Solomon Islands must protect child nutrition and rural food systems while responding to rising noncommunicable disease. Root-crop gardens, fruit and nut trees, coastal fisheries and local markets remain central to food, income and culture. At the same time, Honiara and provincial centres are experiencing greater dependence on imported rice, flour, instant noodles, packaged snacks and sugary drinks.
Geographic dispersion makes local capacity—not national policy alone—decisive. Communities across hundreds of islands need functioning gardens and fisheries, safe water, transport, schools, clinics, medicines and referral systems. This page examines those connections without treating Solomon Islanders as one genetically or culturally uniform population.
A 2024 UNICEF country factsheet reported that Solomon Islands has among the Pacific’s highest rates of childhood stunting and underweight. In 2025, UNICEF’s Eating Local, Eating Healthy programme cited national survey estimates of 32% stunting, 8% wasting and 39% anaemia among children under five, while also reporting overweight and obesity among adolescents. These indicators refer to different age groups and definitions and should not be combined into one prevalence figure.
This is the double burden of malnutrition: insufficient dietary quality, infection and poor maternal or childhood nutrition can persist while energy-dense processed foods and sugary drinks increase excess weight and later NCD risk. The response must protect breastfeeding, maternal nutrition, diverse complementary feeding, micronutrients, water and sanitation while also creating healthier school and retail environments.
Cassava, sweet potato, taro and yam are important staples, but their prominence varies by island, soil and season. Breadfruit, banana and other tree crops can provide additional resilience. Ngali nuts are a distinctive local food and potential livelihood crop, while leafy vegetables, fruit, legumes, fish and other protein foods help turn a starch staple into a more complete meal.
No root crop is automatically “safe” or “dangerous.” Preparation, portion and the foods eaten with it matter. A large plate dominated by starch has a different nutritional profile from a meal that combines a moderate staple portion with vegetables and protein foods. The goal is dietary diversity, not the replacement of one refined carbohydrate with an equally monotonous local diet.
Cassava is resilient, grows in varied soils and can remain in the ground until needed, making it useful during difficult seasons. FAO’s Solomon Islands cassava profile describes its use in family gardens, rural boarding schools, training centres and peri-urban production. It can support both food security and income.
Cassava must be processed correctly because naturally occurring cyanogenic compounds can be harmful when unsuitable varieties or methods are used. It is also primarily a starch. Programmes that expand cassava production should therefore promote safe preparation and combine it with vegetables, legumes, nuts, fish or other protein foods.
Fish and shellfish provide food, income and cultural continuity. Their contribution depends on reef health, sustainable harvesting, weather, fuel, boats, storage and market access. When households must sell much of their catch to purchase imported staples, the apparent availability of seafood does not guarantee that families consume adequate protein.
Coastal management is therefore a health intervention as well as an environmental one. Community-led fisheries, protected nursery areas, safe handling, cold storage and transport can help retain nutritional and economic value locally.
Urban growth changes the food environment. Rice, flour, instant noodles, sweetened drinks, packaged snacks and processed meats are convenient, shelf-stable and often easier to transport than perishable local foods. Imported food is essential after disasters and during shortages; the concern is routine displacement of varied meals by products high in refined starch, added sugar or salt.
Consumers cannot choose foods that are unavailable or unaffordable. The National Assessment of the Solomon Islands Food System identifies three connected pathways: strengthen rural food systems, improve the policy environment and create healthy food environments that are accessible, affordable and convenient. Better rural–urban connections are central to all three.
Declining soil fertility, erosion and shortened fallow periods can reduce harvests and push families toward imported staples. A 2025 Pacific Community report from Sairagi Village described soil testing, contour farming, vetiver grass and tailored composting as responses to falling yields. The lesson is larger than one village: nutrition policy begins with the soil that supports local food.
Farmers need extension services, planting material, land-management support, transport, storage and fair markets. Women farmers and vendors should participate in programme design and gain equitable access to training, finance and decision-making.
WHO reports that cardiovascular disease, diabetes, cancer and chronic respiratory disease are leading causes of death in Solomon Islands. These conditions require prevention, early detection and long-term treatment in a health system historically designed largely for acute illness.
The Solomon Islands Package of Essential NCD interventions shows what decentralisation can look like: provincial NCD coordinators use cardiovascular-risk assessment, manage records, consult remotely with Honiara and provide medicines closer to patients. Demonstration gardens and nutrition education connect clinical care with the local food environment.
Screening is only valuable when blood-pressure, glucose, kidney or cardiovascular findings lead to counselling, medicines, referral and follow-up. Geographic access, medicine supply and record systems are therefore metabolic-health interventions.
Solomon Islands populations are culturally and genetically diverse. Some inherited variants may influence glucose regulation, lipid metabolism, body-fat distribution or uric-acid transport, while family history may identify people who could benefit from earlier assessment. However, common metabolic diseases arise through interactions among many genes and many exposures.
There is no single “Solomon Islands gene” that explains diabetes, obesity or kidney disease. Ancestry is not a diagnosis. Research should identify the particular population studied and avoid generalising results from another Pacific country—or from one Solomon Islands community—to everyone.
Cyclones and floods can destroy gardens, damage water systems, interrupt shipping and cut communities off from clinics. Immediately after a disaster, packaged and canned foods may be the safest available supplies. That emergency dependence should not be portrayed as a failure of culture or individual discipline.
Recovery should restore food gardens, planting material, fishing capacity, safe water and essential health services quickly. Nutrition surveillance must identify young children, pregnant women, older adults and people with diabetes or other chronic conditions who face particular risk when normal food and medicine supplies fail.
The Eating Local, Eating Healthy initiative links school food with local agriculture and water, sanitation and hygiene services. This model can improve children’s meals while creating demand for growers. School programmes should use transparent food standards, safe water, practical procurement and monitoring rather than relying only on classroom messages.
School gardens are most valuable when connected to meals, agricultural knowledge, families and local producers. They should complement—not replace—adequate school funding and dependable food provision.
