supply than their allocation. At present, cropping patterns and crop water demand in the Siagard Canal’s service area range from 74 to 1995 L/s with an overall average of 475 L/s (Figure 3.7). Irrigation water supplies for existing cropping patterns range from 1130 to 1973 L/s with an overall average of 1444 L/s. On completion of the Balkh Canal offtake, AWATT expects that water availability will decrease because of the diversion of part of the supply to the Balkh Canal in line with water rights in the system. Water supplies to the Balkh Canal are also likely to increase after completion of the Balkh Canal offtake and related conveyance system (Figure 3.9). On completion of the Balkh Canal offtake, the estimated average supply of the Siagard Canal is 967 L/s. With peak water demands observed in May and June, water supplies may not be sufficient for cultivation of all cultivable areas. In-line or on-line water storage may be possible during periods of low water demand and the concept should to be explored further. Figure 3.8 shows crop water demand and irrigation water supplies at the Mirzae. Measurements recorded during this DA show that water supplies in this canal were greater than those recorded at the Siagard and Balkh canals. A relatively high percentage (13 percent) of vegetable crops were grown, indicating better irrigation water supplies compared to the Siagard and Balkh canals, where vegetables were grown on less than one percent of the area. Farmers in the Balkh Canal area faced severe shortages in irrigation water supply, with crop demand ranging from 49 to 1571 L/s with an overall average of 522 L/s (Figure 3.9). Irrigation water supplies varied from 252 to 437 L/s with an overall average of 321 L/s, two folds short of crop water demand. Irrigation water supplies are likely to improve with the completion of the new offtake from the Siagard Canal, scheduled for the end of 2009. Severe water shortages exist in all the sampled canals irrigation service areas. Water shortages have resulted in farmers cultivating only a small percentage of their cultivable land. There is a clear need for conservation and better management of water resources in the area. AWATT also recommends capacity-building initiatives for all stakeholders. Implementation of improved water management practices such as raised beds, better flow control structures, and land leveling is a positive way to promote water conservation in the area.

The economy depends heavily on agriculture sector development, which needs to expand and become more efficient to be able to cope with the future food and fiber demands of an ever-increasing population. Agricultural production is a highly complex process involving the interaction of a large number of disciplines from biological, physical and social sciences. Having a sound policy framework, including effective price policies for agricultural input and output is the key to developing a successful and vigorous natural agricultural sector. Despite the lack of perfect policy frameworks currently in place, actual productivity of the farmers’ fields can be determined through three important sets of inputs: Availability of water; Improved forms of tested production technologies; and Timely provision of quality input at appropriate prices. Reduced productivity is a result of deficiencies in these inputs and the inability of farmers to capitalize on the full potential of their land. This DA seeks to investigate the severity of the problem and to identify potentially feasible crops and land and water management interventions at the farm level that will help improve current productivity levels. One of the objectives of this analysis was to identify the strengths and weaknesses of the existing agriculture system practiced in Mazar-e-Sharif. In the sampled canals command areas, the cropping patterns and yields of major crops during summer and winter seasons were determined from the data collected in the field through a performa questionnaire developed as part of the study. A total of 59 farmers responded to questions relating to the following issues: Landholdings; Cropping patterns; Crop yields; and Irrigation numbers and intervals in the sampled canals command areas in Balkh River Basin. Afghanistan Water, Agriculture and Technology Transfer Program 44 AWATT Balkh Watershed Diagnostic Analysis Report This section of the report presents a summary