Ⅳ. WOOD FUELS: THE VANISHING RESOURCE
64. Seventy per cent of the people in developing countries use wood and, depending on availability, burn anywhere between an absolute minimum of about 350 kilogrammes to 2,900 kilogrammes of dry wood annually, with the average being around 700 kilogrammes per person.[1] Rural woodfuel supplies appear to be steadily collapsing in many developing countries, especially in sub-Saharan Africa.[2] At the same time, the rapid growth of agriculture, the pace of migration to cities, and the growing numbers of people entering the money economy are placing unprecedented pressures on the biomass base[3] and increasing the demand for commercial fuels: from wood and charcoal to kerosene, liquid propane, gas, and electricity. To cope with this, many developing country governments have no option but to immediately organize their agriculture to produce large quantities of wood and other plant fuels.
65. Wood is being collected faster than it can regrow in many developing countries that still rely predominantly on biomass wood, charcoal, dung, and crop residues for cooking, for heating their dwellings, and even for lighting. FAO estimates suggest that in 1980, around 1.3 billion people lived in wood-deficit areas.[4] If this population-driven overharvesting continues at present rates, by the year 2000 some 2.4 billion people may be living in areas where wood is 'acutely scarce or has to be obtained elsewhere'. These figures reveal great human hardship. Precise data on supplies are unavailable because much of the wood is not commercially traded but collected by the users, principally women and children. But here is no doubt that millions are hard put to find substitute fuels, and their numbers are growing.
66. The fuelwood crisis and deforestation, although related, are not the same problems. Wood fuels destined for urban and industrial consumers do tend to come from forests. But only a small proportion of that used by the rural poor comes from forests. Even in these cases, villagers rarely chop down trees; most collect dead branches or cut them from trees.[5]
67. When fuelwood is in short supply, people normally ecomomize; when it is no longer available, rural people are forced to burn such fuels as cow dung, crop stems and hucks, and weeds. Often this does no harm, since waste products such as cotton stalks are used. But the burning of dung and certain crop residues may in some cases rob the soil of needed nutrients. Eventually extreme fuel shortages can reduce the number of cooked meals and shorten the cooking time, which increases malnourisment.
68. Many urban people rely on wood, and most of this is purchased. Recently, as the price of wood fuels has been rising, poor families have been obliged to spend increasing proportions of their income on wood. In Addis Ababa and Maputo, families may spend a third to half of heir incomes this way.[6] Much work
