Low
emissions
agriculture:
Suppor3ng
agricultural
development
that
GHG
emissions
or
sequesters
carbon.

What
it
does
-­‐ Es3mate
GHG
emissions
for
different
land
use
systems
according
to
management
types;
-­‐ Rank
the
most
effec3ve
mi3ga3on
op3ons;
-­‐ Es3mate
the
mi3ga3on
poten3al
of
different
op3ons.
What
it
does
not
do
-­‐
Es3mate
life
cycle
assessment
of
GHG
emissions;
-­‐
Scale
emissions
up
to
total
area,
total

-­‐
Es3mate
GHG
emissions
in
different
microclimates;
-­‐ ….

Main

-­‐ It

-­‐ Quick

-­‐ General

sources
-­‐ Tool
to

providing

-­‐ Accommodates
regional
differences

GHG
emissions:
main
input
variables
are
flexible
• Region,
climate,
soil
characteris;cs
• Ecosystem:
upland
(34
crops
+
other),
rice,
grassland
• Current
management
prac;ces:
user
can
choose
which
prac3ces
they
are
using
(e.g.
fer3liser
applica3on
rate,
3llage
prac3ces).
