Technical efficiency of teff farms in Ethiopia: Do neighborhood effects matter? A copula stochastic frontier and spatial Durbin regression.

Teff is essential to most Ethiopians, but its production is hampered by farmers' characteristics and spatially related neighborhood variables. This study analyzes the neighborhood effect on the technical efficiency of teff farms in Ethiopia using panel data from the Ethiopian socioeconomic survey. The spatial Durbin regression models (SDM) and Copula stochastic frontier were used with 858 teff-growing farmers. The mean value of teff's technical efficiency was found to be 53 %, meaning that farmers had a 47 % likelihood of improving teff farm efficiency. The results from the SDM indicate a significant contribution of neighborhood effects for improving technical efficiency in teff farms. Thus, policymakers could explore implementing localized interventions and knowledge-sharing initiatives to disseminate best practices, innovative technologies, and agronomic knowledge within specific spatial clusters. By doing so, they can leverage the observed influence of neighborhood dynamics on teff farm efficiency.

Can farmers' climate change adaptation strategies ensure their food security? Evidence from Ethiopia.

Climate change poses a significant threat to the sustainability of agricultural production among smallholder farm households in Ethiopia. To reduce the adverse effects of climate risks, farm households have sought to adopt different adaptation strategies. This study investigates factors influencing farm households' choice of climate adaptation strategies and associated effects on their food security in Ethiopia using data collected from 516 farm households from three regions. A multivariate probit and propensity score matching models were used to analyze data. Major adaptation strategies adopted by the farm households in the study area are planting drought-tolerant crop varieties (60%), changing the planting dates (53%), growing diversified crops (49%), and diversifying the sources of household income (45%). Results suggest that older farm household heads are more likely to use drought-tolerant crop varieties to reduce climate risks. Farm households with larger farmland size and those with more years of experience in farming are more likely to use drought-tolerant crop varieties and crop diversification strategies. Farm households with larger family size are more likely to use crop and income diversification strategies and change the planting dates against the backdrop of a high risk of climatic shocks. Membership in input supply cooperatives, frequency of contact with extension agents, and access to information on expected rainfall and temperature are positively associated with different adaptation practices adopted by farm households. Farm households who have adopted climate adaptation strategies have higher food security status (by 2.3-2.8%) compared to those who have not. Thus, the farm households' climate adaptation practices have positive food security effects in Ethiopia.

Impact of income diversification on rural household food security in Ethiopia.

Using primary data collected from 462 farm households, this paper aims to examine the impact of income diversification on rural household food security in Ethiopia. A propensity score matching model was employed to analyze the impact of participation in both agriculture and non-agriculture activities on household food security. The results indicate that age, education level, household size, number of contacts with extension agents, and numbers of livestock in tropical livestock units have a significant effect on household participation in both agriculture and non-agriculture sources of income generation. The propensity score matching result suggested that participation in both agriculture and non-agriculture would increase the rural household food security status by 10.6% to 19.5%, mainly due to a positive effect of additional sources of income generation from non-agriculture activities as witnessed in present and past studies. Therefore, to make considerable improvement on the food security situation, there is need to promote and scale-up on-farm, off-farm and non-farm income-generating activities in rural areas to diversify income sources so as to improve food security status of the rural households in Ethiopia.

Knowledge, attitude and practice towards malnutrition and micronutrient deficiency among male and female farmers in Ethiopia.

BACKGROUND: Despite a large body of literature on the nexus between knowledge, attitude and practice towards nutrition and gender, this nexus is likely to vary and is not clear in many societies, such as Ethiopia. OBJECTIVES: The study aimed to analyze the level of gender-based knowledge, attitude, and practice towards malnutrition and micronutrient deficiency using primary data collected from two regional states in Ethiopia. METHODS: Qualitative and quantitative data collection approaches were used. Qualitative data were analyzed using a narrative and content approach. Quantitative data were analyzed using descriptive statistics. RESULTS: Results indicate that female are generally more adept than male at identifying the symptoms of malnutrition. However, concerning vitamin A and iodine food types and its deficiency, male respondents had relatively better knowledge and consumption practice than female. Results show that there is very little awareness about biofortified and fortified foods. When we rate respondents, male had a relatively better understanding about fortified foods than their female counterparts. CONCLUSION: Findings can support development agents working to improve nutrition in Ethiopia to focus on improving community knowledge and perception of biofortified and fortified foods to improve diet quality through increased micronutrient intake. The majority of the respondents were aware of the importance of consuming micronutrient rich foods and had a positive attitude towards them. However, there is still a gap in practice. It may therefore require more targeted campaigns to increase the ability of community members to adopt best practices while reducing barriers to consumption of nutritious diet.

Food safety knowledge, attitude, and practice among male and female food handlers: Evidence from fruit and vegetable producers in Ethiopia.

