Strengthening rural women farmers through organized agricultural extension training: A socioeconomic impact study

Introduction

Across sub-Saharan Africa, women cultivate a majority of the food consumed locally, yet they access only a fraction of available agricultural advisory services. This systemic exclusion carries significant economic consequences. According to the Food and Agriculture Organization, eliminating the gender gap in agricultural inputs and services could boost crop production by 20-30% in many developing nations [1] . Notwithstanding this well-established potential, most advisory systems persist in treating rural women as incidental rather than priority beneficiaries of extension programming [2] . The extension landscape in Nigeria mirrors this broader inequity. Women make up approximately 60-80% of the farming workforce in the southwestern zones, undertaking planting, weeding, harvesting, and post-harvest activities on most smallholder plots [3] . Yet their rate of contact with extension agents falls well below that of men-owing in part to restrictions on mobility, cultural expectations regarding gender roles, and conflicts between domestic duties and training schedules [4] . Organized training interventions that confront these obstacles have demonstrated potential in Eastern African pilot programs, but thorough evaluations from West African settings remain rare [5] . This study assessed the socioeconomic effects of an organized seven-module extension training program designed specifically for rural women farmers in Ogun and Ekiti States, southwestern Nigeria. The research contrasted outcomes for women enrolled in the training against a matched comparison group receiving standard advisory visits over a 20-month duration [6,7] .

Material and methods

Research area description

The study was carried out in Ogun and Ekiti States in southwestern Nigeria. Four local government areas (LGAs) were chosen-Abeokuta South and Ifo in Ogun State, and Ado-Ekiti and Ijero in Ekiti State. These LGAs were selected because they contained active women farmer associations registered with the state Agricultural Development Programs and had not been exposed to any specialized gender-targeted extension training in the preceding three years. The area falls within the tropical forest-savanna transition belt receiving 1,100-1,400 mm annual rainfall, supporting mixed arable and tree crop production [8] .

Material

A pre-post quasi-experimental design was used with treatment and comparison groups. The treatment group consisted of 228 women farmers drawn from registered women farmer associations across the four LGAs. The comparison group comprised 206 women from adjacent communities who received only routine extension contacts. The intervention was an organized seven-module training program covering advanced crop management, household financial planning, market linkage strategies, cooperative leadership, input sourcing, and post-harvest loss reduction. Modules were delivered biweekly over seven months through participatory sessions and on-farm demonstrations. Data were gathered at baseline (February 2021), midpoint (November 2021), and endline (September 2022) using structured survey instruments.

Methods

Socioeconomic outcomes were assessed across four dimensions: seasonal earnings (self-reported farm income), crop output (yield estimates for cassava and vegetables), nutritional security (Household Food Insecurity Access Scale adapted for individual-level measurement), and decision-making autonomy (share of household farming decisions in which women reported active involvement). Quantitative data were analyzed using paired t-tests for within-group changes and independent t-tests for betweengroup differences. Effect sizes were computed using Cohen's d. Ethical approval was secured from the Institutional Review Board of Ibadan College of Agricultural Extension and Rural Sociology (Protocol No. ICAERS-IRB-2020-089, approved November 2020).

Ethical considerations

Ethical approval was granted under Protocol No. ICAERS-IRB-2020-089 in November 2020. State-level authorization was obtained from the Agricultural Development Programs of Ogun and Ekiti States. Written informed consent was obtained from all participants in English and Yoruba. Participation was voluntary and confidential. Special attention was given to conducting sessions at times and locations convenient for women with domestic responsibilities.

Results

Table 1 presents baseline characteristics. The intervention and control groups were comparable in mean age (37.8 vs 38.6 years), household size (5.5 vs 5.1), and farm area (0.86 vs 0.81 ha). Literacy rates were similar (intervention 49.3%, control 46.2%). Figure 1 shows the relationship between number of extension sessions attended and percentage income change among intervention participants. Figure 2 presents the capacity building framework showing the six intervention modules and their pathways to socioeconomic outcomes. Women who attended 14 or more sessions (roughly 72% of the full program) showed significantly larger gains across all indicators than those attending fewer sessions, suggesting a dose-response relationship between program engagement and outcomes.

Comprehensive interpretation

The intervention produced consistent gains across income, productivity, food security, and decision-making domains.

The dose-response pattern-with more engaged participants showing larger gains-supports the interpretation that structured, women-focused extension can generate real socioeconomic shifts when delivered with adequate intensity and relevance.

Discussion

The 42.3% income gain among trained women surpasses the 20-25% improvements commonly observed in mixedgender extension programs across West Africa [9] , indicating that focused interventions may deliver stronger returns for women than gender-neutral approaches. The cassava yield improvement of 33.1% is consistent with results from www.extensionjournal.com women-focused farmer field schools in Uganda, where gains of 25-35% were documented [10] . The nutritional security improvement carries particular significance given that women's food security in this region is frequently constrained by limited decision-making authority over household resources. The rise in decision-making involvement-from 29.6% to 57.4%-may represent the most consequential finding. Extension programs seldom measure or explicitly target women's agency, yet this dimension likely serves as the pathway through which other benefits are maintained over time [11] . Women who acquire voice in household farming decisions are better equipped to invest in improved inputs and embrace new practices [12] .

It should be noted that the study spanned only 20 months and did not evaluate whether benefits endure beyond the structured training period. The comparison group also registered modest improvements, presumably reflecting routine extension exposure and favorable market conditions during the observation period [13] .

Limitations

The quasi-experimental design does not completely eliminate selection bias-women who joined registered farmer associations may be inherently more driven than the broader farming population. Self-reported earnings and decision-making data are susceptible to social desirability and recall bias. The 20-month observation window does not capture long-term sustainability. Findings from southwestern Nigeria may not transfer to other agroecological or cultural settings [14] .

Conclusion

Organized training interventions delivered through agricultural extension produced measurable socioeconomic gains for rural women farmers in Ogun and Ekiti States, Nigeria. Trainees recorded stronger income growth, higher crop yields, improved nutritional security, and markedly greater decision-making involvement compared with women receiving routine advisory services. The doseresponse pattern observed indicates that program intensity matters. Extension systems aiming to narrow gender gaps in agricultural productivity and household welfare should consider investing in organized, women-focused training rather than relying exclusively on mainstreaming gender within existing mixed-audience programming.
