Supply and demand for wood as a source of energy in Zambia: An econometric analysis
This study examines the status of biomass energy in Zambia. In its current usage, the concept of biomass energy often implies woodfuel because woodfuel is the main biomass energy. This study develops an econometric model of household woodfuel demand and also evaluates the supply of woodfuel in Zambia. The study finds that there are significant sectoral differences in woodfuel demand between the rural and urban sectors. In the rural sector, inflation is by far the most significant determinant of household woodfuel demand. The coefficients on inflation are statistically significant at better than the one percent level and also have expected positive signs. In the urban sector, inflation is again by far the most significant determinant of woodfuel demand. However, in the urban sector, household income and woodfuel price are also significant determinants of demand. The coefficients on inflation, household income, and woodfuel price are all significant at better than the one percent level and have expected signs. The income elasticity of woodfuel demand is positive, suggesting that in the short-run, woodfuel is a normal good. However, the elasticity of woodfuel demand with respect to growth in investment is negative, indicating that long-run structural change in the economy reduces woodfuel demand.
