Abstract

This study analyzed households’ food insecurity and its determinants along with the coping mechanisms opted against food insecurity and shortage in Assosa zone, western Ethiopia. The study used a primary data collected from 276 randomly selected households for 7 consecutive days from each sample using weighed records method. In addition, focus group discussions and key informants interview were also used. This study employed descriptive statistics, food insecurity index and Tobit model to analyze the data. The finding of the study revealed that, in the study area, the incidence of food insecurity was 53.62%, with the depth and severity of food insecurity being 16.84% and 7.32%, respectively. The study finding also pointed out that the mean kilocalorie intake of food insecure households was 1440.37kcal/AE/day, with the minimum and maximum being 597.65 kcal and 2048.13 kcal, respectively. Furthermore, the estimated Tobit model result revealed that age of the household head, family size and off-farm and non-farm income positively affected extent of households food insecurity; whereas access to irrigation, farm income, distance to market and access to credit negatively affected the extent of households’ food insecurity. Moreover, the study also identified that reducing meal size, reducing frequency of meal served, working as a daily laborer and selling livestock’s were the top four main coping mechanisms opted against food insecurity and/or shortage. Therefore, to reverse the incidence, future interventions should focus on the aforementioned factors to build the capacity of households through enhancing their access to human, financial and physical capital.

Introduction

Food is both a basic need and a human right as enough food in terms of quantity and quality for all people is an important factor for a healthy and productive life as well as for a nation to sustain its development (FAO (2014); Sani and Kemaw 2017). Besides, enough food in terms of quantity and quality is a key for maintaining and promoting political stability and insuring peace among people (Idrisa et al. 2008). However, reports indicated that about 1.4 billion poor people were living on less than US$1.25 a day and 1 billion of them live in rural areas where agriculture is the main source of livelihood, especially in sub-Saharan Africa and Southern Asia (IFAD 2011). Furthermore, FAO (2015) reported that about 795 million people in the world were food insecure, with many more suffering from ‘hidden hunger’ caused by micronutrient or protein deficiencies. Moreover, different studies depicted that food insecurity occurred in most countries to varying degrees, and 75% of the food insecure people lived in rural areas of developing countries, in which two thirds of these lived in just seven countries (Bangladesh, China, Democratic Republic of Congo, Ethiopia, India, Indonesia and Pakistan) (Keatinge et al. 2011; Khush et al. 2012; Sani and Kemaw 2017).

As a part of Africa and developing world, Ethiopia is one of the most food-insecure and famine affected countries as large portion of the country’s population has been affected by chronic and transitory food insecurity (Abduselam 2017). Over 30% of the population is below the food poverty line, unable to afford the minimum caloric intake for a healthy and active life (CSA (Central statistical agency) 2014). Furthermore, FAO (2012) finding figured out that 52% of the rural population was food insecure i.e. consume below the minimum recommended daily intake of 2100 kcal/ AE /day, which led the rural households to temporarily depend on relief food assistance. As a result, more than 8.5 million people were in need of emergency food aid and assistance (WFP 2017). Moreover, under-nutrition has been a persistent problem as 44% of children in the country were stunted, 10% of children were considered to have low weight-for-height (wasting) and 29% of children were considered to have underweight (low weight-for-age). Besides, under-nutrition was predominant in rural areas in which stunting accounts for 46%, wasting accounts for 10%, and underweight accounts for 30% of rural children in the country (CSA (Central statistical agency) 2011).

