Partnership in Statistics for Development in the
21
st
Century (PARIS21), shows how the increased
commitment on the part of external partners to
support statistics has been mostly directed to
economic and demographic statistics, with less
focus on environmental and agricultural statistics
(OECD, 2019). According to a recent report on
The
implementation of the Cape Town Global Action
Plan on Sustainable Development Data (World
Bank, UNSD and Paris21, 2022), two-thirds of NSOs
in International Development Association (IDA)
countries
12
experienced either moderate or severe
delays in budget disbursement in the last fiscal
year, which hampered the implementation of their
work programmes, and nearly 70 percent of them
prioritized the need to address funding shortages in
business and agricultural census programmes over
the next three years.
Solutions have been sought in exploring ways to
reduce the cost of data generation, for instance,
through increased reliance on secondary data
rather than collecting primary data, imposing,
however, additional requirements in terms
of analytic capacity to ensure that data from
different sources is integrated properly and avoid
compromising the quality of the data series and
comparability over time.
Another solution has been recourse to services
for data collection, analysis and dissemination
offered by private companies and professionals.
While useful to partially fill the data gaps,
such initiatives may raise various concerns, for
example regarding privacy, data access and data
governance.
13
Additionally, increased reliance
on private data services may further erode the
relevance and independence of NSOs.
A third solution, entailing the adoption of new
technologies for data generation and collection,
may certainly help (see more in Chapter 4).
However, new technologies usually require initial
investments and sustained support to ensure
that the technologies are effectively used. One
important aspect related to finance that has
prevented useful innovations from becoming
a permanent feature of data generation has
been the difficulty in securing stable funding to
keep the operations in place. When innovations
have been promoted through externally funded
projects, despite positive results, lack of
sustained funding has halted their large-scale
implementation.
In some cases, attempts to reduce costs to cope
with limited resources may have detrimental
consequences on data quality and relevance.
In sampling-based inferences, such as when
conducting farm or population surveys, or

conducting food-composition studies, one
way to reduce costs is by reducing sample
size, but these reduced samples may be too
small to produce indicators at the needed level
of precision. In other cases, particularly for
time-sensitive decisions, the need to secure
the necessary funding may delay the survey
operations to the extent that the usefulness
of the information they provide may be
compromised (
BOX 17
).
BOX 17:
THE HIGH COST OF FSN-RELEVANT SURVEYS
Population surveys that provide key information on respondents’ dietary intake and nutritional status may
require enumerators to perform individual nutrition assessment (collecting anthropometric, biochemical, clinical
assessment and dietary intake data). Training the enumerators and implementing the necessary field operation is a
costly and labour-intensive process.
Similarly, food production surveys that seek to reach small farmers and fishers in interior areas require the
mobilization of many enumerators over large distances, all of which increase overall survey costs. While newer
methods, such as the use of smartphones, may reduce the time spent in face-to-face data collection, and therefore
potentially reduce the number of needed enumerators, it is important to evaluate disparities in the ownership of
digital devices and access to technology and knowledge among the vulnerable group, including women and small
farmers.
In countries or even the regions with multiethnic populations, many languages are spoken and understood. This
adds a layer of complexity to the process of data collection (such as the validation of tools in different languages,
verifying the language competencies of the enumerators, etc.) and is expensive. When these demands arise in the
context of existing financial constraints, feasibility is usually prioritized over representativeness.
In many countries, the cost of validating dietary assessment tools, such as food-frequency questionnaires or
screeners with objective biomarkers, has been a major constraint and resulted in limited validation efforts.
This has often cast doubts on the quality of the data and, thus, on the validity of results arising from the dietary
surveys. Validation of self-reported dietary intakes, estimation of micronutrient intakes or levels of toxicity
require biochemical analysis. This is an expensive, resource-intensive process that requires elaborate logistical
arrangements, which are prohibitive in many projects. The lack of objective validation of dietary intake remains a
consistent challenge in interpreting dietary data.
Finally, dietary data needs further processing in terms of nutrient analysis. Such analysis, followed by the creation
of comprehensive food composition databases, is an expensive undertaking and unaffordable for many low-income
countries.
