Factors Influencing Household Livelihood Diversification: The Case of Kebri Dahar District, Korahey Zone of Somali Region, Ethiopia

,


Introduction
Livelihood diversifcation is an important strategy for income-generating activities for rural households in developing countries. Agriculture has remained the dominant livelihood strategy, contributing 15% of total GDP, 80% of smallholder farms, and employing approximately 175 million people directly in the labor force in sub-Saharan Africa [1]. Agricultural productivity is the lowest and even shows a decreasing trend, causing a decline in per capita cereal consumption at the national level [2]. However, the diversifcation of the livelihoods of rural households is no single activity, and the factors determining farmers "decisions for choosing and adopting diversifcation activities are diferent. For instance, the distribution of assets and wealth background status plays a crucial role in households" choice of what type of livelihood diversifcation strategy is appropriate for them.
Te determinant factors of livelihood diversifcation are very important in determining a household's food security status [3]. Livelihood diversifcation leads to livelihood outcomes consisting of improved food security, an increment in income, reduced vulnerability to shocks, and sustainable use of natural resources.
However, undiversifed livelihood options and complete dependence on agricultural products were the main problems that exacerbated food insecurity in rural areas. Te ability to diversify livelohood at all levels is often critical for the most vulnerable rural populations [4]. In many rural areas, agriculture alone cannot provide enough livelihood opportunities, but diversifcation may have a positive impact on the livelihoods of rural households both for consumption and market purposes. Resource-poor households use livelihood diversifcation as a survival strategy to cope with shocks and risky environments, whereby resource-rich households use livelihood diversifcation in an attempt to reap the benefts of development [5].
Furthermore, some empirical evidence on livelihood diversifcation is limited to nonfarm income generation, with little variation in how income afects other important outcomes such as food consumption, education, training, credit, dependency ratio, family size, and health [6]. Terefore, this study tried to respond to the gaps explained previously by investigating the determinant factors infuencing the diversifcation of livelihoods. Additionally, there is a wide diference in the literature on the share of nonfarm and nonfarm livelihood strategies [7]. About 33% of rural households engage in of-farm livelihood activities, indicating that income from farming is not sufcient to support the household's livelihood needs.
Most Ethiopians' livelihoods are agriculture-based, labor productivity is low, and large numbers of the population are net cereal buyers [3]. Due to the primary dependence on subsistence crop production in the country, harvest failure leads to household food problems due to the absence of offarm income opportunities, which leads to asset depletion and destitution at the household level [8]. Te Somali regional state has a long history of political and economic marginalization, which makes one of the poorest regions in Ethiopia acutely underserved in terms of electricity, water, and other infrastructure facilities such as roads and social services.
Kebri Dahar district is one of the drought-prone and vulnerable districts in the Korahey zone of the Somali Regional State of Ethiopia, which is characterized by permanent drought, malaria, and high temperatures, preventing people from working permanently. As a result, most of society does not have an interest in involving farmland. Instead, they depend on imported and donated food for consumption, which does not cover even household food needs. Te reason why the land was not cultivated during rainfall is unknown. Te purpose of this study was to identify the factors that infuence diversifcation in the study area.

Conceptual Framework of the Study.
Te framework helps policymakers to have broad plans to improve household livelihood activities. By reviewing many studies and actual-world situations, it was found that rural households' livelihood earnings were infuenced by institutional, physical and environmental, demographic, and socioeconomic factors ( Figure 1). However, no single factor can exist in isolation without the infuence of others. Terefore, this study was trying to assess the relationships of independent variables with the dependent variable, which gives us an outcome of either diversifed or undiversifed livelihood.

Description of the Study Area.
Kebri Dahar is one of the ten districts in the Korahey zone of the Somali region state of Ethiopia that is highly afected by climate-related risks such as drought, diseases of both humans and animals, and production failures.
Due to that problem, the district was selected purposively to investigate the issue of factors infuencing livelihood diversifcation. Te district is located in the eastern part of the region, bordered to the south by Kudunbur, to the west by the zone's Bodalay district, to the northeast by the zone's El-Ogaden district, to the north by the zone's Shaekosh district, and to the east by the zone's El-Ogaden district ( Figure 2). Tis district's average elevation is 706 meters above sea level, and temperatures range from around 37 degrees Celsius in April to 27.7 degrees Celsius in November. As a result, Kebri Dahar's average temperature is 31.6°C, with a latitude and longitude of 6.7417°N and 44.2621°E, respectively. Te district's area coverage was estimated at 9450.4 km 2 with an average annual rainfall of 1037 mm. During the most dangerous seasons, annual rainfall varies by an average of 90.2 mm [9].

