The population studied comprises the. ~gricultur~lhOl~seno.'ds ofa co~uruty inrnDamota district which is found in the North Omo administrative region. It was stratifiedrnby using the agro-ecological factor as the stratifying variable into three strata. Thus, thernthree strata arrived at in the process were the "Dega", "Kolla", and "Woyna Dega" agroecologicalrnzones in the research area.rnIn the case where the study variables of interest are greater than one in a stratifiedrnsample survey, the usual optimum (Neyman) allocation method cannot be applied directlyrnsince what is best for one study variable may not necessarily be best for the other. Thus,rnother alternative techruques developed to go about this problem have been compared.rnThese include the compromise, chatterjee as well as proportional allocation. Other methodsrnwhich involve non-linear programmingtechruques were also reviewed.rnThe data on the study variables which were believed to be indicative of the foodrnsupply system of the area were collected These included the family size, acreage, production,rnexpenditure, reserves and purchases of the households. This was done through interviewsrncarried out by going to the sampled households. Prior to the conduct of the final survey,rnhowever, a pilot survey was undertaken which covered fifty households from each stratum.rnThis was done in order to obtain the necessary information to estimate the stratumrnvariances which were required for sample allocation purposes. The sample sizern2rndetermination was also done scientifically by similarly using the data from the pilot surveyrnas well as the approved budget of the survey and additional cost estimates.rnIn addition to the above, anthropometric measures of children under five years of agernwere collected for the purpose of studying the nutritional status of the populationrnrnconsidered