The western part of Ethiopia, Assosa zonein particular, is hit by high degree of incidence of food insecurity as agricultural production and productivity is highly vulnerable to climate variables (Sani and Kemaw 2017). In addition, Assosa zone is characterized by erratic and unreliable rainfall, land degradation, low per capita, poor infrastructure development, vulnerable groups (landless and the poor without assets, very small and fragmented land holders, female- headed households, families with large size, drought and pest affected households) which cause low agricultural production and food deficit in the area (Asfir 2016; AZBARD (Assosa Zone Agriculture and Rural Development Office) 2015). To reverse the food insecurity situation, the government has been formulating and implementing long-term strategies (such as Agricultural Development Led Industrialization, Growth & Transformation Plan I and Growth & Transformation Plan II)—which takes ensuring food security as its core objective (FAO 2012). In addition, to reduce the incidence of food insecurity households use different kinds of coping mechanisms in order to improve their livelihood. As to Gemechu et al. (2015) finding there is improvement in food security status of households in the country that shows the role of improvement in livelihood assets as well as investment strategies and policies that promoted households food security and concluded that there is still room for improvement. But, the improvement programs to be effective, they should be supported by location specific empirical evidences (Van der Veen and Tagel 2011). To this end, there is limitation of information on the issue in the study area. Hence, this study analyzes extent of food insecurity and its determinants along with the coping mechanisms opted by households against food insecurity and shortage in the study area. Thus, it addresses what factors affect households’ extent of food insecurity and what coping mechanisms have been used by households against food insecurity and shortage in the study area. Various studies conducted in Ethiopia mainly focused on food availability and access dimension (Girma 2012; Mesfin 2014; Nigatu 2011; Arega 2015; Okyere et al. 2013; Hussein and Janekarnkij 2013; Motbainor et al. 2016) and others adopted 24 h or seven day recall method to capture the utilization dimension (Gemechu et al. 2015; Zemedu and Mesfin 2014; Beyene & Muche, 2010) to address households’ food security and its determinants. However, considering only the food availability and access measures do not fully address the actual food energy utilization by the households and the quality of the food consumed. In addition, the drawback of relying on seven day recall method is that as a part of developing countries the majority of rural households have weak access to formal education due to that they cannot accurately respond on the types and quantities of food items consumed. The novelty of this study is that it considered households’ food consumption/utilization for seven consecutive days collected using weighed records method as food energy intake is sensitive to different unforeseen factors such as religion, weather, holidays, etc., which can be captured by taking weighted data..

The rest of the paper is organized as follows: section 2 provides the methodology employed; section 3 presents and discusses the results; and section 4 concludes and infers policy implications..

Methodology

The study area

Assosa zone, the study area, is one of the three administrative zones in Benishangul-Gumuz region of western Ethiopia. Administratively, the study area is divided into seven districts, namely; Assosa, Homosha, Bambasi, Menge, Kurmuk, Sherkole and Odabildi-Guli districts. The zone has a total population of 283,707 people, out of which 144,616 and 139,091 are male and female, respectively. Furthermore, 86.28% of the population lives in rural area and 13.72% lives in urban area. The population density of the study area is 28 persons per kilometer square (BGRDGA (Benishangul Gumuz Region Development Gap Assessment) 2010). Mixed farming (crop production and livestock rearing) system is the main sources of livelihood for the majority of the population in the area. Crop production is dominated by rain fed agriculture while irrigation is practiced on small scale level. The major livestock reared in the area are cattle, donkey, goats, sheep and poultry (AZBARD (Assosa Zone Agriculture and Rural Development Office) 2015).

Sampling technique and sample size

The study employed three-stage random sampling method to select sample households. In the first stage, out of 7 districts in Assosa zone, three districts (namely Assosa, Bambasi and Sherkole) were randomly selected. In the second stage, a total of 12 peasant associations (PAs) were randomly selected using probability proportional to the number of PAs in each sampled districts. The reason for selecting PAs was that, in the study area almost all the households relied on agriculture and the emphasis of this study was on assessing the extent of food insecurity of households working on agriculture and their coping mechanisms. In the third stage, a total of 276 sample household heads were randomly selected based on probability proportional to size of the households in the selected PAs. The sample size for this study was determined by using Yamane formula (Yamane 1967).

$$ n=\frac{\mathrm{N}}{1+\mathrm{N}{(e)}^2}=\frac{40530}{1+\left(40530x{0.06}^2\right)}=276 $$
(1)

Where n = designates the sample size, N = designates total number of estimated household heads in the study area (40530) and e = designates maximum variability or margin of error (6%).

Data set and collection methods

For this study, primary data collected from sample households using interview schedule through the enumerators and the researchers was used. Particularly, primary data on the types and quantities of every food item consumed by the household head and his/her family members was collected using Weighed records method for 7 consecutive days from each sampled households. The reason for collecting the data from a single household for seven consecutive days was that food security is a sensitive issue that is affected by different unforeseen factors (religious, holidays, etc.) which can be captured by taking weighed data (Muche and Esubalew 2015). In addition to this, primary data on household’s socio-demographic and socio-economic factors as well as on households’ food insecurity and shortage coping mechanisms was obtained through interview schedule. Besides, focus group discussions and key informants interview were also employed to supplement the research finding with qualitative information.

