Gendered determinants of food insecurity in ongoing regional conflicts, North and South Kivu, the Democratic Republic of Congo

Abstract

Background

Food insecurity remains a major concern worldwide. In North and South Kivu provinces, the Democratic Republic of the Congo, repeated wars and gender-based violence exacerbate the situation. However, little is known about the determinants of food insecurity in the region.

Objective

This study analyzed the gendered determinants of food insecurity in North and South Kivu in the Democratic Republic of Congo, a region of ongoing civil conflict.

Methods

1754 women were included in a cross-sectional study. Multilevel ordinal logistic regression was used to identify household-level determinants of food insecurity.

Results

The poorest households were five times more likely to be food insecure (OR = 5.66, 95% CI 3.74–8.55). Women’s participation in decision-making about resource allocation decreased the risk for household food insecurity (OR = 0.68, 95% CI 0.57–0.87), while higher tolerance to gender-based violence increased the risk of food insecurity (OR = 1.29, 95% CI 1.05–1.54).

Conclusion

Involving empowered women in decision-making about resource allocation and actions to reduce gender-based violence could help mitigate food insecurity.

Background

Worldwide, food insecurity is a major concern: over 820 million people are estimated to suffer from hunger which translates to one in nine persons globally [1]. Food insecurity is a social as well as a biological, nutritional, and economic phenomenon [2]. Food security is achieved when all people in the household, at all times, have physical, social, and economic access to sufficient, safe, and nutritious food which meets their dietary needs and food preferences for an active and healthy life [3]. Food security is about availability, stability, accessibility, and utilization: food availability is necessary but not sufficient for access, access is necessary but not sufficient for utilization, and stability is necessary but not sufficient for utilization [4].

For years, blanket strategies were implemented to achieve food security across entire world regions. Evidence demonstrates, however, that every region faces unique challenges and solutions should therefore be adapted to context [5,6,7,8]. Authors examining determinants of food insecurity found that household gender dynamics are key. In several studies, households headed by men were more likely to have a low level of food insecurity [9,10,11,12]. However, some authors postulate that differences in food insecurity lie not so much in the gender of the household head but some unobserved differences affecting the use of household resources [13]; others point to the lack of women decision-makers in the household [14, 15]. Some authors working in African contexts advocate that female heads of households will enhance household food security as women are in charge of food preparation, processing, and preservation [16, 17]. Few authors have studied other aspects of the gender power balance in decision-making, including gender-based violence and its impact on food insecurity.

One in four people in Africa faces widespread and chronic malnutrition as well as a constant threat of acute food crisis and famine [8, 18, 19]. The Democratic Republic of Congo (DRC) is one sub-Saharan country where food insecurity persists. The DRC ranks among the poorest countries in the world [20]. In 2018, approximately 13.1 million Congolese experienced acute food insecurity and livelihood crisis with 51% of the population farming [21,22,23]. The combination of persistent armed conflict, massive population displacement, poor or non-existent infrastructure, and widespread deterioration of productive assets has significantly affected food security in the DRC. With growing insecurity in rural areas due to civil wars, land is abandoned leading to urban overpopulation. Kasai, South Kivu, North Kivu, Ituri, Maniema, and Tanganyika provinces are facing population displacement which limits households' abilities to access typical livelihood activities and places many at risk for food insecurity [22, 24]. Simultaneously, gender-based violence is increasing in the Kivu region [25,26,27,28,29]. South Kivu has one of the high burdens of sexual violence in the country. According to the Demographic Health Survey (DHS), 34.5% of women were victims of sexual violence in 2014 [23].

Few studies investigating the gendered dimensions of food insecurity in ongoing conflict zones in DRC exist. The purpose of this study is to explore the determinants of household food insecurity in North and South Kivu, DRC, including decision-making and head of household gender. This analysis will help inform specific actions to be taken to address food insecurity in these and similar regions.

