The main objective of this research was to assess the household food security, nutritional KAPrnand WASH practices in Dugda woreda, East Showa zone, Oromia Region, Ethiopia. Bothrnqualitative and quantitative research methods were employed. Data was gathered from bothrnprimary and secondary sources. The survey questions were collected from 147 vegetablernproducers and an equal proportion of non-producers to evaluate the positive impacts ofrnvegetable production on household food security status, nutritional and WASH practices. Thernresult showed that the majority (61.2%) of vegetable producing households were food secure.rnAmong the vegetable non-producers, only 15.6% of the households were food secure. The restrnwere either mildly (42.2%), moderately (25.2%) or severely (7%) food insecure. Fruit andrnvegetable crops generated more income to farmers than did traditional staple crops. About 49%rnof vegetable producing households get a monthly income of ETB 3000 or higher, whereas onlyrn2.7% of vegetable non-producers get ETB 2001- 3000 per month. Less income leads to lessrnpurchasing power. Both vegetable producers (69.2%) and non-producers (76.7%) had goodrnknowledge concerning appropriate household nutritional issues, though additional education onrnnutrition was needed. They understood the importance of feeding complementary foods to theirrnchildren at six months of age in addition to breastfeeding. But they had poor practice andrnknowledge on feeding children with diversified diet. Appropriate nutritional practice was notedrnin 71.6% and 38.9% of vegetable producers and non-producers, respectively. Almost allrnrespondents (86.4%) in both groups supposed that feeding children several times each day wasrndifficult. Caregivers and mothers, thus, fed their children with less frequency and diet diversity.rnAbout 96% and 37% of vegetable producer and non-producer respondents, respectively, usedrnpiped water and appropriate practice on water sanitation was observed in 60.2% and 43.6% ofrnvegetable producer and non-producer respondents, respectively. About 74.8% of vegetablernproducers and 50% of non-producers had good knowledge on critical time to wash hands.rnHowever, there were inappropriate practices in hand washing.
