The study examines the vulnerability of coffee-based farm households in Kerala’s Wayanad district, focusing on the panchayats of Vythiri, Ambalavayal, and Noolpuzha. Climate change significantly affects these regions, mainly due to altered rainfall patterns and temperature fluctuations impacting coffee production. The study uses data from 120 farmers and secondary climate information from 1991 to 2022 to analyze the vulnerability of Arabica and Robusta coffee varieties, which are highly sensitive to these climatic changes. Coffee, along with black pepper and areca nut, forms the dominant cropping systems in the region, with coffee being the primary crop. The vulnerability index indicates that Vythiri is the most vulnerable, Ambalavayal is moderately vulnerable, and Noolpuzha is the least vulnerable. Factors such as low literacy, excessive use of inorganic fertilizers, minimal subsidies, and water scarcity exacerbate the vulnerability of these households. To address these challenges, the study suggests improving irrigation infrastructure, developing weather-based crop insurance, providing localized weather information, promoting diseaseresistant black pepper varieties, and encouraging soil-based fertilizer applications. The findings emphasize the need for adaptive strategies and targeted policy interventions to reduce the vulnerability of small and marginal farmers in the coffee-based systems of Wayanad.