Method of data analysis

To analyze the collected data, the study employed descriptive statistics, food insecurity index and Tobit model. Descriptive statistics such as mean, percentage and frequency were used to describe households’ food kilocalorie intake status and to explore the coping mechanisms to food insecurity in the study area. Furthermore, the study used Foster, Greer and Thorbecke (FGT) food insecurity index in the computation of the incidence, depth and severity of food insecurity. This model is widely applicable in poverty analysis. It is a class of additively decomposable measure of poverty and food insecurity. Foster and Shorrocks (1991, 1988) branded the decomposable components of FGT measures as consistent poverty indices and argued that they make analysis of the poverty dominance easier. Particularly in food security analysis, the model is essential in analyzing the sources of change in food insecurity due to changes in the components i.e. to know the change in food insecurity is due to the incidence, or increasing deprivation of the food insecure, or because of kilocalorie short-fall below the food security line have become more unequal, or some combination of the above. Thus, in this study the model enables to estimate the three food insecurity indicators, namely the number of households below the food security line (headcount), the extent of the short-fall of the kilocalorie of the food insecure from the food security line (food insecurity gap) and the exact pattern of distribution of the kilocalorie of the food insecure households (squared food insecurity gap). Accordingly, the Foster et al. (1984) measure used in estimation of food insecurity index components is given as:

$$ \mathrm{FGT}\left(\upalpha \right)=\left(1/\mathrm{n}\right){\sum}_{\mathrm{i}=1}^{\mathrm{q}}{\left[\left(\mathrm{c}-\mathrm{yi}\right)/\mathrm{c}\right]}^{\upalpha} $$
(2)

Where: FGT (α) is the FGT food insecurity index; n is the number of sample households; yi is the measure of per adult equivalent food kilocalorie intake of the ith household; c represents the cut off between food security and food insecurity households (expressed here in terms of caloric requirements of 2100 kcal*); q is the number of food-insecure households; and α is the weight attached to the severity of food insecurity. Regarding estimation of the model, when the weight attached to α = 0 the measure is simply the headcount ratio (incidence); when α = 1 the measure is food insecurity gap (depth of food insecurity); and when α = 2 the measure is squared food insecurity gap (severity of food insecurity).

Moreover, Tobit model was estimated to analyze determinants of extent of households’ food insecurity in the study area. Studies confirmed that, when a particular dependent variable assumes some constant value for some observations and a continuous value for the rest observations, the appropriate model will be a Tobit model developed by Tobin (1958) (Wooldridge 2002; Sisay and Edriss 2013; Agyeman et al. 2014; Bukenya 2017). Tobit is an extension of the probit model and it is one approach to deal with the problem of censored data (Johnston and Dinardo 1997). Thus, in this study the dependent variable was a censored variable in which it assumed a constant or threshold value of 2100 kcal/AE/day* for food secure households and the actual food energy intake in kilocalorie for food insecure households. Suppose, however, that Yi is observed if the latent variable Yi* < 2100 kcal and is not observed if Yi* > 2100 kcal. Then the observed Yi will be defined as:

$$ Yi=\left\{\kern0.75em \begin{array}{c}{Yi}^{\ast }=\beta Xi+ Ui\kern3.75em if\ {Yi}^{\ast }<2100\ kcal\kern1em \\ {}2100\ kcal\kern6em if\ {Yi}^{\ast}\ge 2100\ kcal\kern1em \end{array}\right. $$
(3)

Where: Yi* is the latent (unobserved) variable, Yi is the observed variable, Xi is vector of explanatory variables, Ui is a vector of error terms and β is a vector of parameters to be estimated.

*Note that 2100 kcal/AE/day is the threshold value of food security stated by FDRE (1996).

Operational definition of variables in the study

Extent of food insecurity

It is a limited dependent variable, taking the threshold value (2100 kcal) if the total food energy intake is greater than or equal to the threshold value and assumed the actual food energy intake for those households whose energy intake level is less than the threshold value. The quantity of food items consumed was converted to gram and the caloric content was estimated by using the nutrient composition table of commonly eaten foods in Ethiopia. Moreover, the estimated food energy was converted into adult equivalent and reached at figure of food calorie in kilo calorie/day/AE. Accordingly, household food calorie intake per day per adult equivalent (HFCi) was measured as:

$$ \mathrm{HFCi}=\frac{\mathrm{Total}\ \mathrm{calorie}\ \mathrm{consumed}\ \mathrm{by}\ \mathrm{a}\ \mathrm{household}}{\mathrm{Household}\ \mathrm{size}\ \mathrm{in}\ \mathrm{Adult}\ \mathrm{equivalent}\ast 7} $$

Nature of settlement of the household heads

This is a dummy variable used to indicate origin of household’s. The variable took the value of 1 if respondents were settlers and 0 if natives. As depicted in Asfir (2016), unlike settlers, native households in the study area were highly resistant to accept new technologies. However, studies argued that adoption of new technologies improves agricultural production and productivity (Tsegaye and Bekele 2012) which in turn reduces households’ exposure to incidence of food shortage and insecurity. In this study, this variable was hypothesized to affect extent of households’ food insecurity negatively.

