With women spending on average more than five hours a day cooking on stoves fuelled mainly by wood, they are exposed to such high levels of indoor air pollution (IAP) that many face premature death. But with the introduction of the new clean and efficient Patsari cookstove into over 2000 homes, marked improvements in respiratory illnesses and eye related conditions have been evident. The project, part of the charitys overall Breathing Space programme which aims to achieve a significant long-term reduction in IAP by helping develop technology to make stoves more emission and fuel efficient, involved a partnership of several governmental, academic and NGOs from Mexico and the US. It was the first of its kind run in Mexico with the development of an integrated approach to a cooking stoves programme, monitoring of health benefits, ability to scale up and having an impact on public policy all key aims of the initiative. Field studies were conducted in 30 villages in the rural highlands of the Purepecha region, 300 families being provided with a new Patsari stove and a further 300 – the control group - continuing with existing practices. Researchers filled in extensive questionnaires, took blood tests and lung function readings before and after the study period and made monthly visits to the participating families. Headline results from the study, which concluded at the end of 2006, were: Breathing Space Business Manager Sanyogita Seksaria said she was delighted with the results, adding: It is now clear that in the Patsari stove we have a product that rural households are happy to use instead of their traditional open fires and one which offers them real health benefits.

Shell Foundation stove project leads to significant health benefits for Mexican families


A Shell Foundation programme putting over 2000 low emission cook stoves into households in several regions of Mexico has led to ‘significant and tangible health benefits’ according to scientists conducting the research.


A Woman carries fuel wood.

With women spending on average more than five hours a day cooking on stoves fuelled mainly by wood, they are exposed to such high levels of indoor air pollution (IAP) that many face premature death.

But with the introduction of the new clean and efficient Patsari cookstove into over 2000 homes, marked improvements in respiratory illnesses and eye related conditions have been evident.

The project, part of the charity’s overall Breathing Space programme which aims to achieve a significant long-term reduction in IAP by helping develop technology to make stoves more emission and fuel efficient, involved a partnership of several governmental, academic and NGOs from Mexico and the US. It was the first of its kind run in Mexico with the development of an integrated approach to a cooking stoves programme, monitoring of health benefits, ability to scale up and having an impact on public policy all key aims of the initiative.

Field studies were conducted in 30 villages in the rural highlands of the Purepecha region, 300 families being provided with a new Patsari stove and a further 300 – the control group - continuing with existing practices. Researchers filled in extensive questionnaires, took blood tests and lung function readings before and after the study period and made monthly visits to the participating families.

Headline results from the study, which concluded at the end of 2006, were:

  • A 70% reduction in overall IAP, including a 60% reduction in personal exposure for those using the Patsari stove
  • An improvement of between 14 and 35% in respiratory illnesses in women and children
  • An improvement in eye related illnesses of between 35 and 49%
  • 60% savings in fuelwood consumption compared to the traditional open fires
  • For each dollar invested in a Patsari stove the Mexican Health Ministry saved seven dollars.

Breathing Space Business Manager Sanyogita Seksaria said she was delighted with the results, adding: “ It is now clear that in the Patsari stove we have a product that rural households are happy to use instead of their traditional open fires and one which offers them real health benefits. This project was critical to place the stoves on the agenda of the Environment, Health and Social Development Ministries in Mexico and our aim is now to replicate this model in other regions in Mexico and eventually other Latin American countries too.”
