Dirty versus clean fuel for cooking in Pakistan: regional mapping and correlates

Based on the Pakistan Demographic and Health Survey (PDHS) 2017-18 data, the study intends to present the relative status of a particular fuel (type) in terms of its level of use in different regions of Pakistan. At the same time, the study investigates the determinants of the household type of fuel used for cooking in Pakistan. Socioeconomic characteristics of the households and household heads are taken as determinants of the main type of fuel (clean or dirty) used for cooking by the households. Binary logistic regression is applied as an estimation technique. Over the country, wood stands first as the most widely used type of fuel followed by natural gas followed by LPG. Animal dung and charcoal are respectively ranked as the fourth and fifth most commonly used types of fuel for cooking by households in Pakistan. In comparison amongst the four provinces of Pakistan, the use of wood as well as charcoal as the fuel type for cooking (in relative terms) is the most common in Balochistan province. Likewise, Punjab province is the most frequent user of liquefied petroleum gas (LPG), crop residues, and animal dung, while Sindh province is the most frequent user of natural gas. Households possessing agricultural land and livestock and with large household sizes had more probability to use dirty sources of fuel for cooking. Households with better wealth status and residing in urban areas were more likely to use clean sources of fuel for cooking. Household head's higher educational status and male-gender had more likelihood to use clean sources of fuel for cooking.
