This study examines irrigation water management activities in Metti-Walga irrigationrnscheme and effects of this irrigation on crop production, income generation andrnemployment cr eation with existing water control. To serve this objective, householdrnsurvey, FGDs, interview and field observation were used to colJect data at group andrnindividual levels. The questionnaires were administered and filed by using 10calJyrnrecruited and trained enumerators. The analysis was undertaken using simplernstatistical methods. 105 respondents were selected by lottery method from the totalrnpopulation of 740 irrigators.rnThe findings of this study highlight the negative effects of irrigation on cultiva ted landrnand agricultural productions. Mismanagement of irrigation water resulted in rise of thernwater table, which ca uses water logging. About 20 hectares of the cultivated land atrnlower-lying and flat areas are converted to water logged and the production of irrigatedrncrops declined. However, the irrigation scheme enables farmers to generate morernincome and able to create employment in the scheme. The Price and demand forrnirrigated crops increase due to facilities improved fOJ- m arketing agriculturalrnproductions. But sustainability of the scheme is in a serious problem.rnThe study reveals that irrigation use activities such as control structure, waterrnmanagement activities and organizational structures are inadequate. Conveyancernsystems are inefficient because of water loss through ca nal seepage, percolation andrnleakage. Water use activities s uch as water alJocation, distribution and field applicationrnare inappropliate.rnOrganizational structures that are responsible for managing the physical structures andrnwater use activities l ack coordination and integration. This resulted in inefficiency ofrnthe irrigation system .rnFarmers were organiz ed in the form of Irrigation Groups and Water Users Groups forrnactivities ofinigation management but lack institutional arrangement and inadequaterntl-aining of users made organizational control activities. Woreda Agricultural and RuralrnDevelopment Office has shortage of skilled manpower and budget to train and assistrnthe farmers in operation and maintenance of the control structures. Hence, lack ofrnawareness, skl1led m anpower and coordination to manage irrigation system m ake thernconveyance system and field application inefficient. These poor irrigation waterrnmanagement activities causes wastage of water that resulted in shortage of inigationrnwater in the scheme and conversion of cultivated land to water logging.