Inadequate research
infrastructure
Insufficient funding and the lack of well-trained
human capital also result in
inadequate research
infrastructure
at the national level to support
every stage of the data cycle (
FIGURE 2
). Beyond the
insufficiency of human and financial resources,
inadequate research infrastructure influences
how institutions set their priorities and actions
for research. Under-funded NSOs, overwhelmed
by competing priorities, tend to focus less on
food production statistics and certainly not (due
to underfunding and to a lack of capacity for
system thinking) on generating statistics from
across FSN-relevant sectors (agriculture, social
protection, health, industry and trade) or covering
the six dimensions of FSN. This is especially so in
[
51
52
]
DATA COLLECTION AND ANALYSIS TOOLS FOR FOOD SECURITY AND NUTRITION
developing countries where inadequate funding
further stresses organizational capability and
makes it necessary to prioritize just one aspect
of FSN. In such countries, the inadequacy of
research infrastructure is evident in the lack of
research quality frameworks and methodological
expertise for timely, relevant and sufficient data
collection and validation; lack of prior data; lack
of data processing and analysis capabilities;
and poor practices in data dissemination and
communication (Filter
et al., 2022; Jones et
al., 2017). Finally, infrastructure and resource
constraints also hinder
data-digitalization
efforts,
further limiting data availability and accessibility.
The lack of adequate modern data infrastructure,
especially in low-income countries, also limits
effective data collection, analysis and use. Due to
lack of access to broadband infrastructure in some
developing regions, such as Sub-Saharan Africa
and South Asia, where Internet usage gaps are as
high as 49 and 64 percent, respectively (Lishan and
Minges, 2018).
Social gradients
also influence
the placement of cellular and mobile services
and, thus, the penetration and quality of services
in remote areas. Social divides in digital access
and literacy is a further impediment to reaching
disadvantaged stakeholders, such as women in low
and middle-income countries and smallholders
(LeFevre
et al., 2021). Thus, while technological
advances may reduce costs and widen the reach
of surveys and help to fill some gaps in data
availability, the social divide may lead to the
underrepresentation of those with poorer digital
access and literacy (LeFevre
et al., 2021). This can
result in policies and interventions that are based
on data generated from skewed sampling, which
may not serve unrepresented stakeholders who
may have the greatest need for data-driven policy
and support (Bell
et al., 2017; LeFevre et al., 2021).
Therefore, the adoption of newer technologies
without considering the local context and the
impact of their use on users and beneficiaries can
further exacerbate inequalities, as illustrated in
boxes 18 to 21.

BOX 18:
THE COMPLEXITY OF NUTRITION ASSESSMENTS
Nutrition assessments
are a resource-intensive undertaking and, therefore, many of the constraints and bottlenecks
discussed in this chapter limit the complete range of assessments (including anthropometry, biochemical and
clinical and dietary intake). As previously mentioned, resource constraints can affect the availability of data and
capacity constraints can affect the quality of the data available. In particular, biochemical and clinical assessments
are resource-intensive and, therefore, multiple constraints acting in parallel result in a serious lack of data in this
regard.
An important domain of nutrition assessment is the accurate estimation of dietary intake in populations. Data in
this area are inconsistent, outdated, national food composition databases are incomplete, due to lack of support
for institutions involved in developing the databases; all these factors challenge the accuracy of nutrient intake
estimations in various countries and prevent their utilization by multiple users. The lack of comprehensive food
composition databases with adequate representation of both plant and animal, aquatic and land-based foods
consumed in the country, means that many countries rely on the databases of neighbouring countries or global
databases to estimate nutrient intakes. The use of inaccurate food composition data may lead to erroneous research
results, flawed policy decisions (particularly in nutrition, agriculture and health), misleading food labels, false health
claims and inadequate food choices (Charrondière, 2017).
The Malabo Montpellier Panel report (2017) clearly states that “African governments continue to lack the data
necessary to effectively combat malnutrition”, as “few national governments collect the data required to inform
decision makers about what people eat, and there is no functioning global dietary database.” (Malabo Montpellier
Panel, 2017, pp. 11–12). A recent review on global dietary surveillance (Micha et al., 2018) confirms the non-
availability or inadequacy of country-specific food composition tables (FCT) and food composition databases (FCDB)
as one of the major challenges linked to the limited availability of global dietary data which are needed for a wide
variety of purposes, including modelling, designing and implementing context-specific dietary policies to reduce
disease and disparities at national and regional levels. Strengthening regional collaboration and establishing
reference laboratories may provide a cost-effective solution. Another issue which must be tacked in nutrition
assessment, is the lack of representation of
indigenous and forest foods
in food composition databases. This hinders
the accurate evaluation of dietary intakes in indigenous populations (FAO, 2013a). INFOODS also tackles constraints
in paucity of food composition data.
