Agricultural Value Chain Support Project, IFAD Impact Assessment Surveys 2017
Agricultural Survey [ag/oth]
The Agricultural Value Chain Support Project (PAFA) was designed to improve the livelihoods of smallholder farmers in Senegal’s groundnut basin. The main intervention, implemented through producer organizations, consisted of a comprehensive package of agricultural inputs, machinery, technical advice, and commercialization contracts with market operators. The project targeted vulnerable smallholder farmers, women, and underemployed youths.
The project is articulated around five components: (1) agricultural diversification and access to local market (2) development and structuring of regional value chains, (3) national coordination, knowledge management and project management, (4) climate change adaptation, and (5) support services for rural finance. The project was innovative in that, in addition to providing support to farmers through producer organisations (POs), there was an emphasis on improving concertation and collaboration around key value chains.

Given that the intervention was implemented at the PO (Producer Organization) level, a quantitative PO questionnaire as well as a detailed household questionnaire was administered to a sample of beneficiary and non-beneficiary PO members and leaders. A mixed-methods approach was used to determine the impact of the SPAM subsidy program.
Given the likelihood of spillover effects both within and across POs, the sampling strategy identified three groups in addition to the SPAM participants: 1. non-SPAM: members of PAFA POs who did not receive the SPAM (to measure the spillover within POs); 2. controls within: members of control POs in the regions of intervention; and 3. controls outside: members of control POs located outside of the regions of intervention.
Household-level data were collected from a sample of 2,233 rural households: 835 SPAM, 361 non-SPAM, 650 controls within, and 387 controls outside. Additionally, data were collected from 217 POs: 85 treated, 86 controls within PAFA regions, and 51 controls outside PAFA regions. An inverse probability weighting with regression adjustment (IPWRA) estimator was used to determine project impact.
This impact assessment fielded two survey instruments; the household questionnaire which contains information on household demographics, agricultural production, other income generating activities, and a shock/resilience module; and a PO-level questionnaire where a detailed account of PO activities, their institutional structure, crop production, level of market access, and constraints faced were recorded.
Using the data collected, the impact of PAFA was estimated on household-level indicators such as agricultural production, economic wellbeing, and resilience, and at the PO -level on market access, commercialization and asset levels, income and crop diversification.
Note: some variables may have missing labels. Please, refer to the questionnaire for more details.