Method

Study setting

Data were collected as part of an evaluation of a gender empowerment project in North and South Kivu, DRC from March to December 2017. Data were collected in both rural (Walungu, South Kivu and Rusthuru, North Kivu) and urban (Goma and Karisimbi in North Kivu, and Ibanda, Bagira, and Kadutu in South Kivu) contexts.

Study design and sampling

This paper analyzes cross-sectional data from women who participated in the baseline study of the “Mawe tatu” project aimed at improving household socio-economic status through village saving and loan associations (VSLA) approach. The project Mawe tatu targeted persons of “lower” socio-economic background and selected women for participation by using community-based targeting––approaching community leaders to provide listings with vulnerable households and invite women from these households to an initial meeting––but participation in the project was voluntary. To select villages to be included in this study, cluster randomized sampling was used. The power calculation was based on the hypothesis that village saving and loan systems lower the risk of stunting in children. The sample size calculation has been described in detail elsewhere [30]. 80 villages were randomly selected for inclusion in this study, and in each village, participants were randomly selected from new VLSLAs implemented by the Mawe tatu project.

23,000 women were expected to take part in the Mawe tatu project of whom a minimum of 1200 women were to be included in the baseline study. For villages with one new VSLA, 15 women were recruited for this study. For villages with two or more new VSLAs, 25 women were recruited. Ultimately, 1754 women were enrolled in this study.

Instruments

The questionnaire included questions about household food insecurity and socio-economic variables that affect food insecurity including age, sex, gender, education level, household size, employment status, and self-rated level of household poverty compared to the surrounding community. To ensure unbiased answers on the self-rated level of household poverty, a previously validated scale was used [31]. In addition, research assistants ranked households’ wealth based on the construction of the house (mud house, mud house with an iron sheet roof, brick house). Further questions included the relation of the participants to the household head, the main breadwinner, the main household decision-maker, and attitudes toward gender-based violence and gender inequality. Scales were used to measure respondent food insecurity, attitudes toward gender-based violence, and intra-household decision-making.

Food insecurity measurement

Food insecurity was the main outcome of interest. Food insecurity was defined by the globally employed Food and Agriculture Organization's Food Insecurity Experience Scale (FIES) [3], used in previous studies on food insecurity [32, 33]. Since the dependent variable was food insecurity, the FIES was computed as a summative-scaled score with ten items (yes/no responses), categorizing household food insecurity into three levels: severe, moderate, and mild. The recall time question was of four weeks (or 30 days).

Mild food insecurity	Moderate food insecurity		Severe food insecurity
Worrying about the ability to obtain food	Compromising quality and variety of food	Reducing quantities, skipping meals	Experiencing hunger

Many authors have studied food insecurity as an ordinal categorical variable [13, 34, 35]. Due to the high prevalence of food insecurity in the study region, a summative scale was computed to assess the difference in the households according to their experience. To ensure that the model was not sensitive to outliers (robustness), percentiles were created from the FIES scale.

Decision-making and gender-based violence measurements

The items included in intra-household, summative scales measuring decision-making and tolerance of gender-based violence (GBV) were defined according to previous studies, including DHS [23, 36].

Items included the following: "Who in your household usually decides on special expenditures such as health care?" ”More specifically, who decides where to seek care for maternal and child health issues?” “Who in your household usually decides if you personally want to take a loan?” “Who in your household decides if someone in your household wants to buy or sell a mobile phone?” “ Who in your household decides regarding buying or selling land?” “ Who in your household decides how your own income is used?” “ Who in your couple decides when to have children?” “Who in your couple decides whether to use family planning?” Each item was coded 1 if the woman was participating in the household decision-making and 0 if not, then the summative scale was computed.