BOX 19:
ON FOOD SAFETY DATA
Low- and middle-income countries often lack resources to invest in improving their own national food safety
regulatory frameworks and, therefore, rely on Codex standards as the basis for such legislation. However, Codex
standards may overlook practices that are common in small-scale food production and their connected value
chains (Humphrey, 2017). Both the European Food Safety Authority (EFSA) and Codex Alimentarius have databases
containing food safety parameters, but these are not available as open access. Food safety data, specifically, may be
regarded as sensitive to a country as levels above maximum limits can result in export bans and affect trade. Also,
financial and human resources for food safety monitoring programmes are major constraints in enabling timely and
relevant data collection related to food safety.

BOX 20:
THE WOMEN EMPOWERMENT IN AGRICULTURE INDEX
The Women’s Empowerment in Agriculture Index (WEAI) has been designed to track gender equality and the
transformation of gender norms (Malapit et al., 2019). The granularity of data allows for disaggregation by age-
group; gender; location; agroecological region; urban, peri-urban or rural residence; ethnicity and socioeconomic
and occupational class. This, in turn, also allows for in-depth understanding and targeted action. Sampling that
allows for such disaggregation along the food supply chain facilitates understanding of the contribution to food
production from both formal and informal sectors, and their disaggregated food consumption patterns. When
disseminated efficiently to the relevant stakeholders, this information can facilitate the involvement of the vulnerable
groups in decision-making and aid in their ownership of targeted initiatives. Such efforts are important to promote
equity in access to FSN data for policies and decisions at grassroot and local levels, taking into account local diversity
and context.
BOX 21:
SATELLITE TECHNOLOGIES FOR IMPROVED DROUGHT ASSESSMENT (SATIDA)
To improve reach, granularity and affordability in data collection, some countries have developed accessible digital
technologies for monitoring food security that help bridges many of the constraints referred to in this section,
improving the granularity of the data while applying a simple and affordable process. One such example is the
SATIDA (Satellite Technologies for Improved Drought Risk Assessment) project, which was developed to support
Doctors without Borders. At the regional and national levels, timely and granular data that allow for evaluation of
impact of innovative value-chain solutions and factors that can improve their uptake are also lacking (Committee on
World Food Security, 2021).
HUMAN RESOURCE CONSTRAINTS
The lack of adequate human capital within public
institutions responsible for FSN data generation,
curation and dissemination, is often cited as a
major constraint to data collection and analysis
in many countries. Human resources and staffing
have a huge impact on the availability of sufficient,
timely and high-quality data.
Constraints related to data
collection
The need for well-trained personnel in data
collection using traditional survey methods has
been acknowledged time and again (Krosnick,
Presser and Husbands, 2015). Dietary data
collection, for example, requires specific skills,
including the ability to select and properly use
the most appropriate dietary assessment data
collection instrument, to assist respondents
in estimating portion sizes, and to ensure
completeness of the reporting.
Although new technologies can facilitate data
collection, they do not eliminate the need for
considerable numbers of adequately trained
competent personnel (Aweke
et al., 2021).
Technology used to interview people from remote
locations, such as computer assisted telephone
interviews (CATI) or internet-based technologies,
might reduce the need for human resources, as
might automating some of the routine or time-
consuming tasks, but does not replace them
entirely. For example, reliable measurement of
certain outcomes, such as anthropometry and
the measurement of local food environments,
will always require the physical presence of
enumerators at the location. Furthermore,
harnessing the newer technologies to organize,
[
55
3
CONSTRAINTS, BOTTLENECKS (AND SOME SOLUTIONS) FOR EFFECTIVE USE OF FSN DATA
analyse and disseminate multidimensional data
usually requires technical skills that existing data
collection and analysis staff may not have. Effective
implementation of these technologies also
demands soft skills, including management and
leadership. The lack of these skills among existing
staff can collectively affect institutional capabilities
and arrangements for data processing, analysis
and dissemination. The training required to develop
these capabilities may be difficult to put in place
and take time, and this could limit or delay the
adoption and use of these new technologies (ILO,
2016, 2020).
