This might seem just an accounting fiction, except that lagged transactions between forests, their products and CO2 sinks mean that a single forestry cycle leads to higher atmospheric CO2, two or three decades after final felling, compared with the "no-afforestation" base-line.
The potential afforestation map is based on the net primary production map for Europe derived from remotely sensed MODIS (Moderate-Resolution Imaging Spectroradiometer) products, precipitation and temperature conditions from the Wordclim database and soil conditions from the International Institute for Applied Systems Analysis.

The model is based mainly on the global afforestation model of [4] and calculates the net present value of forestry with equation (1 – 16) and the net present value of agriculture with equation (17 – 20).

Soil nutrient contents were higher in afforested lands and increased with afforestation age.
These base investment returns in 2011, excluding land costs, favour afforestation in South American countries, which have fast growth rates and reasonable timber prices.
This exploration was done through a scenario study based on a spatially explicit empirical model of spontaneous afforestation in relation to several physical landscape and policy relevant variables.

To calculate potential soil organic carbon if the landscape was forested, we used soil organic matter from soil surveys of the agricultural landscape, and multiplied the carbon by a factors of 1.25, 1.5, and 1.75 based on published reports of soil carbon increases due to afforestation.
The afforestation process is modeled as an ecosystem simulation, where trees struggle for survival based on several growth factors.