Sampling Procedure and Sample Size Determination.
A multistage sampling technique was employed to select the representative household heads for this study. Te study district was purposively selected among ten districts of the zone knowing the background of the area to investigate the existence of the gap between diversifed and undiversifed based on the bases of livelihood activities for the food security of the rural household. Tree rural kebeles were selected through the lottery method in the second stage considering time, fnancial resources, and the representation of the district population. Based on the procedure, Darussalam, Dala, Ada, and Dalad kebeles were selected. Te total numbers of households in kebeles were 1000, 950, and 1025, respectively, which yielded a total of 2975 households frame. Te third stage involved the selection of household heads from the chosen rural kebeles by using systematic random sampling. Te total sample size was estimated to be 119 households using the following sample size determination formula adapted from Israel (1992). n � N/ 1 + N(e) 2 where N � the total population that was studied, n � the required sample size, e � the precision level, which is (9%), where the confdence level is 95% at P � ±5 (maximum variability). Te selected kebeles are composed of 2975 households frame. By replacing the abovementioned formula, it becomes 118.577, approximately 119 households. Ten, the distribution of sample size across the kebeles by using probability proportional to sample size is as indicated in Table 1.

Methods of Data Collection.
Gathering the required data based on qualitative and quantitative data by triangulating diferent methods, the following data collection methods were employed. Household survey: for a household survey of the study, closed questions were used for the interview ii) Sex of Respondent iii) Dependency ratio iii) Figure 1: Conceptual framework of the study. Source: authors' own constructed.
Advances in Agriculture 3 schedule of the HH heads. Te interview schedule was prepared in English and translated into the local language (Somali during data collection). Terefore, before collecting the data, a pretest was conducted to make the necessary modifcation.
Focus group discussion (FGD): in addition to the household survey, FGD was the most important data collection method to generate qualitative information. A total of six FGDs were conducted for two FGDs each kebele within a limited number of discussants in each FGD. Te participants of FGDs were infuential and well-experienced individuals from the communities in the study area such as model farmers and active individuals of the community. Te questions in the checklist were concerned with the specifc objectives areas whether livelihood diversifcation infuences household food security was considered as the guide to discussions, although the participants were contained major in age, male, and female, which have experience in the area background.
Key informant interview: it was conducted with different individuals and ofcials in the study district. Te frst three interviews were conducted with kebele administrators of sample kebeles (Darussalem, Dala, Ada, and Dalad). Te reason to have a key informant interview with the kebele administrator's level was the due to the fact that they have close relationships with both community members and it was possible to get important information at the grass-root level. Te second key informant interview was conducted with the district Food Security Coordination Ofcer. Te district Food Security Coordination, animal, and agricultural ofce have a responsibility to manage, coordinate, and follow-up the whole process of livelihood activity. Information about livelihood diversifcation, as well as challenges and opportunities and whether a diversifed household has met the primary objective of the program (i.e., food security), was gathered from the coordination ofce. Te third interview was held with the district administrator to get a complete picture of the household's income activity. To cross-check the validity of information obtained from the ofcial key informants, conduct the other key informant interview with individuals from the host community and administrators as part of the data collection process on the issue of the role of livelihood diversifcation on households' food security.
Field observation: in addition to the previously mentioned methods, feld observations were also made to supplement the data collection process. It includes observation of livelihood involvement such as farmingand nonfarming activities; natural resource management and its coverage in the area, social interaction at marketplaces, churches, and mosques, as well as livelihood diversifcation in household food security of selected kebele of the district.

Methods of Data Analysis.
Te information gathered from diferent sources was compiled in a way that was easy to manage. Types of data analysis, namely, statistics (descriptive and inferential) and econometric models, were used to analyze the data collected from sampled households. Te qualitative data were analyzed through narration, summarization, and discussion and interpreted to obtain accurate results on the role of livelihood diversifcation of livelihoods on the food security of rural households food security; whereas the quantitative data were analyzed using simple descriptive statistics such as frequency, mean, and standard deviation. Te signifcance group diferences test (t-test and chi-square test) was used. Data analysis was conducted using Statistical Package for Social Sciences (SPSS) version 20 to examine the role of diversifcation for rural households' food security of rural households in general and the analysis of diversifcation strategies, determinant factors of livelihood diversifcation, and impact of livelihood diversifcation for food security in particular.

