Social Network and Food Security in the Urban Fringes

This book dismantles the myth that hunger is only about food supply or household income. Using survey data, network maps, and vivid household stories from Kampala's fringes, it proves access to food is relational. Read it if you work in development, food policy, urban planning, or community programs - or if you want to understand how survival actually works where the city runs out and the village hasn't quite begun.

1. 1Chapters 1-2

   The fringe where town and country collide

   Picture the edge of Kampala, Uganda. Bwaise and Kawaala sit in that messy band where the city dissolves into farmland - the urban fringe. Land, water, and infrastructure are fought over intensely because both worlds want them. Families here farm a little, trade a little, commute a little, mixing rural and urban livelihoods in one household. The book reports research carried out in these parishes, with the central question being how social networks affect food security for households on the urban fringe in developing countries.

   The idea

   The urban fringe is not a suburb and not a village; it is a zone of transition where urban and rural characteristics mix and competition for land, water, and infrastructure turns fierce. The book's central research question is how social networks affect food security for households living on the urban fringe in developing countries.

   Try this: Next time you read a food security report, check whether it names where exactly the studied households live - fringe zones behave differently from city centers or villages.

2. 2Chapter 1

   Hunger is a relationship problem, not just a harvest problem

   The book's central research question is how social networks affect food security for households living on the urban fringe in developing countries. Morse and MacNamara reframe food security as being about access, and access runs through social relationships - the strength and diversity of a household's ties. They answer it with social network analysis focused on relationships, trust, and information flow.

   The idea

   Food security is usually measured at the household level, as if each family were an island with its own granary and wallet. The authors argue it is not only about production but about access, and access is mediated by social relationships and by how strong and diverse your ties are.

   Try this: List the five people you would call if your food or money ran out this week - then ask how many of them could actually deliver within a day.

3. 3Chapter 4

   Counting meals in Bwaise: 62% food insecure

   The Mugisha household has seven members. During the lean season, they reduced meal frequency from three to two per day, relying on a neighbor for 2 kg of beans per week. Using the Household Food Insecurity Access Scale, the survey found 62% of households were food insecure, with an average HFIAS score of 8.4.

   The idea

   The HFIAS turns hunger from a vague worry into a number, and the number here is stark: nearly two-thirds of households food insecure, averaging 8.4. What the scale captures is experience - eating fewer meals, eating foods you would rather not, going to sleep hungry.

   Try this: If you work with community data, add an experience-based scale like HFIAS to your next survey - meal counts and income alone will hide most of the hunger.

4. 4Chapter 5

   Your food network is three people deep - and women's run wider

   The methodology combines questionnaire surveys with social network mapping. Respondents are asked to list the people they rely on for food, money, or advice. The average household network size for food-related support was 3.2 individuals. Women had slightly larger networks (mean 3.5) than men (mean 2.9).

   The idea

   The average household network size for food-related support was 3.2 individuals. Women had slightly larger networks (mean 3.5) than men (mean 2.9), and these are the channels through which food, cash, and information move.

   Try this: Draw your own food network map with arrows for food, money, and advice - you will spot immediately which tie is load-bearing and has no backup.

5. 5Chapter 5

   Grace's church group: when one member leaves, meals halve

   Grace is a widow in Bwaise. Her lifeline is her church group, which shares food every week. When her network shrank after a key member moved away, her household went from two meals a day to one.

   The idea

   Grace's story shows network fragility: informal systems deliver real food but often lack redundancy. A church group feels permanent until its pivot person relocates.

   Try this: In any support group you belong to, identify the one or two people whose absence would break it - then deliberately build a second layer of participation.

6. 6Chapter 6

   Trust scored 5 out of 5 - and debts repaid in maize

   Peter, a boda-boda driver in Kawaala, lent money to three neighbors during a food crisis. All three repaid in kind with maize within two weeks. This reinforced his network's reciprocity norm. Trust was measured on a 5-point Likert scale; 78% of respondents rated their network contacts as 'very trustworthy' (score 5). Reciprocity showed up in 64% of food exchanges.

   The idea

   Trust is a measurable asset. On a 5-point scale, 78% gave their contacts the maximum score, and nearly two-thirds of food exchanges were reciprocal. Peter's maize repayments show why: lending is repaid, so lending continues.

   Try this: Track one informal favor you give or receive this month - notice whether repayment, in cash or kind, actually happens and what that does to your willingness to give again.

7. 7Chapter 7

   Women's ties carry cooked food; men's carry cash

   Female-headed households access food through an average of 4.1 network ties; male-headed households manage 2.7. Women's exchanges are far more likely to involve cooked food sharing, at 43% versus 18% for men.

   The idea

   Female-headed households hold 4.1 food-access ties against 2.7 for male-headed ones, and their ties lean toward cooked food sharing - 43% versus 18%. Cooked food is the most immediate form of food security there is.

   Try this: When designing a food assistance program, ask who in the household actually cooks and shares - and route information and resources to that person, not automatically to the nominal head.

