To date, little has been done in working with communities to identify appropriate and affordable interventions to remove smoke. A study carried out by the Intermediate Technology Development Group (ITDG) has shown that appropriate low-cost interventions (smoke hoods, eaves spaces) could reduce smoke and personal exposures substantially in two rural communities in Kenya.

A follow-up project, funded by the UK Department for International Development (DFID), aims to identify the best mechanisms for scaling-up a variety of successful interventions to reduce indoor air pollution. ITDG is currently undertaking this study in three countries:

  • an urban community in Kisumu, Kenya - using wood, charcoal and agricultural residues as their main cooking fuels

  • a community near Kassala, Sudan, where a large influx of displaced people has made access to biomass fuels problematic

  • Gatlang, a mountainous region in northern Nepal, where communities rely on biomass for space heating as well as cooking

An assessment of exposures to indoor air pollution and health outcomes in all three countries, undertaken by ITDG in close collaboration with the University of Liverpool and WHO, forms a key part of this project. Dissemination of results and lessons learnt may help inform similar intervention projects in different settings and countries.
