Covid-19 pandemic mitigation measures in the global South, particularly African developing countries like Nigeria were inadequate to alleviate socioeconomic effects of the pandemic on the livelihood and survival of rural communities. Rural women dominate the informal sector and have been active in agriculture, food security, health, nutrition, home management, traditional elderly care, and micro and small-scale enterprises. Whilst the effects of the pandemic on Nigerian rural women have been measured, the contribution of rural women to the sustainability of agrarian rural communities in the country have not been studied. This paper explored the role of women in supporting their families and communities for the sustainability of rural communities and challenges they faced as they serve as buffers for the survival of their families and sustenance of livelihood in rural communities during the pandemic. The paper adopted qualitative phenomenological research design. A sample of 30 rural women were drawn from Gbara Village, an agrarian rural community in Sagamu Local Government, Ogun State, Nigeria through convenience sampling and purposive sampling techniques. Semi-structured Interviews, focus group meetings, and documents were used as data sources and descriptive analysis was used to analyses the demographic characteristics of the respondents. The qualitative results were analyzed through content analysis and eight themes emerged. There were responses on contributions of rural women to the sustainability of Gbara Village during the pandemic in agriculture and food security value chain, health and nutrition, home management, traditional elderly care, and rural entrepreneurship. The paper also found that rural women were confronted with socio-economic challenges of gender inequalities, illiteracy, and limited access to technology to enhance their role as change agents in rural communities during the pandemic. The study suggested that the government, organized private sector, development agencies, non-governmental organizations, research institutions, and civil society organizations should priorities and fast-track the attainment of gender equality and women education to empower rural women and increase their capacity for socio-economic transformation of rural communities in Nigeria.