Statistical Analysis.
Te study used one-way ANOVA (Analysis of variance) to compute whether there are diferences among groups with diferent livelihood strategies concerning the average of the continuous dependent variable. While the Chi-square test was conducted to test the association between categorical variables and the livelihood strategies identifed.
Lastly, multinomial logistic regression (MLR) was used to test the efect of dependent variables (metric or dichotomous) on the dependent variable with more than two categories. In this study, the dependent variables, livelihood diversifcation, have three categories, and food security status is an outcome that fts MLR [10]. Before the estimation of the logistic regression model, the existence of multicollinearity was checked among explanatory variables. Te correlation between two variables is simply the square root of R 2 , combined with a sign indicating a positive or negative association. If we see values close to 1 or −1 that indicates variables are strongly associated with each other and we may have multicollinearity problems. Te easiest way to measure the extent of multicollinearity is to simply look at the matrix of correlations between the individual variables. In addition, the variance infation factor (VIF) was used to check the degree of linear relationships among continuous explanatory variables, and the contingency coefcient was used to check for association among discrete variables. VIF for all variables used in the study was less than 10, and thus, the nonexistence of association between the continuous variables included in the model was confrmed.
2.6. Econometric Model Specifcation. Both Probit and logit analysis are well-established approaches in the literature to estimate dummy dependent variables [11]. However, when there are many observations at the extremes of the distribution, then logit is preferred over probit [12]. [13] also reported that the logit model is computationally easier to use than the other type. Terefore, the logit model was applied in this study to assist in estimating the probability of livelihood diversifcation that can take one of two values, diversifed, or undiversifed. According to Gujarati [14], the functional form of the logit model is presented as follows: Following the work of [15], the multinomial logit model can be specifed as follows. Let UIJ denote the utility that the household ί gets from choosing an alternative activity.
where Y j varies and X i remains constant between alternatives and is a random disturbance term refecting intrinsically random choice behavior, measurement or specifcation error, and unobserved attributes of alternatives. Let also P ij (j � 0, 1, 2, 3, 4, 5, 6, 7) denote the probability associated with the of/nonfarm activities choices of household i with; j � 0 if the household does not participate in any livelihood activity, j � 1 if the household participates on farm livelihood activity, j � 2 if the household participates in of-farm livelihood activity, j � 3 if the household participates nonfarm livelihood activity, j � 4 if the household participates on-farm plus of-farm livelihood activity, j � 5 if the household participates on-farm plus nonfarm livelihood activity, j � 6 if the household participates of-farm plus nonfarm livelihood activity, and j � 7 if the household participates combination of livelihood activity. Ten, the multinomial logit model can be given by the following expression: By setting Y 0 , the multinomial logit model can be written as follows: (j � 1, 2, 3, 4, 5, 6, 7) and Pi°� Te slope tells how the log odds in favor of a given livelihood diversifcation change as independent variables change. If P i is the probability of a household being diversifed, then 1 P i indicates the probability that a given household is undiversifed.
Furthermore, on the behavior of the impact of livelihood diversifcation on household's food security, the probit regression model was used by analyzing the impact of independent variables on household food security status which is a dependent variable by model analysis taking the value of 1 for food secure household and 0 for food insecure household.

