• Availability:
§ Data

A

from
the
“Evidence

Analyses”
• Various
climate

effects
over

and
nega&ve
rela&on

• Posi&ve
associa&on
with
the
adop&on
of
adapta&on
prac&ces
(benefits
on
both
crop
yields
and
food
security
–
resilience);
• Higher
profitability
due
to
adop&on
of

prac&ces
than
to
use
conven&onal
&llage
(yields,
gross

Suitability
of
household
data
• Na&onal
household
surveys
do
not
necessarily
include
most
of
the
mi&ga&on-‐relevant
ques&ons.
• Mi&ga&on
issues
are
understandably
not
the
first
priority
of
the
data
collec&on
efforts
-‐
main
objec&ve
is
to
provide
and
update
sta&s&cs
in
MW
on
poverty,
health,
educa&on,
food
security
and
welfare.
• But:
High

between
climate

to

(star&ng

• This
includes
mainly:
– Adop&on

– Management

– Detailed

– Use

Conclusion
• Na&onal
representa&ve
household
data
provides
following:
– May
importantly
improve
the
data
quality
from
agricultural
ac&vi&es
where
na&onal
representa&ve
data
is
not
yet
used;
– Allows
to
ship
from
using
na&onal
aggregated
data
to
more
plot
specific
es&ma&ons
(Tier
2);
and
– Allows
to
consider
further
sources
of
GHG
fluxes
that
are
currently
not
considered
in
repor&ng
(e.g.
soil
and
grassland
carbon
dynamics)
• EPIC
project
inten&on:
– Deriving
approximate
mi&ga&on
poten&als
for
future
ac&on;
and
– The
proposal
outlined
here
for
possible
combina&on
of
household
data
&
Tier
2
methodology
for
na&onal
es&ma&ons
as
a
secondary
outcome.
• The
presented
methodology
for
soil
carbon
and
nitrous
oxide
is
an
ini&al
approach
that
will
certainly
need
refinement
at
a
later
stage.
• Tier
2
es&ma&ons
should
be
validated
with
targeted
field
measurements.

• What
is
the
availability
of

survey
data
in
your
country?
– Representa&ve
at

– Containing

• Cropland

• Land

• Agroforestry
tree

• How
do
you
currently
collect
and
aggregate
data
for
na&onal

– Na&onal
representa&ve?
Specificity
of
informa&on
(see

• Are
there
ini&a&ves
that
intend
to
establish

for
the
agricultural
sector
(e.g.
NAMA)?
Which
methodology
do
