  Negotiations leading up to an international climate change agreement to replace the Kyoto Protocol in 2012 have included consideration of reduced emissions due to deforestation and degradationNegotiations leading up to an international climate change agreement to replace the Kyoto Protocol in 2012 have included consideration of reduced emissions due to deforestation and degradation (REDD). This option has figured prominently in the "road map" toward such an agreement that was agreed upon during the 13th Conference of Parties to the United Nations Framework Convention on Climate Change held in Bali in December 2007 (http://www.unfccc.int/). Most ongoing discussions of REDD focus on tropical deforestation, while the potential carbon saving from reduced forest degradation is mostly disregarded [1,2]. Given that carbon losses due to degradation could be of the same magnitude as those from deforestation, this disregard is worrisome [3,4]. We show here that substantial reductions of global CO2 emissions can be achieved by improving forest management in the tropics, and argue that this cost-effective approach to mitigation should be included in the new climate change agreement....

• Technologies for Sustainable Forest Management: Challenges for the 21st Century

Some of the challenges will include the shift of production from native forest to plantations in areas of comparative advantage, more efficient processing delinking end-use products from raw wood characteristics, increased demand, better information technologies to support decision makers, and more options for conserving biodiversity. Definitions of sustainability will vary in time and space as society’s expectations and aspirations change, so there can be no 'silver bullet' to ensure sustainability. However, progress may be facilitated with a systematic approach to forest management embracing the usual planning cycle: formulation of objectives, preparation of a strategy, planning, implementing, monitoring, and reappraisal. This requires a good understanding of each particular situation. Managers need good resource assessment and decision support systems; they must foster stakeholder participation in decisions, costs and benefits; and ensure effective procedures to resolve conflicts. Within an appropriate system, technical advances such as better machines and new implements may help to make a difference, but will not in themselves ensure sustainability. The important technologies for sustainable forestry are those that foster better communication between stakeholders and allow informed decisions spanning scales from the gene to the ecosystem. This remains an important challenge for forest managers in their search for sustainability."

The global public goods value of forests is being recognized at the same time that the traditional role of state forest agencies in production forestry is being taken over by multi-national corporations. At the same time emerging technolgies are greatly enhancing our ablility to assess and monitor forest attributes.
