Agricultural Survey [ag/oth]
The Annual Agricultural Survey (EAA) is a sample survey carried out during the main agricultural season in Senegal (July of year n to June of year n+1) with the primary objective of providing information on main rain-fed agricultural production in Senegal. The adoption of the modular approach of the AGRIS method, since the 2017-2018 agricultural campaign, has improved the coverage of the survey by taking into account non-rainfed activities (livestock, horticulture, fishing/aquaculture and agroforestry) of agricultural households and the integration of the technical, economic, environmental and social dimensions of agricultural holdings.
The agricultural survey in its current form covers all regions of the country and all 45 departments of Senegal. The agricultural survey is an annual statistical operation whose general objective is to estimate the level of the main agricultural output of family-type agricultural holdings. It also makes it possible to provide information on the physical characteristics of cultivated plots (geo-location, area) and major investments made at their level (agricultural inputs, cultivation operations, soil management and restoration). The main indicators relate to yield levels, areas sown, production and means of production.
Following a modular approach, the 2021-2022 edition of the EAA is characterized by the integration of the ILP (Revenue, Labor and Productivity) module. The introduction of this module makes it possible to collect the information necessary for the calculation of SDGs 2.3.1 and 2.3.2. In addition, the basic module of the 50x2030 questionnaire allows the collection of data for the calculation of SDG 5.a.1 and CAADP indicators (3.1i, 3.1ii, 3.2i, 3.2ii, 3.2iii and 4.1i) .
Sample survey data [ssd]
Households
Scope
The description of scope includes:
- Socio-demographic characteristics of agricultural households
- Characteristics of agricultural holdings
- Agricultural production methods
- Cultivation activities of households
- Use of agricultural inputs and equipment
- Production and use of vegetable crops
- Livestock
- Agricultural labour force
- Fisheries and aquaculture
- Agroforestry
- Production-related shocks
- Subsidies, loans and transfers
- Average labor productivity (SDG 2.3.1) and average income of small-scale agricultural producers (SDG 2.3.2)
- Ownership of land, especially in women (SDG 5.a.1)
Coverage
The annual agricultural survey covers all 45 departments of Senegal. However, for reasons related to anonymization, the variable "Department" has been replaced by the variable "Agroecological Zone" which constitutes groupings in relation to the departments. The variable "Region" remains in the anonymized version of the data.
The agricultural survey covers all households and plots in the 45 departments of Senegal.

Sampling
The EAA was built on a two-stage survey, with enumeration districts (DRs) as primary units (PU) and agricultural households as secondary units (US), as defined during the general census of population and l'Habitat, de l'Agriculture et de l'Élevage (RGPHAE) of 2013. In line with the broadening of the scope of the survey recommended by the AGRIS approach, the sampling plan has integrated from this campaign , a first-degree stratification, induced by that of the second degree, to better reflect the different agricultural activities and improve the efficiency of the estimates. The choice of a first-degree stratification induced by that of the second degree, although less efficient than an independent first-degree stratification. The stratification took into account the relative importance of the main agricultural activities (in terms of household size) identified during the 2013 RGPHAE, namely rainfed agriculture, livestock and horticulture.
Four strata were thus formed as follows:
- the “rain-fed only” stratum which groups together all the households practicing only rain-fed crops;
- the “livestock only” stratum for households that practice animal husbandry only;
- the “Horticulture and other crops” stratum, which includes households that mainly practice horticulture and secondarily other crops (forestry, fruit growing, etc.);
- the “Rain-fed-breeding” stratum made up of households that practice both rain-fed agriculture and livestock breeding.
The size of the sample of agricultural households to be surveyed was calculated by department (area of study) by setting a relative error of 10% on the variable of interest. The distribution of the sample of each department in the strata was made using the method of Bankier (1988) developed in the methodological guide on the Practices of Master Sampling Bases (pp. 79-81) of the Global Strategy (GSARS ).
At the national level, the total theoretical sample is equal to 7,450 households, spread over 1,460 physical CDs, with 5 households per CD. At the end of the enumeration operation carried out in the physical sample CDs, adjustments were made to take into account the actual updated size of the CDs, which led to a final size of 7,378 households, or 1,382 CDs.
The overall response rate is 94% for the first phase of the survey while it is 89% for the second phase.

Survey instrument
The first questionnaire collected information on census and characteristics of agricultural household plots. The second questionnaire collected information on agricultural production, labor and agricultural productivity.
The microdata contains information on households and individuals and therefore were anonymized before dissemination for analysis.

- Computer Assisted Personal Interview [capi]
At the regional level, of which there are 14 for all regions, the regional supervisors (the person in charge of statistics at the DRDR level if the position is filled) are responsible for:
- supervising the selection of interviewers and the refresher sessions;
- receive and distribute survey material (training materials, tablets / smartphones, supplemental questionnaires, fuel supply, etc.);
- facilitate the centralization of equipment (smartphones, chargers, etc.) at the regional level at the end of operations;
- supervise the consolidation of the data collected (verification, consistency, etc.);
- inform regional and national authorities on the implementation of operations.
At the departmental level, there are 45 departmental supervisors (Departmental Heads of Service), who are responsible for:
- to assist the regional supervisor in his tasks;
- supervise the preparation and implementation of the survey plan;
- proceed with the allocations of CDs and households;
- facilitate the control and correction of data;
- to save the data (files) in a computer;
- participate in the consolidation of data at the regional level;
- to ensure proper management of equipment.
The 45 departmental supervisors are responsible for:
- assisting the departmental supervisor in his/her tasks;
- implement the survey plan;
- to control the collection operations in the field;
- make corrective proposals on collection operations (observation points, collection devices, etc.).
The 168 investigators are responsible for:
- informing the local authorities of the operation;
- identify the household to be surveyed with the support of the authority;
- administer the various questionnaires;
- submit the questionnaires to the supervisor for approval;
- to approach the controller for checking, correcting and saving the data (saving in the controller's/supervisor's computer on each occasion to prevent data loss).
