Social Challenge

In Peru, 42% of households use firewood, charcoal, manure and/or agricultural waste as fuel for cooking. In rural areas, 82% of households use biomass, mainly wood and dung, materials that are highly pollutant and harmful to health. This has led to an increase in the rate of pulmonary disease among rural communities, particularly women and children.