Sex of head of household

It is a dummy variable taking the value 1 if the sex of household is male and 0, otherwise. As to Baten and Khan (2010) finding, female-headed households can find it difficult than men to gain access to valuable resource, which helps them to improve production and gain more income, this in turn increases their probability of being food insecure. Thus, in this study, it was expected to affect extent of households’ food insecurity negatively.

Age of head of household

It is a continuous variable measured in years. Many studies argued that young households’ heads are stronger and energetic than elderly households as they are expected to cultivate larger-size farm and obtain high yield (Abafita and Kim, 2014; Babatunde 2007). Hence, in this study age of the household head was expected to affect extent of food insecurity negatively.

Educational level of head of household

It is a continuous variable measured in years of schooling of the household head. Education, which is a social capital, has a positive impact on household ability to take good and well-informed production and nutritional status (Babatunde 2007). Besides, Amaza et al. (2006) argued that households with higher years of schooling are less likely to be food insecure as it enables them to produce more and consume more. Thus, higher years of schooling was expected to affect extent of food insecurity negatively.

Family size

It is a continuous variable which refers to the number of family members of the household. Studies argued that larger family size tends to exert more pressure on households consumption than the labor it contributes to production (Stephen and Samuel 2013; Muche et al. 2014). Therefore, in this study, larger household size was expected to affect extent food insecurity positively.

Dependency ratio

It refers to the proportion of economically inactive labor force (less than 15 and above 65 years old) to the active labor force (between 15 and 65 years old (Velasco 2003). Due to scarcity of resources, higher dependency ratio imposes burden on the active and inactive member of household to fulfill their immediate food demands (Muche et al. 2014). Besides, higher dependency ratio indicates that the labor force is small, with a constraint on the household per capita income and consumption, which also influences the wellbeing of the household members (Nugusse et al. 2013). In this study, it was expected to positively affect extent of households’ food insecurity.

Livestock ownership (excluding oxen and donkey)

It is a continuous variable measured by the number of Tropical Livestock Unit (TLU). Livestock are important source of food and income for rural households. Households with more livestock produce more milk, milk products and meat for direct consumption. Besides, livestock enable the farm households to have better chance to earn more income from selling livestock and livestock products which assist them to purchase stable food during food shortage and invest in purchasing of farm inputs that increase food production, and ensure household food security (Mitiku et al. 2012; Gemechu et al. 2015). Livestock possession mitigates vulnerability of households during crop failures and other calamities (Abafita and Kim, 2014). Thus, this study hypothesized that owning more TLU of livestock was expected to have negative effect on the extent of food insecurity of households.

Number of oxen and donkey owned

It is a continuous variable measured in numbers owned. Oxen and donkey serve as a source of traction power in many developing countries, thereby significantly affecting household’s crop production. Animal traction power enables households to cultivate their land; others land through renting, share cropping, and execute agricultural operations timely that will enhance households access to food items (Muche et al. 2014). Accordingly, in this study more number of oxen and donkeys owned by a household was expected to affect the extent of food insecurity negatively.

Cultivated land size

It is a continuous variable which refers to the total land cultivated by a household in the past one year production period. A larger size of cultivated land implies more production and availability of food grains (Mitiku et al. 2012). Therefore, higher production and the increased availability of grains produced help to insure food security status of households (Asmelash 2015). Hence, the size of cultivated land was expected to have negative impact on extent of food insecurity.

Access to irrigation

It is a dummy variable taking the value 1 if the farmers have access to irrigation and 0, otherwise. Irrigation, as one of the technology options available, enables smallholder farmers to directly produce consumable food grains and/or diversify their cropping and supplement moisture deficiency in agriculture so that it helps to increase production and food consumption (Van der Veen and Tagel 2011). Thus, in this study, it was expected to have negative impact on extent of households’ food insecurity.

Farm income

This is a continuous variable which measures the amount of income obtained from crop production and livestock rearing measured in US Dollar. According to Beyene and Muche (2010) finding, higher farm income earning enables farmers to purchase different nutritious food items to satisfy their family food demand. Thus, for this study, farm income was hypothesized to affect extent of households’ food insecurity negatively.