Studies on the level of knowledge, attitude and handling practice towards food safety would help to determine the associated factors of knowledge, attitude and practice towards food safety; however, these studies did not explicitly address food safety concerns related to fruit and vegetables in Ethiopia. Men and women could have different levels of knowledge, attitude, and handling practice; however, these gendered effects were not addressed in previous studies. Using data collected in 2021 from 311 farm households in Ethiopia, this study aimed to analyze the level of knowledge, attitude, and handling practice of fruit and vegetable and associated factors among male and female food handlers. Data was analyzed using descriptive statistics, spearman's correlation, and econometric models (logit, multinomial logit and ordered probit). Education has a positive significant effect on knowledge, attitude and handling practices of fruit and vegetable handlers. However, the effect was higher in the females. No correlation could be obtained between knowledge and practices for the total respondents. However, knowledge had a positive but weak significant association with practices in the female group. We found a significant positive correlation between knowledge and attitude. These findings indicated that food safety knowledge of fruit and vegetable handlers will influence their attitude and a positive attitude would influence the practice in safe handling of fruit and vegetables. It therefore may require more targeted campaigns (i.e. from awareness creation to behavior change) to increase the ability of the community members to adopt best practices while reducing the barriers associated with consuming unhealthy diets.

Farmers' use of climate change adaptation strategies and their impacts on food security in Kenya.

Climate change threatens the sustainability of food production among farmers in Kenya who depend on rain-fed agriculture. To minimize the negative impacts of climate change, farmers have sought to adopt different adaptation strategies. This study investigates factors influencing farmers' choice of climate change adaptation strategies and associated effects on their food security in Kenya using data collected from 540 farmers from six counties. A multivariate probit, censored least absolute deviation (CLAD), and propensity score matching (PSM) models were employed to identify the determinants in the farmers' choice of climate change adaptation strategies, the number of adaptation strategies adopted, and the effect of climate change adaptation strategies on their food security, respectively. Results show that planting drought-tolerant crop varieties (55%), growing diversified crops (34%), growing early maturing crops (22%), and diversifying the sources of household income (18%) were the four major adaptation strategies used by the farmers in the study area. Younger farmers and those with higher education levels are more likely to use these climate change adaptation practices. The number of adaptation strategies used was positively associated with male farmers, education level, family size, land size, farm income, extension contact, training, and information access. The farmers who adopt one adaptation strategy have higher food security status (approximately 7-11%) than those who do not. If they adopt two adaptation strategies, their food security status increases by approximately 11-14%; if they adopt three adaptation strategies, their food security status increases by nearly 12-15%; and if they adopt four adaptation practices, their food security status increases by about 14-18%, compared to those who do not adopt any strategy. Thus, the farmers' climate change adaptation practices have positive food security effects in Kenya according to the number of adaptation strategies adopted.

Does exclosure restore woody species regeneration in degraded lands? The case of Loma Bosa District of Dawuro zone, Southwestern Ethiopia.

Exclosure becomes popular as a naming of the practice of excluding degrading agents from degraded lands for natural rehabilitation. However, its role on woody species regeneration in the Loma Bosa District of the southwestern Ethiopia has not been investigated. Therefore, this study examines the role of exclosure on woody species regeneration by comparing exclosure, open woodland, and degraded land areas. A systematic transect sampling method was employed to collect vegetation data in sampling quadrats, each with a size of 20 × 20 m, evenly distributed along parallel transect lines. All the woody plant species in each plot were identified and measured for DBH and height. Twenty-six woody species, representing 16 plant families, were recorded at the study area, of which only eight were recorded all in the exclosure, open woodland and open degraded land. Species Diversity Index (H') was 2.62, 2.38, and 1.56 for woody species in exclosure, open woodland area, and open degraded land area. Wood species density were 2225 ha-1, 1642 ha-1, and 297 ha-1 for exclosure, open woodland area, and open degraded land area, respectively. The distribution of the height and DBH of the recorded species in exclosure exhibited an inverted "J" shape pattern suggesting a healthy regeneration status of the important species, while others revealed irregular and less interpretable pattern. Overall results from this study indicated that exclosure is important for improvement of woody species regeneration in degraded lands in the study area.

Gender-based Decision Making in Marketing Channel Choice - Evidence of Maize Supply Chains in Southern Ethiopia.

We examine factors affecting the choice of marketing channels for maize among male, female, and joint decision-making farm households using data from households in Dawuro zone, southern Ethiopia. Econometric results suggest that female and joint decision-makers are more likely to sell maize to consumers or retailers in the main local market where the maize price is higher than to wholesale merchants directly from the farm. Individual decision-makers (male or female) who grow improved maize varieties are more likely to sell to wholesalers directly from the farm. This may be an indication of the effectiveness of joint decisions over individual decisions related to the market price. We also found that improved maize varieties distributed to farmers in the study area are of poor quality and that there is a lack of modern storage facilities so that farmers have to sell immediately after harvest during the lower price season. Thus, there is a need for policies promoting the distribution of high-quality maize seeds and encouraging investments in the establishment of modern maize storage facilities in the study area.