For the tolerance of GBV scale, nine binary items were retained based on previous studies in the region [23, 36]: (a)“It is normal that a man beats his wife if she is unfaithful”; (b)“It is normal if a parent beats a girl if she is getting pregnant outside of marriage”; (c)“It is normal if a man beats his wife if she doesn't want to have sex with him”; (d)“If someone insults a man he must defend his reputation using violence if needed”; (e)“If a person wastes money it is normal that he/she is beaten”; (f)“It is normal that a man beats his wife if she goes out without telling him”; (g)“It is normal that a man beats his wife if she argues with him”; (h)“It is normal that a man beats his wife if she neglects the children”; and (i)” It is normal that a man beats his wife if she burns the food”. Then, a summative scale was computed for each participant.

Data collection

Data were collected using tablets with the Open Data Kit software package; questions were translated into the main local language, Swahili. A team of 20 local researchers fluent in locally spoken languages was trained over a week in data collection methods, followed by a pilot study. Regular data quality checks were done using a short verification questionnaire with a randomly selected sub-sample of 30 participants right after the interview and consistent field supervision. Data were stored on a secured server accessed only by core research team members.

Data analysis

Mokken analysis is a non-parametric procedure based on item response theory and helped confirm the unidimensionality and reliability of the food insecurity, decision, and violence scales. Mokken analysis was used to assess similar scales in previous studies [37, 38]. Mokken scale analysis establishes hierarchies of items. Three basic assumptions are required: unidimensionality, local independence, and monotonicity. Scale homogeneity is based on Loevinger’s index of homogeneity H [39]. As a rule of thumb Loevinger’s coefficient H < 0.30 indicates poor scalability properties, for 0.30 < H < 0.40 the scale is weak; for 0.40 < H < 0.50 the scale is medium, and for H > 0.50 the scale is strong. The reliability of Mokken scales is estimated using Rho, which is a test–retest reliability coefficient with Rho > 0.7 considered to indicate a reliable scale [40]. The items that satisfied the three assumptions of the Mokken analysis can be added up and individual scores are then computed as the rank of the highest endorsed item in this hierarchy, i.e., it is a simple total score (sum of positive responses). This total score is used as an estimate of the level of the latent construct, in this case, decision-making, violence scale, and food insecurity in each subject.

Intra-household decision-making: All items were included in the scale using (msp average inter-item correlation: 0.46; scale reliability coefficient 0.88; Hjk 0.839).

Tolerance of gender-based violence scale: Ten items were included in the retained scale, score of reliability 0.74; average inter-item correlation 0.227; Hjk 0.776).

Bivariate binary logistic regression analysis was performed to show the crude association between food insecurity (the outcome) and the exposure variables of interest (age, education, marital status, relation to the head of the family, number of children, wealth perception, breadwinner, decision-making in the couple, and violence scale). Then a multilevel ordinal regression was used to identify determinants of household food insecurity by using the adjusted association between food insecurity and the exposure variables. In post-conflict zones, multilevel ordinal regression has been established as a robust method to study the determinants of food insecurity [34]. Mixed-effects models were used to account for the clustering design. The Hosmer–Lemeshow goodness-of-fit was used to check if the necessary assumptions for multilevel logistic regression were fulfilled. The model had a p-value > 0.05, suggesting that the model fit the data well. The AIC was used to compare different models; the model with the lowest AIC was retained. Odds ratios with 95% confidence intervals (CI) were calculated and the statistical significance was accepted at the 5% level of significance (p < 5%). Data were analyzed using Stata 15.0.

Ethical issues

Informed verbal and written consent was obtained from each individual before the beginning of data collection and all consent forms were translated into local languages.

Participation in this study was voluntary, and refusal to participate in the study had no repercussion whatsoever. Confidentiality was guaranteed. Any participant requesting help or information on a particular topic including GBV was referred to the closest health care facility. No fees were required of participants and no compensation was offered in exchange for participation in this study.

Results

Respondent and respondent household socio-demographics

1754 households were included in this study. Table 1 summarizes the socio-demographic characteristics of the households.