While the importance of well-trained personnel
in data collection and analysis for FSN is
acknowledged, resource constraints make it
imperative to balance between the need for
specialization and the
sustainability of training
and capacity-building
efforts. Capacity-building
programmes such as those included under the
EAF-Nansen Programme, where students are
provided a stipend and trained in Norway with the
opportunity to collaborate with the host institution
upon return, is one example of a sustainable
capacity-building programme (
https://www.fao.
org/in-action/eaf-nansen/news-events/detail-
events/en/c/1309584/
). Many European Union
Funding Programmes also have consideration for
the sustainability of the capacity-building efforts
they fund. Despite these efforts, the sustainability
of capacity building is oftentimes challenged
by shortcomings in local environments, such
as lack of job opportunities, poor remuneration
and existing environments which do not provide
autonomy. This results in the brain-drain that
afflicts the Global South.
To address constraints in data analytical
capabilities, the FAO provides statistical support to
member countries. The success of these initiatives
is documented with countries in the Southeast
Asian Region have shown the highest gains in
terms of statistical competency over the last
decade (OECD, 2019). However, the ultimate impact
of the support provided to build capacity is limited
by the narrow assessment of capacity of national
statistical systems.
With reference to the challenges posed by the
diffusion of new technologies in agriculture, Florey,
Hellin and Balié (2020) highlight that:
1.
Many binding constraints faced by smallholder
farmers are associated with basic capacity issues.
For instance: smallholder farmers “are not
organized collectively, they have limited experience
of market negotiation, and little appreciation of
their capacity to influence the terms and conditions
upon which they engage with the market, and they
have little or no information on market conditions,
prices, and quality of goods (Shiferaw
et al., 2011).
2.
In geographies where markets for increased
inputs do not exist because the private sector
initiative and participation have not been
sufficiently stimulated (Ricker-Gilbert
et al., 2011;
Ghins
et al., 2017), pushing for higher-yielding
technologies (such as modern crop varieties) to
increase productivity merely ensures that input
prices can be more readily controlled by the low
number of agro-dealers. As a result, the market
power exercised by too few operators will lead to
depressed farm-gate prices because of continuing
high input prices.
3.
There are many farmers for whom increasing
productivity and greater access to markets are
not a priority, instead, they focus on off-farm or
non-farm activities with a view to temporarily or
permanently exiting from farming (Mausch
et al.,
2018).
Constraints related to the lack of
data processing, analytical and
dissemination capabilities
The reliability and availability of FSN data are
often limited due to (i) lack of capabilities in
data processing and analysis and (ii) lack of data
analytical capabilities.
The analysis of dietary assessment data, for
example, requires specific skills, such as the
ability to choose an appropriate food composition
table given the list and detail of dietary intake
data and the ability to match food listed in food
composition databases with the description of food
DATA COLLECTION AND ANALYSIS TOOLS FOR FOOD SECURITY AND NUTRITION
items included in the data collected, even when
there is no perfect match. Similar considerations
can be made with respect to the analysis of food
security data from surveys. For instance, in the
initial implementation of the FIES food insecurity
in survey tool, FIES data was collected in a large
number of surveys throughout the world before
a sufficient number of trained analysts had the
time to acquire the necessary analytic skills to
process the data properly, especially in low- and
lower middle-income countries. Consequently,
various reports were produced in which results
were misleading, as they were based on incorrect
assumptions made during analysis.
Concrete examples of how processing capabilities
affect the quality of dietary data are seen in
performing dietary intake assessment, food
composition analysis and biomarker assessments
relating to micronutrient intake and food toxicity
assessments. To facilitate data processing and
analyses, various automated procedures have been
proposed, which presents opportunities, but also
risks (
SEE BOX 22
).
BOX 22:
OPPORTUNITIES AND RISKS IN THE USE OF AUTOMATED DATA ANALYSIS
Recent technological advances in dietary assessment have integrated the various steps in dietary analysis,
using dietary analysis platforms that have offline and online capabilities (
https://www.fao.org/infoods/infoods/
software-tools/en/
). This reduces the potential for errors arising from manual data entry and its subsequent
transcription. However, many of these software that allow for modular usage of local food composition databases
are not open-access, and their lack of affordability limits widespread uptake in low- and middle-income countries.
Another limitation is that they require capabilities in the appropriate use of food coding in dietary intake analysis.
