Sustainable Land Use and Forestry

| Forest/mountain range in Bolivia. |
The surface temperature of the earth is warming and concentrations of greenhouse gases (GHGs),
especially carbon dioxide, have increased substantially since the beginning of the Industrial
revolution. The National Academy of Sciences indicates this increase is due in large part to human
activity, and in its report concludes that significant areas of uncertainty remain, including how much
effect natural fluctuations in climate may have had on warming, how fast climate changes will occur,
the magnitude of those changes, and their impacts. As human populations and economies grow, many of
which are currently highly dependent on carbon-based fossil fuels, GHG emissions will also likely rise.
Since climate change affects the global environment, human populations, and economic development, the
challenge to the global community is to further economic development while also limiting the associated
growth in GHG emissions.
