In Mexico, nearly 25 million people rely on fuelwood as their main energy source for cooking. Some 17 million use it exclusively and 8 million use it in combination with LPG (INEGI, 2000, Masera, 2005). Cooking is typically done on threestone open fires (known locally as fogones), a deeply-rooted tradition associated with extensive fuelwood use, the release of various pollutants due to incomplete combustion, and health impacts caused by exposure of women and children to smoke (Smith, 2000). To help solve these problems, a multi-institutional and integrated project was launched in the Central Mexican Highlands aimed at the dissemination of improved woodburning
cookstoves (ICS) (Masera et al. 2005). A new model of ICS, called “Patsari” was developed, along with an innovative dissemination strategy that includes a participatory users‘-centered approach. The project includes comprehensive monitoring of user preferences and attitudes, and ICS impacts on: fuelwood savings and other parameters related to stove performance, greenhouse gas emissions, health and indoor air pollution.