Defnition of Variables and Working Hypothesis
Dependent variable: the dependent variable of the study was the diversifcation of the livelihood, which is categorical of containing on-farm, of-farm, nonfarm, and a combination of livelihood activity ( Table 2). Based on the number of livelihood activities involved by the households' it can be further classifed as diversifed and undiversifed on the basis of the number of livelihood activities. Te former was obtained by asking respondents the number of livelihood activities they engage such as on-the-farm, of-farm, and nonfarm activities. Explanatory variables: it was hypothesized as a farmer's decision to diversify or reject multiple components of livelihood activity to gain a proft was highly infuenced by diferent factors. Based on previous studies, the researcher hypothesized these factors can be categorized as physical, environmental, socioeconomic, demographic, and intuitional factors. Tese factors were used to determine farmers' decision to diversify or not ( Table 2). For example, the following independent variable in the study area was operationalized to infuence livelihood diversifcation as an outcome by using descriptive statistics, multinomial logit regression model, and former empirical literature studies shreds of evidence. Sex of HH: it is a dummy variable representing the sex of the house head (HH) of men and women that have diferent access to resources and opportunities, women are subject to discrimination in labor, credit, Advances in Agriculture and a variety of other markets and they own less property compared to men. Terefore, it was expected that sex and livelihood diversifcation are negatively related in female-headed households [5,16] also revealed that the sex of the household is one of the important driving forces toward occupational livelihood diversifcation. Age HH: it is a continuous variable that measures the age of the head of the household in years. Rural households mostly devote their time to farming activities. As the age of households increases, they can acquire more knowledge and experience about livelihood diversifcation benefts and the feasibility direction of household food security. Hence, in this study, the increase in age is hypothesized to be positively related to the diversifcation of livelihood activity [17]. Access to transportation: it is among the important factors that afect the livelihood activities of a household. Any kind of weather-driven vehicle, on foot and animal back, has a high infuence on diversifying their livelihood activities. Households who have access to vehicle roads had nonfarm livelihood opportunities. Terefore, the relationship between access to transportation used by respondents and diversifcation was expected to be positively signifcant ( Table 2). Te educational level of the household head: education level refers to the years of schooling of the HH head in years. Investment and reproductive choice are all infuencing the household heads' level of education [18]. However, education and household livelihood have a direct relationship in the context of subsistence farming; literate farmers are expected to be better than their illiterate counterparts in several ways. Education determines the ability of an individual to fnd a new job. Tis variable was expected to have a positive relationship with the diversifcation of livelihoods ( Table 2). Dependency ratio: it is the ratio of dependent people younger than 18 years and older than 64 years to the working-age population those ages 18 to 64 years [19]. It is computed by using the following formula.
Dependency ratio � number of people aged 17 and people age 65 and above number of people age between 18 − 64 x100.  [20]. Distance from the market: it refers to the nearness or farness of the household's residence from the nearest marketplace within walking hours. It was measured by the walking hour (Table 2). Access to the market and other public infrastructure can create opportunities for more income by providing diversifcation of livelihood strategies through non-and of-farm employment and  Advances in Agriculture easy access to input and transport facilities; households near the center of the market have a better chance to increase diversifcation [3]. In this study, this variable was expected to be negatively related to livelihood diversifcation. Participation in a productive safety net program: the overall objective of the program is to improve the food security of food insecure society and food sufciency for those unable to achieve food security, of male and female members of chronic food insecure households in chronically food insecure districts achieved. Te program allows benefciaries to involve in diferent activities which are called cash for work or food for work. So, it is expected to have a positive relationship with livelihood diversifcation and improve the food security of the household. Membership to cooperatives: membership in cooperatives represents whether a household is a member of cooperatives or not ( Table 2). Cooperatives worldwide are committed to the concept of mutual self-help. Tis makes them natural tools for social and economic development and provides signifcant additional benefts to communities and social systems. Formal as well as informal associations, such as indigenous cooperation groups, enforce widely agreed standards of behavior and unite people with bonds of community solidarity and mutual assistance. Membership in cooperatives also increases a household's access to services that might be granted by being a member [3]. Tis variable is expected to be positively related to the diversifcation of livelihoods. Saving: household savings are a vital source of start-up fnance for running multiple livelihood activities [21]. Households that combine agricultural and nonagricultural livelihood activities predominantly use saving with mixed livelihood activities. Terefore, this variable is expected to be signifcantly related to livelihood diversifcation. Access to credit: it refers to access to credit services. Farmers use credit primarily to buy agricultural inputs, and also, they used it to invest in nonagricultural activities which supplement their farm income. Alobo Loison [22] said that credit encourages the investment of farmers to augment their farm productivity and widen their participation in nonfarm livelihood strategies. Credit utilization and livelihood diversifcation were expected to be signifcant and positively associated. Access to extension contact: extension contact is a continuous variable that measures the frequency of extension contact of the household head per year ( Table 2). Extension contact plays an important role in improving household food security for the household by promoting knowledge, training, and livelihood information to households with high extension contact. On the contrary, other studies revealed that farmers who have better extension contact have better access to livelihood information and technical assistance that increase agricultural production and productivity [23]. However, the high frequency of extension interaction by household heads had a positive impact on diversifcation [24]. Moreover, in this study, extension contact was expected to have a statistically signifcant and positive impact on food security.

Demographic and Socioeconomic Characteristics of
Respondents. Among the total respondents, 20.2% were single, 65.5% were married, 5.9% were divorced, and the remaining 8.4% of the respondents were widowed (Figure 3). According to this study, single and married respondents are low-viability participants as compared to their counterparts because they are independent in taking any responsibility based on their interests without any infuence from their family or husband. So, they can participate freely in livelihood activities without any intervention.

Constraints Related to the Diversifcation in the Study
Area. Institutional challenges such as access to clean and crop irrigation water, a lack of health care, and a lack of formal savings institutions are major obstacles to households diversifying their livelihood activities. As a result, the institutions that can limit households' livelihood options have been appointed based on information from respondents and FGD. Te information earned from 119 sampled households (Table 3) indicated that 52.9% of them responded that they did not have safe water for drinking, and 80.7% of them responded that they had faced illness during the last 12 months, which prevented them from following up on livelihood activities. Furthermore, the key informant interview provided data that supports the respondent's reaction to water and healthrelated issues. Furthermore, 69.7% of respondents complained about not having access to saving institution services, whereas 30.1% had access to saving institution services, which can be classifed as follows: only 4.2% of them save their money in Advances in Agriculture formal institutions such as the Commercial Bank of Ethiopia, while 10.9% save at home, 10.1% save in equipment, and 5.9% save by purchasing animals for future use (Table 3). Furthermore, as mentioned in the focus group discussions and key informant interviews, the major barriers to livelihood diversifcation include market distance and information, a lack of telecommunication and transportation facilities, a lack of access to society-appropriate credit, a lack of contact with extension agents, a lack of agricultural inputs, and Prosopis julifora' dominance of farming land. Tis fnding is consistent with that of reference [25], which states that lack of market access and knowledge limitations about nonfarm activities are the major factors discouraging households from engaging in diversifcation activities, which account for 54.6% and 15.2% of the households in the study area, respectively. Even though the federal government of Ethiopia has developed various policies, strategies, and programs designed to improve the livelihoods of the people by reducing poverty and food insecurity [26]. Eventually, existing institutional responses were more oriented toward emergency assistance and asset protection. Nevertheless, future intervention needs to consider the new enabling pathways and consider pastoral development as an integral part of urban development rather than treating it purely as rural development in order to increase the adaptive capacity of the pastoralist communities through livelihood diversifcation programs in both the short and long terms [27].

