4.1 Determinants of Household Food Security
The following section discusses logistics regression analysis to assess the determinants of household food security from the perspective of a sustainable livelihood security framework and in relation to the impact of urban eviction of peri-urban farmers. This analysis aimed to identify the key factors that influence food security, represented by the dichotomous variable "Food Security Level", using variables of sustainable livelihood security indicators.
Statistical tests such as the Mann-Whitney U test used for this study show that a significant difference in food security levels between evicted and non-evicted households. Specifically, the U value of 7519.000, combined with a Wilcoxon W value of 32495.000, shows that there is a significant difference between the two groups. The Z-value of -13.703 and the p-value of .000 (which is less than the commonly used alpha level of 0.05) indicate that the observed difference in food security between evicted and non-evicted households is statistically significant. The effect size was 0.6489, which implies that the effect of eviction on household food security is very high. We have strong evidence to reject the null hypothesis, and therefore, the null hypothesis is rejected. The evicted and non-evicted households have different household food security levels.
From this perspective, the classification tests achieve an overall classification accuracy of 87.9%, with 90.8% accuracy in predicting Non-Food-Secured cases and 84.1% accuracy in predicting Food-Secured cases. This marked improvement highlights the efficacy of predictor variables in distinguishing between food-secure and food-insecure households.
Similarly, the inclusion of predictor variables significantly enhances the performance of the model, as indicated by the Omnibus Model Coefficient Tests (Chi-square = 358.100, df = 17, p < .001). The Hosmer and Lemeshow test (Chi-square = 10.724, df = 8, p = .218) also suggests that the model fits the data well, as the p value is greater than .05, indicating that there are no significant differences between the observed and predicted outcomes. The − 2 Log likelihood value decreases to 253.137, suggesting a better fit. The Cox & Snell R square (.552) and Nagelkerke R square (.740) values indicate that the model explains a substantial portion of the variance in the food security status.
The study results shown in Table 1 below summarises the key results from the logistic regression analysis on the impacts of independent variables on household food security in the perspective of sustainable livelihood security framework and urbansaztion-induced eviction of the peri-urban farmers.

In Table 1 above, the logistic regression analysis identifies several key predictors of food security among households. In particular, eviction status, social security, land security, ICT security, and SLSI scores emerge as significant factors. These findings underscore the multifaceted nature of food security, influenced by socioeconomic, educational, and infrastructural dimensions. The logistic regression output provides insights into the significance and impact of each predictor variable on food security as follows:
-
Eviction status: Households that have been evicted are significantly less likely to be food secure (B = -2.717, p < .001, Exp (B) = .066). Evicted households are significantly less likely to have food security, with an odds ratio of 0.066. This means that eviction drastically reduces the likelihood of food security, highlighting the vulnerability of evicted households and the need for targeted interventions to support those evicted households (Sharafkhani et al., 2011). Eviction is a significant negative factor that requires policies to prevent eviction and support affected households.
-
Wife Education Level: Marginally significant (p = .052), with higher education levels associated with increased food security (Exp (B) = 2.687). Households where the wife has a higher education level are approximately 2.687 times more likely to have food secure compared to households where the wife has a lower education level. This highlights the critical role of women's education in improving household food security, as supported by studies that emphasise the positive impact of women's education on food security (Mutisya et al., 2016; Obayelu, 2012). The role of women education is crucial for improving food security, highlighting the need for educational programmes that target women.
-
Social capital Security: Significant (p = .013), with higher social capital security associated with increased food security (Exp (B) = 2.530). Households with higher social capital security are about 2.53 times more likely to be food secure. This significant effect underscores the importance of social protection programmes in improving food security, corroborated by findings in the literature (Hidrobo et al., 2018; Devereux, 2016). Social security is vital to improving food security, indicating the effectiveness of social protection measures.
-
Land Tenure Security: Significant (p = .010), with greater land tenure security associated with increased food security (Exp (B) = 2.555). Households with better land tenure security are approximately 2.55 times more likely to achieve food security. Secure tenure and access to land resources play a pivotal role in ensuring food production and availability (Maharjan & Joshi, 2011). Land security is essential for food production and stability, supporting land tenure policies.
-
Human capital Security (B = 0.179, Sig. =0.433, Exp (B) = 1.197) : Households with higher human security are about 1.197 times more likely to be food secure. Human security encompasses aspects such as health, education, and employment, which are essential for maintaining stable livelihoods and food security (Manap et al., 2019). Human security is important for general well-being and food security, highlighting the need for comprehensive human development programmes.
Specifically, the logistic regression coefficient for the status of eviction (Eviction Category (1)) is -2.717 with a standard error of 0.66. The Wald chi-square test yields a value of 18.790, which is highly significant (p < .001). The odds ratio (Exp (B)) is 0.066, with a 95% confidence interval ranging from 0.019 to 0.226.
The negative coefficient (-2.717) indicates an inverse relationship between eviction status and food security. Specifically, households that have experienced eviction are significantly less likely to be food secure compared to those that have not been evicted.
