Agriculture Integrated Survey [hh/nhh/agris]
The 2024 Sierra Leone Annual Agricultural Survey (AAS) is the second round of AAS conducted in Sierra Leone. It was implemented under the 50x2030 Initiative, a program jointly launched by the World Bank, Food and Agriculture Organization of the United Nations (FAO) and International Fund for Agricultural Development (IFAD). The lead national implementing agencies in Sierra Leone are Statistics Sierra Leone (Stats SL) and the Ministry of Agriculture and Food Security (MAFS).
AAS was designed to ensure the production of foundational agricultural data that are timely and of quality, fit the needs of the country and match the main national development targets. The approach adopted is that of a modular approach. This second survey round cover the CORE survey with additional focus on the Production Methods and Environment (PME) module.
The Sierra Leone Annual Agricultural Survey (SLAAS) is a key component of Stats SL's efforts to provide up-to-date information on the agricultural sector. The SLAAS program follows the AGRIS methodology, an integrated approach that combines a core questionnaire with rotating thematic modules to capture the technical, economic, environmental, and social dimensions of agricultural holdings. In 2024, the Production Methods and Environment (PME) module was adopted, enriching the core survey with detailed data on irrigation, energy use, land management, rice cultivation, livestock breeding strategies, environmental strategies and adaptation to climate change which are important in identifying and quantifying the gaps that exist and capitalizing on specific interventions that address these gaps.
The overall objective of the SLAAS was to collect comprehensive data on crop and livestock production, as well as other relevant agricultural indicators. This information is essential for policymakers, researchers, and other stakeholders to assess the performance of the agricultural sector, identify opportunities for improvement, and inform evidence-based interventions.
The specific objectives of the SLAAS 2024 include:
- To collect disaggregated and timely data on agricultural production and productivity at both national, regional and district levels.
- To produce baseline and monitoring data that supports the formulation, implementation and evaluation of agricultural policies and programs.
- To generate consistent and comparable agricultural statistics for assessing trends, informing budget allocations, and facilitating investment in the sector.
- To compile fundamental statistics that facilitate comparisons in the development of the agriculture sector across the country.
- To collect key data necessary to assess the impact of agricultural activities on the environmental, social and economic sustainability of farming.

Scope
This survey collected data from agricultural households, covering the Post Planting (PP) season and the Post Harvesting (PH) season. The topics covered are: characteristics of agricultural households, agricultural production (crops, livestock, aquaculture, fisheries and forestry), input use, labor force, land use, energy use and environmental issues.

Coverage
National coverage, with the exception of the Western Urban district
The survey covered agricultural households engaged in crop production, livestock rearing, fishing and aquaculture, and forestry production regardless of their scale of operation.

Sampling
A two-stage sampling method was employed to select households. Both stages of sampling employed probabilistic methods.
The country was divided into districts and within each district, areas called Enumeration Areas (EAs) were identified. A sample of EAs was then selected, followed by a sample of agricultural households (Ag HHs) within each chosen EA. A total number of 520 EAs were selected as Primary Sampling Units (PSUs), out of which 5200 households were selected as Secondary Sampling Units (SSUs).
Due to operational constraints, not all sampled households were successfully surveyed during data collection. In total, only 518 EAs and 5110 households were actually covered during the survey. Consequently, the PP phase comprised 4,998 households. Additionally, survey attrition occurred during the PH phase. Weight variables for each phase have been adjusted to account for these variations.
Sample weights were calculated for the data files computed as the inverse of the probability of selection of agricultural household, which is the product of the probability of selection of the EA in which the household is located (at the first stage) and the probability of selection of the household (at the second stage).
The weight variable in both visits is called "HH_Final_weight". Users should note that the PH weight was adjusted from the PP weight to account for differences in household coverage due to deviations in the sampling design and some decisions taken during the data cleaning process.
Survey instrument
For this survey, two (02) questionnaires were used: the Post Planting (PP) questionnaire and the Post Harvesting (PH) questionnaire.
They were administered in each household, preferably to the head of household. They cover two (02) modules, the CORE module and the PME (Production Methods and Environment) module, split into several topics such as household demographics, agricultural production (crop, livestock, fishing and aquaculture, forestry), input use and labour, land use, energy use and environmental issues.
The questionnaires are provided as external resources.

The teams of data collectors were divided into two groups: enumerators, primarily responsible for collecting data from eligible and consenting households, and supervisors, responsible for assigning and assisting enumerators in solving problems that they may encounter during the administration of the survey questionnaire and reviewing each questionnaire before it is submitted.
The data of the SLAAS 2024 was collected throughout the annual agricultural period. This period is divided into two seasons: the first season gave rise to the first phase of the data collection, corresponding to the Post Planting (PP) phase, and the second season gave rise to the second phase of the data collection, corresponding to the Post Harvesting (PH) phase.
A training of enumerators was held before each phase. During the training, the questionnaires were presented and tested, and the main roles of each team member were discussed and elaborated.
Data processing
The PP and PH questionnaire were implemented on CSPRO as CAPI tool. During data collection, some validation controls were integrated into the app to minimize mistakes when typing households’ answers. After data collection, a processing program designed under SPSS software permitted to clean both cases and variables. Duplicated cases were deleted and then the sampling weights adjusted to take the two non-covered EAs into account. Missing, not allowed, unalike and incoherent values were detected and then locally imputed objectively in respecting filters. Finally, the necessary tabulation variables were created and then tables were produced according to the tabulation plan designed earlier.
Data appraisal
To appreciate the data quality, some tables were supported by sampling errors estimates. Especially, coefficients of variations and standard errors were estimated for a set of indicators for open data publishing purposes.
