Crop diversification enhances crop productivity and resilience and reduces vulnerability in smallholder farming systems . In Tanzania, diversified crop portfolios are associated with greater food security and dietary quality . In Kenya, levels of crop diversity are higher in villages affected by frequent droughts, which are the main cause of crop failure . Crop diversification also helps control pest outbreaks, which may become more frequent and severe under increased climate variability and extreme events . High farming diversity enables households to better meet food needs, but only up to a certain level of diversity , and the viability of and benefits from mixed farming are highly context dependent .