The odds ratio (0.066) suggests that the odds of being food secure for evicted households are 93.4% lower than for non-evicted households. In other words, evicted households have approximately 1/15th the odds of being food secure compared to non-evicted households.
The p-value (< .001) indicates that the relationship between eviction status and food security is highly significant, meaning the likelihood of this relationship occurring due to random chance is extremely low. This strong statistical significance underscores the robustness of the status of eviction as a predictor of food security.
The 95% confidence interval for the odds ratio (0.019 to 0.226) does not include 1, further confirming the significant impact of eviction on food security. The narrow range of the confidence interval enhances the reliability of the estimated odds ratio.
These findings underscore the importance of education, social, land, and human security in determining food security. Interestingly, eviction significantly reduces the odds of securing food, highlighting the vulnerability of evicted households.
The study result in Table 1 specified that the logistic regression model identified several predictors with significant odds ratios (Exp (B)), indicating their influence on the likelihood of achieving food security. The analysis confirms that the null hypothesis, eviction has no significant negative impact on the food security of evicted households, is rejected. There is strong evidence to reject the null hypothesis.
The findings of this study highlight the significant negative impact of urbanization-induced eviction on the food security of peri-urban farming households in Addis Ababa. The stark contrast in food security levels between evicted and non-evicted households underscores the critical role that access to agricultural land plays in maintaining food security in these communities. The dramatic decline in food security indicators following eviction reflects the multidimensional nature of the challenges faced by displaced households. Not only do they lose their primary means of food production, but they also experience disruptions to their social networks, economic stability, and overall livelihood strategies. This aligns with previous research highlighting the complex impacts of displacement on food security and well-being (FAO, 2017; Maxwell & Wiebe, 1999).
The identification of key factors influencing food security, such as education levels, social capital, and land security, provides important insights for policy interventions. These findings suggest that comprehensive approaches addressing multiple dimensions of household vulnerability are necessary to improve food security outcomes for displaced communities.
4.2 Level of households’ food security before and after eviction
Food security is a critical aspect of human well-being, which includes the availability, accessibility, and use of nutritious food that supports a healthy and active lifestyle. This section examines the impact of land expropriation on household food security in the Lemmi Kura subcity, Addis Ababa. The analysis is based on data collected from 223 displaced households, assessing their food security status before and after eviction.
The research employed a survey methodology, focussing on key indicators of food security, which include adequate meal quality, healthiness and variety of food, frequency of meals, food production, and affordability. The responses of the households were classified into five levels of food security: 1) severely food insecure, 2) food insecure, 3) Fairly food secure, 4) Good food secure, and 5) Fully food secure. The data collected was then analysed to determine the change in food security levels before and after eviction.
The findings of the research shown on Table 2 clearly illustrate a dramatic decline in food security among displaced households after eviction. Before eviction, a substantial majority (80.27%) of households were food secure, with 66.37% being fully food secure. This changed drastically after eviction, with the mean level of food security falling to 8.07%.

Before eviction, approximately 80.27% of the respondents were at a good or fully food secured level, fulfilling all food security indicators. However, after eviction, about 79.82% of the respondents fell into the category of severely food insecure, not meeting any of the food security indicators.
The substantial decrease in food security after eviction highlights the severe consequences of land expropriation on the livelihoods of households in the Lemmi Kura sub-city. The loss of agricultural land, which was a main source of food production and income, resulted in reduced meal adequacy, reduced variety and healthiness of food, and decreased frequency of meals. These findings align with existing literature that emphasises the adverse effects of displacement on food security (FAO, 2017; Maxwell & Wiebe, 1999).
Similar research indicates that eviction not only disrupted households' ability to produce their own food but also limited their financial capacity to purchase adequate and nutritious food. This research confirms the significant change in food security levels, where nearly 87% of households became food insecure after eviction.
The study underscores the critical impact of land expropriation on household food security in the Lemmi Kura sub city. The displacement led to a drastic decline in food security levels and most households became food insecure. Policymakers must consider the severe implications of such actions on the well-being of affected communities and develop strategies to mitigate these adverse effects. Ensuring access to alternative livelihoods and food sources for displaced households is essential to improve food security and overall well-being.
4.3 Indicators of food security
Urban expansion and the resulting eviction of peri-urban households have profound implications for food security and access to nutritious diets. This section examines the dramatic changes in households' ability to produce and afford sufficient food following displacement. The section interprets the detailed data on evicted household food security in the Lemmi Kura sub-city, Addis Ababa, focusing on various indicators and comparing the “before” and “after eviction” cases. The indicators assessed include the ability to eat enough food throughout the year, the consumption of adequate variety of food, the number of meals per day, the access to healthy and nutritious food, the production of enough food, and the affordability to buy food when its own production is insufficient.
The data provided in Table 3offer a comparative analysis of food security levels before and after eviction.

