(1) Background: Even though agriculture is the backbone of the Ethiopian economy, the improvements made regarding crop productivity appeared insufficient and had slow progress. Several studies suggest possible ways to identify the challenges in the productivity of the crop sub-sector. Nevertheless, there are gaps in the empirical literature in both knowledge and methods. The current study intends to identify the factors that affect growth in the productivity of teff, maize, barley, wheat, and sorghum crops. (2) Methods: Cobb-Douglass stochastic production function is estimated using a panel data set of the Living Standard Measurement Survey. To address the objectives of the study, a parametric estimation with a time-varying decay model with deterministic and stochastic components was adopted. (3) Results and Discussion: The effect of inputs on aggregate output was positive and significant at the 1% significance level, implying the presence of economies of scale. Variation in the inefficiency term explained 46.4% of the total variance in the composed error term. The average productivity of major crops was 6.19 per year. This study implied that technical change in the production of major crops increased by 22% with better use of available technology. (4) Conclusions and Policy Implication: The findings pinpoint that farmers should focus on technical change and intensification of improved agricultural inputs.

Food self-sufficiency has received attention from many nations with various economic orientations since it has been essential to achieving food security. Others countered that maintaining food self-sufficiency might be expensive relative to the advantages, even if it should be necessary for food security. Moreover, due to extraordinary climate instability and pervasive rural poverty, food insecurity is a bigger challenge now than it has ever been. Therefore, using cross-sectional data gathered from 120 sample families, this study assesses the level of food security among households and its determinants in the Wolayta Zone in Southern Ethiopia. By comparing the total amount of calories available for consumption per adult equivalent to the 2200 kcal minimal level of subsistence required per adult equivalent, the food security status of households was ascertained. To assess the state of food security at the home level, a probit model was used. According to the study's findings, 59.65% of the sample homes in the study area experienced food insecurity. Additionally, the findings showed that the most important variables positively connected with food security were literacy, land area, irrigation water utilization, and a few others. Age, female-headed households, family size, and the dependence ratio, on the other hand, have had a negative impact on food security. The results ultimately suggest that the majority of households experience food insecurity, which can be improved with the help of institutional investors, other government and non-government stockholders, and suitable policy and strategy.

This study was undertaken to assess the constraints of community participation on domestic solid waste management activities in sodo city, Ethiopia. Both qualitative and quantitative data were collected from primary and secondary sources. The primary data were collected from 204 households who were randomly selected from four kebeles (Fana, Gebeya, Gido and Selame) of wolayita-sodo city. The primary data were gathered through survey questionnaire, key informant interview, focus group discussion, and field observation. The secondary data were collected from central statistics authority, city municipality, published and unpublished sources. The collected data were analyzed by using descriptive statistics and binary logistic regression model. The result shows that participation of communities on domestic solid waste management was low. The result from binary logistic regression model revealed that the probability of household participation on domestic solid waste management was positively and significantly constrained by educational level of households, household income, and household access to main road, small-scale enterprise service coverage and supply of waste facility. On the other hand, sex of household head and marital statuses were negatively and significantly constrained the probability of household participations on domestic solid waste management. As a result, widening the horizon of education and training, expanding small-scale enterprise service coverage, supply of waste facility and provision of road infrastructure within the community was suggested to reduce constraints of community participation on domestic solid waste management.

This invention describes that the rate of input utilization is decisive for productivity growth of considered crops. The invention enhances the productivity of major crops like maize, teff, wheat, barley and sorghum crops. The sample was based on a panel data of (2011, 2013, and 2015) acquired from the Ethiopian socio-economic survey was used. The invention was scientifically analyzed using the basic fixed effect model and dose-response function under exogenous and endogenous treatment models. In the exogenous and endogenous treatment cases, households applying fertilizer have achieved actual different levels of higher outputs than their counterparts. In endogenous treatment, the household applying fertilizer harvested much higher output than those in the counterfactual condition. Moreover, inputs: fertilizer, seed, labor force, and farm capital utilization have a critical impact on the aggregate outputs of considered crops.
