REDD and Clean Technologies Innovations: Is There a Trade-Off?
A key policy question when discussing REDD is how to balance low-cost forestry emission reductions, available in the near term, with investments to drive technological innovation in energy, industry, and other sectors over the longer period. In this article we report a research effort showing that the link of REDD to an international carbon market is, as expected, economically efficient. In addition, provided that the climate policy is stringent (we explore here a 535 ppmv CO2e concentration target), the cost savings due to REDD should entail only a modest tradeoff in terms of reduced clean energy innovation. Reduced clean energy innovation could in principle handicap future efforts to reduce global emissions. However, this analysis suggests that the availability of REDD, in particular when combined with the possibility of banking emission allowances, could provide a head start on climate mitigation that is an aggregate hedge against uncertain future costs. Integrating REDD into global carbon markets could thus lower policy costs and facilitate more ambitious climate policies now and in the future.
Reducing carbon emissions from deforestation and forest degradation: issues for policy design and implementation
There is a new international policy focus on reducing emissions from deforestation and forest degradation (REDD), as well as promoting forest conservation, the sustainable management of forests and the enhancement of forest carbon stocks (REDD-plus). The recent Conference of Parties meeting of 196 countries of the United Nations Framework Convention on Climate Change (UNFCCC) in Cancun, Mexico (December 2010) was able to advance initiatives on REDD-plus even while there was limited progress on fossil fuel related aspects of an international climate change agreement. The Cancun meeting recognised that there was strong and broad support for REDD-plus and was able to agree to the development of a formal Mechanism under the UNFCCC for incentivizing REDD-plus activities. Implementing the Mechanism is another matter, and will require the development and coordination of country REDD-plus readiness and financing, including detailed consideration of country reference levels, measurement, reporting and verification methodologies, and sub-national and national program coordination.
The development of biological systematics : Antoine-Laurent de Jussieu, nature, and the natural system
A reevaluation of the history of biological systematics that discusses the formative years of the so-called natural system of classification in the eighteenth and nineteenth centuries. Shows how classifications came to be treated as conventions; systematic practice was not linked to clearly articulated theory; there was general confusion over the "shape" of nature; botany, elements of natural history, and systematics were conflated; and systematics took a position near the bottom of the hierarchy of sciences.
