Literature Review: Influence of Food and Nutrition Security on the Health of Refugees in Kakuma Refugee Camp and Kalobeyei Settlement, Kenya

1. Introduction

Food and nutrition security is a core determinant of health outcomes for refugees, especially in protracted camp settings such as Kakuma Refugee Camp and Kalobeyei Settlement in northwest Kenya. The relationship between food security and health is particularly complex in refugee environments due to dependency on humanitarian assistance, local ecological constraints, limited access to livelihoods, and intersecting vulnerabilities based on gender, age, and disability. The case of Kakuma and Kalobeyei is illustrative of many of these broader dynamics, as well as emerging policy innovations intended to foster self-reliance among refugees[1].

2. Food and Nutrition Security: Definitions and Interventions

Food security among refugees encompasses consistent physical, social, and economic access to sufficient, safe, and nutritious food to meet dietary needs and preferences for an active life. Interventions to address food insecurity in refugee settings have primarily included in-kind food distributions, cash/voucher systems, nutritional education, and efforts to promote urban agriculture or small-scale farming[2][1]. In both Kakuma and Kalobeyei, cash and voucher transfers have become more prominent, particularly in Kalobeyei, coupled with small-scale agriculture and nutrition education; however, implementation varies and challenges persist around measurement and sustained impact[2][1].

A crucial gap consistently identified is the lack of harmonization in how food security is assessed, with only 39% of research interventions directly measuring food security. Furthermore, gender-sensitive implementation of food security interventions remains inadequate, despite being recognized as essential in planning stages[2].

3. Context: Kakuma and Kalobeyei

Kakuma Refugee Camp, established in 1992, has grown to accommodate hundreds of thousands of refugees from neighboring conflict-affected regions. In contrast, Kalobeyei Settlement, introduced in 2016, was envisioned as an innovative model for refugee self-reliance, encouraging market-based aid (notably increased cash assistance) and integration with host communities[1]. Despite policy differences, structural factors—such as the arid environment, limited economic opportunities, and dependence on humanitarian systems—mean that enabling conditions for self-reliance remain remarkably similar between the two sites[1].

4. Food and Nutrition Insecurity: Prevalence and Health Consequences

Numerous studies highlight that food insecurity is highly prevalent among refugees globally, with up to 80% of this population lacking reliable access to adequate nutrition[2]. In Kenya’s refugee camps, this manifests as household food shortages, reduced dietary diversity, and limited intake of animal-source foods and micronutrients. Adolescent refugees in Kakuma demonstrate strikingly high rates of anaemia (46%) and iron deficiency (43%), alongside notable vitamin A deficiency (15%)[3]. Such micronutrient deficiencies are associated with increased developmental risks and heightened vulnerability to disease.

More recent intervention studies in Kakuma show only modest improvements in iron status among women and children from micronutrient powder supplementation, with prevalence of anaemia remaining stubbornly high and with no significant observed improvement in hemoglobin levels among recipients[4]. This underscores the difficulty of addressing entrenched nutritional deficiencies solely through periodic supplementation in the absence of wider improvements in dietary diversity and food quality.

5. Influence of Aid Models: Cash Assistance and Self-Reliance

Kalobeyei’s cash-assisted, self-reliance–oriented model is distinct from Kakuma's more traditional aid-dependent approach[1]. In Kalobeyei, refugees report greater perceived autonomy over food choices and modest improvements in short-term nutritional outcomes, possibly due to the flexibility of cash transfers[1]. Nonetheless, even with these differences, fundamental self-reliance–enabling assets—such as stable economic opportunities, fertile land, and robust market access—remain similarly constrained across both sites, limiting transformative shifts in food security for the majority of residents[1].

6. Gender, Food Security, and Health

Gender considerations are central to understanding food security and its health impacts in these camps. Women and adolescent girls face disproportionate burdens related to both food insecurity and associated health consequences[2][3]. Qualitative studies illuminate that women’s coping strategies are circumscribed by basic survival needs, with formal support from agencies like UNHCR being their primary resource, and limited informal support due to social fragmentation[5]. Reports from Kakuma indicate elevated physical and psychological insecurity for women, including insecurity in healthcare access, which further constrains their ability to secure adequate food and nutrition for themselves and their children[6].

Despite this, food security interventions often fail to incorporate gender-sensitive implementation or to address the unique risks women face, such as gender-based discrimination in intra-household food allocation or exposure to violence during food procurement activities[2][6].

7. Coping Strategies and Mental Health

Food insecurity provokes a range of coping mechanisms among refugee households, notably reducing meal frequency, prioritizing children over adults for available food, or relying on food-sharing networks when possible[5]. Other evidence demonstrates that chronic food insecurity and the stress associated with unmet basic needs negatively impact mental health, especially among women[6][5]. These psychosocial consequences are often magnified by the general insecurity and unpredictability of life in the camps[6].

8. Special Populations: Adolescents and Disabled Persons

Adolescents in camps are highly susceptible to nutritional deficiencies such as anemia and vitamin A deficiency due to both physiological and programmatic factors, including insufficient programmatic targeting by health and nutrition programs[3]. Additionally, people with disabilities in Kakuma are at greater risk of diarrheal diseases and associated nutritional losses due to poor sanitation infrastructure and inadequate adaptations in public health facilities[7].

9. Positive Host-Community Effects

Interestingly, research indicates that the presence of refugee camps, while often assumed to generate resource competition, can also positively impact nutritional status in host communities, possibly through increased access to markets, economic resources, and improved infrastructure associated with humanitarian interventions[8]. This highlights the potential for integrated programming to deliver benefits beyond the refugee population.

10. Intervention Gaps and Future Research Directions

Key challenges persist in intervention design and evaluation. There is a need for:

• Consistent measurement tools for food security to enable robust evaluation of interventions and comparisons across sites[2].
• Greater collaboration among aid agencies to harness synergies in program delivery[2].
• Systematic inclusion of gender and disability considerations in program implementation and monitoring[2][6][7].
• Evidence generation regarding medium- and long-term health impacts of cash-based versus in-kind assistance, particularly regarding nutritional status and self-reliance outcomes[1].
• Targeted research on adolescent nutritional needs and effective ways to reach this group in the camp context[3].

11. Conclusion

The influence of food and nutrition security on the health of refugees in Kakuma and Kalobeyei is profound and multifaceted. Despite innovation in aid models and attempts to foster self-reliance, entrenched vulnerabilities linked to gender, age, and disability, combined with persistent limitations in the local environment and humanitarian systems, continue to shape health risks in both camps. Advancing refugee health will require multi-sectoral approaches that link food assistance to broader livelihood, protection, and health initiatives—with rigorous evaluation, gender sensitivity, and sustained investment at their core[2][1][8][3][6][4][5][7].