of findings relating to agricultural issues. LANDHOLDING AND TENANCY STATUS The average landholding per household in the sampled canals service area ranged from 3.76 to 15.66 ha with an overall average of 9.36 ha (Table 3.1). Observation of the data across canals (Figure 3.1) suggested that the majority of farmers are owners and results show almost no producer rents in the Balkh Canal. Sixty-three percent of farmers in the service areas of the sampled canals were landowners, while 19 percent were tenants and a further 19 percent owner/tenants (Figure 3.2). Landholdings per household are small, with overall average landholding per household standing at two to three times greater than the cultivated area. Measurements recorded during this DA show land ownership in the majority of land situated at the tail reaches of the Siagard and Mirzae. In the Balkh area, land ownership is greatest at the head reaches of the canal. The survey revealed no cases of land ownership at the tail reaches of the Balkh Canal. Table 3.1: Landholding by Location Along the Canals Location Canal Mirzae Siagard Head Balkh Mirzae Siagard Middle Balkh Mirzae Siagard Tail Balkh Owned Area 60 164 202 52 50 65 133 860 0 Rented Area 38 119 191 32 40 55 75 183 70 Figure 3.1: Tenancy Status of the Farmers at all Canal Service Areas Afghanistan Water, Agriculture and Technology Transfer Program 45 AWATT Balkh Watershed Diagnostic Analysis Report Figure 3.2: Tenancy Status of Farmers at Siagard Canal Service Area Table 3.2: Average Land Holdings and Cultivated Area During Summer And Winter Seasons Per Household (2008-2009) Sample Canal 1 2 3 Siagard Balkh Mirzae Overall average Sample size 16 27 16 Total landholding per household (ha) 15.66 8.67 3.76 9.36 Cultivated Area per household (ha) 1.83 7.25 2.40 4.61 0.74 1.75 1.66 4.54 In general, the DA found that only 20 percent of the total cultivable land was cultivated in the summer months, compared to 48 percent in the winter months, due in part to increased rainfall and lower crop water demand during the winter season. FALLOW LAND Because of water shortages in the system and low rainfall, most land is left fallow, with cultivated land per household during the summer and winter months in the command areas of the three sampled canals ranging from 0.74 to 7.25 ha. Findings from this study show that farmers, on average, cultivate only around 20 percent of the land area in the summer months due to scarcity of water and relatively high irrigation requirements. During the winter season up to three times more land is cultivated. Afghanistan Water, Agriculture and Technology Transfer Program 46 AWATT Balkh Watershed Diagnostic Analysis Report Cropping intensity during the summer season ranged from 21.1 to 27.8 percent, compared to 44.7 to 53.1 percent in the winter season (Figure 3.3). Percentages of fallow land in the service areas of the three sampled canals during the summer and winter seasons show that significant portions of landholdings are left fallow due to insufficient supplies of irrigation water. Fallow land during summer and winter seasons ranged from 72.7 to 87.9 percent and 46.9 to 55.3 percent respectively. Fallow land accounted for an average of around 80 percent of land in the summer season and 52 percent in the winter season, due mainly to shortages of irrigation water supply and low rainfall in the area. Figure 3.3: Percentage of Fallow Land in the Three Sampled Canals CROPPING PATTERNS Data analysis shows wheat is the dominant crop grown during the winter season, accounting for 33.3 to 39.3 percent of the land. Barley accounts for 4.4 to 10.8 percent of the service area of the three sampled canals (Figures 3.4, 3.6 and 3.8). In the spring season cotton is the dominant crop, accounting for 6.9 to 17.6 percent of the land, followed by melon, watermelon, and vegetables grown on areas representing 1.5 to 10.9 percent, 2.4 to 4.6 percent, and 0.1 to 13.6 percent respectively (Figures 3.5, 3.7 and 3.9). CROPPING CALENDAR Wheat and barley are the major crops grown between mid-October and mid-November. Harvesting of these crops typically takes place in June (Table 3.3). In the spring, alfalfa, cotton, melon, watermelon, eggplant, okra, and cucumber are the predominant crops in the upstream reaches of the service areas of the canals. In summer, maize, cumin, and sesame account for a small percentage of the cultivable land area.

