This anticipated growing domestic demand for industrial roundwood will partly be caused by population growth and partly by growing welfare levels. Comparing the demand for industrial wood per capita of developed countries with that of developing countries (1.1 m3 and 0.09 m3 respectively - World Watch Paper 83 and SBH, data 1986 in Otto, 1990, Table 2), a higher welfare level in the developing countries will probably result in a growing demand. If the welfare level of the developing countries would rise to the same level as that of the western countries currently, and the demand for industrial wood rose accordingly, the use of industrial roundwood would rise from 360 million to 4100 million cubic metres a year!
