The objective of the LPG (Liquefied Petroleum Gas) Program in Senegal is to substitute part of the charcoal consumed in urban areas with LPG, which is mainly imported (90% of consumption). The program was initiated in 1974 following a severe period of drought in the early '70s. The first LPG cooker model that was introduced was equipped with a cylinder containing 2.75 kg of gas. Later, another, more robust, model was introduced that was fitted with a 6-kg bottle that was better suited to the cooking habits and purchasing power of the target households.
A remarkable boom occurred in the butanization process. This was due initially to tax breaks (exemption from customs duties on equipment connected with butane) and later to subsidies awarded for this fuel (in 1987). LPG use grew from less than 3,000 tons in 1974, to 15,000 tons in 1987 and nearly 100,000 tons today. This boom resulted in the diversification of cooking equipment that can be seen in households today: nearly 85% of households in Dakar (the capital) and 66% of those in the other main urban areas now own LPG stoves. Although the butanization policy may not have succeeded in fully replacing other fuels, it will have at least encouraged the diversification of cooking fuels.
