Measuring forest degradation and related forest carbon stock changes is more challenging than measuring deforestation since degradation implies changes in the structure of the forest and does not entail a change in land use, making it less easily detectable through remote sensing. Although we anticipate the use of the IPCC guidance under the United Framework Convention on Climate Change (UNFCCC), there is no one single method for monitoring forest degradation for the case of REDD+ policy. In this review paper we highlight that the choice depends upon a number of factors including the type of degradation, available historical data, capacities and resources, and the potentials and limitations of various measurement and monitoring approaches. Current degradation rates can be measured through field data (i.e. multi-date national forest inventories and permanent sample plot data, commercial forestry data sets, proxy data from domestic markets) and/or remote sensing data (i.e. direct mapping of canopy and forest structural changes or indirect mapping through modelling approaches), with the combination of techniques providing the best options. Developing countries frequently lack consistent historical field data for assessing past forest degradation, and so must rely more on remote sensing approaches mixed with current field assessments of carbon stock changes. Historical degradation estimates will have larger uncertainties as it will be difficult to determine their accuracy. However improving monitoring capacities for systematic forest degradation estimates today will help reduce uncertainties even for historical estimates.

The United States needs many different types of forests: some managed for wood products plus other benefits, and some managed for nonconsumptive uses and benefits. The objective of reducing global greenhouse gases (GHG) requires increasing carbon storage in pools other than the atmosphere. Growing more forests and keeping forests as forests are only part of the solution, because focusing solely on the sequestration benefits of the forests misses the important (and substantial) carbon storage and substitution GHG benefits of harvested forest products, as well as other benefits of active forest management.

Forests and global climate are closely linked in terms of carbon storage and releases, water fluxes from the soil and into the atmosphere, and solar energy capture. Understanding how carbon dynamics are affected by stand age, density, and management and will evolve with climate change is fundamental to exploiting the capacity for sustainably managed forests to remove carbon dioxide from the atmosphere. For example, even though temperate forests continue to be carbon sinks, in western North America forest fires and tree mortality from insects are converting some forests into net carbon sources.

Expanding forest biomass use for biofuels and energy generation will compete with traditional forest products, but it may also produce benefits through competition and market efficiency. Short-rotation woody crops, as well as landowners' preferences—based on investment-return expectations and environmental considerations, both of which will be affected by energy and environmental policies—have the potential to increase biomass supply.

Unlike metals, concrete, and plastic, forest products store atmospheric carbon and have low embodied energy (the amount of energy it takes to make products), so there is a substitution effect when wood is used in place of other building materials. Wood used for energy production also provides substitution benefits by reducing the flow of fossil fuel-based carbon emissions to the atmosphere.

The value of carbon credits generated by forest carbon offset projects differs dramatically, depending on the sets of carbon pools allowed by the protocol and baseline employed. The costs associated with establishing and maintaining offset projects depend largely on the protocols' specifics. Measurement challenges and relatively high transaction costs needed for forest carbon offsets warrant consideration of other policies that promote climate benefits from forests and forest products but do not require project-specific accounting.

Policies can foster changes in forest management and product manufacture that reduce carbon emissions over time while maintaining forests for environmental and societal benefits. US policymakers should take to heart the finding of the Intergovernmental Panel on Climate Change in its Fourth Assessment Report when it concluded that “In the long term, a sustainable forest management strategy aimed at maintaining or increasing forest carbon stocks, while producing an annual sustained yield of timber, fibre, or energy from the forest, will generate the largest sustained mitigation benefit.“ A rational energy and environmental policy framework must be based on the premise that atmospheric greenhouse gas levels are increasing primarily because of the addition of geologic fossil fuel-based carbon into the carbon cycle. Forest carbon policy that builds on the scientific information summarized in this article can be a significant and important part of a comprehensive energy policy that provides for energy independence and carbon benefits while simultaneously providing clean water, wildlife habitat, recreation, and other uses and values.

This paper therefore encourages countries to implement REDD+ in a much more coordinated and holistic way in order to more effectively address the drivers of deforestation, however also highlights the potential socio-economic impacts of doing this and encourages policy makers to think more broadly than the forest dependent poor when thinking about equity in REDD+.

The REDD scheme of the United Nations Framework Convention on Climate Change is a carbon-based compensation for projects that resulted in reducing carbon emissions or enhancing carbon sinks or both in tropical forests. However, estimating such emissions and sinks remains challenging, and thus making it impossible to estimate carbon revenues from managing tropical forests. Here, we estimated the reduced emissions and sinks by developing models for setting Reference Emission Level (REL) and Project Emission Level (PEL) for REDD projects in concession forests taking emissions under conventional logging (CVL) scenario as that of REL, and emissions under reduced impact logging (RIL) and RIL with liberation treatment (RIL) scenarios as that of PEL. By choosing Cambodia as a case study, REL under the current logging system of 25-year cutting cycle was estimated at 23.1 TgCO2 year-1. To determine an appropriate cutting cycle, we tested our models with four cutting cycles and found that a 50-year cutting cycle is more appropriate. Taking this 50-year cutting cycle for REDD project, PELs were estimated at 0.4 TgCO2 and -3.3 TgCO2 year-1 under RIL and RIL, respectively (- means sinks). After subtracting REL with PEL and leakages, annual carbon credits from managing 3.4 million ha of concession forests in Cambodia were estimated at 15.9-18.5 TgCO2 depending on chosen scenario. With a carbon price of $5 MgCO2-1, total revenues from the sales of carbon credits alone are $79.5-92.5 million annually. To ensure continued flow of wood supply from tropical forests while mitigating climate change, we suggest that new climate agreements adopt RIL or RIL for sustainable forest management in tropical countries.

Unclear and/or insecure forest tenure has been identified by many as an indirect driver of deforestation and forest degradation. Consequently, reforming tenure is considered an important measure in order to control deforestation. Clarifying tenure is also seen as a way of promoting equitable REDD+ implementation. By clarifying tenure it will be harder for governments or powerful external actors to reap the benefits of REDD. Clear and secure tenure can also protect poor forest dwellers and local communities from exclusion or even eviction from forest lands and provide them with greater leverage in national REDD+ processes.

This paper describes specific ways in which the analysis of ecosystem goods and services can be included in terrestrial carbon sequestration assessments and planning. It specifically reviews the U.S. Geological Survey’s LandCarbon assessment methodology for ecosystem services. The report assumes that the biophysical analysis of co-effects should be designed to facilitate social evaluation. Accordingly, emphasis is placed on natural science strategies and outputs that complement subsequent economic and distributional analysis.

The FAO has released its ninth biennial report on the state of the world's forests. The report takes a holistic view by examining how forests support livelihoods in multiple ways.

* Agriculture is central to REDD+
When over 83% of new cropland areas in the tropical zone came at the expense of natural forests over the 1980-2000 period, and when the food challenge is becoming increasingly urgent, the REDD+ mechanism must find the means to tackle this sector of activity.