Livelihood Diversifcation Strategies of Respondents.
Te livelihood strategy of the study area encompasses both agricultural and nonagricultural livelihood activities based on the household's ability to exercise the diferent livelihood activities in aspects of knowledge, skill, and experience.

Perception of the Respondents on Livelihoods of Diversifcation Beneft
Ability. Te quality and proftability of livelihoods are important factors infuencing a household's ability to engage in a variety of livelihood activities. Approximately, 23.5% of respondents believe that relying solely on agricultural activities can meet household livelihood needs by promoting agricultural products as less durable and more benefcial than nonagricultural activities (Table 4). Furthermore, 29.4% believe nonagricultural activities are more benefcial than agricultural activities, while 47.1% believe a combination of activities can meet the household livelihood goal (Table 4). Interestingly, this can be understood to mean that households that involve a larger stock of livestock achieve their livelihood needs by relying on agricultural activities alone. Similarly, livestock smallholders encourage household livelihood needs to be achieved through a variety of livelihood activities.
Tis is consistent with the study fndings [10], which found that 40.7% of the respondents are involved in agricultural activities such as crop production and livestock, while 52.5% encourage participation in a variety of livelihood activities. Tis means that increasing the number of livestock has a strong negative impact on households choosing nonfarm livelihood activities because they perceive a lack of sources of feeding their family through livestock sales.

Te Role of Domesticating Livestock for Livelihood
Improvement. Livestock is the backbone of livelihood development and economic activities in the Somali region in general and particularly in the study area. According to the responses, approximately, 82.4% of respondents in this study stated that the reason for raising livestock is to sell and use their products, while 15.1% and 2.5% stated that the reason for raising livestock is to sell and purchase food and to sell during a livelihood emergency, respectively. Most of the types of livestock found in the study area include camels, goats, sheep (shoats), cattle, and donkeys. However, livestock plays a signifcant role in the improvement of people's livelihoods in both rural and urban areas of the study, which is interdependent on the exchange of goods in the market between rural and urban people. For example, in the region as a whole, most of the populations are pastoralists or pastoralist-based mobile communities, even though, currently, there is an improvement in their mobility relative to permanently installed communities. Moreover, most of their lives depend on domestication and the purchase of livestock.

Current Diversifcation Status of the Study Households.
Livelihood diversifcation was categorized in terms of livelihood activities such as on-farm, of-farm, nonfarm, and a combination of livelihood activities. A household that   Advances in Agriculture involves more than one source of income activities can be considered a diversifed household, and a household that involves fewer than two sources of livelihood activities can be considered an undiversifed source of livelihood activities. Based on that information, 52.9% of them were diversifed households, while 47.1% of them were undiversifed households ( Figure 4). Following the physical observation of respondents, participating in a single source of livelihood activity seems better as compared to multiparticipant livelihood activities. For instance, undiversifed households have fewer opportunities to improve food security due to their limited sources of income. As a result, households that diversify their livelihood activities are less vulnerable than those that do not diversify their livelihood activities. Tis agrees with the study of Gebru et al. [28], who stated that 83.1% of the sampled households were able to diversify by involving a combination of livelihood strategies, while 16.9% of them were unable to diversify their livelihoods because they lacked the means to engage in any system of income-generating activities away from agriculture. Livelihood diversifcation is a strategy that can boost farmers' income and promote sustainable land management practices [29], especially among richer households with favorable agricultural conditions, where livelihood diversifcation is driven by motivations to increase income or accumulate wealth [14,30]. Although the study households, like other parts of the country, engaged in diferent livelihood activities in addition to basic agricultural activities, this fnding indicated that 47.1% of the sampled households were unable to diversify their livelihoods, where most of them involved a single livelihood activity and others involved fuctuating livelihood activities based on external support (Figure 4).

