6. I.Background (4/5)
6
1. According to Statistics Act 7/96. 5 June, all agricultural
censuses are conducted by the INE in coordination with
the Ministry of Agriculture, while the agricultural surveys
are carried out by the Ministry of Agriculture under the
delegation of competences conferred by INE (National
Institute of Statistics).
2. Thus, the Ministry of Agriculture and Food Security,
since 2002 has been conducting annual agricultural
survey, with methodological supervision of the National
Institute of Statistics.

7. I.Background (5/5)
7
Since Independence in 1975, Mozambique has conducted two
Agricultural and Livestock Census:
1.In 1999-2000 (CAP 1999-2000) – questionnaire
2.The CAP 2009-2010 follows the modular approach of FAO taking
as common module, general data from Section G - Agriculture and
Livestock - from the III RGPH, which serves as sample frame for
Complementary Modules. And it was jointly with the Ministry of
Agricultural and Food Security
3.The III RGPH includes 10 of the 16 questions recommended by
FAO (WCA 2020) as part of the complementary modules of the
Agricultural Census

Themes
The annual agricultural survey is conducted every year
by MoA, except in the years of the agricultural census.

9. II.Implementation of the FAO Modular
Approach (2/2)

Six complementary modules were defined:
1. Crops,
2. Livestock,
3. Labour Force,
4. Aquaculture,
5. Food Security and
6. Agricultural Services and Practices

10. III. Sampling Frame
10
1. The sampling frame of CAP 2009-2010 was defined based
on information collected from the III RGPH. The
information refers to the identification and Section G
information – Agriculture, livestock and aquaculture;
2. For the six complementary modules it was designed a two
stage sample representative at district level;
3. First stage : enumeration areas (EA), were selected
systematically and with Probability Proportional to the
number of agriculture households in the EA;
4. Second stage: ten agriculture households were selected
randomly to be interviewed in each EA.

11. IV. Sample (1/2)
11
1. To produce reliable estimates at District level, 148 districts
(128 rural and 20 urban) the size pointed for the sample is :
2. 35 000 small farm households ;
3. All medium sized farms found in the selected enumeration
areas are surveyed (around 3000 expected)
4. Large farms are interviewed in a complete enumeration
basis (around 1000) in all country

12. 12
Class of holding
Land Area Cultivated Area Livestock
Large holdings 100 hectares OR 50 ha. of cultivated
land including both
annual and permanent
crops
OR 100 cattle OR 500 small
ruminants and pigs OR 10000 poultry
Medium holdings 25 hectares OR 10 ha. of cultivated
land including both
annual crops and
organized plantations
OR 5 ha. irrigated land
with annual crops
OR cattle
( >=10 & <100 ) OR small ruminants
and pigs (>=50 & <500) OR
poultry>=2000 &<10000
Small holdings Less than 25
hectares
AND less than 10 ha.
annual cultivation AND
less than 5 ha. irrigated
AND less than 10 cattle AND less
than 50 small ruminants and pigs
AND less than 2000 poultry
Classification of the holdings
IV. Sample (2/2)

13. V.Field Operations (1/5)
13
Cartography:
1.Widely used in the work of CAP.
2.In the rural EA the population can vary between 80 and 100 people,
and in urban EA the population can vary between 120 and 150 people
Selection and identification of the EA
1.The selected EA was identified based on the cartography maps.
2.To identify the limits of the selected EA the interviewers introduced
the coordinates in each map in the GPS.
3.After the identification of the boundaries of the EA, the brigade
does a listing of all households contained therein

14. V.Field Operations (2/5)
14
Training
Activity undertaken at different levels:
1.First level: central training of headquarters technicians
(Gabinete Central do CAP);
2.Second level: training of heads of provincial offices and
Supervisors;
3.Third level: training of candidates to interviewers in the
three regions (south, centre and north) – very important
to hire enumerators with IT skills.

15. V.Field Operations (3/5)
15
Data collection
Was done by mobile brigades.
81 brigades in all country
The brigade is composed:
1 Controller (head of the brigade),
3 Enumerators,
1 Driver
324 Enumerators in all country

16. V.Field Operations (4/5)
16
Consists of :
Listing, classification and selection of the agricultural household
(1 day) – manually
Interview (1 day) – by minicomputer
Data transmission – by net mobile (The Device Used for
Data Transmission)
Parcel measurement (½ day) – by GPS ( 2 meters accuracy)
Interviews

17. V.Field Operations (5/5)
17
1.Small Farms - 10 HS;
2.Medium farms -All HS classified as medium-sized farms
during the listing ;
3.Large farms – Complete enumeration in all country;
4.Measurement of parcels – two first households in each
EA (Enumeration Area) and all parcels were measured in
selected households.
Interviews

18. VI.Lessons Learned (1/3)
18
1. Before the Census of Population a mapping of EA was
conducted and a cartography database was defined. The size
and boundaries of enumeration areas were given by community
leaders however, in some cases the size was larger or smaller
than that defined for the purpose of the Census;
2. Lack of skills from the CAP 2009-2010 interviewers concerning
cartography, namely for reading maps and working with GPS;
3. Big teams during the training due to the Census schedule;
4. Delay in the beginning of data collection in South due to the
heavy administrative procedures related with the acquisition of
equipment namely vehicles, computers and GPS which caused
problems related with the movement of the equipment,
personnel and vehicles for Centre and North region

19. VI.Lessons Learned (2/3)
19
1. The solution was to involve more technicians to attend the
training mainly in the practical classes;
2. To avoid delays in chains in other regions, the solution was to
split the resources (central supervisors) and material resources
(vehicles) into the central and northern zones.
3. Join the adjacent area, if declared area is smaller and do the
listing again.
4. Split the area, if it was bigger than the one declared and do the
listing again.
Some Solutions found

20. VI.Lessons Learned (2/3)
20
Perspectives
1.For the next Census we will use the newly defined cartography
database, in which the size and boundaries of the enumeration areas
were made by the previously trained enumerators.
2.Mozambique will follow the methodological recommendations of
WC 2020 for next Agricultural CENSUS.
