What measures are most effective in reducing respiratory illness linked to indoor cooking with solid fuels in humanitarian settings?

• A. Increase use of solid fuels for efficiency
• B. Install clean stoves and improve ventilation
• C. Close all cooking areas to prevent emissions
• D. Rely on outdoor cooking with cleaner fuels

Answer: (B)

Reducing exposure to indoor air pollution from solid-fuel cooking comes from cutting emissions at the source and lowering how concentrated those pollutants become inside living spaces. Installing clean stoves improves combustion and lowers emissions of smoke and toxic gases, while good ventilation dilutes and exhausts what’s released, making it safer for people who cook and live nearby. In humanitarian settings, this combination is practical: it addresses both the amount of pollution generated and how people are exposed, even when solid fuels are still in use and fuel options are limited. Relying on more solid fuels would worsen pollution; closing cooking areas traps heat and smoke indoors, creating hazards; and outdoor cooking, while helpful for indoor air, isn’t always feasible due to weather, space, safety, or cultural reasons, and it may not protect everyone in the shelter.