Standardizing data coding as part of quality assurance and data processing is another important step that may not
be properly addressed owing to lack of expertise, specifically when quality research frameworks do not exist. For
instance, standardization of food coding is an important step in dietary analysis that matches foods in the dietary
assessment obtained with foods in the nutrient database. As diets are complex and the variety of foods consumed is
greater than those reflected in the food database, matching of foods is challenging and requires expertise, including
knowledge of the local cuisine. Additionally, foods consumed simultaneously, like coffee with milk, are given codes
that identify these recurring combinations. The combination codes, when appropriately used in the database can
aid holistic dietary pattern and quality analysis and reveal more visible and accountable patterns that may impact
nutrition security and health (Mason et al., 2015).
An attempt by the European Food Safety Authority (EFSA) to provide a common link to data sources across different
food safety domains is the FoodEx2 project (Nikolic and Ioannidou, 2021). FoodEx2 provides descriptions of a large
number of individual food items aggregated by food groups and broader food categories within a hierarchical
structure. The Food Ex2 facet descriptors included in the classification system are also mapped to national food
composition database compilers from 14 European countries. This expands the dataset to include harmonised
information on the most common composite recipes of European countries and harmonised information on food
supplements and provides an updated food composition database with over 1 750 foods (Roe et al., 2013).
56
]
Apart from the data processing abilities, several
constraints related to analytical capabilities have
been identified in FSN areas. Analytical challenges
can involve deficiencies in data measurement
capabilities (measurement techniques, independent
from human resources training) or insufficient
capabilities in data analysis based on limitations
in computing software. One example with regards
to lack of analytical capabilities is the challenges
faced in assessing dietary biomarkers. While the
use of dietary biomarkers improves the accuracy
of dietary intake estimations, its implementation
[
57
3
CONSTRAINTS, BOTTLENECKS (AND SOME SOLUTIONS) FOR EFFECTIVE USE OF FSN DATA
requires extensive sample collection, storage,
transportation, processing and analytical abilities.
Micronutrients and toxicity analysis in food require
sophisticated laboratory equipment and related
methods that are prohibitively expensive to the
LMICs. This lack of food and biochemical analytical
capabilities results in incomplete nutrient lists in
the food composition tables of many countries.
A related constraint is the insufficient
data
analytic capacity
(that is, powerful computers)
needed to process large amounts of available
data and information. The collection and use of
multidimensional big data sets also introduces
complexities that may require upskilling of the
current staff.
Insufficient capacity to effectively disseminate,
interpret and communicate data limits the utility of
the data and hinders advocacy efforts for continued
investment in FSN-related data collection. After
data collection and analysis, results are often
communicated only in the form of tabulated data,
with relatively
little interpretation and analysis
(FAO, 2015; OECD, 2019). While awareness is
growing of the importance of supporting data
use with proper analytical briefing on how the
data are obtained from elementary information
(Hicks
et al., 2019; Vaitla et al., 2018; Sethi and
Prakash, 2018), the lack of such products can
hamper data-informed policymaking and targeted
interventions to address the problem (FAO, 2015).
Moreover, skills restricted strictly to statistical
domains may be insufficient with the emergence
of advanced technologies in data production
with increased complexity, and the involvement
of new data providers and users. There is also
a lack of emphasis on data communication and
dissemination. Additionally, lack of availability of
the information in local languages hinders data
utilization by creating language barriers. Given
that too few NSOs in developing countries monitor
the use of their data (Sethi and Prakash, 2018), it
is difficult to gauge the actual utility of the data.
It is important to obtain this data and estimate
bottlenecks that prevent effective data usage to
strategize remedial measures.
INADEQUATE INSTITUTIONAL
ARRANGEMENT AND DATA
GOVERNANCE
This section describes issues relating to data
governance that arise from the lack of stakeholder
engagement, lack of coordination among agencies
and lack of transparency and appropriate
regulatory frameworks.
CONSTRAINTS THAT LIMIT
STAKEHOLDER ENGAGEMENT
The usability of data is limited when stakeholders
have not been involved in the survey planning
and there is inadequate dissemination or access
to information on what data are available and
how they can be used by the stakeholder. These
constraints to the access and use of data for
improved decision-making make it difficult to
advocate for further funding and commitments
towards the collection and analysis of FSN data.
Specific concerns with regards to
human rights
and privacy
arise when stakeholders are not
involved in the collection of data, specifically among
vulnerable populations, including indigenous
populations. (These issues are discussed in detail
in Chapter 5). Adequate representation of diversity
and inclusion of minorities and the ability to
disaggregate data for specific populations are also
closely related to lack of stakeholder engagement
and the limitation this poses to the utility of the data
in decision-making in these contexts. Inadequate