Inferential Statistical Tests.
Te results of the independent t-test and chi-square test analysis are presented separately as continuous and discrete variables, respectively. Tese tests help see the relationship between the variables and the mean diferences between diversifed and nondiversifed households.
Terefore, in the t-test, six continuous variables were hypothesized to check the determinant factors infuencing livelihood diversifcation activities (Table 5). Te results of continuous variables show that only the age of the respondent was found to be 5% statistically signifcant in the mean diference between nondiversifed and diversifed households (Table 5). Tus, insignifcant variables may infuence the livelihood options of households diferently among diversifed and undiversifed households.
Te chi-square test found that the head of the gender of the household and access to credit were signifcant at a probability level of less than 5% in infuencing the decision choice of households to diversify or not diversify (Table 6).

Determinant Factors Infuencing Livelihood Diversifcation in the Study Area.
A multinomial logistic regression model was used to demonstrate the relationship between independent variables and the dependent variable. To analyze the determinant factors that infuence households to choose and adopt diversifcation when the dependent variable is categorical with multiple outcomes, it is always advisable to check the relative ftness of the model before directly estimating. In this regard, the model is a good ft for the data because the MNL model result was fairly revealed with a pseudo R 2 of 58%, which means that 58% of the independent variables explain the dependent variable. A low R 2 value means that diversifed households do not have many distinct characteristics overall, and as such, fnding a good match between diversifed and nondiversifed households becomes easier [31].
Generally, the multinomial logistic regression model investigation found that three livelihood activities were statistically signifcant, including farm, farm, and nonfarm, but the combination of livelihood activities was not signifcant.
Sex is a dummy variable that is measured as either a male or female head of household. Te model result indicates that the sex of the household head signifcantly infuences the diversifcation at a 1% (P � 0.00) signifcant level (Table 7). Terefore, according to prior expectations, the sex of the respondents positively and signifcantly afects the diversifcation of the household's livelihood. Tis implies that other factors remain constant; being a male household head is more likely to diversify than its female counterparts. Te possible explanation for this would be that male-headed households have a better opportunity for resource control, interaction with others, agricultural technologies, and social perception of masculinity. All these increase participation in livelihood activities and diversify more than female-headed households by a factor of 16, 12, and 4.6, respectively, in the abovementioned activities. Tis result is similar to that of Zakaria et al. [17].
Age: age was found to be signifcant at 1% (P � 0.002) and had a negative infuence on diversifcation. Holding other things constant (Table 7), as age increases by one year, the probability of households engaging in on-farm, of-farm, and nonfarm livelihood activities declines by 0.940, 0.890, and 0.922, respectively. Te possible reason is that young household heads are relatively more educated and informed people who are ready to accept better technologies and search for alternative livelihood opportunities for their future endeavors. Old-age household heads are immobile to change their livelihood activities. Tis study is in line with that of Fitsum [18] and Gebru et al. [28].
Household head's educational level: its continuous variable measures the years spent in education of the household head. As the model result, education was found to be signifcant at a 1% (P � 0.00) probability level and infuenced on-farm livelihood activity negatively. As HH heads spend one year in education, the probability of on-farm livelihood diversifcation declines by 0.307, holding other things constant (Table 7). Because educated people do not like to diversify their livelihood options based on on-farm   livelihood activities, they prefer respectable salaried jobs and self-employment livelihood activities. Tis fnding is similar to that of Kassie et al. [29], who found that the educational level of farm households has a negative impact on livelihood diversifcation, as educated farmers may employ better farm technologies.
Dependence ratio: it is a continuous variable measured in the number of people in the family who are economically inactive due to youth, old age, or other circumstances such as illness and physical or mental inability. It was expected to have a negative relationship with the diversifcation of livelihoods. However, based on the model results, this variable was found to be signifcant and to have a positive association with the decision to choose household nonfarm livelihood diversifcation at a 1% (P � 0.002) signifcance level ( Table 7). As a dependent member in the family increases by one, the probability of livelihood diversifcation increases by 1.822 percent, keeping other factors constant. Te possible reason is that when one additional dependent member is added to the household, the economically active members of the household increase the option of enhancing livelihood activities through nonfarm livelihood diversifcation strategies. Tis fnding is consistent with that of Abawa Tizazu et al. [32] and agrees with that of Dessalegn and Ashagrie [33].
Tropical Livestock Unit (TLU): it is a continuous variable measured in the number of cattle owned by households (TLU). Te TLU was found to be positive and 1% (P � 0.002) signifcant enough to infuence on-farm and of-farm livelihood diversifcation (Table 7). By holding other factors constant, as TLU increases by one unit, the probability of livelihood diversifcation rises by a factor of 1.042 and 1.071 for on-farm and of-farm livelihood activities, respectively. For example, households that own more livestock have the opportunity to participate in other livelihood options compared to households that have fewer or no livestock. Tis result is in line with that of references [15,34]. Tis would suggest that it had a positive efect on farm and of-farm livelihood diversifcation because farmers with a larger stock of livestock had more money to invest in onfarm and nonfarm activities. Terefore, to be able to bring about a positive change in well-being, natural capital (livestock) is exchanged for diferent assets. Abawa Tizazu et al. [32] discovered that the prior expectation of this variable was consistent with their fndings.
Te negative association between livelihood diversifcation and the number of TLU implies that herd size creates a better opportunity to earn more income from livestock production and helps farmers fulfll family requirements, including food consumption.