Table 1 Socio-demographics characteristics of respondents

The mean age of the study population was 36 ± 12 years. The majority of the study population 53.9% (n = 946) was aged between 20 and 39 years. 42.6% (n = 745) of the sample reached the secondary level at school, 76.1% (n = 1333) were married, and 70.4% (n = 1237) were living in urban areas. More than half 54.3% (n = 953) of the sample size reported they were self-employed, mostly involved in small business. 70.5% (n = 1237) of the participants lived in urban settings. The mean average of the household size was 7.5 ± 3.1 people. The mean meals per day was 1.8 ± 0.6 meals. 42.5% (n = 666) of people interviewed perceived their household to have the same wealth as the neighborhood and more than 31% (n = 486) estimated that they considered themselves somewhat poorer than others (Table 1). More than 70% (n = 1190) reported their husband or partner as the head of the household (Table 1). Most households reported having a male breadwinner.

Food insecurity

Table 2 reports household FIES with a recall period of four weeks (30 days).

Table 2 Food insecurity (FIES)

71.0% (n = 1243) went without eating for a whole day because of lack of money and other resources and 78.3% (n = 1339) participants reported that children were not given enough food to eat (Table 2). Classifying the households' food insecurity according to FIES, almost all of the study population was experiencing food insecurity, with 87.8% of the respondents experiencing severe food insecurity and only 5.5% reporting to have been food secure (Table 3).

Table 4 presents household food insecurity classes using percentiles.

Table 4 Summative scale of household food insecurity

The multilevel ordinal logistic regression assessed risk factors for food insecurity levels generated from the 10 quantiles of the summative scale. Odds ratios associated with food insecurity are presented in Table 5.

Table 5 Multilevel ordinal regression of food insecurity (using the summative food insecurity scale based on FAO/FIES scale 1–5, where 1 represents lower level of food insecurity and 5 represents higher level of food insecure)

Participants perceiving their household as “poorer” or “much poorer” were, respectively, three times and five times more likely to be food insecure (OR = 3.31, 95% CI 2.50–4.38; OR = 5.66, 95% CI 3.74–8.55, respectively). The more the woman was participating in decision-making, the less likely the household was to be food insecure (OR = 0.68, 95% CI 0.53–0.87). Higher tolerance of gender-based violence increased the risk of the household being food insecure (OR = 1.29, 95% CI 1.05–1.59). Women who were employed or self-employed were more likely to be food insecure (respectively, OR = 1.56, 95% CI 1.17–2.07 and OR = 2.26, 95% CI 1.48–3.45). Having a secondary level of education decreased the risk of the household being food insecure (OR = 0.59, 95% CI  0.40–0.87). Perceiving oneself “somewhat richer” than others and living in an urban area decreased the risk of the household being food insecure (OR = 0.35, 95% CI 0.24–0.52; OR = 0.48, 95% CI 0.32–0.71, respectively). Households headed by the husband or male partner were less likely to be food insecure (OR = 0.56, 95% CI 0.35–0.90), but the association was not statistically significant.

Discussion

Socio-demographic characteristics of the studied sample were consistent with regional socio-demographics reported in the most recent DHS survey, giving the sample credibility to be representative of the community.

The observed difference between being the head of the family and being the breadwinner is of note but has been described as the result of the high unemployment rate and the development of small activities by women to ensure the survival of the family [41, 42].

The study results indicated that food insecurity is very high in eastern DRC, which correlates with reports from FAO and other authors [22, 43, 44]. The level of food insecurity in this region is higher than what was found in Kinshasa, the capital of DRC, and in other African countries [45,46,47,48,49,50]. The ongoing conflicts in North and South Kivu may be the key explanation to this as FAO has classified the Kivu region as high-conflict zone areas [22]. More than 70% of the study population resided in urban areas; unfortunately, the level of food insecurity measured in this study was worse compared to the results from studies done in other urban areas in Africa [43, 45, 46]. However, this study reinforced what other authors highlighted about the rapid increase in urban population due to rural migration, urban food crisis, and other related factors [46, 51,52,53,54]. In the study region, many villages are deserted because of insecurity due to ongoing armed conflicts and wars. The unemployment rate, which increased with the growth of the urban population, could have worsened the situation. The surprisingly high prevalence of food insecurity in employed and self-employed people can be explained by the fact that employed people are mostly functionaries. They are underpaid and/or irregularly paid in Congolese francs, a highly unstable currency. Unfortunately, the variation in salaries does not follow the fluctuations of the currency, unlike goods on the market. The precarious socio-economic conditions in the region force employed and self-employed individuals to work hard to barely secure their livings while unemployed people can only rely on charity for their daily survival.

