Q

is defined as the process of capturing carbon from the atmosphere so that the buildup of carbon dioxide (the principal greenhouse gas) concentration will be reduced

A

Carbon sequestration

21
Q

defined by Watson et al. as an anthropogenic intervention designed to reduce the emissions or to enhance the sinks to greenhouse gases.

A

Climate change mitigation

22
Q

defined as interventions to minimize the impact of climate change to those likely to be affected by this phenomenon.

A

Climate change adaptation

Q

In forestry, there are so many C assessment tools now a days and they all started from this concept ____________________.

A

“A tree is 50% carbon”

25
By composition wood is _____ Carbon, ______ Oxygen, ____ Hydrogen and ____ Nitrogen
50%; 42%; 6%; 1%
26
___________________ is the amount of GHG often measured using CO2 equivalent.
Greenhouse gas emission
27
A ______________________ is a tool that can provide historical information of the anthropogenic GHG emission sources and removals within a certain area
GHG emission inventory or accounting
