This thesis portrays the role of human behaviour in the shape of individual and community resilience to covariate shocks from different angles 1 . The focus of this thesis is on farmers' individual and collective responses to floods and pests, and how these influence the resilience of their livelihoods at the household and community levels.

Over 70% of the world's farmers are smallholders (with less than 2 hectares), producing over 50% of the total world's crop production, and over 80% of the food consumed in the Global South (Ricciardi et al., 2018, Samberg, et al 2016.Smallholders' develop and maintain their livelihoods under insecure conditions that often involve high degrees of exposure to various threats often related to their geographical location (i.e. floods in lowlands, drought in semi-arid areas, and landslides in mountainous areas) (
