Shifts in consumption

Interventions targeting shifts in consumption of forest products have a direct effect on timber demand and, thus also affect the need for forestry areas in production (PBL, 2010). The increase in demand could concern industrial roundwood or paper, but also wood as traditional bioenergy. As a first-order effect, an intervention to change demand for industrial products reduces all upstream effects of production proportionally. Data on wood for traditional biomass are not available, and estimates vary greatly partly due to whether the focus is on use or production. With estimates ranging from 1300 Mt/y (FAO, 2013a) to 2400 Mt/y (IEA, 2012), a considerable proportion of the total wood use can be attributed to fuelwood. A decrease in wood use for traditional biomass has fewer direct impacts on the IMAGE biodiversity results than decreases in other uses, because only part of the production is harvested in industrial forestry activities (see Component Forest management). Large quantities of fuelwood are collected or produced in areas smaller than included in the level of detail of the IMAGE framework, such as orchards and road-sides. This implies that interventions related to this kind of use do not completely show up in biodiversity impacts.

Bio-energy demand

Bioenergy demand will affect demand for forestry products for the energy sector, with effects similar to those expected under the shifts in consumption. The impact on biodiversity will depend on the sustainability criteria, management practices, and regions in which timber is harvested.

‎Implementation of sustainability criteria in bio-energy production	Sustainability criteria that could become binding for dedicated bio-energy production, such as the restrictive use of water-scarce or degraded areas.	Emissions Energy supply(*) Terrestrial biodiversity

Improve forest management

Improving forest management will affect the area required to meet timber demand and the impact of timber harvest on biodiversity loss. A system of Reduced Impact Logging (RIL), which relates to improvements that can be implemented in selective logging management, could reduce harvest damage, stimulate regrowth and maintain biodiversity (Putz et al., 2012). In addition, dedicated plantations could be established and would reduce the area of natural forest needed for timber harvest, since wood production is higher in plantation areas. However, biodiversity values of those areas are relatively low.

Policy intervention	Description	Implemented in/affected component
More sustainable forest management	Sustainable forest management aims for maintaining long-term harvest potential and good ecological status of forests (e.g. the nutrient balance and biodiversity). This can be implemented by (i) enlarging the return period when a forest can be harvested again; (ii) only using certain fractions of the harvested biomass and leave the remaining part in the forests.	Carbon cycle and natural vegetation Forest management(*)
Expanding Reduced Impact Logging	Increasing the share of produced wood yielded with Reduced Impact Logging (RIL) practices instead of conventional logging practices.	Carbon cycle and natural vegetation Forest management(*) Terrestrial biodiversity
Increase forest plantations	Increase the use of wood from highly productive wood plantations instead of wood from (semi-) natural forests.	Carbon cycle and natural vegetation Forest management(*) Terrestrial biodiversity