It was not surprising that regression also showed that wealth perception was statistically associated with household food insecurity level.

Unlike previous studies, the present results showed that men being the head of the household was not significantly associated with a lower likelihood of food insecurity [8, 9, 11, 35]. However, Kassie et al. explained that the difference between male- and female-headed households is mainly because women often do not have the same access to remunerative work in Africa and they generally do not have a level of education that can help them cope [13]. Appleton and Duflo predicted that households headed by women would be less food insecure as women are responsible for preparing food for all of the family members. Contrary to men, women devote the bulk of their earnings to household expenditures which has positive effects on other members’ welfare [55, 56]. The assumption was not verified in the present study, probably because women-headed households would be more vulnerable to extreme poverty exacerbated by the long period of conflict in the region. Others found similar results that women-headed households faced multiple challenges, such as limited access to land ownership, technology, or lack of agriculture extension services [57]. However, women and men encounter the same agricultural technology challenges in the Kivu regions.

Tolerance of GBV was significantly associated with food insecurity, which corroborates other findings [58,59,60]. However, previous studies also found that food insecurity increased gender-based violence and specifically intimate partner violence [61,62,63,64]. Fong et al. are among the few who stated that the relationship between gender-based violence and food insecurity could be bidirectional [61].

This study also found that an increased level of women's decision-making drivers downs the likelihood of food insecurity. Gendered divisions of labor generally place women in a central role in the preparation and production of food. Women’s active participation in household decision-making, supported by higher levels of formal education, can challenge prevalent socio-cultural norms which unequally distribute food between genders [65, 66].

However, further research is needed to assess if women's participation in decision-making alone or tolerance of gender-based violence is associated with food insecurity, excluding potential mediators, such as societal norms.

Strengths and limitations

The strength of this study lies in being community based with a considerable participation rate. This study is among the few studies done to assess the food insecurity in North and South Kivu in DRC with special attention to gender and household power dynamics.

In the present study, food insecurity was an experienced scale measure of the household’s ability to afford food. However, the scale did not consider other aspects that could have had a bearing on food insecurity, such as quality of food consumed, food fads, and food preference.

Conclusion

In regions with a high prevalence of food insecurity, measuring determinants of food insecurity is not easy. However, this study succeeded in contributing to the literature by highlighting several important findings. First, household wealth perception was strongly associated with food insecurity: the poorer the household, the more likely it was to be food insecure. A secondary level of education decreased the risk of food insecurity while having employment surprisingly increased the risk. Women's participation in decision-making was associated with lower levels of food insecurity. Finally, tolerance of violence was associated with higher levels of food insecurity.

More studies are needed to better understand the relationship between gendered aspects of household power dynamics and food insecurity. Cultural and societal barriers women face in the community may play an important role in the association between gender aspects and food insecurity. Further research could help better understand these associations and inform as of yet unexplored approaches to interventions to combat this prevalent regional challenge.

Policy implications

These results have policy implications for interventions aiming to fight food insecurity, especially in ongoing conflict zones. First, interventions should consider improving women's participation in household decision-making and reducing tolerance and experience of gender-based violence. This study suggests that interventions to improve food security must take into account gender dynamics in the household. For example, gender transformative approaches to empower women to express their opinions and sensitize men to reduce gender-based violence could have a positive impact on ensuring greater food security for more households. Further research on the effects of gender transformative approaches on food security outcomes would help develop more context-specific policies for implementation on local and regional levels.