Gender differences in agricultural productivity: evidence from maize farm households in southern Ethiopia.

This study examines the impact of gender differences on maize productivity in Dawuro Zone, southern Ethiopia. Our study addressed the limitations of the previous studies in two ways. First, the study separately assessed gender differences in productivity between de facto female-headed households and de jure female-headed households and revealed that female-headed households are not homogenous. Second, the study separately examined the impacts of the covariates on male-headed households and female-headed households using an exogenous switching treatment effect model. We find the existence of gender differences in maize productivity between male-headed households and female-headed households. The maize productivity of male-headed households was overall 44.3% higher than that of female-headed households. However, if female-headed households received the same return on their resources as male-headed households, their productivity would increase by 42.3%. This suggests agricultural policy should target female-headed households to help reduce the productivity gap between male-headed households and female-headed households. Finally, the distributions of the gender differentials between male-headed households and female-headed households are more pronounced at mid-levels of productivity.

Prevalence of household food insecurity in East Africa: Linking food access with climate vulnerability.

The prevalence of food insecurity is much higher in East Africa than in other parts of the world. Climate change and associated variability are important contributors to food insecurity in the region. Using primary data collected in 2018/19 from Ethiopia, Kenya and Tanzania, this study examines the links between the prevalence of household food insecurity (the access to food dimension) and vulnerability to climate change in East Africa. The Household Food Insecurity Access Scale (HFIAS) was constructed to measure the prevalence of household food insecurity, and an ordered probit econometrics model was used to investigate the factors affecting the prevalence rates. The aggregate results show that 52% of the total sampled households in the region were food-secure; 15% and 26% were mildly food-secure and moderately food-insecure, respectively; and the remaining 7% were severely food-insecure. The ordered probit results suggest that exposure to climate change extremes and crop losses caused by these extremes significantly contribute to the prevalence of food insecurity across countries in East Africa. The results also indicate that households' adaptive capacity plays a significant role in reducing the prevalence of food insecurity. The demographic/human, social, financial, physical, and natural assets/capital of the household also play a significant role in reducing household-level food insecurity in Ethiopia, Kenya, and Tanzania.

The impact of adopting stress-tolerant maize on maize yield, maize income, and food security in Tanzania.

Productivity growth emanating from scientific advances offered by biotechnology and other plant breeding initiatives offers great promise for meeting the growing food demand worldwide. This justifies investments in agricultural research and development that have led to the development of stress-tolerant maize varieties (STMVs) in Africa. While most literature has documented the average impacts of STMVs on productivity, this paper is premised on the fact that benefits from technology adoption are not the same across household. The paper addresses this information gap by examining potential heterogeneity in yield, income, and food security benefits from of adopting STMVs using a sample of 720 maize-producing households from Tanzania. The dose-response continuous treatment effect method supported by an endogenous switching probit model was used to estimate the heterogenous impact of STMV adoption on the three outcomes of interest. Results show that, overall, the adoption of stress-tolerant maize varieties increased maize grain yield by about 1 ton/ha, maize income by about $62/ha. The adoption of STMVs also reduced the propensity to report mild, moderate, and severe food insecurity by 34%, 17%, and 6%, respectively. There are substantial idiosyncratic variations in the productivity, income, and food security effects depending on the scale of adoption, with a higher impact at lower dose levels of adoption. The heterogenous and pro-poor nature of STMV adoption is also revealed through nonparametric results showing higher productivity benefits among households that are less endowed with wealth and knowledge. These findings underscore the need for further scaling of stress-tolerant maize varieties for greater impact on the livelihoods of poor small-scale farmers in Tanzania.

Gender differences in the adoption of agricultural technology: The case of improved maize varieties in southern Ethiopia.

This study explores the role of gender-based decision-making in the adoption of improved maize varieties. The primary data were collected in 2018 from 560 farm households in Dawuro Zone, Ethiopia, and were comparatively analyzed across gender categories of households: male decision-making, female decision-making and joint decision-making, using a double-hurdle model. The results show that the intensity of improved maize varieties adopted on plots managed by male, female, and joint decision-making households are significantly different. This effect diminishes in the model when we take other factors into account. Using the gender of the heads of households and agricultural decision-maker, the current study did not find significant evidence of gender difference in the rate and intensity of adoption of improved maize varieties. The intensity of adoption of improved maize varieties is lower for female-headed households where decisions are made jointly by men and women, compared to the male-headed households where decisions are made jointly. As the economic status is a key driver of adoption of improved maize varieties, it is recommended that the policies and programs that aim at developing and disseminating quality maize seeds in southern Ethiopia should emphatically support economically less endowed but more gender egalitarian joint decision-making households, especially female-headed ones.