Off/non-farm income

It is a continuous variable which measures the amount of cash income obtained by any household member from off-farm and non-farm activities measured in US Dollar. Studies argued that households with higher off-farm and non-farm income are less likely to be food insecure as it enables them to purchase different food items to satisfy their family needs (Beyene & Muche, 2010; Abafita and Kim 2014). Thus, off/non-farm income was expected to affect extent of food insecurity negatively.

Cost of inputs

It is a continuous variable measured in US Dollar by converting the amount of the agricultural inputs used (such as fertilizers, seeds, pesticides, chemicals, and other agricultural implements.) into monetary value based on their market price. Investing higher amount of money on farm inputs helps farmers to increase their crop production and livestock breeding (Arene and Anyaeji, 2010). In this study, it was expected to affect extent of households’ food insecurity negatively.

Access to training

It is a dummy variable that takes value 1 if a household gets access to agricultural related training and 0, otherwise. Formal agricultural training on modern technologies (proper types and rates of fertilizer application, improved varieties of seeds, agro-chemicals, etc.) helps farmers to get better production, and then this most likely leads to obtain more income to fulfill their family requirements by enhancing their agricultural production skills, knowledge and experiences (Yishak et al., 2014). Therefore, in this study, it was expected to affect extent of households’ food insecurity negatively.

Frequency of extension contact

It is a continuous variable measured in number of visits by extension agent per year. More frequent extension contact enhances households’ access to better crop production techniques, improved input as well as other production incentives, and thishelps to improve food energy intake status of households (Hussein and Janekarnkij 2013; Nugusse et al. 2013). Accordingly, in this study more number of extension contacts were expected to affect extent of households’ food insecurity negatively.

Access to credit

It is a dummy variable, which takes the value 1 if the household had access to credit and 0 otherwise. Availability of credit eases the cash constraints and allows farmers to purchase inputs such as fertilizer, improved crop varieties, and irrigation facilities; which in turn enhance food production and ultimately increase household food energy intake (Stephen and Samuel 2013). In this study, it was expected to affect extent of households’ food insecurity negatively.

Remittance and aid

It is a dummy variable, which takes the value 1 if the household had access to remittance and aid in the past one year and 0 otherwise. Both remittance and aid,from governmental and non-governmental organizations are important to smooth consumption in the case of shock and shortage for the time of emergency (Okyere et al. 2013; Mesfin 2014). Thus, for this study, it was expected to negatively affect extent of households’ food insecurity.

Distance to market

it is a continuous variable measured in kilometer (km). Proximity to the market may create opportunity of more income by providing off/non- farm employment opportunities, which determine income level of rural households. In addition, the closer the farmer is to the market the more likely the farmer gets valuable information, purchase agricultural inputs and final products required for family consumption. Therefore, this variable was expected to positively determine households’ extent of food insecurity.

Results and discussion

Socio-demographic characteristics of households

For this study, a primary data collected from a total of 276 sampled household heads was used. From the total samples, 89.13% of household heads were male and the rest 10.87% were female, and this figure indicates that male headed households were owners of major livelihood assets as usual. In addition, 43.84% of the sampled household heads were settlers and the rest (56.16%) were natives, and it shows that more than half of the samples were drawn from natives. Regarding the marital status of the households, the majority (85.5%) of the households were married households followed by divorced (6.89%), widowed (4.34%) and single (3.27%) households. Furthermore, the age distribution of the households range from 23 to 78 years and the majorities were in 30–40 year age group (47.83%) and the least were in the age group of below 30 years (5.79%). Moreover, the majority (58.33%) of the respondents had a family member falling between 5 and 10 members group followed by < 5 member group (37.67%) and > 10 member group (4%). As to households’ literacy status, the study indicated that 46.38% of the respondents had access to formal education (Table 1).

The finding of the study also figured out that the majority (74.28%) of the households were relying on combining crop and livestock production as an economic activity followed by crop production alone (21.74%) and livestock production (3.98%). In addition, it showed that 56.16% of the sampled households had access to irrigation, indicating that in the study area more than half of the samples were beneficiaries of the irrigation water. Regarding the income earning from farming activities, 44.93% of the households were earning less than 117.65 USD followed by 117.65–235.29 USDincome group (16.3%), 235.29–411.76 USD income group (15.94%), 411.76–764.71 USD income group (12.68%) and greater than 764.71 USD (10.15%). Besides, the majority (62.68%) of the households was not engaged in any type of off-farm and non-farm activities and the rest (37.32%) were earning a positive income from off-farm and non-farm activities. From the total households, 36.96% cultivated a land size of ≤0.5 ha followed by between 0.5 -1 ha (33.70%), > 1 ha (25.36%) and 0 ha (3.98%). Furthermore, the study finding showed that 80.79% of the sampled households had no access to credit service in the study area, implying that the majority of the households did not recieve any type of credit from formal and informal sources. As to households access to remittance and aid, only 5.07% of the households had obtained remittance and aid from different sources. Moreover, 47.83% of households market distance from their residence was less than 5 km followed by distance falling between 5 and 10 km (26.45%) and greater than 10 km (25.72%) (Table 1).

