IntroductionBiomass fuels contribute to the largest share of the energy uses in Bangladesh. Currently, biomass is the fourth largest source of energy which supplies 15% of the energy use in the world (Sudha & Ravindranath 1998). Only in the developing countries, traditional biomass fuels meet a large percentage (38%) of the total energy needs (Sudha et al. 2003). In some countries like Bangladesh, its use is as so high as 75-90%, mainly used for cooking and heating (Sudha et al. 2003). Woody and non-woody biomass in the form of fuelwood, crop residues and cowdung dominates as the energy source in the low income country. Rural households are the major consumer in this respect.About 77% of the populations in Bangladesh live in the rural areas and they need energy for their domestic use like cooking, crop processing, lighting, agricultural industries, social welfare and commercial activities (BBS 2006). Because of over exploitation of natural and homestead forests, fuel shortage intensity is being increased day by day. In Bangladesh, biomass plays an important role, especially in the rural areas, where most of the people live. The overuse of fuelwood is significantly sharing the deforestation process. In addition to this, there is an increased use of crop residues and cowdung as fuel which is depriving the agricultural soil of valuable nutrients and organic matter. However, the fuel choice by the households is influenced by the income, family size, educational status and the occupation of the household members (Rao & Reddy 2007). Sarker & Islam (1998) studied the household biomass fuel energy situation in the poor forest regions of Bangladesh. Miah et al. (2003) studied the biomass fuel use by the rural households in Chittagong region, Bangladesh. Jashimuddin et al. (2006) investigated the preference and consumption pattern of biomass fuel in some disregarded villages of Bangladesh. Akhter et al. (1999) studied the homestead biomass fuel energy situation of a forest rich district, Cox's Bazar. Rao & Reddy (2007) studied the variations of energy use by Indian households. Wijayatunga & Attalage (2002) analyzed the household cooking energy demand and its environmental impact in Sri Lanka. Xiaohua & Zhenming (1996) carried out a survey of rural household energy consumption in China.To know the biomass consumption and expenditure pattern in the rural households, no study was so far found in the Meghna floodplain zone of Bangladesh. Thus, the study was conducted to understand the biomass fuel consumption and its expenditure by the rural households in the specified geographical location. The findings of the study are expected to contribute to the sustainable energy development in Bangladesh.