8. 8Chapter 7

   Sarah's five friends beat the market by 15%

   Sarah is a market vendor. She used her network of five female friends. They pooled money for bulk maize purchases. This reduced per-kilogram cost by 15% during the lean season.

   The idea

   Sarah's network of five female friends pooled money for bulk maize purchases, reducing per-kilogram cost by 15% during the lean season.

   Try this: Organize three or more households to buy your most expensive staple in bulk this month and split it - measure the per-unit saving yourself.

9. 9Chapter 5

   Ten women, 5,000 UGX a week, 22% saved

   A group of 10 women in Kawaala formed a rotating savings club (ROSCA). Each contributed 5,000 UGX weekly. The lump sum was used to buy food in bulk. This reduced individual costs by an estimated 22%.

   The idea

   A ROSCA aimed squarely at food: each contributed 5,000 UGX weekly, and the lump sum was used to buy food in bulk, reducing individual costs by an estimated 22%.

   Try this: If your savings sit idle in small amounts, test a simple ROSCA with trusted friends for three months and put the lump sum toward a bulk purchase.

10. 10Chapter 8

    Gardening by the railway: 12% who grow also gain ties

    John, a security guard, grew vegetables on a small plot by the railway line. He gave excess sukuma wiki to three elderly neighbors weekly. Only 12% of households practiced urban agriculture, but those who did had 1.8 more food-related network ties on average than non-farmers.

    The idea

    Urban agriculture is rare on the fringe - just 12% of households - yet farmers carry 1.8 more food-related network ties than non-farmers. John gave excess sukuma wiki to three elderly neighbors weekly, strengthening his social capital.

    Try this: If you grow anything, plan the surplus deliberately: give it to specific neighbors weekly and watch how many more people you can call on within a season.

11. 11Chapter 9

    Price spikes hit 89% of households; borrowing food is the shield

    The most common shock was food price spikes, reported by 89% of households. The primary coping strategy was borrowing food from network members, used by 71% of affected households. During a 2011 maize price surge, the price rose 40% in three months. The Nakamya family survived by receiving 5 kg of maize flour weekly from a relative in the village, accessed through their network.

    The idea

    The most common shock was food price spikes, reported by 89% of households; the primary coping strategy was borrowing food from network members, used by 71% of affected households. During a 2011 maize price surge (price rose 40% in three months), the Nakamya family survived by receiving 5 kg of maize flour weekly from a relative in the village.

    Try this: If your household budget is exposed to staple price swings, identify one relative or friend in a food-producing area and invest in that relationship before the next spike.

    Dense networks, half the hunger: r = -0.61

    The Opio household, with only two network ties, experienced three months of severe food insecurity (HFIAS score 15) after the main breadwinner fell ill. Households in the highest network density quartile had a mean HFIAS score of 5.2, compared to 11.7 for the lowest quartile. This showed a strong inverse correlation (r = -0.61).

    The idea

    Network density correlates inversely with food insecurity at r = -0.61, with the densest quartile at 5.2 on the HFIAS and the sparsest at 11.7. The Opio household, with only two network ties, experienced three months of severe food insecurity (HFIAS score 15) after the main breadwinner fell ill.

    Try this: Rate your household's network density honestly: if one key person disappeared for three months, count how many remaining ties could cover food, cash, and care.

13. 13Chapter 11

    Vouchers meet the network: 20% shared onward

    A local NGO, 'Feed the Future,' provided food vouchers to 30 households in Bwaise. Recipients shared 20% of the voucher value with network members. This blended formal aid with informal networks. The chapter distinguishes between 'bonding', 'bridging' and 'linking' social capital, with bonding ties (family, close neighbors) making up 68% of food-related networks and bridging ties (NGOs, formal groups) accounting for 12%.

    The idea

    A local NGO, 'Feed the Future,' provided food vouchers to 30 households in Bwaise; recipients shared 20% of the voucher value with network members. Bonding ties (family, close neighbors) made up 68% of food-related networks and bridging ties (NGOs, formal groups) accounted for 12%.

    Try this: Before rolling out any aid or benefit, ask recipients who they will share it with - then budget for the leakage as a feature, not fraud.

14. 14Chapter 12

    Map the networks first - or break them

    Food security interventions should map existing social networks before implementation. Network-blind programs risk undermining local support systems.

    The idea

    The policy prescription is procedural: map the networks before you intervene. Support flows through specific people, women hold distinct ties, density predicts hunger, and aid gets redistributed on arrival.

    Try this: In any project you run or fund, spend the first week drawing who-helps-whom maps with the community before finalizing targeting or delivery rules.

15. 15Chapter 13

    The hidden infrastructure: 34% of hunger explained

    The book concludes that social networks act as a 'hidden infrastructure' for food security in urban fringes. Network strength explained 34% of the variance in HFIAS scores in their regression model. A line: 'Food security is not a household attribute but a relational one; it lives in the spaces between people.' (Authors Morse and MacNamara)

    The idea

    The book concludes that social networks act as a 'hidden infrastructure' for food security in urban fringes, with network strength explaining 34% of the variance in HFIAS scores in their regression model.
