In most developing countries, the majority of households uses solid fuels like wood or charcoal for cooking purposes. Woodfuel usage for cooking purposes is associated with various negative effects on the health, gender, and the disposable income of households. Furthermore, in countries with rather low biomass production such as Senegal, this reliance on woodfuels may cause wood to be extracted in an unsustainable manner. Against this background, in many countries GIZ supports the dissemination of improved cooking stoves that are expected to significantly reduce the wood or charcoal consumption per meal. RWI evaluates GIZ’s improved stove dissemination program in Senegal, which has contributed to the commercialization of over 70 000 improved stoves between 2006 and 2009. Virtually all of these 70 000 stoves were marketed in the cities of Kaolack and Dakar. As a consequence, the present evaluation concentrates on these urban regions. The research focus is on the impact improved stove usage potentially has on charcoal consumption, respiratory disease symptoms, time usage, and energy expenditures. In the urban intervention areas of the GIZ program, both stove using and non-using households were surveyed by a random sample among target region households. In total, around 620 households were interviewed using a structured questionnaire. The virtue of the collected data is the detailed information on meal specific features. Therefore, it cannot be only controlled for household characteristics, but also for meal specific differences such as the type of dish prepared during a certain application of the stove or the number of people the meal is prepared for. Using multivariate models and matching approaches to compare improved stove users and non-users, the impact of improved stove usage on charcoal consumption and other indicators it can thereby be estimated.
