Al-Shabaab attacks in Somalia affect communities as far as 900km away – aid agencies need to take note
Policymakers tend to assume that the effects of conflict are felt only where violence occurs. As a result, humanitarian aid, protection efforts or asylum policies largely focus on conflict-hit areas.
The World Health Organisation, for instance, provides emergency medical supplies in areas directly affected by violence. The UN Refugee Agency ties protection status to residing in areas hit by conflict.
Our recent study finds, however, that conflict negatively affects food security, nutrition, health and education outcomes of families living hundreds of kilometres away from the epicentre of violence.
This underscores the need to broaden policy responses to conflict and consider its ripple effects.
Our research in Somalia examined how the impact of violent conflict spread to distant locations. We looked specifically at conflict that affected Somalia’s food logistics network, which gets food to far-flung markets.
We focused on Somalia because of its high number of terror incidents arising from the government’s war with Al-Shabaab, a militant group that has terrorised the country’s southern region for about 15 years.
Al-Shabaab is just a symptom of Somalia’s tragedy – the causes are still in place
We used data from the Food and Agricultural Organisation, which tracks food prices. Our results show that terrorist attacks that hit food transportation networks increased food prices in markets located up to 900km away (a 17-hour drive) from where the violence occurs.
In response to these terrorist attacks and resulting price increases, households in far-flung areas adjusted their eating patterns. They also reduced their non-food spending, primarily on health and education.
Yet, the responses to violent incidents by donor and aid agencies, as well as domestic policymakers, hardly take such ripple effects into consideration.
To track these ripple effects, we focused on the distribution of maize, a staple food eaten throughout Somalia. We got the geo-coordinates of maize growing areas, tracked how maize was transported by road to markets, and mapped the Al-Shabaab terrorist attacks that occurred along these transport routes.
This helped us map the impact of conflict on maize prices and the ripple effects on household welfare.
The Famine Early Warning Systems Network provides maps showing the exact routes taken by Somali drivers who are transporting maize. We drew a corridor of five kilometres around these roads and counted the number of violent incidents occurring each month between 2001 and 2018. The Food and Agricultural Organisation provided us with monthly maize price information for 10 markets across Somalia.
We combined this data with World Bank surveys that recorded food consumption, eating patterns, and the health and education of Somali families.
We found that conflict along transportation roads increased maize prices substantially, even in markets located hundreds of kilometres away. This finding is in line with studies on the impact of conflict on supply chain networks elsewhere in the world, such as in the Russia-Ukraine war.

During the height of the Al-Shabaab insurgency in Somalia (between 2016 and 2018), violent incidents occurring very close to transportation roads alone increased maize prices by around 11% over sustained periods of time.
During these times, we found violence en route had around half as large an impact on maize prices as rainfall, which the World Bank has highlighted as one of the most important determinants of food prices.
We also scrutinised satellite images of nightlights emitted on transportation roads. We found that conflict along transit roads dimmed the light emitted on these roads several hundreds of kilometres away. This decrease in road traffic underscores a reduction in the quantity of maize transported along roads from growing areas to markets.
Looking at family welfare, we found that households reported having to adjust their eating patterns due to food price shocks. Families substituted the more expensive maize with sorghum. Still, we found that lower food security decreased the nourishment available to households.
Considering child outcomes, we found that far-away conflict along transit routes increased the incidence of diseases, such as gastroenteritis, malaria and typhoid. This is in line with well-known links between malnutrition and infectious diseases.
Finally, we also found a decrease in the school enrolment of children. Violent incidents along maize transportation routes reduced the probability of children joining primary and middle school hundreds of kilometres away. This is likely to be related to the economic effects of food price rises. This makes schooling less affordable and increases the incentives for child labour.
Our study has wide-ranging policy implications.
The ripple effects of violence have important welfare costs. The negative effects of conflict on human capital – particularly nutrition, health and education – are larger than commonly assumed. We estimate that these ripples add around 30% to the cost of locally occurring conflict.
Our findings also have important implications for the regional targeting of policies.
Humanitarian interventions or refugee policies most commonly focus on those locations where conflict occurs. The World Food Programme, for instance, provides nutritional assistance in areas around Mogadishu, in the south-west of Somalia where most conflict is concentrated.
Similarly, when evaluating asylum eligibility, the UN Refugee Agency highlights the south-west of Somalia as the area where individuals are at risk of serious harm.
By contrast, our results provide evidence that individuals can be affected by conflict even if it occurs far away. For instance, the city of Galkayo (700km from Mogadishu) is part of the north-eastern Puntland state. It isn’t covered by either the World Food Programme or the UN’s refugee policies. Yet conflict in the south-west increases food prices, decreases food security and erodes human capital in Galkayo.
This long reach of violence highlights the need to consider extending humanitarian aid, protection efforts or asylum status eligibility to areas further away from conflict epicentres.