Households food security and energy intake in the study area

In this study, data on the type and quantity of food items consumed by the household for seven consecutive days were collected using weighed records method, and it was converted to kilocalorie and then divided to household size measured in AE and number of days. Following this, the amount of energy utilized in kilocalorie by the household was compared with the minimum subsistence requirement per adult per day (i.e. 2100 kcal). Accordingly, households in the study area were mainly consuming food items of maize products (such as white porridge, white bread, ‘injera’, and whole roasted, white’ kitaa’), wheat products (such as bread and ‘kitaa’), and teff products (such as ‘injera’ and porriage). Besides, vegetables such as onion, cabbage, tomato, and green pepper as well as livestock and poultry products such as milk, meat, egg, cheese and butter were also consumed by the households. Moreover, the locally known food item called ‘kenkes’ and oil seed products were among the food items consumed by the households. After conversion of the food items consumed to kcal/AE/day, the result of the study revealed that 148 (53.62%) of the sampled households were found to be food insecure and 128 (46.38%) of the sampled households were food secure (Table 2). This implied that more than half of the households in the study area were food insecure. Regarding the food insecurity status within each district, it is found that 58.04% of households in Assosa district were food insecure. This indicates, in the district, the incidence of food insecurity was higher i.e. there were more number of food insecure households as compared to the food secure ones and it was mainly attributed to the incidence of pest outbreak in the 2016/17 production season which led to loss of thousands of quintals of crop production in the district. Furthermore, the study revealed that 48.89% and 48.84% of the households were food insecure in Bambasi and Sherkole districts, respectively (Table 2). Though more than half of the households were food secure, the state of food insecurity was high in both districts. Generally, the incidence of food insecurity was relatively higher in Assosa district as compared to the other two districts.

Moreover, the study finding indicated that the mean calorie intake of the sampled households was 1991.42 kcal per adult equivalent per day, which was lower than the minimum calorie requirement of 2100 kcal for a healthy and productive life, with maximum and minimum level of kilocalorie energy intake being 4286.91 and 597.65, respectively. Besides, the calorie intake of food insecure households ranges from 597.65 kcal and 2048.13 kcal with mean kilocalorie energy intake of 1440.37. The finding also revealed that the mean energy intake of food secure households was 2628.56 kcal per adult equivalent per day with the maximum and minimum energy intakes being 4286.91 and 2116.67 kcal per adult equivalent per day, respectively (Table 3).

Households extent of food insecurity in the study area

FGT food insecurity index was used to assess the extent of food insecurity in the study area. Thus, the finding of head count ratio from food insecurity index indicated that the incidence of food insecurity was 53.62%, and it indicated that 53.62% of the households were actually in the state of food insecurity, that is, unable to get the minimum recommended calorie for subsistence. The food insecurity gap, which is a measure of depth of food insecurity, pointed out that each food insecure household needed 16.84% of the daily caloric requirement to bring them up to the recommended daily caloric requirement level. This means, on average, the households need to be supplied with 16.84% of the daily minimum calorie requirement to get out of the food insecurity problem. The average extent of the calorie deficiency gap for the sampled households was, therefore, 353.64Kcal/AE/day; which means, on average 353.64Kcal/AE/day of additional food energy would be needed to lift the households out of food insecurity, then at least in theory, food insecurity could be eliminated. Moreover, the result of squared food insecurity gap from food insecurity index figured out that the severity of food insecurity in the study area was 7.32% (Table 4).

Determinants of the extent of households food insecurity in the study area

Tobit model was estimated to analyze the determinants of the extent of households’ food insecurity. Accordingly, results from the Tobit model using data obtained from 276 sample households (of which 128 were censored/food secure according to the model result) are presented in Table 5. The overall model is significant at 1% as indicated by the likelihood ratio test (Prob > χ2 = 0.0001). In addition, the model estimate revealed that out of the 18 explanatory variables, 7 variables were found to have a significant impact on households’ extent of food insecurity. Thus, only statistically significant variables at less than 10% probability levels were discussed.

