Home Gardens for Rohingya Mothers in Cox's Bazar Cut Household Food Insecurity by 66% in a Trial

A cluster-randomised trial of 1,050 pregnant and breastfeeding women in the Rohingya refugee camps of Cox's Bazar, Bangladesh, tested gardening and nutrition support delivered by Concern Worldwide and SHED, with the International Rescue Committee leading the evaluation. Women who got support were 17 percentage points more likely to have a garden, and their households were 57 points more likely to source fruit and vegetables from their own gardens. Household food insecurity fell by 66% and fruit intake rose by about one serving a week. The trial found no significant rise in vegetable intake or overall dietary diversity, and lack of space was the biggest constraint. Results were published on 15 May 2026.
