Map of Evidence: interventions to reduce exposure to household air pollution

    Publication year: 2021

    This evidence map was developed to identify, summarize, and communicate to key stakeholders the findings of evidence on interventions to reduce exposure to household air pollution (HAP). The map synthesizes evidence from 48 literature reviews published on technological and sociocultural interventions and others (potentialities of public policies like incentives) to address health, environmental and economic impacts associated to HAP. Furthermore, this map seeks to inform decision-making processes on strategic interventions and most effective policies.

    Main results:

    Most of the existing HAP interventions to address indoor air quality have been focused on evaluating improved stove interventions that still use solid fuels (n = 39). It has been identified that Interventions with clean fuels (LPG, electricity, and others) are the most effective in impacting the health outcomes and reducing household air pollutants. Only six reviews analyzed or reported outcomes of sociocultural interventions (health education) aimed at reducing air pollution in homes; some showed positive impacts on health. Three reviews reported the effects of changes in people's behaviors when cooking food, which have improved indoor air quality. All authors agree on the importance of changing behavior and community practices as an essential element for the sustainability of improved kitchen interventions. Four reviews evaluated at the synergy between policies to reduce household air pollution and outdoor pollution, as well as other environmental health concerns. These reviews allow the conclusion that synergies between policies are much more effective at reducing air pollution and its impacts on the health of communities.