Age of the household head

As expected, it affected household’s level of energy intake negatively (extent of food insecurity positively) and significantly at 5% significance level in the study area. The marginal effect, from of the model result, indicated that a one year increase in the age, within food insecure households, increased the likelihood of household’s extent of food insecurity by 448%. This implies that old aged household heads within food insecure households were more likely to face higher degree of energy intake deficiency than younger ones. This is because as age increases households become less productive and have less courage to cultivate larger-size farm than young ones. In addition, mostly elder households have large number of families and their resources are distributed among the members, and this imposes pressure on their income to purchase consumable products. This finding is in line with the finding of Bukenya (2017).

Family size

As expected, this variable negatively and significantly affected households’ intensity of energy intake at 10% significance level. From the model output, the marginal effect revealed that one extra person in the household increased the probability of household’s intensity of food energy intake deficiency by 1211%. This indicates that households with larger family size tend to be more food energy deficient than households with smaller family size in the study area. This is due to the reason that, households with large family size could be composed of large number of non-productive members; which imposes high burden on the labor force and food available to each person and ultimately end up with difficulty to achieve food security. This finding supports the finding of Stephen and Samuel (2013).

Access to irrigation

It affected households’ extent of food energy intake positively (extent of food insecurity negatively) and significantly at 10% significance level. From the model result, the marginal effect showed that having access to irrigation increased food insecure households’ likelihood of the extent of food energy intake by 7098%. This implies that households who had irrigation access were less likely to be food energy deficient than those who had no irrigation access, and the result supports the finding of Van der Veen and Tagel (2011). This is due to the fact that, access to irrigation helps households’ to produce more than once in a year through mitigating water stress and reducing risks of crop failures and obtains more yields; thereby reducing the extent of food insecurity among the households.

Total farm income

As expected, it determined households’ extent of food energy intake positively (extent of food insecurity negatively) and significantly at 5% significance level. From the model output, the marginal effect pointed out that a one birr (0.0588 USD) increase in farm income, within food insecure households, decreased the probability of their energy intake deficiency by 0.76%. This indicates that higher farm income earning households were less likely to energy deficient than low farm income earning households in the study area. This is because higher farm income helps the farmers to purchase diversified and nutritious food items which in turn helps them to improve their food energy intake status (Bukenya 2017; Mitiku et al. 2012).

Off-farm and non-farm income

In contrary to the expectation, it negatively and significantly affected households’ extent of energy intake at 5% significance level. From the model result, the marginal effect confirmed that a one birr (0.0588 USD) increase in the off-farm and non-farm income increased the probability of food insecure households’ food energy intake deficiency by 1.02%. This indicates that food insecure households with higher off-farm and non-farm income earning were more likely to be food energy deficient than low earning households in the study area. This is because, in the study area, households engaged in off-farm and non-farm income earning activities focus on accumulating physical and financial resources to improve their future wellbeing than spending their income on purchasing food products to satisfy their current food requirement, and this result supports the finding of Indris (2012).

Access to credit

As expected, it affected households’ extent of energy intake positively and significantly at 1% significance level. The marginal effect, from the model result, showed that having access to credit decreased food insecure household’s probability of food energy deficiency by 13,921%. This implies households who had access to credit service had less chance to be food energy deficient as compared to those who had no access to credit. This is due to the reason that, in the study area, households were receiving credit mainly in kind such as in the form of fertilizer, seed, herbicide, etc., from agricultural offices, and it enabled them to use their income in purchasing diverse and nutritious food items rather than various types of inputs to reduce the risk of high degree of food insecurity. Stephen and Samuel (2013) also reported similar finding.

Distance to market

As expected, this variable affected extent of household’s food insecurity negatively and significantly at 5% probability level in the study area. From the model output, the marginal effect indicated that a one kilometer increase in the residence of households from the nearest market decreased the probability of food energy deficiency by 818%. This implies that food insecure households living near the market center were more likely to be energy deficient than those living far from the market center. This is because, in the study area, households living far from the market center were mainly producing consumable product items as compared to those households living close to market center who were producing cash crops.

