Urban pearl millet farmers’ perceptions of climate change and adaptation strategies in Niamey commune V, the Sahel

Climate variability in the Niamey region presents a dual-faceted challenge. Yet most studies focus on broader farming systems. This study investigated the climate change perceptions and adaptation strategies developed by urban pearl millet farmers in Niamey Commune V, an area often overlooked in agricultural studies. Using snowball sampling, data were collected on socio-demographic and socio-economic characteristics, climate change perception, and adaptation strategies through structured interviews, focus group discussions, and analysis of 30 years of rainfall data (1991-2020). A sample of 150 pearl millet farmers aged at least 40 years was surveyed, and key informant interviews were conducted with the Agricultural Extension Unit. Descriptive statistics, statistical tests, and multinomial logistic regression were used to identify the determinants of adaptation strategy adoption. Findings revealed a high level of climate awareness among farmers over the past 30 years, which led to the adoption of both local and extension-based adaptation measures. Significant disruptions in rainfall were noted. Farmers primarily used soil fertility regeneration techniques, crop diversification, crop defense, improved seeds, organic fertilizers, adjusted planting calendars, water conservation techniques, and prayers or rituals to cope with these changes. Local practices aimed at improving productivity and climate adaptation, while extension-derived practices emphasized the synergy between productivity, adaptation, and mitigation. This research addresses a critical knowledge gap in how urban pearl millet farmers perceive and respond to climate change impacts. The study's findings are significant for urban agriculture policy, underscoring the need for timely climate information, effective extension services, and the integration of adaptive agricultural practices into urban planning. These steps are crucial for enhancing resilience and fostering sustainable development in urban agriculture.
