Characterisation of Key Agro-Climatological Hazards and Assessment of Yam Farmers’ Agronomic Practices and Adaptive Responses
摘要
Yam (Dioscorea spp.) constitutes the leading staple crop in Côte d’Ivoire and a key source of livelihood for households in the Gontougo region. Because production relies entirely on rainfall, climate variability poses a major threat to its sustainability. The available research has been conducted to characterize the agro-climatological hazards and assess yam farmers’ perceptions and adaptation measures. A mixed approach was used, combining climate indices (rainfall and temperature extremes, onset and cessation of the rainy season) with household surveys across four departments of Gontougo. Results indicate that farmers are particularly concerned with rainfall irregularities, declining soil fertility, rising surface temperatures, and reduced yields. In response, they adopt strategies such as diversifying cropping environments, adjusting planting calendars, and integrating local knowledge with advisory services provided by ANADER. Despite these efforts, most producers perceive limited capacity to cope with climate change. The findings highlight the urgent need for planned adaptation policies and institutional support to strengthen local resilience.