Households coping mechanisms to food insecurity and shortage in the study area

Studies conducted in Ethiopia argued that households adopt a range of coping mechanisms during food insecurity and/or food shortage (Sewnet 2015; Arega 2015). The results of the study confirmed that households in the study area adopted diversified coping mechanisms at times of food shortage and/or food insecurity. Accordingly, 81.9% of the sampled households pursued reducing frequency of meal as a coping mechanism, followed by reducing the size of meal served (78.6%) and working as a daily laborer (68.1%). This implies that the majority of the households were adopting decreasing the number of meal serving time, size of meal and working as daily laborer as their coping mechanism to cope up with the risks of food shortage and/or food insecurity. Furthermore, the study also pointed out that 49.3, 48.6, 43.5, 37.7, 37.7, 35.9, 32.2, 29.7 and 5.07% of the sampled households were using sale fire wood and charcoal, engaging in wild fruit gathering, engaging in petty trade, selling livestock’s, borrowing/loan, selling different assets, mining, migrating to cities and remittance and food aid, respectively, as coping mechanisms against food shortage and food insecurity in the study area (Table 6).

Moreover, the study result revealed that reducing meal size was the most effective and most important coping mechanism used by the large segment of the households (36.6%), followed by reducing frequency of meal (27.9%) and working as a daily laborer (13.77%). In addition, the finding of the study showed that 11.23, 2.9, 2.9, 2.17, 1.09, 0.72, 0.36 and 0.36% of the sampled households adopted selling livestock’s, remittance and food aid, migration, wild fruit gathering, selling wood and charcoal, receiving loan, selling different assets and engaging petty trade, respectively, as their most effective and important coping mechanisms against food shortage and food insecurity (Table 7). This finding supports the findings of Sewnet (2015), Birara et al. (2015) and Woldeamanuel (2009) which concluded that rural households pursued various coping mechanisms when food crisis hits them so as to reduce the risk associated with food insecurity.

Conclusions and recommendations

Food insecurity and poverty are critical and persistent problems facing most Ethiopians today. In an effort to reverse the incidence of these problems, different studies recommended that improving the livelihood of the rural poor plays a key role. The improvement programs in the welfare of rural community to be effective, they need to be supported by empirical evidences that provide important input on households’ food security for concerned bodies. Thus, this study assessed households’ extent of food insecurity and its determinants along with the coping mechanisms opted against food insecurity and shortage in Assosa zone using a data collected from 276 sample households.

Accordingly, the findings of the study pointed out that the incidence of food insecurity (53.62%) was high in the study area, with the depth and severity of food insecurity being 16.84% and 7.32%, respectively. This implies that more than half of the households in the study area were food insecure. In addition, the estimated Tobit model results revealed that farm income, access to irrigation, access to credit and distance to market negatively affected the extent of households’ food insecurity; whereas age of the household head, family size and off-farm and non-farm income positively affected households extent of food insecurity. To cope up with the food insecurity and shortage situation, households opted reducing frequency of meal, reducing the size of meal served, working as a daily laborer, selling fire wood and charcoal, engaging in wild fruit gathering and petty trade as top six coping mechanisms in the study area.

Thus, urgent actions directed towards reducing and/or eliminating rural households’ food insecurity in the study area should focus on:

  • Awareness creation on effective family planning and the impact of large family size on ensuring food security, and awareness creation and capacity building for elder households through ensuring the availability and dissemination of accurate information should be strengthened.

  • Enhancing rural household’s access to credit as it enables them to purchase different inputs to improve their production and consumable products and thereby helps them to reduce and/or eliminate food insecurity and improve their wellbeing.

  • Construction of irrigation schemes as access to irrigation enables households to produce more than once in a year through reducing water stress and the risk of crop failure and thereby helps them to reduce and/or eliminate food insecurity.

  • Enhancing household’s farm income-earning opportunities through provision of sufficient input to enhance agricultural production and productivity; and improving households’ technical skill as well as their awareness on utilization of the off-farm and non-farm income to improve households’ food security situation.

  • Even though, better access to markets assumed to reduce transport and other market related transaction costs, the study finding indicated the opposite. Therefore, enhancing households’ awareness about the importance of better access to markets on their informed decision regarding their choice of output to be produced and products to be purchased in the market that helps the households to enhance their food security status in the near future.

  • Generally, as a policy implication the government should exhaustively work on promoting irrigation, facilitating credit availability and subsidize the farmers to reverse the problem of food insecurity and to enhance households coping capacity to food shortage and/or insecurity. Besides, this study has attempted to come up with the result of the analysis with defined scope however a lot remained to be unanswered. To provide basic information on the determinants of food security and extent of food insecurity, the social, political, natural and environmental dimensions, descriptive data on purchasing patterns of food insecure, specific characteristics that make rural poor more vulnerable to food insecurity demands future researchers’ attention.