Market distance: it is a continuous variable measured in the distance from a household's residence place to the nearest market in km. As expected, market distance is found to be signifcant at a 5% (P � 0.002) probability level and negatively infuences nonfarm livelihood diversifcation ( Table 7). As the market distance increases by one km, the probability of nonfarm livelihood diversifcation declines by a factor of 0.647, holding other factors constant. Te market may facilitate individuals' involvement in all types of livelihood options, and the likelihood of individuals diversifying beyond agricultural practice decreases as the market distance from their resident villages increases. Tose households that live near the market have a greater opportunity to engage in other income options beyond their usual pastoral activities, such as wage labor and petty trading, and market brokering. Tis conclusion is consistent with [34].
Transportation types: It is a continuous variable measured in the availability of transportation services for their products in the market. As expected, this variable was found signifcant at a 10% P � 0.05) probability level and infuenced of-farm livelihood diversifcation negatively ( Table 7). Holding all other variables constant, the probability of of-farm livelihood diversifcation falls by a factor of 0.605.
Te possible reason is that the majority of the respondents economically depend on livestock marketing and selling food for household consumption, followed by the unavailability of access to permanent vehicle transportation. Most of the respondents use foot travel and animal back-tomarket exchange of goods. For example, as livestock marketing distance increases, the chance of participation in offarm livelihood activities decreases. Tis is in line with the fnding of reference [25], which revealed the problem of the availability of the market for their products.
Saving habit of household head: it is a dummy variable that measures whether households saved money or not. Te model result indicates that the saving habits of household heads signifcantly and negatively infuence farm and nonfarm livelihood activities at 10% and 5% (P � 0.059 and 0.017) statistically signifcant levels, respectively ( Table 7). As the access to saving services increases by one unit in formal institutions, the probability of on-farm and nonfarm livelihood activities declines by a factor of 0.355 and 0.245, respectively, keeping other things constant. Although saving is a mechanism that changes production destruction and conformists during drought occupancy as compared to nonsaving, the possible reason that infuences this variable negatively is that the majority of the respondents did not have a formal institution to save their money. Instead, their daily income was used for daily food consumption or they saved at home and bought an animal for future use, which is highly susceptible to climate occurrence risk events.
Participation in a productive safety net program: it is a dummy variable that indicates whether or not a household receives outside assistance in the form of food or money. Te result of the MNL regression model revealed that participation in a productive safety net program (PNSP) was found to have a positive and statistically signifcant relationship with the diversifcation of of-farm income at a 10% (P � 0.055) level of statistical signifcance (Table 7). Holding all other variables constant, increasing access to PNSP by one unit of formal food or money donation increases the likelihood of of-farm livelihood diversifcation activities by a factor of 2.987.
Terefore, by increasing the number of rural households participating in productive safety net programs, household members have the opportunity to enhance the total income of the household, which plays an active role in improving and smoothing the problems of household food security. Such eforts can strengthen social networks, children's schooling, saving habits, and investment options that help households diversify other livelihood opportunities like trading and improve their livelihood as a whole. On the other hand, sometimes PNSP can afect the home by encouraging dependence on others' hands unless the government and other stakeholders are aware through training that the purpose of the donation is to escape poverty and related challenges but not sleep. Te study coincides with the fndings of Titay et al. [3].
Access to credit: it is a dummy variable that measures whether or not households have access to credit. Contrary to popular belief, household likelihood diversifcation based on nonfarm livelihood activities was found to be negatively and statistically signifcant at 1% (P � 0.001). As access to credit increases by one unit at formal donation institutions, the probability of livelihood diversifcation decreases by a factor of 0.099, keeping other factors constant (Table 7).
Although there are no more formal savings and credit institutions in the study area, households observed in the area have low interest rates on credit receipts.
Except for the returnable interest-free amount from relatives and friends, because of cultural and religious afairs, access to credit has negatively infuenced livelihood diversifcation based on nonfarm, whereby there are insignifcant relationships with on-farm and of-farm diversifcation activities. Tis study is consistent with the study of Asfr [23], who found that access to credit services harmed livelihood diversifcation because farmers who have access to credit may be inclined to purchase fertilizers to improve their agricultural production and productivity rather than diversify their livelihoods. On the other hand, this fnding contradicts the fndings of Gebru et al. [28]. Also, the fndings of Arega et al. [35] on access to credit showed a positive and signifcant correlation with the annual income of households. Access to credit services was found to have a positive efect on the diversifcation of livelihoods. Moreover, they concluded that giving credit to resource-poor farmers improved livelihood diversifcation [36].
Membership in the cooperative: it is a dummy variable that measures whether a household is a member of a cooperative organization or not. Te prior prediction of cooperative organization membership was found to be positive and statistically signifcant at 5% (P � 0.050) with household likelihood diversifcation based on nonfarm activities as predicted. By holding other factors constant, as access to membership in a formal cooperative organization increased by one unit, the probability of nonfarm livelihood activities increased by a factor of 2.992 (Table 7).
Te possible reason is that households that are members of formal cooperatives gain benefts such as sharing income and labor, access to credit, reduced individual transaction costs, updated market information about production and productivity such as inputs and farm equipment, and working in collaboration for goals. Te result agrees with the fndings obtained by reference [28].
On the other hand, the model result on membership in the cooperative in the study kebele contradicts the key informants' interview by stating that the society does not encourage members to maximize their income cooperatively through agricultural and nonagricultural activities or by participating in a combination of livelihood activities. Tis indicates a weak cooperative organization in the area, which was also supported by focus group discussants. According to the focus group discussion, cooperatives are simply being advised to focus on diversifying and participating in different activities rather than a more active collaboration between members in the study area for the achievement of improved food security.

