Data collection and analysis tools for food security and nutritionParticular fundamental areas of FSN where lackcc1865en Particular fundamental areas of FSN where lack
of sufficient data is especially relevant include,
the impact of pests, natural calamities, conflicts
or other shocks on food security and nutrition.
(
SEE BOX 8
).
Another area where granularity of data is
crucial is that of meteorological and soil fertility
data. These data have important implications
for drought monitoring and early warning
regarding possible risks to local food availability.
When meteorological data are available, those
derived from ground-based stations may record
variables such as rainfall, temperature and
wind, but not more technical measures such
as humidity and solar radiation. This may lead
to significant data gaps and inaccuracy. Earth
Observation (EO) climate data products, based
on broad hydrometeorological monitoring tools
such as Global Land Data Assimilation System
(GLDAS), can fill gaps by substituting missing
data and generating data sets (Colston
et al.,
2018). However, these data disaggregated by
agroecological zones are largely lacking.
Overall, this is an area where more granular,
georeferenced data collected through different
means and technologies (such as the
Google
earth engine
), holds great promise (see further
discussion of technologies in Chapter 4).
FSN DATA AND INFORMATION AT THE
MESO (PROXIMAL) LEVEL
The structure of the agriculture, food, health and
other related sectors have strong implications
for food security and nutrition. National food
and agricultural data (on food supplies, prices
and inflation, for instance) and the structure of
national food supply chains, among other factors,
shape the social and economic environment in
which citizens live and operate and are vital to
inform most dimensions of food security at the
meso level, including availability, access, stability
and sustainability. Ideally, such data should be
included in national official statistics, regulated
in most countries by national statistical laws and
coordinated by national statistical offices (NSOs).
Despite efforts, there are still gaps and notable
differences among countries in this regard. The
timeliness, completeness and quality of official
statistics on agriculture, fisheries and other sectors
of relevance to food security and nutrition, is still
largely insufficient in many low- and middle-
income countries (LMICs). According to the latest
FAO assessment for example, 92 countries have
not conducted an agricultural census in the last
ten years, 52 of which have not done so in the
last 20 years (
ANNEX TABLE 3
). Ten of these countries
(including Cuba, Ukraine and South Sudan) have
no agricultural census on record at all. This is