In general, average yields of wheat, barley, cotton, and watermelon were higher at the middle reaches of the sampled canals than at the head and tail reaches, possibly because of over-irrigation at the head reaches and under-irrigation at the tail reaches where there is a relatively lower availability of irrigation water. Yields of melon were significantly better at the middle and tail reaches of the sampled canals due to the crop’s low water demand.

This study recorded significant variations of between one and nine fold between the minimum and maximum yields of the sampled crops. In general, average production at the tail reaches of the canals was lower than that at the head and middle reaches. The DA concludes that better management of water resources will result in enhanced wheat production in all reaches of the canals.

The least number of farmers applying improved seeds are located in the tail reaches of the Siagard canal. LIVESTOCK The livestock subsector complements crop production by contributing cash income (sheep and goats), improving family nutrition (dairy cow), soil fertility, and farm power in soil preparation (bullocks). Figure 3.10 show that sheep and goats are the most common livestock, followed by cows and bullocks. This study revealed an average of 14.1 sheep and 4.2 goats per household in the service areas of the sampled canals. Each household surveyed also had an average of one cow, one bullock, and one donkey. Due to drought and food shortages, especially during the winter months, the amount of livestock has declined. There is a great potential for livestock improvement through breeding, improved feed and effective management.

Table 4.6 shows that at least 50 percent of farmers across the canals have no education and that just 5 percent have 11 or more years of education. Results showed that there are no significant differences in education levels between the various canals and sampled locations. Table 3.6: Years of Education Among Surveyed Farmers Years of Education Amongst Farmers Canal 0 years 1-5 years 6-10 years 11 + years Mirzae Siagard Balkh 68% 72% 48% 0% 6% 13% 16% 22% 35% 16% 0% 4% AGE VARIABLES The main aim of the age variable in this preliminary analysis was to identify the correlation between education and age. Almost all the farmers in the age range of 21-40 years have no education. Results show no significant differences between the various sampled canals and locations (see Figure 3.15 and 3.16). Figure 3.15: Education Correlation Across All Sampled Canals Afghanistan Water, Agriculture and Technology Transfer Program 56 AWATT Balkh Watershed Diagnostic Analysis Report Figure 3.16: Education Correlation by Age and Location MAIL EXTENSION SERVICE The MAIL Extension Service in Mazar-e-Sharif has a mandate to extend the technology developed at research institutes to farmers in the region, particularly those located in the Balkh Canal service area. The Agricultural Research Institute of Afghanistan (ARIA) is responsible for conducting all types of research relating to agriculture in the country. The DA survey revealed that contact between farmers and MAIL Extension workers is negligible. Most farmers mentioned that they gather information from progressive farmers in their area and private dealers. There is a great need to mobilize MAIL Extension staff so that farmers in the area can get access to the full benefits of modern technology developed by research staff. Findings from the DA show that farmers connected with the MAIL Extension Service via visits to and from agents produce the most profitable crop and are located on the most irrigated land. The exception is for farmers producing onion, who visit the MAIL Extension agents but do not receive visits from them (Figure 3.17). Findings also show that farmers across the sampled locations and canals visited by MAIL Extension agents are likely to clean the canals less frequently compared to those not visited by the department (Figure 3.18). Afghanistan Water, Agriculture and Technology Transfer Program 57 AWATT Balkh Watershed Diagnostic Analysis Report Figure 3.17: Percentage of Farmers by Crop Who Are Visited and Receive Visits from MAIL Extension Agents Figure 3.18: Comparison between MAIL Extension Agent Visits and Canal Cleaning Afghanistan Water, Agriculture and Technology Transfer Program 58 AWATT Balkh Watershed Diagnostic Analysis Report FARMER INVOLVEMENT The survey shows that the majority of farmers in the sample who participated in MAIL Extension activities during past year were located at the Mirzae Canal. MAIL Extension activities were least popular with farmers at the Balkh Canal. Figure 3.19 – Farmer Involvement in Extension Activities CONCLUSIONS AND RECOMMENDATIONS Results of this DA suggest the need for improvements to agricultural productivity and market access: Improved water availability; Increased availability of high quality seeds, fertilizers and farm machinery; and Capacity building, training, and increased market access. IMPROVED WATER AVAILABILITY Water availability must be enhanced and training arranged for better on-farm water management. Water saving technologies such as drop irrigation, minimum or zero tillage, land levelling and plastic mulching for conservation of moisture should be promoted. In order to increase productivity farmers also need to understand irrigation requirements in the growth stages of each crop and make use of the technical advice provided. Afghanistan Water, Agriculture and Technology Transfer Program 59 AWATT Balkh Watershed Diagnostic Analysis Report INCREASED AVAILABILITY OF HIGH QUALITY SEEDS, FERTILIZERS AND FARM MACHINERY Disease and insect infestation remains a great problem, with the majoirty of farmers complaining about infestation by aphids, cutworms and root rots in alfalfa, cucumber, okra and other crops. Farmers also complain about the low quality of plant protection chemicals and phosphorus-based fertilizers. It can be concluded the MAIL needs to play a more prominent role in providing adequate facilities and resources to assist farmers with plant protection issues, and to encourage farmers to participate actively in the judicious use of high quality insecticides and fertilizers. Extension workers from provincial agricultural departments should visit farms more frequently to inform farmers of the availability of better quality of fertilizers, seeds, pesticides, and to advise on other technical issues including quality control and food security. Strengthening of the MAIL Extension Service will help agents to transfer new technologies more effectively to farmers. CAPACITY BUILDING, TRAINING AND GREATER MARKET ACCESS The majority of farmers in the service areas of the sampled canals have not received any formal training. A small percentage of farmers have received training in plant protection and production through the Food and Agricultural Organization of the United Nations (FAO) and other nongovernmental organizations. Most farmers surveyed showed interest in agricultural training, particularly in relation to plant protection, production technologies, and water management. Survey results also indicated the need for more judicious use of fertilizers, pesticides and insecticides and improvements in agronomic practices and productivity in relation to seed rates, water application, and cultivation methods. Low soil fertility in some areas combined with high disease and insect infestation rates remain a cause for concern. Farmers also complained about low yields and the quality of plant protection and fertilizer chemicals available, particularly the use of phosphorus. Results of the survey indicate the prohibitive cost or non-availability of quality seeds, insecticides, fertilizers, and farm machinery, as well as perceived flaws in the MAIL Extension Service. Results of the DA survey also indicated a desire for greater and improved access to transportation and market facilities, veterinary services and bank loans for small farmers, as well as the strengthening of farmer organizations and the development of demonstration plots. In order to increase agricultural production, productivity, and income, AWATT recommends that farmers receive technical training not limited to agricultural issues. Farmers should acquire the knowledge to understand concepts of cost and return analyses and net profit and loss. An effective marketing system needs to be put in place to allow farmers to gain sufficient income from their land through the purchase of input and sale of products. Quality inputs must be made available to the market and farmers should have access to input through credit and purchase of their products. Access to storage and cold chain facilities may also enhance market linkages and infrastructure.