Te Infuence of Extension Contact on Livelihood
Diversifcation. Efective extension contact infuences livelihood diversifcation in response to drought; it is critical to recognize seasonality fuctuations in order to be aware that livelihood activities take place at diferent times of the year. For instance, extension agents have to provide training and information at the household and community level. Te impact of diversifcation on food security has several compounding factors. While diversifcation usually means increased income for a household, it may depend on the extent to which it has disrupted household farming and whether the income derived is sufcient for food purchases and farm investments. Agricultural extension workers are important for strengthening the links between agricultural inputs and outputs.
As a result, according to the information elaborated during the interview, only 2.5% of respondents reported having a large number of extension contacts, while 16.8% reported having only one extension contact. As a result, 17.6% and 28.6% of the sampled respondents responded to relatively more and less contact, respectively. Approximately, 34.5% of the sampled respondents stated that they had no extension agent or worker. In general, 80.7% of the study population was dissatisfed with the extension service ( Table 8).
As a result, problems exist in the study area's kebele of the Kebri Dahar district. Tis fnding is in line with the FGDs' saying that involvement in nonfarm livelihoods highlights the greatest constraint to diversifcation as a lack of skilled provision agents. Tese include both fnancial skills and basic managerial skills to ensure the sustainability and growth of enterprises. Community members engaged in diversifcation either had the skills passed down in the family or, at one time, benefted from some training. Tis means that teenagers who wish to engage in nonfarm livelihoods

Advances in Agriculture continue to be constrained by a lack of training opportunities and local support.

Conclusion and Recommendation
According to the study's fndings, characteristics such as the household's head's age, education, market distance, access to credit, mode of transportation, and saving habits have a negative and statistically signifcant efect on livelihood diversifcation. Whereas, cooperative membership, participation in the Productive Safety Net Program (PNSP), dependence ratio, and holding in the Tropical Livestock Unit (TLU) were found to have a positive and statistically signifcant efect on livelihood diversifcation. Te results of the study indicate that although individuals from the area of study have the opportunity to engage in a wide range of diferent livelihood activities, the vast majority of them are involved in agriculture. However, more than half of the households in the study area do not use multiple livelihood diversifcation strategies to make their livelihoods more diverse.
Moreover, based on key fndings, the government and nongovernmental organizations should expand livelihood options in the study area, but they should also pay due attention to diversifying livelihoods, as the region is notorious for food insecurity and diversifcation implies household food security. Te majority of respondents are illiterate, which implies that conventional agricultural practices are also uninformed about nonagricultural means of subsistence. According to the aforementioned conclusion, they lacked access to savings and loans, which hindered the diversifcation of their livelihoods. Terefore, they should encourage the participation of family heads in both agricultural and nonagricultural businesses, pursuing culturally acceptable credit access and enhancing saving practices. Rather than educating families about reliance, donor organizations should intervene in development initiatives. Te district administrator should prioritize the area's infrastructure development, such as the allocation of transportation facilities, extension contact training, and electricity, because it infuences the household's participation in various income-generating activities, which implies household food security. Since fewer studies were carried out than those reported on the topic of livelihood diversifcation and food security, researchers should examine doing further studies in this area [37].
