Quantitative ethnoecological analysis of uses, management and yield of Z.spina-christi revealed that,it has multipurpose popular socioeconomic roles being preferred by local people of semiarid eastShewa, Ethiopia. Relative abundance and density of the species for 66 plots was 44% and 3respectively. Average fruit yield was 200 kg per year and the price was 30.21 $USD. Fruits weregathered from Z. spina-christi throughout the year including the critical months before harvest ofannuals when food supply runs low. It is rich in carbohydrates, proteins, minerals and fats. Thefruits have been accessible year-round with an overlap of acute food scarcity and years of goodharvest. The present study has shown that Z.spina-christi is naturally available, cheap and locallyaccessible alternative for resolving part of the food shortage problem and for maintainingbiodiversity. The consumption of Z.spina-christi was a necessary part of the strategies adopted bypeople in order to survive in a harsh and unforgiving environment. The potential nutritionalcontribution of the species to the people’s diets remained in the informal production sector.Multipurpose uses of the wood, bark, leaves, roots and fruits the species were not supported bymodern technology having been purely traditional utilization. The potential in household food,healthcare, livestock nutrition were not properly documented and utilized in the study area. Hence,the species is a key candidate for dry land agro forestry and enhancement of agro biodiversity forhuman food and other multiple uses.