The above data, shown in Table 3, reveals a severe decline in food security indicators, including the ability to eat enough food throughout the year, access to a variety of adequate foods, and self-sufficiency in food production. Furthermore, the affordability of food when one's own production is insufficient has become a significant challenge for these households. The findings underscore the critical need for policies and interventions that address the food security crisis faced by peri-urban communities displaced by urbanization. The detail analysis for each indicator is summarised as follows:
Household ability to eat enough food throughout the year
The mean score after eviction is 0.1256, indicating a severe decrease in households' ability to eat enough food throughout the year. However, before eviction, the mean score was 0.9327, which means that almost all households were able to eat enough food throughout the year.
Eating the right types of food throughout the year
the mean score after eviction is 0.1166, reflecting a significant reduction in the variety and adequacy of the foods consumed. On the other hand, before eviction, the mean score was 0.8520, showing that households had access to a variety of adequate foods.
Number of meals per day
The mean score after eviction is 0.8789 (88% of three meals per day), indicating that while the number of meals per day remains relatively high, it has still decreased. However, the mean score before the eviction was 1.00, which indicates that the households usually had three meals per day.
Access to sufficient healthy and nutritious food throughout the year
the mean score after eviction is 0.0807, highlighting a drastic reduction in access to healthy and nutritious food. However, before eviction, the mean score was 0.8341, indicating that households had previously considerable access to nutritious foods.
Production of enough food for the family
the mean score after the eviction period is 0.1121, showing a significant drop in the ability of households to produce enough food, while the mean score before the eviction was 0.9013, reflecting that households were largely self-sufficient in food production.
Affordability to Buy Enough Food When Own Production is Insufficient
The mean score after eviction is 0.1076, indicating that households struggle to afford food when their own production is insufficient. However, the mean affordability score before eviction was 0.7758, suggesting that households had the financial means to buy food when needed.
The data clearly demonstrate a stark contrast in the levels of food security before and after eviction. The mean level of total food security dropped from 0.9288 before eviction to 0.3974 after eviction. This sharp decline underscores the adverse impact of land expropriation on the ability of households to secure adequate food.
The most affected indicators are access to enough healthy and nutritious food and the overall ability to produce enough food for the family. These findings align with existing research that points to the detrimental effects of displacement on food security and livelihoods (FAO, 2017; Maxwell & Wiebe, 1999).
The above analysis provides compelling evidence of the significant negative impact of eviction on household food security in the Lemmi Kura sub-city. The decline in all food security indicators after eviction highlights the need for urgent policy interventions to support displaced families. Strategies to improve access to food, enhance food production capacities, and provide financial support are essential to mitigate the adverse effects of land expropriation on food security.
The data in Table 3 show that the loss of agricultural land and assets significantly impacted the food security of displaced households, leading to food insecurity and dependence on market purchases for their food needs.
Historically, the farming communities in Lemmi Kura sub city of Addis Ababa had the autonomy to choose their food and drink, which also allowed them to support others within their community. This self-sufficiency led to a secure food environment. However, the current shift towards purchasing all food items has compromised this food security, putting current food security at risk (P5).
Before evictions, the farming communities of the research area were largely self-reliant, providing mutual assistance even when not all members were food insecure. Post-eviction, they have become dependent on external support, reflecting a significant change in their ability to support themselves (P8).
According to a key informant of this research, several factors contribute to food insecurity in peri-urban areas, such as lack of innovation and subsequent unemployment, loss of agricultural land, loss of assets during evictions, and displacement of livestock due to urbanisation. Reduced agricultural land directly decreases food production capacity, jeopardising food security (P1).
The ownership of agricultural land is crucial to producing a variety of crops that ensure food security. The loss of this land prevents people from guaranteeing their own food supply, thereby endangering their livelihoods (P1). The confiscation of agricultural land has led to a significant loss of livelihood and assets. Without land, individuals cannot raise livestock or grow crops, exacerbating their challenges to economic and food security (P4). Evicted households in the peri-urban areas are currently facing severe food crises. These crises manifest themselves as unstable access to adequate and healthy food, financial difficulties, and other related challenges (P3).
After being displaced from their land, villagers often face unemployment or are forced to work in informal employment. This transition results in a substantial decrease in income and an increase in malnutrition due to reduced food availability (P5). Households that have not been evicted can harvest crops from their land, thus enjoying more reliable food security. In contrast, evicted households face increased food insecurity, lacking the means to produce their own food (P2).
The qualitative insights from focus group discussions and interviews provide a deeper understanding of the lived experiences of evicted households. The loss of self-sufficiency and increased dependence on market purchases for food represent a fundamental shift in livelihood strategies that can have long-lasting impacts on household food security and resilience.
These findings have important implications for urban planning and development policies in rapidly growing cities like Addis Ababa. The current approach to urban expansion, which often prioritizes land conversion for urban uses over the preservation of peri-urban agriculture, may have unintended consequences for urban food systems and the well-being of displaced communities (Adam, 2020).
