In north eastern part oj Ethiopia, drought induced Jood insecurity has been a long-lastingrnproblem. In this thesis, an attempt made to identify householdJood security status and itsrndeterminants in one oj drought prone area- Gubalaflo Woreda. Moreover, the linkagesrnbetween Small Scale Irrigation and household Jood security in provision oJJood energyrnassessed. A multi- stage stratified sampling procedure was used to select 115 samplernhouseholds Jrom both irrigation users and non-users living within the targeted kebeles. Arncombination oj quantitative analysis like descriptive statistics, Household Food BalancernModel, binary logit model and qualitative study were used to reach at reliable results byrnusing data gathered Fom both primm)' and secondary sources. The survey resultrnrevealed that 29 % oj sample households were Jood insecure and 71 % Jood secure.rnThere is huge gap in Jood calorie availability ranging Jrom 788- 8405Kca in the studyrnarea. Food insecure households wereJound to have an average oJ24%Jood gap in termsrnoj dietary energy, which is needed to fitlfill the national minimum requirements. Thernaverage per capita calorie supply Jor irrigation users was Jound substantially increasedrnby 889 Kcal, which is about 42 % percent oj the minimum requirement oj Jood caloriernrequires by an individual. The use oj SSI was Jound significantly related to householdrnJood security situation in provision oj household dietmy energy and taking a lion share inrnthe proportion oj study areas major consumable Fom food crops production. The logitrnmodel revealed that household size, educational status oj household head, number ojrnfarm oxen, cultivated land size, engagement in nonj'arming, access to irrigation andrncredit service were Jound significant determinants. Correspondingly, the study disclosedrnthat the long distance between irrigated land to Jarmers residence, lack oj cleaning andrnmaintenance oj scheme, Jree grazing, poor irrigation methods and crop selection werernthe major constraints in the irrigation Jarm. SSI is one oj the viable solutions tornhousehold Jood supplement and hence promoting oj smallholders to produce directlyrnconsumable Jood grains is advantageous. It is important to address those Jood securityrndeterminants and Jarmers' views in planning and executing oj development policies andrnprograms by all stakeholders to tackle the problem oj household Jood insecurity in thernstudy area.
