The water footprint of wood for lumber, pulp, paper, fuel and firewood

摘要: Abstract This paper presents the first estimate of global water use in forestry sector related to roundwood production for lumber, pulp, paper, fuel and firewood. For period 1961–2010, we forest evaporation at a high spatial resolution level attribute total consumption various products, including ecosystem services. Global increased by 25% over 50 years 961 × 109 m3/y (96% green; 4% blue) 2001–2010. The footprint per m3 wood is significantly smaller (sub)tropical forests compared temperate/boreal forests, because host relatively more value next form other In terms economic productivity energy yield from bio-ethanol unit water, rather comparable with major food, feed crops. Recycling products could effectively reduce sector, thereby leaving available generation Intensification can only if additional ha outweighs loss services, which often not case forests. results this study contribute complete picture human appropriation thus feeding debate on food or versus wood.
