2. Market
prices

3. Data on market prices
Many agencies – including NBS, the Central Bank
of Nigeria, NPFS, the Abuja Commodity
Exchange, the Famine Early Warning System
Network (FEWS NET), State statistical bureaus,
ADPs and NAERLS – collect market price data for
different commodities, on different markets and
with different frequencies; the agencies employ
a varied set of tools, methodologies and
specifications.

4. Market prices
Market price data from the NPFS were accessible
through its NAMIS Bulletin; thus, they were not up-
to-date. The NAERLS also publishes its data, on a
very limited number of market prices, in
newspapers and through sponsored radio
programmes. FEWS NET and the Abuja Commodity
Exchange also publish their market prices on their
websites. The NBS’ Consumer Price Index (CPI)
reports are available on its website, while its data
on market prices are also available on demand.

6. Data on stocks
FMARD (through the Department of SGR) is the
custodian of the national grain reserve. Grain
stocks may be available on farms and private
commercial firms, although structured data
sources for these stocks are unavailable. NAERLS
appears to collect data on available stocks of
food commodities, from both Government silos
and state-owned warehouses.

7. Stocks
For agricultural stocks, the SGR is responsible for
data on buffer stocks at the state level; where
such stocks exist, the data can be provided on
demand. However, there is no clear policy to
guarantee easy access to data on a regular basis.
Some of the data is also withheld for national
security concerns.

9. Data on crop production forecasts
Data on crop production forecasts are only produced by
the National Agricultural Extension Research Liaison
Services (NAERLS). Crop production estimates are
generated by different government agencies, including
the National Bureau of Statistics (NBS), the National
Programme for Food Security (NPFS), and the Planning
Research and Statistics Department (PRSD). The NPFS
conducts the APS/Farm Output Survey and recently,
under its General Household Survey (GHS) Panel, collects
data on agriculture, including upon area cultivated and
production obtained, reporting the relevant data at the
national level. In particular, data on wheat forecasts is
absent.

10. Crop production forecasts and
production estimates
Data produced by NAELS on crop production
forecasts is accessible mainly by contacting the
agency itself. The agency’s publications on the
survey results are only provided to
governmental organizations and other partners.
Although the agency has a website, it is very
difficult to access and the data are not always
available.

12. • Search in SDMX Registries, what can you
reuse?
• Do you want many DSDs, or as little as
possible?
• What did you not find, e.g. for which artefact
Nigeria will maintain one for itself?
