Multiple land use practices in forests, in particular those that end in deforestation, lead to emissions of carbon dioxide (CO2) and, if the biomass is burned during the clearing process, additional non-CO2 gases are emitted (Penman et al 2003, Denman et al 2007). 1.2. 1.3. 2. 2.1. 2.2. 3. 3.1.

Reducing Emissions from Deforestation, Forest Degradation, Conservation of carbon stocks, sustainable Management of Forest, and Enhancement of Carbon Stocks (REDD+) builds on reliable estimates of forest carbon stocks at the national level. Methods to estimate national-level forest carbon stocks are either based in biome averages, forest inventories, or remote sensing (Gibbs et al. 2007). While direct remote sensing based approaches using LIDAR, Radar, or very high-resolution optical sensors show promising results at the subnational level (TOLLEFSON 2009), inventory based methods are still needed to calibrate new methods and to provide data required for other purposes. Inventory based carbon stock assessment are either implemented using biomass expansion factors (the so called indirect approach mainly used in national forest inventories) or allometric equations as recommended by the IPCC Good Practice Guidance on Land Use Land-Use Change and Forestry (IPCC GPG-LULUCF 2003).

Forests sequester and store more carbon than any other terrestrial ecosystem and are an important natural `brake' on climate change.
Political acceptance and implementation of climate policies aimed at reducing carbon emissions from deforestation will require resolution of scientific challenges. 2. 3. Oliveira.SOM. Methods to measure carbon. Measuring and assessing forest degradation. Deforestation and forest degradation factors. Jean-Paul Lanly1 Abstract An accurate analysis of deforestation and forest degradation requires that clear distinctions be made between these two terms, between the factors and underlying causes of these processes and between direct (e.g. the different forms of agriculture) and indirect (e.g. the development of logging road infrastructure)factors. A very large number of deforestation studies, essentially in the tropics, were carried out in the last 40 years at all levels and were facilitated by remote sensing. However they seldom included an objective assessment of the respective share of the various direct deforestation factors. Introduction Causes and factors It is important at the outset to carefully distinguish between the underlying causes of deforestation and forest degradation, about which there might be divergent views, and the actual factors, which could be part of the area of objective observation.
